Demographic characteristics are associated with children’s nutritional status: Findings from a pilot study on food insecure households in Simunjan district, Sarawak

@#Introduction: Food insecurity is a public health concern that may lead to malnutrition in children. The purpose of this study was to determine the relationship between demographic characteristics and food security level with nutritional status among children from food-insecure households in Simunjan District, Sarawak. Methods: This study involved a total of 171 mother-and-child pairs from two Maternal and Child Health Clinics (Simunjan and Gedong) using non-probability convenience sampling technique. Food insecurity status was determined using Radimer/Cornell Hunger Food Insecurity Instrument, while child’s weight and height were measured following standard procedures. Chi-squared test of independence and binary logistic regression were used during data analysis. Results: The prevalences for household food insecurity, individual food insecurity, and child hunger were 70.8%, 15.2%, and 14.0%, respectively. The main nutritional problems for children aged 24–59 months were underweight (17.9%) and stunting (17.9%), while for children aged 60–144 months were overweight and obesity (27.5%). Children of mothers over 34 years old (AOR=2.367; 95% CI: 1.085, 5.164), and those aged 60–144 months (AOR=3.619; 95% CI: 1.521, 8.613) had increased odds of being overweight or obese. Meanwhile, children of working mothers (AOR=6.526; 95% CI: 1.108, 38.449) were more likely to have a thinness problem than children of unemployed mothers. However, no association was found between the severity of food insecurity with children’s nutritional status. Conclusion: Malnutrition in children remains a public health concern in Simunjan District, and it is linked to mother’s age and employment status. An intervention programme is required to ameliorate the situation.

Demographic difference and influencing factors of motivations between whole blood and plasmapheresis donors: a comparative study / 中国输血杂志

【Objective】 To explore the difference of demographics and influencing factors of motivations between whole blood donors and plasmapheresis donors, so as to provide scientific reference for effective recruitment strategy. 【Methods】 A total of 200 whole blood donors from Guangyuan Blood Center and 200 plasmapheresis donors from Jiange Plasmapheresis Station were selected in August 2021 for on-site questionnaire survey using the method of cross-sectional survey. Statistical analysis was performed by chi-square test, univariate and multivariate logistic regression. 【Results】 There were significant differences in gender, age, occupation, education level and annual family income between whole blood donors and plasmapheresis donors (P<0.05). Males accounted for a large proportion of whole blood donors(124/196, 63.3%), whereas females accounted for a large proportion of plasmapheresis donors(117/198, 59.1%). There was little difference in the number of whole blood donors in different age groups, while the age of plasmapheresis donors was concentrated in 40~59 years old (167/198, 84.3%). In terms of occupation, civil servants (including public institutions) accounted the highest proportion in whole blood donors (41/196, 20.9%), and farmers accounted the highest proportion (152/198, 76.8%) in plasmapheresis donors. The number of whole blood donors increased with the education level, and donors with college/university and above degree accounted the largest proportion (80/196, 40.8%). Plasmapheresis donors with junior middle school education and college/university and above accounted the largest and smallest proportion (49.5% vs 4.5%). The annual family income of whole blood donors ranged from 30 000 to 80 000 yuan accounted the largest proportion (109/196, 55.6%), and the annual family income of plasmapheresis donors less than 30 000 yuan accounted the largest proportion (132/198, 66.7%). 【Conclusion】 There were significant statistical differences in gender, age, education level, occupation and annual family income between whole blood and plasmapheresis donors. Therefore, targeted recruitment strategies should be formulated.

Abuso sexual contra niños, niñas y adolescentes en Lima, Perú: una aproximación general a los patrones de personalidad, características sociodemográficas y el riesgo de violencia de los perpetradores / Sexual abuse of children and adolescents in Lima, Peru: an overview of personality patterns, socio-demographic characteristics and perpetrators' risk of violence / Abuso sexual de crianças e adolescentes em Lima, Peru: uma visão geral dos padrões de personalidade, características sociodemográficas e risco de violência por parte dos perpetradores

El riesgo de abuso sexual contra niños, niñas y adolescentes es un problema generalizado de salud pública y de derechos humanos que enfrentan todos los países. Este estudio tiene como objetivo determinar si las características sociodemográficas, el riesgo de violencia y los patrones de personalidad del perpetrador podrían predecir futuros episodios de abuso sexual infantil. Se realizó un estudio descriptivo transversal-correlacional en 32 personas privadas de la libertad (PPL) en un establecimiento penitenciario en Lima, Perú. Se utilizó la Ficha Sociodemográfica, el Inventario Clínico Multiaxial de Millon II y la Guía de Valoración del Riesgo de Violencia. Los participantes tenían una edad promedio de 41,5 ± 8,50 años; la mayoría mantenía una relación: convivientes (31,3%) y casados (21,9%); y tiene secundaria completa (56,3%). Los trastornos de personalidad predominantes fue-ron el dependiente (56,3%) y el compulsivo (84,4%). El 79% presentó riesgo moderado de violencia futura. Existen correlaciones modera-das y fuertes entre las variables de estudio; y la regresión logística multivariada reveló que la edad y algunos trastornos de personalidad podrían ser predictores del riesgo de abuso sexual infantil. Estos hallazgos son de utilidad para realizar perfiles delictivos de futuros agresores o reincidentes; y contribuyen al diseño de programas de prevención y tratamiento.

The risk of sexual abuse against children and adolescents is a widespread public health and human rights problem facing all countries. This study aims to determine whether socio-demographic characteristics, risk of violence and personality patterns of the perpetrator could predict future episodes of child sexual abuse. A descriptive cross-sectional-correlational study was conducted in 32 persons deprived of liberty (PPL) in a penitentiary establishment in Lima, Peru. The Sociodemographic Form, the Millon's Multiaxial Clinical Inventory II and the Violence Risk Assessment Guide were used. Participants had an average age of 41.5 ± 8.50 years; most were in a relationship: cohabiting (31.3%) and married (21.9%); and had completed secondary school (56.3%). The predominant personality disorders were dependent (56.3%) and compulsive (84.4%). Seventy-nine per cent were at moderate risk of future violence. There are moderate and strong correlations between the study variables; and multivariate logistic regression revealed that age and some personality disorders could be predictors of child sexual abuse risk. These findings are useful for criminal profiling of future offenders or repeat offenders; and contribute to the design of prevention and treatment programmes.

Knowledge, Attitude, and Practices Related to the SARS-CoV-2 Pandemic among Women Seeking Contraceptive Methods / Conhecimento, atitude e práticas relacionadas à pandemia de SARS-CoV-2 entre mulheres que buscam métodos anticoncepcionais

Abstract Objective To determine knowledge, attitude, and preventive (KAP) practices towards the SARS-CoV-2 (COVID-19) pandemic among women in reproductive age seeking to use copper or hormonal intrauterine devices (IUD/LNG-IUS). Methods We conducted a cross-sectional study in which we applied a questionnaire on 400 women about KAP practices on COVID-19 at the University of Campinas, Campinas, SP, Brazil, from May to August 2020. Results The mean (±SD) age of the women was 30.8±7.9 years, and 72.8% of them reported being pregnant at least once. Most women (95%) had heard or read about COVID-19, and their main sources of information were television (91%) and government websites (53%). However, 53% of the women had doubts about the veracity of the information accessed. Conclusion Women without a partner and with>12 years of schooling had more information about COVID-19 and on its impact on new pregnancy, and those from high socioeconomic status had a higher chance of maintaining physical distance. Safety, effectiveness, comfort, and absence of hormone in the contraceptive method (in the case of TCu380A IUD) were the main reasons for the participants to seek the service during the pandemic, and the possibility to stop menstrual bleeding was the main reason to choose the LNG-IUS.

Resumo Objetivo Determinar o conhecimento, atitude e práticas preventivas (CAP) em relação à pandemia de SARS-CoV-2 (Covid-19) entre mulheres em idade reprodutiva que buscam usar dispositivo intrauterino com cobre (DIU TCu 380) ou sistema intrauterino liberador de levonorgestrel (SIU-LNG). Métodos Foi realizado um estudo transversal e um questionário foi aplicado a 400 mulheres para conhecer o CAP sobre o COVID-19 na Universidade Estadual de Campinas, Campinas, SP, Brasil, no período de maio a agosto de 2020. Resultados A média (±DP) de idade das mulheres foi de 30,8±7,9 anos, e 72,8% delas relataram ter engravidado pelo menos uma vez. A maioria das mulheres (95%) tinha ouvido ou lido sobre a a Covid-19, e suas principais fontes de informação foram a televisão (91%) e sites do governo (53%). Porém, 53% das mulheres tinham dúvidas a respeito da veracidade das informações acessadas. Conclusão Mulheres sem companheiro e com mais de 12 anos de escolaridade tiveram mais informações sobre a COVID-19 e sobre o seu impacto em uma nova gravidez, e aquelas de nível socioeconômico alto tiveram maior chance de manter distância física. Segurança, eficácia, conforto e ausência de hormônio no método anticoncepcional (no caso do DIU TCu380A) foram os principais motivos para as participantes procurarem o serviço durante a pandemia, e a possibilidade de controlar o sangramento menstrual abundante foi o principal motivo para a escolha do SIU-LNG.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

Objective:To understand the demographic characteristics and treatment intention, treatment status and therapeutic effect of patients with skeletal fluorosis in Inner Mongolia Autonomous Region (reffered to as Inner Mongolia) in order to provide a basis for next step treatment program.Methods:From March to June 2020, a face-to-face questionnaire survey was conducted among 3 570 patients with skeletal fluorosis in 11 leagues (cities) of Inner Mongolia to understand their basic information, treatment intention, treatment status and therapeutic effect. Patients with skeletal fluorosis of different demographic characteristics were compared with each other in their treatment intention and treatment status, and the therapeutic effects of different drugs were compared by χ 2 test. Results:A total of 3570 patients with skeletal fluorosis were investigated. There were slightly more women than men with skeletal fluorosis (1.29 ∶ 1.00, 2 014/1 556). The ages were mainly from 40 to 79 years old (95.4%, 3 406/3 570). Mongols patients accounted for 36.0% (1 285/3 570). Patients with low education (primary school and below) accounted for 82.2% (2 935/3 570). Eighty-five per cent (3 035/3 570) of the patients had drug treatment intention and 37.1% (1 325/3 570) of the patients had drug treatment. Thirty-seven point five per cent (1 338/3 570) of the patients had surgery intention and surgery was performed in 0.2% (8/3 570) of the patients. Combination therapy (98.5%, 194/197) and chondroprotective agents alone (98.3%, 173/176) were more effective than anti-inflammatory and analgesic agents alone (84.2%, 48/57) in the treatment of skeletal fluorosis ( P < 0.05). Surgery was effective (8/8). Conclusions:Most of the patients with skeletal fluorosis are middle-aged and elderly, and the patients with skeletal fluorosis in Mongols account for a certain proportion. At present, all the patients with skeletal fluorosis who have the will to be treated have not been effectively treated, and the means of treatment is relatively single. It should be advocated to carry out various forms of treatment of skeletal fluorosis, so that patients could relieve symptoms, reduce pain and improve their quality of life.

Relações entre Burnout, traços de personalidade e variáveis sociodemográficas em trabalhadores brasileiros / Relationship between Burnout, personality traits and sociodemographic variables in Brazilian workers / Relaciones entre Burnout, rasgos de personalidad y variables sociodemográficas en trabajadores brasileños

O Burnout é caracterizado pela exaustão emocional, despersonalização e baixa realização no trabalho. O objetivo desta pesquisa foi investigar as relações entre variáveis sociodemográficas e traços de personalidade, segundo o modelo dos Cinco Grandes Fatores, no desfecho da síndrome. Os seguintes questionários: sociodemográfico, Inventário de Burnout no Trabalho e Marcadores Reduzidos de Personalidade foram respondidos, em plataforma on-line, por 343 profissionais brasileiros do setor de serviços (75,50% mulheres, n = 259) atuantes nas áreas da saúde, educação, serviços administrativos, segurança, bancários e atendimento ao público (e.g., telemarketing, call centers). Os resultados não apontam para relações estatisticamente significativas entre as variáveis sociodemográficas e o Burnout. Os traços de personalidade desempenharam relação preditiva mais relevante com os três fatores do Burnout, sendo o Neuroticismo o maior preditor. A partir dos dados, pode-se dizer que os recursos pessoais podem exercer um importante papel no desenvolvimento do Burnout, com especial atenção ao Neuroticismo. (AU)

Burnout is characterized by emotional exhaustion, depersonalization, and low personal accomplishment at work. The objective of this research was to investigate the relationship between sociodemographic variables and personality traits, according to the Big Five theory, in the outcome of the syndrome. The sociodemographic questionnaire, the Work Burnout Inventory and the Reduced Personality Markers were answered in an online platform by 343 Brazilian professionals from the service sector (75.50% women, n = 259), working in the areas of health, education, administrative services, security, banking and customer service (e.g. telemarketing, call centers). The results do not point to a statistically significant relationship between sociodemographic variables and burnout. Personality traits had a more predictive relationship with the three factors of burnout, which Neuroticism was the most important predictor. Personal resources, especially Neuroticism, can play an important role in the development of burnout. (AU)

The relationship between eating habits, socio-demographic characteristics and body mass index among undergraduate students from two selected universities, Tanzania

Background: Obesity is a current public health concern for both developed and developing countries. Previous studies have demonstrated that, university students exhibit poor eating habits and gain body weight more rapidly than the general population. The aim of this study was to investigate how socio-demographic characteristics and eating habits relate to body mass index (BMI) among undergraduate students from two selected universities in Morogoro region, Tanzania.Methods: This cross-sectional study was conducted at Mzumbe University and Jordan University College. Simple and cluster random sampling were used to select 200 students from the two universities. Questionnaire and Anthropometric measurements were used during data collection. One-way ANOVA and multiple linear regressions analysis were deployed with an assistance of computer software called SPSS.Results: The findings showed that each additional healthy eating habit score was insignificantly associated with 0.043 units decrease in BMI (p>0.05). This study found significant associations between mean BMI and female gender, age and place of origin (p<0.05). The results showed that each additional year of age was significantly associated with 0.495 units increase in BMI and female respondents were having 2.168 higher BMI than males. In addition, respondents from rural had significant lower BMI by 1.59 as compared to their urban counterparts.Conclusions: The study concluded that age, gender and place of origin relate with undergraduate student’s BMI significantly. The study recommend that public health planners and implementers should target age, gender, place of origin as well as eating habit during fighting for obesity among undergraduate students.

Determinantes sociodemográficos y personales del bienestar subjetivo y psicológico en población mexicana / Sociodemographic and personal factors determining subjective and psychological well-being in the Mexican population

RESUMEN En esta investigación el objetivo es analizar la capacidad predictiva de factores sociodemográficos y características personales sobre el bienestar subjetivo y psicológico en población mexicana. Los participantes fueron 976 adultos que cumplimentaron escalas de felicidad, satisfacción vital, emociones positivas y negativas, bienestar psicológico, los Cinco Grandes de personalidad, optimismo y autoestima. Los resultados indicaron que los factores sociodemográficos tenían un tamaño de efecto pequeño sobre las distintas dimensiones de bienestar subjetivo y psicológico. Los análisis de regresión múltiple mostraron que, tanto el bienestar subjetivo como el psicológico, eran explicados por alta extraversión, responsabilidad, autoestima y bajo neuroticismo. Estos resultados sugieren que, no solo los Cinco Grandes, sino la autoestima es un potente predictor de ambos tipos de bienestar en mayor medida que los factores sociodemográficos. Los descubrimientos son consistentes con los encontrados en otras culturas, aunque aparecen diferencias que son discutidas con relación a cómo abordarlas por parte de las autoridades mexicanas.

ABSTRACT The aim of this study is to determine the predictive capacity of socio-demographic and personal characteristics on subjective and psychological well-being in a Mexican population. A total of 976 Mexican adults completed scales of happiness, life satisfaction, positive and negative affect, psychological well-being, the Big Five personality traits test, as well as of optimism and self-esteem. The results showed that sociodemographic factors had a small effect size on the subjective and psychological well-being dimensions. Hierarchical multiple regression analyses demonstrated that subjective and psychological well-being was explained by a greater extraversion, conscientiousness, optimism, self-esteem, and less neuroticism. These results suggest that not only is the Big Five a more powerful predictor of both types of well-being than sociodemographic factors, but also that of self-esteem. The findings are consistent with those of other cultures, although there are differences, which are discussed in relation to how they should be approached by the Mexican authorities.
