“…No estimate is presented for FH4 since few boys reached this stage. Boys with fathers in unskilled occupations developed facial hair later on average; this result is consistent with those for PHV, AH and V. Hogben (1948) estimated 50~o to be still infantile at 15.5 years, "hair of upper lip" probably corresponding to our FH2. estimated age at FH2 as 14.7 years and FH3 as 16.2 years, approximately.…”

“…Comparisons are difficult because of the uncertain nature of the criteria, particularly since the early stages of voice change are difficult to assess. Hogben et al (1948) reported 50~o with adult voice at 14.5 years and 50~o infantile at 13-6 years. Chang et al (1966) found a mean age of 13.7 years for what seems equivalent to our definition of V2.…”

“…Boys with fathers in unskilled manual occupations reached both stages about five months later on average than did boys in the rest of the sample. These figures may be compared with 16 years for stage AH3 in London boys nearly 40 years ago (Hogben, Waterhouse and Hogben 1948) and 14.6 for stage AH2 in Chinese boys (Chang, Ng, Lee and Chan 1966) and 13.6 for Turkish boys . Neyzi et al also noted social class differences.…”

“…Thus the change of voice appears to occur later in our sample. However, the abovementioned studies were cross-sectional; Chang et al (1966) relied on the information given by the boys themselves strengthened "by the examiner's experience", while the criteria used to decide on the placing of any individual boy are not described by Hogben et al (1948). According to Tanner (1962), the voice begins to deepen at about the time of spurt in sitting height, which is some 0-3 years later than PHV; this agrees well with our estimates of the timing of PHV and of V2.…”

“…Hogben et al (1948) found 50~o adult at 14-2 yearsand 50~o infantile at 13.2 years, while Nicholson and Hanley (1953) found AH2 at 11.6 years; the ages at menarche in the two studies were 13.6 years and 12-8 years respectively. found AH2 at 11"3 years for Turkish girls having menarche at 12.8 years.…”

669 boys and 753 girls born in 1962 and living at home were observed at approximately half-yearly intervals from 9 to 17 years of age. Mean ages of reaching various developmental stages were calculated for voice change and facial hair in boys, menarche and breast development in girls, and for axillary hair in both sexes. Peak height velocity and age at which it occurred were also calculated for both sexes. Means were generally in good agreement with those found about 15 years previously in the Harpenden Growth Study. Most pubertal changes in the present study showed gradients by social class; in boys, development was later in those with fathers in unskilled manual occupations, whereas in girls the greatest differences, where found, were between those with fathers in non-manual occupations and the remainder.

The present study represents one part of a joint investigation of a stratified sample of Edinburgh schoolchildren carried out in collaboration with J. N. Mansbridge (who was investigating dentition and dental caries in the same sample) and with the statistical help of Dr. L. Stein and staff of the Department of Social Medicine, University of Edinburgh. The purpose of the anthropometric study was to provide, in the first instance, crosssectional data which could be used for comparison with similar measurements on other groups of Edinburgh children (e.g., premature babies, mental defectives and others), for comparing children in this city with other geographical populations and for subsequent use in studies of secular changes in the growth of schoolchildren over a period of years. The lack of recent Scottish data for any measurements other than those of height and weight, and the incompleteness even of such data over the whole age-range 5 to 18 years, was an additional reason for undertaking the survey. Clinical assessment of maturity was included in the investigation in order to provide data on age-onset of puberty in both sexes, for which no recent Scottish figures are available. The methods of sampling, techniques of measurement and statistical treatment are outlined, and the basis of classification of the children into maturity groups is indicated. All maturity-grading and measurements, except where otherwise stated, were carried out by one of us (H.S.P.). The basic data which are now presented will be discussed more fully, together with the frequency distributions of length and weight in a subsequent paper (Part H). MlethodsSample. It was desired to obtain as good a sample as possible of the day pupils in the city between the ages of 5 and 18 years: the planning and stratification of the sample was undertaken by the statistical section of the Department of Social Medicine. Ages were reckoned from the date of birth to the date of examination. Since socio-economic factors often influence growth, the children were divided into two groups: those attending local authority schools (non-fee-paying) and those attending private schools (fee-paying). The children were placed in age groups and the proportions of nonfee-paying and fee-paying were dictated by the proportion of schoolchildren in the appropriate group being educated in those types of school in Edinburgh during 1951. The percentages of boys from fee-paying schools in the investigation in each year-age group were approximately 13 from 5 to 11 years, 15 from 11 to 14 years, 18 from 14 to 15 years, and 44, 52 and 56 at 15+-, 16-and 17-years respectively. The corresponding figures for girls were approximately 12%,/ from 5 to 11 years, 14°o at 11 to 13 years, 12O% at 13 to 15 years, and 31, 43 and 440% at 15-, 16-and 17-years respectively.The research was made on 1,730 pupils, there being rather more boys than girls. The data for the two sexes were recorded separately.It was decided to select a few schools with large numbers of pupils extending over a wide age ra...
