RESUMO
In Bangladesh, body soaps are very popular among consumers due to their flavors and low alkali content. The current study assesses the contamination of several trace metals (TMs) such as iron (Fe), copper (Cu), zinc (Zn), chromium (Cr), manganese (Mn), nickel (Ni), cadmium (Cd), and lead (Pb) in some of the body soaps most commonly used in Bangladesh. The concentrations of Fe, Cu, Zn, Cr, and Mn were found within the acceptable limits stipulated by the World Health Organization (WHO); however, in contrast, the concentrations of Ni, Cd, and Pb remained below the detection limit. Notably, the concentration of Cr in two soap samples (S-2, S-3) out of twenty-one soap samples exceeded the permissible limit stipulated by the WHO. Health risks associated with the TM intake via dermal routes were evaluated in terms of chronic daily intake (CDI) and hazard quotient (HQ). The results indicated that no non-carcinogenic risks (NCR) are likely to occur owing to the use of those body soaps. The carcinogenic risk (CR) estimated for Cr revealed no possibility of probable carcinogenic diseases. Though the NCR and CR are unlikely to occur resulting from the long-term uses of these soaps, the present study provides baseline information on the possible contaminations of TMs in the beauty soaps that do not seem to have been reported so far in Bangladesh. In light of the above information, it can be concluded that the presence of TMs in the body soaps could be a warning for people in general thereby suggesting continuous monitoring.
RESUMO
In low-resource settings like Bangladesh, there is a dearth of research on the mental health of university students. This pilot study aimed to identify the prevalence of depressive symptoms, loneliness, and physical activities as well as the associated factors of depressive symptoms among graduate students in a public university of Bangladesh. This cross-sectional study was carried out among 323 graduate students between February 2019 and May 2019. By the convenience sampling technique, data were collected by a pretested, structured questionnaire. Depressive symptoms were assessed by the validated Patient Health Questionnaire-9 (PHQ-9) tool with a cut-off score of ≥10 vs. less; University of California, Los Angeles (UCLA) loneliness scale was applied to assess loneliness, International Physical Activity Questionnaire (IPAQ) scale was used to measure physical activity level. The overall prevalence of depressive symptoms was 52% and about 43% of participants felt most lonely. About 32.8% of students were involved in low physical activity. Being female, from lower income families, having poor academic performance, experiencing shorter sleep time, lower physical activity, and being lonely were potential risk factors for depressive symptoms among graduate university students. A positive correlation was found between loneliness and depressive symptoms of students (r = 0.367, p < 0.001). The higher prevalence of depressive symptoms among Bangladeshi graduate university students suggests the need for situation analysis, confirmatory clinical diagnosis, in-depth qualitative explorations, and large-scale surveys to explore the burden of such disorders and design appropriate low-intensity interventions like implementing student counselling service, offering mental assistance or other mental health support program in the country.
