Secular trends in weight, weight-for-height and triceps skinfold thickness in primary schoolchildren in England and Scotland from 1972 to 1980.

Measurements of height, weight and triceps skinfold thickness were obtained from English and Scottish schoolchildren from 15 birth cohorts over the period 1972-1980. Positive trends in weight were found for boys and girls in both countries, but in England they were less than expected from the increases in height. The increase in weight-for-height in Scotland was paralleled by a greater increase in triceps skinfold in Scottish than in English children. Scottish children remained shorter, lighter and thinner than English children, but similar in weight-for-height. Separate monitoring of trends in obesity for English and Scottish children should continue.
