Cardiovascular fitness is associated with cognition in young adulthood.

During early adulthood, a phase in which the central nervous system displays considerable plasticity and in which important cognitive traits are shaped, the effects of exercise on cognition remain poorly understood. We performed a cohort study of all Swedish men born in 1950 through 1976 who were enlisted for military service at age 18 (N = 1,221,727). Of these, 268,496 were full-sibling pairs, 3,147 twin pairs, and 1,432 monozygotic twin pairs.

End-of-life in a Swedish population: demographics, social conditions and characteristics of places of death.

The objectives of this study were to identify and describe the demographics and social conditions as well as characteristics of the places of death in a randomly selected sample that died in a county in Sweden during 2001. The present study reports part of the findings from a larger study undertaken during 2003 using a survey design of retrospective reviews of death certificates, medical records, and nursing records. Among several noteworthy findings are: first, an examination of these individuals' living arrangements reveal not only a large and vulnerable group that lives alone at the end-of-life but also a group living separated from their partners near end-of-life; second, individuals differ with respect to residence prior to death, that is private homes versus residential care facilities, imparting highly different contexts of care at the end-of-life; and third, a high prevalence of institutionalized deaths demonstrates that places of death other than hospitals and residential care facilities are uncommon, if not rare.
