Research

Socioeconomic status and perinatal health
Although the Canadian health care system is designed to provide accessible and universal obstetric, neonatal and pediatric care for its citizens, it is necessary to examine if all socioeconomic groups experience healthy maternal, fetal and infant outcomes. Such studies are important for identifying potential deficiencies within the health care system and for targeting vulnerable subpopulations with appropriate public health programs.

The increasing ability to link perinatal health databases with others that contain socioeconomic information (through a highly secure and confidential process) allows such public health objectives to be met. This research will also attempt to isolate the component of perinatal health that is a consequence of the social determinants and is distinct from health care interventions.

My colleagues and I are in the process of carrying out studies (using CIHR funding) that examine rates of labour induction, cesarean delivery, pregnancy complications, perinatal mortality, serious neonatal morbidity and infant death by family income and other indices of socioeconomic status.

Natural history of pregnancy
Despite substantial advances in obstetrics in recent decades, obstetric theory has yet to satisfactorily resolve various conundrums that plague the perinatal domain.

Whereas the frequency of perinatal outcomes declines exponentially with increasing gestational duration, gestational age distributions in industrialized countries have ‘shifted to the left’ as a consequence of medically indicated early delivery. This is evident from recent increases in preterm birth and declines in post-term birth.

Various other problems also plague the perinatal literature including issues related to the patterns of fetal growth restriction and the paradox of intersecting perinatal mortality curves. Fetal growth related issues are a confusing topic and this is highlighted by the disconnection between stable rates of growth restriction across gestation and the exponential decline in perinatal mortality with increasing gestational age.

The paradox of intersecting perinatal mortality curves is another highly intriguing phenomenon, first described over 4 decades ago, which shows that perinatal death rates are lower among low birth weight fetuses/infants of smokers compared with those of non-smokers. The reverse is true at higher birth weight and the phenomenon is also seen in contrasts between singletons and twins, across parity, infant gender, country and other determinants of birth weight.

The recent extension of the fetuses-at-risk approach to embrace all pregnancy related phenomena including birth, growth restriction and perinatal mortality/morbidity provides an explanation that resolves these various paradoxes. However, the theory remains controversial. Further work on the natural history of pregnancy and on descriptive versus causal epidemiologic models is necessary to develop a fully coherent framework that describes the natural history of pregnancy and which includes an epidemiologic justification for medically indicated early delivery.

My colleagues and I propose to work on these issues using data from large perinatal databases including the British Columbia Perinatal Database Registry and the United States NCHS perinatal mortality datafiles.
