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.

Urinary iodine status and thyroid dysfunction: a Bangladesh perspective.

Iodine deficiency is endemic in Bangladesh. Compulsory iodization of table salt was introduced since 1993 to prevent and improve thyroid disorders in the country. Urinary iodine status, thyroid function and antithyroid antibodies were studied in 397 newly diagnosed thyroid patients and 94 age-sex matched controls. Among thyroid patients, 96 were hyperthyroid, 185 euthyroid and 116 hypothyroid. Mean and median urinary iodine were higher (p=0.075) in thyroid patients (26.13+/-0.91 and 23.03) than controls (22.65+/-1.47 and 18.59); in hyperthyroid and euthyroid than hypothyroid (p=0.020); in multinodular (28.08+/-2.80 and 26.94) and diffuse (27.35+/-1.19 and 26.71) goitre than uninodular (23.91+/-2.37 and 19.14) and nongoitrous (NG, 21.5+/-2.05 and 18.27) (p=0.098) patients but no sex difference (p=0.466). Antimicrosomal (26.7%) and antithyroglobulin (34%) antibodies were more frequently positive among thyroid patients than controls (6.4% and 12.8% respectively) (p=0.00002 and p=0.00005 respectively). Antibody positivity was higher in diffuse (82/228) and multinodular (20/47) goitre than nongoitrous (20/56) and uninodular (13/66) goitre (p=0.046) as well as in hypothyroid (55.2%) and hyperthyroid (36.5%) than euthyroid (19.5%) patients (P<0.001). Urinary iodine correlated neither with antimicrosomal (thyroid patients: p=0.597 and control: p=0.112) nor with antithyroglobulin (thyroid patients: p=0.388 and control: p=0.195) antibody. Thyroid autoimmunity and dysfunction seems common; and interaction of salt iodization with iodine status and thyroid disorders may be important in Bangladesh.

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.

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.

The Diabcare-Asia 1998 study--outcomes on control and complications in type 1 and type 2 diabetic patients.

UNLABELLED: The aim of this study was to describe the glycaemic and metabolic control and diabetes-related complications in type 1 and type 2 Asian patients. METHODS: Data of diabetes patients from 230 diabetes centres in 12 Asian regions were collected on a retrospective-prospective basis through review of medical records, interview and laboratory assessments. Analysis of glycated haemoglobin (HbA1c) was carried out in central laboratories appointed by Bio-Rad. The data collection case record forms were scanned electronically. RESULTS: 22177 patients with valid data made up the analysis population. Among patents with type 1 and type 2 diabetes, there was a higher proportion of women than men (53% vs. 47% for type 1 patients and 56% vs. 44% for type 2 diabetes). Hypertension (61%) and overweight (40% with BMI > or = 25 kg/m2 were common in type 2 patients. Dyslipidaemia was also present in at least half of both types of patients. Control of glycaemia (mean HbA,1c and fasting blood glucose [FBG]) was poor in type 1 (9.9 +/- 2.5%; 10.2 +/- 5.2 mmol/l) and type 2 patients (8.5 +/- 2.0%; 8.9 +/- 3.4 mmol/l). Glycaemia in the majority of both types of patients fell short of those stipulated by various guidelines. In type 2 patients, glycaemia deteriorated (HbA1c > 7.5%, FBG > or = 7.0 mmol/l) with duration of diabetes > 7 years. Both types of diabetes appear to share a similar high prevalence of complications of cataract, retinopathy and neuropathy, although the prevalence of cataract (27%) and neuropathy (35%) was higher in type 2 diabetes. Screening for microalbuminuria was not common. CONCLUSIONS: The Inadequate metabolic and hypertension control, especially in type 2 patients, needs to be addressed.

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.

Cardiovascular risk factors: distribution and prevalence in a rural population of Bangladesh.

BACKGROUND: Little is known about the cardiovascular risk factors in the Bangladeshi population. We examined 'classic' risk factors, including central obesity, in a rural population. METHODS: Non-biochemical variables were examined in 238 men and 272 women aged 18 years or more (mean +/- standard deviation 38.1 +/- 10.7 years in men and 36.0 +/- 9.8 in women). Fasting blood glucose and total cholesterol concentrations were determined in a sub-sample of 106 men and 135 women. RESULTS: Men and women had a similar body mass index (20.4 +/- 3.1 vs 20.8 +/- 3.4 kg/m2), waist circumference (72.8 +/- 7.6 vs 71.4 +/- 8.7 cm), systolic blood pressure (118.4 +/- 13.7 vs 119.5 +/- 17.7 mmHg), diastolic blood pressure (75.9 +/- 9.9 vs 74.6 +/- 11.5 mmHg), total cholesterol (155.7 +/- 36.0 vs 162.0 +/- 35.2 mg/dl) and blood glucose level (89.0 +/- 14.9 vs 86.2 +/- 9.6 mg/dl. After categorization of these variables, the prevalence of thinness (body mass index < 18.5; 30.0 vs 30.3%), obesity (body mass index > or = 30; 0.8 vs 1.1%), hypertension (systolic blood pressure > or = 140 and/or diastolic blood pressure > or = 90 or medication; 9.8 vs 15.6%), hypercholesterolemia (total cholesterol > or = 240; 2.8 vs 3.0%) and diabetes mellitus (blood glucose > or = 126; 2.9 vs 0.7%) remained similar between the sexes. However, central obesity (waist circumference > or = 94 cm in men and > or = 80 cm in women) was less frequent (2.9 vs 16.8%; P = 0.001) in men. Overall, tobacco consumption (57.1 vs 23.2%; P = 0.001) and smoking (50.3% vs 2.9%; P = 0.001) were more frequent in men, but chewing tobacco consumption was similar (16.3 vs 21.4%; P = 0.095). CONCLUSIONS: Our sample size is small, and larger studies are necessary for a more accurate description of the risk factors.

Status of antithyroid antibodies in Bangladesh.

To study autoimmunity among thyroid diseases, 397 thyroid patients (age 30 (13) years; M/F 75/322) from two referral centres in Bangladesh and 94 healthy controls (age 30 (13) years; M/F 24/70) were studied for antimicrosomal and antithyroglobulin antibodies. Thyroid patients were clinically grouped as suspected autoimmune thyroid disease (AITD), non-autoimmune, or indeterminate groups (where no decision could be reached). Antimicrosomal antibody was strongly positive in 19.4% and weakly positive in 7.3% of patients but only 4.3% and 2.1% respectively in the controls (chi(2) = 17.852; p = 0.000) whereas strong and weak positivity were 27.2% and 6. 8% in patients compared with 8.5% and 4.3% respectively in the controls (chi(2) = 16.916; p = 0.000) for antithyroglobulin antibody. Antibodies were positive in 63.0% with Hashimoto's thyroiditis, 36.4% with Graves' disease, and 44.7% with atrophic thyroiditis among the autoimmune group. In the non-autoimmune group antibodies were positive in 100% with multinodular hypothyroidism, 46.7% with subacute thyroiditis, 40.0% with suspected iodine deficiency goitre, 31.3% with toxic multinodular goitre, 30.8% with non-toxic solitary nodules, and 19.4% with simple diffuse goitre. None was positive for antimicrosomal antibody without being positive for antithyroglobulin antibody. The two antibodies strongly correlated in both patients (r = 0.977, p = 0.000) and controls (r = 0.986, p = 0.000). About 9% (36/397) of patients were mismatched with the final diagnosis on antibody measurement; most of them had Hashimoto's thyroiditis (33/36). Prevalence of AITD among thyroid patients was 48.36%. Specificity of antimicrosomal and antithyroglobulin antibodies were 93% and 87%. It was concluded that AITD is not uncommon in Bangladesh; antimicrosomal antibody is a useful marker for AITD and unless antibodies are checked, an appreciable number of patients with AITDs will remain undetected.

Genetic background of diabetic and nondiabetic sibs in young Bangladeshis.

The prevalence of diabetes mellitus in the young is higher in Bangladesh like other Asian developing nations. Albeit, undernutrition has been shown to be associated with diabetes in the young, not all such individuals are diabetic. Diabetes Mellitus is a multigenic disease. In IDDM, DR3/4 heterozygotes were shown to have a greatly increased risk of developing the disease, suggesting the concept of genetic factor(s) being involved in the development of diabetes. Therefore, this study was undertaken to determine the distribution of HLA class II alleles (DRB) and to identify the HLA associated risk for developing diabetes mellitus in the young Bangladeshis. A total of fifty individuals were investigated. Half of them (n=25) were diabetic patients, registered in BIRDEM and half the participants were their non-diabetic sibs. A genomic DNA PCR and Enzyme Linked Probe Hybridization Assay (ELPHA, Bio-test, Germany) was used to determine HLA class II alleles (DRB1, DRB 3, 4, 5) by in vitro amplification of DRB gene. Among all the sero-equivalent antigens found in the study subjects, the prevalence of DR15 (DR2) was overrepresented, both in the diabetic subjects and in their non-diabetic sibs. Moreover, compared with the non-diabetic group the diabetic patients showed higher frequency of DR15 alleles (39 and 25%) though the difference was not significant (chisq. 1.7, p>0.05). Next to DR15, DR4 was the most prevalent HLA-DRB gene found in the study population. Interestingly, the frequency of DR4 was higher in the diabetic than in the non-diabetic group (20 vs. 14%). The study showed that the DR15 and DR4 were the most prevalent in the study population. Moreover, DR7 though not very significant, was higher in non-diabetic compared to their diabetic sibs. Comparison between the diabetic and non-diabetic sibs could have been interesting and significant but we could not confirm our findings, possibly, due to small sample size. A study in a larger paired sample of unrelated population is also needed to substantiate our findings, and also to prove the susceptibility or resistant haplotype in the young diabetic subjects.

High prevalence of diabetes mellitus and impaired glucose tolerance in the Sultanate of Oman: results of the 1991 national survey.

A national survey of glucose intolerance and cardiovascular disease risk factors in Oman has demonstrated a high prevalence of diabetes (10%) and impaired glucose tolerance (IGT, 13% in females and 8% in males). Prevalence of diabetes rose with age to a maximum of over 30% in both sexes. Prevalence of total glucose intolerance (diabetes and IGT combined) exceeded 50% in the seventh (females) and eighth (males) decade of life.

Metabolic and hormonal profile of the offsprings of conjugal diabetics.

Oral glucose tolerance response to blood glucose, serum immunoreactive insulin (IRI) and plasma free fatty acid (FFA) levels were studied on 159 offsprings of both parent diabetics (connubials). Fasting serum cholesterol, triglyceride, phospholipid and total lipids were also measured in these subjects. We detected 6 diabetics out of 159 connubials at the time of our study. FFA level in 6 diabetic connubials were higher all time intervals than 153 non-diabetics connubials. Fasting and one hour post glucose response were less in 6 diabetic connubial but two hours post glucose IRI response to both 6 diabetic connubials and 153 non-diabetic connubials were same indicating a delayed insulin secretion in response to oral glucose level in 6 diabetic connubials.

Coccinia indica in the treatment of patients with diabetes mellitus.

Coccinia indica is a creeper which grows wildly in Bangladesh and in many parts of the Indian sub-continent. The plant has been used since ancient times as an antidiabetic drug by physicians who practice the Indian system of medicine known as Ayurvedha. We have conducted a double blind control trial with preparation from the leaves of the plant on uncontrolled, maturity onset diabetics. The trial lasted for six weeks for an individual patient. Out of the 16 patients who received the experimental preparations 10 showed marked improvement in their glucose tolerance while none out of the 16 patients in the dummy group showed such a marked improvement. This difference is highly significant (kappa 2 with Yates' correction = 11.7, P < 0.001).
