Despite the enormous benefits of breastfeeding (BF), its prevalence is suboptimal, with exclusive BF ranging between 7.3 % and 51% in the Saudi community. The aim of this study was to assess the Saudi community's knowledge regarding BF, exposure to BF promotional messages and formula milk advertisements and acceptability of BF in public places. It was a cross-sectional study that included Saudis aged 20-55 years old between December 2019 and June 2020. It utilised a self-administered questionnaire, which asked about background information, knowledge of BF, exposure to BF-promoting messages and exposure to formula milk advertisements and acceptability of BF versus bottle feeding in public. Data were analysed using the Statistical Package for the Social Sciences (SPSS v. 22). For the analysis, a p-value <0.05 was considered significant. The sample included for analysis was 914. The mean age of participants was 33.8 ± 9 years. The majority of participants were female 823 (90%); males 87 (10%). The vast majority (94%) agreed that breast milk is more beneficial than formula milk. Nearly two-thirds (61%) were continuously exposed to messages advertising formula feeding, compared to only 35% who were exposed to messages promoting BF. The study found that 67.2% accept BF in public places. Among male participants, only 49% accepted BF in public places compared to 79% of female participants who accepted it; p-value <0.001. Acceptability of BF in public places was significantly higher among participants who had family members who breastfed (68%), compared to those who did not (50%), (p-value 0.01).
