Understanding Preterm Labor: Causes and the Rising Global Trend

Preterm labor, defined as the onset of labor before 37 weeks of gestation, is a growing concern worldwide. Each year, approximately 15 million babies are born prematurely, accounting for about 1 in 10 births globally (WHO). The rates of preterm birth have been steadily rising in many regions, leading to increased risks of neonatal complications, long-term health challenges, and emotional strain on families.

Understanding the causes behind preterm labor and why it is increasing globally is crucial in developing better prevention strategies and improving care for at-risk pregnancies.

Common Causes of Preterm Labor

Preterm labor is often unpredictable, but several factors can increase the likelihood of early delivery:

1. Infections & Inflammation

Maternal infections—especially urinary tract infections (UTIs), bacterial vaginosis, and intrauterine infections—can trigger an inflammatory response that leads to early contractions. Chronic inflammation in the placenta is also linked to preterm labor.

2. Multiple Pregnancies (Twins, Triplets, or More)

Carrying multiple babies increases the likelihood of preterm labor due to uterine overdistension and increased strain on the cervix.

3. Maternal Health Conditions

Pregnant individuals with high blood pressure (preeclampsia), diabetes, heart disease, or kidney disorders are at greater risk of delivering prematurely.

4. Uterine & Cervical Issues

An incompetent cervix, uterine abnormalities, or a history of preterm birth can contribute to an early delivery.

5. Lifestyle & Environmental Factors

Smoking, alcohol use, drug use, and high stress levels have all been linked to increased rates of preterm labor. Studies have also suggested that exposure to air pollution and environmental toxins can negatively impact pregnancy outcomes.

6. Advanced Maternal Age & Assisted Reproductive Technology (ART)

Women conceiving later in life or through IVF treatments face an increased risk of preterm labor due to hormonal changes and a higher likelihood of carrying multiples.

The Rising Global Trend in Preterm Birth

Despite advancements in prenatal care, preterm birth rates are climbing in many countries. The reasons for this increase vary by region but include:

1. Increasing Maternal Age

More women are having babies later in life, which is associated with higher risks of pregnancy complications, including preterm birth (CDC).

2. Higher Rates of Chronic Conditions

Global rates of obesity, hypertension, and diabetes are rising, contributing to pregnancy complications that can lead to preterm birth.

3. Rising Use of Assisted Reproductive Technologies (ART)

With IVF and fertility treatments becoming more common, multiple pregnancies and preterm labor rates have increased as a result.

4. Socioeconomic & Healthcare Disparities

In low-income countries, preterm birth rates are often higher due to limited access to quality prenatal care, nutrition, and medical interventions.

5. Environmental & Pollution-Related Factors

A 2024 study found microplastics in placental tissues, raising concerns about environmental pollutants contributing to preterm births (The Guardian).

How Can We Reduce Preterm Births?

Tackling the growing crisis of preterm birth requires a global effort that includes:

✔ Expanding Access to Prenatal Care – Early screening and treatment for infections, high blood pressure, and diabetes can lower risks.

✔ Improving Maternal Nutrition – Better access to prenatal vitamins, iron, and folic acid supplements can support healthy pregnancies.

✔ Reducing Environmental Risks – Addressing air pollution and exposure to harmful chemicals may help lower preterm birth rates.

✔ Supporting Research & Awareness – Increased funding for preterm birth research, public education, and policy changes can drive long-term improvements.

✔ Employer & Workplace Support – Companies can help reduce stress-related preterm labor by offering better parental leave, workplace accommodations, and maternal health support.
