ASSESSING CALCIUM INTAKE IN CHILDREN IN THE LOWER MISSISSIPPI DELTA (LMD) USING 24-HOUR DIETARY RECALL. DIETARY ASSESSMENT METHODS INTERNATIONAL CONFERENCE PROCEEDINGS. Chiang Rai, Thailand. 2003. Abstract No. A2.2. Interpretive Summary:
Technical Abstract: The LMD is a rural agricultural region with high rates of poverty, unemployment, and chronic disease. A telephone-administered 24-hour recall was used to assess dietary intake in households in 36 counties in the LMD of Arkansas, Louisiana, and Mississippi. A two-stage stratified cluster sample representing the population in the 36 LMD counties, and random digit dialing methodology, were used to identify the sample households. This report focuses on the 24-hour calcium intake of 9 to 17 year-old girls since this group is typically the most at risk for under consumption of calcium. These analyses compare the intake of calcium of this group of LMD girls to the Adequate Intake (AI) of 1300 mg recommended by the Food and Nutrition Board of the Institute of Medicine, and how their intake compares to national data. There were no significant differences in mean calcium intake within the LMD between African Americans and Caucasians. Independent sample normal-tests were used to compare LMD data to the Continuing Survey of Food Intakes by Individuals (CSFII) 1994-1996, 1998, which is representative of the U.S. African American LMD girls consumed an average of 842 mg calcium (64.8% of AI) vs. national average of 714 mg (p=0.035). Caucasian LMD girls consumed 701 mg (53.9% of AI) vs. U.S. average of 854 mg (p=0.046). Only 13.5% of African American LMD girls vs. 5.32%(p=0.077) in the U.S. and 5.9% of Caucasian LMD girls vs. 16.69% (p=0.003) in the U.S. consumed the recommended AI for calcium. LMD African American girls consume significantly more calcium and LMD Caucasian girls consume significantly less calcium than their counterparts nationally. Regional studies are vital to identify high-risk sub-groups in the U.S. to design appropriate and targeted interventions. Supported by USDA, ARS Project #6251-5300-003-00D.
