Trends in bariatric surgery for morbid obesity in Wisconsin.

BACKGROUND: Obesity is a national epidemic with rates in Wisconsin and the United States doubling over the past decade. Research of available treatments for morbid obesity (body mass index > or = 40 kg/m2) suggests that bariatric surgery may be the only modality that provides any significant long term weight loss. METHODS: Using the data from Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System, we analyzed self-reported information on body weight and height among adults in Wisconsin. We used the WITHIN database for inpatient hospitalization and surgeries in Wisconsin to evaluate trends in gastric bypass surgery. Finally, we surveyed bariatric surgeons in Wisconsin to assess trends in bariatric surgery in the state. RESULTS: In Wisconsin, the percentage of the adults considered to be obese increased from 11% in 1990 to 22% in 2001. In 1999-2001, approximately 80,000 adults (2% of the population) were morbidly obese. The number of gastric bypass surgeries performed in Wisconsin more than doubled in 1 year, from 182 in 2001 to 426 in 2002. According to bariatric surgeons, gastric bypass accounts for approximately 90% of bariatric surgeries performed in Wisconsin. Thus, in 2002, there was roughly 1 bariatric surgery for every 200 morbidly obese Wisconsin adults. Most (84%) bariatric surgeons are planning to increase the number of procedures they perform, and 24% plan on adding an additional bariatric surgeon to their group. SUMMARY: Bariatric surgery rates are increasing in Wisconsin, yet the demand for surgery far exceeds current capacity of surgeons in the state.

Social networks and quality of life among female long-term colorectal cancer survivors.

BACKGROUND: The population of long-term colorectal cancer survivors in the United States continues to increase, but little is known about how they fare-physically, mentally, or socially-in the years after diagnosis. The current study examines female long-term colorectal cancer survivors' health-related quality of life (HRQoL) in relation to social networks. METHODS: A population-based sample of female colorectal cancer survivors (n = 726) residing in Wisconsin was recontacted approximately 9 years after the initial diagnosis. Of 443 women who were alive in 1999, 307 women completed a follow-up questionnaire. Analysis was conducted on 259 participants who completed the Medical Outcomes Study Short Form 36 Health Status Survey and a modified version of Berkman and Syme's Social Network Index. Using multivariate analyses, HRQoL summary scores were tested for associations with individual and composite measures of social networks, including marital/partner status; number of children, relatives, and friends; and the frequency of religious and community participation. RESULTS: After adjusting for age, extent of disease at diagnosis, number of comorbidities, body mass, and education, HRQoL was similar to norms published for the general population. Individual social network measures (including the number of relatives and friends) and composite network measures (including network size, the number of ties seen at least once per month, and overall social connectedness) were associated positively with mental health. CONCLUSIONS: Social networks may have an important relation with HRQoL-particularly mental health-among female long-term colorectal cancer survivors. The results of this study should be of interest to those seeking to understand or improve HRQoL among this growing population.

Geocoding addresses from a large population-based study: lessons learned.

BACKGROUND: Geographic information systems (GIS) and spatial statistics are useful for exploring the relation between geographic location and health. The ultimate usefulness of GIS depends on both completeness and accuracy of geocoding (the process of assigning study participants' residences latitude/longitude coordinates that closely approximate their true locations, also known as address matching). The goal of this project was to develop an iterative geocoding process that would achieve a high match rate in a large population-based health study. METHODS: Data were from a study conducted in Wisconsin using mailing addresses of participants who were interviewed by telephone from 1988 to 1995. We standardized the addresses according to US Postal Service guidelines, used desktop GIS geocoding software and two versions of the Topologically Integrated Geographic Encoding and Referencing street maps, accessed Internet mapping engines for problematic addresses, and recontacted a small number of study participants' households. We also tabulated the project's cost, time commitment, software requirements, and brief notes for each step and their alternatives. RESULTS: Of the 14,804 participants, 97% were ultimately assigned latitude/longitude coordinates corresponding to their respective residences. The remaining 3% were geocoded to their zip code centroid. CONCLUSION: The multiple methods described in this work provide practical information for investigators who are considering the use of GIS in their population health research.

Endometrial cancer incidence in relation to electric blanket use.

Endometrial cancer is associated with endogenous and exogenous estrogen excess. Some investigators have posited that electromagnetic fields may influence cancer risk through estrogenic hormonal mechanisms; however, there have been no studies reporting on electric blanket exposure in relation to endometrial cancer. The authors examined this possible association between endometrial cancer risk and electric blanket or mattress cover use as part of a population-based, case-control study. This analysis included incident endometrial cancer cases 40-79 years of age, interviewed during 1994 (n = 148; response rate, 87%) and identified from the Wisconsin tumor registry. Female controls of similar age were randomly selected from population lists (n = 659; response rate, 85%). Information regarding electric blanket and mattress cover use and endometrial cancer risk factors was obtained through structured telephone interviews approximately 1 year after diagnosis. After adjustment for age, body mass index, and postmenopausal hormone use, the risk of endometrial cancer was similar among ever users (odds ratio = 1.04, 95% confidence interval: 0.70, 1.55) and among current users (odds ratio = 0.87, 95% confidence interval: 0.49, 1.54) as compared with never users. Despite its small size and potential misclassification of exposure, this study provides evidence against an association between electric blanket or mattress cover use and endometrial cancer.

Prevalence and treatment of menopausal symptoms among breast cancer survivors.

Women diagnosed with breast cancer often experience early menopause secondary to treatment effects, yet physicians may be reluctant to prescribe hormone replacement therapy (HRT) because of the potential increased risk of recurrence. To assess the burden of menopausal symptoms, HRT use, and alternative treatments in recent breast cancer survivors, a population-based, case-control study was conducted among breast cancer survivors and age-matched controls. Wisconsin women 18-69 years old with a new diagnosis of breast cancer 8-11 months prior to interview (n = 110) and control subjects randomly selected from population lists (n = 73) responded to a standardized telephone questionnaire that elicited information on menopausal symptoms, estrogen and alternative therapies (prescription medications, vitamins, herbal preparations, soy products, acupuncture, chiropractic) used to alleviate symptoms. We used multivariate logistic regression to obtain odds ratios and 95% confidence intervals (CI) for symptoms of menopause, use of estrogen, and use of alternative therapies. Breast cancer survivors were 5.3 (95% CI 2.7-10.2) times more likely to experience symptoms, 25 (95% CI 8.3-100) times less likely to use estrogen, and 7.4 (95% CI 2.5-21.9) times more likely to use alternatives than controls. Soy, vitamin E, and herbal remedies were the most common alternative therapies reported by participants; use was greater in cases compared to controls. Most soy users reported increasing soy products specifically to reduce the chances of a diagnosis of recurrent breast cancer. Among cases, tamoxifen users (n = 62) reported a higher prevalence of symptoms and a higher prevalence of alternative treatments. This is the first population-based survey of menopausal symptoms and treatments that compares breast cancer cases with disease-free controls. Cases are both more likely to experience menopausal symptoms and less likely to use HRT than controls. Instead, cases treat menopausal symptoms with vitamin E and soy products, even though the safety and efficacy of these therapies are unproven. The increased use of soy products in this population has not been previously documented.

The role of epidemiology in chronic disease prevention and health promotion programs.

Although the role for epidemiology is widely accepted in public health programs in general, its role in chronic disease programs is not as widely recognized. One possible barrier to improving epidemiologic capacity in chronic disease prevention and health promotion programs is that chronic disease program managers and public health decision makers may have a limited understanding of basic chronic disease epidemiology functions. We describe the assessment process of data collection, analysis, interpretation, and dissemination, and, using examples from two states, illustrate how this approach can be used to support program and policy development in three areas: by defining the problem, finding programs that work, and evaluating the effects of the program over time. Given the significant burden of chronic diseases in the United States, the scientific guidance provided by epidemiology is essential to help public health leaders identify priorities and intervene with evidence-based and effective prevention and control programs.

Evaluation of the Centers for Disease Control and Prevention's chronic disease state-based epidemiology for public health program support (STEPPS) program.

To identify effective strategies for improving epidemiology capacity in state chronic disease programs, staff epidemiologists and program directors from 25 states were interviewed using a structured questionnaire by phone or in person. Respondents reported three chief barriers to chronic disease epidemiology capacity: lack of institutional commitment and support for chronic disease epidemiology; lack of professional opportunities to engage with peers, colleagues, and scientists; and lack of trained epidemiology staff and resources to support chronic disease functions and activities. Epidemiology capacity in states would be improved by expanding the role and scope of staff placement programs; assisting states in establishing formal collaborations with academic institutions; and providing technical assistance to staff currently employed in states through training, consultation, and networking.

Tuberculosis cases in Wisconsin: documentation of treatment improvement and completion of treatment, 2000-2002.

OBJECTIVE: In 2000, the Wisconsin Strategic Plan for the Elimination of Tuberculosis (TB) sets goals of 90 percent treatment completion and 95 percent documentation of treatment improvement for all reported cases of TB. This study measures the success in achieving these goals. METHODS: Data were abstracted from charts of all 249 reported TB cases during 2000-2002. Treatment completion was considered for patients indicated for completion in 12 months or less. Documentation of treatment improvement included therapy adherence, sputum culture conversion, and chest radiograph improvement for pulmonary cases, and therapy adherence and clinical improvement for extrapulmonary cases. RESULTS: Treatment completion was measured in 204 of 249 TB cases; 87.1 percent completed treatment in 12 months or less. There was a significant difference in completion by site of disease, 89.9 percent for pulmonary cases and 66.1 percent for extrapulmonary cases (P < .01). Documentation of treatment improvement was 61.2 percent among pulmonary cases and 83.6 percent among extrapulmonary cases (P < .01). During the study period, there was a significant decrease in documentation rates for patients with pulmonary TB (P < .01). CONCLUSIONS: The goal of 90 percent treatment completion was nearly accomplished but the goal of 95 percent documentation of treatment improvement was not achieved. Barriers to TB treatment in Wisconsin need to be identified. Case management of TB is necessary for control and prevention of TB.

Trends in total knee replacement surgeries and implications for public health, 1990-2000.

OBJECTIVES: Total joint replacements are important surgical interventions for treating severe arthritis of weight-bearing joints. The most common indication for total knee replacement (TKR) is osteoarthritis of the knee joint. The goals of this study were to assess the trend in rate of TKR in Wisconsin and to describe the economic impact of these surgical procedures on the health care system. METHOD: A population-based cross-sectional study of TKR surgeries was conducted among Wisconsin residents aged > or = 45 years. The Wisconsin inpatient hospital discharge data from 1990 through 2000 were used. Rates were age-adjusted to the 2000 U.S. population, and charges for TKR were adjusted for inflation. RESULTS: From 1990 through 2000, the age-adjusted rate for TKR increased by 81.5% (from 162 to 294 per 100,000; p<0.001). The rate increased the most among the youngest age group (45-49 years), rate ratio 5.1 for men, 4.2 for women. The total charges for TKR increased from 69.4 million dollars to 148 million dollars (109.2% inflation-adjusted increase). Medicare received the highest proportion of charges for TKR procedures, but throughout the study period, the proportion of charges covered by private insurance increased by 39%. CONCLUSIONS: The rate and costs of TKR procedures among Wisconsin residents increased substantially from 1990 through 2000, especially among younger age groups. Changes in medical practices probably accounted for some of this increase, but these trends also may reflect an increased prevalence of osteoarthritis, which in turn may be related to dramatic increases in the number of individuals who are overweight.
