Single versus multiple-family intervention in childhood overweight--Finnmark Activity School: a randomised trial

Changes in dietary habits and BMI z-score after a 6-month non-randomized cluster-controlled trial among 6-12 years old overweight and obese Norwegian children

Background

Effective prevention programs to address the high prevalence of childhood overweight and obesity and the concomitant health consequences have been warranted.

Objective

To improve dietary habits and weight status among Norwegian children with overweight/obesity in the primary care setting.

Design

A 6-month non-randomized cluster-controlled intervention among 137 children, aged 6-12 years, with overweight/obesity and their parents. Intervention and control groups were recruited by public health nurses and followed-up by 12 Healthy Life Centers across Norway. The intervention group received individual family counseling and participated in nutrition courses and physical activity groups. A frequency questionnaire assessing sociodemographic characteristics and dietary habits was completed by the parents. Trained public health nurses measured height and weight using standardized methods to calculate body mass index (BMI) and BMI z-scores.

Results

The intervention resulted in an increased odds of consuming evening meals (OR: 3.42), a decreased availability of salty snacks (β = -0.17), a decreased intake of salty snacks (-0.18), an increased consumption of water (β = 0.20), and a decreased estimated total intake of energy (β = -0.17), carbohydrates (β = -0.17), mono- and disaccharides (β = -0.21), sucrose (β = -0.24), and saturated fatty acids (β = -0.17). The intervention directly predicted lower BMI z-score (β = -0.17), and post-treatment levels of energy (β = -0.65), saturated fat (β = 0.43), and total carbohydrates (β = 0.41) were directly linked to BMI z-score after intervention. Age and sex were indirectly associated with BMI after intervention through energy and saturated fat intake.

Conclusions

The intervention had a beneficial impact on nutrient intake and weight status among children with overweight/obesity. These findings provide support for implementing complex intervention programs tailored to local primary care settings.

Appraisal of Clinical Care Practices for Child Obesity Treatment. Part I: Interventions

The objective of this technical report is to provide clinicians with evidence-based, actionable information upon which to make assessment and treatment decisions for children and adolescents with obesity. In addition, this report will provide an evidence base to inform clinical practice guidelines for the management and treatment of overweight and obesity in children and adolescents. To this end, the goal of this report was to identify all relevant studies to answer 2 overarching key questions: (KQ1) "What are clinically based, effective treatments for obesity?" and (KQ2) "What is the risk of comorbidities among children with obesity?" See Appendix 1 for the conceptual framework and a priori key questions.

Solution Focused Brief Therapy Telemental Health Suicide Intervention

One of the innumerable impacts of the coronavirus has been the change in how individuals provide services. For mental health providers, the pandemic required a sudden shift from in person to online service delivery. As therapists learn and embrace a new modality for providing therapy, crisis situations may present with some anxiety. With the pandemic increasing crisis situations for so many individuals, and teletherapy as a mode of service delivery being unlikely to go away after the pandemic, therapists require support in navigating crises situations online, in a medium that feels like the therapist has less control with their clients due to being in different physical locations. The authors believe that regardless of the primary model(s) therapists utilize in session, solution-focused brief therapy is an integrative model that uniquely captures client's resources and reasons for living and when clients are in crisis. The purpose of this paper is to present recommendations for applying solution-focused language in teletherapy practice, to provide ethical, evidenced based care for clients in crisis. A clinical vignette is used to illustrate the application of solution focused brief therapy for working with clients in crisis. Future directions and limitations are discussed.

Age, income and sleep duration were associated with outcomes in children participating in weight management

Aim

To explore associations between baseline factors and weight‐related outcomes among participants enrolled in a paediatric obesity trial.

Methods

We included children aged 6–12 years participating in a 2‐year multidisciplinary family programme who attended a postintervention follow‐up 36 months from baseline (n = 62). Outcome measures were change in body mass index standard deviation score (BMI SDS), reduction in BMI SDS ≥0.25 and change in waist circumference (WC). Independent variables included in linear and logistic regression models were age, sex, household income, parents' education, sleep duration, screen time and physical activity.

Results

Altogether, 26 children (42%) attained a reduction of BMI SDS ≥0.25. Higher family income and longer sleep duration were associated with greater change in BMI SDS (−0.05 per 100.000 NOK, p = 0.02, and −0.24 per hour, p = 0.02, respectively). Higher age was associated with greater change in WC (−2.1 cm per year, p = 0.01) but lower odds of attaining a reduction in BMI SDS ≥0.25 (OR per year 0.70, p = 0.04). There was a borderline statistically significant trend towards greater increase in WC with longer daily screen time (p = 0.05).

Conclusion

Age, family income and sleep duration at baseline were associated with weight‐related outcomes 1‐year postintervention.

The effectiveness of nurse-led interventions to prevent childhood and adolescent overweight and obesity: A systematic review of randomised trials

BACKGROUND

Obesity among children and adolescents continues to rise worldwide. Despite the efforts of the healthcare workforce, limited high-quality evidence has been put forward demonstrating effective childhood obesity interventions. The role of nurses as primary actors in childhood obesity prevention has also been underresearched given the size of the workforce and their growing involvement in chronic disease prevention.

AIM

To examine the effectiveness of nurse-led interventions to prevent childhood and adolescent overweight and obesity.

DESIGN

A systematic review of randomised trials.

DATA SOURCES

Medline, CINAHL, EMBASE, Cochrane (CENTRAL), ProQuest Central and SCOPUS were searched from inception to March 2020.

REVIEW METHODS

This review was informed by the Cochrane handbook for systematic reviews of interventions.

RESULTS

Twenty-six publications representing 18 discrete studies were included (nine primary prevention and nine secondary prevention). Nurse-led interventions were conducted in diverse settings, were multifaceted, often involved parents and used education, counselling and motivational interviewing to target behaviour change in children and adolescents' diet and physical activity. Most studies did not determine that nurse-led interventions were more effective than their comparator(s) in preventing childhood and adolescent overweight and obesity.

CONCLUSIONS

Nurse-led interventions to prevent juvenile obesity are feasible but have not yet determined effectiveness. With adequate training, nurses could make better use of existing clinical and situational opportunities to assist in the effort to prevent childhood obesity.

Nurse-led interventions in the prevention and treatment of overweight and obesity in infants, children and adolescents: A scoping review

BACKGROUND AND OBJECTIVE

Nurses are well-placed in primary care, school and community settings to identify and manage paediatric overweight and obesity. This scoping review examined what types of nurse-led interventions have been undertaken for the prevention, treatment and management of obesity and overweight in infants, children and adolescents.

DESIGN

Scoping review.

DATA SOURCES

CINAHL, Cochrane Library, Embase, MEDLINE, ProQuest Central, ProQuest Dissertations & Theses Global, and Scopus. Searches were undertaken from inception to 2019.

METHODS

Database searches and handsearching were used to identify academic and grey literature, such as scientific reports and university theses and dissertations, on nurse-led interventions undertaken in school, primary health care and community settings. Studies focused on addressing overweight and obesity in children and adolescents, for studies published from 1999 onwards. Studies included focused on experimental and quasi-experimental research that implemented interventions, and described new practice or change in practice.

RESULTS

117 references encompassing 83 studies or programs were selected for inclusion. 16 trials were analysed descriptively, and 67 trials were analysed descriptively and quantitatively. The analysis structured intervention settings and outcomes using the socioecological model, encompassing intrapersonal, interpersonal, community, organisation and policy factors. Studies included were clinically heterogeneous for intervention setting and multicomponent strategies. Education for nutrition, physical activity and behaviour change was the most common strategy used, and nutrition and physical activity knowledge most consistently improved after intervention. Nursing roles focused on education; counselling and behaviour change in primary care; advocacy in school and community environments; and implementing policy in child care settings. Fifty-four studies received financial or resource funding and support to implement the study. On sustainability, seven programs and two research studies were ongoing at time of writing.

CONCLUSIONS

While the clinical heterogeneity of studies makes synthesis of outcomes complex, it demonstrates the breadth of nursing interventions to address paediatric overweight and obesity. Incentives that encourage routine health promotion, upskilling of nurses, and embedding food and nutrition education into the school curricula, are suitable strategies that support nurse-led interventions against paediatric obesity.

Layperson-Led vs Professional-Led Behavioral Interventions for Weight Loss in Pediatric Obesity: A Systematic Review and Meta-analysis

IMPORTANCE

The appropriate approach for weight loss among children and adolescents with overweight and obesity remains unclear.

OBJECTIVE

To evaluate the difference in the treatment outcomes associated with behavioral weight loss interventions led by laypersons and professionals in comparison with unsupervised control arms among children and adolescents with overweight and obesity.

DATA SOURCES

For this systematic review and meta-analysis, the Medical Literature Analysis and Retrieval System Online (MEDLINE), Embase, the Cochrane Library, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases were searched from January 1, 1996, to June 1, 2019.

STUDY SELECTION

Included in this study were randomized clinical trials (RCTs) of behavioral interventions lasting at least 12 weeks for children and adolescents (aged 5-18 years) with overweight and obesity. Exclusion criteria included non-RCT studies, interventions lasting less than 12 weeks, adult enrollment, participants with other medical diagnoses, pharmacological treatment use, and articles not written in English. Two of 6 reviewers independently screened all citations. Of 25 586 citations, after duplicate removal, 78 RCTs (5780 participants) met eligibility criteria.

DATA EXTRACTION AND SYNTHESIS

A bayesian framework and Markov chain Monte Carlo simulation methods were used to combine direct and indirect associations. Random-effects and fixed-effect network meta-analysis models were used with the preferred model chosen by comparing the deviance information criteria. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.

MAIN OUTCOMES AND MEASURES

The immediate and sustained changes in weight and body mass index (BMI) standardized mean difference (SMD) were primary outcomes planned before data collection began, whereas waist circumference and percent body fat were secondary outcomes. The hypothesis being tested was formulated before the data collection.

RESULTS

Of 25 586 citations retrieved, we included 78 RCTs (5780 participants), with a follow-up of 12 to 104 weeks. Compared with the control condition, random-effects models revealed that professional-led weight loss interventions were associated with reductions in weight (mean difference [MD], -1.60 kg [95% CI, -2.30 to -0.99 kg]; 68 trials; P < .001) and BMI (SMD, -0.30 [95% CI, -0.39 to -0.20]; 59 trials; P < .001) that were not sustained long term (weight MD, -1.02 kg [95% CI, -2.20 to 0.34 kg]; 21 trials; P = .06; BMI SMD, -0.12 [95% CI, -0.46 to 0.21]; 20 trials; P < .001). There was no association between layperson-led interventions and weight loss in the short-term (MD, -1.40 kg [95% CI, -3.00 to 0.26 kg]; 5 trials; P = .05) or long-term (MD, -0.98 kg [95% CI, -3.60 to 1.80 kg]; 1 trial; P = .23) compared with standard care. No difference was found in head-to-head trials (professional vs layperson MD, -0.25 kg [95% CI -1.90 to 1.30 kg]; 5 trials; P = .38).

CONCLUSIONS AND RELEVANCE

This systematic review and meta-analysis found that professional-led weight loss interventions were associated with short-term but not sustained weight reduction among children and adolescents with overweight or obesity, and the evidence for layperson-led approaches was insufficient to draw firm conclusions.

No additional long-term effect of group vs individual family intervention in the treatment of childhood obesity-A randomised trial

AIM

Long-term evaluations of childhood obesity treatments are needed. We examined changes in weight and cardiometabolic risk 1 year after children completed individual family or group-based weight management interventions.

METHODS

In 2009-2010, 6- to 12-year-old children with overweight or obesity from Finnmark and Troms (Norway) were recruited after media coverage and randomised to 24 months of individual family (n = 49) or group intervention (n = 48). Individual family intervention included counselling by a paediatric hospital team and a public health nurse in the local community. Group intervention included meetings with other families and a multidisciplinary hospital team, weekly physical activity sessions and a family camp. The primary outcome body mass index (BMI) and cardiometabolic risk factors were analysed 12 months after intervention.

RESULTS

From baseline to 36 months, children's BMI increased 3.0 kg/m² in individual family and 2.1 kg/m² in group intervention (between-group -0.9kg/m² , P = 0.096). Data were available from 62 children (64%). Between-group differences in C peptide (P = 0.01) were detected in favour of group intervention. Pooled data from both treatment groups showed continued decrease in BMI standard deviation score (P < 0.001).

CONCLUSION

No between-group difference in BMI was observed 12 months after intervention. Both groups combined showed sustained decrease in BMI standard deviation score.

An Integrated Clinic-Community Partnership for Child Obesity Treatment: A Randomized Pilot Trial

BACKGROUND AND OBJECTIVES

Effective treatment of childhood obesity remains elusive. Integration of clinical and community systems may achieve effective and sustainable treatment. However, the feasibility and effectiveness of this integrated model are unknown.

METHODS

We conducted a randomized clinical trial among children aged 5 to 11 presenting for obesity treatment. We randomized participants to clinical care or clinical care plus community-based programming at a local parks and recreation facility. Primary outcomes were the change in child BMI at 6 months and the intensity of the program in treatment hours. Secondary outcomes included health behaviors, fitness, attrition, and quality of life.

RESULTS

We enrolled 97 children with obesity, and retention at 6 months was 70%. Participants had a mean age of 9.1 years and a mean baseline BMI z score of 2.28, and 70% were living in poverty. Intervention participants achieved more treatment hours than controls (11.4 vs 4.4, SD: 15.3 and 1.6, respectively). We did not observe differences in child BMI z score or percent of the 95th percentile at 6 months. Intervention participants had significantly greater improvements in physical activity (P = .010) and quality of life (P = .008).

CONCLUSIONS

An integrated clinic-community model of child obesity treatment is feasible to deliver in a low-income and racially diverse population. As compared with multidisciplinary treatment, the integrated model provides more treatment hours, improves physical activity, and increases quality of life. Parks and recreation departments hold significant promise as a partner agency to deliver child obesity treatment.

The effectiveness of strength-based, solution-focused brief therapy in medical settings: a systematic review and meta-analysis of randomized controlled trials

This meta-analysis synthesized randomized controlled trials of solution focused brief therapy (SFBT) in medical settings for patients' health-related psychosocial (e.g., depression, psychosocial adjustment to illness), behavioral (e.g., physical activity, nutrition score), and functional health (e.g., BMI, individual strength) outcomes. Medical setting is defined in this study as any healthcare setting that primarily focuses on patients' physical wellbeing. A comprehensive search strategy across five electronic databases, four academic journals, three professional websites, and reference lists of included articles resulted in a final sample of nine studies for meta-analytic synthesis. Combining outcomes indicated an overall significant effect of SFBT for health-related psychosocial outcomes (d = 0.34, p < .05.) and a nearly significant outcome for health-related behavioral outcomes (d = 0.28, p = .06), but not for functional health outcomes. Results indicated SFBT being an effective intervention for psychosocial outcomes and a promising approach for behavioral outcomes in medical settings.

Effectiveness of educational and lifestyle interventions to prevent paediatric obesity: systematic review and meta-analyses of randomized and non-randomized controlled trials

OBJECTIVE

This review and meta-analysis aim at updating a previous meta-analysis carried out by Waters et al. on the efficacy of interventions aimed at preventing childhood obesity and at identifying predictors of outcome.

METHODS

Using an ad-hoc search string, PubMed database was searched for studies assessing body mass index reduction associated with programmes lasting ≥12 weeks in overweight and obese children aged 2-18 years. Studies designed for children with eating disorders or relevant comorbidities were excluded. Studies meeting inclusion criteria were classified according to patient age (<6, 6-12 and 13-18 years), and intervention type (physical activity, diet or both), setting (educational, family or both) and duration (≤1 or >1 year). The search was also extended to other databases. Hand-searching techniques were also applied. The Cochrane 'risk of bias' was applied for quality assessment.

RESULTS

Seventy-two studies were meta-analysed. Overall, the best results were achieved by programmes combining diet and physical activity (n = 39). With regard to the setting, programmes involving both school and family and lasting ≤1 year were the most efficacious for 6- to 12-year-old children (n = 26); family-based-only interventions were also effective in children <6 years old (n = 2), although results have to be interpreted cautiously because of the small number of patients enrolled and the high study heterogeneity. In 13- to 18-year-old patients, interventions delivered at school (n = 8) were substantially unsuccessful.

CONCLUSIONS

Interventions for childhood obesity prevention should include both diet and physical activity, be preferentially targeted towards school age children and involve both the school and family setting. However, because of the important methodological limitations associated with currently available literature, additional studies are needed to draw definite conclusions.

Conceptualising a model to guide nursing and midwifery in the community guided by an evidence review

Background

Successful models of nursing and midwifery in the community delivering healthcare throughout the lifespan and across a health and illness continuum are limited, yet necessary to guide global health services. Primary and community health services are the typical points of access for most people and the location where most care is delivered. The scope of primary healthcare is complex and multifaceted and therefore requires a practice framework with sound conceptual and theoretical underpinnings.

The aim of this paper is to present a conceptual model informed by a scoping evidence review of the literature.

Methods

A scoping evidence review of the literature was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Databases included CINAHL, MEDLINE, PsycINFO and SocINDEX using the EBSCO platform and the Cochrane Library using the keywords: model, nursing, midwifery, community, primary care. Grey literature for selected countries was searched using the Google ‘advanced’ search interface. Data extraction and quality appraisal for both empirical and grey literature were conducted independently by two reviewers. From 127 empirical and 24 non-empirical papers, data extraction parameters, in addition to the usual methodological features, included: the nature of nursing and midwifery; the population group; interventions and main outcomes; components of effective nursing and midwifery outcomes.

Results

The evidence was categorised into six broad areas and subsequently synthesised into four themes. These were not mutually exclusive: (1) Integrated and Collaborative Care; (2) Organisation and Delivery of Nursing and Midwifery Care in the Community; (3) Adjuncts to Nursing Care and (4) Overarching Conceptual Model. It is the latter theme that is the focus of this paper. In essence, the model depicts a person/client on a lifespan and preventative-curative trajectory. The health related needs of the client, commensurate with their point position, relative to both trajectories, determines the nurse or midwife intervention. Consequently, it is this need, that determines the discipline or speciality of the nurse or midwife with the most appropriate competencies.

Conclusion

Use of a conceptual model of nursing and midwifery to inform decision-making in primary/community based care ensures clinical outcomes are meaningful and more sustainable. Operationalising this model for nursing and midwifery in the community demands strong leadership and effective clinical governance.

Diet, physical activity and behavioural interventions for the treatment of overweight or obese children from the age of 6 to 11 years

BACKGROUND

Child and adolescent overweight and obesity has increased globally, and can be associated with significant short- and long-term health consequences. This is an update of a Cochrane review published first in 2003, and updated previously in 2009. However, the update has now been split into six reviews addressing different childhood obesity treatments at different ages.

OBJECTIVES

To assess the effects of diet, physical activity and behavioural interventions (behaviour-changing interventions) for the treatment of overweight or obese children aged 6 to 11 years.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, LILACS as well as trial registers ClinicalTrials.gov and ICTRP Search Portal. We checked references of studies and systematic reviews. We did not apply any language restrictions. The date of the last search was July 2016 for all databases.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) of diet, physical activity, and behavioural interventions (behaviour-changing interventions) for treating overweight or obese children aged 6 to 11 years, with a minimum of six months' follow-up. We excluded interventions that specifically dealt with the treatment of eating disorders or type 2 diabetes, or included participants with a secondary or syndromic cause of obesity.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened references, extracted data, assessed risk of bias, and evaluated the quality of the evidence using the GRADE instrument. We contacted study authors for additional information. We carried out meta-analyses according to the statistical guidelines in the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

We included 70 RCTs with a total of 8461 participants randomised to either the intervention or control groups. The number of participants per trial ranged from 16 to 686. Fifty-five trials compared a behaviour-changing intervention with no treatment/usual care control and 15 evaluated the effectiveness of adding an additional component to a behaviour-changing intervention. Sixty-four trials were parallel RCTs, and four were cluster RCTs. Sixty-four trials were multicomponent, two were diet only and four were physical activity only interventions. Ten trials had more than two arms. The overall quality of the evidence was low or very low and 62 trials had a high risk of bias for at least one criterion. Total duration of trials ranged from six months to three years. The median age of participants was 10 years old and the median BMI z score was 2.2.Primary analyses demonstrated that behaviour-changing interventions compared to no treatment/usual care control at longest follow-up reduced BMI, BMI z score and weight. Mean difference (MD) in BMI was -0.53 kg/m2 (95% confidence interval (CI) -0.82 to -0.24); P < 0.00001; 24 trials; 2785 participants; low-quality evidence. MD in BMI z score was -0.06 units (95% CI -0.10 to -0.02); P = 0.001; 37 trials; 4019 participants; low-quality evidence and MD in weight was -1.45 kg (95% CI -1.88 to -1.02); P < 0.00001; 17 trials; 1774 participants; low-quality evidence.Thirty-one trials reported on serious adverse events, with 29 trials reporting zero occurrences RR 0.57 (95% CI 0.17 to 1.93); P = 0.37; 4/2105 participants in the behaviour-changing intervention groups compared with 7/1991 participants in the comparator groups). Few trials reported health-related quality of life or behaviour change outcomes, and none of the analyses demonstrated a substantial difference in these outcomes between intervention and control. In two trials reporting on minutes per day of TV viewing, a small reduction of 6.6 minutes per day (95% CI -12.88 to -0.31), P = 0.04; 2 trials; 55 participants) was found in favour of the intervention. No trials reported on all-cause mortality, morbidity or socioeconomic effects, and few trials reported on participant views; none of which could be meta-analysed.As the meta-analyses revealed substantial heterogeneity, we conducted subgroup analyses to examine the impact of type of comparator, type of intervention, risk of attrition bias, setting, duration of post-intervention follow-up period, parental involvement and baseline BMI z score. No subgroup effects were shown for any of the subgroups on any of the outcomes. Some data indicated that a reduction in BMI immediately post-intervention was no longer evident at follow-up at less than six months, which has to be investigated in further trials.

AUTHORS' CONCLUSIONS

Multi-component behaviour-changing interventions that incorporate diet, physical activity and behaviour change may be beneficial in achieving small, short-term reductions in BMI, BMI z score and weight in children aged 6 to 11 years. The evidence suggests a very low occurrence of adverse events. The quality of the evidence was low or very low. The heterogeneity observed across all outcomes was not explained by subgrouping. Further research is required of behaviour-changing interventions in lower income countries and in children from different ethnic groups; also on the impact of behaviour-changing interventions on health-related quality of life and comorbidities. The sustainability of reduction in BMI/BMI z score and weight is a key consideration and there is a need for longer-term follow-up and further research on the most appropriate forms of post-intervention maintenance in order to ensure intervention benefits are sustained over the longer term.

Multicomponent Lifestyle Interventions for Treating Overweight and Obesity in Children and Adolescents: A Systematic Review and Meta-Analyses

BACKGROUND

Treatment of childhood obesity is important in preventing development of obesity-related diseases later in life. This systematic review evaluates the effect of multicomponent lifestyle interventions for children and adolescents from 2 to 18 years.

METHODS AND RESULTS

We performed systematic searches in nine databases. Thirty-nine studies met the criteria for meta-analyses. We found a significant difference in body mass index (BMI) after 6 months (MD -0.99 (95% CI -1.36 to -0.61)), 12 months (MD -0.67 (95% CI -1.01 to -0.32)), and 24 months (MD -0.96 (95% CI -1.63 to -0.29)) in favour of multicomponent lifestyle interventions compared to standard, minimal, and no treatment. We also found a significant difference in BMI Z scores after 6 months (MD -0.12 (95% CI -0.17 to -0.06)), 12 months (MD -0.16 (95% CI -0.21 to -0.11)), and 24 months (MD -0.16 (95% CI -0.21 to -0.10)) in favour of multicomponent lifestyle interventions. Subgroup analyses suggested an increased effect in specialist health care with a group treatment component included in the intervention.

CONCLUSION

Multicomponent lifestyle interventions have a moderate effect on change in BMI and BMI Z score after 6, 12, and 24 months compared with standard, minimal, and no treatment.

The More and Less Study: a randomized controlled trial testing different approaches to treat obesity in preschoolers

Background

While obesity has been shown to be difficult to treat in school aged children and in adolescence, promising results have been detected for children who started treatment in early childhood. Yet knowledge on the effectiveness of structured early childhood obesity treatment programs is limited, preventing the widespread implementation of such programs. The main objective of this study is to evaluate the effectiveness of early treatment of childhood obesity with respect to treatment focus (parenting practices or lifestyle), length and intensity. The study will also examine the influence of gender, age, parental weight status, parenting practices, child behavior as well as parents’ socioeconomic status and child and parental psychosocial health on children’s weight status.

Methods/design

This is a parallel open label randomized controlled trial assessing two different behavioral treatment approaches offered in three conditions to families with children aged 4–6 years in Stockholm County, Sweden. Children (n = 180) identified as obese will be referred from primary child health care, school health care, and from outpatient pediatric clinics, and randomized to: 1) a standard treatment with focus on lifestyle, provided within the current healthcare system (n = 90); 2) a 10-session, 1.5 h/week group treatment with focus on parenting (n = 45); or 3) the same group treatment as 2) with additional follow-up sessions (n = 45). The primary study outcome is change in children’s body mass index standard deviation score (BMI SDS) one year post-baseline. Secondary outcomes include changes in children’s waist circumference, metabolic health, lifestyle patterns (Food Frequency Questionnaire), obesity-related child behaviors (Child Eating Behavior Questionnaire and Lifestyle Behavior Checklist, Problem Scale), parents’ general and feeding parenting practices (Communicating with Children and Child Feeding Questionnaire) and lifestyle-specific self-efficacy (Lifestyle Behavior Checklist, Confidence Scale), family functioning (Family Assessment Device), child and parental psychosocial health (Child Behavior Checklist and Beck’s Depression Inventory II).

Discussion

This study will facilitate a close examination of key components of treatment for obesity during early childhood and mechanisms of change. Results from this study will lead to better healthcare options for obesity treatment during early childhood and ultimately to the prevention of obesity later in life.

Health in overweight children: 2-year follow-up of Finnmark Activity School--a randomised trial

OBJECTIVE

To compare a comprehensive lifestyle intervention for overweight children performed in groups of families with a conventional single-family treatment. Two-year follow-up data on anthropometric and psychological outcome are presented.

DESIGN

Overweight and obese children aged 6-12 years with body mass index (BMI) corresponding to ≥27.5 kg/m(2) in adults were randomised to multiple-family (n=48) or single-family intervention (n=49) in a parallel design. Multiple-family intervention comprised an inpatient programme with other families and a multidisciplinary team, follow-up visits in their hometown, weekly physical activity and a family camp. Single-family intervention included counselling by paediatric nurse, paediatric consultant and nutritionist at the hospital and follow-up by a community public health nurse. Primary outcome measures were change in BMI kg/m(2) and BMI SD score after 2 years.

RESULTS

BMI increased by 1.29 kg/m(2) in the multiple-family intervention compared with 2.02 kg/m(2) in the single-family intervention (p=0.075). BMI SD score decreased by 0.20 units in the multiple-family group and 0.08 units in the single-family intervention group (p=0.046). A between-group difference of 2.4 cm in waist circumference (p=0.038) was detected. Pooled data from both treatment groups showed a significant decrease in BMI SD score of 0.14 units and a significant decrease in parent-reported and self-reported Strength and Difficulty Questionnaire total score of 1.9 units.

CONCLUSIONS

Two-year outcome showed no between-group difference in BMI. A small between-group effect in BMI SD score and waist circumference favouring multiple-family intervention was detected. Pooled data showed an overall improvement in psychological outcome measures and BMI SD score.

Recent Updates on the Efficacy of Group Based Treatments for Pediatric Obesity

BACKGROUND

There is limited research on optimal treatment formats for childhood obesity. Group-based interventions are popular, but it is unclear whether outcomes can be obtained without an additional individual component.

AIM

To examine statistically and clinically significant outcomes of recent group-based and mixed-format (group + Individual) pediatric obesity interventions.

METHODS

Effect sizes and magnitudes of weight change were calculated for studies published between January 2013 and September 2014.

RESULTS

Approximately half of the group-based studies reviewed produced significant results compared to control, and effect sizes were small. Mixed-format studies were less likely to include a control group, but those that did evidenced medium to large effects. Magnitudes of weight change post-intervention were generally greater in mixed-format studies than group-only studies.

CONCLUSIONS

Recent studies in pediatric obesity interventions suggest including an individual component in a group-based intervention produces optimal outcomes. Future research should directly compare group-only and mixed formats to confirm this observation.

Lifestyle therapy for the treatment of youth with type 2 diabetes

Type 2 diabetes (T2D) in youth is a relatively novel condition facing paediatric health care providers. Few experimental trials exist to guide clinical management in this population. Supporting and prescribing modifiable lifestyle behaviours is cornerstone in the management of T2D in adults. Clinical trials in obese adolescents suggest that intensive lifestyle interventions that include both dietary changes and increased physical activity elicit clinically meaningful reductions in weight and improve cardiovascular risk profiles. Observational studies in youth with T2D suggest that better diet quality and increased physical activity are associated with better metabolic control; however, the limited experimental data available does not support these observations. Trials evaluating lifestyle monotherapy for the treatment of hyperglycaemia in youth with T2D do not exist, and the only study evaluating combined lifestyle and pharmacologic therapy did not show additional benefit over pharmacologic treatment with metformin alone. Physiological and psychosocial differences between youth and adults with T2D likely contribute to the differences in the effectiveness of lifestyle therapy for improving glycaemic control. The current review describes these topics in detail and provides recommendations for paediatric health care providers for the promotion of lifestyle therapy for the management of hyperglycaemia and cardiovascular risk factors for youth with T2DM.
