Military veterans provide a large and diverse population to examine the extent to which compulsory physical activity (PA) in early adulthood is associated with PA later in life.
We assessed self-reported and objectively measured PA and sedentary time in the 900 veterans and 2036 nonveterans with valid data from the 2003-2006 National Health and Nutrition Examination Surveys. Analyses were adjusted for the complex survey design and age, race/ethnicity, education, marital status, and poverty.
Based on self-report, the proportion of veterans and nonveterans meeting PA Guidelines did not differ significantly (51.1% vs. 43.9%, P = .26). However, a greater proportion of veterans reported regular vigorous leisure-time activity (30.4% vs. 19.6%, P = .04) and muscle-strengthening activities (24.4 vs. 16.7, P = .051). Based on objective PA monitoring, activity levels between veterans and nonveterans also did not differ significantly, although mean counts and minutes per day were numerically greater in nonveterans. By self-report (P = .02) and PA monitors (P = .065), estimated sedentary time was greater in veterans than in demographically similar nonveterans.
Veterans were no more likely than nonveterans to meet PA Guidelines, but may have been more likely to perform vigorous activities and conversely, to spend more time in sedentary activities.
军人提供了一个庞大而多样化的人群，可以用来研究年轻时强制性体力活动（PA）与以后生活中体力活动的程度之间的关系。
我们评估了来自 2003-2006 年全国健康与营养调查的 900 名退伍军人和 2036 名非退伍军人的自我报告和客观测量的 PA 和久坐时间数据。分析调整了复杂的调查设计以及年龄、种族/族裔、教育、婚姻状况和贫困因素。
根据自我报告，符合 PA 指南的退伍军人和非退伍军人的比例没有显著差异（51.1%对 43.9%，P =.26）。然而，退伍军人报告有规律的剧烈休闲时间活动的比例更高（30.4%对 19.6%，P =.04）和肌肉强化活动（24.4%对 16.7%，P =.051）。根据客观 PA 监测，退伍军人和非退伍军人之间的活动水平也没有显著差异，尽管非退伍军人的平均计数和每天分钟数在数值上更大。通过自我报告（P =.02）和 PA 监测器（P =.065），退伍军人的估计久坐时间比在人口统计学上相似的非退伍军人更多。
退伍军人与非退伍军人相比，更不可能达到 PA 指南，但他们可能更有可能进行剧烈活动，相反，他们花更多的时间在久坐活动上。
