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.

Nonalcoholic fatty liver disease (NAFLD) is one of the most frequent complications associated with excess adiposity. Its pathogenesis is complex and there are multiple factors that may contribute to it. AIM: To analyze whether cardiorespiratory fitness (CRF), waist circumference (WC), and C-reactive protein (CRP) are associated with alanine aminotransferase (ALT) in children with obesity. METHODS: 79 overweight/obese children of both genders, 11–13 year-olds, with abnormal serum ALT from Porto public schools comprised the sample. Measurements included CRF (20-m Shuttle Run Test), WC (NHANES protocol), CRP and ALT (Cholestech LDX analyzer). Logistic regression adjusted for gender, maturation, and weight with ALT levels as dependent variable (risk vs. non risk), and WC (risk vs. non risk), CRP (risk vs. non risk), and CRF (fit vs. unfit) as independent variables. Level of significance was set at 95%. RESULTS: Logistic regression showed that obese fit children were less likely to have abnormal ALT values (OR=.031) CONCLUSION: In obese children, higher cardiovascular fitness appears to reduce the chance of decreased liver function.

This study analyzes trends in CVD risk factors and aerobic performance. Two cross-sectional studies were performed including 138 (58 boys and 80 girls) in 1998 and 110 (44 boys and 66 girls) in 2003 adolescents. Although in cardiorespiratory fitness (CRF) boys performed better than girls, they had lower body mass index (BMI) and total cholesterol (TC) than girls. The data also showed a significant year effect (p = .000) for CRF in both boys and girls. The sex–age group interaction was not significant (p > .05). This cross-sectional study revealed a marked low CRF level over time in both boys and girls.
