目标。对于文化适应如何影响青少年参加业余体育活动和肥胖，我们知之甚少。本研究的目的是在西班牙裔青少年中检验这些关联。设计。数据来自2003年全国儿童健康调查，仅限于10-17岁的西班牙裔青少年（n=4704）。文化适应是通过代理措施（世代地位和在家里使用的语言）来评估的。据报道，青少年每周至少有三天没有进行持续至少20分钟、足以导致出汗和呼吸困难的体力活动，就被定义为没有达到体力活动要求。肥胖被定义为性别和年龄特定的体重指数值等于或高于参考人群的第95个百分位数。进行多重逻辑回归以调整混杂因素。结果。在研究的西班牙裔青少年中，分别有25.2%，43.8%和31.1%是第一代，第二代和第三代或更多。42.8%的青少年在家中以英语为主要语言。与第三代青少年相比，来自移民家庭的青少年不参加推荐的体育活动的几率更高（第一代：调整优势比[AOR] = 1.50, 95%会议间隔[CI]: 1.09, 2.05；第二代：AOR = 1.29, 95% CI: 0.99, 1.69）。与以英语为主要语言的家庭相比，生活在英语为主要语言的家庭中，也与没有获得推荐的身体活动有关（AOR = 1.36, 95% CI: 1.06, 1.75）。在英语不是主要语言的家庭中，未调整的肥胖患病率更高（22.5%比16.1%;p0.01），但在调整了家庭社会经济地位后，这种差异消失了。代际地位与肥胖没有显著相关性。结论。研究结果表明，未来旨在增加西班牙裔青少年体育活动的公共卫生干预措施应根据代际地位和英语使用情况进行调整。
Objective. Little is known about how acculturation may influence participation in leisure-time physical activity and obesity among adolescents. The objective of this study was to examine these associations among Hispanic adolescents. Design. Data were drawn from the 2003 National Survey of Children's Health, restricted to Hispanic adolescents aged 10-17 (n=4704). Acculturation was assessed by proxy measures (generation status and language spoken at home). Adolescents who were not reported to engage in physical activity lasting at least 20 minutes, that was vigorous enough to cause sweating and hard breathing, for at least three days per week were defined as failing to meet physical activity requirements. Obesity was defined as gender and age-specific body mass index values at or above the 95th percentile of the reference population. Multiple logistic regressions were performed to adjust for confounders. Results. Of the Hispanic adolescents studied, 25.2%, 43.8%, and 31.1% were first, second, and third generation or more, respectively. English was the primary language in the home for 42.8% of these adolescents. Compared with adolescents in the third generation, adolescents from immigrant families had higher odds for not obtaining recommended physical activity (first generation: adjusted odds ratio [AOR] = 1.50, 95% conference intervals [CI]: 1.09, 2.05; second generation: AOR = 1.29, 95% CI: 0.99, 1.69). Living in homes where English was not the primary language, vs. English-speaking homes, was also associated with not obtaining recommended physical activity (AOR = 1.36, 95% CI: 1.06, 1.75). The unadjusted prevalence of obesity was higher in homes where English was not the primary language (22.5% vs. 16.1%; p0.01), but this difference disappeared after adjusting for family socioeconomic status. Generational status was not a significant correlate of obesity. Conclusions. Findings suggest that future public health interventions that aim to increasing physical activity among Hispanic adolescents should be tailored based on generational status and English-language use.
