[A retrospective analysis of aborted pregnancy in women engaged in agricultural production in controlled areas of Ukraine]. / Retrospektivnyi analiz nedonoshennoi beremennosti u zhenshchin, zaniatykh v sel'skokhoziaistvennom proizvodstve kontroliruemykh territorii Ukrainy.

A retrospective analysis was carried out of failure for a woman to be delivered of a child at the natural time in those female workers engaged in agricultural production in controlled territories of Ukraine (Narodichi and Ovruch districts of Zhytomir Province). Data files were studied of 5371 histories of labor (2440 those before and 2931 after the Chernobyl accident) and 525 records of spontaneous abortion (255 those before and 27 after the ChNPP breakdown). There has been found relationship between the frequency of incomplete pregnancies and density of contamination of soil with cesium-137 in certain settlements.

Health effects of pesticides on female beet growers.

The working conditions of female beet growers and their health effects were studied. Dust, chemical substances, physical strain and the forced working posture were among the occupational factors producing adverse health effects. Contact with pesticides is believed to be the major factor in the development of chronic pathology and temporary disability among female beet-growers. There is a need to promote a system of preventive measures, including comprehensive biological monitoring and control of pesticide concentrations in the environment.

[Fertility and reproduction in women working in beet growing and animal breeding (1943-1982)]. / Plodovitost' i rozhdaemost' u zhenshchin, rabotavshikh v sveklovodstve i zhivotnovodstve s 1943 po 1982 g.

The article contains formulae for real fertility rate (RFR), functional and calendar-related pregnancy intervals. RFR is proposed as the criteria in the assessment of occupational factors' influence on the reproduction function in couples not using contraceptives. The simultaneous reproduction assessment with two indices involved (real fertility and birthrate) made it possible to evaluate the role of the occupational and social factors in human reproduction in the region. The agricultural female workers surveys showed that RFR remained stable at the time of examinations and births, taking account of the age, in women engaged in beet raising, cattle breeding and employees, who had been working in different labour conditions for 40 years. Within the same period of time, birth rates in the beet-raisers were markedly higher as compared with the employees.

PIP: To evaluate the indices of physiological fertility in female agricultural workers, the outcomes of 24,153 pregnancies registered in the period from 1943 to 1982 in various beet growing and animal breeding regions of Ukraine were analyzed. More than one half of all pregnancies (63.9%) were recorded in women 30 years old. On average, a woman had 5.05 pregnancies; 47.4% of pregnancies terminated in normal delivery, 48.3% in abortion, and 3.7% in miscarriage (0.6% were extrauterine pregnancies). Average duration of the active ovarian function (from the onset of menstruation to the menopause) was 33.0 years. Occupational hazards included physically demanding work, exposure to dust, pesticides, fertilizers, and animal feed. It was suggested that the factual fertility is best characterized not by the birth rate but by the functional and calendar interval between pregnancies coupled with fertility coefficients (intensity of conceptions in unit of time) in women who did not use the contraceptive agents. For the given cohort, the functional interval between conceptions (refractory period) and actual fertility rate (AFR) were calculated. During the most active child bearing period (up to 40 years of age), the AFR was 5.27% in beet growers, 6.83% in animal breeders, and 6.04% in white collar workers. For the entire child bearing period (from 17 to 50 years of age), AFR ranged from 3.36 to 4.99%. The functional and calendar intervals between pregnancies showed gradual increase with age (from 10.1 months to 200 months). In a 25-29-year-old group, the interval between pregnancies was 17,1 months for beet growers, 12.0 months for animal breeders, and 18.7 months for white collar workers.

[Gynecologic morbidity among workers at soil and hydroponic hothouses]. / Ginekologicheskaia zabolevaemost' rabotaiushchikh v pochvennykh i gidroponnykh teplitsakh.

Data are analyzed on the frequency of gynecological diseases during the first three years of work in hothouses. There were no differences in the frequency of gynecological diseases, complications of pregnancy course and labour during adaptation to working conditions in the hothouses. In women with a 10-year length of work in hothouses, disorders of the menstrual cycle were more frequent than among women of the administration.
