Inadequate physical activity and obesity during adolescence are areas of public health concern. Questions exist about the role of neighborhoods in the etiology of these problems. This research addressed the relationships of perceived and objective reports of neighborhood crime to adolescent physical activity, screen media use, and body mass index (BMI).
Socioeconomically and racially/ethnically diverse adolescents (N = 2,455, 53.4% female) from 20 urban, public middle and high schools in Minneapolis/St. Paul, Minnesota responded to a classroom survey in the Eating and Activity in Teens 2010 study. BMI was measured by research staff. Participants' mean age was 14.6 (standard deviation = 2.0); 82.7% represented racial/ethnic groups other than non-Hispanic white. Linear regressions examined associations between crime perceived by adolescents and crime reported to police and the outcomes of interest (BMI z-scores, physical activity, and screen time). Models were stratified by gender and adjusted for age, race/ethnicity, socioeconomic status, and school.
BMI was positively associated with perceived crime among girls and boys and with reported crime in girls. For girls, there was an association between higher perceived crime and increased screen time; for boys, between higher reported property crime and reduced physical activity. Perceived crime was associated with reported crime, both property and personal, in both genders.
Few prior studies of adolescents have studied the association between both perceived and reported crime and BMI. Community-based programs for youth should consider addressing adolescents' safety concerns along with other perceived barriers to physical activity. Interventions targeting actual crime rates are also important.
青少年时期缺乏体育活动和肥胖是公共卫生关注的领域。关于社区在这些问题病因中的作用存在疑问。本研究探讨了青少年对社区犯罪的感知报告和客观报告与青少年体育活动、屏幕媒体使用及体重指数(BMI)之间的关系。
来自明尼阿波利斯/圣保罗市20所城市公立初中和高中的社会经济、种族/民族多样化的青少年(N = 2455,53.4%为女性)参与了2010年青少年饮食与活动研究中的课堂调查。BMI由研究人员测量。参与者的平均年龄为14.6岁(标准差 = 2.0);82.7%代表非西班牙裔白人以外的种族/民族群体。线性回归分析了青少年感知到的犯罪和向警方报告的犯罪与感兴趣的结果(BMI z评分、体育活动和屏幕时间)之间的关联。模型按性别分层,并对年龄、种族/民族、社会经济地位和学校进行了调整。
BMI与男孩和女孩感知到的犯罪呈正相关,与女孩报告的犯罪呈正相关。对于女孩,较高的感知犯罪与屏幕时间增加之间存在关联;对于男孩,较高的报告财产犯罪与体育活动减少之间存在关联。在两性中,感知到 的犯罪与报告的财产犯罪和人身犯罪均相关。
很少有针对青少年的先前研究探讨了感知到的犯罪和报告的犯罪与BMI之间的关联。以社区为基础的青少年项目应考虑在解决青少年对体育活动的其他感知障碍的同时,解决他们对安全的担忧。针对实际犯罪率的干预措施也很重要。
