ObjectiveThe aim of this study is to compare the levels of physical activity and sedentary behaviours in children with obesity and normal weight through accelerometer measures, and analyze the family environment related to physical activity.DesignCase-control study.LocationA health center and colleges of the Community of Madrid.ParticipantsA total of 50 obese children between 8 and 12 years of age (P > 97) and their mothers were matched by age, sex and socioeconomic status of their parents (1: 1) with 50 children with normopeso (GN; P < 85).Main MeasurementsPhysical activity levels were measured by accelerometer (ActiGraph GT3X), levels of physical activity of the primary caregiver were measured through physical activity questionnaire (IPAQ) and the environment in relation to the physical activity was measured by the Home Environment Scale (HES-S).ResultsThe group GO showed less vigorous physical activity than their peers in the GN group. Vigorous physical activity in the GO group was associated with modeling and parental policies regarding physical activity. A multiple regression analysis revealed that 21% of the variance of weight status of children was explained by sex, vigorous physical activity and maternal body mass index.ConclusionsThe levels of vigorous physical activity and the family environment differ between children with obesity and normal weight. Therefore, it is important to continue working on the awareness of illness and the promotion of healthy habits from Primary Care and the school and institutional context.Copyright © 2018 The Authors.
