Association between migraine and exclusive breastfeeding: A cross-sectional study
Abstract
BACKGROUND: Medical conditions may preclude a mother from exclusively breastfeeding her infant; however, the association between migraine and the duration of exclusive breastfeeding is not well known.
OBJECTIVE: To evaluate the association between migraine and the duration of exclusive breastfeeding in a representative sample of Canadian females.
METHODS: We used the Canadian Community Health Survey, a cross-sectional survey, to identify females aged 20-49 years who delivered a baby in the previous 5 years. History of migraine was self-reported. Females reported if they breastfed their baby, and among those who did, they further reported the duration of exclusive breastfeeding. We evaluated the association between migraine and the rate of breastfeeding, and the duration of exclusive breastfeeding adjusting for selected covariates.
RESULTS: We included 5282 females, of whom 862 (16.3%) had migraine. Compared to females without migraine, females with migraine were less likely to have high income (annual income >$80,000: 362 [42.0] vs. 2276 [51.6]), and more likely to have comorbid mood (176 [20.5] vs. 378 [8.6%]) and anxiety (196 [22.8%] vs. 406 [9.2%]) disorders. Migraine was not associated with breastfeeding (proportion of females who did not breastfeed, migraine vs. no migraine: 114/862 [13.2%] vs. 498/4420 [11.3%]; adjusted odds ratio 1.03; 0.74-1.27); however, females with migraine had lower odds (≥6 months of exclusive breastfeeding: 216/688 [31.4%] vs. 1325/3561…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
