This paper aims to investigate the role of educational institutes in heritage management from the local and national policy level to safeguard archaeological heritage perspectives in the Lalmai-Mainamati area, cumilla, Bangladesh. Lalmai-Mainamati area is one of the historical places in Bangladesh and in this area almost 50 archaeological sites were marked by the department of archaeology (DOA), and most of the sites represent our historical remains from 9th to 12 century BC. The Department of archaeology maintained all of these sites under antiquity act 1968 but the drawback of manpower resources and financial budget is that most of the sites are unprotected and lack proper maintenance process. Local people, tourists, Fanatic society, and mischievous people are ruining our historical past evidence in many ways. From the causes of these casualties, people are not aware of it and they are not realizing the importance of our heritage practicing and safeguarding lack of proper information & instruction when they visit these historical places or are attached somehow with these archaeological sites. This paper deals with how our educational institute can play a vital role in safeguarding archaeological heritage in many ways perspectives on the Lalmai-Mainamati area.

Good hygiene and sanitation are essential for the prevention of infectious diseases. Immunization is one of the most important public health interventions to reduce both morbidity and mortality of infectious diseases. Thus, the survey study aimed to determine the status of hygienic practices and assess the immunization coverage among 12-59 months old children in urban slums. A cross-sectional study was conducted among 259 under five children's (12-59 months) in Barisal city, Bangladesh, from June to December 2019 using a structured questionnaire. Data was collected by interviewing the mothers from different slum areas. Chi-squared test and multiple logistic regression models were used to explore the association. Prevalence of good hygiene practices status was 65.3% and fully immunized was 71.4%. Joint family (AOR=0.54; 95% CI: 0.31-0.95; P

Accidental foreign body ingestion is common in the pediatric age group particularly between 6 months and 5 years. Most ingested foreign bodies pass easily through the esophagus, into the stomach, and are expelled from the body without complications. However, endoscopic removal will require only 10% - 20% of cases to avoid complications. We present the endoscopic removal of a metallic hair clip in the duodenum of an 18 month old child that was unnoticed initially and diagnosed incidentally.

Human immunodeficiency Virus (HIV) seropositive individual is at risk of developing disease of cardiovascular system (CVD). There are scarce of research work regarding this field in Bangladesh. Considering scarcity, this study was conducted at anti-retroviral therapy (ART) center of Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh to find out the frequency of the CVD and their common risk factors in HIV seropositive patients from March 2017 to September 2019. Different CVD risk factors were assessed in this study. The demographic data were assessed and World Health Organization STEPS questionnaire were used to collect demographic data. The 10-year CVD risk was calculated by using the Framingham coronary risk score (FRS). Mean age of study population was 38, SD= 9.8. Among them sixty-five (65%) were men and thirty-five (35%) were women. About one third were overweight followed by 5% were obese. High cholesterolemia, high triglyceridemia, high low-density lipoprotein (LDL) and low high-density lipoprotein (HDL) were found in 23%, 58%, 14%. and 63% of the HIV patent, respectively. Hypertension was present in 19% and diabetes in 15% of the patients. In Framingham risk score, 19% of the participants had intermediate to high risk of cardiovascular disease within 10 years. The cardiovascular risk factors were common in HIV patients attending ART center of BSMMU, where base line 10-years CVD risk was low. People living with HIV appear to be an imminent risk to develop CVD. Bangladesh Med J. 2021 May; 50(2) : 40-44

Relaxin (RLX) is a hormone that stimulates renal vasodilation during early pregnancy. Recombinant RLX may have potential as a treatment for heart failure and chronic kidney disease, but its application has been limited in part due to uncertainties about its mechanism of action, and particularly its effect on glomerular capillary hydrostatic pressure (Pgc) and fluid status. The objective of this study was to couple mathematical modeling with experimental observations of the renal hemodynamic and natriuretic response to RLX, in order to quantitatively describe the mechanistic effects of relaxin on the kidney, and to predict its effect on clinically difficult-to-measure variables such as Pgc. Utilizing a previously developed mathematical model of kidney function and hemodynamics, we began by hypothesizing a minimum set of RLX mechanisms (afferent/efferent vasodilation), fitting the available hemodynamic/natriuretic response in two previously published rat studies (GFR, renal plasma flow (RPF), mean arterial pressure (MAP), sodium and water excretion), and adding additional RLX mechanisms to the model only when the minimal set could not explain available data. We found that changes in renal vascular resistances alone were sufficient to reproduce observed changes in RPF, but insufficient to explain other data features. Experimental studies reported much larger increases in sodium excretion relative to water excretion with RLX, and this effect could only be reproduced if an effect of RLX on the osmotic setpoint for vasopressin release was included in the model – a mechanism that has previously been reported in ovariectomized rats treated with RLX. A small effect of RLX on heart rate was necessary to produce observed changes in MAP.In addition, the single experimental study in which Pgc has been measured with RLX reported a rise in GFR but fall in Pgc, and this difference could not be explained mathematically by relative afferent/efferent dilation or by downstream shifting of the filtration equilibrium with increased RPF; it could only be reproduced mathematically if RLX was assumed to large positive effect on glomerular membrane permeability. However, the magnitude of this effect is difficult to justify physiologically. Thus, while the model can be forced to fit this limited data, further study is needed to understand whether and how RLX might have such large permeability effects.The fitted model was then able to make predictions consistent with observed renal responses in human subjects, and these effects were better predicted when the RLX effect on permeability was excluded, further suggesting that this effect may not be real. In these simulations, RLX had no net effect on Pgc. In conclusion, while some uncertainty remains, this analysis suggests that RLX acts primarily by dilating the afferent and efferent arterioles and shifting the osmotic setpoint for vasopressin release.

Budd-Chiari syndrome (BCS) is the clinical spectrum presenting with hepatic venous outflow obstruction from the hepatic veins to the junction of the inferior vena cava (IVC) and the right atrium. This syndrome is rare in infants and children, which leads to misdiagnoses or delayed diagnoses. Clinical presentations may be non-specific. A high index of suspicion and imaging findings may help in early diagnosis of this condition. We report a rare case of BCS in a 6-week-old male infant who presented with jaundice and gradual abdominal distension. He was successfully treated with rivaroxaban.

We know that many people suffer from depression, anxiety, stress, hypertension, and many more mental illnesses in this pandemic situation. As a result, the condition of their mental health is getting bad to worse. However, very few of them can consult a psychiatrist, therapist, or professional who'll guide them properly to get rid of their problems. Keeping that in mind, we came up with an idea to build an intelligent web app that will help people suffering from mental health but not consult a doctor/psychiatrist. This system allows professionals to check and follow up on their patients from remote areas. Both patients and professionals can communicate through audio, video, voice, and text messages. Users, as a patient, can also directly search for professional psychiatrists/ doctors or consultants and request appointments through the app to get guidelines. Professionals can check patients' history, review appointments, accept them, schedule them, and provide guidelines for improvement. Patients will also have the facility to get a quick in-app therapy to improve their mindset if they feel they're not okay, which includes breathing exercise, some cardio exercise, a short audio clip on a motivational story, and a feature that will allow expressing user's hidden thoughts or some words they can share with our live chat agent. This system can play a significant role in the life of the people who are introverts, shy from sharing their mental health issues, and the people who don't have the opportunity to consult a mental health professional from their position directly. The overall system has been tested in a lab environment to ensure the best user experience, including a very user-friendly interface. It shows more efficiency in its service to help people countrywide who are suffering from mental illness.

Study design: The study design was cross-sectional. Objective: Assessment of the health-related quality of life (HRQoL) of primary caregivers of people with tetraplegia owing to traumatic SCI. Setting: A total of 48 samples were selected conveniently for this study from the Centre for the Rehabilitation of the Paralysed (CRP), spinal cord injury unit, at Savar. Methods: Data was collected by using a questionnaire, and health-related quality of life (HRQoL) was assessed by the Short Form-36 (SF-36) health survey questionnaire. Descriptive statistics using SPSS software version 16.0 were used for data analysis, which focused on columns, pie charts, and doughnuts. Results: Among 48 caregivers evaluated, 39 (81.2%) were female and 9 (18.8%) were male, where 22 people (45.8%) were either husbands or wives and 15 people (31.2%) were parents of people with tetraplegia. It was found that most of the caregivers (62.5%) spend about 13–18 hrs/day caring for individuals with tetraplegia. The participants reported lower scores on social functioning and emotional well-being than the other dimensions of SF-36. Conclusion: Primary caregivers of spinal-cord injury patients had low scores on all SF-36 aspects, including social functioning and emotional well-being.

Introduction Exclusive breastfeeding is balanced nutrition for growth and development of the infant, prevents stunting as well as protects from infectious and chronic diseases and has also potential to reduce infant mortality. Thus, the study aimed to assess maternal knowledge, attitudes and other factors associated with exclusive breastfeeding practices. Methods A cross-sectional study was conducted among 385 mothers of children aged ≤12 months in Mother and Child Hospital in Dhaka city, Bangladesh, from June to December 2019 using a structured questionnaire. Data were collected by face-to-face interview from hospital’s outdoors, following simple random sampling process from hospital register list. Chi-squared test and multiple logistic regression models were used to explore the association. Results The prevalence of exclusive breastfeeding was 63.4% for mothers with children aged ≤12 months. Good knowledge (p

Sign language is a form of communication used by the deaf and dumb. However, integrating them into society is challenging because most people do not speak their language. It is a method of generating and disseminating ideas, information, points of view, facts, and sentiments to establish a shared understanding. Unfortunately, almost 5% of the world's population is not blessed with the ability of verbal communication. The situation is the same for Bangladesh. This paper presents a simple, low-cost Bangla sign language (BdSL) recognition model with maximum accuracy to convert signs into Bangla text. We've manually captured images for Bangla sign language following the BdSL model and implemented the dataset to train the system and show output. We used neural networks as a deep learning method to train individual signs to achieve our goals in the suggested model. Using a CNN, we separated the dataset into two parts: training data and test data. The action is mapped to the relevant text in the training data using image processing techniques, and neural networks, so raw images or videos are turned into text that can be read and comprehended with accuracy near 92%. Finally, the system will turn the user's signs and motions into text. It is referred to as "sign language recognition." In the future, This research can also open doors to numerous other applications, like sign language tutorials or dictionaries, and can also help the deaf and dumb search the web or send emails more conveniently. We hope this system will be an excellent opportunity for people who have speaking or hearing disabilities by helping them explore more.

Introduction Menstrual hygiene practices refers to maintaining specific hygiene during menstrual periods. Excused or unexcused school absenteeism can be attributed to adopted menstrual hygiene practices. This study aimed to assess the prevalence of school absenteeism during menstrual cycle and to explore the association of menstrual hygiene practices with school absenteeism among schoolgoing adolescent girls in Bangladesh. Methods A cross-sectional study was conducted from April to November 2019 based on a sample of 442 school-going adolescent girls (aged 10–19 years) from randomly selected nine Girls’ Schools in the Dhaka division, Bangladesh. Data were collected by an interviewer-administered questionnaire and a multiple regression model was applied to assess factors associated with school absenteeism. Results The prevalence of school absenteeism was (35.1%) among school-going adolescent girls in Bangladesh. Factors associated with school absenteeism included older adolescent girls (AOR=2.97; 95% CI: 1.66–5.24, p

Increasing concerns regarding wireless systems’ security are leading researchers to exploit the physical properties of a medium while designing any secured wireless network. The secrecy performance of a mixed radio frequency-free space optical (RF-FSO) system with a variable gain relaying scheme is investigated in this paper under the attempt of wiretapping by an eavesdropper. We assume that the eavesdropper can intrude the target data from the RF link only. Both the RF links (main and eavesdropper) undergo the $\alpha -\mu $ fading statistics and the FSO link experiences the exponentiated Weibull fading statistics. Exploiting the amplify-and-forward (AF) relaying scheme while considering two detection techniques (i.e. heterodyne detection and intensity modulation/direct detection) with pointing error impairments, the mathematical formulations of the unified probability density function and cumulative distribution function are performed for the equivalent signal-to-noise ratio of the considered dual-hop RF-FSO link. Closed-form analytical expressions for average secrecy capacity, secrecy outage probability, and the probability of non-zero secrecy capacity are derived in terms of Meijer’s $G$ and Fox’s $H$ functions to quantify the system performance. Capitalizing on these expressions, the secrecy performance is further analyzed for various channel parameters of RF links, aperture sizes of the receiver, pointing errors, and atmospheric turbulence severity. The results reveal that aperture averaging can improve the secrecy performance remarkably by suppressing the effects of turbulence. Monte Carlo simulations are provided to justify the accuracy of the proposed model.

Early initiation of breastfeeding (EIBF) is crucial for mothers as well as children’s health, and also has the potential to prevent neonatal mortality. Thus, this study aimed to assess the prevalence and factors associated with EIBF among mothers in Dhaka City, Bangladesh. A cross-sectional study was conducted from January to July 2019, based on a sample of 422 mothers of children aged under 6 months. Data were collected by in-person interviews from a hospital’s outdoor through a structured questionnaire consisted of demographic, reproductive, and healthcare utilization information. Association between variables was assessed by multiple logistic regression. The prevalence of EIBF among mothers was 48.3% [95% CI: 43.4–53.3]. Multiple logistic regression showed that being a housewife, having family income of > 10,000 BDT (Bangladeshi currency) per month, mothers education level, being multiparous, normal delivery, ANC (antenatal care) visits for ≥ 3 times, counseling prior to conception, and skin-to-skin contact after delivery significantly increased the likelihood of EIBF among mothers. Besides, mothers who gave birth to low-weight babies and provided pre-lacteal feeds to them were negatively associated with EIBF. EIBF has improved in Bangladesh during MDG era, but progress still remains slower. Key modifiable factors such as maternal education, normal delivery, ANC visits, skin-to-skin contact, and pre-lacteal feeding need to be improved to enhance the EIBF for reducing child malnutrition and mortality.

Diarrhea is a leading cause of death among under five children in developing countries. The burden of child diarrhea in Bangladesh is still significant. Safe water, sanitation, and hygiene (WASH) can limit the events. This study aimed to assess the effectiveness of WASH education of mothers or caregivers on child diarrhea. A community-based randomized control trial was conducted in the selected households of a rural community in Dumki Upazila, Patuakhali from March–June 2019. A total of 202 mothers/caregivers received intervention and 202 did not receive intervention. A pre-structured questionnaire was used to gather information on household WASH activities and diarrheal cases. Baseline data were collected first from the intervention group before providing education. WASH messages were given to the intervention group by face-to-face discussion. Both groups were followed up for diarrheal episodes for 3 months. Diarrheal prevalence of intervening group is compared with that of baseline and control. The results revealed that diarrheal prevalence was 11.4% (95% CI: 7.4–16.59%), 4.0% (95% CI: 1.7–7.65%), and 14.9% (95% CI: 10.25–20.52%) in baseline, intervention, and control group, respectively. Also, diarrhea was found lower in the intervention group than baseline (Z = − 2.524; P value = 0.012) and control (Z = − 1.85; P value = 0.04). WASH interventions were found effective to reduce the diarrheal episodes among under five children in rural community. Further investigation is necessary to assess the long-term effect of such intervention in other similar settings.

Soymilk (SM) is nutritionally nearly equal to milk from cows and is free of cholesterol, gluten, and lactose. This study's objective was to formulate a cholesterol-free soymilk dessert (SOD) and compare it's to commercial desserts (CODs). Results indicated that the CODs contain substantial amounts of cholesterol while SOD does not. Soymilk dessert has more protein, and vitamin E than CODs, but less fat and calcium. In addition, the result also highlighted that SOD has higher number of amino acids compared to CODs. The total antioxidant, flavonoids and phenolics content of SOD were significantly higher than CODs. Furthermore, the

Background Healthcare-associated infections caused by poor hand hygiene (HH) practices can affect both the care seekers and the health care providers (HCPs) while providing primary health care. No study has been conducted on the compliance of HH practices among the primary level HCPs in Bangladesh. Objective The study aimed to assess the compliance rates of HH and its determinant factors among Community Health Care Providers (CHCPs) in Community Clinics (CC). Methods A cross-sectional study was conducted from September 2019 to February 2020 among 150 randomly selected CHCPs with functional HH facilities in Patuakhali district, Bangladesh. Structured interviews and observation tools were used to collect data. Results Good HH compliance among CHCPs was found to be 16.7% (95% CI: 11.3–21.3). Out of all 1218 possible HH opportunities, only 255 (20.9%) resulted in any HH action. Presence of 70% alcohol-based hand sanitiser at the point of care (aOR: 6.4, 95% CI: 1.1–38.3), HH training (aOR: 4.6, 95% CI: 1.1–18.9), displayed visual cues (aOR: 4.4, 95% CI: 1.1–17.7), knowledge about HH (aOR: 3.8, 95% CI: 1.1–13.6) and number of HH opportunities (aOR: 0.6, 95% CI: 0.4–0.8) were factors associated with HH compliance. Discussion Overall HH compliance among CHCPs was relatively low. It was recommended to implement multimodal HH improvement strategies, including a continuous training program, supply of alcohol-based hand rub, reminder, provision of five moments of HH in the training modules and feedback on HH performance.

OBJECTIVE The study aimed to assess the prevalence of depression and its associated factors among university students in Bangladesh. Participants: A total of 403 undergraduate students from Patuakhali Science and Technology University, and Barisal University participated in the study. Method: A cross-sectional study was conducted using Beck's Depression Inventory (BDI). Result: The prevalence of depression (BDI ≥ 14) was 47.14%. Depression was 3.4 times (95% CI: 1.6-7.1), 3.8 times (95% CI: 1.7-8.6), and 3.9 times (95% CI: 1.5-8.9) higher among 2nd, 3rd, and 4th-year students, respectively than 1st-year students. Students with a history of stressful life events (aOR = 2.7, 95% CI: 1.7-4.4), suicidal attempts (aOR = 3.0, 95% CI: 1.2-7.9), and who received inadequate monthly allowance from their family (aOR = 0.53 95% CI: 0.3-0.9) were more likely to develop depressive symptoms. Conclusion: This study reports a high level of depression among university students which needs further discussion, exploration, and calls for designing appropriate interventions.

Galactosemia is an autosomal recessive inheritance and there is cellular deficiency of enzymes leading to defective/impaired metabolism of galactose resulting in toxic byproducts like galactilol, galactose-1-phosphate and galactonate that affect mainly liver, brain, kidneys, lens and gonads. Galactosemia appears as a rare metabolic cause of neonatal cholestasis syndrome (NCS). The classic disease manifestation after the first milk feeding varies in severity from an acute fulminant illness to a more common subacute illness beginning within the first few days of life. Neonatal sepsis is one of the presentations. Galactokinase deficiency results primarily in cataract formation and galactosuria. The preliminary diagnosis of galactosemia in sick neonates and suspected infants is made by Benedict test in several urine specimens and followed by dipstick test to exclude glycosuria. Gold standard test is demonstration of low enzyme activity in erythrocyte. Galactosemia can be detected by newborn screening methods like the Guthrie test using filterpaper blood samples. Classical form of galactosemia should be treated with an absolute galactose restricted diet without waiting for confirmation of the diagnosis. Here we report a case of a 50-dayold boy with features of neonatal cholestasis, diagnosed as galactosemia by using a simple cost effective method. J Enam Med Col 2020; 10(1): 43-48

Studies in ecological stoichiometry highlight that grazer dynamics are affected by insufficient food nutrient content (low phosphorus (P)/carbon (C) ratio) as well as excess food nutrient content (high P:C). Contaminant stressors affect all levels of the biological hierarchy, from cells to organs to organisms to populations to entire ecosystems. Eco-toxicological modeling under the framework of ecological stoichiometry predicts the risk of bio-accumulation of a toxicant under stoichiometric constraints. In this paper, we developed and analyzed a Lotka-Volterra type predator- prey model which explicitly tracks the environmental toxicant as well as the toxicant in the populations under stoichiometric constraints. Analytic, numerical, slow-fast steady state and bifurcation theory are employed to predict the risk of toxicant bio-accumulation under varying food conditions. In some cases, our model predicts different population dynamics, including wide amplitude limit cycles where producer densities exhibit very low values and may be in danger of stochastic extinction.

This study aims to investigate the effects of air quality on child mortality in developing countries. We consider annual data covering the period from 2010 to 2016 of 58 countries and estimate the empirical models using recently developed panel quantile regression with the method of moments (MM-QR). It is found that outdoor air quality (measured by the concentration of PM

Chronic Obstructive Pulmonary Disease (COPD) is a set of lung diseases in which the airways constrict, making it difficult to expel air from the lungs. COPD is caused by longterm lung damage from breathing a potential hazard, mainly frequently cigarette smoking, as well as smoke from other sources and air pollution. Also, some rural areas where people are exposed to dust, flames, and chemicals can contribute to the onset of COPD. COPD is supposed to after 40 years. Some major problems getting short of breath, having cough, wheezing, also produced more sputum, respiration rate abnormal, sometimes getting restless. In Bangladesh, day by day patients with COPD are increasing. So, in this case, need to analyze the symptoms of COPD and finds why it is increasing day by day. In this research, we have taken 101 COPD patients data from the hospital which are in two classes. In the medical sector, work for COPD is rare in Bangladesh. Our goal is to find the most appropriate machine learning approach for COPD prediction which is both computationally efficient and accurate. Decision Tree and Logistic Regression outperformed all other machine learning algorithms, according to the findings in our study.

Background: A Delphi-Based Consensus Statement: Recommendation for Physiotherapy Management and Rehabilitation of people living with Long COVID in Bangladesh Background: Covid-19 is a new and deadly virus with global consequences with special vulnerabilities in Bangladesh. The World Health Organization confirmed 22,451,122,614 cases and 4,627,540 deaths, worldwide (13th September 2021). In the United Kingdom, 1.5% of the estimated population of 970,000, suffers from Long COVID. Physiotherapy plays a vital role both in decreasing the number of deaths during the acute stage and improving function for patients across the spectrum of severity in the acute, sub-acute, and long-term context. Objectives: This Delphi-Based Consensus, provides recommendations for physiotherapy management and rehabilitation of people living with Long COVID. It includes recommendations for physiotherapy management for acute and subacute respiratory complications, a specific prescriptive exercise guideline for fatigue and musculoskeletal dysfunction and for improving psychological outcomes through combination of both counseling and rehabilitation. Methods: A team of 8 national and 6 international experts working in different disciplines were provided with studies on physiotherapy interventions in Long COVID-19 and were asked to provide treatment opinions based on the current literature for musculoskeletal, neurorehabilitation, respiratory, cardiac and psychological health domains. Statements were ranked and presented with individual opinions measured on a 10-point Likert Scale. The mean scores for each intervention were calculated and a manuscript with recommended physiotherapy interventions was prepared based on currently available evidence as presented and agreed upon by expert consensus. Findings: Experts recommended the following interventions based on mean agreement scores: diaphragmatic breathing (Mean = 7.5), thoracic expansion (with shoulder elevation) (Mean =8.5) and expiratory muscle training (Mean=6.3) for respiratory rehabilitation. Mild to moderate graded exercise (Mean= 7.7) was suggested for recovery from fatigue and McKenzie directional preference exercises for low back pain (Mean= 8.6), neck pain (Mean =7.9) and knee pain (Mean =8.3).

A simple and low power standalone photovoltaic (PV) water pumping system with conventional centrifugal pump is presented here. The system uses a DC-DC boost converter which extract the maximum power from the solar array and a Sine Pulse Width Modulation (SPWM) technique based Voltage Source Inverter (VSI) for DC-AC conversion. The DC link voltage is controlled by varying pump speed to match the available solar power to pump power. The proposed control scheme requires no additional current and speed sensor. The simulation is performed in MATLAB/SIMULINK under different radiation condition. The simulation results show that the pump can run under low radiation and can fill up a 1000 liter tank within the average sun hours.

The objective of the study was to explore the effectiveness of McKenzie Manipulative Therapy (MMT) for patients with LDH. Methodology: This was an assessor blinded, 36-month RCT, at Center for Rehabilitation of the Paralyzed (CRP) in Savaar, Bangladesh. Seventy-two subjects, ages 28-47 years and clinically diagnosed with MRI findings of LDH, were randomly recruited from hospital records and sixty-eight found eligible. The control group received stretching exercise and graded oscillatory mobilization, and the experimental group received McKenzie manipulative therapy for 12 sessions in 4 weeks, both groups received a standard set of care also. The pain was the primary outcome and the secondary outcome was participation in functional activities and disability. Results: Pain and Disability found significant improvement in both groups, with the McKenzie approach significantly superior to the control group (p Conclusion: The McKenzie manipulative therapy approach was found to be effective for pain, disability and participation in activities for single or multiple level LDH patients in a short time from day 1 to week 4, and the treatment effect extends after 6 months. Clinical Trial Registration No.: CTRI/2020/ 04/024667.

This study aimed to explore the magnitude and determinants of health care seeking behaviors for common infectious disease and malnutrition among Bangladeshi under-five children living in slum areas. A cross-sectional study of 300 children-caregiver dyads was conducted in an urban slum of Bangladesh. Data were collected via a structured questionnaire with accompanying anthropometric assessments of children administered by research staff. Multiple logistic regression was employed to identify associated factors of health care seeking behaviors. Only 44.7% and 13.0% of respondents sought care for childhood infectious diseases and malnutrition, respectively. Being a male child, 2–5 years old, having ≤5 family members, monthly family income >125$, and living in close proximity to a health facility were found to be potential determinants of health care seeking behavior for childhood infectious diseases. Mother/caregivers with poor nutritional information knowledge and who had a child 2–5 years old reported engaging in less care seeking behaviors regarding their child’s malnutrition compared to their counterparts. Caregivers of children under the age of 5 years old reported low participation in health care seeking behaviors in relation to childhood infectious disease and malnutrition. Families living in slums require additional support targeting health and nutritional educational programs.

Diarrhea causes major childhood morbidity and mortality globally. This study aimed to investigate the prevalence and associated factors of childhood diarrhea among under-five children in Southern coastal area of Bangladesh. A community-based cross-sectional study conducted from April to June 2018 among 202 randomly selected children. A structured questionnaire used to collect information on a three month diseases occurrence and other covariates. The association of diarrhea with socio economy, personal and food hygiene practices observed using multivariate logistic regression after adjusting for potential confounders. Prevalence of childhood diarrhea was 10.9%. In bivariate analysis, mother’s education, family income, father’s occupation, hand washing of child before feeding and refrigerator associated with outcomes. In multivariate analysis, father’s occupation, hand washing of child by soap before feeding and having refrigerator in households was associated with childhood diarrhea after controlling the socio-demographic factors (age and gender). Child of unemployed fathers were more likely to have diarrhea than employed father (AOR=0.206; 95% CI: 0.070-0.610).Child do not wash hand before feeding (AOR=0.393; 95% CI =0.102-0.511) and households not having refrigerator (AOR= 0.072; 95% CI: 0.007-0.745) had higher odds of diarrhea. The load of diarrhea in this setting was almost double to the national rate. Poor hand washing of child and refrigerator are major risk factor high burden of the disease. Health promotion strategies on proper food storage and child feeding practices are recommended for the prevention of childhood diarrhea. Asian Australas. J. Food Saf. Secur. 2018, 2(2), 93-99
