Osteoporosis was determined as indicated if one or more of 2 conditions were satisfied: (1) Answer yes to question “Has a doctor ever told you that you had osteoporosis, sometimes called thin or brittle bones?” and (2) Answer yes to question “Has a doctor ever told you that you had broken or fractured your hip?”. ORs for osteoporosis were calculated for each quartile after adjustments for age, gender, kcal, BMI, intakes of calcium, protein, total dairy foods, and vitamin D, and flags to denote supplemental calcium, supplemental vitamin D, supplemental multi vitamin/mineral and prescription medication for osteoporosis and estrogen medication (females only).
^aP trend values indicate statistically significantly different trends in 4 quartiles.
