The aim was to objectively monitor steps accrued by a sample of adults with intellectual disabilities and to describe physical activity patterns by monitoring steps taken across weekdays, weekends, and hours of the day using time-stamped technology.
This study used pedometers with time-stamped recording capabilities to measure physical activity behavior of 131 adults with mild to moderate levels of intellectual disabilities living in community-based supported living group settings in Iowa. Participants wore a pedometer for seven consecutive days. All data was collected in 2006 and analyzed in 2007.
The participants accrued 6508+/-3296 steps/day. Controlling for age, participants with mild intellectual disability were more active than participants with moderate intellectual disability (F=7.03, p<.01). A total of 14.1% accumulated 10,000 steps/day. Participants were more active on weekdays than on weekends (Z=-7.36, p<.01), and least active during the evening period compared to the morning and afternoon hours (F(r)=103.3, p<.01).
Physical activity (steps/day) achieved by the majority of this population is insufficient for health benefits, particularly among individuals with moderate intellectual disability. Evenings and weekends are especially inactive time periods.
旨在客观监测一群成年智障人士的步数，并通过使用带时间戳的技术监测工作日、周末及一天中不同时段的步数，来描述其身体活动模式。
本研究使用具备时间戳记录功能的计步器，测量了居住在爱荷华州社区支持性居住集体环境中的131名轻度至中度智障成年人士的身体活动行为。参与者连续七天佩戴计步器。所有数据于2006年收集，并于2007年进行分析。
参与者每天步数为6508±3296步。在控制年龄因素后，轻度智障参与者比中度智障参与者更活跃（F = 7.03，p <.01）。共有14.1%的参与者每天步数累计达10000步。参与者在工作日比周末更活跃（Z = -7.36，p <.01），与上午和下午时段相比，晚上时段最不活跃（F(r)=103.3，p <.01）。
该群体中大多数人的身体活动量（每天步数）对健康益处不足，尤其是中度智障个体。晚上和周末是特别不活跃的时段。
