Micronutrient deficiencies and stunting are known as a significant problem in most developing countries, including Indonesia. The objective of this study was to analyze the association between micronutrient deficiencies and stunting with socioeconomic status (SES) among Indonesian children aged 6–59 months. This cross-sectional study was part of the South East Asian Nutrition Surveys (SEANUTS). A total of 1008 Indonesian children were included in the study. Anemia, iron deficiency, vitamin A deficiency, vitamin D deficiency, and stunting were identified in this study. Structured questionnaires were used to measure SES. Differences between micronutrient parameters and anthropometric indicators with the SES groups were tested using one-way ANOVA with post-hoc test after adjusted for age, area resident (rural and urban), and sex. The highest prevalence of anemia, stunting, and severe stunting were found to be most significant in the lowest SES group at 45.6%, 29.3%, and 54.5%, respectively. Children from the lowest SES group had significantly lower means of Hb, ferritin, retinol, and HAZ. Severely stunted children had a significantly lower mean of Hb concentration compared to stunted and normal height children. Micronutrient deficiencies, except vitamin D, and stunting, were associated with low SES among Indonesian children aged 6–59 months.

Numerous studies have highlighted the rising prevalence of overweight and obesity. In recent years, these conditions have also been increasingly observed in children. One interesting aspect to explore is the micronutrient profile of overweight and obese children, whether they generally fall within sufficient ranges, excessive, or conversely, show signs of deficiency. This study aims to examine the micronutrient status, namely serum vitamin A, 25(OH)D, zinc, iron, and calcium in children under five years old with an overweight/obese nutritional status (WHZ > +2SD). The design of the study was cross-sectional using secondary data from Riskesdas 2018 and the following study in 2021. Serum was analysed for retinol, 25(OH)D, zinc, ferritin, and calcium levels, then categorized into vitamin A, vitamin D, zinc, iron, and calcium status, respectively. The subjects of the study were 539 children aged 7-59 months. Data analysis included bivariate and multivariate regression. The results showed 7.9% were overweight/obese. No significant difference was found for all micronutrient levels between overweight/obese and those with non-overweight status. Children with insufficient levels of vitamin D were significantly associated with overweight/obesity (p=0.014, aOR 4.516, 95% CI: 1.358–15.010). Furthermore, zinc and iron overall showed the highest deficiency number, recorded at 213 and 187 subjects respectively. Interestingly, about 10% of the children with these deficiencies were still categorized as overweight/obese.
