Seasonal variation in mental depression and its correlation with occupation

  • Simo Näyhä
Studies of Depression and Suicide


The seasonal variation in non-psychotic depressive morbidity was examined in 806 males aged 50 years and over using a 12-item questionnaire. A significant seasonal pattern in depressivity was revealed, with its peak in early summer. There was also a significant difference in the pattern depending on occupation, the summer peak for depression being typical of the middle social classes and agricultural occupations, while the peak tended to be focused later in the year at both ends of the social scale and in occupations outside agriculture. The monthly variation in depression showed some association with length of day but not with air temperature.
