Résumé :	[BDSP. Notice produite par INIST Q3R0xmP5. Diffusion soumise à autorisation]. Objectives. This study examined the change in heritability of adult body height across birth cohorts inFinland. Methods. In 1981, cross-sectional questionnaires were completedby 10 968 twin pairs born befor factors was estimated via genetic modeling. Results. Heritability increased fron the cohort bon befor 1929 (0.76,95% confidence interval [CI]=0. - (, 95% CI=0.55,0.77 in women) ti that bon in 1947 through 1957 (0.81,95% CI=0.73,0.87 in men ; 0.82,95% CI=0.75,0.89 in women). Conclusions. Heritability of height increased across Finnish birth cohorts born in the first half of this century and leveled off after Word War II. Environmental factors, compared with genetic factors, appear to be more important among women than men.
