[Trends geriatric disease research evaluated by long-term longitudinal study].

Area of Science:

• Gerontology
• Epidemiology
• Genetics

Context:

• The global population is aging rapidly, leading to an increased prevalence of chronic geriatric diseases.
• Elderly care demands significant resources, highlighting the need for effective prevention and treatment strategies.
• The National Institute for Longevity Sciences (NILS) initiated a longitudinal study in 1997 to address these challenges.

Purpose:

• To conduct a comprehensive, longitudinal study on aging and geriatric diseases.
• To examine a large cohort for age-related health changes and disease progression.
• To identify geriatric disease-related genotypes and risk factors for mild cognitive impairment (MCI).

Summary:

• The NILS Longitudinal Study of Aging (NILS-LSA) involves 2,267 participants from a community population, examined and followed up biennially.
• The study system and examination protocols are detailed.
• Recent findings include analyses of geriatric disease genotypes and MCI risk factors.

Impact:

• Provides crucial data for understanding and managing the health challenges of an aging population.
• Informs public health strategies for geriatric disease prevention and elderly care.
• Contributes to the identification of genetic predispositions and environmental factors influencing cognitive decline in aging individuals.
