ABSTRACT Consumption of fruits and vegetables is often recommended to promote healthy weight. The purpose of this study was to examine associations between fruit and vegetable intake and common weight management behaviors among US high school students who were trying to lose or stay the same weight.
Data from the 1999, 2001, and 2003 national high school Youth Risk Behavior Surveys were combined and the analyses stratified by gender (females, N = 16,709; males, N = 10,521). We considered 3 common weight management strategies--being physically active (ie, moderate activity for 30 minutes on 5 or more days per week or vigorous activity for 20 minutes on 3 or more days per week), eating a reduced calorie or fat diet, and limiting TV viewing. Sufficient fruit and vegetable intake was defined as eating 5 or more servings per day. Odds ratios (ORs) were calculated using logistic regression.
Only 21.3% of females and 24.7% of males ate sufficient fruits and vegetables. Being physically active was associated with sufficient fruit and vegetable intake. Eating a reduced calorie or fat diet and limiting TV viewing (among males) were associated with sufficient fruit and vegetable intake only among physically active students. The odds of sufficient fruit and vegetable intake were greatest among female (OR = 3.01) and male (OR = 2.91) students who combined all 3 strategies (31.5% of females, 21.6% of males).
Interventions that promote fruit and vegetable intake within the context of healthy weight management may be more effective if they combine nutrition and physical activity strategies. Further research is needed to test this approach.

    ABSTRACT: Purpose: This study was conducted to evaluate the effects of a brown rice and vegetable dietary program on the defecation conditions and health status of high school students. Method: A non-equivalent control group and pretest-posttest design was used. The subjects were 62 students (28 in the intervention group, 34 in the control group) who voluntarily participated in the study. The program was conducted from April 6, 2012 to July 3, 2012 at two high schools in Daegu city. During that time, two meals a day were supplied to the experimental group. Data on defecation condition and health status was collected using self-questionnaires. Results: After 12 weeks, students in the intervention group had a significantly better defecation condition than students in the control group. Students in the intervention group also had a significantly higher health status than students in the control group. Conclusion: The results suggest that a brown rice and vegetable dietary program improves the defecation condition and health status of high school students. Therefore, the development and study of nursing intervention and public health education program about brown rice as well as vegetable and fresh fruit consumption are necessary for these subjects.

    ABSTRACT: Purpose – Little is known about interrelationships among nutrition knowledge, attitude, dietary intake, and body satisfaction, which are important variables that play a role in nutrition education interventions. This paper aims to focus on these interrelationships. Design/methodology/approach – Students (n=279; 20.12±1.75SD years) enrolled at a large northeastern US university took an online survey. The survey contained a nutrition knowledge scale, attitude scale, food frequency scales, body areas satisfaction subscale, and demographic characteristics questions. To determine relationships, correlation coefficients were computed, along with forward stepwise regression to identify predictors of each study measure. Research limitations/implications – Data were collected from a non-probability sample in one geographical area at one time point. Findings – In males, significant positive correlations were found between fruit/vegetable servings and attitudes, knowledge, body satisfaction; and between knowledge and attitudes. Stepwise multiple regression analysis found fruit/vegetable servings and percent calories from fat significantly predicted attitudes, while in females attitude was a significant predictor variable for knowledge, fruit/vegetable servings, and percent of calories from fat. Among females, significant positive correlations occurred between attitudes and knowledge, and fruit/vegetable servings and attitudes. Practical implications – Nutrition and health interventions should incorporate lessons that work to improve one's attitudes toward nutrition. Interventions targeted to males should aim to increase nutrition knowledge, while interventions targeted to females should focus on nutrition knowledge and attitudes. Originality/value – This paper expands on what is known about young adults and key cognitive factors that influence their nutrition knowledge, attitudes, dietary intake, and body satisfaction. Nutrition educators can utilize the study findings to inform future nutrition interventions.

    ABSTRACT: Previous research has reported mixed results on the association between body weight measures (ie, perception of weight and weight loss goal) and cigarette smoking prevalence-and how these associations vary by sex and race. This longitudinal study assessed the relationship between these 2 body weight measures and smoking prevalence by smoking status (ie, nonsmoker, former smoker, smoker). Panel data of adolescents (N = 1592) from Louisiana schools completed survey interviews in the 9th grade and again in the 12th grade. Three separate ordinary least squares (OLS) regression analyses were conducted based on respondents' smoking status in the 9th grade: nonsmoker, former smoker, and smoker. The dependent variable, smoking prevalence was assessed in the 12th grade. Among nonsmokers, weight loss goal was associated with smoking in the 12th grade. Among former smokers, the association between weight loss goal and smoking varied by sex. Girls who reported the goal to lose weight smoked more than their male counterparts. In contrast, among those who did not have the goal of losing weight, boys smoked more than girls. Among adolescents who were already smokers in the 9th grade, weight loss goal was not significantly associated with smoking prevalence. Differences in the association between weight-related variables and smoking prevalence may be attributed, in part, to smoking status. School-based smoking interventions should target nonsmokers and female former smokers who desire weight loss.
