Aim: To assess the prescribing patterns and response to different classes of antihyperglycemic agents in novel clusters of type 2 diabetes (T2D) described in India. Materials and Methods: We attempted to replicate the earlier described clusters of T2D, in 32,867 individuals with new-onset T2D (within 2 years of diagnosis) registered between October 2013 and December 2020 at 15 diabetes clinics located across India, by means of k-means clustering utilizing 6 clinically relevant variables. Individuals who had follow-up glycated hemoglobin (HbA1c) up to 2 years were included for the drug response analysis (n = 13,247). Results: Among the 32,867 participants included in the study, 20,779 (63.2%) were males. The average age at diagnosis was 45 years and mean HbA1c at baseline was 8.9%. The same four clusters described in India earlier were replicated. Forty percent of the study participants belonged to the mild age-related diabetes cluster, followed by insulin-resistant obese diabetes (27%), severe insulin-deficient diabetes (21%), and combined insulin-resistant and insulin-deficient diabetes (12%) clusters. The most frequently used antihyperglycemic agents were sulfonylureas, metformin, and dipeptidyl peptidase-4 inhibitors apart from insulin. While there were significant differences in HbA1c reduction between drugs across clusters, these were largely driven by differences in the baseline (pretreatment) HbA1c. Conclusions: In this new cohort, we were able to reliably replicate the four subtypes of T2D earlier described in Asian Indians. Prescribing patterns show limited usage of newer antihyperglycemic agents across all clusters. Randomized clinical trials are required to establish differential drug responses between clusters.

Background: There exist several barriers to physical activity (PA) among adolescent girls. We therefore developed a culturally acceptable dance/fitness intervention called THANDAV (Taking High-Intensity Interval Training [HIIT] ANd Dance to Adolescents for Victory over noncommunicable diseases [NCDs]). The main aim of this study was to evaluate the THANDAV protocol among Asian Indian girls aged 10 to 17 years. Materials and Methods: THANDAV consisted of a 10-min routine with high- and low-intensity dance steps that was taught to 23 adolescent girls. Heart rate (HR), energy expenditure, body mass index (BMI), and blood pressure (BP) were recorded. Focused group discussions (FGDs) were conducted after the quantitative measurements were completed. Results: The average age of the girls was 13.9 ± 2.1 years, and the mean BMI and BP were 19.8 ± 3.3 kg/m2 and 107/68 (±8/7) mm/Hg, respectively. All participants achieved 80% of their maximum HR during the first dance and managed to sustain this HR throughout the 10-min routine. There was a significant increase in the HR (bpm) [88.7 ± 8.4 to 195.6 ± 11.8, P < 0.001] and VO2 (L/min) [0.025 ± 0.0 to 0.395 ± 0.1, P < 0.001] postintervention. The average energy cost of the activity (metabolic equivalent) was 6.3. The FGDs revealed that THANDAV was a socially acceptable, fun, and energetic form of PA. Conclusions: The THANDAV intervention meets HIIT norms and is a novel culturally appropriate form of PA that is enjoyable, takes little time, and can be done at home. It has the potential to be a sustainable intervention to improve cardiorespiratory fitness and prevent NCDs in Asian Indian adolescent girls. Clinical Trials Registry of India: CTRI/2020/02/023384.

Background: We have recently demonstrated a medium glycemic index for novel high fiber white rice (HFWR) variety compared to regular white rice (RWR). However, substituting HFWR for RWR during the whole day's diet may provide extended benefits. The current study aims to assess the 24 h glycemic responses of a HFWR diet compared to a RWR diet.Methods: Continuous glucose monitoring (CGM) was used to assess the glycemic profile in 18 overweight, non-diabetic Asian Indians aged 25 to 50 in a randomized cross-over design. The volunteers were provided with iso-caloric (≈2100 kcal/day) HFWR or RWR based diets for four continuous days and switched diets after appropriate washout. Fasting blood samples for insulin assessments were collected at baseline and at the end of 4 day feeding. The glucose response in terms of incremental area under the curve (IAUC) was recorded. General linear model was used to assess the adjusted mean change of fasting insulin level of HFWR compared to RWR. Age and sex were adjusted as confounders in the model.Results: The average 24 h glucose response for HFWR was significantly lower (IAUC 66.3 ± 3.1 mg-5 min/dL) than RWR (IAUC 79.8 ± 5.7 mg-5 min/dL). The adjusted mean change in fasting insulin levels from baseline was also lower for HFWR compared to RWR. HFWR elicited a 34% and 30% lower 24 h glycemic and insulin response respectively, compared to RWR.Conclusion: Replacing RWR with HFWR may be a healthier alternative for Asian Indians who are at a higher risk of developing type 2 diabetes.
