  • Uncertainties in designation of age at menarche in the nineteenth century

    Open Access•Peter J Helm, Peter Helm et al.•ARTICLE•Annals of Human Biology•1987

    The earliest Danish study of mean age at menarche by Ravn (Fenger 1850) is analysed with special reference to age recordings and their subsequent groupings into age-classes. Uncertainties of interpretation of the age designations are discussed, and it is argued that, in all probability, mean age at menarche was 17 years in the samples of Danish women born around 1820, rather than below 16 years as believed previously

  • Skeletal maturity in Danish schoolchildren assessed by the TW2 method

    Open Access•Sven Helm•ARTICLE•American Journal of Physical…•1979•References: 9

    Skeletal maturity was assessed from hand‐wrist radiographs in a sample of 3,817 Danish schoolchildren aged 7 to 18 years using the new version of the bone‐specific Tanner‐Whitehouse scoring system, the TW2 method. In most of the age groups in both sexes the distributions of the bone maturity scores displayed marked departures from normality; percentiles for the scores were therefore counted from the raw data. On the average, over the total age ra…
