abstract = {: Self-rated health (SRH) is an independent determinant for all-cause mortality. We aimed to
examine the independent and combined associations of components of physical fitness with SRH
at baseline (cross-sectional) and two years later (longitudinal) in children and adolescents. Spanish
youth (N = 1378) aged 8 to 17.9 years participated at baseline. The dropout rate at 2-year follow-up was
19.5% (n = 270). Participants were categorized as either children (8 to 11.9 years age) or adolescents (12
to 17.9 years age). The ALPHA health- related fitness test battery for youth was used to assess physical
fitness, and SRH was measured by a single-item question. Cumulative link, ANOVA and ANCOVA
models were fitted to analyze the data. Cardiorespiratory fitness, relative upper body isometric
muscular strength, muscular strength score, and global physical fitness were positively associated
with SRH in children (OR, 1.048; 95% CI, 1.020–1.076; OR, 18.921; 95% CI, 3.47–104.355; OR, 1.213;
95% CI, 1.117–1.319, and OR, 1.170; 95% CI, 1.081–1.266, respectively; all p < 0.001) and adolescents
(OR, 1.057; 95% CI, 1.037–1.076; OR, 5.707; 95% CI, 1.122–29.205; OR, 1.169; 95% CI, 1.070–1.278, and
OR, 1.154 95% CI, 1.100–1.210, respectively; all p < 0.001); and motor fitness was positively associated
with SRH only in adolescents at baseline (OR, 1.192; 95% CI, 1.066–1.309; p < 0.01). Cardiorespiratory
fitness and global physical fitness were positively associated with SRH in children two years later
(OR, 1.056; 95% CI, 1.023–1.091; p < 0.001; and OR, 1.082; 95% CI, 1.031–1.136; p < 0.01; respectively).
Only cardiorespiratory fitness was independently associated with SRH in children and adolescents
at baseline (OR, 1.059; 95% CI, 1.029–1.090; and OR, 1.073; 95% CI, 1.050–1.097, respectively; both
p < 0.001) and two years later (OR, 1.075; 95% CI, 1.040–1.112; p < 0.001; and OR, 1.043; 95% CI,
1.014–1.074; p < 0.01, respectively). A high level of cardiorespiratory fitness at baseline or maintaining
high levels of cardiorespiratory fitness from the baseline to 2-year follow-up were associated with a
higher level of SRH at 2-year follow-up in children (p < 0.01) and adolescents (p < 0.05). These findings
emphasize the importance of cardiorespiratory fitness as strong predictor of present and future SRH
in youth. Intervention programs to enhance cardiorespiratory fitness level of the youth population
are urgently needed for present and future youth’s health.},
