PURPOSE: To assess whether changes in serum level of surfactant protein D, correlate with the rate of decline in lung function among elderly population in China.
METHODS: From 2008 to 2011, a prospective cohort study was conducted on 1278 elderly people (aged 40-75y) in an urban community in Beijing. All the participant were free of severe chronic disease, and underwent standard lung function assessment and blood samples collection every 2 years. At last, 96 participants were enrolled into one of three groups: nonsmoking controls, current or ex-smoking controls, and COPD patients. The serum level of surfactant protein D (SP-D) were measured.
