Moderate-to-vigorous physical activity changes in a diabetes prevention intervention randomized trial among South Asians with prediabetes – The D-CLIP trial

•The impact of the diabetes prevention intervention on MVPA in South Asians is examined.•D-CLIP wasa a six-month, culturally-tailored translational study of the Diabetes Prevention Program carried out in South Asians.•The D-CLIP intervention increased MVPA by nearly an hour.•The intervention increased the proportion of respondents who reported ≥150 minutes of weekly MVPA.•Effects of the intervention were strongest at six months of follow-up. The Diabetes Community Lifestyle Improvement Program (D-CLIP) was a lifestyle education program to prevent diabetes in South Asians with prediabetes. This paper examines the impact of the D-CLIP intervention on moderate-to-vigorous intensity physical activity (MVPA). This randomized controlled trial to prevent diabetes included 573 individuals with prediabetes from Chennai, India. The intervention was designed to increase MVPA to ≥150 minutes per week. MVPA was measured by questionnaire at baseline, six, 12, 18, 24, 30 and 36 months of follow-up. Random effects models were used to examine the relationship between treatment group and odds of reporting ≥150 weekly minutes of MVPA and to examine the impact of the intervention on weekly MVPA. With the exception of the proportion of respondents at baseline with a high waist circumference, selected sample characteristics did not differ at baseline between the intervention and control groups. The intervention significantly (p
