A two-year longitudinal study of dietary intake in relation to the growth of 405 English children initially aged 11-12 years.
This report is of a two-year longitudinal study of dietary intake and growth in height and weight of 405 children, initially aged 11-12 years. Between 1979 and 1981 they each recorded their food intake on five occasions for three consecutive days using a diet diary with a 20 min private interview on the fourth day. Computerized food tables were used. Social class was recorded. The usual differences in height, weight and growth increments between the social classes were found. There were no significant differences in nutrient intake between social classes. Within a social class there were few statistically significant correlations between energy or protein intake and height or weight increments. It was concluded that a very high reliability of food intake measurements would be required in order to relate diet to growth and many other factors (e.g. energy expenditure, body composition and puberty) may also mask any such relationship. Social class alone would seem an inadequate means of allowing for such factors.
