The Strong Heart Study is a study of cardiovascular disease and its risk factors among American Indian men and women aged 45-74 yr representative of 13 communities from Arizona (AZ), Oklahoma (OK), and North/South Dakota (N/SD). This investigation sought to characterize the amount and type of physical activity and to determine the association between activity and lipids in this population.
Total physical activity (occupational plus leisure) was assessed with a validated questionnaire.
Men and women from OK (21 +/- 19 and 16 +/- 15 h.wk-1; respectively) and N/SD (23 +/- 21 and 17 +/- 17 h.wk-1; respectively) had activity levels that were similar if not lower than the U.S. population with the AZ communities (17 +/- 21 and 10 +/- 14 h.wk-1; respectively) being substantially lower than the other two communities. Total cholesterol (TC), high density lipoprotein cholesterol (HDL-c), and low density lipoprotein cholesterol (LDL-c) levels were lower than the U.S. population.
For most of the population (diabetic men and nondiabetic men and women), activity was significantly associated (P < 0.05) with apolipoprotein (apo) AI after controlling for covariates. With levels of activity as low if not lower than the general U.S. population coupled with high prevalence of obesity and diabetes, efforts to increase physical activity in American Indians are warranted. Hopefully these increases in activity will result in favorable lipid changes as well as decreasing the risk of diabetes which is epidemic in these populations.
“强心研究”是一项针对年龄在45 - 74岁的美国印第安男性和女性的心血管疾病及其危险因素的研究，这些参与者代表了来自亚利桑那州（AZ）、俄克拉何马州（OK）以及北达科他州/南达科他州（N/SD）13个社区的人群。本研究旨在描述该人群体力活动的量和类型，并确定活动与血脂之间的关联。
通过一份经过验证的问卷评估总的体力活动（职业活动加休闲活动）。
来自俄克拉何马州的男性和女性（分别为21±19和16±15小时/周）以及北达科他州/南达科他州的男性和女性（分别为23±21和17±17小时/周）的活动水平即便不比美国人群低也与之相似，而亚利桑那州社区的男性和女性（分别为17±21和10±14小时/周）的活动水平则显著低于其他两个社区。总胆固醇（TC）、高密度脂蛋白胆固醇（HDL - c）和低密度脂蛋白胆固醇（LDL - c）水平低于美国人群。
对于大多数人群（糖尿病男性以及非糖尿病男性和女性），在控制协变量后，活动与载脂蛋白（apo）AI显著相关（P < 0.05）。鉴于该人群的活动水平即便不比美国普通人群低也与之相似，且肥胖和糖尿病患病率较高，因此有必要努力增加美国印第安人的体力活动。希望这些活动量的增加将带来有利的血脂变化，并降低这些人群中流行的糖尿病风险。
