Objective: To evaluate the short-term outcome of the social marketing approach used in Project FIT, we developed a school- and community-based programme for promoting healthful eating and physical activity in kindergarten to 5th-grade children and their parents. Design: A 2-year quasi-experiment for children and two cross-sectional surveys for parents. Setting: We included low-income, urban and ethnically diverse elementary schools and neighbourhoods in Grand Rapids, Michigan, USA. Method: Students in 3rd, 4th and 5th grades were surveyed in four intervention schools (four time points, N with at least one time point measurement = 664) and two control schools (N = 195). Parents of intervention students were surveyed at baseline (N = 286) and follow-up (N = 215). Key dependent variables included self-reported healthful eating and physical activity. Key independent variables included awareness, knowledge, motivation and attitudes towards Project FIT. Analysis: We analysed generalised linear mixed models and generalised estimation equation (GEE) models for the student surveys and mean difference tests and logistic regressions for the parent surveys. Results: The proportion of students who were aware of Project FIT increased over time. GEE models showed that selected key dependent variables were significantly associated with self-reported healthful eating and physical activity. Parents were more aware of Project FIT at follow-up compared to the baseline survey, and their attitudes were significantly associated with increased healthful eating (vegetables, fruits and whole grains). Conclusion: The social marketing approach utilised in Project FIT contributed to increasing awareness and achieving behavioural goals of healthful eating and physical activity.

Purpose: The objective of this study was to examine the independent and combined association of physical activity and body mass index (BMI) with blood pressure in youth. Methods: Youth aged 8-18 years from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) with BMI, blood pressure, and physical activity (accelerometer) were included in the analyses. A total of 2585 subjects (1303 males; 47% of all 8- to 18-year-olds) met these criteria. Results: Obese youth had a systolic blood pressure that was 8 mm Hg higher than normal weight youth. A significant interaction between BMI and physical activity on blood pressure was found (P < .001), and group differences among the BMI/activity groups showed that the 3 obese groups and the overweight/least active group had significantly higher systolic blood pressure than the normal weight/active group across all analyses. The overweight/least active and normal weight/least active groups had significantly higher diastolic blood pressure than the normal weight/active group as well. Conclusions: This study showed a significant independent and combined association of BMI and physical activity with blood pressure in youth. Interventions need to focus on the reduction of fatness/BMI as a way to reduce the cardiovascular risk in youth. [ABSTRACT FROM AUTHOR]

Objective Assess physical activity (PA) and nutrition recommendation knowledge in college students. Participants: 71 students (n = 41 females;18 to 22 years) measured in May of 2014. METHODS: Knowledge of existence and accuracy of PA and nutrition recommendations were assessed via a verbal survey. Results: Most (67.6%) were aware PA recommendations exist, but only 26.8% could accurately report them. Almost all (91.5%) were aware nutrition guidelines exist, but no higher than 23.9% answered any specific recommendation correctly. There were no significant associations between sex or body mass index (BMI) and either awareness or accuracy of PA or nutrition recommendations. Non-Kinesiology majors were 3.3 times more likely to answer that they were not aware of the existence of PA recommendations, compared to Kinesiology majors. Conclusions: Accurate knowledge of the PA and nutrition recommendations are very low and given that the majority of participants were categorized as overweight or obese, teaching these guidelines needs to be the priority.
