Abstract

OBJECTIVE

To determine the efficacy of a 4-month school-based health, nutrition and exercise intervention on body fatness and examine possible effects of demographic and anthropometric covariates.

METHODS

Height, weight, waist circumference and body composition were measured in a diverse population of 644 NYC middle school students (mean ± SD age 12.7 ± 0.9 years; 46% male; 38% Hispanic, 17% East Asian, 15% South Asian, 13.5% African American, 8.5% Caucasian, 8% other) during the fall and spring semesters. Year 1 participants ( = 322) were controls. Experimental participants (year 2, = 469) received a 12-session classroom-based health and nutrition educational programme with an optional exercise intervention.

RESULTS

Groups were demographically and anthropometrically similar. The intervention resulted in significant reductions in indices of adiposity (ΔBMI -scores [-0.035 ± 0.014; = 0.01], Δ% body fat [-0.5 ± 0.2; < 0.0001] and Δwaist circumference [-0.73 ± 0.30 cm; < 0.0001]). Intervention effects were greater ( = 0.01) in men (ΔBMI -score = -0.052 ± 0.015) versus women (0.022 ± 0.018), participants who were obese (ΔBMI -score -0.083 ± 0.022 kg m) versus lean (-0.0097 ± 0.020 kg m) and South Asians (Δ% body fat -1.03 ± 0.35) versus total (-0.49 ± 0.20%) participants ( = 0.005).

CONCLUSION

A 4-month school-based health intervention was effective in decreasing measures of adiposity in middle school students, particularly in men, participants who were obese and South Asians.

摘要

目的

确定一项为期4个月的以学校为基础的健康、营养和运动干预对身体脂肪含量的疗效，并研究人口统计学和人体测量学协变量可能产生的影响。

方法

在秋季和春季学期对644名纽约市中学生（平均年龄±标准差为12.7±0.9岁；46%为男性；38%为西班牙裔，17%为东亚裔，15%为南亚裔，13.5%为非裔美国人，8.5%为白种人，8%为其他种族）这一多样化群体测量身高、体重、腰围和身体成分。第一年的参与者（n = 322）为对照组。实验参与者（第二年，n = 469）接受了一个为期12节的以课堂为基础的健康和营养教育项目，并可选择进行运动干预。

结果

两组在人口统计学和人体测量学方面相似。干预导致肥胖指标显著降低（ΔBMI评分[-0.035±0.014；P = 0.01]，Δ体脂百分比[-0.5±0.2；P < 0.0001]和Δ腰围[-0.73±0.30厘米；P < 0.0001]）。男性（ΔBMI评分=-0.052±0.015）的干预效果大于女性（0.022±0.018）（P = 0.01），肥胖参与者（ΔBMI评分-0.083±0.022 kg/m²）大于瘦参与者（-0.0097±0.020 kg/m²）（P = 0.01），南亚裔参与者（Δ体脂百分比-1.03±0.35）大于全体参与者（-0.49±0.20%）（P = 0.005）。
