OBJECTIVE
Coronary heart disease has several risk factors that require a multifactorial community intervention approach in prevention efforts. Prevalence of coronary heart disease and its risk factors have been disproportionately high among American Indians. The objective of this study is to evaluate the impact of ambulatory activity levels on the development of coronary heart disease in this population.
METHODS
Using pedometer data and other lifestyle and clinical factors from 2492 participants in the Strong Heart Family Study, we examined the associations of average daily step counts with incident coronary heart disease during an 18 to 20 year follow-up.
RESULTS
After adjusting for potential confounders, participants with daily step counts in the 4th quartile (>7282 steps per day) had significantly lower odds of developing coronary heart disease compared to those in the 1st quartile (<3010 steps per day) (p = 0.035).
CONCLUSIONS
Higher daily step count (over 7282 steps per day) is significantly associated with lower incidence of coronary heart disease among American Indian participants of the Strong Heart Family Study in a 20-year follow-up period.
目的
冠心病有多个危险因素，需要采取多因素社区干预方法来进行预防。冠心病及其危险因素在美洲印第安人中的发病率和流行率一直居高不下。本研究旨在评估活动水平对这一人群冠心病发展的影响。
方法
本研究使用步测计数据和来自 2492 名“强壮心脏家族研究”参与者的其他生活方式和临床因素，在 18 至 20 年的随访期间，考察了平均每日步数与冠心病发病之间的相关性。
结果
在校正了潜在混杂因素后，每日步数处于第 4 四分位（>7282 步/天）的参与者发生冠心病的几率明显低于第 1 四分位（<3010 步/天）（p=0.035）。
结论
在一项 20 年的随访期间，“强壮心脏家族研究”中美洲印第安参与者的每日步数（超过 7282 步/天）较高与冠心病发病率较低显著相关。
