What do physicians in practice do to prevent osteoporosis?

Osteoporosis-associated fractures are a major public health problem in the United States. Although clinicians and policy groups have advocated estrogen replacement therapy and other clinical measures to prevent osteoporosis, few studies have assessed whether these measures are being adopted by physicians in practice. The purpose of this study is to evaluate physicians' use of osteoporosis prevention measures and to assess the impact of physician specialty and practice setting on osteoporosis prevention performance. A survey of nearly 300 physicians was carried out in a large metropolitan area. Gynecologists, general internists, and cardiopulmonary specialists were included from one of three practice settings: fee-for-service private practice, full-time academic medicine, or a large health maintenance organization. Most physicians, regardless of clinical specialty or practice setting, report that they advocate exercise and calcium supplementation. Few physicians prescribe estrogen replacement therapy (ERT) for the majority of their postmenopausal patients. Although there are minimal differences among the three types of practice settings examined, ERT varies markedly by clinical specialty. Of the gynecologists surveyed, 37% report prescribing ERT for the majority of their postmenopausal patients to prevent osteoporosis compared to only 7 and 5% of general internists and cardiopulmonary specialists, respectively (chi 2 = 45.3, p less than 0.0001). Although the efficacy of exercise and calcium supplementation to prevent osteoporotic fractures has not been well established, these measures are commonly advocated by both generalists and subspecialists. Although gynecologists are significantly more likely to prescribe ERT to prevent osteoporosis than the other clinical specialists, in general very few physicians prescribe ERT for most postmenopausal patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Injuries in an elderly inner-city population.

Even though injuries are a leading cause of morbidity and mortality among the elderly in the United States, no comprehensive population-based study of nonfatal and fatal injuries has been carried out in an elderly minority inner-city population. To study injuries in this population, we developed an active surveillance system as part of a large injury prevention program in a poor urban black community. We report 577 cases of nonfatal and fatal injuries in a community of 12,139 persons 65 years of age and older that resulted in emergency room treatment or death between March 1, 1987, and February 29, 1988. Nearly 5% of the elderly population was treated at an emergency room for, or died as a result of, an injury during the study period; the overall injury rate was 48 injuries per 1,000 persons. Injury rates for older women exceeded those for older men and increased with advancing age in both sexes. Fall injuries accounted for 312 (54%) of all injuries and 75% of all hospitalizations for injury. Motor vehicle incidents and violence were the second and third most common injuries, accounting for 13% and 7% of injuries, respectively. Given the predominance of falls relative to other injuries, prevention of falls should receive major emphasis in injury prevention efforts in inner-city minority populations.

Alcohol consumption and outcome of pregnancy.

In a prospective study 1256 pregnant women at their first antenatal visit were asked if they drank alcohol every day, occasionally, or not at all, both at that time and before the diagnosis of pregnancy. There were no significant differences, among the three alcohol groups, in the proportions having miscarriages, perinatal deaths, congenital anomalies, or premature births. Women who reported drinking every day before pregnancy was diagnosed had heavier babies than those who did not drink at all, but there were no differences in mean birth weight according to alcohol use at the first antenatal visit. There were statistically significant differences among the three groups in important background characteristics, such as social class, age, smoking, and marital status. When adjustment was made for these factors, both occasional and daily consumption of alcohol before pregnancy appeared to have significantly positive effects on birth weight. These results illustrate the difficulty of evaluating the effects of alcohol in observational studies, and imply a need for caution in attributing either negative or positive effects of alcohol on the outcome of pregnancy.

Comparison of estrogen-induced hyperplasia to endometrial carcinoma.

Use of exogenous estrogens has been associated with endometrial cancer in a number of case-control studies. This observed association could be biased as a result of frequent misclassification of estrogen-induced hyperplasia as endometrial cancer. To evaluate this possibility, pathology slides from 233 patients with a hospital diagnosis of endometrial cancer were reviewed independently by two pathologists. The hospital diagnosis was confirmed by both pathologists in 86% of the cases, indicating that the misclassification of hyperplasia as carcinoma is uncommon.

Epidemiological pitfalls using Medicaid data in reproductive health research.

The purpose of this report is to discuss methodologic issues in using Medicaid claims data to conduct epidemiologic analyses in reproductive health. We conducted case-control studies that used Medicaid claims data to evaluate two specific reproductive health questions. Case and control pregnancies were selected from among 106,000 women identified in a Medicaid claims file. Medical record review was conducted for randomly selected cases and controls. Several methodological issues were identified. Women could contribute multiple pregnancies that qualified as either case pregnancies, control pregnancies, or both. The results of the medical record review indicated that 25% of one case group (low-birthweight infants) could not be confirmed, and 70% of the second case group (CNS birth defects) were misclassified. Thirty-five percent of women classified as not having undergone diagnostic ultrasonography based on Medicaid claims data had evidence of having received diagnostic ultrasound during pregnancy on the basis of medical record review. Several problems were encountered with the use of Medicaid billing data to address epidemiologic questions in reproductive health. Although solutions to some of these problems could be identified, others could not be addressed without careful review of the medical records. These limitations may not apply to all state Medicaid databases or other claims data, but they should be carefully considered when planning claims-based analyses of reproductive health issues.

Effects of physical activity and life-style factors on uterine contraction frequency.

In this cohort study, uterine contractions were recorded in 81 low-risk pregnant women who wore ambulatory tocodynamometers continuously during three 72-hour periods at advancing gestational ages. During these periods, they also recorded their daily activities in a diary. Examination of the data, in general, revealed no association between uterine contraction frequency and habits such as smoking, alcohol consumption, or drinking caffeinated beverages. Physical activities, such as prolonged standing, heavy housework, lifting, or organized exercise also did not appear to affect uterine contraction rates. Only climbing stairs and walking were associated with increased contraction frequencies, but this effect, although statistically significant, was relatively small in magnitude and was present only during the last gestational age period monitored (30 to 33 weeks).

Hot flashes in the late reproductive years: risk factors for Africa American and Caucasian women.

Hot flashes are a primary reason that midlife women seek medical care, but there is little information about the onset or the predictors of hot flashes in the years before the menopause. This study examines women's experience of hot flashes in the late reproductive years, comparing African American and Caucasian women, and identifies hormonal, behavioral, and environmental risk factors for hot flashes associated with ovarian aging. Data are from a population-based prospective cohort study of ovarian aging in women who were ages 35--47, in general good health, and had regular menstrual cycles at study enrollment. Hot flashes were assessed by subject report in a structured interview at the first follow-up period and correlated highly with previous prospective daily ratings of hot flashes (p = 0.0001). Blood samples were obtained in the first 6 days of the menstrual cycle in two consecutive cycles at enrollment and two consecutive cycles at follow-up. Predictor variables include hormone measures, structured interview, and standard questionnaire data. Thirty-one percent of the sample (n = 375) reported hot flashes (mean age 41 years). In bivariate analysis, more African American than Caucasian women reported hot flashes (38% vs. 25%, p = 0.01). Significant predictors of hot flashes in the final multivariable logistic regression model were higher follicle-stimulating hormone (FSH) levels (odds ratio [OR] 3.19), anxiety (OR 1.06), baseline menopausal symptoms (OR 4.91), alcohol use (OR 1.09), body mass index (BMI) (OR 1.04), and parity (OR 1.20). Race did not predict hot flashes after adjusting for these variables. Hot flashes commonly occur before observable menstrual irregularities in the perimenopause and are associated with both hormonal and behavioral factors. The association of hot flashes with increased body mass (BMI) challenges the current "thin" hypothesis and raises important questions about the role of BMI in hormone dynamics in the late reproductive years.

Symptom reports from a cohort of African American and white women in the late reproductive years.

OBJECTIVE: To identify symptoms experienced in a cohort of healthy women in the late reproductive years; to compare symptom reports between African American and Caucasian women; and to determine the extent to which other factors in reproductive health, mood and behavior, lifestyle, and demographic background are associated with the reported symptoms. DESIGN: A cohort of women aged 35 to 47 years (mean age, 41 years) was identified through random digit dialing. This study is a cross-sectional analysis of data collected at enrollment from a subset of 308 women who completed daily symptom reports (DSR) for one menstrual cycle. Data were obtained in structured interviews and self-administered standard questionnaires. The associations of the study variables with symptoms as assessed by the DSR were examined using analysis of variance and general linear models. RESULTS: The African American women were significantly more likely to report in interview that they experienced menopausal symptoms (46% vs. 30%; p < 0.001) and had significantly higher ratings on the physiological symptom factor of the DSR, which included hot flashes, dizziness, poor coordination/clumsiness, urine leaks, and vaginal dryness. The DSR yielded two other factors of psychological and somatic symptoms. Race was associated only with the physiological symptom factor in the multivariable analyses. Neither race nor age were associated with psychological symptoms, which were predicted by current or past mood problems. CONCLUSIONS: Symptoms commonly associated with the menopause are experienced in the late reproductive years before observable changes in menstrual cycles. African American women reported more physiological symptoms than white women. These data provide an essential baseline for longitudinal study of symptoms associated with the ovarian decline in the perimenopausal years.

Breast cancer screening: effect of physician specialty, practice setting, year of medical school graduation, and sex.

We surveyed physicians of different specialties in a large metropolitan area to determine how their characteristics affected their performance and beliefs about breast cancer screening. Of 664 general internists, obstetrician-gynecologists, and cardiologists surveyed, we received 298 responses (45%). We found significant differences in reported performance of breast cancer screening and physicians' beliefs about mammography screening among practicing obstetrician-gynecologists, internists, and cardiopulmonary specialists. Cardiopulmonary specialists performed the fewest breast examinations and screening mammograms and were most likely to believe annual mammography screening unnecessary even for women in their 50s. We observed no difference between physicians graduating before 1960 and those graduating afterward and no differences according to physician sex. We found similar screening practices and beliefs in the three types of practice settings examined: community-based, private practices, a large health maintenance organization (HMO), and academic medical centers. Obstetrician-gynecologists and internists differed only in the frequency with which they performed breast examinations. Physicians graduating before 1960 in these two groups reported somewhat poorer performance and knowledge of breast cancer screening than those graduating more recently. A majority of all respondents disagreed with American Cancer Society guidelines for mammography screening. Physicians of all specialties reported performing far more breast examinations than screening mammograms on women of all ages, even for those 50-59 years of age. We conclude that all physicians need to improve their screening rates. However, intervention programs should first target those physicians with the greatest deficiencies in breast cancer screening performance and knowledge; these include medical specialists and older physicians in primary care specialties.
