Premature babies have more problems at six

Children born between 34 and 36 weeks into their mothers' pregnancies could be at greater risk of developing cognitive and emotional problems. Researchers from Michigan State University studied a group of children born between 1983 and 1985 and compared at what stage during their mothers' pregnancies they were born to information collected when they were six. The children born between 34 and 36 weeks had lower levels of cognitive performance and higher levels of behavioural problems even after accounting for socioeconomic factors and maternal IQ.
