Home / Glossary Small for gestational age (SGA) By Motherly Editors April 3, 2024 Rectangle Definition Small for Gestational Age (SGA) refers to newborn babies who are less in size or weight than is normal for a specific gestational age. It typically applies to infants whose weight is below the 10th percentile for their gestational age. This condition may be due to various reasons, including genetic factors, maternal health issues or inadequate nutrition during pregnancy. Key Takeaways Small for Gestational Age (SGA) refers to a baby that is smaller than the usual average size, as per the number of weeks of pregnancy. An SGA baby may have a birth weight below the 10th percentile for babies of the same gestational age. SGA can be a result of a variety of reasons, such as maternal lifestyle factors, complications during pregnancy, or genetic factors. It can potentially lead to certain health problems for the baby, both in the short term and later in life. Not all babies who are small are SGA babies. Some are just naturally smaller. However, if a baby is diagnosed as SGA, it is important to monitor their growth and development closely, both during pregnancy and after birth, to ensure that they are growing at a healthy rate. Importance The term Small for Gestational Age (SGA) is crucial in maternal and child health because it refers to infants who are born with a weight below the tenth percentile for their gestational age. This term is important as it can indicate potential health risks and complications, such as perinatal asphyxia and hypothermia, and it is associated with a higher likelihood of developmental delays, learning difficulties, and chronic diseases later in life. Detecting SGA in an infant can enable healthcare providers to carry out necessary interventions and close monitoring to ensure the baby’s growth and development. This can help improve the child’s long-term health and wellbeing. Explanation Small for gestational age (SGA) is a term that is primarily used to describe a fetus or newborn that is smaller in size than is expected for the baby’s gestational age. Its primary purpose is to help healthcare professionals track and monitor the growth and development of a baby during pregnancy and after birth. By using this term, doctors can identify babies who might be at a higher risk of certain health problems, including low birth weight, difficulty managing blood sugar levels, lower resistance to infection, and increased risk of neonatal mortality. SGA is a crucial tool that aids in enabling specialized care and immediate medical attention that may be required for the baby. It allows doctors to intervene, if necessary, to ensure the baby’s health and development both in utero and after birth. For instance, if a baby is identified as SGA, it could indicate inadequate nutrient or oxygen supply, which would necessitate specific care strategies or the need for an early delivery. Therefore, assessing whether a newborn is SGA forms an integral part of neonatal and perinatal medicine to ensure the best possible outcome for the baby’s health. Examples of Small for gestational age (SGA) Example 1: A mother gives birth at 38 weeks, but her baby only weighs 5 pounds, which is less than the 10th percentile for that particular gestational age. Despite being carried to near full term, the baby’s weight indicates that it is SGA, possibly due to factors such as maternal malnutrition, smoking during pregnancy, or complications in placental development. Example 2: In a rural area with insufficient healthcare facilities, a mother gives birth to twins at 37 weeks. Both babies weigh significantly less than what is average for this gestational age. The babies are identified as SGA, mostly attributed to inadequate prenatal care, maternal stress, and a multiple pregnancy where the mother’s nutrition demands might have been higher. Example 3: A mother with a history of high blood pressure gives birth at 40 weeks gestational age. Her newborn weighs only 5 pounds, which is lower than should be expected at full term. The baby is classified as SGA, possibly due to maternal hypertension, which can impact the growth of the fetus.

These include problems with the placenta, health issues in the mother such as high blood pressure or heart disease, infections, smoking or alcohol use during pregnancy, and malnutrition. What are the risks associated with being Small for Gestational Age (SGA)? Babies who are SGA may have problems such as difficulty fighting off infections, trouble maintaining body temperature, low blood sugar, and a higher risk of developing learning disabilities. However, with the right care, many SGA babies grow up healthy. How is Small for Gestational Age (SGA) diagnosed? SGA is typically diagnosed at birth when the baby’s weight and measurements are compared to averages for their gestational age. Sometimes, it can be detected during pregnancy through prenatal ultrasounds. What is the treatment for Small for Gestational Age (SGA) babies? Treatments for SGA babies depend on the baby’s overall health and the underlying reasons for their small size.
