Seasonal affective disorder and latitude of living
SUMMARY Aim – Since the importance of latitude of living for the prevalence of Seasonal Affective Disorder (SAD) is unclear, the study aims to test the latitude hypothesis by comparing SAD in two rather similar groups of students living at latitudes far apart. Methods – Two groups of students, 199 i...
