Predictors and persistence of foot problems in women aged 70 years and over: A prospective study

ObjectiveTo examine the prevalence and correlates of foot problems in older women over a 6-year period.Study designWomen aged 70–75 years who participated in the Australian Longitudinal Study on Women's Health completed a postal questionnaire incorporating questions relating to demographics, major medical conditions and health status in 1999 (n = 8059) and 2005 (n = 4745).Main outcome measuresSelf-reported foot problems at baseline and at 6 years follow-up, major medical conditions, body mass index (BMI).ResultsAt baseline, 26% of the sample reported foot problems. At follow-up, 37% remained free of foot problems, 36% had developed a new foot problem, 13% experienced resolution of their foot problems and 14% experienced persistent foot problems. Increase in BMI was significantly associated with the development of new foot problems and the persistence of existing foot problems.ConclusionsFoot problems are common in older women and are associated with increased BMI. Maintaining a healthy bodyweight may therefore play a role in the prevention of foot disorders in older women.
