Cancer mortality rates among US and foreign-born individuals: United States 2005-2014
Hallowell BD , Endeshaw M , McKenna MT , Senkomago V , Razzaghi H , Saraiya M . Prev Med 2019 126 105755 From 1970 to 2010 the foreign-born population in the United States has rapidly increased from 9.6 to 40.0 million individuals. Historically, differences in cancer rates have been observed between US-born and foreign-born individuals. However, comprehensive and up-to-date data on US cancer rates by birth place is lacking. To compare cancer mortality rates among foreign and US-born individuals, population-based cancer mortality data were obtained from the CDC's National Center for Health Statistics. Utilizing data recorded on death certificates, individuals were categorized as US-born or foreign-born. Annual population estimates were obtained from the American Community Survey. Age-adjusted mortality rates and rate ratios (RRs) for all cancer sites were calculated using SEER*Stat. A total of 5,670,535 deaths from malignant cancers were recorded in the US from 2005 to 2014 and 9% of deaths occurred among foreign-born individuals. Overall, foreign-born individuals had a 31% lower cancer mortality rate when compared to US-born individuals (Rate Ratio (RR): 0.69 (95% CI: 0.68-0.69)), and similar results were observed when stratifying by sex, race/ethnicity, age, and geographic region. However, foreign-born individuals did have significantly elevated cancer mortality rates for seven cancers sites, of which five were infection-related, including: nasopharynx (RR: 2.01), Kaposi Sarcoma (RR: 1.94), stomach (RR: 1.82), gallbladder (RR: 1.47), acute lymphocytic leukemia (RR: 1.27), liver and intrahepatic bile duct (RR: 1.24), and thyroid (RR: 1.22) cancers. Many of these deaths could be avoided through improved access to prevention, screening, and treatment services for immigrant populations in the US or in their country of origin. |
Cervical cancer death rates among U.S.- and foreign-born women: U.S., 2005-2014
Hallowell BD , Endeshaw M , McKenna MT , Senkomago V , Razzaghi H , Saraiya M . Am J Prev Med 2019 56 (6) 869-874 INTRODUCTION: Historically, foreign-born women in the U.S. are less likely to be screened and are more likely to die from cervical cancer when compared with their U.S.-born counterparts. In order to inform prevention efforts and reduce this health disparity, mortality data were obtained from the National Center for Health Statistics to describe cervical cancer mortality among U.S.- and foreign-born women. METHODS: Annual population estimates were obtained from the U.S. Census Bureau's American Community Survey from 2005 to 2014. From 2017 to 2018, age-adjusted mortality rates and rate ratios were calculated by nativity status, race/ethnicity, age, geographic region, and country of birth. RESULTS: From 2005 to 2014, a total of 5,924 deaths from cervical cancer were recorded among the foreign-born population, compared with 33,893 deaths among U.S.-born women. Overall, foreign-born women had a lower cervical cancer mortality rate when compared with the U.S.-born women (rate ratio=0.95, 95% CI=0.92, 0.97). However, older foreign-born women had significantly higher mortality rates compared with U.S.-born women: aged 65-79 years (rate ratio=1.15, 95% CI=1.09, 1.22) and >/=80 years (rate ratio=1.43, 95% CI=1.32, 1.55). Women born in Mexico had significantly elevated rates of cervical cancer mortality (rate ratio=1.35, 95% CI=1.27, 1.42) when compared with U.S.-born women. CONCLUSIONS: Efforts that work to increase cervical cancer screening access and guideline compliance might further reduce the cervical cancer deaths in the U.S., and the excess burden observed among older foreign-born women. |
Gastric cancer mortality rates among US and foreign-born persons: United States 2005-2014
Hallowell BD , Endeshaw M , Senkomago V , Razzaghi H , McKenna MT , Saraiya M . Gastric Cancer 2019 22 (5) 1081-1085 BACKGROUND: Historically, foreign-born individuals in the US have had an elevated risk of dying from gastric cancer when compared to US-born individuals. This is primarily due to factors that occur prior to their immigration to the US, including diet and underlying risk of H. pylori infection. METHODS: National mortality data from 2005 to 2014 were obtained from the CDC's National Center for Health Statistics. Annual population estimates were obtained from the US Census Bureau's American Community Survey for foreign-born and US-born persons. Age-adjusted gastric cancer mortality rates and rate ratios (RR) were calculated stratified by birth place, age, race/ethnicity, and geographic location. RESULTS: From 2005 to 2014, 111,718 deaths from malignant gastric cancer occurred in the US, of which 24,583 (22%) occurred among foreign-born individuals. Overall, foreign-born individuals had higher mortality rates compared with US-born individuals (RR 1.82; 95% CI 1.80, 1.85) and this difference remained after stratifying by sex, age, and geographic location. However, this finding was primarily driven by the low rate of gastric cancer mortality among US-born whites, with similar mortality rates observed among all other foreign-born and US-born groups. Gastric cancer mortality rates significantly decreased during the study period overall (AAPC - 2.50; 95% CI - 3.21, - 1.79) with significant declines observed among US-born (AAPC - 2.81; 95% CI - 3.55, - 2.07) and the foreign-born (AAPC - 2.53; 95% CI - 3.20, - 1.86) population. CONCLUSIONS: Efforts directed at reducing the prevalence of gastric cancer risk factors could help reduce the elevated burden observed among foreign-born individuals and US-born minority groups. |
Trends in liver cancer mortality in the United States: Dual burden among foreign- and US-born persons
Endeshaw M , Hallowell BD , Razzaghi H , Senkomago V , McKenna MT , Saraiya M . Cancer 2018 125 (5) 726-734 BACKGROUND: Since the mid-1980s, the burden of liver cancer in the United States has doubled, with 31,411 new cases and 24,698 deaths occurring in 2014. Foreign-born individuals may be more likely to die of liver cancer than individuals in the general US-born population because of higher rates of hepatitis B infection, a low socioeconomic position, and language barriers that limit the receipt of early cancer detection and effective treatment. METHODS: To determine whether liver cancer mortality rates were higher among foreign-born individuals versus US-born individuals in the United States, population-based cancer mortality data were obtained from the National Center for Health Statistics of the Centers for Disease Control and Prevention. Annual population estimates were obtained from the US Census Bureau's American Community Survey. Age-adjusted mortality rates and rate ratios (RRs) for liver cancer stratified by birth place were calculated, and the average annual percent change (AAPC) was used to evaluate trends. RESULTS: A total of 198,557 deaths from liver and intrahepatic bile duct cancer were recorded during 2005-2014, and 16% occurred among foreign-born individuals. Overall, foreign-born individuals had a 24% higher risk of liver cancer mortality than US-born individuals (RR, 1.24; 95% confidence interval [CI], 1.22-1.25). Foreign-born individuals did not have any significant changes in liver cancer mortality rates overall, but among US-born individuals, liver cancer mortality rates significantly increased (AAPC, 2.7; 95% CI, 2.1-3.3). CONCLUSIONS: Efforts that address the major risk factors for liver cancer are needed to help to alleviate the health disparities observed among foreign-born individuals and reverse the increasing trend observed in the US-born population. |
CDC activities to enhance training in cancer prevention and control in field epidemiology training programs in low- and middle-income countries
Senkomago V , Joseph R , Sierra M , Van Dyne E , Endeshaw M , Duran D , Sugerman DE , Saraiya M . J Glob Oncol 2018 4 (4) 1-9 Cancer is one of the leading causes of morbidity and mortality worldwide. In 2012, there were > 14 million new cancer cases and > 8 million cancer deaths, with 70% of these deaths occurring in low- and middle-income countries (LMICs). Part of the success of cancer prevention and control efforts requires the development and strengthening of the public health workforce, particularly in LMICs where the cancer burden is the greatest. The US Centers for Disease Control and Prevention (CDC) supports workforce capacity development globally through Field Epidemiology Training Programs (FETPs) established in ministries of health in > 70 countries. To enhance training in cancer prevention and control in FETPs, the CDC has developed an open-access curriculum in applied cancer epidemiology and supports FETP trainees who conduct cancer-related planned projects. The curriculum contains modules on cancer registration, screening, and comprehensive cancer control that are particularly relevant to current cancer control efforts in many LMICs. Pilot testing of the curriculum showed an increase in trainees' cancer knowledge and covered content trainees found to be relevant to their field epidemiology training and projects and future work in cancer prevention and control. Since 2013, the CDC has supported 13 trainees with cancer-related projects; two have published articles, two have presented their results at international conferences, and others are writing manuscripts on their project outcomes. Through the development of an open-access applied cancer epidemiology curriculum and by supporting cancer-related projects for FETP trainees, the CDC provided technical assistance for LMICs to build capacity for cancer prevention and control efforts. |
Cervical cancer screening among women by birthplace and percent of lifetime living in the United States
Endeshaw M , Clarke T , Senkomago V , Saraiya M . J Low Genit Tract Dis 2018 22 (4) 280-287 OBJECTIVE: The aim of the study was to provide national estimates of Pap test receipt, by birthplace, and percent of lifetime in the United States (US). MATERIALS AND METHODS: Pooled nationally representative data (2005, 2008, 2013, 2015) from the National Health Interview Survey were used to examine differences in Pap test receipt among adult US women by birthplace and percent of lifetime in the US. Descriptive estimates were age-adjusted. Regression models were adjusted for selected sociodemographic and healthcare access and utilization factors and presented as predicted margins. RESULTS: Foreign-born women 18 years and older were more than twice as likely to have never received a Pap test compared with US-born women (18.6% vs 6.8%). Regression models showed that foreign-born women from Mexico (9.8%), South America (12.6%), Caribbean (14.6%), Southeast Asia (13.7%), Central Asia (20.4%), South Asia (22.9%), Middle East (25.0%), Africa (27.8%), Europe (16.4%), and Former Soviet Union (28.2%) were more likely to be unscreened compared with US-born women (7.6%). Foreign-born women who spent less than 25% of their life in the US had higher prevalence of never having a Pap test (20%) compared with foreign-born who spent more than 25% of their life in the US (12.7%). CONCLUSIONS: Using national survey, we found that where a woman is born and the percent of her lifetime spent residing in the US do impact whether she gets screened at least once in her lifetime. IMPACT: These findings may inform cervical cancer screening efforts targeting foreign-born women. |
Challenges in recruiting African-born, US-based participants for HIV and tuberculosis research
Kerani R , Narita M , Lipira L , Endeshaw M , Holmes KK , Golden MR . J Immigr Minor Health 2018 21 (3) 533-539 Research is critical for developing HIV and tuberculosis (TB) programming for U.S. African-born communities, and depends on successful recruitment of African-born people. From January 2014 to June 2016, we recruited African-born people for HIV and TB research in King County, Washington. We compared the characteristics of study participants and the underlying populations of interest, and assessed recruitment strategies. Target enrollment for the HIV study was 167 participants; 51 participants (31%) were enrolled. Target enrollment for the TB study was 218 participants; 38 (17%) were successfully recruited. Of 249 prior TB patients we attempted to contact by phone, we reached 72 (33%). Multiple recruitment strategies were employed with variable impact. Study participants differed from the underlying populations in terms of gender, country of origin and language. Inequities in research participation and in meaningful opportunities for such participation may exacerbate existing health disparities. |
Estimation of insecticide persistence, biological activity and mosquito resistance to PermaNet(R) 2 long-lasting insecticidal nets over three to 32 months of use in Ethiopia
Anshebo GY , Graves PM , Smith SC , Wills AB , Damte M , Endeshaw T , Shargie EB , Gebre T , Mosher AW , Patterson AE , Emerson PM . Malar J 2014 13 (1) 80 BACKGROUND: Information is needed on the expected durability of insecticidal nets under operational conditions. The persistence of insecticidal efficacy is important to estimate the median serviceable life of nets under field conditions and to plan for net replacement. METHODS: Deltamethrin residue levels were evaluated by the proxy method of X-ray fluorescence spectrometry on 189 nets used for three to six months from nine sites, 220 nets used for 14-20 months from 11 sites, and 200 nets used for 26-32 months from ten sites in Ethiopia. A random sample of 16.5-20% of nets from each time period (total 112 of 609 nets) were tested by bioassay with susceptible mosquitoes, and nets used for 14-20 months and 26-32 months were also tested with wild caught mosquitoes. RESULTS: Mean insecticide levels estimated by X-ray fluorescence declined by 25.9% from baseline of 66.2 (SD 14.6) mg/m2 at three to six months to 44.1 (SD 21.2) mg/m2 at 14-20 months and by 30.8% to 41.1 (SD 18.9) mg/m2 at 26-32 months. More than 95% of nets retained greater than 10 mg/m2 of deltamethrin and over 79% had at least 25 mg/m2 at all time periods. By bioassay with susceptible Anopheles, mortality averaged 89.0% on 28 nets tested at three to six months, 93.3% on 44 nets at 14-20 months and 94.1% on 40 nets at 26-32 months. With wild caught mosquitoes, mortality averaged 85.4% (range 79.1 to 91.7%) at 14-20 months but had dropped significantly to 47.2% (39.8 to 54.7%) at 26-32 months. CONCLUSIONS: Insecticide residue level, as estimated by X-ray fluorescence, declined by about one third between three and six months and 14-20 months, but remained relatively stable and above minimum requirements thereafter up to 26-32 months. The insecticidal activity of PermaNet(R) 2.0 long-lasting insecticidal nets in the specified study area may be considered effective to susceptible mosquitoes at least for the duration indicated in this study (32 months). However, results indicated that resistance in the wild population is already rendering nets with optimum insecticide concentrations less effective in practice. |
Physical durability of PermaNet 2.0 long-lasting insecticidal nets over three to 32 months of use in Ethiopia
Wills AB , Smith SC , Anshebo GY , Graves PM , Endeshaw T , Shargie EB , Damte M , Gebre T , Mosher AW , Patterson AE , Tesema YB , Richards FO Jr , Emerson PM . Malar J 2013 12 (1) 242 BACKGROUND: Ethiopia scaled up net distribution markedly starting in 2006. Information on expected net life under field conditions (physical durability and persistence of insecticidal activity) is needed to improve planning for net replacement. Standardization of physical durability assessment methods is lacking. METHODS: Permanet(R)2.0 long-lasting insecticidal bed nets (LLINs), available for distribution in early 2007, were collected from households at three time intervals. The number, size and location of holes were recorded for 189 nets used for three to six months from nine sites (2007) and 220 nets used for 14 to 20 months from 11 sites (2008). In 2009, a "finger/fist" sizing method classified holes in 200 nets used for 26 to 32 months from ten sites into small (<2 cm), medium (> = 2 to < =10 cm) and large (>10 cm) sizes. A proportionate hole index based on both hole number and area was derived from these size classifications. RESULTS: After three to six months, 54.5% (95% CI 47.1-61.7%) of 189 LLINs had at least one hole 0.5 cm (in the longest axis) or larger; mean holes per net was 4.4 (SD 8.4), median was 1.0 (Inter Quartile Range [IQR] 0--5) and median size was 1 cm (IQR 1--2). At 14 to 20 months, 85.5% (95% CI 80.1-89.8%) of 220 nets had at least one hole with mean 29.1 (SD 50.1) and median 12 (IQR 3--36.5) holes per net, and median size of 1 cm (IQR 1--2). At 26 to 32 months, 92.5% of 200 nets had at least one hole with a mean of 62.2 (SD 205.4) and median of 23 (IQR 6--55.5) holes per net. The mean hole index was 24.3, 169.1 and 352.8 at the three time periods respectively. Repairs were rarely observed. The majority of holes were in the lower half of the net walls. The proportion of nets in 'poor' condition (hole index >300) increased from 0% at three to six months to 30% at 26 to 32 months. CONCLUSIONS: Net damage began quickly: more than half the nets had holes by three to six months of use, with 40% of holes being larger than 2 cm. Holes continued to accumulate until 92.5% of nets had holes by 26 to 32 months of use. An almost complete lack of repairs shows the need for promoting proper use of nets and repairs, to increase LLIN longevity. Using the hole index, almost one third of the nets were classed as unusable and ineffective after two and a half years of potential use. |
Rapid increase in ownership and use of long-lasting insecticidal nets and decrease in prevalence of malaria in three regional States of Ethiopia (2006-2007)
Shargie EB , Ngondi J , Graves PM , Getachew A , Hwang J , Gebre T , Mosher AW , Ceccato P , Endeshaw T , Jima D , Tadesse Z , Tenaw E , Reithinger R , Emerson PM , Richards FO , Ghebreyesus TA . J Trop Med 2010 2010 Following recent large scale-up of malaria control interventions in Ethiopia, this study aimed to compare ownership and use of long-lasting insecticidal nets (LLIN), and the change in malaria prevalence using two population-based household surveys in three regions of the country. Each survey used multistage cluster random sampling with 25 households per cluster. Household net ownership tripled from 19.6% in 2006 to 68.4% in 2007, with mean LLIN per household increasing from 0.3 to 1.2. Net use overall more than doubled from 15.3% to 34.5%, but in households owning LLIN, use declined from 71.7% to 48.3%. Parasitemia declined from 4.1% to 0.4%. Large scale-up of net ownership over a short period of time was possible. However, a large increase in net ownership was not necessarily mirrored directly by increased net use. Better targeting of nets to malaria-risk areas and sustained behavioural change communication are needed to increase and maintain net use. |
