Makrosomia płodu
Zapobieganie i profilaktyka

Makrosomia płodu definiowana jest jako masa urodzeniowa przekraczająca 4000 g i wiąże się ze zwiększonym ryzykiem powikłań okołoporodowych u matki i noworodka. Kluczowymi modyfikowalnymi czynnikami ryzyka są: nadwaga i otyłość matki przed ciążą, nadmierny przyrost masy ciała w ciąży, nieprawidłowa kontrola glikemii u kobiet z cukrzycą przedciążową lub ciążową (GDM), nieodpowiednia dieta oraz brak aktywności fizycznej. Zalecany przyrost masy ciała wynosi 11-16 kg dla kobiet z prawidłową masą ciała przed ciążą, a u kobiet z nadwagą lub otyłością powinien być indywidualnie dostosowany i mniejszy. Ścisła kontrola glikemii, w tym stosowanie diety i insulinoterapii lub metforminy, może zmniejszyć ryzyko makrosomii, zwłaszcza gdy HbA1c w 24-28 tygodniu ciąży jest utrzymywane poniżej 5,5%. Dieta o niskim indeksie glikemicznym oraz regularna aktywność fizyczna w ciąży również przyczyniają się do ograniczenia przyrostu masy ciała i ryzyka makrosomii.

Prewencja makrosomii płodu – wprowadzenie

Makrosomia płodu (z łac. fetal macrosomia) definiowana jako masa urodzeniowa przekraczająca 4000 g, stanowi istotny problem położniczy, który wiąże się ze zwiększonym ryzykiem powikłań zarówno u matki, jak i u noworodka. Zapobieganie makrosomii jest w dużej mierze uzależnione od prawidłowej identyfikacji czynników ryzyka oraz wdrożenia odpowiednich działań profilaktycznych.12 Chociaż całkowite zapobieganie makrosomii płodu nie zawsze jest możliwe, istnieje szereg strategii, które mogą zmniejszyć ryzyko jej wystąpienia.34

Czynniki ryzyka podlegające modyfikacji

Identyfikacja modyfikowalnych czynników ryzyka makrosomii płodu stanowi podstawę działań profilaktycznych. Do najważniejszych czynników podlegających interwencji należą:15

156

Strategie zapobiegania makrosomii płodu

Planowanie ciąży i konsultacje przedkoncepcyjne

Konsultacje przedkoncepcyjne stanowią ważny element profilaktyki makrosomii płodu, szczególnie dla kobiet z czynnikami ryzyka.4 Kobietom z otyłością zaleca się:7

  • Konsultację z lekarzem przed planowaną ciążą
  • Skierowanie do dietetyka lub specjalisty leczenia otyłości w celu osiągnięcia prawidłowej masy ciała przed zajściem w ciążę
  • Omówienie indywidualnych czynników ryzyka i planu postępowania

48

Niektóre badania sugerują, że chirurgia bariatryczna u kobiet z otyłością klasy 2 lub 3 przed ciążą może zmniejszyć ryzyko makrosomii nawet o 50%. American College of Obstetricians and Gynecologists (ACOG) zaleca rozważenie korzyści i ryzyka chirurgii bariatrycznej przed ciążą u pacjentek z ciężką otyłością.5

Kontrola masy ciała przed i podczas ciąży

Odpowiedni przyrost masy ciała podczas ciąży jest istotnym elementem profilaktyki makrosomii płodu:49

  • Dla kobiet z prawidłową masą ciała przed ciążą zalecany przyrost wynosi 11-16 kg (25-35 funtów)
  • Kobiety z nadwagą lub otyłością przed ciążą powinny mieć indywidualnie ustalony, mniejszy przyrost masy ciała
  • Regularne monitorowanie masy ciała podczas ciąży
  • Współpraca z lekarzem w celu ustalenia optymalnego przyrostu masy ciała dostosowanego do indywidualnej sytuacji pacjentki

410

Badania pokazują, że nadmierna masa ciała przed ciążą oraz nadmierny przyrost masy ciała podczas ciąży są niezależnymi czynnikami ryzyka makrosomii płodu, które można modyfikować poprzez odpowiednią interwencję żywieniową.911

Kontrola glikemii u kobiet z cukrzycą

Kontrola glikemii jest jednym z najważniejszych elementów zapobiegania makrosomii płodu, szczególnie u kobiet z cukrzycą przedciążową lub cukrzycą ciążową:1213

  • Ścisła kontrola glikemii podczas ciąży z zastosowaniem diety i insuliny może zmniejszyć częstość występowania makrosomii u kobiet z cukrzycą
  • Regularne pomiary stężenia glukozy we krwi
  • Współpraca z zespołem diabetologicznym
  • Odpowiednie leczenie farmakologiczne – niektóre badania sugerują, że stosowanie metforminy w kontroli glikemii może być bardziej skuteczne niż sama insulina w zapobieganiu makrosomii płodu (o 20% niższe ryzyko w porównaniu do insulinoterapii)

5121415

Badania wykazały, że w przeszłości około 60% noworodków urodzonych przez matki z cukrzycą przekraczało 95. percentyl masy ciała dla wieku ciążowego, jednak dzięki poprawie leczenia cukrzycy ciążowej odsetek ten zmniejszył się obecnie do 20-30%.16

Wykazano również, że wysokie stężenie hemoglobiny glikowanej (HbA1c ≥5,5%) w 24-28 tygodniu ciąży jest istotnie związane z ryzykiem makrosomii lub urodzenia dziecka dużego w stosunku do wieku ciążowego (LGA) u kobiet z cukrzycą ciążową.1718

Dieta o niskim indeksie glikemicznym

Stosowanie diety o niskim indeksie glikemicznym podczas ciąży jest prostym, bezpiecznym i skutecznym środkiem poprawiającym homeostazę glukozy u matki oraz mogącym ograniczyć przyrost masy ciała.1920

Badanie ROLO (Randomised cOntrol trial of LOw glycaemic index diet) wykazało, że chociaż dieta o niskim indeksie glikemicznym nie zmniejszyła częstości występowania noworodków dużych w stosunku do wieku ciążowego w grupie ryzyka, to miała pozytywny wpływ na:1921

  • Przyrost masy ciała podczas ciąży (znacząco mniejszy)
  • Nietolerancję glukozy u matki (mniejsza częstość występowania)
  • Ogólną homeostazę glukozy

1921

Nawet pojedyncza formalna sesja dietetyczna w małej grupie we wczesnej ciąży może być wystarczająca do poprawy odżywiania matki i korzystnych efektów metabolicznych.19

Aktywność fizyczna podczas ciąży

Badania wykazują, że odpowiednia aktywność fizyczna podczas ciąży może zmniejszyć ryzyko makrosomii płodu:1222

  • Indywidualnie dostosowany program ćwiczeń może znacząco zmniejszyć częstość występowania makrosomii (3,73% vs 13,61% w grupie kontrolnej)
  • Aktywność fizyczna zmniejsza ryzyko nadmiernego przyrostu masy ciała podczas ciąży niezależnie od BMI sprzed ciąży
  • Kobiety, które nie ćwiczą podczas ciąży, mają 2,5 razy większe prawdopodobieństwo urodzenia noworodka z makrosomią
  • Regularna aktywność fizyczna zmniejsza ryzyko makrosomii poprzez zmniejszenie przyrostu masy ciała podczas ciąży

222324

Zaleca się, aby wszystkie kobiety w ciąży bez przeciwwskazań wykonywały aktywność fizyczną dostosowaną do ich stanu zdrowia i możliwości, pod nadzorem lekarza prowadzącego.23

Regularne wizyty prenatalne

Regularne wizyty prenatalne pozwalają na monitorowanie przebiegu ciąży i wczesne wykrywanie czynników ryzyka makrosomii:325

  • Możliwość regularnego monitorowania wzrostu płodu
  • Wczesne wykrywanie cukrzycy ciążowej i innych zaburzeń metabolicznych
  • Ocena prawidłowości przyrostu masy ciała matki
  • Możliwość wprowadzenia odpowiednich interwencji w przypadku wykrycia nieprawidłowości
  • Przygotowanie do porodu z uwzględnieniem ryzyka makrosomii

1325

Interwencje położnicze w profilaktyce powikłań makrosomii

W przypadku podejrzenia makrosomii płodu, rozważane są różne opcje postępowania położniczego, jednak ich skuteczność w zapobieganiu powikłaniom jest dyskusyjna:26

Indukcja porodu

Indukcja porodu przed lub około terminu była proponowana jako metoda zapobiegania makrosomii i jej powikłaniom, biorąc pod uwagę, że płód przybiera około 230 g tygodniowo po 37 tygodniu ciąży.2 Jednak badania obserwacyjne sugerują, że indukcja może zwiększać częstość cięć cesarskich bez korzystnego wpływu na wyniki perinatalne.6 Aktualnie nie ma konsensusu co do optymalnego postępowania w przypadku podejrzenia makrosomii płodu.26

Elektywne cięcie cesarskie

Elektywne cięcie cesarskie było proponowane jako sposób na uniknięcie niepotrzebnego porodu i zapobieganie urazom okołoporodowym.2 Jednak trudności w przewidywaniu makrosomii i korzystne wyniki dla większości kobiet, które podejmują próbę porodu siłami natury, sugerują, że konieczne byłoby wykonanie dużej liczby niepotrzebnych cięć cesarskich, aby zapobiec pojedynczemu złemu wynikowi w ciąży powikłanej podejrzeniem makrosomii płodu.2

American College of Obstetricians and Gynecologists (ACOG) zaleca rozważenie cięcia cesarskiego w następujących przypadkach:2728

  • Szacowana masa płodu ≥5000 g u kobiet bez cukrzycy
  • Szacowana masa płodu ≥4500 g u kobiet z cukrzycą

2728

Należy jednak pamiętać, że ultrasonograficzna ocena masy płodu w późnej ciąży jest obarczona znacznym błędem i powinna być stosowana oszczędnie i z jasnymi wskazaniami.28

Profilaktyka długoterminowa

Zapobieganie makrosomii płodu ma znaczenie nie tylko dla zmniejszenia ryzyka powikłań okołoporodowych, ale także dla długoterminowego zdrowia matki i dziecka:2930

  • Przerwanie „błędnego koła” makrosomii płodu i otyłości dziecięcej
  • Zmniejszenie ryzyka nadwagi i otyłości we wczesnym dzieciństwie
  • Redukcja ryzyka zespołu metabolicznego i cukrzycy typu 2 u dzieci w późniejszym życiu
  • Zmniejszenie ryzyka cukrzycy typu 2 u matek po ciąży powikłanej makrosomią

293132

Badania wykazały, że makrosomia płodu może być markerem nadmiernego odżywienia wewnątrzmacicznego i zaburzeń metabolicznych, które mogą predysponować dzieci do nadmiernego przyrostu masy ciała i otyłości w późniejszym życiu.30 Dlatego zapobieganie nadmiernemu odżywianiu wewnątrzmacicznemu i przyrostowi masy ciała podczas ciąży może być obiecującą strategią przerwania międzypokoleniowego cyklu otyłości.3016

Wyzwania i perspektywy w profilaktyce makrosomii płodu

Pomimo postępów w rozumieniu czynników ryzyka i mechanizmów prowadzących do makrosomii płodu, pozostają pewne wyzwania w skutecznym zapobieganiu temu powikłaniu:33

  • Trudności w dokładnym przewidywaniu makrosomii przed porodem
  • Złożoność interakcji między czynnikami matczynymi a płodowymi
  • Optymalny moment i metoda interwencji położniczych w przypadku podejrzenia makrosomii
  • Identyfikacja biomarkerów przewidujących makrosomię

6834

Istnieje potrzeba dalszych badań nad patogenetycznymi cechami rozwoju makrosomii w celu opracowania nowych podejść do jej wczesnego przewidywania i zapobiegania.33 Badania prospektywne mogą pomóc w ocenie długoterminowych efektów interwencji zdrowotnych dla matki i opracowaniu skutecznych strategii profilaktycznych.35

Podsumowanie

Profilaktyka makrosomii płodu powinna koncentrować się na identyfikacji i modyfikacji czynników ryzyka, które są najbardziej podatne na interwencję. Masa ciała matki, przyrost masy ciała podczas ciąży oraz kontrola glikemii to główne obszary, w których możliwe jest wdrożenie skutecznych działań profilaktycznych.1

Kompleksowe podejście do zapobiegania makrosomii powinno obejmować:11

  • Edukację i opiekę żywieniową
  • Aktywność fizyczną dostosowaną do stanu zdrowia matki
  • Wzmocnienie pozycji kobiet w zakresie ich opieki prenatalnej, szczególnie w odniesieniu do przyrostu masy ciała
  • Interwencje dietetyczne
  • Ścisłą kontrolę glikemii u kobiet z cukrzycą
  • Regularne monitorowanie wzrostu płodu

1131

Chociaż makrosomia płodu nie zawsze jest możliwa do przewidzenia i zapobieżenia, wdrożenie powyższych strategii może znacząco zmniejszyć jej częstość występowania oraz związane z nią powikłania matczyne i noworodkowe.34

  • #1 Prediction and prevention of the macrosomic fetus – PubMed
    https://pubmed.ncbi.nlm.nih.gov/22459652/
    Fetal macrosomia is associated with significant maternal and neonatal morbidity. […] Prevention of fetal macrosomia is entirely dependent upon correct identification of those at risk. Maternal weight, gestational weight gain and glycaemic control are the risk factors for fetal macrosomia that are most amenable to intervention, and have potential maternal health benefits beyond pregnancy and childbirth. […] In this review we outline the contemporary evidence for the prediction and prevention of fetal macrosomia, which is indeed a contemporary dilemma.

    Fetal macrosomia, arbitrarily defined as a birth weight of more than 4,000 g (8 lb, 13 oz) complicates more than 10 percent of all pregnancies in the United States. […] Elective cesarean section for suspected macrosomia has been proposed as a way to spare the parturient an unproductive labor and to prevent birth trauma. […] Unfortunately, the difficulties in predicting macrosomia and the favorable outcome for most women who undergo a trial of labor imply that a large number of unnecessary cesarean sections would have to be performed to prevent a single bad outcome in the pregnancy complicated by suspected fetal macrosomia. […] Given that the fetus continues to gain about 230 g (8.1 oz) per week after the 37th week, elective induction of labor before or near term has been suggested to prevent macrosomia and its complications.
  • #3 Fetal Macrosomia: What Is It, Causes & Complications
    https://my.clevelandclinic.org/health/diseases/17795-fetal-macrosomia
    Fetal macrosomia is often unpredictable. The diagnosis is made only after your baby has been weighed after delivery. Babies can be born larger than average with or without any known risk factors. […] Promoting good health and a healthy pregnancy can improve the odds: […] Get regular prenatal care. Frequent visits allow you and your healthcare provider to closely follow your baby’s progress and also give you a chance to ask questions. […] Watch your weight. Your weight before pregnancy matters, as does how much weight you gain while you’re pregnant. […] If you have diabetes, take appropriate steps to manage it. Diabetes before your pregnancy and diabetes that happens during your pregnancy (gestational diabetes) are risk factors for fetal macrosomia.

    https://www.swissmedical.net/en/healtcare-library/con-20372561
    You might not be able to prevent fetal macrosomia, but you can promote a healthy pregnancy. Research shows that exercising during pregnancy and eating a low-glycemic diet can reduce the risk of macrosomia. […] Schedule a preconception appointment. If you’re considering pregnancy, talk with your health care provider. If you’re obese, you might also be referred to another health care provider such as a registered dietitian or an obesity specialist who can help you reach a healthy weight before pregnancy. […] Monitor your weight. Gaining a healthy amount of weight during pregnancy often 25 to 35 pounds (about 11 to 16 kilograms) if you have a normal pre-pregnancy weight supports your baby’s growth and development. Women who weigh more when they get pregnant will have lower recommended pregnancy weight gain. Work with your health care provider to determine what’s right for you.
  • #5 Macrosomia Treatment & Management: Medical Care, Surgical Care, Consultations
    https://emedicine.medscape.com/article/262679-treatment
    Several potentially useful strategies may be helpful in prevention of macrosomia. Note the following: […] In both diabetic mothers and in those with gestational diabetes, tight control during pregnancy with the use of diet and insulin can reduce the frequency of macrosomia. […] Prevention of maternal obesity before pregnancy may reduce the frequency of macrosomia. However, no clinical randomized trials have validated this hypothesis. Obesity is also associated with other morbidities in pregnancy, including higher rates of preeclampsia and cesarean delivery. […] Maggard et al published data on pregnancy outcome from obese women after bariatric surgery. These results showed improvements in pregnancy outcome, including macrosomia, which was reduced by almost 50%. […] Nonetheless, ACOG recommends counseling patients with class 2 or class 3 obesity regarding the risks and benefits of bariatric surgery prior to pregnancy.
  • #6 Management of Suspected Fetal Macrosomia | AAFP
    https://www.aafp.org/pubs/afp/issues/2001/0115/p302.html
    However, observational studies suggest that induction actually increases the cesarean section rate without favorably altering perinatal outcomes. […] The medical literature confirms that prediction of fetal macrosomia is difficult. […] With the exception of optimal blood glucose management in pregnancies complicated by diabetes, little is known about the prevention of macrosomia. […] The association between maternal weight, weight gain during pregnancy and macrosomia has led to a proposal that the optimization of maternal weight before pregnancy and limitation of weight gain during pregnancy would be useful strategies. […] For almost all macrosomic pregnancies including diabetic mothers, previous deliveries with shoulder dystocia, or women considering VBACs, expectant management with vigilance for evidence of fetopelvic disproportion will have optimal results.

    https://www.birthinjuryguide.org/causes/fetal-macrosomia/
    Fetal macrosomia is an unpredictable condition. Sometimes, a diagnosis can only be made at the time of delivery. There are cases where fetal macrosomia occurs for no apparent reason. However, pregnant women can help reduce maternal risk factors by: […] Plan Your Pregnancy: Women who are trying to conceive can reduce the risk of complications like fetal macrosomia by talking to their healthcare provider before conception or early on in the pregnancy. Women who are overweight or obese may be referred to specialists that can help them get or keep their weight under control before or during pregnancy. […] Watching Weight Gain: Although this may be difficult during pregnancy, gaining between 25 to 35 pounds only, the ideal weight gain during pregnancy, is recommended by most doctors. It’s important to note, however, that this is just a general guideline. It doesn’t always apply to everyone. A physician should work closely with you in order to find the ideal weight gain for your pregnancy and work to prevent excessive weight gain.

    Fetal macrosomia is unforeseeable and isnt diagnosed until after the baby is born. Since a babys weight cant be accurately predicted during pregnancy, its difficult to predict if your baby will have fetal macrosomia. […] A healthy weight can prevent fetal macrosomia. Managing your diet and weight gain before and during pregnancy will help minimize the risk of fetal macrosomia. If youre considering getting pregnant and youre obese, youll likely be referred to a professional who can help get you to a healthy weight for pregnancy. […] Managing your diabetes minimizes the risk of fetal macrosomia. If you have untreated diabetes, gestational or pregestational, the risk of your baby having fetal macrosomia increases.

    Maternal factors such as excess pre-pregnancy weight, excessive weight gain, and diabetes during pregnancy increase the likelihood of macrosomia in the newborn. […] Excess weight changes the intrauterine environment and leads to a higher risk of obstetric and neonatal complications. […] This study indicates that pre-pregnancy excess weight and excessive weight gain have a marked effect on the onset of macrosomia, which is independent of other variables. […] To restrain the spread of epidemic excess weight, women must receive a comprehensive intervention before, during, and after pregnancy.

    LGA and fetal macrosomia associated with poor glycemic control can be prevented by effective blood glucose management below a mean blood glucose level of 100 mg/dl before and during pregnancy; additionally, closely monitoring weight gain and diet during pregnancy can help to prevent LGA and fetal macrosomia. […] Women with obesity that undergo weight loss can greatly decrease their chances of having a macrosomic or LGA infant. […] Additionally, regular prenatal care and routine check-ups with one’s physician are important in planning pregnancy, especially if one has obesity, diabetes, hypertension, or other conditions before conception. […] Management of gestational diabetes through dietary modifications and anti-diabetic medications has been shown to decrease the incidence of LGA. […] The use of metformin to control maternal blood glucose levels has shown to be more effective than using insulin alone in reducing the likelihood of fetal macrosomia.

    In the past, about 60% of babies born to diabetic mothers were above the 95th percentile of the same age group in body weight, but this has recently decreased to 20-30%, due to improvements in gestational diabetes treatment. […] Considering these, prenatal treatment, such as GDM control and maternal weight control, is the most important factor in growth outcomes. […] Preventing in-utero over-nutrition by avoiding maternal overweight and/or controlling gestational diabetes will help to avoid overweight in the newborn and during childhood. […] Careful monitoring and proper strategies for prenatal care, and postnatal feeding and physical activity for catch-down growth may be helpful to prevent later adverse results.

    https://www.mdpi.com/2077-0383/12/11/3852
    Gestational diabetes mellitus (GDM) is associated with serious maternal and fetal complications, in particular, fetal macrosomia and large for gestational age (LGA), which predisposes to a higher risk of childhood obesity and type 2 diabetes mellitus later in life. […] Early prediction and diagnosis of GDM leads to early interventions such as diet and lifestyle, which could mitigate the maternal and fetal complications associated with GDM. […] Thus, we hypothesise that the HbA1c level at around 24 to 28 weeks may predict the development of fetal macrosomia or an LGA baby in women with GDM, which could be useful for better prevention of fetal macrosomia and LGA. […] Early diagnosis of fetal macrosomia could help optimise the delivery time and reduce the risk of adverse outcomes. […] Therefore, it is essential to identify potential indicators for fetal macrosomia and LGA babies.

    Objective To determine if a low glycaemic index diet in pregnancy could reduce the incidence of macrosomia in an at risk group. […] Conclusion A low glycaemic index diet in pregnancy did not reduce the incidence of large for gestational age infants in a group at risk of fetal macrosomia. It did, however, have a significant positive effect on gestational weight gain and maternal glucose intolerance. […] We have found that a low glycaemic index diet in pregnancy had no effect on infants birth weight in a group at risk of fetal macrosomia. It did, however, have a significant positive effect on gestational weight gain and on maternal glucose intolerance. […] Importantly, we identified no adverse outcomes associated with the use of a low glycaemic index diet in pregnancy. Potential benefits were seen, particularly in terms of limiting maternal gestational weight gain to within Institute of Medicine guidelines and an improvement in maternal glucose homoeostasis. These findings were identified after a single formal small group dietetic session in early pregnancy. This suggests that this type of simple dietary intervention is adequate in improving maternal nutrition.

    A diet with a low glycemic index has no effect on the incidence of macrosomia in an at-risk group, but a positive effect on maternal outcomes. […] A low glycemic index diet in pregnancy did not reduce the number of large for gestational age infants in a group at risk for fetal macrosomia. […] Gestational weight gain and the incidence of impaired glucose tolerance were significantly less for pregnant women on a low glycemic index diet. […] The use of a low glycemic index diet in pregnancy is a simple, safe, and effective measure to improve maternal glucose homeostasis and to reduce gestational weight gain, conclude the study authors.

    Exercise may be a useful method to control weight gain during pregnancy. […] A randomized controlled study revealed that pregnant women who did not exercise were 2.5 times more likely to give birth to newborns with macrosomia. […] A systematic review and meta-analysis showed that exercise during pregnancy could decrease the incidence of macrosomia without affecting the likelihood of having an infant with preterm birth or low birth weight. […] Our study also revealed that individualized exercise guidance could effectively reduce GWG regardless of prepregnancy BMI. […] More importantly, we found that exercise during pregnancy reduces the occurrence of macrosomia by decreasing GWG; that is, GWG mediates the effect of exercise on macrosomia. […] Our study showed that exercise during pregnancy is a protective factor against macrosomia, large for gestational age infants, and excessive gestational weight gain. […] It is also recommended that all pregnant women without contraindications perform physical activity during pregnancy according to their own conditions with management and supervision aided by information technology devices.

    Control Diabetes: Controlling blood sugar during pregnancy is one of the best ways to help prevent fetal macrosomia. Make sure your doctor does a gestational diabetes test during pregnancy. […] Keep All Prenatal Appointments: Prenatal check-ups are crucial during pregnancy as it allows doctors to examine the pregnancy and run tests to ensure everything is normal. Prenatal appointments measure fetal growth and overall fetal health. It also helps them prepare for your upcoming birth and the steps needed should you show signs of carrying a large infant. […] Stay Active: As much as you are able to healthily, stay active during your pregnancy. Unless you are restricted to bed rest, a healthy level of activity can help manage weight gain and prepare your body for labor and delivery. Your doctor can advise you on what is a healthy level of activity based on your overall health.

    Fetal macrosomia is associated with significant maternal and neonatal morbidity. […] Preventing the vicious cycle effect of fetal macrosomia and childhood obesity is an increasingly pertinent issue. […] Prevention of fetal macrosomia is entirely dependent upon correct identification of those at risk. Maternal weight, gestational weight gain and glycaemic control are the risk factors for fetal macrosomia that are most amenable to intervention, and have potential maternal health benefits beyond pregnancy and childbirth. […] In this review we outline the contemporary evidence for the prediction and prevention of fetal macrosomia, which is indeed a contemporary dilemma.

    A new study published in the Journal Reproductive and Developmental Medicine (RDM) has found a strong association between fetal macrosomia (high birth weight) and overweight and obesity in early childhood among the U.S.-born children aged 2-6 years. […] The researchers suggested fetal macrosomia may be a marker of intrauterine overnutrition and metabolic dysregulation, which may predispose children to excess weight gain and obesity later in life. They recommended that prenatal care providers should monitor fetal growth and counsel pregnant women about the potential risks and complications of having a large baby, as well as the importance of healthy lifestyle behaviors for themselves and their children. […] Preventing in-utero over-nutrition and weight gain during pregnancy could be a promising strategy to break the vicious transgenerational cycle of obesity crisis and mitigate the risks towards the subsequent generations, particularly among the population of colors.
