Evidence suggests that in old age, women are lonelier than men. Gender differences in loneliness are often explained by gender differences in longevity, social status and loss, health, and mobility-well-established predictors that may influence loneliness differently in "younger" (40-59 years) and "older" (60-80 years) groups of men and women in the second part of life. This study explores loneliness in men and women ages 40 to 80 years at baseline over a 15-year period using panel data from three waves of the Norwegian Life Course, Ageing and Generation Study (N = 2,315). Our analyses show that women were more lonely than men also in adjusted analyses. Logistic regression analyses indicated that loss of a partner and poor mental health are prospectively related to loneliness among men and women, whereas other factors like becoming a partner, stable singlehood, and poor physical health were related to loneliness among women but not men.
