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 VOmax (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).

摘要

背景

过度的屏幕时间（ST）和较低的体力活动（PA）模式已被报道对心脏代谢风险（CMR）有影响；然而，它们对身体健康的影响需要深入研究。

目的

确定智利学童的生活方式（即放学后的 ST 和 PA）与与健康和 CMR（即腹部肥胖和高血压）相关的身体健康之间的关联。

方法

本横断面研究的样本包括 263 名女孩（11.87±0.83 岁）和 319 名男孩（12.02±0.88 岁）。评估了体重指数（BMI）、腰围（WC）、腰高比（WtHR）、CMR（WtHR≥0.5）、体脂肪（BF）、收缩压（SBP）和舒张压（DBP）、身体适能、ST（h/天）和放学后的 PA（h/周）。

结果

生活方式良好的学童 BMI、WC 和 WtHR 较低（P<0.001），最大摄氧量（VOmax）和立定跳远测试（SLJ）更好（P<0.001）。生活方式不良的学童有最高比例的腹部肥胖（WtHR≥0.5）（30.6%，P=0.009）和高血压（40.9%，P<0.001）。同样，PA 放学后（β；-0.02，P=0.002）和调整年龄和性别后的心肺适能（β；-0.02，P=0.002）与腹部肥胖（WtHR≥0.5）呈负相关。同样，ST 与 SBP 呈正相关（β；0.14，P=0.030）。此外，握力（β；-0.17，P=0.010）和 SLJ（β；-0.05，P=0.023）与 SBP 呈负相关。
