Prediction Model for Underweight among Age Under-five Children in Community Health Center of Banjar

Abstract

In 2022, the prevalence of underweight children in South Kalimantan was higher than the national average, with Banjar District ranking third at 26.9%. Being underweight leads to impaired brain intelligence, decreased immunity, disrupted child growth and development, and affects human resources. This study aims to create a prediction model for underweight in children under five in Banjar District by identifying dominant influencing factors, including birth weight, birth length, history of infectious diseases, exclusive breastfeeding, immunization completeness, regular visits to integrated health center (IHC) (posyandu), number of family members, and family income. This study used an observational design with a case-control approach. The research sample consisted of 202 children under five years old in the work area of Aluh-aluh Community Health Center (CHC) (puskesmas) of Banjar District, selected using probability sampling with simple random sampling. The research location was in the work area of Aluh-aluh CHC of Banjar District. Data analysis was performed using logistic regression tests. There was a relationship between birth weight, exclusive breastfeeding, immunization completeness, and regular visits to integrated health posts with underweight status, with Odds Ratio (OR) values of 18.8, 1.97, 3.33, and 3.05 respectively. There is no relationship between birth length, history of infectious diseases, family income, and number of family members with underweight status. The most influential risk factors for underweight occurrences are birth weight and immunization completeness, with OR values of 20.13 and 2.58 respectively. The probability of underweight due to risk factors can be predicted as follows: 90.1% due to Low Birth Weight (LBW), 82.0% due to incomplete immunization, and 92.9% due to both LBW and incomplete immunization.
