Associations between self-rated health with cardiorespiratory fitness and obesity status among adolescent girls
Background: 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. Methods: 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. Results: 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. Conclusions: Negative perception of health was associated with lower CRF and weight status although such association it is mediated by CRF condition.
