A quantitative survey measure of moral evaluations of patient substance misuse among health professionals in California, urban France, and urban China.

BACKGROUND: The merits and drawbacks of moral relevance models of addiction have predominantly been discussed theoretically, without empirical evidence of these potential effects. This study develops and evaluates a novel survey measure for assessing moral evaluations of patient substance misuse (ME-PSM). METHODS: This measure was tested on 524 health professionals (i.e., physicians, nurses, and other health professionals) in California (n = 173), urban France (n = 102), and urban China (n = 249). Demographic factors associated with ME-PSM were investigated using analyses of variance (ANOVAs) and t-tests, with results suggesting that ME-PSM is higher among younger health professionals, nurses (when compared with physicians and other health professionals), and Chinese health professionals (when compared with French and American health professionals). RESULTS: Results provide preliminary support for the psychometric quality of the survey measure introduced in this study, including the existence of a single latent structure and partial invariance of collected data across countries. CONCLUSION: The survey measure for ME-PSM which was developed and tested in the current study appears to hold potential utility for use as a measure of moral views of patient substance misuse. With development, this measure may be used to examine moral evaluations, both as factors of stigma and of other clinical factors associated with the treatment of patients with substance use disorders.

Negative emodiversity is associated with emotional eating in adolescents: An examination of emotion dynamics in daily life.

INTRODUCTION: Emotional eating is a mental health concern, common in adolescents, that develops as a result of their tendency to use high-energy food to regulate their fluctuating emotions. Due to their highly fluctuating emotional life, adolescents tend to have unique within-person profiles of emotional experiences that change across moments and days, often lost in global assessments of emotions. Hence, it is imperative to examine individual differences in dynamics of emotions, as experienced in daily life, in relation to emotional eating in adolescents. METHODS: In an Ecological Momentary Assessment study, we examined individual differences in three within-person dynamic characteristics (baseline levels, intraindividual variability, and emodiversity) of emotions in 158 dominantly Hispanic adolescents in the United States, aged 14-17 years old, predicting trait-level emotional eating. RESULTS: Results indicated that higher negative emodiversity, baselines, and variability in stress were predictive of emotional eating in adolescents. When all considered together, negative emodiversity (i.e., variety of the types of negative emotions experienced in one's daily life) remained the only significant predictor of emotional eating. CONCLUSIONS: This study affirms the importance of diversity in emotional experiences in relation to emotional eating, particularly in daily contexts of adolescents' lives. Additionally, the study emphasizes the importance of distinguishing between diversity (i.e., variety in types) in positive versus negative emotional experiences with regard to emotional eating. By taking into account the ecological validity of adolescents' daily lives and individual differences in dynamical changes in emotions, we are taking a step forward by shedding light on how the dynamics of negative emotions-in terms of within-person baselines, variability, and diversity-might be related to general levels of emotional eating in adolescents.

Exploring mediation pathways on the relationship between acculturation and binge eating among Latino adolescents.

The objective of this study was to explore the mediating effects of emotional eating, restrained eating, and external eating on the relationship between acculturation and binge eating among Latino adolescents. Adolescents who self-identified as Latino (N = 285) at public high schools in Southern California were recruited and completed a self-report survey. Acculturation was assessed using the 8-item Acculturation, Habits, Interests for Multicultural Adolescents (AHIMSA) scale for adolescents, mediators were assessed using Dutch Eating Behavior Questionnaire (DEBQ), and binge eating was assessed using a 13-item Eating Disorder Diagnostic Scale. A bootstrapped multiple mediation model was used to test mediation pathways. Findings suggest that individually each eating style-emotional, restrained and external eating pathway did not reach significance singly, but that jointly, their combined effect was significant with a total indirect effect (B = 0.15, CI 0.01-0.30) indicating an additive effect of the three eating styles. Future research should examine additional mediators of the relationship between acculturation and binge eating.

Exploring Potential Mediation Pathways on the Relationship Between Acculturation and Body Mass Index (BMI) Among Latino Adolescents.

BACKGROUND: Positive associations have been observed between acculturation and body mass index (BMI), but the mediators of this relationship are not well established. Acculturation researchers have called for investigating the influence of socio-contextual variables as mediators. The objective of this study was to test the mediating effects of salty snacks, sweet snacks, physical activity, and sedentary behavior on the relationship between acculturation and BMI among Latino adolescents. METHODS: Adolescents who self-identified as Latino (n = 431) at public high schools in Southern California were recruited and completed a self-report survey. A bootstrapped multiple mediation model was used to test mediation pathways. RESULTS: Acculturation was positively associated with physical activity (B = 0.09, p < .05). The indirect effects of salty snacks, sweet snacks, physical activity, and sedentary behavior were not associated with BMI, suggesting no mediation. CONCLUSIONS: Future research should examine additional mediating variables on the relationship between acculturation and BMI.

Loneliness and cravings for sugar-sweetened beverages among adolescents.

PURPOSE: The consumption of sugar-sweetened beverages (SSBs) is associated with weight gain in both children and adults. In addition to environmental factors, such as food availability, psychological variables, including mood states, also impact intake. In the current study, we focus on momentary associations between feelings of loneliness and craving for SSBs among adolescents and explore the moderating role of family functioning. Loneliness has been associated with a wide range of health outcomes, but to date, few studies have examined its association with cravings for SSBs. METHODS: Using an ecological-momentary assessment design, data were collected on 158 (males = 68, mean age = 15.13 ± 2.27 years) participants. Multilevel mixed-effects models were used to examine the relations between the main and interactive effects of loneliness and family functioning on cravings for SSBs, independent of other negative emotions. RESULTS: Results suggest that loneliness in adolescents was associated with a small increase in craving for SSBs. Importantly, the relationship held after controlling for negative emotions, suggesting the unique role of loneliness. However, positive family functioning did not mitigate the relations between loneliness and craving for SSBs. CONCLUSIONS: Loneliness uniquely contributes to cravings for SSBs. At the same time, family functioning did not buffer the influence of loneliness on cravings for SSBs among adolescents.

An Examination of Family Variables as Mediators of the Association of Acculturation With Sugar-Sweetened Beverage Consumption Among Latinx Adolescents.

The objective of this study was to examine the mediating effects of family support for dietary habits and family meal frequency on the relationship between acculturation and sugar-sweetened beverage (SSB) consumption among Latinx adolescents (N = 131). Acculturation was positively associated with SSB consumption (B = 0.07, P < .01). Results suggest that family support for dietary habits and family meal frequency did not mediate the relationship between acculturation and SSB consumption. However, acculturation was negatively associated with family support for dietary habits (B = -0.10, P < .01) and family meal frequency (B = -0.11, P < .05). Future research should examine other family influences as mediators of the relationship between acculturation and SSB consumption.

The Association of Trail Features With Self-Report Trail Use by Neighborhood Residents.

BACKGROUND: Urban trails are a useful resource to promote physical activity. This study identified features of urban trails that correlated with trail use. METHODS: Multiuse urban trails were selected in Chicago, Dallas, and Los Angeles. An audit of each trail was completed using the Systematic Pedestrian and Cyclist Environmental Scan for Trails instrument, identifying built environmental features. A self-report of trail use was obtained from trailside residents (N = 331) living within 1 mile of each trail. Univariate and multivariate Poisson regressions controlled for trail time from home and motivation for physical activity. RESULTS: Positive associations with the past month's hours on the trail were observed for the presence of distance signs, vegetation height, vegetation maintenance, and trail crowding, and a negative association was observed for the presence of crossings on the trail. Positive associations with dichotomous trail use were observed for the presence of distance signs, vegetation height, and vegetation maintenance, and a negative association was observed for the presence of crossings on the trail. CONCLUSIONS: These correlates should be confirmed in other studies and, if supported, should be considered in the promotion and design of urban trails.

Randomized controlled trial evaluating an intervention supporting implementation of sun safety policies in California public elementary schools.

Solar ultraviolet radiation (UV) exposure is the primary risk factor for skin cancer and children receive about one-quarter of lifetime UV exposure before age 18. Thus, skin cancer prevention is essential for children. The objective of this study was to test an intervention to facilitate implementation of district sun safety policies. Elementary schools (N = 118) from 40 California public school districts with a school board-approved policy for sun safety were recruited along with one principal and teacher from each school. Elementary schools were randomly assigned to receive the 20-month Sun Safe Schools intervention (N = 58) or to a minimal informational control condition (N = 60). Principals were 47.8 and teachers 44.3 years of age and were predominately female (principals 72.7%; teachers 86.7%) and White (principals 72.0%; teachers 68.2%). The 20-month Sun Safe Schools intervention was delivered to principals and included a coaching session, telephone and email contacts, provision of resources for practice implementation, and a small grant program. The principal (N = 118) and a teacher (N = 113) at each school reported on school sun protection practices 20-months post-baseline. The schools were diverse in student characteristics (M = 64.1% free/reduced price meals; M = 54.5% Hispanic). Intervention principals reported implementing more sun safety practices overall (control M = 2.7, intervention M = 4.2, p < .005) and more practices not present in the district's policy (control M = 0.4, intervention M = 0.9, p = .005). Principals and teachers combined replicated these findings and also reported implementing more practices present in the district policy (control M = 0.9, intervention M = 1.3, p = .005). In sum, the intervention increased sun safety practices in public elementary schools. Trial Registration. This study is registered in ClinicalTrials.gov, www.clinicaltrials.gov, with the identification number of NCT03243929.

Parent reports of sun safety communication and behaviour for students in a randomised trial on a school policy implementation intervention.

OBJECTIVE: Schools are an important setting for skin cancer prevention. An intervention for implementation of school sun safety policy, Sun Safety Schools (SSS), was evaluated. METHODS: Primary schools (n=118) in California school districts that had already adopted a sun safety policy were enrolled in a study with a randomised controlled design. Half of the schools were randomised to SSS intervention (N=58). Parents completed an online post-test. RESULTS: More parents in intervention schools received information about sun safety (mean=26.3%, sd=3.1%, p=0.017) and children more frequently wore sun-protective clothing when not at school (mean=2.93, sd=0.03, p=0.033) than in control schools (mean=18.0%, sd=2.5%; mean=2.83, sd=0.03, respectively). In schools where principals reported implementing sun safety practices, parents reported that children spent less time outdoors at midday (mean=14.78 hours, sd=0.25, p=0.033) and fewer were sunburned (mean=12.7%, sd=1.1%, p=0.009) than in non-implementing schools (M=16.3 hours, sd=0.67; mean=21.2%, sd=3.8%, respectively). Parents who received sun safety information (mean=3.08, sd=0.04, p=0.008) reported more child sun protection than parents not receiving information (mean=2.96, sd=0.02). CONCLUSIONS: A school district sun protection policy and support for implementation increased dissemination of sun safety information to parents and student sun safety. Implications for public health: Technical assistance for sun safety policies may increase sun protection of children.

School-Level Factors Associated with Sun Protection Practices in California Elementary Schools.

BACKGROUND: This study examined implementation of district sun safety policy in schools and tested correlates of implementation in California public school districts. METHODS: Principals (N = 118) and teachers (N = 113) in California public elementary schools (N = 118) were recruited and completed a survey on sun protection policies and practices. The sample contained schools whose districts subscribed to the California School Boards Association and adopted Board Policy 5141.7 for sun safety. Principals and teachers reported on implementation of 10 school practices related to BP 5141.7 indicating which practices were implemented in the school. RESULTS: Years in public education (Exponentiated Score (ES) = 0.51, p < .001), years worked in the current district (ES = 0.49, p < .001), perception that parents should take action to protect children from the sun (ES = 0.43, p < .01), and personal skin phenotype (Low Risk ES = 0.55; High Risk ES = 0.09, p < .05) were associated with number of practices implemented in the school using multiple Poisson regression. CONCLUSIONS: Policy implementation is more likely among schools with experienced faculty, when parents are seen as important partners in student skin cancer prevention, and when school principals and teachers have a lower personal risk phenotype.

Economic Evaluation of a Sun Protection Promotion Program in California Elementary Schools.

BACKGROUND: An economic evaluation of Sun Safe Schools intervention designed to aid California elementary schools with implementing sun safety practices consistent with local board-approved policy. DESIGN: Program cost analysis: intervention delivery and practice implementation. SETTING: California elementary schools (58 interventions and 60 controls). Principals at 52 intervention and 53 control schools provided complete implementation data. PARTICIPANTS: Principals completing pre-/postintervention surveys assessing practice implementation. INTERVENTION: Phone-based 45-minute session with a project coach on practice implementation, follow-up e-mails/phone contacts, $500 mini-grant. Schools chose from a list of 10 practices for implementation: ultraviolet monitoring, clothing, hats, and/or sunscreen recommendations, outdoor shade, class education, staff training and/or modeling, parent outreach, and resource allocation. The duration of intervention was 20 months. Rolling recruitment/intervention: February 2014 to December 2017. MEASURES: Intervention delivery and practice implementation costs. Correlations of school demographics and administrator beliefs with costs. ANALYSIS: Intervention delivery activities micro-costed. Implemented practices assessed using costing template. RESULTS: Intervention schools: 234 implemented practices, control schools: 157. Twenty-month delivery costs: $29 310; $16 653 (per school: $320) for project staff, mostly mini-grants and coaching time. Administrator costs: $12 657 (per school: $243). Per-student delivery costs: $1.01. Costs of implemented practices: $641 843 for intervention schools (per-school mean: $12 343, median: $6 969); $496 365 for controls (per-school mean: $9365, median: $3123). Delivery costs correlated with implemented practices (0.37, P < .01) and total practice costs (0.37, P < .05). Implemented practices correlated with principal beliefs about the importance of skin cancer prevention to student health (0.46, P < .001) and parents (0.45, P < .001). CONCLUSION: Coaching of elementary school personnel can stimulate sun safety practice implementation at a reasonable cost. Findings can assist schools in implementing appropriate sun safety practices.

Family functioning, moods, and binge eating among urban adolescents.

This study builds upon prior research on associations between moods, family functioning, and binge eating, using ecological momentary assessment to examine moderating effects of family functioning on associations between moods and binge eating. This study was conducted among a nonclinical sample of urban adolescents. Family functioning was assessed using five constructs adopted from the FACES-IV measure: 'family cohesion,' 'family flexibility' 'family communication,' 'family satisfaction,' and 'family balance.' Mood data was gathered using 13 items from a daily affect scale. Binge eating was assessed using two subscales from the Eating Disorder Diagnostic Scale-binge eating associated with 'embarrassment' (BE1), and binge eating associated with a sense of 'loss of control' (BE2). A multilevel modeling approach was employed to examine how associations between momentary moods and binge eating behaviors were moderated by family functioning. Results indicated that measures of negative affect, stress/frustration, and tiredness/boredom were significantly and positively associated with two measures of binge eating (BE1 and BE2; p values ≤ 0.05), and that multiple factors of family functioning buffered the positive predictive effects of moods on binge eating. Findings indicate the importance of inclusion of family functioning in the development of eating behavior interventions for adolescents.

Acculturation and sugar-sweetened beverage consumption among Hispanic adolescents: The moderating effect of impulsivity.

Consumption of sugar-sweetened beverages is a risk factor for obesity. Acculturation to the United States (US) might increase sugar-sweetened beverage consumption among Hispanic adolescents, but few moderators of this relationship have been examined. This study examined the moderating influence of impulsivity on the association between acculturation and sugar-sweetened beverages. Hispanic adolescents (n = 154), 14-17 years, were identified and screened for eligibility through low-SES high schools and parents provided consent. Adolescents completed measures of acculturation using Unger's 8-item acculturation scale, impulsivity, and diet. Multiple linear regression was used to examine the main effect of acculturation and the interaction of acculturation with impulsivity on the diet outcomes: sugar-sweetened beverage consumption and percent of calories from sugar. Acculturation was positively associated with sugar-sweetened beverages (ß = 0.43; p < .05). The interaction of acculturation x impulsivity was significant (ß = 0.42, p < .05). Among youth who were more acculturated, those who were more impulsive consumed more sugar-sweetened beverages. Youth who were more acculturated, but less impulsive consumed less sugar-sweetened beverages. Neurocognitive variables such as impulsivity may be important moderators of the influence of acculturation on dietary behavior. Targeted messaging strategies based on levels of acculturation and impulsivity might enhance the effectiveness of interventions designed to reduce the intake of sugar-sweetened beverages among Hispanic adolescents.

Accuracy of Principal and Teacher Knowledge of School District Policies on Sun Protection in California Elementary Schools.

INTRODUCTION: Policy is a key aspect of school-based efforts to prevent skin cancer. We explored the extent and accuracy of knowledge among principals and teachers in California public school districts about the elements specified in their district's written sun safety policy. METHODS: The sample consisted of California public school districts that subscribed to the California School Boards Association, had an elementary school, adopted Board Policy 5141.7 for sun safety, and posted it online. The content of each policy was coded. Principals (n = 118) and teachers (n = 113) in elementary schools were recruited from September 2013 through December 2015 and completed a survey on sun protection policies and practices from January 2014 through April 2016. RESULTS: Only 38 of 117 principals (32.5%) were aware that their school district had a sun protection policy. A smaller percentage of teachers (13 of 109; 11.9%) than principals were aware of the policy (F108 = 12.76, P < .001). We found greater awareness of the policy among principals and teachers who had more years of experience working in public education (odds ratio [OR] = 1.05, F106 = 4.71, P = .03) and worked in schools with more non-Hispanic white students (OR = 7.65, F109 = 8.61, P = .004) and fewer Hispanic students (OR = 0.28, F109 = 4.27, P = .04). CONCLUSION: Policy adoption is an important step in implementing sun safety practices in schools, but districts may need more effective means of informing school principals and teachers of sun safety policies. Implementation will lag without clear understanding of the policy's content by school personnel.

Overweight Perception: Associations with Weight Control Goals, Attempts, and Practices among Chinese Female College Students.

BACKGROUND: Concurrent with the dramatic cultural and economic shifts occurring as mainland China becomes increasingly "Westernized," the weight perceptions, ideal body weight, and weight management goals and practices of Chinese females have also undergone significant changes. OBJECTIVE: To investigate relationships between overweight status, weight perception patterns, and weight management goals and practices in Chinese female college students. DESIGN/PARTICIPANTS/SETTING: A cross-sectional analysis was conducted with data from 902 female subjects aged 18 to 25 years participating in the China Seven Cities Study, a health promotion and smoking prevention study conducted in mainland China in 2003. MAIN OUTCOME MEASURES/STATISTICAL ANALYSES: Logistic regression models were used to explore associations between overweight status, weight perception, specific weight management goals and practices, and current levels of vigorous-intensity physical activity and food consumption. RESULTS: Based on World Health Organization standards for Asian adults, 16.7% of college females were overweight or obese, although 50.8% considered themselves to be "too heavy." Among participants perceiving themselves as overweight (n=458), 69.2% (n=371) were inaccurate and did not meet criteria for overweight or obese. The percentage of participants attempting weight loss was 48.2%, and 33.1% wanted to maintain their current weight. Attempts to lose or maintain weight were related to actual and perceived weight status, but not to increased vigorous-intensity physical activity or fruit and vegetable intake, nor to decreased consumption of sweets, soda, Western fast foods, and fried foods. Only 21.5% of participants desiring weight loss or maintenance reported using a combination of vigorous-intensity physical activity and a reduced-fat and -calorie diet, whereas 20.2% tried extreme methods such as fasting, using diet pills, vomiting, or smoking. CONCLUSIONS: Our findings underscore the need to promote healthy weight management practices among Chinese female college students, with an emphasis on diet and physical activity strategies that encourage balance rather than extremes.

A Longitudinal Analysis of the Effects of Socioeconomic Factors, Foreign Media, and Attitude toward Appearance on General and Central Adiposity in Chinese Adolescents.

OBJECTIVE: This paper explores the longitudinal effects of socioeconomic factors (i.e., parent education and family income level), foreign media, and attitude toward appearance on general and central adiposity among Chinese adolescents. METHOD: A longitudinal analysis was performed using data from the China Seven Cities Study, a health promotion and smoking prevention study conducted in seven cities across Mainland China between 2002 and 2005. Participants included 5,020 middle and high school students and their parents. Explanatory variables included foreign media exposure, attitude toward appearance, parent education, and family income. Three-level, random-effect models were used to predict general adiposity (i.e., body mass index) and central adiposity (i.e., waist circumference). The Generalized Estimating Equation approach was utilized to determine the effect of explanatory variables on overweight status. RESULTS: Among girls, foreign media exposure was significantly negatively associated with general adiposity over time (ß=-0.06, p=0.01 for middle school girls; ß=-0.06, p=0.03 for high school girls). Attitude toward appearance was associated with lesser odds of being overweight, particularly among high school girls (OR=0.86, p<0.01). Among boys, parental education was significantly positively associated with general adiposity (ß=0.62, p<0.01 for middle school boys; ß=0.37, p=0.02 for high school boys) and associated with greater odds of being overweight (OR=1.55, p<0.01 for middle school boys; OR=1.26, p=0.04 for high school boys). Across all gender and grade levels, family income was significantly negatively associated with central adiposity over time. CONCLUSION: Interventions addressing Chinese adolescent overweight/obesity should consider these factors as potential focus areas.

From ideas to efficacy: The ORBIT model for developing behavioral treatments for chronic diseases.

OBJECTIVE: Given the critical role of behavior in preventing and treating chronic diseases, it is important to accelerate the development of behavioral treatments that can improve chronic disease prevention and outcomes. Findings from basic behavioral and social sciences research hold great promise for addressing behaviorally based clinical health problems, yet there is currently no established pathway for translating fundamental behavioral science discoveries into health-related treatments ready for Phase III efficacy testing. This article provides a systematic framework for developing behavioral treatments for preventing and treating chronic diseases. METHOD: The Obesity-Related Behavioral Intervention Trials (ORBIT) model for behavioral treatment development features a flexible and progressive process, prespecified clinically significant milestones for forward movement, and return to earlier stages for refinement and optimization. RESULTS: This article presents the background and rationale for the ORBIT model, a summary of key questions for each phase, a selection of study designs and methodologies well-suited to answering these questions, and prespecified milestones for forward or backward movement across phases. CONCLUSIONS: The ORBIT model provides a progressive, clinically relevant approach to increasing the number of evidence-based behavioral treatments available to prevent and treat chronic diseases.

Ecological momentary assessment of urban adolescents' technology use and cravings for unhealthy snacks and drinks: differences by ethnicity and sex.

BACKGROUND: Adolescents' technology use is generally associated with food cravings, but it is not clear whether specific types of technology elicit particular types of cravings or whether personal characteristics play a role in these associations. OBJECTIVE: We examined whether momentary associations between four technology types (ie, television, video games, computer messaging, and phone messaging) and cravings for unhealthy snack foods and sweetened drinks were moderated by youths' sex, ethnicity, body mass index, and age. METHODS: Urban adolescents (N=158) aged 14 to 17 years provided momentary information about their technology use and food cravings during the course of 1 week and completed survey reports of their personal characteristics. We used multilevel modeling to determine momentary associations and interactions. RESULTS: Non-Hispanic adolescents showed stronger associations between television exposure and cravings for sweet snacks, salty snacks, and sweetened drinks. Being Hispanic was associated with stronger associations between phone messaging and cravings for sweet snacks, salty snacks, and sweetened drinks. Males showed stronger associations between video game use and salty snack cravings. CONCLUSIONS: As the public health field continues to monitor the effects of technology use on adolescents' eating and overall health, it will be important to determine the extent to which these groups are differentially affected by different forms of technology.

Recruitment results among families contacted for an obesity prevention intervention: the Obesity Prevention Tailored for Health Study.

BACKGROUND: Overweight and obesity are serious threats to health and increase healthcare utilization and costs. The Obesity Prevention Tailored for Health (OPT) study was designed to test the effectiveness of a family-based intervention targeting diet and physical activity. We describe the results of efforts to recruit parents and children enrolled in a large managed-care organization into the OPT study. METHODS: Parents with 10- to 12-year-old children were randomly selected from the membership of Kaiser Permanente Southern California, a large integrated health plan, and contacted between June 2010 and November 2011. We describe recruitment outcomes and compare characteristics of parents and children who did and did not participate. Information was collected from calls with parents and through the administrative and electronic medical records of the health plan. RESULTS: Of the 4,730 parents contacted, 16.1% expressed interest in participation (acceptors), 28.8% declined participation (refusers), 4.7% were ineligible, and, even after multiple attempts, we were unable to reach 50.4%. Slightly less than half of the acceptors (n = 361) were ultimately randomized to receive either the OPT program plus usual care or usual care alone (7.6% of all parents initially contacted). There were not any significant differences between acceptors who were or were not randomized. Overall, we found that acceptors were more likely to be female parents, have overweight/obese children, and higher utilization of outpatient visits by parents and children compared with refusers and those we were unable to reach. We found no differences in recruitment outcomes by body mass index or comorbidity score of the parents, level of physical activity of the parents and children, education of the parents, or household income. CONCLUSIONS: Recruiting parents and children into an obesity prevention program in a healthcare setting proved to be challenging and resource-intensive. Barriers and incentives for participation in obesity prevention programs need to be identified and addressed. Concern for the weight of their children may motivate parents to participate in family-based lifestyle interventions; however, the healthcare setting may be more relevant to weight-related treatment than to primary prevention.
