Younger and older patients with severe chronic obstructive pulmonary disease have similar pulmonary and physical health limitations, based on data from 1,058 adults.
Although chronic obstructive pulmonary disease (COPD) generally appears in older patients, the prevalence among adults aged 45-55 years was 6.5% in 2014-2015, wrote Rosanne J.H.C.G. Beijers, PhD, of Maastricht (the Netherlands) University Medical Center, and colleagues. However, data on the early-onset COPD phenotype are limited. In particular, the extent to which younger patients with early-onset severe COPD experienced the same physical and mental health problems as older patients with similar degree of airflow limitation has not been examined, they said.
In a study published in Clinical Nutrition, the researchers analyzed data from adults with COPD who were referred for pulmonary rehabilitation at a single center between July 2013 and August 2018. Severe disease was defined as FEV1< 50%, and early onset was defined as younger than 55 years. The mean age difference between older and younger patient groups was 15.8 years.
The study population included 79 individuals with early-onset severe disease, 54 with early-onset mild to moderate disease, 158 older adults with severe disease, and 103 older adults with mild to moderate disease. The researchers compared disease markers including body composition, physical performance, and mental health between the groups. A significantly greater proportion of the early-onset group were women, compared to the older group (64% vs. 44%).
In comparing early-onset and older patients with severe COPD, the researchers found that clinical characteristics were similar for body composition, skeletal muscle index, fat percentage, and bone mineral content, and for physical performance factors including the percent predicted maximal work capacity (Wmax), 6-minute walk test, and isokinetic strength. However, a higher prevalence of depression appeared in the early-onset severe-disease patients, compared with the older severe-disease patients (51.9% vs. 32.7%; P = .029).
Although the prevalence of depression was not based on a clinical diagnosis, this finding should prompt health care professionals to pay more attention to psychosocial and emotional well-being in early-onset severe COPD patients, the researchers noted.
In comparing early-onset severe-disease patients and early-onset patients with mild to moderate disease, patients with early-onset severe COPD had significantly lower exercise performance, based on a 6-minute walk test and percent predicted Wmax. However, body composition and isokinetic muscle strength were not significantly different between both early-onset groups.
The findings were limited by several factors including the relatively small number of early-onset patients and the lack of data on whether older patients were diagnosed with severe COPD at a younger age, and more research using age and lung function at the time of diagnosis is needed, the researchers noted. However, the results highlight the importance of early identification of patients at risk for early-onset severe COPD, they said. “Within these individuals at risk, special attention should also be paid to the development of extrapulmonary disease manifestations such as exercise limitations, impaired body composition, and psychological and emotional problems,” the researchers said. “Subsequently, intervention strategies need to be applied that not only focus on the regular advice of quitting smoking but also include decreasing the exposure to air pollutants and promoting a healthy lifestyle including physical activity and a healthy diet,” they added.
The study received no outside funding. Lead author Dr. Beijers had no financial conflicts to disclose.
