Cross Cultural Studies in Mexico

Determinants, Outcomes & Burden of Diabetes and Cardiovascular Disease among Mexicans and Mexican Americans:  Need for a Public & Private Sector Partnership.

Principal Investigator : Ranjita Misra; Co- Principal Investigator in Mexico: Dr. Roxana Valdes Ramos, UEAM.

Funded by TAMU Conacyt Program

Mexican Americans, the largest minority group in the US, have 2-3 times higher prevalence of type 2 diabetes and higher CVD mortality as compared to non-Hispanic Whites (NHW). The objective of this project was to identify clinical and non-clinical determinants (nutritional, cultural, environmental/lifestyle, and psychosocial) of DM and CV.  The study design was a cross-sectional and cross-cultural study of normoglycemic, pre-diabetics, and diabetic Mexicans and Mexican Americans, matched for age, gender, and body mass index (BMI). The study sites included three cities in the border and interior areas of Texas with large Mexican American population. There were three study sites in Mexico (rural and urban). Since this research will use respondents with different levels of socioeconomic status and acculturation, data collection using face-to-face interviews using bilingual individuals is considered to be the most appropriate method. Data collection will combine face-to-face interviews and clinical data to produce an in-depth understanding of the clinical and non-clinical determinants.

Conceptual and Contextual Factors that Influence Diabetes Outcomes: A Comparative Study of Rural and Urban Mexicans and Mexican Americans.

Principal Investigator; Co-Principal Investigator in Mexico: Dr. Ivonne Bordi, UAEM and Dr. Roxana Valdes Ramos, UEAM.

Funded by the Programa de Investigacion de Migracion y Salud (PIMSA), the California-Mexico Health Initiative, University of California Office of the President.

The objective of this study was to examine social, contextual, and individual factors that influence self-care management, and short- and long-term diabetes outcomes in Mexicans and Mexican Americans. The sample size comprised of 151 Rural and Urban Mexicans (76% female, 24% male) in El Oro and Toluca City in Mexico and 108 Mexican Americans (78% female, 22% male) in Laredo, McAllen, and Bryan/College Station Texas.  Data collection was done through face-to-face interviews by ethnically similar interviewers. Serum samples were analyzed for fasting blood glucose, A1c, and lipid profile, and novel CVD risk factors (adiponectin, leptin, and C-Reactive Protein) at St. Joseph laboratory, Diabetes Diagnostic Lab, and Dr. Riechman’s lab at Texas A&M University.

Assessment of Health Literacy for Improved Diabetes Self-Management and Outcomes: A Bi-National Comparison of Mexicans and Mexican-Americans.

Principal Investigators:  Ranjita Misra (TAMU) and Dr. Roxana Valdes Ramos (UAEM).

Funded by Texas A&M University CONACYT Grant

The purpose of our proposed bi-national (cross-sectional) study is to (1) assess health literacy, and (2) determine the association between health literacy, English or Spanish language proficiency, diabetes self-management behaviors, and outcome (blood glucose and blood pressure) among acculturated and unacculturated Mexican Americans in Texas and Mexicans in Mexico. We will compare adults with diabetes in urban and rural Mexico (Coatepec Harinas, Ixtapan de la Sal, Villa Guerrero, Tonatico, and San Andrés Cuextotitlan) and Mexican Americans in the border (Laredo) and interior areas of Texas (Bryan/College Station).
