Dietary calcium intake in 18-year-old women: comparison with recommended daily intake and dietary energy intake

Abstract

Average dietary calcium intake and energy intake of 113 18-year-old university students in Western Australia was examined. Four-day, weighted diet records, including 1 weekend day, were completed by the subjects. A large proportion of the students (68%) had an average daily calcium consumption below the 800 mg recommended by the National Health and Medical Research Council of Australia. A strong positive association was also found between dietary calcium and dietary energy intakes. Many young women on self-imposed energy reduction diets are at risk of a dietary calcium intake deficit at a time when it should be enhanced. These findings are significant for nursing practice as they indicate the need for further health education concerning the importance of dietary calcium in young women.
