Short- and long-term sunlight radiation and stroke incidence.

ABSTRACT:

Objective

Examine whether long- and short-term sunlight radiation is related to stroke incidence.

Methods

Fifteen-year residential histories merged with satellite, ground monitor, and model reanalysis data were used to determine sunlight radiation (insolation) and temperature exposure for a cohort of 16,606 stroke and coronary artery disease-free black and white participants aged ≥45 years from the 48 contiguous United States. Fifteen-, 10-, 5-, 2-, and 1-year exposures were used to predict stroke incidence during follow-up in Cox proportional hazard models. Potential confounders and mediators were included during model building.

Results

Shorter exposure periods exhibited similar, but slightly stronger relationships than longer exposure periods. After adjustment for o
