Linking Primary Care, Communities and Families to Prevent Obesity Among Preschool Children (Net-WORKS)
Net-WORKS is a 7-year study that aims to prevent obesity among low-income, preschool children through linking primary care, parent community education, and community-based food and physical activity resources. Five hundred (500) families with preschool-aged children will participate in the randomized study. The study will include a family advocate who will work with each family to make changes in the home environment related to healthy food choices, reducing screen time, and increasing physical activity.

Food, Attitudes and Body (FAB) Study
Previous studies have suggested that commercial weight-loss programs can promote modest, but clinically significant, weight loss. One such program, Jenny Craig, incorporates several specific features that have independently been shown to be useful in promoting weight loss including individualized counseling, a low-calorie diet, prepackaged foods, and increased physical activity. Nancy Sherwood, PhD, University of Minnesota, through a subcontract to the University of California-San Diego, conducted a 3-year multicenter, randomized, clinical research trial funded by Jenny Craig, Inc. The “Food, Attitudes, and Body” study examined whether this particular commercial program was effective in helping people to lose weight and maintain that weight loss for two years.

A goal of this project, if successful, was to provide a dietary alternative to pharmacological approaches to reduction in body fat. Outcomes further established the effectiveness of viscous polysaccharides on adiposity, as well as expanding our knowledge of the relationship between adiposity, inflammation, and adipokine secretion.
