Babies born smaller if mothers stand at work
Standing for prolonged periods during pregnancy may curb the growth of the baby in the womb, research suggests.
Pregnant teachers, childcare workers and women that work in sales are among those whose babies are likely to have smaller heads when they are born -- implying a slower growth rate.
The study, published online in 'Occupational and Environmental Medicine', examined 4,680 mothers-to-be from early pregnancy onwards.
The women were surveyed on their work conditions and the physical demands of their jobs.
