Stunting is a condition where a person has a height that is not in accordance with their age. The stunting condition in Buton Tengah Regency is one of the highest in Southeast Sulawesi Province. To find out the extent of the implementation of the stunting reduction program in Buton Tengah Regency, it is necessary to analyze the effectiveness of the stunting program with a decrease in the incidence of stunting in Buton Tengah Regency in 2023. This study is a non-experimental descriptive study by looking at the effectiveness of the stunting program with a decrease in the prevalence of stunting in Buton Tengah Regency in 2023. The results of the analysis show that there was an increase in the prevalence of stunting from 2022 to 2023, namely from 1621 stunting incidents to 1805 incidents. This shows that the stunting program in Buton Tengah Regency has not been effective in reducing the incidence of stunting as a whole in Buton Tengah Regency. However, the stunting program has been effective in reducing the incidence of stunting in three sub-districts, namely Gu, East Mawasangka, and Sangia Wambulu Districts.
