Vaginal douching and reduced fertility
OBJECTIVES: This study investigated douching and reduced fertility. METHODS: The monthly probability of conception for douchers and nondouchers was compared in a sample of 840 married, parous women in King County, Washington. Data on the number of months required to conceive were analyzed. RESULTS: In comparison with nondouchers, women who douched were 30% less likely to become pregnant each month they attempted pregnancy. This relationship remai…
Pregnancy risk factors and birth outcomes in Washington State
This study compared birth outcomes of three cohorts of women with singleton live births in Washington State between 1980 and 1991: all Black Ethiopian-born women (n = 264) and samples of US-born Black (n = 526) and White (n = 546) women. Ethiopians were older, more likely to be married, and less likely to smoke than were US-born women, and they were less likely to have anemia than US-born Blacks. The adjusted low-birthweight risk among Ethiopians…
Exposure to hair-coloring products and the risk of multiple myeloma
An interview study of persons diagnosed with multiple myeloma between 1977 and 1981 and suitable control subjects was conducted to test the hypothesis that exposure to hair dyes increases the risk of multiple myeloma. Among women, there was little evidence that prior regular use of hair dyes (odds ratio [OR] = 1.0; 95% confidence interval [CI] = 0.70, 1.4) or prior employment as a hairdresser (OR = 1.1; 95% CI = 0.43, 2.7) increased risk; however…
Prevalence and determinants of caesarean section in Jamaica
The prevalence and determinants of primary caesarean section in Jamaica were estimated from a survey of women aged 14–49 years. Among 2328 women reporting 2395 live hospital births during the period January 1984 to May 1989, the prevalence of caesarean section was 4·1%. Repeat caesarean sections accounted for 1·3% of the hospital births during that period. Of the medical complications studied, prolonged labour and/or cephalopelvic disproportion c…
Current cigarette smoking and risk of acute pelvic inflammatory disease
OBJECTIVES. Further information is needed on modifiable factors associated with the occurrence of acute pelvic inflammatory disease (PID). Cigarette smoking has been implicated as a risk factor for PID sequelae, but the association between smoking and PID has yet to be fully examined. METHODS. We conducted a population-based case-control study to evaluate smoking as a risk factor for acute PID. The case patients (n = 131) were women health mainte…
Low birth weight in relation to multiple induced abortions
BACKGROUND. Most studies report that a single induced abortion does not increase risk for delivering a low birth weight infant in a subsequent pregnancy. However, the effect of multiple abortions has not been adequately evaluated. METHODS. This relationship was studied in 6541 White women who delivered their first child between 1984 and 1987. We compared the frequencies of low birth weight (less than 2500 g) among infants born to 1999 women witho…
Advanced maternal age as a risk factor for cesarean delivery
The rate of delivery by cesarean has increased steadily in the United States since the 1970s. The reasons for this increase are not fully established. Improved diagnosis of maternal and fetal complications, medicolegal concerns, and the changing age composition of childbearing women have been cited as contributing factors. To assess whether advanced maternal age by itself is an indicator for a primary cesarean delivery, we analyzed data from the …
Secular change in birthweight among southeast Asian immigrants to the United States
We analyzed the Washington State births in 1980-1986 to Southeast Asian parents whose birth place was coded as being outside of the US. The mean birthweight increased from 3188 grams in 1980-81 to 3283 grams in 1986, an annual increment of about 18 grams (95% CI = 11, 25 grams). The prevalence of low birthweight (less than 2500 grams) decreased from 7.2 percent in 1980-81 to 5.4 percent in 1986, an annual reduction of 6.4 percent (95% CI = 1.3, 1…
Prior condom use and the risk of tubal pregnancy
The relationship between prior condom use and tubal pregnancy was assessed in a population-based case-control study at Group Health Cooperative of Puget Sound during 1981-86. We interviewed 227 women with a tubal pregnancy who had no clinical indication of infertility and no history of sterilization and 674 similarly defined controls who were matched to the cases on age and county of residence. A history of condom use for more than one year was a…
Prior cesarean delivery in women with secondary tubal infertility
The history of cesarean delivery was evaluated in a population-based case-control study of secondary infertility in King County, Washington. Sixty-one married women diagnosed with secondary infertility due to tubal problems who had a previous viable pregnancy were compared to 343 married women who had a previous viable pregnancy and then had a live birth that was conceived at the same time the infertile women began trying to conceive. The risk of…
Induced abortion and the risk of subsequent ectopic pregnancy
This study assessed the effect of legal induced abortion on ectopic pregnancy risk by using a comparison group of reproductive-age women who were at risk of becoming pregnant during the same time period the women with ectopic pregnancy conceived. Cases were members of Group Health Cooperative of Puget Sound who were hospitalized for ectopic pregnancy from October 1981 through September 1986 (N = 211). Controls were randomly selected members match…

Evaluating the risks of cesarean section
Data from Washington State birth certificates from 1980-83 were used to estimate excess risk to the infant delivered via repeat cesarean section independently of any risk associated with the indication for the procedure. Using a case-control design, we compared the method of delivery of all infants with low (0-6) five-minute Apgar scores born to multiparous mothers after uncomplicated pregnancies and births to that of similar infants with a high …
Bias resulting from using the card-back system to contact patients in an epidemiologic study
In a case-control study of thyroid cancer in women in western Washington, the card-back system was used to contact patients. Demographic characteristics and reproductive history of 124 cases who returned a card and 35 who did not were compared, and were found to differ with respect to various reproductive and demographic factors. Relative risk estimates for various thyroid cancer risk factors were calculated two ways: including as cases only thos…
IUD use and subsequent tubal ectopic pregnancy
As part of a case-control study of tubal ectopic pregnancy (TEP), we sought to evaluate the possible etiologic role of use of an intrauterine device (IUD) prior to conception. We interviewed 155 women who had a tubal ectopic pregnancy treated at one of five Seattle, Washington hospitals between 1975-79 regarding their reproductive, contraceptive, and medical histories; 456 women who delivered a baby in King County during the same period were iden…
Level of response in epidemiologic studies using the card-back system to contact subjects
Response levels obtained from two methods of patient contact to obtain subject consent for participation in epidemiologic studies were compared. When a signed, return card was required prior to further contact, 70 to 83 per cent of patients consented to participate, compared with consistently higher levels (89 to 93 per cent) obtained with telephone contact. These data suggest that the likelihood of obtaining the high response level required in e…
Exercise as a risk factor for infertility with ovulatory dysfunction
To examine the relation of regular vigorous exercise to ovulatory infertility, we interviewed 346 infertile women, in whom there was evidence of ovulatory failure, regarding their exercise patterns during the year preceding their unsuccessful effort to conceive. Their responses were compared with similar exercise histories in women who had successfully conceived at the time the infertile women started trying to become pregnant. Vigorous exercise …

Control definition in case-control studies of ectopic pregnancy
In case-control studies of ectopic pregnancy, the optimal sampling frame for control selection is influenced heavily by the hypothesis being tested. The selection of women completing an intrauterine pregnancy, a common choice for a control group in studies to date, is appropriate only if the hypothesis does not relate to exposures that selectively prevent an intrauterine pregnancy (e.g., use of an intrauterine device (IUD) at the time of concepti…
Prenatal care and pregnancy outcomes during the recession
To determine whether changes in prenatal care utilization and adverse pregnancy outcomes occurred among poor residents of Washington State during the recent recession, we examined all births occurring from 1980 to 1983 to women in the poorest census tracts of the three major metropolitan counties in Washington State (N = 15,735). A comparison sample consisted of all births occurring in the highest income census tracts (N = 16,295). Because the im…
Tubal Infertility in Relation to prior induced Abortion
One hundred twenty-seven women who had been given diagnoses of tubal infertility between 1979 and 1981 in King County, Washington, yet previously had been pregnant, were interviewed to determine their prior history of legally induced abortion. Their responses were compared with those of 395 women who conceived a child at the same time the infertile women began their unsuccessful attempt to become pregnant. In making the comparison, we adjusted fo…
