关于西班牙裔青少年体力活动和久坐行为的相关性知之甚少。本研究在基线和2年随访时检查了：（1）身体活动自我效能与身体活动之间的关系，（2）体重感知与身体活动和久坐行为的关联，以及（3）性别是否调节了这些关联。西班牙裔青少年（基线时N = 483;年龄15-17岁; 55.1%为女孩）完成了问卷调查，评估了他们对体力活动、体重感知以及体力活动和久坐行为的自我效能。进行多组路径分析，以检查拟议的关系，并确定它们是否由性别调节。模型控制体重指数，减肥意图，参加运动队，在家里说的语言，父母的教育，和出生国。自我效能感与男孩（B = 0.35，p <0.001）和女孩（B = 0.41，p <0.001）在基线时的体力活动时间有关，但在2年后则无关。没有发现体重感知与体力活动和久坐行为的时间相关。对基线超重参与者的事后分析表明，体重感知与看电视的时间有关。总的来说，研究结果表明，自我效能是一个重要的相关性，但不是预测，西班牙裔青少年的身体活动。在生活方式干预措施中纳入解决和增强身体活动自我效能的策略，可能会增加对身体活动建议的坚持，并有助于降低这一人群的肥胖率。
Little is known about the correlates of physical activity and sedentary behavior in Hispanic adolescents. This study examined at baseline and 2-year follow-up: (1) the relationship between self-efficacy for physical activity and physical activity, (2) the association of weight perception with physical activity and sedentary behavior, and (3) whether sex moderated these associations. Hispanic adolescents (N = 483 at baseline; age 15-17 years; 55.1% girls) completed questionnaires that assessed their self-efficacy for physical activity, weight perception, and time spent in physical activity and sedentary behavior. Multiple-group path analyses were conducted to examine the proposed relationships and determine whether they were moderated by sex. Models controlled for body mass index, weight loss intention, participation on a sports team, language spoken at home, parental education, and country of birth. Self-efficacy was related to time spent in physical activity in boys (b = .35, p < .001) and girls (b = .41, p < .001) at baseline, but not 2 years later. No association was found for weight perception and time spent in physical activity and sedentary behavior. Post hoc analyses for overweight participants at baseline showed that weight perception was associated with time spent watching television. Overall, the findings suggest that self-efficacy is an important correlate, but not a predictor, of physical activity among Hispanic adolescents. Including strategies to address and enhance self-efficacy for physical activity in lifestyle interventions may increase adherence to physical activity recommendations and help reduce the high prevalence of obesity in this population.
