Prevalence of diabetes and prediabetes and their risk factors among Bangladeshi adults: a nationwide survey

OBJECTIVE To estimate the prevalence of diabetes and prediabetes in Bangladesh using national survey data and to identify risk factors. METHODS Sociodemographic and anthropometric data and data on blood pressure and blood glucose levels were obtained for 7541 adults aged 35 years or more from the biomarker sample of the 2011 Bangladesh Demographic and Health Survey (DHS), which was a nationally representative survey with a stratified, multistage, cluster sampling design. Risk factors for diabetes and prediabetes were identified using multilevel logistic regression models, with adjustment for clustering within households and communities. FINDINGS The overall age-adjusted prevalence of diabetes and prediabetes was 9.7% and 22.4%, respectively. Among urban residents, the age-adjusted prevalence of diabetes was 15.2% compared with 8.3% among rural residents. In total, 56.0% of diabetics were not aware they had the condition and only 39.5% were receiving treatment regularly. The likelihood of diabetes in individuals aged 55 to 59 years was almost double that in those aged 35 to 39 years. Study participants from the richest households were more likely to have diabetes than those from the poorest. In addition, the likelihood of diabetes was also significantly associated with educational level, body weight and the presence of hypertension. The prevalence of diabetes varied significantly with region of residence. CONCLUSION Almost one in ten adults in Bangladesh was found to have diabetes, which has recently become a major public health issue. Urgent action is needed to counter the rise in diabetes through better detection, awareness, prevention and treatment.

Health-Related Financial Catastrophe, Inequality and Chronic Illness in Bangladesh

Background Bangladesh has a high proportion of households incurring catastrophic health expenditure, and very limited risk sharing mechanisms. Identifying determinants of out-of-pocket (OOP) payments and catastrophic health expenditure may reveal opportunities to reduce costs and protect households from financial risk. Objective This study investigates the determinants of high healthcare expenditure and healthcare- related financial catastrophe. Methods A cross-sectional household survey was conducted in Rajshahi city, Bangladesh, in 2011. Catastrophic health expenditure was estimated separately based on capacity to pay and proportion of non-food expenditure. Determinants of OOP payments and financial catastrophe were estimated using double hurdle and Poisson regression models respectively. Results On average households spent 11% of their total budgets on health, half the residents spent 7% of the monthly per capita consumption expenditure for one illness, and nearly 9% of households faced financial catastrophe. The poorest households spent less on health but had a four times higher risk of catastrophe than the richest households. The risk of financial catastrophe and the level of OOP payments were higher for users of inpatient, outpatient public and private facilities respectively compared to using self-medication or traditional healers. Other determinants of OOP payments and catastrophic expenses were economic status, presence of chronic illness in the household, and illness among children and adults. Conclusion Households that received inpatient or outpatient private care experienced the highest burden of health expenditure. The poorest members of the community also face large, often catastrophic expenses. Chronic illness management is crucial to reducing the total burden of disease in a household and its associated increased risk of level of OOP payments and catastrophic expenses. Households can only be protected from these situations by reducing the health systems dependency on OOP payments and providing more financial risk protection.

Reducing ambulance response times using geospatial-time analysis of ambulance deployment.

OBJECTIVES This study aimed to determine if a deployment strategy based on geospatial-time analysis is able to reduce ambulance response times for out-of-hospital cardiac arrests (OOHCA) in an urban emergency medical services (EMS) system. METHODS An observational prospective study examining geographic locations of all OOHCA in Singapore was conducted. Locations of cardiac arrests were spot-mapped using a geographic information system (GIS). A progressive strategy of satellite ambulance deployment was implemented, increasing ambulance bases from 17 to 32 locations. Variation in ambulance deployment according to demand, based on time of day, was also implemented. The total number of ambulances and crews remained constant over the study period. The main outcome measure was ambulance response times. RESULTS From October 1, 2001, to October 14, 2004, a total of 2,428 OOHCA patients were enrolled into the study. Mean ± SD age for arrests was 60.6 ± 19.3 years with 68.0% male. The overall return of spontaneous circulation (ROSC) rate was 17.2% and survival to discharge rate was 1.6%. Response time decreased significantly as the number of fire stations/fire posts increased (Pearson χ(2) = 108.70, df = 48, p < 0.001). Response times for OOHCA decreased from a monthly median of 10.1 minutes at the beginning to 7.1 minutes at the end of the study. Similarly, the proportion of cases with response times < 8 minutes increased from 22.3% to 47.3% and < 11 minutes from 57.6% to 77.5% at the end of the study. CONCLUSIONS A simple, relatively low-cost ambulance deployment strategy was associated with significantly reduced response times for OOHCA. Geospatial-time analysis can be a useful tool for EMS providers.

Nationwide Survey of Prevalence and Risk Factors for Diabetes and Prediabetes in Bangladeshi Adults

Diabetes is a major noncommunicable disease, ranking as a leading cause of death and disability worldwide (1). Globally, the prevalence of diabetes is ∼8%, and nearly 80% of patients with diabetes live in low- and middle-income countries (2). Like many developing countries, prevalence of diabetes in Bangladesh increased substantially from 4% in 1990 to 10% in 2011 and is projected to reach 13% by 2030 (3,4). Despite this heavy burden, currently there are no epidemiologic studies in Bangladesh that investigate prevalence of diabetes and risk factors using nationally representative data. Therefore, we estimated the prevalence of diabetes and prediabetes and identified associated risk factors using Bangladesh nationwide survey data by multilevel logistic regression models. Our analysis was based on the 2011 Bangladesh Demographic and Health Survey. Data were available as of February 2013, including 8,835 residents (4,524 men and 4,311 women) aged …

Implications for public access defibrillation placement by non-traumatic out-of-hospital cardiac arrest occurrence in Singapore

The American Heart Association recommends automated external defibrillator placement in public areas with a high probability (>1) of out‐of‐hospital cardiac arrest (OHCA) occurring in 5 years. We aimed to determine the incidence rate of OHCA for different location categories in Singapore.

Prehospital delay in patients presenting with acute ST-elevation myocardial infarction.

To characterize prehospital delays in patients presenting with acute ST-elevation myocardial infarction to the emergency department of a tertiary hospital in Asia. A retrospective review of 273 patients with diagnosis of ST-elevation myocardial infarction; symptom to door (S2D) time was described in two ways, time from first onset of symptoms; and time from the onset of the worst episode to presentation at emergency department. The median first onset S2D time was 173 min (interquartile range 80–350 min); and median worst episode S2D time was 131 min (interquartile range 70–261 min). Patients with prehospital delay tended to use their own transport compared with the no delay group (P=0.026, 95% confidence interval=0.02–0.24). There was no difference in S2D times for typical compared with atypical symptoms. A large proportion of patients experienced delay in seeking medical care after the onset of acute coronary symptoms. Self-transport was associated with delay.

Trend, projection, and appropriate body mass index cut-off point for diabetes and hypertension in Bangladesh

BACKGROUND Rapid increasing of high body mass index (BMI) is a global health concern. Population with high BMI predicts an increased risk of diabetes and hypertension. The objective of the present study is to estimate the trend and prediction of diabetes and hypertension in Bangladesh, to examine the association of BMI with risk of diabetes and hypertension, and to ascertain an appropriate BMI cut-off point for screening diabetes. METHODS We searched PubMed from inception to August 2016 and identified studies reporting diabetes and hypertension prevalence in Bangladesh. Bangladesh Demographic and Health Survey 2011 data was also included in this study. Bayesian model was used to estimate trend and projection in diabetes and hypertension prevalence by sex and residence. Receiver operating characteristic curves was used to determine the optimal BMI cut-off point for screening diabetes. FINDINGS Of 535 articles reviewed, 35 studies reported prevalence of diabetes and hypertension. Prevalence of diabetes (95% credible interval) increased between 1992 and 2015 from 3.2% (2.2-4.3) to 12.1% (9.1-15.4) in men, and from 2.5% (1.8-3.5) to 13.4% (9.7-17.6) in women. Diabetes prevalence in 2030 is expected to reach 23.6% (13.6-36.3) for men and 33.5% (19.9-50.9) for women. Hypertension prevalence increased between 1992 and 2015 from 11.0% (8.6-13.7) to 20.4% (18.4-22.4%) in 2015 in men, and from 14.0% (10.3-19.0) to 21.3% (19.0-23.6) in women. Annual average rate of change for diabetes prevalence was higher among women and in rural areas, while for hypertension prevalence it was higher in men and urban areas. Adults with BMI of 22.5kg/m2 or above had a higher risk of diabetes and hypertension in this study. The optimal BMI cut-off point for screening diabetes was 23kg/m2 for overall population, 22kg/m2 for men, and 23kg/m2 for women. INTERPRETATION Diabetes is more prevalent among women and rural population groups, while hypertension is more prevalent among men and urban population groups in Bangladesh. A BMI of 22.5kg/m2 or more is risk factors for developing diabetes and hypertension. Screening for diabetes may be considered for all Bangladeshi adults with a BMI of ⩾23kg/m2.

Inequalities in financial risk protection in Bangladesh: an assessment of universal health coverage

BackgroundFinancial risk protection and equity are major components of universal health coverage (UHC), which is defined as ensuring access to health services for all citizens without any undue financial burden. We investigated progress towards UHC financial risk indicators and assessed variability of inequalities in financial risk protection indicators by wealth quintile. We further examined the determinants of different financial hardship indicators related to healthcare costs.MethodsA cross-sectional, three-stage probability survey was conducted in Bangladesh, which collected information from 1600 households from August to November 2011. Catastrophic health payments, impoverishment, and distress financing (borrowing or selling assets) were treated as financial hardship indicators in UHC. Poisson regression models were used to identify the determinants of catastrophic payment, impoverishment and distress financing separately. Slope, relative and concentration indices of inequalities were used to assess wealth-based inequalities in financial hardship indicators.ResultsThe study found that around 9% of households incurred catastrophic payments, 7% faced distress financing, and 6% experienced impoverishing health payments in Bangladesh. Slope index of inequality indicated that the incidence of catastrophic health payment and distress financing among the richest households were 12 and 9 percentage points lower than the poorest households respectively. Multivariable Poisson regression models revealed that all UHC financial hardship indicators were significantly higher among household that had members who received inpatient care or were in the poorest quintile. The presence of a member with chronic illness in a household increased the risk of impoverishment by nearly double.ConclusionThis study identified a greater inequality in UHC financial hardship indicators. Rich households in Bangladesh were facing disproportionately less financial hardship than the poor ones. Households can be protected from financial hardship associated with healthcare costs by implementing risk pooling mechanism, increasing GDP spending on health, and properly monitoring subsidized programs in public health facilities.

Knowledge and attitudes towards cardiopulmonary resuscitation and defibrillation amongst Asian primary health care physicians.

Objective To assess the knowledge and attitudes of local primary health care physicians in relation to cardiopulmonary resuscitation (CPR) and defibrillation. Methods We conducted a survey on general practitioners in Singapore by using a self-administered questionnaire that comprised 29 questions. Results The response rate was 80%, with 60 of 75 physicians completing the questionnaire. The average age of the respondents was 52 years. Sixty percent of them reported that they knew how to operate an automated external defibrillator (AED), and 38% had attended AED training. Only 36% were willing to perform mouth-to-mouth ventilation during CPR, and 53% preferred chest compression-only resuscitation (CCR) to standard CPR. We found those aged <50 years were more likely to be trained in basic cardiac life support (BCLS) (P < 0.001) and advanced cardiac life support (P = 0.005) or to have ever attended to a patient with cardiac arrest (P = 0.007). Female physicians tended to agree that all clinics should have AEDs (P = 0.005) and support legislation to make AEDs compulsory in clinics (P < 0.001). We also found that a large proportion of physicians who were trained in BCLS (P = 0.006) were willing to perform mouth-to-mouth ventilation. Conclusion Most local primary care physicians realize the importance of defibrillation, and the majority prefer CCR to standard CPR.

Tobacco control policies to promote awareness and smoke-free environments in residence and workplace to reduce passive tobacco smoking in Bangladesh and its correlates

Background Bangladesh is one of the highest tobacco consuming countries in the world, with reported 21.2% of the population as daily smokers, 24.3% as smokeless tobacco users, and 36.3% as adult passive smoker. Given the high prevalence and established harmful effects of passive tobacco smoking, this study aimed to estimate of pattern of smoking policies in residential and work place, and to identify the associated socio-economic and demographic correlates in Bangladesh. Data and methods Secondary data of sample size 9629 collected by the Global Adult Tobacco Survey (GATS) 2010 has been used. Along with descriptive analysis, binary logistic regression model has been used to analyze the socio-demographic and economic correlates to tobacco smoking policy. Results The prevalence of male and female passive tobacco smokers was 74.3% and 25.8% respectively. Among the passive tobacco smokers, 22.2% reported that smoking was allowed at their home and 29.8% reported that there was no such smoking policy at their home. Alternatively, 26.0% passive tobacco smokers reported that smoking was allowed and 27.5% reported that there was no such smoking policy at their work place. Logistic regression analysis indicated that for tobacco smokers group, the odds of allowing smoking at home was 4.85 times higher than the non-smoker respondent (OR = 4.85, 95% CI = 4.13, 5.71), 1.18 times more likely to be allowed at home in rural areas than urban areas (OR = 1.18, 95% CI = 1.06,1.32) and less for college/university completed and (or) higher educated respondent than no formal schooling (OR = 0.35, 95% CI = 0.24, 0.52). On the other hand, smoking was 1.70 times more likely to be allowed at work place for tobacco smokers than their counter part respondent (OR = 1.70, 95% CI = 1.36, 2.14) and was less likely to be allowed for college/university completed and (or) higher educated respondent (OR = 0.26, 95% CI = 0.14, 0.45) than respondent with no formal schooling. Conclusion To reduce the passive smoking, lower educated people and people in urban areas should advocate more about the adverse effect of active and passive tobacco smoking. Also, smoking policy should reform introducing smoking zone at work places and residential buildings.
