In a recent study of social,
economic and health characteristics of expectant fathers, advanced age was defined as 35–39 years and very advanced ≥40 years of age (Vika Nilsen et al., 2013). For the purpose of the present study, we found it reasonable to divide the sample by the breakpoints for the lower and upper quartiles for age, thus defining young men as r27
years (n=188), average aged men as 28–33 years (n=389) and men of advanced age as ≥34 years (n=200).
