Among women with no hypertension in an index pregnancy, increased delivery-to-delivery weight gain was associated with an increased risk of hypertensive disorders in a subsequent pregnancy, a new study found. The case-control study included women who had 2 live singleton births of at least 24 weeks of gestation at a single maternity hospital from January 1, 2005, to December 31, 2015, with no hypertensive disorder at index pregnancy. Among the details:
- Of 1,033 women, 188 (18.2%) were diagnosed with a hypertensive disorder in the subsequent pregnancy; of these, 166 (88.3%) had a hypertensive disorder specific to pregnancy.
- An increase of body mass index (BMI) of at least 2 kg/m2 between deliveries was independently associated with an increased risk of a hypertensive disorder in a subsequent pregnancy (adjusted odds ratio [OR] 1.76).
- Conversely, weight loss of 2 kg/m2 or more was associated with a decreased risk of a hypertensive disorder (adjusted OR 0.41).
