Low Birthweight Babies - What Should You Worry About?
The prevalence of LBW in India is approximately 20%. Males have less frequency of LBW than females. The prevalence is comparatively more in northern India.
Top 10 Alarming Risks of Low Birthweight in Babies1. Preterm Birth: Preterm births are termed so when babies are born before 37 weeks of pregnancy; being born preterm is a major risk factor for LBW babies and is also indirectly responsible for causing neonatal deaths. Preterm labor, which can expel the baby before attaining 37 weeks of pregnancy can cause preterm births.
2. Intrauterine Growth Restriction (IUGR): This is also known as fetal growth restriction or small for gestational age and refers to the retarded growth of the baby during pregnancy, while it is still in the womb. High blood pressure in the mother, placental abnormalities, infections, smoking, alcohol abuse, prescription drug abuse and drug addiction are some of the factors that can cause IUGR. In IUGR, the baby can weigh less than 90% of normal babies of the same gestational age. Fetal ultrasound can help to detect the condition early.
3. Multiple Pregnancies: Based on data from the Centers for Disease Control and Prevention (CDC), multiple pregnancies are a high-risk factor for the premature birth of babies having LBW. Moreover, twin births can result in LBW babies. The chances of an LBW baby also increases if an LBW baby was born in a previous pregnancy.
4. Poor Nutrition During Pregnancy: Improper diet during pregnancy results in poor nutrition. This can drastically reduce the weight of the baby. Controlled trials have shown that improving the motherís food intake during pregnancy effectively reduces LBW in babies. Multivitamin-mineral and especially iron-folate supplementation in conjunction with nutritious food during pregnancy is very effective in reducing the chances of LBW babies.
5. Placental Abnormalities: The placenta grows in the womb and supplies the baby with nutrients and oxygen through the umbilical cord. Abnormalities in the placenta can reduce the flow of blood and nutrients, which can limit the babyís growth. An abnormality called placenta previa, where the placenta is attached to the uterus but blocks the opening of the cervix can lead to a marginally increased risk of LBW babies, but may not be clinically relevant.
7. Chronic Diseases: A pregnant mother who is suffering from chronic diseases like high blood pressure (hypertension), type-2 diabetes mellitus, heart disease, respiratory disease, or kidney damage has a much higher chance of giving birth to an LBW baby.
9. Uterine Fibroids: These are non-cancerous growths in the uterus that can develop in women of childbearing age. Studies have found that interventions for treating fibroids such as uterine artery embolization (UAE) can result in LBW babies.
