Reports of environmental problems in the former Soviet Union, including excess use of pesticides, have led to concerns about high levels of contamination in humans, but little information is available to assess whether these concerns are warranted. Samples of breast milk from 197 women from two cities in Ukraine were analyzed for p,p'-DDT, p,p'-DDE, endrin, dieldrin, heptachlor epoxide, trans-nonachlor, oxychlordane, hexachlorobenzene, ss-hexachlorocyclohexane (HCH), and 18 polychlorinated biphenyl congeners, and results were compared to previous reports from Europe. The median ss-HCH concentration was 731 ng/g milk fat, which is higher than other reports from Europe but lower than reports from other parts of the world. The median DDE concentration was 2,457 ng/g milk fat, which is higher than most but not all other reports from Europe. Concentrations of other chemicals were comparable to or lower than other reports from Europe. Concentrations from the city of Kyiv were generally lower than those from Dniprodzerzhinsk, but the magnitudes of these differences were modest.

OBJECTIVES: Frequent terminations of pregnancy and high rates of fetal loss have been reported, but not confirmed, in the former eastern bloc. A census of pregnancies in Ukraine, a former eastern bloc country, was conducted to determine the rates of these events. METHODS: All pregnancies registered in 2 urban areas were enumerated. During a 19-month period between 1992 and 1994, 17,137 pregnancies and their outcomes were recorded. RESULTS: Sixty percent of the pregnancies were voluntarily terminated, generally before the 13th week. In pregnancies delivered at 20+ weeks, fetal mortality was 29 per 1000, nearly 5 times the rate among Whites in the United States. There was a greater proportion of very early deliveries (20-27 weeks) in Ukraine, as well as higher death rates at all gestational ages. Perinatal mortality was estimated to be 35 per 1000, about 3 times the US rate. CONCLUSIONS: This is believed to be the first study in the former eastern bloc to ascertain all of the clinically recognized pregnancies in a specified period and to determine their outcomes. The data document elevated reproductive risks in a former Soviet state.

The economic, social and health problems faced by former eastern bloc countries after the demise of the Soviet Union are unique in the recent history of Europe. We conducted a study in two urban areas of Ukraine, asking if the traditional predictors of preterm delivery continue to be associated with risk under these conditions. Subjects were pregnant women with last menstrual period (LMP) between 25 December 1992 and 23 July 1994. Self-completed questionnaires and the medical record provided data. We compared 137 spontaneous preterm deliveries with 2,886 full-term births, using all established risk factors for which we had data. Maternal age was the variable most strongly related to preterm birth. Being 18 or less had an odds ratio (OR) of 3.7; being 30+ had an OR of 2.5 relative to the reference group of age 25-29. Placental complications and pre-existing hypertension had ORs of 2.7 and 2.3, respectively, but the confidence interval included 1.0. Low net pregnancy weight gain (less than 10 kg) was significantly associated with preterm birth, but the rate of net weight gain was not. Marital status and educational category were only weakly related. We conclude that although Ukraine faced serious difficulties during its transition to a market economy, these problems did not generally alter the outcome of pregnancy in our sample when the classic risk factors for preterm delivery were present.

Live-born preterm birth rates are influenced by whether infants survive to be included in calculations. The high fetal mortality rate in Ukraine causes many preterm births to be excluded, thus lowering the rate. Frequent pregnancy termination and lack of ultrasound dating in Ukraine also might cause the preterm birth rate to be lower. Preterm birth rates, especially among live-born infants, are difficult to interpret and treacherous to compare across nations. Survival of the fetus and its health and development at birth are better indicators of reproductive outcome.

Family and Children of Ukraine, the Ukrainian component of the European Longitudinal Study of Pregnancy and Childhood, is a prospective, geographically-based study to evaluate pregnancy outcomes in 8,000 women in five cities in Ukraine and follow the cohort of births through 7 years of age. Family and Children in Ukraine has been the major collaborative research project for the University of Illinois' Fogarty-funded program, International Training and Research in Environmental and Occupational Health. This Fogarty program includes graduate training, U.S.-based training of visiting scientists, in-country training, and collaborative in-country research. Factors that have contributed to the success of the collaboration include: 1) its focus on the environmental health of mothers and children, which is a priority goal for both countries; 2) the adoption of an internationally-endorsed research protocol with strict quality-control criteria, specifically designed for international collaboration; 3) the establishment of an in-country data management center; and 4) the investment in a long-term research program rather than a short-term study. The major obstacles have been the difficult economic situation in Ukraine, which limits in-country research investment, and the difficulty in obtaining U.S. funding for an international research program.

Hospital admissions are generally regarded as a marker of severe pregnancy complications, and a low ratio of antenatal admissions to deliveries is considered an indicator of maternal-fetal well-being. We investigated the reasons for hospital admissions in a sample of deliveries from Ukraine, a country of the former eastern bloc. All hospitalisations were traced among 3099 women who delivered live singletons of at least 20 weeks gestation in two urban areas of Ukraine and data were abstracted from their medical records. More than a third of the women were admitted to hospital during their pregnancy, and 91% of the admissions were for a pregnancy complication, primarily threatened abortion or early labour. Median length of stay for all admissions was 12 days. The ratio of admissions to deliveries was 52 per 100. The Ukrainian ratio of hospitalisations to deliveries is notably higher than any that have been published in studies from the United States and Australia, reflecting patterns of care that stress hospital-based treatment. This high ratio does not necessarily mean that Ukrainian women are sicker, although that may be the case. The comparison of hospitalisation to delivery ratios is meaningful only when other factors, such as resources, patterns of care, costs and access, are taken into account.
