This observational study examined the changes in body weight, eating behaviors, physical activity, and basal metabolic rate among first-year university students. The results showed that female students are at risk of unfavorable changes in body composition, while male students are more prone to sedentary behaviors. Intervention measures targeting high intakes of saturated fat, sugars, and sodium are warranted in this vulnerable group.
Background: Students in the United States gain weight significantly during their first year of university, however limited data are available for Australian students. Methods: This 12-month observational study was conducted to monitor monthly body weight and composition, as well as quarterly eating behaviours, dietary intake, physical activity, sedentary behaviours, and basal metabolic rate changes amongst first-year Australian university students. Participants were first-year university students over 18 years. Results: Twenty-two first-year university students (5 males and 17 females) completed the study. Female students gained weight significantly at two, three, and four-months (+0.9 kg; +1.5 kg; +1.1 kg, p < 0.05). Female waist circumference (2.5 cm increase at three-months, p = 0.012), and body fat also increased (+0.9%, p = 0.026 at three-months). Intakes of sugar, saturated fat (both > 10% of total energy), and sodium exceeded recommended levels (> 2000 mg) at 12-months. Greater sedentary behaviours were observed amongst male students throughout the study (p < 0.05). Conclusions: Female students are at risk of unfavourable changes in body composition during the first year of university, while males are at risk of increased sedentary behaviours. High intakes of saturated fat, sugars, and sodium warrant future interventions in such a vulnerable group.
