Thesis (Ph.D.)--University of Southern California, 2009.

One third of overweight Latino youth have the metabolic syndrome, a clustering of risk factors for diabetes and cardiovascular disease. The objectives of this dissertation were: (1) to examine the association between dietary intake and the metabolic syndrome with a focus on the quality of carbohydrate intake; (2) to examine whether persistent metabolic syndrome over 3 annual visits was associated with increased risk for type 2 diabetes; and (3) to test the effects of a randomized, controlled, 16 week, modified-carbohydrate nutrition education program on metabolic syndrome profiles.

520 $a One third of overweight Latino youth have the metabolic syndrome, a clustering of risk factors for diabetes and cardiovascular disease. The objectives of this dissertation were: (1) to examine the association between dietary intake and the metabolic syndrome with a focus on the quality of carbohydrate intake; (2) to examine whether persistent metabolic syndrome over 3 annual visits was associated with increased risk for type 2 diabetes; and (3) to test the effects of a randomized, controlled, 16 week, modified-carbohydrate nutrition education program on metabolic syndrome profiles.
520 $a All participants were Latino and had BMI ≥ 85th percentile. Data for papers 1 and 2 are from a longitudinal, observational study for children ages 10-17 years, and data for paper 3 is from a 16 week intervention study for adolescents ages 14-18 years. The metabolic syndrome was defined by a pediatric adaptation of the Adult Treatment Panel III report. Body composition was assessed by DEXA, and insulin/glucose kinetics by OGTT and IVGTT. Dietary intake was assessed by 24 hour recalls in paper 1 and by 3 day diet records in paper 3.
520 $a In paper 1, participants with 0 features of the metabolic syndrome ate significantly more soluble fiber compared to those with 3+ features of the metabolic syndrome (5g vs. 4g daily). In paper 2, when compared with participants who never had the metabolic syndrome, participants with persistent metabolic syndrome had a faster rate of fat mass gain over time and an increasing level of insulin response to oral glucose, combined with an average of 43% lower insulin sensitivity, and 25% lower beta cell function. In paper 3, the intervention had few improvements on metabolic syndrome profiles. However, independent of randomiztion group, those who increased fiber intake (average of 6g/day) had a decrease in the number of metabolic syndrome features.
520 $a In conclusion, cross-sectionally, soluble fiber intake was the only dietary variable significantly associated with the metabolic syndrome. Longitudinally, persistent metabolic syndrome was associated with indicators of increased risk for type 2 diabetes. Finally, in the context of a 16 week intervention, increases in fiber intake are related to improvements in metabolic syndrome profiles.
