To investigate the association between emotional responses to climate change, antenatal anxiety, and maternal-fetal attachment in primigravida women. A multi-site cross-sectional research design study. This study was conducted at four primary health care (PHC) facilities in Damanhur district, El-Behera, from February 2024 to April 2024. Two hundred eighty-five women completed a comprehensive questionnaire that included a Woman's Social and Reproductive Form, The inventory of climate emotions (ICE) scale, The Stirling Antenatal Anxiety Scale (SAAS) and the Maternal-Fetal Attachment Scale (MFAS-HU-20). The study revealed that emotional responses to climate change show strong positive correlations with each other, ranging from 0.689 to 0.840, all significant at p < 0.001 level. Additionally, antenatal anxiety demonstrates substantial positive correlations with emotional responses to climate change, albeit with associations ranging from 0.239 to 0.287, all significant at p < 0.001 level. Moreover, maternal-fetal attachment displays substantial negative correlations with emotional responses to climate change, indicating that as emotional responses to climate change increase, maternal-fetal attachment tends to decrease. The correlations range from -0.263 to -0.426, all significant at p < 0.001. The emotional impact of climate change can adversely affect the bonding process between mother and fetus.
