This study examined the association between women's attitudes towards wife-beating and their utilization of reproductive healthcare services. Two waves of Bangladesh Demographic and Health Survey data were analyzed using multivariate regression. Outcome variables were a set of reproductive healthcare services, namely contraception use, modern contraception use, antenatal visit by skilled health professionals (SHP), delivery in healthcare facilities, delivery by SHP and postnatal check up by SHP. Attitudes towards abuse were assessed by a set of five questions that asked the situation under which 'hitting or beating' one's wife is justifiable. Around 32% of the participants reported that hitting or beating wife by husband was justified in certain situations. There is a gradient in the relationship between...

This study examines the effect of termination of EBF during the first 2, 4 and 6 months of birth on a set of adverse health and nutritional outcomes of infants. Three waves of Bangladesh Demographic and Health Survey data were analysed using multivariate regression. The adverse health outcomes were: an episode of diarrhea, fever or acute respiratory infection (ARI) during the 2 weeks prior to the survey. Nutritional outcomes were assessed by stunting (height-for-age), wasting (weight-for-height) and underweight (weight-for-age). Population attributable fraction was calculated to estimate percentages of these six outcomes that could have been prevented by supplying EBF. Fifty-six percent of infants were exclusively breastfed during the first 6 months. Lack of EBF increased the odds of diarrhea, fever and ARI. Among t...

We assess the association between HAP and risk of selected adverse birth and maternal health outcomes. Data for this study were extracted from Bangladesh Demographic and Health Survey conducted during 2007-2014. Selected adverse birth outcomes were acute respiratory infection (ARI) among children, stillbirth, low birth weight (LBW), under-five mortality, neonatal mortality and infant mortality. Maternal pregnancy complications and cesarean delivery were considered as the adverse maternal health outcomes. Place of cooking, use of solid fuel within the house boundary and in living room were the exposure variables. To examine the association between exposure and outcome variables, we used a series of multiple logistic regression models accounted for complex survey design. Around 90% of the respondents used solid fuel within th...

This rise is not fully accounted for by increases in clinical factors which indicate the need for CS. We investigated the socio-demographic predictors of CS and the average annual rates of CS in Bangladesh between 2004 and 2014. Data were derived from four waves of nationally representative Bangladesh Demographic and Health Survey (BDHS) conducted between 2004 and 2014. Rate of change analysis was used to calculate the average annual rate of increase in CS from 2004 to 2014, by socio-demographic categories. Multi-level logistic regression was used to identify the socio-demographic predictors of CS in a cross-sectional analysis of the 2014 BDHS data. CS rates increased from 3.5% in 2004 to 23% in 2014. The average annual rate of increase in CS was higher among women of advanced maternal age (≥35 years), urban areas, and relatively high socio-economic status; with higher education, and who regularl...

It is a rare food-borne opportunistic pathogen which causes neonatal sepsis, bacteremia, and urinary tract infections. T. ptyseos has been also cultured from various food sources around the world. It is difficult to determine the source of the infection in the patients (especially newborns) due to low information about the epidemiology of T. ptyseos. The current study aimed to investigate the isolation, identification and antimicrobial susceptibility pattern of T. ptyseos strains from the consumed powdered infant formula milk (PIF) in hospital neonatal intensive care unit (NICU). A total of 125 powdered infant formula milk (PIF) samples were purchased from drug stores from June 2011 to March 2012. T. ptyseos was isolated according to food and drug administration (FDA) method. For final confirmation, biochemical testes embedded in API-20E system were used. Drug susceptibility test was performed using the disc diffusion method, according to clinical and laboratory standard institute (CLSI) recommendations. Results of the study showed that, out of 125 samples, T. ptyseos was isolated from four (3/2%) PIF samples. All isolated strains (100%) were resistant to ampicillin, carbenicillin, cotrimoxazole and amoxicillin. The present study was the first report on the isolation and identification of T. ptyseos from PIF in Iran. T. ptyseos are frequently present in various kinds of foods; therefore, further investigation on these samples is required. It is necessary to track the T. ptyseos in a wide variety of foods and individuals especially in immunocompromised people such as human immunodeficiency virus (HIV)-positive patients to reveal the possible routes of transmission of this pathogen to humans. In addition, molecular studies are required to determine the genetic relationship between T. ptyseos strains isolated from different sources.
