What Are Ovarian Cysts Signal? Understanding Their Implications by Dr. Pankaj Lodha, best gynecologist in Mumbai, India

Understanding the Risks and Causes of Prematurity

Premature birth, which occurs when a baby is born before 37 weeks of gestation, is a major global health issue. It is estimated that approximately 15 million babies are born prematurely each year, and complications associated with preterm birth are the leading cause of death in children under five.

Understanding Prematurity Risks: Awareness gets better outcomes

What is Prematurity?

A full-term pregnancy typically lasts 40 weeks. Prematurity occurs when a baby is born too early, often before their organs, especially the lungs and brain, fully develop. Depending on how early the baby is born, prematurity is categorized as:

  • Late Preterm: 34-36 weeks
  • Moderately Preterm: 32-34 weeks
  • Very Preterm: Less than 32 weeks
  • Extremely Preterm: Less than 28 weeks

The earlier a baby is born, the higher the risk of health complications, including breathing difficulties, feeding problems, and developmental delays.

Key Causes of Prematurity

Premature birth can occur for various reasons, many of which are beyond the control of expectant mothers. Common causes include:

1. Medical Conditions of the Mother: 

  • Infections: Urinary tract infections, sexually transmitted infections, and untreated maternal infections can trigger preterm labor.
  • Preeclampsia: High blood pressure and damage to other organs, such as the liver or kidneys, can necessitate early delivery.
  • Gestational Diabetes: Complications associated with uncontrolled gestational diabetes may lead to preterm birth.

2. Multiple Pregnancies:

Women carrying twins, triplets, or more are at a higher risk of premature delivery due to the increased strain on the uterus.

3. Short Interval Between Pregnancies:

Conceiving within six months of a previous birth significantly increases the likelihood of a premature delivery.

4. Lifestyle Factors:

  • Smoking, alcohol use, and illicit drug use during pregnancy can lead to complications, including prematurity.
  • Poor nutrition or being underweight/overweight before conception may also contribute to early delivery.

5. Uterine and Cervical Issues:

Weak cervical tissue or structural abnormalities in the uterus can make it difficult to carry a pregnancy to term.

6. Stress and Trauma:

Chronic stress, physical trauma, or psychological conditions such as depression and anxiety can increase the risk of preterm labor.

    Risk Factors for Premature Birth

    In addition to the direct causes, certain factors may increase a woman’s likelihood of having a premature baby:

    • History of Preterm Birth: Women who have delivered prematurely before are at greater risk.
    • Maternal Age: Women under 17 or over 35 are more likely to deliver early.
    • Low Socioeconomic Status: Limited access to prenatal care, poor living conditions, and high levels of stress can all contribute to preterm birth.
    • Ethnicity: Studies have shown that African-American women are at a higher risk for preterm births, although the reasons remain complex and multifaceted.

    ​Complications Associated with Prematurity

    Premature babies often face challenges, including:

    • Respiratory distress syndrome (RDS) due to underdeveloped lungs.
    • Infections due to their immune systems being underdeveloped.
    • Feeding difficulties and growth issues.
    • Long-term complications include vision problems, hearing loss, and cognitive delays.

    Preventive Measures and Awareness

    While not all preterm births can be prevented, there are steps expectant mothers and healthcare providers can take to reduce the risks:

    • Early and Regular Prenatal Care: Timely monitoring can identify and manage potential complications early.
    • Healthy Lifestyle Choices: Avoiding smoking, alcohol, and drugs while maintaining a balanced diet and proper weight can help.
    • Managing Chronic Conditions: Women with existing health issues like diabetes or hypertension should work closely with their doctors during pregnancy.
    • Spacing Pregnancies: Allowing adequate time between pregnancies gives the body time to recover.

    The Role of Awareness

    Raising awareness about prematurity and its causes is crucial for reducing stigma and empowering women to seek timely care. Observed on November 17, World Prematurity Day focuses on enhancing global understanding and advocating for improved outcomes for premature babies and their families. Equipping expecting mothers with essential facts about prematurity plays a vital role in fostering awareness and preparedness.

    Aiming for a Healthy Pregnancy by Preventing Prematurity
