Metabolic syndrome of prediabetic and diabetic subjects in a Bangladeshi population

Prevalence of type 2 diabetes and impaired glucose regulation with associated cardiometabolic risk factors and depression in an urbanizing rural community in bangladesh: a population-based cross-sectional study

BACKGROUND

To determine the prevalence of type 2 diabetes (T2DM) and impaired glucose regulation (impaired fasting glucose [IFG] and impaired glucose tolerance [IGT]) in an urbanizing rural population of Bangladesh and associated cardiometabolic risk indicators and depression.

METHODS

A total of 2,293 subjects aged ≥20 years in an urbanizing rural Bangladeshi community were investigated. Socio-demographic and anthropometric details, blood pressure, fasting plasma glucose (FPG), 2 hours after 75 g plasma glucose (2hPG), glycosylated hemoglobin, fasting serum insulin and lipid profiles were studied. Presence of depressive symptoms using Montogomery-Asberg Depression Rating Scale was also assessed.

RESULTS

The prevalence of IFG, IGT, IFG+IGT, and T2DM were 3.4%, 4.0%, 1.2%, and 7.9%, respectively. The prevalence of T2DM and impaired glucose regulation differed between males and females, but, both increased with age in both sexes. FPG and 2hPG had positive correlation. Employing logistic regression, it was found that increased age, waist to hip ratio, systolic blood pressure, total cholesterol, triglycerides, and depression were independent risk indicators for diabetes. Both insulin resistance and β-cell deficiency were significantly related for causation of diabetes. Among the study population, 26.2% had general obesity, 39.8% central obesity, 15.5% hypertension, 28.7% dyslipidemia, 17.6% family history of diabetes, and 15.3% had depression. Physical inactivity and smoking habits were significantly higher in male.

CONCLUSION

Rising prevalence of diabetes and impaired glucose regulation in this urbanizing rural population exist as a significant but hidden public health problem. Depression and other cardiometabolic risk indicators including obesity, hypertension, and dyslipdemia were also prevalent in this population.

Visceral Adiposity Index and pattern of dyslipidaemia at different stages of glucose intolerance-A study from India

AIM

To see the pattern of dyslipidaemia and Visceral Adiposity Index (VAI) at different stages of glucose intolerance in Indian population.

METHODS

Data of 600 subjects were considered for this analysis. Waist circumference and BMI were recorded. OGTT and lipid profile were done. Subjects were divided into three groups; Group 1 (Normoglycaemic), Group 2 (Prediabetes) and Group 3 (new DM). Subjects having one or more lipid parameters outside the targets recommended by ADA were considered to have dyslipidaemia. VAI, a sex-specific index, was calculated.

RESULTS

LDL-C was the most common isolated single abnormality (84.5%), followed by HDL-C (58.7%) and triglycerides (49.7%) among the total subjects. 73% had high LDL-C and 56% had low HDL-C even in normoglycaemic subjects. LDL-C abnormality was similar in prediabetes and diabetes. Commonest combination of two abnormalities was seen mainly with LDL-C and HDL-C. Mean VAI increased at different stages of glucose intolerance and VAI≥2.3 gave sensitivity of 61.2% and specificity of 59.7% to detect glucose intolerance.

CONCLUSIONS

The most common single lipid abnormality was high LDL-C. Combination of two abnormalities was seen with LDL-C and HDL-C. VAI increased at different stages of glucose intolerance. These findings may be useful for targeting high-risk population.
