Congratulations to former HALOite Dr. Bruno da Costa and HALO Research Scientist Dr. Jean-Philippe Chaput on their recent publication, “Associations between Sociodemographic, Dietary, and Substance Use Factors with Self-Reported 24-hour Movement Behaviors in a Sample of Brazilian Adolescents,” in the International Journal of Environmental Research and Public Health. Authors showed that sociodemographic, dietary, and substance use factors are associated with 24-hour movement behaviours in Brazilian adolescents (and some associations are type specific). Citation details and an abstract of the paper are below.

Bravo, Bruno and team!

Abstract

We aimed to identify sociodemographic, dietary, and substance use factors associated with self-reported sleep duration, physical activity (PA), and sedentary behavior (SB) indicators in a sample of Brazilian adolescents. Adolescents (n = 731, 51% female, mean age: 16.4 years) answered a questionnaire. The volume of total PA, sports, non-sports, total SB, leisure-time SB, involuntary SB, sleep duration, dietary behaviors, sociodemographic, and substance use indicators were self-reported. Multilevel linear models were fitted. Females engaged in less total PA, sports, total SB, and leisure-time SB, but in more involuntary SB than males. Age was positively associated with non-sports and involuntary SB. Socioeconomic status was positively associated with total PA. Adolescents who lived with the mother only practiced more sports compared to those living with two parents. Unprocessed food was positively associated with total PA and sports. Processed food was inversely associated with total PA and non-sports, and positively associated with total SB and leisure-time SB. Alcohol use was positively associated with total PA, and tobacco smoking was negatively associated with total PA. No associations were observed for sleep duration. In conclusion, sociodemographic, dietary, and substance use factors are associated with the 24 h movement behaviors among Brazilian adolescents, and some associations are type specific.
