Trends and determinants of minimum dietary diversity among children aged 6–23 months: a pooled analysis of Indonesia Demographic and Health Surveys from 2007 to 2017

OBJECTIVE: To examine minimum dietary diversity (MDD) trends and determinants among children aged 6–23 months. DESIGN: Secondary analysis of the Indonesia Demographic and Health Surveys (IDHS) between 2007 and 2017. The primary outcome was MDD, the consumption of at least five out of eight food groups (MDD-8). We included a total of 5015 (IDHS 2007), 5050 (IDHS 2007) and 4925 (IDHS 2017) children aged 6 to 23 months to estimate trends of MDD-8 and to identify factors associated with MDD-8. We used multiple logistic regression analysis adjusted for the complex sampling design to investigate the association between the study factors and MDD-8. SETTING: Indonesia. PARTICIPANT: A total of 14 990 children aged 6–23 months. RESULTS: Over the 10 years, the percentage of children who consumed a diversified diet was 53·1 % in 2007, 51·7 % in 2012 and 53·7 % in 2017. Multivariate analyses showed that older age children, higher maternal education, maternal weekly access to media, paternal non-agricultural occupation, history of at least four antenatal care visits and wealthier households were associated with the increased odds of MDD-8. Children living in rural areas, Sulawesi and Eastern Indonesia, were less likely to eat a diversified diet. CONCLUSIONS: The proportion of children meeting MDD-8 has stagnated in the last decade. Child, parental, health care, household and community factors are associated with MDD-8. Therefore, nutrition education programmes and behaviour change communication activities should target mothers and families from socio-economically and geographically disadvantaged populations.
