Psychosocial factors, gender, and sleep.

Low social support may contribute to poor sleep, more so than adverse aspects of demand and control and more so for women than men. This study on 1,179 working individuals, 623 women and 556 men, from the Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) study investigated the association between sleep and psychosocial factors. Chi-square analyses investigated the associations among sleep and demand, control, social networks, and emotional support. A logit log-linear model analyzed interactions. More women reported poorer sleep when perceiving adverse psychosocial factors. Interactive effects were found between adverse scores on demand, control, and emotional support. A multivariate partial least square analysis showed that poorer health, pain, and adverse aspects of emotional support and social networks contributed significantly to the pattern of poor sleep.
