Importance Major congenital abnormalities, or birth defects, carry significant medical, surgical, cosmetic, or lifestyle consequences. Such abnormalities may be syndromic, involving multiple organ systems, or can be isolated. Overall, 2% to 4% of live births involve congenital abnormalities. Risk factors for birth defects are categorized as modifiable and nonmodifiable. Modifiable risk factors require thorough patient education/counseling. The strongest risk factors, such as age, family history… 

Maternal alcohol consumption and risk of offspring with congenital malformation: the Japan Environment and Children’s Study

Maternal low-to-moderate alcohol consumption during pregnancy, even in early pregnancy, displayed no significant adverse impact on congenital heart defects, male genital abnormalities, limb defects, orofacial clefts, severe brain abnormalities, or gastrointestinal obstructions.

Prevalence and factors associated with congenital malformations in live births

The variables pointed out in the study integrated a predictive model that can help in the planning of health services, suggest hypotheses regarding etiological factors, and form prenatal care actions with attention to the identifi ed factors.

Bariatric surgery and the risk of congenital anomalies in subsequent pregnancies.

Having bariatric surgery was a risk factor for birth defects, and particularly heart and musculoskeletal defects, after fortification, however, an association was no longer present.

Prevention and awareness of birth defects across the lifespan using examples from congenital heart defects and spina bifida

The clinical and public health communities have begun to expand their mission and activities to include a focus not only on surveillance during pregnancy/infancy and primary prevention opportunities, but also on the needs of children, adolescents and adults and secondary prevention that can support the health and well-being of individuals living with birth defects across the lifespan.

Bariatric surgery and birth defects: A systematic literature review

Study of the association between bariatric surgery and birth defects vary with respect to the surgical procedures included, birth defects ascertainment methods and approaches used to account for maternal BMI, so it is not possible to draw a conclusion.

Inflammatory bowel disease and risk of birth defects in offspring.

Findings suggest that inflammatory bowel disease is associated with the risk of abdominal wall and central nervous system defects, and that introduction of immunobiologic medications is unlikely to be associated with added risk.

Diabetes during Pregnancy: A Maternal Disease Complicating the Course of Pregnancy with Long-Term Deleterious Effects on the Offspring. A Clinical Review

Both PGDM and GDM may cause various motor and behavioral neurodevelopmental problems, including an increased incidence of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD).

Risk Assessment for Birth Defects in Offspring of Chinese Pregnant Women

A nomogram risk model for any type of birth defect in a Chinese population based on important modifying factors in pregnant women is developed and could be a tool for clinicians to assess the risk of birth defects and promote health education.
