Sex and gender in hypertension guidelines

Abstract

AbstractThis paper reviews 11 current and previous international and some selected national hypertension guidelines regarding sex and gender-related differences. Those differences can be attributed to biological sex and to gender differences that are determined by socially constructed norms. All reviewed guidelines agree on a higher hypertension prevalence in men than in women. They also concur that evidence does not support different blood pressure thresholds and targets for treatment between men and women. Differences refer in addition to the differences in epidemiological aspects to differences in some morphometric diagnostic indices, e.g., left ventricular mass or the limits for daily alcohol intake. Concerning practical management, there are hardly any clear statements on different procedures that go beyond the consensus that blockers of the renin–angiotensin system should not be used in women of childbearing age wishing to become pregnant. Some further sex-specific aspects are related to differences in tolerability or drug-specific side effects of BP-lowering drugs. There is also a consensus about the need for blood pressure monitoring before and during the use of contraceptive pills. For management of pregnancy, several guidelines still recommend no active treatment in pregnant women without severe forms of hypertension, despite a wide consensus about the definition of hypertension in pregnancy. A disparity in treatment targets when treating severe and non-severe hypertension in pregnancy is also observed. Overall, sex-specific aspects are only very sparsely considered or documented in the evaluated guidelines highlighting an unmet need for future clinical research on this topic.
