  1. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Kelsey M Mangano, MS, RD: University of Connecticut (UConn) Stephen J Walsh, Sc.D.: UConn Karl L Insogna, MD: Yale University Anne M Kenny, MD: UConn Jane E Kerstetter, RD, PhD: UConn JOURNAL OFTHE AMERICAN DIETETICASSOCIATION Mangano K, et al, J Am Diet Assoc. 2011; 111 (May).

  2. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Background • Assessing total calcium intake across the lifespan is important because higher lifetime calcium intake is associated with improved bone mass • Maintaining adequate calcium intake with aging is complicated by the fact that energy intake declines with age Nieves et al, 2008 Morely et al, 2001 JOURNAL OFTHE AMERICAN DIETETICASSOCIATION Mangano K, et al.J Am Diet Assoc. 2011; 111 (May).

  3. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Methods • The National Center for Health Statistics presently conducts NHANES in biennial waves • Designed to assess the health and nutritional status of adults and children in the US via an in person interview and medical examination • Participants • Assessed from the years 2003-06 • Aged 19 y or older • n = 9,475 • Calcium intake assessment • Includes both dietary and supplemental intake • Evaluates patterns of intake across age groups JOURNAL OFTHE AMERICAN DIETETICASSOCIATION Mangano K, et al. J Am Diet Assoc. 2011; 111 (May).

  4. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Serum Vitamin C (mg/dl) by Salad Intake Results JOURNAL OFTHE AMERICAN DIETETICASSOCIATION Mangano K, et al.J Am Diet Assoc. 2011; 111 (May).

  5. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Serum Vitamin C (mg/dl) by Salad Intake Results Median daily calcium intake from dietary sources, energy intake, calcium: energy ratios among US adults by gender and age group MEN WOMEN JOURNAL OFTHE AMERICAN DIETETICASSOCIATION Mangano K, et al.J Am Diet Assoc. 2011; 111 (May).

  6. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Serum Vitamin C (mg/dl) by Salad Intake Results • Non-supplement users had a lower median intake of dietary calcium from food sources than supplement users in corresponding age groups (p=0.005 in men, p<0.001 in women) • In women, those who used supplements had a greater decline in dietary calcium intake with age (28%, p<0.001) compared to non-supplement users (5% decline, p=0.33) • Supplemental calcium intake among supplement users increased with age in both men and women (p<0.001) Mangano K, et al.J Am Diet Assoc. 2011; 111 (May).

  9. Calcium Intake in the United States from Dietary and Supplemental Sources across Adult Age Groups: New Estimates from NHANES 2003-2006 Conclusions • American adults may experience an age-related decline in calcium intake explained, in part, by a concurrent decline in energy intake • The age-related increase in the frequency and levels of supplemental intake counteracts, in part, the decline in dietary calcium and energy intake, but does not appear to produce sufficient calcium density to achieve recommended levels of calcium JOURNAL OFTHE AMERICAN DIETETICASSOCIATION Mangano K, et al. J Am Diet Assoc. 2011; 111 (May).
