    The objective of this study was to determine the predictive value of different measures of physical literacy (PL) on cardio- metabolic risk in adolescents with abdominal obesity. Method. A cross-sectional, descriptive, and analytical study was con- ducted with a sample of 51 abdominal obesity male adolescents aged 11–15 years. Cardiometabolic risk was estimated using the MetS-score, based on anthropometric, biochemical, and blood pressure data. LASSO regression models were applied to identify the predictive value of PL measures on cardiometabolic risk outcomes. Results. The study findings showed that the physical dimension of PL has measures that moderately predict (f2=0.17), 14.5% of the variance in cardiometabolic risk through the MetS-score. In addition, PL measures were selected to explain other components of cardiometabolic risk, with a large effect on waist circumference and systolic and diastolic blood pressure (f2=3.379; f2=0.771; f2=0.472, respectively). Conclusion. The results of this study show that the physical dimension of PL can predict MetS-scores in abdominal obesity adolescents. Furthermore, it was identified that the psychological and cognitive dimensions of PL, although they do not directly predict the MetS-score, play a relevant protective role in blood pressure and, to a lesser extent, in waist circumference.

    Background: Chile is one of the countries with the lowest indicators of children’s physical activity therefore it is necessary to promote the development of factors that encourage regular practice, such as motor competence (MC), which is considered a fundamental factor in improving physical activity trajectories in school-age children. This CoMoSur study aimed to determine the prevalence of MC in fifth- and sixth-grade primary school children in central-southern Chile and analyze the association of MC with sex, age, and weight status. Methods: The MC of 1513 schoolchildren (49.4% girls; mean = 11.12 y, SD = 0.92) from 7 regions of central-southern Chile was assessed using the MOBAK 5-6 test. Confirmatory factor analyses and structural equation models were applied to test 2 models: (1) the factorial validity of the 2 dimensions of MC (object control and self-movement) and (2) the associations of MC with sex, age, and weight status. Results: Low levels of MC were observed, especially in girls. Model 1 showed adequate fit indices ( χ 2  = 64.912, df = 19, P  ≤ .001, CFI = .975, TLI = .963, RMSEA = .040, SRMR = .035). Model 2 also presented satisfactory fit ( χ 2  = 161.97, df = 37, P  ≤ .001, CFI = .943, TLI = .920, RMSEA = .047, SRMR = .071), revealing significant associations: sex is associated with both object control and self-movement, age was positively related to both MC dimensions, and higher weight status was negatively associated with MC. Conclusions: The MC levels in Chilean schoolchildren are concerning, underlining the urgency of implementing intervention programs to strengthen motor competencies. Such strategies should consider differences in sex, age, and weight status to promote sustainable trajectories of physical activity from childhood onward.
