Association between anemia and frailty in 13,175 community-dwelling adults aged 50 years and older in China.

Background: Anemia and frailty contribute to poor health outcomes in older adults; however, most current research in lower income countries has concentrated on anemia or frailty alone rather than in combination. The aim of the present study was to investigate the association between anemia and frailty in community-dwelling adults aged 50 years and older in China.

Methods: The study population was sourced from the 2007/10 SAGE China Wave 1.

Long-term exposure to ambient PM associated with fall-related injury in six low- and middle-income countries.

Exposure to ambient air pollution has been linked with adverse health outcomes of the circulatory and nervous systems. Given that falls are closely related to circulatory and nervous health, we hypothesize that air pollution may adversely affect fall-related injury. We employed Wave 1 data from 36,662 participants aged ≥50 years in WHO's Study on Global AGEing and Adult Health in six low- and middle-income countries.
