RESUMO

OBJECTIVES: Latinos are at a high risk of developing type 2 diabetes (T2D). Prediabetes is a major risk factor for T2D; however, progression to T2D can be slowed with engagement in healthy behaviors. Stress can hinder engagement with health behaviors. Qualitative methods were used to understand how Latinos with prediabetes attempted to modify their diet and physical activity behaviors to slow T2D progression and how stress affected their engagement in these behaviors. DESIGN: Semi-structured interviews were conducted with 20 Latinos with prediabetes in North Carolina. Participants were asked questions about types of stress they experienced and how stress affected their health. We generated codes on stress and stress responses and used content analysis to organize codes between and within participants. RESULTS: Behaviors changed after prediabetes diagnosis. Few participants reported changing their physical activity, however, all participants attempted to change their eating patterns by changing food types consumed and reducing portion sizes. The stress participants experienced impacted their ability to self-regulate their diet. They reported overeating or appetite suppression during stressful periods. Stress also affected cognitive responses by compromising healthy decision-making and instigating negative emotional reactions. Overall, stress complicated participants' ability to properly engage in recommended behaviors by negatively impacting participants' behavioral self-regulation and cognitive processes. CONCLUSIONS: Stress affects behavioral and cognitive progresses that adversely alters primarily dietary behaviors. Tailored plans acknowledging the impact of stress and providing coping and supportive help for dealing with stress may enhance engagement in healthy behaviors for Latinos with prediabetes.

RESUMO

To assess among college students their motivations for and perceived impacts of volunteering with Cooking Matters for Kids as part of No Kid Hungry NC. Seventeen college student volunteers responded to an online survey questionnaire assessing their motivations for volunteering and how they were impacted by their experiences. Motivational functions for volunteering (values, understanding, social, career, protective, enhancement) were assessed using the Volunteer Functions Inventory. The strongest motivational functions for volunteering were values and understanding. Students were also strongly motivated to volunteer related to the areas specifically addressed by the program (i.e., nutrition, public health, working with children). Perceived impacts of volunteering included being more comfortable working with children, improving knowledge/skills, gaining experience related to their future career, and having fun. Volunteering with Cooking Matters for Kids benefited college students. Issues addressed by the program and the desire to gain experience motivated students to volunteer.

RESUMO

OBJECTIVE: To examine whether bedtime is associated with usual sleep duration and eating behaviour among adolescents, emerging adults and young adults. DESIGN: Cross-sectional multivariable regression models, stratified by developmental stage, to examine: (1) association between bedtime and sleep duration and (2) associations between bedtime and specific eating behaviours at each developmental period, controlling for sleep duration. All models adjusted for sociodemographic characteristics, depressive symptoms and screen time behaviours. SETTING: National Longitudinal Study of Adolescent to Adult Health, waves I-IV, USA. PARTICIPANTS: A national probability sample surveyed in adolescence (aged 12-18 years, wave I: 1994-1995, n 13 048 and wave II: 1996, n 9438), emerging adulthood (aged 18-24 years, wave III: 2001-2002, n 9424) and young adulthood (aged 24-34 years, wave IV: 2008, n 10 410). RESULTS: Later bedtime was associated with shorter sleep duration in all developmental stages, such that a 1-h delay in bedtime was associated with 14-33 fewer minutes of sleep per night (Ps < 0·001). Later bedtime was also associated with lower odds of consuming healthier foods (i.e. fruits, vegetables; range of adjusted OR (AOR), 0·82-0·93, Ps < 0·05) and higher odds of consuming less healthy foods and beverages (i.e. soda, pizza, desserts and sweets; range of AOR, 1·07-1·09, Ps < 0·05). Later bedtime was also associated with more frequent fast-food consumption and higher sugar-sweetened beverage consumption (Ps < 0·05). CONCLUSIONS: Later bedtime was associated with shorter sleep duration and less healthy eating behaviours. Bedtime may be a novel behaviour to address in interventions aiming to improve sleep duration and dietary intake.

RESUMO

Research suggests that sleep duration and obesity are related, but the direction of this association remains uncertain. We applied autoregressive cross-lag models to evaluate the directionality of the relationship between sleep duration and BMI from adolescence through emerging and young adulthood, life stages where the risk for developing obesity are particularly high. Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we examined sex-stratified associations between sleep duration and BMI in this cohort from adolescence (ages 12-18, year 1996), to emerging adulthood (ages 18-24, 2001-2002), to young adulthood (ages 24-32, 2008), controlling for key confounders. For both males and females, higher BMI during an earlier developmental stage was associated with shorter sleep duration in the subsequent stage (both Bs = -0.02, ps < 0.01). However, sleep duration at an earlier developmental stage was not associated with BMI at the subsequent stage. Findings suggest that researchers should be cautious when interpreting cross-sectional relationships between sleep and BMI, as higher BMI may precede shorter sleep during adolescence to young adulthood. Researchers may also wish to account for potential bi-directional associations when modeling sleep and BMI using longitudinal data.

RESUMO

BACKGROUND: Mass media content may play an important role in policy change. However, the empirical relationship between media advocacy efforts and tobacco control policy success has rarely been studied. We examined the extent to which newspaper content characteristics (volume, slant, frame, source, use of evidence, and degree of localization) that have been identified as important in past descriptive studies were associated with policy progression over a 2-year period in the context of point-of-sale (POS) tobacco control. METHOD: We used regression analyses to test the relationships between newspaper content and policy progression from 2012 to 2014. The dependent variable was the level of implementation of state-level POS tobacco control policies at Time 2. Independent variables were newspaper article characteristics (volume, slant, frame, source, use of evidence, and degree of localization) and were collected via content analysis of the articles. State-level policy environment contextual variables were examined as confounders. RESULTS: Positive, significant bivariate relationships exist between characteristics of news content (e.g., high overall volume, public health source present, local quote and local angle present, and pro-tobacco control slant present) and Time 2 POS score. However, in a multivariate model controlling for other factors, significant relationships did not hold. DISCUSSION: Newspaper coverage can be a marker of POS policy progression. Whether media can influence policy implementation remains an important question. Future work should continue to tease out and confirm the unique characteristics of media content that are most associated with subsequent policy progression, in order to inform media advocacy efforts.

RESUMO

BACKGROUND: Tobacco control policies affecting the point of sale (POS) are an emerging intervention, yet POS-related news media content has not been studied. PURPOSE: We describe news coverage of POS tobacco control efforts and assess relationships between article characteristics, including policy domains, frames, sources, localisation and evidence present, and slant towards tobacco control efforts. METHODS: High circulation state (n=268) and national (n=5) newspapers comprised the sampling frame. We retrieved 917 relevant POS-focused articles in newspapers from 1 January 2007 to 31 December 2014. 5 raters screened and coded articles, 10% of articles were double coded, and mean inter-rater reliability (IRR) was 0.74. RESULTS: POS coverage emphasised tobacco retailer licensing (49.1% of articles) and the most common frame present was regulation (71.3%). Government officials (52.3%), followed by tobacco retailers (39.6%), were the most frequent sources. Half of articles (51.3%) had a mixed, neutral or antitobacco control slant. Articles presenting a health frame, a greater number of protobacco control sources, and statistical evidence were significantly more likely to also have a protobacco control slant. Articles presenting a political/rights or regulation frame, a greater number of antitobacco control sources, or government, tobacco industry, tobacco retailers, or tobacco users as sources were significantly less likely to also have a protobacco control slant. CONCLUSIONS: Stories that feature procontrol sources, research evidence and a health frame also tend to support tobacco control objectives. Future research should investigate how to use data, stories and localisation to encourage a protobacco control slant, and should test relationships between content characteristics and policy progression.

RESUMO

Excess weight gain tends to occur in young adulthood. However, research examining effective weight-related interventions for this age group has been limited. As one of seven trials in the EARLY Trials consortium (Early Adult Reduction of weight through LifestYle intervention), the CHOICES Study (Choosing Healthy Options in College Environments and Settings) tested effects of a technology-integrated, young adult weight gain prevention intervention. It was a randomized controlled trial with assessments at baseline (2011) and 4-, 12- and 24-months post-intervention initiation and included 441 participants (ages 18-35) who were students at three Minnesota community colleges. The 24-month intervention included a 1-credit academic course and social networking and support online intervention. This analysis examined effects on 12 secondary behavioral outcomes across three domains: diet (fast food, sugary beverages, breakfast, at-home meal preparation), physical activity/screen time (minutes and energy expenditure in leisure time physical activity, television viewing, leisure time computer use) and sleep (hours of sleep, time required to fall asleep, days not getting enough rest, difficulty staying awake). The intervention resulted in significant reductions in fast food (p=0.007) but increases in difficulty staying awake (p=0.015). There was limited evidence of other behavior changes at 4months (0.05

RESUMO

BACKGROUND/AIMS: Young adults are at risk of weight gain, but little is known about designing effective weight control trials for young adults or how to recruit and retain participants in these programs. The Choosing Healthy Options in College Environments and Settings (CHOICES) study evaluated the effectiveness of a weight gain prevention intervention for 2-year college students. We describe the methods used to recruit and retain the colleges and their students, describe the sample and discuss recommendations for future studies. METHODS: Students were recruited into a 24-month trial of a weight control intervention with assessment periods at baseline, 4-, 12- and 24-month follow-up. RESULTS: We successfully recruited 441 students through partnerships with three 2-year colleges through a variety of campus-based methods. Ultimately, 83.4% of the randomized cohort participated in the 24-month assessment period. Those retained more often were White (p = 0.03) compared to those who dropped out or were lost to follow-up; no other socio-demographic factor (e.g. gender, ethnicity and education), body mass index, body fat, waist circumference or weight status was observed to differ between randomly assigned groups. CONCLUSION: Two-year colleges and their students are interested in participating in weight-related trials and partnering with universities for research. Researchers must work closely with administrators to identify benefits to their institutions and to resolve student-level barriers to recruitment and retention. Our experiences from the Choosing Healthy Options in College Environments and Settings study should be useful in identifying effective recruitment and retention methods for weight gain prevention trials among young adults.

RESUMO

BACKGROUND: Obesity in young children remains a public health concern, and maternal weight is one of the strongest predictors of obesity in early childhood. However, parental adherence in interventions for young children is often low and existing programs have had mixed success. An innovative approach to treatment is needed that increases adherence among mothers and improves weight-related behaviors simultaneously in mothers and children. The objective of the Smart Moms randomized controlled trial (RCT) is to test the efficacy of a 6-month primarily smartphone-delivered program to reduce sugar-sweetened beverage and juice consumption among children ages 3-5 whose mothers are overweight or obese. This paper describes the study design and intervention. METHODS/DESIGN: Mother-child dyads were eligible if the mother was overweight or obese, owned a smartphone, and if the child was between the ages of 3-5 and consumed 12 oz or more per day of sugar-sweetened beverages (SSBs) and 100 % fruit juice. Participants were randomly assigned to the Smart Moms intervention or a waitlist control group. The intervention consisted of theoretically grounded and evidence-based behavioral strategies delivered through one group session, lessons on a mobile-optimized website, and text messages. Mothers submitted self-monitoring information via text message and received regular tailored feedback emails from interventionists. The primary outcome is change in child SSB and juice consumption and a secondary outcome is change in maternal weight. DISCUSSION: This Smart Moms study was designed to determine if a low-burden intervention delivered using mobile methods and targeted towards mothers could be effective at changing child sugar-sweetened beverage intake. Results will indicate if mobile-based methods can be a feasible way to engage mothers in family-based studies and will inform successful strategies to prevent childhood obesity through parent-targeted approaches. TRIAL REGISTRATION: Clinicaltrials.gov NCT02098902 (Registered March 25, 2014).

RESUMO

Our objective was to conduct a process evaluation of the CHOICES (Choosing Healthy Options in College Environments and Settings) study, a large, randomized, controlled trial designed to prevent unhealthy weight gain in young adults (aged 18-35) attending 2-year community colleges in the USA. The 24-month intervention consisted of participation in an academic course and a social networking and support website. Among intervention participants, completion rates for most course activities were >80%, reflecting a high level of dose received. Course retention and participant satisfaction were also high. Engagement results, however, were mixed with less than half of participants in the online and hybrid sections of the course reporting that they interacted with course materials ≥3 h/week, but 50-75% reporting that they completed required lessons 'all/very thoroughly'. Engagement in the website activities was also mixed with more than half of intervention participants logging onto the website during the first month, but then declining to 25-40% during the following 23 months of the intervention. Intervention engagement is a challenge of online interventions and a challenge of working with the young adult age group in general. Additional research is needed to explore strategies to support engagement among this population, particularly for relatively long intervention durations.

RESUMO

OBJECTIVE: (i) To examine associations between young adults' meal routines and practices (e.g. food preparation, meal skipping, eating on the run) and key dietary indicators (fruit/vegetable, fast-food and sugar-sweetened beverage intakes) and (ii) to develop indices of protective and risky meal practices most strongly associated with diet. DESIGN: Cross-sectional survey. SETTING: Minneapolis/St. Paul metropolitan area, Minnesota (USA). SUBJECTS: A diverse sample of community college and public university students (n 1013). RESULTS: Meal routines and practices most strongly associated with healthy dietary patterns were related to home food preparation (i.e. preparing meals at home, preparing meals with vegetables) and meal regularity (i.e. routine consumption of evening meals and breakfast). In contrast, factors most strongly associated with poor dietary patterns included eating on the run, using media while eating and purchasing foods/beverages on campus. A Protective Factors Index, summing selected protective meal routines and practices, was positively associated with fruit/vegetable consumption and negatively associated with fast-food and sugar-sweetened beverage consumption (P<0·001). A Risky Factors Index yielded significant, positive associations with fast-food and sugar-sweetened beverage consumption (P<0·001). The probability test for the association between the Risky Factors Index and fruit/vegetable intake was P=0·05. CONCLUSIONS: Meal routines and practices were significantly associated with young adults' dietary patterns, suggesting that ways in which individuals structure mealtimes and contextual characteristics of eating likely influence food choice. Thus, in addition to considering specific food choices, it also may be important to consider the context of mealtimes in developing dietary messaging and guidelines.

RESUMO

OBJECTIVE: To assess change in the 4-year prevalence (2006-2009) of the use of food in school fundraising and as rewards and incentives for students, following implementation of federal legislation in the USA in 2006. DESIGN: Serial cross-sectional design using trend analysis to assess school-level data collected over four consecutive years from 2006/2007 to 2009/2010. SETTING: Minneapolis/St. Paul, MN. SUBJECTS: Convenience sample of middle and high schools participating in two longitudinal, aetiological studies that examined youth, their environment and obesity-related factors. RESULTS: A significant and sustained decrease was demonstrated in the use of low-nutrient, energy-dense foods in school fundraising activities and the use of food and food coupons as rewards and incentives by teachers and school staff. CONCLUSIONS: Results support the utility of policy and legislative action as a tool for creating healthy, sustainable environmental change.

RESUMO

Understanding the contextual factors associated with why adults walk is important for those interested in increasing walking as a mode of transportation and leisure. This paper investigates the relationships between neighborhood-level sociodemographic context, individual level sociodemographic characteristics and walking for leisure and transport. Data from two community-based studies of adults (n=550) were used to determine the association between the area-sociodemographic environment (ASDE), calculated from U.S. Census variables, and individual-level SES as potential correlates of walking behavior. Descriptive statistics, mean comparisons and Pearson's correlations coefficients were used to assess bivariate relationships. Generalized estimating equations were used to model the relationship between ASDE, as quartiles, and walking behavior. Adjusted models suggest adults engage in more minutes of walking for transportation and less walking for leisure in the most disadvantaged compared to the least disadvantaged neighborhoods but adding individual level demographics and SES eliminated the significant results. However, when models were stratified for free or reduced cost lunch, of those with children who qualified for free or reduced lunch, those who lived in the wealthiest neighborhoods engaged in 10.7 minutes less of total walking per day compared to those living in the most challenged neighborhoods (p<0.001). Strategies to increase walking for transportation or leisure need to take account of individual level socioeconomic factors in addition to area-level measures.

RESUMO

Objective: The dissemination of effective obesity interventions requires the documentation of key elements of the intervention. But outcome papers and other published manuscripts often lack detail that allow the replication of the intervention. The Behavior Change Technique (BCT) Taxonomy (BCTTv1) is a widely used approach to identify key elements of an intervention study. This study compares the extent to which BCTs and domains identified in studies' intervention protocol are concordant with detail from corresponding intervention design and study outcome papers. Methods: Data come from four obesity interventions with complete intervention protocols as well as published intervention design and outcome papers. The number of domains and BCTs was calculated for each treatment arm and stratified by coding source. Emphasis of domains and BCTs was determined using an Analytical Hierarchy Process (AHP). Results: A review of each study's intervention protocol showed the mean number of domains and BCTs used in treatment arms as 11.8 and 26.7, respectively. Primary outcome papers had a mean loss of 34% of the reported domains and 43% of BCTS as compared with intervention protocl. Design papers showed a loss of 11% and 21% of domains and BCTs, respectively. Conclusions: The results confirm the limitations of using the BCTTv1 coding of outcome papers to describe obesity-related interventions. The results also highlight the need for mechanisms that allow for a full description of intervention content such as inclusion in a supplemental section of an online journal or the use of intervention-focused consort guidelines.

RESUMO

BACKGROUND: To examine how factors from a social ecologic model predict physical activity (PA) among adolescents using a longitudinal analysis. METHODS: Participants in this longitudinal study were adolescents (ages 10-16 at baseline) and one parent enrolled in the Transdisciplinary Research on Energetics and Cancer-Identifying Determinants of Eating and Activity (TREC-IDEA) and the Etiology of Childhood Obesity (ECHO). Both studies were designed to assess a socio-ecologic model of adolescent obesity risk. PA was collected using ActiGraph activity monitors at two time points 24 months apart. Other measures included objective height and weight, adolescent and parent questionnaires on multilevel psychological, behavioral and social determinants of PA, and a home PA equipment inventory. Analysis was conducted using SAS, including descriptive characteristics, bivariate and stepped multivariate mixed models, using baseline adjustment. Models were stratified by gender. RESULTS: There were 578 adolescents with complete data. Results suggest few statistically significant longitudinal associations with physical activity measured as minutes of MVPA or total counts from accelerometers. For boys, greater self-efficacy (B = 0.75, p = 0.01) and baseline MVPA (B = 0.55, p < 0.01) remained significantly associated with MVPA at follow-up. A similar pattern was observed for total counts. For girls, baseline MVPA (B = 0.58, p = 0.01) and barriers (B = -0.32, p = 0.05) significantly predicted MVPA at follow-up in the full model. The full multilevel model explained 30% of the variance in PA among boys and 24% among girls. CONCLUSIONS: PA change in adolescents is a complex issue that is not easily understood. Our findings suggest early PA habits are the most important predictor of PA levels in adolescence. Intervention may be necessary prior to middle school to maintain PA through adolescence.

RESUMO

Childhood obesity is one of the most pressing public health and medical problems in the United States. In the US, prevalence rates of childhood overweight and obesity have tripled in the past 30 years and the health implications and related medical costs of the disease are already evident. For the first time ever, weight-related Type 2 diabetes is being diagnosed in youth. Experts suggest that even if obesity prevalence remains static in the US, the lifetime risk of Type 2 diabetes for children born in 2000 is estimated at 30% for boys and 40% for girls (Narayan et al. J Am Med Assoc 290(14): 1884-1890, 2003). Annual hospital-related costs associated with treating obese children increased from 35 million dollars in 1979 to more than 127 million dollars in 1997-1999, based on 2001 dollars (Wang and Dietz Pediatrics 109(5): E81-E86, 2002). In addition to financial costs related to treating obesity, there are myriad social and personal costs of being an obese child and adult. This alarming rise in obesity rates among youth has been followed by initiatives by both the medical and public health communities to find appropriate and effective treatments as well as ways to prevent obesity. The following offers an overview of current trends and initiatives from both sectors and concludes with some thoughts on what the future may hold.

RESUMO

Both substance use and obesity are prevalent among youth. As youth age, substance use rates increase and over the past three decades, obesity rates among youth have tripled. While these two factors have both short- and long-term health impacts, little research has explored how substance use and obesity among youth may be related. This study explores the bi-directional longitudinal relationships between substance use and body composition. Participants (N = 704; 50.7% female) were mostly white (86.4%) with a baseline mean age of 14.7 years. Objectively measured body composition was used to calculate body mass index z-scores (BMI z-score) and percent body fat. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between body composition and self-reported substance use (alcohol, cigarette, and marijuana), adjusting for socio-demographic characteristics, pubertal status, and weight satisfaction. Baseline alcohol use predicted decreased BMI z-score at follow-up and a similar association with percent body fat approached significance. Baseline cigarette use predicted increased percent body fat. No longitudinal associations were seen between baseline body composition and future substance use. Our results suggest that substance use contributes to subsequent body composition; however, body composition does not contribute to subsequent substance use. Continued research that explores these relationships longitudinally is greatly needed.

RESUMO

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4 %) youth, 51 % female, with a baseline mean age of 14.7 years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.

RESUMO

OBJECTIVE: To assess changes in self-efficacy and attitudes related to healthy eating and cooking in Cooking Matters for Kids participants. DESIGN: Prepost study design. SETTING: Cooking Matters for Kids programs offered by 35 organizations. PARTICIPANTS: Predominantly third- to fifth-grade children participating in Cooking Matters for Kids lessons during fiscal years 2012-17 with matched presurvey and postsurveys (n = 18,113). INTERVENTION(S): Cooking Matters for Kids consists of six 2-hour experiential nutrition and cooking education lessons. MAIN OUTCOME MEASURE(S): Self-efficacy related to healthy eating and cooking and attitudes toward healthy foods assessed through the Cooking Matters for Kids Participant Survey. ANALYSIS: Changes from the presurvey to postsurvey were assessed using mixed models and repeated measures ordered logistic regression accounting for clustering by course. Effect sizes were calculated using Cohen d for repeated measures. A Bonferroni adjustment was used to correct for multiple comparisons (α = 0.025). RESULTS: Both overall and individual self-efficacy and attitude scores improved from presurvey to postsurvey (P < 0.0001). The effect sizes were 0.35 for overall self-efficacy score and 0.17 for overall attitude score. CONCLUSIONS AND IMPLICATIONS: Participation in Cooking Matters for Kids was associated with improvements in self-efficacy and attitudes related to healthy eating and cooking.

RESUMO

Observational studies of breakfast frequency in children and adults suggest an inverse (protective) association between the frequency of eating breakfast and the risk for obesity and chronic diseases such as type 2 diabetes. More prospective studies with stronger designs are needed, as are experimental studies on this topic. In addition, above and beyond breakfast frequency, the roles of dietary quality and composition need to be studied in the context of eating or skipping breakfast. Experimental studies are also necessary to rigorously test causality and biological mechanisms. Therefore, we conducted 2 pilot experimental studies to examine some of the effects of breakfast skipping and breakfast composition on blood glucose and appetite in children and adults. Our results suggest that breakfast frequency and quality may be related in causal ways to appetite controls and blood sugar control, supporting the hypothesis that the breakfast meal and its quality may have important causal implications for the risk of obesity and type 2 diabetes.
