Article from the Journal of the American Medical Association

JAMA Results Reported: "At 6 months, levels of LDL-C were significantly lower in intervention participants (mean difference, −5 mg/dL [95% CI, −9 to 0]; P = .04). There were concurrent reductions in systolic blood pressure (−7.6 mm Hg [95% CI, −9.8 to −5.4]; P < .001) and BMI (−1.3 [95% CI, −1.6 to −0.9]; P < .001), significant increases in physical activity (+293 metabolic equivalent task min/wk [95% CI, 102 to 485]; P = .003), and a significant reduction in smoking (26% vs 44%; relative risk, 0.61 [95% CI, 0.48 to 0.76]; P < .001). The majority reported the text-message program to be useful (91%), easy to understand (97%), and appropriate in frequency (86%)."
