Risk of malformations associated with residential proximity to hazardous waste sites in Washington State

Hazardous waste sites often contain substances harmful to fetal development. Using linked birth-hospital discharge and hazardous sites data for Washington State, we evaluated the association between malformation occurrence and maternal residential proximity to hazardous waste sites. Cases (N=63,006) were infants born 1987-2001 with malformations. Controls (N=315,030) were randomly selected infants without malformations born during these years. Distance between maternal residence and nearest hazardous waste site was measured using geographic information systems (GIS) software. Odds ratio (OR) estimates of the relative risk of malformation at varying distances were calculated. Relative to living >5 miles from a site, living < or = 5 miles was associated with increased risk of any malformations in offspring (for >2- < or = 5 miles: OR 1.15: 95% Confidence Interval (CI): 1.10, 1.21; for >1- < or = 2 miles: OR 1.26, 95% CI: 1.20, 1.32; for >0.5- < or = 1 miles: OR 1.28, 95% CI: 1.22, 1.35; for < or = 0.5 miles: OR 1.33, 95% CI: 1.27, 1.40.) Risk estimates varied by urban vs. rural maternal residence and by specific malformation type. Hazardous waste sites are often located within populated areas. Thus, the possibility of increased malformation occurrence among those in close proximity deserves closer scrutiny.     

Rurality and Other Determinants of Early Colorectal Cancer Diagnosis in Nebraska: A 6-Year Cancer Registry Study, 1998-2003

ABSTRACT:  Background: There are no studies of rurality, and other determinants of colorectal cancer (CRC) stage at diagnosis with population-based data from the Midwest. Methods: This retrospective study identified, incident CRC patients, aged 19 years and older, from 1998-2003 Nebraska Cancer Registry (NCR) data. Using federal Office of Management and Budget classifications, we grouped patients by residence in metropolitan, micropolitan nonmetropolitan, or rural nonmetropolitan counties (non-core based statistical areas). In univariate and multivariate logistic regression analyses, we examined the association of the county classification and of other determinants with early (in situ/local) versus late (regional/distant) stage at CRC diagnosis. Results: Of the 6,561 CRC patients identified, 45% were from metropolitan counties, 24% from micropolitan nonmetropolitan counties and 31% from rural nonmetropolitan counties, with 32%, 38%, and 33%, respectively, being diagnosed at an early stage. Multivariate analysis showed micropolitan nonmetropolitan residents were significantly more likely than rural nonmetropolitan residents to be diagnosed at an early stage (adjusted OR, 1.22; 95% CI: 1.05-1.42, P < .05). However, rural nonmetropolitan and metropolitan residents did not significantly differ in the likelihood of early diagnosis. Residents with Medicare rather than those with private insurance (P < .0001), married rather than unmarried residents (P < .01), and residents with rectal cancer rather than those with colon cancer (P < .0001) were more likely to be diagnosed at an early stage. Conclusions: Early CRC diagnosis needs to be increased in rural (non-core) non-metropolitan residents, unmarried residents, and those with private insurance.     

Trends in colorectal cancer testing among Medicare subpopulations

BACKGROUND: In 1998, Medicare initiated universal coverage for colorectal cancer (CRC) screening via fecal occult blood testing (FOBT) and sigmoidoscopy. In mid-2001, universal coverage was advanced to screening colonoscopy. This study sought to determine whether trends in CRC testing differed among racial/ethnic, age, or gender subgroups of the Medicare population. METHODS: In 2006, claims from 1995 to 2003 were analyzed for annual 5% random samples of fee-for-service Medicare enrollees living in Surveillance, Epidemiology, and End Results (SEER) regions to calculate the annual, age-standardized percentages of subjects who received FOBT, sigmoidoscopy, or colonoscopy. Logistic regression then modeled trends in annual test use within racial/ethnic, age, and gender subgroups across three Medicare coverage periods (precoverage [1995-1997]; limited coverage [1998-mid-2001]; and full coverage [mid-2001-2003]). RESULTS: The annual use of FOBT and sigmoidoscopy declined from 1995 to 2003 in all racial/ethnic groups, but the relative decline in sigmoidoscopy use was greater among whites compared to nonwhites. In contrast, colonoscopy use increased substantially in all racial/ethnic groups. However, relative to the precoverage period among whites, the full-coverage period was associated with significantly greater colonoscopy use among whites (OR=2.14; 95% CI=2.09, 2.19) than blacks (OR=1.86; 95% CI=1.75, 1.96); Asian/Pacific Islanders (OR=1.73; 95% CI=1.62, 1.86); or Hispanics (OR=1.65; 95% CI=1.49, 1.81). The use of colonoscopy during the full-coverage period was also differentially greater among enrollees aged <80 years. CRC testing trends were similar among male and female enrollees. CONCLUSIONS: Colonoscopy is supplanting sigmoidoscopy as a CRC test among Medicare enrollees, while FOBT use is in decline. The transition from sigmoidoscopy to colonoscopy has occurred more quickly among white than nonwhite Medicare enrollees.     

Impact of distance and facility of initial diagnosis on depression treatment

Objective. To assess whether distance to services or diagnosis at a hospital‐based medical center compared with a community clinic influences the receipt of psychotherapy versus pharmacotherapy for depression. Data Source. Veterans Affairs (VA) administrative data for 132,329 depressed veterans between October 2003 and September 2004. Study Design. Multivariable logistic and multinomial regression models were used to examine the relationship between distance to the nearest mental health facility and the facility of initial depression diagnosis on receipt of any and adequate psychotherapy and/or pharmacotherapy, adjusted for patient characteristics. Principal Findings. Compared with those living within 30 miles of the nearest mental health treatment facility, depressed patients living between 30 and 60 miles away had a decreased likelihood of receiving psychotherapy (OR=0.71; 95 percent CI: 0.66, 0.76) and a greater likelihood of receiving antidepressant treatment (OR=1.27; 95 percent CI: 1.22, 1.33). Initial diagnosis at a small community clinic compared with a VA medical center was not associated with a difference in receipt of any psychotherapy (OR=0.95; 95 percent CI: 0.83, 1.09), but it was associated with decreased likelihood of receiving eight or more psychotherapy visits (OR=0.46; 95 percent CI: 0.35, 0.61) or any antidepressant treatment (OR=0.69; 95 percent CI: 0.63, 0.75). Conclusions. The VA and similar health systems should make efforts to insure adequate psychotherapy is provided to patients who initiate treatment at small community clinics and provide psychotherapy alternatives that may be less sensitive to travel barriers for patients living remote distances from mental health treatment. Extending services to small community clinics that support antidepressant treatment should also be considered.     

Multihospital System Membership and Patient Treatments, Expenditures, and Outcomes

Objective. To determine the relationship between hospital membership in systems and the treatments, expenditures, and outcomes of patients.
Data Sources. The Medicare Provider Analysis and Review dataset, for data on Medicare patients admitted to general medical-surgical hospitals between 1985 and 1998 with a diagnosis of acute myocardial infarction (AMI); the American Hospital Association Annual Survey, for data on hospitals.
Study Design. A multivariate regression analysis. An observation is a fee-for-service Medicare AMI patient admitted to a study hospital. Dependent variables include patient transfers, catheterizations, angioplasties or bypass surgeries, 90-day mortality, and Medicare expenditures. Independent variables include system participation, other admission hospital and patient traits, and hospital and year fixed effects. The five-part system definition incorporates the size and location of the index admission hospital and the size and distance of its partners.
Principal Findings. While the effects of multihospital system membership on patients are in general limited, patients initially admitted to small rural system hospitals that have big partners within 100 miles experience lower mortality rates than patients initially admitted to independent hospitals. Regression results show that to the extent system hospital patients experience differences in treatments and outcomes relative to patients of independent hospitals, these differences remain even after controlling for the admission hospital's capacity to provide cardiac services.
Conclusions. Multihospital system participation may affect AMI patient treatment and outcomes through factors other than cardiac service offerings. Additional investigation into the nature of these factors is warranted.     

Differences in Late‐Stage Diagnosis,Treatment, and Colorectal Cancer‐Related Death Between Rural and Urban African Americans and Whites in Georgia

Purpose: Disparities in health outcomes due to a diagnosis of colorectal cancer (CRC) have been reported for a number of demographic groups. This study was conducted to examine the outcomes of late‐stage diagnosis, treatment, and cancer‐related death according to race and geographic residency status (rural vs urban). Methods: This study utilized cross‐sectional and follow‐up data from the Surveillance, Epidemiology, and End Results (SEER) Program for all incident colon and rectal tumors diagnosed for the Atlanta and Rural Georgia Cancer Registries for the years 1992‐2007. Findings: Compared to whites, African Americans had a 40% increased odds (OR, 1.40; 95% CI, 1.30‐1.51) of late‐stage diagnosis, a 50% decreased odds (OR, 0.50; 95% CI, 0.37‐0.68) of having surgery for colon cancer, and a 67% decreased odds (OR, 0.33; 95% CI, 0.25‐0.44) of receiving surgery for rectal cancer. Rural residence was not associated with late stage at diagnosis or receipt of treatment. African Americans had a slightly increased risk of death from colon cancer (HR, 1.11; 95% CI, 1.00‐1.24) and a larger increased risk of death due to rectal cancer (HR, 1.24; 95% CI, 1.14‐1.35). Rural residents experienced a 15% increased risk of death (HR, 1.15; 95% CI, 1.01‐1.32) due to colon cancer. Conclusions: Further investigations should target African Americans and rural residents to gain insight into the etiologic mechanisms responsible for the poorer CRC outcomes experienced by these 2 segments of the population.     

Residential proximity to industrial facilities and risk of non-Hodgkin lymphoma

Industrial pollution has been suspected as a cause of non-Hodgkin lymphoma (NHL), based on associations with chemical exposures in occupational studies. We conducted a case-control study of NHL in four SEER regions of the United States, in which residential locations of 864 cases and 684 controls during the 10 years before recruitment were used to characterize proximity to industrial facilities reporting chemical releases to the Environmental Protection Agency's Toxics Release Inventory (TRI). For each of 15 types of industry (by 2-digit SIC code), we evaluated the risk of NHL associated with having lived within 2 miles of a facility, the distance to the nearest facility (miles categories of ≤0.5, >0.5-1.0, >1.0-2.0, >2 [referent]), and the duration of residence within 2 miles (years categories of 10, 1-9, 0 [referent]), using logistic regression. Increased risk of NHL was observed in relation to lumber and wood products facilities (SIC 24) for the shortest distance of residential proximity (≤0.5 mile: odds ratio [OR]=2.2, 95% confidence interval [CI]: 0.4-11.8) or the longest duration (10 years: OR=1.9, 95% CI: 0.8-4.8); the association with lumber facilities was more apparent for diffuse large B-cell lymphoma (lived within 2 miles: OR=1.7, 95% CI: 1.0-3.0) than for follicular lymphoma (OR=1.1, 95% CI: 0.5-2.2). We also observed elevated ORs for the chemical (SIC 28, 10 years: OR=1.5, 95% CI: 1.1-2.0), petroleum (SIC 29, 10 years: OR=1.9, 95% CI: 1.0-3.6), rubber/miscellaneous plastics products (SIC 30, ≤0.5 mile: OR=2.7, 95% CI: 1.0-7.4), and primary metal (SIC 33, lived within 2 miles: OR=1.3, 95% CI: 1.0-1.6) industries; however, patterns of risk were inconsistent between distance and duration metrics. This study does not provide strong evidence that living near manufacturing industries increases NHL risk. However, future studies designed to include greater numbers of persons living near specific types of industries, along with fate-transport modeling of chemical releases, would be informative.

The mortality divide in India: the differential contributions of gender, caste, and standard of living across the life course

OBJECTIVES: We investigated the contributions of gender, caste, and standard of living to inequalities in mortality across the life course in India. METHODS: We conducted a multilevel cross-sectional analysis of individual mortality, using the 1998-1999 Indian National Family Health Survey data for 529321 individuals from 26 states. RESULTS: Substantial mortality differentials were observed between the lowest and highest standard-of-living quintiles across all age groups, ranging from an odds ratio (OR) of 4.61 (95% confidence interval [CI]=2.98, 7.13) in the age group 2 to 5 years to an OR of 1.97 (95% CI=1.68, 2.32) in the age group 45 to 64 years. Excess mortality for girls was evident only for the age group 2 to 5 years (OR=1.33, 95% CI=1.13, 1.58). Substantial caste differentials were observed at the beginning and end stages of life. Area variation in mortality is partially a result of the compositional effects of household standard of living and caste. CONCLUSIONS: The mortality burden, across the life course in India, falls disproportionately on economically disadvantaged and lower-caste groups. Residual state-level variation in mortality suggests an underlying ecology to the mortality divide in India.     

Seat belt use among American Indians/Alaska Natives and non-Hispanic whites

BACKGROUND: Accidents (including motor vehicle injuries) are a leading cause of death among American Indians/Alaskan Natives (AI/AN). The purpose of this study was to examine geographic variation and the existence of a seat belt law on seat belt use among AI/AN and non-Hispanic whites (NHW). METHODS: Self-reported seat belt behavior data from the 1997 and 2002 Behavioral Risk Factor Surveillance System were analyzed in 2006-2007 and were restricted to AI/AN (n=4,310 for 2002, and n=1,758 for 1997) and NHW (n=193,617 for 2002, and n=108,551 for 1997) aged 18 years and older. RESULTS: Seat belt non-use varied significantly across geographic regions for both AI/AN and NHW. For example, AI/AN living in the Northern Plains (odds ratio [OR]=12.4, 95% confidence interval [CI]=6.5-23.7) and Alaska (OR=10.3, 95%CI=5.3-19.9) had significantly higher seat belt non-use compared to AI/AN living in the West. In addition, compared to those residing in urban areas, those living in rural areas were 60% more likely in NHW and 2.6 times more likely in AI/AN not to wear a seat belt. Both AI/AN and NHW living in states without primary seat belt laws were approximately twice as likely to report seat belt non-use in 2002 as those living in states with primary laws. In states with primary laws enacted between 1997 and 2002, AI/AN experienced greater decline in seat belt non-use than NHW. CONCLUSIONS: Seat belt use among AI/AN and NHW varied significantly by region and urban-rural residency in 2002. Primary seat belt laws appear to help reduce regional and racial disparities in seat belt non-use.     

Bypassing of Local Hospitals by Rural Medicare Beneficiaries

Several previous studies of hospital utilization by nonelderly rural residents suggest that local rural hospitals have been increasingly bypassed, often for care in urban hospitals. This resulted in lost volume for rural hospitals, detracting from their financial viability. It is not clear to what extent elderly rural residents also bypass local hospitals and whether this reflects regionalization of treatment for some conditions or avoidance of local hospitals assumed to provide inadequate care. This study examines hospital use by aged rural Delaware Medicare beneficiaries living in a ZIP code area that has a local hospital during Fiscal Year (FY) 1987 (N = 670). Most of these Medicare beneficiaries were hospitalized locally. Those beneficiaries who bypassed local rural hospitals usually did so because cardiovascular surgical procedures were required and were often only performed in large urban teaching hospitals. Beneficiaries using nonlocal hospitals were similar to users of local hospitals with respect to age and sex and traveled an average of nearly 42 miles for treatment. "Bypassing" here appears to be due primarily to regional specialization of care rather than abandonment of local rural hospitals by rural residents.     

The Relationship Between Rural Status,Individual Characteristics,and Self‐Rated Health in the Behavioral Risk Factor Surveillance System

Purpose: To examine rural status and social factors as predictors of self‐rated health in community‐dwelling adults in the United States. Methods: This study uses multinomial logistic and cumulative logistic models to evaluate the associations of interest in the 2006 US Behavioral Risk Factor Surveillance System, a cross‐sectional survey of 347,709 noninstitutionalized adults. Findings: Self‐rated health was poorer among rural residents, compared to urban residents (OR = 1.77, 95% CI: 1.54, 1.90). However, underlying risk factors such as obesity, low income, and low educational attainment were found to vary by rural status and account for the observed increased risk (OR = 1.03, 95% CI: 0.94, 1.12). There was little evidence of effect modification by rural status, though the association between obesity and self‐rated health was stronger among urban residents (OR = 2.50, 95% CI: 2.38, 2.64) than among rural residents (OR = 2.18, 95% CI: 2.03, 2.34). Conclusions: Our findings suggest that differences in self‐rated health by rural status were attributable to differential distributions of participant characteristics and not due to differential effects of those characteristics.     

Is home renovation or repair a risk factor for exposure to lead among children residing in New York City?

Children can be lead poisoned when leaded paint is disturbed during home renovation or repair. We conducted a case-control study to assess the association between elevated blood lead levels (BLLs) in children younger than 5 years of age and renovation or repair of homes built before 1950 in New York City. In 1998, we interviewed parents of 106 case children (BLLs)≥10 μg/dL) and 159 control children (BLLs≤5 μg/dL) living in selected New York City neighborhoods. We then used logistic regression methods to estimate odds ratios (ORs) for elevated BLLs among children living in housing that had undergone varous renovations or repairs in the 6 months before the blood lead test, and we adjusted for age and test month. Case children were only slightly more likely than control children to live in a house that had undergone any renovation (OR=1.2, 95% confidence interval [95% CI]=0.7, 2.1). Case children were more likely to (1) live in housing that had interior surfaces prepared for painting, especially by hand sanding (OR=3.5, 95% CI=1.1, 10.9; population attributable risk [PAR%]=10.4%, 95% CI=0.5% 19.3%); and (2) have work-created dust throughout their housing unit (OR =6.3, 95% CI=1.2, 32.3; PAR%=6.8%, 95% CI=0.0%, 13.1%). The risk for excess lead exposure is increased by home renovation or repair work involving interior paint preparation or reported dispersal of dust beyond the work area. The proportion of cases related to this exposure is high enough to merit preventive measures.     

Racial differences in colorectal cancer test use by Medicare consumers

BACKGROUND: Lower use of colorectal cancer (CRC) screening has been suggested as a factor in higher rates of CRC incidence and mortality among African Americans. Racial differences in colorectal cancer test use are not well understood. METHODS: The study sample included respondents aged 50 to 80 to a 2001 telephone survey of Medicare consumers from two states. The analyses, initiated in 2004, were limited to respondents with no history of CRC (n = 1901). Three CRC tests were examined: fecal occult blood tests (FOBTs), sigmoidoscopy, and colonoscopy. Type of testing and testing according to Medicare coverage intervals by race were compared. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained from unadjusted and adjusted models to assess the independent associations between race and test use. RESULTS: Adherence to the Medicare-covered intervals for CRC tests was low (56.8% for whites, 39.1% for African Americans), and did not significantly differ by race after adjustment. African Americans were, however, significantly less likely to have ever been tested (OR = 0.48, 95% CI = 0.33-0.70) and more likely to have had an endoscopic test than an FOBT (OR = 3.06, 95% CI = 1.70-5.51). CONCLUSIONS: The type of test used to screen for colorectal cancer has important implications for compliance with recommended screening intervals. Understanding reasons for racial differences in CRC test use may help identify approaches to increasing test use in the Medicare population.

Does Distance Matter? Distance to Mammography Facilities and Stage at Diagnosis of Breast Cancer in Kentucky

ABSTRACT:  Background: National and regional data indicate that breast cancer early detection is low in Kentucky, especially rural regions, perhaps because access to mammography services can be problematic. Objective: This study examined the distance between residences of women diagnosed with breast cancer and the nearest mammography facility, as a risk factor for advanced stage diagnosis in rural populations. Methods: 1999-2003 Kentucky Cancer Registry data were used for this study. A total of 12,322 women, aged 40 and older at diagnosis, with no previous history of cancer, and with known cancer stage were included. Travel distance was obtained using a geographic information system (GIS). Hierarchical logistic regression models were used to analyze the relationship between travel distance and advanced stage diagnosis. Results: Advanced diagnoses had longer average travel distances than early stage diagnoses (P < 0.01). After adjusting for age, race, insurance, and education at census tract level, the odds of advanced diagnosis were significantly greater for women residing over 15 miles from a facility, compared to those living within 5 miles (adjusted OR = 1.50, 95% CI = 1.25-1.80). Conclusion: Although socioeconomic status, race, and age may help explain advanced diagnoses, longer travel distance also adversely affects early detection for rural populations. Accurate measurement of spatial accessibility indicators, such as travel distance, facilitates identification of at-risk groups so that interventions can be developed to reduce this disease.     

Mortality of Department of Veterans Affairs patients undergoing coronary revascularization in private sector hospitals

OBJECTIVE: A limitation of studies comparing outcomes of Veterans Affairs (VA) and private sector hospitals is uncertainty about the methods of accounting for risk factors in VA populations. This study estimates whether use of VA services is a marker for increased risk by comparing outcomes of VA users and other patients undergoing coronary revascularization in private sector hospitals. DATA SOURCES: Males 67 years and older undergoing coronary artery bypass graft (CABG; n=687,936) surgery or percutaneous coronary intervention (PCI; n=664,124) during 1996-2002 were identified from Medicare administrative data. Patients using VA services during the 2 years preceding the Medicare admission were identified using VA administrative files. STUDY DESIGN: Thirty-, 90-, and 365-day mortality were compared in patients who did and did not use VA services, adjusting for demographic and clinical risk factors using generalized estimating equations and propensity score analysis. RESULTS: Adjusted mortality after CABG was higher (p<.001) in VA users compared with nonusers at 30, 90, and 365 days: odds ratio (OR)=1.07 (95 percent confidence interval [CI], 1.03-1.11), 1.07 (95 percent CI, 1.04-1.10), and 1.09 (95 percent CI, 1.06-1.12), respectively. For PCI, mortality at 30 and 90 days was similar (p>.05) for VA users and nonusers, but was higher at 365 days (OR=1.09; 95 percent CI, 1.06-1.12). The increased risk of death in VA users was limited to patients with service-connected disabilities or low incomes. Odds of death for VA users were slightly lower using samples matched by propensity scores. CONCLUSIONS: A small difference in risk-adjusted outcomes for VA users and nonusers undergoing revascularization in private sector hospitals was found. This difference reflects unmeasured severity in VA users undergoing revascularization in private sector hospitals.     

Colorectal cancer screening participation: comparisons with mammography and prostate-specific antigen screening

OBJECTIVES: The relation of personal characteristics, health and lifestyle behaviors, and cancer screening practices to current colorectal cancer (CRC) screening was assessed and compared with those factors' relation to current mammography screening in women and prostate-specific antigen (PSA) screening in men. METHODS: A cross-sectional random-digit-dialed telephone survey of 954 Massachusetts residents aged 50 and older was conducted. RESULTS: The overall prevalence of current CRC screening was 55.3%. Logistic regression results indicated that family history of CRC (odds ratio [OR] = 1.98; 95% confidence interval [CI] = 1.02, 3.86), receiving a regular medical checkup (OR = 3.07; 95% CI = 2.00, 4.71), current screening by mammography in women and PSA in men (OR = 4.40; 95% CI = 2.94, 6.58), and vitamin supplement use (OR = 1.87; 95% CI = 1.27, 2.77) were significant predictors of CRC screening. CONCLUSIONS: Health and lifestyle behaviors were related to increased current CRC, mammography, and PSA screening. Personal factors independently related to CRC screening were not consistent with those related to mammography and PSA screening. This lack of consistency may reflect different stages of adoption of each type of screening by clinicians and the public.     

Relationship between state medicaid policies, nursing home racial composition, and the risk of hospitalization for black and white residents

OBJECTIVE: To examine racial differences in the risk of hospitalization for nursing home (NH) residents. DATA SOURCES: National NH Minimum Data Set, Medicare claims, and Online Survey Certification and Reporting data from 2000 were merged with independently collected Medicaid policy data. STUDY DESIGN: One hundred and fifty day follow-up of 516,082 long-stay residents. PRINCIPLE FINDINGS: 18.5 percent of white and 24.1 percent of black residents were hospitalized. Residents in NHs with high concentrations of blacks had 20 percent higher odds (95 percent confidence interval [CI]=1.15-1.25) of hospitalization than residents in NHs with no blacks. Ten-dollar increments in Medicaid rates reduced the odds of hospitalization by 4 percent (95 percent CI=0.93-1.00) for white residents and 22 percent (95 percent CI=0.69-0.87) for black residents. CONCLUSIONS: Our findings illustrate the effect of contextual forces on racial disparities in NH care.
