Objectives: The objectives of this study were to determine dietary intake o
f calcium, intake of food components known to inhibit calcium bioavailabili
ty, demographic factors related to calcium intake, and the knowledge needs
and barriers related to calcium consumption among low-income African-Americ
an women in Baton Rouge, Louisiana.
Methods: Ninety subjects were interviewed at local grocery stores. Calcium
intake was determined using a 24-h recall. In addition, a survey was admini
stered to the subjects to determine knowledge needs and barriers towards ca
lcium consumption.
Results: Subjects' mean dietary calcium intake was below the recommended di
etary allowance (RDA), with 80% of the subjects having a calcium intake bel
ow 75% of the RDA. In addition, intakes of protein and sodium were above th
e recommended amounts. The general knowledge of the subjects concerning the
role of calcium in osteoporosis was high, but this did not have an effect
on the consumption of products containing calcium. The most important barri
ers to dairy product intake were perceived negative taste, perceived associ
ation with digestion problems and the perception that they already had adeq
uate intake.
Conclusion: Inadequate calcium intake in African-American women is affected
by many factors including their lack of awareness of actual consumption. N
utrition education programmes need to address these factors.
