OBJECTIVES: The Danish National Birth Cohort (DNBC) was used to examine
pregnancy outcomes among female hairdressers and neurodevelopment in their
offspring. METHODS: A population-based cohort study was conducted of 550
hairdressers and 3216 shop assistants (reference group) by using data from the
Danish National Birth Cohort between 1997 and 2003. Information on job
characteristics was reported by the women in the first interview (around 17
weeks of gestation). Pregnancy outcomes were obtained by linkage to the national
registers. Developmental milestones were reported by the mother at the fourth
interview, when the child was approximately 19 months old. Cox regression was
applied to analyze fetal loss and congenital malformation. Logistic regression
was used to analyze other pregnancy outcomes and developmental milestones.
RESULTS: We found no significant differences in fetal loss, multiple births,
gender ratio, preterm birth, small-for-gestational age, congenital
malformations, or achievement of developmental milestones among the children of
hairdressers and shop assistants. CONCLUSIONS: The results do not indicate that
children of hairdressers in Denmark currently have a high risk of fetal
impairment or delayed psychomotor development.
