OBJECTIVE: We sought to study the occurrence of cardiometabolic risk variables, their clustering, and their association with insulin resistance among healthy adolescents in urban south India. RESEARCH DESIGN AND METHODS: School children aged 12-19 years (n = 2,640; 1,323 boys and 1,317 girls) from diverse socioeconomic backgrounds were studied. Demographic, social, and medical details were obtained; anthropometry and blood pressure were measured. Fasting plasma glucose, insulin, and lipid profiles were measured. Clusters of risk variables were identified by factor analysis. Association of insulin resistance (homeostasis model assessment) with individual risk variables and their clusters were assessed. RESULTS: One or more cardiometabolic abnormalities (i.e., low HDL cholesterol, elevated triglycerides, fasting plasma glucose, or blood pressure) was present in 67.7% of children (in 64.8% of normal weight and 85% of overweight children). Insulin resistance was associated with the above abnormalities except HDL cholesterol. It also showed significant positive association with BMI, waist circumference, body fat percentage, and total cholesterol (P < 0.0001). Factor analysis identified three distinct clusters, with minor differences in the sexes: 1) waist circumference and blood pressure; 2) dyslipidemia, waist circumference, and insulin; and 3) waist circumference, glucose, and plasma insulin, with minor differences in the sexes. Insulin was a component of the lipid and glucometabolic cluster. In girls, it was a component of all three clusters. CONCLUSIONS: Cardiometabolic abnormalities are present in nearly 68% of young, healthy, Asian-Indian adolescents and even among those with normal weight. Insulin resistance is associated with individual cardiometabolic factors, and plasma insulin showed association with clustering of some variables.

Cost Effectiveness of the Interventions in the Primary Prevention of Diabetes among Asian Indians: Within trial results of the Indian DiabetesPrevention Programme (IDPP).

Ramachandran A, Snehalatha C, Yamuna A, Mary S, Ping Z.
Objective: In Indian Diabetes Prevention Program (IDPP), a 3 year randomized control trial, life style modification (LSM) and metformin (Met) helped to prevent type 2 diabetes in subjects with impaired glucose tolerance (IGT). The direct medical cost and cost effectiveness of the interventions relative to the control group are reported here. Research design and methods: Relative effectiveness and costs of interventions (LSM, Met and LSM +Met) in IDPP were estimated, from the health care system perspective. Costs of intervention considered were only the direct medical costs. . Direct non medical, indirect and research costs were excluded. Cost effectiveness of interventions were measured as the amount spent on preventing one case of diabetes within the 3year trial period. Results: Direct medical cost to identify one subject with IGT was INR 5,278 ($117). Direct medical costs of interventions over the 3 year trial period were INR 2739 ($61) per subject in the control, INR 10,136 ($225) with LSM, INR 9,881 ($220) with Met and INR 12,144 ($270) with LSM + Met. Number needed to treat to prevent a case of diabetes was 6.4 with LSM, 6.9 with Met and 6.5 with LSM + Met. Cost-effectiveness of preventing one case of diabetes in LSM, Met and LSM + Met were INR 47,341 ($1052), INR 49,280 ($1095), and INR 61,133 ($1359), respectively. Conclusion: Both LSM and Met were cost-effective interventions for preventing diabetes among high risk individuals in India; perhaps in other developing countries as well. The long-term cost-effectiveness of the interventions needs to be assessed.

OBJECTIVE: This study aimed to assess the direct cost incurred by diabetic subjects who were in different income groups in urban and rural India, as well as to examine the changing trends of costs in the urban setting from 1998 to 2005. RESEARCH DESIGN AND METHODS: A total of 556 diabetic subjects from various urban and rural regions of seven Indian states were enrolled. A brief uniform coded questionnaire (24 items) on direct cost was used. RESULTS: Annual family income was higher in urban subjects (rupees [Rs] 100,000 or $2,273) than in the rural subjects (Rs 36,000 or $818) (P < 0.001). Total median expenditure on health care was Rs 10,000 ($227) in urban and Rs 6,260 ($142) in rural (P < 0.001) subjects. Treatment costs increased with duration of diabetes, presence of complications, hospitalization, surgery, insulin therapy, and urban setting. Lower-income groups spent a higher proportion of their income on diabetes care (urban poor 34% and rural poor 27%). After accounting for inflation, a secular increase of 113% was observed in the total expenses between 1998 and 2005 in the urban population. The highest increase in percentage of household income devoted to diabetes care was in the lowest economic group (34% of income in 1998 vs. 24.5% in 2005) (P < 0.01). There was a significant improvement in urban subjects in medical reimbursement from 2% (1998) to 21.3% (2005). CONCLUSIONS: Urban and rural diabetic subjects spend a large percentage of income on diabetes management. The economic burden on urban families in developing countries is rising, and the total direct cost has doubled from 1998 to 2005.

OBJECTIVE: The study was done to find out the levels of awareness on diabetes in urban adult Indian population and to identify factors that influenced the awareness, including presence of diabetes. RESEARCH DESIGN AND METHODS: In population aged >/=20 years (n=3681, M=1769, F=1912), details regarding awareness about diabetes in relation with physical activity, healthy and unhealthy diet, causes, symptoms, prevention, complications and measures to improve health were collected using a questionnaire. A high total score indicated good knowledge. Influence of age, gender, educational status, occupation and presence of diabetic history was analysed. RESULTS: Fifty percent of subjects scored less than15. Maximum scored was 51/65. The median total score was 16. Total score was significantly lower in women than in men (15.0 versus17.0, p<0.0001). Educational status was low in women. Higher education (16.0 versus12.0, p<0.0001) and professional or executive jobs (17.0 versus 15.0, p<0.0001) were significantly associated with better awareness. Age had no influence. Knowledge regarding causes of diabetes, its prevention and the methods to improve health was significantly low among the general population. Diabetic subjects had better knowledge about symptoms of diabetes and the preventive aspects. CONCLUSIONS: The low median score indicated that the awareness was generally poor. The score was low especially in women and subjects with low education. The study highlights the urgent need for strategies to spread awareness about diabetes in the general population. Diabetic subjects also required better education on many aspects.

On going studies
Indian Diabetes Prevention Programme II
A role of glitazones, in the prevention of diabetes has been shown in the Troglitazone in Prevention of Diabetes (TRIPOD) study involving 235 Hispanic women with previous gestational diabetes.  The subjects who remained free of diabetes during the drug treatment had stable glucose concentrations and stable b cell function over a period of 4.5 years.  A role for pioglitazone in prevention of diabetes has been shown in a Chinese study.   There are no studies from India showing beneficial effect of pioglitazone in prevention of diabetes.  Efficiency of metformin as a preventive agent was shown in the Indian population with IGT in the Indian Diabetes Prevention Programme (IDPP-1).  In this study another insulin sensitizer namely pioglitazone is being tested for its usefulness as a drug for prevention of diabetes.
Aim of the study :

    • To find out whether pioglitazone is more effective than the standard care with life style modification in preventing conversion of IGT to diabetes.
    • To assess the effect of the drug on anthropometry and biochemical parameters including b cell function and insulin resistance.   

407 IGT subjects selected from the population were randomized.  The study is now in the 3rd year of follow up. The outcome will be analysed when the international advisory committee decides to terminate the study after preliminary evaluation of the results.

Inter action of genetic and lifestyle factors on the incidence of type 2 diabetes.

Principal Contractor for India: Prof A. Ramachandran

The Integrated project InterAct is an Europeon Commission funded, large scale collaboration between nine European countries and India.

Aims:

  • To discover how genetic and lifestyle behavioural factors, particularly diet and physical activity, interact in their influence on the risk of developing type 2 diabetes.
  • To investigate how these discoveries may help to prevent the development of diabetes.

There are four research lines and contribution from our center will be to the fourth aim of the project:
  
To construct a consortium of life style intervention diabetes prevention  trials in order to study the association of the genetic variation with differential response to the life style intervention and to consider the implications of these findings for preventive action.

(For this, blood samples collected in the IDPP trial will be utilized)
