Preliminary findings from an evaluation of the USDA Fresh Fruit and Vegetable Program in Wisconsin schools.
ABSTRACT In 2002, the US Department of Agriculture (USDA) created the Fresh Fruit and Vegetable Program (FFVP) to improve nutrition and help reduce the prevalence of childhood overweight and obesity. The FFVP provides funding for students from selected schools in each participating state to receive a free fresh fruit or vegetable snack daily for an academic year. In November 2005, Wisconsin was added to this program. In this study, we evaluate whether the Wisconsin FFVP resulted in positive changes in children's attitudes and behavior related to eating fruits and vegetables.
In 2006, 25 Wisconsin schools were selected by the Wisconsin Department of Public Instruction for FFVP participation. Study measures included a pre-test and post-test survey given to 4th, 7th, and 9th graders in the intervention and controls schools. Post-test data from all 25 intervention schools were not yet available for analysis. Our sample, therefore, consisted of 1127 participants: 784 students in 10 intervention schools and 343 students in 10 control schools. Independent samples t tests and multivariate probit regression analyses were used to examine attitudinal and behavioral program effects.
Compared to controls, intervention students reported an increased willingness to try new fruits (24.8% versus 12.8%, P<0.01) and vegetables (25.1% versus 18.4%, P=0.01) at school.
Findings indicate positive changes in attitudes and behavior among children participating in the Wisconsin FFVP.

ABSTRACT: OBJECTIVE: To systematically review evidence from field interventions on the effectiveness of monetary subsidies in promoting healthier food purchases and consumption. DESIGN: Keyword and reference searches were conducted in five electronic databases: Cochrane Library, EconLit, MEDLINE, PsycINFO and Web of Science. Studies were included based on the following criteria: (i) intervention: field experiments; (ii) population: adolescents 12-17 years old or adults 18 years and older; (iii) design: randomized controlled trials, cohort studies or pre-post studies; (iv) subsidy: price discounts or vouchers for healthier foods; (v) outcome: food purchases or consumption; (vi) period: 1990-2012; and (vii) language: English. Twenty-four articles on twenty distinct experiments were included with study quality assessed using predefined methodological criteria. SETTING: Interventions were conducted in seven countries: the USA (n 14), Canada (n 1), France (n 1), Germany (n 1), Netherlands (n 1), South Africa (n 1) and the UK (n 1). Subsidies applied to different types of foods such as fruits, vegetables and low-fat snacks sold in supermarkets, cafeterias, vending machines, farmers' markets or restaurants. SUBJECTS: Interventions enrolled various population subgroups such as school/university students, metropolitan transit workers and low-income women. RESULTS: All but one study found subsidies on healthier foods to significantly increase the purchase and consumption of promoted products. Study limitations include small and convenience samples, short intervention and follow-up duration, and lack of cost-effectiveness and overall diet assessment. CONCLUSIONS: Subsidizing healthier foods tends to be effective in modifying dietary behaviour. Future studies should examine its long-term effectiveness and cost-effectiveness at the population level and its impact on overall diet intake.Public Health Nutrition 11/2012; 16(07):1-14.

ABSTRACT: Objectives. We evaluated the effects of a Department of Education Fresh Fruit and Vegetable Program (FFVP) on food consumption habits in an inner-city, San Francisco high school. Methods. One intervention high school received a California state grant from the Department of Education to distribute fruit biweekly from fall 2008 to spring 2010 and coordinate associated nutrition education. Students completed 1793 surveys at the intervention school and 778 surveys at a comparison school that assessed fruit, vegetable, fast food and soda consumption habits. Pearson's chi-squared tests were used to compare consumption of foods. Results. At the end of the intervention period, the percentage of students consuming soft drinks once or more per day was significantly lower in the intervention versus comparison school (3.1% versus 8.9%, P = 0.01). Consumption of candy once or more per week was also lower in the intervention versus the comparison school in fall 2009 (55.7% versus 64.0%, P = 0.01). No significant changes in fruit and vegetable consumption were observed in the intervention or comparison schools. Conclusions. Fruit distribution programs in high schools may decrease high school students' consumption of soft drinks and candy.01/2012; 2012. DOI:10.5402/2012/252738

ABSTRACT: Overweight and obesity continue to be health concerns facing today's adolescent population. Along with metabolic and physical problems associated with obesity, today's obese adolescents also face many psychological issues such as high rates of depression, anxiety, and social discrimination. Obesity is commonly recognized as having many causes, such as genetic, lifestyle and environmental. There are four major modalities for management of overweight and obesity in adolescents: dietary management, increasing physical activity, pharmacological therapy, and bariatric surgery. The purpose of this study was to conduct a review of novel and emerging approaches for preventing and managing adolescent obesity. It was found that while not always the case, theory driven approaches are being better utilized in newer interventions especially by those directed toward prevention. New theories that are being used are the theories of reasoned action, planned behavior, intervention mapping, and social marketing. Schools are found to be the most common place for such interventions, which is appropriate since virtually all children attend some form of private or public school. Limitations found in many studies include the underuse of process evaluations, the low number of studies attempted, environmental or policy changes, and that not all studies used a similar control group for comparison.Adolescent Health, Medicine and Therapeutics 02/2010; 1:9-19.
