Abstract
), where h is the predicted from the model mean height, b 1 = 180.16 (95% C.I. 179.33 - 180.98, p<0.001) and represents the upper asymptote namely, the maximum mean height attained after theoretically infinite time, b 2 =0.823 (95% C.I. 0.813 - 0.833, Abstract Background: Final height in boys is considered to be achieved, most commonly, at the age of 18 years. However, if one looks carefully at various growth charts may notice some increase in the mean height of boys from the age of 18 to 20 years. In this study we aimed at examining final height in a large sample of contemporary conscripts of the Greek Army. Methods: The height of 3038 young men was measured in the year 2006. We explored our data using a lowess curve and after having taken into account its form, we adjusted a proper non-linear regression model to our data. Results: The lowess curve showed an increment in the mean height up to the age of about 23 years whereas, after this age mean height seemed to be stable. The model that described adequately our data was: (h = b 1 (1-b 2 k)), where h is the mean height, b 1 =180.16 (95% C.I.: 179.33 - 180.98, p<0.001), b2=0.823 (95% C.I.: 0.813 - 0.833, p<0.001), and k=age in years. Conclusion: Our study provides a hint against the established notion of growth ceasing at the age of about 18 years, in males.
