INTERNAL AND EXTERNAL FACTORS OF PNEUMONIA IN CHILDREN UNDER TWO YEARS OF AGE IN INDONESIA

Pneumonia is an infectious disease that can cause death in children. The prevalence of this disease has increased and is mostly found in the 12-23 month age group. This paper aims to examine the internal and external factors associated with the incidence of pneumonia in children under two years of age in Indonesia. The data analyzed comes from secondary data from Riskesdas 2018. The Riskesdas design was cross-sectional. The research sample was all children under two years of age who were collected at the Riskesdas 2018 as many as 36,248 children. Bivariate data analysis using schi-square test and multivariate data analysis using logistic regression test. The results of the analysis showed that the risk factors for pneumonia in children under two years were the child's weight at birth (OR: 1,393; CI 95%: 1,009-1,923), the habit of opening a kitchen window (OR: 1,434; CI 95%: 1,097-1,874) and the smoking habit of other household members in the house (OR: 1,311; CI 95%: 1,088-1,580). These factors together can influence the incidence of pneumonia at under two years of age in Indonesia. Therefore, it is necessary to make efforts to change people's behavior to pay more attention to the health of LBW children, change smoking habits and get used to opening the kitchen window. These efforts can be carried out through outreach activities using various media, both formal and informal, and increasing community participation through the movement.
