Effect Of Alcohol Consumption On Cognitive Decline Among Mexican Adults, Silvia Mejia-Arango, Ihsan Salloum, Gladys E. Maestre

Research Symposium

Background: Studies on the association between alcohol use and cognitive impairment have yielded controversial results suggesting a reduced risk of dementia in drinkers vs. nondrinkers. We aimed to examine the effect of alcohol use on cognitive trajectories among Mexican adults aged 50 and over.

Methods: Data are from 5,898 cognitively normal individuals (2,512 men and 3,386 women) from the Mexican Health and Aging Study (MHAS) with a mean age of 59 years (50-90 years) at baseline (2001) and followed-up after 11 years (2012). The Cross-Cultural Cognitive Examination was the cognitive battery measuring verbal memory, visual memory, attention, and …

Research Symposium

Backgrounds: Folic acid (FA) and vitamin D supplementation is recommended during pregnancy. Quality nutritional care during pregnancy should include the supplementation of these vitamins. Therefore, the aim of this study was to assess the quality of nutritional care regarding supplementation during pregnancy in primary health care units in six states of Mexico (Estado de México, Oaxaca, Yucatán, Chihuahua, Veracruz and Chiapas).

Methods: A mixed study was conducted. An indicator (formed by two sub-indicators) to assess the quality of nutritional care focused on FA and vitamin D supplementation in pregnancy was developed and validated. To assess the quality of care, a …

The Mex-Cog Cognitive Assessment Battery: Discriminant Analysis Of The Cognitive Performance Profile In Older Adults, Silvia Mejía-Arango, Sara Aguilar-Navarro, Alberto José Mimenza-Alvarado

School of Medicine Publications and Presentations

Objective. To analyze the cognitive profile of a clinical sample using the Mex-Cog cognitive battery and establish which cognitive measures and domains contribute most to group separation.

Materials and methods. A group of 145 older adults previously diagnosed with dementia (n= 47), mild cognitive impairment MCI (n= 47), or as cognitively normal (n= 51) were assessed with the Mex-Cog cognitive battery. Six linear discriminant analyses (LDA) were estimated to compare dementia vs. cognitively normal, MCI vs. cognitively normal, and MCI vs. dementia, using ten individual measures and six cognitive domains. We used a leave-one-out cross-validation procedure to evaluate the predictive …

Comparison Of Knowledge And Diagnostic Practices Relating To Autism Spectrum Disorder Between The United States And Mexico, Maria F. Valdez

Theses and Dissertations

The present study examined and compared the knowledge, screening, and diagnostic practices of health care practitioners from Mexico and the United States of America (U.S.) as they relate to autism spectrum disorder (ASD). The participants included 56 healthcare professionals from U.S. and 16 healthcare professionals from Mexico. Data was collected via an online survey. Overall, participants achieved a mean knowledge accuracy of 0.58 (SD = 0.13). The mean accuracy of knowledge in Mexico was 0.52 (SD = 0.13) and the mean accuracy of knowledge in the U.S. was 0.60 (SD = 0.13). Location, years of experience, patient contact, and comfort …

We investigated the distribution of comorbidities among adult tuberculosis (TB) patients in Chiapas, the poorest Mexican state, with a high presence of indigenous population, and a corridor for migrants from Latin America. Secondary analysis on 5508 new adult TB patients diagnosed between 2010 and 2014 revealed that the most prevalent comorbidities were diabetes mellitus (DM; 19.1%) and undernutrition (14.4%). The prevalence of DM in these TB patients was significantly higher among middle aged (41–64 years) compared with older adults (⩾65 years) (38.6% vs. 23.2%; P < 0.0001). The prevalence of undernutrition was lower among those with DM, and higher in communities with high indigenous presence. Immigrants only comprised 2% of all TB cases, but were more likely to have unfavourable TB treatment outcomes (treatment failure, death and default) when compared with those born in Chiapas (29.5% vs. 11.1%; P < 0.05). Unfavourable TB outcomes were also more prevalent among the TB patients with undernutrition, HIV or older age, but not DM (P < 0.05). Our study in Chiapas illustrates the challenges of other regions worldwide where social (e.g. indigenous origin, poverty, migration) and host factors (DM, undernutrition, HIV, older age) are associated with TB. Further understanding of these critical factors will guide local policy makers and health providers to improve TB management.

Factors Affecting Attitudes Towards Individuals With Schizophrenia: Perceptions Of Mexican American College Students, Valerie Paredes

Theses and Dissertations - UTB/UTPA

This study is designed to examine the effects of acculturation and level of familiarity on stigma of Mexican American college students towards individuals with schizophrenia along the border of Texas and Mexico (N = 223). The area has a history of high levels of disparity in regards to the utilization of mental health services. Data was collected by surveying Mexican American college students through a convenience sample at two separate post-secondary southwestern Hispanic-Serving Institutions (HSIs) along a border community. The instrumentation for the study was composed of a demographic questionnaire, The Acculturation Scale for Mexican-Americans-II (Cuéllar, Arnold, & Maldonado, 1995), …

Spanish/English Language Definitions For Applied Behavior Analysis Terminology, Claudia Arteaga
