Seasonal Variation Of Suicide Rates Within Alaska: Associations Of Age And Sex, Jonviea Chamberlain
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 …
Perceived Recurrence Risk And Health Behavior Change Among Breast Cancer Survivors, E Konieczny
Perceived Recurrence Risk And Health Behavior Change Among Breast Cancer Survivors, E Konieczny
Masters Theses 1911 - February 2014
Over one third of breast cancer survivors report “fear of recurrence” as the primary concern after diagnosis and treatment. Behavior changes such as exercise and weight loss post cancer may reduce recurrence risk. How perceived recurrence risk affects behavior change is unknown. We evaluated this association in the Breast Cancer Survivorship Study, a cross-sectional study of 301 breast cancer survivors. Data on perceived recurrence risk (local and distant) and health behavior change (alcohol, exercise, nutrition, smoking, sun exposure, supplement use, weight) were assessed by mailed questionnaire. Multivariable logistic regressions were used to evaluate associations between perceived recurrence risk and health …
Coffee And Tea Intake And Risk Of Cutaneous Melanoma, Haotian Wu
Coffee And Tea Intake And Risk Of Cutaneous Melanoma, Haotian Wu
Masters Theses 1911 - February 2014
Cutaneous melanoma accounts for less than 5% of all skin cancers but over 75% of skin cancer related deaths. Prior biologic research suggests caffeine may arrest cancer cell formation and metastasis in vivo. Additionally, certain tea components exhibit anti-inflammatory, anti-oxidant, and other anti-carcinogenic effects. Prior epidemiologic studies show possible protective effect of both coffee and tea on risk of melanoma, but results remain inconsistent. We examined the association between coffee and tea intake and risk of cutaneous melanoma using the Women’s Health Initiative Observational Study. Coffee and tea intake were measured through self-administered questionnaires. Melanomas were self-reported and physician adjudicated. …
