Ending prematurely a weight loss programme: the impact of child and family characteristics

Motivators and Barriers to Seeking Metabolic and Bariatric Surgery Among Adolescents: A Qualitative Study

Background

The prevalence of severe obesity among adolescents has increased the use of metabolic and bariatric surgery (MBS) as a therapeutic option. Understanding factors influencing adolescent MBS choice and the support needed to undergo MBS is crucial for improving health outcomes. This study examines the motivations and support needs of a diverse sample of adolescents seeking MBS via the patient voice.

Methods

Adolescents (n = 14) at a weight loss surgery clinic in a large academic healthcare system participated in qualitative interviews. Of the participants, 10 were female, 6 were non-Hispanic Black, 3 were non-Hispanic White, and 5 were Hispanic. Interviews were recorded, transcribed, and thematically analyzed.

Results

Three themes emerged: Intrinsic motivators, extrinsic motivators, and barriers. Intrinsic motivators include personal physical and mental health goals. Extrinsic motivators involved family and medical team support, which provided encouragement, validation, and perceived confidence for lifestyle changes. Additionally, observing family members who previously completed MBS was a significant extrinsic motivator. Concerns included fear of dying/complications from MBS, and possible weight regain post-MBS.

Conclusion

Adolescent MBS programs should enhance intrinsic motivation for behavior changes. Findings highlight opportunities for bolstering support pre- and post-MBS and addressing MBS-related anxieties related to long-term weight management.

Relationships examined: Parent and child readiness to change and sociodemographic characteristics in family based weight loss treatment

BACKGROUND

Family based treatment is an effective, multipronged approach to address obesity as it plagues families.

OBJECTIVE

To investigate the relationships among sociodemographic characteristics (e.g., education and income), body mass index (BMI) and race/ethnicity with readiness to change for parents enrolled in the Primary care pediatrics, Learning, Activity and Nutrition (PLAN) study.

METHODS

Multivariate linear regressions tested two hypotheses: (1) White parents will have higher levels of baseline readiness to change, when compared to Black parents; (2) parents with higher income and education will have higher levels of readiness to change at baseline.

RESULTS

A positive relationship exists between baseline parent BMI and readiness to change (Pearson correlation, 0.09, p < 0.05); statistically significant relationships exist between parent education level (-0.14, p < 0.05), income (0.04, p < 0.05) and readiness to change. Additionally, a statistically significant relationship exists, with both White (β, -0.10, p < 0.05), and Other, non-Hispanic (-0.10, p < 0.05) parents exhibiting lower readiness to change than Black, non-Hispanic parents. Child data did not indicate significant relationships between race/ethnicity and readiness to change.

CONCLUSIONS

Results demonstrate that investigators should consider sociodemographic characteristic factors and different levels of readiness to change in participants enrolling in obesity interventions.

Self-control training supplementing inpatient multidisciplinary obesity treatment in children and adolescents

Research points to self-control as a possible mechanism for facilitating health behaviour and weight loss. The dual pathway model underpins the role of strong bottom-up reactivity towards food and weak top-down executive functions in obesity. Despite flourishing lab studies on attention bias modification or inhibition trainings, relatively few focused on training both processes to improve self-control in children and adolescents in inpatient multidisciplinary obesity treatment (MOT). Being part of the WELCOME project, this study investigated the effectiveness of Brain Fitness training (using the Dot Probe and Go/No-Go) as an adjunct to inpatient MOT in 131 Belgian children and adolescents. Changes in self-control (performance-based inhibitory control and attention bias as well as self-reported eating behaviour) in the experimental group were compared to sham training. Multiple Imputation was used to handle missing data. Inhibitory control and external eating improved over time (pre/post/follow-up), but we found no evidence for a significant interaction between time and condition. Future research should pay more attention to the role of individual variability in baseline self-control, sham training, and ecological validity of self-control training to improve real-life health behaviour and treatment perspectives for children and adolescents with weight problems.

Factors predicting parent engagement in a family-based childhood obesity prevention and control program

BACKGROUND

Family-based interventions are efficacious at preventing and controlling childhood overweight and obesity; however, implementation is often hindered by low parent engagement. The purpose of this study was to evaluate predictors of parent engagement in a family-based childhood obesity prevention and control intervention.

METHODS

Predictors were assessed in a clinic-based community health worker (CHW)-led Family Wellness Program consisting of in-person educational workshops attended by parents and children. This program was part of a larger effort known as the Childhood Obesity Research Demonstration projects. Participants included 128 adult caretakers of children ages 2-11 (98% female). Predictors of parent engagement (e.g., anthropometric, sociodemographic, psychosocial variables) were assessed prior to the intervention. Attendance at intervention activities was recorded by the CHW. Zero-inflated Poisson regression was used to determine predictors of non-attendance and degree of attendance.

RESULTS

Parents' lower readiness to make behavioral and parenting changes related to their child's health was the sole predictor of non-attendance at planned intervention activities in adjusted models (OR = 0.41, p < .05). Higher levels of family functioning predicted degree of attendance (RR = 1.25, p < .01).

CONCLUSIONS

To improve engagement in family-based childhood obesity prevention interventions, researchers should consider assessing and tailoring intervention strategies to align with the family's readiness to change and promote family functioning.

Determinants of dropout and compliance of children participating in a multidisciplinary intervention programme for overweight and obesity in socially deprived areas

BACKGROUND

Children with overweight and obesity in socially deprived areas (SDAs) are less likely to complete and be compliant to a weight-loss programme.

OBJECTIVES

To identify factors associated with dropout and compliance of a multidisciplinary weight-loss programme in SDA.

METHODS

This prospective longitudinal cohort study included children (6-12 years) with overweight and obesity in a 12-week multidisciplinary intervention living in SDA in Rotterdam, the Netherlands. Potential predictive variables for dropout and compliance included were age, sex, the weight of the child and parents, quality of life, and referral status (self-registration or referral). A Cox proportional hazards model was performed to study the association between dropout and its potential predictive variables, whereas logistic regression analyses were used for the potential predictors for compliance.

RESULTS

A total of 121 children started the intervention programme. Forty-one (33.9%) children dropped out and 68 (56.2%) were compliant with the intervention. The risk of dropping out of the intervention was significantly lower for a child with overweight parents than for those with parents with normal weight (adjusted hazard ratio [HR] 0.22 [95% confidence interval, CI 0.063-0.75]), and for those with parents with obesity (adjusted HR 0.18 [95% CI 0.060-0.52]). No other potential predictive variables were associated with dropout or compliance.

CONCLUSION

Children from SDA participating in a weight-loss programme have a relatively high dropout and a low compliance rate. Parental weight seems to be an important predictor for dropout of children from SDA, where children with normal weight or obese parents have the highest risk of dropout compared with children of overweight parents.

Participants' Engagement With Telephone Support Interventions to Promote Healthy Feeding Practices and Obesity-Protective Behaviours for Infant Obesity Prevention

BACKGROUND

Participant engagement with program interventions is vital to support intended behaviour changes and outcomes. The aim of this research was to investigate participant engagement with the Communicating Healthy Beginnings Advice by Telephone (CHAT) program, an early childhood obesity prevention program that included interventions for promoting healthy infant feeding practices and obesity-protective behaviours via telephone, and whether engagement with the telephone support program varied by participants' sociodemographic characteristics.

METHODS

This study used de-identified CHAT program data of participants who received the interventions via telephone. Data analysed included 1) participant engagement in telephone support from late pregnancy to 12 months of child's age, 2) demographic characteristics collected at late pregnancy and 3) intervention providers' observations and notes (qualitative data) for 10 participants from each engagement group (low, medium, high) to explore issues discussed during telephone support.

RESULTS

Call completion rate by participants was above sixty percent for all six stages of the telephone support program with more than half of the participants (57%) demonstrating high level of engagement. We found that participants' country of birth, employment status and annual household income were predictors of engagement with the telephone support provided in the CHAT program. The odds of participants' engagement with the telephone support program were 1.68 times higher for Australian born (95% CI 1.07 - 2.62), 1.63 times higher for participants who were employed (95% CI 1.01 - 2.66) and 1.63 times higher for participants with annual household income ≥AUD$80,000 (95% CI 1.02 - 2.60).

CONCLUSIONS

Participant engagement with the program interventions was good. Participants' engagement with the telephone support program was significantly associated with certain socio-demographic characteristics. Australian born participants, and participants associated with higher household income and employment engaged significantly more with the telephone support provided in the CHAT program. Additionally, the program engaged more participants older than 30 years of age and those who spoke English at home. The program provided unintended personal benefits to some participants with high engagement level due to their various psychosocial needs such as domestic violence, mental health and sleep related issues. Although not an intended benefit of the intervention, psychosocial needs of participants were met which was a likely factor for mothers' engagement with the program. This is an important factor that needs to be considered while implementing future programs or scale up of this program.

Determinants of attrition in a pediatric healthy lifestyle intervention: The CIRCUIT program experience

INTRODUCTION

Attrition in pediatric weight management programs is notoriously high. Greater understanding of its determinants is needed to inform retention strategies. We identified determinants of attrition in CIRCUIT, a healthy lifestyle intervention program for youth at risk of cardiovascular disease.

METHODS

A one-arm intervention study of children aged 4-18 years who initiated the CIRCUIT program in the first five years of its existence (N = 403). We defined attrition as attending the baseline visit but ceasing attendance prior to the 1-year follow-up. Potential determinants of dropout included the child's age, sex, ethnicity, body mass index (BMI) z-score, family socio-demographic characteristics, and estimated driving time to the program, all measured at baseline. Associations were estimated bivariately, using chi-squared- and t-tests, and simultaneously in a multivariable logistic regression model.

RESULTS

Of the 403 participants who started the program, 198 (49%) dropped out within 12 months of enrollment. Youth who dropped out were older (mean age 12.8y vs. 11.3y; p < 0.01), were less likely to live with both parents (62% vs. 71%; p = 0.05), and to have mothers who had completed high school (79% vs. 88%; p = 0.01). No group differences were observed for sex, ethnicity, baseline BMI z-score, fathers' education, or driving time to the program. In multivariate models, only older age at initiation of the intervention (OR: 1.2; CI: 1.1,1.3) and lower maternal education (OR: 2.0; CI: 1.0,3.8) were associated with dropout.

CONCLUSION

Improved tailoring of interventions to older pediatric participants and to families of lower maternal education may help reduce attrition in CIRCUIT and similar lifestyle intervention programs.

Factors associated with dropout in a lifestyle modification program for weight management in children and adolescents

BACKGROUND

Significant dropout rates remain a serious concern in pediatric weight control program, but few studies have identified predictors of dropout.

AIMS

The objective of the study is to identify factors associated with dropout from a pediatric lifestyle modification weight control program at different phases.

METHODS

Data on overweight and obese participants (n = 242) aged 11-18 years in the Intervention for Childhood and Adolescent Obesity via Activity and Nutrition (ICAAN) study were collected at baseline, 6-months, and 24-months through self-report and a laboratory test. Logistic regression analysis was performed for those who dropped out during the first 6-months, and multivariate generalized estimating equation analysis identified longitudinal factors associated with those who dropped out after 24 months.

RESULTS

Lower family functioning (OR = 2.30, 95% CI [1.18-4.46]), exercise group (OR = 0.36, 95% CI [0.15-0.86]), lower initial attendance rate (OR = 6.09, 95% CI [2.94-12.6]), and non-self -referral pathways (OR = 2.35, 95% CI [1.05-5.27]) were significantly associated with 6-month dropouts. For late dropout, lower family functioning (OR = 1.71, 95% CI [1.06-2.77]) and lower initial attendance rates (OR = 2.06, 95% CI [1.12-3.81]) remained significant.

CONCLUSION

Family function and initial attendance rate were associated with lower dropout rates. Developing a supportive family environment and focusing on the early-stage factors at the intervention's outset may reduce overall dropout rates in obesity prevention intervention.

Perspectives and Impact of a Parent-Child Intervention on Dietary Intake and Physical Activity Behaviours, Parental Motivation, and Parental Body Composition: A Randomized Controlled Trial

Adults and children in Canada are not meeting physical activity guidelines nor consuming sufficient nutrient-rich foods. High engagement in these unhealthy behaviours can lead to obesity and its associated diseases. Parent-child interventions aimed at obesity prevention/treatment have assisted families with making positive changes to their nutrition and physical activity behaviours. Given that the home environment shapes early health behaviours, it is important to target both parents and children when addressing diet and physical activity. One method that has been shown to improve health outcomes is co-active coaching. The current study explored the impact of a three-month co-active coaching and/or health education intervention on the dietary intake and physical activity behaviours of parents with overweight/obesity and their children (ages 2.5-10; of any weight). Body composition (i.e., body mass index [BMI] and waist circumference), changes in parental motivation with respect to physical activity and dietary behaviours, and parental perceptions of program improvements were collected. A concurrent mixed methods study comprised of a randomized controlled trial and a descriptive qualitative design was utilized. Fifty parent-child dyads were recruited and randomly assigned to the control (n = 25) or intervention (n = 25) group. Assessments were completed at baseline, mid-intervention (six weeks), post-intervention (three months), and six-month follow-up. A linear mixed effects model was utilized for quantitative analysis. Inductive content analysis was used to extract themes from parent interviews. No significant results were observed over time for the dependent measures. Parents in both control and intervention groups reported varied program experiences, including developing changes in perspective, increased awareness of habits, and heightened accountability for making positive changes in themselves, and consequently, their families. Parents also shared barriers they faced when implementing changes (e.g., time, weather, stress). Qualitatively, both groups reported benefitting from this program, with the intervention group describing salient benefits from engaging in coaching. This research expands on the utility of coaching as a method for behaviour change, when compared to education only, in parents with overweight/obesity and their children.

Acceptability of Hospital-Based Pediatric Weight Management Services among Patients and Families: A Narrative Synthesis

High rates of attrition from pediatric weight management services are well documented in the literature; however, studies reporting on acceptability of "real-world" services have not previously been reviewed. This narrative synthesis aimed to summarize quantitative and qualitative research reporting on satisfaction of families who attended a secondary or tertiary pediatric weight management service. Electronic databases were searched for studies of family and/or patient satisfaction with hospital-based pediatric weight management services. Included articles were scored on their methodological quality. Searches returned 4509 articles of which 17 were eligible. Education, practical strategies to assist behavior change and the approach of staff were reported as the most valued service aspects. Practical, organizational, and service content issues were reported as the primary reasons for poor engagement or discontinuation of treatment. The majority of recommendations for service improvement related to service content, with the following subthemes: program content, delivery of the weight management intervention, individualized treatment, and treatment expectations. Potential strategies for reducing attrition and improving consumer satisfaction include assessment of families' readiness to change at the outset of treatment and implementation of treatment non-negotiables. Development of a standardized measure of patient satisfaction for use in pediatric weight management service development, evaluation, and comparison is recommended.

Feasibility, acceptability, and effectiveness of a multidisciplinary intervention in childhood obesity from primary care: Nutrition, physical activity, emotional regulation, and family

Childhood obesity is a growing problem with a complex aetiology, for which multidisciplinary interventions are required. Our programme describes a novel structured psychosocial family-based intervention targeting the emotional regulation in childhood obesity, using a train trip metaphor aimed at improving healthy lifestyles for the family. The aims were (a) to describe the feasibility and acceptability of this psychosocial family-based intervention among children with overweight or obesity in primary care and (b) to examine the effectiveness of the "ENTREN-F" programme (with family intervention) compared with the "ENTREN" programme (without family intervention) among Spanish children regarding anthropometric variables, physical activity, emotional well-being, and family functioning. Children were randomly allocated to either ENTREN-F programme (n = 30) or psychological intervention for children (ENTREN, n = 40), and assessments were carried out over time (T₀ baseline vs. T₁ post/6-month vs. T₂ 6-month follow-up). Both parent groups expressed high levels of satisfaction with the interventions. ENTREN-F resulted in higher adherence to treatment and was more effective in improving z-body mass index, reducing children's anxiety, and increasing family adaptability than the ENTREN programme. There were no significant changes in parents' emotional well-being and expressed emotion. Both groups improved in the children's emotional well-being and light physical activity. In summary, this multidisciplinary psychosocial family-based intervention was succesful.

Adherence and barriers in e-health self-control training for enhancing childhood multidisciplinary obesity treatment

Training self-control as the assumed underlying mechanism for weight loss is a promising pathway for improving long-term outcomes of childhood multidisciplinary obesity treatment (MOT). The present study is the first to analyse adherence to e-health self-control training in paediatric obesity. We hypothesized that low adherence would relate to child characteristics and to contextual treatment barriers. Participants were recruited as a part of a larger randomized controlled trial, evaluating an e-health self-control training during inpatient MOT (intensive phase) and its outpatient aftercare (booster phase). A number of 68 youngsters with severe obesity between 11 to 19 years old were included in the present study. Excellent adherence was observed in the intensive phase during inpatient MOT, but rates decreased in the booster phase. As predicted, the low adherence group had a significantly higher weight status throughout the entire study period. Differences in contextual treatment barriers did not appear. Further in-depth analysis showed that the low adherence group frequently experienced practical obstacles. The end of inpatient MOT and high weight status can be considered important risk factors for low adherence in an additional self-control training aimed at facilitating weight loss.

Participant experiences in a paraprofessional-led weight management program for children and families

Background:

Pediatric obesity is a serious and widespread medical condition that is increasing in the United States. Unfortunately, family-based programming to address the disorder fails to successfully reach and engage many children, particularly in low-income communities. To provide more affordable, accessible, and scalable programming options, researchers partnered with pediatricians and the Cooperative Extension Service (Extension) in a Midwestern state to develop a collaborative intervention. Partnering pediatricians referred children and families to a weight management program delivered by a trained Extension paraprofessional. The current study describes family experiences with the program.

Methods:

Researchers conducted a focus group or family interview with 13 program completers to elicit program perceptions, experiences with paraprofessionals, and motivators to continue. The focus group and family interviews were audio recorded and transcribed verbatim for textual analysis. Using thematic analysis, researchers examined patterns across transcripts and formulated emerging themes.

Results:

Key themes that emerged included (1) nutrition guidance, (2) interaction, (3) child influence, and (4) family engagement. Families viewed paraprofessionals as compassionate and competent educators who were instrumental in helping families modify health-related behaviors.

Conclusions:

Results of the current study are important to efforts focused on addressing childhood obesity, particularly in underserved communities where access to healthcare services is limited.

Understanding engagement in a family-focused, multicomponent, childhood weight management programme delivered in the community setting

OBJECTIVE

To describe public health nurses' (PHN) experiences of referring to, and families' experiences of being referred to, a multicomponent, community-based, childhood weight management programme and to provide insight into families' motivation to participate in and complete treatment.

DESIGN

Qualitative study using semi-structured interviews and the draw-and-write technique.

SETTING

Two geographical regions in the south and west of Ireland.ParticipantsNine PHN involved in the referral process, as well as ten parents and nine children who were referred to and completed the programme, participated in the present study.

RESULTS

PHN were afraid of misclassifying children as obese and of approaching the subject of excess weight with parents. Peer support from other PHN as well as training in how best to talk about weight with parents were potential strategies suggested to alleviate these fears. Parents recalled the anxiety provoked by the 'medical terminology' used during referral and their difficulty interpreting what it meant for the health of their child. Despite initial fears, concern for their children's future health was a major driver behind their participation. Children's enjoyment, the social support experienced by parents as well as staff enthusiasm were key to programme completion.

CONCLUSIONS

The present study identifies the difficulties of referring families to community weight management programmes and provides practical suggestions on how to support practitioners in making referrals. It also identifies key positive factors influencing parents' decisions to enrol in community weight management programmes. These should be maximised by staff and policy makers when developing similar programmes.

A Qualitative Examination of Parent Engagement in a Family-Based Childhood Obesity Program

Low parent engagement is frequently identified as a barrier to effective implementation of family-based childhood obesity prevention and control programs. A more nuanced understanding of factors affecting parent engagement is important for improving implementation and, ultimately, program efficacy. This qualitative study examined factors influencing parent engagement in a family-based childhood obesity prevention and control program. Semistructured interviews informed by the health belief model and the transtheoretical model were conducted with 22 predominantly Latina mothers following the scheduled conclusion of program activities. Spanish- and English-language interviews were transcribed, translated into English (if Spanish), coded, and summarized using established protocols. Differences between parents who attended at least two thirds of program activities and those who did not were examined. There were no significant demographic differences between parents who did and did not complete two thirds of program activities. Findings indicated that differences in parent engagement may be at least partially explained by differences in parental motivations for participating and in barriers and facilitators, such as children's level of support and enthusiasm for the program. Parents were highly satisfied with the program content and the community health workers who delivered the program. This study adds to emergent literature regarding parents' experiences in family-based childhood obesity prevention and control programs. Potential targets for improving program engagement are discussed.

Why consistent completion criterion are required in childhood weight management programmes

OBJECTIVES

Current research in the field of childhood weight management (WM) effectiveness is hampered by inconsistent terminology and criterion for WM programme completion, alongside other engagement-related concepts (e.g. adherence, dropout and attrition). Evidence reviews are not able to determine conclusive intervention effectiveness because of this issue. This study aims to quantify how various completion criterion impacts upon on: 1) the percentage of WM completers; 2) the standardised body mass index (BMI SDS) reduction; and 3) the predictors of WM completion.

STUDY DESIGN

A methodological, sensitivity analysis to examine how differential completion criterion affect programme outcomes and predictors.

METHODS

Secondary data of 2948 children were used. All children attended a MoreLife WM programme between 2009 and 2014. The completion criterion was incrementally adjusted by 10% (i.e. completer attends 10%, 20%, 30%... of sessions) for research aims 1-2, with the percentage of completers and change in BMI SDS calculated at each increment. For aim 3, the stability (strength, direction and significance) of the predictors were examined when using the completion criterion of four alternative studies against our previous study (completion ≥70% attendance).

RESULTS

The volume of programme completers decreased in a linear manner as the completion criterion became more stringent (i.e. 70-100% attendance). The change in BMI SDS conversely became incrementally greater. The strength, direction and significance of the predictors was highly dependent on the completion criterion; the odds ratio varied by 24.2% across a single predictor variable (delivery period). The degree of change is evidenced in the paper.

CONCLUSIONS

Inconsistent completion criterion greatly limits the synthesis of programme effectiveness and explains some of the inconsistency in the predictors of engagement. Standardised criterion for engagement-related terminology are called for.

Barriers and facilitators to initial and continued attendance at community-based lifestyle programmes among families of overweight and obese children: a systematic review

The success of childhood weight management programmes relies on family engagement. While attendance offers many benefits including the support to make positive lifestyle changes, the majority of families referred to treatment decline. Moreover, for those who do attend, benefits are often compromised by high programme attrition. This systematic review investigated factors influencing attendance at community-based lifestyle programmes among families of overweight or obese children. A narrative synthesis approach was used to allow for the inclusion of quantitative, qualitative and mixed-method study designs. Thirteen studies met the inclusion criteria. Results suggest that parents provided the impetus for programme initiation, and this was driven largely by a concern for their child's psychological health and wellbeing. More often than not, children went along without any real reason or interest in attending. Over the course of the programme, however, children's positive social experiences such as having fun and making friends fostered the desire to continue. The stigma surrounding excess weight and the denial of the issue amongst some parents presented barriers to enrolment and warrant further study. This study provides practical recommendations to guide future policy makers, programme delivery teams and researchers in developing strategies to boost recruitment and minimise attrition.

Loss to follow-up in a randomized controlled trial study for pediatric weight management (EPOC)

BACKGROUND

Attrition is a serious problem in intervention studies. The current study analyzed the attrition rate during follow-up in a randomized controlled pediatric weight management program (EPOC study) within a tertiary care setting.

METHODS

Five hundred twenty-three parents and their 7-13-year-old children with obesity participated in the randomized controlled intervention trial. Follow-up data were assessed 6 and 12 months after the end of treatment. Attrition was defined as providing no objective weight data. Demographic and psychological baseline characteristics were used to predict attrition at 6- and 12-month follow-up using multivariate logistic regression analyses.

RESULTS

Objective weight data were available for 49.6 (67.0) % of the children 6 (12) months after the end of treatment. Completers and non-completers at the 6- and 12-month follow-up differed in the amount of weight loss during their inpatient stay, their initial BMI-SDS, educational level of the parents, and child's quality of life and well-being. Additionally, completers supported their child more than non-completers, and at the 12-month follow-up, families with a more structured eating environment were less likely to drop out. On a multivariate level, only educational background and structure of the eating environment remained significant.

CONCLUSIONS

The minor differences between the completers and the non-completers suggest that our retention strategies were successful. Further research should focus on prevention of attrition in families with a lower educational background.

Study Protocol: A randomized controlled trial evaluating the effect of family-based behavioral treatment of childhood and adolescent obesity-The FABO-study

Background

The purpose of the FABO-study is to evaluate the effect of family-based behavioral social facilitation treatment (FBSFT), designed to target children’s family and social support networks to enhance weight loss outcomes, compared to the standard treatment (treatment as usual, TAU) given to children and adolescents with obesity in a routine clinical practice.

Methods

Randomized controlled trial (RCT), in which families (n = 120) are recruited from the children and adolescents (ages 6–18 years) referred to the Obesity Outpatient Clinic (OOC), Haukeland University Hospital, Norway. Criteria for admission to the OOC are BMI above the International Obesity Task Force (IOTF) cut-off ≥ 35, or IOTF ≥ 30 with obesity related co-morbidity. Families are randomized to receive FBSFT immediately or following one year of TAU. All participants receive a multidisciplinary assessment. For TAU this assessment results in a plan and a contract for chancing specific lifestyle behaviors. Thereafter each family participates in monthly counselling sessions with their primary health care nurse to work on implementing these goals, including measuring their weight change, and also meet every third month for sessions at the OOC. In FBSFT, following assessment, families participate in 17 weekly sessions at the OOC, in which each family works on changing lifestyle behaviors using a structured cognitive-behavioral, socio-ecological approach targeting both parents and children with strategies for behavioral maintenance and sustainable weight change.

Outcome variables include body mass index (BMI; kg/m²), BMI standard deviation score (SDS) and percentage above the IOTF definition of overweight, waist-circumference, body composition (bioelectric impedance (BIA) and dual-X-ray-absorptiometry (DXA)), blood tests, blood pressure, activity/inactivity and sleep pattern (measured by accelerometer), as well as questionnaires measuring depression, general psychological symptomatology, self-esteem, disturbed eating and eating disorder symptoms. Finally, barriers to treatment and parenting styles are measured via questionnaires.

Discussion

This is the first systematic application of FBSFT in the treatment of obesity among youth in Norway. The study gives an opportunity to evaluate the effect of FBSFT implemented in routine clinical practice across a range of youth with severe obesity.

Five-year outpatient programme that provided children with continuous behavioural obesity treatment enjoyed high success rate

AIM

Results from long-time follow-up of obesity treatment in early childhood are lacking. We investigate long-term continuous behavioural childhood obesity treatment and factors of importance for treatment effect.

METHOD

A five-year longitudinal retrospective controlled study of children aged five to 13 years in obesity treatment, divided into three groups depending on age at start of treatment. Outcome is presented as change in degree of obesity, body mass index standard deviation score (BMI SDS), change in weight status and decrease of ≥0.5 BMI SDS units, in relation to a age-matched obese comparison group.

RESULTS

In total, 220 children (46% females) were included. After five years of treatment, the decrease in BMI SDS was significant in all age groups with the largest effect in age group 4-6 years. Compared to the comparison group (n = 369), the decline in BMI SDS was greater (p = 0.001). After five years of treatment, 48% of the patients were cured from their obesity and 72% reached a decline of 0.5 BMI SDS units. Age at start of treatment was the only factor affecting treatment efficacy.

CONCLUSION

The ability to reach a significant weight loss in a paediatric outpatient clinic is promising through a long-term behavioural obesity treatment.

Design programmes to maximise participant engagement: a predictive study of programme and participant characteristics associated with engagement in paediatric weight management

BACKGROUND

Approximately 50% of paediatric weight management (WM) programme attendees do not complete their respective programmes. High attrition rates compromise both programme effectiveness and cost-efficiency. Past research has examined pre-intervention participant characteristics associated with programme (non-)completion, however study samples are often small and not representative of multiple demographics. Moreover, the association between programme characteristics and participant engagement is not well known. This study examined participant and programme characteristics associated with engagement in a large, government funded, paediatric WM programme. Engagement was defined as the family's level of participation in the WM programme.

METHODS

Secondary data analysis of 2948 participants (Age: 10.44 ± 2.80 years, BMI: 25.99 ± 5.79 kg/m(2), Standardised BMI [BMI SDS]: 2.48 ± 0.87 units, White Ethnicity: 70.52%) was undertaken. Participants attended a MoreLife programme (nationwide WM provider) between 2009 and 2014. Participants were classified into one of five engagement groups: Initiators, Late Dropouts, Low- or High- Sporadic Attenders, or Completers. Five binary multivariable logistic regression models were performed to identify participant (n = 11) and programmatic (n = 6) characteristics associated with an engagement group. Programme completion was classified as ≥70% attendance.

RESULTS

Programme characteristics were stronger predictors of programme engagement than participant characteristics; particularly small group size, winter/autumn delivery periods and earlier programme years (proxy for scalability). Conversely, participant characteristics were weak predictors of programme engagement. Predictors varied between engagement groups (e.g. Completers, Initiators, Sporadic Attenders). 47.1% of participants completed the MoreLife programme (mean attendance: 59.4 ± 26.7%, mean BMI SDS change: -0.15 ± 0.22 units), and 21% of those who signed onto the programme did not attend a session.

CONCLUSIONS

As WM services scale up, the efficacy and fidelity of programmes may be reduced due to increased demand and lower financial resource. Further, limiting WM programme groups to no more than 20 participants could result in greater engagement. Baseline participant characteristics are poor and inconsistent predictors of programme engagement. Thus, future research should evaluate participant motives, expectations, and barriers to attending a WM programme to enhance our understanding of participant WM engagement. Finally, we suggest that session-by-session attendance is recorded as a minimum requirement to improve reporting transparency and enhance external validity of study findings.

Getting to More Effective Weight Management in Antipsychotic-Treated Youth: A Survey of Barriers and Preferences

BACKGROUND

Mentally ill youth are at risk for developing obesity, especially when they require antipsychotic treatment; moreover, they may face unique challenges in adhering to behavioral weight loss interventions. The aims of this project were to characterize the challenges families of youth with psychiatric disorders face when engaging in weight loss treatment and to gather information on attitudes and preferences for weight management interventions in this population.

METHODS

We devised a telephone survey to evaluate caregiver-perceived barriers/challenges to and preferences for behavioral weight loss treatment in overweight or obese mentally ill youth ages 6-18 treated with an antipsychotic agent in an outpatient setting.

RESULTS

A total of 26 parents or primary caregivers completed the survey. The most commonly cited barriers to participation in physical activity (PA) and maintaining a healthy diet were child's dislike of PA and child's preference for energy-dense foods, respectively, which were impacted by psychiatric symptoms. Preferences for weight loss treatment included individualized, prescribed meal plans and shopping lists, and exercise support/demonstration, with a preference for Internet or cell phone applications to help with monitoring food intake and exercise.

CONCLUSIONS

These results suggest that targets for obesity treatment in this population include individualized, specific support that takes into account the child's motivation, which is effected by psychiatric symptoms. Tools for providing support may include the use of telehealth visits and mobile device applications for self-monitoring.

Child self-reported motivations for weight loss: impact of personal vs. social/familial motives on family-based behavioral weight loss treatment outcomes

PURPOSE

Parent motivation is related to successful treatment outcome among children enrolled in obesity treatment. However, the impact of child weight loss motivation on treatment outcome has not been investigated. The current study evaluated weight loss motives among treatment-seeking, overweight children, and their relationship to treatment outcome.

METHODS

The current study is a secondary analysis of a primary study examining a parent-only and parent + child childhood obesity treatment. Study participants included 77 children (aged 8-12, 58 % female). Assessments were completed at baseline, post-treatment, and at 6-months post-treatment. Children completed standardized height and weight procedures. In addition, they completed a checklist of reasons children may be motivated to lose weight. Motives were divided into two scales reflecting personal and social/familial reasons to lose weight. Regression analyses were used to calculate associations between the number of weight loss motives endorsed and treatment completion, sessions attended, and child BMI.

RESULTS

A greater number of social/familial motives were significantly predictive of session attendance, treatment completion, and a lower child BMI at the post-treatment assessment.

CONCLUSIONS

Children who are motivated to lose weight because of family/social influences may be more highly engaged in treatment and lose more weight, as compared to children who are less motivated by family and social reasons.

Attrition and the management of pediatric obesity: an integrative review

BACKGROUND

A key challenge in managing pediatric obesity is the high degree of program attrition, which can reduce therapeutic benefits and contribute to inefficient health services delivery. Our aim was to document and characterize predictors of, and reasons for, attrition in pediatric obesity management.

METHODS

We searched literature published until January 2014 in five databases (CINAHL, EMBASE, MEDLINE, PsycINFO, and Scopus). Articles were included if they were English, included participants 0-18 years of age, focused on pediatric obesity management, incorporated lifestyle and behavioral changes without pharmacotherapy, provided attrition data, and reported information about predictors of, and/or reasons for, attrition from family-based interventions provided in research or clinical settings. Twenty-three articles (n=20 quantitative; n=2 qualitative; n=1 mixed methods) met our inclusion criteria. Clarity of study aims, objectives, methods, and data analysis were appraised using Bowling's checklist.

RESULTS

Attrition varied according to definition (minimum to maximum, 4-83%; median, 37%). There were few consistent predictors of attrition between studies, although dropout was higher among US-based families receiving public health insurance. Older children were also more likely to discontinue care, but sex and baseline weight status did not predict attrition. The most commonly reported reasons for attrition were logistical barriers and programs not meeting families' needs.

CONCLUSIONS

Developing and evaluating strategies designed to minimize the risk of attrition, especially among families who receive public health insurance and older boys and girls, are needed to optimize the effectiveness of pediatric obesity management.

Predictors of attrition from a clinical pediatric obesity treatment program

OBJECTIVE

To assess the predictors of attrition from a clinical pediatric obesity treatment program.

METHODS

We evaluated 2- through 20-year-old patients first seen at the Duke University Healthy Lifestyles Program between October 2006 and December 2008. We assessed the predictors of early dropout (not returning for any follow-up visits within 1 year) and of noncompletion (not attending at least 6 visits within 1 year after entry).

RESULTS

The sample included 983 patients. In adjusted analyses, non-white non-Hispanic children were more likely to be early dropouts than white non-Hispanic children (odds ratio [OR] = 1.46, 95% confidence interval [CI] = 1.03-2.07). Non-white non-Hispanic children were more likely to be noncompleters than white non-Hispanic (OR = 1.56, 95% CI = 1.03-2.36) and Hispanic children (OR = 2.56, 95% CI = 1.34-4.90).

CONCLUSIONS

Race/ethnicity predicted patient attrition. Investigation into this association and program modification are needed to reduce attrition in certain racial/ethnic groups.

Childhood obesity and co-morbid problems: effects of Epstein's family-based behavioural treatment in an Icelandic sample

OBJECTIVE

This study assessed the effects of Epstein's family-based behavioural treatment in a clinical sample of obese children in Iceland. Also, it explored whether co-morbid concerns affect treatment outcome.

METHODS

Eighty-four obese children [mean body-mass-index standard-deviation-scores (BMI-SDS) = 3.11, aged 7.5-13.6 years] and a participating parent initiated treatment in response to a school-based screening. Sixty-one families completed treatment and were followed for 1 year post treatment. Measurements included height, weight, reports of psychological well-being (Strengths and Difficulties Questionnaire, Multidimensional Anxiety Scale for Children, Children's Depression Inventory, Piers-Harris Self Concept Scale, Social Skills Rating System) and academic competencies.

RESULTS

Among treatment completers a large effect size was obtained for change in BMI-SDS during treatment (mean difference = -0.40, SD = 0.29). Psychological well-being improved and treatment effects were maintained at 1-year follow-up. At baseline, 69% of the children presented with one or more co-morbid concerns. Children who scored above cut-off for concern on parent-reported hyperactivity (Strengths and Difficulties Questionnaire subscale T-score ≥ 65) reduced their BMI-SDS less during treatment than children with lower hyperactivity scores whereas children who scored in the clinical range for social anxiety (Multidimensional Anxiety Scale for Children subscale T-score ≥ 65) reduced their BMI-SDS significantly more than children with lower social anxiety scores. The social anxiety effect was still present at 1-year follow-up, but not the hyperactivity effect (P > 0.05). No differential response was shown for children with higher depression scores, lower self-concept or low academic competencies.

CONCLUSIONS

Epstein's family-based behavioural treatment produced promising effects in both the short and the longer term in a clinical sample of Icelandic children with substantial rates of co-morbid concerns. Co-morbid problems affect outcome and tailoring treatment to address co-morbid concerns might improve outcomes for certain subgroups.

Lessons learned from a family-focused weight management intervention for obese and overweight children

Objective

Treatment for childhood obesity is characterised by high attrition rates and failure to achieve weight maintenance. It is therefore important to develop more effective programmes. The aim of the present qualitative study was to explore the views of parents, children and health trainers to identify issues which can inform the development of more effective programmes.

Design

A qualitative study combining in-depth interviews and focus groups. Participants were selected purposively from current and past attendees.

Setting

WATCH-IT, a UK-based community child weight management programme.

Subjects

Twenty-three families who had previously attended (or were currently attending) WATCH-IT were interviewed. Focus groups with ten trainers explored their views of the intervention.

Results

Parents and children had different goals for involvement, with parents focusing on psychological benefits, while children concentrated on goals relating to weight loss and physical fitness. Parents were found to struggle to provide consistent support to their children and this was exacerbated by family dynamics. The child's commitment to lose weight, support from their family and a good relationship between the child and their trainer were viewed as important keys to successful weight management.

Conclusions

The study will guide the design of existing and future programmes by providing insights into issues that challenge successful engagement. It highlights the possible value of exploring the therapeutic relationship between trainers and participants.

Counseling and behavior change in pediatric obesity

To effectively intervene with the overweight and obese youth, it is imperative that primary care providers and behavioral interventionists work in concert to help families implement healthy behaviors across socioenvironmental domains. In this article, the authors review current office-based counseling practices and provide evidence-based recommendations for addressing weight status and strategies for encouraging behavior change with children and families, primarily by increasing social support. By providing such collaborative targeted efforts, consistent health messages and support are delivered across children's everyday contexts, thereby helping the youth to achieve successful implementation of eating and activity behaviors and sustainable weight loss outcomes.

The role of parental motivation in family-based treatment for childhood obesity

This study investigated the role of parental motivation (importance, confidence and readiness) for predicting dropout and outcome from family-based behavioral treatment for childhood obesity. Parent and child demographics, adherence to treatment, and weight loss parameters were also explored as potential predictors. Eighty-four obese children (BMI-standard deviation scores (SDS) >2.14) and a participating parent with each child started treatment consisting of 12 weeks of group and individual treatment sessions (24 sessions total) delivered over a period of 18 weeks. Sixty-one families (73%) completed treatment and attended follow-up at 1 year after treatment. Child session attendance and completion of self-monitoring records served as measures of adherence. In regression analyses, parent reports (pretreatment) of confidence for doing well in treatment was the strongest predictor of treatment completion (P = 0.003) as well as early treatment response (weight loss at week 5) (P = 0.003). This variable remained a significant predictor of child weight loss at post-treatment (P = 0.014), but was not associated with child outcome at 1-year follow-up (P > 0.05). The only significant predictor of child weight loss at that point was child baseline weight (P = 0.001). However, pretreatment parent ratings of importance of and readiness for treatment did not predict dropout or weight loss at any point. The results underscore the importance of addressing parental motivation, specifically parental confidence for changing lifestyle related behaviors, early in the treatment process. Doing so may reduce treatment dropout and enhance treatment outcome.

Training Parents of Overweight Children in Parenting Skills: A 12-Month Evaluation

Background: The origins of childhood obesity invariably need to be looked at within a family context and several reviews have concluded in favour of parental involvement in the treatment of paediatric obesity. However, there is little consensus on the format, and next to weight outcomes behavioural outcomes also merit more attention when assessing program effectiveness. Method: In this pilot study, a total of 50 families with overweight children (aged 6–12) were randomly allocated to a parent-led intervention group (cognitive behavioural training) or to a waiting list control group (Study 1). Afterwards, the parents of the waitlist control group also followed the intervention. All children were included in a follow-up study and were compared with a reference group (Study 2). Results: The intervention group as well as the waitlist group (who had not yet received treatment) showed a decrease in adjusted BMI over a 6-month period, although the decrease was only significant for the intervention group (Study 1). All children showed a decrease of 7% in adjusted BMI from pre to one-year follow-up measurement (Study 2), while the reference group showed an increase in adjusted BMI over that period. Parents reported significant positive changes in children's eating behaviour and a significant positive increase in familial health principles. Conclusions: Weight and behavioural outcomes suggest potential for intervention effectiveness. Long-term follow-up is needed to reveal residual benefits of enhanced parenting skills on environmental lifestyle changes.

Somatic complaints and social competence predict success in childhood overweight treatment

OBJECTIVE

To determine baseline predictors of treatment success in terms of Body Mass Index-Standard Deviation Scores (BMI-SDS) in a multidisciplinary family-based behavioural lifestyle intervention for overweight and obese children.

METHODS

Overweight and obese children (N = 248; age 8-14 years) and their caregivers participated in a prospective study and attended a lifestyle intervention. Baseline data assessment included anthropometrics, demographics, breakfast behaviour, competence and behavioural problems (Child Behaviour Checklist [CBCL]), family functioning (Family Adaptability and Cohesion Evaluation Scales [FACES] III), and personality (Dutch Personality Questionnaire-Youth [NPV-J]). BMI-SDS was measured at start and after 3, 9, and 12 months of treatment. Mixed modelling was used for analysis.

RESULTS

Greater BMI-SDS reductions over the course of one year were found in children with Caucasian parents, with lower baseline BMI-SDS, and higher CBCL-social competence scores. Furthermore, children with non-overweight parents, younger children, and children with lower CBCL-somatic scores were more successful in BMI-SDS reduction. No effects on treatment success were found for the number or position of siblings, having divorced parents or a working mother, educational level of the parents, breakfast behaviour, family functioning, and personality.

CONCLUSIONS

These results suggest that screening for baseline characteristics in childhood obesity treatment could identify who will benefit most from a paediatric lifestyle intervention. Tailored programs should be developed and the treatment team should focus on children who are less successful in achieving weight reductions. Future research should study by which mechanisms somatic complaints and social competence influence treatment success.
