Sodium, potassium, calcium, magnesium, and phosphorus intakes of infants and children: Bogalusa Heart Study.
Electrolyte and mineral intakes assessed by 24-hour dietary recall were examined for race and sex differences in cohorts of infants and school-age children at 6 months and at 1, 2, 3, 4, 10, 13, 15, and 17 years. A fourfold increase in sodium intake occurred from 6 months to 4 years, and potassium intake doubled. Sodium increased from 0.88 gm at 6 months to 3.21 gm at 4 years and 3.67 gm by 17 years; a slight increase for potassium was noted from 4 to 17 years for boys. Calcium intake was relatively constant from 6 months to 17 years. Boys had higher intakes of sodium and sodium per kilogram body weight than did girls. Black children at 2, 3, and 4 years had significantly higher sodium, potassium, calcium, phosphorus, and magnesium expressed as total intake and per kilogram body weight than white children did. At 6 months, 66% of the infants exceeded the National Research Council's recommended range for sodium. At 1 to 10 years, 90% to 100% and at 13 to 17 years, 60% to 65% exceeded the recommended range. In contrast, 58% to 77% of preschool children and only 5% to 20% of school-age children surpassed the recommended potassium range. Fifty percent to 70% of children more than 10 years old achieved the recommended range for potassium. Approximately half of the children 6 months through 4 years of age met the Recommended Dietary Allowance (RDA) for calcium. Sixty percent to 80% of adolescents ingested less than two-thirds the RDA. Girls had lower intakes than did boys.(ABSTRACT TRUNCATED AT 250 WORDS)
