Aims: The aims were to assess effect of a short training programme on non-communicable diseases (NCDs), particularly diabetes on school teachers and also on students who were in turn educated by them. Lifestyle changes made by both groups were assessed 6months later.Methods: Graduate teachers (n=1017) from 2 districts in Tamilnadu, India were trained using audio visual aids in batches of 100, on healthy lifestyle practices, prevention and management of diabetes. Pre and post training knowledge scores were assessed using questionnaires. Each teacher was requested to impart similar education to 100 high school students within 3months. Impact of the training on teachers and students was assessed using questionnaires 6months later. Feedback from the students' parents was also collected.Results: A total of 1017 teachers (men: 33.8%, women: 66.2%, urban: 68.8%, rural: 31.1%) were trained. Among them, 651 (men: 31.3%, women: 68.7%) responded for impact evaluation. Changes in knowledge and attitude were reported by 93.7% of teachers. Improvement in lifestyle of the students was assessed by 587 teachers, 60.4% of the students avoided junk foods, 57.5% advised their family members on diabetes. Outdoor games were played by 50.8% of the students. Improvement in knowledge, changes in lifestyle and a positive attitude towards health care delivery were achieved among teachers and students through this training programme.Conclusions: Significant improvement in health perception among the teachers and students occurred even with a short training. It has demonstrated that non-medical personnel like teachers are efficient in disseminating health information on lifestyle diseases especially diabetes. [ABSTRACT FROM AUTHOR]

Aims To assess the beneficial effects of the components of lifestyle intervention in reducing incidence of diabetes in Asian Indian men with impaired glucose tolerance (IGT) in India. Methods This analysis was based on a 2 year prospective, randomized controlled primary prevention trial in a cohort of Asian Indian men with IGT ( n = 537) (Clinical Trial No: NCT00819455 ). Intervention and control groups were given standard care advice at baseline. Additionally, the intervention group received frequent, mobile phone based text message reminders on healthy lifestyle principles. Dietary intake and physical activity habits were recorded by validated questionnaires. The lifestyle goals were: reductions in consumption of carbohydrates, oil, portion size and body mass index of at least 1 unit (1 kg/m 2 ) from baseline and maintenance of good physical activity. The association between diabetes and lifestyle goals achieved was assessed using multiple logistic regression analyses. Changes in insulin sensitivity (Matsuda's insulin sensitivity index) and oral disposition index during the follow-up were assessed. Results At the end of the study, 123 (23.8%) participants developed diabetes. The mean lifestyle score was higher in the intervention group compared with control (2.59 ± 1.13 vs. 2.28 ± 1.17; P = 0.002). Among the 5 lifestyle variables, significant improvements in the 3 dietary goal were seen with intervention. Concomitant improvement in insulin sensitivity and oral disposition index was noted. Higher lifestyle score was associated with lower risk of developing diabetes (odds ratio: 0.54 [95% CI: 0.44–0.70]; P < 0.0001). Conclusions Beneficial effects of intervention were associated with increased compliance to lifestyle goals. The plausible mechanism is through improvement in insulin sensitivity and beta cell preservation. [ABSTRACT FROM AUTHOR]

Objective: This was a 5 year comparative analysis of the incidence of type 2 diabetes in men who had persistent impaired glucose tolerance (P-IGT) versus transient impaired glucose tolerance (T-IGT). P-IGT (positive IGT on two oral glucose tolerance tests (OGTT), T-IGT (IGT in first OGTT and normal glucose tolerance (NGT) in the 2nd OGTT)., Methods: The samples were collected from a randomized controlled diabetes prevention study. The prevention study was done using lifestyle modification (LSM) promoted by use of mobile short message services (SMS) for 2 years. The control group of the randomized study who received advice on LSM at only the baseline formed the P-IGT group for the 3 years follow up study (n=236). T-IGT (n=569) were available from those who had NGT on the 2nd OGTT while screening for the prevention study. The total diabetes incidence at 5 years in the study groups were compared using standard OGTT (WHO criteria)., Results: The conversion rate to diabetes in 5 years was significantly lower among T-IGT than among P-IGT, OR=0.202 (95% CI, 0.145-0.296,p< 0.0001). P-IGT had higher rate of risk factors for diabetes than T-IGT., Conclusion: The risk of conversion to diabetes was 80 percent lower in T-IGT than in P-IGT. Identification of P-IGT will help in selecting persons who require early intervention for diabetes., (© Journal of the Association of Physicians of India 2011.)
