Association between depressive symptoms of mothers and eating behaviors of school-going children in Urban Bangladesh: A cross-sectional study.

OBJECTIVE: This study aimed to investigate the association between depressive symptoms among mothers and the eating behaviors of their school-going children in Urban Bangladesh. MATERIALS AND METHODS: This analytical cross-sectional study was conducted in the context of the urban area of Bangladesh. A multistage sampling technique was applied to select 324 children's mothers in Dhaka City. Data were collected from both city corporation settings in Dhaka, Bangladesh. Semi-structured questionnaires were used in this study. We estimated the depressive symptoms among mothers using the Zung Self-Rating Depression Scale. We examined the association of mothers of school-going children's socio-demographic variables and eating behaviors of school-going children with their mother's depression by using chi-square and evaluating the impact of these variables on mothers' depression through univariate and multivariate binary logistic regression. RESULTS: In our study, 57.7% of the mothers of school-going children had depressive symptoms, and 42.3% had no depressive symptoms. The study explored that consuming fewer vegetables (AOR = 0.237, 95% CI: 0.099-0.569), taking fewer fruits (AOR = 0.177, 95% CI: 0.093-0.337), and interestingly, taking fast food less than 4 days per week (AOR = 3.024, 95% CI: 1.517-6.031) were significantly associated with mothers' depressive symptoms. CONCLUSION: Mothers with depressive symptoms of school-going children in Dhaka city are alarmingly high as a grave concern. The eating behaviors of children are associated with their mothers' depressive symptoms. With an aim to build rigorous awareness on depression and child's healthy eating behaviors, it is imperative to arrange health education and awareness related programs.

Studies on Synthesis, Characterization, and Photocatalytic Activity of TiO2 and Cr-Doped TiO2 for the Degradation of p-Chlorophenol.

TiO2 and Cr-TiO2 nanoparticles (NPs) have been synthesized by the sol-gel method using titanium isopropoxide as the precursor of Titania. The prepared samples were analyzed by employing scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier transform infrared analyses. Under UV irradiation, the photocatalytic activities of TiO2 and Cr-TiO2 were observed by estimating the % degradation of p-chlorophenol (PCP) as a sample pollutant. The extent of degradation was investigated, varying the catalyst dosage, initial PCP concentration, irradiation time, and solution pH. The experimental results show that efficiency of catalysts initially increases but decreases later on, whereas the % degradation of PCP is the highest at its lowest initial concentration. For TiO2 and Cr-TiO2 NPs at their optimal catalyst dosage of 2.0 g/L, acidic pH, and with UV irradiation for 90 min, the observed % degradation of PCP is 50.23 ± 3.12 and 66.51 ± 2.14%, respectively. Thus, the prepared Cr-TiO2 NPs have enhanced the degradation efficiency of PCP with an irradiation time which is four time less than those reported earlier. From the kinetics analysis, the degradation reaction of PCP is found to follow a pseudo-first-order model and the rate constants are 0.0075 and 0.0122 min-1 for pure TiO2 and Cr-TiO2 NPs, respectively. The present study has further revealed that owing to the lower rate of electron-hole pair recombination, the photocatalytic activity of Cr-TiO2 NPs becomes higher than that of TiO2. Therefore, as viable photocatalytic agents, Cr-TiO2 NPs are suggested to be used also for efficient degradation of other organic pollutants.

Prevalence and factors associated with depression among the mothers of school-going children in Dhaka city, Bangladesh: A multi stage sampling-based study.

BACKGROUND: Motherhood is associated with extra stress, and mothers of young children are particularly prone to developing depression and mental health problems. METHODOLOGY: This analytical cross-sectional study was conducted in Dhaka city, Bangladesh, from June to December 2019. Mothers of school-going children were recruited through a multistage sampling technique. Dhaka city was divided into two divisions and then further subdivided into public and private sectors. Six schools were selected from each sector by using a simple random sampling technique. A list of class five to eight students were collected from each school by systematic random sampling. Data were collected through face-to-face interviews using semi-structured questionnaires. The rate of depressive symptoms was measured by the validated Zung Self-Rating Depression Scale (SDS). RESULT: A total of 324 women participated in this study; the majority of the women (85.5%) were Muslim, 67.0% were housewives, and 53.1% had a girl child. Among the women, 15.4% had mild, 22.2% had moderate, and 20.1% had severe depression. Most of the child's behavioral and lifestyle factors were associated with the mother's depression. Adjusted analyses indicate that if a child is often unhappy, depressed, or tearful [(OR (95%CI = 22.27 (8.39-59.11)], gets nervous in new situations or easily loses confidence [(OR (95%CI) = 5.45 (2.96-10.00)], often lies or cheats [(OR (95%CI) = 8.93 (3.76-21.22)], gets afraid easily [(OR (95%CI) = 7.09 (3.79-13.24)], watches television for 3 h or more [(OR (95%CI) = 23.77 (6.46-87.48)] browses the internet for 3 h or more [(OR (95%CI = 7.37 (2.76-19.67)] were associated with mother's depression. CONCLUSION: The study concludes that depression among the mothers of school-going children in Dhaka city of Bangladesh is high. Several lifestyles and behavioral factors of school-going children are significantly associated with the mothers' depression.

Familial and socio-cultural barriers in maintaining tobacco-free homes in Bangladesh: a comparative cross-sectional study.

OBJECTIVES: Children, pregnant women and the elderly at a global level are all being dangerously exposed to tobacco use in the household (HH). However, there is no understanding of the familial and socio-cultural factors that provide barriers to ensuring tobacco-free homes in Bangladesh either in urban or rural areas (U&RAs). This study therefore investigates those barriers to help enable a move towards tobacco-free homes in Bangladesh. DESIGN: Comparative cross-sectional study. SETTINGS: Data were collected from both urban and rural settings in Bangladesh. PARTICIPANTS: A probability proportional sampling procedure was used to select 808 participants in U&RAs out of a total of 3715 tobacco users. Semi-structured interviews through the use of a questionnaire were conducted with the participants followed by a multivariate logistic regression analysis of the data in order to explore the familial and socio-cultural factors associated with tobacco use at home. RESULTS: The prevalence of tobacco use at home was 25.7% in urban areas and 47.6% in rural areas. In urban areas: marital status (adjusted OR (AOR)=3.23, 95% CI 1.37 to 6.61), education (AOR=2.14, 95% CI 1.15 to 3.99), the smoking habits of elderly family members (AOR=1.81, 95% CI 0.91 to 2.89), offering tobacco as a traditional form of leisure activity at home (AOR=1.85, 95% CI 0.94 to 2.95) and lack of religious practices (AOR=2.39, 95% CI 1.27 to 4.54) were identified as significant socio-cultural predictors associated with tobacco use at home. In rural areas: age (AOR=5.11, 95% CI 2.03 to 12.83), extended family (AOR=3.08, 95% CI 1.28 to 7.38), lack of religious practices (AOR=4.23, 95% CI 2.32 to 7.72), using children to buy or carry tobacco (AOR=3.33, 95% CI 1.11 to 9.99), lack of family guidance (AOR=4.27, 95% CI 2.45 to 7.42) and offering tobacco as a traditional form of leisure activity at home (AOR=3.81, 95% CI 2.23 to 6.47) were identified as significant determinants for tobacco use at home. CONCLUSION: This study concludes that socio-cultural traditions and familial norms in Bangladesh provide significant barriers for enabling tobacco-free homes. The identification of these barriers can aid policymakers and programme planners in Bangladesh in devising appropriate measures to mitigate the deadly consequences of tobacco use in the home. The consequences also include the dangers involved in family members being exposed to secondhand smoke.

Increased concentration of serum MDA, decreased antioxidants and altered trace elements and macro-minerals are linked to obesity among Bangladeshi population.

BACKGROUND AND OBJECTIVE: Obesity is an emerging public health concern in Bangladesh. This study aimed to find the levels of the serum malondialdehyde (MDA), non-enzymatic antioxidants (vitamin A, C and E), trace elements (zinc and iron) and macro-minerals (calcium, potassium and sodium) in obesity and its action in disease advancement. METHODS: Level of lipid peroxidation was estimated by measurement of the serum concentrations of malondialdehyde (MDA). Vitamin A and E concentration was found by RP-HPLC method and vitamin C was assessed for serum ascorbic acid by UV spectrophotometric method. Serum trace elements (Zn and Fe) and macro-minerals (Na, K and Ca) were estimated by Atomic Absorption Spectroscopy (AAS). RESULTS: Our study observed significantly elevated concentrations of MDA (p < 0.001) and depleted concentrations of antioxidants (vitamin A, E and C) (p < 0.05) in the patient than control group. Analysis of serum trace elements (Zn and Fe) and macro-minerals (Na, K and Ca) and found that the mean values of Zn, Fe, Na, K and Ca were 0.39 ±â€¯0.02 and 0.43 ±â€¯0.03, 3284.81 ±â€¯34.51, 162.18 ±â€¯3.72, 44.62 ±â€¯2.13 mg/L for the patient and 0.91 ±â€¯0.13, 0.88 ±â€¯0.06, 2562.74 ±â€¯95.92, 243.58 ±â€¯8.97, 87.66 ±â€¯2.10 mg/L for the controls, consequently. There was a substantial difference in trace elements and macro-minerals between the patients and controls (p < 0.001). CONCLUSION: Our study proposes that increased serum concentrations of MDA and decreased non-enzymatic antioxidant and altered trace elements and macro-minerals are powerfully related with obesity.

Prevalence and predictors of tobacco smoking among university students in Sylhet Division, Bangladesh.

BACKGROUND: Among university students, large numbers are involved with smoking and suffer from many chronic diseases. This study examined tobacco smoking prevalence and potential predictors among university students in Sylhet Division, Bangladesh. METHODS: A total of 416 students were selected for face-to-face interviews. Logistic regression analysis was used to fulfil the specific objectives of the study. RESULTS: It was discovered that the prevalence of smoking among university students in Sylhet Division was 37% and almost half of current male students were smokers. Mother's occupation and peer smoking status were found to be significant factors. Although data were collected using multistage sampling, the stages (type of university, universities, departments and academic levels) were insignificant with smoking status. There is a 2.1 times greater likelihood of a student becoming a smoker if a close friend is a smoker. The adjusted living expenses (>$100) was a proactive factor, though individually it was a significant factor. CONCLUSIONS: This study and previous studies found that smoking initiation among female students is negligible, so gender-specific health promotion and intervention is needed in Bangladesh. Tobacco control awareness programs and 'No smoking' signage should be displayed within university campuses and sanctioned by university authorities.

Molecular docking analysis of known flavonoids as duel COX-2 inhibitors in the context of cancer.

Cyclooxygenase-2 (COX-2) catalyzed synthesis of prostaglandin E2 and it associates with tumor growth, infiltration, and metastasis in preclinical experiments. Known inhibitors against COX-2 exhibit toxicity. Therefore, it is of interest to screen natural compounds like flavanoids against COX-2. Molecular docking using 12 known flavanoids against COX-2 by FlexX and of ArgusLab were performed. All compounds showed a favourable binding energy of >-10 KJ/mol in FlexX and > -8 kcal/mol in ArgusLab. However, this data requires in vitro and in vivo verification for further consideration.

Stochastic Frontier approach and Data Envelopment Analysis to Total Factor Productivity and efficiency measurement of Bangladeshi rice.

The objective of this paper is to apply the Translog Stochastic Frontier production model (SFA) and Data Envelopment Analysis (DEA) to estimate efficiencies over time and the Total Factor Productivity (TFP) growth rate for Bangladeshi rice crops (Aus, Aman and Boro) throughout the most recent data available comprising the period 1989-2008. Results indicate that technical efficiency was observed as higher for Boro among the three types of rice, but the overall technical efficiency of rice production was found around 50%. Although positive changes exist in TFP for the sample analyzed, the average growth rate of TFP for rice production was estimated at almost the same levels for both Translog SFA with half normal distribution and DEA. Estimated TFP from SFA is forecasted with ARIMA (2, 0, 0) model. ARIMA (1, 0, 0) model is used to forecast TFP of Aman from DEA estimation.
