Objectives

To analyze the independent and combined associations of physical activity (PA) and sedentary behavior (SB) with self-rated health (SRH) in a large sample of adolescents.

Methods

Data from 100,873 students with mean age of 14.3 (±1.1) years were analyzed. SRH, PA and SB were assessed by questionnaires. Age, ethnicity, maternal education, geographical region of country, type of city, industrialized and sugary foods consumption were covariates. Logistic regression models were used to analyze the data according to gender.

Results

≥300 min/week of PA [OR:1.12 (95%CI:1.04–1.21)] and <4 h of sitting time [OR:1.42 (95%CI:1.32–1.54)] were associated with good SRH among boys, while only lower sitting time was associated with good SRH among girls [OR:1.32 (95%CI:1.23–1.41)]. Physically active and with low sitting time adolescents were more likely to have good SRH [Boys OR:1.57 (95%CI:1.41–1.75); Girls OR:1.32 (95%CI:1.18–1.46)], than inactive and with high sitting time counterparts. However, high sitting time was associated with poor SRH independently of ≥300 min/week of PA.

Conclusion

PA and sitting time were independently associated with SRH in Brazilian adolescents. Moreover, reaching ≥300 min/week of PA was not sufficient to attenuate the negative association between high sitting time and SRH.

自我评估的健康状况不佳与久坐行为有关，无论青少年是否进行体育锻炼-PeNSE研究。

目标

分析大量青少年样本中的体育活动（PA）和久坐行为（SB）与自评健康（SRH）的独立和组合关联。

方法

分析了来自100873名平均年龄为14.3（±1.1）岁的学生的数据。通过问卷调查对SRH，PA和SB进行评估。年龄，种族，母亲教育，国家地理区域，城市类型，工业化和含糖食品的消费是协变量。使用Logistic回归模型根据性别分析数据。

结果

≥300分钟/周的PA [OR：1.12（95％CI：1.04–1.21）]和<4小时的坐着时间[OR：1.42（95％CI：1.32-1.54）]与男孩的SRH良好相关，而女生只有较短的就座时间与良好的SRH相关[OR：1.32（95％CI：1.23-1.41）]。参加体育锻炼且坐姿时间短的青少年更有可能具有良好的SRH [男孩OR：1.57（95％CI：1.41-1.75）；女孩OR：1.32（95％CI：1.18–1.46）]，比不活跃的人和坐着时间长的人高 但是，高坐位时间与SRH差有关，而与PA≥300分钟/周无关。

结论

PA和坐时间与巴西青少年的SRH独立相关。此外，达到≥300分钟/周的PA不足以减轻高坐位时间与SRH之间的负相关性。
