Abstract

Although it is known that women have a higher prevalence of asthma than men, it is not known whether and/or how gender differences in asthma severity are affected by age. Asthma hospitalization rates were compared for men and women in New York State from 1990 through 2006 between the ages of 20 and 84. Female and male hospitalization rates were calculated and characterized for the different age intervals. The ratio between female to male hospitalization rates were compared for different age groups. While males showed an overall linear increase in hospitalization rates with increasing age, women had a steeper increase in hospitalization rates followed by a slowing beginning at the ages between 40–54. The ratio of the female to male hospitalization rates was maximal in this age interval, with a mean ratio of 2.41 compared to 1.97 in other ages. For each year, this female to male ratio was consistently higher for the age range between 40 to 54 than for other ages, and this difference remained when admissions associated obesity, tobacco dependence, and chronic non-asthmatic pulmonary disease were excluded. Differences between the hospitalization rates for men and women vary by age. The gender gap in hospitalization rates appears to be maximal between the ages of 40 and 54. This may reflect age related asthma prevalence and/or severity differences between men and women.
