abstract：PURPOSE:Studies have shown that absolute intensity of physical activity is associated with reduced risk of preeclampsia. This analysis was performed to examine whether relative intensity may also be related to preeclampsia risk. METHODS:Using data from a case-control study conducted from 1998 to 2002, the authors asse...
