However, claiming that coffee during pregnancy can directly lead to a specific reduction in a child's height by an inch is misleading and oversimplified.The impact of caffeine consumption during pregnancy on a child's growth and development is a complex issue and can be influenced by various factors including the amount of caffeine consumed, other lifestyle factors, genetics, and overall maternal health.It's important for pregnant women to consult with their healthcare provider about their caffeine intake and any other lifestyle choices that may affect their pregnancy. Generally, moderate caffeine consumption (around 200mg per day, or about one 12-ounce cup of coffee) is considered safe during pregnancy for most women, but individual tolerance levels may vary.
Drinking just half a cup of coffee per day during pregnancy can knock nearly an inch off a child's height, an official study suggests.Minors born to women who consumed 50mg of caffeine each day were 2cm (0.8in) smaller than their peers by the age of eight.The finding remained even after adjusting for other factors that affect a child's height — including their mother's age, smoking status and income.Researchers say the results — based on an analysis of 2,500 boys and girls across the US — show expectant mothers should abstain from coffee entirely.Current US guidelines recommend pregnant women limit their daily intake to about 200mg. The average 8oz coffee contains about 100mg of caffeine.Caffeine is thought to constrict blood vessels in the womb and placenta, which could reduce the blood supply to the fetus and stunt growth.The study is the first of its kind to use blood tests to measure pregnant women's caffeine intake rather than surveys, which are less reliable.
