Dairy product consumption has been on the decline for decades in the US and worldwide, and the increase in plant-based substitutes has grown substantially. Osteoporosis and the risk of bone fractures are serious public health issues. To date, little scientific-based studies have compared the relationship between calcium intake from dairy sources vs non-dairy sources and bone mineral density. The purpose of this study is to compare the relationships between calcium consumption from dairy vs. non-dairy sources and bone mineral density among college students. There was a total of 66 participants in the study including 15 (23%) males and 51 (77%) females. The participants’ ages ranged from 17 to 43 years with 48 (74%) being white, 16 (25%) African American, and 1 (1%) Hispanic. There was a significant difference found between males (M =.00, SD = .00) and females (M =.62, SD = 1.21) for z-scores, t(37), p <.01. There was a significant difference found between males (M = 126.27, SD = 22.44) and females (M = 110.21, SD = 21.55) for stiffness index scores, t(60), p < 02. There was a significant difference found between whites (M = 109.60, SD = 20.67) and non-whites (M = 129.27, SD = 22.86) in stiffness index scores t(58), p < .01. There was a significant difference in dairy calcium intake between participants who did not meet the RDA (M = 293.43, SD = 249.36) and participants who did meet the RDA (M = 940.98, SD = 618.89) t(15.54), p < .01. This study confirmed that not only were participants who didn’t consume dairy calcium not meeting the RDA, but they weren’t making up for the difference in non-dairy sources.
