Prevalence and Correlates of Meeting Physical Activity and Screen Time Guidelines Among Children of English- and Non-English-Speaking Backgrounds in Australia.

Background: Limited evidence suggests inequality in the prevalence of physical activity and screen time for children of non-English-speaking backgrounds (NESB). However, factors associated with these behaviours are understudied. This study identified the prevalence and correlates of meeting guidelines (physical activity, screen time and combined) among children of English-speaking backgrounds (ESB) and NESB.

Methods: Participants were from the Mothers and their Children's Health Study, a sub-study of the Australian Longitudinal Study on Women's Health (1973-1978 cohort). Mothers provided information on physical activity and screen time behaviours of up to three children (aged 2-12 years). Age-specific Australian guidelines were used to classify children as meeting or not meeting physical activity and screen time guidelines. Those born in a non-English-speaking country or primarily speaking a non-English language at home were classified as 'NESB'. Multivariable-adjusted logistic regression analyses accounting for family-level clustering were used for analysis.

Results: Data were from 4143 children (mean age 7.3 ± 2.9 years, 6.7% NESB). Around 17% children of NESB met physical activity guidelines (vs. 25% ESB, p = 0.002), 63% met screen time guidelines (vs. 58% ESB, p = 0.150), and 9% met combined physical activity and screen time guidelines (vs. 15% ESB, p = 0.011). Increasing age was inversely associated with meeting physical activity guidelines among children of both backgrounds (OR [95%CI]: NESB 0.81 [0.69-0.95], ESB 0.85 [0.82-0.87]). Family-level correlates (maternal education and physical activity level) were associated with meeting physical activity, screen time or combined guidelines among children of ESB only. A screen device in the child's bedroom was inversely associated with all outcomes among children of ESB. Children of NESB with a large yard at home had higher odds of meeting physical activity (4.14 [1.72-10.00]) and combined guidelines (4.48 [1.61-12.41]).

Conclusions: Children of NESB were less likely to meet physical activity and combined guidelines. Interventions may need to be tailored based on ESB background, with children of NESB (particularly older children and those with limited outdoor space at home) being a higher priority for intervention. Future large-scale studies examining a broader range of potential correlates, including cultural factors, are warranted.
