Engaging South Asian women with type 2 diabetes in a culturally relevant exercise intervention: a randomized controlled trial.

Background: We examined the efficacy of a culturally relevant exercise program in improving glycated hemoglobin (HbA1c) among South Asian women with type 2 diabetes, compared with usual care. Methods: This was a randomized controlled 8-week pilot study of Bollywood dance among South Asian women with type 2 diabetes. The intervention consisted of 1 h Bollywood dance classes offered twice per week. The primary outcome was change in HbA1c. The effect of attendance on this outcome was also examined. Results: The intervention group demonstrated a decrease in HbA1c from baseline (-0.18% (0.2%); p=0.018) compared with a non-significant increase in the usual care group (+0.03% (0.2%)); p value for difference between groups was 0.032. Participants attending at least 10 of 16 sessions had a statistically significant reduction in weight (-0.69 kg (0.76 kg)) compared with those attending fewer sessions (+0.86 kg (0.71 kg)). Conclusions: These results support culturally relevant dance as a successful exercise intervention to promote HbA1c control, compared with usual care.
