BACKGROUND: Although parenthood is a common life event in early adulthood, little is known about whether parenthood is associated with weight and weight-related health behaviors, including dietary intake and physical activity. OBJECTIVE: In this article we examine whether parents of young children (aged </=5 years) report different dietary intake, physical activity, and BMIs compared with young adults without children. METHODS: Data for this analysis were drawn from the second and third waves of Project EAT (Eating and Activity in Teens and Young Adults), a longitudinal population-based cohort study. Young adults (838 women, 682 men) from diverse ethnic and socioeconomic backgrounds were included. Gender-stratified linear regression models were used to examine associations between parental status and dietary intake, hours of physical activity, and BMI. Results were adjusted for each health behavior outcome level 5 years earlier (time 2). RESULTS: Results indicate that although many dietary behaviors were the same between parents and nonparents, mothers reported greater consumption of sugar-sweetened beverages, total energy, and percent saturated fat compared with women without children. Both mothers and fathers had lower amounts of physical activity compared with nonparents. Mothers had higher mean BMIs than women without children. No difference was observed in BMIs between fathers and men without children. CONCLUSIONS: Our findings suggest that pediatricians and health care providers may want to consider discussing dietary intake and physical activity with new parents to identify ways to engage in healthful behaviors given the daily demands of parenthood, both to improve parents' own health and to help them model healthful behavior for their children.

Sport is a promising setting for obesity prevention among youth, but little is known about whether it prevents obesity. We reviewed research comparing sport participants with nonparticipants on weight status, physical activity, and diet. Among 19 studies, we found no clear pattern of association between body weight and sport participation. Among 17 studies, we found that sport participants are more physically active than those who do not participate. We found seven studies that compared the diet of sport participants with non-participants. These studies reported that youth involved in sport were more likely to consume fruits, vegetables, and milk, and also more likely to eat fast food and drink sugar-sweetened beverages and consume more calories overall. It is unclear from these results whether sports programs, as currently offered, protect youth from becoming overweight or obese. Additional research may foster understanding about how sport, and youth sport settings, can help promote energy balance and healthy body weight.

There is a paucity of research regarding the contextual factors that influence health behaviors to inform the development of programs and services for youth during the transition from adolescence to young adulthood. Researchers are thus in need of efficient strategies for surveying diverse populations of young adults. This study among a population-based sample of young adults aimed to 1) examine response to a mixed-mode survey design (web and mailed surveys) and 2) identify demographic correlates of response mode. Young adults who participated in previous study waves were invited to participate in the third wave of a 10-year longitudinal study (Project EAT-III: 2008-2009) examining factors associated with weight-related behaviors. Participants were mailed invitation letters providing the web address and a unique password for completing the survey. Nonresponders were mailed three reminder invitations; the third mailing included the paper form, and all other mailings included a postage-paid card for requesting the paper form. Most completed surveys (82.1% of n=2,287) were returned by respondents within the first four months of fielding prior to the mailing which included the paper form. Nearly all of these early responders (92.6% of n=1,878) and 86.5% of the full respondent sample (n=1,979 of 2,287) completed the web form. Response to the web versus mailed paper form of the survey was associated with age >25 years, higher socioeconomic status, current employment, student status, and having no children. The combination of web and mailed survey modes is an effective strategy for conducting data collection in demographically diverse, young adult populations.

OBJECTIVE To examine associations between watching television during family meals and dietary intake among adolescents. DESIGN Cross-sectional study using survey data from a diverse sample of adolescents. SETTING Data were collected from a school-based survey during the 1998-1999 school year. PARTICIPANTS Middle and high school students (N = 4746) from 31 public schools in the Minneapolis-St. Paul area. Response rate was 81.5%. VARIABLES MEASURED Intake of fruits, total vegetables, dark green/yellow vegetables, calcium-rich food, grains, soft drinks, fried food, snack food, calories, family meal frequency, and watching television during meals. ANALYSIS General linear modeling comparing dietary intake across 3 groups. RESULTS 33.5% of boys and 30.9% of girls reported watching television during family meals. Adolescents watching television were found to have lower intakes of vegetables, dark green/yellow vegetables, calcium-rich food, and grains and higher intakes of soft drinks compared to adolescents not watching television during meals. However, watching television during family meals was associated with a more healthful diet than not eating regular family meals. CONCLUSIONS AND IMPLICATIONS Watching television during family meals was associated with poorer dietary quality among adolescents. Health care providers should work with families and adolescents to promote family meals, emphasizing turning the TV off at meals.

OBJECTIVE Little is known about the food and weight-related behaviors of Hmong adolescents. This study assessed these behaviors in Hmong adolescents and determined if they differed between Hmong and white teens or by country of birth. DESIGN School-based cross-sectional study. SUBJECTS/SETTING Hmong (n=649) and white (n=2,260) adolescents from 31 public middle and high schools in the Minneapolis/St Paul, MN, metropolitan area who participated in Project EAT (Eating Among Teens). MAIN OUTCOME MEASURES Family meals, grocery shopping, and meal preparation; consumption of breakfast, snacks, and fast foods, physical activity and inactivity; body satisfaction, weight concern, body mass index, and weight-control behaviors. STATISTICAL ANALYSES PERFORMED Variables were compared across race/ethnicity and by country of birth using χ2 tests and general linear model regression. RESULTS Hmong students reported greater participation in family meals and more involvement with food purchasing and preparation. Fast-food consumption was similar among groups. Hmong teens reported less frequent breakfast consumption. The prevalence of overweight was higher in Hmong male adolescents than white male adolescents, but similar among female adolescents. Hmong students reported higher levels of weight concern, body dissatisfaction, dieting, unhealthful weight-control behaviors, less physical activity, and more inactivity than white students. Hmong male adolescents participated in extreme unhealthful weight-control behaviors four times more often than white male adolescents. CONCLUSIONS Hmong adolescents appear to be at increased risk for obesity, body dissatisfaction, and unhealthful weight-control behaviors compared to white adolescents. There is a need for culturally tailored interventions to address these nutrition and weight issues among Hmong adolescents.

OBJECTIVE To evaluate the long-term impact of adolescent dating violence (ADV) on behavioral and psychological health. STUDY DESIGN From a diverse sample of older adolescents who completed Project EAT in 1999 (wave 1) and 2004 (wave 2; mean age 20.4), 23 male and 102 female adolescents reporting ADV were compared with 671 male and 720 female adolescents reporting no ADV. RESULTS ADV was positively associated with cigarette smoking and suicide attempts for both sexes, binge-eating and suicidal ideation in male adolescents, and smoking marijuana and high depressive symptoms in female adolescents in analyses unadjusted for wave 1 outcomes. In analyses adjusted for wave 1, in female adolescents, ADV was significantly associated with smoking cigarettes, marijuana use, and high depressive symptoms and marginally associated with suicide attempts; in male adolescents, ADV was significantly associated with smoking cigarettes and marginally associated with binge-eating and suicidal ideation. ADV was significantly associated with an overall high-risk profile (presence > or = 3 health outcomes) for both sexes; results remained significant in female adolescents after adjusting for wave 1. CONCLUSIONS ADV is associated with greater likelihood of problematic health factors and increases nonspecific risk toward behavioral and psychological impairment in youth, particularly female adolescents.

OBJECTIVE To determine whether adolescents who participate in a weight-related sport are at increased risk for unhealthful weight-control behaviors and steroid use. DESIGN This was a population-based study (Project EAT [Eating Among Teens]). SUBJECTS/SETTING Subjects were 4,746 adolescents (50.2% males, 49.8% females) from 31 public middle and high schools in the Minneapolis/St Paul area of Minnesota. STATISTICAL ANALYSIS PERFORMED Descriptive statistics, χ2 analyses, and multiple logistic regression were used. Data were adjusted for sociodemographic variables and body mass index. MAIN OUTCOME VARIABLES Unhealthful weight-control behaviors and steroid use. RESULTS More males (20.4%) than females (16.2%) reported participation in a weight-related sport. Males who reported participation in a weight-related sport had an increased risk of past-week vomiting (odds ratio [OR]=5.7), laxative use (OR=6.8), as well as past-year vomiting (OR=4.9), laxative use (OR=3.4), diuretic use (OR=6.0), and steroid use (OR=3.7), compared with those males who did not report participation. Females who reported participation in a weight-related sport had an increased risk of past week vomiting (OR=2.1), as well as past year vomiting (OR=2.0), laxative use (OR=2.6), and steroid use (OR=2.6), compared with those who did not report participation in a weight-related sport. CONCLUSIONS The current study shows that participation in a sport that adolescents perceive as emphasizing weight is strongly associated with unhealthful weight-control behaviors and steroid use. Preventive efforts, targeting parents, coaches, and adolescents are needed to decrease this risk.

Manual and oculomotor measures of sequence learning were examined on the serial reaction time (SRT) task Participants were assigned into four groups differing on response modality (manual, oculomotor) and trial type (sequence, pseudorandom). The pattern of manual RTs replicated previous studies. Frequency of anticipatory eye movements followed similar patterns as RTs. Participants made many anticipations, even in pseudorandom blocks, and frequency of anticipations did not depend on presence of concurrent manual responses. Excluding participants with explicit awareness did not change results. Anticipations were negatively related to RTs in both incidental and intentional learning. Anticipations were positively related to sequence recall in intentional, but not incidental, learning. Results suggest that (1) anticipatory eye movements reflected sequence learning and (2) participants made overt and covert shifts of visuospatial attention to likely stimulus locations prior to stimulus onset, whether or not they made manual responses and whether or not there was a sequence.

This research examined whether body dissatisfaction prospectively predicted depressive mood and low self-esteem in adolescent girls and boys 5 years later. Participants were early-adolescent girls (n = 440, Time 1 M age = 12.7 years) and boys (n = 366, Time 1 M age = 12.8 years) and midadolescent girls (n = 946, Time 1 M age = 15.8 years) and boys (n = 764, Time 1 M age = 15.9 years). After controlling for Time 1 of the relevant dependent variable, ethnicity, socioeconomic status, and body mass index, Time 1 body dissatisfaction was a unique predictor of Time 2 depressive mood and low self-esteem in early-adolescent girls (depressive mood: F = 4.80, p < .05; self-esteem: F = 9.64, p < .01) and midadolescent boys (depressive mood: F = 12.27, p < .001; self-esteem: F = 9.38, p < .01) but not in early-adolescent boys or midadolescent girls. These findings are consistent with the hypothesis that body dissatisfaction is a risk factor for depressive mood and low self-esteem in both girls and boys but in differe...
