Final answer:
Fetal development may be affected by genetic and environmental factors, with only about 10% of malformations due to environmental causes. Mechanical factors like in utero space limitations and maternal conditions like IUGR also contribute to risks. Preventative measures and awareness of conditions like RDS and SIDS are crucial for infant health.
Step-by-step explanation:
Developmental disorders in fetuses can occur due to a variety of factors. About 6% of all live births present with some form of malformation, most of which are due to genetic reasons. However, as mentioned Environment Health Perspectives (NIH), only about 10% are due to environmental etiologies such as maternal health, infection, and toxicants. Moreover, skeletal and central nervous systems are primarily affected by these complications.
Risk factors for developmental disorders also include mechanical factors that reduce in utero space and movement. Examples of such factors are the first-born status, oligohydramnios, large fetal size, and breech positioning. Additionally, conditions like intrauterine growth restriction (IUGR) can be attributed to maternal, fetal, or placental factors, leading to abnormally slow growth of a fetus.
It's also important to consider risks linked with certain postnatal conditions, such as Sudden Infant Deaesidual Distress Syndrome (RDS) is primarily caused by premature birth, with, gestational diabetes, cesarean delivery, and family history beingth Syndrome (SIDS) where risk factors include low birth weight, pre-term birth, and male sex. Preventative measures like placing an infant on its back to sleep can help reduce these risks. Lastly, R additional risk factors.
