Stunting is a chronic condition of stunted growth due to long-term malnutrition and manifestations. In Indonesia, since 2017, toddlers stunted by 29,6%, and in 2018 increased to 30,8%. This study aims to determine the relationship of infectious diseases, initiation of early breastfeeding, history of exclusive breastfeeding, LBW, and first marriage with stunting. The method used in this study was observational analytic with a cross-sectional study approach, with a chi-square test and fisher's exact test population of 620 people, with a sample of 124 toddlers with purposive sampling technique. The results showed that there was a relationship between early breastfeeding initiation (p=0,014) exclusive breastfeeding (p=0,001), and was not the relationship between LBW (p=0,172) with the occurrence of stunting in the Tamalate Community Health Center in Makassar. In conclusion, there is no correlation between infectious disease and LBW with the incidence of stunting, and there is a relationship between early breastfeeding, exclusive breastfeeding, with stunting. It is recommended to mothers to maintain the child's lifestyle and diet to avoid infectious diseases, give children early breastfeeding and exclusive breastfeeding, also reject early marriage so as not to give birth to a child with LBW and cause stunting.
