Abstract
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.
Highlights
Latino youth are 1.5–1.7 times more likely to be obese than Caucasian children, with 40.5% and 37.1% of Latino boys and girls, respectively, being overweight (Ն85th CDC ageand gender-specific percentile) compared with 34.5% and 31.7%, respectively, of Caucasian children being overweight [1,2]
Several components from the above interventions resulted in significant reductions in adiposity and type 2 diabetes risk factors in overweight Latino youth
The CAST approach resulted in significant reductions in all adiposity measures in Latina girls.The location of the nutrition intervention did not affect health outcomes
Summary
Latino youth are 1.5–1.7 times more likely to be obese than Caucasian children, with 40.5% and 37.1% of Latino boys and girls, respectively, (aged 12 to 19 years) being overweight (Ն85th CDC ageand gender-specific percentile) compared with 34.5% and 31.7%, respectively, of Caucasian children being overweight [1,2]. While there are numerous pediatric interventions aimed at decreasing obesity [8,9], few randomized trials have targeted Latinos or addressed the underlying metabolic abnormalities, visceral fat, insulin secretion and resistance. One of the few interventions conducted in Latino youth was the Bienstar Program, which was a large school-based, randomized control trial with 3 096 4th grade students, who were 80% Latino and 94% low socioeconomic status. This 7-month intervention focused on decreasing fat intake and increasing dietary fiber and physical activity, resulted in significant reductions in fasting glucose levels (adjusted difference of −2.24 mg/dL) compared with control schools [10]. A recent school-based randomized control trial with 60 overweight Latino children (aged 10–14 years), found that an intensive 12-week
