Abstract

Background: Meeting recommendations of physical activity (PA), sedentary behaviour (SB) and sleeping time (ST), have begun to be studied together in the 24-Hour Movement Guidelines for Children and Youth (24MGCY) developed in Canada, to try to explain, prevent and improve health indicators. The purpose of this study was to determine the prevalence of meeting recommendations of movement in 24-hrs considering their three components according to sociodemographic variables in preadolescents of the Carahue, Chile. Materials and methods: Cross-sectional study of 222 children from third to sixth grade in Carahue, Chile. PA, SB and ST were measured through self-report. Meeting 24MGCY has been defined as at doing least 60 min/day of moderate to vigorous PA (MVPA), ≤2 h/day of SB and 9 to 11 h/night of ST. Nutritional status, age, unhealthy diet and parental education were included as effect modifier covariates. The influence of these on meeting recommendations was determined through a stratified analysis, according to sex, in relation with covariates using chi-squared analysis and Fisher test. Results: The mean age of the sample was 10.2 age of years, of which 50.5% were boys. 64.0% of children were overweight or obese. The prevalence of children meeting 24MGCY was 3.2%. Children meeting MVPA+SB were 4.1%, MVPA+ST were 5.9% and, finally, the proportion of children meeting SB+ST was 14.9%. The highest prevalence of compliance to guidelines was for ST (53.2%), then SB (27.0%) and the lower prevalence of compliance was for PA (13.1%). Girls with mothers that completed primary education had significantly higher compliance with SB recommendation in relation to boys with mothers with the same level of education (75.0% vs 25.0%, p=0.044). Normal-weight girls showed significantly higher prevalence of compliance to SB recommendation than normal weight boys (70.0% vs 30.0%, p=0.031). Conclusion: An extremely low percent of Chilean children met the 24MGCY when comparing this results with international data. More initiatives to promote the increase of physical activity, reduction of sedentary behaviour and promotion of better sleep must be implemented, especially in low socioeconomic communities.
