Epidemiology: March 1995

We conducted a population-based case-control study in women in high-risk manufacturing occupations to examine occupational injury and its association with possible risk factors inside and outside the work place. The primary hypothesis was that women with young children are at greater risk of occupational injury than are women without young children, owing to the responsibility and fatigue associated with raising young children. The odds of reported injury was 2.9 times greater in women with a child less than 6 years of age than in women without children less than age 6 [odds ratio (OR) = 2.9; 95% confidence interval (CI) = 1.5–5.6]. The same effect was not observed for women with older children. Other predictors of injury were a history of previous injury (OR = 2.7; 95% CI = 1.8–3.9) and a body mass index greater than or equal to 25 (OR = 1.6; 95% CI = 1.08–2.4). We found small or zero effects for age, years of work experience, total number of children at home, ethnicity, marital status, and shift worked. These findings indicate that factors outside the work place, such as the presence of young children at home, may increase the risk of occupational injury for women employed in manufacturing jobs.
