背景。这项研究以 1,719 名随机选择的女性和男性为样本，研究了随时间推移采用和维持剧烈身体活动的预测因素。方法。根据基线时邮件调查中报告的剧烈运动频率，受试者被分为久坐运动（每周零次运动）、中等运动（每周一到两次运动）或活跃运动（每周三次或更多运动）。 结果。在同一调查中，受试者根据综合学习模型报告了 25 个体育活动的潜在决定因素。 24 个月后，85% 的受试者接受了重新调查，并对他们的身体活动水平进行了分类。在每个基线类别和性别亚组中，确定了后续身体活动的预测因素。在多变量分析中，久坐男性是否会进行剧烈运动是通过自我效能、年龄（逆）和邻里环境（逆）来预测的。久坐女性的接受程度是通过教育、自我效能以及朋友和家人对锻炼的支持来预测的。对于最初活跃的男性，通过自我效能和年龄（倒数）预测剧烈身体活动的维持；对于最初活跃的女性，通过教育来预测。结论。这些结果表明，影响男性和女性收养的因素是不同的，影响收养与维持剧烈身体活动的因素可能也不同。
Background. This study examined predictors of adoption and maintenance of vigorous physical activity over time in a sample of 1,719 randomly selected women and men.Methods. Based on reported frequency of vigorous exercise in a mail survey at baseline, subjects were classified as sedentary (zero sessions per week), intermediate (one to two sessions per week), or active (three or more sessions per week).Results. On the same survey subjects reported on 25 potential determinants of physical activity based on a comprehensive learning model. Twenty-four months later, 85% of subjects were resurveyed, and their physical activity levels were classified. Within each baseline category and gender subgroup, predictors of follow-up physical activity were identified. In multivariate analyses, adoption of vigorous exercise by sedentary men was predicted by self-efficacy, age (inverse), and neighborhood environment (inverse). Adoption by sedentary women was predicted by education, self-efficacy, and friend and family support for exercise. Maintenance of vigorous physical activity was predicted by self-efficacy and age (inverse) for initially active men and by education for initially active women.Conclusion. These results suggest that factors influencing adoption are different for men and women, and there may be different factors influencing adoption versus maintenance of vigorous physical activity.
