Latent Class Analysis and Influencing Factors of Cognitive Ability Level of Hospice Care Nursing Students / 昆明医科大学学报

Objective To explore the different latent class and characteristics of the cognitive ability level of undergraduate nursing students in hospice care based on the individual-centered perspective,and analyze its influencing factors to provide the reference for the formulation of targeted nursing education.Methods Nursing students in a medical university in Yunnan Province were selected from March 2023 to June 2023.The general data questionnaire and hospice care knowledge questionnaire were used to conduct a cross-sectional survey.SPSS and Mplus were used for the data analysis.Results Three latent class of hospice care cognitive ability were identified,which were named as hospice care high cognitive ability group,general cognitive ability group,and low cognitive ability group,accounting for 28.74%,57.29%,and 13.97%,respectively;Nursing students'gender,nationality,place of residence,earning and practice experience of hospice care(whether they had the contact with end-stage cancer patients,whether they had received the hospice care related training),and whether they were willing to engage in the hospice care related work were the influencing factors of different potential categories of cognitive ability of hospice care among nursing students(P<0.05).Conclusion There are three latent class of hospice care cognitive ability of nursing students.Male minority nursing students who have not been exposed to end-stage cancer patients and have not received the hospice care-related training,are unwilling to engage in the hospice care-related work.Male ethnic minority nursing students residing in rural areas have the weaker cognitive levels of hospice care.Scholars in the future can formulate targeted training strategies according to different latent class of hospice care cognitive ability to improve nursing students'hospice care cognitive ability and reserve talents for hospice care teams.

Relationship between severity of preoperative brain injury and postoperative delirium in elderly patients: a latent class analysis of markers of brain injury / 中华麻醉学杂志

Objective:To evaluate the relationship between the severity of preoperative brain injury and postoperative delirium (POD) in elderly patients using latent class analysis based on markers of brain injury.Methods:One hundred and thirty-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 65-84 yr, with a body mass index of 18-28 kg/m 2, scheduled for elective unilateral total hip arthroplasty in our hospital, were selected. Cognitive function was assessed using the Mini-Mental State Examination before surgery. Arterial blood samples were collected before anesthesia to measure the plasma concentrations of brain-derived neurotrophic factor, inducible nitric oxide synthase, prostaglandin E2, central nervous system-specific protein (S100β), glial fibrillary acidic protein, neurofilament light chain, matrix metalloproteinase-9, fibroblast growth factor 23, complement 3, complement 3a, complement 5a and irisin using enzyme-linked immunosorbent assay. POD was evaluated using the Confusion Assessment Method within 3 days after operation, and the patients were divided into POD group and non-POD group. The patients were divided into different injury severity subtypes based on the levels of brain injury markers using latent class analysis, and logistic multivariate regression was used to analyze the independent risk factors for POD. Results:Compared with non-POD group, the concentrations of neurofilament light chain, glial fibrillary acidic protein, S100β and prostaglandin E2 were significantly different in POD group ( P<0.05). Using these four brain injury markers for latent class analysis, patients were divided into a high severity of brain injury group (91.51%) and a low severity of brain injury group (8.49%). The results of logistic multivariate regression analysis showed that subtypes of brain injury ( OR=8.31, 95% confidence interval [ CI] 1.77-38.90, P=0.007), age ( OR=1.14, 95% CI 1.03-1.24, P=0.007), and plasma irisin concentrations ( OR=0.99, 95% CI 0.98-0.99, P=0.027) were independent risk factors for POD. Conclusions:Higher severity of preoperative brain injury is an independent risk factor for POD in elderly patients.

Relationship between lifestyle and mental health in preschool children / 中国儿童保健杂志

【Objective】 To explore lifestyle patterns among Chinese preschool school children by latent class analysis, and to analyze its associations with behavior problems from person-centered perspective, in order to provide theoretical reference for improving children′s mental health. 【Methods】 A questionnaire survey was conducted among parents of children aged 3 - 6 years old in five kindergartens in Xuzhou city by cluster sampling from April to May 2021.The survey content included the demographic characteristics, rearing environment, life behaviors and behavior problems, which was measured by Strengths and Difficulties Questionnaire(SDQ). Latent class analysis was used to explore latent lifestyle patterns.Unadjusted and adjusted Logistic regression analysis was used to test the associations between latent lifestyle patterns and behavior problems. 【Results】 The sample size was 1 190, including 618 (51.9%) boys.Latent class analysis for 7 life behaviors showed that three latent class model was the best one: low-risk group (206, 17.3%), medium-risk group (721, 60.6%) and high-risk group (263, 22.1%).After controlling demographic factors, adjusted Logistic regression model showed that compared to low-risk group, children in high-risk group had more risks of developing hyperactivity (OR=2.129, 95%CI: 1.230 - 3.685), peer problems (OR=2.051, 95%CI: 1.316 - 3.197), and total difficulties (OR=2.081, 95%CI: 1.290 - 3.356). 【Conclusions】 Improper dietary balance and irrational structure of daily activities substantially escalate the risk of emotional and behavioral issues in preschool-age children.Helping preschool children form a healthy lifestyle pattern is conducive to preventing behavioral problems.

Analysis of latent classes and predictive factors of health behavior among stroke patients / 中华行为医学与脑科学杂志

Objective:To explore the latent classes of health behavior and explore the predictive factors among stroke patients.Methods:A total of 1 250 participants were recruited using cluster random sampling in September 2022. The general information, the modified Rankin scale(mRS), stroke prevention knowledge questionnaire(SPKQ), health behavior scale for stroke patients (HBS-SP), and short form-health belief model scale (SF-HBMS) were administered in the cross-sectional survey. Mplus 8.3 software was used to conduct a latent class analysis (LCA) on the health behavior of stroke patients, and SPSS 27.0 software was used to carry out multinomial Logistic regression to analyze the predictive factors of different latent classes of health behavior of stroke patients.Results:The health behavior of stroke patients obtained three latent classes: low health behaviors-lack of health responsibility group (66.9%, n=794), moderate health behaviors-poor compliance group (11.9%, n=141), and good health behaviors-insufficient exercise group (21.2%, n=251). Compared with good health behaviors-insufficient exercise group, stroke patients with shorter duration education time ( B=-0.589, OR=0.555, P=0.036), hemorrhagic stroke ( B=0.082, OR=1.086, P<0.001), fewer comorbidities ( B=-0.022, OR=0.978, P=0.026), higher mRS score ( B=-0.046, OR=1.047, P=0.004), lower SPKQ score ( B=-0.055, OR=0.947, P=0.016), and lower SF-HBMS score ( B=-0.085, OR=0.919, P<0.001) were more likely to be included in moderate health behaviors-poor compliance group. However, stroke patients with shorter duration education time ( B=-0.026, OR=0.974, P=0.003), rural areas dwelling ( B=0.800, OR=2.225, P=0.004), fewer comorbidities ( B=-0.056, OR=0.945, P<0.001), lower SPKQ score ( B=-0.101, OR=0.904, P<0.001), and lower SF-HBMS score ( B=-0.071, OR=0.931, P<0.001) were more likely to be included in low health behaviors-lack of health responsibility group. Conclusion:The health behavior of stroke patients has three latent classes. A targeted intervention should be carried out according to the characteristics of different classes to improve their health behavior levels.

Objective@#To analyze the association between latent class of health-risk behaviors and depressive symptoms among middle school students, so as to provide the evidence for the prevention and intervention of depressive symptoms among middle school students.@*Methods@#Students in two junior high schools, two senior high schools and one vocational high school in Yinzhou District, Ningbo City, Zhejiang Province, were selected using a stratified multi-stage cluster sampling method. Demography and health-risk behaviors were collected using questionnaire surveys, depressive symptoms were investigated using the Center for Epidemiological Studies Depression-10 Scale, and latent class analysis was conducted for health-risk behaviors. The association between different latent classes and depressive symptoms was analyzed using a multivariable logistic regression model.@*Results@#A total of 1 247 students were surveyed, including 641 boys (51.40%) and 606 girls (48.60%). There were 452 junior high school students (36.25%), 532 high school students (42.66%) and 263 vocational high school students (21.09%). Latent class analysis showed that health-risk behaviors in students were classified into three groups, namely healthy behavior group (52.93%), poor diet group (39.94%) and high-risk behavior group (7.14%), and the detection rates of depressive symptoms were 7.12%, 18.88% and 52.81%, respectively, with a statistically significant difference between groups (P<0.05). Multivariable logistic regression analysis showed that after adjusting for age, gender, native place, only child and living on campus, the poor diet group (OR=3.107, 95%CI: 2.086-4.627) and high-risk behavior group (OR=15.401, 95%CI: 9.031-26.262) had higher risks of depressive symptoms compared with the healthy behavior group.@*Conclusion@#Having high-risk behaviors and poor diet may increase the risk of developing depressive symptoms among middle school students.

Discrimination based on gender identity against transgender women and travestis in Brazil: a latent class analysis and associated factors / Discriminação por identidade de gênero entre mulheres trans e travestis no Brasil: uma análise de classes latentes e fatores associados

ABSTRACT Objective To identify groups of transgender women and travestis (TGW) with specific patterns of gender-based discrimination (GBD) and analyze the factors associated with GBD. Methods A cross-sectional study was conducted with TGW recruited through respondent-driven sampling in five Brazilian cities (2019-2021). Latent class analysis was used to characterize GBD (low, medium, and high) using 14 observable variables. Descriptive analysis was performed, and associations between predictor variables and GBD were estimated by adjusted odds ratios (aOR) using ordinal logistic regression. Results Out of a total of 1,317 TGW, 906 (68.8%) answered questions about GBD. Most were under 34 years old, single, and had a Brown race/skin color. GBD was classified as "low," "medium," and "high," with estimates of 41.7, 44.5, and 13.8%, respectively. Variables positively associated with higher intensity of GBD included living in Manaus compared to São Paulo, being ≤34 years old compared to >34, being homeless compared to living in one's own house or rented apartment, not having legally changed one's name compared to those who had, and reporting physical or sexual violence compared to those who did not report. Variables negatively associated with higher intensity of GBD included having a Brown or Asian race/skin color compared to White and a monthly income ≥1 minimum wage compared to ³1. Conclusion A high proportion of GBD was observed in Brazilian TGW, with this outcome associated with more vulnerable sociodemographic characteristics and a history of violence.

RESUMO Objetivo Identificar grupos de mulheres trans e travestis (MTT) com padrões específicos de discriminação por identidade de gênero (DIG) e analisar os fatores associados à DIG. Métodos Estudo transversal com MTT recrutadas por respondent-driven sampling em cinco capitais brasileiras (2019-2021). Análise de classes latentes foi usada para caracterizar a DIG (em baixa, média e alta) usando 14 variáveis observáveis. Análise descritiva foi realizada e as associações entre variáveis preditoras e DIG foram estimadas por odds ratio ajustados (ORaj), usando regressão logística ordinal. Resultados Do total de 1.317 MTT, 906 (68,8%) responderam perguntas sobre DIG. A maioria apresentava idade ≤34 anos, solteiras e com raça/cor de pele parda. DIG foi classificada em "baixa", "média" e "alta", com estimativas de 41,7, 44,5, 13,8%, respectivamente. As variáveis positivamente associadas à maior intensidade de DIG foram: morar em Manaus em comparação com São Paulo; possuir idade £34 anos em comparação com idade >34; estar em situação de rua em comparação com quem mora em casa ou apartamento próprio ou alugado; não ter retificado o nome em documento em comparação com quem retificou; e relato de violência física ou sexual em comparação com quem não relatou. As variáveis negativamente associadas à maior intensidade de DIG foram: raça/cor de pele parda ou amarela em comparação com branca; e renda média mensal <1 salário mínimo em comparação com ≥1 salários. Conclusão Observaram-se alta proporção de DIG em MTT brasileiras e associação desse desfecho com características sociodemográficas mais vulneráveis e histórico de violência.

The brief measure of preoperative emotional stress screens preoperative maladaptive psychological features and predicts postoperative opioid use: an observational study

Abstract Background: The Brief Measure of Preoperative Emotional Stress (B-MEPS) is a suitable screening tool for Preoperative Emotional Stress (PES). However, personalized decision-making demands practical interpretation of the refined version of B-MEPS. Thus, we propose and validate cut-off points on the B-MEPS to classify PES. Also, we assessed if the cut-off points screened preoperative maladaptive psychological features and predicted postoperative opioid use. Methods: This observational study comprises samples of two other primary studies, with 1009 and 233 individuals, respectively. The latent class analysis derived emotional stress subgroups using B-MEPS items. We compared membership with the B-MEPS score through the Youden index. Concurrent criterion validity of the cut-off points was performed with the severity of preoperative depressive symptoms, pain catastrophizing, central sensitization, and sleep quality. Predictive criterion validity was performed with opioid use after surgery. Results: We chose a model with three classes labeled mild, moderate, and severe. The Youden index points −0.1663 and 0.7614 of the B-MEPS score classify individuals, in the severe class, with a sensitivity of 85.7% (80.1%-90.3%) and specificity of 93.5% (91.5-95.1%). The cut-off points of the B-MEPS score have satisfactory concurrent and predictive criterion validity. Conclusions: These findings showed that the preoperative emotional stress index on the B-MEPS offers suitable sensitivity and specificity for discriminating the severity of preoperative psychological stress. They provide a simple tool to identify patients prone to severe PES related to maladaptive psychological features, which might influence the perception of pain and analgesic opioid use in the postoperative period.

Multimorbidity patterns and associated factors in a megacity: a cross-sectional study

ABSTRACT OBJECTIVE To identify empirical patterns of multimorbidity and quantify their associations with socioeconomic, behavioral characteristics, and health outcomes in the megacity of São Paulo. METHODS This was a cross-sectional study conducted through household interviews with residents aged 20 years or older in urban areas (n = 3,184). Latent class analysis was used to identify patterns among the co-existence of 22 health conditions. Age-adjusted prevalence ratios were estimated using Poisson regression. RESULTS The analysis of latent classes showed 4 patterns of multimorbidity, whereas 58.6% of individuals were classified in the low disease probability group, followed by participants presenting cardiovascular conditions (15.9%), respiratory conditions (12.8%), and rheumatic, musculoskeletal, and emotional conditions (12.8%). Older individuals, with lower schooling and lower household income, presented higher multimorbidity prevalence in cardiovascular, respiratory, rheumatic, musculoskeletal, and emotional conditions patterns compared with the low disease probability pattern. CONCLUSION The results showed four distinct patterns of multimorbidity in the megacity population, and these patterns are clinically recognizable and theoretically plausible. The identification of trends between patterns would make it feasible to estimate the magnitude of the challenge for the organization of health care policies.

Association between HIV Perceived Risk and Intimate Partner Violence among Women / Asociación entre Percepción de Riesgo de VIH y Violencia de Pareja en Mujeres

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.

Lifestyle behaviors and associated factors among individuals with diabetes in Brazil: a latent class analysis approach / Comportamentos de estilo de vida e fatores associados entre indivíduos portadores de diabetes no Brasil: uma abordagem com análise de classes latentes

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.

Patrones de victimización por violencia en el noviazgo y consumo de alcohol en adolescentes estudiantes del sur de Jalisco, México / Patterns of dating violence victimization and alcohol consumption among adolescent students from southern Jalisco, Mexico

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.

Perception of college-going girls towards corneal donation in North India: A latent class analysis study

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.

The latent class of resourcefulness among primary caregivers of stroke patients / 中国实用护理杂志

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.

A latent class analysis of feeding practices among preschoolers’ parents and its correlations with parental depression status / 中华行为医学与脑科学杂志

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.

Relationship of latent classes of emotional behavior of children with mental disorders with sense of parenting competence and psychological distress of parents / 中华行为医学与脑科学杂志

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.

Latent profile analysis of multiple symptom distress in children and adolescents with cancer and its effect on their physical activity / 上海交通大学学报（医学版）

Objective·To describe the level of multiple symptom distress and physical activity in children and adolescents with cancer,analyze symptom distress profiles,and explicit the relationship between latent profiles and physical activity.Methods·From November 2021 to March 2023,the convenient sample method was used to recruit children and adolescents with cancer aged 10-18 years old,who had been treated for more than 1 month in the Departments of Hematology/Oncology,Shanghai Children's Medical Center and Xin Hua Hospital,Shanghai Jiao Tong University School of Medicine.The questionnaires,including General Information Questionnaire,Memorial Symptom Assessment Scale 10-18(MSAS 10-18)and Modified Chinese Version of Children's Leisure Time Activities Study Survey(CLASS-C),were used.Latent profile analysis was used to identify whether the level of multiple symptom distress in children and adolescents with cancer was population heterogeneity and its explicit characteristics.Whether there were differences in physical activity levels among different profiles of symptom distress was also analyzed.Results· A total of 165 valid questionnaires were collected,with an effective response rate of 91.7％.The symptom distress scores of the top five occurrence rates of symptoms in children and adolescents with cancer were lack of energy with a median of 1(1,2)point,nausea 1(1,2)point,lack of appetite 2(2,3)points,sweat 1(1,2)point,and pain 1(1,2)point.The physical activity level of the patients was mainly light,with a median of 2 530.00(1 577.50,3 721.00)min/week,and moderate to vigorous physical activity was relatively lower[70.00(10.00,197.50)min/week].The patients with cancer could be divided into two latent profiles:"high fatigue-high nausea-high hair loss-high sleepy"and"high fatigue-low nausea-low vomiting-low sleepy",which were named as high symptom distress(n=47,30.6％)and low symptom distress(n=l 18,69.4％)separately.Multivariate Logistic regression analysis showed that patients with acute lymphoblastic leukemia were more likely to be classified as high symptom distress group,and outpatients in the latest hospital visit were more likely to classified as low symptom distress group(both P＜0.05).In addition,patients with high symptom distress had a higher level of light physical activity(P＜0.05),and had a lower level of moderate to vigorous physical activity,but the difference was not statistically significant.Conclusion·There is population heterogeneity in the multiple symptom distress in children and adolescents with cancer.Disease type(acute leukemia)and the way of the latest hospital visit(through outpatient department)are the predictors of symptoms profiles of patients with cancer.Patients who experience high symptom distress have higher level of light physical activity,and perhaps lower level of moderate to vigorous physical activity.

Characteristic and influencing factors of temperature trajectories of patients undergoing laparoscopic hysterectomy / 中国实用护理杂志

Objective:To explore the characteristic and influencing factors of temperature trajectories of patients undergoing laparoscopic hysterectomy, to provide reference for intraoperative temperature management.Methods:Using retrospective analysis methods, the patients undergoing laparoscopic hysterectomy hospitalized in Zhoushan Branch of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2019 to December 2022 were collected as the research subjects by convenient sampling method. The patient′s body temperature data at the beginning of the surgery, 30 minutes, 60 minutes, 90 minutes, 120 minutes during the surgery, and at the end of the surgery were recorded. The latent class growth model was used to identify the potential trajectory category. Multiple Logistic regression analysis was used to analyze the influencing factors of trajectory category.Results:The intraoperative temperature changes of patients could be divided into three trajectories: 30.0% (45/150) in the normal temperature group, 38.7% (58/150) in the hypothermia resuscitation group, and 31.3% (47/150) in the hypothermia non resuscitation group. There was a statistically significant difference in the three potential categories of intraoperative body temperature trajectory among patients in indicators such as age, BMI, intraoperative infusion volume, surgical time, and anesthesia time ( F values were 3.39-30.01, all P<0.05). Multiple Logistic regression analysis showed that BMI, intraoperative infusion volume, surgical time, and anesthesia time were the prediction factors for temperature trajectory of patients undergoing laparoscopic hysterectomy (all P<0.01). Conclusions:The temperature in patients undergoing laparoscopic hysterectomy demonstrates three different trajectories, medical staff should implement targeted interventions based on the different trajectory characteristics of temperature.

Latent classes and influencing factors of vicarious posttraumatic growth among emergency nurses / 中国实用护理杂志

Objective:To investigate the latent classes and influencing factors of vicarious posttraumatic growth among emergency nurses.Methods:Convenience sampling method was used to select the 498 emergency nurses of 20 public general hospitals in Anhui province as the survey objects. The general information questionnaire and Posttraumatic Growth Inventory were used to investigate. Latent class analysis was used to classify vicarious posttraumatic growth of emergency nurses, and the influencing factors of latent classes were analyzed by binary logistic regression.Results:There were two latent classes of vicarious posttraumatic growth of emergency nurses including high growth-high fluctuation group (24.1%, 120/498) and low growth group (75.9%, 378/498). Binary logistic regression analysis showed that professional title, average monthly income and self-rated health status were the factors influencing the latent classes (all P<0.05). Conclusions:There are obvious classification characteristics of vicarious posttraumatic growth among emergency nurses. Nursing managers should formulate and implement targeted intervention measures according to the classification characteristics and influencing factors to improve their vicarious posttraumatic growth level.

Latent class analysis of psychological distress among older adults with multiple chronic conditions in communities / 中华护理杂志

Objective To explore latent class of psychological distress among the elderly with multiple chronic conditions in the community and to analyze differences in demographic and alexithymia characteristics across class.Methods A total of 685 urban and rural elderly with chronic disease co-morbidities in 6 prefecture-level cities in Jiangsu Province were selected for the study using the General Information Questionnaire,the Depression Anxiety and Stress Scales-21,and the Toronto Alexithymia scale from November 2022 to March 2023 using a convenience sampling method.Results A total of 662 older adults with multiple chronic conditions were finally investigated with a total psychological distress score 30.00(16.00,52.00).Psychological distress manifested itself in 4 different potential categories named"stress-depressive"(19.9%),"low distress"(26.0%),"stress-anxiety"(23.4%),and"overall high distress"(30.7%).The comparison of the different psychological distress categories with respect to age group,marital status,residential status,financial stress of illness,acute events within 1 year,and self-perceived health status showed statistically significant differences(P＜0.05).The comparison of alexithymia scores for the 4 potential categories showed statistically significant differences(F=136.544,P＜0.001).Conclusion Psychological distress in older adults with multiple chronic diseases has distinct categorical features,and alexithymia varies across different categories of psychological distress.Healthcare professionals can adopt targeted interventions according to different categories of chronic disease co-morbidities in order to reduce their psychological distress,and at the same time they should focus on older adults with the alexithymia of"stress-depressive"and"overall high distress".

Analysis on the characteristics and patterns of work-related musculoskeletal disorders among sonographers in Guangdong Province / 中国职业医学

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.
