Abstract
BACKGROUND: Excessive screen time (ST) and lower physical activity (PA) patterns have been reported to have an impact on cardiometabolic risk (CMR); however, their impact on physical fitness needs in-depth study. OBJECTIVE: To determine the association between lifestyle (i.e. ST and PA after school) with physical fitness related to health and CMR (i.e. abdominal obesity and hypertension) in Chilean schoolchildren. METHODS: The sample for this cross-sectional study comprised 263 girls (11.87±0.83 years) and 319 boys (12.02±0.88 years). The body mass index (BMI), waist circumference (WC), waist to height ratio (WtHR), CMR (WtHR≥0.5), body fat (BF), systolic (SBP) and diastolic blood pressure (DBP), physical fitness, ST (h/day), and PA after school (h/week) were evaluated. RESULTS: Schoolchildren with good lifestyle had a lower BMI, WC, and WtHR (P<0.001) as well as a better VO2max (P<0.001) and standing long jump test (SLJ) (P=0.002). The schoolchildren with bad lifestyle had the highest proportion of students with abdominal obesity (WtHR≥0.5) (30.6%, P=0.009) and hypertension. (40.9%, P<0.001). Likewise, PA after school (β; -0.02, P=0.002) and cardiorespiratory fitness (β; -0.02, P=0.002) adjusted by age and sex reported inverse associations with abdominal obesity (WtHR≥0.5). Likewise, ST presented a positive association with SBP (β; 0.14, P=0.030). Moreover, handgrip strength (β; -0.17, P=0.010) and SLJ (β; -0.05, P=0.023) reported inverse associations with SBP. CONCLUSION: In schoolchildren, a bad lifestyle was associated with low physical fitness related to health and CMR (i.e. abdominal obesity and hypertension).
