Multicity HIV seroprevalence in street youth, Ukraine.

We conducted the first systematic, community-based, multicity assessment outside the USA of HIV seroprevalence, risk factors and linkage into clinical services among 929 street youth. After city-wide mapping, we used time-location sampling and randomly selected 74 venues in Odesa, Kyiv and Donetsk, Ukraine. Rapid HIV testing with post-test counselling was offered to all eligible youths aged 15-24 years. Overall, 18.4% (95% confidence interval 16.2-20.2) were HIV positive and 85% had previously unknown status. Rates were identical by sex. Subgroups with highest rates included orphans (26%), youths with histories of exchanging sex (35%), sexually transmitted infections (STIs) (37%), injection drug use (IDU) (42%) and needle sharing (49%). Independent predictors, similar across age groups and city, included being orphaned, time on the street, history of anal sex, STIs, exchanging sex, any drug use, IDU and needle sharing. Two-thirds (68%) of HIV-positive youths were linked to services. This high-risk population has many immediate needs.

Pregnancy intention and its relationship to birth and maternal outcomes.

OBJECTIVE: To examine whether there are associations between pregnancy intention (intended, unwanted, mistimed, or ambivalent) and negative birth and maternal outcomes: low birth weight (less than 2,500 g), preterm delivery (fewer than 37 weeks), small for gestational age, premature labor, hypertension, and other maternal outcomes. METHODS: We analyzed data from the population-based Pregnancy Risk Assessment Monitoring System, including 87,087 women who gave birth between 1996 and 1999 in 18 states. Information on pregnancy outcomes was derived from birth certificate data and a self-administered questionnaire completed postpartum. We employed SUDAAN (RTI International, Research Triangle Park, NC) for univariable and logistical regression analyses. RESULTS: In analyses controlling for demographic and behavioral factors, women with unwanted pregnancies had an increased likelihood of preterm delivery (adjusted odds ratio [OR] 1.16, 95% confidence interval [CI] 1.01-1.33) and premature rupture of membranes (adjusted OR 1.37, 95% CI 1.01-1.85) compared with women with intended pregnancies. Women who were ambivalent toward their pregnancies had increased odds of delivering a low birth weight infant (adjusted OR 1.15, 95% CI 1.02-1.29); in contrast, women with mistimed pregnancies had a lower likelihood (adjusted OR 0.92, 95% CI 0.86-0.97). CONCLUSION: Pregnancy intention, specifically unwanted and ambivalent, may be an indicator of increased risk for some poor birth and maternal outcomes and should be considered in interventions aimed at improving the health of the mother and child. LEVEL OF EVIDENCE: III.

Progestin and estrogen potency of combination oral contraceptives and endometrial cancer risk.

OBJECTIVE: Using data from a case-control study of endometrial cancer, we investigated the relationship between the progestin and estrogen potency in combination oral contraceptives (OCs) and the risk of developing endometrial cancer. METHODS: Subjects included 434 endometrial cancer cases and 2,557 controls identified from the Cancer and Steroid Hormone (CASH) study. OCs were classified into four categories according to the individual potencies of each hormonal constituent (high versus low estrogen or progestin potency). Logistic regression was used to evaluate associations between endometrial cancer risk and combination OC formulations. RESULTS: With non-users as the referent group, use of OCs with either high potency progestin [odds ratio for endometrial cancer (OR)=0.21, 95% confidence interval (CI)=0.10 to 0.43] or with low potency progestin (OR=0.39, 95% CI=0.25 to 0.60) were both associated with a decreased risk of endometrial cancer. Overall high progestin potency OCs did not confer significantly more protection than low progestin potency OCs (OR=0.52, 95% CI=0.24 to 1.14). However, among women with a body mass index of 22.1 kg/m2 or higher, those who used high progestin potency oral contraceptives had a lower risk of endometrial cancer than those who used low progestin potency oral contraceptives (OR=0.31, 95% CI=0.11 to 0.92) while those with a BMI below 22.1 kg/m2 did not (OR=1.36, 95% CI=0.39 to 4.70). CONCLUSION: The potency of the progestin in most OCs appears adequate to provide a protective effect against endometrial cancer. Higher progestin-potency OCs may be more protective than lower progestin potency OCs among women with a larger body habitus.

Reproductive factors and subtypes of breast cancer defined by hormone receptor and histology.

Reproductive factors are associated with reduced risk of breast cancer, but less is known about whether there is differential protection against subtypes of breast cancer. Assuming reproductive factors act through hormonal mechanisms they should protect predominantly against cancers expressing oestrogen (ER) and progesterone (PR) receptors. We examined the effect of reproductive factors on subgroups of tumours defined by hormone receptor status as well as histology using data from the NIHCD Women's Contraceptive and Reproductive Experiences (CARE) Study, a multicenter case-control study of breast cancer. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) as measures of relative risk using multivariate unconditional logistic regression methods. Multiparity and early age at first birth were associated with reduced relative risk of ER + PR + tumours (P for trend=0.0001 and 0.01, respectively), but not of ER - PR - tumours (P for trend=0.27 and 0.85), whereas duration of breastfeeding was associated with lower relative risk of both receptor-positive (P for trend=0.0002) and receptor-negative tumours (P=0.0004). Our results were consistent across subgroups of women based on age and ethnicity. We found few significant differences by histologic subtype, although the strongest protective effect of multiparity was seen for mixed ductolobular tumours. Our results indicate that parity and age at first birth are associated with reduced risk of receptor-positive tumours only, while lactation is associated with reduced risk of both receptor-positive and -negative tumours. This suggests that parity and lactation act through different mechanisms. This study also suggests that reproductive factors have similar protective effects on breast tumours of lobular and ductal origin.

Alcohol, tobacco and breast cancer--collaborative reanalysis of individual data from 53 epidemiological studies, including 58,515 women with breast cancer and 95,067 women without the disease.

Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58,515 women with invasive breast cancer and 95,067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19-1.45, P<0.00001) for an intake of 35-44 g per day alcohol, and 1.46 (1.33-1.61, P<0.00001) for >/=45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P<0.00001) for each additional 10 g per day intake of alcohol, i.e. for each extra unit or drink of alcohol consumed on a daily basis. This increase was the same in ever-smokers and never-smokers (7.1% per 10 g per day, P<0.00001, in each group). By contrast, the relationship between smoking and breast cancer was substantially confounded by the effect of alcohol. When analyses were restricted to 22 255 women with breast cancer and 40 832 controls who reported drinking no alcohol, smoking was not associated with breast cancer (compared to never-smokers, relative risk for ever-smokers=1.03, 95% CI 0.98-1.07, and for current smokers=0.99, 0.92-1.05). The results for alcohol and for tobacco did not vary substantially across studies, study designs, or according to 15 personal characteristics of the women; nor were the findings materially confounded by any of these factors. If the observed relationship for alcohol is causal, these results suggest that about 4% of the breast cancers in developed countries are attributable to alcohol. In developing countries, where alcohol consumption among controls averaged only 0.4 g per day, alcohol would have a negligible effect on the incidence of breast cancer. In conclusion, smoking has little or no independent effect on the risk of developing breast cancer; the effect of alcohol on breast cancer needs to be interpreted in the context of its beneficial effects, in moderation, on cardiovascular disease and its harmful effects on cirrhosis and cancers of the mouth, larynx, oesophagus and liver.

Adverse childhood experiences and sexual risk behaviors in women: a retrospective cohort study.

CONTEXT: Adverse childhood experiences such as physical abuse and sexual abuse have been shown to be related to subsequent unintended pregnancies and infection with sexually transmitted diseases. However, the extent to which sexual risk behaviors in women are associated with exposure to adverse experiences during childhood is not well-understood. METHODS: A total of 5,060 female members of a managed care organization provided information about seven categories of adverse childhood experiences: having experienced emotional, physical or sexual abuse; or having had a battered mother or substance-abusing, mentally ill or criminal household members. Logistic regression was used to model the association between cumulative categories of up to seven adverse childhood experiences and such sexual risk behaviors as early onset of intercourse, 30 or more sexual partners and self-perception as being at risk for AIDS. RESULTS: Each category of adverse childhood experiences was associated with an increased risk of intercourse by age 15 (odds ratios, 1.6-2.6), with perceiving oneself as being at risk of AIDS (odds ratios, 1.5-2.6) and with having had 30 or more partners (odds ratios, 1.6-3.8). After adjustment for the effects of age at interview and race, women who experienced rising numbers of types of adverse childhood experiences were increasingly likely to see themselves as being at risk of AIDS: Those with one such experience had a slightly elevated likelihood (odds ratio, 1.2), while those with 4-5 or 6-7 such experiences had substantially elevated odds (odds ratios, 1.8 and 4.9, respectively). Similarly, the number of types of adverse experiences was tied to the likelihood of having had 30 or more sexual partners, rising from odds of 1.6 for those with one type of adverse experience and 1.9 for those with two to odds of 8.2 among those with 6-7. Finally, the chances that a woman first had sex by age 15 also rose progressively with increasing numbers of such experiences, from odds of 1.8 among those with one type of adverse childhood experience to 7.0 among those with 6-7. CONCLUSIONS: Among individuals with a history of adverse childhood experiences, risky sexual behavior may represent their attempts to achieve intimate interpersonal connections. Having grown up in families unable to provide needed protection, such individuals may be unprepared to protect themselves and may underestimate the risks they take in their attempts to achieve intimacy. If so, coping with such problems represents a serious public health challenge.

The risk of menstrual abnormalities after tubal sterilization. U.S. Collaborative Review of Sterilization Working Group.

BACKGROUND: The existence of a post-tubal-ligation syndrome of menstrual abnormalities has been debated for decades. We used data from the U.S. Collaborative Review of Sterilization to determine whether the likelihood of persistent menstrual abnormalities was greater among women who had undergone tubal sterilization than among women who had not. METHODS: A total of 9514 women who underwent tubal sterilization and 573 women whose partners underwent vasectomy were followed in a multicenter, prospective cohort study for up to five years by means of annual telephone interviews. All women were asked the same questions about six characteristics of their menstrual cycles in the presterilization and follow-up interviews. Multiple logistic-regression analysis was used to assess the risk of persistent menstrual changes. RESULTS: The women who had undergone sterilization were no more likely than those who had not undergone the procedure to report persistent changes in intermenstrual bleeding or the length of the menstrual cycle. They were more likely to have decreases in the number of days of bleeding (odds ratio, 2.4; 95 percent confidence interval, 1.1 to 5.2), the amount of bleeding (odds ratio, 1.5; 95 percent confidence interval, 1.1 to 2.0), and menstrual pain (odds ratio, 1.3; 95 percent confidence interval, 1.0 to 1.8) and to have an increase in cycle irregularity (odds ratio, 1.6; 95 percent confidence interval, 1.1 to 2.3). Among women who had had very heavy bleeding at base line, women who had undergone sterilization were more likely than women who had not undergone the procedure to report decreased bleeding (45 percent vs. 33 percent, P=0.03). CONCLUSIONS: Women who have undergone tubal sterilization are no more likely than other women to have menstrual abnormalities.

Requesting information about and obtaining reversal after tubal sterilization: findings from the U.S. Collaborative Review of Sterilization.

OBJECTIVE: To determine the cumulative probabilities over 14 y of requesting information on sterilization reversal and of obtaining a reversal and to identify risk factors observable at sterilization for both measures of regret. DESIGN: The U.S. Collaborative Review of Sterilization, a prospective cohort study. SETTING: Fifteen medical centers in 9 cities. PATIENT(S): 11,232 women. MAIN OUTCOME MEASURE(S): Cumulative probabilities of requesting information on reversal and undergoing reversal. RESULT(S): The 14-y cumulative probability of requesting reversal information was 14.3% (95% confidence interval [CI], 12.4%-16.3%). Among women aged 18 to 24 y at sterilization, the cumulative probability was 40.4% (95% CI, 31.6%-49.2%). Women aged 18 to 24 y were almost 4 times as likely to request reversal information as were women > or = 30 years of age (adjusted rate ratio [RR], 3.5; 95% CI, 2.8-4.4). Number of living children was not associated with requesting reversal information. The overall cumulative probability of obtaining reversal was 1.1% (95% CI, 0.5-1.6). Younger women (18 to 30 y) were more likely to obtain reversal (RR, 7.6; 95% CI, 3.2-18.3). CONCLUSION(S): Women who were sterilized at a young age had a high chance of later requesting information about reversal, regardless of their number of living children.

Complications of interval laparoscopic tubal sterilization: findings from the United States Collaborative Review of Sterilization.

OBJECTIVE: To estimate the risk of intraoperative or postoperative complications for interval laparoscopic tubal sterilizations. METHODS: We used a prospective, multicenter cohort study of 9475 women who had interval laparoscopic tubal sterilization to calculate the rates of intraoperative or postoperative complications. The relative safety of various methods was assessed by calculating overall complication rates for each major method of tubal occlusion. Method-related complication rates also were calculated and included only complications attributable to a method of occlusion. We used logistic regression to identify independent predictors of one or more complications. RESULTS: When we used a more restrictive definition of unintended major surgery, the overall rate of complications went from 1.6 to 0.9 per 100 procedures. There was one life-threatening event and there were no deaths. Complications rates for each of the four major methods of tubal occlusion ranged from 1.17 to 1.95, with no significant differences between them. When complication rates were calculated, the spring clip method had the lowest method-related complication rate (0.47 per 100 procedures), although it was not significantly different from the others. In adjusted analysis, diabetes mellitus (adjusted odds ratio [OR] 4.5; 95% confidence interval [CI] 2.3, 8.8), general anesthesia (OR 3.2; CI 1.6, 6.6), previous abdominal or pelvic surgery (OR 2.0; CI 1.4, 2.9), and obesity (OR 1.7; CI 1.2, 2.6) were independent predictors of one or more complications. CONCLUSION: Interval laparoscopic sterilization generally is a safe procedure; serious morbidity is rare.

Multiple births and risk of epithelial ovarian cancer.

BACKGROUND AND METHODS: Prevailing hypotheses about the causes of ovarian carcinogenesis predict that women with a history of multiple births (twins, triplets, etc.) should be at increased risk of epithelial ovarian cancer. However, the scant available evidence suggests that they may actually be at lower risk. To resolve this issue, we pooled data from eight studies involving 2859 parous women with epithelial ovarian cancer (case patients) and 7434 parous women without ovarian cancer (control women). In addition to assessing their history of multiple births (and the sex of the children, where available), we obtained information on age, parity, oral contraceptive use, and other reproductive factors for each woman. Details of tumor histology were available for all case patients. We estimated the relative risks of various histologic types of ovarian cancers associated with multiple births by using multivariable logistic regression analysis, adjusting for matching and confounding variables. RESULTS: Among these parous women, 73 case patients (2. 6%) and 257 control women (3.5%) had a history of multiple births. The adjusted summary odds ratio (OR) for developing all types of epithelial ovarian cancer that are associated with multiple births was 0.81 (95% confidence interval [CI] = 0.61-1.08). We found no evidence that risks associated with multiple births differed among women with borderline or invasive tumors and among women with same-sex and opposite-sex offspring from multiple births. The risk reductions appeared specific for nonmucinous tumors (n = 2453; summary adjusted OR = 0.71 [95% CI = 0.52-0.98]); in contrast, associations with mucinous tumors (n = 406) were heterogeneous across studies. CONCLUSIONS: Parous women with nonmucinous ovarian cancer are no more likely to have a history of multiple births than other parous women, counter to the predictions of current hypotheses for causes of ovarian cancer.

Adverse childhood experiences and sexually transmitted diseases in men and women: a retrospective study.

OBJECTIVE: Adverse childhood experiences (ACEs) may have long-term consequences on at-risk behaviors that lead to an increased risk of sexually transmitted diseases (STDs) during adulthood. Therefore, we examined the relationship between ACEs and subsequent STDs for both men and women. METHODS: A total of 9323 (4263 men and 5060 women) adults >/=18 years of age participated in a retrospective cohort study evaluating the association between ACEs and self-reported STDs. Participants were adult members of a managed care organization who underwent routine medical evaluations and completed standardized questionnaires about 7 categories of ACEs, including emotional, physical, or sexual abuse; living with a battered mother; and living with a substance-abusing, mentally ill, or criminal household member. Logistic regression was used to model the association between the cumulative categories of ACEs (range: 0-7) and a history of STDs. RESULTS: We found that 59% (2986) of women and 57% (2464) of men reported 1 or more categories of adverse experiences during childhood. Among those with 0, 1, 2, 3, 4 to 5, and 6 to 7 ACEs, the proportion with STDs was 4.1%, 6.9%, 8.0%, 11.6%, 13.5%, and 20.7% for women and 7.3%, 10.9%, 12.9%, 17.1%, 17.1%, and 39.1% for men. After adjustment for age and race, all odds ratios for reporting an STD had confidence intervals that excluded 1. Among those with 1, 2, 3, 4 to 5, and 6 to 7 ACEs, the odds ratios were 1.45, 1.54, 2.22, 2. 48, and 3.40 for women and 1.46, 1.67, 2.16, 2.07, and 5.3 for men. CONCLUSIONS: We observed a strong graded relationship between ACEs and a self-reported history of STDs among adults.

Cigarette smoking and epithelial ovarian cancer by histologic type.

OBJECTIVE: To examine cigarette smoking as a risk factor for different types of epithelial ovarian cancer. METHODS: We used data from the Cancer and Steroid Hormone Study, a multicenter, population-based, case control investigation. Cases were 447 women aged 20-54 years with diagnoses of epithelial ovarian cancer. Controls were 3868 women selected by random-digit dialing. Conditional logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs) as estimators of the relative risk of ovarian cancer. With age and study site as conditioning variables, OR point estimates were additionally adjusted for parity and use of oral contraceptives. RESULTS: The OR of mucinous epithelial ovarian cancer for women who had ever smoked was 2.3 (95% CI 1.4, 3.9) and for current smokers was 2.9 (95% CI 1.7, 4.9). The OR of mucinous tumors for current smokers was significantly elevated regardless of years since first cigarette or age at which women first smoked. The OR of mucinous tumors for current smokers increased slightly as cumulative pack-years of smoking increased, although the trend was not significant. Similar patterns of elevated risk were not observed among serous, endometrioid, or other histologic types. Odds ratio point estimates for former smokers were not significantly elevated for any histologic type. CONCLUSION: Current cigarette smoking was a risk factor for mucinous epithelial ovarian cancer, but not other histologic types.

Prognostic factors in early-onset epithelial ovarian cancer: a population-based study.

OBJECTIVE: To investigate the clinical prognostic factors that influence ovarian cancer survival in women with early-onset epithelial ovarian cancer using population-based data. METHODS: Subjects in the current study were from a population-based series of 197 patients with invasive ovarian cancer and 60 patients with ovarian cancer of low malignant potential who were identified from the Cancer and Steroid Hormone study. All subjects were between 20 and 54 years of age at diagnosis for ovarian cancer. Epidemiologic data were obtained from each participant. Immunohistochemical staining was performed to assess p53 expression in paraffin-embedded ovarian cancers. Univariate and multivariate analyses for survival were conducted using the proportional hazards model to test the prognostic significance of several clinicopathologic factors among subjects. RESULTS: Among women with invasive tumors, the proportional hazards model revealed that advanced stage at diagnosis [hazard ratio = 4.1, 95% confidence interval (CI) = 2.5, 6.6], age at diagnosis 46-54 (hazard ratio = 2.0, 95% CI = 1.3, 3.0), and overexpression of p53 (hazard ratio = 1.5, 95% CI = 1.1, 2.3) were significantly associated with decreased survival. CONCLUSION: These results provide evidence that stage, age, and p53 overexpression are independent predictors of decreased survival in women with invasive ovarian cancer diagnosed younger than age 55. Further investigation of the effect of age at diagnosis on the relationship between p53 overexpression and ovarian cancer survival is warranted.

Pregnancy recency and risk of ovarian cancer.

OBJECTIVE: A recent analysis suggested that ovarian cancer risk increased with time since last birth, possibly because of some aspect of pregnancy that affects the clearance of cells that have undergone malignant transformation. We analyzed data from four case-control studies pertaining to ovarian cancer risk in relation to age at first pregnancy, age at last pregnancy, and years since last pregnancy: 628 cases and 3432 neighborhood or population controls, ages 18-79, were included. METHODS: We used logistic regression to analyze associations between ovarian cancer risk, controlling for study, age (at diagnosis or corresponding reference age for controls), race, parity, oral contraceptive use, tubal ligation, family history of ovarian or breast cancer, and excluding women with a history of infertility. RESULTS: An early age at first pregnancy was associated with an increased risk of ovarian cancer (odds ratio 1.4, 95% confidence interval (1.1-1.8) for ages < or =19 compared to > or =25). Years since last pregnancy was also associated with increased ovarian cancer risk, with odds ratios of 1.4, 1.4, 1.8, and 2.1 for 10-14, 15-19, 20-24, and > or =25 years compared to 0-9 years (trend test p = 0.004), respectively. CONCLUSION: These observations support the results from the previous study, and raise additional questions about the role of pregnancy in the etiology of ovarian cancer.

Poststerilization regret: findings from the United States Collaborative Review of Sterilization.

OBJECTIVE: To evaluate the cumulative probability of regret after tubal sterilization, and to identify risk factors for regret that are identifiable before sterilization. METHODS: We used a prospective, multicenter cohort study to evaluate the cumulative probability of regret within 14 years after tubal sterilization. Participants included 11,232 women aged 18-44 years who had tubal sterilizations between 1978 and 1987. Actuarial life tables and Cox proportional hazards models were used to identify those groups at greatest risk of experiencing regret. RESULTS: The cumulative probability of expressing regret during a follow-up interview within 14 years after tubal sterilization was 20.3% for women aged 30 or younger at the time of sterilization and 5.9% for women over age 30 at sterilization (adjusted relative risk [RR] 1.9; 95% confidence interval [CI] 1.6, 2.3). For the former group, the cumulative probability of regret was similar for women sterilized during the postpartum period (after cesarean, 20.3%, 95% CI 14.5, 26.0; after vaginal delivery, 23.7%, 95% CI 17.6, 29.8) and for women sterilized within 1 year after the birth of their youngest child (22.3%, 95% CI 16.4, 28.2). For women aged 30 or younger at sterilization, the cumulative probability of regret decreased as time since the birth of the youngest child increased (2-3 years, 16.2%, 95% CI 11.4, 21.0; 4-7 years, 11.3%, 95% CI 7.8, 14.8; 8 or more years, 8.3%, 95% CI 5.1, 11.4) and was lowest among women who had no previous births (6.3%, 95% CI 3.1, 9.4). CONCLUSION: Although most women expressed no regret after tubal sterilization, women 30 years of age and younger at the time of sterilization had an increased probability of expressing regret during follow-up interviews within 14 years after the procedure.

Visits to emergency departments for gynecologic disorders in the United States, 1992-1994.

OBJECTIVE: To assess rates of visits to emergency departments for gynecologic disorders among women of reproductive age in the United States. METHODS: Data from the National Hospital Ambulatory Medical Care Survey for 1992-1994 were analyzed to determine rates of visits to emergency departments among women, ages 15-44 years. Average annual rates per 1000 women were calculated using age, race, and region-specific population estimates. Rate ratios were used to compare rates among subgroups. RESULTS: Approximately 1.4 million gynecologic visits were made to emergency departments annually, for an average annual rate of 24.3 visits per 1000 women, ages 15-44 years (95% confidence interval [CI] 22.0, 26.6). The most frequent diagnoses were pelvic inflammatory disease (average annual rate 5.8, 95% CI 5.0, 6.6), lower genital tract infections including sexually transmitted diseases (average annual rate 5.7, 95% CI 4.8, 6.6), and menstrual disorders (average annual rate 2.9, 95% CI 2.3, 3.5). Nearly half of all gynecologic visits resulted in diagnoses of genital tract infections. Younger women (ages 15-24 years) were 2.3 (95% CI 2.0, 2.6) times as likely as older women (ages 25-44 years), and black women were 3.6 (95% CI 2.9, 4.3) times as likely as white women, to visit emergency departments for gynecologic disorders. Rate ratios for genital tract infections were 10-20 times higher for younger black women than for older, white women. CONCLUSION: Almost half of gynecologic visits to emergency departments were related to genital tract infections, which largely are preventable.

Severity of pelvic inflammatory disease as a predictor of the probability of live birth.

OBJECTIVE: Our aim was to study the association between severity of pelvic inflammatory disease at laparoscopy and the probability of achieving a live birth, while accounting for subsequent episodes of pelvic inflammatory disease. STUDY DESIGN: Beginning in 1960 a cohort of 1288 women in Lund, Sweden, who had clinical symptoms of acute pelvic inflammatory disease and who desired pregnancy was followed for up to 24 years. All participants underwent laparoscopy and were categorized by degree of salpingitis: mild (n = 371), moderate (n = 580), or severe (n = 337) pelvic inflammatory disease. Cumulative live birth rates, obtained by life-table analysis, and proportional hazards ratios were compared among women by severity of pelvic inflammatory disease, while accounting for subsequent episodes. RESULTS: The cumulative proportion of women achieving a live birth after 12 years was 90% for women with mild, 82% for women with moderate, and 57% for women with severe pelvic inflammatory disease. The occurrence of subsequent episodes in women with mild pelvic inflammatory disease did not diminish their long-term probability of live birth, whereas it significantly lowered the probability of live birth in women with severe pelvic inflammatory disease. Women with severe disease and subsequent episodes were eight times more likely to fail to achieve live birth compared with women with a single pelvic inflammatory disease episode with mild disease (relative risk 8.1; 95% confidence interval 3.0 to 22.2). CONCLUSIONS: Increasing severity of pelvic inflammatory disease correlates with a lower long-term probability of live birth. Subsequent episodes have a greater impact on women with severe pelvic inflammatory disease at the index episode compared with those with milder disease.

Increased risk for familial ovarian cancer among Jewish women: a population-based case-control study.

Jewish women have been reported to have a higher risk for familial breast cancer than non-Jewish women and to be more likely to carry mutations in breast cancer genes such as BRCA1. Because BRCA1 mutations also increase women's risk for ovarian cancer, we asked whether Jewish women are at higher risk for familial ovarian cancer than non-Jewish women. To determine the effects of 1) Jewish religion and 2) ovarian cancer in a first-degree relative on women's risk for epithelial ovarian cancer, we used data from a population-based, case-control study conducted in 8 geographic regions in the United States from 1980 through 1982. The study group included 471 cases and 4,025 controls. Jewish women were more likely to have familial ovarian cancer than non-Jewish women [odds ratio (OR) = 8.4, 95% confidence interval (CI) = 2.6-28]. The risk of having ovarian cancer appeared to be greater in Jewish women having a first-degree relative with ovarian cancer (OR = 8.81, 95% CI = 2.02-38.23) than in non-Jewish women having a first-degree relative with ovarian cancer (OR = 3.01, 95% CI = 1.61-5.64), but differences between Jewish and non-Jewish women were not statistically significant. Jewish women with no first-degree relative with ovarian cancer had no increased risk for ovarian cancer (OR = 1.27, 95% CI = 0.74-2.91) compared to non-Jewish women. These results suggest that Jewish women may have a higher rate of familial ovarian cancer than non-Jewish women, but because the results are based on a small number of Jewish women with familial ovarian cancer, the results need to be confirmed in larger studies.

Higher hysterectomy risk for sterilized than nonsterilized women: findings from the U.S. Collaborative Review of Sterilization. The U.S. Collaborative Review of Sterilization Working Group.

OBJECTIVE: To compare the risk of hysterectomy among previously sterilized women and women whose husbands had undergone vasectomy, and to evaluate whether this risk differed by age at surgical procedure or by method of tubal occlusion. METHODS: Our study population comprised 7718 women enrolled in a prospective, multicenter cohort study between 1978 and 1986. After stratifying by the woman's age at surgical procedure, we used the life-table approach and adjusted hazards ratios to examine whether the relative risk of hysterectomy during the 5 years after enrollment differed between the 7174 women who had been sterilized and the 544 women whose husbands had undergone vasectomy. RESULTS: The 5-year cumulative probability of hysterectomy was 8% among the previously sterilized women and 2% among the women whose husbands had undergone vasectomy. Among women 34 years of age and younger at enrollment, sterilized women were 4.4 times as likely to have a hysterectomy as women whose husbands had undergone vasectomy (95% confidence interval [CI] 1.9, 10.0). Findings were similar for women 35 years of age and older (rate ratio = 4.6; 95% CI 1.4, 14.5). Each of the six most commonly used methods of tubal occlusion was associated with an increased risk of hysterectomy. CONCLUSION: Women undergoing tubal sterilization were more likely than women whose husbands underwent vasectomy to undergo hysterectomy within 5 years after sterilization, regardless of age at sterilization. An increased risk of hysterectomy was observed for each method of tubal occlusion.

Hysterectomy surveillance--United States, 1980-1993.

PROBLEM/CONDITION: In the United States, approximately 600,000 hysterectomies are performed each year, and the procedure is the second most frequently performed major surgical procedure among reproductive-aged women. REPORTING PERIOD COVERED: 1980-1993. DESCRIPTION OF SYSTEM: This surveillance system uses data obtained from CDC's National Hospital Discharge Survey (NHDS) to describe the epidemiology of hysterectomy. The NHDS is an annual probability sample of discharges from non-Federal, short-stay hospitals in the United States. RESULTS: In the United States during 1980-1993, an estimated 8.6 million women aged > or =15 years had a hysterectomy. The overall rate of hysterectomy declined slightly from 1980 (7.1 hysterectomies per 1,000 women) to 1987 (6.6 per 1,000 women). The redesign of the NHDS in 1988 resulted in a decrease in estimated rates (i.e., the average annual rate for 1988-1993 was 5.5 per 1,000 women). Rates differed by age, with women aged 40-44 years most likely to have this procedure. Overall annual rates of hysterectomy did not differ significantly by race. The diagnosis most often associated with hysterectomy was uterine leiomyoma; during 1988-1993, this diagnosis accounted for 62% of hysterectomies among black women, 29% among white women, and 45% among women of other races. During 1988-1993, the percentage of hysterectomies performed by the vaginal route increased significantly; furthermore, an increasingly higher percentage of vaginal hysterectomies were accompanied by bilateral oophorectomy. From 1991 through 1993, laparoscopy was associated more frequently with vaginal hysterectomy than in previous years. INTERPRETATION: The rate of hysterectomy decreased slightly during the first half of the 14-year surveillance period, then leveled off during the second half. The increase in simultaneous coding of laparoscopy and vaginal hysterectomy on hospital discharge forms probably reflected the growing use of laparoscopically assisted vaginal hysterectomy. ACTIONS TAKEN: Continued surveillance for hysterectomy will enable changes in clinical practice (e.g., the use of LAVH) to be identified, and information derived from the surveillance system may assist in directing biomedical assessment priorities (e.g., to determine the reasons for race-specific differences in the prevalence of uterine leiomyoma).
