Sarka Lisonkova
PhD, MD

Investigator, BC Children's Hospital

My research interest is in perinatal epidemiology, including pregnancy complications, fetal and neonatal outcomes and maternal morbidity. My recent and current research projects have used epidemiological methods to examine the risk factors and consequences of early- and late-onset preeclampsia on fetal and infant outcomes, and trends in maternal mortality in Canada. Other areas of research interest include the effects of older maternal age on pregnancy outcomes, assisted reproduction, preterm birth, and neonatal mortality and morbidity. I am particularly interested in using perinatal databases to address problem of health status and health care.

My goal is to advance the scientific knowledge-base related to the etiology of pregnancy complications, preterm birth, and severe maternal morbidity, and to improve maternal and child health in British Columbia, Canada and elsewhere.

Population-based study of fertility drug use

Fertility drug treatments are more prevalent than other assisted reproductive techniques (e.g., in vitro fertilization) in many jurisdictions, and may have a larger effect on the rate of multiple pregnancies than other ART. Nevertheless, population-level information on fertility drug use is virtually non-existent in North America. My study showed that approximately 3 per 1000 women in British Columbia use the fertility drug clomiphene citrate, and that new treatment initiation increased between 2000 and 2008 among older women. In my next study on this issue I propose to examine the effect of fertility drug use on population rates of multiple pregnancy, preterm birth and adverse perinatal outcomes, and long-term effects of clomiphene citrate on women’s health.

International comparisons of preterm birth rates and effects on perinatal mortality

Although preterm birth is the most important perinatal challenge facing industrialized countries, recent increases in iatrogenic preterm birth have made this a complex index, affected not only by overall perinatal health but also by the level of obstetric care/intervention. I and my colleagues showed that preterm births rates >= 32 weeks in industrialized countries are inversely associated with stillbirth rates and neonatal death rates >=32 weeks. I have proposed further research on determinants of different types of preterm birth, and the effect of iatrogenic delivery on maternal, fetal and infant health.

Studies on preeclampsia

Two of my recent studies have documented the incidence of preeclampsia across pregnancy and highlighted differences between early- and late-onset preeclampsia in terms of risk factors and fetal/infant and maternal adverse outcomes. I also proposed a plausible explanation for the intriguing inverse association between smoking and preeclampsia. I plan to further examine the methodological issue of competing risks in observational studies of pregnancy outcomes.
