Predicting adolescents' intake of fruits and vegetables.

OBJECTIVE: To explore potential predictors of adolescents' fruit and vegetable intake by expanding on current theory and drawing from other adolescent research. DESIGN: This research reports on baseline and interim data from a school-based intervention study. Data were collected through surveys administered to students at the beginning and end of their 7th grade year. SETTING: The students attended 16 public schools in Minnesota. PARTICIPANTS: Data were collected on 3878 students; approximately half were female and 67% were white. All students in the 7th grade cohort were invited to participate in the surveys and over 94% completed both surveys. VARIABLES MEASURED: Our dependent variable, fruit and vegetable intake, was assessed by a validated fruit and vegetable food frequency scale. Predictive factors assessed included parenting style, spirituality/religiosity, depressive symptoms, and other commonly assessed predictors. ANALYSIS: Generalized linear mixed model regression. Omnibus test of association using P <.05 is reported. RESULTS: Subjective norms, barriers, knowledge, usual food choice, parenting style, spirituality/religiosity, and depressive symptoms were statistically significant predictors of intake. The model explained about 31% of the variance in fruit and vegetable consumption. CONCLUSIONS AND IMPLICATIONS: To better understand adolescents' fruit and vegetable intake, we must explore novel predictors. Our results need to be replicated, and more exploratory research in this field is needed.

Weight-related sports involvement in girls: who is at risk for disordered eating?

A 225-item questionnaire was completed by 5163 female 7th, 9th and 11th grade public school students in their classrooms to examine factors associated with eating disorders among girls involved in weight-related sports. Eating disorder symptoms were found in almost one third of girls involved in weight-related and non-weight-related sports. However, after controlling for grade, race, SES, and study design effect, girls in weight-related sports were 51% more likely to have eating disorder symptoms. Also, among girls in weight-related sports who had eating disorders, substance abuse, physical and sexual abuse history, depressive symptoms, suicide attempts, low family communication, and low parental caring were 98% to 377% more common.

A pricing strategy to promote sales of lower fat foods in high school cafeterias: acceptability and sensitivity analysis.

Prices of four low fat foods were reduced about 25% and prices of three high fat foods were increased about 10% to determine the impact on food purchases in a Midwestern suburban high school cafeteria to explore the impact of price on purchases. Low fat foods averaged about 13% of total sales. Sensitivity analysis was used to estimate that low fat foods would probably have averaged about 9% of total sales without the reduced price.

Nutrition labeling and value size pricing at fast-food restaurants: a consumer perspective.

PURPOSE: This pilot study examined nutrition-related attitudes that may affect food choices at fast-food restaurants, including consumer attitudes toward nutrition labeling of fast foods and elimination of value size pricing. METHODS: A convenience sample of 79 fast-food restaurant patrons aged 16 and above (78.5% white, 55% female, mean age 41.2 [17.1]) selected meals from fast-food restaurant menus that varied as to whether nutrition information was provided and value pricing included and completed a survey and interview on nutrition-related attitudes. RESULTS: Only 57.9% of participants rated nutrition as important when buying fast food. Almost two thirds (62%) supported a law requiring nutrition labeling on restaurant menus. One third (34%) supported a law requiring restaurants to offer lower prices on smaller instead of bigger-sized portions. CONCLUSION: This convenience sample of fast-food patrons supported nutrition labels on menus. More research is needed with larger samples on whether point-of-purchase nutrition labeling at fast-food restaurants raises perceived importance of nutrition when eating out.

Survey development for assessing correlates of young adolescents' eating.

OBJECTIVE: To describe the development and psychometric testing of a survey to assess multiple influences on young adolescents' eating behaviors. METHODS: A 204-item survey was piloted with middle-school students. We incorporated a broad view of determinants of eating behavior in an effort to expand the current field of predictors. RESULTS: The survey was reduced to 147 items and administered to 3,878 students. Internal consistencies were generally >0.70. Test-retest reliabilities were 0.30-0.98, mostly >0.60. CONCLUSIONS: We estimated psychometric properties for a range of measures in a diverse sample. This is important as the increasing demand for outcomes-based research expands the need for psychometrically sound survey measures.
