To estimate the prevalence of moderate and vigorous physical activity (MVPA), as defined by the World Health Organisation (WHO), and associated factors among teenagers from Barcelona in 2012.
Cross-sectional survey to assess risk factors in a representative sample of secondary school students (aged 13-16 years, International Standard Classification of Education [ISCED] 2, n=2,162; and 17-18 years, ISCED 3, n=1016) in Barcelona. We estimated MVPA prevalence overall, and for each independent variable and each gender. Poisson regression models with robust variance were fit to examine the factors associated with high-level MVPA, and obtained prevalence ratios (PR) and 95% confidence intervals (95%CI).
Only 13% of ISCED 2 and 10% of ISCED 3 students met the WHO physical activity recommendations. This percentage was lower among girls at both academic levels. MVPA was lower among ISCED 3 compared to ISCED 2 students, and among students with a lower socioeconomic status. Physical activity was associated with positive self-perception of the health status (e.g., positive self-perception of health status among ISCED 2 compared to ISCED 3 students: PR=1.31 [95%CI: 1.22-1.41] and 1.61 [95%CI: 1.44-1.81] for boys and girls, respectively].
The percentage of teenagers who met WHO MVPA recommendations was low. Strategies are needed to increase MVPA levels, particularly in older girls, and students from low socioeconomic backgrounds.
评估2012年巴塞罗那青少年中符合世界卫生组织（WHO）定义的中等强度和剧烈身体活动（MVPA）的患病率及其相关因素。
采用横断面调查，对巴塞罗那具有代表性的中学生样本（13 - 16岁，国际教育标准分类[ISCED]2，n = 2162；17 - 18岁，ISCED 3，n = 1016）进行危险因素评估。我们总体上估计了MVPA患病率，并针对每个自变量和每个性别进行了估计。采用具有稳健方差的泊松回归模型来检验与高水平MVPA相关的因素，并获得患病率比（PR）和95%置信区间（95%CI）。
只有13%的ISCED 2学生和10%的ISCED 3学生符合WHO身体活动建议。在两个学业水平的女生中，这一比例更低。与ISCED 2学生相比，ISCED 3学生的MVPA水平更低，社会经济地位较低的学生也是如此。身体活动与对健康状况的积极自我认知相关（例如，与ISCED 3学生相比，ISCED 2学生中对健康状况的积极自我认知：男生和女生的PR分别为1.31[95%CI：1.22 - 1.41]和1.61[95%CI：1.44 - 1.81]）。
符合WHO MVPA建议的青少年比例较低。需要采取策略来提高MVPA水平，特别是在年龄较大的女孩和社会经济背景较低的学生中。
