Socio-demographics, dietary diversity score, and nutritional status of children aged 2–5 years: A cross-sectional study of Indonesian coastal areas

Background Climate change has negatively impacted both food security and food diversity, including malnutrition (stunting, wasting, and underweight), especially among children in coastal areas. The dietary diversity score (DDS) is a good indicator used to assess the quality of food for children. This study aimed to investigate the association between socio-demographic characteristics, DDS, and nutritional status in children aged 2–5 years in the coastal area of Demak, Indonesia. Methods A cross-sectional study was conducted on 130 households with children aged 2–5 years living in the coastal area of Demak from April to July 2022. The socio-demographic characteristics were determined by interviewing the mother or child caregiver, followed by anthropometric measurements of the children. The DSS was calculated based on the 24-h food recall method. Descriptive statistics, independent samples t-test, and Chi-square were used for statistical analysis. Results The mean age of the subjects was 3.11 ± 0.93 years (girl 46.9% and boy 53.1%). Maternal education was significantly associated with children's DDS (P = 0.016). There was a significant association between the history of acute respiratory infection (ARI) and nutritional status based on HAZ (P = 0.023), and there was also a significant association between exclusive breastfeeding history and family type with nutritional status based on WHZ (P < 0.05). Conclusion The study indicated a significant association between socio-demographic factors (mother's education, ARI history, exclusive breastfeeding history, and family type) with DDS and children's nutritional status in Demak.
