Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2017 Objective: To explore whether there is an association between socioeconomic status and maternal body mass index, and duration of partial breastfeeding/exclusive breastfeeding of Norwegian infants in 2016. Design: Cross-sectional design. Baseline data from a randomized controlled trial, collected by a Food Frequency Questionnaire. Setting: Recruitment was done through Facebook and child health care centres in 2016. In total 1048 infants/parents were interested in participating in the study Early Food for Future Health. Subjects: A total of 715 infant/mother- dyads completed the questionnaire when the child was between 5 and 6 months old. Results: At 5 months of age 16.4 % of the infants were exclusively breastfed. Infants of mothers with overweight/obesity had reduced odds of being exclusive breastfed the first 4 months of age and lower odds of being partially breastfed at 3 and 4 months, compared to infants of mothers with normal body mass index. Infants of highly educated mothers had higher odds of being partially breastfed at 1, 2 and 5 months, compared to infants of mothers with less education. Infants of multiparous mothers had higher odds of being exclusively breastfed the first 5 months of age, compared to infants of mothers with one child. Conclusions: Our results show that duration of breastfeeding varies with socioeconomic status and maternal body mass index in Norway. Targeting groups with low socioeconomic status, and mothers with overweight/obesity is important as they are less likely to breastfeed within the recommendations.
