Predictive value of physical fitness on self?rated health: A longitudinal study

Background The self-rated health of adolescents and young adults is important for estimating future morbidities mortality. Little known about how physical fitness in younger populations predicts health. This longitudinal study (2003-2017) aims to explore the effects on basis German population–based KiGGS its in-depth study, MoMo. Methods Self-rated was assessed using a one-item scale, measured with seven test items covering dimensions coordination, muscular fitness, cardiorespiratory fitness. Longitudinal analyses were conducted structural equation modeling approach Mplus 8.0 maximum likelihood estimator. Results samples KiGGS/MoMo (T1, n = 2376; T2, 2821; T3, 2047) had mean age 8.5, 14.8, 20.0 years at T1, respectively. All measurement models excellent model fits. While results latent regression analysis indicated moderate-to-high stability coordination dimensions, only low-to-moderate coefficients found Furthermore, small significant cross-lagged revealed that predicted later points. Conclusion To best our knowledge, this first demonstrate positive predictive value two stage. public implications are highlighted.
