Abstract
Reproductive health data were collected for a sample of 1,035 married nonsmoking women workers in three textile mills in Anhui, China. Over two thirds of the workers were on rotating workshifts with an 8 day cycle during their pregnancy, providing an opportunity to examine the effects of these cycles on preterm birth and birth weight. These women worked an 8 day cycle with shift changes every 2 days throughout their pregnancy. Mean gestational age was 38.8 and 39.0 weeks for shift and regular schedule workers, respectively. The mean birth weights were 3248 grams and 3338 grams for rotating shift workers and regular schedule workers, respectively. The proportions of preterm birth and low birth weight, respectively, were 20% and 9% for shift workers and 15% and 6% for regular schedule workers. This association remained significant when the analysis was restricted to production workers or first order live births. The authors conclude that there was a significant association of rotating shiftwork with low birth weight and preterm birth in a sample of women textile workers.
