RESUMO
Spinocerebellar ataxias (SCAs) comprise a heterogeneous group of autosomal dominant disorders. The relative frequency of the different SCA subtypes varies broadly among different geographical and ethnic groups as result of genetic drifts. This review aims to provide an update regarding SCA founders in the American continents and the Caribbean as well as to discuss characteristics of these populations. Clusters of SCAs were detected in Eastern regions of Cuba for SCA2, in South Brazil for SCA3/MJD, and in Southeast regions of Mexico for SCA7. Prevalence rates were obtained and reached 154 (municipality of Báguano, Cuba), 166 (General Câmara, Brazil), and 423 (Tlaltetela, Mexico) patients/100,000 for SCA2, SCA3/MJD, and SCA7, respectively. In contrast, the scattered families with spinocerebellar ataxia type 10 (SCA10) reported all over North and South Americas have been associated to a common Native American ancestry that may have risen in East Asia and migrated to Americas 10,000 to 20,000 years ago. The comprehensive review showed that for each of these SCAs corresponded at least the development of one study group with a large production of scientific evidence often generalizable to all carriers of these conditions. Clusters of SCA populations in the American continents and the Caribbean provide unusual opportunity to gain insights into clinical and genetic characteristics of these disorders. Furthermore, the presence of large populations of patients living close to study centers can favor the development of meaningful clinical trials, which will impact on therapies and on quality of life of SCA carriers worldwide.

Ethnic groups can display differential genetic susceptibility to infectious diseases. The arthropod-born viral dengue disease is one such disease, with empirical and limited genetic evidence showing that African ancestry may be protective against the haemorrhagic phenotype. Global ancestry analysis based on high-throughput genotyping in admixed populations can be used to test this hypothesis, while admixture mapping can map candidate protective genes. A Cuban dengue fever cohort was genotyped using a 2.5 million SNP chip. Global ancestry was ascertained through ADMIXTURE and used in a fine-matched corrected association study, while local ancestry was inferred by the RFMix algorithm. The expression of candidate genes was evaluated by RT-PCR in a Cuban dengue patient cohort and gene set enrichment analysis was performed in a Thai dengue transcriptome. OSBPL10 and RXRA candidate genes were identified, with most significant SNPs placed in inferred weak enhancers, promoters and lncRNAs. OSBPL10 had significantly lower expression in Africans than Europeans, while for RXRA several SNPs may differentially regulate its transcription between Africans and Europeans. Their expression was confirmed to change through dengue disease progression in Cuban patients and to vary with disease severity in a Thai transcriptome dataset. These genes interact in the LXR/RXR activation pathway that integrates lipid metabolism and immune functions, being a key player in dengue virus entrance into cells, its replication therein and in cytokine production. Knockdown of OSBPL10 expression in THP-1 cells by two shRNAs followed by DENV2 infection tests led to a significant reduction in DENV replication, being a direct functional proof that the lower OSBPL10 expression profile in Africans protects this ancestry against dengue disease.

The study's objective was to assess temporal changes in birth country and age among newly diagnosed Latino men who have sex with men (MSM). We used records from Hispanics/Latinos (2007-2016) who were reported to the Florida HIV/AIDS surveillance system. We compared trends in birth country/region and age by year using a two-sided Cochran-Armitage Trend Test. Of 12,427 new diagnoses, 85.9% were among men. Of men, 79.5% were MSM. The proportion attributable to MSM increased from 70.0% in 2007-85.7% in 2016 (p-value < .0001). Compared with the trend in the proportion of MSM cases born in US-mainland, the proportion born in Cuba (20.0-29.9%; p-value < .0001) and South America (13.8% to 23.2%; p-value < .0001) increased significantly over time, and the proportion born in Central America (8.1% to 4.5%; p-value < .0001) decreased significantly over time. Compared with the trend in the proportion of MSM aged 35-49 years, the proportion aged 13-24 (15.4% to 20.6%; p-value < .0001) and 25-34 (25.0% to 35.6%; p-value < .0001) years increased significantly over time. In Florida, HIV prevention and screening strategies should be enhanced for Cuban and South American immigrants and young Latinos to address the increasing trend in new diagnoses among Latino MSM.

BACKGROUND: Through its influence on social interactions, simpatía may have a wide-ranging influence on Latinx health. Simpatía-which does not have a direct English translation-refers to being perceived as likeable, pleasant, and easygoing. Research to investigate the influence simpatía on Latinx health is limited, likely due to a lack of options for measuring simpatía among diverse Latinx populations. OBJECTIVES: The goal of this research was to develop a bilingual, survey-based simpatía scale for use among ethnically diverse Latinx adults in health-related settings. METHODS: Data were obtained through a telephone survey data of 1,296 Mexican American, Puerto Rican, and Cuban American adults living in the United States. Interviews were conducted in English and Spanish. Exploratory factor analysis, item response theory analysis, confirmatory factor analysis, and computation of estimates of internal consistency reliability were conducted to inform the development of the final simpatía scale. RESULTS: Results indicate that the final, nine-item, simpatía scale has high internal consistency (α = .83) and measurement invariance among Mexican American, Puerto Rican, and Cuban American adults. Two dimensions were identified, as indicated by a perceptions subscale and a behavior subscale. Cuban Americans were found to have the highest simpatía scores, followed by Puerto Ricans and Mexican Americans. DISCUSSION: Culture is often identified as a powerful potential influence on health-related behaviors, but measures are often not available to assess specific cultural traits. By developing a new tool for measuring simpatía, this research advances opportunities for understanding and promoting Latinx health.

BACKGROUND: Minorities have demonstrated an increased risk for type II endometrial cancers, but no data exists about risk among minority subpopulations. Our objective was to evaluate heterogeneity in risk of type II endometrial cancer (EC) histologies across race and Hispanic sub-groups using data from Florida's statewide cancer registry (FCDS). METHODS: FCDS contains data on N=26,416 women diagnosed with EC from 2004 to 2013. Our analysis included women ≥18years of age who were classified as non-Hispanic White (NHW), non-Hispanic Black (NHB) or belonged to one of five Hispanic sub-groups, and had a histology code consistent with type I or type II EC. Binary logistic regression analyses were performed to model risk of type II versus type I ECs across racial and ethnic groups relative to NHW. RESULTS: Relative to NHW, overall odds of being diagnosed with a type II EC were significantly higher in NHB (OR=2.64, 95%CI: 2.38-2.92), Cubans (OR=1.35, 95%CI: 1.08-1.68) and South and Central Americans (SCA) (OR=1.84, 95%CI: 1.40-2.43). Compared to NHW, odds of serous EC were significantly higher in Cubans (OR=2.15, 95% CI: 1.51-3.05) and NHB (OR=2.51, 95% CI: 2.11-2.97); odds of carcinosarcoma (CS) were significantly higher in NHB (OR=2.97, 95% CI: 2.47-3.57) and Puerto Ricans (OR=2.35, 95%CI: 1.32-4.17); and odds of grade III adenocarcinoma (AG3) were significantly higher in NHB (OR=1.60, 95% CI: 1.42-1.81) and SCA (OR=1.76, 95%CI: 1.29-2.40). CONCLUSION: Risk of type II EC varies considerably across Hispanic sub-groups, with Cubans, Puerto Ricans and SCA characterized by elevated odds for specific type II histologies.

Using a nationally representative sample of 2514 U.S. Latinos, this study examined the extent to which major depressive disorder (MDD) onset differs by place of origin and the factors associated with it. The Kaplan-Meier method estimated the survival and hazard functions for MDD onset by place of origin, and Cox proportional hazards models identified its associative factors. Approximately 13% of the sample had experienced MDD in their lifetimes. Cuban respondents showed the highest survival function, while Puerto Ricans showed the lowest. With the entire sample, the smoothed hazard function showed that the risk of MDD onset peaked in the late 20s and early 80s. Puerto Rican respondents showed the highest risk of MDD during their 20s and 30s, whereas Cuban respondents showed a relatively stable pattern over time. The results from the Cox proportional hazards model indicated that age, sex, and marital status were significantly related to MDD onset (p < .05). In addition, the effect of U.S.-born status on MDD onset was greater among Mexican respondents than among Puerto Ricans. Findings from the present study demonstrate that different Latino subgroups experience different and unique patterns of MDD onset over time. Future research should account for the role of immigration status in examining MDD onset.

PURPOSE: In California, colorectal cancer (CRC) is the second most common cancer in Latinos. Using data from the California Cancer Registry, we investigated demographic and clinical characteristics of 36,133 Latinos with CRC living in California during 1995-2011 taking into account subpopulations defined by country of origin. METHODS: Cases were defined as Latino according to the North American Association of Central Cancer Registries Hispanic Identification Algorithm, which was also used to group cases by country of origin: Mexico (9,678, 27 %), Central or South America (2,636, 7 %), Cuban (558, 2 %), Puerto Rico (295, 1 %), and other or unknown origin (22,966, 64 %; Other/NOS). 174,710 non-Hispanic white (NHW) CRC cases were included for comparison purposes. Annual age-adjusted incidence rates (AAIR) and proportional incidence ratios (PIRs) were calculated. RESULTS: Differences were observed for age at diagnosis, sex distribution, socioeconomic status (SES), nativity (US born vs. foreign born), stage, and tumor localization across Latino subpopulations and compared to NHW. Mexican Latinos had the lowest AAIR and Cuban Latinos had the highest. PIRs adjusted for age, SES, and nativity showed an excess of CRC males and female cases from Cuba, female cases from Puerto Rico and reduced number of female cases from Mexico. CONCLUSIONS: Differences in cancer incidence patterns and tumor characteristics were observed among Latino subpopulations in California. These disparities may reflect differences in cancer determinants among Latinos; therefore, given that country of origin information is unavailable for a large proportion of these patients, greater efforts to collect these data are warranted.

BACKGROUND: Individual-level measures of acculturation (e.g. age of immigration) have a complex relationship with psychiatric disorders. Fine-grained analyses that tap various acculturation dimensions and population subgroups are needed to generate hypotheses regarding the mechanisms of action for the association between acculturation and mental health. METHOD: Study participants were US Latinos (N = 6359) from Wave 2 of the 2004-2005 National Epidemiologic Survey of Alcohol and Related Conditions (N = 34 653). We used linear χ2 tests and logistic regression models to analyze the association between five acculturation dimensions and presence of 12-month DSM-IV mood/anxiety disorders across Latino subgroups (Mexican, Puerto Rican, Cuban, 'Other Latinos'). RESULTS: Acculturation dimensions associated linearly with past-year presence of mood/anxiety disorders among Mexicans were: (1) younger age of immigration (linear χ2 1 = 11.04, p < 0.001), (2) longer time in the United States (linear χ2 1 = 10.52, p < 0.01), (3) greater English-language orientation (linear χ2 1 = 14.57, p < 0.001), (4) lower Latino composition of social network (linear χ2 1 = 15.03, p < 0.001), and (5) lower Latino ethnic identification (linear χ2 1 = 7.29, p < 0.01). However, the associations were less consistent among Cubans and Other Latinos, and no associations with acculturation were found among Puerto Ricans. CONCLUSIONS: The relationship between different acculturation dimensions and 12-month mood/anxiety disorder varies across ethnic subgroups characterized by cultural and historical differences. The association between acculturation measures and disorder may depend on the extent to which they index protective or pathogenic adaptation pathways (e.g. loss of family support) across population subgroups preceding and/or following immigration. Future research should incorporate direct measures of maladaptive pathways and their relationship to various acculturation dimensions.

BACKGROUND: Primary cesarean deliveries are a major contributor to the large increase in cesarean delivery rates in the United States over the past 2 decades and are an essential focus for the reduction of related morbidity and costs. Studies have shown that primary cesarean delivery rates among low-risk women in the United States vary 3-fold across hospitals and are not explained by differences in patient case-mix. However, the extent to which maternal vs hospital characteristics contribute to this variation remains poorly understood because previous studies were limited in scope and did not assess the influence of factors such as maternal ethnicity subgroups or prepregnancy obesity. OBJECTIVE: We assessed the contribution of individual- and hospital-level risk factors to the hospital variation in primary cesarean delivery rates among low-risk women in Florida. STUDY DESIGN: Our population-based retrospective cohort study used Florida's linked birth certificate and hospital discharge records for the period of 2004-2011. The study population was comprised of 412,192 nulliparous, singleton, vertex, live births with labor at 37-40 weeks gestation in 122 nonmilitary delivery hospitals. Data were analyzed with logistic mixed-effects regression with cesarean delivery as the outcome. This approach provided adjusted risk estimates at an individual and hospital level and the estimated percent of hospital variation statewide that was explained by these factors. RESULTS: The primary cesarean delivery rate in the study population was 23.9%, with hospital-specific estimates that ranged from 12.8-47.3%. Leading risk factors for cesarean delivery were maternal age ≥35 years (adjusted relative risk, 2.22), prepregnancy obesity (body mass index, ≥30 kg/m(2); adjusted relative risk, 1.73), medical risk conditions (adjusted relative risk, 1.72), labor induction (adjusted relative risk, 1.52), and delivery in hospitals located in Miami-Dade County (adjusted relative risk, 1.73). Hospital geographic location was a significant effect modifier for prepregnancy obesity, medical conditions, and labor induction (P < .05), with a tendency towards lower adjusted relative risks for these factors in Miami-Dade County relative to other Florida regions. Conversely, Miami-Dade County had an increased prevalence of higher-risk ethnic subgroups, such as Cuban or Puerto Rican mothers, and also substantially higher adjusted relative risks that were associated with practice-related factors, such as delivery during weekday hours. Whereas hospital geographic location contributed to 39.6% of the observed variation statewide, the estimated contribution of maternal ethnicity ranged from 1.6-15.7% among Florida regions. CONCLUSIONS: Hospital geographic location contributes to hospital variation in primary cesarean delivery rates among low-risk women in Florida. In contrast to previous studies, our findings suggest that individual level risk factors such as maternal ethnicity also contribute to some of this variation, with differing extent by region. These individual factors likely interact with practice factors and add to the variation. This study was limited by not including maternal Bishop score before induction or obstetrics provider in the analysis. These were not available on the dataset but likely contribute to the variation. Our findings suggest potential issues to consider in quality improvement efforts, such as the need for future qualitative research that focuses on mothers in higher-risk ethnic subgroups and providers in high-rate hospitals, particularly those in Miami-Dade County. These studies may help to identify potential cultural differences in maternal beliefs and expectations for delivery and maternal reasons for differences in obstetrics practices.

BACKGROUND: There has been consistent epidemiological evidence of the association between drinking, alcohol dependence, and depression. However, most of the research has ignored potential diversity across Hispanic national subgroups. This study examines the prevalence of depression and explores its association with volume of drinking, age at first drink, binge drinking, and alcohol dependence across Mexican American, Puerto Rican, Cuban, and South/Central American Hispanic national groups. METHODS: Data from more than 19,000 Hispanic adults were obtained from the 2010 to 2012 National Survey on Drug Use and Health. Survey logistic regression methods were used to test for differences in the relationship between major depressive disorder (MDD) and alcohol consumption across national groups. RESULTS: The prevalence of MDD varied significantly across Hispanic national groups (χ(2) = 67.06, p < 0.001). Puerto Ricans (14%) and Mexican Americans (9%) were most likely to have MDD. Mexican Americans had the highest prevalence of alcohol dependence, volume of consumption, and youngest age at first drink compared to Puerto Ricans, Cuban Americans, and Central/South Americans. Multivariate results suggest that the odds of alcohol dependence were nearly 4 times greater among Hispanics with MDD compared to Hispanics who did not meet the criteria for MDD. Hispanic national origin did not modify the association between MDD and alcohol use. CONCLUSIONS: Although significant differences in the prevalence rates of MDD and alcohol-use measures emerged across Hispanic national groups, there was no evidence that the relationships between these measures were different across Hispanic national groups. Further research should investigate the root causes of these variable MDD prevalence rates to inform detection and intervention efforts targeted toward specific national groups.

Individuals with favorable levels of all readily measured major CVD risk factors (low CV risk) during middle age incur lower cardiovascular morbidity and mortality, lower all-cause mortality, and lower Medicare costs at older ages compared to adults with one or more unfavorable CVD risk factors. Studies on predictors of low CV risk in Hispanics/Latinos have focused solely on Mexican-Americans. The objective of this study was to use data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL; enrolled 2008 to 2011) to assess relationships of nativity and length of residence in the US, a commonly used proxy for acculturation, with low CV risk (not currently smoking; no diabetes; untreated total cholesterol <200mg/dL; untreated blood pressure<120/<80; body mass index <25kg/m(2); and no major ECG abnormalities) in 15,047 Central American, South American, Cuban, Dominican, Mexican, Puerto Rican men and women, and Hispanic/Latino men and women identifying as other or >1 heritage. We also tested whether associations varied by Hispanic/Latino background. Women living in the US<10years were 1.96 (95% confidence interval: 1.37, 2.80) times more likely to be low CV risk than US-born women after adjusting for sociodemographic characteristics, diet, physical activity, and self-reported experiences of ethnic discrimination. Findings varied in men by Hispanic/Latino background, but length of residence was largely unrelated to low CV risk. These findings highlight the role acculturative processes play in shaping cardiovascular health in Hispanics/Latinos.

The links between discrimination and adjustment in U.S. Latino/a immigrant adolescents is an important but understudied phenomenon. We aimed to investigate the longitudinal associations (across 1 year) among discrimination, prosocial behaviors, and depressive symptoms in U.S. Latino immigrant adolescents using two competing models: associations between discrimination and prosocial behaviors via depressive symptoms (mental health strain model), and associations between discrimination and depressive symptoms via prosocial behaviors (prosociality strain model). Participants were 302 Latino/a recent immigrant adolescents (53.3 % boys, M age = 14.51 years at Time 1, SD = .88 years) who completed measures of discrimination, depressive symptoms, and prosocial behaviors at 6-month intervals. The results provided support for both proposed models. The discussion examines the importance of prosocial behaviors in understanding adjustment and effects of discrimination among recently immigrated U.S. Latino adolescents.

OBJECTIVE: Because Hispanic ethnicity in the United States is heterogeneous, the purpose of this study was to determine the epidemiology of peripheral arterial disease (PAD) within U.S. Hispanic/Latino groups defined by national background. METHODS: This analysis included 9648 men and women older than 45 years enrolled in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). The ankle-brachial index (ABI) was computed as the higher of the posterior tibial and dorsalis pedis systolic blood pressures for each leg divided by the higher brachial artery systolic blood pressure. The index ABI was the higher of the two. An ABI ≤0.90 was the criterion for the presence of PAD. RESULTS: The mean age was 56 years, and 55% were female. Overall, the prevalence of an ABI ≤0.90 (PAD), 0.90 to 0.99 (borderline), 1.0 to 1.39 (normal), and ≥1.40 (high) was 5.7%, 19.3%, 72.5%, and 2.6%, respectively. After multivariable adjustment for PAD risk factors and compared with Mexicans, Cubans had a nearly threefold higher odds for PAD (odds ratio, 2.9; 95% confidence interval, 1.9-4.4). The odds of PAD for the other Hispanic/Latino groups ranged from 1.2 to 1.8. Although men had a more than threefold higher odds of an ABI ≥1.40 (3.6; 2.0-6.5), the odds did not differ significantly by Hispanic/Latino background. CONCLUSIONS: Compared with Mexican Americans, all other Hispanic/Latino background groups have a significantly higher odds of having PAD, with the odds being nearly threefold higher among Cubans.

INTRODUCTION: In the present study, we investigated associations among cigarette smoking, smoking cessation treatment, and depressive symptoms in Hispanic/Latino adults. METHODS: The multisite prospective population-based Hispanic Community Health Study/Study of Latinos (HCHS/SOL) enrolled a cohort of Hispanic/Latino adults (aged 18-74) from diverse backgrounds (n = 16,412) in 4U.S. communities (Chicago, San Diego, Miami, and Bronx). Households were selected using a stratified 2-stage probability sampling design and door-to-door recruitment, and sampling weights calibrated to the 2010U.S. Population Census. Hispanic/Latino individuals of Dominican, Central American, South American, Cuban, Mexican, and Puerto Rican background were considered. Cigarette smoking, smoking cessation treatment, and depressive symptoms were measured by self-report. RESULTS: Results indicated that current smokers had greater odds for significant depressive symptoms (CES-D score ≥ 10) than never smokers in all Hispanic background groups [odds ratio (OR) > 1.5]. Depressed persons were not more likely to receive prescribed smoking cessation medications from a doctor (OR = 1.43, 95% CI = 0.98-2.08), take over-the-counter medications (OR = 1.11, 95% CI = 0.75-1.66), or receive psychotherapy (OR = 1.02, 95% CI = 0.57-1.85). CONCLUSIONS: In conclusion, these findings suggest that the positive association between smoking status and depressive symptoms is present in all examined Hispanic/Latino background groups.

PURPOSE: To examine illicit drug use and service utilization patterns of US-born and foreign-born Hispanics in the United States. METHODS: Hispanic respondents 18 years and older in the NESARC were categorized as being of Mexican (n = 3,556), Puerto Rican (n = 785), Cuban (n = 346), Central American (n = 513), or South American (n = 381) origin. We examined lifetime prevalence of drug use and substance abuse treatment utilization patterns for US-born and Hispanic immigrants across subgroups. RESULTS: Lifetime prevalence of drug use was greater among US-born Hispanics than Hispanic immigrants after controlling for age, gender, income, education, urbanicity, parental history of drug use problems and lifetime DSM-IV mood/anxiety disorders. Both US-born and immigrant Hispanic drug users were less likely than non-Hispanic white drug users to have utilized any form of substance abuse treatment (US-born AOR = 0.89, immigrant AOR = 0.64) and more likely to have utilized family or social services (US-born AOR = 1.17, immigrant AOR = 1.19). Compared to US-born Hispanic drug users, Hispanic immigrant drug users were less likely to have used any form of substance abuse treatment (AOR = 0.81) and were more likely to have utilized family or social services (AOR = 1.22). CONCLUSION: Strategies to increase engagement and retention of Hispanic drug users in substance abuse treatment include increasing access to linguistically and culturally competent programs that address unmet family and social needs. Further studies examining differences in drug use and service utilization patterns within Hispanic subgroups are needed.

We followed Latino infants prospectively through age 1 to determine whether maternal foreign-born status conferred a protective advantage against reported and substantiated maltreatment across Hispanic-origin groups, and whether the likelihood an infant was reported or substantiated for maltreatment varied by Hispanic origin. We drew data for all Latino infants born in California between 2000 and 2006 (N = 1,909,155) from population-based birth records linked to child protective services data. We used χ(2) tests to assess distributional differences in covariates and utilized generalized linear models to estimate the adjusted relative risk of report and substantiation in models stratified by nativity. We observed significant health advantages in reported and substantiated maltreatment for infants of foreign-born mothers within every Hispanic-origin group. Risks of report and substantiation among infants of Mexican and Central/South American mothers were consistently lower than Puerto Rican and Cuban mothers despite socioeconomic disadvantage. The presence of disparities among Hispanic-origin groups in child maltreatment report and substantiation during infancy has implications for the health of Latinos across the life course. Further research is warranted to unravel the complex processes underlying observed relationships.

The purpose of this study is to evaluate the preliminary efficacy of a dating violence (DV) prevention program for Cuban American adolescents (JOVEN/YOUTH: Juntos Opuestos a la Violence Entre Novios/Together Against Dating Violence). A randomized-controlled experimental design with a delayed condition was used to evaluate the effects on DV victimization and perpetration (N = 82). Self-administrated assessments were completed at baseline, 1 week, 3 months, and 12 months after the intervention to assess for psychological victimization and perpetration and physical and sexual victimization and perpetration. Effect sizes were estimated, and generalized estimating equations were generated to test intervention effects over time and potential gender interactions. The intervention had medium to strong effects on DV victimization and perpetration for male participants but not for females. However, intervention effects were not statistically significant over time. More research is needed to enhance intervention effects of JOVEN on DV outcomes and to evaluate these effects among a larger and more diverse sample.

The aims of this study were to evaluate the diclofenac metabolism in Hispanics from Cuba and Spain and its relation to ethnicity, CYP2C9 genotypes and environmental factors. Diclofenac hydroxylation capacity (concentration ratios of diclofenac/metabolites in 8-h urine) was studied in 160 Cuban (classified as 76 Cuban-Whites-CWs and 84 Cuban-Mestizos-CMs) and 148 Spaniard (SPs) healthy volunteers. Diclofenac and its main metabolites, 4'-hydroxy (OH), 3'-OH and 5-OH diclofenac, and CYP2C9*2 to *6 and *8 alleles were also determined in 132 and 128 CWs and CMs, respectively. Gender, tobacco, caffeine and ethanol consumption were also evaluated. The mean diclofenac/4'-OH diclofenac ratio was higher in CMs (0.72±0.25) than in CWs (0.64±0.20; P<0.05) and SPs (0.57±0.26; P<0.001). The mean diclofenac/4'-OH diclofenac ratio was higher (P<0.05) in subjects with CYP2C9*1/*3 (0.77±0.19; n=22) and CYP2C9*1/*8 (0.93±0.33; n=4) genotypes than with CYP2C9*1/*1 (0.65±0.24; n=90). Environmental factors did not seem to influence the diclofenac metabolism in these populations. The present findings show for the first time interethnic differences between Hispanic groups in urinary diclofenac/4'-OH diclofenac ratios, and the relevance of CYP2C9*3 and CYP2C9*8 alleles.
