The Swedish Adoption/Twin Study of Aging (SATSA)

Principal investigator: N Pedersen

Location: Sweden.

Study type: longitudinal

Topic: twins separated at an early age and reared apart and a matched sample of twins reared together, twin study on aging

Status: ongoing

Data: information on health status, on how the participants were raised, work environment, alcohol consumption, dietary and smoking habits, social support, life events, personality, and attitudes. In-person testing: blood sampling, a health examination (blood pressure, spirometry, and grip strength), interviews, tests of functional capacity, cognitive abilities, and memory. Blood samples have provided clinical chemistry data, genotyping, methylation data, and telomere lengths.

Objective: to study the origins of individual differences in aging and the environmental and genetic factors that are involved.
