Studies were considered if the participants had existing co-morbidities associated with overweight and obesity; however, they were excluded if participants had major medical problems or psychological illness. Types of intervention(s): Weight loss maintenance intervention strategies considered eligible were manipulation of a specific dietary component including prescribed diets, guidelines, advice and/or support to adhere to a dietary prescription. Types of studies: Only randomized controlled trial study designs were considered. Types of outcomes: The primary outcome measures were weight change, body mass index change, waist circumference change and body fat change. Search strategy: Published and unpublished studies in the English language from 1970 to January 2012 were identified from six electronic databases. Methodological quality: Methodological quality was assessed by two independent reviewers using the standardized critical appraisal instrument from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. Data collection: Data were extracted using the JBI data extraction form for experimental studies and included participant characteristics, intervention characteristics, study retention rates, and weight outcomes (weight change; kg or %, body mass index, waist circumference). Data synthesis: The impact of interventions on weight outcomes was described in a narrative format within each group of studies. The effectiveness of weight loss maintenance interventions was also assessed using the criteria of maintenance of ≥5% of initial weight loss. When studies were sufficiently similar and results were reported as either changescores or final values, and presented as means with standard deviations, data were pooled in a meta-analysis. Results: Sixty-four articles representing 56 studies were included in this review. Twenty seven studies prescribed a diet intervention, 11 meal replacements, two re-feeding time and type, and 16 support delivery mode interventions. Of the 56 studies, only 14 reported significant results for weight loss maintenance (Diet n=6, Meal replacements, n=1, Re-feeding n=1, Support delivery mode n=6). Conclusions: Currently there are many weight loss maintenance interventions being trialed but few have been found to be effective at maintaining >5% of initial weight loss. Whether this is due to the intervention itself being ineffective or simply the lack of reporting of this outcome, it is clear that more studies are needed to address this issue.]]> Sat 24 Mar 2018 08:19:46 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:14527 18 years. Types of intervention(s)/phenomena of interest: Intervention programs were required to have a parental component, to target eating and/or exercise behaviors for the prevention or treatment of obesity, and child weight status reported. Types of studies: All intervention studies were included in the review including: randomized controlled trials (RCTs); non-randomized controlled trials, longitudinal studies, cohort (both retrospective and prospective), case control and time series studies which had been conducted in a community setting. Types of outcomes: This review considered studies that included overweight/obesity related outcomes, eating behavior outcomes, physical activity behaviour outcomes, and sedentary behavior outcomes and constructs. Search strategy: A literature search of community-based parent-centred intervention studies to promote nutrition and physical activity for the prevention and treatment and of childhood overweight and obesity was performed in eight electronic databases dating from 1975 to April 2009. Methodological quality: Studies were critically appraised for methodological quality using standardized tools. Data collection: Data was extracted by one reviewer using a standardized data extraction form developed by the researchers and checked for accuracy and consistency by a second reviewer. Data synthesis: Data in relation to setting, methodology, intervention components and effect on weight, dietary intake and physical activity was extracted, and described in a narrative synthesis. Where possible a meta-analysis was undertaken. Results: Of the home-based interventions, five of nine studies reported statistically significant changes in anthropometric outcomes post intervention. Of the 10 studies in the before and after school care setting, seven reported a significant decrease in a weight-related outcome post intervention, with only one reporting an increase. Conclusions: Results from the review support the after-school setting as the most promising for community intervention setting for targeting parents as agents of change within child obesity prevention and treatment programs.]]> Sat 24 Mar 2018 08:19:46 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:14522 Sat 24 Mar 2018 08:19:45 AEDT ]]>
