Unmet Healthcare Need Due To Cost Concerns Among U.S. Transgender And Gender-Expansive Adults: Results From A National Survey, Luisa Kcomt, Kevin M. Gorey, Betty Jo Barrett, Dana S. Levin, Jill Grant, Sean Esteban Mccabe

Social Work Publications

This study examines past-year unmet healthcare need due to cost experienced by transgender and gender-expansive (TGE) adults in the United States in the context of the Patient Protection and Affordable Care Act (ACA). It also aims to estimate the importance of having health insurance among TGE Americans (transgender men, transgender women, nonbinary/genderqueer people, and cross-dressers). Data were from the 2015 U.S. Transgender Survey (N ¼ 19,157 adults, aged 25 to 64 years). Multivariable logistic regression models were used to determine the adjusted odds ratios (AOR) and 95 percent confidence intervals (CI) of TGE individuals’ past-year unmet healthcare need due to …

Colon Cancer Care Of Hispanic People In California: Paradoxical Barrio Protections Seem Greatest Among Vulnerable Populations, Keren M. Escobar, Mollie Sivaram, Kevin M. Gorey, Isaac N. Luginaah, Sindu M. Kanjeekal, Frances C. Wright

Social Work Publications

Background: We examined paradoxical and barrio advantaging effects on cancer care among socioeconomically vulnerable Hispanic people in California. Methods: We secondarily analyzed a colon cancer cohort of 3,877 non-Hispanic white (NHW) and 735 Hispanic people treated between 1995 and 2005. A third of the cohort was selected from high poverty neighborhoods. Hispanic enclaves and Mexican American (MA) barrios were neighborhoods where 40% or more of the residents were Hispanic or MA. Key analyses were restricted to high poverty neighborhoods. Results: Hispanic people were more likely to receive chemotherapy (RR=1.18), especially men in Hispanic enclaves (RR=1.33) who were also advantaged on …


Care Of Acute Conditions And Chronic Diseases In Canada And The United States: Rapid Systematic Review And Meta-Analysis, Keren M. Escobar, Dorian Murariu, Sharon Munro, Kevin M. Gorey Jan 2019

Care Of Acute Conditions And Chronic Diseases In Canada And The United States: Rapid Systematic Review And Meta-Analysis, Keren M. Escobar, Dorian Murariu, Sharon Munro, Kevin M. Gorey

Social Work Publications

This study tested the hypothesis that socioeconomically vulnerable Canadians with diverse acute conditions or chronic diseases have health care access and survival advantages over their counterparts in the USA. A rapid systematic review retrieved 25 studies (34 independent cohorts) published between 2003 and 2018. They were synthesized with a streamlined meta-analysis. Very low-income Canadian patients were consistently and highly advantaged in terms of health care access and survival compared with their counterparts in the USA who lived in poverty and/or were uninsured or underinsured. In aggregate and controlling for specific conditions or diseases and typically 4 to 9 comorbid factors …


Multiplicative Advantages Of Hispanic Men Living In Hispanic Enclaves: Intersectionality In Colon Cancer Care: A Research Note, Keren M. Escobar, Mollie Sivaram, Kevin M. Gorey Jan 2019

Multiplicative Advantages Of Hispanic Men Living In Hispanic Enclaves: Intersectionality In Colon Cancer Care: A Research Note, Keren M. Escobar, Mollie Sivaram, Kevin M. Gorey

Social Work Publications

We examined Hispanic enclave paradoxical effects on cancer care among socioeconomically vulnerable people in pre-Obamacare California. We conducted a secondary analysis of a historical cohort of 511 Hispanic and 1,753 non-Hispanic white people with colon cancer. Hispanic enclaves were neighborhoods where 40% or more of the residents were Hispanic, mostly first-generation Mexican American immigrants. An interaction of ethnicity, gender, and Hispanic enclave status was observed such that the protective effects of living in a Hispanic enclave were larger for Hispanic men, particularly married Hispanic men, than women. Risks were also exposed among other study groups: the poor, the inadequately insured, …


Breast Cancer Care In California And Ontario: Primary Care Protections Greatest Among The Most Socioeconomically Vulnerable Women Living In The Most Underserved Places, Kevin M. Gorey, Caroline Hamm, Isaac N. Luginaah, Guangyong Zou, Eric J. Holowaty Jan 2017

Breast Cancer Care In California And Ontario: Primary Care Protections Greatest Among The Most Socioeconomically Vulnerable Women Living In The Most Underserved Places, Kevin M. Gorey, Caroline Hamm, Isaac N. Luginaah, Guangyong Zou, Eric J. Holowaty

Social Work Publications

Background: Better health care among Canada’s socioeconomically vulnerable versus America’s has not been fully explained. We examined the effects of poverty, health insurance and the supply of primary care physicians on breast cancer care. Methods: We analyzed breast cancer data in Ontario (n = 950) and California (n = 6300) between 1996 and 2000 and followed until 2014. We obtained socioeconomic data from censuses, oversampling the poor. We obtained data on the supply of physicians, primary care and specialists. The optimal care criterion was being diagnosed early with node negative disease and received breast conserving surgery followed by adjuvant radiation …


Profound Barriers To Basic Cancer Care Most Notably Experienced By Uninsured Women: Historical Note On The Present Policy Considerations, Amy M. Alberton, Kevin M. Gorey Jan 2017

Profound Barriers To Basic Cancer Care Most Notably Experienced By Uninsured Women: Historical Note On The Present Policy Considerations, Amy M. Alberton, Kevin M. Gorey

Social Work Publications

America is considering the replacement of Obamacare with Trumpcare. This historical cohort revisited pre-Obamacare colon cancer care among people living in poverty in California (N = 5,776). It affirmed a gender by health insurance hypothesis on nonreceipt of surgery such that uninsured women were at greater risk than uninsured men. Uninsured women were three times as likely as insured women to be denied access to such basic care. Similar men were two times as likely. America is bound to repeat such profound health care inequities if Obamacare is repealed. Instead, Obamacare ought to be retained and strengthened in all states, …


Palliative Chemotherapy Among People Living In Poverty With Metastasised Colon Cancer: Facilitation By Primary Care And Health Insurance, Kevin M. Gorey, Emma Bartfay, Sindu M. Kanjeekal, Frances C.

Palliative Chemotherapy Among People Living In Poverty With Metastasised Colon Cancer: Facilitation By Primary Care And Health Insurance, Kevin M. Gorey, Emma Bartfay, Sindu M. Kanjeekal, Frances C. Wright, Caroline Hamm, Isaac N. Luginaah, Guangyong Zou, Eric J. Holowaty, Nancy L. Richter, Madhan K. Balagurusamy

Social Work Publications

Background: Many Americans with metastasised colon cancer do not receive indicated palliative chemotherapy. We examined the effects of health insurance and physician supplies on such chemotherapy in California.

Methods: We analysed registry data for 1199 people with metastasised colon cancer diagnosed between 1996 and 2000 and followed for 1 year. We obtained data on health insurance, census tract-based socioeconomic status and county-level physician supplies. Poor neighbourhoods were oversampled and the criterion was receipt of chemotherapy. Effects were described with rate ratios (RR) and tested with logistic regression models.

Results: Palliative chemotherapy was received by less than half of the participants …

Disparities Among Minority Women With Breast Cancer Living In Impoverished Areas Of California, Sundus Haji-Jama, Kevin M. Gorey, Isaac N. Luginaah, Guangyong Zou, Caroline Hamm, Eric J. Holowaty

Social Work Publications

Background: Interaction effects of poverty and health care insurance coverage on overall survival rates of breast cancer among women of color and non-Hispanic white women were explored. Methods: We analyzed California registry data for 2,024 women of color (black, Hispanic, Asian, Pacific Islander, American Indian, or other ethnicity) and 4,276 non-Hispanic white women (Anglo-European ancestries and no Hispanic-Latin ethnic backgrounds) diagnosed with breast cancer between the years 1996 and 2000 who were then followed until 2011. The 2000 US census categorized rates of neighborhood poverty. Health care insurance coverage was either private, Medicare, Medicaid, or none. Cox regression was used …


Gender Differences On The Interacting Effects Of Marital Status And Health Insurance On Long-Term Colon Cancer Survival In California, 1995-2014, Derek Campbell, Kevin M. Gorey, Isaac N. Luginaah, Guangyong Zou, Caroline Hamm, Eric J. Holowaty Jan 2016

Gender Differences On The Interacting Effects Of Marital Status And Health Insurance On Long-Term Colon Cancer Survival In California, 1995-2014, Derek Campbell, Kevin M. Gorey, Isaac N. Luginaah, Guangyong Zou, Caroline Hamm, Eric J. Holowaty

Social Work Publications

Objectives. Long-term colon cancer survival is not well explained by main effects. We explored the interaction of age, gender, marital status, health insurance and poverty on 10-year colon cancer survival.

Methods. California registry data were analyzed for 5,776 people diagnosed from 1995 to 2000; followed until 2014. Census data classified neighborhood poverty. We tested interactions with regressions and described them with standardized rates and rate ratios (RR).

Results. The 5-way interaction was significant, suggesting larger 4-way disadvantages among non-Medicare-eligible people. A significant 4-way interaction was a 3-way interaction in non-high poverty neighborhoods only. Private insurance was protective for unmarried …


Colon Cancer Care And Survival: Income And Insurance Are More Predictive In The Usa, Community Primary Care Physician Supply More So In Canada, Kevin M. Gorey, Sindu M. Kanjeekal, Frances C.

Colon Cancer Care And Survival: Income And Insurance Are More Predictive In The Usa, Community Primary Care Physician Supply More So In Canada, Kevin M. Gorey, Sindu M. Kanjeekal, Frances C. Wright, Caroline Hamm, Isaac N. Luginaah, Emma Bartfay, Guangyong Zou, Erc J. Holowaty, Nancy L. Richter

Social Work Publications

Background: Our research group advanced a health insurance theory to explain Canada’s cancer care advantages over America. The late Barbara Starfield theorized that Canada’s greater primary care-orientation also plays a critically protective role. We tested the resultant Starfield-Gorey theory by examining the effects of poverty, health insurance and physician supplies, primary care and specialists, on colon cancer care in Ontario and California.

Methods: We analyzed registry data for people with non-metastasized colon cancer from Ontario (n = 2,060) and California (n = 4,574) diagnosed between 1996 and 2000 and followed to 2010. We obtained census tract-based socioeconomic data from population …


Breast Cancer Among Women Living In Poverty: Better Care In Canada Than In The United States, Kevin M. Gorey, Nancy L. Richter, Isaac N. Luginaah, Caroline Hamm, Eric J. Holowaty, Guangyong Zou, Madhan K. Balagurusamy Apr 2015

Breast Cancer Among Women Living In Poverty: Better Care In Canada Than In The United States, Kevin M. Gorey, Nancy L. Richter, Isaac N. Luginaah, Caroline Hamm, Eric J. Holowaty, Guangyong Zou, Madhan K. Balagurusamy

Social Work Publications

This historical study estimated the protective effects of a universally accessible, single-payer health care system versus a multipayer system that leaves many uninsured or underinsured by comparing breast cancer care of women living in high-poverty neighborhoods in Ontario and California between 1996 and 2011. Women in Canada experienced better care, particularly as compared with women who were inadequately insured in the United States. Women in Canada were diagnosed earlier (rate ratio [RR] = 1.12) and enjoyed better access to breast conserving surgery (RR = 1.48), radiation (RR = 1.60), and hormone therapies (RR = 1.78). Women living in high-poverty Canadian …


Multiplicative Disadvantage Of Being An Unmarried And Inadequately Insured Woman Living In Poverty With Colon Cancer: Historical Cohort Exploration In California, Naomi R. Levitz, Sundus Haji-Jama, Tonya Munro, Kevin M. Gorey Feb 2015

Multiplicative Disadvantage Of Being An Unmarried And Inadequately Insured Woman Living In Poverty With Colon Cancer: Historical Cohort Exploration In California, Naomi R. Levitz, Sundus Haji-Jama, Tonya Munro, Kevin M. Gorey

Social Work Publications

Background: Many Americans diagnosed with colon cancer do not receive indicated chemotherapy. Certain unmarried women may be particularly disadvantaged. A 3-way interaction of the multiplicative disadvantages of being an unmarried and inadequately insured woman living in poverty was explored. Methods: California registry data were analyzed for 2,319 women diagnosed with stage II to IV colon cancer between 1996 and 2000 and followed until 2014. Socioeconomic data from the 2000 census classified neighborhoods as high poverty (≥30% of households poor), middle (5–29%) or low poverty (<5% poor). Primary health insurance was private, Medicare, Medicaid or none. Comparisons of chemotherapy rates used standardized rate ratios (RR). We respectively used logistic and Cox regression models to assess chemotherapy and survival. Results: A statistically significant 3-way marital status by health insurance by poverty interaction effect on chemotherapy receipt was observed. Chemotherapy rates did not differ between unmarried (39.0%) and married (39.7%) women who lived in lower poverty neighborhoods and were privately insured. But unmarried women (27.3%) were 26% less likely to receive chemotherapy than were married women (37.1%, RR = 0.74, 95% CI 0.58, 0.95) who lived in high poverty neighborhoods and were publicly insured or uninsured. When this interaction and the main effects of health insurance, poverty and chemotherapy were accounted for, survival did not differ by marital status. Conclusions: The multiplicative barrier to colon cancer care that results from being inadequately insured and living in poverty is worse for unmarried than married women. Poverty is more prevalent among unmarried women and they have fewer assets so they are probably less able to absorb the indirect and direct, but uncovered, costs of colon cancer care. There seem to be structural inequities related to the institutions of marriage, work and health care that particularly disadvantage unmarried women that policy makers ought to be cognizant of as future reforms of the American health care system are considered.

Social Work Publications

Extremely poor Canadian women were recently observed to be largely advantaged on most aspects of breast cancer care as compared with similarly poor, but much less adequately insured, women in the United States. This historical study systematically replicated the protective effects of single- versus multipayer health care by comparing colon cancer care among cohorts of extremely poor women in California and Ontario between 1996 and 2011. The Canadian women were again observed to have been largely advantaged. They were more likely to have received indicated surgery and chemotherapy, and their wait times for care were significantly shorter. Consequently, the Canadian …

The Supply Of Physicians And Care For Breast Cancer In Ontario And California, 1998 To 2006, Kevin M. Gorey, Isaac N. Luginaah, Caroline Hamm, Madhan K. Balagurusamy, Eric J. Holowaty

Social Work Publications

INTRODUCTION: We examined the differential effects of the supply of physicians on care for breast cancer in Ontario and California. We then used criteria for optimum care for breast cancer to estimate the regional needs for the supply of physicians.

METHODS: Ontario and California registries provided 951 and 984 instances of breast cancer diagnosed between 1998 and 2000 and followed until 2006. These cohorts were joined with the supply of county-level primary care physicians (PCPs) and specialists in cancer care and compared on care for breast cancer.

RESULTS: Significant protective PCP thresholds (7.75 to = 8.25 PCPs per 10 000 …

Associations Of Physician Supplies With Colon Cancer Care In Ontario And California, 1996 To 2006, Kevin M. Gorey

Social Work Publications

BACKGROUND: This study examined the differential effects of physician supplies on colon cancer care in Ontario and California. The associations of physician supplies with colon cancer stage at diagnosis, receipt of surgery and adjuvant chemotherapy, and 5-year survival were observed within each country and compared between-country.

METHODS: Random samples of Ontario and California cancer registries provided 2,461 and 2,200 colon cancer cases that were diagnosed between 1996 and 2000, and followed until 2006. Both registries included data on the stage of disease at the time of diagnosis, receipt of cancer-directed surgery, receipt of adjuvant chemotherapy, and survival. Census tract-level data …


Effects Of Socioeconomic Status On Colon Cancer Treatment Accessibility And Survival In Toronto, Ontario, And San Francisco, California, 1996-2006, Kevin M. Gorey, Isaac N. Luginaah, Emma Bartfay, Karen Y. Fung, Eric J. Holowaty, Frances C. Wright, Caroline Hamm, Sindu M. Kanjeekal Jan 2011

Effects Of Socioeconomic Status On Colon Cancer Treatment Accessibility And Survival In Toronto, Ontario, And San Francisco, California, 1996-2006, Kevin M. Gorey, Isaac N. Luginaah, Emma Bartfay, Karen Y. Fung, Eric J. Holowaty, Frances C. Wright, Caroline Hamm, Sindu M. Kanjeekal

Social Work Publications

OBJECTIVES: We examined the differential effects of socioeconomic status on colon cancer care and survival in Toronto, Ontario, Canada, and San Francisco, California.

METHODS: We analyzed registry data for colon cancer patients from Ontario (n = 930) and California (n = 1014), diagnosed between 1996 and 2000 and followed until 2006, on stage, surgery, adjuvant chemotherapy, and survival. We obtained socioeconomic data for individuals' residences from population censuses.

RESULTS: Income was directly associated with lymph node evaluation, chemotherapy, and survival in San Francisco but not in Toronto. High-income persons had better survival rates in San Francisco than in Toronto. After …


Breast Cancer Care In Canada And The United States: Ecological Comparisons Of Extremely Impoverished And Affluent Urban Neighborhoods, Kevin M. Gorey Jan 2010

Breast Cancer Care In Canada And The United States: Ecological Comparisons Of Extremely Impoverished And Affluent Urban Neighborhoods, Kevin M. Gorey

Social Work Publications

This study examined the differential effect of extreme impoverishment on breast cancer care in urban Canada and the United States. Ontario and California registry-based samples diagnosed between 1998 and 2000 were followed until 2006. Extremely poor and affluent neighborhoods were compared. Poverty was associated with non-localized disease, surgical and radiation therapy (RT) waits, non-receipt of breast conserving surgery, RT and hormonal therapy, and shorter survival in California, but not in Ontario. Extremely poor Ontario women were consistently advantaged on care indices over their California counterparts. More inclusive health insurance coverage in Canada seems the most plausible explanation for such Canadian …


Income And Long-Term Breast Cancer Survival: Comparisons Of Vulnerable Urban Places In Ontario And California, Kevin M. Gorey Jan 2010

Income And Long-Term Breast Cancer Survival: Comparisons Of Vulnerable Urban Places In Ontario And California, Kevin M. Gorey

Social Work Publications

Effects of socioeconomic status on the long-term survival of 808 women with node-negative breast cancer in Canada and the United States were observed. Ontario and California samples diagnosed between 1988 and 1990 were followed until 2006. Socioeconomic data were taken from population censuses. Compared with their California counterparts, residents of low-income urban areas in Ontario experienced a significant 15-year survival advantage (RR = 1.66 [95% CI: 1.00, 2.76]). In these and other vulnerable, lower-middle- to working-class neighborhoods, significantly more Ontario residents gained access to adjuvant radiation therapy (RR = 1.75 [1.21, 2.53]) which seemed associated with better long-term survival (RR …


Physician Supply And Breast Cancer Survival, Kevin M. Gorey Jan 2010

Physician Supply And Breast Cancer Survival, Kevin M. Gorey

Social Work Publications

BACKGROUND: This study tested the hypothesis that physician supply thresholds are associated with breast cancer survival in Ontario.

METHODS: The 5-year survival of 17,820 female breast cancer patients diagnosed between 1995 and 1997 was surveilled until 2003 for all-cause mortality. Physician supply densities in 1991 and 2001 were computed for 49 Ontario regions.

RESULTS: There were independent threshold effects for general practitioners (GP; 7.25 per 10,000) and obstetrician/gynecologists (OB/GYN; 6 per 100,000) at or above which women with breast cancer were more likely to survive for 5 years. The respective risk of living in areas undersupplied with OB/GYN and GP …

Breast Cancer Survival In Ontario And California, 1998-2006: Socioeconomic Inequity Remains Much Greater In The United States, Kevin M. Gorey

Social Work Publications

This study re-examined the differential effect of socioeconomic status on the survival of women with breast cancer in Canada and the United States. Ontario and California cancer registries provided 1,913 cases from urban and rural places. Stage-adjusted cohorts (1998-2000) were followed until 2006. Socioeconomic data were taken from population censuses. SES-survival associations were observed in California, but not in Ontario, and Canadian survival advantages in low-income areas were replicated. A better controlled and updated comparison reaffirmed the equity advantage of Canadian health care.

Breast Cancer Survival In Canada And The Usa: Meta-Analytic Evidence Of A Canadian Advantage In Low-Income Areas, Kevin M. Gorey

Social Work Publications

BACKGROUND: This study tested the hypothesis that relatively poor Canadian women with breast cancer have a survival advantage over their counterparts in the USA.

METHODS: Seventy-eight independent retrospective cohort (incidence between 1984 and 2000, followed until 2006) outcomes were synthesized. Fixed effects meta-regression models compared women with breast cancer in low-income areas of Canada and the USA.

RESULTS: Low-income Canadian women were advantaged on survival [rate ratio (RR) = 1.14; 95% confidence interval (CI) 1.13-1.15] and their advantage was even larger among women <65 years of age who are not yet eligible for Medicare coverage in the USA (RR = 1.21, 95% CI 1.18-1.24). Canadian advantages were also larger for node positive breast cancer, which may present with greater clinical and managerial discretion (RR = 1.40, 95% CI 1.30-1.50), and smaller when Hawaii, the state providing the most Canadian-like access, was the US comparator (RR = 1.12, 95% CI 1.01-1.20).

CONCLUSIONS: More inclusive health care insurance coverage in Canada vs the USA, particularly among each country's relatively …


Wait Times For Surgical And Adjuvant Radiation Treatment Of Breast Cancer In Canada And The United States: Greater Socioeconomic Inequity In America, Kevin M. Gorey Jan 2009

Wait Times For Surgical And Adjuvant Radiation Treatment Of Breast Cancer In Canada And The United States: Greater Socioeconomic Inequity In America, Kevin M. Gorey

Social Work Publications

PURPOSE: The demand for cancer care has increased among aging North American populations as cancer treatment innovations have proliferated. Gaps between supply and demand may be growing. This study examined whether socioeconomic status has a differential effect on waits for surgical and adjuvant radiation treatment (RT) of breast cancer in Canada and the US.

METHODS: Ontario and California cancer registries provided 929 and 984 breast cancer cases diagnosed between 1998 and 2000 in diverse urban and rural places. Residence-based socioeconomic data were taken from censuses. Cancer care variables were reliably abstracted from health records: stage, receipt of surgery and RT, …

Associations Of Physician Supplies With Breast Cancer Stage At Diagnosis And Survival In Ontario, 1988 To 2006, Kevin M. Gorey

Social Work Publications

BACKGROUND: The authors examined whether the supply of primary care physicians had protective effects on breast cancer stage and survival in Ontario and whether supply losses during the 1990s were associated with diminished protection.

METHODS: Random samples of the Ontario Cancer Registry, respectively, provided 879 women and 951 women who were diagnosed with breast cancer between 1988 and 1990 (followed until 1996) and 1998 and 2000 (followed until 2006), respectively. Active physician supply data (1991 and 2001) joined to each woman's census division of residence was taken from the Scott's Medical Database.

RESULTS: Protective thresholds were observed among the earlier …

Increased Racial Differences On Breast Cancer Care And Survival In America: Historical Evidence Consistent With A Health Insurance Hypothesis, 1975-2001, Kevin M. Gorey

Social Work Publications

PURPOSE: This study examined whether race/ethnicity had differential effects on breast cancer care and survival across age strata and cohorts within stages of disease.

METHODS: The Detroit Cancer Registry provided 25,997 breast cancer cases. African American and non-Hispanic white, older Medicare-eligible and younger non-eligible women were compared. Successive historical cohorts (1975-1980 and 1990-1995) were, respectively, followed until 1986 and 2001.

RESULTS: African American disadvantages on survival and treatments increased significantly, particularly among younger women who were much more likely to be uninsured. Within node positive disease all treatment disadvantages among younger African American women disappeared with socioeconomic adjustment.

CONCLUSIONS: Growth …

Lower Adherence To Screening Mammography Guidelines Among Ethnic Minority Women In America: A Meta-Analytic Review, Rebecca J. Purc-Stephenson, Kevin M. Gorey

Social Work Publications

OBJECTIVE: This study investigates the association between ethnic minority status and receiving a screening mammogram within the past 2 years among American women over 50.

METHOD: The findings from 33 studies identified from interdisciplinary research databases (1980 to 2006) were synthesized. Separate pooled analyses compared white non-Hispanics to African Americans (28 outcomes), Hispanics (18 outcomes), and Asian/Pacific Islanders (10 outcomes).

RESULTS: Using the random effects model, results showed that African Americans were screened less than white non-Hispanics at a marginal level (OR 0.87, 95% CI 0.75, 1.00). Larger and significant discrepancies were observed for Hispanics (OR 0.65, 95% CI 0.50, …

Cancer Survival In Ontario, 1986-2003: Evidence Of Equitable Advances Across Most Diverse Urban And Rural Places, Kevin M. Gorey

Social Work Publications

OBJECTIVES: This study examined whether place and socio-economic status had differential effects on the survival of women diagnosed with breast cancer in Ontario during the 1980s and the 1990s.

METHODS: The Ontario Cancer Registry provided 29,934 primary malignant breast cancer cases. Successive historical cohorts (1986-1988 and 1995-1997) were, respectively, followed until 1994 and 2003. Diverse places were compared: the greater metropolitan Toronto area, other cities, ranging in size from 50,000 to a million people, smaller towns and villages, and rural and remote areas. Socio-economic data for each woman's residence at the time of diagnosis were taken from population censuses.

RESULTS: …

Prevalent Low Income Status In Canadian And United States Metropolitan Areas, 1980 And 1990, Kevin M. Gorey

Social Work Publications

As compared to Toronto’s poor people, three to four-fold as many of upstate New York’s poor live in severely impoverished neighborhoods, areas where 40% or more of the residents have annual incomes below the federally established low income or poverty criterion. However, the prevalence of such extremely degraded living conditions increased similarly (two-fold) on both sides of the Canadian-US border during the 1980s. This urban problem, of the concentration of poor people, seems to predominantly be an inner-city problem in the US, whereas it was found to be nearly equivalently extant in the inner-city, mid-suburban and outlying suburban areas of …
