Project SHINE: effects of parent-adolescent communication on sedentary behavior in African American adolescents

Family systems approaches in pediatric obesity management: a scoping review

Family-based obesity management interventions targeting child, adolescent and parental lifestyle behaviour modifications have shown promising results. Further intervening on the family system may lead to greater improvements in obesity management outcomes due to the broader focus on family patterns and dynamics that shape behaviours and health. This review aimed to summarize the scope of pediatric obesity management interventions informed by family systems theory (FST). Medline, Embase, CINAHL and PsycInfo were searched for articles where FST was used to inform pediatric obesity management interventions published from January 1980 to October 2023. After removal of duplicates, 6053 records were screened to determine eligibility. Data were extracted from 50 articles which met inclusion criteria; these described 27 unique FST-informed interventions. Most interventions targeted adolescents (44%), were delivered in outpatient hospital settings (37%), and were delivered in person (81%) using group session modalities (44%). Professionals most often involved were dieticians and nutritionists (48%). We identified 11 FST-related concepts that guided intervention components, including parenting skills, family communication, and social/family support. Among included studies, 33 reported intervention effects on at least one outcome, including body mass index (BMI) (n = 24), lifestyle behaviours (physical activity, diet, and sedentary behaviours) (n = 18), mental health (n = 12), FST-related outcomes (n = 10), and other outcomes (e.g., adiposity, cardiometabolic health) (n = 18). BMI generally improved following interventions, however studies relied on a variety of comparison groups to evaluate intervention effects. This scoping review synthesises the characteristics and breadth of existing FST-informed pediatric obesity management interventions and provides considerations for future practice and research.

Translation of a family-based behavioral intervention for adolescent obesity using the RE-AIM framework and common steps from adaptation frameworks

Interventions for adolescent weight management that are ready to use in clinical settings are needed to address the obesity epidemic and improve the health and wellbeing of affected adolescents. This report describes the systematic process our team followed to adapt an evidence-based intervention (EBI) for adolescent weight management from its randomized control trial protocol to a package for delivery in a group-based telehealth format within a medical center. The EBI adaptation was clinician initiated, prompted by identified practice needs, and involved collaboration of the clinical team with the EBI developer. The process was guided by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework and followed key steps for adapting EBIs to new contexts. RE-AIM-aligned adaptations included telehealth delivery and broader inclusion criteria, separate clinical and research evaluation batteries, adaptations to fit the clinical practice, practical fidelity checklists to guide and record session delivery, and continuous quality improvement processes aimed to facilitate program longevity and family engagement. The process culminated in a package of adapted intervention materials deemed by stakeholders as appropriate to the practice and congruent with the EBI model. This report provides a much-needed practical demonstration of the translation of an EBI for adolescent weight management from research protocol to group telehealth delivery in a medical center. Key lessons include the value of clinician-researcher collaboration, the breadth of resources needed to adapt EBIs for real-world delivery, and the importance of considering delivery context in implementation and evaluation decisions, including defining inclusion criteria, staffing, and outcomes assessments.

Parent-based interventions to improve multiple lifestyle risk behaviors among adolescents: A systematic review and meta-analysis

Lifestyle risk behaviors often co-occur and are prevalent among adolescents. Parent-based interventions addressing risk behaviors concurrently have the potential to improve youth and parent outcomes. This systematic review evaluated the efficacy of parent-based interventions targeting multiple lifestyle risk behaviors among adolescents and parents. MEDLINE (Ovid), Embase (Ovid), PsycInfo (Ovid), Scopus, CINAHL, the Cochrane Database of Systematic Reviews (CDSR) and Cochrane Central Register of Controlled Trials (CENTRAL) were searched from 2010-May 2021. Eligible studies were randomised controlled trials (RCTs) of parent-based interventions addressing 2+ risk behaviors: alcohol use, smoking, poor diet, physical inactivity, sedentary behaviors, and poor sleep. Studies directly targeting parents, and that assessed adolescent outcomes (11-18 years) were eligible. Where possible, random-effects meta-analysis was conducted. From 11,975 identified records, 46 publications of 36 RCTs (n = 28,322 youth, n = 7385 parents) were eligible. Parent-based interventions were associated with improved adolescent moderate-to-vigorous physical activity (MVPA) [Odds Ratio (OR) = 1.82, 95% CI = 1.18, 2.81; p = 0.007], and reduced screen time (SMD = -0.39, 95% CI = -0.62, -0.16, p = 0.0009) and discretionary food intake (SMD = -0.18; 95% CI = -0.30, -0.06; p = 0.002) compared to controls. However, there was some evidence that interventions increased the odds of ever using tobacco in the medium-term (OR = 1.47, 95% CI = 0.99, 2.18, p = 0.06) and of past month tobacco use in the long-term (OR = 1.46, 95% CI = 1.12, 1.90; p = 0.005). Overall, the quality of evidence was moderate. Parent-based interventions targeting multiple risk behaviors improved adolescent MVPA, and reduced screen time discretionary food intake. Further research is needed to address sleep problems and increase intervention efficacy, particularly for alcohol and tobacco use.

Identifying effective intervention strategies to reduce children's screen time: a systematic review and meta-analysis

BACKGROUND

Excessive screen time ([Formula: see text] 2 h per day) is associated with childhood overweight and obesity, physical inactivity, increased sedentary time, unfavorable dietary behaviors, and disrupted sleep. Previous reviews suggest intervening on screen time is associated with reductions in screen time and improvements in other obesogenic behaviors. However, it is unclear what study characteristics and behavior change techniques are potential mechanisms underlying the effectiveness of behavioral interventions. The purpose of this meta-analysis was to identify the behavior change techniques and study characteristics associated with effectiveness in behavioral interventions to reduce children's (0-18 years) screen time.

METHODS

A literature search of four databases (Ebscohost, Web of Science, EMBASE, and PubMed) was executed between January and February 2020 and updated during July 2021. Behavioral interventions targeting reductions in children's (0-18 years) screen time were included. Information on study characteristics (e.g., sample size, duration) and behavior change techniques (e.g., information, goal-setting) were extracted. Data on randomization, allocation concealment, and blinding was extracted and used to assess risk of bias. Meta-regressions were used to explore whether intervention effectiveness was associated with the presence of behavior change techniques and study characteristics.

RESULTS

The search identified 15,529 articles, of which 10,714 were screened for relevancy and 680 were retained for full-text screening. Of these, 204 studies provided quantitative data in the meta-analysis. The overall summary of random effects showed a small, beneficial impact of screen time interventions compared to controls (SDM = 0.116, 95CI 0.08 to 0.15). Inclusion of the Goals, Feedback, and Planning behavioral techniques were associated with a positive impact on intervention effectiveness (SDM = 0.145, 95CI 0.11 to 0.18). Interventions with smaller sample sizes (n < 95) delivered over short durations (< 52 weeks) were associated with larger effects compared to studies with larger sample sizes delivered over longer durations. In the presence of the Goals, Feedback, and Planning behavioral techniques, intervention effectiveness diminished as sample size increased.

CONCLUSIONS

Both intervention content and context are important to consider when designing interventions to reduce children's screen time. As interventions are scaled, determining the active ingredients to optimize interventions along the translational continuum will be crucial to maximize reductions in children's screen time.

Families Improving Together (FIT) for weight loss: a resource for translation of a positive climate-based intervention into community settings

Climate-based weight loss interventions, or those that foster a nurturing family environment, address important ecological influences typically ignored by the traditional biomedical treatments. Promoting a climate characterized by positive communication, autonomy support, and parental warmth supports adolescents in making healthy behavioral changes. In addition, encouraging these skills within the family may have additional benefits of improved family functioning and other mental and physical health outcomes. Although several programs have identified essential elements and established the evidence base for the efficacy of these interventions, few have offered resources for the translation of these constructs from theoretical concepts to tangible practice. This paper provides strategies and resources utilized in the Families Improving Together (FIT) for weight loss randomized controlled trial to create a warm, supportive climate characterized by positive communication within the parent-child relationship. Detailed descriptions of how Project FIT emphasized these constructs through facilitator training, intervention curriculum, and process evaluation are provided as a resource for clinical and community interventions. Researchers are encouraged to provide resources to promote translation of evidence-based interventions for programs aiming to utilize a positive climate-based family approach for lifestyle modification.

A Strategic Plan for Strengthening America's Families: A Brief from the Coalition of Behavioral Science Organizations

Despite significant progress in research on the treatment and prevention of psychological, behavioral, and health problems, the translation of this knowledge into population-wide benefit remains limited. This paper reviews the state of America’s children and families, highlighting the influence of stressful contextual and social conditions on child and family well-being and the concentration of disadvantage in numerous neighborhoods and communities throughout the nation. It then briefly reviews the progress that has been made in pinpointing policies that can reduce stressful contextual conditions such as poverty, discrimination, and the marketing of unhealthful foods and substances. It also describes numerous family and school interventions that have proven benefit in preventing psychological and behavioral problems as diverse as tobacco, alcohol, and other drug use; depression; antisocial behavior; academic failure; obesity prevention; and early childbearing. We argue that progress in translating existing knowledge into widespread benefit will require a nationwide effort to intervene comprehensively in neighborhoods and communities of concentrated disadvantage. We present a strategic plan for how such an effort could be organized. The first step in this organizing would be the creation of a broad and diverse coalition of organizations concerned with advancing public health and well-being. Such a coalition could increase public support both for the policies needed to focus on these disadvantaged areas and the research needed to incrementally improve our ability to help these areas.

Adolescent Girls With Overweight and Obesity Feel Physically Healthy and Highlight the Importance of Mental Health

Introduction

Obesity in adolescence is a significant ongoing public health problem that has not improved over the past decade.

Objective

This descriptive qualitative study explores the perspective of female adolescents who are overweight or obese regarding their views on health and weight within the clinic setting.

Methods

In-depth interviews were conducted with female adolescents (age 13–19 years old; BMI ≥85th percentile) from the mid-west region of the United States (N = 28). Inductive thematic analysis using Braun & Clarke’s methods was utilized.

Results

The findings from this study revealed that the adolescents’ view of health encompasses physical, mental, and psychosocial health dimensions, and despite being overweight and obese, the participants felt healthy. Participants discussed the need to eat healthier and increase their daily physical activity, but were unable to transform this into action. Within the clinical setting, the adolescents were sensitive to weight discussions.

Conclusion

Results from this study can increase providers’ understanding of the adolescent, increase awareness of adolescent sensitivity, and assist researchers in developing age-appropriate interventions for effective treatment and prevention of childhood obesity.

Female adolescents with overweight and obesity share their perspectives on the clinical setting and weight management

The clinical setting remains a strategic environment for early assessment, identification and treatment of adolescents with obesity. Yet, healthcare providers' (HCPs) efforts have been unsuccessful in improving physical activity, nutritional intake or body mass index in adolescents with obesity. Obesity is a chronic condition that influences how patients interact with HCPs and experience ambulatory healthcare appointments. However, it is unknown how female adolescents with obesity perceive the clinical setting, especially regarding weight management. The purpose of this study was to explore the perceptions of female adolescents with obesity regarding health and weight management in the clinical setting. Using a qualitative design, 28 English-speaking female adolescents, 13 to 19 years of age, with a body mass index ≥85th percentile for height and weight participated in individual interviews. Results demonstrate that adolescents with obesity desire to be recognized as unique individuals and to be involved in their own health conversations. The participants reported that their health care was inadequate when they received impersonal and vague advice from HCPs on weight loss. Weight-related communication was best received in a kind and empathetic manner, with a focus on improving one's health (instead of losing weight). Adolescents in this study articulated the components of healthy eating and physical exercise, yet were unable to synthesize this knowledge into specific dietary practices and daily physical activities. The insights derived from female adolescents with obesity provide guidance on how HCPs can improve their relationship and engage the adolescent in weight-based discussions. Concrete, actionable recommendations are provided for providers who work with female adolescents who are overweight or obese.

Parent Involvement in Adolescent Obesity Treatment: A Systematic Review

CONTEXT

Family-based lifestyle interventions are recommended for adolescent obesity treatment, yet the optimal role of parents in treatment is unclear.

OBJECTIVE

To examine systematically the evidence from prospective randomized controlled and/or clinical trials (RCTs) to identify how parents have been involved in adolescent obesity treatment and to identify the optimal type of parental involvement to improve adolescent weight outcomes.

DATA SOURCES

Data sources included PubMed, PsychINFO, and Medline (inception to July 2019).

STUDY SELECTION

RCTs evaluating adolescent (12-18 years of age) obesity treatment interventions that included parents were reviewed. Studies had to include a weight-related primary outcome (BMI and BMI z score).

DATA EXTRACTION

Eligible studies were identified and reviewed, following the Preferred Reporting for Systematic Review and Meta-Analyses guidelines. Study quality and risk of bias were evaluated by using the Cochrane Collaboration risk of bias tool.

RESULTS

This search identified 32 studies, of which 23 were unique RCTs. Only 5 trials experimentally manipulated the role of parents. There was diversity in the treatment target (parent, adolescent, or both) and format (group sessions, separate sessions, or mixed) of the behavioral weight loss interventions. Many studies lacked detail and/or assessments of parent-related behavioral strategies. In ∼40% of unique trials, no parent-related outcomes were reported, whereas parent weight was reported in 26% and associations between parent and adolescent weight change were examined in 17%.

LIMITATIONS

Only RCTs published in English in peer-reviewed journals were eligible for inclusion.

CONCLUSIONS

Further research, with detailed reporting, is needed to inform clinical guidelines related to optimizing the role of parents in adolescent obesity treatment.

Open trial of the Parent Behavior Change Intervention (PBC-I): Study protocol

OBJECTIVE

Parents have profound impacts on adolescents' health behaviors. Yet parents receive minimal training in the elements of conversations that optimally inspire their children toward engaging in healthy behaviors. The current study examines a novel interpersonal target: parent-adolescent conversations about adolescent health behavior change. Derived from advances in the science of behavior change, the Parent Behavior Change Intervention (PBC-I) contains conversational elements (e.g., behavior change techniques, positive communication strategies) hypothesized to reduce parent-adolescent coercion and conflict and facilitate upward spirals of healthy behavior change in adolescents.

METHOD/DESIGN

The first phase of the study involves the development of the PBC-I in a small case series (N = 12 dyads). The second phase involves an open trial of the PBC-I (N = 36 dyads). Adolescents will receive six 50-min sessions of the Transdiagnostic Sleep and Circadian Intervention to improve sleep while their parents receive six50-min sessions of the PBC-I. Parent-adolescent dyads will be assessed before and after the intervention. The primary analysis will examine whether postintervention use of behavior change techniques and positive communication strategies by parents is higher than preintervention use and whether increased use by parents predicts more positive conversational behaviors, less parent-adolescent conflict, higher adolescent motivation for change, and improved adolescent sleep.

DISCUSSION

This research provides an initial test of the hypothesis that improving the parent-adolescent conversation will improve adolescent sleep health behavior. While sleep-related health behaviors are the focus of this study, the research is designed to be relevant to a broad range of health behavior change in young people.

Secondary benefits of the families improving together (FIT) for weight loss trial on cognitive and social factors in African American adolescents

BACKGROUND

Although weight loss is an important primary outcome in obesity interventions, family-based interventions may have cascading ripple effects that extend to other aspects of health and well-being. Identifying these secondary benefits may be useful for understanding how to best engage underserved African American families in weight loss. The present research examines whether African American adolescents and parents perceive secondary benefits from participating in a family-based weight-loss intervention, including secondary health, social, or cognitive benefits.

METHODS

Qualitative data were obtained from families participating in the group-based intervention of the Families Improving Together (FIT) for Weight Loss trial. During the final week of the face-to-face motivational and family-based intervention program, families completed a guided open-ended group discussion about changes they experienced from participating (14 groups, N = 41 adolescents and 41 parents). Sessions were audiotaped, transcribed, and coded by independent pairs of raters using both inductive and deductive approaches. Guided by the multi-theoretical framework for the FIT trial, some themes were determined prior to coding using a deductive approach, including: (a) health outcomes (e.g., monitoring strategies for diet and physical activity), (b) social outcomes (e.g., involvement in family support, group support, autonomy support, family bonding, positive communication) and (c) cognitive outcomes (e.g., expression of self-confidence through self-efficacy, self-regulation, establishment of long-term goals). In addition to these pre-determined themes, the coding process included an inductive assessment, allowing for unexpected themes to surface as well around positive self-talk, relapse prevention, and monitoring strategies for different types of weight-related behaviors.

RESULTS

Across both adolescents and parents, the cognitive outcomes were the most frequently discussed outcomes, including self-regulation, monitoring strategies for diet, establishing long-term goals, and ultimate relapse prevention. Parents made a greater number of comments about the social outcomes, including family support, group support, self-efficacy, and family connectedness, whereas adolescents made a greater number of comments about positive family communication.

CONCLUSIONS

The results provide preliminary support for the positive secondary effects of weight loss programs on improving both cognitive and social well-being in underserved African American adolescents.

Perceived barriers and facilitators for healthy behaviours among parents of adolescents receiving mental health care in a public hospital in Cape Town, South Africa: A qualitative study

Objective: To explore the perceived barriers and facilitators for healthy behaviours among parents and caregivers of adolescents receiving mental health care in Cape Town, South Africa. Method: Thirty-five qualitative in-depth interviews were conducted with parents and caregivers of adolescents receiving mental health treatment by six facilitators matched for language. The data was analysed using thematic analysis. Results: The participants were predominantly female (n = 28, 80%) and parents (n = 29, 83%) of the adolescents. Personal barriers to good health included unhealthy eating, substance use and physical inactivity. Environmental barriers were inherited medical conditions, the easy availability of unhealthy foods and the absence of recreational facilities in communities. Perceived facilitators to good health were parental role modelling, planning and preparing healthy meals, exercise opportunities providing by walking long distances to work, and doing physically demanding jobs and household chores. Conclusion: Parents and caregivers are essential to adolescents' healthy development as they may influence adolescent health behaviours. It is likely that the promotion of positive health behaviours may be achieved though family-based interventions.

Familias Unidas for Health and Wellness: Adapting an Evidence-Based Substance Use and Sexual Risk Behavior Intervention for Obesity Prevention in Hispanic Adolescents

We describe the adaptation of Familias Unidas, an evidence-based substance use and sexual risk behavior intervention, for obesity prevention in Hispanic adolescents. Intervention developers and experts in pediatric obesity, exercise physiology, dietetics, and the local parks system provided input for changes. Hispanic families also provided input through a series of 21 focus groups conducted before, during, and after an initial pilot test of the adapted intervention. After transcribing audiotaped sessions, we used a general inductive approach and Dedoose qualitative software to derive themes. Results indicated the need for improved health-related family functioning, enhanced nutrition education and skill building, increased family engagement in physical activity, and stronger links between family and environmental supports. Parents who participated in the pilot test expressed high enthusiasm for hands-on nutrition training and reported improvements in family functioning. Adolescents liked outdoor physical activities but wanted parents to be more engaged in joint physical activity sessions. The adapted intervention maintains fidelity to Familias Unidas' core theoretical elements and overall structure, but also includes content focused on physical activity and nutrition, adolescent participation in physical activity sessions led by park coaches, and joint parent-adolescent participation in physical activity and nutrition skill-building activities.

Project SHINE: effects of a randomized family-based health promotion program on the physical activity of African American parents

This study examined the effects of a family-based health promotion intervention on the moderate-to-vigorous physical activity (MVPA), light physical activity, sedentary behavior, and fruit and vegetable intake of African American parents. Eighty-nine African American parents (41.5 ± 8.5 years; 92% females; 74% obese; 64% < $40 K income) and adolescents (12.5 ± 1.4 years; 61% girls; 48% obese) were randomized to a 6-week behavioral skills plus positive parenting and peer monitoring intervention grounded in social cognitive, self-determination, and family systems theories or a general health comparison program. Parents wore accelerometers for 7 days and completed three 24-h dietary recalls at baseline and post-intervention. Multilevel regression models (controlling for baseline variables) demonstrated a significantly greater increase in parent MVPA for those in the intervention versus comparison condition (b = 9.44, SE = 4.26, p < 0.05). There were no other significant effects. Family-based approaches that include African American parents and youth may increase parent MVPA and hold promise for preventing chronic diseases.

Promoting Social Nurturance and Positive Social Environments to Reduce Obesity in High-Risk Youth

Nurturing environments within the context of families, schools, and communities all play an important role in enhancing youth's behavioral choices and health outcomes. The increasing prevalence rates of obesity among youth, especially among low income and ethnic minorities, highlight the need to develop effective and innovative intervention approaches that promote positive supportive environments across different contexts for at-risk youth. We propose that the integration of Social Cognitive Theory, Family Systems Theory, and Self-Determination Theory offers a useful framework for understanding how individual, family, and social-environmental-level factors contribute to the development of nurturing environments. In this paper, we summarize evidence-based randomized controlled trials that integrate positive parenting, motivational, and behavioral skills strategies in different contexts, including primary care, home, community, and school-based settings. Taken together, these studies suggest that youth and parents are most likely to benefit when youth receive individual-level behavioral skills, family-level support and communication, and autonomous motivational support from the broader social environment. Future investigators and healthcare providers should consider integrating these evidence-based approaches that support the effects of positive social climate-based interventions on promoting healthy eating, physical activity, and weight management in youth.

Associations Between Parenting Factors, Motivation, and Physical Activity in Overweight African American Adolescents

Background

Positive parenting practices and environmental supports have been linked to physical activity (PA) levels in youth, yet factors associated with positive parenting styles have been understudied in African American adolescents.

Purpose

This study expands on previous literature by examining associations between motivation, parenting factors associated with Self-Determination Theory's psychological needs (competence, autonomy, and relatedness) including authoritative parenting, autonomy support and emotional and tangible support, and adolescent moderate-to-vigorous PA (MVPA) and light PA (LPA).

Methods

Participants were African American adolescents (N = 148; Mage = 13.6 years; MBMI% = 96.6) and their care-givers (Mage = 43.4 years; MBMI = 37.4) enrolled in the Families Improving Together for Weight Loss trial. Parenting factors were measured using self-report surveys, and PA minutes were measured using 7-day accelerometry estimates.

Results

Regression analyses indicated that overall models for MVPA (F(11,134) = 4.35; R2 = 0.26) and LPA (F(11,134) = 5.84, R2 = 0.32) were significant. Adolescent motivation for PA (B = 0.58, SE = 0.16) was positively associated with MVPA minutes. Authoritative parenting (B = 15.71, SE = 4.38) and tangible support (B = 8.53, SE = 4.02) were positively associated with adolescent LPA minutes. Unexpectedly, emotional support was negatively associated with both MVPA (B = -0.47, SE = 0.17) and LPA (B = -11.22, SE = 4.79), with follow-up analyses showing this relationship stronger in males.

Conclusion

Findings highlight the importance of adolescent motivation for PA onMVPA and positive parenting styles and tangible supports on adolescent LPA in overweight African American youth. Recommendations for integrating these factors within the context of intervention studies are discussed.

Engaging African American Adolescents and Stakeholders to Adapt Interpersonal Psychotherapy for Weight Gain Prevention

Developing culturally appropriate obesity prevention programs for African American (AA) adolescent girls that account for psychological risk factors is paramount to addressing health disparities. The current study was part of an investigation utilizing a community-based participatory research framework to gather qualitative data from urban AA girls, their caregivers, and community health liaisons to develop a novel obesity prevention program based on interpersonal psychotherapy for the prevention of excessive weight gain (IPT-WG). In the current study with urban AAs, data from seven focus groups (total sample size, N = 40) were analyzed using thematic analysis. Participants identified problematic eating behaviors, including binge or loss of control eating; highlighted the importance of interpersonal relationships, mood functioning, and eating; and supported the tenets of IPT-WG. While features of IPT-WG generally resonated with participants, culturally based modifications were suggested. These data will be used to inform the development of a culturally relevant IPT-WG program.

[Reduce sedentary behaviour among children - a systematic review]

BACKGROUND AND OBJECTIVES

Sedentary behaviour is itself a health-related behaviour. This systematic review examines whether family-based interventions can reduce sitting time among children and adolescents and which variables moderate potential intervention effects.

METHODS

Using a systematic literature search we identified family-based randomised controlled intervention studies that focus on sedentary behaviour in 3‑ to 18-year-old children and youth. The methodological quality of studies as well as the intervention effects according to different outcomes (screen-based vs. overall sitting) were analysed and evaluated for moderating effects.

RESULTS

Of 29 studies, 17 reported significant effects and 11 studies showed positive trends for reduced sitting time. The content of interventions, the level of theoretical underpinning as well as the methodological quality of studies were heterogeneous. Most often, screen-based sitting and seldom overall sitting was examined. Concise characteristics of intervention success were not clearly apparent. The proportion of positive intervention effects was higher in reducing sitting in front of TVs compared to other outcomes. An analysis of moderators highlighted that intervention programs among pre-schoolers showed more often positive intervention effects.

DISCUSSION

There are many promising opportunities to reduce sitting time using family-based approaches. Statements in terms of replication of interventions and explanations of the effective mechanisms within interventions are limited. Therefore, future interventions should use subjective as well as objective evaluation measures and consider overall sitting time. To strengthen the basis of interventional effort in this research field, a theoretical planning approach is recommended.

Reliability of 24-Hour Dietary Recalls as a Measure of Diet in African-American Youth

BACKGROUND

Although it is a common practice to estimate dietary intake using three random 24-hour dietary recalls, some studies have suggested up to nine may be necessary to reliably estimate usual intake in youth. Given the resulting increase in resources and participant burden, more research is needed to determine whether this method is reliable, particularly in African-American youth at increased risk for obesity and other chronic diseases.

OBJECTIVE

This study estimated the reliability with which 24-hour dietary recalls measure energy, fat, fruit, and vegetable intake in African-American youth and examined how reliability changes as a function of the number of recalls.

DESIGN

This study used cross-sectional data collection across three studies.

PARTICIPANTS/SETTING

Participants were African-American youth (n=456, mean±standard deviation age 13.28±1.86 years, 64% were girls, mean±standard deviation body mass index [calculated as kg/m(2)] 31.45±7.94) who completed random 24-hour dietary recalls (67% completed three) conducted by research assistants using the Automated Self-Administered 24-Hour recall system (n=258) or registered dietitian nutritionists using the Nutrition Data System for Research (n=198).

MAIN OUTCOME MEASURES/STATISTICAL ANALYSES

Estimates provided by multilevel models were used to calculate the proportion of variance accounted for between individuals and the reliability of means within individuals as a function of the number of recalls.

RESULTS

Reliability estimates for assessing dietary outcomes using one to three recalls ranged from 11% to 62%. To achieve 80% reliability, the following number of recalls would need to be conducted: 8 for energy intake, 13 for fat intake, 21 to 32 for fruit intake, and 21 to 25 for vegetable intake.

CONCLUSIONS

The common practice of assessing dietary intake with three recalls does so with low reliability in African-American youth. Until more objective methods for reliably estimating usual intake are developed, researchers who choose to use 24-hour dietary recalls are encouraged to include estimates of the measure's reliability in a priori power calculations for improved decision making regarding the number of observations and/or sample size.

Process Evaluation of the Project SHINE Intervention for African American Families: An Integrated Positive Parenting and Peer Monitoring Approach to Health Promotion

This study describes the process evaluation of Project SHINE, a randomized family-based health promotion intervention that integrated parenting and peer monitoring for improving sedentary behavior, physical activity, and diet in African American families. Adolescent-parent dyads (n = 89) were randomized to a 6-week behavioral, positive parenting, and peer monitoring skills intervention or a general health education comparison condition. Process evaluation included observational ratings of fidelity, attendance records, psychosocial measures, and qualitative interviews. Results indicated that the intervention was delivered with high fidelity based on facilitator adherence (>98% of content delivered) and competent use of theoretically based behavior change and positive parenting skills (100% of ratings >3 on a 1-4 scale). Although only 43% of peers attended the "bring a friend" session, overall attendance was high (4.39 ± 1.51 sessions) as was the retention rate (88%). Parents in the intervention condition reported significant improvements in communication related to adolescents' engagement in health behaviors both on their own and with peers. These findings were supported by qualitative themes related to improvements in family communication and connectedness. This study provides an innovative example of how future family-based health promotion trials can expand their process evaluation approaches by assessing theoretically relevant positive parenting variables as part of ongoing monitoring.

An exploratory factor analysis of the Parenting strategies for Eating and physical Activity Scale (PEAS) for use in Hispanic mothers of adolescent and preadolescent daughters with overweight

Existing measures of feeding and physical activity parenting strategies have not been validated for use among Hispanic mothers of adolescent and preadolescent daughters with overweight. The purpose of this study was to investigate the factor structure of the Parenting strategies for Eating and Activity Scale (PEAS) among 134 Hispanic mothers (Mage=38.81, SD±6.34) of adolescent and preadolescent daughters with overweight. Results from this exploratory study revealed that a three-factor structure (Limit Setting, Monitoring, and Discipline) and a 13-item revised PEAS measure might be better suited for use with this population. The revised Limit Setting, Monitoring, Discipline, and total subscales had good reliability (α=0.89, α=0.88, α=0.90, and α=0.87, respectively) and the subscale inter-item correlations were strong. To assess the concurrent validity, the revised PEAS subscales were correlated with both subscales of the Behavioral Strategies to Reduce Fat and Increase Fiber (Parent Report) in a subset of the sample (n=78). The Monitoring and Discipline subscales were found to be correlated with the Behavioral Strategies to Reduce Fat (r=.36 and r=.27, p<.05, respectively) and Increase Fiber (r=.40 and r=.35, p<.01, respectively) subscales. However, the revised PEAS Limit Setting subscale was not correlated with either Reduce Fat or Increase Fiber strategy. Taken together, these results indicated some degree of concurrent validity. Results from this study should be cross-validated using confirmatory factor analysis approaches.

Commentary: Pediatric obesity: systems science strategies for prevention

OBJECTIVES

Pediatric obesity is a major public health problem that undermines the physical and mental health of children and increases their risk for adult obesity and other chronic illnesses. Although health care providers, including pediatric psychologists, have implemented prevention programs, effects have been minimal, with no solid evidence of sustainable programs.

METHODS

A systems science framework that incorporates the multiple interacting factors that influence pediatric obesity may be useful in guiding prevention.

RESULTS

The National Prevention Strategy provides recommendations that can be incorporated into systems science designs, including (1) Healthy and Safe Environments, (2) Clinical and Community Preventive Services, (3) Empowering People, and (4) Elimination of Health Disparities. In addition, our recommendation is that future obesity prevention programs target early in life (pre-pregnancy through toddlerhood) and use multilevel multidisciplinary designs.

CONCLUSIONS

The benefits of preventing pediatric obesity extend from the health and well-being of individual children to the economic security of the nation.

Context matters in pediatric obesity: commentary on innovative treatment and prevention programs for pediatric overweight and obesity

This commentary reviews the 9 articles in the Special Issue on Innovative Treatment and Prevention Programs for Pediatric Overweight and Obesity. Taking a socio-ecological perspective, contextual factors such as characteristics of the child, family, community, and culture are offered as ways to improve treatment and prevention programs. Using a more tailored approach that takes into account individual differences in family communication patterns and problem solving is warranted. Pediatric psychologists are urged to consider the role of prevention and targeted efforts during early childhood to reduce the prevalence of childhood obesity.

A pilot study of the effects of a tailored web-based intervention on promoting fruit and vegetable intake in African American families

BACKGROUND

The current study examined the effects of a Web-based tailored parenting intervention on increasing fruit and vegetable intake in African American families.

METHODS

Forty-seven African American parents (mean age, 41.32 ± 7.30; 93.6% female) with an adolescent (mean age, 13.32 ± 1.46; 59.6% female) participated in a Web-based autonomy-support parenting tailored intervention session to increase both parent and youth fruit and vegetable (F&V) intake. The session lasted 45-60 minutes and included three phases: a feedback phase; a Web-based information phase, and a goal-setting and action plan phase. Self-reported measures of parenting skills [based on autonomy (choice), support, and communication] and F&V intake (assessed as average daily intake) were assessed at baseline and at a 1-week follow-up session.

RESULTS

There was a significant increase in parents' self-reports of daily fruit intake from pretest to the 1-week follow-up. Parent and adolescent combined F&V intake also significantly increased from pretest to 1-week follow-up. Overall, parents reported that the program was easy to navigate and that they enjoyed participating in the Web-based online program.

CONCLUSIONS

Current findings provide preliminary support for an autonomy-support parent tailored Web-based program for improving dietary intake in African American families.

Feasibility and preliminary outcomes from a pilot study of an integrated health-mental health promotion program in school mental health services

The prevalence of unmet health and mental health needs among youth has spurred the growing consensus to develop strategies that integrate services to promote overall well-being. This pilot study reports on the feasibility and outcomes of a theory-driven, family-focused, integrated health-mental health promotion program for underserved adolescents receiving school mental health services. Parent and adolescent assessments conducted prior to and following the brief, 6-session promotion program showed significant improvements in family support, youth self-efficacy, health behaviors, and mental health outcomes. Clinician reports contributed to a characterization of the feasibility, acceptability, and future recommendations for the integrated program.
