The main goal of this study was to analyze the associations between cardiorespiratory fitness (CRF) and body mass index (BMI) with self-rated health (SRH) of adolescent girls.
This was a cross-sectional study of 533 adolescents girls, aged from 10 to 18 years old. CRF was predicted by maximal multistage 20-m shuttle-run test according to procedures described from FITNESSGRAM. Girls' obesity status was classified according to International Obesity Task Force and Self-rated health (SRH) was assessed by questionnaire.
The findings showed that among adolescent girls 23.2% had negative SRH. Girls who were classified as unfit were more likely to report negative SRH in both univariate logistic (OR: 3.05; CI: 1.91-4.87; P < .05) and multivariate (OR: 2.93; CI: 1.82-4.72; P < .05) regression analyses compared with their fit peers. Obese girls were more likely to report negative SRH (OR: 2.30; CI: 1.14-4.62; P < .05) compared with their normal-weight counterparts. However such association was lost in multivariate analyses suggesting an effect of CRF.
Negative perception of health was associated with lower CRF and weight status although such association it is mediated by CRF condition.
本研究的主要目的是分析青少年女性的心肺适能（CRF）和体重指数（BMI）与自我报告健康（SRH）之间的关联。
这是一项横断面研究，共纳入 533 名年龄在 10 至 18 岁的少女。根据 FITNESSGRAM 描述的程序，最大多阶段 20 米穿梭跑测试预测 CRF。根据国际肥胖工作组（IOTF）的标准对女孩的肥胖状况进行分类，通过问卷评估自我报告健康（SRH）。
研究结果显示，在青少年女孩中，有 23.2%的人自我报告健康状况不佳。在单因素逻辑回归（OR：3.05；95%CI：1.91-4.87；P <.05）和多因素逻辑回归（OR：2.93；95%CI：1.82-4.72；P <.05）分析中，与健康的同龄人相比，被归类为不适合的女孩更有可能报告自我报告健康状况不佳。与正常体重的同龄人相比，肥胖女孩更有可能报告自我报告健康状况不佳（OR：2.30；95%CI：1.14-4.62；P <.05）。然而，在多因素分析中，这种关联消失了，提示 CRF 状态的影响。
负面的健康感知与较低的 CRF 和体重状况有关，尽管这种关联受到 CRF 状况的影响。
