Eczema in adulthood is directly associated with an increase in incidence of injuries that cause physical limitations, particularly fracture, bone, and joint injuries, according to the results of a prospective study published online in JAMA Dermatology.
“The risk of bone fracture and other injury causing limitation in adults with eczema has been largely unexplored,” noted Dr. Nitin Garg and Dr. Jonathan I. Silverberg of Northwestern University in Chicago.
“Patients with eczema may be at risk of fracture given their use of systemic corticosteroids, which may decrease bone mineral density [and] therefore, studies describing the prevalence of fracture among adults with eczema are needed,” they added (JAMA Dermatol. 2015;151:33-41 [doi:10.1001/jamadermatol.2014.2098]).

Dr. Garg and Dr. Silverberg used data from the 2012 National Health Interview Survey, which was conducted by the National Center for Health Statistics, to create their prospective, questionnaire-based study. The final analysis included 34,500 adults aged 18-85 years. They controlled for factors such as age, sex, race, Hispanic origin, household income, highest level of household education, family structure, and whether or not the subject was born in the United States.
The prevalence of self-reported eczema or skin allergy was 7.2%, the prevalence of any limitation-causing injury was 2.0%, and any limitation-causing injury in the past 12 months among adults was 7.2%. A fracture and bone or joint injury (FBJI) causing limitation was reported by 1.5% of the study population and other types of injury causing limitation were reported by 0.6%. The prevalence of FBJI causing limitation increased gradually with age, to peak in subjects aged 50-69 years, decreasing thereafter.
In a logistic regression analysis, adults with eczema had a 44% increased risk of any injury causing limitation (adjusted odds ratio, 1.44), and a 67% increased risk of FBJI (aOR, 1.67).
Adults with eczema who also reported experiencing fatigue (aOR, 1.59; 95% CI, 1.16-2.19), daytime sleepiness (aOR, 1.81), or insomnia (aOR, 1.74) had higher rates of FBJI than individuals with sleep symptoms but no eczema. Adults with both eczema and psychiatric or behavioral disorders also were more likely to experience FBJI than individuals suffering from eczema alone, or individuals suffering from psychiatric and behavioral disorders, but not eczema.
“Taken together, these data suggest that adult eczema is a previously unrecognized risk factor for fracture and other injury, emphasizing the importance of developing safer and more effective clinical interventions for itch and sleep problems in eczema, as well as preventive measures for injury risk reduction in eczema,” wrote Dr. Garg and Dr. Silverberg.
