Project description:Background: This study examined the differences in the prevalence and clinical features of asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) with identical diagnostic criteria by race and ethnicity in two nationwide cohorts of COPD. Methods: We used data from the Korean COPD Subgroup Study (KOCOSS) and phase I of the US Genetic Epidemiology of COPD (COPDGene) study. We defined ACO by satisfying bronchodilator response (BDR) >15% and 400 ml and/or blood eosinophil count ≥300/μl. Results: The prevalences of ACO according to ethnicity were non-Hispanic white (NHW), 21.4%; African American (AA), 17.4%; and Asian, 23.8%. Asian patients with ACO were older, predominantly male, with fewer symptoms, more severe airflow limitation, and fewer comorbidities than NHW and AA patients. During 1-year follow-up, exacerbations occurred in 28.2, 22.0, and 48.4% of NHW, AA, and Asian patients with ACO, respectively. Compared to patients with non-ACO from the same racial group, the risk for exacerbation was significantly higher in NHW and Asian patients with ACO [adjusted incident rate ratio (aIRR), 1.17; 95% CI, 1.01-1.36, and aIRR, 1.37; 95% CI, 1.09-1.71 for NHW and Asian patients with ACO, respectively]. Inhaled corticosteroid (ICS) reduced the risk for future exacerbation in total patients with ACO but the effect was not significant in each racial group. Conclusions: The prevalence of ACO was similar in the two cohorts using the same diagnostic criteria. The risk for future exacerbation was significantly higher in ACO, and the use of ICS reduced the risk for exacerbation in total patients with ACO.

Project description:We investigated early childhood disparities in high body mass index (BMI) between Black and White US children.We compared differences in Black and White children's prevalence of sociodemographic, prenatal, perinatal, and early life risk and protective factors; fit logistic regression models predicting high BMI (? 95th percentile) at age 4 to 5 years to 2 nationally representative samples followed from birth; and performed separate and pooled-survey estimations of these models.After adjustment for sample design-related variables, models predicting high BMI in the 2 samples were statistically indistinguishable. In the pooled-survey models, Black children's odds of high BMI were 59% higher than White children's (odds ratio [OR] = 1.59; 95% confidence interval [CI]= 1.32, 1.92). Sociodemographic predictors reduced the racial disparity to 46% (OR = 1.46; 95% CI = 1.17, 1.81). Prenatal, perinatal, and early life predictors reduced the disparity to nonsignificance (OR = 1.18; 95% CI = 0.93, 1.49). Maternal prepregnancy obesity and short-duration or no breastfeeding were among predictors for which racial differences in children's exposures most disadvantaged Black children.Racial disparities in early childhood high BMI were largely explained by potentially modifiable risk and protective factors.

Project description:Little is known about longitudinal change in physical functioning of older African American/Black and White HIV-infected persons. We examined up to 10 years of data on African American (N = 1,157) and White (N = 400) men with HIV infection and comparable HIV-negative men (n = 1,137 and 530, respectively), age 50-91 years from the Veterans Aging Cohort Study Survey sample. Physical functioning was assessed using the SF-12 (12-Item Short Form Health Survey) physical component summary (PCS) score. Mixed-effects models examined association of demographics, health conditions, health behaviors, and selected interactions with PCS score; HIV biomarkers were evaluated for HIV-infected persons. PCS scores were approximately one standard deviation below that of the general U.S. population of similar age. Across the four HIV/race groups, over time and through ages 65-75 years, PCS scores were maintained; differences were not clinically significant. PCS score was not associated with race or with interactions among age, race, and HIV status. CD4 and viral load counts of African American and White HIV-infected men were similar. Older age, low socioeconomic status, chronic health conditions and depression, lower body mass index, and smoking were associated with poorer PCS score in both groups. Exercising and, counterintuitively, being HIV infected were associated with better PCS score. Among these older African American and White male veterans, neither race nor HIV status was associated with PCS score, which remained relatively stable over time. Chronic disease, depression, and lack of exercise were associated with lower PCS score. To maintain independence in this population, attention should be paid to controlling chronic conditions, and emphasizing good health behaviors.

Project description:BackgroundSignificant racial/ethnic disparities in unintended pregnancy persist in the United States, with the highest rates observed among low-income black and Hispanic women. Differences in contraceptive preferences, beliefs, and self-efficacy may be instrumental in understanding contraceptive behaviors that underlie higher rates of unintended pregnancy among racial/ethnic minorities.ObjectivesOur objective was to understand how contraceptive preferences, beliefs, and self-efficacy vary by race and ethnicity among women veterans.Study designWe analyzed data from the Examining Contraceptive Use and Unmet Need Study, a national telephone survey of women veterans aged 18-44 years who had received primary care at the Veterans Administration in the prior 12 months. Participants rated the importance of various contraceptive characteristics and described their level of agreement with contraceptive beliefs using Likert scales. Contraceptive self-efficacy was assessed by asking participants to rate their certainty that they could use contraception consistently and as indicated over time using a Likert scale. Multivariable logistic regression was used to examine associations between race/ethnicity and contraceptive attitudes, controlling for age, marital status, education, income, religion, parity, deployment history, and history of medical and mental health conditions.ResultsAmong the 2302 women veterans who completed a survey, 52% were non-Hispanic white, 29% were non-Hispanic black, and 12% were Hispanic. In adjusted analyses, compared with whites, blacks had lower odds of considering contraceptive effectiveness extremely important (adjusted odds ratio; 0.55, 95% confidence interval, 0.40-0.74) and higher odds of considering the categories of does not contain any hormones and prevents sexually transmitted infections extremely important (adjusted odds ratio, 1.94, 95% confidence interval, 1.56-2.41, and adjusted odds ratio; 1.99, 95% confidence interval, 1.57-2.51, respectively). Hispanics also had higher odds than whites of considering the category of does not contain any hormones and prevents sexually transmitted infections extremely important (adjusted odds ratio, 1.72, 95% confidence interval, 1.29-2.28, and adjusted odds ratio, 1.63; 95% confidence interval, 1.21-2.19, respectively). Compared with whites, blacks and Hispanics had higher odds of expressing fatalistic beliefs about pregnancy (adjusted odds ratio, 1.79, 95% confidence interval, 1.35-2.39, and adjusted odds ratio, 1.48, 95% confidence interval, 1.01-2.17, respectively); higher odds of viewing contraception as primarily a woman's responsibility (adjusted odds ratio, 1.92, 95% confidence interval, 1.45-2.55, and adjusted odds ratio, 1.77; 95% confidence interval, 1.23-2.54, respectively); and lower odds of being very sure that they could use a contraceptive method as indicated over the course of a year (adjusted odds ratio, 0.73, 95% confidence interval, 0.54-0.98, and adjusted odds ratio, 0.66, 95% confidence interval, 0.46-0.96, respectively).ConclusionWomen veterans' contraceptive preferences, beliefs, and self-efficacy varied by race/ethnicity, which may help explain observed racial/ethnic disparities in contraceptive use and unintended pregnancy. These differences underscore the need to elicit women's individual values and preferences when providing patient-centered contraceptive counseling.

Project description:PurposeRacial/ethnic minoritized groups, women, and economically disadvantaged groups are disproportionately affected by the COVID-19 pandemic. We investigated racial/ethnic differences by gender in correlates of COVID-19 infection among veterans seeking health care services at the Veterans Health Administration. Little is known about gender-specific factors associated with infection among veterans. This study seeks to fill this gap.MethodsThe sample was veterans with results from a COVID-19 test (polymerase chain reaction) conducted at Veterans Health Administration facilities between March 1, 2020, and August 5, 2020, and linked to the Centers for Disease Control and Prevention Social Vulnerability Index data (39,223 women and 316,380 men). Bivariate, multivariate logistic, and predicted probability analyses were conducted. All analyses were stratified by gender.ResultsSimilar percentages of women and men tested positive for COVID-19 (9.6% vs. 10.0%). In multivariate analysis, compared with non-Hispanic White women, American Indian/Alaska Native, Black, and Hispanic women all had significantly higher odds of infection. Similar racial/ethnic differences were found for men. Both older men and women (>40 years) had lower odds of infection, but the age cut points differed (40 for women, 55 for men). Men 80 years and older had a higher odds than those aged less than 40 years of age. For men, but not for women, being employed (vs. unemployed) was associated with an increased odds of infection, and having comorbidities was associated with decreased odds. There were significant differences within and across gender-by-race/ethnicity in infection, after adjusting for covariates.ConclusionsAmerican Indian/Alaska Native, Hispanic, and Black women and men veterans are disproportionately impacted by COVID-19 infection. Widespread testing and tracking, education, and outreach regarding COVID-19 mitigation and vaccination efforts are recommended.

Project description:INTRODUCTION:Non-white minorities are at higher risk for chronic kidney disease than non-Hispanic whites. Better cardiorespiratory fitness is associated with slower declines in estimated glomerular filtration rate and a lower incidence of chronic kidney disease. Little is known regarding associations of fitness with racial disparities in chronic kidney disease. METHODS:A prospective cohort of 3,842 young adults without chronic kidney disease completed a maximal treadmill test at baseline in 1985-1986. Chronic kidney disease status was defined as estimated glomerular filtration rate of <60 mL/min/1.73 m2 during 10-, 15-, 20-, 25-, and 30-year follow-up assessments (through 2006). Analyses were completed in 2019. Multivariable Cox models were used to determine hazard ratios and 95% CI for incidence of chronic kidney disease. Multivariable models included race, gender, age, field center, education, baseline estimated glomerular filtration rate, and time-varying covariates of healthy diet index, smoking status, alcohol intake, BMI, systolic blood pressure, and fasting glucose. Percent attenuation quantified the association of fitness to racial disparities in chronic kidney disease. RESULTS:Chronic kidney disease incidence was higher among blacks (n=83/1,941, 1.61 per 1,000 person years) than whites (43/1,901, 0.82 per 1,000 person years). Every 1-minute shorter treadmill duration was associated with 1.14 (95% CI=1.04, 1.25) times higher risk of chronic kidney disease. Blacks were 1.72 (95% CI=1.13, 2.63) times more likely to develop chronic kidney disease compared with whites. The risk was reduced to 1.54 (95% CI=1.01, 2.39) with fitness added. This suggests that fitness is associated with 20.4% (95% CI=5.8, 43.0%) of the excess risk of chronic kidney disease attributable to race. CONCLUSIONS:Low fitness is a modifiable factor that may contribute to the racial disparity in chronic kidney disease.

Project description:BACKGROUND:Gallbladder diseases are common in Jilin, China. However, there have been few previous studies on this disease. Our study used the chronic disease database in Jilin Province to study the factors correlated with gallbladder diseases. METHODS:A total of 21,435 people were selected from the Jilin Province adult chronic disease survey conducted in 2012. Multistage stratified random cluster sampling was used in this cross-sectional study. Multiple logistic regression analysis was used to explore the independent associations of different factors with gallbladder diseases. RESULTS:There were 1876 people with gallbladder diseases, and the prevalence of the diseases was 8.8% (males 4.4%, females 12.8%). Multivariate logistic regression analysis showed that female (prevalence odds ratio (POR) = 3.13, 95% confidence intervals (CIs): 2.76?3.55), older people (30?45 years (POR = 2.79, 95% CIs: 2.06?3.77), 45?60 years (POR = 4.26, 95% CIs: 3.17?5.73), 60?79 years (POR = 4.72, 95% CIs: 3.48?6.41)), people living in rural areas (POR = 1.65, 95% CIs: 1.49?1.82), smoking (current smoker (POR = 1.15, 95% CIs: 1.01?1.31), former smoker (POR = 1.37, 95% CIs: 1.13?1.66)), high frequency of eating seafood (POR = 0.77, 95% CIs: 0.63?0.93), and high frequency of eating soy products (POR = 0.50, 95% CIs: 0.44?0.58) were associated with gallbladder diseases. CONCLUSIONS:We found that there were some factors associated with gallbladder disease, and there needs to be further studies to confirm these associations.

Project description:The aim of this study was to identify clinical features associated with peripartum cardiomyopathy (PPCM) and possible racial differences and to quantify in-hospital outcomes in delivering mothers with PPCM.Investigation of patient characteristics and outcomes in PPCM has been limited to small cohorts. Hospital discharge data allow assembly of the largest number of PPCM cases to date.Hospital records from 6 states were screened for PPCM. Clinical profiles, maternal, and fetal outcomes in delivering mothers with and without PPCM were compared and stratified by race. A maternal major adverse event (MAE) was defined as death, cardiac arrest, heart transplantation, or mechanical circulatory support. Logistic regression was used to identify variables associated with PPCM.In total, 535 of 4,003,914 records of delivering mothers specified a diagnosis of PPCM. Prevalence of PPCM was highest among African Americans and similar in Caucasians and Hispanics. Established risk factors including age 30 years, African- American race, hypertension, preeclampsia/eclampsia, and multigestational status were associated with PPCM, and novel associations such as anemia and asthma were identified. Autoimmune disease and substance abuse, which can cause cardiomyopathy independently, were also associated with PPCM. Maternal MAE (odds ratio: 436, p < 0.0001) and stillbirth (odds ratio: 3.8, p < 0.0001) occurred more frequently among women with PPCM.The prevalence of PPCM at the time of delivery in Hispanics was similar to Caucasians and lower than African Americans. Autoimmune disease, substance abuse, anemia and asthma were conditions associated with PPCM not consistently identified in smaller cohorts. Peripartum cardiomyopathy was also associated with increased risk of stillbirth and maternal MAEs at delivery.

Project description:BACKGROUND:Racial differences in electrocardiographic (ECG) characteristics and prognostic significance among Whites and Asians are not well described. METHODS AND RESULTS:We studied 2677 White Framingham Heart Study participants (57% women) and 2972 Asian (64% women) Singapore Longitudinal Aging Study participants (mean age 66 years in both) free of myocardial infarction or heart failure. Racial differences in ECG characteristics and effect on mortality were assessed. In linear regression models, PR interval was longer in Asians compared with Whites (multivariable-adjusted ?±SE 5.0±1.4 ms in men and 6.6±0.9 ms in women, both P<0.0006). QT interval was shorter in Asian men (?±SE -6.2±1.2 ms, P<0.0001) and longer in Asian women (?±SE 3.6±0.9 ms, P=0.02) compared to White men and women, respectively. Asians had greater odds of having ECG left ventricular hypertrophy (LVH) compared with Whites (odds ratio [OR] 3.56, 95% confidence interval [CI] 1.36-9.35 for men, OR 1.93, 95% CI 1.35-2.76 for women, both P<0.02). Over a mean follow-up of 11±3 years in Framingham and 8±3 years in Singapore, mortality rates were 24.5 and 13.4 per 1000 person-years among Whites and Asians, respectively. In Cox models, the presence of LVH had a greater effect on all-cause mortality in Asians compared with Whites (hazard ratio [HR] 2.66, 95% CI 1.83-3.88 vs HR 1.30, 95% CI 0.90-1.89, P for interaction=0.02). CONCLUSION:Our findings from two large community-based cohorts show prominent race differences in ECG characteristics between Whites and Asians, and also suggest a differential association with mortality. These differences may carry implications for race-specific ECG reference ranges and cardiovascular risk.

Project description:ObjectiveTo examine black-white and Hispanic-white differences in total knee arthroplasty from 2001 to 2013 in a large cohort of patients diagnosed with osteoarthritis (OA) in the Veterans Affairs (VA) health care system.MethodsData were from the VA Musculoskeletal Disorders cohort, which includes data from electronic health records of more than 5.4 million veterans with musculoskeletal disorders diagnoses. We included white (non-Hispanic), black (non-Hispanic), and Hispanic (any race) veterans, age ≥50 years, with an OA diagnosis from 2001-2011 (n = 539,841). Veterans were followed from their first OA diagnosis until September 30, 2013. As a proxy for increased clinical severity, analyses were also conducted for a subsample restricted to those who saw an orthopedic or rheumatology specialist (n = 148,844). We used Cox proportional hazards regression to examine racial and ethnic differences in total knee arthroplasty by year of OA diagnosis, adjusting for age, sex, body mass index, physical and mental diagnoses, and pain intensity scores.ResultsWe identified 12,087 total knee arthroplasty procedures in a sample of 473,170 white, 50,172 black, and 16,499 Hispanic veterans. In adjusted models examining black-white and Hispanic-white differences by year of OA diagnosis, total knee arthroplasty rates were lower for black than for white veterans diagnosed in all but 2 years. There were no Hispanic-white differences regardless of when diagnosis occurred. These patterns held in the specialty clinic subsample.ConclusionBlack-white differences in total knee arthroplasty appear to be persistent in the VA, even after controlling for potential clinical confounders.
