Healthcare utilisation in overweight and obese children: a systematic review and meta-analysis.

ABSTRACT: OBJECTIVE:This systematic review and meta-analysis aims to systematically analyse the association of overweight and obesity with health service utilisation during childhood. DATA SOURCES:PubMed, MEDLINE, CINAHL, EMBASE and Web of Science. METHODS:Observational studies published up to May 2020 that assessed the impact of overweight and obesity on healthcare utilisation in children and adolescents were included. Studies were eligible for inclusion if the included participants were ?19 years of age. Findings from all included studies were summarised narratively. In addition, rate ratios (RRs) and 95% CIs were calculated in a meta-analysis on a subgroup of eligible studies. OUTCOME MEASURES:Included studies reported association of weight status with healthcare utilisation measures of outpatient visits, emergency department (ED) visits, general practitioner visits, hospital admissions and hospital length of stay. RESULTS:Thirty-three studies were included in the review. When synthesising the findings from all studies narratively, obesity and overweight were found to be positively associated with increased healthcare utilisation in children for all the outcome measures. Six studies reported sufficient data to meta-analyse association of weight with outpatient visits. Five studies were included in a separate meta-analysis for the outcome measure of ED visits. In comparison with normal-weight children, rates of ED (RR 1.34, 95%?CI 1.07 to 1.68) and outpatient visits (RR 1.11, 95%?CI 1.02 to 1.20) were significantly higher in obese children. The rates of ED and outpatient visits by overweight children were only slightly higher and non-significant compared with normal-weight children. CONCLUSIONS:Obesity in children is associated with increased healthcare utilisation. Future research should assess the impact of ethnicity and obesity-associated health conditions on increased healthcare utilisation in children with overweight and obesity.

Project description:BackgroundAuricular acupressure has been used for treating obesity, but inconsistent outcomes have been reported. Moreover, systematic reviews and meta-analyses have seldom addressed the effects of auricular acupressure and duration of treatment in overweight/obese individuals. This study reviewed research articles on auricular acupressure for weight reduction, analyzed the related effects on obesity, and explored the relationships between weight reduction and treatment duration, as well as outcome variables.MethodsWe searched PubMed, Cochrane Library, CINAHL, MEDLINE with Full Text, National Digital Library of Theses and Dissertation in Taiwan, and Airiti Library for articles up to July 4, 2018. Eight eligible trials were identified for qualitative synthesis, and one of them was excluded from quantitative synthesis. Inclusion criteria were as follows: intervention contained auricular acupressure, study subjects were overweight and/or obese, as defined by published authors, and the study design had 2 or more arms for comparison.ResultsPooled analysis of the 7 remaining studies revealed that auricular acupressure alone, or with diet and/or exercise, was effective for weight reduction, particularly for decreasing body weight (BW), body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), body fat mass (BFM), and body fat percentage (BFP), compared with no treatment, sham treatment, or use of surgical tape with diet and/or exercise. However, there was no effect on hip circumference. A 12-week acupressure intervention was associated with a larger effect on lowering BW and BMI compared with 4-, 6-, and 8-week interventions. The methodologic quality of trials included in the quantitative synthesis ranged from scores 2 to 6 based on the modified Jadad scale. Additionally, this meta-analysis combined studies that used different acupoints and outcomes evaluated at different timepoints, which may have been potential sources of bias.ConclusionThe study results indicate that auricular acupressure is effective for weight reduction. However, further vigorous studies that use double-blind randomized controlled design are needed to verify these findings. WC, WHR, BFP, or BFM should be used as obesity-related parameters in weight reduction studies to detect changes in fat, muscle, and skeletal weight.

Project description:BackgroundOverweight and obesity are major public health problems in children and adolescents. The purpose of this study was to conduct a systematic review with meta-analysis to determine the effects of exercise (aerobic, strength or both) on body mass index (BMI) z-score in overweight and obese children and adolescents.MethodsStudies were included if they were randomized controlled exercise intervention trials ? 4 weeks in overweight and obese children and adolescents 2 to 18 years of age, published in any language between 1990-2012 and in which data were available for BMI z-score. Studies were retrieved by searching eleven electronic databases, cross-referencing and expert review. Two authors (GAK, KSK) selected and abstracted data. Bias was assessed using the Cochrane Risk of Bias Assessment Instrument. Exercise minus control group changes were calculated from each study and weighted by the inverse of the variance. All results were pooled using a random-effects model with non-overlapping 95% confidence intervals (CI) considered statistically significant. Heterogeneity was assessed using Q and I2 while funnel plots and Egger's regression test were used to assess for small-study effects. Influence and cumulative meta-analysis were performed as well as moderator and meta-regression analyses.ResultsOf the 4,999 citations reviewed, 835 children and adolescents (456 exercise, 379 control) from 10 studies representing 21 groups (11 exercise, 10 control) were included. On average, exercise took place 4 x week for 43 minutes per session over 16 weeks. Overall, a statistically significant reduction equivalent to 3% was found for BMI z-score (?¯, -0.06, 95% CI, -0.09 to -0.03; Q = 24.9, p = 0.01; I(2)=59.8%). No small-study effects were observed and results remained statistically significant when each study was deleted from the model once. Based on cumulative meta-analysis, results have been statistically significant since 2009. None of the moderator or meta-regression analyses were statistically significant. The number-needed-to treat was 107 with an estimated 116,822 million obese US children and adolescents and approximately 1 million overweight and obese children and adolescents worldwide potentially improving their BMI z-score by participating in exercise.ConclusionsExercise improves BMI z-score in overweight and obese children and adolescents and should be recommended in this population group. However, a need exists for additional studies on this topic.

Project description:OBJECTIVES:Determine both the effects and hierarchy of effectiveness for exercise interventions (aerobic, strength training or both) on selected measures of adiposity (body mass index (BMI) in kg/m2, fat mass and per cent body fat) in overweight and obese children and adolescents. DESIGN:Network meta-analysis of randomised exercise intervention trials. SETTING:Any setting where a randomised trial could be conducted. PARTICIPANTS:Overweight and obese male and/or female children and adolescents 2-18 years of age. INTERVENTIONS:Randomised exercise intervention trials>4 weeks, published between 1 January 1973 and 22 August 2018, and which included direct and/or indirect evidence for aerobic, strength training or combined aerobic and strength training. PRIMARY OUTCOMES:Changes in BMI in kg/m2, fat mass and per cent body fat. RESULTS:Fifty-seven studies representing 127 groups (73 exercise, 54 control) and 2792 participants (1667 exercise, 1125 control) met the criteria for inclusion. Length of training ([Formula: see text] ± SD) averaged 14.1±6.2 weeks, frequency, 3.3±1.1 days per week and duration 42.0±21.0 min per session. Significant and clinically important reductions in BMI, fat mass and per cent body fat were observed in aerobic versus control comparisons (BMI, mean, 95% CI -1.0, 1.4 to -0.6; fat mass -2.1, -3.3 to -1.0 kg; per cent fat -1.5, -2.2 to -0.9%) and combined aerobic and strength versus control comparisons (BMI -0.7, -1.4 to -0.1; fat mass -2.5, -4.1 to -1.0 kg; per cent fat, -2.2, -3.2 to -1.2%). A significant reduction in per cent fat was also found for strength vs control comparisons (-1.3,-2.5 to -0.1%). Combined aerobic and strength training was ranked first for improving both fat mass (kg) and per cent body fat while aerobic exercise was ranked first for improving BMI. CONCLUSIONS:Aerobic and combined aerobic and strength training are associated with improvements in adiposity outcomes in overweight and obese children and adolescents.
