Objective: To compare physical activity (PA) patterns in pregnant woman with and without gestational diabetes (GDM) and to assess the effects of an exercise intervention on change in PA patterns, blood glucose levels and pregnancy outcomes in GDM women.Methods: For the first objective, PA patterns were studied in 795 pregnant women with and without GDM. For the second objective, the Women in India with Gestational Diabetes Strategy-Model of Care (WINGS-MOC) intervention were evaluated in 151 women out of 189 with GDM. PA was assessed using a validated questionnaire and a pedometer. Changes in PA patterns, glycemic parameters and neonatal outcomes were evaluated.Results: Overall, only 10% of pregnant women performed recommended levels of PA. Women with GDM were significantly more sedentary compared to those without GDM (86.2 vs. 61.2%, p<0.001). After the MOC was implemented in women with GDM, there was a significant improvement in PA and a decrease in sedentary behaviour amongst women (before MOC, moderate activity: 15.2%, sedentary: 84.8% vs. after MOC-moderate: 26.5%, sedentary: 73.5%; p<0.001), and an increase in their daily step count from 2206/day to 2476/day (p<0.001). Fasting 1 and 2-h postprandial glucose values significantly decreased (p<0.001 for all). Sedentary behaviour was associated with a fourfold higher risk (p=0.02), and recreational walking with 70% decreased risk, of adverse neonatal outcomes (p=0.04) after adjusting for potential confounders.Conclusions: PA levels are inadequate amongst this group of pregnant women studied i.e. those with and without GDM. However, a low-cost, culturally appropriate MOC can bring about significant improvements in PA in women with GDM. These changes are associated with improved glycemic control and reduction in adverse neonatal outcomes. [ABSTRACT FROM AUTHOR]

Aims This paper attempts to describe the patterns of exercise and the perceived benefits and barriers to exercise in an urban south Indian population. Methods Study participants were recruited from the baseline survey of the D-CLIP (Diabetes Community Lifestyle Improvement Program). Frequency, duration, type and location of exercise were assessed using a questionnaire, while a Likert type scale was used to assess perceived benefits of and barriers to exercise. Quality of life was measured using the EQ-5D. Results Out of 1281 participants (63.7% males), 24.1% reported doing ≥150 min of exercise/week (“exercisers”) compared to 75.9% “non-exercisers”. Exercisers were significantly older (47 vs. 43 years), better educated (68.8% vs. 60%), had a higher monthly income (41% vs. 29.2%), consumed more fruits (38.2% vs. 25.6%) and vegetables (84.1% vs. 77.7%) and had better perceived state of health (81.1% vs. 76.8%), compared to non-exercisers. Exercisers had significantly lower HOMA-IR, higher Matsuda index and lower prevalence of low HDL cholesterol compared to non-exercisers. However, there were no significant differences in cardio-metabolic risk factors like diabetes, hypertension and obesity between the two groups. Walking was the most common type of exercise. Both exercisers and non-exercisers perceived the benefits of exercising, but barriers weighed more heavily on exercise behaviour. Conclusions Urgent steps are needed to improve overall exercise levels in India by addressing barriers and improving the quality of exercise performed so as to enhance overall metabolic health.
