This review highlights various components of interventions that reduced obesity and type 2 diabetes risk factors among overweight Latino youth. A total of 114 overweight Latino adolescents completed one of four randomized controlled trials: 1) strength training (ST; boys only); 2) modified carbohydrate nutrition program (N); 3) combination of N+ST; or 4) N + Combination of Aerobic and ST (N+CAST; girls only). Measures included: strength by 1-repetition max, dietary intake by 3-d records, body composition by DEXA/MRI, glucose/insulin indices by oral and IV glucose tolerance tests. ST improved insulin sensitivity by 45% in Latino boys, and N, N+ST, and N+CAST improved glucose control in Latino boys and girls. The CAST approach reduced all adiposity measures by ∼3% in Latina girls. Participants who decreased added sugar, increased dietary fiber, and had increased parental attendance, regardless of intervention group, improved insulin action and reduced visceral adipose tissue. In conclusion, ST, CAST, and a modified carbohydrate nutrition program with separate parental classes were all successful components of the interventions that decreased obesity and related metabolic diseases.
本综述重点介绍了各种干预措施的组成部分，这些措施降低了超重拉丁裔青少年肥胖和2型糖尿病风险因素。共有114名超重拉丁裔青少年完成了四项随机对照试验之一：1）力量训练（ST；仅针对男孩）；2）改良碳水化合物营养计划（N）；3）N+ST组合；或4）N+有氧和力量训练组合（N+CAST；仅针对女孩）。测量指标包括：通过1次重复最大值测量力量，通过3天记录测量饮食摄入量，通过双能X线吸收法/磁共振成像测量身体成分，通过口服和静脉葡萄糖耐量试验测量葡萄糖/胰岛素指标。力量训练使拉丁裔男孩的胰岛素敏感性提高了45%，而营养计划、营养计划+力量训练以及营养计划+有氧和力量训练组合均改善了拉丁裔男孩和女孩的血糖控制。有氧和力量训练组合方法使拉丁裔女孩的所有肥胖指标降低了约3%。无论干预组如何，减少添加糖、增加膳食纤维并提高家长参与度的参与者改善了胰岛素作用并减少了内脏脂肪组织。总之，力量训练、有氧和力量训练组合以及带有单独家长课程的改良碳水化合物营养计划都是降低肥胖及相关代谢疾病的成功干预措施组成部分。
