Rising prevalence of type 2 diabetes in rural Bangladesh: a population based study.

The aim of the study was to determine the temporal changes in the prevalence of type 2 diabetes mellitus and its associated risk factors in a rural population of Bangladesh. A total of 4757 subjects age >/=20 years both male and female were enrolled randomly in a cross-sectional study in 1999. The same area and population was reinvestigated in 2004 following the same selection procedure, on a sample of 3981 individuals. Structural and economical changes were noted for the last 5 years in the locality. An increased prevalence of diabetes was found with 6.8% in the present survey compared with 2.3% in the earlier survey (p<0.05). Age, BMI and systolic blood pressure were found to be significant risk factors following both for FBG and for OGTT. WHR was found to be a significant risk factor for men only. A substantial agreement was observed between FBG and OGTT (kappa 0.63) compared to the previous investigation in 1999 (kappa 0.40). Differences in the indices of obesity, that is BMI, WHR and waist girth, may in part explain the increased prevalence, which in turn may explain due to fast-expanded urbanization. The state of affairs warrants immediate measures necessary to prevent the epidemic particularly in the localities that are in the transition phase from rural to semi-urban facilities.

Type 2 diabetes and impaired fasting blood glucose in rural Bangladesh: a population-based study.

BACKGROUND: Diabetes is a fast expanding global health problem but more so in the developing countries. Therefore, it is of particular interest to study the epidemiological transition of the state and to identify the risk factors in order to recognize the extent of the problem. METHODS: A random sample of 5000 rural individuals (age >/=20 years) were included in a cross-sectional study. Fasting capillary blood glucose levels were measured from 4757 individuals. Height, weight, waist, hips including blood pressure and demographic information was collected. RESULTS: The study population was lean [mean body mass index (BMI) 19.4] with a low prevalence of type 2 diabetes but relatively high impaired fasting glucose. No relationship between type 2 diabetes and BMI in men, but an overall relationship was observed for women (P = 0.04) (data not shown). Age, sex, and waist/hip ratio appeared to be important risk factors for the occurrence of type 2 diabetes in this population. CONCLUSIONS: Low prevalence of type 2 diabetes and relative high impaired fasting blood glucose was observed. The factors associated with the occurrence of diabetes in this population appeared to differ than its known relations with BMI. This may indicate that the risk factors for type 2 diabetes are likely to differ in different population. Our results are likely to be in line with the Indian data suggesting that a revised guideline for anthropometric measures in the South Asian population is called for, in order to classify people at risk.

Type 2 diabetes in rural and urban population: diverse prevalence and associated risk factors in Bangladesh.

AIMS: To describe differences in prevalence of Type 2 diabetes mellitus with its associated risk factors between rural and urban populations in Bangladesh. Diagnostic criteria [fasting blood glucose (FBG) and oral glucose tolerance tests (OGTT)] were compared and reviewed for both populations. METHODS: A total of 1555 subjects from urban and 4757 from rural communities (age > or = 20 years) with similar cultural and ethnic backgrounds were randomly selected in a cross-sectional survey. FBG values were determined from all and 2-h post-glucose capillary blood samples were determined after a 75-g oral glucose load for a selected number (urban 476, rural 1046). RESULTS: A higher prevalence of diabetes was found in urban (8.1%) compared with rural populations (2.3%). Age, sex and waist-to-hip ratio for men were significant risk factors for both urban and rural subjects following fasting and 2-h post-glucose values adjusted for a number of confounding variables. Poor agreement was observed between FBG and OGTT for both urban (kappa 0.41) and rural (kappa 0.40) areas. CONCLUSIONS: A higher prevalence of diabetes mellitus (DM) in the urban population was observed compared with rural subjects despite similar body mass indexes (BMI). Differences in obesity, waist/hip ratio or hypertension failed to explain the increasing occurrence of T2DM in the urban population.

Diabetes and hypertension in pregnancy in a rural community of Bangladesh: a population-based study.

AIMS: Gestational diabetes mellitus (GDM) is associated with increased infant mortality. Diabetes and infant mortality is higher in Bangladesh but the prevalence of diabetes and hypertension in pregnancy is not known. Thus, this study addressed the prevalence of diabetes and hypertension in pregnancy. METHODS: We selected 10 villages randomly in a union council of Nandail subdistrict. Following a population census (n = 14 382: male/female = 7476/6906) on demography and marital status, we interviewed 2205 married women (18-44 years) for detection of pregnancy. Of a total of 172 pregnancies, we investigated 147 with a gestational age of 24-28 weeks for obstetrical history, clinical examination and blood pressure (BP). Fasting (FBG) and 2-h blood glucose (2hBG) were assessed by Hemocue cuvette. WHO diagnostic criteria were used. RESULTS: The overall prevalence (95% CI) of diabetes was 6.8% (1.88-9.32) and 8.2% (3.74-12.64) according to FBG and 2hBG, respectively. The crude prevalence of systolic and diastolic hypertension was 6.8 and 5.4%, respectively. The median (interquartile range) values for age, BMI and FBG of the participants were 25.0 (21.0-30.0) years, 19.5 (18.2-21.2) and 3.9 (3.6-4.3), respectively. The history of abortion, neonatal death and stillbirth was found in 19.9, 11.4 and 9.6%, respectively. The prevalence of GDM was higher among those with the history of stillbirth (15.4 vs. 6.0%) and neonatal death (11.8 vs. 6.2%) than those without. CONCLUSION: The prevalence of GDM in rural Bangladesh is comparable with any other population with higher prevalence of GDM. Increased morbidity and mortality among mothers and newborns in Bangladesh may, in part, be because of increased prevalence of GDM.

Antidiabetic activity of Caesalpinia bonducella F. in chronic type 2 diabetic model in Long-Evans rats and evaluation of insulin secretagogue property of its fractions on isolated islets.

Caesalpinia bonducella F., is a shrub widely distributed throughout the coastal region of India and is ethnically used by the tribal people of Andaman and Nicober Island as a remedy of symptoms of diabetes mellitus. This ethnic report prompted the detail investigation of hypoglycemic activity of Caesalpinia bonducella seeds, initially on physiological hyperglycemic model and then on type 1 and type 2 sub-acute diabetic animal models which has already been reported. Evaluation of different extracts from Caesalpinia bonducella in chronic type 2 diabetic model alongwith insulin secretagogue activity of five fractions isolated from the Caesalpinia bonducella seed kernel are presented in this paper. Both the aqueous and ethanolic extracts showed potent hypoglycemic activity in chronic type 2 diabetic model. Two fractions BM 169 and BM 170 B could increase secretion of insulin from isolated islets.

Diabetes mellitus in Tropical Chronic Pancreatitis Is Not Just a Secondary Type of Diabetes.

AIMS: In chronic calcific pancreatitis of the tropics, etiology and relationship to developing diabetes mellitus are unknown. Some consider these cases a straightforward secondary type of diabetes, while others suggest selective beta-cell impairment. Testing pancreatic function, we investigated whether selective beta-cell impairment triggers diabetes associated with tropical pancreatitis. METHODS: At a Bangladeshi research institute, 8 chronic tropical pancreatitis and no diabetes mellitus subjects, 14 fibrocalculous pancreatic diabetics and 27 matched healthy controls underwent arginine (endocrine pancreatic function) and secretin (exocrine pancreatic function assessment) stimulation tests. RESULTS: All patients with clinically-diagnosed, chronic pancreatitis demonstrated pronounced exocrine pancreatic dysfunction with beta-cell functioning differing significantly between the two groups. Compared to controls, patients having tropical pancreatitis and no diabetes showed normal plasma C-peptide values at baseline and after arginine stimulation, while fibrocalculous pancreatic diabetics demonstrated a typical diabetic pattern for plasma C-peptide levels. In contrast, pancreatic alpha-cell functioning (glucagon response to arginine) was preserved in both pancreatitis groups. CONCLUSION: A preserved pancreatic alpha-cell function in diabetics with advanced chronic pancreatitis of the tropics supports the concept of two different pathogenic mechanisms, one eliciting chronic pancreatitis and the other selective pancreatic beta-cell impairment and subsequent diabetes mellitus.

Acetylation phenotype status in a Bangladeshi population and its comparison with that of other Asian population data.

The objective of the present study was to determine the acetylator status of the Bangladeshi population and to compare the findings with the acetylator status of other Asian populations. The acetylator phenotype was determined in 517 unrelated healthy Bangladeshi subjects. The phenotyping procedure was done according to Price Evans' method using the NAT2 specific probe drug--sulphadimidine. The Bangladeshi population showed a bimodal distribution of fast and slow acetylators. Of a total of 517 healthy Bangladeshi, 79.5% (n=411) were fast acetylators and the rest 20.5% (n=106) were slow acetylators. The high frequency of the fast acetylators in the population of Bangladesh was comparable to other populations in East Asia. When this acetylator status was compared with other Asian data, the Asian population showed a positive correlation between the acetylator status and the geographical longitude (r=0.919; t=7.37; p>0.001; d.f.=10). The regression line of the scatter diagram showed that the frequency of acetylating capacity increasingly occurred in the populations towards eastern Asia (regression coefficient=0.54; constant=52.36). This line was termed as the Asian fast acetylator longitude (AFAL). Thus the AFAL was able to predict the acetylator status of the Asian population by the east-west geographical longitude. The AFAL could be a useful prognosticator in the disposition for the effective and safe use of numerous drugs and xenobiotic compounds in humans.

Diabetes and impaired fasting glycemia in the tribes of Khagrachari hill tracts of Bangladesh.

OBJECTIVE: To determine the prevalence of type 2 diabetes and impaired fasting glycemia (IFG) in a tribal population of Bangladesh. RESEARCH DESIGN AND METHODS: A cluster sampling of 1,287 tribal subjects of age > or =20 years was investigated. They live in a hilly area of Khagrachari in the far northeast of Bangladesh. Fasting plasma glucose, blood pressure, height, weight, waist girth, and hip girth were measured. Lipid fractions were also estimated. We used the 1997 American Diabetes Association diagnostic criteria. RESULTS: The crude prevalence of type 2 diabetes was 6.6% and IFG was 8.5%. The age-standardized (20-70 years) prevalence of type 2 diabetes (95% CI) was 6.4% (4.96-7.87) and of IFG was 8.4% (6.48-10.37). Both tribesmen and women had equal risk for diabetes and IFG. Compared with the lower-income group, the participants with higher income had a significantly higher prevalence of type 2 diabetes (18.8 vs. 3.1%, P < 0.001) and IFG (17.2 vs. 4.3%, P < 0.001). Using logistic regression, we found that increased age, high-income group, and increased central obesity were the important risk factors of diabetes. CONCLUSIONS: The prevalence of diabetes in the tribal population was higher than that of the nontribal population of Bangladesh. Older age, higher central obesity, and higher income were proven significant risk factors of diabetes. High prevalence of diabetes among these tribes indicates that the prevalence of diabetes and its complications will continue to increase. Evidently, health professionals and planners should initiate diabetes care in these tribal communities.

Comparison between IS6110 and MPB64 primers for the diagnosis of Mycobacterium tuberculosis in Bangladesh by polymerase chain reaction (PCR).

The study was carried out to evaluate the efficacy of two different primers in PCR based diagnosis of tuberculosis on the basis of the time involvement, steps of PCR, cost and accuracy of results. Among 17 clinically suspected pulmonary tuberculosis patient's (M:F 65:35) sputum samples, 12 were found positive by both primers. Among 81 routine samples (sputum = 12; blood = 27; cerebrospinal fluid = 16; ascitic fluid = 12 and urine = 14), 12 were found to be positive by IS6110 primer while 13 were found positive by MPB64. The result of M. tuberculosis DNA PCR in sputum, ascitic fluid, CSF and urine samples were found to be similar in both the primers used. It is suggested that, M. tuberculosis DNA PCR in blood samples using MPB64 primers sometime gives false positive result and therefore, may not be recommended for blood samples. As in other samples both the primers gave almost the same result and therefore, both the primers can be used for MTB DNA PCR vice versa in order to cross check if one gives dubious result.

Fasting cut-offs in determining the prevalence of diabetes and intermediate glucose abnormality in a non-obese population.

The study was undertaken to compare the effect of ADA and WHO criteria for screening of diabetes mellitus (DM) and intermediate glucose abnormality (Impaired fasting glucose/Impaired glucose tolerance-IFG/IGT) and to explore an acceptable fasting cut-off in a population-based study. Ten suburb villages with a population of 11,895 were selected purposively. Of the total 6235 eligible (> or = 20y) subjects, 4144 volunteered. We took height, weight, hip- and waist-girth, blood pressure and fasting blood glucose (FBG). All participants were classified into Group-1 (Gr-1: n=453) and Group-2 (Gr-2: n=3691), based on FBG above and below 5.4 mmol/l, respectively. All from Gr-1 and 610 randomized subjects from Gr-2 were investigated for oral glucose tolerance test (OGTT), HbA1c and lipids. The mean (SD) of age, body mass index (BMI) and FBG of all participants was 37.6 (15.2) y, 19.4 (2.9), and 4.7 (0.9) mmol/l, respectively. The prevalence of diabetes and IFG/IGT using American Diabetes Association (ADA) criteria were compared with WHO criteria separately in Gr-1 and Gr-2. For group-1, ADA criteria could diagnose 5.9% as diabetes and 2.1% as IFG, whereas, WHO criteria diagnosed 11.5% diabetes and 19% IGT. Likewise, in Gr-2, ADA detected much less than WHO criteria (DM: 0.3 vs. 2.3%; IFG/IGT 1.0 vs. 14.6%). We compared fasting and 2 hours post-load glucose (2-hBG) values according to percentiles. We found that 11.1 of 2-hBG corresponded with a fasting value that lies between 90 to 95th percentile, equivalent to 5.1-5.7 mmol/l. Using receiver operating characteristics (ROC) curve, we determined the cut-offs 4.6 - 5.4 mmol/l for IFG and > or = 5.5 for diabetes. Taking age and BMI into account the kappa agreements were better between the estimated cut-offs and the given 2-hBG values. The ADA cut-offs were found ineffective for screening. We proposed the modified fasting cut-offs for screening IFG and diabetes among the non-obese population.

Advanced studies on the hypoglycemic effect of Caesalpinia bonducella F. in type 1 and 2 diabetes in Long Evans rats.

Caesalpinia bonducella, widely distributed throughout the coastal region of India and used ethnically by the tribal people of India for controlling blood sugar was earlier reported by us to possess hypoglycemic activity in animal model. This prompted us to undertake a detail study with the aqueous and ethanolic extracts of the seeds of this plant in both type 1 and 2 diabetes mellitus in Long Evans rats. Significant blood sugar lowering effect (P < 0.05) of C. bonducella was observed in type 2 diabetic model. Special emphasis was given on the mechanistic study by gut absorption of glucose and liver glycogen.

Effect of soluble dietary fibre fraction of Trigonella foenum graecum on glycemic, insulinemic, lipidemic and platelet aggregation status of Type 2 diabetic model rats.

The soluble dietary fibre (SDF) fraction of Trigonella foenum graecum (Tf-sdf) has previously been shown to reduce postprandial elevation in blood glucose level of Type 2 model diabetic rats by delaying the digestion of sucrose. The Tf-sdf has now been investigated for its chronic effect on serum fructosamine, insulin and lipid levels, and on platelet aggregation in Type 2 diabetic rats. Tf-sdf was administered orally twice daily at a dose of 0.5 g kg(-1) for 28 days. It lowered the serum fructosamine level (P<0.05) with no significant change in the insulin level as compared with the control. Atherogenic lipids, i.e. triglycerides, cholesterol and LDL-cholesterol were found to decrease significantly in Tf-sdf fed rats (P<0.01). HDL-cholesterol showed an opposite trend (P=0.024), but serum non-esterified fatty acid (NEFA) values paralleled the atherogenic lipids (P=0.001). No significant effect on platelet aggregation (%) was found although there was a tendency to lower the aggregation (P=0.069). It is concluded that Tf-sdf has a beneficial effect on dyslipidemia and has a tendency to inhibit platelet aggregation in Type 2 model diabetic rats.

Diabetes and impaired fasting glycemia in a rural population of Bangladesh.

OBJECTIVE: To determine the prevalence of type 2 diabetes and impaired fasting glycemia (IFG) in a rural population of Bangladesh. RESEARCH DESIGN AND METHODS: A cluster sampling of 4,923 subjects >/=20 years old in a rural community were investigated. Fasting plasma glucose, blood pressure, height, weight, and girth of waist and hip were measured. BMI and waist-to-hip ratio (WHR) were calculated. Total cholesterol, triglycerides, and HDL cholesterol were also estimated. We used the 1997 American Diabetes Association diagnostic criteria. RESULTS: The crude prevalence of type 2 diabetes was 4.3% and IFG was 12.4%. The age-standardized prevalence of type 2 diabetes (95% CI) was 3.8% (3.12-4.49) and IFG was 13.0% (11.76-14.16). The subjects with higher family income had significantly higher prevalence of type 2 diabetes (5.9 vs. 3.5%, P < 0.001) and IFG (15.6 vs. 10.8%, P < 0.001) than those with lower income. Employing logistic regression in different models, we found that wealthy class, family history of diabetes, reduced physical exercise, and increased age, BMI, and WHR were the important predictors of diabetes. Total cholesterol, triglycerides, and HDL cholesterol showed no association with diabetes and IFG. CONCLUSIONS: The prevalence of diabetes and IFG in the rural population was found to be on the increase compared with the previous reports of Bangladesh and other Asian studies. Older age, higher obesity, higher income, family history of diabetes, and reduced physical activity were proved significant risk factors for diabetes and IFG, whereas plasma lipids showed no association with diabetes and IFG. Further study may address whether diabetes is causally associated with insulin deficiency or insulin resistance.

Waist-to-height ratio is a better obesity index than body mass index and waist-to-hip ratio for predicting diabetes, hypertension and lipidemia.

Body mass index (BMI, kg/m.sq) and waist-to-hip ratio (WHR) are widely used as obesity indices for diabetes and cardiovascular risks. Lower adult height was related to diabetes and stroke. Waist-girth was proved important for visceral obesity. Incorporating waist-girth and height as waist-to-height ratio (WHtR), we reported earlier--"Waist-to-height ratio is an important predictor of hypertension and diabetes". We readdressed this index in a larger sample with two-sample OGTT and lipid profiles. In a cluster sampling of 16,818 rural inhabitants, considering age > or = 20 y, 5713 subjects were found eligible. Of them, 4923 (M/F=2321/2602) volunteered for height, weight, blood pressure, waist-girth and hip-girth. Fasting venous blood (5 ml) was drawn for plasma glucose, total cholesterol (T-chol), Triglycerides (TG) and high-density lipoprotien (HDL-c). Overall, 1565 participants were undertaken for OGTT. The mean (SD) values of BMI, WHR and WHtR for subjects with diabetes and hypertension were significantly higher in either sex. The level significance was highest for WHtR. The prevalence of diabetes and hypertension increased significantly with higher quintiles of BMI, WHR and WHtR (chi sq values were largest in WHtR for both events). Partial correlation coefficients, controlling for age and sex, showed that BMI, WHR and WHtR significantly correlated with systolic and diastolic BP, FBG, T-chol and TG. In the entire correlation matrix, the 'r' values were the highest for WHtR. Taking diabetes and hypertension as dependent variables, logistic regression also showed the highest odds ratio in higher WHtR than BMI and WHR. We conclude that WHtR was proved again a valuable obesity index for predicting diabetes, hypertension and lipidemia.

SPINK1 is a susceptibility gene for fibrocalculous pancreatic diabetes in subjects from the Indian subcontinent.

Fibrocalculous pancreatic diabetes (FCPD) is a secondary cause of diabetes due to chronic pancreatitis. Since the N34S variant of the SPINK1 trypsin inhibitor gene has been found to partially account for genetic susceptibility to chronic pancreatitis, we used a family-based and case-control approach in two separate ethnic groups from the Indian subcontinent, to determine whether N34S was associated with susceptibility to FCPD. Clear excess transmission of SPINK1 N34S to the probands with FCPD in 69 Bangladeshi families was observed (P<.0001; 20 transmissions and 2 nontransmissions). In the total study group (Bangladeshi and southern Indian) the N34S variant was present in 33% of 180 subjects with FCPD, 4.4% of 861 nondiabetic subjects (odds ratio 10.8; P<.0001 compared with FCPD), 3.7% of 219 subjects with type 2 diabetes, and 10.6% of 354 subjects with early-onset diabetes (aged <30 years) (P=.02 compared with the ethnically matched control group). These results suggest that the N34S variant of SPINK1 is a susceptibility gene for FCPD in the Indian subcontinent, although, by itself, it is not sufficient to cause disease.

Genetic susceptibility to fibrocalculous pancreatic diabetes in Bangladeshi subjects: a family study.

Fibrocalculous pancreatic diabetes (FCPD) is an uncommon cause of diabetes, seen mainly in developing countries. A family-based study was carried out in 67 Bangladeshi families, consisting of a proband with FCPD and both parents, to determine whether an association exists between FCPD susceptibility and either the major histocompatiblity complex (MHC) or insulin gene (INS) loci. HLA-DQB1 typing was done using allele-specific primers, and INS was typed using the restriction enzyme HphI. Three microsatellites (TNFa, TNFc and TNFd), from within and flanking the TNF-LT locus, were used for MHC Class IV typing and a PCR-RFLP assay was used to define the -308G/A TNF promoter polymorphism. The extended transmission disequilibrium test (ETDT) was used for statistical analysis. An overall association was observed between FCPD and HLA-DQB1 (P = 0.003), that was largely due to a positive association with HLA-DQB1*0302 and a negative association with HLA-DQB1*0202. Although no association was found between FCPD and TNF-LT microsatellite markers a trend was observed for TNFc (P = 0.037, Pc = 0.15). No association was found between FCPD and INS (P = 0.26). This study confirms an association between FCPD and the MHC using a family-based study design and the stringent ETDT analysis; a novel protective association was found with HLA-DQB1*0202 in Bangladeshi FCPD subjects. The genetic susceptibility to FCPD has features both similar and dissimilar to T1DM.

SPINK1/PSTI mutations are associated with tropical pancreatitis and type II diabetes mellitus in Bangladesh.

BACKGROUND & AIMS: Tropical pancreatitis, including tropical calcific pancreatitis and fibrocalculous pancreatic diabetes, is endemic in parts of Asia and Africa. In a preliminary study, we found serine protease inhibitor, Kazal type 1 (SPINK1) mutations in 6 of 8 patients with fibrocalculous pancreatic diabetes in Bangladesh. A more extensive investigation of patients with pancreatic diseases in Bangladesh, including non-insulin-dependent diabetes mellitus, was undertaken. METHODS: Patients with fibrocalculous pancreatic diabetes (n = 22), tropical calcific pancreatitis (n = 15), and non-insulin-dependent diabetes mellitus (n = 43) and controls (n = 76) from Bangladesh were studied. DNA was extracted, and the SPINK1 gene was sequenced in all patients and 50 controls. Exon 3 was sequenced in an additional 26 controls. RESULTS: SPINK1 N34S mutations appeared in 1 of 76 controls (1.3%), 12 of 22 patients with fibrocalculous pancreatic diabetes (55%; odds ratio, 83; P < 0.00001), 3 of 15 with tropical calcific pancreatitis (20%; odds ratio, 11.2; P = 0.04), and 6 of 43 with non-insulin-dependent diabetes mellitus (14%; odds ratio, 11.9; P = 0.009). P55S was present in 2 of 76 controls (3%) and in 1 of 22 patients with fibrocalculous pancreatic diabetes (5%; P = not significant). A novel Y54H (160T>C) mutation was identified in 1 of 15 tropical calcific pancreatitis patients. CONCLUSIONS: In Bangladesh, the SPINK1 N34S mutation increases the risk of several forms of pancreatic disease, including fibrocalculous pancreatic diabetes, tropical calcific pancreatitis, and non-insulin-dependent diabetes mellitus.

Prevalence of hypertension in Bangladesh: effect of socioeconomic risk factor on difference between rural and urban community.

Several studies reported that migrant Bangladeshis had greater risk for hypertension, diabetes and coronary heart disease compared with the Europeans and other migrant South Asians. So far, there has been no such study among the native population. This paper reports the hypertension prevalence and related risks among native Bangladeshis. A total of 2,361 subjects over 20 years of age were investigated. Overall prevalence rates of systolic and diastolic hypertension in the study population were 14.4 and 9.1 percent respectively. The prevalence of systolic hypertension was significantly higher in rural than in urban participants (P < 0.001). Compared with the poor the rich class had significantly higher prevalence of both systolic (P = 0.002) and diastolic (P = 0.041) hypertension. With increase of age, body mass index (BMI) and blood glucose level were significantly related to hypertension (P < 0.0001); whereas the trend for increasing waist-to-hip ratio (WHR), adjusting for social class, was not significant. Regression analysis showed that age, BMI, rural area and rich class were the strong predictors for hypertension. This study explored that hypertension prevalence in the native Bangladeshis is almost comparable to that of other Asian populations and South Asian migrants.
