THE INCIDENCE OF PELVIC ENDOMETRIOSIS IN ROCHESTER, MINNESOTA, 1970-1979

The primary objectives of the study were to measure the incidence of pelvic endometriosis among white females of reproductive age (15-49 years) in Rochester, Minnesota, during the period 1970-1979 and to determine the risk of endometriosis by age, marital status, nun status, and educational attainment in this population. An historical prospective design was used. Incident (newly diagnosed) cases were identified from community medical records, and person-years of risk in the study population were estimated from census data.^ Almost two-thirds of the incident cases had surgically verified endometriosis, while the remainder were diagnosed by clinical findings alone. Incidence rates were prepared first with histologically confirmed cases only and then with the successive inclusion of less certain cases: surgically visualized, clinically probable, and clinically possible. On this basis, overall incidence rates were 108.8 to 246.9 newly diagnosed cases per 100,000 person-years. The incidence of pelvic endometriosis was lowest for women 15-19 years of age, increased markedly through age 44, and then declined for women 45-49 years of age. A significantly greater risk of pelvic endometriosis in never married women was detected only when the numerator was limited to histologically confirmed cases. Among never married women 20-49 years of age, no significant difference in the risk of pelvic endometriosis by nun status was detected, but a trend toward a lower incidence in nuns was observed. Women with education beyond high school had a significantly higher incidence of endometriosis than women with less education.^ Cases in the four diagnostic groups differed greatly by age and marital status but were similar with respect to virtually all other characteristics, once age differences were considered. Reproductive history characteristics described included: age of menarche; history of menopause; total pregnancies; ages of first pregnancy, marriage, and sexual intercourse; years from menarche to first intercourse; years of ovulatory cycling; difficulty becoming pregnant; and delay of the first pregnancy by choice. How these characteristics of incident cases differ from those of women free of endometriosis needs to be studied in future research. ^

A CASE-CONTROL STUDY OF RISK FACTORS FOR ECTOPIC PREGNANCY (ROCHESTER, MINNESOTA, OBSTETRICS)

A population-based case-control study of risk factors for ectopic pregnancy has been conducted. The investigation includes 274 cases diagnosed in Rochester, Minnesota residents from 1935 through 1982, and 548 matched controls selected from live birth deliveries. Risk factor information documented prior to the last index menstrual period was obtained via medical record abstract for 22 potential risk factor variables.^ Univariate matched analyses revealed nine variables with significantly elevated odds ratios (ORs). Following conditional logistic regression for matched sets, four variables remained as significant risk factors for ectopic pregnancy. These risk factors with ORs and 95% confidence intervals (Cls) were: current intrauterine device use (OR = 13.7, Cl = 1.6 - 120.6), infertility (OR = 2.6, Cl = 1.6 - 4.2), pelvic inflammatory disease (OR = 3.3, Cl = 1.6 - 6.6), and tubal surgery (OR = 4.5, Cl = 1.5 - 13.9). After adjusting for these four major risk factors, the following variables did not have statistically significant ORs: abdominal/pelvic surgery (OR = 2.0), acute appendicitis (OR = 2.0), anovulation (OR = 1.2), clomiphene citrate use during the index conception (OR = 3.5), induced abortion (OR = 2.1), in utero exposure to diethylstilbestrol (OR = 1.6), myomas (OR = 0.7), ovarian cysts (OR = 1.0), and past intrauterine device use (OR = 1.2). ^

MEETING THE NEEDS OF HANDICAPPED CHILDREN: A STUDY OF EDUCATIONAL AND HEALTH CARE SERVICES PROVIDED TO PRE-KINDERGARTEN CHILDREN IN THE HOUSTON INDEPENDENT SCHOOL DISTRICT EARLY CHILDHOOD PROGRAM FOR THE HANDICAPPED (PARENT SATISFACTION, FUNCTIONAL STATUS, PSYCHOSOCIAL DEVELOPMENT)

The Education for All Handicapped Children Act of 1975, P.L. 94-142, created a new challenge for the nation's public school systems. During 1982-1983, a national study, called the "Collaborative Study of Children with Special Needs", was conducted in 5 metropolitan school districts to evaluate the effectiveness of education and health care services of children in kindergarten to 6th grade being provided under P.L. 94-142 programs. This dissertation (the Substudy) was undertaken to augment the findings of the Collaborative Study. The purpose of this study was to develop a database to provide descriptive information on the demographic, service and health characteristics of a small group of 3 and 4 year old handicapped children served by the Houston Independent School District (HISD) during 1982-1983.^ The study involved a stratified sample of 105 three and four year old children divided into 3 groups according to type of handicapping condition.^ The results of the study gave a clearer picture of the demographic characteristics of these Pre-K children. Specifically, sex ratio was approximately one, lower than the national norm. Family and socioeconomic characteristics were assessed.^ The study used an independence/dependence index composed of 11 items on the parent questionnaire to assess the level of functional independence of each child. An association was found between index scores and parent-reported effects of the child on family activity. Parents who said that their child's condition had affected the family's job situation, housing accomodations, vacation plans, marriage, choice of friends and social activities were also more likely to report less independence in the child. In addition, many of the Substudy children had extensive care-taking needs reflected in specific components of the index such as dressing, feeding, toileting or moving about the house.^ In general the results of the Pre-K Substudy indicate that at the early childhood level, the HISD special education program is functioning well in most areas and that parents are very satisfied with the program.

A PUBLIC HEALTH SURVEILLANCE SYSTEM FOR THE WESTERN CAYO DISTRICT, BELIZE (DISEASE)

A demonstration project entailing disease surveillance was conducted in the western Cayo District, Belize, from November 1981 to March 1982. The purpose was to test and demonstrate the feasibility of community-based surveillance. Interviews were conducted in three hundred twenty households at monthly intervals over a five-month period. Information regarding disease prevalence and medical care utilization relevant to public health practice was analyzed by staff attached to the health center in Benque Viejo. Data collected at the health center were used to validate reported findings.^ Differences between reported and actual study findings regarding clinic visits were small, though in many instances statistically significant. The proportion of underreported clinic visits was greater than the proportion overreported. Overall, reporting accuracy improved with time, particularly from the first to second month. Clinic utilization experience reported for men was as accurate as that reported for females.^ There was agreement between interview and clinic disease findings. In fact, the proportion of conditions defined in the interview and matched to clinic findings was high (malaria, diarrhea, dysentery, skin sores and ulcerations, and problems of nutrition) except for upper respiratory disorders. Finally, some conditions were more likely to be taken to the health center than others, e.g., children with diarrhea or skin sores and ulcerations were less likely to be taken to the health center than if they had malaria. ^

Improving pregnancy prevention in the Austin Independent School District: Student participation in the development of social marketing media

Pregnancy prevention is an important goal of the Austin Independent School District (AISD), but present activity is limited to utilizing a single curriculum. To effectively prevent pregnancy, a diverse range of programs and activities is needed—including media and social marketing. This project (1) reviews literature to identify best practices and characteristics of effective pregnancy prevention programs for AISD, (2) reports on the results of meetings that gathered recommendations for effective channels and media messages for pregnancy prevention among high school students in Central Texas, and (3) presents samples of social marketing media products developed for pregnancy prevention that can be used by AISD.^

Hospital district viability and Medicaid /market changes

Hospital districts (HD) that serve the uninsured and the needy face new challenges with the implementation of Medicaid managed. The potential loss of Medicaid patients and revenues may affect the ability to cost-shift and subsequently decrease the ability of the HD to meet its legal obligation of providing care for the uninsured. ^ To investigate HD viability in the current market, the aims of this study were to: (1) describe HD's environment, (2) document the HDs strategic response, (3) document changes in the HD's performance (patient volume) and financial status, and (4) determine whether relationships or trends exist between HD strategy, performance and financial status. ^ To achieve these aims, three Texas HDs (Fort Worth, Lubbock, and San Antonio) were selected to be evaluated. For each HD four types of strategic responses were documented and evaluated for change. In addition, the ability of each HD to sustain operations was evaluated by documenting performance and financial status changes (patient volume and financial ratios). A pre-post case study design method was used in which the Medicaid managed care “rollout'” date, at each site, was the central date. First, a descriptive analysis was performed which documented the environment, strategy, financial status, and patient volume of each hospital district. Second, to compare hospital districts, each hospital district was: (i) classified by a risk index, (ii) classified by its strategic response profile, and (iii) given a performance score based upon pre-post changes in patient volume and financial indicators. ^ Results indicated that all three HDs operate in a high risk environment compared to the rest of the nation. Two HDs chose the “Status Quo” response whereas one HD chose the “Competitive Proactive” response. Medicaid patient volume decreased in two of three HDs whereas indigent patient volume increased in two of the three (an indication of increasing financial risk). Total patient revenues for all HDs increased over the study period; however, the rate of increase slowed for all three after the Medicaid rollout date. All HDs experienced a decline in financial status between pre-post periods with the greatest decline observed in the HD that saw the greatest increase in indigent patient volume. ^ The pre-post case study format used and the lack of control study sites do not allow for assignment of causality. However, the results suggest possible adverse effects of Medicaid managed care and the need for a larger study, based on a stronger evaluation research design. ^

(Table 5) Experimental hydrodynamic parameters for different soil types obtained in the Lüchow-Dannenberg district, Lower Saxony

In three typical sandy soils of Northern Germany the mobility of radioactive fission products of technetium, iodine, ruthenium and zirconium have been investigated in dependence of the hydrodynamic and physico-chemical soil properties. The laboratory experiments, which simulated fall-out events, used soil columns (1 m length, 30 cm diameter) taken as undisturbed as possible. By measurements of the breakthrough curves in the percolate and of the depth distribution of radionuclides in the soil columns after 6 months the average transport velocity could be determined. These values could be compared with the average water velocity measured by 3H tagging. Three qualitative mobility relations were observed: Ranker: Tc > Ru > I > Zr; Podsol: Tc > Ru > I > Zr; Brown forest soil: Tc = Ru > I > Zr. Relations between some physico-chemical soil properties and the retardation of radionuclides due to adsorption could be observed (eg. retardation of iodine and technetium by organic substances). The average retardation factors of the radionuclides and the hydrodynamic soil parameters are used in a model which gives a quantitative assessment of the hazard of groundwater contamination by a fall-out event in areas covered with comparable soils.
