ABSTRACT
Abstract HIV risk perception and Intimate partner violence (IPV) are related to HIV infection in women. However, there is a lack of information regarding on the association between risk perception and IPV in the Mexican population. This study aimed to identify and characterize subgroups based on their risk perception through the analysis of latent classes and to evaluate the variables associated with HIV risk perception. An online survey was conducted to assess sexual and preventive behavior, HIV risk perception, and intimate partner violence. Three hundred thirty-two women participated; the sampling was for convenience. Two latent classes were identified: a group with risk perception (85%) and one without risk perception (14.6%). The variables associated with the risk perception were a sexual attraction to men, not having a stable partner, perceiving oneself as at risk of acquiring HIV due to sexual behavior, and the presence of IPV. HIV prevention programs for women must address the stigmas related to HIV, such as the idea that the risk only occurs when they have multiple sexual partners, promote accurate HIV risk perception and prevent IPV in all its expressions and contexts.
Resumen En mujeres, la violencia de pareja está relacionada a una mayor probabilidad de adquirir la infección por VIH. De igual forma, una inadecuada percepción de riesgo de adquirir el virus coloca a las mujeres en una situación vulnerable. Existe una falta de información ente la asociación de la VPI y la percepción de riesgo es mujeres mexicanas. Este estudio persiguió dos objetivos: el primero fue identificar y caracterizar subgrupos en función de su percepción de riesgo a través del análisis de clases latentes; el segundo objetivo consistió en evaluar las variables asociadas con la percepción de riesgo de VIH. Se realizó una encuesta en línea para evaluar el comportamiento sexual y preventivo, la percepción del riesgo de VIH y la VP. Participaron 332 mujeres; el muestreo fue por conveniencia. Se identificaron dos clases latentes: un grupo con percepción de riesgo (85%) y otro sin percepción de riesgo (14,6%). Las variables asociadas a la percepción de riesgo fueron atracción sexual por hombres, no tener pareja estable, percibirse en riesgo de adquirir el VIH por la conducta sexual y haber sufrido de violencia de pareja en los últimos seis meses. Se concluye que los programas de prevención del VIH para mujeres deben abordar los estigmas relacionados con el VIH, como la idea de que el riesgo solo ocurre cuando tienen múltiples parejas sexuales, promover una percepción precisa del riesgo del VIH y principalmente, prevenir la VP en todas sus expresiones y contextos; así como también dar atención personalizada a mujeres que ya sufren de violencia de pareja.
ABSTRACT
Abstract The purpose of the cross-sectional study was to identify patterns of modifiable lifestyle behaviors and examine the relationship between sociodemographic characteristics and distinct lifestyle behaviors. The data were gathered from the National Health Survey 2019, a study that included adults with diabetes. Four domains of lifestyle behaviors were used to define these behaviors: smoking, alcohol consumption, physical activity, and diet. The association between patterns of lifestyle behaviors and variables of interest was assessed using multinomial regression analysis. The three lifestyle patterns identified were: Class 1, referred to as "unhealthy diet," comprised 17.0% of the sample and was characterized by unhealthy eating habits; Class 2 (less active and insufficient fruit and vegetable intake) represented 71.2% of the sample; Class 3 referred to as "low risk" (11.8%) is characterized by a lower probability of engaging in most risky behaviors. A person over 45 years of age with little or no education and no health care coverage was less likely to be a member of Class 1. Male individuals who do not attend a doctor regularly exhibited more chances of belonging to Class 2. Mixed-race individuals aged 45 years or more with a low level of education have a lower chance of belonging to this class.
Resumo Neste estudo de caráter transversal objetivou-se identificar os padrões de comportamento de estilo de vida e sua associação com características sociodemográficas. Utilizou-se como base de dados a Pesquisa Nacional de Saúde de 2019, com adultos (≥ 18 anos) diabéticos. Os padrões de saúde foram definidos pela Análise de Classes Latentes em quatro domínios: tabagismo, consumo de bebidas alcoólicas, atividade física e alimentação. Foi aplicada análise de regressão multinominal para identificar a associação entre os padrões de comportamento e as variáveis sociodemográficas de interesse. Identificou-se três padrões de comportamento: a Classe 1 corresponde a 17% da amostra e compreende indivíduos com maior probabilidade de comportamentos de risco ligados à alimentação; a Classe 2 (baixos nível de atividade física e consumo de frutas e hortaliças) compreende 71,2% da amostra; e a Classe 3 (11,8% da população) reúne os indivíduos com menor chance de desenvolver comportamentos de risco. Indivíduos com 45 anos ou mais, com baixa escolaridade e sem plano de saúde têm menos chances de pertencer à Classe 1. Homens, que não fazem visitas regulares ao médico têm maiores chances de pertencer à Classe 2, bem como aqueles com 45 anos ou mais, com baixa escolaridade.
ABSTRACT
Resumen Estudios sugieren la presencia de patrones de violencia en las relaciones de noviazgo durante la adolescencia. En la población adolescente mexicana se conoce poco sobre los patrones de abuso cara a cara y digital en el noviazgo y cómo pueden ser explicados por el consumo de alcohol. El objetivo de esta investigación fue identificar los patrones de victimización por abuso en las relaciones de noviazgo y determinar si el consumo de alcohol predice los patrones encontrados. Fue un estudio transversal con alcance explicativo. Participaron 398 adolescentes estudiantes (62.8% mujeres) de 15 a 18 años de edad (M = 16.1 años; DT = 1). Se usó un análisis de clases latentes y se encontraron tres clases: 1) violencia generalizada baja (45%), 2) violencia psicológica moderada y control digital alto (38%) y 3) violencia generalizada alta (17%). Se encontró que el consumo de alcohol se asoció con la pertenencia a la clase de violencia psicológica moderada y control digital alto (β = 0.48, p = .022) y con la pertenencia a la clase de violencia generalizada alta (β = 0.66, p = .004). Es importante considerar, en la generación de intervenciones, la existencia de patrones de violencia en el noviazgo en adolescentes y la influencia que tiene el consumo de alcohol sobre estos.
Abstract Studies suggest the existence of patterns of dating violence during adolescence. In the adolescent Mexican population, little is known about the patterns of face-to-face and cyber dating abuse and to what extent they can be explained by alcohol consumption. The aim of this research was to identify patterns of dating abuse victimization and to determine whether alcohol use predicts the patterns found. It was a cross-sectional study with an explanatory scope. A total of 398 adolescent students (62.8% women) from 15 to 18 years of age (M = 16.1 years; SD = 1) participated in the study. Latent class analysis was used, and three classes were found: 1) low generalized violence (45%); 2) moderate psychological violence and high digital control (38%); and 3) high generalized violence (17%). Alcohol consumption was found to be associated with the membership in the moderate psychological violence and high digital control (β = 0.48, p = .022) and were included in the high generalized violence class (β = 0.66, p = .004). It is important to consider, in the generation of interventions, the existence of patterns of violence in dating relationships among adolescents and the influence that alcohol consumption has on them.
ABSTRACT
Purpose: To assess the perception of college?going girls toward corneal donation in Northern India. Methods: An online survey with a pre?structured, pre?validated questionnaire was conducted on 1721 college?going girls in Northern India. The knowledge and attitude scores were regressed, and latent class analysis was carried out. Results: The average of scores for all participants was computed individually for the knowledge questions and the attitude questions, and based on this score, total participants were divided into two groups: Better corneal donation behaviors (BCDB) and poor corneal donation behaviors. The binomial logistic regression model of knowledge domain for predicting BCDB, age of the participant, their awareness about corneal donation, and willingness to discuss eye donation among family members were found significant. Similarly, for the attitude domain, awareness about corneal donation, knowledge about hours within which ideal eye donation needs to be undertaken, and knowledge about eye donation during coronavirus disease 2019 (COVID?19) pandemic were found to be significant. Latent class analysis identified one subset of participants having poorer knowledge and attitude scores and that they were more from a rural background, were having more than first order as birth order, were belonging to SC/ST classes, had illiterate or secondary education of father and mother, and were living in rented houses. Conclusion: The findings of the study significantly contribute to devising a mechanism to improve knowledge and influencing the attitude about eye donation among the youth, especially young women, who can act as counselors and motivators for the masses as well as their own families, in the generations to come.
ABSTRACT
Objective:To explore the latent classes of emotional behavior of children with mental disorders, and their relationship with parents' sense of parenting competence and psychological distress.Methods:A survey of 327 parents of children with mental disorders was conducted from September to December 2022 using the general information questionnaire, the sense of parenting competence scale, the Kessler psychological distress scale, and the strengths and difficulties questionnaire (parent version). Mplus 8.0 and SPSS 25.0 softwares were used for statistical analysis.The latent class analysis was used to identify subgroups of children with mental disorders based on their emotional behavior.Multinomial logistic regression was used to analyze the related factors.Results:Latent class analysis showed that the emotional behaviors of children with mental disorders were divided into 3 categories: emotion-conduct problem prominent group (38.53%(126/327)), simple emotional problem group (44.65%(146/327)), and emotion-peer interaction significant group (16.82%(55/327)). The differences among the 3 latent classes were statistically significant (all P<0.05) in terms of parents' parenting competence, satisfaction, and psychological distress scores.Compared with the emotion-conduct problem prominent group, the higher the parental parenting knowledge and parenting competence, the emotional behavior of children with mental disorders tended to be in the simple emotional problem group ( B=0.699, OR=2.011, 95% CI=1.046-3.868; B=0.088, OR=1.092, 95% CI=1.017-1.173). Compared with the " emotion-conduct problem prominent group" , the emotional behavior of children with mental disorders aged 13 to 18 years old tended to be in the " emotion-peer interaction significant group" ( B=1.982, OR=7.255, 95% CI=1.637-32.141). Conclusion:The emotional behavior of children with mental disorders is heterogeneous, and there are differences in sense of parenting competence and psychological distress of parents among different latent classes of children with mental disorders.
ABSTRACT
Objective:To explore the latent classes of parental feeding behaviors in preschool children, and to examine the relationship between potential types of parental feeding behaviors and parental depression status.Methods:From May to July 2021, parents of preschoolers from eight kindergartens in Shanghai were recruited and investigated.A paper-based questionnaire consisting of the Chinese preschooler’s caregivers’ feeding behavior scale (CPCFBS) and the center for epidemiological studies depression scale (CESD-10) was employed.Finally, a total of 1 006 valid questionnaires were retrieved.Mplus 8.0 and SPSS 26.0 were used for statistical analysis.The latent class analysis was used to identify subgroups of parents based on their feeding practices.Multinomial Logistic regression was used to examine the relevant influencing factors.Results:The feeding behaviors of parental of preschool children could be divided into four potential categories: " high responsiveness and high non-responsiveness type" (24.55%), " low responsiveness and high non-responsiveness type" (27.44%), " high responsiveness and low non-responsiveness type" (28.33%) and " low responsiveness and low non-responsiveness type" (19.68%). The parents with depression status were less likely to be categorized as " high responsiveness and low non-responsiveness type" ( OR=0.386, 95% CI: 0.218-0.684). The parents with older children were more likely to be categorized as " low responsiveness and low non-responsiveness type" ( OR=1.318, 95% CI: 1.039-1.672). Conclusion:The feeding practices of parents of preschool children can be categorized into four latent classes.The parents with depression status are more likely to adopt non-responsive feeding practice than responsive feeding practice.Actively paying attention to and improving the depression status of parents may help the feeder to adopt scientific feeding behavior.
ABSTRACT
Objective:To explore the potential categories of prostate cancer patients′ participation in shared decision making, and analyze the characteristics and influencing factors of different categories of prostate cancer patients′ participation, so as to provide theoretical support for improving prostate cancer patients′ participation in shared decision making.Methods:This was a cross-sectional study. A total of 292 patients with a first diagnosis of prostate cancer without metastasis from three tertiary grade A hospitals in Zhengzhou were selected from October 2019 to October 2020 (Henan Provincial People′s Hospital, the First Affiliated Hospital of Zhengzhou University, the First Affiliated Hospital of Henan University of Chinese Medicine). The general data questionnaire, the Decisional Engagement Scale, Perceived Social Support Scale and Disease Uncertainty Scale were used. Latent class analysis was used to classify prostate cancer patients according to shared decision making participation, and Logistic regression was used to analyze the influencing factors of the potential category.Results:The total scores of the Decisional Engagement Scale, Perceived Social Support Scale and Disease Uncertainty Scale in prostate cancer patients were (67.28 ± 20.77), (62.34 ± 15.39), (95.06 ± 8.05) points, respectively. The shared decision making participation of prostate cancer patients was divided into three potential categories: high participation group 76.4%(223/292), moderate participation group 12.7%(37/292), and low participation group 11.0%(32/292). Taking high participation group as reference, age( OR=1.088, 95% CI 1.161-1.231, P<0.05) and illness uncertainty( OR=1.480, 95% CI 1.414-1.919, P<0.05) were the risk factors for the low participation group; perceived social support was the protective factor ( OR=0.857, 95% CI 0.775-0.946, P<0.05). Illness uncertainty was the risk factor( OR=1.525, 95% CI 1.316-1.767, P<0.05), and perceived social support was the protective factor ( OR=0.829, 95% CI 0.838-0.949, P<0.05) for the moderate participation group. Conclusions:There were obvious classification characteristics of shared decision making participation for prostate cancer patients. Age, perceived social support and illness uncertainty were the influencing factors of it. Interventions should be taken according to the characteristics of each category, to improve the level of shared decision making of prostate cancer patients.
ABSTRACT
Objective:To explore the potential categories of resourcefulness in primary caregivers of stroke patients and analyze the differences in the characteristics of different types of caregivers, so as to provide basis for clinical construction of effective intervention plans.Methods:The 308 primary caregivers of stroke patients who met the research standards in the Department of Neurology of General Hospital of Ningxia Medical University, People′s Hospital of Ningxia Hui Autonomous Region, the First People′s Hospital of Yinchuan from December 2020 to August 2021 were selected as the research objects by convenient sampling method.The general information questionnaire, Resourcefulness Scale and Social Support Revalued Scale were used for cross-sectional investigation.Results:The resourcefulness of the primary caregivers of stroke patients were divided into 2 potential categories: low resourcefulness group (62.7%, 193/308) and high resourcefulness group (37.3%, 115/308). Uni-variate analysis showed that there were differences between potential categories: age and education level of stroke patients, whether there was long-term medication history, number of other chronic diseases, had there been any complications due to illness, age, education level and occupation of caregivers, average daily care duration, family relations, and social support ( χ2 values were -3.34 - 23.62, all P<0.05). Logistic regression analysis showed that social support and education level of caregivers were the influencing factors of caregiver resourcefulness ( P<0.05). Conclusions:The resourcefulness in the primary caregivers of stroke patients has certain characteristics. Clinically, targeted intervention measures should be formulated according to the different types of caregiver resourcefulness characteristics of caregivers and their influencing factors to improve the caregiver resourcefulness of stroke patients.
ABSTRACT
Objective To investigate the food preferences and explore the potential association between dietary knowledge and food preferences in residents aged 18 and over in China,so as to provide a basis for promoting healthy diets.Methods The latent class analysis was carried out with the 2015 cross-sectional data of China health and nutrition survey to categorize the food preferences among 8 783 residents aged 18 and over.Multinomial Logistic regression was adopted to assess the association between and dietary knowledge and food preferences.Results The food preferences of the residents aged 18 and over in China were classified into preference for less vegetable(3.28%),lack of preference(11.20%),diverse preferences(4.19%),and preference for healthy diets(81.33%).The proportion of the adults with dietary knowledge was 36.87%(3 238/8 783).The dietary knowledge varied in the adults with different food preferences(all P<0.001).After adjusting for gender,age,urban and rural distribution,education background,and annual household income,for each point increase in the dietary knowledge score,there was an estimated reduction of 22% in the probability of preferring less vegetables(OR=0.78,95%CI=0.76-0.80, P<0.001),13% in the probability of lacking preference(OR=0.87,95%CI=0.86-0.89, P<0.001),and 3% in the probability of having diverse preferences(OR=0.97,95%CI=0.94-1.00, P=0.030).Compared with those lacking dietary knowledge,the individuals with dietary knowledge had a 77% less probability of preferring less vegetables(OR=0.23,95%CI=0.16-0.32, P<0.001),a 55% less probability of lacking preference(OR=0.45,95%CI=0.39-0.53, P<0.001),and a 23% less probability of having diverse preferences(OR=0.77,95%CI=0.61-0.96, P=0.023).Conclusions The residents aged 18 and over in China presented four food preferences,including preference for less vegetables,lack of preference,diverse preferences,and preference for healthy diets,the last of which had the highest proportion.The individuals with lower levels of dietary knowledge have higher probability of preferring unhealthy food.

Objective To analyze the characteristics of work-related musculoskeletal disorders (WMSDs) among sonographers in Guangdong Province, and to explore the disease pattern of the cases. Methods A total of 512 sonographers from 31 hospitals in Guangdong Province were selected as the research subjects using stratified cluster sampling method. The prevalence of WMSDs in the past year was investigated using the Musculoskeletal Disorders Questionnaire, and the characteristics of WMSDs were analyzed. Latent class analysis was used to identify the disease pattern of WMSDs. Results The overall prevalence of WMSDs was 94.3%. The top five affected body parts were right shoulder, neck, right hand/wrist, lower back and right forearm/elbow, with the prevalence of 80.3%, 75.4%, 61.1%, 55.5% and 45.3%, respectively. The prevalence of WMSDs was higher on the right side for the shoulder, hand/wrist, forearm/elbow, hip/leg and knee compared with the left side (80.3% vs 31.3%, 61.1% vs 13.9%, 45.3% vs 10.0%, 17.4% vs 8.6%, 13.1% vs 8.4%, all P<0.05). The prevalence of WMSDs increased with work years, as well the prevalence of WMSDs in the top five affected body parts among the sonographers (all P<0.05). However, there were no statistical differences in prevalence of WMSDs between general hospitals and maternal and child health hospitals, tertiary hospitals and non-tertiary hospitals, Pearl River Delta hospitals and non-Pearl River Delta hospitals; there was also no statistical difference between different genders and age groups of the sonographers (all P>0.05). The best-fit latent disease pattern for sonographers WMSDs comprised three categories： symptom of neck-right shoulder, symptom of neck-lower back-right shoulder-right elbow-right hand/wrist, and symptom of multi-parts above the knees, with the latent probabilities of 0.438, 0.427 and 0.135, respectively. Conclusion The prevalence of WMSDs in sonographers is extremely high, with a dose-effect relationship with work years. The most common affected parts are neck, lower back and right shoulder, right hand/wrist, and right forearm/elbow. The prevalence of WMSDs in the right side of limb was higher than that in the left. WMSDs primarily occur in multiple parts simultaneously. The most common symptoms occur in the neck-right shoulder and neck-lower back-right shoulder-right elbow-right hand/wrist.
ABSTRACT
Objective@# To explore the trajectory of the development of permanent caries in 12- to 16-year-old students in Liuyang and to provide a reference for the prevention and management of caries.@*Methods@#Primary and secondary school students who were registered within the Liuyang jurisdiction were screened for caries from September to November by the Liuyang Center for Disease Control and Prevention. A total of 7 297 students between the ages of 12 and 16 years with complete permanent dentition caries monitoring records and traceable deciduous dentition caries monitoring records were selected from 2013 to 2019, and a zero-inflated negative binomial-latent class growth model (ZINB-LCGM) was established to describe the trajectory of the development of individual caries using the decayed missing filled teeth (DMFT) indicators. @*Results@# DMFT of 12- to 16-year-old students in Liuyang were mainly decayed teeth (DT), with the majority occurring in the first permanent molar. According to the ZINB-LCGM model, the students were classified into three latent categories, "slow growth pattern" (28.55%), "rapid growth pattern" (6.59%), and "stable pattern" (64.86%), which followed different nonlinear caries growth trajectories. Females with deciduous teeth caries were more likely to have trajectories showing a “rapid growth pattern” and a “slow growth pattern”. There were significant differences in the trajectories between men and women, as well as between those with and without primary dentition caries. @*Conclusion @# The trajectory of the development of caries in 12-16-year-old students shows heterogeneity in terms of different developmental patterns of latent categories, suggesting that females with deciduous dental caries should receive more attention.
ABSTRACT
Abstract: This study aimed to identify patterns of metabolic syndrome among women and estimate their prevalence and relationship with sociodemographic and biological characteristics. In total, 5,836 women were evaluated using baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Patterns of metabolic syndrome were defined via latent class analysis, using the following metabolic abnormalities as indicators: abdominal obesity, hyperglycemia, hypertension, hypertriglyceridemia, and reduced HDL cholesterol. The relationship between these patterns and individual characteristics was assessed using latent class analysis with covariates. Three patterns of metabolic syndrome were identified: high metabolic expression, moderate metabolic expression, and low metabolic expression. The first two patterns represented most women (53.8%) in the study. Women with complete primary or secondary education and belonging to lower social classes were more likely to have higher metabolic expression. Black and mixed-race women were more likely to have moderate metabolic expression. Menopausal women aged 50 years and older were more often classified into patterns of greater health risk. This study addressed the heterogeneous nature of metabolic syndrome, identifying three distinct profiles for the syndrome among women. The combination of abdominal obesity, hyperglycemia, and hypertension represents the main metabolic profile found among ELSA-Brasil participants. Sociodemographic and biological factors were important predictors of patterns of metabolic syndrome.
Resumo: O objetivo foi identificar padrões de síndrome metabólica em mulheres, estimar suas prevalências e relações com características sociodemográficas e biológicas. Este estudo examinou 5.836 mulheres utilizando dados da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Os padrões de síndrome metabólica foram definidos por meio de análise de classe latente, usando as seguintes anormalidades metabólicas como indicadores: obesidade abdominal, hiperglicemia, hipertensão, hipertrigliceridemia e colesterol HDL reduzido. As relações entre os padrões de síndrome metabólica e as características individuais foram avaliadas por meio da análise de classes latentes com covariáveis. Foram identificados três padrões de síndrome metabólica, denominados "alta expressão metabólica", "expressão metabólica moderada" e "baixa expressão metabólica". Os dois primeiros padrões representaram a maioria (53,8%) das mulheres do estudo. As mulheres com nível de escolaridade primário ou secundário e pertencentes à classe social baixa tiveram maior chance de apresentar maior expressão metabólica. Negros e pardos tiveram maior chance de apresentar "expressão metabólica moderada". Mulheres na menopausa com 50 anos ou mais apresentaram maior chance de ter padrões de maior risco à saúde. Este estudo abordou a natureza heterogênea da síndrome metabólica, identificando três perfis distintos para a síndrome entre as mulheres. A combinação de obesidade abdominal, hiperglicemia e hipertensão representa o principal perfil metabólico encontrado entre os participantes do ELSA-Brasil. Fatores sociodemográficos e biológicos foram importantes preditores para os padrões de síndrome metabólica.

ABSTRACT
Abstract This study aimed to explore the pathways that can influence cigarette smoking among adolescents. This population-based cohort followed a random sample of 12-year-old adolescents from southern Brazil for 6 years. Regular cigarette smoking was assessed through a self-reported question, previously used in the Brazilian National Survey of Scholar Health. We also gathered data on bullying, dental caries at baseline, incidence of caries, sex, friend network, and Sense of Coherence (SOC). Socioeconomic and demographic characteristics were also collected. Structural equation modeling was used to evaluate the pathways. Of the 1,134 adolescents examined at baseline, 768 were re-evaluated (67.7% retention rate). The prevalence of smoking was 37.6%. This prevalence was directly affected by low SOC (SC: -0.14, p < 0.01), low household income (SC: -0.12, p < 0.01), and male sex (SC: 0.15, p < 0.01). Presence of dental caries at baseline indirectly influenced the occurrence of dental bullying at follow-up via the incidence of dental caries (SC: 0.01, p < 0.05). Dental bullying indirectly influenced cigarettes consumption via SOC (SC: 0.62, p < 0.05). Friend network also indirectly influenced the consumption of cigarettes via SOC (SC: 0.32, p < 0.05). Psychosocial factors influence adolescent cigarette consumption through its higher direct and indirect effects (via bullying). In addition, behavioral, sociodemographic, and clinical factors also influence the occurrence of smoking.
ABSTRACT
Purpose: To evaluate the association of daily screen time and quality of sleep with the prevalence of dry eye among college?going women. Methods: This study was a cross?sectional, comparative questionnaire?based study of 547 college?going women in northern India. A 10?item Mini Sleep Questionnaire was used to check the quality of sleep, and the Standard Patient Evaluation of Eye Dryness (SPEED) scale was used to examine the prevalence of dry eye among college?going women. Results: Multinomial logistic regression showed a significant association between dry eye with daily screen time spent (P < 0.05) and the quality of sleep (P < 0.05) among college?going girls. Using Latent Class Analysis, two latent classes were selected based on the Bayesian Information Criteria. It was found that the majority population falls in class two and was having Severe Sleep?Wake difficulty. It was seen that the participants in class two belonged to the age bracket of 18–21 years, were from stream Humanities, education of father and mother equal to graduation, father working only, belonging to the nuclear family, having one sibling, hailing from the urban locality, spending more than 6 h daily on?screen, a majority of them using mobile phones, not using eye lubricants, and reported an increase in screen time during COVID?19. Conclusion: Dry eye and sleep quality are essential global health issues, and coupled with increased screen time, may pose a challenge in the present era. Preventive strategies need to be incorporated in school and college curriculums to promote physical, social, and psychological well?being and quality of life

ABSTRACT
Objective:To explore the changing track of cancer-related fatigue in patients with lung cancer during perioperative period and analyze its influencing factors.Methods:From December 2020 to May 2021, 162 eligible patients with lung cancer were selected in the First Affiliated Hospital of Shandong First Medical University & Shandong Provincial Qianfoshan Hospital by convenient sampling method. Mental resilience and social support were investigated before operation (T0);and cancer-related fatigue was investigated before operation (T0),3 days after operation (T1), 1 week after operation (T2), 2 weeks after operation (T3) and 1 month after operation (T4), and Latent Class Growth Model was used to identify the track categories. Logistic regression analysis was used to analyze the influencing factors.Results:Three cancer-related fatigue tracks were fitted in this study, which were no fatigue group (31.7%), increased fatigue group (36.0%) and sustained fatigue group (32.3%). Univariate analysis showed that smoking history ( χ2=14.83, P<0.05), BMI ( χ2=29.67, P<0.05), hemoglobin count ( F=4.57, P<0.05), mental resilience ( F=35.53, P<0.05), social support ( F=47.53, P<0.05) were related to the track category of cancer-related fatigue. Logistic regression analysis showed that smoking history, over weight/obesity, resilience and social support were the predictors of cancer-related fatigue locus ( P<0.05). Conclusions:Perioperative cancer-related fatigue of patients with lung cancer has different change trajectories, patients with higher BMI and lower resilience are more likely to have a tendency of persistent fatigue. Patients with smoking history and lower social support are more likely to have an upward trend of fatigue.

Os objetivos do estudo foram identificar perfis de vizinhança percebidos por adolescentes e adultos jovens, e estimar sua associação com a realização de atividade física global e de lazer. Utilizaram-se dados de 1.637 indivíduos entre 15 e 24 anos, de um estudo transversal, com amostragem por conglomerados, de uma cidade do Estado da Bahia, Brasil, em 2011. A atividade física foi mensurada pelo International Physical Activity Questionnaire (IPAQ), versão curta, além de questão sobre atividade no lazer. A percepção de características do ambiente físico e social da vizinhança se baseou em escala com 14 questões. Perfis de vizinhança foram definidos por meio de análise de classes latentes (LCA), e a estimação dos seus efeitos na atividade física usou o modelo com respostas distais. A análise de perfil latente resultou em três padrões de vizinhança, descritos como "urbana, sociável e favorável à atividade física - classe 1" (39,6%); "sociável e segura - classe 2" (24,4%); e "insegura, de baixa sociabilidade - classe 3" (36%). Os indivíduos pertencentes à "classe 1" apresentaram maior probabilidade de se exercitar (56,4%), enquanto, para as classes 2 e 3, estes percentuais corresponderam a 46,3% e 42,8%, respectivamente. Associação estatisticamente significante foi identificada apenas na classe "urbana, sociável e favorável à atividade física", cuja chance de realizar atividade de lazer foi de 72% (OR = 1,72; IC95%: 1,29-2,29). Bairros com atributos favoráveis à prática de atividade física e a existência de elementos de urbanização aumentam a chance do comportamento ativo no lazer entre os adolescentes e adultos jovens. O uso de LCA e do modelo com repostas distais é promissor e inovador na abordagem sobre vizinhança.
This study aimed to identify neighborhood profiles perceived by adolescents and young adults and estimate their association with global and leisure-time physical activity. Data from 1,637 individuals aged 15 to 24 years were taken from a cross-sectional study with cluster sampling, conducted in a city in the State of Bahia, Brazil, in 2011. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ), short version, in addition to a question about leisure activities. The perception of characteristics of the physical and social environment of the neighborhood was based on a scale with 14 questions. Neighborhood profiles were defined through latent class analysis (LCA), and the estimation of their effects on physical activity used a model with distal outcomes. The latent profile analysis resulted in three neighborhood patterns, described as "urban, sociable, and favorable to physical activity - class 1" (39.6%); "sociable and safe - class 2" (24.4%), "insecure, low sociability - class 3" (36%). Individuals belonging to "class 1" showed the highest probability to exercise (56.4%), while for classes 2 and 3 these percentages corresponded to 46.3% and 42.8%, respectively. A statistically significant association was identified only in the "urban, sociable and favorable to physical activity" class, whose chance of performing leisure activities was 72% (OR = 1.72; 95%CI: 1.29-2.29). Neighborhoods with attributes that favor the practice of physical activity and the existence of urbanization elements increase the chance of active leisure behavior among adolescents and young adults. The use of LCA and the model with distal outcomes are promising and innovative in neighborhood approaches.

Los barrios con atributos favorables para la actividad física y la existencia de elementos de urbanización aumentan la posibilidad de un comportamiento activo en el ocio entre los adolescentes y los adultos jóvenes. El uso de ACL y el modelo con respuestas distales son enfoques prometedores e innovadores para la vecindad.
ABSTRACT
Abstract Determinants of oral diseases include behaviors, which in turn are influenced by a series of social determinants such as psychosocial aspects and dental care services. Therefore, the aim of this study was to investigate whether depressive symptoms and use of dental care services mediate the relationship between socioeconomic status (SES) and oral health behaviors. This was a cross-sectional study that analyzed data from participants in the 2019 National Health Survey (PNS) (n = 88,531). The eligibility criteria were individuals who were 18 years and older and exclusion criterion was living in households located in special or sparsely populated census tracts. Structural equation modeling (SEM) was used to test direct and indirect pathways from a latent variable for SES to oral health through depressive symptoms (assessed through the "Patient Health Questionnaire-9") and use of dental care services. The maximum likelihood estimator for complex samples with the robust standard error was used. The final model presented an adequate fit: RMESA of 0.008, CFI of 0.998, and SMRM of 0.005. The results showed that higher SES was directly associated with better oral health-related behaviors [standardized coefficient (SC): 0.428; p < 0.01] and indirectly through depressive symptoms [(SC): 0.002; p < 0.01] and dental care services [(SC): 0.089; p < 0.01]. The total effect of SES on oral health-related behaviors was equal to [(SC: 0.519 (p < 0.01)]. In conclusion, the findings suggest that high socioeconomic status, mediated by depressive symptoms and dental care services, has a positive effect on oral health.
ABSTRACT
O objetivo geral desta tese foi conhecer as magnitudes e os padrões das violências no namoro na adolescência (VNA) e das violências familiares na infância (VFI), as repercussões da VFI nos diferentes padrões de VNA, bem como as relações entre os padrões de VFI e a saúde mental na adolescência. O objetivo geral suscitou três objetivos específicos, cada um explorado em um manuscrito. Os dados usados na tese derivaram da pesquisa "Estupro de vulnerável e outras violências contra adolescentes e jovens do sexo feminino", desenvolvida em 2017 e 2018 que contou com a participação de 721 estudantes de escolas públicas e privadas da IX Região Administrativa (RA) do Rio de Janeiro. Para identificar a VNA, a VFI e estimar a saúde mental, usou-se respectivamente as versões brasileiras do instrumento Conflict in Adolescent Dating Relationships Inventory (CADRI), do Childhood Trauma Questionnaire (CTQ) e do General Health Questionnaire (GHQ-12). As estratégias de análise de dados variaram em função dos diferentes objetivos/manuscritos. O manuscrito 1 estimou as magnitudes de exposição e perpetração das VNA entre os escolares da IX RA do município do Rio de Janeiro. A prevalência de vitimização variou de 16,7% (sexual) a 94,6% (emocional). A prevalência de perpetração variou entre 9,9% (sexual) e 94,6% (emocional). Os adolescentes que relataram serem vítimas de violência na infância, os que vivem em áreas violentas e os que consomem bebidas alcoólicas com maior frequência tiveram maior prevalência de VNA. Os manuscritos 2 e 3 utilizaram análises de classes latentes (ACL) para identificar os padrões de VNA (manuscrito 2) e o padrão de VFI (manuscrito 3) com base na agregação de indivíduos em classes, caracterizadas em função da probabilidade de endosso aos diferentes itens dos instrumentos CADRI e CTQ. Além da identificação destes padrões, buscou-se utilizar as classes estimadas em modelos causais aferindo os efeitos das dimensões de VFI para os padrões de VNA (manuscrito 2) e das classes de VFI para a saúde mental dos adolescentes (manuscrito 3). No manuscrito 2, identificou-se três classes latentes de VNA entre meninas e meninos. O abuso sexual na infância aumentou a chance de pertencer à classe mais grave de vitimização de VNA entre as meninas (OR = 5,72; IC 95% = 2,51-13,06). Os abusos emocionais (OR=5,97; IC 95% = 1,95-18,30) e físicos (OR=3,16; IC 95%=1,07-9,34) aumentaram as chances de classificar os meninos na classe mais grave de perpetração de VNA. A ACL do manuscrito 3 também identificou três classes de violência familiar na infância, tanto em meninas, como em meninos. Apesar de várias semelhanças entre as classes dos dois sexos, as meninas foram mais vítimas de abuso sexual e os meninos de punição corporal (castigo físico). Pertencer à classe mais grave de VFI aumentou os escores do GHQ-12 em 2 a 3 pontos quando comparados às classes mais brandas de violência. A partir destes resultados e com as discussões trazidas pelos três manuscritos, espera-se que esta tese tenha contribuído tanto com as discussões temáticas das violências, como apresentado alguns avanços metodológicos no campo da análise epidemiológica. Com relação aos primeiros aspectos, mais uma vez, evidenciou-se que a violência entre pais e filhos é um problema de saúde pública, por sua alta frequência e relações diretas e especificas com a violência no namoro de adolescentes; ampliou-se também os debates sobre a relação entre as violências e o gênero, na medida em que tanto as prevalências como os padrões de violência diferem entre meninos e meninas desde a infância; identificou-se padrões de violência que mostram que a vivência de diferentes tipos de abuso é a situação mais frequente entre crianças e adolescentes; percebeu-se que as repercussões das violências contra crianças na saúde mental de adolescentes dependem do padrão de coocorrência das diferentes formas de vitimização infantil. Com relação aos avanços metodológicos, a tese é inovadora por propor, pela primeira vez no Brasil, a utilização de ACL para caracterizar as violências contra crianças e em relacionamentos amorosos de adolescentes. Ademais, a tese avança ao articular a identificação de padrões de violência via análise de classes latentes com seus fatores de risco e consequências, ampliando as possibilidades de inferência dos modelos.
The main objective of this thesis was to know the magnitudes and patterns of dating violence in adolescence (DV) and family violence against children (VAC), the repercussions of on different DV patterns, and the relationship of VAC patterns to health mentality in adolescence. The general objective raised three specific goals. Each one was explored in one manuscript. The data used in the thesis were derived from the research "Rape of the vulnerable and other violence against female adolescents and young people", developed in 2017 and 2018, with 721 students from public and private schools in the IX Administrative Region (AR) of Rio de Janeiro. The Brazilian versions of the Conflict in Adolescent Dating Relationships Inventory (CADRI) instrument, the Childhood Trauma Questionnaire (CTQ) and the General Health Questionnaire (GHQ-12) were used to identify DV, VAC and to estimate mental health trends respectively. Data analysis strategies varied according to different objectives/manuscripts. Manuscript 1 estimated the magnitudes of exposure and perpetration of DV among students from the IX AR in Rio de Janeiro. The estimated victimization prevalence ranged from 16.7% (sexual) to 94.6% (emotional). The prevalence of perpetration ranged from 9.9% (sexual) to 94.6% (emotional). Adolescents who reported child abuse, those living in violent areas, and those who consumed alcohol more frequently had a higher prevalence of DV. Manuscripts 2 and 3 used latent classes analysis (LCA) to identify the DV patterns (manuscript 2) and the VAC pattern (manuscript 3) based on the aggregation of individuals into classes, characterized according to the probability of endorsement to the different items from the CADRI and CTQ instruments. In addition to identifying these patterns, we sought to use the estimated classes in causal models, assessing the effects of the VAC dimensions for the DV patterns (manuscript 2) and the VAC classes for adolescents' mental health (manuscript 3). In manuscript 2, three latent classes of DV were identified among girls and boys. Childhood sexual abuse increased the chance of belonging to the most severe class of DV victimization among girls (OR = 5.72; 95% CI = 2.51-13.06). Emotional (OR=5.97; 95% CI = 1.95-18.30) and physical (OR=3.16; 95% CI=1.07-9.34) abuse increased the chances of classifying boys in the most severe class of DV perpetration. The LCA of manuscript 3 also identified three classes of VAC, both in girls and boys. Despite several similarities between the classes of the two sexes, girls suffered more with sexual abuse and boys with corporal punishment (physical punishment). Belonging to the most severe class of VAC increased the GHQ-12 scores by 2 to 3 points compared to the milder classes of violence. Based on these results and with the discussions brought by the three manuscripts, it is expected that this thesis has contributed both to the thematic discussions of violence and presented some methodological advances in the field of epidemiological analysis. Regarding the first aspect, once again, it is evident that violence between parents and children is a public health problem due to its high frequency and direct and specific relationship with violence in adolescents' dating. Debates on the relationship between violence and gender have expanded, as both the prevalence and patterns of violence differ between boys and girls since childhood; patterns of violence were identified that indicate that experiencing different types of abuse is the most frequent situation among children and adolescents, and it was noticed that the repercussions of violence against children on the mental health of adolescents depend on the pattern of co-occurrence of different forms of child victimization. Regarding methodological advances, the thesis is innovative as it proposes the use of LCA to characterize VAC and DV for the first time in Brazil. Furthermore, the thesis advances by articulating the identification of patterns of violence via the analysis of latent classes with their risk factors and consequences, expanding the possibilities of inference from the models.

Abstract Introduction In Mexico, alcohol consumption is the main problem related to substance use among university students. Objective To analyze emerging alcohol consumption patterns in students at a public university through the administration of an online survey. Method This is a cross-sectional, survey-based study. Participants included 3,888 students from a large university in Mexico City, to whom the alcohol and sociodemographic data section of the Cuestionario de Estudiantes 2014 was electronically administered in August-September 2018 and 2019. Latent Class Analysis was applied to the data obtained. During the research, the principles, norms, and ethical precepts of research on human beings were observed. Results The relevant variables observed were length of exposure to alcohol, excess alcohol consumption, consumption on a typical day and alcohol-related consequences, which were used to create a model with four groups: teetotalers and early drinkers without consequences, risky drinkers with consequences, experienced risky drinkers without consequences and habitual drinkers with consequences. 36.7% of the sample were classified into groups with consequences and a high likelihood of excess consumption. Discussion and conclusion Lengthy exposure to alcohol influences measures of frequency and intensity of consumption in relation to the number of consequences suffered. This latent class model can guide the design and priority of universal, selective, or suggested preventive interventions.
Resumen Introducción En México, el consumo de alcohol es el principal problema relacionado con el uso de sustancias entre estudiantes universitarios. Objetivo Analizar los patrones emergentes de consumo de alcohol en estudiantes de una universidad pública por medio de la aplicación de una encuesta en línea. Método Es un estudio transversal por encuesta en que participaron 3,888 estudiantes de nivel medio superior y superior de una universidad pública de gran tamaño en la Ciudad de México, a quienes se les aplicó, vía electrónica, la sección de alcohol y datos sociodemográficos del Cuestionario Estudiantil 2014, en los meses de agosto-septiembre de 2018 y 2019. Se aplicó un Análisis de Clases Latentes a los datos obtenidos. Durante la investigación se observaron los principios, normas y preceptos éticos de la investigación con seres humanos. Resultados Las variables observadas relevantes fueron: tiempo de exposición a la sustancia, consumo excesivo de alcohol, consumo en un día típico y consecuencias asociadas al consumo, con las cuales se integró un modelo de cuatro clases: abstemios y bebedores iniciales sin consecuencias, bebedores riesgosos con consecuencias, bebedores riesgosos experimentados sin consecuencias y bebedores habituales con consecuencias. El 36,7% de la muestra se agrupó en las clases con consecuencias y una alta probabilidad de consumo excesivo. Discusión y conclusión El tiempo de exposición a la sustancia articula las medidas de frecuencia e intensidad del consumo en relación con el número de consecuencias sufridas. Este modelo de clases latentes puede guiar el diseño y prioridad de intervenciones preventivas universales, selectivas o indicadas.
