NILS-LSA, "National Institute for Longevity Sciences-Longitudinal Study of Aging" is a long-term longitudinal epidemiological study on aging conducted by the National Center for Geriatrics and Gerontology.

This long-term longitudinal epidemiological study on aging conducts surveys repeatedly in the same cohorts over long period of time, and this research aims to identify the process of aging and the factors leading to the onset of geriatric diseases including dementia, osteoporosis, and senile hearing loss.

In the Section of NILS-LSA, the NILS-LSA data are utilized and the analytical results are widely applied to conduct research in aging and prevention of geriatric diseases.

Longitudinal Study (NILS-LSA)

■National Institute for Longevity Sciences - Longitudinal Study of Aging (NILS-LSA)

The NILS-LSA is a longitudinal study to observe age-related changes among middle-aged and elderly community dwellers. In this project, the normal aging process has been assessed using detailed questionnaires and medical checkups, anthropometrical measurements, physical fitness tests, and nutritional examinations.

The initial survey of NILS-LSA involved 2,267 men and women aged 40 to 79 years, including approximately 300 men and 300 women for each decade of life. Participants included were gender- and decade age-stratified random samples living in Obu-shi and Higashiura-cho, Aichi Prefecture, Japan. They have been followed up every 2 years from the first study-wave (November 1997 - April 2000), second study-wave (April 2000 - May 2002), third study-wave (May 2002 - May 2004), fourth study-wave (June 2004 - July 2006), fifth study-wave (July 2006 - July 2008), sixth study-wave (July 2008 - July 2010), and seventh study-wave (July 2010 - July 2012). Each study-wave was conducted biennially; the total length of the first through seventh waves was 15 years.

When participants could not be followed up (e.g., they moved to another area, dropped out for personal reasons, or died), new age- and sex-matched participants were randomly recruited. All study-waves included nearly 1200 men and 1200 women.
