Objectives. We analyzed the role of sociodemographic factors,chronic-disease risk factors, and health conditions in explaininggender differences in disability among senior citizens.
Methods. We compared 1348 men and women (mean age = 79 years)on overall disability and compared their specific activitiesof daily living, instrumental activities of daily living (IADL),and mobility limitations. Analysis of covariance adjusted forpossible explanatory factors.
Results. Women were more likely to report limitations, use ofassistance, and a greater degree of disability, particularlyamong IADL categories. However, these gender differences werelargely explained by differences in disability-related healthconditions.
Conclusions. Greater prevalence of nonfatal disabling conditions,including fractures, osteoporosis, back problems, osteoarthritisand depression, contributes substantially to greater disabilityand diminished quality of life among aging women compared withmen.
