Patient navigator programmes for children and adolescents with chronic diseases

BACKGROUND

Despite a substantial global improvement in infant and child mortality from communicable diseases since the early 1990s there is now a growing burden of chronic disease in children and adolescents worldwide, mimicking the trend seen in the adult population. Chronic diseases in children and adolescents can affect all aspects of their well-being and function with these burdens and their health-related consequences often carried into adulthood. Up to one third of disability-adjusted life years for children and adolescents globally are a result of chronic disease. This has profound implications for the broader family unit, communities, and health systems in which these children and young people reside. Models of chronic care delivery for children and adolescents with chronic disease have traditionally been adapted from adult models. There is a growing recognition that children and adolescents with chronic diseases have a unique set of healthcare needs. Their needs extend beyond disease education and management appropriate to the developmental stage of the child, to encompass psychological well-being for the entire family and a holistic care approach focusing on the social determinants of health. It is for this reason that patient navigators have been proposed as a potential intervention to help fulfil this critical healthcare gap. Patient navigators are trained medical or non-medical personnel (e.g. lay health workers, community health workers, nurses, or people with lived experience) who provide guidance for the patients (and their primary caregivers) as they move through complex (and often bewildering) medical and social systems. The navigator may deliver education, help to co-ordinate patient care, be an advocate for the patient (and their primary caregivers), or combinations of these. Patient navigators can assist people with a chronic illness (especially those who are vulnerable or from a marginalised population, or both) to better understand their diagnoses, treatment options, and available resources. As there is considerable variation in the purpose, design, and target population of patient navigator programmes, there is a need to systematically review and summarise the existing literature on the effectiveness of navigator programmes in children and young adults with chronic disease.

OBJECTIVES

To assess the effectiveness of patient navigator programmes in children and adolescents with chronic diseases.

SEARCH METHODS

We searched the Cochrane Library and Epistemonikos up to 20 January 2023 for related systematic reviews using search terms relevant to this review. We searched CENTRAL, MEDLINE, Embase, CINAHL EBSCO, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov for primary studies.

SELECTION CRITERIA

We included randomised controlled trials reporting the effect of patient navigator interventions on children and adolescents (aged 18 years or younger) with any chronic disease in hospital or community settings. Two review authors independently assessed the retrieved titles and abstracts, and where necessary, the full text to identify studies that satisfied the inclusion criteria.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data using a standard data extraction form. We used a random-effects model to perform a quantitative synthesis of the data. We used the I² statistic to measure heterogeneity amongst the studies in each analysis. We indicated summary estimates as mean differences (MD), where studies used the same scale, or standardised mean differences (SMD), where studies used different scales, with 95% confidence intervals (CI). We used subgroup and univariate meta-regression to assess reasons for between-study differences. We used the Cochrane RoB 1 tool to assess the methodological quality of the included studies. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included 17 studies (2895 randomised participants). All studies compared patient navigators with standard care. Most studies were at unclear or high risk of bias. Meta-analysis was undertaken only for those studies that had the same duration of patient navigator intervention and follow-up/reporting of outcome measures. The evidence is very uncertain about the effects of patient navigator programmes compared with standard care on self-reported quality of life of children with chronic illness (SMD 0.63, 95% CI -0.20 to 1.47; I2 = 96%; 4 studies, 671 participants; very low-certainty evidence); parent proxy-reported quality of life (SMD 0.09, 95% CI -2.21 to 2.40; I2 = 99%; 2 studies, 309 participants; very low-certainty evidence); or parents' or caregivers' quality of life (SMD -1.98, 95% CI -4.13 to 0.17; I2 = 99%; 3 studies, 757 participants; very low-certainty evidence). It is uncertain whether duration of patient navigator intervention accounts for any of the variances in the changes in quality of life. The evidence is very uncertain about the effects of patient navigator programmes compared with standard care on the number of hospital admissions (MD -0.05, 95% CI -0.34 to 0.23; I2 = 99%; 2 studies, 381 participants; very low-certainty evidence) and the number of presentations to the emergency department (MD 0.06, 95% CI -0.23 to 0.34; I2 = 98%; 2 studies, 381 participants; very low-certainty evidence). Furthermore, it is unclear whether patient navigator programmes reduce the number of missed school days as data were sparse (2 studies, 301 participants). Four studies (629 participants) reported data on resource use. However, given the variation in units of analysis used, meta-analysis was not possible (very low-certainty evidence). All studies reported cost savings or quality-adjusted life year improvement (or both) in the patient navigation arm. No studies reported on adverse events (specifically, abuse of any type against the navigator, the patient, or their family members).

AUTHORS' CONCLUSIONS

There is insufficient evidence at present to support the use of patient navigator programmes for children and adolescents with chronic diseases. The current evidence is based on limited data with very low-certainty evidence. Further studies are likely to significantly change these results.

The role and impact of community health workers in childhood obesity interventions: a systematic review and meta-analysis

Childhood obesity increases the risk for poor health during childhood, as well as for adult obesity and its associated comorbidities. Children from racial/ethnic minority groups or who live in poverty experience elevated rates of obesity. One potential method for reducing childhood obesity disparities is to involve community health workers (frontline public health workers who are trusted members of and/or have an unusually close understanding of the community served). The purpose of this systematic review and meta-analysis was to explore the role and effectiveness of community health workers in childhood obesity interventions. Eleven studies met inclusion criteria, of which nine were eligible for inclusion in the meta-analysis. Results demonstrated that community health workers played various roles in childhood obesity interventions in the home, clinic, school, and community setting. Interventions focused primarily on children from underserved populations. Meta-analytic findings demonstrated a small but significant impact on BMIz and BMI percentile (BMIz [7 studies]: -0.08, 95% CI: -0.15, -0.01, p = 0.03, I2  = 39.4%; BMI percentile [2 studies]: -0.25, 95% CI: -0.38, -0.11, p < 0.01, I2  = 0%). Findings from this review demonstrate that partnering with community health workers may be an important strategy for reducing childhood obesity disparities and advancing health equity.

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.

Systematic review of paediatric weight management interventions delivered in the home setting

To increase their accessibility, paediatric weight management interventions are increasingly designed to be delivered in the home setting by trained staff. This systematic review summarizes the available evidence for interventions featuring home visitation and identifies key gaps in the literature. PubMed, CINAHL, Cochrane and PsycINFO were searched for intervention studies that reported change in objectively measured adiposity outcomes in youth ages 2-18 years. Studies published between 1 January 1995 and 12 February 2016 were analysed. Of 15 eligible studies, nine reported that interventions with home visitation were either superior to a control/comparison condition or achieved significant within-subjects reductions in adiposity. Interventions in which professional staff (e.g. dietitians and exercise trainers) conducted home visits tended to be more efficacious than those delivered by paraprofessional or community-based staff, as were interventions with more frequent contact. Most studies were judged to have low or unclear risk of bias across various domains. As most studies compared interventions with home visits with less intensive and qualitatively different approaches, it remains unclear whether home visitation per se enhances weight loss efficacy. Overall, paediatric weight management interventions that feature home visitation are promising, but the incremental benefit of the home visitation treatment modality remains to be rigorously evaluated. © 2016 World Obesity.

Social influence in childhood obesity interventions: a systematic review

The objective of this study is to understand the pathways through which social influence at the family level moderates the impact of childhood obesity interventions. We conducted a systematic review of obesity interventions in which parents' behaviours are targeted to change children's obesity outcomes, because of the potential social and environmental influence of parents on the nutrition and physical activity behaviours of children. PubMed (1966-2013) and the Web of Science (1900-2013) were searched, and 32 studies satisfied our inclusion criteria. Results for existing mechanisms that moderate parents' influence on children's behaviour are discussed, and a causal pathway diagram is developed to map out social influence mechanisms that affect childhood obesity. We provide health professionals and researchers with recommendations for leveraging family-based social influence mechanisms to increase the efficacy of obesity intervention programmes. © 2016 World Obesity.

Effects of parent-only childhood obesity prevention programs on BMIz and body image in rural preteens

This experiment compared body image (BI) and BMI changes resulting from two parent-only obesity prevention interventions aimed at 8-12 year olds. Parents in the experimental intervention attended ten face-to-face educational sessions, while parents in the minimal (control) intervention received similar mailed information. Parent-child dyads (N=150) were semi-randomly assigned to intervention groups. Children were assessed before, after, and 6 months following the interventions; children did not attend experimental intervention sessions. Child BI assessments included weight and size perception, weight management goals, body esteem, and appearance attitudes. Significant effects included small decreases in BMIz scores and overweight dissatisfaction, as well as improvements in aspects of body esteem and appearance attitudes. Some BI effects were gender-specific. Decreases in overweight dissatisfaction were greater following the experimental treatment. Neither treatment reduced body size misperception. Thus, parent-only obesity prevention interventions can reduce body weight and body image concerns among rural preteens.

Parent-only interventions for childhood overweight or obesity in children aged 5 to 11 years

BACKGROUND

Child and adolescent overweight and obesity have increased globally, and are associated with short- and long-term health consequences.

OBJECTIVES

To assess the efficacy of diet, physical activity and behavioural interventions delivered to parents only for the treatment of overweight and obesity in children aged 5 to 11 years.

SEARCH METHODS

We performed a systematic literature search of databases including the Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and LILACS as well trial registers. We checked references of identified trials and systematic reviews. We applied no language restrictions. The date of the last search was March 2015 for all databases.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) of diet, physical activity and behavioural interventions delivered to parents only for treating overweight or obesity in children aged 5 to 11 years.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for risk of bias and evaluated overall study quality using the GRADE instrument. Where necessary, we contacted authors for additional information.

MAIN RESULTS

We included 20 RCTs, including 3057 participants. The number of participants ranged per trial between 15 and 645. Follow-up ranged between 24 weeks and two years. Eighteen trials were parallel RCTs and two were cluster RCTs. Twelve RCTs had two comparisons and eight RCTs had three comparisons. The interventions varied widely; the duration, content, delivery and follow-up of the interventions were heterogeneous. The comparators also differed. This review categorised the comparisons into four groups: parent-only versus parent-child, parent-only versus waiting list controls, parent-only versus minimal contact interventions and parent-only versus other parent-only interventions.Trial quality was generally low with a large proportion of trials rated as high risk of bias on individual risk of bias criteria.In trials comparing a parent-only intervention with a parent-child intervention, the body mass index (BMI) z score change showed a mean difference (MD) at the longest follow-up period (10 to 24 months) of -0.04 (95% confidence interval (CI) -0.15 to 0.08); P = 0.56; 267 participants; 3 trials; low quality evidence. In trials comparing a parent-only intervention with a waiting list control, the BMI z score change in favour of the parent-only intervention at the longest follow-up period (10-12 months) had an MD of -0.10 (95% CI -0.19 to -0.01); P = 0.04; 136 participants; 2 trials; low quality evidence. BMI z score change of parent-only interventions when compared with minimal contact control interventions at the longest follow-up period (9 to 12 months) showed an MD of 0.01 (95% CI -0.07 to 0.09); P = 0.81; 165 participants; 1 trial; low quality evidence. There were few similarities between interventions and comparators across the included trials in the parent-only intervention versus other parent-only interventions and we did not pool these data. Generally, these trials did not show substantial differences between their respective parent-only groups on BMI outcomes.Other outcomes such as behavioural measures, parent-child relationships and health-related quality of life were reported inconsistently. Adverse effects of the interventions were generally not reported, two trials stated that there were no serious adverse effects. No trials reported on all-cause mortality, morbidity or socioeconomic effects.All results need to be interpreted cautiously because of their low quality, the heterogeneous interventions and comparators, and the high rates of non-completion.

AUTHORS' CONCLUSIONS

Parent-only interventions may be an effective treatment option for overweight or obese children aged 5 to 11 years when compared with waiting list controls. Parent-only interventions had similar effects compared with parent-child interventions and compared with those with minimal contact controls. However, the evidence is at present limited; some of the trials had a high risk of bias with loss to follow-up being a particular issue and there was a lack of evidence for several important outcomes. The systematic review has identified 10 ongoing trials that have a parent-only arm, which will contribute to future updates. These trials will improve the robustness of the analyses by type of comparator, and may permit subgroup analysis by intervention component and the setting. Trial reports should provide adequate details about the interventions to be replicated by others. There is a need to conduct and report cost-effectiveness analyses in future trials in order to establish whether parent-only interventions are more cost-effective than parent-child interventions.

Carer-led health interventions to monitor, promote and improve the health of adults with intellectual disabilities in the community: a systematic review

Using carers to help assess, monitor, or promote health in people with intellectual disabilities (ID) may be one way of improving health outcomes in a population that experiences significant health inequalities. This paper provides a review of carer-led health interventions in various populations and healthcare settings, in order to investigate potential roles for carers in ID health care. We used rapid review methodology, using the Scopus database, citation tracking and input from ID healthcare professionals to identify relevant research. 24 studies were included in the final review. For people with ID, the only existing interventions found were carer-completed health diaries which, while being well received, failed to improve health outcomes. Studies in non-ID populations show that carers can successfully deliver screening procedures, health promotion interventions and interventions to improve coping skills, pain management and cognitive functioning. While such examples provide a useful starting point for the development of future carer-led health interventions for people with ID, the paucity of research in this area means that the most appropriate means of engaging carers in a way that will reliably impact on health outcomes in this population remains, as yet, unknown.

School based interventions versus family based interventions in the treatment of childhood obesity- a systematic review

BACKGROUND

The prevalence of childhood obesity, which has seen a rapid increase over the last decade, is now considered a major public health problem. Current treatment options are based on the two important frameworks of school- and family-based interventions; however, most research has yet to compare the two frameworks in the treatment of childhood obesity.The objective of this review is to compare the effectiveness of school-based intervention with family-based intervention in the treatment of childhood obesity.

METHODS

Databases such as Medline, Pub med, CINAHL, and Science Direct were used to execute the search for primary research papers according to inclusion criteria. The review included a randomised controlled trial and quasi-randomised controlled trials based on family- and school-based intervention frameworks on the treatment of childhood obesity.

RESULTS

The review identified 1231 articles of which 13 met the criteria. Out of the thirteen studies, eight were family-based interventions (n = 8) and five were school-based interventions (n = 5) with total participants (n = 2067). The participants were aged between 6 and 17 with the study duration ranging between one month and three years. Family-based interventions demonstrated effectiveness for children under the age of twelve and school-based intervention was most effective for those aged between 12 and 17 with differences for both long-term and short-term results.

CONCLUSIONS

The evidence shows that family- and school-based interventions have a considerable effect on treating childhood obesity. However, the effectiveness of the interventional frameworks depends on factors such as age, short- or long-term outcome, and methodological quality of the trials. Further research studies are required to determine the effectiveness of family- and school-based interventions using primary outcomes such as weight, BMI, percentage overweight and waist circumference in addition to the aforementioned factors.

Interventions with children and parents to improve physical activity and body mass index: a meta-analysis

OBJECTIVE

Examine the effect of interventions with parents and children on children's physical activity and body mass index (BMI).

DATA SOURCE

Computerized searches for intervention studies published between 1990 and 2011 used multiple ProQuest databases, including unpublished dissertations and theses to minimize publication bias.

STUDY INCLUSION AND EXCLUSION CRITERIA

English-language, intervention-testing studies of children, parents, or families with outcomes of physical activity or BMI were retrieved from peer-reviewed journals, dissertations, and theses. Eliminated studies had no control or comparison group; had no continuous outcome variable; had no physical activity/exercise and/or BMI as outcomes; or had incomplete statistics necessary for meta-analysis (means, standard deviations, or confidence intervals).

DATA EXTRACTION

Twenty-one studies met inclusion criteria. Quality criteria were control group, objective outcome variable measure, clarity of variable definitions, and number and reason for subject withdrawal.

DATA SYNTHESIS

Meta-analysis on the raw difference of means estimated mean weighted effect size (MWES) assessed dispersion of effects and computed a summary effect.

RESULTS

MWES for interventions with parents and children on physical activity (Z = 2.92; confidence interval [CI] = .09 to .48; p = .002) and on BMI for interventions with children alone (Z = -2.10; CI = -.16 to -.01; p = .02) was significant.

CONCLUSION

A significant effect on physical activity but not on BMI was found when interventions included both parents and their children.

School-based physical activity programs for promoting physical activity and fitness in children and adolescents aged 6 to 18

BACKGROUND

The World Health Organization (WHO) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese. In addition, WHO estimates that physical inactivity causes 10% to 16% of cases each of breast cancer, colon, and rectal cancers as well as type 2 diabetes, and 22% of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades.

OBJECTIVES

The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents.

SEARCH METHODS

The search strategy included searching several databases to October 2011. In addition, reference lists of included articles and background papers were reviewed for potentially relevant studies, as well as references from relevant Cochrane reviews. Primary authors of included studies were contacted as needed for additional information.

SELECTION CRITERIA

To be included, the intervention had to be relevant to public health practice (focused on health promotion activities), not conducted by physicians, implemented, facilitated, or promoted by staff in local public health units, implemented in a school setting and aimed at increasing physical activity, included all school-attending children, and be implemented for a minimum of 12 weeks. In addition, the review was limited to randomized controlled trials and those that reported on outcomes for children and adolescents (aged 6 to 18 years). Primary outcomes included: rates of moderate to vigorous physical activity during the school day, time engaged in moderate to vigorous physical activity during the school day, and time spent watching television. Secondary outcomes related to physical health status measures including: systolic and diastolic blood pressure, blood cholesterol, body mass index (BMI), maximal oxygen uptake (VO2max), and pulse rate.

DATA COLLECTION AND ANALYSIS

Standardized tools were used by two independent reviewers to assess each study for relevance and for data extraction. In addition, each study was assessed for risk of bias as specified in the Cochrane Handbook for Systematic Reviews of Interventions. Where discrepancies existed, discussion occurred until consensus was reached. The results were summarized narratively due to wide variations in the populations, interventions evaluated, and outcomes measured.

MAIN RESULTS

In the original review, 13,841 records were identified and screened, 302 studies were assessed for eligibility, and 26 studies were included in the review. There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures. Specifically positive effects were observed for duration of physical activity, television viewing, VO2 max, and blood cholesterol. Generally, school-based interventions had little effect on physical activity rates, systolic and diastolic blood pressure, BMI, and pulse rate. At a minimum, a combination of printed educational materials and changes to the school curriculum that promote physical activity resulted in positive effects.In this update, given the addition of three new inclusion criteria (randomized design, all school-attending children invited to participate, minimum 12-week intervention) 12 of the original 26 studies were excluded. In addition, studies published between July 2007 and October 2011 evaluating the effectiveness of school-based physical interventions were identified and if relevant included. In total an additional 2378 titles were screened of which 285 unique studies were deemed potentially relevant. Of those 30 met all relevance criteria and have been included in this update. This update includes 44 studies and represents complete data for 36,593 study participants. Duration of interventions ranged from 12 weeks to six years.Generally, the majority of studies included in this update, despite being randomized controlled trials, are, at a minimum, at moderate risk of bias. The results therefore must be interpreted with caution. Few changes in outcomes were observed in this update with the exception of blood cholesterol and physical activity rates. For example blood cholesterol was no longer positively impacted upon by school-based physical activity interventions. However, there was some evidence to suggest that school-based physical activity interventions led to an improvement in the proportion of children who engaged in moderate to vigorous physical activity during school hours (odds ratio (OR) 2.74, 95% confidence interval (CI), 2.01 to 3.75). Improvements in physical activity rates were not observed in the original review. Children and adolescents exposed to the intervention also spent more time engaged in moderate to vigorous physical activity (with results across studies ranging from five to 45 min more), spent less time watching television (results range from five to 60 min less per day), and had improved VO2max (results across studies ranged from 1.6 to 3.7 mL/kg per min). However, the overall conclusions of this update do not differ significantly from those reported in the original review.

AUTHORS' CONCLUSIONS

The evidence suggests the ongoing implementation of school-based physical activity interventions at this time, given the positive effects on behavior and one physical health status measure. However, given these studies are at a minimum of moderate risk of bias, and the magnitude of effect is generally small, these results should be interpreted cautiously. Additional research on the long-term impact of these interventions is needed.

The role of lay health workers in pediatric chronic disease: a systematic review

BACKGROUND

Children with chronic diseases represent a high-cost and resource-intensive population of children. With continued gaps in chronic disease management and persistent fragmentation in the health care system, stakeholders are seeking new strategies to address the needs of these children.

OBJECTIVE

We sought to systematically assess the effectiveness of lay health worker interventions in improving health care utilization, symptom management, and family psychosocial outcomes for children with chronic conditions.

DATA SOURCE

PubMed, PsycINFO, and Web of Science (January 1961 to February 2013).

STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS

We developed a strategy to search citations to identify relevant articles. Search terms included randomized controlled trial (RCT), lay worker, parent mentor, peer mentor, peer educator, community health workers, community health aids, patient advocate, patient facilitator, patient liaison, promotoras(es), care ambassadors, patient navigator, and nonprofessional. Additional studies were identified by searching the reference lists of retrieved articles and contacting clinical experts. RCTs of lay health worker interventions for children with chronic conditions were included. Studies were restricted to those concentrated on children 0-18 years of age with chronic illnesses.

STUDY APPRAISAL AND SYNTHESIS METHODS

Abstracts were independently screened by 2 reviewers. Articles with relevant abstracts underwent full text review and were evaluated for inclusion criteria. A structured tool was used to abstract data from selected articles. Because of the heterogeneous interventions and outcomes, we did not conduct a meta-analysis.

RESULTS

The search yielded 736 unique articles, of which 17 met inclusion criteria. All interventions focused on specific conditions: asthma, type I diabetes, obesity, and failure to thrive. Interventions were heterogeneous in frequency, mode, and duration of interactions between lay health workers and subjects. Several interventions were multifaceted, including both one-on-one and group interactions. Improved outcomes most commonly reported were reduced urgent care use, decreases in symptoms, fewer missed work and school days, and increased parental quality of life. One study demonstrated that lay health worker interventions were cost-effective.

CONCLUSIONS

Lay health workers interventions in children with chronic conditions may lead to modest improvements in urgent care use, symptoms, and parental psychosocial outcomes. Such interventions may also be cost-effective. Future research should focus on interventions targeted toward other chronic conditions such as sickle cell disease or cystic fibrosis and medically complex children whose conditions are noncategorical.

The quality of dietary intake methodology and reporting in child and adolescent obesity intervention trials: a systematic review

Assessing dietary intake is important in evaluating childhood obesity intervention effectiveness. The purpose of this review was to evaluate the dietary intake methods and reporting in intervention studies that included a dietary component to treat overweight or obese children. A systematic review of studies published in the English language, between 1985 and August 2010 in health databases. The search identified 2,295 papers, of which 335 were retrieved and 31 met the inclusion criteria. Twenty-three studies reported energy intake as an outcome measure, 20 reported macronutrient intakes and 10 studies reported food intake outcomes. The most common dietary method employed was the food diary (n = 13), followed by 24-h recall (n = 5), food frequency questionnaire (FFQ) (n = 4) and dietary questionnaire (n = 4). The quality of the dietary intake methods reporting was rated as 'poor' in 15 studies (52%) and only 3 were rated as 'excellent'. The reporting quality of FFQs tended to be higher than food diaries/recalls. Deficiencies in the quality of dietary intake methods reporting in child obesity studies were identified. Use of a dietary intake methods reporting checklist is recommended. This will enable the quality of dietary intake results to be evaluated, and an increased ability to replicate study methodology by other researchers.

Effectiveness of lifestyle interventions in child obesity: systematic review with meta-analysis

BACKGROUND AND OBJECTIVES

The effects of lifestyle interventions on cardio-metabolic outcomes in overweight children have not been reviewed systematically. The objective of the study was to examine the impact of lifestyle interventions incorporating a dietary component on both weight change and cardio-metabolic risks in overweight/obese children.

METHODS

English-language articles from 1975 to 2010, available from 7 databases, were used as data sources. Two independent reviewers assessed articles against the following eligibility criteria: randomized controlled trial, participants overweight/obese and ≤18 years, comparing lifestyle interventions to no treatment/wait-list control, usual care, or written education materials. Study quality was critically appraised by 2 reviewers using established criteria; Review Manager 5.1 was used for meta-analyses.

RESULTS

Of 38 eligible studies, 33 had complete data for meta-analysis on weight change; 15 reported serum lipids, fasting insulin, or blood pressure. Lifestyle interventions produced significant weight loss compared with no-treatment control conditions: BMI (-1.25kg/m(2), 95% confidence interval [CI] -2.18 to -0.32) and BMI z score (-0.10, 95% CI -0.18 to -0.02). Studies comparing lifestyle interventions to usual care also resulted in significant immediate (-1.30kg/m(2), 95% CI -1.58 to -1.03) and posttreatment effects (-0.92 kg/m(2), 95% CI -1.31 to -0.54) on BMI up to 1 year from baseline. Lifestyle interventions led to significant improvements in low-density lipoprotein cholesterol (-0.30 mmol/L, 95% CI -0.45 to -0.15), triglycerides (-0.15 mmol/L, 95% CI -0.24 to -0.07), fasting insulin (-55.1 pmol/L, 95% CI -71.2 to -39.1) and blood pressure up to 1 year from baseline. No differences were found for high-density lipoprotein cholesterol.

CONCLUSIONS

Lifestyle interventions can lead to improvements in weight and cardio-metabolic outcomes. Further research is needed to determine the optimal length, intensity, and long-term effectiveness of lifestyle interventions.
