To identify risk factors for experiencing nightmares among the Finnish general adult population. The study aimed to both test whether previously reported correlates of frequent nightmares could be reproduced in a large population sample and to explore previously unreported associations.
Two independent cross-sectional population surveys of the National FINRISK Study.
Age- and sex-stratified random samples of the Finnish population in 2007 and 2012.
A total of 13,922 participants (6,515 men and 7,407 women) aged 25-74 y.
N/A.

In multinomial logistic regression analysis, a depression-related negative attitude toward the self (odds ratio [OR] 1.32 per 1-point increase), insomnia (OR 6.90), and exhaustion and fatigue (OR 6.86) were the strongest risk factors for experiencing frequent nightmares (P
