Variation in height and weight in the Norwegian population.

Since 1962, as an international collaborative project, studies have been in progress of disease among migrants and native populations in Great Britain, Norway, and the United States. The back ground for the first studies and data on various demographic characteristics, residential history, smoking history, and cardiorespiratory symptoms for migrants and native-born in the United States have been published elsewhere (Reid, 1966; Reid et al., 1966). For the men in the sample of Nor wegian-born residents of the United States and in the study groups in Norway additional data have been collected on dietary habits. The items of information that one attempted to obtain for all individuals under study included height and weight. Reasons for considering height and weight were the known and suspected association of body size, as indexed by height, weight, or a function of the two, with morbidity and mortality from a number of diseases and the variation of body size with living conditions and habits of the individuals.
