WEDNESDAY, June 1, 2022 (HealthDay News) — Longer duration of exclusive breastfeeding may protect against childhood asthma, according to a study published online May 9 in Annals of Allergy, Asthma and Immunology.
Keadrea Wilson, MD, of the University of Tennessee Health Sciences Center at Memphis, and colleagues studied the association between breastfeeding duration and childhood asthma using data from 2,021 mother dyads -child.
The researchers found that among the women, 33% reported breastfeeding from zero to less than two months, 13% two to four months, 9% five to six months, and 45% more than six months. All breastfeeding had a linear protective trend only for asthma. The protective effect was duration-dependent for exclusive breastfeeding and current asthma (odds ratios adjusted [95 percent confidence intervals]0.64 [0.41 to 1.02]0.61 [0.38 to 0.98]and 0.52 [0.31 to 0.87] for two to four months, five to six months and more than six months, respectively). Protective associations with exclusive breastfeeding tended to be stronger in dyads with children born vaginally rather than by caesarean section.
“Our study reinforces current breastfeeding recommendations that reflect recent analysis that shows lower asthma risk with more or less breastfeeding,” Wilson said in a statement.
