RESUMO

STUDY OBJECTIVES: There are limited data depicting the association between high risk of OSA and the levels of inflammatory markers in a population-based sample free from CVD. In a large U.S. cohort enriched with a Hispanic population and free of cardiovascular disease (CVD), we aimed to assess the association between high risk of obstructive sleep apnea (OSA) and inflammatory markers. METHODS: We analyzed data for 2359 clinical CVD-free participants from the Miami Heart Study, aged 40-65 (May 2015 - Sept 2018). High risk of OSA included those with a high risk using the Berlin questionnaire. Poisson regression analyses were utilized to examine the associations between high risk of OSA (reference: low risk of OSA) and hs-CRP, IL-6, and TNF-α levels (continuous) in univariate and multivariate models (adjusting for age, sex, race/ethnicity, and BMI, diabetes, hypertension, high cholesterol, and smoking). RESULTS: 552 (28%) participants were categorized as having a high risk of OSA. Patients with a high risk of OSA had higher median values of hs-CRP (2.3 vs. 1.0), IL-6 (1.9 vs. 1.4), and TNF-α (1.2 vs. 1.1) when compared to those with a low risk of OSA (all p < 0.001). When adjusting for age, sex, and race/ethnicity, the mean difference between patients with high and low risk of OSA in hs-CRP was 2.04 (95% CI 1.85, 2.23), and 0.73 (95% CI 0.57, 0.89) in IL-6. These differences were attenuated when further adjusting for CVD risk factors but remained statistically significant for hs-CRP: (0.38, 95% CI 0.21, 0.55). CONCLUSIONS: After accounting for CVD risk factors, individuals at high risk of OSA had significantly higher levels of hs-CRP, suggesting that OSA screening identified subclinical inflammation in this population sample of individuals free of CVD.

RESUMO

BACKGROUND: Social determinants of health (SDOH) play a significant role in the development of cardiovascular risk factors. We investigated SDOH associations with cardiovascular risk factors among Asian American subgroups. METHODS AND RESULTS: We utilized the National Health Interview Survey, a nationally representative survey of US adults, years 2013 to 2018. SDOH variables were categorized into economic stability, neighborhood and social cohesion, food security, education, and health care utilization. SDOH score was created by categorizing 27 SDOH variables as 0 (favorable) or 1 (unfavorable). Self-reported cardiovascular risk factors included diabetes, high cholesterol, high blood pressure, obesity, insufficient physical activity, suboptimal sleep, and nicotine exposure. Among 6395 Asian adults aged ≥18 years, 22.1% self-identified as Filipino, 21.6% as Asian Indian, 21.0% as Chinese, and 35.3% as other Asian. From multivariable-adjusted logistic regression models, each SD increment of SDOH score was associated with higher odds of diabetes among Chinese (odds ratio [OR], 1.45; 95% CI, 1.04-2.03) and Filipino (OR, 1.24; 95% CI, 1.02-1.51) adults; high blood pressure among Filipino adults (OR, 1.28; 95% CI, 1.03-1.60); insufficient physical activity among Asian Indian (OR, 1.42; 95% CI, 1.22-1.65), Chinese (OR, 1.58; 95% CI, 1.33-1.88), and Filipino (OR, 1.24; 95% CI, 1.06-1.46) adults; suboptimal sleep among Asian Indian adults (OR, 1.20; 95% CI, 1.01-1.42); and nicotine exposure among Chinese (OR, 1.56; 95% CI, 1.15-2.11) and Filipino (OR, 1.50; 95% CI, 1.14-1.97) adults. CONCLUSIONS: Unfavorable SDOH are associated with higher odds of cardiovascular risk factors in Asian American subgroups. Culturally specific interventions addressing SDOH may help improve cardiovascular health among Asian Americans.

RESUMO

Background Although there is research on the impact of social determinants of health (SDOHs) on cardiovascular health, most existing evidence is based on individual SDOH components. We evaluated the impact of cumulative SDOH burden on cardiovascular risk factors, subclinical atherosclerosis, and incident cardiovascular disease events. Methods and Results We included 6479 participants from the MESA (Multi-Ethnic Study of Atherosclerosis). A weighted aggregate SDOH score representing the cumulative number of unfavorable SDOHs, identified from 14 components across 5 domains (economic stability, neighborhood and physical environment, community and social context, education, and health care system access) was calculated and divided into quartiles (quartile 4 being the least favorable). The impact of cumulative SDOH burden on cardiovascular risk factors (hypertension, diabetes, dyslipidemia, smoking, and obesity), systemic inflammation, subclinical atherosclerosis, and incident cardiovascular disease was evaluated. Increasing social disadvantage was associated with increased odds of all cardiovascular risk factors except dyslipidemia. Smoking was the risk factor most strongly associated with worse SDOH (odds ratio [OR], 2.67 for quartile 4 versus quartile 1 [95% CI, 2.13-3.34]). Participants within SDOH quartile 4 had 33% higher odds of increased high-sensitivity C-reactive protein (OR, 1.33 [95% CI, 1.11-1.60]) and 31% higher risk of all cardiovascular disease (hazard ratio, 1.31 [95% CI, 1.03-1.67]), yet no greater burden of subclinical atherosclerosis (OR, 1.01 [95% CI, 0.79-1.29]), when compared with those in quartile 1. Conclusions Increasing social disadvantage was associated with more prevalent cardiovascular risk factors, inflammation, and incident cardiovascular disease. These findings call for better identification of SDOHs in clinical practice and stronger measures to mitigate the higher SDOH burden among the socially disadvantaged to improve cardiovascular outcomes.

RESUMO

Objective: This cross-sectional study aims to better understand the heterogeneous associations of acculturation level on CV risk factors among disaggregated Asian subgroups. We hypothesize that the association between acculturation level and CV risk factors will differ significantly by Asian subgroup. Methods: We used the National Health Interview Survey (NHIS), a nationally representative US survey, years 2014-18. Acculturation was defined using: (a) years in the US, (b) US citizenship status, and (c) level of English proficiency. We created an acculturation index, categorized into low vs. high (scores of 0-3 and 4, respectively). Self-reported CV risk factors included diabetes, high cholesterol, hypertension, obesity, tobacco use, and sufficient physical activity. Rao-Scott Chi Square was used to compare age-standardized, weighted prevalence of CV risk factors between Asian subgroups. We used logistic regression analysis to assess associations between acculturation and CV risk factors, stratified by Asian subgroup. Results: The study sample consisted of 6,051 adults ≥ 18 years of age (53.9% female; mean age 46.6 [SE 0.33]). The distribution by race/ethnicity was Asian Indian 26.9%, Chinese 22.8%, Filipino 18.1%, and other Asian 32.3%. The association between acculturation and CV risk factors differed by Asian subgroups. From multivariable adjusted models, high vs. low acculturation was associated with: high cholesterol amongst Asian Indian (OR=1.57, 95% CI: 1.11, 2.37) and other Asian (OR=1.48, 95% CI: 1.10, 2.01) adults, obesity amongst Filipino adults (OR= 1.62, 95% CI: 1.07, 2.45), and sufficient physical activity amongst Chinese (OR= 1.54, 95% CI: 1.09, 2.19) and Filipino adults (OR=1.58, 95% CI: 1.10, 2.27). Conclusion: This study demonstrates that acculturation is heterogeneously associated with higher prevalence of CV risk factors among Asian subgroups. More studies are needed to better understand these differences that can help to inform targeted, culturally specific interventions.

RESUMO

BACKGROUND: The burden of total coronary plaque, plaque subtypes, and high-risk plaque features was unknown in asymptomatic individuals from the general U.S. primary prevention population. OBJECTIVES: In a large, asymptomatic U.S. cohort evaluated using coronary computed tomography angiography (CCTA), we aimed to assess the burden of total coronary plaque, plaque subtypes, and high-risk plaque features; the interplay between CCTA findings and coronary artery calcium (CAC) scores; and identify independent predictors of coronary plaque. METHODS: Cross-sectional analysis in the MiHeart (Miami Heart Study), a cohort of 2,359 asymptomatic individuals from the Greater Miami Area (mean age 53 years, 50% women, 47% Hispanic/Latino, 43% non-Hispanic White). We estimated the burden of CAC (=0, >0 to <100, ≥100), CCTA-based plaque features (any plaque, stenosis ≥50%, ≥70%, high-risk features), and their interplay. RESULTS: Overall, 58% participants had CAC = 0, 28% CAC >0 to <100, and 13% CAC ≥100. A total of 49% participants had plaque on the CCTA, including 16% among those with CAC = 0. Overall, 6% participants had coronary stenosis ≥50% (12% among those with coronary plaque), 1.8% had stenosis ≥70% (3.7% among those with plaque), and 7% had at least 1 coronary plaque with ≥1 high-risk feature (13.8% among those with plaque). Only 0.8% participants with CAC = 0 had stenosis ≥50%, 0.1% stenosis ≥70%, and 2.3% plaque with high-risk features. In logistic regression models, independent predictors of coronary plaque and high-risk plaque were older age, male sex, tobacco use, diabetes, overweight, and obesity. Male sex, overweight, and obesity were independent predictors of plaque if CAC = 0. CONCLUSIONS: The Miami Heart Study confirms substantial prevalence of coronary plaque in asymptomatic individuals. Overall, 49% of participants had coronary plaque, 6% had stenosis ≥50%, and 7% had plaques with at least 1 high-risk feature. These proportions were 16%, 0.8%, and 2.3%, respectively, among those with CAC = 0. Longitudinal follow-up will shed further light on the prognostic implications of these findings in asymptomatic individuals.

RESUMO

Disparities in cardiovascular outcomes are persistent in our society. The objective was to track the trends before and after the passage of the Affordable Care Act in socioeconomic status (SES) disparities in utilization of cardiovascular disease (CVD) preventive services among nonelderly adults aged 18-64 years. This study used the National Health Interview Survey (2011-2017) to compare utilization of blood pressure, cholesterol, glycemic screening, and diet and smoking cessation advice over time between groups stratified by SES and race using difference-in-difference analysis. This study also measured the differences over time in specific vulnerable population subgroups (Hispanic, low-income and uninsured vs. White, middle-high-income, and insured). The study population included 176,961 surveyed individuals (mean age 40 [±13] years; 51% female; 67.7% non-Hispanic White) between 2011 and 2017, translating to 194.8 million nonelderly US adults per year. Most individuals were from high-income SES (40.0%), followed by middle-income (28.1%), low-income (13.6%), and lowest income SES (18.3%). The proportion of CVD preventive services increased over all SES categories through the study period. The biggest relative changes were seen among low-income individuals. The difference in blood pressure checks, cholesterol checks, and smoking cessation advise between high- and lowest income groups showed a statistically significant decrease at 5.2%, 4.8%, and 11.2%, respectively, between 2011 and 2017. The findings demonstrate a trend in reduction of CVD preventive care disparities between SES groups. However, a gap still exists, and this study highlights the need for continuous improvement to eliminate SES disparities.

RESUMO

OBJECTIVE: To examine the association of social determinants of health (SDOH) on prevalence of stroke in non-elderly adults (<65 years of age). METHODS: We used the National Health Interview Survey (2013-2017) database. The study population was stratified into younger (<45 years of age) and middle age (45 to 64 years of age) adults. For each individual, an SDOH aggregate score was calculated representing the cumulative number of individual unfavorable SDOH (present vs absent), identified from 39 subcomponents across five domains (economic stability, neighborhood, community and social context, food, education, and health care system access) and divided into quartiles (quartile 1, most favorable; quartile 4, most unfavorable). Multivariable models tested the association between SDOH score quartiles and stroke. RESULTS: The age-adjusted prevalence of stroke was 1.4% in the study population (n=123,631; 58.2% (n=71,956) in patients <45 years of age). Young adults reported approximately 20% of all strokes. Participants with stroke had unfavorable responses to 36 of 39 SDOH; nearly half (48%) of all strokes were reported by participants in the highest SDOH score quartile. A stepwise increase in age-adjusted stroke prevalence was observed across increasing quartiles of SDOH (first, 0.6%; second, 0.9%; third, 1.4%; and fourth, 2.9%). After accounting for demographics and cardiovascular disease risk factors, participants in the fourth vs first quartile had higher odds of stroke (odds ratio, 2.78; 95% CI, 2.25 to 3.45). CONCLUSION: Nearly half of all non-elderly individuals with stroke have an unfavorable SDOH profile. Standardized assessment of SDOH risk burden may inform targeted strategies to mitigate disparities in stroke burden and outcomes in this population.

RESUMO

OBJECTIVE: Health-related expenditures resulting from diabetes are rising in the U.S. Medication nonadherence is associated with worse health outcomes among adults with diabetes. We sought to examine the extent of reported cost-related medication nonadherence (CRN) in individuals with diabetes in the U.S. RESEARCH DESIGN AND METHODS: We studied adults age ≥18 years with self-reported diabetes from the National Health Interview Survey (NHIS) (2013-2018), a U.S. nationally representative survey. Adults reporting skipping doses, taking less medication, or delaying filling a prescription to save money in the past year were considered to have experienced CRN. The weighted prevalence of CRN was estimated overall and by age subgroups (<65 and ≥65 years). Logistic regression was used to identify sociodemographic characteristics independently associated with CRN. RESULTS: Of the 20,326 NHIS participants with diabetes, 17.6% (weighted 2.3 million) of those age <65 years reported CRN, compared with 6.9% (weighted 0.7 million) among those age ≥65 years. Financial hardship from medical bills, lack of insurance, low income, high comorbidity burden, and female sex were independently associated with CRN across age groups. Lack of insurance, duration of diabetes, current smoking, hypertension, and hypercholesterolemia were associated with higher odds of reporting CRN among the nonelderly but not among the elderly. Among the elderly, insulin use significantly increased the odds of reporting CRN (odds ratio 1.51; 95% CI 1.18, 1.92). CONCLUSIONS: In the U.S., one in six nonelderly and one in 14 elderly adults with diabetes reported CRN. Removing financial barriers to accessing medications may improve medication adherence among these patients, with the potential to improve their outcomes.

RESUMO

BACKGROUND: Middle Eastern (ME) immigrants are one of the fastest-growing groups in the US. Although ME countries have a high burden of atherosclerotic cardiovascular disease (ASCVD), the cardiovascular health status among ME immigrants in the US has not been studied in detail. This study aims to characterize the cardiovascular health status (CVD risk factors and ASCVD burden) among ME immigrants in the US. METHODS: We used 2012-2018 data from the National Health Interview Survey, a US nationally representative survey. ME origin, CVD risk factors, and ASCVD status were self-reported. We compared these to US-born non-Hispanic white (NHW) individuals in the US. RESULTS: Among 139,778 adults included, 886 (representing 1.3 million individuals, mean age 46.8) were of ME origin, and 138,892 were US-born NHWs (representing 150 million US adults, mean age 49.3). ME participants were more likely to have higher education, lower income and be uninsured. The age-adjusted prevalence of hypertension (22.4% vs 27.4%) and obesity (21.4% vs 31.4%) were significantly lower in ME vs NHW participants, respectively. There were no significant differences between the groups in the age-adjusted prevalence of ASCVD, diabetes, hyperlipidemia, and smoking. Only insufficient physical activity was higher among ME individuals. ME immigrants living in the US for 10 years or more reported higher age-adjusted prevalence of hypertension, hyperlipidemia, and ASCVD. CONCLUSIONS: ME immigrants in the US have lower odds of hypertension and obesity, and of having a suboptimal CRF profile compared to US-born NHWs. Further studies are needed to determine whether these findings are related to lower risk, selection of a healthier ME subgroup in NHIS, or possible under-detection of cardiovascular risk factors in ME immigrants living in the US.

RESUMO

AIMS: To evaluate the burden of cardiovascular risk factors and disease (CVD) among five Asian groups living in Catalonia (Spain): Indian, Pakistani, Bangladeshi, Filipino, and Chinese. METHODS AND RESULTS: Retrospective cohort study using the Catalan Health Surveillance System database including 42 488 Pakistanis, 40 745 Chinese, 21 705 Indians, 9544 Filipinos, and 6907 Bangladeshis; and 5.3 million native individuals ('locals'). We estimated the age-adjusted prevalence (as of 31 December 2019) and incidence (during 2019) of diabetes, hypertension, hyperlipidaemia, obesity, tobacco use, coronary heart disease (CHD), cerebrovascular disease, atrial fibrillation, and heart failure (HF). Bangladeshis had the highest prevalence of diabetes (17.4% men, 22.6% women) followed by Pakistanis. Bangladeshis also had the highest prevalence of hyperlipidaemia (23.6% men, 18.3% women), hypertension among women (24%), and incident tobacco use among men. Pakistani women had the highest prevalence of obesity (28%). For CHD, Bangladeshi men had the highest prevalence (7.3%), followed by Pakistanis (6.3%); and Pakistanis had the highest prevalence among women (3.2%). For HF, the prevalence in Pakistani and Bangladeshi women was more than twice that of locals. Indians had the lowest prevalence of diabetes across South Asians, and of CHD across South Asian men, while the prevalence of CHD among Indian women was twice that of local women (2.6% vs. 1.3%). Filipinos had the highest prevalence of hypertension among men (21.8%). Chinese men and women had the lowest prevalence of risk factors and CVD. CONCLUSIONS: In Catalonia, preventive interventions adapted to the risk profile of different Asian immigrant groups are needed, particularly for Bangladeshis and Pakistanis.

RESUMO

BACKGROUND: Financial toxicity (FT) is a well-established side-effect of the high costs associated with cancer care. In recent years, studies have suggested that a significant proportion of those with atherosclerotic cardiovascular disease (ASCVD) experience FT and its consequences. OBJECTIVES: This study aimed to compare FT for individuals with neither ASCVD nor cancer, ASCVD only, cancer only, and both ASCVD and cancer. METHODS: From the National Health Interview Survey, we identified adults with self-reported ASCVD and/or cancer between 2013 and 2018, stratifying results by nonelderly (age <65 years) and elderly (age ≥65 years). We defined FT if any of the following were present: any difficulty paying medical bills, high financial distress, cost-related medication nonadherence, food insecurity, and/or foregone/delayed care due to cost. RESULTS: The prevalence of FT was higher among those with ASCVD when compared with cancer (54% vs. 41%; p < 0.001). When studying the individual components of FT, in adjusted analyses, those with ASCVD had higher odds of any difficulty paying medical bills (odds ratio [OR]: 1.22; 95% confidence interval [CI]: 1.09 to 1.36), inability to pay bills (OR: 1.25; 95% CI: 1.04 to 1.50), cost-related medication nonadherence (OR: 1.28; 95% CI: 1.08 to 1.51), food insecurity (OR: 1.39; 95% CI: 1.17 to 1.64), and foregone/delayed care due to cost (OR: 1.17; 95% CI: 1.01 to 1.36). The presence of ≥3 of these factors was significantly higher among those with ASCVD and those with both ASCVD and cancer when compared with those with cancer (23% vs. 30% vs. 13%, respectively; p < 0.001). These results remained similar in the elderly population. CONCLUSIONS: Our study highlights that FT is greater among patients with ASCVD compared with those with cancer, with the highest burden among those with both conditions.

RESUMO

Tumor-infiltrating lymphocytes (TILs) reflect the host immune response against cancer cells. Immunomodulators have been recently suggested as a novel therapeutic strategy against triple-negative breast cancer (TNBC). However, the TIL profile in TNBC has not been thoroughly investigated. In the present study, the percentage, immunophenotype and genetic profiles of TILs in pre-surgical tumor samples of patients with TNBC were evaluated prior to neoadjuvant chemotherapy (NAC). Patients diagnosed with breast cancer at Hospital San José TecSalud were consecutively and prospectively enrolled in the present study between August 2011 and August 2015. The pathological response to NAC was evaluated using the de Miller-Payne and MD Anderson Cancer Center system. TIL percentage (low, intermediate, and high) was evaluated using special hematoxylin-eosin staining on the core needle biopsies. The immunophenotype of TILs was assessed by immunohistochemistry (IHC) for CD3+, CD4+ and CD8+. In addition, the gene expression profile of CD3, CD4, CD8, CD20, CD45, forkhead box P3, interleukin 6, programmed cell death 1 and CD274 molecule was assessed in all patients. A total of 26 samples from patients with TNBC prior to NAC were included in the present study. TILs were low in 30.7%, intermediate in 38.4% and elevated in 30.7% of tumors. CD3+ and CD4+ counts were associated with the pathological response to NAC (P=0.04). Finally, an overexpression pattern of CD3, CD4, CD8, CD45 and CD20 genes was observed in patients with a partial or complete pathological response. The present results demonstrated that TILs may predict the pathological response to NAC in patients with TNBC. Furthermore, a more accurate association was identified between the high expression levels of CD3, CD4, CD8, CD45 and CD20 genes and partial and complete pathological response, compared with the association between high expression and IHC alone.

RESUMO

BACKGROUND: It is important to study the trends of e-cigarette use among various subgroups to understand which populations may be more susceptible to increased use and, therefore, are at risk for potential long-term health effects. METHODS: We used cross-sectional data from the 2016-2017 Behavioral Risk Factor Surveillance System, a nationally representative U.S. telephone-based survey of adults aged 18 years or older. The 2017 dataset also includes data from participant interviews that had been conducted in the year 2018. Current e-cigarette use was defined as use of e-cigarettes every day or on some days. We analyzed data using survey weights to ensure representativeness of the data to the US population. RESULTS: The study population consisted of 936,319 individuals, of whom 28,917 were current e-cigarette users, and corresponded to 10.8 million U.S. adults. Thirty percent were aged between 18 and 34 years. Forty-nine percent were men; 63% were white, 12% black, and 17% Hispanic. The overall prevalence of current e-cigarette use increased from 4.3% in 2016 to 4.8% in 2018. E-cigarette use significantly increased among middle-aged adults (from 3.9% to 5.2%; P = .004), women (from 3.3% to 4.3%; P <.001), and former smokers (from 5.2% to 7.9%; P = .02), but decreased among current smokers (from 14.5% to 13.8%; P = .02). CONCLUSIONS: In a nationally representative sample, we found important trends in e-cigarette use in a relatively short time frame. A significantly increasing prevalence of e-cigarette use was noted among middle-age adults, women, and former smokers. Our study provides important information about e-cigarette trends that can be used by clinicians when counselling patients and by regulatory agencies to develop public policies.

RESUMO

Casiopeinas are a group of copper-based antineoplastic molecules designed as a less toxic and more therapeutic alternative to cisplatin or Doxorubicin; however, there is scarce evidence about their toxic effects on the whole heart and cardiomyocytes. Given this, rat hearts were perfused with Casiopeinas or Doxorubicin and the effects on mechanical performance, energetics, and mitochondrial function were measured. As well, the effects of Casiopeinas-triggered cell death were explored in isolated cardiomyocytes. Casiopeinas III-Ea, II-gly, and III-ia induced a progressive and sustained inhibition of heart contractile function that was dose- and time-dependent with an IC50 of 1.3 ± 0.2, 5.5 ± 0.5, and 10 ± 0.7 µM, correspondingly. Myocardial oxygen consumption was not modified at their respective IC50, although ATP levels were significantly reduced, indicating energy impairment. Isolated mitochondria from Casiopeinas-treated hearts showed a significant loss of membrane potential and reduction of mitochondrial Ca2+ retention capacity. Interestingly, Cyclosporine A inhibited Casiopeinas-induced mitochondrial Ca2+ release, which suggests the involvement of the mitochondrial permeability transition pore opening. In addition, Casiopeinas reduced the viability of cardiomyocytes and stimulated the activation of caspases 3, 7, and 9, demonstrating a cell death mitochondrial-dependent mechanism. Finally, the early perfusion of Cyclosporine A in isolated hearts decreased Casiopeinas-induced dysfunction with reduction of their toxic effect. Our results suggest that heart cardiotoxicity of Casiopeinas is similar to that of Doxorubicin, involving heart mitochondrial dysfunction, loss of membrane potential, changes in energetic metabolites, and apoptosis triggered by mitochondrial permeability.

RESUMO

BACKGROUND: Atherosclerotic cardiovascular disease (ASCVD) and cancer are among the leading causes of economic burden, morbidity, and mortality in the United States. We aimed to quantify the overall impact of cardiovascular modifiable risk factor (CRF) profile on healthcare expenditures among those with and without ASCVD and/or cancer. METHODS AND RESULTS: The 2012-2013 Medical Expenditure Panel Survey, a nationally representative adult sample (≥40 years), was utilized for the study. Variables included ASCVD, CRF (hypertension, diabetes mellitus, hypercholesterolemia, smoking, physical activity and/or obesity), and cancer (all). Two-part econometric models analyzed cost data. Medical Expenditure Panel Survey participants (n=27 275, 59±9 years, 52% female) were studied and 14% had cancer, translating to 25.6 million US adults over 40 years of age. A higher prevalence of ASCVD was noted in those with versus without cancer (25% versus 14%). Absence of ASCVD and a more favorable CRF profile were associated with significantly lower expenditures across the spectrum of cancer diagnosis. Among cancer patients, the adjusted mean annual cost for those with and without ASCVD were $10 852 (95% confidence interval [8917, 12 788]) and $6436 (95% confidence interval [5531, 7342]). Among cancer patients without ASCVD, adjusted annual healthcare expenditures among those with optimal versus poor CRF profile were $4782 and $7256. CONCLUSIONS: In a nationally representative US adult population, absence of ASCVD and a favorable CRF profile were associated with significantly lower medical expenditure among cancer patients. This provides estimates to continue better cardiovascular management and prevention practices, while contextualizing the burden of cancer.

RESUMO

Background: There is increasing evidence of the role psychosocial factors play as determinants of cardiovascular health (CVH). We examined the association between self-rated health (SRH) and ideal CVH among employees of a large healthcare organization. Methods: Data were collected in 2014 from employees of Baptist Health South Florida during an annual voluntary health risk assessment and wellness fair. SRH was measured using a self-administered questionnaire where responses ranged from poor, fair, good, very good to excellent. A CVH score (the proxy for CVH) that ranged from 0 to 14 was calculated, where 0-8 indicate an inadequate score, 9-10, average and 11-14, optimal. A multinomial logistic regression was used to examine the association between SRH and CVH. Results: Of the 9056 participants, 75% were female and mean age (SD) was 43 ± 12 years. The odds of having a higher CVH score increased as SRH improved. With participants who reported their health status as poor-fair serving as reference, adjusted odds ratios for having an optimal CVH score by the categories of SRH were: excellent, 21.04 (15.08-29.36); very good 10.04 (7.25-13.9); and good 3.63 (2.61-5.05). Conclusion: Favorable SRH was consistently associated with better CVH.

RESUMO

BACKGROUND AND AIMS: Socioeconomic status (SES) has been linked to worse cardiovascular risk factor (CRF) profiles and higher rates of cardiovascular disease (CVD), with an especially high burden of disease for low-income groups. We aimed to describe the trends in prevalence of CRFs among US adults by SES from 2002 to 2013. METHODS: Data from the Medical Expenditure Panel Survey was analyzed. CRFs (obesity, diabetes, hypertension, physical inactivity, smoking and hypercholesterolemia), were ascertained by ICD-9-CM and/or self-report. RESULTS: The proportion of individuals with obesity, diabetes and hypertension increased overall, with low-income groups representing a higher prevalence for each CRF. Of note, physical inactivity had the highest prevalence increase, with the "lowest-income" group observing a relative percent increase of 71.1%. CONCLUSIONS: Disparities in CRF burden continue to increase, across SES groups. Strategies to potentially eliminate the persistent health disparities gap may include a shift to greater coverage for prevention, and efforts to engage in healthy lifestyle behaviors.

RESUMO

BACKGROUND: Despite the progress made to decrease risk factors for cardiovascular diseases, disparities still exist. We examined how education and ethnicity interact to determine disparities in cardiovascular health (CVH) as defined by the American Heart Association. HYPOTHESIS: Education modifies the effect of ethnicity on CVH. METHODS: Individual CVH metrics (smoking, physical activity, body mass index, diet, total cholesterol, blood pressure, and blood glucose) were defined as ideal, intermediate, or poor. Combined scores were categorized as inadequate, average, or optimal CVH. Education was categorized as postgraduate, college, some college, and high school or less; ethnicity was categorized as white, Hispanic, black, and other. Main and interactive associations between education, ethnicity, and the measures of CVH were calculated with multinomial logistic regression. RESULTS: Of 9056 study participants, 74% were women, and mean age was 43 (±12) years. Over half were Hispanic, and two-thirds had at least a college education. With postgraduate education category as the reference, participants with less than a college education were less likely to achieve ideal status for most of the individual CVH metrics, and also less likely to achieve 6 to 7 ideal metrics, and optimal CVH scores. In most of the educational categories, Hispanic participants had the highest proportion with optimal CVH scores and 6 to 7 ideal metrics, whereas black participants had the lowest proportion. However, there were no statistically significant interactions of education and ethnicity for ideal CVH measures. CONCLUSIONS: Higher educational attainment had variable associations with achieved levels of ideal CVH across race/ethnic groups. Interventions to improve CVH should be tailored to meet the needs of target communities.

RESUMO

OBJECTIVE: To examine the association of favorable cardiovascular health (CVH) status with 1-year health care expenditures and resource utilization in a large health care employee population. PARTICIPANTS AND METHODS: Employees of Baptist Health South Florida participated in a health risk assessment from January 1 through September 30, 2014. Information on dietary patterns, physical activity, blood pressure, blood glucose level, total cholesterol level, and smoking were collected. Participants were categorized into CVH profiles using the American Heart Association's ideal CVH construct as optimal (6-7 metrics), moderate (3-5 metrics), and low (0-2 metrics). Two-part econometric models were used to analyze health care expenditures. RESULTS: Of 9097 participants (mean ± SD age, 42.7±12.1 years), 1054 (11.6%) had optimal, 6945 (76.3%) had moderate, and 1098 (12.1%) had low CVH profiles. The mean annual health care expenditures among those with a low CVH profile was $10,104 (95% CI, $8633-$11,576) compared with $5824 (95% CI, $5485-$6164) and $4282 (95% CI, $3639-$4926) in employees with moderate and optimal CVH profiles, respectively. In adjusted analyses, persons with optimal and moderate CVH had a $2021 (95% CI, -$3241 to -$801) and $940 (95% CI, -$1560 to $80) lower mean expenditure, respectively, than those with low CVH. This trend remained even after adjusting for demographic characteristics and comorbid conditions as well as across all demographic subgroups. Similarly, health care resource utilization was significantly lower in those with optimal CVH profiles compared with those with moderate or low CVH profiles. CONCLUSION: Favorable CVH profile is associated with significantly lower total medical expenditures and health care utilization in a large, young, ethnically diverse, and fully insured employee population.
