Potential association between allergenic food exposure and skin disease in Bangladesh: An application of principal component logistic regression (PCLR).

Background and Aim: Allergenic foods can trigger skin conditions, yet their impact in Bangladesh remains underexplored. This study aims to investigate the potential association between exposure to allergenic foods and the development of skin disease across Bangladesh. Methods: We conducted a cross-sectional survey with 970 respondents from the divisions of Dhaka, Sylhet, Rangpur, and Chattogram who self-reported skin disease triggered by food allergens. We analyzed the data using multiple response analysis and principal component logistic regression. Results: Approximately 64% of respondents had skin disease attributable to allergenic foods, with a relatively higher proportion among females (52%) than males (48%). Beef (67%), Brinjal (47.1%), Hilsa (45.8%), and Shrimp (23.7%) were the most frequently cited allergenic foods. Principal component logistic regression identified two highly significant principal components: the first representing Hilsa, Beef, and Brinjal (odds ratio = 2.256), and the sixth reflecting Corn (odds ratio = 1.342). Individuals who consumed foods with high loadings of the first principal component were 125.6% more likely to develop skin disease than nonconsumers, while those exposed to Corn had a 34.2% higher risk. Conclusion: The findings highlight prevalent allergenic foods in Bangladesh and their substantial impact on skin health, underscoring the need for dietary awareness and tailored interventions to mitigate allergic skin conditions in this population.

Under-five children's acute respiratory infection dropped significantly in Bangladesh: An evidence from Bangladesh demographic and health survey, 1996-2018.

AIM: This study aims to systematically identify and review the most significant risk factors and the trends that follow acute respiratory infection (ARI) among children under five in Bangladesh. METHODS: A total of 6863 under-five children were eligible for our analysis, retrieved from Bangladesh Demographic and Health Survey (BDHS), 2014. ARI cases were defined if a child experienced coughing with short and rapid breathing at the chest that occurred during 2 weeks prior to the study. Logistic regression and systematic review methods were appraised to explore the various risk factors involving ARI in Bangladesh. Furthermore, a trend analysis was performed to overlook the historical trend of ARI prevalence and affiliated determinants from 1996/97 to 2017/18 in Bangladesh. RESULTS: Over the past two decades, Bangladesh experienced a significant drop in ARI prevalence from 12.8% in 1996 to only 3.0% in 2018. The cross-sectional findings revealed that boys (OR = 1.35, 95% CI: 1.03-1.78), stunted children (OR = 1.35, 95% CI: 1.03-1.78) and mothers with primary or no education (OR = 2.53, 95% CI: 1.43-4.90) and secondary education (OR = 1.77, 95% CI: 1.00-3.44) have the higher odds of ARI than their counterparts. CONCLUSION: Acute respiratory infection prevalence significantly declined in Bangladesh, while boys, stunted children and uneducated or primary educated mothers were identified as potential risk factors.
