Studies comparing lifestyle interventions to usual care also resulted in significant immediate (−1.30kg/m², 95% CI −1.58 to −1.03) and posttreatment effects (−0.92 kg/m², 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.]]> Sat 24 Mar 2018 08:25:25 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:14526 24.9 kg/m² prior to weight loss. 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 Search strategy: Published and unpublished studies in the English language from 1970 to January 2012 were identified from six electronic databases.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://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12865 Sat 24 Mar 2018 08:14:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12862 Sat 24 Mar 2018 08:14:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16799 Mon 22 Jul 2024 11:16:08 AEST ]]>
