What childhood obesity prevention programmes work? A systematic review and meta-analysis

Previous reviews of childhood obesity prevention have focused largely on schools and findings have been inconsistent. Funded by the US Agency for Healthcare Research and Quality (AHRQ) and the National Institutes of Health, we systematically evaluated the effectiveness of childhood obesity prevention programmes conducted in high‐income countries and implemented in various settings. We searched MEDLINE®, Embase, PsycINFO, CINAHL®, ClinicalTrials.gov and the Cochrane Library from inception through 22 April 2013 for relevant studies, including randomized controlled trials, quasi‐experimental studies and natural experiments, targeting diet, physical activity or both, and conducted in children aged 2–18 in high‐income countries. Two reviewers independently abstracted the data. The strength of evidence (SOE) supporting interventions was graded for each study setting (e.g. home, school). Meta‐analyses were performed on studies judged sufficiently similar and appropriate to pool using random effect models. This paper reported our findings on various adiposity‐related outcomes. We identified 147 articles (139 intervention studies) of which 115 studies were primarily school based, although other settings could have been involved. Most were conducted in the United States and within the past decade. SOE was high for physical activity‐only interventions delivered in schools with home involvement or combined diet–physical activity interventions delivered in schools with both home and community components. SOE was moderate for school‐based interventions targeting either diet or physical activity, combined interventions delivered in schools with home or community components or combined interventions delivered in the community with a school component. SOE was low for combined interventions in childcare or home settings. Evidence was insufficient for other interventions. In conclusion, at least moderately strong evidence supports the effectiveness of school‐based interventions for preventing childhood obesity. More research is needed to evaluate programmes in other settings or of other design types, especially environmental, policy and consumer health informatics‐oriented interventions.

A systematic review of home-based childhood obesity prevention studies

BACKGROUND AND OBJECTIVES: Childhood obesity is a global epidemic. Despite emerging research about the role of the family and home on obesity risk behaviors, the evidence base for the effectiveness of home-based interventions on obesity prevention remains uncertain. The objective was to systematically review the effectiveness of home-based interventions on weight, intermediate (eg, diet and physical activity [PA]), and clinical outcomes. METHODS: We searched Medline, Embase, PsychInfo, CINAHL, clinicaltrials.gov, and the Cochrane Library from inception through August 11, 2012. We included experimental and natural experimental studies with ≥1-year follow-up reporting weight-related outcomes and targeting children at home. Two independent reviewers screened studies and extracted data. We graded the strength of the evidence supporting interventions targeting diet, PA, or both for obesity prevention. RESULTS: We identified 6 studies; 3 tested combined interventions (diet and PA), 1 used diet intervention, 1 combined intervention with primary care and consumer health informatics components, and 1 combined intervention with school and community components. Select combined interventions had beneficial effects on fruit/vegetable intake and sedentary behaviors. However, none of the 6 studies reported a significant effect on weight outcomes. Overall, the strength of evidence is low that combined home-based interventions effectively prevent obesity. The evidence is insufficient for conclusions about home-based diet interventions or interventions implemented at home in association with other settings. CONCLUSIONS: The strength of evidence is low to support the effectiveness of home-based child obesity prevention programs. Additional research is needed to test interventions in the home setting, particularly those incorporating parenting strategies and addressing environmental influences.

Chronic venous leg ulcer treatment: Future research needs

The prevalence and costs of chronic venous ulcer care in the US are increasing. The Johns Hopkins University Evidence‐Based Practice Center recently completed a systematic review of the comparative effectiveness of advanced wound dressings, antibiotics, and surgical management of chronic venous ulcers. Of 10,066 citations identified in the literature search, only 66 (0.06%) met our liberal inclusion criteria for providing evidence on the effectiveness of interventions for chronic venous ulcers. Based on review of those studies, members of our team and a panel of informed stakeholders identified important research gaps and methodological deficiencies and prioritized specific future research needs. Based on that review, we provide the results of our assessment of future research needs for chronic venous ulcer care. Advanced wound dressings were considered to have the highest priority for future research, followed by venous surgery and antibiotics. An imperative from our assessment is that future research evaluating interventions for chronic venous ulcers meet quality standards. In a time of increasing cost pressure, the wound care community needs to develop high‐quality evidence to justify the use of present and future therapeutic modalities.

Methods for Improving the Quality of Palliative Care Delivery: A Systematic Review

Background: The effectiveness for improving the outcomes across palliative care domains remains unclear. We conducted a systematic review of different types of quality improvement interventions relevant to palliative care. Methods: We searched PubMed, CINAHL, PsycINFO, and Cochrane for relevant articles published between 2000 and 2011. Results: A total of 10 randomized controlled trials and 7 nonrandomized controlled trials were included. Of the 5 studies using relay of clinical information, 1 reported significant improvement in patient quality of life. Of the 5 studies targeting education and self-management, 4 found significant improvements in quality of life or patient symptoms. Conclusion: A minority of quality improvement interventions have succeeded in improving the quality of palliative care delivery. More studies are needed on specific quality improvement types, including organizational change and multiple types of interventions.

A Systematic Review of Health Care Interventions for Pain in Patients With Advanced Cancer

Purpose: Poorly controlled pain is common in advanced cancer. The objective of this article was to synthesize the evidence on the effectiveness of pain-focused interventions in this population. Methods: We searched MEDLINE, CINAHL, PsycINFO, Cochrane, and DARE from 2000 through December 2011. We included prospective, controlled health care intervention studies in advanced cancer populations, focusing on pain. Results: Nineteen studies met the inclusion criteria; most focused on nurse-led patient-centered interventions. In all, 9 (47%) of the 19 studies found a significant effect on pain. The most common intervention type was patient/caregiver education, in 17 (89%) of 19 studies, 7 of which demonstrated a significant decrease in pain. Conclusions: We found moderate strength of evidence that pain in advanced cancer can be improved using health care interventions, particularly nurse-led patient-centered interventions.

Pediatric Emergency Department Return: A Literature Review of Risk Factors and Interventions.

Background and Objective Children discharged from emergency departments (EDs) are often at risk for ED return. The objective was to identify risk factors and interventions to mitigate or prevent ED return among this patient population. Methods Structured literature review of PubMed and clinicaltrials.gov was conducted to identify relevant studies. Inclusion criteria were studies evaluating ED returns by identifying risk factors and interventions in the pediatric population. Emergency department return was defined as returning to the ED within 1 year after initial visit. Abstract and full text articles were reviewed, and data were abstracted by 2 independent authors. Results A total of 963 articles were screened and yielded 42 potential relevant articles involving pediatric population. After full text review, a total of 12 articles were included in the final analysis (6 on risk factors and 6 on interventions). Risk factors for pediatric ED return included behavioral/psychiatric problems, younger age, acuity of illness, medical history of asthma, and social factors. Interventions included computer-generated instructions, postdischarge telephone coaching, ED-made appointments, case management, and home environment intervention. Emergency department–made appointments and postdischarge telephone coaching plus monetary incentive improved outpatient follow-up rate but not ED return. Home environment assessment coupled with case management reduced ED returns specifically among asthma patients. Conclusions Several patient and visit characteristics can help predict children at risk for ED return. Although some interventions are successful at improving postdischarge follow-up, most did not reduce ED returns.

Avoiding Weight Gain in Cardiometabolic Disease: A Systematic Review

Patients with cardiometabolic disease are at higher risk for obesity-related adverse effects. Even without weight loss, weight maintenance may be beneficial. We performed a systematic review to identify the effect of nonweight loss-focused lifestyle interventions in adults with cardiometabolic disease. We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify comparative studies of lifestyle interventions (self-management, diet, exercise, or their combination) without a weight loss focus in adults with or at risk for diabetes and cardiovascular disease. Weight, BMI, and waist circumference at ≥12 months were the primary outcomes. Of 24,870 citations, we included 12 trials (self-management, n = 2; diet, n = 2; exercise, n = 2; combination, n = 6) studying 4,206 participants. Self-management plus physical activity ± diet versus minimal/no intervention avoided meaningful weight (−0.65 to −1.3 kg) and BMI (−0.4 to −0.7 kg/m2) increases. Self-management and/or physical activity prevented meaningful waist circumference increases versus control (−2 to −4 cm). In patients with cardiometabolic disease, self-management plus exercise may prevent weight and BMI increases and self-management and/or exercise may prevent waist circumference increases versus minimal/no intervention. Future studies should confirm these findings and evaluate additional risk factors and clinical outcomes.
