Fertility in a prospective Canadian cohort of women in the welding and electrical trades.

ABSTRACT:

Objectives

To determine the effects of work exposures on fertility in tradeswomen.

Methods

Women apprenticed in welding and electrical trades across Canada were recruited (2011-2017) to a prospective cohort and contacted every 6 months for up to 5 years. At each contact, participants provided information on conceptions, sexual activity, birth control and pregnancy attempts. Occupational exposures to ergonomic factors and, for welders, to metals and dust in welding fume were estimated from task-specific questionnaires. The OR of clinical infertility for work in welding was estimated. Time ratios (TR), relative times to conception, were estimated for first pregnancy in an accelerated failure time (AFT) regression with a log normal distribution of the hazard, to assess the rela
