Motivational interviewing for pediatric obesity: Conceptual issues and evidence review

Motivational Interviewing for the Prevention and Treatment of Pediatric Obesity: A Primer

Motivational interviewing (MI), which is recommended for prevention and treatment of pediatric obesity, is a patient-centered counseling style used to modify behaviors. When using MI, pediatric providers generally avoid direct attempts to convince or persuade. Instead, they help patients or parents think about and verbalize their reasons for and against change and how their behavior aligns with their values and goals. MI relies on specific techniques, including reflective listening, to strategically balance the need to "comfort the afflicted" and "afflict the comfortable"; to balance the expression of empathy with the need to build discrepancy for change, thereby encouraging "change talk".

Mobilizing faith-based COVID-19 health ambassadors to address COVID-19 health disparities among African American older adults in under-resourced communities: A hybrid, community-based participatory intervention

INTRODUCTION

The COVID-19 pandemic disproportionately affected older adults, particularly those with pre-existing chronic health conditions. To address the health disparity and challenges faced by under-resourced African American older adults in South Los Angeles during this period, we implemented a hybrid (virtual/in-person), pre-post, community-based participatory intervention research project utilizing a faith-based lay health advisor model (COVID-19 Health Ambassador Program (CHAP)). We recruited COVID-19 Health Ambassadors (CHAs) and African American older adults (participants) from faith-based organizations who partook in CHA-led meetings and follow-ups that educated and supported the participants. This paper seeks to evaluate this intervention's implementation using the Consolidated Framework for Implementation Research (CFIR) as a reporting tool with an emphasis on fidelity, challenges, and adaptations based on data collected via stakeholder interviews and surveys.

RESULTS

CHAP was delivered to 152 participants by 19 CHAs from 17 faith-based organizations. CHAs assisted with chronic disease management, resolved medication-related challenges, encouraged COVID-19 vaccination, reduced psychological stress and addressed healthcare avoidance behaviors such as COVID-19 vaccine hesitancy among the participants. Challenges encountered include ensuring participant engagement and retention in the virtual format and addressing technological barriers for CHAs and participants. Adaptations made to better suit the needs of participants included providing communication tools and additional training to CHAs to improve their proficiency in using virtual platforms in addition to adapting scientific/educational materials to suit our participants' diverse cultural and linguistic needs.

CONCLUSION

The community-centered hybrid approach in addition to our partnership with faith-based organizations and their respective COVID-19 health ambassadors proved to be essential in assisting underserved African American older adults manage chronic health conditions and address community-wide health disparities during the COVID-19 pandemic. Adaptability, cultural sensitivity, and teamwork are key to implementing health interventions especially in underserved populations.

Randomized-controlled trial of a whole-family obesity prevention and treatment intervention designed for low-income Hispanic families: HeLP the healthy living program

BACKGROUND

Low-income Hispanic families face marked disparities in obesity, but interventions for obesity prevention and treatment have rarely been designed with this population as a focus. Hispanic culture is characterized by Familism, a value that prioritizes familial respect, cooperation, and togetherness. We describe the rationale and design of a trial of the Healthy Living Program (HeLP), a bilingual whole-family behavioral obesity prevention and treatment intervention designed around the value Familism and addressing food insecurity.

METHODS/DESIGN

This two-group randomized comparative effectiveness trial will compare the effects of HeLP versus a primary care counseling intervention (Recommended Treatment of Obesity in Primary Care, or RTOP) on decreasing body mass index (BMI; kg/m2) in Hispanic children 2-16 years of age with obesity and preventing BMI increase among siblings without obesity. 164 families per arm will be recruited from primary care practices. Families randomized to HeLP will participate in 12 two-hour sessions, followed by booster sessions. HeLP sessions include family meals and instruction in parenting skills, nutrition, culinary skills, fitness, and mindfulness delivered at community recreation centers by bilingual health educators and athletic trainers. Families randomized to RTOP will be offered individual visits in primary care every 3 months throughout the 18-month follow-up period. Secondary outcomes include changes to objectively measured child fitness, the home environment related to nutrition, physical activity, and media usage, food insecurity, child eating behaviors, quality of life, parent BMI and waist circumference, and implementation outcomes.

DISCUSSION

This protocol paper describes the rationale and planned methods for the comparative effectiveness trial.

Motivational interviewing for the management of child and adolescent obesity: a systematic literature review

BACKGROUND

Among children or adolescents with obesity, 40-70.5% will remain obese as adults according to their paediatric body mass index (BMI). The recommended management involves changes in their nutritional habits (diet, physical activity, and sedentary lifestyle). Motivational interviewing (MI), a patient-centred consultation, has proven its worth in many fields where acting on behaviours is essential.

AIM

To investigate the use and outcomes of MI in the management of children and adolescents who are overweight and obese.

DESIGN & SETTING

A systematic review evaluated MI in the management of children and adolescents who are overweight and obese.

METHOD

PubMed, Web of Science, Cochrane Library, and CISMeF were searched between January 2022 and March 2022 for following terms: 'motivational interviewing', 'overweight or obesity', 'children or adolescent' to identify randomised controlled trials (RCTs). Inclusion criteria were interventions involving MI in children or adolescents who were commonly (polygenically) overweight or obese. Exclusion criteria were: studies before 1991; and articles not written in English or French. The first stage of the selection process was carried out by reading the titles and abstracts. A second stage was carried out by reading the complete studies. A secondary inclusion of articles was carried out following the reading of bibliographic references, mainly from systematic reviews and meta-analyses. The data were summarised in synthetic tables based on the Population, Intervention, Comparison, Outcomes, and Study (PICOS) tool.

RESULTS

From 444 articles the review identified 26 RCTs. Statistically significant results were found for all criteria (anthropometric and behavourial) in both children and adolescents. Quality of life and depression scores were also improved. Parental presence in the interview appeared to be essential for children, whereas for adolescents, the supportive involvement of parents outside of the interviews seemed more appropriate. The frequency and duration of the interventions played a major role in obtaining results, as did the number of people involved, and the diversity of the places where they are taken care of.

CONCLUSION

MI seems promising for children and adolescents with overweight or obesity, within the framework of a comprehensive, multiprofessional, family management, carried out over a long period with regular consultations.

Food Parenting Practices Promoted by Childcare and Primary Healthcare Centers in Chile: What Influences Do These Practices Have on Parents? A Qualitative Study

Chile, like many other countries in the world, is experiencing a high prevalence of childhood overweight. Among the factors influencing children's eating behaviors are the food parenting practices promoted by community organizations. More information is needed on the influences of these recommendations on the parenting practices of parents of preschoolers. This study examined what types of food parenting practices are promoted in childcare and primary healthcare centers and how these recommendations influence subsequent parental behavior. Interviews using photo-elicitation were conducted with 25 parents of Chilean preschoolers. The interviews were analyzed using inductive thematic analysis. Five themes were identified to describe food parenting practices promoted by community organizations and the influences that these practices had on parents of preschoolers. Healthcare centers were found to educate parents and provided a structured feeding. However, parents found their advice regarding dietary restriction challenging to follow. Childcare centers also provided information about healthy diet, food monitoring, and diversifying the child's diet in a way that was perceived as adequate. While childcare centers encouraged structured and autonomous food parenting practices in a positive and supportive manner, healthcare centers tended to provide more restrictive guidance that posed challenges for parents struggling with preschool nutritional care.

Challenges and Opportunities in Diagnosis and Management of Cardiometabolic Risk in Adolescents

PURPOSE OF REVIEW

This review aims to elucidate the limitations of diagnosing metabolic syndrome in adolescents as well as challenges and opportunities in the identification and reduction of cardiometabolic risk in this population.

RECENT FINDINGS

There are multiple criticisms of how we define and approach obesity in clinical practice and scientific research, and weight stigma further complicates the process of making and communicating weight-related diagnoses. While the goal of diagnosing and managing metabolic syndrome in adolescents would be to identify individuals at elevated future cardiometabolic risk and intervene to reduce the modifiable component of this risk, there is evidence that identifying cardiometabolic risk factor clustering may be more useful in adolescents than establishing a cutoff-based diagnosis of metabolic syndrome. It has also become clear that many heritable factors and social and structural determinants of health contribute more to weight and body mass index than do individual behavioral choices about nutrition and physical activity. Promoting cardiometabolic health equity requires that we intervene on the obesogenic environment and mitigate the compounding effects of weight stigma and systemic racism. The existing options to diagnose and manage future cardiometabolic risk in children and adolescents are flawed and limited. While striving to improve population health through policy and societal interventions, there are opportunities to intervene at all levels of the socioecological model in order to decrease future morbidity and mortality from the chronic cardiometabolic diseases associated with central adiposity in both children and adults. More research is needed to identify the most effective interventions.

Motivational Interviewing in Pediatric Obesity: A Meta-analysis of the Effects on Behavioral Outcomes

BACKGROUND

Currently, the effects of motivational interviewing (MI) on children's behavioral changes remain obscure.

PURPOSE

This systematic review and meta-analysis examined the effects of MI on children's lifestyle behavioral changes (fruits and vegetables [F/V], dairy, sugary beverages, calories, snacks, fat intake, moderate vigorous physical activity [MVPA], and screen time).

METHODS

Six databases (CINAHL, Cochrane, Embase, PsycINFO, PubMed, and Web of Sciences) from 2005 to 2022 were searched. Thirty-one intervention studies with a comparison group met the criteria. Random-effects models were performed to estimate the pooled effects; exploratory moderation analyses with mixed-effects models were used to explore potential intervention moderators.

RESULTS

The pooled effect size was 0.10 (p = .334) on ↑F/V, 0.02 (p = .724) on ↑dairy, -0.29 (p < .001) on ↓calories, -0.16 (p = .054) on ↓sugary beverages, -0.22 (p = .002) on ↓snacks, -0.20 (p = .044) on ↓fat, 0.22 (p = .001) on ↑MVPA, and -0.06 (p = .176) on ↓screen time. The effects of MIs were moderated by ↑MI sessions regarding ↓snacks (B = -0.04, p = .010). Multicomponent and clinical programs had greater effects on dairy intake than their counterparts (0.09 vs. -0.21, p = .034; 0.12 vs. -0.14, p = .027, respectively). Similarly, interventions with a fidelity check resulted in greater dairy intake than those without a check (0.29 vs. -0.15, p = .014). A few long-term follow-up assessments revealed effects on ↓F/V (-0.18; p = .143, k = 2), ↓dairy (-0.13, p = .399, k = 4), ↓MVPA (-0.04; p = .611, k = 6), and ↑screen time (0.12; p = .242, k = 4).

CONCLUSIONS

Our findings support the short-term effects of MI on improving children's lifestyle behaviors. Additional investigations are needed to better sustain children's long-term behavioral changes.

Developing Motivational Interviewing Skills Among Undergraduate Nursing Students

The current study evaluated changes in undergraduate nursing students' knowledge and self-efficacy in motivational interviewing. Fourth-year undergraduate nursing students completed a hybrid, online curriculum. Changes in knowledge and self-efficacy were assessed using a pretest/posttest design. Repeated measures analysis of variance was used to determine differences between knowledge and self-efficacy mean scores. Of the 144 students who participated in the study, 88.2% were female, 96.5% were non-Hispanic/Latino, 88.9% were White, and mean age was 21.3 years. There were significant increases in knowledge and self-efficacy mean scores between pre-survey and post-survey 1 and 2. There were no differences between post-surveys 1 and 2 scores. A hybrid, online curriculum using asynchronous modules and synchronous simulation training can facilitate nursing students' learning experiences and enhance knowledge and self-efficacy about motivational interviewing.

The application and reporting of motivational interviewing in managing adolescent obesity: A scoping review and stakeholder consultation

Motivational interviewing (MI) is an evidence-based counseling approach that can help individuals make positive behavioral and cognitive changes for managing obesity. We conducted a scoping review to summarize evidence on fidelity and key elements of MI-based interventions for managing adolescent obesity and examine the reporting of these interventions. Ten electronic databases and gray literature were searched systematically and included literature from January 1983 to February 2022, and 26 studies were included. Data on MI features, delivery context, training, and fidelity to treatment were summarized. Fidelity was assessed using an assessment grid with five domains-theory, training, implementation, treatment receipt, and treatment enactment. The last step of the review involved stakeholder consultation with clinician-scientists and researchers with experience in MI and managing adolescent obesity. Thirteen stakeholders were interviewed about our review findings on MI and treatment fidelity. Our analyses revealed that MI-based interventions for managing adolescent obesity had "low treatment fidelity"; no studies had "high treatment fidelity" across all five domains. Fidelity strategies adhered to the most was theory, and treatment enactment was the lowest. Stakeholders mentioned that "low treatment fidelity" may be due to increased time to complete fidelity assessments and increased cost associated with treatment fidelity. These findings have implications for planning, implementing, and evaluating MI-based interventions for managing adolescent obesity.

Key Predictors of Primary Care Providers' Self-Efficacy in Caring for Children with Overweight or Obesity

OBJECTIVE

Self-efficacy is a crucial factor in enabling pediatric primary care providers (PCPs) to deliver recommended care to children with overweight and obesity. This study, conducted with a large, national sample of PCPs, aimed to identify key factors, which may contribute to PCP self-efficacy for obesity-related care, from a list of previously reported barriers and facilitators.

METHODS

A national random sample of American Academy of Pediatrics members was surveyed in 2017 (analytic n = 704). Factor analysis was used to identify self-efficacy variables from relevant indicators and assess fit. Multivariable linear regression analyses were conducted to identify key predictors of PCP self-efficacy from reported facilitators or barriers to care, including characteristics of the PCP, practice, community, and payment systems.

RESULTS

Two PCP self-efficacy variables were identified: health risk assessment and patient-centered counseling. Both were positively predicted by relevant training, the belief that pediatricians play an important role in obesity, and awareness of barriers to payment for dietitians or weight management programs. Both were negatively predicted by a perceived lack of available PCP time for counseling and inadequacy of available referral resources to assist with treatment. Additional predictors of counseling self-efficacy included PCP beliefs that they are paid for treatment (+) and that patients/families lack time for healthy behaviors (-). Electronic health record clinical decision supports or registries and patient social disadvantage were not predictive.

CONCLUSIONS

Results suggest multiple potential roles and strategies for local and national organizations seeking to facilitate improvements to PCP self-efficacy in caring for children with overweight and obesity.

Motivational interviewing to reduce anthropometrics among children: A meta-analysis, moderation analysis and Grading of Recommendations Assessment, Development and Evaluation assessment

BACKGROUND

Limited systematic reviews exist to evaluate the effects of motivational interviewing (MI) on children's anthropometric factors.

OBJECTIVE

This review examined the effects of MI interventions for children and/or parents on children's anthropometric factors and included moderation analyses and Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we searched Cochrane Library, PubMed, CINAHL, EMBASE, PsycINFO, Sociological Abstracts, SPORTDiscus, Education Resources Information Center, and Web of Science in December 2020. A two-step double screening approach was applied: (1) screening titles and abstracts, and (2) screening full-text articles obtained in step 1. At each step, discussion occurred until reaching consensus. The Cochrane risk-of-bias tool was used to evaluate risk of bias, and GRADE system was applied to assess overall quality of evidence. We performed meta-analyses using the Comprehensive Meta-Analysis software.

RESULTS

A total of 2209 records were found, and 45 eligible articles were retained. MI interventions had a pooled effect of -0.15 on body mass index (BMI; 95% confidence interval [CI]: -0.24 to -0.06), -0.36 on waist circumference (WC; 95% CI: -0.71 to -0.01) and -0.22 on percent body fat (95% CI: -0.41 to -0.03). Child baseline weight status and percent low-income families were identified as significant intervention moderators. According to the GRADE assessment, the quality of evidence on BMI percentile, BMI z-score and percent body fat was moderate, while quality on BMI and WC was low.

CONCLUSIONS

In conclusion, culturally appropriate clinic- or home-based MI interventions with adequate duration, dose and active parental involvement are promising in reducing anthropometrics among children.

Impact of a brief training on motivational interviewing and the 5A's approach on weight-related counseling practices of pediatricians

Background

Pediatric primary healthcare providers are well-positioned to provide healthy lifestyle and weight management related counseling but many lack training in evidence-based messages and methods.

Objectives

We assessed the impact of a brief, easy-to-access training for pediatric healthcare providers, (the Strong4Life Provider Training), designed to introduce/review current evidence-based messages and methods and improve healthy weight-related assessment and counseling practices.

Methods

Following their well-child visit, a convenience sample of children 12-17 years and parents of children 6-11 years (N = 121) of randomly selected Strong4Life trained (N = 15) and untrained (N = 15) pediatricians were administered a survey designed to assess the frequency, content, and patient satisfaction with weight management-related counseling provided. Results from parents and patients of trained pediatricians (N = 62) compared to those from parents and patients of untrained pediatricians (n = 59) were compared using chi-square tests. Generalized estimating equations were used to account for lack of independence among respondents from the same practice. P-values less than 0.05 were considered to be statistically significant.

Results

Parents/patients of trained pediatricians were more likely than those of an untrained pediatrician to report having been asked about child's consumption of fruit/vegetables, 57 (92%) versus 44 (75%), p = 0.04 and sugary drinks, 50 (81%) versus 29 (49%), p = 0.005, and their readiness for behavior change, 47 (76%) versus 29 (49%), p = 0.005, and to set a behavior change goal, 36 (59%) versus. 23 (40%), p = 0.005. Regardless of training status, physical activity, screen time, and weight status were assessed for most patients, and most were satisfied with the discussion. Few (21%) were asked about barriers to behavior change.

Implementation of physical activity on prescription for children with obesity in paediatric health care (IMPA): protocol for a feasibility and evaluation study using quantitative and qualitative methods

BACKGROUND

Physical inactivity is a main cause of childhood obesity which tracks into adulthood obesity, making it important to address early in life. Physical activity on prescription (PAP) is an evidence-based intervention that has shown good effect on physical activity levels in adults, but has not been evaluated in children with obesity. This project aims to evaluate the prerequisites, determinants, and feasibility of implementing PAP adapted to children with obesity and to explore children's, parents', and healthcare providers' experiences of PAP.

METHODS

In the first phase of the project, healthcare providers and managers from 26 paediatric clinics in Region Västra Götaland, Sweden, will be invited to participate in a web-based survey and a subset of this sample for a focus group study. Findings from these two data collections will form the basis for adaptation of PAP to the target group and context. In a second phase, this adapted PAP intervention will be evaluated in a clinical study in a sample of approximately 60 children with obesity (ISO-BMI > 30) between 6 and 12 years of age and one of their parents/legal guardians. Implementation process and clinical outcomes will be assessed pre- and post-intervention and at 8 and 12 months' follow-up. Implementation outcomes are the four core constructs of the Normalization Process Theory; coherence, cognitive participation, collective action, and reflexive monitoring; and appropriateness, acceptability, and feasibility of the PAP intervention. Additional implementation process outcomes are recruitment and attrition rates, intervention fidelity, dose, and adherence. Clinical outcomes are physical activity pattern, BMI, metabolic risk factors, health-related quality of life, sleep, and self-efficacy and motivation for physical activity. Lastly, we will explore the perspectives of children and parents in semi-structured interviews. Design and analysis of the included studies are guided by the Normalization Process Theory.

DISCUSSION

This project will provide new knowledge regarding the feasibility of PAP for children with obesity and about whether and how an evidence-based intervention can be fitted and adapted to new contexts and populations. The results may inform a larger scale trial and future implementation and may enhance the role of PAP in the management of obesity in paediatric health care in Sweden.

Sustainability of weight loss from a family-centered pediatric weight management program integrated in primary care

BACKGROUND

A 6-month pediatric weight loss program showed modest success, but the sustainability of this success after 12 months was unclear. The present study aims tomeasure the medium-term effectiveness of family-based weight management in pediatric primary care to reduce body weight in children living with obesity.

METHODS

In a retrospective cohort study, children ages 3 to 17 years with obesity in Kaiser Permanente Orange County, California, who enrolled in a weight management program between April 2014 and December 2018 (FB-WMG, n = 341) were compared to children referred but not enrolled (Ref-CG, n = 317) and controls matched by sex, age, zip code and BMI (Area-CG, n = 801). The relative distance from the median BMI-for-age at months 0, 6, and 12 were expressed as difference-in-differences (DID) using multivariable linear regressions with robust standard error.

RESULTS

The baseline BMI-for-age was 98.6 (SD 1.08) percentile in FB-WMG, 98.2 (SD 1.22) percentile in Ref-CG, and 98.6 (1.13 in Area-CG). FB-WMG had a median of 3 visits (P25 1 visit, P75 5 visits) in the first 6 months. Despite a more considerable decrease in the relative distance to the median BMI-for-age in FB-WMG children with 3+ visits after 6 months, the success obtained was not sustained at 12 months (DID FB-WMG vs Area-CG -0.34, 95% CI - 3.00 to 2.33%, FB-WMG vs Ref-CG -0.39, 95% CI - 3.14 to 2.35%). At 12 months, there was no statistical significant difference between the three groups (FB-WWG, Ref-CG, Area-CG).

CONCLUSIONS

The initial success in weight management was not sustained in the absence of continued support for healthy lifestyle changes. Based on current evidence, continued support is necessary to maintain and promote success beyond a brief 6 month intervention. Long-term pediatric weight management programs are needed to promote continuing progress.

Study Protocol of a Multicenter Randomized Controlled Trial to Tackle Obesity through a Mediterranean Diet vs. a Traditional Low-Fat Diet in Adolescents: The MED4Youth Study

Youth obesity is a strong predictor of adult obesity, which has well-known negative health consequences. Thus, addressing adult obesity requires tackling youth obesity. MED4Youth's main objective is to strengthen the link between the Mediterranean Diet (MD) and the health benefits against youth obesity and associated cardiovascular disease (CVD) risk factors, identifying positive effects exerted by an MD including sourdough bread and healthy products from the Mediterranean basis (chickpeas/hummus, nuts, and pomegranate juice). For this purpose, a multicenter randomized controlled trial in which an MD-based intervention will be compared to a traditional low-fat diet intervention will be carried out with 240 overweight and obese adolescents (13-17 years) from Spain, Portugal, and Italy. Both interventions will be combined with an educational web-application addressed to engage the adolescents through a learning-through-playing approach, using both educational materials and games. To assess the interventions, adherence to the MD, dietary records, physical activity, food frequency, sociodemographic, and quality of life questionnaires as well as classical anthropometric and biochemical parameters will be evaluated. Furthermore, an omics approach will be performed to elucidate whether the interventions can shape the gut microbiota and gut-derived metabolites to gain knowledge on the mechanisms through which the MD can exert its beneficial effects.

Influence of a One-Time Web-Based Provider Intervention on Patient-Reported Outcomes After the Well-Child Visit: A Feasibility Study

Purpose

Patient-centered care promotes positive health outcomes in pediatrics. We created a provider-focused intervention and implemented it in a pragmatic clustered randomized controlled trial to improve health-related quality of life (HRQOL) among pediatric patients.

Methods

A one-time (1-1.5-hour) webinar focusing on patient-centered care and motivational interviewing, using obesity screening as an example, was developed. Pediatric providers were recruited and randomized to either intervention (webinar) or control (usual care) arms. All well-child visits to these providers for a period of up to 5 months following webinar completion (or study enrollment for controls) were identified, and these family/patients were invited to complete a survey to assess HRQOL postvisit. Reported outcomes were compared between intervention and control participants using clustered t-tests, chi-squared tests and multiple linear regression models.

Results

We recruited 20 providers (10 intervention, 10 control) to the study; 469 parents/guardians and 235 eligible children seeing these providers completed the postvisit survey. Parents/guardians of 8-12-year-old children in the intervention group reported higher school functioning compared to controls (83.5 vs 75.8; P=0.023). There were no other differences in children's HRQOL between intervention and control groups.

Conclusions

A one-time, web-based provider intervention is feasible to implement in pediatrics. Modest evidence, requiring further study, indicates that instructing providers on patient-centered care in the well-child visit may improve aspects of pediatric HRQOL (ie, school functioning) compared to usual care. However, this was a brief intervention, with multiple outcomes tested and no evaluation of pre- and postintervention provider knowledge, thus additional study is needed.

Universal childhood obesity prevention in a rural community: Study design, methods and baseline participant characteristics of the NU-HOME randomized controlled trial

Childhood obesity is a major health concern in the United States (US) and those living in rural communities are at higher risk than their urban counterparts. Few prevention trials have engaged whole families of school-age children in community settings, and none to date have promoted family meals, family activity and healthful home environments in rural settings through a rigorous, randomized controlled trial (RCT). The New Ulm at HOME (NU-HOME) study recruited 114 parent/child dyads in a two-arm (intervention versus wait-list control) RCT to test the efficacy of a family meals-focused program aimed to prevent excess weight gain among 7-10 year-old children in rural Minnesota. The NU-HOME program was adapted from a previously tested program for urban families through a unique community collaboration. The program included 7 monthly in-person sessions for all family members. Parents also participated in 4 motivational goal-setting phone calls. The primary outcome measures were age- and sex-adjusted child body mass index (BMI) z-score, percent body fat, and incidence of overweight and obesity post-intervention. Secondary outcomes included quality of food and beverage availability in the home; family meals and snacks; children's dietary intake quality (e.g., Healthy Eating Index (HEI)-2015, fruits and vegetables, sugar-sweetened beverages, snacks); and children's screen time and weekly minutes of moderate-to-vigorous physical activity, total physical activity, and sedentary behavior. The NU-HOME RCT was a collaborative effort of academic and health system researchers, interventionists and community leaders that aimed to prevent childhood obesity in rural communities through engagement of the whole family in an interactive intervention.

Motivating Children and Adolescents in Obesity Treatment

Enhancing motivation is a crucial issue in pediatric obesity interventions, as behavioral changes related to food intake and physical exercise are difficult to carry out with an insufficient level of motivation. In the treatment setting, low motivation towards change may lead to early termination or inadequate treatment outcomes. This paper reviews widely-used models of motivation, including the transtheoretical model of change, self-determination theory, and motivational interviewing (MI). We introduce useful strategies based on each theoretical model to enhance motivation, such as an importance and confidence scale and a decisional balance technique. A review of recent MI interventions in children and adolescents is presented to discuss the efficacy of MI-based interventions and considerations for applying MI in pediatric obesity.

Motivational Interviewing for Overweight Children: A Systematic Review

CONTEXT

Motivational interviewing (MI) is a communication method to help facilitate adherence to health behaviors through a series of person-centered strategies. MI's evidence base supports its use as a potential intervention strategy at the parental decision-maker level to impact young children's lifestyle behaviors to address childhood obesity; however, clarity is needed on the literature.

OBJECTIVE

The purpose of this systematic review is to synthesize the literature examining the use of MI at the parental level to impact young children's weight status.

DATA SOURCES

A modified Cochrane method of systematic search and review was conducted in several databases (eg, PsycINFO, Academic Search Premier, Medline, Cumulative Index to Nursing and Allied Health Literature, Health Source: Nursing/Academic Edition, and SPORTDiscus).

STUDY SELECTION

Criteria for retention included randomized controlled trials and studies using varied settings, methods, interventionists, target behaviors, and outcomes.

DATA EXTRACTION

Extraction domains included study characteristics and risk of bias.

RESULTS

Of the 352 references initially identified, 7 studies were included in the review. In most studies, authors reported significant anthropometric changes as well as significant changes in nonanthropometric outcomes related to weight management compared to usual care.

LIMITATIONS

The heterogeneity of the included studies and lack of comparison with attention control groups may cloud generalizations. Studies not written in English were excluded, possibly biasing the results.

CONCLUSIONS

MI, compared to usual care, revealed positive effects for parent influence on young child anthropometric measures when applied. Future research should be focused on sample diversity, using attention control groups, using exercise physiologists for MI delivery, and reporting sex-specific results.

Reducing paediatric overweight and obesity through motivational interviewing: study protocol for a randomised controlled trial in the AAP PROS research network

INTRODUCTION

Primary care remains an underused venue for prevention and management of paediatric overweight and obesity. A prior trial demonstrated a significant impact of paediatrician/nurse practitioner (Ped/NP)-and registered dietitian (RD)-delivered motivational interviewing (MI) on child body mass index (BMI). The study described here will test the effectiveness of an enhanced version of this primary care-based MI counselling intervention on child BMI.

METHODS AND ANALYSIS

This cluster randomised effectiveness trial includes 24 Ped/NPs from 18 paediatric primary care practices that belong to the American Academy of Pediatrics (AAP) national Pediatric Research in Office Settings (PROS) practice-based research network. To date, practices have been randomised (nine to intervention and nine to usual care). Intervention Ped/NPs have been trained in MI, behavioural therapy, billing/coding for weight management and study procedures. Usual care Ped/NPs received training in billing/coding and study procedures only. Children 3- 11 years old with BMI >the 85th percentile were identified via electronic health records (EHRs). Parents from intervention practices have been recruited and enrolled. Over about 2 years, these parents are offered approximately 10 MI-based counselling sessions (about four in person sessions with their child's Ped/NP and up to six telephonic sessions with a trained RD). The primary outcome is change in child BMI (defined as per cent from median BMI for age and sex) over the study period. The primary comparison is between eligible children in intervention practices whose parents enrol in the study and all eligible children in usual care practices. Data sources will include EHRs, billing records, surveys and counselling call notes.

ETHICS AND DISSEMINATION

Institutional Review Board approval was obtained from the AAP. All Ped/NPs provided written informed consent, and intervention group parents provided consent and Health Insurance Portability and Accountability Act (HIPAA) authorisation. Findings will be disseminated through peer-reviewed publications, conference presentations and appropriate AAP channels.

Risk and Protective Factors Associated with Childhood Obesity in a Sample of Low-Income, Single Female, Parent/Guardian Households: Implications for Family Therapists

The United States is in the midst of a childhood obesity epidemic that disproportionately impacts underserved and diverse populations. In this study, in-depth qualitative interviews were conducted with 16 low-income, single, female, parent/guardians of an overweight or obese 3- to 8-year-old from socioeconomically disadvantaged backgrounds. Following the tenets of the thematic analysis approach, interviews focused on identifying risk and protective factors influencing parental and child health behaviors associated with child weight status. Results from the interviews are organized according to the Socioecological Framework to help identify risk and protective factors at various system levels. Findings from this investigation have relevance for family therapists as they can inform clinical and advocacy-focused interventions with disadvantaged families affected by childhood obesity.

Provider Practice and Perceptions of Pediatric Obesity in Appalachian Kentucky

OBJECTIVES

This study assessed providers' present practices and perceived needs in Appalachian Kentucky to identify the standard of care and implementation of expert recommendations for managing pediatric obesity.

METHODS

Questionnaire data were gathered from 28 providers at a pediatric obesity continuing medical education workshop in eastern Kentucky. We assessed current practices, perceived barriers to treatment, and needed resources for managing pediatric obesity.

RESULTS

Respondents reported mixed adherence to expert recommendations, with providers less frequently addressing family-reported barriers to change and assessing a family's readiness to change behaviors related to pediatric obesity. Respondents also reported service barriers related to patient motivation, lack of time with patients, and a lack of referral options. Finally, providers reported needing multiple community resources to better address pediatric obesity, including improved physical education programs, access to community recreation centers, additional referral resources for multidisciplinary care, and additional training in motivational techniques.

CONCLUSIONS

There remains a significant need for education and guidance regarding the implementation of expert recommendations for addressing pediatric obesity in Appalachian Kentucky. Providers reported needing multiple community resources, including improved physical education programs, access to community recreation centers, additional referral resources for multidisciplinary care, and additional training in motivational techniques. We discuss the implications for disseminating and implementing expert recommendations in rural eastern Kentucky, with an emphasis on the roles of behavioral health experts.

Behavioral Interventions for Weight Management in Overweight and Obese Adolescents: A Comparison Between a Motivation-based Educational Program and Conventional Dietary Counseling

OBJECTIVES

This study aimed to compare the effects of a three-month motivation-based educational program and conventional dietary counseling on body composition and relevant outcomes among overweight and Obese adolescents.

METHODS

A total of 115 overweight and obese adolescents (46% boys) were randomly assigned to either a motivation-based program or a conventional dietary counseling. The assessments were conducted at baseline and 3, 6, and 12 months after intervention.

RESULTS

Mean age and body mass index (BMI) Z-score were 14.5 ± 1.2 and 2.42 ± 0.62, respectively. Considering time trend analysis, the two groups achieved significant improvements in BMI Z-score, wrist and waist circumferences, body composition indices, and HRQoL total scores after a one-year follow-up. Wrist circumference and the HRQoL reported by parents revealed significant differences between the study groups in favor of the motivation-based program.

CONCLUSIONS

Although both programs could improve anthropometric indices and HRQoL over time, the motivation-based program was more effective in reducing adolescents' wrist circumference and improving HRQoL, as the parents reported.

The Healthy Homes/Healthy Kids 5-10 Obesity Prevention Trial: 12 and 24-month outcomes

BACKGROUND

Pediatric primary care is an important setting for addressing obesity prevention.

OBJECTIVE

The Healthy Homes/Healthy Kids 5-10 randomized controlled trial evaluated the efficacy of an obesity prevention intervention integrating pediatric primary care provider counseling and parent-targeted phone coaching.

METHODS

Children aged 5 to 10 years with a BMI between the 70th and 95th percentile and their parents were recruited from pediatric primary care clinics. Participants received well-child visit provider counseling about obesity and safety/injury prevention and were then randomized to a 14-session phone-based obesity prevention (OP; n = 212) or safety and injury prevention contact control (CC; n = 209) intervention. The primary outcome was 12 and 24-month child BMI percentile.

RESULTS

There was no overall significant treatment effect on child BMI percentile. Caloric intake was significantly lower among OP compared with CC participants at 12 months (P < .005). In planned subgroup analyses, OP condition girls had significantly lower BMI percentile (P < .05) and BMI z-score (P < .02) at 12 and 24 months relative to CC girls and were less likely to be overweight (38.0% vs 53.0%, P < .01) or (obese 3.4% vs 8.8%, P < .10) at follow-up.

CONCLUSIONS AND RELEVANCE

An obesity prevention intervention integrating brief provider counseling and parent-targeted phone counseling did not impact 12 and 24-month BMI status overall but did have a significant impact on BMI in girls.

Clinical Considerations Regarding the Use of Obesity Pharmacotherapy in Adolescents with Obesity

A growing number of youth suffer from obesity and in particular severe obesity for which intensive lifestyle intervention does not adequately reduce excess adiposity. A treatment gap exists wherein effective treatment options for an adolescent with severe obesity include intensive lifestyle modification or metabolic and bariatric surgery while the application of obesity pharmacotherapy remains largely underutilized. These youth often present with numerous obesity-related comorbid diseases, including hypertension, dyslipidemia, prediabetes/type 2 diabetes, obstructive sleep apnea, nonalcoholic fatty liver disease, musculoskeletal problems, and psychosocial issues such as depression, anxiety, and social stigmatization. Current pediatric obesity treatment algorithms for pediatric primary care providers focus primarily on intensive lifestyle intervention with escalation of treatment intensity through four stages of intervention. Although a recent surge in the number of Food and Drug Administration-approved medications for obesity treatment has emerged in adults, pharmacotherapy options for youth remain limited. Recognizing treatment and knowledge gaps related to pharmacological agents and the urgent need for more effective treatment strategies in this population, discussed here are the efficacy, safety, and clinical application of obesity pharmacotherapy in youth with obesity based on current literature. Legal ramifications, informed consent regulations, and appropriate off-label use of these medications in pediatrics are included, focusing on prescribing practices and prescriber limits.

Impact of an American board of pediatrics maintenance of certification (MOC) on weight-related counseling at well-child check-ups

OBJECTIVE

The Healthy Weight Counseling Maintenance of Certification (MOC) program integrates pediatrician training and clinic changes to promote use of evidence-based, diet and physical activity (PA) health messages and counseling strategies. This interrupted time series study assessed the impact of this MOC program on provision of weight-related counseling.

METHODS

We randomly selected 10-15 well-child visit charts at three time points before and three time points after 102 Georgia pediatricians began the MOC in 2012-2015. Linear binomial regression compared the frequency of behavior-change goal setting and health messaging documentation (fruit/vegetable consumption, sugar-sweetened beverage consumption, out-of-home food consumption, PA, and screen time) before and after MOC participation.

RESULTS

At baseline, pediatricians documented behavior-change goals with 44% of patients, with an additional 49% of patients having documented goals after their pediatrician started the MOC (99.5% confidence interval [CI]: 21-77%). Similarly, absolute increases in the proportion of patients with documentation for sugar-sweetened beverage consumption (adjusted prevalence difference [aPD]: 37%; 99.5% CI: 13-62%) and out-of-home eating were observed (aPD: 38%; 99.5% CI: 12-64%).

CONCLUSION

The Healthy Weight Counseling MOC is associated with increased and sustained use of evidence-based health messages and counseling strategies.

PRACTICE IMPLICATIONS

Continuing education and facilitation of system changes help improve physicians' weight-related counseling.

"C.H.A.M.P. Families": Description and Theoretical Foundations of a Paediatric Overweight and Obesity Intervention Targeting Parents-A Single-Centre Non-Randomised Feasibility Study

Childhood obesity represents a significant global health challenge, and treatment interventions are needed. The purpose of this paper is to describe the components and theoretical model that was used in the development and implementation of a unique parent-focussed paediatric overweight/obesity intervention. C.H.A.M.P. Families was a single-centre, prospective intervention offered to parents of children aged between 6–14 years with a body mass index (BMI) ≥85th percentile for age and sex. The intervention included: (1) eight group-based (parent-only) education sessions over 13-weeks; (2) eight home-based activities; and (3) two group-based (family) follow-up support sessions. The first section of the manuscript contains a detailed description of each intervention component, as well as an overview of ongoing feasibility analyses. The theoretical portion details the use of evidence-based group dynamics principles and motivational interviewing techniques within the context of a broader social cognitive theory foundation. This paper provides researchers with practical examples of how theoretical constructs and evidence-based strategies can be applied in the development and implementation of parent-focussed paediatric obesity interventions. Given the need for transparent reporting of intervention designs and theoretical foundations, this paper also adds to the areas of implementation science and knowledge translation research.

Percent Body Fat Measurement in the Medical Management of Children with Obesity

Sustaining weight loss can be challenging, as physiological responses to weight loss, including metabolic and hormonal adaptations and decreased energy expenditure, promote weight regain. Paired with sustained dietary changes, physical activity can promote weight maintenance after successful weight loss, as physical activity can help maintain fat-free mass. We present several illustrative cases to highlight the potential use of body composition measurement using a bioelectrical impedance analysis (BIA) scale to augment obesity management counseling in a tertiary care pediatric weight-management clinic. BIA does require some interpretation, as it can be affected by hydration status and time of day, as well as patient age, sex, and body mass index. Nonetheless, BIA can be a helpful aid to obesity counseling. More research is needed to better understand how to use change in percent body fat over time as a motivational tool for management of children with obesity. [Pediatr Ann. 2018;47(12):e487-e493.].

Pragmatic Strategies for Shared Decision-making

Shared decision-making (SDM) is a process that brings together clinical expertise and families' values to arrive at a treatment choice. The process is especially useful for situations with >1 reasonable option, a condition of equipoise. However, for pediatricians who want to adhere to SDM best practices, there is limited practical guidance regarding how to communicate with parents and patients. With the following text, we describe pragmatic strategies to support SDM around both high-stakes decisions in the acute setting as well as in the ongoing management of chronic conditions in settings such as primary care.

Does motivational interviewing improve the weight management process in adolescents? Protocol for a systematic review and meta-analysis

BACKGROUND

Data on the effects of motivational interviewing (MI) on modifying unhealthy lifestyles and promoting weight status during childhood is controversial. Adolescents are more prone to assume higher personal responsibilities for behavioral changes. This study aims to investigate whether MI will improve weight management process in adolescents.

METHODS/DESIGN

A systematic review will be conducted on clinical trials, assessing the effect of MI on weight management processes in adolescents, aged 10 to 19 years. The primary objective is to assess the efficacy of MI in controlling weight-related measures in overweight and obese adolescents. Secondary objectives are assessing the efficacy of MI on obesity-related behaviors and cognitive abilities considering heterogeneity in outcomes of primary studies in different MI settings. Main data sources include MEDLINE/PubMed, Scopus, Embase, Web of Science, Cochrane, and PsycINFO from 1980 to May, 2018, with no language restrictions. Study selection, data extraction, and risk of bias assessment will be performed by two independent reviewers. A meta-analysis will be conducted on relevant outcomes. Data will be analyzed for outcome of interest using the 95% confidence interval (CI) of an estimate for dichotomous outcomes and mean differences (MDs) for continious outcomes. Cochrane's Q statistic and the I2 statistic will be performed to evaluate the heterogeneity. Subgroup analysis and suitable analytical strategies will be conducted to identify the potential sources of heterogeneity. As we expect a high heterogeneity in our included studies, pooled risk ratios (RRs) and 95% CI will be calculated to estimate the overall effect sizes, using meta-regression models or finite mixture modeling through conducting random effect methods. GRADE system will be used to evaluate the certainty of evidence. We will also use subgroup analysis and the GRADE system to investigate the effect of methodological quality of primary studies on results of meta-analysis. Funnel plots and egger and beggs test and plot will be implemented to assess publication bias.

DISCUSSION

The results of this systematic review will provide more insights regarding the effect of MI on weight management in adolescents and will be useful for future research and health promotion programs in this age group.

Childhood obesity

Childhood obesity has assumed epidemic proportions and it is currently one of the most prevalent public health problems. The pathophysiology of excess weight gain is complex with interactions between genetic factors, environment and biological factors. In this review, we highlight the epidemiology of childhood obesity and discuss clinical evaluation of a child with obesity. A staged approach to treatment is detailed. We discuss the role of lifestyle modifications, pharmacotherapy and bariatric surgery as treatment strategies.

Obesity Prevention and Treatment in Primary Care

Despite extensive public health and clinical interventions, obesity rates remain high, and evidence-based preventive strategies are elusive. Many consensus guidelines suggest that providers should screen all children after age 2 years for obesity by measuring height and weight, calculating body mass index (BMI), and sensitively communicating weight status in the context of health to the family at each visit. However, preventive counseling should begin in infancy and focus on healthy feeding, activity, and family lifestyle behaviors. For children with overweight or obesity, the American Academy of Pediatrics outlines 4 stages of treatment: 1) Primary care providers should offer "prevention plus," the use of motivational interviewing to achieve healthy lifestyle modifications in family behaviors or environments; 2) children requiring the next level of obesity treatment, structured weight management, need additional support beyond the primary care provider (such as a dietitian, physical therapist, or mental health counselor) and more structured goal setting with the team, including providers adept at weight management counseling; 3) children with severe obesity and motivated families may benefit from referral to a comprehensive multidisciplinary intervention, such as an obesity treatment clinic; and 4) tertiary care interventions are provided in a multidisciplinary pediatric obesity treatment clinic with standard clinical protocols for evaluation of interventions, including medications and surgery. Although it is certainly a challenge for providers to fit in all the desired prevention and treatment counseling during preventive health visits, by beginning to provide anticipatory guidance at birth, providers can respond to parents' questions, add to parents' knowledge base, and partner with parents and children and adolescents to help them grow up healthy. This is especially important in an increasingly toxic food environment with numerous incentives and messages to eat unhealthfully, barriers to appropriate physical activity, and concomitant stigma about obesity. Focusing on key nutrition and physical activity habits and establishing these healthy behaviors at an early age will allow children to develop a healthy growth trajectory. However, much more work is needed to determine the best evidence-based practices for providers to counsel families on improving target behaviors, environmental modifications, and parenting skills and to decrease abundant disparities in obesity prevalence and treatment.

Health Care Provider's Role in Obesity Prevention and Healthy Development of Young American Indian Children

INTRODUCTION

Health care providers (HCPs) serving American Indian (AI) populations are critical stakeholders in promoting healthy weight-related behaviors of young AI children. The purpose of this study is to develop an understanding of how HCP perceive their role in the healthy development of young AI children, and how they envision working with early care and education teachers and parents to enhance children's health.

METHOD

Twenty HCP that serve young AI children in Oklahoma participated in individual interviews. Thematic analysis was conducted on coded transcripts and three main themes, each with two to four subthemes were identified.

RESULTS

HCP had limited contact with teachers, felt family health was equal or more important than child health, and parental empowerment and gradual change was essential for success.

CONCLUSION

Creating ways to involve HCP, early care and education teachers, and parents together in multilevel and multisector interventions has the potential to improve the health of young AI children.

Family Functioning and Childhood Obesity Treatment: A Family Systems Theory-Informed Approach

Childhood obesity recommendations advise providers to use family-based care for the treatment of youth and adolescent obesity. Family-based care, defined as the inclusion of a caregiver and a youth, is commonly conducted through behavioral interventions that target the dietary and physical activity behaviors of the attending parent-youth dyads. However, focusing on behaviors isolated to the parent and youth neglects the rest of the family members, and the larger rules, routines, communication, and dynamics in the family. Family-based interventions grounded in family systems theory (FST) target family dynamics to influence weight-related behaviors through higher-level changes in the family. The utility of using FST in childhood obesity treatment has not been extensively conceptualized or applied. Few outcome studies have reported on variables representative of FST, and even fewer FST interventions have been conducted. Because of the lack of detail on the application of FST to childhood obesity treatment, providers are left with little clarity on how to use FST in clinical encounters. We provide the background and evidence for use of FST, detail how families organize around weight-related behaviors that contribute to obesity, and on the basis of their organization, what type of treatment might be beneficial, FST-informed or family-based behavioral interventions. Finally, a suggested family-based clinical algorithm is provided detailing the use of FST through assessment, intervention, and follow-up that can be refined over time by providers and researchers committed to viewing obesity in the context of the family and family dynamics.

A novel peer-support intervention using motivational interviewing for breastfeeding maintenance: a UK feasibility study

BACKGROUND

In total, 81% of women in the UK start breastfeeding, but fewer than half continue beyond 6 weeks. Peer support in the early postnatal period may encourage women to breastfeed for longer.

OBJECTIVE

To develop a breastfeeding peer-support intervention based on motivational interviewing (MI) for breastfeeding maintenance and to test the feasibility of delivering it to mothers in areas with high levels of social deprivation.

DESIGN

Intervention development and a non-randomised multisite feasibility study.

SETTING

Community maternity services in three areas with high levels of social deprivation and low breastfeeding initiation rates in England and Wales.

PARTICIPANTS

Pregnant women considering breastfeeding. Women who did not plan to breastfeed, who had a clinical reason that precluded breastfeeding continuation or who were unable to consent were excluded.

INTERVENTION

The intervention Mam-Kind was informed by a survey of infant feeding co-ordinators, rapid literature review, focus groups with service users and peer supporters and interviews with health-care professionals and a Stakeholder Advisory Group. It consisted of face-to-face contact at 48 hours after birth and proactive one-to-one peer support from the Mam-Kind buddy for 2 weeks, followed by mother-led contact for a further 2-6 weeks.

MAIN OUTCOME MEASURES

Recruitment and retention of Mam-Kind buddies, uptake of Mam-Kind by participants, feasibility of delivering Mam-Kind as specified and of data collection methods, and acceptability of Mam-Kind to mothers, buddies and health-care professionals.

RESULTS

Nine buddies were recruited to deliver Mam-Kind to 70 participants (61% of eligible women who expressed an interest in taking part in the study). Participants were aged between 19 and 41 years and 94% of participants were white. Intervention uptake was 75% and did not vary according to age or parity. Most contacts (79%) were initiated by the buddy, demonstrating the intended proactive nature of the intervention and 73% (n = 51) of participants received a contact within 48 hours. Follow-up data were available for 78% of participants at 10 days and 64% at 8 weeks. Data collection methods were judged feasible and acceptable. Data completeness was > 80% for almost all variables. Interviews with participants, buddies and health service professionals showed that the intervention was acceptable. Buddies delivered the intervention content with fidelity (93% of intervention objectives were met), and, in some cases, developed certain MI skills to a competency level. However, they reported difficulties in changing from an information-giving role to a collaborative approach. These findings were used to refine the training and intervention specification to emphasise the focus of the intervention on providing mother-centric support. Health-care professionals were satisfied that the intervention could be integrated with existing services.

CONCLUSIONS

The Mam-Kind intervention was acceptable and feasible to deliver within NHS maternity services and should be tested for effectiveness in a multicentre randomised controlled trial. The feasibility study highlighted the need to strengthen strategies for birth notification and retention of participants, and provided some insights on how this could be achieved in a full trial.

LIMITATIONS

The response rate to the survey of infant feeding co-ordinators was low (19.5%). In addition, the women who were recruited may not be representative of the study sites.

Realist-informed review of motivational interviewing for adolescent health behaviors

BACKGROUND

Clinical research investigating effective intervention strategies for adolescents to improve health behaviors has shifted to the application of motivational interviewing (MI). Evidence indicates that MI is an effective intervention for improving health behaviors as related to diet, exercise, and diabetes among adolescents. However, there is a lack of understanding about the mechanisms through which MI works and the contextual factors impacting MI effectiveness. The purpose of this review was to understand how, for whom, and under what circumstances MI works for adolescent health behavior change, which will inform future implementation of this intervention. To provide this in-depth understanding, a realist-informed systematic review was conducted in order to synthesize the evidence on the use of MI for health behaviors. Self-determination theory (SDT) was chosen as the candidate theory for testing in the present review.

METHODS

Databases including PsycINFO, Healthstar, Cochrane, and PubMed were searched for articles published until March 2017. The search strategy included studies that examined or reviewed the effectiveness or efficacy of MI to change health behaviors among adolescent populations. The search identified 185 abstracts, of which 28 were included in the review. The literature was synthesized qualitatively (immersion/crystallization) and tested SDT as the candidate theory.

RESULTS

Based on SDT, three mechanisms were found within reviewed studies, including competence, relatedness, and autonomy. The following contexts were found to impact mechanisms: school setting, clinician MI proficiency, parental involvement, and peer involvement.

CONCLUSIONS

This realist-informed systematic review provides advances in understanding the mechanisms involved in MI for adolescent health behavior change. Additionally, it provides important practical information as to which contexts create the conditions for these mechanisms to occur, leading to health behavior change. The results can inform future MI interventions for adolescent health behavior change. Future research should continue to test this realist theory and also examine mechanism variables not extensively documented in order to improve our understanding of MI in this population.

Case study: Behavior changes in the family-focused obesity prevention HOME Plus program

OBJECTIVE

The purpose of this case study is to describe two successful HOME Plus participants and highlight how an intervention with individual and group components can help families make lifestyle changes that result in improvements in child weight status.

DESIGN

One hundred and sixty families participated in the HOME Plus study, and were randomized to either a control or intervention group.

SAMPLE

Two successful HOME Plus participants were chosen because of their healthful changes in weight status and behavior and high engagement in the program.

MEASUREMENTS

Data were collected at baseline and postintervention, 1 year later. Data included height, weight, home food inventory, dietary recalls, and psychosocial surveys.

INTERVENTION

Families in the intervention group participated in cooking and nutrition education sessions, goal-setting activities, and motivational interviewing telephone calls to promote behavioral goals associated with meal planning, family meal frequency, and healthfulness of meals and snacks.

RESULTS

Analysis of the families' behaviors showed that Oliver (fictitious name) experienced changes in nutritional knowledge and cooking skill development while Sophia's (fictitious name) changes were associated with healthful food availability and increased family meal frequency.

CONCLUSION

These cases show that offering a multicomponent, family-focused program allows participants to select behavior strategies to fit their unique family needs.

A Healthy School Start Plus for prevention of childhood overweight and obesity in disadvantaged areas through parental support in the school setting - study protocol for a parallel group cluster randomised trial

Background

Systematic reviews conclude that interventions to prevent overweight and obesity in children obtain stronger effects when parents are involved. Parenting practices and parent-child interactions shape children’s health-related behaviours. The Healthy School Start Plus intervention aims to promote healthy dietary habits and physical activity and prevent obesity in children through parental support in disadvantaged areas with increased health needs, delivered by teachers and school nurses. This protocol describes the design, outcome and process evaluation of the study.

Methods

Effectiveness of the intervention is compared to standard care within school health services. The 6-month programme, based on Social Cognitive Theory, consists of four components: 1) Health information to parents regarding the child; 2) Motivational Interviewing with the parents by the school nurse concerning the child; 3) classroom activities for the children by teachers; and 4) a web-based self-test of type-2 diabetes risk by parents. Effects will be studied in a cluster randomised trial including 17 schools and 352 six-year old children. The primary outcome is dietary intake of indicator foods, and secondary outcomes are physical activity, sedentary behaviour and BMI. Outcomes will be measured at baseline, at 6 months directly after the intervention, and at follow-up 18 months post baseline. Statistical analysis will be by mixed-effect regression analysis according to intention to treat and per protocol. Mediation analysis will be performed with parental self-efficacy and parenting practices. Quantitative and qualitative methods will be used to study implementation in terms of dose, fidelity, feasibility and acceptability. The hypothesis is that the programme will be more effective than standard care and feasible to perform in the school context.

Discussion

The programme is in line with the cumulated evidence regarding the prevention of childhood obesity: That schools should be a focal point of prevention efforts, interventions should involve multiple components, and include the home environment. If effective, it will fill a knowledge gap concerning evidence-based health promotion practice within school health services to prevent obesity, and in the long term reduce social inequalities in health.

Trial registration

The trial was retrospectively registered on January 4, 2018 and available online at ClinicalTrials.gov: No. NCT03390725.

Physical activity and family-based obesity treatment: a review of expert recommendations on physical activity in youth

Targeting physical inactivity in children is pertinent to aiding in the decrease of childhood obesity rates. Only 33% of adolescents are obtaining the recommended goal of at least 60 min of physical activity per day. The objectives of this review are to summarize professional recommendations for physical activity and exercise in children and adolescents, and identify family-centred strategies that can be implemented by weight management clinicians. Clinically oriented recommendations and policy statements from professional organizations were identified through literature and internet searches, summarized using rubrics of aerobic, muscle strengthening and bone strengthening exercise, then examined for details on family-based focus, inclusion of child developmental stage and age, and application to the prevention and treatment of obesity. Current recommendations give guidelines for the amount of physical activity that children should acquire and how many days a week activities should occur. However, available guidelines need an improved approach to addressing the role of the parents and caregivers in targeting physical activity and weight management in youth. Efforts must be taken in order to make sure that the types of physical activity offered are both suitable and enjoyable. Sports, games, free play and other age appropriate activities are adequate ways to increase moderate to vigorous physical activity in children. Differentiating physical activities types in accordance with developmental stage, level of enjoyment, and family characteristics is needed to establish sustainable habits. One paediatric obesity program has developed approaches to teaching families fun and engaging ways to be active together.

Perceived Parental Barriers to and Strategies for Supporting Physical Activity and Healthy Eating among Head Start Children

Despite the need for parents to support their children's healthy behaviors, knowledge of factors preventing parents from doing so is still rudimentary. This study primarily aimed to explore perceived parental barriers to and strategies for supporting physical activity and healthy eating among Head Start children. A semi-structured interview format was used with four focus groups conducted at two urban Head Start centers in the Midwestern U.S. A qualitative content analysis of audio-recorded sessions was facilitated using ATLAS.ti7. A convenience sample of 32 parents (Mage = 34.97 years) participated. Over half were female (78.1 %), African Americans (65.6 %), and single (65.6 %). About 61.3 % reported an annual family income <$20,000, and 43.8 % were unemployed. Three themes reflected the barriers: (1) intrapersonal (child): short attention span and limited eating preferences; (2) interpersonal (parent): lack of time and cooking skills and a tight family budget; and (3) environmental: inaccessible programs, lack of age-appropriate education, electronic media use, and unsafe environment. Parents across all groups expressed high interest in enrolling in a program with their children. Recommendations included: parents' support team; family outings at parks; taking a walk or enrolling in a class with children; and planting a garden. Many parents showed their preference for face-to-face meetings and a support group, but repulsion of counseling. To promote parental support in future interventions with Head Start children, their perceived intrapersonal, interpersonal, and environmental barriers should be considered as intervention targets. Involving parents through a support group and face-to-face meetings is recommended.

Can a Pediatrician Effectively Treat a 9-Year-Old Obese Girl?

Maria is a 9-year-old Latina girl who was followed up by her pediatrician since birth with normal developmental milestones, good school achievement, and without significant medical problems. She was not in the pediatric office for the past 3 years. At the age of 9 years, she presented for a health supervision visit. Her pediatrician looked at her growth chart-90 pounds (95th percentile) and height 52 inches (50th percentile)-that confirmed a clinical impression of obesity on physical examination. Her body mass index was 23.4 (>95th percentile for age).During 10 years in primary care pediatric practice, the pediatrician typically prescribed a management plan for obese school-aged and adolescent patients that started with parent and child education about potential health problems associated with obesity followed by a recommendation to decrease the caloric intake and encourage active exercise each day. She then arranged for follow-up visits to monitor weight and adherence to the management plan. However, a moment of self-refection suggested that most of her patients did not follow her advice in a sustained way. Obesity persisted in most cases. The pediatrician wondered if there was an alternative-better yet, evidence-based-approach to pediatric obesity that might provide a better outcome.

Chronic Headaches After a Concussion in an Obese 16-Year-Old Girl

Jennifer is a 16-year-old Latina girl who is new to your practice. During her first well visit, she mentions that she has had daily headaches for 2 years. They began after sustaining a concussion in a car accident. Typically, her headaches are bilateral and "squeezing"; they occur in the afternoons and last for a few hours. Her concussion also resulted in depressed mood, which has improved over time.When you ask if her headaches have changed recently, she says that they have been worse for the last few days. The quality and severity are unchanged; however, they now occur first thing in the morning, are worse when supine, and no longer remit. In the last 2 days, she has developed new-onset blurry vision, nausea, dizziness, photophobia, and sonophobia. Although she previously experienced sadness with her concussion, she now feels irritable. She has never used tobacco, alcohol, or drugs, and she takes no medications.On examination, her body mass index is above the 99th percentile. You note mild papilledema bilaterally. She has no focal neurological deficits. The remainder of her examination is normal.You send her to an emergency department. Her head computed tomography is normal. A lumbar puncture demonstrates an opening pressure of 32 cm H2O; she feels relief after the procedure. She is admitted with a diagnosis of benign intracranial hypertension and is started on acetazolamide. What is the differential diagnosis of chronic headaches in an obese adolescent? How should a busy community pediatrician manage Jennifer acutely? What follow-up care should Jennifer receive?

Disparities in Body Mass Index Trajectories From Adolescence to Early Adulthood for Sexual Minority Women

PURPOSE

We aimed to estimate group-based trajectories of body mass index (BMI) in a longitudinal cohort of young women and determine the association between sexual identity and BMI trajectory group, adjusting for obesity risk factors.

METHODS

We analyzed data from females in waves I-IV of the National Longitudinal Study of Adolescent to Adult Health. Sexual identity was categorized as heterosexual, mostly heterosexual, bisexual, or lesbian (homosexual/mostly homosexual). We conducted group-based trajectory modeling of BMI with a censored normal distribution and a cubic relationship with age to identify three BMI trajectory groups. Multinomial logit regressions predicted the risk of trajectory membership associated with sexual identity, adjusting for background characteristics.

RESULTS

At wave I, the mean (n = 7,801) age was 15.9 years (95% confidence interval: 15.6-16.1). Subjects were 16.3% African-American; and 80.0% heterosexual, 15.9% mostly heterosexual, 2.5% bisexual, and 1.7% lesbian. Group-based trajectory modeling identified three BMI trajectory groups characterized as (1) minimal obesity (62.2%), (2) developing obesity (29.9%), and (3) progressive obesity (8.0%). In multinomial logit regressions adjusted for age, race, parental obesity and education, sexual abuse, household income, screen time, depressive symptoms, and rural residence, lesbian women had a nearly two-fold higher relative risk of being in the developing obesity trajectory group (relative risk ratio = 1.91, 95% confidence interval: 1.10-3.32) relative to the minimal obesity group, compared with heterosexual women.

CONCLUSIONS

Lesbian women were at increased risk of membership in the developing obesity trajectory group compared with heterosexual women. Adjusting for obesity risk factors had minimal impact on the point estimates for this association.

Counselor competence for telephone Motivation Interviewing addressing lifestyle change among Dutch older adults

Counselor competence in telephone Motivation Interviewing (MI) to change lifestyle behaviors in a primary care population was assessed using the Motivational Interviewing Treatment Integrity (MITI) rating system. Counselor behavior was evaluated by trained raters. Twenty minutes of a random sample of 336 MI sessions were coded representing 232 counselees. Ninety-four sessions (28%) were double coded to assess inter-rater agreement. The MI fidelity was examined by comparing the MI fidelity scores direction, empathy, spirit, % open questions, % complex reflections, reflections-to-questions ratio, % MI-adherent responses with the matching beginner proficiency MITI threshold. The inter-rater agreements for the MI fidelity summary scores were good (spirit, reflections-to-questions ratio), fair (empathy, % open questions, % MI-adherent responses) or poor (direction, % complex reflection). The MI fidelity scores for direction, empathy, spirit and the percentage of complex reflections exceeded the MITI threshold, but lower scores were found for the percentage of open questions, the reflections-to-questions ratio and the percentage of MI-adherent responses. In conclusion, evidence that MI was implemented was revealed. However, the inter-rater agreements scores and some fidelity scores leave room for improvement indicating that raters and counselors may need more ongoing training and feedback to achieve and maintain adequate competence. These findings apply to more complex skills (as rating complex reflections) in particular.
