Objective To examine the effects of tea consumption during pregnancy on the risk of pre‐eclampsia. Methods A case‐control study was carried out among nulliparous pregnant women in Quebec between January 2003 and March 2006. Data were collected using a structured study questionnaire. A total of 92 women with pre‐eclampsia and 245 controls were analyzed. Univariate analysis and multivariate regression were performed to examine the association between tea consumption and pre‐eclampsia. Results Compared with non‐tea drinking during pregnancy, the crude odds ratio (OR) and adjusted OR (aOR) of pre‐eclampsia for tea drinking were 1.34 (95% CI, 0.80–2.25) and 1.39 (95% CI, 0.81–2.41), respectively. The OR and aOR of severe pre‐eclampsia for tea drinking were 1.39 (95% CI, 0.78–2.46) and 2.14 (95% CI, 1.01–4.54), respectively. The aORs for persistent tea consumption in pre‐eclampsia and severe pre‐eclampsia were 1.88 (95% CI, 1.01–3.51) and 1.95 (95% CI, 1.06–3.57), respectively. Conclusion Persistent tea drinking during pregnancy may be associated with an increased risk of pre‐eclampsia.
