Evaluation of Physical Activity and Lifestyle Interventions Focused on School Children with Obesity Using Accelerometry: A Systematic Review and Meta-Analysis. Int J Environ Res Public Health. 2020 Aug 19;17(17):60311661-7827http://hdl.handle.net/10668/4013Despite the existence of global recommendations for physical activity and lifestyle to avoid childhood obesity, there are no specific recommendations for school-age children. The aim of this meta-analysis was to measure the effects of current interventions with a physical activity component on body mass index (BMI) Z-score and on the moderate and vigorous physical activity (MVPA) time, measured by accelerometry, and focused on children with obesity. Randomized controlled trial studies (RCTs) based on physical activity interventions focused on children with obesity (6 to 12 years old) from January 1991 to August 2018 were included. The post-intervention mean and standard deviation of the BMI Z-score and MVPA engaged time were extracted to calculate the results using random effects models. Of a total of 229 studies considered potentially eligible, only 10 RCTs met the inclusion criteria. There were improvements in the BMI Z-score for physical activity intervention groups, compared with non-intervention children in addition to a significant increase in time engaged in MVPA. In conclusion, interventions with a physical activity component in school-children with obesity seem to be effective at reducing BMI and producing an increase in time spent engaged in physical activity. Therefore, interventions based on physical activity should be considered one of the main strategies in treating childhood obesity.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/Active lifeAccelerometryChildExerciseSchoolsObesityAcelerometríaNiñoEjercicio físicoObesidadMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::AccelerometryMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Body Constitution::Body Weights and Measures::Body Mass IndexMedical Subject Headings::Persons::Persons::Age Groups::ChildMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Anthropology, Education, Sociology and Social Phenomena::Education::SchoolsMedical Subject Headings::Anthropology, Education, Sociology and Social Phenomena::Human Activities::ExerciseMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Psychology, Social::Life StyleMedical Subject Headings::Diseases::Nutritional and Metabolic Diseases::Nutrition Disorders::Overnutrition::Obesity::Pediatric ObesityMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Clinical Trials as Topic::Controlled Clinical Trials as Topic::Randomized Controlled Trials as Topicreview article32825085open access10.3390/ijerph171760311660-4601PMC7503305
