Rapid unplanned urbanization is a common phenomenon in developing countries and the necessity for making an urban area sustainable livable one of major challenges today’s world. While timely identification factors contributing to rapid essential, uncovering core reasons behind this remains most challenging tasks. The Night Light Development Index (NLDI) can track monitor over time be used understanding optimizing use space at night due its availability accessibility. Previous research has only been conducted using VIIRS or DMP OLS satellite imagery calculate NLDI. However, temporal spatial resolution these types are quite poor require lot preprocessing. In research, complexities addressed by introducing modified NLDI, leveraging high-resolution nighttime from NASA’s Black Marble product suite population data Socioeconomic Data Applications Center (SEDAC). This study examines drivers Dhaka analyzing changes regional inequality, electrification patterns, GDP relation light, amidst significant posed countries. results indicate transformations Dhaka’s land cover change (ULCC), with substantial increases built-up areas correlating heightened economic activity/GDP, as evidenced NTL radiance patterns. Furthermore, NLDI effectively captures nuances development offering insights into disparities planning challenges. We find that income inequality value highest Biman Bandar (0.910), followed Pallabi (0.665), Turag (0.640), Khilkhet (0.587). These values disparity between affluent impoverished populations within regions.

This study aimed to estimate the association between urban physical disorder and alcohol consumption in Brazilian adolescents. The sample was composed of 2,384 adolescents, aged 12 17, resident capitals participants Study Cardiovascular Risk Adolescents (ERICA), a school-based cross-sectional undertaken 2013 2014. outcome variable alcoholic beverage characterized as having drunk an at least once previous 30 days. exposure measured according features 2010 Demographic Census. total effect indicators on among adolescents estimated using Poisson regression models with robust variance. Crude adjusted prevalence ratios (PR) were calculated 95% confidence intervals (95%CI) for each exposure, controlling possible confounding variables. living areas paved roads manholes presented higher (adjusted PR = 1.24, 95%CI: 1.02; 1.50 1.36, 1.01; 1.84, respectively). Conversely, presence wheelchair ramps open sewers associated lower 0.79, 0.62; 0.99 0.80, 0.66; 0.97, These findings suggest that contextual factors can influence Understanding these may aid development public health policies promote healthier environments.

Child undernutrition is associated with maternal mental health and other sociodemographic factors in low-income settings in Dhaka, Bangladesh

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(5), P. e0322507 - e0322507

Published: May 2, 2025

Background Maternal mental health and other underlying factors might affect a child’s nutritional status. This study assesses child undernutrition its associated characteristics, including maternal health, in low-income settings Dhaka, Bangladesh. Methods A community-based cross-sectional was conducted among 397 lactating mothers with children aged 6–23 months from Dhaka. Anthropometric measurements were taken following standard protocols, Z-scores for weight-for-age, height-for-age, BMI-for-age calculated. depression anxiety assessed using the Patient Health Questionnaire-9 Generalized Anxiety Disorder 7-Item Scale, respectively. The feeding index developed based on breastfeeding, dietary diversity, meal frequency. Multivariate logistic regression models explored relationship between risk factors. Results In regions of prevalence 31.9% stunting, 14.0% wasting, 24.1% underweight children. Approximately half experienced (55%) (50%). High levels increased odds stunted (AOR = 1.80, 95% CI 1.10–2.94, p < 0.05) wasted 2.70, 1.38–5.28, Similarly, linked to higher 1.77, 1.04–3.11, 0.05). Female had approximately twice stunting than boys 2.13, 1.32–3.44, 0.01). Younger age also doubled 1.97, 1.20–3.22, Low adherence 3.21, 1.99–5.16, 0.001) 4.20, 2.50–7.07, Children born almost as likely become 2.01, 1.01–4.03, compared those normal/overweight mothers. Conclusion adversely nutrition their Sociodemographic such sex, age, practices significantly contribute undernutrition. Policy initiatives should prioritize address these settings.
