Mothers who had HDP exposure were significantly associated with an increased risk of total CHDs compared with non-exposure. When maternal HDP exposure was further subdivided into pre-eclampsia (\n                      <jats:italic>OR<\/jats:italic>\n                      = 1.79, 95% CI: 1.50\u20132.13), gestational hypertension (\n                      <jats:italic>OR<\/jats:italic>\n                      = 1.16, 95% CI: 1.02\u20131.31), and chronic hypertension (\n                      <jats:italic>OR<\/jats:italic>\n                      = 1.68, 95% CI: 1.49\u20131.89), a significantly increased risk of total CHDs were still presented.
