This was a cross sectional survey in which bivariate correlation and simple linear regression were used to determine associations between self-reported components. One hundred fifteen dancers were queried, 91.3% of whom were female. The mean BMI was 19.6 ± 2.3 kg/m2. Two-thirds of dancers fell below the 50th percentile for age-adjusted BMI, and 30.4% fell below the 25th percentile. Better than 12% of dancers reported a history of anxiety, and 2.6% reported depression. Mean hours of sleep per night was 7.8 ± 0.9, with 58% of the dancers getting less than 8 hours of sleep per night. The mean total screen time for dancers was 3.4 ± 2.1 hours/day, which consisted of tablet and computer usage: 1.6 ± 1.1 hours/day; texting: 0.5 ± 1.1 hours/day; watching television: 1.2 ± 1.1 hours/day; and playing video games 1.2 ± 1.1 hours/ day. Total screen time was independently associated positively with BMI, explaining nearly 10% of the variability in BMI. Age, hours dancing per day, and hours of sleep per night were not independently associated with BMI. To summarize: screen time was associated with increased BMI in this young dancer cohort; the majority of dancers slept less than 8 hours per night; anticipatory guidance addressing media use and sleep hygiene in the adolescent dancer population is needed. | Permalink : | https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= |
