The effects of reference population size and the availability of information from genotyped ancestors on the accuracy of imputation of single nucleotide polymorphisms (SNP) were investigated for Mexican Holstein cattle. Three scenarios for reference population size were examined: (1) a local population of 2,011 genotyped Mexican Holsteins, (2) animals in scenario 1 plus 866 Holsteins in the US ...

OBJECTIVE This paper reports the first population estimates of prevalence and correlates of personality disorders in the Mexican population. METHOD Personality disorders screening questions from the International Personality Disorder Examination were administered to a representative sample of the Mexican urban adult population (n = 2,362) as part of the Mexican National Comorbidity Survey, va...

The human orosomucoid 1 gene (ORM1) codes an alpha-1-acid glycoprotein that has been classified as an acute-phase reactive protein, and a major drug-binding serum component, as well as an immunomodulatory protein with genetic polymorphisms. Evaluation of ORM variation through isoelectric focusing and immunobloting has revealed a world-wide distribution of the ORM1 F and ORM1 S alleles. We evalu...

BACKGROUND AND PURPOSE We examined the contribution of stroke risk factors to midlife (age 45-59 years) Mexican American and non-Hispanic White ischemic stroke (IS) rate disparities from 2000 to 2010. METHODS Incident IS cases (n=707) and risk factors were identified from the Brain Attack Surveillance in Corpus Christi Project, Nueces County, TX (2000-2010). US Census data (2000-2010) were us...

The accuracy of counts of U.S. racial/ethnic and immigrant groups depends on the coverage of the foreign-born in official data. Because Mexicans constitute by far the largest single national-origin group among the foreign-born in the United States, we compile new evidence about the coverage of the Mexican-born population in the 2000 census and 2001-2010 American Community Survey (ACS) using thr...

INTRODUCTION Recently, multi-ethnic reference ranges for spirometry have been created for use worldwide. In comparison, forced oscillation technique (FOT) reference values are limited to specific equipment and study populations, with current FOT reference ranges created in a Caucasian population. We aimed to develop FOT reference ranges for preschool-aged Mexican children and to compare these w...

Mexican nationals in Mexico City and Mexican Americans in San Antonio, Tex, have a lower adjusted prevalence of hypertension than San Antonio non-Hispanic whites, especially after adjusting for the greater obesity of San Antonio Mexican Americans. The concomitant examination of a new study from Spain may better explain the association of genetic and environmental factors with hypertension. Thre...

This article undertakes a multivariate analysis of political participation among Mexican American immigrants. Traditional forms of participation such as registration and voting are not adequate tests of civic engagement for a population including 7 million noncitizens. Rather, this article examines nonelectoral participation including attending a meeting or rally, volunteering for a campaign, o...

This study aims to portray the complex diversity of the Mexican Mestizo population, which represents 98.8% of the entire population of Mexico. We compiled extended haplotype data of the Y chromosome from populations in the Central Valley of Mexico (CVM), which we compared with other Mestizo and parental (Amerindian, European, and African) populations. A complex ancestral relationship was found ...

The estrogen receptor gene (ER alpha) has been implicated in the development of osteoporosis. In this study, the association of two ER alpha gene polymorphic markers (a TA dinucleotide repeat and a single nucleotide polymorphism, G2014A) with osteoporosis was tested in 70 osteoporotic women, 70 non-osteoporotic women and 500 subjects from the Mexican population. According to the genetic analysi...
