Background: The ability of walking a quarter mile is predictive of subsequent disability, mortality, and health care costs. Individuals with mobility disability are at increased risk of chronic conditions and unmet care needs. Thus they may misuse prescription medications to self-medicate.
Objectives: We aimed to explore the difference of misuse of four types of prescription medications (sedatives, tranquilizers, painkillers, depression medications) and overall misuse by mobility status and identify the correlates of overall misuse.
Methods: A national probability sample from the survey Midlife in the United States (MIDUS) was used to assess the difference in misuse by mobility status during 2011-2014. To assess the correlates of misuse, mobility status, usual source of care, unmet care needs, insurance coverage, sociodemographic variables, and clinical conditions were added to a survey weighted logistic regression model with backward selection.
Results: Compared to those without mobility disability, individuals with mobility disability had higher risk of misuse in most types of medications and in overall misuse. Mobility disability, lower education, unmarried status, the emergency room or public health clinic as the most often used care, pain, and depressed affect were identified as correlates of overall misuse of studied medications.
Conclusions: Individuals with mobility disability are a vulnerable group susceptible to medication misuse, which warrants the urgent need for interventions to ameliorate misuse and reduce risks in this population.
