Abstract

BACKGROUND

Public school children regularly participate in school-based physical activity, physical education, and fitness testing. However, almost 2 million American children are homeschooled. The purpose of this research was to assess the body composition of elementary school-aged homeschool children and their corresponding cardiovascular disease (CVD) risk.

METHODS

This research explored the body composition and CVD risk of 145 homeschool children aged 5-11 years using body mass index (BMI), percent body fat, and waist circumference. Chi-square and Mann-Whitney U tests examined differences in CVD risk within the homeschool population.

RESULTS

Overall, homeschool children had average BMI z-scores (SD [range]) with a mean of -0.11 (0.97 [-3.47 to 2.53]). Unhealthy classifications were seen in 11.2% of the sample by BMI, 19.6% by percent body fat, and 49.7% by waist circumference. Statistical analysis revealed no difference in CVD risk between sexes (χ (1) = 0.062, p = .804) or ethnicities (χ (1) = 0.927, p = .336) but increased prevalence in children aged 5-9 years (U = 1427, z = -4.559, p < .001).

CONCLUSIONS

Almost half of elementary school-aged homeschool children showed increased risk for CVD and need regular assessment of central adiposity.

摘要

背景

公立学校的儿童经常参加学校内的体育活动、体育课和体能测试。然而，近 200 万美国儿童是在家接受教育的。本研究的目的是评估小学年龄在家上学儿童的身体成分及其相应的心血管疾病 (CVD) 风险。

方法

本研究使用身体质量指数 (BMI)、体脂肪百分比和腰围，探讨了 145 名 5-11 岁在家上学儿童的身体成分和 CVD 风险。卡方检验和曼-惠特尼 U 检验检查了在家上学人群中 CVD 风险的差异。

结果

总体而言，在家上学的儿童 BMI z 分数（标准差 [范围]）平均值为-0.11（0.97 [-3.47 至 2.53]）。根据 BMI，样本中有 11.2%的人属于不健康分类，19.6%的人属于体脂肪百分比不健康，49.7%的人属于腰围不健康。统计分析显示，性别（χ (1) = 0.062，p = 0.804）或种族（χ (1) = 0.927，p = 0.336）之间的 CVD 风险无差异，但 5-9 岁儿童的患病率增加（U = 1427，z = -4.559，p < 0.001）。
