Exercise-based interventions and C-reactive protein in overweight and obese youths: a meta-analysis of randomized controlled trials

Background:One of the most commonly measured markers of inflammation in clinical settings is C-reactive protein (CRP). The purpose of this meta-analysis was to examine the evidence for the effectiveness of physical exercise interventions on modifying the levels of serum CRP in children and adolescents with excess of weight. Methods: Two independent reviewers assessed articles from seven databases. Studies were limited to physical exercise interventions in children and adolescents diagnosed as overweight or obese, and including a comparison control group. Weighted mean difference (WMD) was calculated using random-effects model and potential moderators were explored (i.e., weight status, ages, duration of study, frequency of exercise per week, and duration of session). The heterogeneity of the studies was estimated using Cochran's Q-statistic and I 2 . results: Nine randomized controlled trials met the inclusion criteria (n = 427 youths). Overall, results suggest a nonsignificant trend toward a reduction CRP levels (WMD = −0.72 mg/l; 95% confidence interval: −1.52 to 0.08; P = 0.077). Also, there were not significant moderators of exercise effects on CRP. conclusion: These results suggest that exercise programs in children and adolescents not mitigate the inflammatory effects of excess weight, although there was a trend toward reduction. t he prevalence of obesity among children and adolescents has dramatically increased in recent decades (1). Several physiopathologic mechanisms linking obesity to cardiovascular risk have been described (2). Inflammation is considered an important pathogenic mechanism in both the initiation and progression of cardiovascular diseases (CVD) (3). One of the most commonly measured markers of inflammation in clinical settings is C-reactive protein (CRP) (4,5). Plasma levels of CRP have been reported to be a strong independent predictor of risk of future myocardial infarction, stroke, peripheral arterial disease, and vascular death among individuals without known CVD (4). On the other hand, obesity has been associated with elevated levels of CRP in both adults and children (6). Furthermore, elevated levels of inflammatory factors in childhood and adolescence have been shown to track into adulthood (7). Given the apparent importance of CRP among other inflammatory markers in the development of CVD morbidity and mortality, it is critical to determine those factors that may help to lower and maintain optimal levels of CRP (8).It is documented that physical activity has a role in preventing CVD (9), mediated, in part, by changes in inflammation. Recently, great attention has been focused on the response of inflammation to physical exercise. Several studies have not provided support for exercise intervention-induced reductions in CRP in adults (8,10) and children (11). A recent review, although concluding that assessing body composition distribution may assist in interpreting the effectiveness of interventions in improving circulating inflammatory markers in obese children (3), does not prov...

ImportanceAlthough benefits have been reported for most exercise modalities, the most effective exercise approaches for reducing insulin resistance in children and adolescents with excess weight and the optimal exercise dose remain unknown.ObjectiveTo compare exercise training modalities and their association with changes in insulin resistance markers among children and adolescents with excess weight and to establish the optimal exercise dose.Data SourcesFor this systematic review and network meta-analysis, 6 electronic databases (PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, and CINAHL) were searched for studies from inception to April 1, 2023.Study SelectionRandomized clinical trials (ie, randomized controlled trials and randomized trials without a control group) were included if they reported outcomes associated with aerobic training, resistance training, high-intensity interval training (HIIT), or a combination of these interventions.Data Extraction and SynthesisData extraction for this systematic review was conducted following a network meta-analysis extension of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. Effect sizes were calculated as the mean difference (MD) with 95% CI using random-effects inverse-variance models with the Hartung-Knapp-Sidik-Jonkman method. The hierarchy of competing interventions was defined using the surface under the cumulative ranking curve. The Cochrane Risk-of-Bias tool, version 2 (RoB2), was used to independently assess the risk of bias of the included studies. The certainty of evidence in consistent networks was assessed using the Grading of Recommendation, Assessment, Development and Evaluation approach. The study protocol was prospectively registered with PROSPERO. Data analyses were conducted between May and June 2023.Main Outcomes and MeasuresThe primary outcomes were fasting glucose, insulin, and homeostatic model assessment for insulin resistance (HOMA-IR).ResultsThis analysis included 55 studies with a total of 3051 children and adolescents (mean [SD] age, 13.5 [2.3] years; 1537 girls [50.4%] and 1514 boys [49.6%]). Exercise was associated with reductions in fasting insulin (MD, −4.38 μU/mL [95% CI, −5.94 to −2.82 μU/mL]) and HOMA-IR (MD, –0.87 [95% CI, –1.20 to –0.53]). A nonlinear association in both markers was observed, with a required minimal exercise dosage of approximately 900 to 1200 metabolic equivalent of task minutes per week, especially in children and adolescents with insulin resistance at baseline. Combination HIIT and resistance training and concurrent training were the most effective approaches for reducing insulin resistance markers. On average, the certainty of evidence varied from low to moderate.Conclusions and RelevanceThese findings underscore the role of exercise interventions in enhancing insulin resistance markers among children and adolescents with overweight and obesity. It is advisable to include resistance exercises alongside aerobic and HIIT programs for a minimum of two to three 60-minute sessions per week.
