Purpose Bangladesh has experienced a rapid epidemiological transition from communicable to non-communicable diseases (NCDs) in recent decades. There is, however, limited evidence about multidimensional determinants of NCDs this population. The BangladEsh Longitudinal Investigation Emerging Vascular and nonvascular Events (BELIEVE) study is household-based prospective cohort established investigate biological, behavioural, environmental broader NCDs. Participants Between January 2016 March...

Indoor air concentrations of volatile organic compounds (VOCs), carbon monoxide (CO), dioxide (CO2), nitrogen (NO2), and dust particles were measured for 49 biomass 46 fossil fuel users in urban slums Dhaka, Bangladesh. The health impacts these pollutants assessed on 65 51 children under five years old from families who use as main source energy, respectively. Mean CO found to be significantly higher (P = 0.010), while geometric mean benzene, xylene, toluene, hexane, total VOCs, NO2 < 0.01)...

While the functionality and healthy food value of red rice have increased its popularity, such that market demand for it is expected to rise, most strains suffer from low grain yield. To perform diversity population structure analyses germplasm, therefore, becomes essential improving yields commercial production. In this study, fifty germplasm Bangladesh Rice Research Institute (BRRI) genebank were characterized both morphologically genetically using simple sequence repeat (SSR) markers....

Objectives This study aims to describe the prevalence of non-communicable disease (NCD) risk factors among urban poor in Bangladesh. Design We conducted a community-based cross-sectional epidemiological study. Setting The was shantytown city Dhaka. There were 8604 households with 34 170 residents community. Those categorised into two wealth strata based on housing structure. Participants targeted aged 18–64 years. A total 2986 eligible one individual selected by simple random sampling...

This study assessed subjective symptoms related to indoor concentrations of chemicals among residents in a housing estate Dalian, China, where air pollution by interior decoration materials has recently become major health problem. Fifty-nine males and 50 females were surveyed for their sick building syndrome. Formaldehyde (HCHO), NO2, volatile organic compounds (VOCs) dwellings collected using diffusion sampler measured GC/MS. For with one or more the past, HCHO, butanol 1,2-dichloroethane...

In order clarify possible differences in metabolism diabetics, we measured urinary iAs metabolites diabetic cases and non-diabetic control subjects Faridpur, an arsenic-contaminated area Bangladesh. Physician-diagnosed type 2 (140 persons) controls (180 were recruited. Drinking water spot urine samples collected. Mean concentrations total drinking did not differ between (85.1 μg/L) (85.8...

While the pleasant scent of aromatic rice is making it more popular, with demand for expected to rise in future, varieties this have low yield potential. Genetic diversity and population structure germplasm provide valuable information improvement which has potential market value farm profit. Here, we show 113 based on phenotypic genotypic traits. Phenotypic traits showed that considerable variation existed across germplasm. Based Shannon-Weaver index, most variable trait was lemma-palea...

Indoor air pollutants from biomass combustion pose a risk for respiratory diseases in children. It is plausible that distinct differences the indoor quality (IAQ) exist between urban and rural areas developing countries since living environment these two are quite different. We have investigated possible IAQ Dhaka, Bangladesh association of such with incidence some non-respiratory symptoms children families using fuel.Indoor concentrations carbon monoxide (CO), dioxide (CO(2)), dust...

Abstract Background Globally, older population (aged ≥60 years) comprise 11% of the total population, and 23% them are malnourished. Lack knowledge education, adverse dietary habits, depression or psychological disorders, poor oral dental health, disability, diseases reported factors responsible for malnutrition among them. Geriatric people 7.5% Bangladesh, almost a quarter But there is scarce data on associated with nutritional status in Bangladesh. Methods A cross-sectional study was...
