We estimated the intake of nutrients known to impact bone health in young (Y; n=27; ages 21–25, mean 22.7) and older (O; n=29; ages 37–63, mean 49.2) adult Caucasian women in rural Kentucky. The Y women were college students; the O women were college employees. Three‐day detailed food diaries were completed by each subject and analyzed for intakes of vitamin D, calcium, phosphorus and magnesium. Results showed that although the Y group was more likely to take a multivitamin, and the O group more likely to take supplemental Ca, no statistical differences in nutrient intakes between the two age groups could be demonstrated. However, the intakes for vitamin D, Ca, and Mg in both groups were statistically below the age‐specific dietary reference intakes (DRIs) for these nutrients. The pooled mean daily intake for vitamin D averaged 64% of the DRI (P<0.05). For Ca, this was 78% (P<0.05). For phosphorus, pooled intakes averaged 113% of the DRI. For Mg, this was 57% (P<0.05). 47% of the Y group took a daily multivitamin, but only 12% of the O group. Only 7% of the Y group took supplemental Ca, but this was 36% in the O group. 36% (Y) to 40% (O) reported getting regular weight‐bearing exercise, and 33% (Y) to 42% (O) reported that they regularly use a tanning bed. Conclusions: although we could demonstrate no differences in nutrient intakes between the two age groups, the mean intakes of vitamin D, Ca and Mg for both groups of women were significantly below recommended levels.
