Objective: The objective of this study is to investigate the association between processed and unprocessed red meat consumption and prostate cancer (PCa) stage in a homogenous Mexican-American population. Methods: This population-based case-control study had a total of 582 participants (287 cases with histologically confirmed adenocarcinoma of the prostate gland and 295 age and ethnicity-matched controls) that were all residing in the Southeast region of Texas from 1998 to 2006. All questionnaire information was collected using a validated data collection instrument. Statistical Analysis: Descriptive analyses included Student's t-test and Pearson's Chi-square tests. Odds ratios and 95% confidence intervals were calculated to quantify the association between nutritional factors and PCa stage. A multivariable model was used for unconditional logistic regression. Results: After adjusting for relevant covariates, those who consume high amounts of processed red meat have a non-significant increased odds of being diagnosed with localized PCa (OR = 1.60 95% CI: 0.85 - 3.03) and total PCa (OR = 1.43 95% CI: 0.81 - 2.52) but not for advanced PCa (OR = 0.91 95% CI: 1.37 - 2.23). Interestingly, high consumption of carbohydrates shows a significant reduction in the odds of being diagnosed with total PCa and advanced PCa (OR = 0.43 95% CI: 0.24 - 0.77; OR = 0.27 95% CI: 0.10 - 0.71, respectively). However, consuming high amounts of energy from protein and fat was shown to increase the odds of being diagnosed with advanced PCa (OR = 4.62 95% CI: 1.69 - 12.59; OR = 2.61 95% CI: 1.04 - 6.58, respectively). Conclusion: Mexican-Americans who consume high amounts of energy from protein and fat had increased odds of being diagnosed with advanced PCa, while high amounts of carbohydrates reduced the odds of being diagnosed with total and advanced PCa.^

Despite advances in effective and long-acting contraceptive methods and the introduction into health care that an initial unplanned pregnancy allows, repeat unplanned pregnancy continues to affect Hispanic adolescents at a rate higher than that of non-Hispanic whites. The current study was undertaken to identify and categorize factors associated with uptake of long acting contraception (implant or intrauterine devices) or consistent use of highly effective methods (injectable DMPA, ring, patch, or pills), among Hispanic/Latina teens who have previously given birth. ^ I searched Ovid Medline, Pubmed, CINAHL, PsychINFO, POPLINE and Scopus, and reference lists for studies in English, ≥1980, of original data from the United States on factors related to initiation, maintenance, or discontinuation of contraceptive methods in postpartum or parenting adolescent females. I then identified articles that specified the inclusion of Hispanics/Latinas in the study population and either reported findings specific to race/ethnicity or used race/ethnicity as an independent variable in analyses of contributing factors. I then extracted data for each study and categorized independent variables as predisposing, enabling, or reinforcing following the PRECEDE model.1 Factors found to be associated with contraception use or non-use were combined to create a logic model of risk. ^ Of 9 eligible studies, one solely addressed initiation; one, initiation and maintenance; two, initiation and discontinuation; three, maintenance; and two, maintenance and discontinuation. There was some overlap in the studies' assessments of maintenance and discontinuation and the author(s) often did not distinguish between the two. Nearly all (k=7) were prospective observational studies with convenience samples and bivariate analyses (k=6). One study was initially a quasi-experimental design but became a prospective cohort due to extremely high attrition. Sociodemographic characteristics and predisposing factors were studied frequently, as were reinforcing factors; enabling factors were discussed infrequently and only in studies involving focus groups or interviews. Due to a paucity of research, a consensus of factors found consistently to influence the contraception behavior of postpartum Latina teens could not be established for the overall population nor for cultural subgroups. Future research is needed that focuses on postpartum/parenting Latina teens, with subgroup identification and differentiation, to determine the prevalent and pertinent predisposing, enabling, and reinforcing factors related to effective contraception initiation and maintenance.^

Childhood obesity is a persistent problem in the U.S., especially among Hispanics. Health complications like hypertension, type II diabetes, and metabolic syndrome (Met-S) are being seen at younger ages, and current screening procedures may be inadequate. This study sought to describe the risk factors for Met-S present in a sample of 106 overweight and obese Hispanic children, aged 5-14 years, participating in Nutrition and Exercise Start Today (NEST), a randomized weight management intervention trial at a rural health clinic in New Braunfels, Texas; and to determine associations between these factors and other clinical and socio-demographic characteristics linked to obesity. Baseline data was analyzed for the prevalence of large waist circumference (WC), elevated blood pressure (BP), high fasting serum glucose and serum triglycerides (TG), and low serum HDL cholesterol, in relationship with selected sample characteristics. Main findings included high baseline prevalence rates of large WC (77%), reduced HDL (57%), and elevated BP (30%). WC was significantly associated with BMI percentile and the serum liver function test alanine aminotransferase (ALT) by Fisher's exact test (p<0.001 and p=0.032, respectively), while there were significant relationships between HDL and both female gender and ALT. BMI percentile and ALT were associated with all sets of Met-S diagnostic criteria examined. BMI percentile also had a strong association (p=0.005) with total number of Met-S risk factors, while ALT had a weaker association (p=0.093). WC is a low-cost, simple measure whose use may improve clinic surveillance for childhood obesity and complications like Met-S. WC, BP, HDL and ALT may be used as part of targeted screening for obesity complications like Met-S, particularly in situations where resources are limited.^

Studies have suggested that acculturation is related to diabetes prevalence and risk factors among immigrant groups in the United States (U.S.), however scant data are available to investigate this relationship among Asian Americans and Asian American subgroups. The objective of this cross-sectional study was to examine the association between length of stay in the U.S. and type 2 diabetes prevalence and its risk factors among Chinese Americans in Houston, Texas. Data were obtained from the 2004-2005 Asian-American Health Needs Assessment in Houston, Texas (N=409 Chinese Americans) for secondary analysis in this study. Diabetes prevalence and risk factors (overweight/obesity and access to medical care) were based on self-report. Descriptive statistics summarized demographic characteristics, diabetes prevalence, and reasons for not seeing a doctor. Logistic regression, using an incremental modeling approach, was used to measure the association between length of stay and diabetes prevalence and related risk factors, while adjusting for the potential confounding factors of age, gender, education level, and income level. Although the prevalence of type 2 diabetes was highest among those living in the U.S. for more than 20 years, there was no significant association between length of stay in the U.S. and diabetes prevalence among these Chinese Americans after adjustment for confounding factors. No association was found between length of stay in the U.S. and overweight/obese status among this population either, after adjusting for confounding factors, too. On the other hand, a longer length of stay was significantly associated with increased health insurance coverage in both unadjusted and adjusted models. The findings of this study suggest that length of stay in the U.S. alone may not be an indicator for diabetes risk among Chinese Americans. Future research should consider alternative models to measure acculturation (e.g., models that reflect acculturation as a multi-dimensional, not uni-dimensional process), which may more accurately depict its effect on diabetes prevalence and related risk factors.^

We formed an academic-community partnership with the Salsa Caliente program to undertake a project to better understand how Latina women with cardiovascular disease (CVD) or at risk of CVD view and understand CVD. This study's research question examines the sociocultural factors that influence and inform Latino women's perceptions and beliefs about CVD. Seven out the eleven participants in the Salsa Caliente program consented to be interviewed. The data was collected through recorded interviews, which were transcribed and then analyzed for common themes found among all the participants' narratives. The content analysis looking into common themes yielded four: 1) increased awareness of CVD, 2) trust in doctor, 3) delay in doctor visits, and 4) awareness of health. Implications for interventions and further research are discussed.^

Background: Once thought to be eradicated, pertussis is now making a steady comeback throughout Texas and the United States. Pertussis can have an effect on all demographics, but infants have the greatest health concern as they suffer the highest case-fatality rate. The objective of this study was to create and report a comprehensive summary of confirmed or probable pertussis cases in a Texas County during the 2008 through 2012 time period.^ Methods: A cross-sectional study design was used to show at risk populations in a Texas county using descriptive statistics of data from probable and confirmed pertussis cases in this Texas County from 2008-2012. Data was collected during routine pertussis investigations conducted by the local health department of this Texas County.^ Results: There was a sharp increase in pertussis cases seen in this county in 2012. Hispanics made up the majority of cases (74.9%) as compared to 12.8% of cases among Whites, 3.1% of cases among Blacks and 9.2% of cases among unknown/other. The population of Hispanics within this county was 58.9%. Almost a quarter of cases (24.2%) in this study were hospitalized. There was no difference identified in the proportion of male sources of exposure (48.9%) as compared to female (51.1%). Household contacts were the main sources of exposure: siblings (29.2%), fathers (14.5%), children (14.6%), and mothers (12.5%).^ Conclusion: Prevention intervention needs to be designed to target vulnerable populations and reduce the effect of this sometimes fatal disease. These results show pertussis proportionally has a greater effect on Hispanics. Additional research needs to be conducted on risk factors such as household crowding and immunization status among Hispanics to identify if ethnicity plays a role in risk of transmission of pertussis. The results were limited due to the large amount of missing data in vaccination history and identification of source of exposure.^

Background: Cancer is the second-leading cause of death in the United States, and Asian Americans/Pacific Islanders are the only racial/ethnic group for which cancer is the leading cause of death. Regular cancer screenings help to identify precancerous lesions and cancer at an earlier stage, when the cancer is more treatable. Ethnic disparities in participation in cancer screenings are also striking, and evidence indicates that Asian Americans may have lower rates of cancer screening participation than other racial/ethnic groups. The Health of Houston Survey 2010 (HHS 2010) is an address-based survey, administered via telephone, website, and mail, of over 5,000 respondents in Houston and Harris County that provides recent data on the health status and needs of the Houston community. HHS 2010 researchers oversampled for Asians and Vietnamese Americans in order to obtain a sample size large enough to obtain statistical power. This dataset provides a unique opportunity to examine the cancer screening behaviors and predictors of Vietnamese and Chinese Americans living in Houston, Texas.^ Methods: This study was a secondary data analysis of HHS 2010 data. The data were analyzed to compare the breast, cervical, and colorectal cancer screening compliance rates of Vietnamese and Chinese Americans with other racial/ethnic groups in Houston, Texas. Key predictors of participation and barriers to cancer screening were identified.^ Results: The results of this study indicate that in Houston, Vietnamese Americans and Asian Americans as a whole have strikingly lower rates of participation in cancer screenings compared to other ethnic groups. Chinese Americans had the highest rate of noncompliance for mammography of all ethnic groups; Asian Americans and Vietnamese Americans also had high rates of noncompliance. Similarly, Vietnamese and Asian Americans had high rates of noncompliance with colorectal cancer screening recommendations. Importantly, Vietnamese, Chinese, and Asian Americans had by far the worst pap test participation, with noncompliance rates more than double that of all other racial/ethnic groups. In general, the findings indicated several key predictors in cancer screening behaviors, including English language proficiency, years lived in the United States, health insurance, college education, and income; however, the significance and patterns of these variables varied by ethnic group as well as cancer site.^ Conclusions: This secondary analysis highlights the disparities in cancer screening participation among Vietnamese, Chinese, and Asian Americans in Houston, Texas and indicate the need to identify Asian Americans as a high-risk group in need of health promotion attention. Barriers to screening and educational needs appear to be specific to each target ethnic group. Thus, health educators and health professionals in Houston must focus on the specific educational needs of the key ethnic groups that make up the Houston population. Further, more ethnic-specific research is needed to examine the health behaviors and needs of Houston's Asian American subgroups.^

En el presente trabajo se articulan una serie de ideas en torno a lo que consideramos algunas de las más destacadas contribuciones del maestro Leopoldo Zea al pensamiento latinoamericano. Contribuciones que por numerosas son difíciles de cuantificar pero que, sin embargo, se las puede ubicar a nuestro criterio en cuatro grandes vertientes: 1. En su producción bibliográfica como expresión fundamental del pensamiento latinoamericano; 2. En la enseñanza a través de la formación de gran número de discípulos con aportes al pensamiento filosófico y a la historia de las ideas en América Latina. Aportes vigentes en las corrientes del pensamiento filosófico universal; 3. En su papel como organizador y difusor de los Estudios de América Latina y el Caribe; 4. En su producción hemerográfica como un gran analista de la política latinoamericana y mundial.

Se analizan las concepciones de Domingo Faustino Sarmiento y José Martí acerca del rol letrado en el programa modernizador de América Latina durante la segunda mitad del siglo XIX. Para ello se adopta como eje la divergente significación de las categorías "civilización/barbarie" en los textos Facundo y Nuestra América. Una nueva lectura de estos textos fundacionales de la historia intelectual latinoamericana permite reconocer aspectos críticos muchas veces olvidados por la reconstrucción del discurso letrado en las actuales corrientes de los estudios latinoamericanos.
