Introduction: Wasting is an acute form of under-nutrition. Frequent occurrence and long-term wasting can lead to stunting. Indonesia has one of the world's highest wasting prevalence of 12.1% and ranked the 4th highest for wasting globally in 2012. Methods: Data from Rand Corp Indonesia Family Life Survey for 2000, 2007 and 2014 were used to examine wasting trend, while data for 2000 and 2014 were used to determine the associated factors of wasting in infants aged 0-23 months. Data was analysed using SPSS. Logistic regression was used to predict the variables contributing to wasting. Results: Wasting prevalence in 2000, 2007 and 2014 were 12.0%, 11.2% and 10.1%, respectively. Birth weight correlated significantly with wasting prevalence in 2000 while in 2014, wasting prevalence correlated significantly with birth weight, birth length, poverty, and ownership of "Mother and Child Health Book". Logistic regression showed that birth weight was an important associated factor in 2000 and 2014, while ownership of "Mother and Child Health Book" was the only important associated factor of birth weight in 2014. Conclusion: The prevalence of wasting among young Indonesian children was lower in 2014 compared to 2000, but is still at a high level. Birth weight consistently remains the significant factor affecting wasting. It is important that the nutritional status of women be taken care of before and during pregnancy for optimal birth outcomes.

ntroduction: Stunting in childhood affects cognitive development and may increase the risk of non-communicable diseases in adulthood. Indonesia is the fifth largest contributor of stunting in the world, with a prevalence of 32.9% in children aged 0-2 years in 2013. This study aimed to determine the stunting trend and associated factors between 2000 and 2014. Methods: This study used data from Indonesia Family Life Surveys (IFLS) that have been conducted periodically since 1993. This study focused on households with children aged 0-23 months. Trend analysis used the IFLS data collected in 2000, 2007 and 2014, while bivariate analysis for determination of the different factors associated with stunting used IFLS data in 2000 and 2014. Results: Based on data from 1,263 children in 2000, 1,805 children in 2007, and 1,609 children in 2014, stunting prevalence slightly increased from 29.7% in 2000 to 32.6% in 2014. Significant associations between stunting and children's age, birth weight, mother's education, antenatal care, health sanitation and immunisation status were recorded in 2000. In 2014, stunting was significantly associated with children's age, birth weight, prelacteal food intake, ownership of Mother and Child Health Book and health sanitation status. Conclusion: Stunting in children below 2 years in Indonesia remains high, exceeding 30%. This study identified several contributing factors to stunting. Interventions to address these factors should be undertaken toward reducing stunting among young children in Indonesia.
