I Indonesia has a lower breastfeeding rate compared to other countries in South East Asia. Breast milk helps babies develop an immune system, protecting them from various infections. Acute respiratory infections are commonly found among children. For that reason this research is conducted to determine the connection between exclusive breastfeeding and acute respiratory infection among children aged 6 to 24 months. This research uses cross sectional design that involves 182 correspondents whom are mothers and patients of RS X, Jawa Barat. Data are compiled by interviewing the aforementioned patients using a questionnaire that asks age, weight, birth weight, history of breastfeeding, immunization history, mothers education background and exposure to cigarette smoke. Significance level used is 0,05. The Chi Square data analysis shows that there is a connection between the history of breastfeeding (p=0,000), exposure toward cigarette (p=0,001) with risk rate of respiratory infections. There are no connections found between nutrition status (p=0,259), birth weight (p=0,715), immunization history (p=0,065), the mothers’ patients education background (p=1,000) with risk rate of respiratory infections. Based on the result of the data analyzed, the researcher concludes that there is a connection between the history of breastfeeding and the exposure of cigarette toward the risk rate of respiratory infections. And there are no connections found between nutrition status, birth weight, immunization history and education background toward the risk rate of respiratory infections. It can therefore be proven that breastfeeding has an effect toward the risk rate of respiratory infections in children.
