In Bangladesh, morbidity and mortality due to non-communicable diseases (NCDs) has increased over the last few decades. Hypertension is an important risk factor for NCDs, specifically cardiovascular disease. The objective of this study was assess prevalence factors hypertension pre-hypertension among adults in Bangladesh. Data analysis were collected during national NCD Risk Factor Survey Bangladesh conducted 2010 from a representative sample men women, aged 25 years or above. survey adopted...

To guarantee quality assurance and control of the received radiation dose treatment level, Thermoluminescent Dosimeter (TLD) is frequently employed in personal monitoring equipment. TLDs are commonly used to ensure precise delivery doses patients clinical radiotherapy, diagnostic radiology, monitoring, environmental dosimetry. Even though manufacturer made all same batch, their sensitivity varies. This study aims examine TLD crystal calibration process, particular, linearity individual...

Malnutrition is a persistent problem for both children and mother throughout the world. In developing countries malnutrition an important root of infant young child mortality, morbidity reduced life span. It considered that if cannot be prevented, it will impossible to achieve many Millennium Development Goals (MDGs) including goals on extreme poverty hungry, primary education, incidence infectious diseases. The World Summit Children in 1990 recognized as contributing factor half all deaths...

Malnutrition among the rural Bangladeshi women of reproductive age is still very high. This high prevalence attributes to a range adverse health consequences on and their offspring. A total 2341 aged between 20 45 years residing in study area were interviewed this cross-sectional study. Information socioeconomic variables, nutritional status, pregnancy-related history was obtained using interviewer administered questionnaire. 34% suffer from malnutrition. multivariate analysis shows...

Purpose The purpose of this paper is to generate three types forecasts, namely, historical, ex‐post and ex‐ante, using the world famous Box‐Jenkins time series models for motor, mash mung prices in Bangladesh. Design/methodology/approach on basis which these forecasts have been computed were selected by six important information criteria such as Akaike's Information Criterion (AIC), Schwarz's Bayesian (BIC), Theil's R 2 , SE( σ ) Mean Absolute Percent Errors (MAPEs). In order examine...

Overdispersion in count data analysis is very common many practical fields of health sciences. Ignorance the presence overdispersion such may cause misleading inferences and thus lead to incorrect interpretations results. Researchers should account for consequences need select correct choice models data. In this paper, Generalized Linear Models (GLMs) are applied modelling antenatal care (ANC) extracted from Bangladesh Demographic Health Survey (BDHS) 2014. Pearson chi-square different score...

To investigate the prevalence of number children ever born (CEB) and its associated determinants among women aged 15-49 years in Bangladesh.We used clustered data extracted from last two Bangladesh Demographic Health Surveys (BDHS 2014 BDHS 2017-2018). A two-stage stratified sampling was both surveys. Mixed logistic regression modelling approach for binary responses adapted to accommodate clustering effects via generalised linear mixed model framework.The study is based on 15 924...

Generalized additive mixed models (GAMMs) extend generalized linear (GLMMs) to allow the covariates be nonparametrically associated with response. Estimation of such for correlated binary data is challenging and estimation techniques often yield contrasting results. Via simulations, we compared performance Bayesian likelihood-based methods estimating components GAMMs under a wide range conditions. For method, also assessed sensitivity results choice prior distributions variance components....

In time series analysis, over-differencing is a common phenomenon to make the data be stationary. However, it not always good idea take in order ensure stationarity of data. this paper, effect has been investigated via simulation study observe how far or close fitted model from true one. Simulation results show that found different and very because most scenarios considered study. practice, may worthy consider differencing as well suitable transformation Both are used for non-stationary on...

The most commonly used model selection criterion, Akaike’s Information Criterion (AIC), cannot be when the Generalized Estimating Equations (GEE) approach is considered for analyzing multivariate binary response. Recently, a modified version of AIC (mAIC) which based on quasi-likelihood function proposed as criterion. This criterion can in GEE setup. In this study, an application mAIC showed selecting important covariates associated with pregnancy related complications Bangladeshi women.

Background Maternal morbidities especially life-threatening pregnancy complications are major health concerns in developing countries. The main aim is to investigate the prevalence of maternal morbidity during and its determinants among women from urban areas Bangladesh. Methods secondary data were used extracted latest Bangladesh Urban Health Survey (BUHS) 2013. Several statistical models: Poisson, negative binomial (NB) mixed Poisson adapted compared explore best model for investigating...

Aims: To compare the risk factors and pattern of coronary artery involvement in young acute syndrome patients with that elderly.Methods: This was a cross sectional analytic study done Department Cardiology, Sir Salimullah Medical College Mitford Hospital during November 2015 to October 2016.Results: Study population divided into two subgroups, those 18-40 years were considered as >40 elderly. Young had greater prevalence smoking, dyslipidemia positive family history Ischemic Heart Disease...

To determine the presence of enterohaemorrhagic Escherichia coli (EHEC), 50 water samples three different lakes in Dhaka, Bangladesh were studied. A total 90 strains examined thoroughly to isolate sorbitol non-fermenting (NSF) E. coli. Twelve isolates (13.3%) from 5 found be nonfermenter, which further screened for rhamnose, cellobiose and sucrose fermentation. Eleven (12.2%) also tested negative fermentation, while only 3 (3.3%) them rhamnose non-fermenting. Biochemical tests confirmed that...

Background: Dengue is a growing public health problem globally including Bangladesh. This study carried out to find the seroprevalence of dengue fever in Chittagong. Methods: About 1181 serum samples were tested from suspected patients for IgM and IgG antibodies by immunochromatographic methods. Results: Among them, 533 (45.13%) seropositive. seropositive cases 213 (39.96%) positive, 227 (42.59%) positive 93 (17.45%) both positive. Conclusions: A high percentage among demands early careful...

Background: Extended Spectrum b -Lactameses Producing Organisms (ESBLs) are increasing in number and causing more severe infections because of their continuous mutation multidrug resistance property with limited therapeutic option.Aims Objectives: Present study was undertaken to detect the prevalence ESBLs producing bacteria wound infection, so as provide a base line data treating them & prevent unnecessary use antibioticsMethods: Isolated gram-negative initially screened by Minimum...

Poisson regression (PR) is commonly used as the base model for analyzing count data with restrictive equidispersion property. However, overdispersed nature of very common in health sciences. In such cases, PR produces misleading inferences and hence give incorrect interpretations results. Mixed individual--level random effects (MPR_ILRE) a further improvement data. We compare MPR_ILRE PR, quasi-Poisson (Q_PR) negative binomial (NBR) modelling antenatal care (ANC) extracted from latest...
