Abstract The objective of this study was to investigate risks of physical activity at work by pregnancy trimester, including the effects on head and abdominal circumference. At 34 weeks of gestation 1327 expectant mothers participating in a wider cohort study were interviewed on their activities (working hours, shift work and work postures) in jobs held at each of 11, 19 and 34 weeks of gestation, and subsequently ascertained birth outcomes (preterm delivery, small for gestational age (SGA) and reduced head or abdominal circumference). Risk of preterm delivery was elevated nearly threefold in women whose work at 34 weeks entailed trunk bending for >1h/day. Small head circumference was more common in babies born to women who worked for >40h/week. However, no statistically significant associations were found with SGA or small abdominal circumference, and preterm delivery showed little association with long working hours, lifting, standing or shift work.
