Choice To Breastfeed Or Bottle Feed Could Be Influenced By Mom's Personality Traits (STUDY)

Personality traits such as extraversion or being prone to anxiety may influence whether a new mom breastfeeds or chooses formula, a new study in the United Kingdom found.

Breastfeeding boosts a baby's defenses against respiratory infections, allergies, obesity and other diseases. Roughly two-thirds of mothers try to breastfeed in the U.K. and the United States, but many stop in the first few weeks after birth.

Dr. Amy Brown, who studies early nutrition at Swansea University in Wales, surveyed 602 mothers of infants ages 6 to 12 months, to see if personality traits were linked to breastfeeding rates. The women in the study ranged in age from 16 to 45 years old, and spanned a spectrum of income, education and professional achievement levels.

Brown found extraverted, conscientious and emotionally stable mothers were more likely to try breastfeeding. But being agreeable or open to new experiences made no difference, according to the findings published Tuesday (Aug. 6) in the Journal of Advanced Nursing.

Many try, but many quit

More than 80 percent of the women in the study tried to breastfeed, but less than half who tried were still breastfeeding six months later. And women who switched from breast to bottle tended to switch quickly. About 73 percent of the women who stopped breastfeeding did so within two weeks after giving birth.

Women who were conscientious — for example, detailed-oriented and punctual — were likely to start, but also likely to stop breastfeeding.

Mothers who kept breastfeeding during the first six months were more extroverted and less anxious than mothers who always bottle-fed or switched to the bottle. The effect was particularly strong within the first six weeks after birth. [Blossoming Body: 8 Odd Changes That Happen During Pregnancy]

Changing laws or changing minds?

Britain's laws seem to make it a friendly place for extended breastfeeding. Mothers are entitled to a year of leave from work, including 39 weeks of paid leave. The 2010 Equality Act guaranteed a woman's right to breastfeed in public places.

"It's not usually work that stops it," Brown said.

Women in the study who stopped breastfeeding were surveyed about why – if they found it uncomfortable, inconvenient or embarrassing. "The findings show the extraverts think breastfeeding is less difficult. But there's no physical reason why that should be," Brown said.

Brown thinks a combination of personality traits and culture led some moms to switch to formula. Breastfeeding rates plummeted in the U.S. and UK during the 20th Century. By 1971, only 24 percent of U.S. mothers even tried breastfeeding. Public health campaigns helped boost breastfeeding rates, but the UK still lags behind other industrialized countries.

"It's kind of a formula-feeding culture in that everyone knows someone who was formula-fed," Brown said. Other family members may want to feed the baby, and older generations who used formula may not understand the new mom's decision. And as news reports of nursing women being kicked out of stores and off trains show, people aren't used to seeing women breastfeed.

Mothers who are extraverted and less anxious may be protected against discouragement, and have the confidence to seek help and overcome struggles with breastfeeding. Meanwhile mothers who were already anxious may worry the baby isn't eating enough, or give in to social pressure, Brown said.

Brown said she hopes the study could help encourage breastfeeding by addressing the need for social support alongside information. Perhaps, along with tips for getting an infant to latch on, a new mom could be given ideas or tools to get through the early weeks of breastfeeding, which can be difficult.

Women need "a list of things they could politely tell their mother-in-law when they tell them to go get the bottle," Brown said.
