4.2.1 Sex and ageThe prevalence of affective disorders was higher in females (7.1% compared to 5.3% in males). This difference between the sexes was also true for depressive episode and dysthymia, which were around one and a half times higher in females. However, males and females experienced similar rates of bipolar affective disorder (1.8% and 1.7% respectively).
The prevalence of affective disorders was not strongly associated with age and the pattern varied between males and females (Figure 4-1). For females, the prevalence started high and declined in the older age groups. While for males the prevalence started lower, peaked for 35-44 year olds and then declined with increasing age.
