Determinants of Plasma 25-Hydroxyvitamin D Concentrations among Breast Cancer Survivors in Korea.

摘要: We identified demographic, lifestyle, and clinical factors associated with vitamin D status among breast cancer survivors. The prediction model may be a useful surrogate of circulating 25-hydroxvitamin (25(OH)D) concentrations when this measure was not available. included total 216 Korean survivors aged 21–79 years who had been diagnosed stage I to III primary surgery at least 6 months before enrolment. used linear logistic regressions identify determinants for the plasma 25(OH)D insufficiency (plasma concentration < 50 nmol/L). observed that 48.85% less than nmol/L. following concentrations: time since diagnosis (β = −0.005 1 month increment), supplementary intake 0.06 10 μg/day season blood draw 0.35 summer; β 0.32 fall; 0.26 winter vs. spring), smoking 0.28 former never), use any supplement −0.35 non-use use), parity number −0.30 three or more one) were concentrations. In addition aforementioned variables, body mass index (BMI) prevalence insufficiency. Future studies are needed investigate role in progression
