The connection between psychiatric morbidity and HG has been debated, but only a few studies have focused on eating disorders (EDs). The objective of this study was to evaluate the association between HG and both pre\u2010pregnancy and new post\u2010pregnancy EDs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A register\u2010based controlled study. HG diagnoses were retrieved from healthcare registers between 2005 and 2017. Women with HG in their first pregnancy resulting in delivery were chosen as cases (<jats:italic>n<\/jats:italic>\u2009=\u20094265; the HG group) and women with no HG as controls (<jats:italic>n<\/jats:italic>\u2009=\u2009302,663; the non\u2010HG group). The associations between EDs and HG were analyzed by binary logistic regression, adjusted with age, body mass index, smoking, socioeconomic status, and pre\u2010pregnancy psychiatric diagnoses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the HG group, 1.6% and in the non\u2010HG group, 0.2% had a pre\u2010pregnancy ED. Women with ED were more likely to have HG in their first pregnancy compared with women with no history of EDs (adjusted odds ratio [AOR] 9.4, 95% CI 6.52\u201313.66, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001). Moreover, 0.4% of the women in the HG group and 0.1% of the women in the non\u2010HG group had a new ED diagnosis after pregnancy, and thus the women in the HG group were more likely to have an ED diagnosis after pregnancy (AOR I 3.5, 95% CI 1.71\u20137.15, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001, AOR II 2.7, 95% CI 1.30\u20135.69, <jats:italic>p<\/jats:italic>\u2009=\u2009.008).<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>We found a bidirectional association between ED and HG, suggesting a shared etiology or risk factors between these disorders.

This finding provides essential information for healthcare professionals working with pregnant women.
