Social inequalities in health‐related use of time in Australian adolescents

Abstract Objective: Young people's socioeconomic position and time use behaviours – including physical activity, sedentary behaviours, social engagement, sleep and cognitive activities – have been associated with health outcomes. This study aimed to describe how time use varies with household income in a representative sample of 9–16 year old Australians. Methods: A random sample of 2,071 9–16 year old Australian children provided household income data and four days’ use‐of‐time data. Average daily minutes spent in various types of activities were calculated. Kruskal‐Wallis and Mann Whitney U tests were used to compare time use across the income bands. Results: Higher income participants spent significantly more time playing sport (p<0.0001), including team sports (p=0.0005), and in cognitively demanding behaviours such as school routine (p<0.0001), doing homework (p<0.0001) and playing music (p=0.001) than their low‐income counterparts. Conversely, low‐income participants spent significantly more time watching television (p<0.001) and playing videogames (p
