Background: There is little information about the diet, lifestyle and parental characteristics associated with habitual sugar-sweetened beverage (SSB) consumption in Asian children. The aim of the present study was to assess crosssectional associations between habitual SSB consumption and preschoolers' diet, physical activity, sedentary behaviour as well as parental and child characteristics in Malaysian preschoolers aged 3 to 6 y. Methods: A total of 590 preschoolers, comprising 317 boys and 273 girls were included. Pre-pilot parental questionnaires were used to assess diet, physical activity (PA) and sedentary behaviour practices and anthropometry was assessed in preschoolers and their parents. Results: Multiple logistic regression analyses showed that preschoolers with more frequent weekly intake of snacks [OR 2.7; 95% CI, 1.6-4.4; p < 0.001] and monthly fast food consumption [OR 3.5; 95% CI, 1.9-6.3; p < 0.001], were associated with higher SSB intake (≥5 days in a week), after adjustments of potential confounders. Preschoolers with higher daily fruit and vegetable intake had lower SSB intake [OR 0.4; 95% CI, 0.2-0.8; p = 0.011]. A positive association of higher weekly vigorous PA [OR 2.0; 95% CI, 1.1-3.7; p = 0.030] and daily screen-based practices [OR 2.0; 95% CI, 1.2-3.6; p < 0.001] on habitual SSBs intake was also substantiated. Conclusion: Multiple diet, physical activity and sedentary behaviour factors were significantly associated with SSB intake among Malaysian preschoolers. Continued effort is required to encourage healthier beverage choices, as well as healthy diet and active lifestyle practices among children during the critical early years of growth and development.
