  1. Estimated dietary calcium intake and food sources for adolescent females : 1980-92.

    Article - En anglais

    Purpose 

    To estimate dietary calcium intake of three groups of adolescent females ages 11-12 years, 13-14 years, and 15-18 years during four separate 2-year time periods from the years 1980-92 ; and to identify their food sources of calcium.

    Methods 

    Nutrient intake survey based on 14-day food consumption records collected from four national representative samples of 4,000 United States households.

    Results 

    Dietary calcium consumption declined significantly (p<. 01) over the 10-year period for the 15-18 year olds.

    Calcium intake was significantly lower for 13-14 year olds compared to the youngest age group, and for 15-18 year olds when compared to the two younger age groups for all four study periods (p<. 01).

    Over 90% of all adolescent females consumed<100% of the RDA for calcium during all data collection periods.

    The percentage of adolescent females who consumed less than two-thirds of the RDA increased with age.

    Seventy-seven percent of 15-18 year olds consumed below this level from 1990-92.

    Milk and milk products were the best food sources of calcium contributing over one-half of the calcium to the diet.

    This percentage declined over time and with age to 44% for the 15-18 year old females in 1990.

    This drop can be attributed to a 7-12% decline in fluid milk consumption for the 11-12 year olds and 15-18 year olds, respectively. (...)
