We studied whether cardiovascular health promotion mHealth intervention was effective in a sample of adults entering college. 301 Freshmen at a Northwestern University were cluster randomized by residence hall. We compared 2 conditions delivered custom smartphone apps: (1) Cardiovascular Health, an intervention addressing behaviors related to cardiovascular disease risk; or (2) Whole Health, an active control addressing behaviors unrelated to cardiovascular disease. The primary outcome was the AHA's Life's Simple Seven (LSS) composite score. Outcomes were assessed in-person at baseline, 1 and 2 years. Linear mixed models were used to compare the groups on the composite score. We found no significant group, time, or group by time differences in LSS. Participants were relatively healthy at baseline and stable over time. Cholesterol increased by 5.24 mg/dL from Baseline to Year 1 and by 7.39 mg/dL from Baseline to Year 2 in both groups. mHealth interventions focused on cardiovascular health did not show appreciable difference from those addressing more general health behaviors. Low engagement in the intervention could have contributed to the null findings and future research is needed to determine if mHealth strategies could be improved as an intervening modality.
我们研究了心血管健康促进移动健康干预措施对刚进入大学的成年人样本是否有效。西北大学的301名新生按宿舍楼进行整群随机分组。我们比较了通过定制智能手机应用程序提供的两种情况：（1）心血管健康，一种针对与心血管疾病风险相关行为的干预措施；（2）全面健康，一种针对与心血管疾病无关行为的积极对照措施。主要结局是美国心脏协会的“生命简单七要素”（LSS）综合评分。在基线、1年和2年时进行了面对面的结局评估。使用线性混合模型比较两组在综合评分上的差异。我们发现LSS在组间、时间或组间与时间交互作用方面均无显著差异。参与者在基线时相对健康，且随时间保持稳定。两组的胆固醇水平从基线到第1年增加了5.24mg/dL，从基线到第2年增加了7.39mg/dL。专注于心血管健康的移动健康干预措施与针对更一般健康行为的干预措施相比没有显著差异。干预措施参与度低可能导致了无显著结果，未来需要开展研究以确定移动健康策略作为一种干预方式是否可以得到改进。
