An automated telephone intervention improved diet (+3.5 points, p<0.03) and energy expenditure (+80 kcal/day, p<0.03) but did not significantly reduce systolic BP (-2.3 mmHg, p=0.25).

Does an 8-month culturally adapted automated telephone intervention improve diet, physical activity, medication adherence, and blood pressure in urban hypertensive African-American adults?
A culturally adapted automated telephone intervention improved diet quality and physical activity in urban hypertensive African-Americans, though it did not significantly reduce systolic blood pressure.
Effect estimate: Difference: +3.5 points (diet), +80 kcal/day (energy), -2.3 mmHg (SBP)
p-value: p=<0.03 (diet/energy), 0.25 (SBP)
BACKGROUND: Hypertension is more prevalent and clinically severe among African-Americans than whites. Several health behaviors influence blood pressure (BP) control, but effective, accessible, culturally sensitive interventions that target multiple behaviors are lacking. PURPOSE: We evaluated a culturally adapted, automated telephone system to help hypertensive, urban African-American adults improve their adherence to their antihypertensive medication regimen and to evidence-based guidelines for dietary behavior and physical activity. METHODS: We randomized 337 hypertensive primary care patients to an 8-month automated, multi-behavior intervention or to an education-only control. Medication adherence, diet, physical activity, and BP were assessed at baseline and every 4 months for 1 year. Data were analyzed using longitudinal modeling. RESULTS: The intervention was associated with improvements in a measure of overall diet quality (+3.5 points, p < 0.03) and in energy expenditure (+80 kcal/day, p < 0.03). A decrease in systolic BP between groups was not statistically significant (-2.3 mmHg, p = 0.25). CONCLUSIONS: Given their convenience, scalability, and ability to deliver tailored messages, automated telecommunications systems can promote self-management of diet and energy balance in urban African-Americans.
Migneault et al. (Sat,) conducted a rct in Hypertension (n=337). Culturally adapted, automated telephone system vs. Education-only control was evaluated on Medication adherence, diet, physical activity, and blood pressure (Difference: +3.5 points (diet), +80 kcal/day (energy), -2.3 mmHg (SBP), p=<0.03 (diet/energy), 0.25 (SBP)). An automated telephone intervention improved diet (+3.5 points, p<0.03) and energy expenditure (+80 kcal/day, p<0.03) but did not significantly reduce systolic BP (-2.3 mmHg, p=0.25).
