Early childhood is a critical developmental stage where established dietary patterns can impact lifelong health outcomes. This study investigates dietary patterns and their relationships with sociodemographic factors among Malaysian preschoolers. A total of 643 preschoolers of Malay, Indian, Chinese and other ethnicities participating in South East Asian Nutrition Surveys (SEANUTS II) were included. Dietary intake was assessed using a single triple‐pass 24‐h dietary recall method. Dietary patterns were derived using principal component analysis and their association with sociodemographic factors was determined using complex sampling logistic regressions. Five dietary patterns were identified: "healthy eating," "wholegrains and starchy vegetables," "high salt and sugar," "Western food," and "sugary drinks and legumes". Having older siblings was inversely associated with a "healthy eating" pattern (adjusted OR: 0.54, 95% CI: 0.33–0.87). Malay ethnicity was associated with higher odds of adhering to the "high salt and sugar" pattern (adjusted OR: 4.12, 95% CI: 2.20–7.75). Meanwhile, children living in urban areas (adjusted OR: 1.76, 95% CI: 1.03–3.01), those from middle‐income families (adjusted OR: 3.20, 95% CI: 1.38–7.40) and whose fathers were overweight (adjusted OR: 2.79, 95% CI: 1.58–4.94) showed a higher association with "Western food" pattern. Conversely, children whose mothers had overweight were less likely to adhere to the "Western food" pattern (adjusted OR: 0.50, 95% CI: 0.30–0.83). Older age was significantly associated with a greater likelihood of the "sugary drinks and legumes" pattern (adjusted OR: 3.99, 95% CI: 1.75–9.06). There was no significant association between "wholegrains and starchy vegetables" pattern with sociodemographic characteristics (all p > 0.05). These findings suggest that ethnicity, age, residence area, having older siblings, parental weight status and household income level are associated with dietary patterns among multiethnic preschoolers in Malaysia. Thus, these sociodemographic characteristics should be considered when designing targeted dietary strategies and interventions for preschoolers. [ABSTRACT FROM AUTHOR]

Objective: This paper aims to report South East Asian Nutrition Surveys (SEANUTS) II Malaysia data on nutritional status, dietary intake and nutritional biomarkers of children aged 6 months to 12 years. Design: Cross-sectional survey conducted in 2019–2020. Setting: Multistage cluster sampling conducted in Central, Northern, Southern and East Coast regions of Peninsular Malaysia. Participants: 2989 children aged 0·5–12·9 years. Results: Prevalences of stunting, thinness, overweight and obesity among children aged 0·5–12·9 years were 8·9 %, 6·7 %, 9·2 % and 8·8 %, respectively. Among children below 5 years old, 11·4 % were underweight, 13·8 % had stunting and 6·2 % had wasting. Data on nutritional biomarkers showed that a small proportion of children aged 4–12 years had Fe (2·9 %) and vitamin A deficiencies (3·1 %). Prevalence of anaemia was distinctly different between children below 4 years old (40·3 %) and those aged 4 years and above (3·0 %). One-fourth of children (25·1 %) had vitamin D insufficiency, which was twice as prevalent in girls (35·2 % v. boys: 15·6 %). The majority of children did not meet the recommended dietary intake for Ca (79·4 %) and vitamin D (94·8 %). Conclusions: Data from SEANUTS II Malaysia confirmed that triple burden of malnutrition coexist among children in Peninsular Malaysia, with higher prevalence of overnutrition than undernutrition. Anaemia is highly prevalent among children below 4 years old, while vitamin D insufficiency is more prevalent among girls. Low intakes of dietary Ca and vitamin D are also of concern. These findings provide policymakers with useful and evidence-based data to formulate strategies that address the nutritional issues of Malaysian children. [ABSTRACT FROM AUTHOR]
