<![CDATA[ISPA can be caused by three factors, namely the individual's childhood factors, behavioral factors, and environmental factors. Individual childhood factors include: child's age, birth weight, nutritional status, vitamin A, and immunization status. Behavioral factors include behavior to prevent and control CI in infants, or the active role of the family/community in fighting CI. Environmental factors include: indoor air pollution (cigarette smoke and high concentrations of cooking fuel smoke), house ventilation and residential density (Prabu, 2009). The habit of parents smoking inside the house makes babies become passive smokers who are constantly exposed to cigarette smoke. Homes with parents who have smoking habits have the opportunity to increase the incidence of ARI by 7.83 times compared to homes where parents do not smoke in the house. Meanwhile, the number of smokers in the family is quite large (Rahmayatul, 2013). Onan Hasang Medical Center that ISPA is a disease that ranks in the top 10 every year, based on this, researchers are interested in conducting research.
