Incidence Trends of Breast Cancer Molecular Subtypes by Age and Race/Ethnicity in the US From 2010 to 2016.

ABSTRACT: Importance:Breast cancer incidence trends by age and race/ethnicity have been documented; it is less clear whether incidence trends of breast cancer molecular subtypes, which differ in risk factors and prognosis, also vary by age and race/ethnicity. Objective:To estimate annual percentage changes and trends in breast cancer molecular subtype-specific incidence rates by age at diagnosis and race/ethnicity in the US. Design, Setting, and Participants:This population-based cross-sectional study included data from 18 cancer registries in the Surveillance, Epidemiology and End Results database, capturing 27.8% of the US population. Hispanic and non-Hispanic White, Black, and Asian/Pacific Islander women aged 25 to 84 years who were diagnosed with invasive breast cancer from 2010 to 2016 were included. Data were analyzed from September 2019 to February 2020. Exposures:Age and racial/ethnic groups. Main Outcomes and Measures:Annual percentage change (APC) and 95% CIs for age-standardized breast cancer incidence rates stratified by 15-year age groups at diagnosis and race/ethnicity. Results:Of 320?124 women diagnosed with breast cancer from 2010 to 2016, 232?558 (72.6%) had luminal A, 35?869 (11.2%) had luminal B, 15?472 (4.8%) had ERBB2-enriched, and 36?225 (11.3%) had triple-negative breast cancer subtypes. Luminal A breast cancer incidence rates increased in non-Hispanic White (APC from 2010-2014, 2.3%; 95% CI, 0.3% to 4.2%) and non-Hispanic Asian/Pacific Islander (APC from 2010-2016, 2.5%; 95% CI, 0.6% to 4.5%) women aged 40 to 54 years, and in non-Hispanic Black women aged 55 to 69 years women (APC from 2010-2012, 4.9%; 95% CI, 4.0% to 5.7%). Luminal B breast cancer incidence rates increased in all age groups for non-Hispanic White women (age 25-39 years: APC, 4.3%; 95% CI, 1.5% to 7.%2; age 40-54 years: APC, 3.5%; 95% CI, 1.4% to 5.6%; age 55-69 years: APC, 3.3%; 95% CI, 1.6% to 5.0%; age 70-84 years: APC, 3.9%; 95% CI, 1.9% to 6.0%) and Hispanic women (age 25-39 years: APC, 8.4%; 95% CI, 5.8% to 11.2%; age 40-54 years: APC, 6.1%; 95% CI, 4.2% to 8.0%; age 55-69 years: APC, 5.1%; 95% CI, 1.5% to 8.8%; age 70-84 years: APC, 7.1%; 95% CI, 4.6% to 9.6%) and in non-Hispanic Asian/Pacific Islander women aged 55 to 69 years (APC, 6.1%; 95% CI, 3.2% to 9.0%). ERBB2-enriched breast cancer incidence rates increased in non-Hispanic White women aged 25 to 39 years (APC, 4.7%; 95% CI, 1.5% to 8.0%). Triple-negative breast cancer incidence rates decreased in non-Hispanic White women aged 40 to 54 years (APC, -2.3%; 95% CI, -3.8% to -0.7%) and 55 to 69 years (APC, -3.6%; 95% CI, -5.1% to -2.1%) and in non-Hispanic Black women aged 55 to 69 years (APC, -1.4%; 95% CI, -2.2% to -0.7%). Conclusions and Relevance:The findings of this cross-sectional study suggest that between 2010 and 2016, luminal A and luminal B breast cancer incidence rates increased for many racial/ethnic and age groups, with the largest increases observed for luminal B breast cancer. ERBB2-enriched breast cancer incidence rates increased for young non-Hispanic White women, while triple-negative breast cancer incidence rates decreased for midlife non-Hispanic White and non-Hispanic Black women. These trends may suggest changes in breast cancer risk factor profiles across age and racial/ethnic groups.

Project description:ImportanceDespite recent advances in therapies for heart failure (HF), deaths from HF are increasing, with persistent disparities between Black and White adults. Recent national trends in the prevalence of HF need to be clarified to appropriately allocate resources and develop effective preventive interventions.ObjectivesTo examine the prevalence of ambulatory HF overall and by race/ethnicity and age and the temporal changes in HF prevalence between 2001 and 2016.Design, setting, and participantsThis cross-sectional study of nationally representative data collected biennially through the National Health and Nutrition Examination Survey (NHANES) from January 1, 2001, to December 31, 2016, assessed nonpregnant adults 35 years and older who self-identified as non-Hispanic Black, non-Hispanic White, or Mexican American. Data analysis was performed from November 16, 2019, to April 12, 2020.ExposuresSurvey period, race/ethnicity, and age group.Main outcomes and measuresAge-standardized prevalence was calculated within 4-year survey periods (2001-2004, 2005-2008, 2009-2012, and 2013-2016) based on self-report of ambulatory HF overall and by race/ethnicity and age group (35-64 and ≥65 years). Weighted multivariable logistic regression was used to examine trends in ambulatory HF prevalence over time by race/ethnicity and age group.ResultsA total of 26 097 participants (mean [SD] age, 55.9 [10.7] years; 13 192 [52%] female; 6519 [12%] non-Hispanic Black; and 4906 [7%] Mexican American) were studied. Overall age-standardized prevalence (per 100 000 population) of ambulatory HF was 3184 (95% CI, 2641-3728) from 2001 to 2005 and 3045 (95% CI, 2651-3438) from 2013 to 2016. The prevalence of ambulatory HF was highest among non-Hispanic Black adults: from 2013 to 2016, HF prevalence (per 100 000 population) was 5017 (95% CI, 3755-6279) among non-Hispanic Black adults, 2746 (95% CI, 2313-3179) among non-Hispanic White adults, and 2508 (95% CI, 1154-3862) among Mexican American adults. Differences between White and Black adults in HF prevalence were also present in younger and middle-aged adults (eg, 35-64 years of age in 2013-2016: 3864 [95% CI, 2369-5359] for non-Hispanic Black adults vs 1297 [95% CI, 878-1716] for non-Hispanic White adults).Conclusions and relevanceThis study found that a high burden of ambulatory HF persisted between 2001 and 2016 in the US. Disparities were most prominent by age group. Alongside prevention and aggressive management of risk factors, targeted efforts aimed at mitigating racial disparities are needed.

Project description:IntroductionAlthough there are racial/ethnic differences in cigarette use, little is known about how non-cigarette tobacco use differs among racial/ethnic groups. This study investigated trends in cigar use from 2002 to 2016, by racial/ethnic group, in nationally representative US data.MethodsData were drawn from the 2002-2016 National Survey on Drug Use and Health public use data files (total analytic sample n = 630 547 including 54 060 past-month cigar users). Linear time trends of past-month cigar use were examined by racial/ethnic group (Non-Hispanic [NH] White, NH Black, Hispanic, NH Other/Mixed Race/Ethnicity) using logistic regression models.ResultsIn 2016, the prevalence of past-month cigar use was significantly higher among NH Black respondents than among other racial/ethnic groups (ps < .001). Cigar use was also higher among NH White respondents than among Hispanic and NH Other/Mixed Race/Ethnicity respondents. The year by racial/ethnic group interaction was significant (p < .001). Past-month cigar use decreased significantly from 2002 to 2016 among NH White and Hispanic respondents (ps = .001), whereas no change in prevalence was observed among NH Black (p = .779) and NH Other/Mixed Race/Ethnicity respondents (p = .152). Cigar use decreased for NH White men (p < .001) and did not change for NH White women (p = .884). Conversely, cigar use increased for NH Black women (p < .001) and did not change for NH Black men (p = .546).ConclusionsCigar use remains significantly more common among NH Black individuals in the United States and is not declining among NH Black and NH Other/Mixed Race/Ethnicity individuals over time, in contrast to declines among NH White and Hispanic individuals.ImplicationsThis study identified racial/ethnic differences in trends in past-month cigar use over 15 years among annual cross-sectional samples of US individuals. The highest prevalence of cigar use in 2016 was found among NH Black individuals. In addition, cigar use prevalence did not decline from 2002 to 2016 among NH Black and NH Other/Mixed Race/Ethnicity groups over time, in contrast to NH White and Hispanic groups. Further, cigar use increased over time for NH Black women. Targeted public health and clinical efforts may be needed to decrease the prevalence of cigar use, especially for NH Black individuals.

Project description:Listeria monocytogenes is a foodborne pathogen that disproportionally affects pregnant females, older adults, and immunocompromised individuals. Using U.S. Foodborne Diseases Active Surveillance Network (FoodNet) surveillance data, we examined listeriosis incidence rates and rate ratios (RRs) by age, sex, race/ethnicity, and pregnancy status across three periods from 2008 to 2016, as recent incidence trends in U.S. subgroups had not been evaluated. The invasive listeriosis annual incidence rate per 100,000 for 2008-2016 was 0.28 cases among the general population (excluding pregnant females), and 3.73 cases among pregnant females. For adults ≥70 years, the annual incidence rate per 100,000 was 1.33 cases. No significant change in estimated listeriosis incidence was found over the 2008-2016 period, except for a small, but significantly lower pregnancy-associated rate in 2011-2013 when compared with 2008-2010. Among the nonpregnancy-associated cases, RRs increased with age from 0.43 (95% confidence interval: 0.25-0.73) for 0- to 14-year olds to 44.9 (33.5-60.0) for ≥85-year olds, compared with 15- to 44-year olds. Males had an incidence of 1.28 (1.12-1.45) times that of females. Compared with non-Hispanic whites, the incidence was 1.57 (1.18-1.20) times higher among non-Hispanic Asians, 1.49 (1.22-1.83) among non-Hispanic blacks, and 1.73 (1.15-2.62) among Hispanics. Among females of childbearing age, non-Hispanic Asian females had 2.72 (1.51-4.89) and Hispanic females 3.13 (2.12-4.89) times higher incidence than non-Hispanic whites. We observed a higher percentage of deaths among older patient groups compared with 15- to 44-year olds. This study is the first characterizing higher RRs for listeriosis in the United States among non-Hispanic blacks and Asians compared with non-Hispanic whites. This information for public health risk managers may spur further research to understand if differences in listeriosis rates relate to differences in consumption patterns of foods with higher contamination levels, food handling practices, comorbidities, immunodeficiencies, health care access, or other factors.
