This research focuses on the smoking rates among the Active Duty Air Force (ADAF) personnel and the association of smoking and cost of hospitalization because of diseases related to smoking. Three types of analyses were used in this research. The Contingency Analysis was based on the data taken from the Air Force Web HA questionnaire. The Pivot Table Analysis and the Regression Analysis were based on a second data set associated with the cost of hospitalization. The Contingency Analysis showed that smoking in the U.S. Air Force is more prevalent among the enlisted, males, and the younger age groups. The Pivot Table Analysis demonstrated that ischemic heart disease and cerebrovascular disease present the highest cost. Moreover, enlisted exhibit higher total cost compared to officers, but when referring to the average cost, the situation is reversed. The Regression Analysis exhibited that the variables, related to socio-demographic characteristics, that explain better the cost of hospitalization are the age group of 45-60, the enlisted personnel, and all the pay ranks of the officers, while the diseases that affect more the cost of hospitalization are ischemic heart disease, cerebrovascular disease, malignant neoplasms of the urinary bladder, and other arterial diseases.
