Pregnant women who consume at least 200 mg of caffeine daily — that is, about two cups of coffee — are more likely to give birth to children who become overweight, according to a prospective study in BMJ Open.

Norwegian researchers studied over 50,000 mother-child pairs. The mothers completed food-frequency questionnaires during pregnancy, from which caffeine intake was estimated, and the children's height and weight were measured several times until age 8 years.

Among the findings:

• Excess growth during infancy increased as maternal caffeine intake increased.
• Compared with low caffeine intake in pregnancy (<50 mg/daily), high intake (200–299 mg/day) conferred a 17% increased risk for the child being overweight at age 3 years, and very high intake (300 mg/day or more) conferred a 44% increased risk.
• High and very high caffeine intake also conferred significantly increased risks for overweight at age 5 years.

The researchers conclude, "Our findings support the recommendation to limit caffeine intake during pregnancy (<200 mg/day)."
