Effectiveness of interventions to promote exercise adherence in people with overweight or obesity: a systematic review
Keywords: Overweight; obesity; physical exercises; adherence; accession.
The World Health Organization (WHO) projects that, in the next decade, half a billion people will be affected by grievances from physical inactivity. In this alarming scenario, overweight people are particularly affected due to a backbidding cycle. Thus, the more sedentary they become, the more they tend to gain weight, and the more weight they earn, the more they tend to physical inactivity. Given this problematization, this research aims to identify which interventions are effective for promoting adherence to exercise in people with overweight or obesity. The methodology employed for systematic review involves screening of adult, overweight or obesity studies, with outcomes related to adherence to physical exercise and interventions of at least 12 weeks and control group, being performed independently by two researchers. Data extraction and synthesis were also performed independently and the “Cochrane Risk of Bias” tool was used to evaluate the methodological bias of selected studies. Due to the heterogeneity of the data collected, meta-analysis was unfeasible. In the results, of the 1,827 articles initially identified in the screening, 17 were considered eligible. The analyzes revealed that group activities or supervised by trained instructors generate greater adherence to physical exercise in the target audience. Factors such as Body Mass Index (BMI), weekly frequency, session duration, intensity or type of intervention do not appear great influence on adherence. However, most studies had a risk of bias, from moderate to high. It was considered that the findings described in the results of the studies raised should not be interpreted as reliable, due to methodological limitations and absence of relevant information perceived in these research, compromising reliability. It concludes that these results should be interpreted with caution and that new more robust studies, with greater methodological rigor, should be performed. Thus, this research contributes to the understanding of adherence and adherence to exercise interventions in individuals with overweight or obesity, through the systematic review of the available scientific literature.
