Seasonal Variation Of Suicide Rates Within Alaska: Associations Of Age And Sex, Jonviea Chamberlain

Masters Theses 1911 - February 2014

Background: Suicide rates among Alaska Natives in rural Alaska are almost 16 times higher than the national average. Some studies in northern latitudes have shown seasonal variation among suicide rates, with differences in patterns by age and sex, reasons for this variation and contributing factors are unclear. We modeled our hypotheses based on the assumption that vitamin D deficiency influences seasonal variation of suicide. We assessed the relationship between age, sex and seasonal variation of suicidal behavior in a rural region of Alaska. Methods: We utilized data from 804 individuals who exhibited lethal and nonlethal suicidal behavior (1990-2009). Information on …

Objective: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been implicated as protective against suicide. However, it is uncertain whether a higher intake of EPA and DHAor of fish, a major source of these nutrients, lowers suicidal risk among Japanese, whose fish consumption and suicide rate are both high. This study prospectively examined the relation between fish, EPA, or DHA intake and suicide among Japanese men and women.Method: Subjects were 47,351 men and 54,156 women aged 40–69 years who participated in the JPHC Study, completed a food frequency questionnaire in 1995–1999, and were followedfor death through December 2005. We used …
