This research aims to identify factors associated with exclusive breastfeeding failure in the Aceh Province. The method used is an analytical survey with a cross-sectional design. The study population comprises all mothers with infants aged 6-12 months in Aceh Besar district and Sabang City. The study was conducted in the Aceh Besar Health Office and Sabang City working area from January to December 2022. The measurement tool used was a questionnaire. Data analysis was performed using the chi-square test. The study results show that lack of cultural support for exclusive breastfeeding increases the likelihood of complete breastfeeding failure by 1.7 times, and there is a statistically significant relationship (p = 0.0001). Lack of support from healthcare providers increases the likelihood of exclusive breastfeeding failure by 3.5 times, and there is a substantial relationship with a p-value of 0.0001 (p < 0.05). Caesarean section (C-section) as a maternal factor increases the likelihood of exclusive breastfeeding failure by 1.5 times, but there is no statistically significant relationship (p = 0.104). Low birth weight infants have a 3.2 times higher likelihood of exclusive breastfeeding failure but no statistically significant relationship (p = 0.052). Lack of support from the husband for exclusive breastfeeding increases the possibility of complete breastfeeding failure by 1.8 times, and there is a significant relationship with a p-value of 0.014 (p < 0.05). Efforts are needed to overcome challenges in achieving optimal exclusive breastfeeding coverage in the region, especially in areas with low range, such as Sabang City. Cultural factors that influence the early introduction of food and drinks to newborns also need to be addressed through programs that educate the community about the benefits and proper practices of exclusive breastfeeding.
