69; 95% CI 0.49–0.99). Fish oil supplementation in women

with previous pregnancy complications showed more advanced gestational age at delivery in low and middle (but not high) fish consumers [286]. After contradictory pilot trial findings [287], [288] and [289], vitamins C and E do not decrease preeclampsia risk; rather, they are more frequently associated with birthweight <2.5 kg and adverse perinatal outcomes [290], [291], [292] and [293]. 1. There is insufficient evidence to make a recommendation about the usefulness of the following: new severe dietary salt restriction for women with any HDP, ongoing high throughput screening compounds salt restriction among women with pre-existing hypertension, heart-healthy diet, and calorie restriction for obese women (all III-L; all Very low/Weak). We lack RCT evidence examining the impact of the following on HDP outcomes: new severe GSI-IX molecular weight dietary salt restriction for women with any HDP, new or ongoing salt restriction among women with pre-existing hypertension, heart healthy diet, calorie restriction among overweight women, or the impact of exercise. Preeclampsia is listed as a contraindication to vigorous exercise in the relevant SOGC 2003 Clinical Practice Guidelines [294]. No RCT data support workload reduction/cessation

or stress management (e.g. meditation) for any of the HDPs when they are non-severe and outpatient-managed. Outside pregnancy, stress management by relaxation techniques may improve BP control [7]. Bed rest is standard for women with a HDP [295] and [296]. Definitions have varied widely, compliance questioned [279], and RCT data are limited. For preeclampsia, strict (vs. some) bed rest in hospital MYO10 does not alter outcomes [297]. For gestational hypertension, some bed rest in hospital (vs. routine activity at home) decreases severe hypertension (RR 0.58; 95% CI 0.38–0.89) and preterm

birth (RR 0.53; 95% CI 0.29–0.99), although women prefer unrestricted activity at home [296]; whether benefits are from bed rest or hospitalization is not clear. In the absence of clear benefit, bed rest cannot be recommended due to potential harmful physical, psychosocial, and financial effects [298] and [299]. We found no cost effectiveness studies of dietary and lifestyle changes for HDP management. The following recommendations apply to women with either pre-existing or gestational hypertension. 1. In-patient care should be provided for women with severe hypertension or severe preeclampsia (II-2B; Low/Strong). Out-of-hospital care for preeclampsia assumes that full maternal and fetal assessments have been made and severe disease excluded (see Classification of HDP). Options include obstetrical day units and home care. Eligibility depends on home-to-facility distance, adequate maternal and fetal surveillance, patient compliance, non-labile BP, and absence of comorbid conditions or disease progression. Hospital day units. Eligibility has varied from 30 to 60% of women assessed [300] and [301].
