Drinking coffee during pregnancy ups obesity risk in kids: study

Press Trust of India  |  London 

Mothers-to-be, take note! Drinking just one or two cups of daily during can increase the risk of your child growing up to be or obese, scientists say.

While the study published in does not clearly show if caffeine is the direct cause of the excess weight, but the relationship, alone, has caused researchers to encourage increased caution.

"There may be good cause to increase the restriction of the recommended maximum of three cups of per day. Caffeine is not a that needs to be consumed," said Verena Sengpiel, at

Researchers, including those from Norwegian Institute of Public Health, studied information on 50 943 pregnant women, in one of the world's largest surveys of pregnant women, the Norwegian Mother and Child Cohort Study (MoBa).

The results show that children born to mothers who consumed caffeine during are at greater risk of being at preschool and school ages.

Children were followed until eight years of age. Being in childhood has previously been linked to increased risk of and Type 2 later in life.

For example, at age five, the share of children who were overweight or obese was five percent greater in the group whose mothers had the highest caffeine consumption in the study, compared to those whose mothers had the lowest caffeine consumption.

The association between caffeine consumption during and the risk of excess growth and overweight or in children could also be seen in women who had followed the recommended amount for pregnant women.

According to Sweden's National Food Agency, pregnant women should not consume more than 300 milligrams of caffeine per day, which is equivalent to three cups of or six mugs of black tea.

The results of the current study are supported by at least two other studies; however, these included significantly fewer subjects and fewer sources of caffeine. This time, coffee, tea, chocolate, and other sources were included.

In general, the gestational environment is viewed as being important in the turning off and on of genes and metabolic programming for the duration of life. Previous animal studies, where embryos were exposed to caffeine in the womb, were also followed by excess growth and in the offspring.

"Even if more studies are needed before we can say what this finding really means, caffeine is a substance that you can choose to reduce consumption of or completely refrain from during pregnancy," said Sengpiel.
