Incidence and associated factors for single and recurrent falls among the elderly in an urban community of Beijing.

Objective: To investigate the incidence of falls and recurrent falls, and explore associated factors for single and recurrent falls among urban community-dwelling elderly in Beijing.

Methods: A cross-sectional study was conducted in 472 elderly in the Longtan community of Dongcheng district, Beijing in 2009. Data regarding the incidence of fall and recurrent falls in the previous year, as well as associated factors were collected from the elderly through face-to-face interviews.

[A prospective study on recurrent falls and related factors in elderly from the urban communities in Beijing].

Objective: To investigate the incidence and risk factors for recurrent falls in community-dwelling elderly in Beijing.

Methods: A cross-sectional study was conducted in 472 elderly in the Longtan community of Dongcheng district,Beijing in 2009. Data on recurrent falls within the past 12 months were collected through face-to-face interview, with both single factor analysis and logistic regression analysis used to explore the related factors on recurrent falls in the elderly.

[Association between genetic factor and physical performance].

Correlation study between physical performance and gene has become a hot topic. Evidences have indicated that human capacity is partially influenced by genetic factors. Since 2000, the genetic studies of locomotion have progressed rapidly.

[Human genetics of physical performance].

Development of human molecular genetics gradually revealed that certain people seem to have congenital capacity in physical performance, and this capacity may correlate with genes. Recently, more and more evidences have shown that genes control some physical characters, such as extreme motion, muscle strength, endurance, ductility, fatigue recovery, and VO2max, ect. The development of spaceflight in China and nation defence urgently require appearance of this study, and its application will help to find physically potential individuals in advance and save large amount of money in the later systematic training.
