[Depression and seasonal sensitivity among medical students residing in high southern latitudes].

Background: There is no evidence for the association of depressive symptoms with the sense of well-being of undergraduate medical students residing in high southern latitudes (HSL).

Aim: To assess the frequency of depressive symptoms and its relationship with seasonal sensitivity and quality of life in medical students residing in HSL.

Material And Methods: The Beck anxiety and depressive symptoms inventory, the seasonal pattern assessment questionnaire and the quality-of-life questionnaire of the WHO were applied to 102 medical students residing in Magallanes, Chile.

Results: Fifty-two percent of respondents reported some degree of depressive symptoms. These symptoms were significantly associated with the seasonal pattern score (r = 0.432, p < 0.01). They were also inversely associated with parameters of physical health and psychosocial health (r = -0.567, p < 0.01 and r = -0.708, p < 0.01, respectively). There was also a correlation between depressive and anxiety symptoms.

Conclusions: Depressive symptoms are common in medical students residing in HSL and they are associated with seasonal sensitivity and quality of life measures.
