The purpose of this work was to examine the relationships between geographical coordinates and the prevalence of winter depression (SAD(W)), and to compare the sleep characteristics and chronotype of youths with and without SAD(W). We conducted a cross-sectional study of self-reported sleep characteristics, chronotype and winter depression in northern European Russia. Two questionnaires, the Munich Chronotype Questionnaire (MCTQ) and the Seasonal Pattern Assessment Questionnaire (SPAQ), were administered to a total of 3435 adolescents aged 10-20years (1517 males and 1918 females). The prevalence of SAD(W) in the study population was 8.4% and sub-SAD(W) 11.8%. Four variables predicted the likelihood of SAD(W) in youths: sex [higher in females: odds ratio (OR): 1.87, P
