Low levels of physical activity (PA) are associated with persistent obesity. Adolescent obesity is linked to adult morbidity and premature mortality. This study examined a model of perceived parental influence in Mexican older adolescents to uncover contemporaneous family and personal predictors of Mexican older adolescents' PA.
Participants 16- to 25-years-old (n = 3,908), Mexican college applicants, underwent a health screen and filled out questionnaires which included information on PA and potential correlates. A logistic regression model was used to ascertain family factors (socioeconomic status, conflict about PA, and perceived parental PA) and individual factors (age, sex, body mass index, depressive symptoms, enjoyment of PA, and sedentary behaviors) associated with adolescents' PA.
Most participants reported being physically active (61.5%); less than half reported physically active parents (40.0%). Perceived parental PA (odds ratio [OR] = 8.67, p ≤ .0001), enjoyment of PA (OR = 2.11, p ≤ .0001), and conflicts about PA (OR = 1.16, p ≤ .0001) were important positive predictors of adolescents' PA.
PA among Mexican older adolescents is influenced by parental PA. The role of conflicts about PA is likely to be influenced by culture and may indicate that older adolescents' PA is not completely accepted by parents.
低水平的身体活动（PA）与持续肥胖有关。青少年肥胖与成年人发病率和过早死亡有关。本研究通过调查感知到的父母对墨西哥大龄青少年的影响模型，揭示了当前家庭和个人因素对墨西哥大龄青少年 PA 的预测作用。
参与者为 16 至 25 岁（n=3908）的墨西哥大学生申请者，他们接受了健康检查并填写了问卷，其中包括 PA 及潜在相关因素的信息。采用逻辑回归模型确定与青少年 PA 相关的家庭因素（社会经济地位、PA 冲突和感知到的父母 PA）和个人因素（年龄、性别、体重指数、抑郁症状、对 PA 的享受和久坐行为）。
大多数参与者报告身体活跃（61.5%）；不到一半的人报告父母身体活跃（40.0%）。感知到的父母 PA（优势比[OR] = 8.67，p ≤.0001）、对 PA 的享受（OR = 2.11，p ≤.0001）和 PA 冲突（OR = 1.16，p ≤.0001）是青少年 PA 的重要积极预测因素。
墨西哥大龄青少年的 PA 受到父母 PA 的影响。关于 PA 的冲突的作用可能受到文化的影响，这表明大龄青少年的 PA 并没有完全被父母所接受。
