Therefore, understanding risk factors of under-five mortality is essential to enhance the health and well-being of children. This research seeks to investigate associated factors of under-five mortality in Indonesia by using the 2017 Indonesia Demographic and Health Survey data. Methods: The multilevel zero-inflated and multilevel hurdle models are considered to handle unobserved heterogeneity that may occur at province level, and to model prevalence and risk of child death as a joint process, which are reported in terms of odds ratio (OR) and incidence ratio rate (IRR), respectively. Results: Lower number of household members (IRR = 0.803, 95% confidence interval [CI]: 0.784–0.823), older mother's age at first birth (IRR = 1.020, 95% CI: 1.007–1.032), higher number of children ever born (IRR = 1.491, 95% CI: 1.450–1.533), lower mother's education (IRR = 1.224, 95% CI: 1.013–1.479), and lower father's education (IRR = 1.232, 95% CI: 1.015–1.495) are significantly associated with higher total death numbers in children before the age of 5 years. Furthermore, the odds of no child death are significantly higher among mother who use a contraceptive method (OR = 11.088, 95% CI: 6.659–18.462) and among household in higher quantile wealth (OR = 1.133, 95% CI: 1.005–1.277). Conclusion: This evidence-based empirical highlights priority risk factors that might provide insight for policymakers, health professional, and the community in general to design appropriate intervention to help reduce the burden of under-five mortality in the country.","PeriodicalId":34783,"journal":{"name":"Asian Journal of Social Health and Behavior","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135550956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mitigating a crisis requires actions from individuals, family, friends, co-workers, various policymaking, and implementing agencies, media, and other agencies with whom people interact. In the COVID-19 situation, people individuals did not have a choice but to access essential services even with the risk of infection. Personal experiences also guide individuals' trust in various social groups and are responsible for taking individual action of protecting themselves in the pandemic. To what extent people trusted various social groups and observed appropriate behavior is investigated in this research. Methods: Responses were collected through a structured, web-based questionnaire where respondents self-reported their trust in various social agents and the extent to which they observed COVID-appropriate behavior. Respondents primarily belonged to the eastern part of India. Results: This study finds significant demographic differences in observing appropriate behavior leading to an identification of a vulnerable group. Second, trust in the inner group (family, friends, neighbors, and co-workers among others) is least important whereas trust in professionals and administrative institutions is the most important. Trust in the central government, media, and politicians among others is counterproductive to observing the appropriate behavior. Conclusion: People repose higher trust in professionals and administrative institutions in a crisis situation. Professional and administrative leadership helps in more effective crisis management leading to better behavioral compliance of the public. Any other leadership may be ineffective or counter-productive.","PeriodicalId":34783,"journal":{"name":"Asian Journal of Social Health and Behavior","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135550960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This descriptive-analytical study aimed to investigate the nutritional status of primary-school students in urban and rural areas of Abadan. Methods: Multi-stage stratified-cluster and simple random sampling was performed on urban and rural primary school students in Abadan with the demographic information, height, and weight of 1133 students measured. Furthermore, the indices of short stature for age (stunting), low weight for age (underweight), and low weight for height (wasting) in children were calculated and compared with the National Center for Health Statistics standard. Results: The results revealed that the average age of malnourished children was 9.56 years and the average age of normal children was 8.97 years. The malnutrition prevalence among primary school children of Abadan was 8%, and there was a poor correlation between factors such as sex (P = 0/8), place of residence (P = 0/4), plus school place (P = 0/9), and malnutrition, while there was a positive relationship between with the parents' level of education and malnutrition (P = 0/02). Thus, the most influential factor seems to be the parents' level of education and awareness. Conclusion: Steps can be taken to promote the social and cultural level of families and prevent malnutrition as well as improve the nutritional status of society through collaboration among various institutions, holding educational classes with the presence of education departments, and encouraging families. The household economic status is also one of the important factors in the implementation of these educational classes that must be considered.","PeriodicalId":34783,"journal":{"name":"Asian Journal of Social Health and Behavior","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42976575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, weight stigma may cause health and behavioral problems, such as a lack of motivation to exercise. Assessing weight stigma is thus essential. Both the Weight Self-Stigma Questionnaire (WSSQ) and the Perceived Weight Stigma Scale (PWSS) are valid and reliable instruments that have been used in several countries. However, WSSQ and PWSS have never been used in Indonesia. Therefore, this study aimed to translate and validate both WSSQ and PWSS in Indonesian for Indonesian young adults. Methods: Via an online survey with convenience sampling, Indonesian college students (n = 438) completed the Indonesian WSSQ, PWSS, and depression anxiety stress scale-21 (DASS-21), and provided their height and weight. Confirmatory factor analysis (CFA), Rasch analysis, internal consistency, and concurrent validity were used for data analysis. Results: The internal consistency was satisfactory for the WSSQ (α = 0.90 and ω = 0.93). One PWSS item did not fit well and was removed. The revised 9-item PWSS had satisfactory internal consistency (α = 0.82 and ω = 0.87). The CFA and Rasch results supported a two-factor structure for the WSSQ, and a one-factor structure for the PWSS. WSSQ and PWSS were significantly and positively correlated (r = 0.32; P < 0.001). Both WSSQ and PWSS were significantly and positively associated with the DASS-21 score (r = 0.18 to r = 0.48; all P < 0.001); WSSQ was significantly and positively associated with body mass index (BMI) (r = 0.17 to r = 0.50; all P < 0.01).

Methods: This cross-sectional study was conducted on 311 participants who were referred to the Health Centers of Arak, Iran, from November 2021 to December 2021. The participants were selected through multi-stage stratified random sampling. Data were collected using a questionnaire and consisted of sociodemographic data, mask-wearing behavior, and structures of HBM regarding mask wearing. Results: The participants' mean (standard deviation) age was 37.9 (12) years (ranging from 18–81). The rate of “always” wearing a face mask was 57.9%. Multiple regression analysis revealed that mask-wearing behavior was associated with demographic variables (age and gender), perceived severity (β = 0.17, P < 0.001), perceived benefits (β = 0.24, P < 0.001), and self-efficacy (β = 0.35, P < 0.001).

Methods: The research was performed using cross-sectional survey data from the 2019 Bangladesh Multiple Indicator Cluster Survey, and 61,242 household members were the sample for this study. The Chi-square test was applied for the bivariate analysis. A generalized linear mixed-effects model was used to identify the risk factors of practicing handwashing in both urban and rural areas of Bangladesh. Results: Only 65% of the country's households had access to handwashing facilities (place, water, and materials). While urban dwellers were more likely to wash their hands, rural dwellers were only 63% likely to do so. The level of education of household heads, wealth status, division, number of family members, sanitation facilities, and water source were the key factors associated with handwashing behavior. This study revealed that the odds were significantly lower among illiterate respondents compared to those with secondary and above-secondary education in both areas of Bangladesh, and a positive association was found between wealth status and handwashing behavior practiced in both urban and rural areas. In this study, the size of the family was statistically significant for both rural and urban areas of Bangladesh. Conclusion: Handwashing is the most prominent consideration for controlling COVID-19.
