Offspring sex ratio among Iranian dentists
Objectives: to assess the impact of the occupational factors on the sex ratio of dentists’ children.
Methods: A randomly selected 501 number of Iranian dentists participated in a telephone interview. The participants were contacted by their mobile number to answer questions about demographic variables (gender, age by year, marriage status), practice-related variables (year of graduation as general or specialist dentist, years of clinical work, working hours, average number of radiograph taken in a day, and spouse’s job), and questions about their children (number of children, gender and date of birth of each child). Kruskal-Wallis test and backward logistic regression served as statistical evaluation.
Results: Of all participated dentists, 71% were men, about two-third were 35-50 year olds, and 89% were married. In total, the dentists had 768 children and about 21% of them had no child. Of all the children, 54% were boys (overall sex ratio=1.17). Offspring sex ratio among male dentists was 1.13 and about the female dentists was 1.50, when both parents were dentists it was 1.44 . Higher percentages of boys were prevalent among female dentists, younger dentists, and general dental practitioners (P<0.008).
Conclusions: Demographic and practice related factors showed some impact on proportion of both sexes among the children of dentists in this study. However, the result needs to be evaluated in other studies.
