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
Intervention vs Control
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
