Several studies were examined to help answer this question. Results of studies found female Hispanic patients tend to be more sedentary and thus struggle more with obesity, while male Hispanic patients tend to be more at risk due to smoking status and hypercholesterolemia. In addition, psychological distress and chronic stress were more likely to affect the risk for diabetes in men while immigration status was more likely to affect cardiovascular health in women. More studies are needed to fully understand the role of gender on diabetes risk;however, practitioners can utilize known information in order to tailor treatment to male or female Hispanic patients.展开更多

Advanced adenoma was defined as adenoma ≥ 1 cm in size,adenomas with villous histology,high grade dysplasia and/or invasive cancer. Statistical analysis was performed using χ2 statistics and t-test.RESULTS: The median age of the patients was 54 years,64.2% were females. Polyps were observed in 489(30.0%) of patients. Adenoma prevalence was 16.8%(n = 273),advanced adenoma 2.4%(n = 39),and colorectal cancer 0.4%(n = 7). Hyperplastic polyps were seen in 6.6% of the cohort(n = 107). Adenomas predominantly exhibited a proximal colonic distribution(53.7%,n = 144); while hyperplastic polyps were mostly located in the distal colon(70%,n = 75). Among 11.7%(n = 191) patients who underwent screening colonoscopy,the prevalence of colorectal lesions was 21.4% adenoma,2.6% advanced adenoma; and 8.3% hyperplastic polyps.CONCLUSION: Our data showed low colorectal cancer prevalence among Hispanics in the Washington DC area. However,the pre-neoplastic pattern of colonic lesions in Hispanics likely points toward a shift in this population that needs to be monitored closely through large epidemiological studies.展开更多

Each participant completed a comprehensive questionnaire regarding basic demographic information, medical history, medication use, and social and family history including alcohol use. Values of the nonalcoholic fatty liver disease fibrosis score(NFS), FIB4 index, BARD score, and Aspartate aminotransferase to Platelet Ratio Index(APRI) were computed using the blood samples collected within 6 mo of liver ultrasonography from each participant. Hepatic steatosis was determined by ultrasonography. As part of univariable analysis, for continuous variables, comparisons among groups were performed with student-t test, one way analysis of variance, and Mann-Whitney test. Pearson χ2 and the Fisher exact test are used to assess differences in categorical variables. For multivariable analyses, logistic regression analyses were performed to identify characteristics associated with hepatic steatosis. All reported P values are based two-sided tests, and a P value of less than 0.05 was considered to indicate statistical significance.RESULTS: The mean age and body mass index(BMI) of the study participants were 49.1 years and 31.3 kg/m2, respectively. Among them, 65.6% were females, 52% had hepatic steatosis, 49.5% had metabolic syndrome, and 29% had elevated aminotransferases. Based on established cut-offs for diagnostic panels, between 17%-63% of the entire cohort was predicted to have NASH with indeterminate or advanced fibrosis. Participants with hepatic steatosis had significantly higher BMI(32.9 ± 5.6 kg/m2 vs 29.6 ± 6.1 kg/m2, P < 0.001) and higher prevalence rates of elevation of ALT(42.2% vs 14.6%, P < 0.001), elevation of aspartate aminotransferase(38.7% vs 18.9%, P < 0.001), and metabolic syndrome(64.8% vs 33%, P < 0.001) than those without hepatic steatosis. The NFS scores(P = 0.002) and the APRI scores(P = 0.002) were significantly higher in those with steatosis but the scores of the FIB4 index and BARD were similar between the two groups. After adjusting for age, gender and BMI, elevated transaminases, metabolic syndrome and its components, intermediate NFS and APRI scores were associated hepatic steatosis in multivariable analysis. CONCLUSION: The burden of NASH and advanced fibrosis in the Hispanic community in South Texas may be more substantial than predicted from referral clinic studies.展开更多

Data were collected retrospectively, including demographics, comorbidities, liver disease characteristics, tumor parameters, treatment, and survival(OS) outcomes. OS analyses were performed using Kaplan-Meier method.RESULTS One hundred and ninety-five patients with HCC were identified: 80.5% were male, and 22% were age 65 or older. Mean age at HCC diagnosis was 59.7 ± 9.8 years. Sixty-one point five percent of patients had Medicare or Medicaid; 4.1% were uninsured. Compared to African American(31.2%) and White(46.2%) patients, Hispanic patients(22.6%) were more likely to have diabetes(P = 0.0019), hyperlipidemia(P = 0.0001), nonalcoholic steatohepatitis(NASH)(P = 0.0021), end stage renal disease(P = 0.0057), and less likely to have hepatitis C virus(P < 0.0001) or a smoking history(P < 0.0001). Compared to African Americans, Hispanics were more likely to meet criteria for metabolic syndrome(P = 0.0491), had higher median MELD scores(P = 0.0159), ascites(P = 0.008), and encephalopathy(P = 0.0087). Hispanic patients with HCC had shorter OS than the other racial groups(P = 0.020), despite similarities in HCC parameters and treatment. CONCLUSION In conclusion, Hispanic patients with HCC have higher incidence of modifiable metabolic risk factors including NASH, and shorter OS than African American and White patients.展开更多

Amongst other factors such as age, sex, race, genetics, obesity, diabetes etc., hypertension continues to be the leading contributing factor towards stroke. Studies regarding stroke in Hispanics are sparse and inconclusive. Objectives: The objective of the present study is to investigate the potential association between blood pressure elevation and risk of ischemic stroke among the Mexican Hispanic population. Methods: A retrospective data analysis was carried out for a planned case-control study with case-control ratios of 1:2. Mexican Hispanic cases were from the ElPasoStroke database with diagnosed hypertension that had sustained an ischemic stroke (n = 505) and Mexican Hispanics diagnosed with hypertension who were stroke-free as controls from the 2005-2010 NHANES databases (n = 1010). In this analysis, we included subjects who had data on systolic, diastolic or mean arterial blood pressures for cases (327) and controls (772). In cases, blood pressure was determined by the initial admission measurement, and in controls, the first measured blood pressure was used. The unadjusted and adjusted effects of continuous measurements of systolic, diastolic and mean arterial blood pressure on stroke were determined using logistic regression analyses. Subjects were further classified into groups based on prehypertension and hypertension ranges, as established by the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7). Unadjusted and adjusted logistic regression models were also used to determine the effect of categorized blood pressures. Results: Our data indicate that per unit increase in systolic, diastolic or mean arterial blood pressure elevates the odds of stroke among the Mexican Hispanic population. Adjusted analysis of categorized blood pressures showed that mild or moderate/severe high blood pressure significantly associated with odds of stroke. Maintaining and controlling blood pressure at more stringent and lower levels, specifically lowering mean arterial pressure may effectively reduce the odds of ischemic stroke among the Mexican Hispanic population. Conclusion: Elevation of blood pressure increases the odds of stroke among the Mexican Hispanic population. Our results provide new strategies to manage the stroke prevention and health disparity issues among the Mexican Hispanic population.展开更多

We hypothesize that the detrimental effect of acculturation on health outcomes will impact sleep quality among HMD. Design: We performed a population-based random digit dialing telephone survey to determine sleep quality in HMD and NHW. We collected from 3667 subjects, demographics, previous diagnosis of depression or anxiety, past treatment for sleep disorders, the Pittsburgh Sleep Quality Index (PSQI) and the Short Acculturation Scale for Hispanics. Results: The prevalence of poor sleep quality (PSQI > 5) was 64.4% for HMD and 64.3% for NHW (p = 0.93). A prior diagnosis of depression or anxiety was an independent predictor of poor sleep quality in both groups (OR 3.4 and 2.7 for HMD and NHW. Ethnicity was not a predictor of poor sleep quality in HMD or NHW. Acculturation was not a predictor of poor sleep quality in HMD. However, highly acculturated young HMD males had significantly more prevalence of poor sleep quality compared to NHW (64.8% vs. 49.8%, p Conclusion: The absence of sleep quality differences in a large sample of HMD and NHW living in San Diego County is contrary to current data of having poorer sleep quality among Latinos. We found that neither ethnicity nor acculturation were predictors of poor sleep quality in HMD. However, we demonstrated a highly prevalent poor sleep quality among the two ethnic groups. The finding of significantly lower sleep quality in young highly acculturated HMD men may represent the heterogeneity of ethnicity related to sleep. Programs to improve sleep quality in subjects with depression and/or anxiety, and in young highly-acculturated HMD seems warranted.展开更多

Hispanic CRC mortality rates in NM surpass those of overall Hispanics in the US. This study was designed to characterize and understand factors contributing to low CRC screening rates in this border region. Methods: A CRC Knowledge Assessment Survey (KAS) was administered in either English or Spanish to 247 individuals attending community events throughout southern NM. A subset of these individuals completed an online CRC risk assessment survey managed by the National Cancer Institute (NCI). Data analysis tested for significant differences in knowledge, physician-patient CRC interactions, CRC risk level perception, and screening rates across diverse ethnic and age groups. Results: Both CRC knowledge and physician-patient CRC interactions were positively associated with participant screening history. Significant age and ethnic differences for CRC knowledge, physician-patient CRC interactions, and screening history in the NM border sample were also seen. Age-eligible Hispanics (50+) as well as those less than 50 years of age had lower CRC knowledge and were less likely to engage in physician-patient CRC interactions than non-Hispanic Whites (NHWs). The age-eligible Hispanics also reported lower CRC screening rates than their NHW counterparts. Conclusions: Low CRC knowledge and limited physician-patient CRC interactions appear to contribute to low screening rates in this NM population. Expanding education and outreach efforts for this border population are essential to promote early CRC detection and thereby decrease overall CRC mortality rates.展开更多

Objective: The aim of this study is to evaluate the effect of the Mediterranean diet (MED) on the BMI in middle-aged Hispanic women with pre-obesity and obesity in Central Washington State. Design: A prospective study was performed to determine the effect of Mediterranean diet on the BMI of 67 Hispanic women with pre-obesity and obesity between 45 to 65 years of age in Central Washington State. The study was carried out for eight weeks. Dietary adherence was monitored to ensure consistent results. Results: The proportion of Hispanic women who reported a reduction in BMI was 94%, with a decrease in mean BMI after eight weeks of 2.8 (95% CI: 2.5 to 3.0) and P = 0.02, with an odds ratio of 2.6. Multiple linear regression analysis was used to adjust for age, education, physical activity, and smoking. Conclusion: The reduction in BMI demonstrates that the Mediterranean diet can be a promising, culturally appropriate therapy to address the obesity epidemic that is prevalent among Hispanic women.展开更多

In this study, we aimed to compare Caucasian and Caribbean Hispanic postmenopausal American women with respect to these characteristics. Thirty-three Caribbean Hispanics were age-matched to thirty-three Caucasian postmenopausal women. At the lumbar spine, the Hispanic women had significantly lower areal bone mineral density (aBMD). At the radius by high-resolution peripheral quantitative computed tomography (HR-pQCT), there were minimal differences between Hispanic and Caucasian women. At the tibia, Hispanic women had lower trabecular volumetric bone density and trabecular number, and higher trabecular separation. Individual trabecula segmentation (ITS) analyses indicated that at the tibia, Hispanic women not only had significantly lower bone volume fraction, but also had significantly lower rod bone volume fraction, plate trabecular number, rod trabecular number and lower plate-plate, plate-rod and rod-rod junction densities compared to Caucasian women. The differences in bone quantity and quality contributed to lower whole bone stiffness at the radius, and both whole bone and trabecular bone stiffness at the tibia in Hispanic women. In conclusion, Hispanic women had poorer bone mechanical and microarchitectural properties than Caucasian women, especially at the load-bearing distal tibia.展开更多

文摘BACKGROUND Metabolic dysfunction-associated steatotic liver disease(MASLD)and metabolic dysfunction-associated steatohepatitis(MASH)are a growing health burden across a significant portion of the global patient population.However,these conditions seem to have disparate rates and outcomes between different ethnic populations.The combination of MASLD/MASH and type 2 diabetes increases the risk of hepatocellular carcinoma(HCC),and Hispanic patients experience the greatest burden,particularly those in South Texas.AIM To compare outcomes between Hispanic and non-Hispanic patients in the United States,while further focusing on the Hispanic population within Southeast Texas to determine whether the documented disparity in outcomes is a function of geographical circumstance or if there is a more widespread reason that all clinicians must account for in prognostic consideration.METHODS This cohort analysis was conducted with data obtained from TriNetX,LLC(“TriNetX”),a global federated health research network that provides access to deidentified medical records from healthcare organizations worldwide.Two cohort networks were used:University of Texas Medical Branch(UTMB)hospital and the United States national database collective to determine whether disparities were related to geographic regions,like Southeast Texas.RESULTS This study findings revealed Hispanics/Latinos have a statistically significant higher occurrence of HCC,type 2 diabetes mellitus,and liver fibrosis/cirrhosis in both the United States and the UTMB Hispanic/Latino groups.Allcause mortality in Hispanics/Latinos was lower within the United States group and not statistically elevated in the UTMB cohort.CONCLUSION This would appear to support that Hispanic patients in Southeast Texas are not uniquely affected compared to the national Hispanic population.
文摘Studies have shown Hispanic patients are at an increasing risk of developing type 2 diabetes;however, little is known about whether gender plays a role. Several studies were examined to help answer this question. Results of studies found female Hispanic patients tend to be more sedentary and thus struggle more with obesity, while male Hispanic patients tend to be more at risk due to smoking status and hypercholesterolemia. In addition, psychological distress and chronic stress were more likely to affect the risk for diabetes in men while immigration status was more likely to affect cardiovascular health in women. More studies are needed to fully understand the role of gender on diabetes risk;however, practitioners can utilize known information in order to tailor treatment to male or female Hispanic patients.

文摘AIM: To evaluate the prevalence and characteristics of colorectal adenoma and carcinoma in an inner city Hispanic population.METHODS: We reviewed the reports of 1628 Hispanic patients who underwent colonoscopy at Howard University from 2000 to 2010. Advanced adenoma was defined as adenoma ≥ 1 cm in size,adenomas with villous histology,high grade dysplasia and/or invasive cancer. Statistical analysis was performed using χ2 statistics and t-test.RESULTS: The median age of the patients was 54 years,64.2% were females. Polyps were observed in 489(30.0%) of patients. Adenoma prevalence was 16.8%(n = 273),advanced adenoma 2.4%(n = 39),and colorectal cancer 0.4%(n = 7). Hyperplastic polyps were seen in 6.6% of the cohort(n = 107). Adenomas predominantly exhibited a proximal colonic distribution(53.7%,n = 144); while hyperplastic polyps were mostly located in the distal colon(70%,n = 75). Among 11.7%(n = 191) patients who underwent screening colonoscopy,the prevalence of colorectal lesions was 21.4% adenoma,2.6% advanced adenoma; and 8.3% hyperplastic polyps.CONCLUSION: Our data showed low colorectal cancer prevalence among Hispanics in the Washington DC area. However,the pre-neoplastic pattern of colonic lesions in Hispanics likely points toward a shift in this population that needs to be monitored closely through large epidemiological studies.

The NFS scores(P = 0.002) and the APRI scores(P = 0.002) were significantly higher in those with steatosis but the scores of the FIB4 index and BARD were similar between the two groups. After adjusting for age, gender and BMI, elevated transaminases, metabolic syndrome and its components, intermediate NFS and APRI scores were associated hepatic steatosis in multivariable analysis. CONCLUSION: The burden of NASH and advanced fibrosis in the Hispanic community in South Texas may be more substantial than predicted from referral clinic studies.
文摘AIM To compare features of hepatocellular carcinoma(HCC) in Hispanics to those of African Americans and Whites.METHODS Patients treated for HCC at an urban tertiary medical center from 2005 to 2011 were identified from a tumor registry. Data were collected retrospectively, including demographics, comorbidities, liver disease characteristics, tumor parameters, treatment, and survival(OS) outcomes. OS analyses were performed using Kaplan-Meier method.RESULTS One hundred and ninety-five patients with HCC were identified: 80.5% were male, and 22% were age 65 or older. Mean age at HCC diagnosis was 59.7 ± 9.8 years. Sixty-one point five percent of patients had Medicare or Medicaid; 4.1% were uninsured. Compared to African American(31.2%) and White(46.2%) patients, Hispanic patients(22.6%) were more likely to have diabetes(P = 0.0019), hyperlipidemia(P = 0.0001), nonalcoholic steatohepatitis(NASH)(P = 0.0021), end stage renal disease(P = 0.0057), and less likely to have hepatitis C virus(P < 0.0001) or a smoking history(P < 0.0001). Compared to African Americans, Hispanics were more likely to meet criteria for metabolic syndrome(P = 0.0491), had higher median MELD scores(P = 0.0159), ascites(P = 0.008), and encephalopathy(P = 0.0087). Hispanic patients with HCC had shorter OS than the other racial groups(P = 0.020), despite similarities in HCC parameters and treatment. CONCLUSION In conclusion, Hispanic patients with HCC have higher incidence of modifiable metabolic risk factors including NASH, and shorter OS than African American and White patients.
文摘Background: Stroke is the fourth leading cause of death in US. Amongst other factors such as age, sex, race, genetics, obesity, diabetes etc., hypertension continues to be the leading contributing factor towards stroke. Studies regarding stroke in Hispanics are sparse and inconclusive. Objectives: The objective of the present study is to investigate the potential association between blood pressure elevation and risk of ischemic stroke among the Mexican Hispanic population. Methods: A retrospective data analysis was carried out for a planned case-control study with case-control ratios of 1:2. Mexican Hispanic cases were from the ElPasoStroke database with diagnosed hypertension that had sustained an ischemic stroke (n = 505) and Mexican Hispanics diagnosed with hypertension who were stroke-free as controls from the 2005-2010 NHANES databases (n = 1010). In this analysis, we included subjects who had data on systolic, diastolic or mean arterial blood pressures for cases (327) and controls (772). In cases, blood pressure was determined by the initial admission measurement, and in controls, the first measured blood pressure was used. The unadjusted and adjusted effects of continuous measurements of systolic, diastolic and mean arterial blood pressure on stroke were determined using logistic regression analyses. Subjects were further classified into groups based on prehypertension and hypertension ranges, as established by the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7). Unadjusted and adjusted logistic regression models were also used to determine the effect of categorized blood pressures. Results: Our data indicate that per unit increase in systolic, diastolic or mean arterial blood pressure elevates the odds of stroke among the Mexican Hispanic population. Adjusted analysis of categorized blood pressures showed that mild or moderate/severe high blood pressure significantly associated with odds of stroke. Maintaining and controlling blood pressure at more stringent and lower levels, specifically lowering mean arterial pressure may effectively reduce the odds of ischemic stroke among the Mexican Hispanic population. Conclusion: Elevation of blood pressure increases the odds of stroke among the Mexican Hispanic population. Our results provide new strategies to manage the stroke prevention and health disparity issues among the Mexican Hispanic population.
文摘Objectives: To investigate differences in sleep quality between Hispanics of Mexican descent (HMD) and Non-Hispanic Whites (NHW) and evaluate the effect of acculturation to the US lifestyle in sleep health. We hypothesize that the detrimental effect of acculturation on health outcomes will impact sleep quality among HMD. Design: We performed a population-based random digit dialing telephone survey to determine sleep quality in HMD and NHW. We collected from 3667 subjects, demographics, previous diagnosis of depression or anxiety, past treatment for sleep disorders, the Pittsburgh Sleep Quality Index (PSQI) and the Short Acculturation Scale for Hispanics. Results: The prevalence of poor sleep quality (PSQI > 5) was 64.4% for HMD and 64.3% for NHW (p = 0.93). A prior diagnosis of depression or anxiety was an independent predictor of poor sleep quality in both groups (OR 3.4 and 2.7 for HMD and NHW. Ethnicity was not a predictor of poor sleep quality in HMD or NHW. Acculturation was not a predictor of poor sleep quality in HMD. However, highly acculturated young HMD males had significantly more prevalence of poor sleep quality compared to NHW (64.8% vs. 49.8%, p Conclusion: The absence of sleep quality differences in a large sample of HMD and NHW living in San Diego County is contrary to current data of having poorer sleep quality among Latinos. We found that neither ethnicity nor acculturation were predictors of poor sleep quality in HMD. However, we demonstrated a highly prevalent poor sleep quality among the two ethnic groups. The finding of significantly lower sleep quality in young highly acculturated HMD men may represent the heterogeneity of ethnicity related to sleep. Programs to improve sleep quality in subjects with depression and/or anxiety, and in young highly-acculturated HMD seems warranted.
文摘Purpose: Colorectal cancer (CRC) mortality rates in New Mexico (NM) continue to be higher than national rates. Hispanic CRC mortality rates in NM surpass those of overall Hispanics in the US. This study was designed to characterize and understand factors contributing to low CRC screening rates in this border region. Methods: A CRC Knowledge Assessment Survey (KAS) was administered in either English or Spanish to 247 individuals attending community events throughout southern NM. A subset of these individuals completed an online CRC risk assessment survey managed by the National Cancer Institute (NCI). Data analysis tested for significant differences in knowledge, physician-patient CRC interactions, CRC risk level perception, and screening rates across diverse ethnic and age groups. Results: Both CRC knowledge and physician-patient CRC interactions were positively associated with participant screening history. Significant age and ethnic differences for CRC knowledge, physician-patient CRC interactions, and screening history in the NM border sample were also seen. Age-eligible Hispanics (50+) as well as those less than 50 years of age had lower CRC knowledge and were less likely to engage in physician-patient CRC interactions than non-Hispanic Whites (NHWs). The age-eligible Hispanics also reported lower CRC screening rates than their NHW counterparts. Conclusions: Low CRC knowledge and limited physician-patient CRC interactions appear to contribute to low screening rates in this NM population. Expanding education and outreach efforts for this border population are essential to promote early CRC detection and thereby decrease overall CRC mortality rates.
文摘Background: Conclusive evidence has yet to emerge regarding the effectiveness and applicability of the Mediterranean diet on middle-aged Hispanic women, the largest female minority group in the United States who is at-risk of metabolic disorders. Objective: The aim of this study is to evaluate the effect of the Mediterranean diet (MED) on the BMI in middle-aged Hispanic women with pre-obesity and obesity in Central Washington State. Design: A prospective study was performed to determine the effect of Mediterranean diet on the BMI of 67 Hispanic women with pre-obesity and obesity between 45 to 65 years of age in Central Washington State. The study was carried out for eight weeks. Dietary adherence was monitored to ensure consistent results. Results: The proportion of Hispanic women who reported a reduction in BMI was 94%, with a decrease in mean BMI after eight weeks of 2.8 (95% CI: 2.5 to 3.0) and P = 0.02, with an odds ratio of 2.6. Multiple linear regression analysis was used to adjust for age, education, physical activity, and smoking. Conclusion: The reduction in BMI demonstrates that the Mediterranean diet can be a promising, culturally appropriate therapy to address the obesity epidemic that is prevalent among Hispanic women.

文摘Hispanic Americans of Caribbean origin are a fast-growing subset of the US population, but there are no studies on bone density, microstructure and biomechanical integrity in this minority group. In this study, we aimed to compare Caucasian and Caribbean Hispanic postmenopausal American women with respect to these characteristics. Thirty-three Caribbean Hispanics were age-matched to thirty-three Caucasian postmenopausal women. At the lumbar spine, the Hispanic women had significantly lower areal bone mineral density (aBMD). At the radius by high-resolution peripheral quantitative computed tomography (HR-pQCT), there were minimal differences between Hispanic and Caucasian women. At the tibia, Hispanic women had lower trabecular volumetric bone density and trabecular number, and higher trabecular separation. Individual trabecula segmentation (ITS) analyses indicated that at the tibia, Hispanic women not only had significantly lower bone volume fraction, but also had significantly lower rod bone volume fraction, plate trabecular number, rod trabecular number and lower plate-plate, plate-rod and rod-rod junction densities compared to Caucasian women. The differences in bone quantity and quality contributed to lower whole bone stiffness at the radius, and both whole bone and trabecular bone stiffness at the tibia in Hispanic women. In conclusion, Hispanic women had poorer bone mechanical and microarchitectural properties than Caucasian women, especially at the load-bearing distal tibia.
