Babies are less likely to develop a respiratory or gastrointestinal infection if they are exclusively breastfed for at least 6 months, according to a Dutch study, supported by the World Health Organization (WHO), in the journal Pediatrics. The study supports the current recommendation that infants be breastfed exclusively for 6 months and support “current health-policy strategies that promote exclusive breastfeeding for 6 months in industrialized countries,” the researchers conclude.
The American Academy of Pediatrics believes that breastfeeding is the optimal source of nutrition through the first year of life. The AAP recommends exclusively breastfeeding for a minimum of four months but preferably for six months, and then gradually adding solid foods while continuing breastfeeding until at least the baby’s first birthday. Thereafter, breastfeeding can be continued for as long as both mother and baby desire it.
Breastfeeding should begin as soon as possible after birth, usually within the first hour. Newborns should be nursed whenever they show signs of hunger — approximately eight to twelve times every twenty-four hours. The amount of time for each feeding varies widely for each mother-baby pair: It may be anywhere from ten to forty-five minutes in the first few weeks.
Here’s a detailed report on the study from Reuters Health: Dr. Henriëtte A. Moll and colleagues at the Erasmus Medical Center in Rotterdam analyzed health data on roughly 4,100 infants born in Rotterdam between 2002 and 2006.
They looked at whether the babies were breast fed, and until what age; whether they were given other foods and at what age, and whether they were treated for any common infections such as serious colds, ear or throat infections, pneumonia, bronchitis, or stomach flu.
In the first 6 months of life, nearly half of all the infants had a respiratory tract infection and nearly 8 percent had a gastrointestinal infection. Between 7 months and a year, 37 percent of the infants had a respiratory tract infection and 9 percent had a stomach bug.
“We observed protective effects of breastfeeding on infectious diseases mainly in the first 6 months of life,” the researchers report. “Exclusive breastfeeding until age 6 months tended to be more protective, than exclusive breastfeeding until age 4 months.”
In the first 6 months, exclusive breastfeeding cut the risk of respiratory tract infections by about two-thirds, while exclusive breastfeeding for 4 months cut the risk by one third to a half. The reduction in risk from exclusive breastfeeding for 6 months was less pronounced in the second half of the first year of life.
Exclusive breastfeeding — whether 4 or 6 months — appeared to have a less dramatic effect in reducing the risk of developing gastrointestinal infections, especially in the second half of the first year.
The study pulled data from a large population of children that allowed the researchers to adjust for factors that could have an impact on infection rates such as family history of asthma, mite allergies, and smoking in the household.
Breastfeeding rates have been trending upward since 1993 in the United States, with the steepest jump seen most recently among African American women. According to the Centers for Disease Control and Prevention, 77 percent of infants born between 2005 and 2006 were breastfed at some point compared to 60 percent in 1993.
The largest drop-off in breastfeeding occurs when women return to work, a fact Moll believes must be addressed by “translating the study results into practice.”
She favors extending maternity leave to 4 to 6 months after the birth of a child and creating for working women “adequate facilities to continue breastfeeding.” Failing that, breast pumps can be used to express mother’s milk for use later.
A recent study found that $13 billion could be saved annually if 90 percent of U.S. mothers would exclusively breastfeed for 6 months. The findings were disputed by the infant formula industry group, International Formula Council, which said the researchers failed the account for the many costs of breastfeeding such as training mothers, time off from the job and setting aside space at the worksite.
Not so, says Dr. Ruth Lawrence, chair of American Academy of Pediatrics’ Section on Breastfeeding.
“From a practical standpoint, it’s to an employer’s benefit to facilitate breastfeeding,” she told Reuters Health, adding that the study by Moss and colleagues adds to research that shows that breastfed babies are healthier babies.
“Absenteeism of parents of bottle-fed babies is extremely high and that’s costly to an industry and it’s a lot cheaper to facilitate breastfeeding,” Lawrence said.he Centers for Disease Control and Prevention, 77 percent of infants born between 2005 and 2006 were breastfed at some point compared to 60 percent in 1993.
