Consuming caffeinated drinks is a risk factor for pregnancy
Caffeine consumption by both parents before pregnancy has a significant impact on the risk of miscarriage. In a recent study, scientists from the National Institutes of Health (NIH) and Ohio State University in Columbus found that consuming two or more drinks containing caffeine a day in advance of pregnancy significantly reduced the likelihood of a successful pregnancy. However, a daily vitamin intake in mothers can significantly reduce the risk of miscarriage, the researchers report on their current study results.

According to the latest study results, both caffeine consumption by mothers and caffeine intake by fathers prior to conception have a significant impact on the course of pregnancy. The scientists report that the chances of a successful pregnancy are significantly reduced if you consume at least two drinks containing caffeine per day. The results of their investigations were published in the specialist magazine “Fertility and Sterility”.

Data from 344 pairs evaluated
As part of their study, the scientists from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and Ohio State University evaluated the data from 344 couples and the respective course of pregnancy. The pregnancies were single and the couples were observed for a period of seven weeks after conception. The analyzed data came from the so-called LIFE study, which was carried out to examine relationships between fertility, lifestyle and exposure to environmental chemicals.

Older women with significantly more miscarriages
For the couples considered, the researchers analyzed lifestyle factors such as cigarette consumption, the intake of caffeinated drinks, the consumption of organic food and the intake of vitamins. Here they looked for possible connections with the course of pregnancy. The scientists found various factors that correlated with an early termination of pregnancy. Of the 344 pregnancies, a total of 98 ended in miscarriage (28 percent) and, for example, women over the age of 35 were statistically almost twice as likely to have miscarriages (hazard ratio 1.96) as in younger women. Although the study was not designed to provide conclusive explanations for the cause-and-effect relationship, the advanced age of sperm and egg or the cumulative exposure to environmental pollutants in older couples may be the cause of the increased risk of miscarriage, the researchers report .

Two caffeinated drinks a day significantly increase the risk of miscarriage
According to the NICHD, an almost equally clear connection was found between the likelihood of miscarriage and the caffeine consumption of parents-to-be (hazard ratio 1.74 women: 1.73 men). "Both the male and the female consumption of more than two drinks containing caffeine per day were associated with an increased risk ratio," the scientists report. A successful "pregnancy is more likely to fail if a woman and / or her partner drinks more than two caffeinated drinks a day during the weeks before conception," warned the study authors. In previous studies, a link between the caffeine consumption of women in early pregnancy and the risk of miscarriage had already been demonstrated.

Vitamin intake lowers the risk of miscarriage
"Our results provide useful information for couples who are planning to become pregnant and want to minimize the risk of early termination," explains the study's first author, Dr. Germaine Buck Louis from NICHD. In addition, it becomes clear that the male partner also plays a role. Their caffeine consumption was just as much associated with the risk of an early termination of pregnancy as the caffeine intake of the women, the researchers report. However, the scientists were also able to identify lifestyle factors in their evaluations that were associated with a significantly reduced risk of miscarriage. This effect was particularly pronounced in the daily vitamin intake. Such a prior to pregnancy reduced the risk of termination of pregnancy by 55 percent and a reduction of 79 percent could be determined when taking vitamins in the first weeks of pregnancy, Dr. Buck and colleagues in the NICHD press release on the latest study results.
