Its consequences include multifaceted outcomes from complex interactions of sociocultural, environmental, and individual lifestyle factors. This research explores the impacts of socio-cultural environment and lifestyle factors on the psychological health of university students in Dhaka, Bangladesh. Methods: A 15-month follow-up was carried out among 1140 university students from April 2016 to November 2017. Data were collected by using a pre-developed questionnaire, consisting of socio-demographic information, comprehensive lifestyle information, and psychological health information including a nine-item scale, the Patient Health Questionnaire-9 (PHQ-9) for assessing the level of depression, and a 7-item scale, the Generalized Anxiety Disorder-7 (GAD-7) for assessing the level of anxiety. The collected data were analyzed by using the Statistical Package for Social Sciences (SPSS) software, version 22. Results: With time, there was a 22.5% increase in the prevalence of provisional depression and a 27.1% increase in the prevalence of anxiety. In terms of demographic factors, findings revealed that students dissatisfied with university culture were significantly more likely to experience depression (B = 5.13, p<0.01, β=0.33) and anxiety (B = 4.69, p<0.01, β=0.34). 'Being female', 'being students of social sciences faculty', 'dissatisfaction with current education, financial condition and future career' were found to be significant predictors of students' psychological disorders. In terms of lifestyle factors, participants with high and excessive recreational screen time were significantly more vulnerable to depression (B = 1.25, p<0.01, β=0.097 and B = 1.75, p<0.01, β=0.12) and anxiety (B = 0.86, p = 0.02, β=0.08 and B = 1.22, p<0.01, β=0.096). Additionally, 'weekly physical inactivity', 'dissatisfaction with daily sleep', 'short and long sleep duration', 'low and high daily meal intake frequency' and 'alcohol consumption' were inextricably linked with students' depression and anxiety. Conclusion: The prevalence of provisional as well as major depressive and anxiety disorders among university students in Bangladesh is significantly high and augmented in nature. This study provides significant information about the adverse impacts of university socio-cultural environment and students' lifestyle factors on their psychological health conditions.

Household air pollution (HAP) is one of the most important global environmental and public health... more Household air pollution (HAP) is one of the most important global environmental and public health issues. As a result of changes in air composition due to rapid industrialization and urbanization, air quality is deteriorating and outdoor pollution is increasing daily. Simultaneously, poor ventilation, microbial growth, tobacco smoke, solid fuel use, and different toxic chemicals are causing deterioration in household air quality, which contributes significantly to the global burden of disease. This paper reviews the available literature to examine the impact of HAP on human health, comprehensively identifies the sources of HAP, and synthesize management approaches to reducing the severity of HAP. The English language databases PubMed, Google Scholar, Web of Science, and Science Direct were searched using the key terms: HAP, particulate matter, health risks, public health, pollutant sources, burden of diseases, and management approach. Bibliographies of all relevant articles were also screened to find further useful articles. This review addresses all possible sources of HAP that are categorized as biological or chemical (organic and inorganic) and are associated with grave public health threats, such as lung function reduction, respiratory illness, asthma, pneumonia, tuberculosis, eye diseases, pregnancy complications, cardiovascular diseases, and cancer. Suggested approaches, including compliance with international guidelines and regulatory frameworks, pollutant source reduction methods, and fulfillment of international environmental laws, conventions, agreements, protocols, and treaties, can be effectively adopted to mitigate household air pollutants, reduce the global burden of disease, and promote household environments that support better human health. The sources of HAP and its health impacts should be considered in the development of future policies concerning reduction in all household air pollutants worldwide. Therefore, this review establishes the groundwork for future studies assessing the effectiveness of strategies aimed at creating sound household environments to promote better human health.

Methods: This cross-sectional study was conducted in the Out Patient Department (OPD) of BIRDEM, Bangladesh. A group of 977 subjects were randomly selected and followed up. Diabetes was diagnosed following the WHO study group criteria. The level of PA was categorized into inactive/low (<150 min/ week) and moderate-to-vigorous (150 min/week). The WHO recommended Asian criteria was used to identify general obesity. Retinopathy was detected by fundal photography, CKD by serum creatinine and hypertension was diagnosed clinically. Univariate and multivariate analyses were used to assess the associations of PA with diabetes related complications. Results: Out of the 977 subjects investigated, 468 were male and 509 were female (mean ± SD of age, 56 ± 8 years). In the study subjects, 74% were either inactive or in low PA and of them 65.1% were overweight/obese. Analysis showed that inactive/low PA was associated with all the three diabetes related complications (p < 0.001)ehypertension, retinopathy, and nephropathy. Multivariate analysis showed that inactive/low level of PA was strongly associated with complications like retinopathy (p < 0.001) and hypertension (p ¼ 0.01) in the female patients. It was also found to be highly associated with retinopathy (p < 0.001) among the male patients. Conclusion: A large number of urban Bangladeshi population are involved only in low PA or remain inactive themselves, which is leading to obesity and it seems to have a strong association with diabetes related complications in this population.

Since BMI is a common proxy measure used to evaluate nutritional status, the aim of this study was to investigate the BMI categories in school-aged children in Dhaka, Bangladesh. Methods: A cross sectional study of 155 children, aged 6-12 years was conducted at Jahangirnagar University School in Dhaka, Bangladesh. The data collection was performed by in-person interviews and semi-structured questionnaires. Descriptive statistics, χ2 test, Fisher's exact test, and One-Way ANOVA test were performed to compare the variables based on BMI percentiles. Data

Study design Cross-sectional survey. Methods Using the WHO STEPwise approach for NCDs, a cross-sectional study was conducted among 1,140 students. The collected data were analyzed using the Statistical Package for Social Sciences (SPSS) software, version 22. Results In all, 29.2% of the respondents (BMI ≥ 23.00 kg/m 2) were overweight and/or obese, and almost two-thirds (65%) of them did not take part in any physical activity (PA). A third (33.3%, p = 0.002) of male smokers reported health problems and it was found that environmental tobacco smoke (ETS) was significantly responsible for developing asthma (OR = 0.55; CI = 0.33– 0.93). Individual and family history of NCDs was statistically significant for obesity and asthma and considerably increased the odds ratio for heart disease. Conclusion This study shows that the number of students suffering from different types of NCDs is not negligible. Their lifestyle and family history of NCDs are responsible for this to a significant extent. Urgent initiatives should be taken to rein in the spread of NCDs among the youth of Bangladesh.

The aim of this study was to determine the prevalence of tobacco smoking and factors associated with the initiation of smoking among university students in Dhaka, Bangladesh.
Methods: A cross-sectional survey study was conducted with 264 students of Jahangirnagar University, Dhaka, Bangladesh in 2015. A standard, self-administered questionnaire consisting of questions on socio-demographic variables, tobacco smoking status, family and peer tobacco smoking history, attitudes and beliefs about tobacco smoking, as well as knowledge about the negative health consequences of tobacco smoking was administered to participants. Data were analyzed using logistic regression models, chi square, and Fisher exact tests.
Results: The overall prevalence of tobacco smoking was 60.2%, where males smoked at higher rates than females (68.81% and 19.56%, respectively). The influence of friends was the most significant reason for initiating tobacco smoking (OR: 0.862; CI: 0.810-0.917). Perception regarding tobacco smoking was significantly related to continuing tobacco use. Logistic regression models identified that smoking-related attitudes, potential health problems, and family members dying from cardiovascular disease and cancer were significantly associated with tobacco smoking.
Conclusion: The current tobacco smoking prevalence among university students in Bangladesh is over 60%. We suggest adopting WHO Framework Convention on Tobacco Control (FCTC) policies, especially for university students.
