背景资料：一个有限的身体的证据，主要是基于自我报告，是关于身体活动水平之间的American-Indian adults.Purpose：本研究旨在检查身体活动水平客观使用计步器之间的一个大队列的American-Indian成人参与者的强心家庭研究（SIFS）。在2001年至2003年期间，使用Accusplit AE 120计步器对来自13个美国印第安社区的2604名年龄在18-91岁之间的美国印第安成年人的身体活动水平进行了为期7天的评估。人体测量也进行了评估。所有数据分析均在2008年进行。经t检验的Pearson相关系数被用来检验每天平均步数与年龄和人体测量变量之间的关系。受试者被放置在年龄和BMI类别（根据国家心脏，肺和血液研究所的临界点），以检查随着年龄和BMI的增加体力活动的趋势。按年龄组划分的男性平均步数为5384步（18-29岁）; 5120（30-39岁）; 50 40（40-49岁）; 4561（50-59岁）; 4321（60-69岁）;和3768人（年龄≥ 70岁）和妇女，5112人（30-39岁）; 5054人（40-49岁）; 4582人（50-59岁）; 3653人（60-69岁）; 3770人（年龄≥ 70岁）。随着年龄的增长，体力活动呈显著的线性趋势（男性p=0.002，p
Background: A limited body of evidence, mostly based on self-report, is available regarding physical activity levels among American-Indian adults.Purpose: This study aims to examine physical activity levels objectively using pedometers among a large cohort of American-Indian adult participants in the Strong Heart Family Study (SHFS).Methods: Physical activity levels in 2604 American-Indian adults, aged 18-91 years, from 13 American-Indian communities were assessed using Accusplit AE120 pedometers over a period of 7 days during 2001-2003. Anthropometric measurements were also assessed. All data analyses were conducted in 2008. Age-adjusted Pearson correlations were used to examine the relationship between average steps per day and age and anthropometric variables. Subjects were placed in age and BMI categories (according to National Heart, Lung, and Blood Institute cut points) to examine trends in physical activity with increasing age and BMI.Results: Daily pedometer steps ranged from 1001 to 38,755. Mean step counts by age group for men were 5384 (aged 18-29 years); 5120 (aged 30-39 years); 5040 (aged 40-49 years); 4561 (aged 50-59 years); 4321 (aged 60-69 years); and 3768 (aged >= 70 years) and for women, 5038 (aged 18-29 years); 5112 (aged 30-39 years); 5054 (aged 40-49 years); 4582 (aged 50-59 years); 3653 (aged 60-69 years); and 3770 (aged >= 70 years). A significant linear trend in physical activity was noted with increasing age (p=0.002 for men, p
