BACKGROUND: This study compared moderate-to-vigorous physical activity (MVPA) and sedentary behavior in U.S.-born and foreign-born adolescents and young adults, and differences in behavior change from adolescence to young adulthood by nativity. METHODS: Data on 2,039 U.S-born and 225 foreign-born participants from Project EAT-III (Eating and Activity in Teens and Young Adults) was used to examine MVPA, television/DVD/video viewing, and computer use. Participants completed surveys at baseline in Minneapolis/St. Paul, Minnesota secondary school classrooms in 1998-1999 (14.9±1.6 y) and follow-up measures online or by mail in 2008-2009 (25.3±1.6 y). RESULTS: At both time points, foreign-born participants reported significantly lower levels of MVPA than their U.S.-born counterparts (p<0.05). Foreign-born females at baseline and follow-up and foreign-born males at follow-up reported less television/DVD/video viewing compared with U.S.-born participants (p<0.01). All participants experienced a significant decline in MVPA from baseline to follow-up (p<0.001). Between-group analyses revealed a significantly greater decline in television/DVDs/video viewing for the foreign-born males compared with U.S.-born males from baseline to follow-up (mean change: foreign-born: -4.8 ± 1.32 hrs/wk, U.S.-born: -0.6 ± 0.6 hrs/wk; p<0.01). CONCLUSIONS: Differences in activity patterns between foreign-born and U.S.-born youth into young adulthood may contribute to disparities in chronic disease risk. Nativity, along with the social, environmental, and cultural context, should be considered when designing programs to promote MVPA and prevent obesity. HubMed – eating

Little research has been published concerning the differences between health oriented and ethically oriented vegetarians. The present study compared differences in conviction, nutrition knowledge, dietary restriction, and duration of adherence to vegetarianism between the two groups. Subjects completed an online survey and were grouped by original reason for becoming vegetarian (n=292, 58 health, 234 ethical), and current reason for remaining vegetarian (n=281, 49 health, 232 ethical). Whether grouped by current or original motivation, ethical vegetarians scored higher on the conviction instrument than health vegetarians and exhibited somewhat greater dietary restriction (significant when grouped by current motivation) and had been vegetarian for longer (significant when grouped by original motivation). Nutrition knowledge did not differ between the two groups. The results suggest that ethical vegetarians could experience stronger feelings of conviction and consume fewer animal products than health vegetarians, and may remain vegetarian longer. More research is necessary to understand how vegetarians’ eating behaviors are influenced by their motivational profiles.

Vegetables in the dark green group are the most nutritious, yet intake is low. Studies suggest that an increase in fruit and vegetables may improve diet-related health outcomes of African Americans. The aim of this exploratory study was to use the Reasoned Action Approach (RAA) to qualitatively assess salient, top-of-the-mind, beliefs (consequences, circumstances and referents) about eating and buying more dark green leafy vegetables each week over the next three months. Adult (n=30), Midwestern African-American women, who buy and prepare food for their household participated in a face-to-face salient belief elicitation. A content analysis of verbatim text and a descriptive analysis were conducted. Findings suggest that the RAA can be used to identify salient consequences, circumstances and referents about eating and buying more dark green leafy vegetables. The use of the RAA allowed for the extraction of specific beliefs that may aid in the development of nutrition education programs that consider the varying priorities, motivators and barriers that subgroups within the population have in regard to buying and consuming dark green leafy vegetables.
