Health behaviours of 17- to 19-year olds in North East England: assessing adherence to current recommendations for young people at the adolescent-adult boundary

Le résumé fourni par la source

AIMS: Late adolescence/young adulthood represents a transition to independence, with increasing control over health behaviours (HB). However, HB data of late adolescents are often reported in wide and inconsistent age brackets, making comparisons with age-targeted guidelines difficult. We aimed to characterise important HB (body composition, physical activity (PA), diet) of late adolescents from North East England. METHODS: A total of 145 17- to 19-year olds from the Gateshead Millennium Study birth cohort participated in 2017 to 2018. Measurements including height, weight, body fat, accelerometer-measured PA and sedentary behaviour, and 24-hour dietary recall were taken. Comparisons with current global age-appropriate recommendations were made for four variables: (1) 60 min moderate-vigorous intensity PA (MVPA)/day (age 17 years old) or 150 min MVPA/week (18- to 19-years old); (2) body fat (<25% for males, <30% for females); (3) free sugars <5% total energy intake; (4) five portions fruit and/or vegetables/day. RESULTS: Most recommendations were not met: MVPA averaged 37 min/day, 20% of 17-year olds met 60 min/d, and 55% of 18- to 19-year olds met 150 min/week. About 26.5% of participants had excess body fat. Daily fruit/vegetable consumption was 2.7 portions; 12% consumed '5-a-day' portions of fruit and/or vegetables, 13.5% consumed <5% energy from free sugars. Together, 43% of participants met 0/4, 44% met 1/4%, and 0% met 4/4 age-appropriate health recommendations. CONCLUSION: These novel empirical data reveal concerning HB in this population of late adolescents, suggesting targeted health messaging to improve HB is needed.
