Culturally Adapted Lifestyle Intervention for South Asian Adults With Cardiovascular Risk Factors: The SAHELI Randomized Clinical Trial
Authors' conclusion
In the SAHELI randomized clinical trial, a culturally adapted, group lifestyle intervention was not more effective than written health education materials for CVD risk factor reduction among US South Asian adults, but the intervention was associated with small improvements in self-reported health behaviors.
Study context
- Population
- US South Asian adults aged 18–65 y, overweight or obese, no prior cardiovascular disease (CVD) events, ≥1 additional CVD risk factor (hypertension, dyslipidemia, prediabetes or diabetes); Chicago metropolitan arearandomized
- Participants
- 549 adults
- Comparison
- Culturally adapted group lifestyle intervention vs written health education materials
- Primary endpoint
- Between-group differences in CVD risk factor changes (weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), HbA1c, total cholesterol)
- Follow-up
- Baseline to 12 months
