背景身体活动不足导致美国青春期女孩超重和肥胖的高患病率。这项研究的三个目的是：(A)确定青春期阶段、种族/民族和社会经济地位(SES)障碍对PA的干扰程度的差异；(B)检查感知障碍与年龄、体重指数、娱乐屏幕时间、久坐活动和PA的关系；以及(C)确定女孩对PA最高的感知障碍。通过调查收集了人口统计学、青春期阶段、感知障碍和娱乐屏幕时间的数据。测量身高和体重。加速计测量了久坐活动、中等到剧烈的PA(MVPA)和轻度+MVPA。结果低SES的女孩比没有SES的女孩报告了更多的感知障碍对PA的干扰(1.16比0.97，p=。01)。青春期早、中期女孩的知觉障碍低于青春期晚期女孩(1.03比1.24，p<；001)。女生的知觉障碍与MVPA呈负相关(r=−)。10，p=.03)和光+MVPA(r=−。11，p=.02)。女孩感觉到的五大障碍包括缺乏技能、讨厌出汗、很难找到节目、疲倦和疼痛。讨论需要创新的干预措施，特别是关注技能发展，以帮助女孩克服感知到的PA障碍。
BackgroundInadequate physical activity (PA) contributes to the high prevalence of overweight and obesity among US adolescent girls. Barriers preventing adolescent girls from meeting PA guidelines have not been thoroughly examined.ObjectivesThe threefold purpose of this study was to (a) determine pubertal stage, racial/ethnic, and socioeconomic status (SES) differences in ratings of interference of barriers to PA;(b) examine relationships between perceived barriers and age, body mass index, recreational screen time, sedentary activity, and PA; and (c) identify girls’ top-rated perceived barriers to PA.MethodsGirls (N= 509) from eight Midwestern US schools participated. Demographic, pubertal stage, perceived barriers, and recreational screen time data were collected via surveys. Height and weight were measured. Accelerometers measured sedentary activity, moderate-to-vigorous PA (MVPA), and light plus MVPA.ResultsGirls of low SES reported greater interference of perceived barriers to PA than those who were not of low SES (1.16 vs. 0.97, p=. 01). Girls in early/middle puberty had lower perceived barriers than those in late puberty (1.03 vs. 1.24, p<. 001). Girls’ perceived barriers were negatively related to MVPA (r=−. 10, p=. 03) and light plus MVPA (r=−. 11, p=. 02). Girls’ top five perceived barriers included lack of skills, hating to sweat, difficulty finding programs, being tired, and having pain.DiscussionInnovative interventions, particularly focusing on skill development, are needed to assist girls in overcoming their perceived barriers to PA.
