Prenatal and Maternal Health
Nearly one in four (23.4 percent) women are obese before becoming pregnant — which can increase the risk for a wide range of health complications for the baby and the mother.1 More than 6 percent (approximately one in 16) of pregnant women have or develop diabetes during pregnancy — known as gestational diabetes.2
The rate of women who were obese before becoming pregnant and participating in the WIC program has dramatically increased over the past 20 years, increasing 86 percent from 19.2 percent in 1994 to almost 36 percent in 2014.3,4 In 1994, the rates ranged from a low of 1 percent in Iowa to a high of 24.7 percent in Vermont.
By 2004, 28.8 percent of women who were enrolled in the WIC program were obese prior to becoming pregnant.5 Rates ranged from a low of 21.1 percent in Rhode Island to a high of 34.3 in Alabama. Nineteen states and Washington D.C. had more than a 20 percent increase of women being obese, with five states having more than a 45 percent increase. [19 states out of 31 and Washington, D.C. reported data in 1994 and 2004.]
And by 2014, the percent of women who were obese doubled in 13 states and Washington, D.C.6 Iowa had the greatest increase from 1 percent in 1994 to 40.8 percent in 2014, followed by Illinois, which increased by more than seven times, from 5 percent in 1994 to 35.9 percent in 2014. [19 states out of 44 and Washington D.C. reported data in 1994 and 2014.]
Women Enrolled in WIC and Were Obese Prepregnancy - 1994, 2004 and 2014
Maternal health — including obesity, poor nutrition and type 2 diabetes — can increase risk for miscarriages, birth defects, slow fetal growth, prematurity and low birth weight babies. Poor maternal nutrition can also lead to increased risk for abnormal brain development, developmental delays, diabetes, hypertension, heart disease, obesity and lower IQ in babies.7,8
- One in nine children in the United States is born prematurely (before 37 weeks of gestation or 3 weeks early). Premature births cost the country $26.2 billion annually, or $51,600 per baby, in direct medical and lifetime added costs.9,10
- On average, there were approximately 23,400 infant deaths per year in the United States over the past decade.11 The U.S. infant mortality rate (6.0 per 1,000 live births, 2013) is almost twice as high as some comparable countries — the average infant mortality in comparable countries is 3.5 per 1,000 live births.12 The United States ranks 24th among developed countries.13
Good prenatal healthcare is important to help reduce risks and complications. Many experts, however, now believe that much of prenatal care, which usually begins during the first three months of pregnancy, comes too late to prevent many serious maternal and childhood health problems. Even the first few weeks after conception are critical for healthy fetal development. Medical professionals recommend an increased focus on regular well-care and preventive healthcare for women throughout childbearing age, including screening for risk of obesity and related chronic health conditions.
The American Academy of Pediatrics (AAP) recommends breastfeeding as a natural source of nutrition that ?provides the healthiest start for an infant.? The NAM and AAP recommend that babies be breastfed exclusively for about the first 6 months and should continue breastfeeding through the first year of life.14,15,16
Only around half (51.8 percent) of infants are breastfeeding at 6 months — with rates of exclusive breastfeeding rates ranging from 9.3 percent in Mississippi to 33.8 percent in Montana.17
Health Benefits of Breastfeeding
There are mixed findings on the potential relationship between breastfeeding and obesity among infants.18,19,20 However, there are a number of identi ed health bene ts for breastmilk as the ?first food.? In addition, there are weight-related bene ts that have been identi ed for mothers who breastfeed.21,22 Women who exclusively breastfeed for at least three months loose up to 3.2 pounds more compared to women who do not breastfeed or breastfeed non exclusively one-year postpartum, and are more likely to return to the same or lower BMI as prepregnancy.23
- Infants: Lower risk of ear and gastrointestinal infections, necrotizing enterocolitis (a gastrointestinal disease), diabetes and obesity.25 Some research suggests it may also reduce risk for asthma and allergies, childhood leukemia and sudden infant death syndrome (SIDS).25,26,27,29 Some research has found children who are breastfed longer are more likely to have better developed language skills, verbal and nonverbal intelligence during childhood, greater upward social mobility, higher neurological development and lower stress markers.29,30
- Mothers: Lower risk of breast and ovarian cancer, type 2 diabetes and postpartum depression. It has been shown to help mothers bond with the child and mothers who nurse miss less work.31,32
- Economic: Families can save on cost of formula. In addition, around $2.2 billion could be saved in annual medical costs if breastfeeding recommendations were met.33
