In 2021, the prevalence of underweight cases in Indonesia is recorded at 17%, an increase of 0.7% compared to 16.3% in 2019. One of the risk factors of undernutrition especially in children is the early marriages of the parents. There is an increase in early marriages by 175 pairs in Madiun Regency, East Java in 2020. Anthropometric measurement is an important part of handling nutrition, growth, and development problems such as being underweight, stunted and wasted which is in line with the objectives of the Indonesia Sehat program in the Rencana Pembangunan Jangka Menengah Nasional (RPJMN) 2020-2024 plan, namely improving the health and nutritional status of children. This descriptive study focuses on the anthropometric results of children under five who performed routine examinations in the period of August 2022 in the integrated healthcare center or Posyandu of Kuwiran Village, Madiun Regency, East Java, Indonesia. This study obtained data from the integrated healthcare center records using total sampling, which obtained 41 subjects. The results indicate that there is a 17.07% prevalence of underweight, 19.51% stunted, and 12.2% wasted from 41 under-five children who performed routine monthly measurements and check-ups at the integrated healthcare center of Kuwiran Village, Madiun Regency in the period of August 2022. The monthly prevalence of underweight and wasted children in Kuwiran Village alone is higher than the annual prevalence of underweight and wasted children in the Madiun Regency, East Java Province in 2021. However, the monthly prevalence of stunted children is lower than that of stunted children in East Java and Indonesia as a whole.
