Relative Risk (RR) of Total Incident Cancer and of Site-Specific Cancer by Educational Attainment in Women.

Abbreviations: RR, relative risk; CI, confidence interval; BMI, body mass index (calculated as weight kilograms divided by height in meters squared); MHT, menopausal hormone therapy.
ap for trend across education groups.
bAge-adjusted Incidence rates are per 100,000 person-years by 5 year age intervals.
cMultivariate models included the following covariates: age (yrs); race (White, Black, Hispanic and Asian, Pacific Islanders and Native Americans, combined); smoking (Never, Quit < = 1 pack per day, Quit>1 pack per day, Currently smoking < = 1 pack per day, Currently Smoking>1 pack per day); alcohol consumptions g/day (0; 0.1−<5, 5 −<15, 15<30, 30+); energy (Kcal/day);BMI (<25, 25−<30, 30−<35, 35+); Physical activity (Frequency of at least 20 minutes that caused increases in breathing or heart rate, or worked up a sweat: Never/Rarely, 1–3 time per month, 1–2 times per week, 3–4 times per week, 5+ times per week, Unknown), married (yes/no); family history of cancer (yes/no); MHT use (Current, Former, Never). In female specific anatomical sites, a combined variable of age at first birth and number of children was included.
dSmoking related cancers include sites: head neck, esophageal, lung, pancreas, bladder.
eFor the sites of colon, breast and ovarian models were adjusted for screening behavior.
fWomen who reported a hysterectomy were excluded from the statistical models for endometrial cancer.
gWomen with both ovaries removed were excluded from the statistical models for ovarian cancer.
