目的：本研究的目的是描述40，261名加利福尼亚本地人自我报告的中度和剧烈体力活动（PA）的患病率，这些活动与年龄，性别，教育，种族/民族和自我报告的疾病风险因素有关。研究方法：受试者，从加州双胞胎计划，完成了一份问卷，其中包括三个PA的问题，并根据他们的PA水平进行分类：中度和强烈的PA足以满足CDC和ACSM指南。人口统计学变量之间的关系，慢性病的危险因素，并满足PA指南的报告。结果：对于中度和重度PA，分别有22.3%和37.4%的总组报告符合指南。大约一半的受试者符合中度和剧烈PA的持续时间或频率标准，但不是两者都符合。分别只有11.2%和27.4%的患者报告没有中度或重度PA。中度和重度PA均存在显著的年龄和教育梯度。中度和重度PA指南与慢性病危险因素的患病率呈负相关。PA的频率和持续时间都需要充分表征PA和健康结果之间的关联。结论：这些数据表明：1）与全国范围内的成年人相比，该样本中足够的中度和剧烈PA的患病率较高，久坐行为的患病率较低，2）与中度PA相比，剧烈PA与改善的健康结果之间的关联更大，3）PA指南必须关注活动的频率和持续时间，以及4）中度和重度PA的年龄和教育梯度可能对更有效地针对指南以改善美国成年人的PA患病率具有影响。
Purpose: The purpose of this study was to describe the prevalence of self-reported moderate and vigorous physical activity (PA) among 40,261 native Californians in relation to age, gender, education, race/ethnicity, and self-reported disease risk factors. Methods: Subjects, from the California Twin Program, completed a questionnaire that included three PA questions and were categorized by their level of PA: moderate and vigorous PA sufficient to meet CDC and ACSM guidelines. The relationship between demographic variables, chronic disease risk factors, and meeting the PA guidelines are reported. Results: For moderate and vigorous PA, 22.3% and 37.4% of the total group reported meeting the guidelines respectively. Approximately one-half of all subjects met either duration or frequency criteria, but not both, for moderate and vigorous PA. Only 11.2% and 27.4% reported no moderate or vigorous PA, respectively. Significant age and education gradients existed for both moderate and vigorous PA. An inverse association was noted between both moderate and vigorous PA guidelines and prevalence of chronic disease risk factors. Both frequency and duration of PA were required to adequately characterize the association between PA and health outcomes. Conclusions: These data demonstrate 1) greater prevalence of sufficient moderate and vigorous PA and lower prevalence of sedentary behavior in this sample compared with adults nationwide, 2) a greater association between vigorous PA and improved health outcomes than was observed for moderate PA, 3) PA guidelines must focus on both frequency and duration of activity, and 4) age and education gradients in moderate and vigorous PA that could have implications for more effective targeting of guidelines to improve the PA prevalence of American adults.
