Birth weight and gestational age among children of Danish pharmacy assistants.

STUDY OBJECTIVE: The aim was to investigate whether specific types of work or exposures among pharmacy assistants were correlated with changes in birth weight or gestational age. DESIGN: The study was a nationwide historical cohort with open entry of all female members of the union of pharmacy assistants during 1979 to 1984. PARTICIPANTS: The cohort comprised 4939 pharmacy assistants under 40 years of age. The questionnaire was answered by 93%. MEASUREMENTS AND MAIN RESULTS: Information on birth weight and gestational age was obtained by linkage to the national birth register. Exposure information on type of work and exposure to pharmaceutical and chemical products during pregnancy was self reported. Only small and non-significant differences in birth weight and gestational age were found between the compared groups. Mean birth weight was 50 g above the national mean and gestational age was longer (p less than 0.0005). CONCLUSIONS: Compared to the Danish population, children of pharmacy assistants are at low risk for experiencing low birth weight and preterm birth. Social status and less smoking during pregnancy among pharmacy assistants might explain the slightly greater mean birthweight and gestational age in this sector of the population.

Congenital malformations and death among the offspring of Danish pharmacy assistants.

Congenital malformations, stillbirth, and infant mortality were studied in a cohort of all female pharmacy assistants in Denmark under the age of 40 years who were members of the national union in 1979 to 1984 (4,939). Data on all births and deaths during first year of life during the study period were identified through the national birth register. Information on type of work, exposures, and life-style variables were obtained by postal questionnaires, to which 93% responded. In general, pharmacy assistants had a low frequency of congenital malformation and death among their offspring. Compared with an internal reference group, pharmacy assistants engaged in production or packing of pharmaceutical products experienced an increased prevalence of congenital malformations among their offspring. Working with identification and controls showed a slightly increased risk of death during the first year of life of the children. This could indicate occupational risks, but other explanations cannot be excluded.

Time to pregnancy--a model and its application.

Biological fertility is poorly measured by the number of children born in industrially advanced societies. The time elapsing from when a couple decides to have a child to clinically recognizable pregnancy is a useful alternative. Time to pregnancy can be collected in broad categories in large samples. A model for condensing important information from such data is presented, which fits several large samples of reported waiting times. It is shown that multiparous women conceive more quickly than primiparous women.

Risk of spontaneous abortion among Danish pharmacy assistants.

A national study of the risk of medically verified spontaneous abortion was conducted among all pharmacy assistants in Denmark. The cohort was defined as 4939 female members of the Association of Danish Pharmacy Technicians between 1979 and 1984, all under the age of 40 years. Data on spontaneous and induced abortions, and births as well, were obtained from the national registers from the same time period. Data on work history and exposure to pharmaceuticals and chemicals were collected from self-administered postal questionnaires in April 1985 with a response rate of 93%. Studies of spontaneous abortion give rise to many methodological problems. In this study data were analyzed in a case-referent model using pharmacy assistants in administration and at the counter as the reference group. Generally, pharmacy assistants are at low risk with respect to spontaneous abortion. However, a few statistically significant results were found, but a decision on their importance must await further research.

Time to pregnancy among Danish pharmacy assistants.

Time to pregnancy was studied as a parameter of couple fertility in a national cohort of all female members (less than 40 years) of the union of pharmacy assistants from 1979 to 1984. A total of 4 924 women were included in the study. Information on time to pregnancy and exposure was obtained by postal questionnaires in April 1985 (response rate 92%). Prolonged time to pregnancy according to occupation in production or a dispensary or in product control, bottling, and packing is presented, unexposed pharmacy assistants being used as referents. It was possible to use time to pregnancy in an occupational setting as 95% of the women were able to state their time to pregnancy and as 90% of all pregnancies were planned. No association was found between type of work or pharmacy and time to pregnancy, but pharmacy assistants exposed to antibiotics had a slightly increased risk of prolonged time to pregnancy.

[The influence of chemical occupational environmental factors on reproduction in women in various occupations].

This review is a survey of the literature on reproductive health effects to female workers exposed to chemicals in different occupations. Epidemiological studies on fertility, spontaneous abortions, congenital malformations, preterm birth, and perinatal death is discussed. The article describes the possible reproductive hazards in occupations with exposure to pesticides, solvents, pharmaceutical products, textile colours, antineoplastic plastic drugs, anaesthetic gases, plastfumes, and metals. Finally the importance of prevention and further research in this area is stated.

[The effect of physical working conditions on female reproduction].

The reproductive hazard of ionizing radiation has been known for half a century. In the last decade studies have demonstrated that many other physical conditions in the working environment affect human reproduction. Micro- and shortwaves are under suspicion of increasing the risk of malformations. The association between work at video display terminals and a raised risk of spontaneous abortion has not been confirmed. The slight suspicion of reduced birth weight in ultrasound exposed fetuses and the association between noise and preterm birth/low birth weight need further investigation. No reproductive hazard has been reported for women in cold or warm working environments. Physical effort and heavy lifting increase the risk of spontaneous abortion and preterm birth/low birth weight.
