A 2-year longitudinal nutritional survey of 405 Northumberland children initially aged 11.5 years

Abstract
Children (405), initially of average age 11.5 yr, recorded all food and drinks consumed for 3 consecutive days (with an interview on the 4th day) on 5 separate occasions over a 2-yr period. Food tables enabled nutrient intakes to be calculated. The data collected were found to be of high reliability. The mean energy intakes showed broad agreement with other recent British dietary surveys but were well below those recorded in a prewar study and the FAO/WHO (1973) recommended levels. They were slightly below the current Department of Health and Social Security (DHSS; 1979) recommended intakes. Over the 2-yr period, the energy intake of the boys increased by 13% compared with an increase of only 7% in the girls. The Fe and vitamin A intakes of all groups of children were low compared with current recommendations (DHSS, 1979). This seems to be a result of falling energy intake. Mean Ca intakes were also only marginally in excess of the recommended intake, and those of most of the girls would fall below the recommendation if the proposal to end the fortification of flour (DHSS, 1981) is implemented.
