BREAST MILK BEST FOR BABIES
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.
These findings, reported in the journal Pediatrics, support the World Health Organization (WHO) 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.
Health data on roughly 4,100 infants born in Rotterdam between 2002 and 2006 was analyzed.
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 50% of all the infants had a respiratory tract infection
- Nearly 8% had a gastrointestinal infection.
- Exclusive breastfeeding for 4 months cut the risk by one third to a half.
- Exclusive breastfeeding cut the risk of respiratory tract infections by about two-thirds
Between 7 months and a year:
- 37% of the infants had a respiratory tract infection
- 9% percent had a stomach bug.
- The reduction in risk from exclusive breastfeeding for 6 months was less pronounced in the second half of the first year of life.
"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."
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% of infants born between 2005 and 2006 were breastfed at some point compared to 60% in 1993.
The largest drop-off in breastfeeding occurs when women return to work, a fact the researchers believe must be addressed by "translating the study results into practice."
They favor 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% 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 employers 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.
