We examined population-based data up to April 2019 from Quebec province, Canada (health administrative databases, birth, stillbirth and death registries). The primary exposure was cumulative gestational diabetes, gestational hypertension and preeclampsia occurrences across two pregnancies.

Compared with no gestational diabetes or gestational hypertension\/preeclampsia occurrences in partners, the hazards of diabetes in fathers increased by 21% with a single occurrence (HR 1.21, 95%\u2009CI 1.16 to 1.26), 40% with two (HR 1.40, 95%\u2009CI 1.30 to 1.50) and 84% with three or more (HR 1.84, 95%\u2009CI 1.54 to 2.21). Corresponding increases in hypertension hazards were 11% (HR 1.11, 95%\u2009CI 1.08 to 1.14), 17% (HR 1.17, 95%\u2009CI 1.12 to 1.23) and 39% (HR 1.39, 95%\u2009CI 1.22 to 1.58), respectively.
