Starting the day with a hot cup of caffeinated coffee or tea may sound divine to some, but it could have negative impacts for the children of people who are pregnant, according to a new study.

Children who were exposed to small amounts of caffeine before birth were found on average to be shorter than the children of people who did not consume caffeine while pregnant, according to the study published Monday in JAMA Network Open.

Children of parents who consumed caffeine while they were in the womb were shown to be shorter in stature at age 4 than those whose parents did not — and the gap widened each year through age 8, according to lead author Dr. Jessica Gleason, a perinatal epidemiologist.

“To be clear, these are not huge differences in height, but there are these small differences in height among the children of people who consumed caffeine during pregnancy,” said Gleason, who is a research fellow at Eunice Kennedy Shriver National Institute of Child Health and Human Development.

The American College of Obstetricians and Gynecologists currently recommends limiting caffeine consumption to less than 200 milligrams per day while pregnant.

Caffeine consumption not safe during pregnancy, new study says. Some experts disagree

For context, a mug of caffeinated tea typically has about 75 milligrams of caffeine, a mug of instant coffee has about 100 milligrams and a mug of filtered coffee has about 140 milligrams, according to the Cleveland Clinic. And even chocolate has about 31 milligrams of caffeine.

But the differences found in the most recent study were found even in the children of parents who drank less than half a cup of coffee per day while pregnant — well below the current guidelines, Gleason said.

It’s not clear whether this study effectively shows causation between maternal caffeine consumption and child height, according to Dr. Gavin Pereira, a professor of epidemiology and biostatistics at Curtin University in Australia. Pereira was not involved in the study.

“The correlation observed in this study can be explained by the existence of a common cause of both caffeine consumption and growth restriction e.g., poverty, stress, and dietary factors,” said Pereira in a statement to the Science Media Centre.

Even small amounts of caffeine may impact a fetus in utero, accoring to the study.

If shorter height in early childhood were to persist into adulthood, there would be a chance those children could face the risk of poor cardiometabolic outcomes, such as heart disease and diabetes, which are associated with smaller stature.

But there is still no way to know if the difference would persist into adulthood, and studies like this that focus on population outcomes are no reason for individual families to panic, Gleason said.

These population-level trends should instead be taken together with other research for organizations to reassess their recommendations, Gleason said.

In the past, there were inconsistent studies regarding whether consuming caffeine during pregnancy impacted the fetus, but the evidence has come together in recent years, Gleason said.

A 2015 meta-analysis that reviewed all of the existing research found there is a dose response association between consumption of caffeine and smaller birth size. And a 2020 study revealed there is no safe level of caffeine for a developing fetus.

Even without the panic that Gleason cautioned against, some people might want to cut back on caffeine — and then find that it’s easier said than done.

Remember, caffeine is found in coffee, tea, soft drinks, energy drinks and shots, as well as cocoa and chocolate. It’s also present in fortified snack foods, some energy bars and even some pain medications.

The caffeine 'detox': How and why to cut back on your daily fix

A 2016 Johns Hopkins University study found that it was helpful when individuals identified situations or moods in which they are most likely to crave caffeine so they could avoid situations that trigger cravings, especially during the first few weeks of modifying caffeine use. Caffeine drinkers could also have a plan for when cravings occur, like taking a five-minute relaxation break involving deep-breathing exercises.

Remember to always discuss any major lifestyle or dietary changes with your health care provider first, as changes may affect your mood or medical conditions.

Moderate daily caffeine intake during pregnancy may lead to smaller birth size

Pregnant women who consumed the caffeine equivalent of as little as half a cup of coffee a day on average had slightly smaller babies than pregnant women who did not consume caffeinated beverages, according to a study by researchers at the National Institutes of Health. The researchers found corresponding reductions in size and lean body mass for infants whose mothers consumed below the 200 milligrams of caffeine per day — about two cups of coffee — believed to increase risks to the fetus. Smaller birth size can place infants at higher risk of obesity, heart disease and diabetes later in life.

The researchers were led by Katherine L. Grantz, M.D., M.S., of the Division of Intramural Population Health Research at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development. The study appears in JAMA Network Open.

“Until we learn more, our results suggest it might be prudent to limit or forego caffeine-containing beverages during pregnancy,” Dr. Grantz said. “It’s also a good idea for women to consult their physicians about caffeine consumption during pregnancy.”

Previous studies have linked high caffeine consumption (more than 200 milligrams of caffeine per day) during pregnancy to infants being small for their gestational age (stage of pregnancy) or at risk for intrauterine growth restriction—being in the lowest 10th percentile for infants of the same gestational age. However, studies on moderate daily caffeine consumption (200 milligrams or less) during pregnancy have produced mixed results. Some have found similar elevated risks for low birth weight and other poor birth outcomes, while others have found no such links. The current study authors noted that many of the earlier studies did not account for other factors that could influence infant birth size, such as variation in caffeine content of different beverages and maternal smoking during pregnancy.

For their study, the authors analyzed data on more than 2,000 racially and ethnically diverse women at 12 clinical sites who were enrolled from 8 to 13 weeks of pregnancy. The women were non-smokers and did not have any health problems before pregnancy. From weeks 10 to 13 of pregnancy, the women provided a blood sample that was later analyzed for caffeine and paraxanthine, a compound produced when caffeine is broken down in the body. The women also reported their daily consumption of caffeinated beverages (coffee, tea, soda and energy drinks) for the past week—once when they enrolled and periodically throughout their pregnancies.

Compared to infants born to women with no or minimal blood levels of caffeine, infants born to women who had the highest blood levels of caffeine at enrollment were an average of 84 grams lighter at birth (about 3 ounces), were .44 centimeters shorter (about .17 inches), and had head circumferences .28 centimeters smaller (about .11 inches).

Based on the women’s own estimates of the beverages they drank, women who consumed about 50 milligrams of caffeine a day (equivalent to a half cup of coffee) had infants 66 grams (about 2.3 ounces) lighter than infants born to non-caffeine consumers. Similarly, infants born to the caffeine consumers also had thigh circumferences .32 centimeters smaller (about .13 inches).

The researchers noted that caffeine is believed to cause blood vessels in the uterus and placenta to constrict, which could reduce the blood supply to the fetus and inhibit growth. Similarly, researchers believe caffeine could potentially disrupt fetal stress hormones, putting infants at risk for rapid weight gain after birth and for later life obesity, heart disease and diabetes.

The authors concluded that their findings suggest that even moderate caffeine consumption may be associated with decreased growth of the fetus.

Is it possible for pregnant women to have coffee? TEA.RU

Coffee is, without a doubt, one of the most popular beverages that people drink almost all over the world. This is an axiom that does not require proof. For many of us, coffee has long become a tradition, and for some, it is an integral part of our lifestyle. There are people among us who cannot imagine the morning without a cup of strong aromatic drink. If we don’t get the “next dose” of caffeine in the morning, it seems to us that the world around us has lost its colors, the mood is hopelessly spoiled, and in general the day didn’t work out initially. nine0003

According to statistics, women drink coffee more often than the strong half of humanity. And then the day comes when a woman finds out that she is pregnant. For many, the question immediately arises as to whether it is possible to drink coffee during pregnancy, how an invigorating drink can affect the health of the child and mother. Is it possible to drink coffee during pregnancy - this is a rather difficult question that has long been of concern to scientists around the world. Opinions on this matter are very different, many scientists study the use of coffee during pregnancy. Unfortunately, there is still no clear answer to this question. But there are certain studies, the data of which will help to understand this issue. nine0003

If we delve deeper into this problem, there are many more questions:

• Is it possible for pregnant women to drink natural coffee or is it better to give preference to an instant drink?
• What kind of coffee can pregnant women drink, and in what cases?
• Should coffee be avoided early in pregnancy or is it necessary later?
• If there is a ban on this drink, why not coffee during pregnancy?
• How much coffee can pregnant women, if the doctor allows? nine0003

And these are far from all the questions that a woman asks herself when she finds out about her “interesting position”. After all, many do not want to give up the morning charge of vivacity, but not a single woman would definitely want to harm the unborn baby, which is natural. So, pregnancy and caffeine - let's try to figure it out.

Coffee during pregnancy: yes or no

The question of whether it is possible to drink coffee during pregnancy can only be answered by a doctor who observes her. The fact is that coffee as such has some “contraindications”. Both in early pregnancy and later, and indeed for women, even if they are not in a “special position”, coffee is not useful if:

• history of chronic diseases of the gastrointestinal tract, such as gastritis, hyperacidity, peptic ulcer, and others;
• there is a tendency to high blood pressure, which is already characteristic of pregnant women due to natural physiological reasons;
• Pregnancy occurs during the hot summer months, as drinking caffeinated drinks can lead to dehydration.
• coffee in early pregnancy is contraindicated if a woman has early toxicosis, accompanied by dizziness and nausea; nine0009 • a lady "in position" was diagnosed with high cholesterol levels in the blood and in some other conditions.
Thus, drinking or not drinking coffee can be decided only after the pregnant woman is fully examined and registered for pregnancy. Timely early visit to the doctor is the key to the health of both mother and baby.

Examination will allow you to choose the way of life that will be as healthy as possible and contribute to the easy bearing of a child at the very beginning of the journey. The effect of coffee on pregnancy can be different, depending on the general health of the expectant mother and some other factors. nine0003

Can I drink instant coffee during pregnancy?

What is instant coffee? Good instant coffee is prepared using sublimation processes and other technologies from natural coffee. The result is a drink rich in micro and macro elements, beneficial nutrients and other compounds. This coffee has all the useful qualities of the original product, polished taste and aroma.

It is worth noting that instant coffee, in comparison with natural coffee, has a lower caffeine content. Accordingly, if there are no contraindications, then instant coffee is possible for pregnant women, but without much fanaticism. If 1 cup a day will not hurt the expectant mother and baby, then 5-6 cups of instant coffee during pregnancy are strongly not recommended by specialists. nine0003

Natural coffee during pregnancy

According to research, natural coffee contains 30-40% more caffeine than its soluble counterparts. Because of this, natural coffee has a more pronounced effect on the nervous system of the human body, has a pronounced stimulating effect and can affect the development of the fetus.

Scientists have conducted a number of studies on the long-term effects of coffee on pregnancy. In the course of these studies, it was found that natural coffee during gestation affects the formation of certain brain structures, which can lead to behavioral abnormalities. Such deviations may not appear immediately, not in infancy, but at the age of 9-10 years.

This may be hyperactivity or even aggressive conduct of the child. There is also evidence that in the future a child whose mother abused caffeine-rich drinks during pregnancy is prone to the development of malignant hypertension and various metabolic disorders.

If the pregnancy proceeds without complications, and there are no additional contraindications, then natural coffee in a volume of up to 200 ml is acceptable and does not harm either the mother or the fetus. Can pregnant women drink coffee with milk? Definitely yes! And the more milk you add to your usual drink, the more benefit and less harmful effects on the body of the mother and fetus. nine0003

Can I drink decaffeinated coffee during pregnancy?

We have already said that there are cases when coffee during pregnancy is strictly contraindicated. In this case, many coffee drinkers mistakenly assume that decaffeinated coffee can be an alternative. Such a drink is in the assortment of almost every specialized store. Moreover, sellers often recommend such a product to women "in position."

Please note! Doctors do not categorically recommend using decaffeinated coffee, since, among other things, such a product contains substances in large enough quantities that are in no way useful when carrying a fetus:
• essential oils;
• fineness;
• resins;
• cafestol, etc.
These substances are able to very quickly "wash out" calcium from the body of a woman, which is so necessary for the formation of the bones of the fetal skeleton. Thus, decaffeinated coffee during pregnancy is not the best solution and not at all a harmless drink. Its amount should not exceed 1 cup per day if your doctor has allowed you.

When can pregnant women drink coffee? nine0017

In some cases, it is worth noting in fairness, pregnant women can drink coffee and a drink can even be useful. These are the cases when:
• the expectant mother has a low level of hemoglobin, which is confirmed by the results of laboratory tests;
• with confirmed iron deficiency anemia;
• with chronic hypotension, that is, if a pregnant woman has low blood pressure;
• there are some deviations in cardiac activity that require correction. nine0009 In this case, the ideal option is latte during pregnancy. It is better to cook it like espresso from a coffee machine, to which a large amount of natural milk is added, which replenishes the deficiency of calcium, potassium and other substances useful for the body of the pregnant woman and the fetus.

How coffee affects pregnancy is still being studied by many scientists, and each time more and more contradictory data are found. It follows from this that there is no complete picture of how coffee affects pregnancy in modern medical science. Is coffee allowed during pregnancy is a question that only your doctor can answer, but in this case you yourself must realize and take full responsibility for all possible consequences. nine0009 Why take risks if herbal teas, drinks made from natural berries and many other tasty and healthy things can be useful for the health of the unborn baby. A habit is a powerful thing, but it differs in that it can be abandoned at any time if it becomes irrelevant or harmful. And tea ceremonies can be an excellent alternative for you, because it is not only tasty, but also very interesting.

is it still possible or not?

Researchers confirm that drinking coffee during pregnancy does not pose serious risks to the mother and her unborn child. nine0003

An international team of scientists has determined that daily coffee consumption does not increase the risk of preterm birth, miscarriage or stillbirth.

Researchers say that pregnant women can safely drink coffee at least every day without fear of side effects. But it is still necessary to limit its consumption to the recommended rate.

Recall that WHO recommends that pregnant women consume no more than 300 mg of caffeine per day. In the United States and some European countries, the maximum dose of caffeine is even less - 200 mg per day. nine0003

In general, these recommendations are equivalent to 1-3 cups of coffee per day, although the amount of caffeine in different coffee drinks can vary greatly.

Previous recommendations were based on observational studies. They make it difficult to separate coffee consumption from other risk factors such as smoking, alcohol or poor diet.

The authors of the new study wanted to find out whether coffee itself actually increases the risk of adverse pregnancy outcomes. nine0003

They relied on a study that found that a certain set of genetic variants influences how much coffee we drink.

Of course, the researchers couldn't ask women to drink the prescribed amount of coffee during pregnancy to assess health risks. This would be highly unethical.

Instead, they used genetic analysis to mimic a randomized controlled trial. Let us explain that this is the highest quality standard of scientific work in the view of modern scientists. nine0003

The researchers used a method called Mendelian randomization. ( It is named after the eminent biologist Gregor Mendel. ) Scientists have studied whether eight genetic variants that predict how much a pregnant woman consumes coffee are also associated with birth outcomes.

As a result, genetic analysis showed that women who drank coffee did not have an increased risk of miscarriage, stillbirth or preterm birth.

The researchers emphasize that only certain adverse pregnancy outcomes were considered in their work, and it is possible that caffeine intake may affect some other important aspects of fetal development.
