Introduction
Definition of high birth weight
Newborns weighing greater than four thousand grams (approximately 8 pounds and thirteen ounces) are considered to have an excessive birth weight. On the other hand, low birth weight newborn weight is much less than five kilos and eight ounces (2,500 grams).1
Importance of birth weight in infant health
Birth weight is an essential indicator of an infant’s growth and health because it can help determine the probability of death or disability among newborns; besides, various studies have shown that both extremes may lead to negative outcomes. For example, those children who are born heavy have higher chances of suffering from such complications as respiratory distress syndrome, birth trauma or even long-term health issues like childhood obesity. Proper prenatal care is needed to identify at-risk pregnancies and manage them accordingly. t.
The purpose of exploring factors contributing to high birth weight
It is important to know what factors contribute towards high birth weight since this knowledge has many benefits. The first is doctors will be able to identify pregnancies that are likely to result in adverse events hence taking appropriate measures early enough so as to minimize risks. Additionally, investigating these determinants enhances our understanding of the health of babies during pregnancy thereby guiding public interventions. This is aimed at improving the well-being of mothers and their babies.
Ultimately research in this field seeks to improve the health of mothers and their babies by identifying the intricate interactions between maternal, genetic, environmental, lifestyle, and medical factors.3,4
Maternal factors
Maternal weight and body mass index(BMI)
- The mother's obesity's effect on birth weight: Maternal obesity is related to high birth weight and, therefore, the increased chances of problems during pregnancy or delivery. According to investigations, when a woman is overweight, the baby tends to develop the condition called macrosomia to metabolic disturbances and birth injury.5
- Maternal underweight and high birth weight
Genetic factors
Genetic influence on birth weight: The amount you weigh at birth is mostly controlled by the genes you acquire from your parents. If your parents are overweight, you are more likely to be heavier as well.11
Birth weight and inherited traits: Certain traits that run in families can cause babies to be larger at birth. It's similar to passing on characteristics like hair texture or eye colour, except, in this instance, the trait at hand is your birth weight.12
Ethnicity and race: Each ethnic group has a different average birth weight. Along with where they live and what they consume, their genetic composition also plays a role in this. There are genetic factors that influence a baby's birth weight and are more prevalent in particular ethnic groups.13
Environmental factors
Socioeconomic status
Impact of Socioeconomic Factors on Birth Weight: An individual's start weight is extensively inspired with the aid of their socioeconomic status, which encompasses factors like profits, schooling, and career. born to moms from lower socioeconomic backgrounds normally weigh less than the ones born to mothers from higher socioeconomic backgrounds.14
Lifestyle factors
Substance use
- Smoking's Effects on Birth Weight: Smoking during pregnancy has been strongly associated with unfavourable birth outcomes, such as low birth weight. Nicotine and other harmful chemicals in cigarettes restrict the foetus's blood flow, reducing the amount of oxygen and nutrients it receives and requires for healthy development18
- Effect of Alcohol Use on Foetal Development: Drinking alcohol while pregnant can have unfavourable effects on the improvement of the foetus. Foetal alcohol spectrum issues (FASDs) may also end result from it, displaying impairments in cognition, behaviour, and physical functioning. Alcohol can have an effect on a fetus's ability to expand typically and move the placenta, which could bring about low beginning weight and increase limitations18
Physical activity
- Maternal Exercise and Birth Weight: Physical pastime on a normal basis for the duration of pregnancy is typically wholesome and may assist acquire the proper delivery weight. Moderate exercise can decorate placental blood go with the flow and the cardiovascular health of the mother, both of which can advantage foetal increase. Nonetheless, it's far best to avoid excessive or strenuous exercise as it can have a bad effect on beginning weight19
- Recommendations for Safe Exercise While Expecting: It is recommended that pregnant women carry out mild-intensity cardio exercising for no less than a hundred and fifty minutes per week, dispensed during the week. In well-known, secure activities include swimming, on foot, and desk-bound biking. But before beginning or maintaining an exercise programme while pregnant, it's imperative to speak with a healthcare professional, particularly if there are underlying health concerns20
Medical factors
Diabetes
Impact of Gestational Diabetes on Foetal Growth: Macrosomia results from diabetes due to the increased transfer of glucose to the baby an excessive amount of glucose passes via the placenta, and the foetus produces more insulin, resulting in fat deposition and a faster increase in weight.21
It is essential to regulate blood glucose in pregnancy via food plan, exercise, and, if important, insulin therapy. Regular blood glucose monitoring, a diabetic-friendly diet, maintaining a healthy weight, and engaging in mild physical exercise are all essential components of gestational diabetes control. If lifestyle adjustments are made and blood glucose tiers stay high, insulin therapy can be initiated.22
Conclusion
Various maternal factors associated with high birth weight include parity, age, height, pre-pregnancy weight and pregnancy weight. Weight gain during pregnancy, Diabetes, family income level, and previous history of macrosomia were also found to be significantly associated with high birth weight in previous studies.
FAQs
Q: What is a high birth weight?
A: Generally speaking, a baby is deemed to have high birth weight if their weight is greater than 4,000 grammes, or roughly 8 pounds, 13 ounces.
Q: Are there any aspects of lifestyle that have an impact on birth weight?
A: Indeed, birth weight can be impacted by specific lifestyle factors. For instance, smoking by the mother during pregnancy is linked to lower birth weights, but excessive weight gain by the mother during pregnancy can result in higher birth weights.
Q: Is a high birth weight usually a reason for alarm?
A: Not always. While a mother's or baby's high birth weight may occasionally be a sign of underlying health problems, many higher-weight babies are healthy and do not face complications. Healthcare professionals, however, might keep a closer eye on these infants in case of any complications, like shoulder dystocia during delivery or a higher chance of childhood obesity.
Q: Is it possible to control or manage birth weight?
A: Although some factors, like genetics, cannot be changed, living a healthy lifestyle, taking care of maternal health conditions like diabetes, and getting the right prenatal care can all help to improve the outcome of birth weight. Seeking advice from a healthcare professional is crucial for tailored guidance throughout pregnancy.
