Assessing Risk Factors of Diabetes Mellitus based on Rural-urban Residence in Bangladesh: Findings from Two Cross Sectional Surveys

Abstract

Background: Diabetes mellitus is a rising global health issue that causes a number of health complications and is becoming increasingly prevalent in countries with low and medium incomes. The objective of the study is to assess the changes of the prevalence and associated risk factors of diabetes mellitus in the middle-aged and elderly population in urban and rural areas of Bangladesh between the years 2011 and 2018. Methods: The relationship between the outcome variables and the covariates was evaluated using a chi-square test. In order to identify the risk factors strongly linked to diabetes mellitus, two distinct multivariate binary logistic regression models were utilized (one for urban and the other for rural areas). Results: In 2011 there were 8.3% of respondents who had diabetes, and 11% in 2017–18. Multivariate analysis of the determinants of diabetes status in relation to place of residence revealed a significant impact on age, education, wealth status, region, and survey year. Diabetes risk was lower in rural Bangladesh (OR = 0.87), according to the odds ratio. In terms of fixed effects, the risk of diabetes was significantly 2.34 times higher for rich households compared to poor urban households, whereas the risk was 1.98 times higher for rural households. Unemployed respondents had a higher risk of diabetes (OR = 1.33 for urban and OR = 1.31 for rural residences) than employed respondents. Both urban and rural respondents without hypertension were at less risk of diabetes than those with hypertension (OR = 0.73 for urban and OR = 0.77 for rural). Conclusion: A large proportion of the adult population in Bangladesh suffers from diabetes. Different health education programs are required to develop appropriate strategies, including proper weight control, physical activity, and healthier eating habits to prevent the prevalence of diabetes in Bangladesh.
