Interventions for improving metabolic risk in overweight Latino youth.

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.

Inverse relation between dietary fiber intake and visceral adiposity in overweight Latino youth.

Background: To date, no studies have assessed the longitudinal changes of dietary intake on metabolic risk factors in Latino youth.

Objective: We assessed the relation between changes in dietary intake, specifically sugar and fiber intakes, with changes in adiposity and risk factors for type 2 diabetes in a longitudinal analysis of overweight Latino youth.

Design: Overweight Latino youth (n = 85; aged 11-17 y) underwent the following measures over 2 y [mean (+/-SD) time difference was 1.

Aerobic and strength training reduces adiposity in overweight Latina adolescents.

Purpose: To date, no study has examined the synergistic effects of a nutrition and combination of aerobic and strength training (CAST) on both adiposity and metabolic parameters in overweight Latina adolescent females. The goal was to assess if a 16-wk nutrition plus CAST pilot study had stronger effects on reducing adiposity and on improving glucose/insulin indices compared with control (C), nutrition only (N), and a nutrition plus strength training (N + ST) groups.

Methods: In a 16-wk randomized trial, 41 overweight Latina girls (15.

Association of breakfast skipping with visceral fat and insulin indices in overweight Latino youth.

Few studies have investigated the relationship between breakfast consumption and specific adiposity or insulin dynamics measures in children. The goal of this study is to determine whether breakfast consumption is associated with adiposity, specifically intra-abdominal adipose tissue (IAAT), and insulin dynamics in overweight Latino youth. Participants were a cross-sectional sample of 93 overweight (> or =85th percentile BMI) Latino youth (10-17 years) with a positive family history of type 2 diabetes.

Dietary intake and the metabolic syndrome in overweight Latino children.

Little is known about the relationship between diet and metabolic health in Latino children, a population at increased risk for diabetes. The present study evaluates diet composition and the metabolic syndrome in a cross-sectional sample of 109 overweight Latino children aged 10 to 17 years with a family history of type 2 diabetes. Dietary intake was assessed by two 24-hour recalls.

Associations of dietary sugar and glycemic index with adiposity and insulin dynamics in overweight Latino youth.

Background: Few studies have examined the relation between dietary carbohydrate quality, adiposity, and insulin dynamics in children.

Objective: The objective of the study was to determine which aspects of dietary carbohydrate, specifically dietary sugar, fiber, glycemic index, or glycemic load, are associated with adiposity and insulin dynamics in overweight Latino children.

Design: We examined 120 overweight Latino children (10-17 y old) with a family history of type 2 diabetes.

Feasibility of a home-based versus classroom-based nutrition intervention to reduce obesity and type 2 diabetes in Latino youth.

Objectives: The objectives of this pilot study were to compare the dietary, physiological and metabolic effects of 12-week modified carbohydrate nutrition intervention when disseminated in an individualized home-based format versus a group classroom-based format.

Methods: Twenty-three overweight (>/=85(th) percentile BMI) Latina adolescent females (12-17 years of age) were randomized to a 12-week modified carbohydrate dietary intervention delivered in either an individualized home-based format (n = 11) or a group classroom-based format (n = 12). Anthropometrics, dietary intake by 3-day diet records, insulin dynamics by extended 3-hour Oral Glucose Tolerance test (OGTT) and body composition by Dual energy X-ray absorptiometry (DXA) were measured before and after intervention; 24-hour diet recalls were collected once or twice per month throughout the program.
