A longitudinal study of growth in Newcastle upon Tyne adolescents.

White Newcastle upon Tyne schoolchildren born in 1962 were examined at approximately half-yearly intervals from 9 to 17 years of age. During the last year of compulsory education losses to follow-up became selective with respect to socio-economic background, and the results reported here are restricted to 564 boys and 669 girls seen regularly between the ages of 10 and 15 years at least. Newcastle adolescents were slightly shorter and lighter than the London children on whom Tanner's British Standards were based.

Weight-for-height in adolescence.

Weight-for-height in adolescence was investigated on the basis of observations on 669 boys and 753 girls. It was found: (a) that given the age, the expected weight of individuals of the same height changes considerably with pubertal status; (b) that the change in weight for a given change in height also depends on pubertal status, and (c) that these relations vary with age so that chronological age should be taken into account when constructing weight-for-height standards. Interpretation of weight-for-height standards is briefly discussed.

Malaria infection of the placenta in The Gambia, West Africa; its incidence and relationship to stillbirth, birthweight and placental weight.

The incidence of placental malaria at parturition and its effects on the conceptus have been investigated in The Gambia, West Africa. Malarious placentae occurred in 1300 (20.2%) of 6427 singleton births, in 32 (18.

A birth-to-maturity longitudinal study of heights and weights in two West African (Gambian) villages, 1951-1975.

Records of heights and weights kept for more than 25 years for two neighbouring Gambian villages have been used to describe the pattern of growth. There was no secular trend in height. Children who died during the investigation were smaller and lighter than the survivors, but the interval between the last available dry-season measurement and death was not associated with the degree of deficit in height and weight.
