OBJECTIVE
The design of effective obesity interventions to reduce adiposity and increase fitness in minority children is a public health priority. This study assessed the effectiveness of a summer intervention in lowering adiposity and increasing aerobic endurance in minority girls.
METHODS
99 Hispanic and African American girls and their mothers participated. During the intervention, girls attended daily exercise, nutrition education, and counseling sessions from 9:00 AM to 5:00 PM. Mothers attended 2-h weekly exercise, nutrition, and counseling sessions. Percent body fat, abdominal fat, and aerobic endurance (1-mile run/walk minutes) data were collected at pre- and post-intervention.
RESULTS
A repeated-measures analysis of variance was used to test differences in adiposity indicators and aerobic endurance. Findings indicated statistically significant reductions in percent body fat (p < .001), abdominal fat (p < .001), and 1-mile run/walk minutes (p < .001).
CONCLUSIONS
This study demonstrated the effectiveness of a summer intervention in reducing adiposity indicators and increasing aerobic endurance.
目的
设计有效的肥胖干预措施，以降低少数族裔儿童的肥胖率并提高其健康水平，这是公共卫生的重点。本研究评估了一项暑期干预措施在降低少数族裔女孩肥胖率和提高其有氧耐力方面的有效性。
方法
99 名西班牙裔和非裔美国女孩及其母亲参与了该研究。在干预期间，女孩们从上午 9 点到下午 5 点参加每日的锻炼、营养教育和咨询课程。母亲们则参加每周 2 小时的锻炼、营养和咨询课程。在干预前后收集了身体脂肪百分比、腹部脂肪和有氧耐力（1 英里跑/走时间）的数据。
结果
采用重复测量方差分析来检验体脂指标和有氧耐力的差异。研究结果表明，身体脂肪百分比（p<.001）、腹部脂肪（p<.001）和 1 英里跑/走时间（p<.001）均有统计学意义的降低。
结论
本研究表明，暑期干预措施在降低体脂指标和提高有氧耐力方面是有效的。
