This report from the Los Angeles site of the NIMH Epidemiologic Catchment Area study reveals significant ethnic and national origin differences in lifetime prevalence rates for three out of six specific, DSM-III-defined anxiety disorders. In the case of simple phobia, United States-born Mexican Americans report higher rates than native non-Hispanic whites or immigrant Mexican Americans, the latter two groups having similar rates. Mexican Americans born in the United States had higher rates of agoraphobia than immigrant Mexican Americans, and non-Hispanic whites reported higher lifetime rates of generalized anxiety disorder compared with both immigrant and native Mexican Americans. Neither ethnic nor national origin differences in lifetime prevalence rates were found for panic disorder, social phobia, and obsessive-compulsive disorder. Selective migration is postulated as a potential factor influencing prevalence differences between native and immigrant Mexican Americans.

A case study of the effects of social experiences on the science identity formation of Mexican American females in high school chemistry

NASA Astrophysics Data System (ADS)

Beeton, Renee P.

Mexican Americans are a rapidly growing ethnic group in the United States. However, they are noticeably absent from physical science fields. Little research has explored the experiences of Mexican American girls in high school chemistry. The theories of identity based on communities of practice and multicultural feminism framed this year-long case study of nine Mexican American girls in a high school chemistry course. This study explored the social encounters and experiences that shaped the participants' identities and how their views of themselves affected their attitudes towards high school chemistry and future science careers. Data collection included a focus group and in-depth interviews with the participants, classroom observations, and teacher interviews. Five main identities influenced the participants' potential to become a scientist: ethnic, gender, science, student, and college. Mexican ethnic identity was the overarching identity; however gender also influenced the participants' other identities. The participants were aware of ethnic gender stereotypes that might hinder them from being successful in science. Also, ethnic factors, such as citizenship and abilities to receive financial aid limited their views of themselves as chemists. Participatory science, student, and school identities were all needed in order for the participants to be potential scientists. Family expectations, authentic relationships with teachers, and personal connections were important factors in the development of these participatory identities.

RT-PCR studies in 93 patients with chronic myelogenous leukemia from the Mexican West were done in order to know the proportion of b2a2 and b3a2 BCR/ABL1 transcripts. Forty-five patients showed the b3a2 transcript (48%), 37 (40%) displayed the b2a2 and in 11 cases (12%) both transcripts were detected. Statistical analyses showed that these figures are in accordance with two of three similar studies realized in Mexican population. Moreover, significant differences were found among Mexican people and patients from other countries, namely Ecuador, England, Italy, Poland, Japan, and Thailand. Ecuadorian patients showed differences with all the populations analyzed. These variations could be due to a different genetic background.

Mobility and International Collaboration: Case of the Mexican Scientific Diaspora.

Marmolejo-Leyva, Rafael; Perez-Angon, Miguel Angel; Russell, Jane M

2015-01-01

We use a data set of Mexican researchers working abroad that are included in the Mexican National System of Researchers (SNI). Our diaspora sample includes 479 researchers, most of them holding postdoctoral positions in mainly seven countries: USA, Great Britain, Germany, France, Spain, Canada and Brazil. Their research output and impact is explored in order to determine their patterns of production, mobility and scientific collaboration as compared with previous studies of the SNI researchers in the periods 1991-2001 and 2003-2009. Our findings confirm that mobility has a strong impact on their international scientific collaboration. We found no substantial influence among the researchers that got their PhD degrees abroad from those trained in Mexican universities. There are significant differences among the areas of knowledge studied: biological sciences, physics and engineering have better production and impact rates than mathematics, geosciences, medicine, agrosciences, chemistry, social sciences and humanities. We found a slight gender difference in research production but Mexican female scientists are underrepresented in our diaspora sample. These findings would have policy implications for the recently established program that will open new academic positions for young Mexican scientists.

The North American Free Trade Agreement (NAFTA) and Mexican Nursing

PubMed Central

2011-01-01

In the context of nurse migration, experts view trade agreements as either vehicles for facilitating migration or as contributing to brain-drain phenomena. Using a case study design, this study explored the effects of the North American Free Trade Agreement (NAFTA) on the development of Mexican nursing. Drawing results from a general thematic analysis of 48 interviews with Mexican nurses and 410 primary and secondary sources, findings show that NAFTA changed the relationship between the State and Mexican nursing. The changed relationship improved the infrastructure capable of producing and monitoring nursing human resources in Mexico. It did not lead to the mass migration of Mexican nurses to the United States and Canada. At the same time, the economic instability provoked by the peso crisis of 1995 slowed the implementation of planned advances. Subsequent neoliberal reforms decreased nurses’ security as workers by minimizing access to full-time positions with benefits, and decreased wages. This article discusses the linkages of these events and the effects on Mexican nurses and the development of the profession. The findings have implications for nursing human resources policy-making and trade in services. PMID:20595330

2014-01-01

Using a sample of 193 Mexican American adolescents (M age at Wave 1 = 14) and three waves of data over two years, this study longitudinally examined the effects of parent-youth acculturation differences, relative to no differences, on parent-adolescent relationship quality and youth problem behavior. We examined parent-youth differences in overall acculturation, Mexican acculturation, and American acculturation. We differentiated between cases in which the adolescent was more acculturated than the parent and cases in which the parent was more acculturated than the adolescent. Adolescents were more commonly similar to their parents than different. Where differences existed, adolescents were not uniformly more American than their parents, no type of difference was associated with parent-adolescent relationship quality, and no type of difference in overall acculturation was associated with youth problem behavior. One type of difference by dimension (adolescent had less Mexican acculturation than mother) was associated with less risk of problem behavior. PMID:27695153

We estimated U.S. and Mexican citizens' willingness to pay (WTP) for protecting habitat for a transborder migratory species, the Mexican free-tailed bat (Tadarida brasiliensis mexicana), using the contingent valuation method. Few contingent valuation surveys have evaluated whether households in one country would pay to protect habitat in another country. This study addresses that gap. In our study, Mexican respondents were asked about their WTP for conservation of Mexican free-tailed bat habitat in Mexico and in the United States. Similarly, U.S. respondents were asked about their WTP for conservation in the United States and in Mexico. U.S. households would pay $30 annually to protect habitat in the United States and $24 annually to protect habitat in Mexico. Mexican households would pay $8 annually to protect habitat in Mexico and $5 annually to protect habitat in the United States. In both countries, these WTP amounts rose significantly for increasing the size of the bat population rather than simply stabilizing the current bat population. The ratio of Mexican household WTP relative to U.S. household WTP is nearly identical to that of Mexican household income relative to U.S. household income. This suggests that the perceived economic benefits received from the bats is similar in Mexico and the United States, and that scaling WTP by relative income in international benefit transfer may be plausible.

Rotavirus is the most common cause of severe diarrhea in infants. The economic costs of treating severe rotavirus can be quite significant and are important to include in any evaluation of prevention programs. The aim of this study was to determine utilization of health care resources and costs incurred due to severe diarrhea associated with rotavirus infection in Mexican children < 5 years of age. The costs of rotavirus infection evaluated in this observational study consisted of hospital, emergency room care and out-patient visit expenses at three hospitals of the Mexican Institute of Social Security throughout 1999-2000. Service costs were estimated from costs of care for rotavirus versus non-rotavirus diarrhea obtained through a follow-up study data of 383 children and administrative records. Diarrhea cases due to rotavirus infection comprised 36% of the sample. Participants with rotavirus diarrhea spent an average of 3.2 days in the hospital, 5.9 hours in the emergency room, and had 1.3 visits to an outpatient physician's office. Some differences in the consumption of health care were found between rotavirus and non-rotavirus diarrhea cases, although the mean costs of rotavirus and nonrotavirus cases were not significantly different. The mean cost per case of severe rotavirus diarrhea was estimated to be US $936. The total cost of treating severe rotavirus diarrhea, including 5,955 rotavirus hospitalizations for 2004, was estimated at US $5.5 million. Health care costs due to treatment for severe rotavirus diarrhea are a significant economic burden to the Mexican Social Security system.

Mexican and Mexican-American children's funds of knowledge as interventions into deficit thinking: opportunities for praxis in science education

NASA Astrophysics Data System (ADS)

Licona, Miguel M.

2013-12-01

In this case study, I use an ethnographic-style approach to understand the funds of knowledge of immigrant families living in colonias on both sides of the US/Mexico border. I focus on how these "knowledges" and concomitant experiences impact the ways we perceive and treat immigrant students who have all too often been viewed through deficit lenses that relegate them to the lowest expectations and outcomes in the classroom. I find that Mexican and Mexican-American families hold unusually sophisticated and relevant "knowledges" to mitigate their everyday lives. In this paper, I will refer to citizens of Mexico, whether they reside in Mexico or have crossed to the United States legally or without documentation for purposes of work, as Mexican. People who have crossed the border and are living in the US as legal residents or have gained citizenship are referred to as Mexican-Americans. They live a hybrid identity that is varied and dynamic, an issue that adds to the complexity of the content and contexts of this study. These families know and use these "knowledges" on a daily basis, yet they are not recognized by teachers in the US as a starting point to affirm and support immigrant children. Instead, immigrant children are relegated to the non-gifted and lower track classes where science is taught from an abstract and non-contextual and therefore less engaged basis. The approach I outline here, based on insights from my case study, can greatly improve teachers' abilities to prepare their curricula for diversity in science education and science literacy as well as for broad expectations for student success.

Odontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample. 753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification. Chi square test was used to establish possible associations ( p <0.05IC95%). From 753 OC, 369 were female and 384 male; 52.9% of them were in their 2nd- 4th decade of life. The most common location (41%) was the mandibular posterior area. Radicular cysts were more frequent in maxillary anterior zone of females ( p 0.0002) at their fourth decade of life. Dentigerous cysts were more frequent in the mandibular posterior zone of males ( p 0.0000) in their second decade of life. Six cases of periodontal lateral cyst; 4 cases of paradental cysts; 4 eruption cysts and 4 cases of adult gingival cyst, as well were identified. Radicular cyst and dentigerous cyst are the most prevalent odontogenic cyst in this Mexican sample. Due to their etiology, dental pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. Therefore, it is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts. Key words: Cyst, dentigerous cyst, mexican, odontogenic cyst, radicular cyst.

Insertion-deletions for human identification purposes (HID-Indels) offer advantages to solve particular forensic situations and complex paternity cases. In Mexico, admixed population known as Mestizos is the largest (∼90%), plus a number of Amerindian groups (∼10%), which have not been studied with HID-Indels. For this reason, allele frequencies and forensic parameters for 38 HID-Indels were estimated in 531 unrelated individuals from one Amerindian (Purépecha) and seven Mestizo populations from different regions of the country. Genotype distribution was in agreement with Hardy-Weinberg expectations in almost all loci/populations. The linkage disequilibrium (LD) test did not reveal possible associations between loci pairs in all eight Mexican populations. The combined power of discrimination was high in all populations (PD >99.99999999998%). However, the power of exclusion of the 38 HID-Indel system (PE >99.6863%) was reduced regarding most of autosomal STR kits. The assessment of genetic structure (AMOVA) and relationships between populations (FST) demonstrated significant differences among Mexican populations, mainly of the Purépecha Amerindian group. Among Mexican-Mestizos, three population clusters consistent with geography were defined: (i) North-West region: Chihuahua, Sinaloa, and Jalisco; (ii) Central-Southern region: Mexico City, Veracruz and Yucatan; (iii) South region: Chiapas. In brief, this report validates the inclusion of the 38 HID-Indel system in forensic casework and paternity cases in seven Mexican-Mestizo populations from different regions, and in one Mexican Amerindian group.

Breast density (BD) is a risk factor for breast cancer. Aims. To describe BD patterns in asymptomatic Mexican women and the pathological mammographic findings. Methods and Material. Prospective, descriptive, and comparative study. Women answered a questionnaire and their mammograms were analyzed according to BI-RADS. Univariate (χ(2)) and conditional logistic regression analyses were performed. Results. In 300 women studied the BD patterns were fat 56.7% (170), fibroglandular 29% (87), heterogeneously dense 5.7% (17), and dense pattern 8.6% (26). Prevalence of fat pattern was significantly different in women under 50 years (37.6%, 44/117) and older than 50 (68.8%, 126/183). Patterns of high breast density (BD) (dense + heterogeneously dense) were observed in 25.6% (30/117) of women ≤50 years and 7.1% (13/183) of women >50. Asymmetry in BD was observed in 22% (66/300). Compression cone ruled out underlying disease in 56 cases. In the remaining 10, biopsy revealed one fibroadenoma, one complex cyst, and 6 invasive and 2 intraductal carcinomas. 2.6% (8/300) of patients had non-palpable carcinomas. Benign lesions were observed in 63.3% (190/300) of cases, vascular calcification in 150 cases (78.9%), and fat necrosis in 38 cases (20%). Conclusions. Mexican women have a low percentage of high-density patterns.

Material and Methods 753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification. Chi square test was used to establish possible associations (p<0.05IC95%). Results From 753 OC, 369 were female and 384 male; 52.9% of them were in their 2nd- 4th decade of life. The most common location (41%) was the mandibular posterior area. Radicular cysts were more frequent in maxillary anterior zone of females (p 0.0002) at their fourth decade of life. Dentigerous cysts were more frequent in the mandibular posterior zone of males (p 0.0000) in their second decade of life. Six cases of periodontal lateral cyst; 4 cases of paradental cysts; 4 eruption cysts and 4 cases of adult gingival cyst, as well were identified. Conclusions Radicular cyst and dentigerous cyst are the most prevalent odontogenic cyst in this Mexican sample. Due to their etiology, dental pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. Therefore, it is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts. Key words:Cyst, dentigerous cyst, mexican, odontogenic cyst, radicular cyst. PMID:28469818

Computerized glow curve deconvolution of thermoluminescent emission from polyminerals of Jamaica Mexican flower

NASA Astrophysics Data System (ADS)

Favalli, A.; Furetta, C.; Zaragoza, E. Cruz; Reyes, A.

The aim of this work is to study the main thermoluminescence (TL) characteristics of the inorganic polyminerals extracted from dehydrated Jamaica flower or roselle (Hibiscus sabdariffa L.) belonging to Malvaceae family of Mexican origin. TL emission properties of the polymineral fraction in powder were studied using the initial rise (IR) method. The complex structure and kinetic parameters of the glow curves have been analysed accurately using the computerized glow curve deconvolution (CGCD) assuming an exponential distribution of trapping levels. The extension of the IR method to the case of a continuous and exponential distribution of traps is reported, such as the derivation of the TL glow curve deconvolution functions for continuous trap distribution. CGCD is performed both in the case of frequency factor, s, temperature independent, and in the case with the s function of temperature.

Hispanics in El Paso, TX, a large American-Mexican border city constitute 85% of the population. Limited cancer research has been conducted in this population. We sought to study the prevalence of BRCA mutations among Hispanic patients of Mexican origin, identify reported Mexican founder or recurrent mutations, and study the breast cancer characteristics in mutation carriers. Hispanic women of Mexican descent with a personal history of breast cancer, who presented consecutively for genetic cancer risk assessment, were enrolled in an Institutional Review Board-approved registry and underwent BRCA testing based on national guidelines. The characteristics of tumors and patients with positive BRCA mutation were analyzed. 88 patients were screened; 18 patients (20%) were BRCA carriers. Among BRCA carriers, 72% were diagnosed with breast cancer at younger than 50 years, 61% had "Triple negative disease". BRCA carriers had a significantly higher Body Mass Index (BMI) than non-carriers. Thirteen patients had BRCA1 mutations and five had BRCA2 mutations. A total of 17 deleterious BRCA Mutations were observed. Seven have been previously reported as specific genes from Mexico as country of origin. Five new mutations in BRCA carriers of Mexican descent were identified. Hispanic breast cancer patients of Mexican origin present at a younger age, and have predominantly triple negative tumors and high BMI. We identified 5 new mutations not reported previously in Hispanic BRCA carriers of Mexican descent. Interestingly, 41% of BRCA mutations identified have been reported as recurrent mutations in Hispanic individuals from Mexico as the country of origin. A more cost-effective approach to initial screening of Hispanic individuals based on country of origin is desirable and would potentially decrease the number of cases requiring complete sequencing.

Rodríguez de Romo, A C

1996-01-01

The history of the rabies in Mexico is a versatile topic because it provides a chance to study different aspects of the history of Mexican science and medicine. This article reconstructs the sequence of events related to rabies vaccination in Mexico. History is also used as a model to study scientific transfer and scientific imperialism, the use of science by politicians in order to validate their governments, and the impact of French medicine on Mexican medicine. In 1888 the physician Eduardo Liceaga, an important political figure, brought the rabies vaccine to Mexico. President Porfirío Diaz supported Liceaga because he assumed that the vaccine was synonymous with modernity, and hence a sign of good government. We also analyze the reasons why there was no Pasteur Institute in Mexico, even though the conditions that allowed its creation in other countries also existed. Two points are of particular interest: 1) Despite its importance, this topic has not formally been studied in the context of the history of Mexican medicine, and 2) A considerable part of the present research is based on original, unpublished manuscripts in French and Mexican archives.

Little is known about the characteristics of acute viral hepatitis cases in the United States (US)-Mexico border region. We analyzed characteristics of acute viral hepatitis cases collected from the Border Infectious Disease Surveillance Project from January 2000-December 2009. Over the study period, 1,437 acute hepatitis A, 311 acute hepatitis B, and 362 acute hepatitis C cases were reported from 5 Mexico and 2 US sites. Mexican hepatitis A cases most frequently reported close personal contact with a known case, whereas, US cases most often reported cross-border travel. Injection drug use was common among Mexican and US acute hepatitis B and C cases. Cross-border travel during the incubation period was common among acute viral hepatitis cases in both countries. Assiduous adherence to vaccination and prevention guidelines in the US is needed and strategic implementation of hepatitis vaccination and prevention programs south of the border should be considered.

Mexican red salsa is one of the most common side dishes in Mexican cuisine. According to data on foodborne illnesses collected by the Centers for Disease Control and Prevention, salsa was associated with 70 foodborne illness outbreaks between 1990 and 2006. Salsa ingredients such as tomatoes, cilantro, and onions often have been implicated in foodborne illness outbreaks. Mexican-style restaurants commonly prepare a large batch of red salsa, store it at refrigeration temperatures, and then serve it at room temperature. Salmonella is one of the top etiologies in foodborne illness outbreaks associated with salsa, and our preliminary studies revealed the consistent presence of Staphylococcus aureus in restaurant salsa. In the present study, we evaluated the survival of Salmonella Enteritidis and S. aureus inoculated into restaurant-made salsa samples stored at ambient (20 degrees C) and refrigeration (4 degrees C) temperatures. These test temperature conditions represent best-case and worst-case scenarios in restaurant operations. Salmonella survived in all samples stored at room temperature, but S. aureus populations significantly decreased after 24 h of storage at room temperature. No enterotoxin was detected in samples inoculated with S. aureus at 6.0 log CFU/g. Both microorganisms survived longer in refrigerated samples than in samples stored at room temperature. Overall, both Salmonella and S. aureus survived a sufficient length of time in salsa to pose a food safety risk.

Physical performance tests play a major role in the geriatric assessment. In particular, gait speed has shown to be useful for predicting adverse outcomes. However, risk factors for slow gait speed (slowness) are not clearly described. To determine risk factors associated with slowness in Mexican older adults. A two-step process was adopted for exploring the antecedent risk factors of slow gait speed. First, the cut-off values for gait speed were determined in a representative sample of Mexican older adults. Then, antecedent risk factors of slow gait speed (defined using the identified cut-points) were explored in a nested, cohort case-control study. One representative sample of a cross-sectional survey for the first step and the Mexican Health and Aging Study (a cohort characterized by a 10-year follow-up). A 4-meter usual gait speed test was conducted. Lowest gender and height-stratified groups were considered as defining slow gait speed. Sociodemographic characteristics, comorbidities, psychological and health-care related variables were explored to find those associated with the subsequent development of slow gait speed. Unadjusted and adjusted logistic regression models were performed. In the final model, age, diabetes, hypertension, and history of fractures were associated with the development of slow gait speed. Early identification of subjects at risk of developing slow gait speed may halt the path to disability due to the robust association of this physical performance test with functional decline.

Objective. There is a lack of information about the genotype frequencies of IL-6 −174G/C and −572G/C polymorphisms in Mexicans with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the association of the IL-6 −174G/C and −572G/C polymorphisms in Mexican mestizo with RA. Methods. We included 137 patients with RA and 102 healthy controls. Patients were assessed for clinical characteristics. IL-6 −174G/C and −572G/C polymorphisms were genotyped using PCR-RFLP analysis. Allele and genotype frequencies and the Hardy-Weinberg equilibrium were computed. Odds ratios (ORs) were computed to identify the risk for RA associated with the presence of GG genotype in comparison with the GC or CC genotypes. Results. The genotype −174GG occurred at a higher frequency in cases and controls (77.4% versus 78.4%, P = 0.845). We found similar results for the genotype −572GG (54% in patients versus 60.8% in controls, P = 0.295). Conclusions. This is the first study to evaluate the association of −174G/C and −572G/C polymorphisms of the IL-6 gene with RA in Mexican mestizo patients. These two polymorphisms were not associated with RA in the studied sample. Additional studies are required to evaluate if these IL-6 polymorphisms have relevance to the development of more severe disease. PMID:24223608

Experiential environmental learning: A case study of innovative pedagogy in Baja Sur, Mexico

NASA Astrophysics Data System (ADS)

Schneller, Andrew Jon

This mixed methods case study describes an innovative two-semester middle school environmental learning course that departs from traditional Mexican expository pedagogy through the incorporation of experiential and service learning. This research takes place in a small middle school in Pescadero, Baja California Sur, Mexico. The research approach utilized in the study adds to the handful of studies in this cross-disciplinary field by employing quantitative methodologies to measure course outcomes on student environmental knowledge, perceptions, and actions, while simultaneously qualitatively describing the behavioral, educational, environmental, and social experiences of students. This research employs Dewey's theories of experience---as well as those of more contemporary authenticity theorists---in order to identify the philosophies that advocate incorporating experiential pedagogy within the curriculum. Implications for Mexican educational policy, practical pedagogical applications, and theory are discussed.

2011-01-01

We know little about Mexican-American (MA) family adaptation to critical events in the informal caregiving experience but, in these days of economic and social turmoil, sons must sometimes step up to provide personal care for their aging mothers. This article compares two empirically real cases of MA males who provided such care, in lieu of a female relative. The cases are selected from a federally-funded, descriptive, longitudinal, mixed methods study of 110 MA caregivers and their care recipients. In case-oriented research, investigators can generate propositions (connected sets of statements) that reflect their findings and conclusions, and can be tested against subsequent cases: Caregiving strain and burden in MA males may have more to do with physical and emotional costs than financial ones; MA males providing personal care for their mothers adopt a matter-of-fact approach as they act “against taboo”; and this approach is a new way to fulfill family obligations.

Studies reporting low prevalence of HPV in OSCC with declining age at presentation are increasing. The aim of this study was to determine the prevalence of HPV in a group of OSCC cases and controls in a Mexican population. The matched case-control study included 80 OSCC cases and 320 controls. HPV/DNA presence was evaluated through PCR amplification using three sets of consensus primers for the L1 gene. A conditional logistic regression analysis was carried out for the matched OSCC cases and controls. Interactions between risk factors and OCSS were tested in the construction process of the models. HPV prevalence was 5% in OSCC cases and 2.5% in controls. HPV-detected types were 16, 18 and 56. According to conditional logistics regression model, an association was detected between HR-HPV and OSCC. All HR-HPV-positive OSCC cases corresponded to young patients (<45 years), non-smokers and non-alcohol drinkers. The HR-HPV can be a contributing factor to oral carcinogenesis, especially in younger individuals without known risk factors such as tobacco and alcohol. © 2013 John Wiley & Sons A/S.

Depression is among the 10 major causes of disability in Mexico. Yet, local contextual factors associated to the disorder remain poorly understood. We measured the impact of several factors on severe depression such as demographics, pharmacotherapy, multimorbidity, and unhealthy behaviors in Mexican teachers. A total of 43,845 Mexican female teachers from 12 Mexican states answered the Patient Health Questionnaire (PHQ9). Data were part the Mexican Teacher's Cohort prospective study, the largest ongoing cohort study in Latin America. Unadjusted and adjusted estimates assessed the impact of several contextual factors between severe versus mild-no depression cases. In total 7026 teachers (16%) had a PHQ9 score compatible with severe depression. From them, only 17% received psychotropics, compared to 60% for those with a formal diagnosis. Less than 5% of teachers with PHQ9 scores compatible with severe depression had a formal diagnosis. Adjusted analysis reported higher odds of pharmacotherapy, having ≥ 3 comorbidities, higher levels of couple, family and work stress, fewer hours of vigorous physical activity, higher alcohol consumption, and smoking as risk factors for severe depression. Also, rural residents of northern and center states appeared more severely depressed compared to their urban counterparts. On average, the PHQ9 scores differed by ~ 10 points between severe and mild-no depressed teachers. A cross-sectional design. Also, the study focused on female teachers between ages 25 and 74 years old, reducing the generalizability of the estimates. Under-diagnosis of clinical depression in Mexican teachers is concerning. Unhealthy behavior is associated with severe depression. The information collected in this study represents an opportunity to build prevention mechanisms of depression in high-risk subgroups of female educators and warrants improving access to mental care in Mexico.

Background: Phyllodes tumor (PT) of the breast in Hispanic patients is more frequently reported with large tumors and with more borderline/malignant subtypes compared with other populations. The objective of this study was to describe characteristics of patients with PT and to identify differences among subtypes in a Mexican population. Methods: A retrospective study was conducted on patients with PT. Sociodemographic, histopathologic, and treatment characteristics were compared among subtypes, including only surgically treated cases due the complete surgical-specimen study requirement for appropriate WHO classification. Results: During 10 years, 346 PT were diagnosed; only 307 were included (305 patients), with a mean age of 41.7 yr. Self-detected lump took place in 91.8%, usually discovered 6 months previously, with median tumor size of 4.5 cm. Local wide excisions were done in 213 (69.8%) and mastectomies in 92 (30.1%). Immediate breast reconstruction took place in 38% and oncoplastic procedures in 23%. PT were classified as benign in 222 (72.3%) cases, borderline in 50 (16.2%), and malignant in 35 (11.4%), with pathological tumor size of 4.2, 5.4, and 8.7 cm, respectively (P<0.001). Patients with malignant PT were older (48 yr), with more diabetics (14.3%), less breastfeeding (37.1%), more smokers (17.1%), with more postmenopausal cases (42.9%), and older age at menopause (51.5 years) compared with the remaining subtypes (P<0.05). Relapse occurred in 8.2% of patients with follow-up. Conclusion: In comparison with other Hispanic publications, these Mexican patients had similar age, with smaller tumors, modestly higher benign PT, fewer malignant PT, and lower documented relapse cases.

An estimated 800,000 people worldwide are occupationally exposed to welding-fumes. Previous studies show that the exposure to such fumes is associated with damage to genetic material and increased cancer risk. In this study, we evaluate the genotoxic effect of welding-fumes using the Micronucleus Test on oral mucosa cells of Mexican welders. We conducted a cross-sectional, matched case-control study of n = 66 (33 exposed welders, and 33 healthy controls). Buccal mucosa smears were collected and stained with acridine orange, observed under 100x optical amplification with a fluorescence lamp, and a single-blinded observer counted the number of micronuclei and other nuclear abnormalities per 2,000 observed cells. We compared the frequencies of micronuclei and other nuclear abnormalities, and fitted generalised linear models to investigate the interactions between nuclear abnormalities and the exposure to welding-fumes, while controlling for smoking and age. Binucleated cells and condensed-chromatin cells showed statistically significant differences between cases and controls. The frequency of micronuclei and the rest of nuclear abnormalities (lobed-nuclei, pyknosis, karyolysis, and karyorrhexis) did not differ significantly between the groups. After adjusting for smoking, the regression results showed that the occurrence of binucleated cells could be predicted by the exposure to welding-fumes plus the presence of tobacco consumption; for the condensed-chromatin cells, our model showed that the exposure to welding-fumes is the only reliable predictor. Our findings suggest that Mexican welders who are occupationally exposed to welding-fumes have increased counts of binucleated and condensed-chromatin cells. Nevertheless, the frequencies of micronuclei and the rest of nuclear abnormalities did not differ between cases and controls. Further studies should shed more light on this subject.

The aim of this study was to evaluate the association of Val66Met brain-derived neurotrophic factor (BDNF) polymorphism with bipolar disorder in (i) a meta-analysis and (ii) a case-control study in a Mexican population. We also investigated the possible association of this polymorphism with clinical features. We performed a keyword search of the PubMed and Web of Science databases. A total of 22 studies that have investigated the association of Val66Met (rs6265) with bipolar disorder were selected for inclusion and combined with random effects meta-analysis, using allelic, additive, dominant, and recessive models. Finally, the single nucleotide polymorphism (rs6265) Val66Met in the BDNF gene was genotyped and compared between 139 patients with bipolar disorder and 141 healthy volunteers in a Mexican population. The pooled results from the meta-analysis (9,349 cases and 7,437 controls) did not show a significant association in any of the models. The same results were obtained in our case-control study when analyzing the distribution of the genotypic frequencies of the Val66Met polymorphism in patients with bipolar disorder. However, when we analyzed the association between rs6265 and lifetime history of suicidal behavior, we found an association between genotype Val-Val and suicide attempt (p = 0.02). Although the present study has some limitations, the results indicate a lack of association between the Val66Met polymorphism and bipolar disorder. However, in our case-control study in a Mexican population, the Val66Met polymorphism was associated with suicidal behavior in patients with bipolar disorder. Nevertheless, it is important to consider potential interactions of the BDNF gene, the environment, and different inheritance patterns, when carrying out future genetic studies with larger samples. © 2014 The Authors.

2011-12-01

Thirteen Trypanosoma cruzi isolates from different geographic regions of Mexico and Guatemala belonging to discrete typing unit (DTU) I and a reference CL-Brener (DTU VI) strain were used to perform enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR). A panel of 57 Mexican serum samples of patients with chronic chagasic cardiopathy and asymptomatic infected subjects (blood bank donors) were used in this study. DNA from the above 14 T. cruzi strains were extracted and analyzed by PCR using different sets of primers designed from minicircle and satellite T. cruzi DNA. The chronic chagasic cardiopathy serum samples were easily recognized with ELISA regardless of the source of antigenic extract used, even with the CL-Brener TcVI, but positive serum samples from blood bank donors in some cases were not recognized by some Mexican antigenic extracts. On the other hand, PCR showed an excellent performance despite the set of primers used, since all Mexican and Guatemalan T. cruzi strains were correctly amplified. In general terms, Mexican, Guatemalan, and CL-Brener T. cruzi strains are equally good sources of antigen when using the ELISA test to detect Mexican serum samples. However, there are some strains with poor performance. The DTU I strains are easily detected using either kinetoplast or satellite DNA target designed from DTU VI strains.

Objectives To compare genotypes of Mycobacterium bovis strains from humans in Southern California with genotypes of M. bovis strains in cattle in Mexico and the USA to explore the possible origins of human infections. Methods We conducted a descriptive analysis of M. bovis genotypes from a binational population of humans and cattle using spacer oligonucleotide typing (spoligotyping). Results One hundred six human M. bovis spoligotypes were compared to spoligotypes from 496 Mexican cattle and 219 US cattle. Twelve spoligotype patterns were identified among human cases and 126 spoligotype patterns were detected in cattle. Over 91% (97/106) of the human M. bovis isolates had spoligotypes that were identical to those found in Mexican cattle. Four human cases had spoligotypes that matched both cattle born in Mexico and in the USA. Nine human cases had spoligotypes that did not match cattle born in Mexico or the USA. Conclusions Our data indicate that the population of M. bovis strains causing human TB disease in Southern California is closely related to the M. bovis strain population found in Mexican cattle and supports existing epidemiological evidence that human M. bovis disease in San Diego likely originated from Mexican cattle.

We seek to examine systematically how well the patterns of initial advantage and deteriorating health apply to immigrants originating from other regions of the world – regions that represent a growing proportion of U.S. immigrants. We begin by identifying which of the groups in our study have a health advantage compared to U.S.-born whites and to Mexican immigrants. We then we assess changes in health over time, controlling for variation in the health profiles of cohorts upon arrival. We use logistic regression of self-rated health and heart conditions with data from the 2004–2013 National Health Interview Survey. The results reveal diversity and similarity in health outcomes across world regions of origin, both on arrival and over time. By comparing and contrasting cases previously examined in isolation, we clarify and qualify theories of the immigrant health paradox and health deterioration. PMID:27544464

Oral health status and the epidemiologic paradox within latino immigrant groups

PubMed Central

2012-01-01

Background According to the United States census, there are 28 categories that define “Hispanic/Latinos.” This paper compares differences in oral health status between Mexican immigrants and other Latino immigrant groups. Methods Derived from a community-based sample (N = 240) in Los Angeles, this cross-sectional study uses an interview covering demographic and behavioral measures, and an intraoral examination using NIDCR epidemiologic criteria. Descriptive, bivariate analysis, and multiple regression analysis were conducted to examine the determinants that are associated with the Oral Health Status Index (OHSI). Results Mexican immigrants had a significantly higher OHSI (p < .05) compared to other Latinos. The multilinear regression showed that both age and gender (p < .05), percentage of untreated decayed teeth (p < .001), number of replaced missing teeth (p < .001), and attachment loss (p < .001) were significant. Conclusions Compared with the other Latino immigrants in our sample, Mexican immigrants have significantly better oral health status. This confirms the epidemiologic paradox previously found in comparisons of Mexicans with whites and African Americans. In this case of oral health status the paradox also occurs between Mexicans and other Latinos. Therefore, when conducting oral health studies of Latinos, more consideration needs to be given to differences within Latino subgroups, such as their country of origin and their unique ethnic and cultural characteristics.

Medical meetings are a tool to help physicians advance and update their medical knowledge. Their quality is the responsibility of colleges and institutions. To assess and compare the academic level of four different annual rheumatology meetings. As a source of information, we used the abstracts published in the supplements of the journal Reumatología Clínica, SE1 Vol. 12, issued in February 2016, SE 1 Vol. 13 issued in February 2017, the electronic application of the 2016 ACR/ARHP of the 2016 American Congress of Rheumatology, devoted to the works presented at the 44th Mexican Congress of Rheumatology (CMR 44), the 45th Mexican Congress of Rheumatology (CMR 45), and the 2016 ACR/ARHP Annual Meeting (ACR 2016), as well as the Web page on the files and abstracts of EULAR 2017, respectively; from each work we compiled information on the major disease being referred to, the type of information provided and the type of report. We should point out that some were combined conditions or designs, from which we selected that which we considered to be the most important. In all, 275, 340, 3275 and 4129 studies were submitted to the XLIV Mexican Congress of Rheumatology, XLV Mexican Congress of Rheumatology, the 2016 ACR/ARHP Annual Meeting and EULAR 2017, respectively. Rheumatoid arthritis was the most common disorder, dealt with in 23%, 26%, 21% and 27% in CMR 44, CMR 45, 2016 ACR and EULAR 2017, respectively, followed by systemic lupus erythematosus; in third place, Mexican congresses reported trials related to systemic vasculitis, whereas spondylitis was the main subject of international congresses. In the case of rheumatoid arthritis, clinical topics accounted for 30% in the Mexican congresses and ACR, and nearly 20% in EULAR. Observational studies accounted for 40% in the Mexican congresses vs. 33% in 2016 ACR and 55% in EULAR 2017. Studies on basic science were minimal in the Mexican congress, whereas in 2016 ACR, they represented 21% and 12% in EULAR 2017. Rheumatology meetings constitute a tool to obtain adequate evidence-based medical knowledge in this important branch of medicine. For our Mexican Congress, we should encourage collaborative efforts between institutions, which will result in a greater number of controlled studies, clinical trials and basic studies that support the quality of the congress. We wish to emphasize that a greater diffusion of other musculoskeletal diseases is needed, not only autoimmune diseases, since the former represent an important percentage of the daily practice.

Giardiosis is a parasitic disease caused by the protozoan Giardia intestinalis, which is distributed worldwide. Most of the data on the prevalence of giardiosis in Mexico comes from research, but it is also necessary to study the data provided by the Mexican Health Ministry and issued by the General Directorate of Epidemiology. The aim of this work was analyse the national surveillance data for human giardiosis in order to update the epidemiological data of this disease in Mexico. A retrospective observational analysis of giardiosis (from January 2011 to December 2015) was performed in the annual reports emitted by the GDE in Mexico. The cases were classified by year, state, age group, gender and seasons of the year. During the period of 2011-2015, a reduction of 38.51% was observed in the total number of new cases of giardiosis reported in the whole country The states of Sinaloa, Yucatan, and Chiapas presented the highest number of new cases reported during the analysed period. Giardiosis rates were always higher among women in all age groups, but the maximum incidence was observed in both sexes in the age group of 1-4 years old (the most susceptible group). On the other hand, the number of cases increased dramatically in southern states during warmer months. Giardiosis is influenced by ambient temperature changes along the year, although this study suggests that tends to decrease in all the analysed states and could be related to the overall improvement of hygienic practices within the Mexican population.

To report two cases of eyeball tattoos with short-term post procedural complications. Case 1 is a 26-year-old Mexican man that developed orbital cellulitis and posterior scleritis 2 h after an eyeball tattoo. Patient responded satisfactorily to systemic antibiotic and corticosteroid treatment. Case 2 is a 17-year-old Mexican man that developed two sub-episcleral nodules in the ink injection sites immediately after the procedure. Eyeball tattoos are performed by non-ophthalmic trained personnel. There are a substantial number of short-term risks associated with this procedure. Long-term effects on the eyes and vision are still unknown, but in a worst case scenario could include loss of vision or permanent damage to the eyes.

Anxiety and depression are considered the most prevalent psychiatric disorders worldwide. In Mexico, the use of medicinal plants to alleviate the symptoms associated with these psychiatric disorders is increasing. However, there is little scientific evidence that validates the efficacy of these plants. This evidence needs to be critically revised, and further studied to provided scientific support for their use. To identify the plants that are used in Mexico for the treatment of disorders related to anxiety and depression, and to review the current preclinical and when available, clinical information of these plants. We searched in scientific databases (Pubmed, Web of Science, Scopus and other web sources such as "Biblioteca digital de la medicina tradicional Mexicana" ) for Mexican plants used for the treatment of anxiety and depression that have been analyzed in preclinical studies. Additional information was obtained from published books. For this review, we also consider those plants used in Mexican traditional medicine for the treatment of "nervios," "susto" or "espanto;" common terms that describe symptoms related to anxiety and depression disorders. The bibliographic search identified 49 plants used in Mexican traditional medicine for the treatment of disorders related to anxiety and depression. From all these plants, 59% were analyzed in preclinical research, and only 8% were tested in clinical studies; only a few of these studies tried to elucidate their mechanism of action. In general, it is proposed that the plant extracts interact with the GABAergic system. However, only part of these studies attempted to analyze other neurotransmitter systems. Finally, in some cases, drug-herbal interactions were reported. There is a large number of Mexican medicinal plants used as a treatment for anxiety and depression disorders. Although some of these plants have been studied in preclinical research, in most cases these studies are preliminary, and the understanding of the mechanism of action is inconclusive. The need for systematic studies in preclinical and clinical research is evident, and efforts should be done to fulfill these research. Finally, it is important also to study possible drug-herbal interactions to establish specific recommendations for people that use these plants as anxiolytic or antidepressant treatments either alone or in combination with another type of medicine.

This study reports the direct costs related to osteoporosis and hip fractures paid for governmental and private institutions in the Mexican health system and estimates the impact of these entities on Mexico. We conclude that the economic burden due to the direct costs of hip fracture justifies wide-scale prevention programs for osteoporosis (OP). To estimate the total direct costs of OP and hip fractures in the Mexican Health care system, a sample of governmental and private institutions were studied. Information was gathered through direct questionnaires in 275 OP patients and 218 hip fracture cases. Additionally, a chart review was conducted and experts' opinions obtained to get accurate protocol scenarios for diagnoses and treatment of OP with no fracture. Microcosting and activity-based costing techniques were used to yield unit costs. The total direct costs for OP and hip fracture were estimated for 2006 based on the projected annual incidence of hip fractures in Mexico. A total of 22,233 hip fracture cases were estimated for 2006 with a total cost to the healthcare system of US$ 97,058,159 for the acute treatment alone ($4,365.50 per case). We found considerable differences in costs and the way the patients were treated across the different health sectors within the country. Costs of the acute treatment of hip fractures in Mexico are high and are expected to increase with the predicted increment of life expectancy and the number of elderly in our population.

To compare genotypes of Mycobacterium bovis strains from humans in Southern California with genotypes of M. bovis strains in cattle in Mexico and the USA to explore the possible origins of human infections. We conducted a descriptive analysis of M. bovis genotypes from a binational population of humans and cattle using spacer oligonucleotide typing (spoligotyping). One hundred six human M. bovis spoligotypes were compared to spoligotypes from 496 Mexican cattle and 219 US cattle. Twelve spoligotype patterns were identified among human cases and 126 spoligotype patterns were detected in cattle. Over 91% (97/106) of the human M. bovis isolates had spoligotypes that were identical to those found in Mexican cattle. Four human cases had spoligotypes that matched both cattle born in Mexico and in the USA. Nine human cases had spoligotypes that did not match cattle born in Mexico or the USA. Our data indicate that the population of M. bovis strains causing human TB disease in Southern California is closely related to the M. bovis strain population found in Mexican cattle and supports existing epidemiological evidence that human M. bovis disease in San Diego likely originated from Mexican cattle.

The Family Investigation of Nephropathy and Diabetes (FIND) is a multicenter study designed to identify genetic determinants of diabetic nephropathy. It is conducted in eight U.S. clinical centers and a coordinating center, and with four ethnic groups (European Americans, African Americans, Mexican Americans, and American Indians). Two strategies are used to localize susceptibility genes: a family-based linkage study and a case-control study using mapping by admixture linkage disequilibrium (MALD). In the family-based study, probands with diabetic nephropathy are recruited with their parents and selected siblings. Linkage analyses will be conducted to identify chromosomal regions containing genes that influence the development of diabetic nephropathy or related quantitative traits such as serum creatinine concentration, urinary albumin excretion, and plasma glucose concentrations. Regions showing evidence of linkage will be examined further with both genetic linkage and association studies to identify genes that influence diabetic nephropathy or related traits. Two types of MALD studies are being done. One is a case-control study of unrelated individuals of Mexican American heritage in which both cases and controls have diabetes, but only the case has nephropathy. The other is a case-control study of African American patients with nephropathy (cases) and their spouses (controls) unaffected by diabetes and nephropathy; offspring are genotyped when available to provide haplotype data. Identification of genes that influence susceptibility to diabetic nephropathy will lead to a better understanding of how nephropathy develops. This should eventually lead to improved treatment and prevention.

To evaluate the implementability of the "2008 Mexican Clinical Practice Guideline for the management of hip and knee osteoarthritis at the primary level of care" within primary healthcare of three Mexican regions using the Guideline Implementability Appraisal methodology version 2 (GLIA.v2). Six family physicians, representing the South, North, and Central Mexico, and one Mexican physiatrist evaluated the 45 recommendations stated by the Mexican guideline. The GLIA.v2 methodology includes the execution of qualitative and semi-quantitative techniques. Reviewers' agreement was between moderate to near complete in most cases. Sixty-nine percent of the recommendations were considered difficult to implement within clinical practice. Eight recommendations did not have an appropriate format. Only 6 recommendations were judged as able to be consistently applied to clinical practice. Barriers related to the context of one or more institutions/regions were identified in 25 recommendations. These barriers are related to health providers/patients' beliefs, processes of care within each institution, and availability of some treatments recommended by the guideline. The guideline presented problems of conciseness and clarity that negatively affect its application within the Mexican primary healthcare context. We identified individual, organizational and system characteristics, which are common to the 3 institutions/regions studied and constitute barriers for implementing the guideline to clinical practice. It is recommended that the 2008-Mexican-CPG-OA be thoroughly revised and restructured to improve the clarity of the actions implied by each recommendation. We propose some strategies to accomplish this and to overcome some of the identified regional/institutional barriers. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

CONDITIONS THAT INCREASE DRUG MARKET INVOLVEMENT: THE INVITATIONAL EDGE AND THE CASE OF MEXICANS IN SOUTH TEXAS

2010-01-01

Research on drug trafficking has not been able to discern the exact nature of illegal drug markets and the relationship between their individual and group participants. This article delineates the role of Mexican immigrants and Mexican-American participants involved in the stratified drug market of South Texas. This article synthesizes ethnographic materials drawn from two previous National Institute on Drug Abuse (NIDA) studies in order identify the different types of drug distribution behaviors that occur within the groups, the differentiated roles of individuals, the organizational framework, and most significantly, the processes that link market participants to others outside of the drug market. This illegal behavior can be interpreted as an adaptive mechanism that is a direct response to the marginal economic status imposed by macro socio-economical background factors. As well, we conclude that the specific foreground factors of the opportunities offered by the context, culture, and proximity of the U.S./Mexico border and invitational edges explain this behavior. There are both parallels and particular differences between the South Texas case and the structuring and functioning of informal legal and illegal markets that are characteristic of other economically disadvantaged communities.

Psychometric tests of Expectations of Filial Piety Scale in a Mexican-American population.

2007-08-01

This paper reports the development of the Expectations of Filial Piety Scale for use with Mexican-American parents regarding expectations they have of their adult children for care and support. Earlier work by the authors demonstrated that filial piety is a cross-cultural construct that can be used with Hispanic/Latino populations. More refined development of the construct required testing with more homogeneous subsets (i.e. Mexican-Americans) within the broad designation of Hispanic/Latino adults. Non-experimental methodological design for field testing of the instrument's psychometric properties. A convenient sample of 80 Mexican-American adults in California and Texas completed a brief biographical survey and field tested the Expectations of Filial Piety Scale. Common factor analysis with orthogonal rotation was used to extract three factors, which accounted for 58% of the variance in scale scores. These factors included: I: respect for parents (24.05%); II: honouring parents (12.5%); and III: family unity (16.56%). Overall scale reliability was 0.87 with individual factor reliability coefficients ranging from 0.74 to 0.87 and test-retest correlation was 0.73. The results show that the Expectations of Filial Piety Scale is an internally consistent and reliable tool for use in studies of the Mexican-American population. Mexican elders historically underuse formal services; a large portion of this population will most likely depend on support from their family members when they reach advanced ages. There is a lack of culturally sensitive instruments to measure family values in caring for older adults in Mexican-Americans. This scale can enable case workers and nurses in long-term care settings to assess the elder's expectations for family support accurately and compare these expectations with available family support, children's intentions to care for a dependent parent or other family member and the need for supplemental care in Mexican-American families.

Lemley, Megan; Spies, Lori A

2015-04-01

To describe selected common health beliefs and practices among Mexican American immigrants with type II diabetes. Selected clinical trials, qualitative studies, and systematic reviews. The Hispanic folk illness belief susto refers to an episode of severe fright, and Mexican American immigrants hold varying views on its relation to diabetes. Culturally and in the research, susto has also been linked with depression. Sabila (aloe vera) and nopal (prickly pear cactus) are herbal remedies that have had widespread, longstanding use in Mexican culture and while this is not the gold standard of research, it does provide ample evidence and a strong cultural belief that these therapies work. There is some evidence in the literature to support their efficacy as glucose-lowering agents, but lack of Food and Drug Administration (FDA) regulation, potential side effects, and a dearth of rigorous clinical trials preclude aloe vera and nopal from being recommended therapy. Awareness about susto beliefs, commonly used herbal remedies, and development of culturally sensitive communication skills are essential for nurse practitioners to effectively assist patients in this population achieve their glycemic goals. Research on the effects of nopal and aloe vera on diabetes is needed to guide clinical decisions. ©2014 American Association of Nurse Practitioners.

Genotoxic Evaluation of Mexican Welders Occupationally Exposed to Welding-Fumes Using the Micronucleus Test on Exfoliated Oral Mucosa Cells: A Cross-Sectional, Case-Control Study

2015-01-01

Background An estimated 800,000 people worldwide are occupationally exposed to welding-fumes. Previous studies show that the exposure to such fumes is associated with damage to genetic material and increased cancer risk. In this study, we evaluate the genotoxic effect of welding-fumes using the Micronucleus Test on oral mucosa cells of Mexican welders. Material and Methods We conducted a cross-sectional, matched case-control study of n = 66 (33 exposed welders, and 33 healthy controls). Buccal mucosa smears were collected and stained with acridine orange, observed under 100x optical amplification with a fluorescence lamp, and a single-blinded observer counted the number of micronuclei and other nuclear abnormalities per 2,000 observed cells. We compared the frequencies of micronuclei and other nuclear abnormalities, and fitted generalised linear models to investigate the interactions between nuclear abnormalities and the exposure to welding-fumes, while controlling for smoking and age. Results Binucleated cells and condensed-chromatin cells showed statistically significant differences between cases and controls. The frequency of micronuclei and the rest of nuclear abnormalities (lobed-nuclei, pyknosis, karyolysis, and karyorrhexis) did not differ significantly between the groups. After adjusting for smoking, the regression results showed that the occurrence of binucleated cells could be predicted by the exposure to welding-fumes plus the presence of tobacco consumption; for the condensed-chromatin cells, our model showed that the exposure to welding-fumes is the only reliable predictor. Conclusions Our findings suggest that Mexican welders who are occupationally exposed to welding-fumes have increased counts of binucleated and condensed-chromatin cells. Nevertheless, the frequencies of micronuclei and the rest of nuclear abnormalities did not differ between cases and controls. Further studies should shed more light on this subject. PMID:26244938

Occupational lifting tasks as a risk factor in low back pain: a case-control study in a Mexican population.

Prado-Leon, Lilia R; Celis, Alfredo; Avila-Chaurand, Rosalio

2005-01-01

The objective of this study was to quantify and assess whether lifting tasks in the workplace are a risk factor in lumbar spondyloarthrosis etiology. A case-control study was performed with 231 workers, 18-55 years old, insured by the Mexican Social Security Institute (IMSS, according to its designation in Spanish). A multivariate analysis using conditional logistical regression showed that lifting tasks, combined with driving tasks, are associated with this illness (OR = 7.3; 95% CI 1.7-31.4). The daily frequency of lifting as it interacts with work as a driver resulted in a greater risk (OR = 10.4; 95% CI 2.0-52.5). The load weight, daily task-hours and cumulative time showed a dose-response relationship. The attributable risk for lifting tasks was 0.83, suggesting that 83% of lumbar spondyloarthrosis development could be prevented if risk factors were eliminated by ergonomic redesign of the task.

To estimate the incidence of type 2 diabetes (T2D) in Mexican population. Population based prospective study. At baseline (1990), the population at risk (1939 non-diabetic adults 35-64 years) was evaluated with oral glucose tolerance test. Subsequent similar evaluations were done (1994, 1998, 2008). American Diabetes Association diagnostic criteria were applied. The period of observation was 27842 person-years, the cumulative incidence of T2D was 14.4 and 13.7 per 1000 person-years for men and women, respectively. Incidence was 15.8, 15.7 and 12.7 per 1 000 person-years for the second (1994), third (1998) and fourth (2008) follow-up phases, respectively. The mean age at diagnosis was 44 years for prevalent cases and 56 years for incident cases. This is the first estimate of long-term incidence of T2D in Mexican population. The incidence is among the highest reported worldwide. It remained with few changes throughout the study period.

Genetic and environmental determinants of the susceptibility of Amerindian derived populations for having hypertriglyceridemia

PubMed Central

Aguilar-Salinas, Carlos A.; Tusie-Luna, Teresa; Pajukanta, Päivi

2014-01-01

Here, we discuss potential explanations for the higher prevalence of hypertriglyceridemia in populations with an Amerindian background. Although environmental factors are the triggers, the search for the ethnic related factors that explains the increased susceptibility of the Amerindians is a promising area for research. The study of the genetics of hypertriglyceridemia in Hispanic populations faces several challenges. Ethnicity could be a major confounding variable to prove genetic associations. Despite that, the study of hypertriglyceridemia in Hispanics has resulted in significant contributions. Two GWAS reports have exclusively included Mexican mestizos. Fifty percent of the associations reported in Caucasians could be generalized to the Mexicans, but in many cases the Mexican lead SNP was different than that reported in Europeans. Both reports included new associations with apo B or triglycerides concentrations. The frequency of susceptibility alleles in Mexicans is higher than that found in Europeans for several of the genes with the greatest effect on triglycerides levels. An example is the SNP rs964184 in APOA5. The same trend was observed for ANGPTL3 and TIMD4 variants. In summary, we postulate that the study of the genetic determinants of hypertriglyceridemia in Amerindian populations which have major changes in their lifestyle, may prove to be a great resource to identify new genes and pathways associated with hypertriglyceridemia.

Mechanisms of social stratification require the categorical definition of an out-group to that can be excluded and exploited. Historically, in the United States, African Americans have been the subject of a systematic process of racial formation to define socially in this fashion. Beginning in the 1970s, however, and accelerating in the 1980s and 1990s, Mexicans were increasingly subject to processes of racialization that have rendered them more exploitable and excludable than ever before. Over the past decade, Mexican Americans moved steadily away from their middle position in the socioeconomic hierarchy and gravitated toward the bottom. This paper describes the basic mechanisms of stratification in the United States and how Mexicans have steadily been racialized to label them socially as a dehumanized and vulnerable out-group.

Tuberculosis (TB) is a leading public health problem and a recognized priority for the federal Governments of both Mexico and the United States of America. The objectives of this research, primarily for the four states in the United States that are along the border with Mexico, were to: (1) describe the epidemiological situation of TB, (2) identify TB risk factors, and (3) discuss tuberculosis program strategies. We analyzed tuberculosis case reports collected from 1993 through 2001 by the tuberculosis surveillance system of the United States. We used those data to compare TB cases mainly among three groups: (1) Mexican-born persons in the four United States border states (Arizona, California, New Mexico, and Texas), (2) persons in those four border states who had been born in the United States, and (3) Mexican-born persons in the 46 other states of the United States, which do not border Mexico. For the period from 1993 through 2001, of the 16 223 TB cases reported for Mexican-born persons in the United States, 12 450 of them (76.7%) were reported by Arizona, California, New Mexico, and Texas. In those four border states overall in 2001, tuberculosis case rates for Mexican-born persons were 5.0 times as high as the rates for persons born in the United States; those four states have 23 counties that directly border on Mexico, and the ratio in those counties was 5.8. HIV seropositivity, drug and alcohol use, unemployment, and incarceration were significantly less likely to be reported in Mexican-born TB patients from the four border states and the nonborder states than in patients born in the United States from the four border states (P < 0.001). Multivariate analysis revealed that among pulmonary tuberculosis patients who were 18-64 years of age and residing in the four border states, the Mexican-born patients were 3.6 times as likely as the United States-born patients were to have resistance to at least isoniazid and rifampin (i. e., to have multidrug-resistant TB) and twice as likely to have isoniazid resistance. Mexican-born TB patients from the four border states and the nonborder states were significantly more likely to have moved or to be lost to follow-up than were the TB patients born in the United States from the four border states (P < 0.001). Increased collaborative tuberculosis control efforts by the federal Governments of both Mexico and the United States along the border that they share are needed if tuberculosis is to be eliminated in the United States.

Several factors contribute to the increase in breast cancer (BC) incidence, such as lifetime exposure to estrogen, early menarche and older ages at first birth, menopause, and the increased prevalence of postmenopausal obesity. In fact, there is an association between an increased BC risk and elevated estrogen levels, which may be involved in carcinogenesis via the estrogen receptor alpha (ERα) encoded by the ESR1 gene. Interestingly, there is an antagonistic relationship between ERα and the aryl hydrocarbon receptor (AhR) in BC cells. Herein, we explore the combined effects of the ESR1 (XbaI, PvuII) and AhR polymorphisms on BC development in Mexican women according to their menopausal status. Investigation was performed using a cases and controls design. In a group of 96 cases diagnosed with BC and 111 healthy women, the single-nucleotide polymorphisms ESR1 (XbaI, PvuII) and AhR gene were identified by qPCR. Chi-square test or Fisher's exact test were used. Statistical analyses were conducted using the STATA statistical package (Version 10.1, STATA Corp., College Station, TX, USA). The G/G XbaI genotype was more prevalent in the cases than in the controls (P = 0.008). Moreover, Mexican women carrying the XbaI (wild type [WT]/G or G/G) ESR1 genotype have higher risk (12.26-fold) for developing postmenopausal BC than individuals carrying the WT/WT genotype. The presence of the G/G genotype of XbaI may be considered a susceptibility allele in Mexican women. Due to increased postmenopausal BC risk, the XbaI (WT/G or G/G) alleles may be used as a postmenopausal predictive factor for BC in Mexican women.

Subnormal visual acuity (SVAS) and albinism in Mexican 12-13-year-old children.

In a previous study the vision of 1046 12-13-year-olds in Sweden was examined. Of those 67 had some kind of visual disturbances and in 20 no obvious cause was found. In this group, defined as children with subnormal visual acuity syndromes (SVAS), albinism was shown to be a major cause to the visual dysfunction giving a prevalence of about 1%. This is about 100 times higher than previous figures. Albinism can therefore be the cause in many cases of unexplained low visual acuity, at least in Sweden. Subnormal visual acuity is usually found in 2-4% in a pediatric population and is often called 'amblyopia'. The Swedish study showed that in many cases 'amblyopia' should be replaced by 'SVAS' and further investigation. The present Mexican study was designed identically to the Swedish study. The objective was to describe the distribution of visual acuity and the prevalence of ocular disorders, including incidence of subnormal visual acuity (SVAS) and the occurrence of albinism in a Mexican population of 12-13-year-olds. Altogether 1035 children, 12-13 years of age, were examined. A total number of 344 children were referred to the university pediatric eye clinic for further examination. 272 of these had simple refractive errors, 59 were diagnosed with an ophthalmological disorder and 13 children could not be pathologically classified. These were referred to a second ophthalmological examination, including VEP (Visual Evoked Potential) recordings. VEP reveals an asymmetric (right vs. left) cortical response after monocular stimulation in albinism. No child showed iris translucency or any other typical albinoic sign. VEP was recorded from 11 children. Three children showed an asymmetric VEP and were classified as albinos. The VEP response was normal in 8 of the children. The results indicate that albinism is common in Mexico, although not as common as in a similar Swedish population. A prevalence of albinism of approximately 0.3% was found in the Mexican population, compared to approximately 1% in the Swedish study group. The number of albinos was much higher in both study groups than to be expected from previous estimates. The difference between the Swedish and the Mexican figures may be explained by the general difference in pigmentation between Sweden and Mexico and thus probably by the subsequent lower number of commonly occurring albino foci in the Mexican heritage. It is emphasised that in investigations of children with SVAS, also in countries with a generally high pigmentation level, electro-physiological examinations are important, to be able to reveal albinism, but also to exclude or verify other conditions in the SVAS group, for example neurometabolic conditions.

In the United States, the prevalence of childhood overweight and obesity has reached epidemic levels, with U.S. Hispanic children, a sub-group mainly composed of children of Mexican decent, disproportionately affected. Prior research has suggested that Mexican parents may view overweight in early childhood as desirable; however, it is unclear if this is still the case. Therefore, this qualitative study explored the beliefs of 11 Mexican parents of preschoolers regarding weight and health. Following coding and clustering of themes from the transcribed audio-recorded meetings, six patterns were identified: (a) meanings and relationships about excess weight in childhood and child health, (b) causes of overweight and obesity, (c) uncertainty about knowing and not knowing, (d) from Mexico to America: enticements of a new land and time as a commodity, (e) the effects of society on personal and parental goals: the work of parenting in the United States, and (f) identified needs and action strategies. In summary, parents involved in this group discussion readily associated overweight/obesity with poor mental and physical health; however, they were uncertain how they would "know" if their children were overweight.

Among Mexican Americans the prevalence of gallbladder disease is markedly elevated. Previous data from both genetic admixture and family studies indicate that there is genetic component to the occurrence of gallbladder disease in Mexican Americans. However, prior to this study no formal genetic analysis of gallbladder disease had been carried out nor had any contributing gene been identified. The results of complex segregation analysis in a sample of 232 Mexican Americans with age- and gender-specific effects influencing the occurrence of gallbladder disease. The estimated frequency of the allele increasing susceptibility was 0.39. The lifetime probabilities that an individual will bemore » affected by gallbladder disease were 1.0, 0.54, and 0.00 for females of genotypes {open_quotes}AA{close_quotes}, {open_quotes}Aa{close_quotes}, and {open_quotes}aa{close_quotes}, respectively, and 0.68, 0.30, and 0.00 for males, respectively. Human cholesterol 7a-hydroxylase is the rate-limiting enzyme in bile acid synthesis. The results of an association study in both a random sample and a matched case/control sample showed that there is a significant association between cholesterol 7a-hydroxylase gene variation and the occurrence of gallbladder disease in Mexican Americans males but not in females. For loci in the 5{prime}-end of the cholesterol 7a-hydroxylase gene, the frequency of the susceptibility alleles was twice as high in gallbladder disease patients compared to controls. The results of a linkage analysis provide evidence that the cholesterol 7a-hydroxylase gene and the inferred gallbladder disease gene are genetically linked.« less

Background Frequent recurrent BRCA1 and BRCA2 gene (BRCA) mutations among Hispanics, including a large rearrangement Mexican founder mutation (BRCA1 ex9-12del), suggest that an ancestry-informed BRCA-testing strategy could reduce disparities and promote cancer prevention by enabling economical screening for hereditary breast and ovarian cancer in Mexico. Methods In a multistage approach, 188 cancer cases unselected for family cancer history (92 ovarian cancer and 96 breast cancer) were screened for BRCA mutations using a Hispanic mutation panel (HISPANEL®) of 115 recurrent mutations in a multiplex assay (114 on a mass spectroscopy platform, and a PCR assay for the BRCA1 ex9-12del mutation), followed by sequencing of all BRCA exons and adjacent intronic regions, and BRCA1 multiplex ligation-dependent probe amplification assay (MLPA) for HISPANEL negative cases. BRCA mutation prevalence was calculated and correlated with histology and tumor receptor status, and HISPANEL sensitivity was estimated. Results BRCA mutations were detected in 28% (26/92) of ovarian cancer cases and 15% (14/96) of breast cancer cases overall and 27% (9/33) of triple negative breast cancer. Most breast cancer cases were diagnosed with locally advanced disease. The Mexican founder mutation (BRCA1 ex9-12del) accounted for 35% of the BRCA-associated ovarian cancer cases and 29% of the BRCA-associated breast cancer cases. At 2% of the sequencing and MLPA cost, the HISPANEL detected 68% of all BRCA mutations. Conclusion In this study, we found a remarkably high prevalence of BRCA mutations among ovarian and breast cases not selected for family history, and BRCA1 ex9-12del explained one third of the total. The remarkable frequency of BRCA1 ex9-12del in Mexico City supports a nearby origin of this Mexican founder mutation and may constitute a regional public health problem. The HISPANEL presents a translational opportunity for cost-effective genetic testing to enable breast and ovarian cancer prevention. PMID:25236687

To evaluate the criterion validity and diagnostic utility of the SCOFF, a brief eating disorder (ED) screening instrument, in a Mexican sample. The study was conducted in two phases in 2012. Phase I involved the administration of self-report measures [the SCOFF and the Eating Disorder Inventory-2, (EDI-2)] to 1057 students aged 17-56 years (M age = 21.0, SD = 3.4; 67 % female) from three colleges at the Universidad Autónoma de San Luis Potosí, Mexico. In Phase II, a random subsample of these students (n = 104) participated in the eating disorder examination, a structured interview that yields ED diagnoses. Analyses were conducted to evaluate the SCOFF's criterion validity by examining (a) correlations between scores on the SCOFF and the EDI-2 and (b) the SCOFF's ability to differentiate diagnosed ED cases and non-cases. EDI-2 subscales showed high correlations with the SCOFF scores proving initial evidence of criterion validity. A score of two points on the SCOFF optimized the sensitivity (78 %) and specificity (84 %). With this cutoff, the SCOFF correctly classified over half the cases (PPV = 58 %) and screened out the majority of non-cases (NPV = 93 %) providing further evidence of criterion validity. Analyses were repeated separately for men and women, yielding gender-specific information on the SCOFF's performance. Taken as a whole, results indicated that the SCOFF can be a useful tool for identifying Mexican university students who are at risk of eating disorders.

Towards an Informed Mexican and Mexican-American Citizenry: Bridging the Gap to Increase Human Capacity and Information Dissemination

The research translation and community outreach goal of The University of Arizona's (UA) Superfund Basic Research Program and U.S.-Mexico Binational Center for Environmental Sciences and Toxicology is to increase human capacity and information dissemination to diverse stakeholders, including federal, state, and local government agencies as well as northern Mexican and border community stakeholders. Due to Arizona's demographic characteristics and the UA's proximity to the U.S. - Mexico border, activities target primarily Mexican and Mexican-American populations. With this in mind, a model has been established that pulls from human capital, community-based participatory research and public participation theories. The theories applied to our target population have resulted in the creation of a successful model that is used in both research translation and community outreach work. The model contains four components: community needs (participation), science translation (information), engagement (outreach), and training (education). Examples of how this model operates for various stakeholders involved in environmental science and health issues will be discussed. A case in point of how this model has been applied effectively is the partnership with promotoras (community health advocates) to do environmental science and health trainings to increase the knowledge base of specific populations disproportionately exposed to contaminants of concern. Additional case studies and methodologies used to develop innovative communicative tools (that takes into consideration cultural idiosyncrasies) for stakeholders at all levels in Arizona, the border, and Mexico will be highlighted, such as: 1) information sheets regarding local environmental issues for communities neighboring contaminated sites, 2) SciTransfer Bulletins targeting professional level stakeholders such as Project Managers, Community Involvement Coordinators and the general public, 3) coordinating technical and scientific workshops in the U.S and Mexico and 4) participating in local community events. Lessons learned and knowledge gained in the past three years will also be presented.

Phylogeny and Evolutionary Patterns in the Dwarf Crayfish Subfamily (Decapoda: Cambarellinae)

2012-01-01

The Dwarf crayfish or Cambarellinae, is a morphologically singular subfamily of decapod crustaceans that contains only one genus, Cambarellus. Its intriguing distribution, along the river basins of the Gulf Coast of United States (Gulf Group) and into Central México (Mexican Group), has until now lacked of satisfactory explanation. This study provides a comprehensive sampling of most of the extant species of Cambarellus and sheds light on its evolutionary history, systematics and biogeography. We tested the impact of Gulf Group versus Mexican Group geography on rates of cladogenesis using a maximum likelihood framework, testing different models of birth/extinction of lineages. We propose a comprehensive phylogenetic hypothesis for the subfamily based on mitochondrial and nuclear loci (3,833 bp) using Bayesian and Maximum Likelihood methods. The phylogenetic structure found two phylogenetic groups associated to the two main geographic components (Gulf Group and Mexican Group) and is partially consistent with the historical structure of river basins. The previous hypothesis, which divided the genus into three subgenera based on genitalia morphology was only partially supported (P = 0.047), resulting in a paraphyletic subgenus Pandicambarus. We found at least two cases in which phylogenetic structure failed to recover monophyly of recognized species while detecting several cases of cryptic diversity, corresponding to lineages not assigned to any described species. Cladogenetic patterns in the entire subfamily are better explained by an allopatric model of speciation. Diversification analyses showed similar cladogenesis patterns between both groups and did not significantly differ from the constant rate models. While cladogenesis in the Gulf Group is coincident in time with changes in the sea levels, in the Mexican Group, cladogenesis is congruent with the formation of the Trans-Mexican Volcanic Belt. Our results show how similar allopatric divergence in freshwater organisms can be promoted through diverse vicariant factors. PMID:23155379

Current metastatic colorectal cancer (mCRC) therapy uses monoclonal antibodies against the epidermal growth factor receptor. This treatment is only useful in the absence of K-RAS gene mutations; therefore the study of such mutations is part of a personalized treatment. The aim of this work is to determine the frequency and type of the most common K-RAS mutations in Mexican patients with metastatic disease by nucleotide sequencing. We studied 888 patients with mCRC from different regions of Mexico. The presence of mutations in exon 2, codons 12 and 13, of the K-RAS gene was determined by nucleotide sequencing. Patients exhibited K-RAS gene mutations in 35% (310/888) of cases. Mutation frequency of codons 12 and 13 was 71% (221/310) and 29% (89/310), respectively. The most common mutation (45.7%) in codon 12 was c.35G>A (p.G12D), whereas the one in codon 13 was c.38G>A (p.G13D) (78.7%). Given the frequency of K-RAS mutations in Mexicans, making a genetic study before deciding to treat mCRC patients with monoclonal antibodies is indispensable.

2000-01-01

Pesticides having a high adverse effect on the health and environment of inhabitants of the Mexican Republic were studied to establish the main parameters to bear in mind for their use and application. The investigation showed that Mexico is the agricultural zone with the highest health damage to its population from pesticides. The valid regulation norms for the use and application of these agrochemicals were analyzed. Case histories recorded by the public health sector in Mexico were reviewed. In this way, a strong relation was found between the health problems and the pesticides applied. Finally, the study concludes that the various Mexican States appear as a risk zone because of contamination by pesticides that are permitted by the regulation norms and by others whose use is prohibited in other countries and in Mexico. This situation causes a serious effect on the health deterioration of people who are exposed to these agro-chemicals and, in some cases, leads to death.

Mexican farmworker women's perspectives on drinking in a migrant community.

Alcohol use in farmworker communities has not been investigated to any extent. The literature on alcohol consumption and farmworkers is virtually nonexistent. This case study provides information on drinking patterns and problems in a Mexican farmworker community in Northern California. The focus is on Mexican farmworker women's perspectives on drinking in a specific social context: A migrant farmworker housing center. Male responses are provided as a basis for comparison and contrast. The study examines issues related to driving under the influence, public versus private space, and the centrality of considerations regarding children/youth in setting acceptable parameters for drinking. Data collection consisted of observations and 29 interviews of men (13) and women (16) farmworkers over a 6-month period in 1991. We found that most of the women in the camp abstain from drinking. They define male drinking as a problem when 1) youth are allowed and encouraged to drink, 2) an increase of individuals driving under the influence in the housing center becomes evident, and 3) when drinkers serve as poor role models for youth.

Metabolic syndrome is the main health problem in Mexico. Its two principal complications (ischemic cardiopathy and type-2 diabetes) are the two main causes of death in Mexico since 2000. To describe the prevalence of the metabolic syndrome in adults from 20 to 40 years old in a Mexican rural community (Senegal de Palomas, San Juan del Río, Querétaro) using the National Cholesterol Education Program (NCEP III) definition. A descriptive study with a random sample was carried out. We present a univariate analysis with a 95% confidence interval. 73 cases were studied. The prevalence of the metabolic syndrome was 45.2% slightly higher in men (48.4%) than in women (42.8%). The prevalence of hypertension was 27.3%. The prevalence of obesity was 26.1% using the definition of the WHO and this prevalence rises up to 49.4% using the definition of the Mexican Official Norm. 90.5% of women and 93.5% of men had low HDLc. The prevalence of metabolic syndrome in adults from 20 to 40 years old in this Mexican rural community is much higher than the national mean for the same age cohort. The results show the necessity to increase the research of our rural communities in order to identify the possible causes to this problem and to create therapeutic programs for patients with metabolic syndrome.

We analyzed commonly reported European and Asian obesity-related gene variants in a Mexican-Mestizo population through each single nucleotide polymorphism (SNP) and a genetic risk score (GRS) based on 23 selected SNPs. Study subjects were physically active Mexican-Mestizo adults (n  =  608) with body mass index (BMI) values from 18 to 55 kg/m 2 . For each SNP and for the GRS, logistic models were performed to test for simple SNP associations with BMI, fat mass percentage (FMP), waist circumference (WC), and the interaction with VO 2max and muscular endurance (ME). To further understand the SNP or GRS*physical fitness components, generalized linear models were performed. Obesity risk was significantly associated to 6 SNPs (ADRB2 rs1042713, APOB rs512535, PPARA rs1800206, TNFA rs361525, TRHR rs7832552 and rs16892496) after adjustment by gender, age, ancestry, VO 2max , and ME. ME attenuated the influence of APOB rs512535 and TNFA rs361525 on obesity risk in FMP. WC was significantly associated to GRS. Both ME and VO 2max attenuated GRS effect on WC. We report associations for 6 out of 23 SNPs and for the GRS, which confer obesity risk, a novel finding for Mexican-Mestizo physically active population. Also, the importance of including physical fitness components variables in obesity genetic risk studies is highlighted, with special regard to intervention purposes. © 2017 John Wiley & Sons Ltd/University College London.

Considering that the Mexican mestizo population seems to be the result of a genetic admixture, we proposed that further research is needed to evaluate the role of ethnicity in conjunction with health-related factors to better understand ethnic differences in bone mineral density (BMD). The aim of this study was to analyze several risk factors related to the development of osteoporosis in postmenopausal Mexican mestizo women. We included 567 postmenopausal Mexican mestizo women. A structured questionnaire for risk factors was applied and BMD was measured in total hip and lumbar spine by dual-energy x-ray absorptiometry. Nonconditional logistic regression was used to estimate crude and adjusted odds ratio. Using World Health Organization criteria, 28.7% of postmenopausal women had osteoporosis, 46.4% had osteopenia, and 24.9% had normal BMD. Each clinical risk factor had a different significance for osteopenia/osteoporosis; however, duration of total breast-feeding, body mass index, and number of years since menopause remained significantly associated with osteopenia/osteoporosis after bone density was added to the nonconditional model. Interestingly, extended periods of accumulated breast-feeding for 24 and 36 months were, in both cases, significantly associated with osteopenia/osteoporosis. Our results confirm the importance of considering the duration of breast-feeding as an important risk factor for osteopenia/osteoporosis. In addition, we find that body mass index is positively associated with BMD. Because of the heterogeneity of the Mexican mestizo population, the risk factor for osteoporosis may not be the same in different ethnic groups.

As part of a 5-year community-based intervention in Salinas, California, the Steps to a Healthier Salinas team developed a taqueria intervention addressing obesity and diabetes among Mexican Americans. The authors present: (a) a comparison of service/entrée options for Salinas taquerias (n = 35) and fast-food restaurants ( n = 38) at baseline, (b) a case study of one taqueria, (c) a description of a healthy nutrition tool kit tailored to taquerias, and (d) an evaluation of the intervention at Year 3. It was found that traditional Mexican American-style menu offerings at taquerias tended to be healthier than American-style fast-food restaurant offerings. In addition, the initial response to the intervention has shown positive changes, which include the taqueria owners promoting available healthy menu items and modifying other menu offerings to reduce fats and increase fruit and vegetable availability. This, in turn, has led to a transition of the owners' perceptions of themselves as gatekeepers for a healthy community.

2008-01-01

Purpose Paired box gene 6 (PAX6) heterozygous mutations are well known to cause congenital non-syndromic aniridia. These mutations produce primarily protein truncations and have been identified in approximately 40%–80% of all aniridia cases worldwide. In Mexico, there is only one previous report describing three intragenic deletions in five cases. In this study, we further analyze PAX6 variants in a group of Mexican aniridia patients and describe associated ocular findings. Methods We evaluated 30 nonrelated probands from two referral hospitals. Mutations were detected by single-strand conformation polymorphism (SSCP) and direct sequencing, and novel missense mutations and intronic changes were analyzed by in silico analysis. One intronic variation (IVS2+9G>A), which in silico analysis suggested had no pathological effects, was searched in 103 unaffected controls. Results Almost all cases exhibited phenotypes that were at the severe end of the aniridia spectrum with associated ocular alterations such as nystagmus, macular hypoplasia, and congenital cataracts. The mutation detection rate was 30%. Eight different mutations were identified: four (c.184_188dupGAGAC, c.361T>C, c.879dupC, and c.277G>A) were novel, and four (c.969C>T, IVS6+1G>C, c.853delC, and IVS7–2A>G) have been previously reported. The substitution at position 969 was observed in two patients. None of the intragenic deletions previously reported in Mexican patients were found. Most of the mutations detected predict either truncation of the PAX6 protein or conservative amino acid changes in the paired domain. We also detected two intronic non-pathogenic variations, IVS9–12C>T and IVS2+9G>A, that had been previously reported. Because the latter variation was considered potentially pathogenic, it was analyzed in 103 healthy Mexican newborns where we found an allelic frequency of 0.1116 for the A allele. Conclusions This study adds four novel mutations to the worldwide PAX6 mutational spectrum, and reaffirms the finding that c.969C>T is one of the three more frequent causal mutations in aniridia cases. It also provides evidence that IVS2+9G>A is an intronic change without pathogenic effect. PMID:18776953

The relationship between Mexican American cultural values and resilience among Mexican American college students: a mixed methods study.

Morgan Consoli, Melissa L; Llamas, Jasmin D

2013-10-01

The current study investigated the role of cultural values in the resilience of Mexican American college students. Utilizing mixed methodology, 124 self-identified Mexican American college students were asked to complete an online survey, including a demographic questionnaire, the Resilience Scale, Mexican American Cultural Values Scale, and 2 open-ended questions concerning overcoming adversity and cultural values. As hypothesized, Mexican American traditional cultural values (Familismo, Respeto, Religiosidad, and Traditional Gender Roles) predicted resilience, with Familismo accounting for the majority of the variance. Consensual qualitative research (Hill, Thompson, & Nutt Williams, 1997) was used to identify emergent domains and themes within the open-ended question responses. Traditional Mexican American Value themes included Familismo, Ethnic Identity, Religiosidad, Perseverance, and Respeto. Results highlight the important role that certain Mexican American cultural values play in providing strength for overcoming adversities.

Unpacking acculturation: cultural orientations and educational attainment among Mexican-origin youth.

2012-07-01

Given educational risks facing Mexican-origin children of immigrant parents, it is important to understand how aspects of the acculturation process influence Mexican-origin youth's educational success. Drawing from selective assimilation theory, this study examined how cultural orientations across myriad facets of acculturation were associated with the educational attainment of second-generation Mexican immigrant youth. The sample included 755 Mexican-origin youth (50% female) in the "Children of Immigrants Longitudinal Study." Results from structural equation models indicated that youth reporting greater facility in the English language and a stronger value on familism attained higher levels of education in young adulthood than did other youth. Parents' U.S. social ties and youth's value on early paid work were associated with less educational attainment. Innovative findings from this study indicate the importance of considering both Mexican and American cultural orientations across myriad facets of acculturation for understanding second-generation immigrant Mexican youth's educational attainment.

Primary osteoarthritis (OA) is a complex entity in which several loci related to different molecular pathways or classes of molecules are associated with its development as demonstrated through genetic association studies. Genes involved in bone formation and mineralization, such as osteopontin (OPN) and Matrix Gla protein (MGP), could also be related with OA. The aim of this study was to evaluate the association between the genetic variants of OPN and MGP with primary knee osteoarthritis in a Mexican population. A case-control study was conducted in 296 patients with primary knee osteoarthritis and in 354 control subjects. Study groups were assessed radiologically. The rs11730582 of OPN and rs1800802, rs1800801, and rs4236 of MGP were determined by TaqMan allele discrimination assays. The haplotypes of the polymorphisms of MGP were constructed. The association was tested through univariate and multivariate non-conditional logistic regression analyses. The polymorphisms of MGP complied with Hardy-Weinberg (HW) equilibrium. The polymorphisms of OPN and MGP were not significantly associated with primary knee osteoarthritis in the codominant, dominant, and recessive models (p > 0.05). Our study suggests that there are no associations between OPN and MGP polymorphisms with primary knee osteoarthritis in Mexican population.

Culturally tailored diabetes self-management education (DSME) improves glycemic control and other health outcomes in Mexican Americans but sociocultural barriers to health improvements remain. This study explored the feasibility of adding a nurse case manager (NCM) to DSME to foster DSME attendance and increase utilization of other available health care services. The setting was a rural community on the Texas-Mexico border in one of the poorest counties in the United States. Using a repeated measures pretest, post-test control group design, we enrolled 165 Mexican American adults into: 1) an experimental group that received a DSME intervention plus access to a NCM; or 2) a control group that received DSME only. Both experimental and control groups received the DSME intervention, reported positive changes in diet and physical activity, and showed improved clinical outcomes; there were no significant group differences. A statistically significant reduction in body mass index was seen in women compared to men, regardless of group or number of NCM contacts. For individuals having the most NCM contacts, DSME attendance rates were greater. Participants expressed acceptance of the NCM; they preferred face-to-face contact rather than by telephone. Our previously tested, culturally tailored DSME continues to be an effective strategy for improving glycemic control in Mexican Americans. This feasibility study provided partial support for the NCM model for underserved border communities, but additional research is needed on resource utilization and the nature of NCM contacts.

Fleuriet, K Jill; Sunil, T S

2014-05-01

The purpose of this study was to determine differences in subjective social status, perceived social stress, depressive symptoms, and pregnancy-related anxiety between pregnant Mexican American and Mexican immigrant women. Three hundred pregnant Mexican immigrant and Mexican American women in South Texas were surveyed for pregnancy-related anxiety, perceived social stress, depressive symptoms, and subjective social status. Pregnant Mexican immigrant women had higher levels of pregnancy-related anxiety and lower levels of depression and perceived social stress than pregnant Mexican American women. Change in these variables among Mexican immigrant women was relatively linear as time of residence in the United States increased. Mexican immigrant and Mexican American women had significantly different correlations between subjective social status, self-esteem and perceived social stress. Results indicate that subjective social status is an important psychosocial variable among pregnant Hispanic women. Results contribute to ongoing efforts to provide culturally responsive prenatal psychosocial support services.

2012-08-01

We conducted a cross-sectional study among 1,717 children and adolescents of Mexican origin ages 5-19 years living in Mexico and Texas to explore the influence of country of birth and country of longest residence on their overweight and obesity status. Descriptive statistics were used to compare demographic and anthropometric characteristics of participants born and raised in Mexico (Mexicans), born in Mexico and raised in the United States (Mexican immigrants), and born and raised in the United States (Mexican-Americans). Univariate and multivariate nominal logistic regression was used to determine the demographic predictors of obesity adjusted by country of birth, country of residence, age, and gender. Almost half (48.8%) of the Mexican-Americans and 43.2% of the Mexican immigrants had body mass index at the 85th percentile or above, compared to only 29.3% of the Mexicans (P < .001). Thus, Mexican-Americans and Mexican immigrants were more likely to be obese than their Mexican peers [Mexican-Americans: odds ratio (OR) = 2.5 (95% confidence interval [CI] 1.8-3.4); Mexican immigrants: OR = 2.2 (95% CI 1.6-3.0)]. In addition, males were more likely than females to be obese [OR = 1.6 (95% CI 1.2-2.1)], and adolescents 15-19 years of age were less likely than their younger counterparts [OR = 0.5 (95% CI 0.4-0.7)] to be obese. The high prevalence of obesity among children of Mexican origin in the United States is of great concern and underscores the urgent need to develop and implement obesity preventive interventions targeting younger children of Mexican origin, especially newly arrived immigrant children. In addition, future obesity research should take into consideration the country of origin of the study population to develop more culturally specific obesity interventions.

Transnational science and collaborative networks. The case of Genetics and Radiobiology in Mexico, 1950-1970.

PubMed

Barahona, Ana

2015-01-01

The transnational approach of the science and technology studies (S&TS) abandons the nation as a unit of analysis in order to understand the development of science history. It also abandons Euro-US-centred narratives in order to explain the role of international collaborative networks and the circulation of knowledge, people, artefacts and scientific practices. It is precisely under this perspective that the development of genetics and radiobiology in Mexico shall be analyzed, together with the pioneering work of the Mexican physician-turned-geneticist Alfonso León de Garay who spent two years in the Galton Laboratory in London under the supervision of Lionel Penrose. Upon his return de Garay funded the Genetics and Radiobiology Program of the National Commission of Nuclear Energy based on local needs and the aim of working beyond geographical limitations to thus facilitate the circulation of knowledge, practices and people. The three main lines of research conducted in the years after its foundation that were in line with international projects while responding to the national context were, first, cytogenetic studies of certain abnormalities, and the cytogenetics and anthropological studies of the Olympic Games held in Mexico in 1968; second, the study of the effects of radiation on hereditary material; and third, the study of population genetics in Drosophila and in Mexican indigenous groups. The program played a key role in reshaping the scientific careers of Mexican geneticists, and in transferring locally sourced research into broader networks. This case shows the importance of international collaborative networks and circulation in the constitution of national scientific elites, and also shows the national and transnational concerns that shaped local practices.

Introduction Our aim was to compare the longitudinal lung function growth of Mexican children and adolescents with the collated spirometric reference proposed for international use and with that of Mexican-Americans from the National Health State Examination Survey III (NHANES) III study. Materials and Methods A cohort of Mexican children in third year of primary school was followed with spirometry twice a year through secondary school. Multilevel mixed-effects lineal models separated by gender were fit for the spirometric variables of 2,641 respiratory-healthy Mexican children expressed as Z-scores of tested reference equations. Impact of adjustment by sitting height on differences with Mexican-American children was observed in a subsample of 1,987 children. Results At same gender, age, and height, Mexican children had increasingly higher forced expiratory volume in 1 s (FEV1) and Forced vital capacity (FVC) than the children from the collated reference study (mean Z-score, 0.68 for FEV1 and 0.51 for FVC) and than Mexican-American children (Z-score, 0.23 for FEV1 and 0.21 for FVC) respectively. Differences with Mexican-Americans were not reduced by adjusting by sitting height. Conclusions For reasons that remain unclear, the gender-, age-, and height-adjusted lung function of children from Mexico City is higher than that reported by several international studies.

2017-01-01

There are currently about 415 million people with diabetes worldwide, a figure likely to increase to 642 million by 2040. In 2015, Mexico was the second Latin American country and sixth in the world in prevalence of this disorder with nearly 11.5 million of patients. Type 2 diabetes (T2D) is the main kind of diabetes and its etiology is complex with environmental and genetic factors involved. Indeed, polymorphisms in several genes have been associated with this disease worldwide. To estimate the genetic epidemiology of T2D in Mexican mestizos a systematic bibliographic search of published articles through PubMed, Scopus, Google Scholar, and Web of Science was conducted. Just case-control studies of candidate genes about T2D in Mexican mestizo inhabitants were included. Nineteen studies that met the inclusion criteria were found. In total, 68 polymorphisms of 41 genes were assessed; 26 of them were associated with T2D risk, which were located in ABCA1, ADRB3, CAPN10, CDC123/CAMK1D, CDKAL1, CDKN2A/2B, CRP, ELMO1, FTO, HHEX, IGF2BP2, IRS1, JAZF1, KCNQ1, LOC387761, LTA, NXPH1, SIRT1, SLC30A8, TCF7L2, and TNF-α genes. Overall, 21 of the 41 analyzed genes were associated with T2D in Mexican mestizos. Such a genetic heterogeneity compares with findings in other ethnic groups.

Several studies have identified nearly 40 different type 2 diabetes susceptibility loci, mainly in European populations, but few of them have been evaluated in the Mexican population. The aim of this study was to examine the extent to which 24 common genetic variants previously associated with type 2 diabetes are associated in Mexican Mestizos. Twenty-four single nucleotide polymorphisms (SNPs) in or near genes (KCNJ11, PPARG, TCF7L2, SLC30A8, HHEX, CDKN2A/2B, CDKAL1, IGF2BP2, ARHGEF11, JAZF1, CDC123/CAMK1D, FTO, TSPAN8/LGR5, KCNQ1, THADA, ADAMTS9, NOTCH2, NXPH1, RORA, UBQLNL, and RALGPS2) were genotyped in Mexican Mestizos. A case-control association study comprising 1,027 type 2 diabetic individuals and 990 control individuals was conducted. To account for population stratification, a panel of 104 ancestry-informative markers was analyzed. Association to type 2 diabetes was found for rs13266634 (SLC30A8), rs7923837 (HHEX), rs10811661 (CDKN2A/2B), rs4402960 (IGF2BP2), rs12779790 (CDC123/CAMK1D), and rs2237892 (KCNQ1). In addition, rs7754840 (CDKAL1) was associated in the nonobese type 2 diabetic subgroup, and for rs7903146 (TCF7L2), association was observed for early-onset type 2 diabetes. Lack of association for the rest of the variants may have resulted from insufficient power to detect smaller allele effects. PMID:22923468

RACE/ETHNICITY AND U.S. ADULT MORTALITY

Although there have been significant decreases in U.S. mortality rates, racial/ethnic disparities persist. The goals of this study are to: (1) elucidate a conceptual framework for the study of racial/ethnic differences in U.S. adult mortality, (2) estimate current racial/ethnic differences in adult mortality, (3) examine empirically the extent to which measures of socioeconomic status and other risk factors impact the mortality differences across groups, and (4) utilize findings to inform the policy community with regard to eliminating racial/ethnic disparities in mortality. Relative Black-White differences are modestly narrower when compared to a decade or so ago, but remain very wide. The majority of the Black-White adult mortality gap can be accounted for by measures of socioeconomic resources that reflect the historical and continuing significance of racial socioeconomic stratification. Further, when controlling for socioeconomic resources, MexicanAmericans and Mexican immigrants exhibit significantly lower mortality risk than non-Hispanic Whites. Without aggressive efforts to create equality in socioeconomic and social resources, Black-White disparities in mortality will remain wide, and mortality among the Mexican-origin population will remain higher than what would be the case if that population achieved socioeconomic equality with Whites.

Subjective Social Status, Mental and Psychosocial Health, and Birth Weight Differences in Mexican-American and Mexican Immigrant Women.

PubMed

Fleuriet, K Jill; Sunil, T S

2015-12-01

Recent Mexican immigrant women on average have an unexpectedly low incidence of low birth weight (LBW). Birth weights decline and LBW incidence increases in post-immigrant generations. This pilot project tested the hypothesis that subjective social status (SSS) of pregnant women predicts variation in birth weight between Mexican immigrant and Mexican-American women. 300 low-income pregnant Mexican immigrant and Mexican-American women in South Texas were surveyed for SSS, depression, pregnancy-related anxiety, perceived social stress and self-esteem and subsequent birth weight. No significant difference in SSS levels between pregnant Mexican immigrant and Mexican-American women were found. However, SSS better predicted variation in birth weight across both groups than mental and psychosocial health variables. Results suggest distinct relationships among SSS, mental and psychosocial health that could impact birth weight. They underscore the relevance of a multilevel, biopsychosocial analytical framework to studying LBW.

Verjovsky, Janet; Waldegg, Guillermina

2005-04-01

This article explores the beliefs and practices of a high school biology teacher through three interrelated theoretical frameworks: common knowledge, collaborative learning, and communities of practice. The data were obtained from an in-depth case study of Maria, a biology teacher from a Mexican public high school that was participating in a 4-year international science project using collaborative learning and information and communication technology. Her beliefs and practices were explored by means of questionnaires, semi-structured interviews, and nonparticipant observation of classes. Through the use of the three-component framework, the degrees of coherence between practice and beliefs that guide the teacher's daily behavior became apparent, as well as the difficulties of incorporating innovations due to institutional constraints.

Mexico has cultivated opium poppy since before the 1900's and has been an important transit route for South American cocaine for decades. However, only recently has drug use, particularly injection drug use, been documented as an important problem. Heroin is the most common drug used by Mexican injection drug users (IDUs). Increased cultivation of opium poppy in some Mexican states, lower prices for black tar heroin and increased security at U.S.-Mexican border crossings may be contributing factors to heroin use, especially in border cities. Risky practices among IDUs, including needle sharing and shooting gallery attendance are common, whereas perceived risk for acquiring blood borne infections is low. Although reported AIDS cases attributed to IDU in Mexico have been low, data from sentinel populations, such as pregnant women in the Mexican-U.S. border city of Tijuana, suggest an increase in HIV prevalence associated with drug use. Given widespread risk behaviors and rising numbers of blood borne infections among IDUs in Mexican-U.S. border cities, there is an urgent need for increased disease surveillance and culturally appropriate interventions to prevent potential epidemics of blood borne infections. We review available literature on the history of opium production in Mexico, recent trends in drug use and its implications, and the Mexican response, with special emphasis on the border cities of Ciudad Juarez and Tijuana.

Why are Mexican American boys so much taller now?

Delajara, Marcelo; Rodríguez-Segura, Melissa

Using NHANES data we find that the difference in average height between non-Hispanic White and Mexican American boys of ages 2-14 years has decreased 1.7 cm on average during the last quarter of the twentieth century in the United States. Our hypothesis is that the narrowing of the height gap is related to a larger gain in maternal height among Mexican Americans in relation to Whites. We estimate a child's height equation and find that on average about 38% of the reduction in the gap for boys of ages 2-5 years is attributed to this factor. The evidence of a secular trend for height is weak for the case of girls. 2010 Elsevier B.V. All rights reserved.

Constructions of Mexican American family grief after the death of a child: an exploratory study.

PubMed

Doran, Gerry; Downing Hansen, Nancy

2006-04-01

Using a collective case study ethnographic approach, nine individuals comprising three Mexican American families were interviewed about their family bereavement experiences after the death of a child. All families were Catholic, had surviving siblings, and had had three or more years to grieve their loss when interviewed. The deceased children ranged in age from 3 to 14, and all experienced sudden, traumatic, nonsuicide deaths. To provide a broader, contextual picture of their grief experiences, four individuals who supported these family members after the loss were also interviewed. Unique grief experiences were identified, and eight common themes emerged, reflecting the ways in which family members maintained their bond to the deceased: dreams, storytelling, keepsakes, sense of presence, faith-based connections, proximity connections, ongoing rituals, and pictorial remembrances. The cultural implications of family bereavement are highlighted.

The widespread and devastating nature of obsessive compulsive disorder (OCD) sharply contrasts with the paucity of research involving Mexican Americans and Mexicans who suffer from this condition. This mixed-methods preliminary study was intended to provide initial data and to pilot the procedures for a larger investigation of the cultural identification, symptomatology, health concerns, coping mechanisms, and quality of life of Mexican Americans and Mexicans with OCD living in the U.S.-Mexico border region of El Paso, Texas and Ciudad Juarez, Mexico. For the sample of six participants, whose symptoms ranged from moderate to extreme, OCD was associated with marked impairment in quality of life, particularly in terms of social functioning, an area of central importance for many Mexican Americans and Mexicans. Areas of further study were identified, with the aim of developing culturally sensitive interventions to decrease health disparities involving OCD. PMID:17917689

Context Characterizing where people die is needed to inform palliative care programs in Mexico. Objectives To determine whether access to health care influences the place of death of older Mexicans and examine the modifying effects of demographic and clinical characteristics. Methods We analyzed 2001 baseline and 2003 follow-up data from the Mexican Health and Aging Study. Cases included adults who completed the baseline interview and died before the follow-up interview and for whom a proxy interview was obtained in 2003. The main outcome variable was the place of death (hospital vs. home). The predictors of the place of death were identified using logistic regression analysis. Results The study group included 473 deceased patients; 52.9% died at home. Factors associated with hospital death were having spent at least one night in a hospital during the last year of life (odds ratio [OR]: 6.73; 95% confidence interval [CI]: 3.29, 13.78) and dying in a city other than the city of usual residence (OR: 4.68, 95% CI: 2.56, 8.57). Factors associated with home death were not having health care coverage (OR: 2.78, 95% CI: 1.34, 5.88), living in a city of less than 100,000 residents (OR: 2.44, 95% CI: 1.43, 4.17), and older age (OR: 1.03, 95% CI: 1.01, 1.05). Conclusion Older Mexicans with access to health care services were more likely to die in the hospital even after controlling for important clinical and demographic characteristics. Findings from the study may be used to plan the provision of accessible end-of-life hospital and home-based services. PMID:21146354

Epidemiology of diabetes mellitus in Mexico.

Type 2 diabetes is the main health problem in Mexico. The large and growing number of cases and the remarkable economic impact of the disease support this statement. The condition is expressed at an earlier age and at a lower body mass index in Mexican mestizos compared with the age and body mass index reported in Caucasians. In addition, Mexican mestizos have an increased susceptibility to developing diabetic nephropathy. The Mexican health system needs major adjustments in order to prevent and treat type 2 diabetes. Treatment is not currently based on the needs and expectations of the patient. As a result, it is insufficient, belated, and costly. Close to 20% of the preventable deaths in Mexico are caused by diabetes and related metabolic diseases. Even a small decrease in this rate could result in substantial savings for the Mexican healthcare system. © The Author(s) 2016.

Obesity is a critical problem among Mexican youth, but few studies have investigated associations among physical activity (PA) modes and anthropometrics in this population. This study examined associations among active commuting to school (ACS), sports or other organized PA, outdoor play, and body mass index (BMI) percentile and waist circumference (WC) among Mexican youth. Parents of school children (N = 1996, ages 6 to 14 years, 53.1% female) in 3 Mexican cities reported PA participation using the (modified) fourth grade School Physical Activity and Nutrition Survey. Trained assessors measured BMI percentile and WC in person. Parents reported that 52.3% of children engaged in ACS, 57.3% participated in sports or organized PA, and a median of 2 days in the previous week with at least 30 minutes of outdoor play. In complete case analyses (n = 857), ACS was negatively associated with BMI percentile, and outdoor play was negatively associated with WC after adjusting for school, age, sex, and income. In analyses incorporating data from multiple imputation (N = 1996), outdoor play was negatively associated with WC (all Ps < . 05). ACS and outdoor play are favorably associated with anthropometrics and may help prevent childhood obesity in Mexico. ACS and outdoor play should be priorities for increasing youth PA in Mexico.

To establish distribution frequency and demographic characteristics of salivary gland tumours (SGT) in order to identify possible risk profiles. The present report constitutes an eight year retrospective study (January 2000-August 2007). The archives of the Clinical and Experimental Pathology Laboratory (Graduate and Research Division, Dental School, National Autonomous University of Mexico) as well as archives of the Surgical Pathology Service (General Hospital, Mexico City) were subject to revision in order to select all cases where SGT tumour diagnoses were emitted. Age and gender of patients as well as SGT topography were obtained from medical records. Selected cases were classified according to location of the lesion, histological lineage and biological behaviour. 360 cases of SGT were included, 227 (67%) cases were benign tumours, while 83 cases (23%) were malignant tumours. SGT were most frequent in women with ages ranging from their 3rd to 5th decades of life. 275 tumours were located in major salivary glands, 78.9% of them were identified in the parotid gland. The most frequent location of tumours arising from minor salivary glands (33 cases, 38%) was found in the palatine glands. Tumours of epithelial lineage were the predominant histological type. The most frequent benign tumours were pleomorphic adenomas (86.1%) and papillary cystadenoma lymphomatosum (7.3%). The most frequent malignant tumours were adenoid cystic carcinomas (25%) and mucoepidermoid carcinomas (23.6%). Salivary gland tumours in Mexican population appear principally in major salivary glands of women in their 3rd to 5th decade of life.

Salivary gland tumours are an important part of the Oral and Maxillofacial Pathology, unfortunately, only few studies on these tumours have been done in Latin-American population. The aim of this study was to compare demographic data on salivary gland tumours in a Mexican sample with those previously published from Latin American and non-Latin American countries. All cases of salivary gland tumours or lesions diagnosed in our service were reviewed. Of the reviewed cases,67 were confirmed as salivary gland tumours. Out of these 64.2% were benign neoplasms, 35.8% were malignant and a slight female predominance (56.7%) was found. The most common location was palate followed by lips and floor of the mouth. Mean age for benign tumours was 40.6 years with female predominance (60.5%). Mean age for malignant tumours was 41 years and female predominance was found again. Palate followed by retromolar area were the usual locations. Pleomorphic adenoma (58.2%), mucoepidermoid carcinoma (17.9%) and adenoid cystic carcinoma (11.9%) were the more frequent neoplasms. All retromolar cases were malignant and all submandibular gland tumours were benign. We found a high proportion of salivary gland neoplasms in children. Our results showed that differences of the studied tumours among our sample and previously reported series exist. These differences can be related to race and geographical location.

Perinatal factors and type 1 diabetes-associated dysbiosis in Mexican infants.

PubMed

Mejía-León, María Esther; Calderón de la Barca, Ana María

Type 1 diabetes (T1D) is currently an autoimmune disease occurring more frequently and early in life. T1D development requires genetic predisposition and environmental factors, which influence the gut microbiota in early infancy and could increase the risk for T1D-associated autoimmunity. In Mexico there are no published microbiota studies in children <6 years old with T1D. We report two contrasting Mexican T1D cases of children <6 years of age and a third case of a healthy child prior to autoimmunity and T1D onset. Perinatal factors, feeding regimes in the first year of life and gut microbiota composition are discussed and related to the T1D onset. The three cases show a particular microbiota profile with decreased bacterial diversity as compared with healthy children, which could be related to environmental factors prior to the development of T1D and disease control. T1D infant cases presented a decreased bacterial diversity, which appeared before autoimmunity and T1D onset. Glycemic control could tend to correct the gut dysbiosis in T1D children. Prospective studies are needed to follow-up healthy children at high genetic risk to assess factors related to the microbiota structure. Copyright © 2015 Hospital Infantil de México Federico Gómez.

2014-04-01

The objective of this study is to investigate the relationship between immigration status and the patient experience of health care, diabetes self-management, and clinical outcomes among Mexican immigrants with diabetes receiving health care in two immigration sanctuary cities. We used data from the Immigration, Culture and Health Care study, a cross-sectional survey and medical record study of low-income patients with diabetes recruited from public hospitals and community clinics in the San Francisco Bay Area and Chicago. Undocumented Mexican, documented Mexican immigrants, and US-born Mexican-Americans' health care experiences, diabetes self-management, and clinical outcomes were compared using multivariate linear and logistic regressions. We found no significant differences in reports of physician communication, or in measures of diabetes management between undocumented and documented immigrants. All three groups had similar clinical outcomes in glycemic, systolic blood pressure, and lipid control. These results indicate that, at least in some settings, undocumented Mexican immigrants with diabetes can achieve similar clinical outcomes and report similar health care experiences as documented immigrants and US-born Mexican-Americans.

To evaluate the results of a lysosomal newborn screening (NBS) program in a cohort of 20,018 Mexican patients over the course of 3years in a closed Mexican Health System (Petróleos Mexicanos [PEMEX] Health Services). Using dried blood spots (DBS), we performed a multiplex tandem mass spectrometry enzymatic assay for six lysosomal storage disorders (LSDs) including Pompe disease, Fabry disease, Gaucher disease, mucopolysaccharidosis type I (MPS-I), Niemann-Pick type A/B, and Krabbe disease. Screen-positive cases were confirmed using leukocyte enzymatic activity and DNA molecular analysis. From July 2012 to April 2016, 20,018 patients were screened; 20 patients were confirmed to have an LSD phenotype (99.9 in 100,000 newborns). Final distributions include 11 Pompe disease, five Fabry disease, two MPS-I, and two Niemann-Pick type A/B patients. We did not find any Gaucher or Krabbe patients. A final frequency of 1 in 1001 LSD newborn phenotypes was established. NBS is a major public health achievement that has decreased the morbidity and mortality of inborn errors of metabolism. The introduction of NBS for LSD presents new challenges. This is the first multiplex Latin-American study of six LSDs detected through NBS. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective: To investigate the class, type, position, diagnosis and most common procedures used in the surgical removal of third molars, and evaluate the sex and age distribution in a representative sample of Mexican patients. Study Design: A retrospective descriptive study was made covering the period 1993-2008 in relation to 9148 extracted third molars in 3206 patients treated in the Dental School of Salle Bajío University, A.C. (Mexico). Patients of either sex and aged 11-59 years, with at least one third molar programmed for surgical removal, were included in the study. A descriptive statistical study was made. Results: The mean patient age was 27.6 ± 10.6 years. There were 2093 females (65.3%) and 1111 males (34.6%). In relation to the 4025 upper molars, extraction was decided for prophylactic reasons in 3827 cases (95.08%). Type A presentations were recorded in 1929 cases (47.9%), with a vertical position in 1931 teeth (48%). In relation to the 5123 lower third molars, extraction was likewise most often indicated for prophylactic reasons (4424 cases, 86.36%). A total of 2353 teeth corresponded to type A (45.9%), 2545 were class I cases (49.7%), and a mesioangular position was observed in 1850 cases (36.1%). Conclusions: The present study shows that in Mexican patients, upper third molars most often correspond to type A and class I, with a vertical position, while lower third molars predominantly correspond to type A and class I, with a mesioangular position. This information can help dental surgeons take better decisions before and after surgery, to the benefit of their patients. Key words:Third molars, retrospective review, surgical removal.

2011-02-01

The purpose of this study is to determine the relationship between nativity and nutritional behaviors and beliefs in the Mexican American population living in the South Texas border region. Mexican Americans living the border region of South Texas were sampled to assess their nutrition behaviors and beliefs. Nativity was measured as whether subjects were born in the United States or Mexico. Nutritional behaviors were measured using the SPAN and indexes were used to measure barriers to good nutrition, dietary self-efficacy, and dietary importance. OLS regression analysis was used and adjustments were made for sociodemographic factors. Differences between US-born Mexican Americans and Mexico-born Mexican Americans existed in nutritional beliefs, but not in behaviors. Mexico-born Mexican Americans reported their dietary choices as more important and reported greater food self-efficacy than their US-born Mexican American counterparts. Socioeconomic status influenced US-born Mexican Americans nutritional beliefs only and the same effect was not observed for Mexico-born Mexican Americans. Despite low levels of overall acculturation in the border region dietary beliefs still exist between immigrants and US-born Mexican Americans in dietary beliefs, but, not behaviors in US-born Mexican Americans.

Undocumented Migration and the Residential Segregation of Mexicans in New Destinations1

Hall, Matthew; Stringfield, Jonathan

2014-01-01

This study uses data from the 2000 Census and 2005–2009 American Community Survey to examine the impact of undocumented Mexican migration to new destinations on residential segregation between Mexican immigrants and native-born whites and native-born blacks. We find that Mexican-white and Mexican-black segregation is higher in new Mexican gateways than in established areas and that, for Mexican-immigrant segregation from whites, this heightened level of residential segregation in new destinations can be explained by the high presence of unauthorized Mexican immigrants living there which tends to bolster segregation between the two groups. By contrast, Mexican-immigrant segregation from native-born blacks tends to be lower in areas with larger undocumented populations, a pattern that is especially true in new destinations. Neither of these opposing effects of legal status on Mexican-immigrant segregation can be explained by compositional differences in assimilation (English ability and earnings) between documented and undocumented immigrants nor by structural variation in metropolitan areas, suggesting a unique association between legal status and segregation.

Potter, Joseph E; Hubert, Celia; White, Kari

2017-09-01

Objectives In the 1980s, policy makers in Mexico led a national family planning initiative focused, in part, on postpartum IUD use. The transformative impact of this initiative is not well known, and is relevant to current efforts in the United States (US) to increase women's use of long-acting reversible contraception (LARC). Methods Using six nationally representative surveys, we illustrate the dramatic expansion of postpartum LARC in Mexico and compare recent estimates of LARC use immediately following delivery through 18 months postpartum to estimates from the US. We also examine unmet demand for postpartum LARC among 321 Mexican-origin women interviewed in a prospective study on postpartum contraception in Texas in 2012, and describe differences in the Mexican and US service environments using a case study with one of these women. Results Between 1987 and 2014, postpartum LARC use in Mexico doubled, increasing from 9 to 19 % immediately postpartum and from 13 to 26 % by 18 months following delivery. In the US, <0.1 % of women used an IUD or implant immediately following delivery and only 9 % used one of these methods at 18 months. Among postpartum Mexican-origin women in Texas, 52 % of women wanted to use a LARC method at 6 months following delivery, but only 8 % used one. The case study revealed provider and financial barriers to postpartum LARC use. Conclusions Some of the strategies used by Mexico's health authorities in the 1980s, including widespread training of physicians in immediate postpartum insertion of IUDs, could facilitate women's voluntary initiation of postpartum LARC in the US.

To identify the cancer incidence and mortality in Mexican Social Security Institute beneficiary (MSSI-B) children during 1996-2013. Both cancer cases (n=4 728) and deaths (n=2 378) were analyzed in MSSI-B children who were registered in five states of the Mexican Republic. The incidence and mortality trends and the incidences (rate x 1 000 000 children / year) of the type of cancer, age, sex, and place of residence were obtained. For both indicators (incidence and mortality), there was a downward trend for the period of 1996-2001 and a stable trend for 2002-2013. This occurred in the overall mortality and incidence trends of the Estado de México and Chiapas and in the leukemia and the acute lymphoid subgroups. The annual overall incidence was 128 cases per 1 000 000 children. Leukemia, lymphomas, and central nervous system tumors were the principal cancer groups. Cancer mortality for the period of 2002-2013 did not diminish. Interinstitutional and/or international research should be designed to improve the care of these children.

This research evaluates the properties of a measure of culturally linked values of Mexican Americans in early adolescence and adulthood. The items measure were derived from qualitative data provided by focus groups in which Mexican Americans’ (adolescents, mothers and fathers) perceptions of key values were discussed. The focus groups and a preliminary item refinement resulted in the fifty-item Mexican American Cultural Values Scales (identical for adolescents and adults) that includes nine value subscales. Analyses of data from two large previously published studies sampling Mexican American adolescents, mothers, and fathers provided evidence of the expected two correlated higher order factor structures, reliability, and construct validity of the subscales of the Mexican American Cultural Values Scales as indicators of values that are frequently associated with Mexican/Mexican American culture. The utility of this measure for use in longitudinal research, and in resolving some important theoretical questions regarding dual cultural adaptation, are discussed. PMID:20644653

The socio-political context of migration and reproductive health disparities: The case of early sexual initiation among Mexican-origin immigrant young women

PubMed Central

Coleman-Minahan, Kate

2017-01-01

Prior research often explains the lower risk of early sexual initiation among foreign-born Mexican-origin young women by a patriarchal and sexually conservative “traditional Latino culture.” This definition overlooks structural factors such as exploitation of migrant workers, and conflates gender inequality and sexual expectations. I use an intersectional framework and the theory of gender and power to explore how gender inequality and sexual expectations are both influenced by structural factors and affect reproductive health outcomes. I integrate data from qualitative interviews with 21 first and second generation Mexican-origin women in 2013–2014 with data from discrete time hazard models with 798 Mexican-origin young women in the National Longitudinal Study of Adolescent to Adult Health. Qualitative results demonstrate that gender inequality and sexual expectations in Mexican-origin immigrant households are associated with structural factors. Gender inequality occurs more often in households with family instability, greater poverty, and among parents who migrated independently. Qualitative data also demonstrate that parental gendered expectations are sometimes at odds to what parents are actually doing in the household. Finally, contrary to assumptions that a patriarchal “traditional Latino culture” protects against early sexual initiation, qualitative and multivariate quantitative data suggest that household gender inequality increases risk of early sexual initiation. These findings challenge the utility of a culturalist approach that views culture as determining behavior to explain health disparities among immigrants and demonstrate the need to incorporate an intersectional framework that includes structural factors. This approach may reduce stereotypes and identify meaningful interventions to reduce reproductive health disparities. PMID:28324794

To compare the indicator height for age in Mexican children with Down Syndrome (DS) with two different reference patterns of growth (American and Spanish) that might be suitable for the Mexican population. A cross-sectional study was performed including 235 Mexican children and adolescents of both sexes with DS aged 45 days to 16 years enrolled in two specialized schools in the metropolitan area of Guadalajara. The dependent variables were weight/age; height/age; weight/ height and BMI. The data expressed was percentiles and the chi-square test was used to compare the distribution of the height/age index with American and Spanish reference patterns. In addition, a chi-square test was performed for the goodness of fit of the height/age index, with breakpoints lower and greater than the 50th percentile. The percentage of participants who were below the 50th percentile in the height/age index was significantly higher with the Spanish vs. the American reference pattern. The chi-square test for goodness of fit showed that the frequency of cases located below the 50th percentile in the height/age index was significantly higher with the American pattern in the age groups of 0 to 36 months (p = 0.022) and 37 to 72 months (p <0.001), but it was not significant (p = 0.225) in the older than 72 months age group. The American reference pattern is a better fit for the growth of Mexican children with DS compared with the Spanish reference pattern, and the distribution profile obtained with the standard growth and WHO reference was not suitable for the assessment of children with Down syndrome.

Cancer cases numbers are increasing worldwide positioning this disease as the second cause of mortality for both sexes. Medicinal plants have been used in the fight against cancer as the basis for drug discovery and nowadays more than 70% of anticancer drugs have a natural origin. Mexico is regarded for its cultural and biological diversity, which is reflected in the vast traditional knowledge of herbal remedies. In this review we examined herbal remedies employed in colorectal cancer treatment (CRC). The goal of this work was to gather scientific reports of plants used in Mexican traditional medicine for CRC treatment. We performed a search on scientific literature databases using as keywords: "colon cancer", "gastric cancer", "cytotoxicity", studies "in vitro and in vivo", in combination with "Mexican medicinal plants" or "Mexican herbal remedies". The selection criteria of cytotoxic activity for extracts or pure compounds was based on the National Cancer Institute of USA recommendations of effective dose 50 (ED50) of ≤20μg/mL and ≤4μg/mL, respectively. In this review we report 25 botanic families and 39 species of plants used for the treatment of colon cancer in Mexico with evidence in studies in vitro and in vivo. Medicinal plants are still a great source of novel chemical structures with antineoplastic potential as it is proven in this work. The selection criteria and activity was narrowed for methodological purposes, nevertheless, drug discovery of natural origin continues to be a highly attractive R&D strategy.

Pineda-Lucatero, A G; Trujillo-Hernández, B; Millán-Guerrero, R O; Vásquez, C

2009-03-01

To determine the characteristics and prevalence of previous child sexual abuse among a group of Mexican junior high school students. A total of 1067 adolescents of both genders were selected to fill out a survey about child sexual abuse. The prevalence of child sexual abuse was 18.7% (n = 200). It was more frequent in girls (58%) than in boys (42%). Sexual abuse involved physical contact in 75% of those cases reporting abuse. The aggressors were neighbours (50.3%), relatives (36.8%) and strangers (13.9%). Abuse was committed through deception in 90% of the cases and involved physical mistreatment in 10% of the cases. Of the victims, 14.4% had spoken about the problem and 3.7% had taken legal action. And 9.6% of those surveyed stated that they required psychological counselling. In the population studied, the prevalency of child sexual abuse was greater than that reported in Mexico City (4.3-8.4%), although it was similar to that found in the Spanish child population (15-23%). The risk of sexual abuse is greater for girls and the principal aggressors are male neighbours, family friends and relatives; the abuse is committed in the home of the aggressor or the victim and very few cases are reported to the authorities.

2018-02-01

Non-alcoholic fatty liver disease (NAFLD) is the accumulation of extra fat in liver cells not caused by alcohol. Elevated transaminase levels are common indicators of liver disease, including NAFLD. Previously, we demonstrated that PNPLA3 (rs738409), LYPLAL1 (rs12137855), PPP1R3B (rs4240624), and GCKR (rs780094) are associated with elevated transaminase levels in overweight/obese Mexican adults. We investigated the association between 288 SNPs identified in genome-wide association studies and risk of elevated transaminase levels in an admixed Mexican-Mestizo sample of 178 cases of NAFLD and 454 healthy controls. The rs2896019, rs12483959, and rs3810622 SNPs in PNPLA3 and rs1227756 in COL13A1 were associated with elevated alanine aminotransferase (ALT, ≥40IU/L). A polygenic risk score (PRS) based on six SNPs in the ADIPOQ, COL13A1, PNPLA3, and SAMM50 genes was also associated with elevated ALT. Individuals carrying 9-12 risk alleles had 65.8% and 48.5% higher ALT and aspartate aminotransferase (AST) levels, respectively, than those with 1-4 risk alleles. The PRS showed the greatest risk of elevated ALT levels, with a higher level of significance than the individual variants. Our findings suggest a significant association between variants in COL13A1, ADIPOQ, SAMM50, and PNPLA3, and risk of NAFLD/elevated transaminase levels in Mexican adults with an admixed ancestry. This is the first study to examine high-density single nucleotide screening for genetic variations in a Mexican-Mestizo population. The extent of the effect of these variations on the development and progression of NAFLD in Latino populations requires further analysis. Copyright © 2018 Elsevier Inc. All rights reserved.

2013-02-01

Recent genome wide association studies (GWAS) and previous positional linkage studies have identified more than 50 single nucleotide polymorphisms (SNPs) associated with obesity, mostly in Europeans. We aimed to assess the contribution of some of these SNPs to obesity risk and to the variation of related metabolic traits, in Mexican children. The association of six European obesity-related SNPs in or near FTO, NPC1, ENPP1, NEGR1, GNPDA2 and MC4R genes with risk of obesity was tested in 1,463 school-aged Mexican children (N(cases) = 514; N(controls) = 949). We also assessed effects of these SNPs on the variation of body mass index (BMI), fasting serum insulin levels, fasting plasma glucose levels, total cholesterol and triglyceride levels, in a subset of 1,171 nonobese Mexican children. We found a significant effect of GNPDA2 rs10938397 on risk of obesity (odds ratio [OR] = 1.30; P = 1.34 × 10-3). Furthermore, we found nominal associations between obesity risk or BMI variation and the following SNPs: ENPP1 rs7754561, MC4R rs17782313 and NEGR1 rs2815752. Importantly, the at-risk alleles of both MC4R rs17782313 and NPC1 rs1805081 showed significant effect on increased fasting glucose levels (β = 0.36 mmol/L; P = 1.47 × 10(-3)) and decreased fasting serum insulin levels (β = -0.10 μU/mL; P = 1.21 × 10(-3)), respectively. Our present results suggest that some obesity-associated SNPs previously reported in Europeans also associate with risk of obesity, or metabolic quantitative traits, in Mexican children. Importantly, we found new associations between MC4R and fasting glucose levels, and between NPC1 and fasting insulin levels.

The aim of this study was to evaluate if polymorphisms of APLN and APLNR genes may play a role as susceptibility markers for hypertension in a group of Mexican-Mestizo patients. A case-control study was carried out including normotensive and hypertensive individuals. For these, two polymorphisms of APLN (rs3761581 and rs56204867) and two of APLNR () genes were genotyped by 5' exonuclease TaqMan assay in 400 normotensive individuals and 383 patients. The results showed that, under an additive model adjusted by BMI, HDL, triglycerides, glucose and family history of essential hypertension, the rs7119375 and rs10501367 polymorphisms of APLNR gene were associated significantly with a decreased risk of essential hypertension (P=0.039 and P=0.029, respectively). Besides, the haplotypes analysis of these polymorphisms showed that H1 haplotype was associated with an increased risk of essential hypertension (P=0.026), while the H2 haplotype was associated with a decreased risk (P=0.032). Contrary, the rs3761581 and rs56204867 polymorphisms of APLN gene were not associated with essential hypertension (P=0.1707 and P=0.0769, respectively). The data suggest that APLNR rs7119375 and rs10501367 are associated with a decreased risk of essential hypertension in our Mexican-Mestizo studied group, but further studies are warranted.

2013-01-01

In comparison to non-Hispanic whites, a number of health-care disparities, including poor oral health, have been identified among Hispanics in general and Mexican Americans in particular. We hypothesized that Mexican Americans with chronic kidney disease (CKD) would have higher prevalence of chronic periodontitis compared with Mexican Americans with normal kidney function, and that the level of kidney function would be inversely related to the prevalence of periodontal disease. We examined this hypothesis using the National Health and Nutrition Examination Survey 1988-1994 (NHANES III) data set. We followed the American Academy of Periodontology/Center for Disease Control and Prevention case definition for periodontitis. Glomerular filtration rate was estimated using the CKD-Epidemiology equation for Hispanic populations. The classification to CKD stages was based on the National Kidney Foundation Kidney Disease Outcomes Quality Initiative. Periodontitis prevalence increased across the kidney function groups showing a statistically significant dose-response association (P<0.001). Mexican Americans with reduced kidney function were twofold more likely to have periodontitis compared with Mexican Americans with normal kidney function after adjusting for potential confounders such as smoking, diabetes, and socioeconomic status. Multivariate adjusted odds ratio for periodontitis significantly increased with 1, 5, and 10 mL/minute estimated glomerular filtration rate reduction from the mean. This is the first report, to the best our knowledge, that showed an increase of periodontitis prevalence with decreased kidney function in this population. © 2012 American Association of Public Health Dentistry.

We hypothesized that Mexican-Americans with Chronic Kidney disease (CKD) would have higher prevalence of chronic periodontitis compared to Mexican Americans with normal kidney function, and that the level of kidney function would be inversely related to the prevalence of periodontal disease. Method We examined this hypothesis using the National Health and Nutrition Examination Survey 1988–1994 (NHANES III) dataset. We followed the American Academy of Periodontology (AAP)/Center for Disease Control and Prevention (CDC) case definition for periodontitis. Glomerular filtration rate was estimated using the CKD-Epidemiology (EPI) equation for Hispanic populations. The classification to CKD stages was based on the National Kidney Foundation Kidney Disease Outcomes Quality Initiative. Results Periodontitis prevalence increased across the kidney function groups showing a statistically significant dose-response association (p<0.001). Mexican Americans with reduced kidney function were 2-fold more likely to have periodontitis compared to Mexican Americans with normal kidney function after adjusting for potential confounders such as smoking, diabetes and socioeconomic status. Multivariate adjusted Odds Ratio for periodontitis significantly increased with 1, 5 and 10 mL/minute eGFR reduction from the mean.

Mexico has cultivated opium poppy since before the 1900’s and has been an important transit route for South American cocaine for decades. However, only recently has drug use, particularly injection drug use, been documented as an important problem. Heroin is the most common drug used by Mexican injection drug users (IDUs). Increased cultivation of opium poppy in some Mexican states, lower prices for black tar heroin and increased security at U.S.-Mexican border crossings may be contributing factors to heroin use, especially in border cities. Risky practices among IDUs, including needle sharing and shooting gallery attendance are common, whereas perceived risk for acquiring blood borne infections is low. Although reported AIDS cases attributed to IDU in Mexico have been low, data from sentinel populations, such as pregnant women in the Mexican-U.S. border city of Tijuana, suggest an increase in HIV prevalence associated with drug use. Given widespread risk behaviors and rising numbers of blood borne infections among IDUs in Mexican-U.S. border cities, there is an urgent need for increased disease surveillance and culturally appropriate interventions to prevent potential epidemics of blood borne infections. We review available literature on the history of opium production in Mexico, recent trends in drug use and its implications, and the Mexican response, with special emphasis on the border cities of Ciudad Juarez and Tijuana.

Savani, Krishna; Alvarez, Ayme; Mesquita, Batja; Markus, Hazel Rose

2013-01-01

Two studies investigate whether interpersonally engaging emotions--those that bring the self closer to others (e.g., affection, shame)--are central to the model of self and relationships prevalent in Mexican cultural contexts. Study 1 demonstrated that compared to people in European American contexts, people in Mexican contexts were more likely to report experiencing interpersonally engaging emotions and less likely to report experiencing interpersonally disengaging emotions. Study 2 found that interpersonally engaging emotions had a substantial influence on performance motivation in Mexican contexts--Mexican participants solved more word search puzzles after recalling instances in which they experienced positive interpersonally engaging emotions, and fewer after recalling negative interpersonally disengaging emotions; in contrast, there were no differences by condition for European Americans. These findings significantly extend previous research by documenting the implications of relational concerns (e.g., simpatia, personalismo) for emotion and motivation in Mexican contexts, and are the first to demonstrate the motivational effects of interpersonally engaging emotions.

Mexican-heritage preadolescents' ethnic identification and perceptions of substance use.

2009-01-01

This paper examines the relationship between ethnic identification and substance use for 1,346 Mexican-heritage preadolescents in a National Institute on Drug Abuse-funded study in Phoenix, Arizona (2004-2005). Participants ranged from 9 to 13 years old, 49% reported their gender as male, 33% self-identified as Mexican, and 67% as Mexican American, and 91% of the students reported taking part in the free or reduced-price lunch program. Questionnaire responses were analyzed by fitting regression models. Analyses showed that ethnic identification may play a protective role, with stronger ethnic identification related to more antidrug norms, less positive drug expectations, stronger refusal efficacy, and less intent to use substances. While gender did not significantly moderate the relationships, ethnic identification appears more broadly related to antisubstance-use norms for Mexican-born than U.S.-born participants. This study presents important implications for substance-use prevention research among Mexican heritage preadolescents. Finally, limitations of the study are noted.

2014-01-01

Objectives This study compares various dimensions of physical and emotional health between older Mexican-origin individuals in the United States and in Mexico. Method The samples are drawn from the Mexican Health and Aging Study (MHAS) and the Hispanic Established Epidemiologic Study of the Elderly (H-EPESE) and include 3,875 Mexican residents with no history of residence in the United States and 2,734 Mexican-origin individuals 65 and older who live in the southwestern United States. Results Both immigrant and native-born Mexican-origin elders in the United States report more chronic conditions than elderly Mexicans, but they report fewer symptoms of psychological distress. Longer residence in the United States is associated with higher body mass index scores. Discussion The discussion addresses the possibility that access to care influences reports of diagnosed conditions and touches on issues of comparability in cross-cultural research and the difficulty in clearly distinguishing cultural and system-level factors in the production and measurement of health.

Prado-León, L R; Avila-Chaurand, R; González-Muñoz, E L

2001-08-01

This paper presents the results of an anthropometric survey conducted on male and female Mexican primary school children age 6-11 years in the metropolitan area of the city of Guadalajara. A set of 50 body dimensions was taken based on international standards. The sample consisted of 4758 children (boys and girls). The anthropometric measurements were compared to those of American, Cuban and Mexican children. The results indicate that the body dimensions of Mexican children from this study are different from those of American, Cuban, and other Mexican children, probably due to ethnic differences and the time lapse between the different studies. It is considered that the 50 parameters are necessary for the design of school furniture, fittings and equipment in order to minimize musculoskeletal, visual, and circulatory problems resulting from using those badly designed elements.

The proband in this study was a 4-year-old Mexican girl with Blau syndrome. She and her affected family members had skin rash and arthritis but no uveitis. Exome sequencing and DNA direct sequencing from blood samples revealed a novel nucleotide-binding oligomerization domain-containing protein 2 gene mutation in the affected family members. This study is the first report of a Mexican family with Blau syndrome showing good infliximab treatment response. The novel mutation in the nucleotide-binding oligomerization domain-containing protein 2 gene (c.1808A>G) enriches the mutation spectrum in Blau syndrome. This family represents one of the few cases of autosomal Blau syndrome with no uveitis; because of phenotype variability, it is important to recognize Blau syndrome's clinical spectrum and recommend genetic consultation. © 2018 Wiley Periodicals, Inc.

2006-01-01

Central to the development of culturally competent violence prevention programs for Hispanic youth is the development of psychometrically sound violence risk and outcome measures for this population. A study was conducted to determine the psychometric properties of two commonly used violence measures, in this case for Mexican American adolescent females. The Conflict Tactics Scales (CTS2) and the Past Feelings and Acts of Violence Scale (PFAV) were analyzed to examine their interitem reliability, criterion validity, and discriminant validity. A sample of 150 low-risk and 150 high-risk adolescent females was studied. Discriminant validity was indicated by the perpetrator negotiation scale and by the victim psychological aggression and sexual coercion scales of the CTS2 and the PFAV. Analysis indicates that the CTS2 scales and the PFAV demonstrate adequate reliability, whereas strong criterion validity was evidenced by eight of the CTS2 scales and the PFAV.

Previous studies suggest that favorable pregnancy outcomes among Mexican immigrant women in the United States may be attributed to a protective sociocultural orientation, but few have explored the attitudes and values that shape Mexican women's perceptions of motherhood. This exploratory study examines orientation towards motherhood among Mexican and Mexican-origin women living in Mexico and the United States and their perceptions of their male partners' attitudes and roles. Focus groups were conducted with 60 pregnant low-income women in rural and urban communities in Mexico with high rates of migration to the US, among immigrant communities in rural and urban California and with US-born women of Mexican descent (Mexican Americans) in urban California. Notable differences were observed between women in Mexico and the US and between immigrant and Mexican American women in California as more women articulated life plans. Life plans seemed to reflect both processes of individuation and changing gender roles. While participants in Mexico largely abided by the conventional discourse on motherhood and domesticity, immigrants in California alternated between this ethos and the discourse of working mother, depending on financial resources. In contrast, Mexican American participants assumed multiple roles. These differing orientations may be linked to other factors, including fertility control, the amount and type of partner support, and stress during pregnancy.

We studied the X-STR decaplex system in 529 DNA female samples of Mexican populations from five geographic regions. Allele frequencies and forensic parameters were estimated in each region and in the pooled Mexican population. Genotype distribution by locus was in agreement with Hardy-Weinberg expectations in each Mexican population sample. Similarly, linkage equilibrium was demonstrated between pair of loci. Pairwise comparisons and genetic distances between Mexican, Iberoamerican and one African populations were estimated and graphically represented. Interestingly, a non-significant interpopulation differentiation was detected (Fst = 0.0021; p = .74389), which allows using a global Mexican database for forensic interpretation of X-STR genotypes.

The gene for patatin-like phospholipase domain containing 3 (PNPLA3) is associated with nonalcoholic fatty liver disease (NAFLD) development. We previously found that Mexican indigenous population had the highest frequency reported of the PNPLA3 148M risk allele. Further, we observed a relationship between M148M genotype with elevated ALT levels in individuals with normal weight, overweight and obese. We sought to investigate whether PNPLA3 polymorphism is associated with NAFLD development in Mexicans. We enrolled 189 Mexican patients with NAFLD and 201 healthy controls. Anthropometric, metabolic, and biochemical variables were measured, and rs738409 (Ile148Met substitution) polymorphism was genotyped by sequencing. Logistic regression analysis, using a recessive model, suggested that PNPLA3 polymorphism in Mexican population is significantly associated (OR = 1.711, 95% CI: 1.014-2.886; P = 0.044) with NAFLD. The PNPLA3 gene is associated with NAFLD in Mexican population. More studies are required to explain the high prevalence of PNPLA3 polymorphism in Mexican-Americans, Mexican-Indians, and Mexican-Mestizos.

Mexican immigrant mothers' expectations for children's health services.

Clark, Lauren; Redman, Richard W

2007-10-01

Women of Mexican descent living in the United States raise children who use health care services. What do immigrant Mexican mothers expect from children's health care services? And how do their expectations for children's health services compare to acculturated Mexican American mothers' expectations? This focused ethnographic study, based on repeated interviews with 28 mothers of varying acculturation levels, describes their expectations and experiences with children's health care services in the United States. Findings support a shared core of expectations for both Mexican immigrant and Mexican American mothers, and differences in health care access and financing, time spent in health care encounters, and cultural and linguistic expectations for care. Health care providers can use this information to approach Mexican-descent mothers and children with their expectations in mind, and craft a negotiated plan of care congruent with their expectations.

Church-Based Social Relationships, Belonging, and Health Among Older Mexican Americans

The purpose of this study is to explain how church-based emotional support influences the health of older Mexican Americans. This issue is evaluated with a theoretical model that contains the following core linkages: (1) older Mexican Americans who go to church more often will be more likely to receive emotional support from fellow church members; (2) older Mexican Americans who receive more support from their fellow church members will be more likely to feel they belong in their congregation; (3) older Mexican Americans who feel they belong in their congregation are likely to have a stronger sense of personal control; and (4) older Mexican Americans who have a stronger sense of personal control are likely to enjoy better health. Data from a recent nationwide survey of older Mexican Americans provide support for each of these relationships. PMID:21687808

Case series Patient: — Final Diagnosis: Ellis van Creveld syndrome Symptoms: Conical teeth • polydactyly • short stature Medication: — Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Rare disease Background: Ellis-van Creveld syndrome is an autosomal recessive chondro-ectodermal dysplasia characterized by disproportionate short stature, limb shortening, narrow chest, postaxial polydactyly and dysplastic nails and teeth. In addition, 60% of cases present congenital heart defects. Ellis-van Creveld syndrome is predominantly caused by mutations in the EVC or EVC2 (4p16) genes, with only a few cases caused by mutations in WDR35. Case Report: Here, we report on two Mexican families with patients diagnosed with Ellis-van Creveld syndrome. Family 1 includes four patients: three females of 15, 18, and 23 years of age and a 7-year old male. Family 2 has only one affected newborn male. All patients exhibited multiple features including hypodontia, dysplastic teeth, extra frenula, mild short stature, distal limb shortening, postaxial polydactyly of hands and feet, nail dystrophy, and knee joint abnormalities. Only two patients had an atrial septal defect. In all cases, molecular analysis by Sanger sequencing identified the same homozygous mutation in exon 12 of EVC, c.1678G>T, which leads to a premature stop codon. Conclusions: The mutation c.1678G>T has been previously reported in another Mexican patient and it appears to be a recurrent mutation in Mexico which could represent a founder mutation. The large number of patients in this case allows the clinical variability and spectrum of manifestations present in individuals with Ellis-van Creveld syndrome even if they carry the same homozygous mutation in a same family.

In Mexico, due to the high rates of diabetes, overweight, and obesity, there has also been noted an increased newborn weight, which may be contributing to the elevated incidence rate of childhood acute leukemia (AL). We conducted a case-control study in public hospitals of Mexico City aimed to know whether a greater weight at birth is associated with a higher risk of developing leukemia. We included incident cases with acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) diagnosed between 2010 and 2015. Controls were frequency-matched to the cases by age, sex, and health institution. Logistic regression analysis was performed adjusting risks by child's sex, overcrowding index, birth order, and mother's age at the time of pregnancy. Adjusted odds ratios (aORs) and 95% confidence intervals were calculated. A total of 1455 cases and 1455 controls were included. An evident association between ALL and child's birthweight ≥2500 g was found (aOR 2.06; 95% CI: 1.59, 2.66) and also, in those with birthweight ≥3500 g (aOR 1.19; 95% CI: 1.00, 1.41). In AML patients with birthweight ≥2500 g and ≥3500 g, an aOR of 1.77 (95% CI: 1.07, 2.94) and 1.42 (95% CI: 1.03-1.95) was observed, respectively. No association was noticed with either type of AL and a birthweight ≥4000 g. To sum up, we found a moderate association between not having a low birthweight and an increased risk of acute leukemias. Birthweight ≥3500 g was also a risk factor for both types of leukemia. This suggests that a greater birthweight may increase the risk of acute leukemias in Mexican children. © 2018 The Authors.

Davila, Y R; Brackley, M H

1999-01-01

Anecdotal information suggests that, for Hispanic women who are involved with abusive partners, condom use request as an HIV/AIDS sexual risk-reduction behavior may expose the women to risk of both abuse and HIV/AIDS. A qualitative study explored barriers to condom negotiation for HIV/AIDS prevention among Mexican and Mexican American women in abusive relationships. A convenience sample of 14 Mexican and Mexican American women was recruited from a battered women's shelter. A demographic form, a domestic violence assessment form, and audiotaped responses to a semistructured interview guide were used to collect data. Descriptive statistics were used to describe the sample. Audiotaped interviews were transcribed verbatim and submitted to content analysis, which revealed past and present themes of physical, psychological, and sexual abuse of Mexican and Mexican American women who requested condom use by their male sexual partners. Also identified by content analysis was the influence of men's power on women's public, private, and sexual interactions.

Genome-Wide Analysis of SNPs Is Consistent with No Domestic Dog Ancestry in the Endangered Mexican Wolf (Canis lupus baileyi).

Fitak, Robert R; Rinkevich, Sarah E; Culver, Melanie

2018-05-11

The Mexican gray wolf (Canis lupus baileyi) was historically distributed throughout the southwestern United States and northern Mexico. Extensive predator removal campaigns during the early 20th century, however, resulted in its eventual extirpation by the mid 1980s. At this time, the Mexican wolf existed only in 3 separate captive lineages (McBride, Ghost Ranch, and Aragón) descended from 3, 2, and 2 founders, respectively. These lineages were merged in 1995 to increase the available genetic variation, and Mexican wolves were reintroduced into Arizona and New Mexico in 1998. Despite the ongoing management of the Mexican wolf population, it has been suggested that a proportion of the Mexican wolf ancestry may be recently derived from hybridization with domestic dogs. In this study, we genotyped 87 Mexican wolves, including individuals from all 3 captive lineages and cross-lineage wolves, for more than 172000 single nucleotide polymorphisms. We identified levels of genetic variation consistent with the pedigree record and effects of genetic rescue. To identify the potential to detect hybridization with domestic dogs, we compared our Mexican wolf genotypes with those from studies of domestic dogs and other gray wolves. The proportion of Mexican wolf ancestry assigned to domestic dogs was only between 0.06% (SD 0.23%) and 7.8% (SD 1.0%) for global and local ancestry estimates, respectively; and was consistent with simulated levels of incomplete lineage sorting. Overall, our results suggested that Mexican wolves lack biologically significant ancestry with dogs and have useful implications for the conservation and management of this endangered wolf subspecies.

Environmental and occupational exposure to asbestos in Mexico in the past has been a cause of deaths and health damages. Its magnitude is unknown to date. Our objective was to identify the proportion of cases of malignant pleural mesothelioma (MPM) that can be attributed to and occupational exposure to asbestos. We carried out a case-control study of MPM in 472 workers insured by the Mexican Institute of Social Security, all Valley of Mexico residents, with 119 incident cases and 353 controls. Cases were histologically confirmed. Participants were questioned concerning their occupational history and sociodemographic data. Assignment to one of the four exposures was performed qualitatively by an expert hygienist. Odds ratios (ORs) and attributable risks (ARs) were calculated using a non-conditional logistic regression model. A total of 80.6% of cases and 31.5% of controls had occupational exposure to asbestos. ORs were adjusted for age and gender and by exposure category, and exhibited an increase with probability of exposure as follows: 3.7(95% CI 1.3-10.4) for the likely category and 14.3(95% CI 8-26) for the certain category; AR in the group occupationally exposed to asbestos was 83.2%, and the population AR was 44%. Our results show that the relationship between industrial uses of all forms of asbestos is generating an increase in mesothelioma-related diseases and deaths among Mexican workers. As a public health policy, Mexico should prohibit the use of asbestos in all production processes with the aim of controlling the epidemic and preventing the occurrence of new cases of MPM. 2009 Wiley-Liss, Inc.

Worldwide, the suicide rate is decreasing. To examine changes in the rates of completed suicide in the Mexican population from 2003 to 2012, we analyzed these changes according to: (i) the method of suicide; (ii) age group and (iii) gender. The data analyzed were obtained from governmental organizations from the State of Tabasco, Mexico. The data provided 1836 cases of subjects born and residing in Tabasco, who completed suicide in this state. Suicide by hanging was a common choice of suicide method for Mexicans. The rate of suicide by hanging increased from 5.80 to 6.49 per 100,000 persons between 2003 and 2012, a rate percentage increase of 11.89%. Hanging was found to be the most common choice of suicide in the Mexican population, probably because the materials required are easily available and the method does not require complicated techniques, especially in the 55-64 age group. Strategies for prevention and intervention should be developed for the Mexican population considering suicide rates by age group and gender.

A large number of Mexican migrants are deported to Mexico and released in the North Mexican border region every year. Despite their volume and high vulnerability, little is known about the level of HIV infection and related risk behaviors among this hard-to-reach population. We conducted a cross-sectional, probability survey with deported Mexican migrants in Tijuana, Mexico (N=693) and estimated levels of HIV infection and behavioral risk factors among this migrant flow. The sample and population estimated rates of HIV for deported males were 1.23% and 0.80%, respectively. No positive cases were found among the female sample. We found high lifetime rates of reported sexually transmitted infections (22.3%) and last 12-months rates of unprotected sex (63.0%), sex with multiple sexual partners (18.1%), casual partners (25.7%), and sex workers (8.6%), compared to U.S. and Mexico adults. HIV prevention, testing, and treatment programs for this large, vulnerable, and transnational population need to be implemented in both the U.S. and Mexico. PMID:22562390

Farmer, A

2000-06-01

This paper characterizes the Mexican abortion laws using the case of a girl aged 14 years, Paulina Ramirez Jacinta, who was raped, became pregnant, and chose to terminate the unwanted pregnancy, yet was denied an abortion. This case clearly showed that Mexican abortion law, despite its legality, is highly restrictive in nature and, in a way, violated the human rights of Paulina. Even though it permits first-trimester abortion procedures for rape victims or women whose lives are endangered by the pregnancy, many pregnant women still resort to illegal abortion. To further aggravate the restrictive nature of the law, Baja California state Rep. Martin Dominguez Rocha made a proposal to eliminate the rape exception in the state's penal code. The case of Paulina will be handled by the lawyers at the Center for Reproductive Law and Policy in order to arrive at a settlement favorable to Paulina.

In northeastern Mexican population prevalence of positive cutaneous reaction to coccidioidin varies from 30 to 49%. Pregnancy is a risk factor for disseminated coccidioidomycosis. 1) To describe the clinical spectrum of coccidioidomycosis in four women who acquired the disease during pregnancy or puerperium. 2) To discuss the autopsy findings. 3) To review the medical literature. From 1983 to 2000, files of the Pathology Department of a reference tertiary hospital in northeastern Mexico were reviewed. Four cases of 4,598 autopsies corresponded to pregnant women with coccidioidomycosis. Clinical and autopsy charts, and the histological material were studied. Clinical spectrum included a septicemia case with fetal lost, an atypical pneumonia, a chronic meningitis with neuropsychiatric alterations and a patient with hypertensive pregnancy disease with secondary renal insufficiency and repeated episodes of pneumonia. All patients at autopsy showed multiple granulomas with abundant mycotic spherules. Lung involvement included bilateral 2-10 mm nodules. In pregnant women of endemic areas or who had traveled to these zones during pregnancy, coccidioidomycosis should be considered in the differential diagnosis of febrile syndrome with pneumonia, specially if it is accompanied of bilateral nodular infiltrates in lung, with or without erythema nodosum or meningitis.

To investigate the relationship between the advantage ear (cerebral hemisphere) of Spanish-speaking Mexican learners and the third Chinese tone. Third tone Chinese vowel syllables were used as experimental materials with dichotic listening technology to test the Spanish-speaking Mexican Chinese learners (20-32 years old) who studied Chinese about 20 h. In terms of error rates to identify the third Chinese tone, the Spanish-speaking Mexican Chinese learners's reaction to the third tone suggested that their left ears were the advantageous ear (the right cerebral hemisphere) (Z=-2.091, P=0.036). The verbal information of tones influenced the perception of Mexican Chinese learners' mandarin tones. In the process of learning mandarin tones, Mexican Chinese learners gradually formed the category of tones.

The activation of innate immunity is central to the manifestation of sepsis, and toll-like receptor (TLR) 4 plays an important role in this activation process. The 299G and 399I alleles of TLR4 have been linked with an increased risk of Gram-negative bacteria (GNB) infections and septic shock in some populations. This case-control study evaluated the prevalence of D299G/T399I polymorphisms in Mexican patients with IAI and/or pneumonia and in healthy controls. Genotyping revealed that 1 in 44 patients (2.3%; CI 95%: 0.05-12.0%) and 4 in 126 controls (3.2%; CI 95%: 0.9-7.9%) were heterozygous for both the D299G and T399l polymorphisms (OR: 0.71, CI 95%: 0.01-7.44, p = NS), confirming the co-segregation of these alleles in this population. Furthermore, the patients with a GNB infection and severe sepsis were not carriers of the risk alleles. In summary, this report shows that the frequency of the D299G and T399I polymorphisms in Mexican-Mestizos is lower than anticipated in comparison with other ethnic groups, emphasizing the variable distribution of TLR4 polymorphisms among different populations. Consequently, this study was not able to detect associations between TLR4 polymorphisms and sepsis in this population. Copyright © 2013 Elsevier B.V. All rights reserved.

Health economic assessment of universal immunization of toddlers against Hepatitis A Virus (HAV) in Mexico

Hepatitis A virus (HAV) has shifted from high to intermediate endemicity in Mexico, which may increase the risk of clinically significant HAV infections in older children, adolescents and adults. The objective of this study was to evaluate the cost-utility of single-dose or 2-dose universal infant HAV vaccination strategy in Mexico, compared with no vaccination. A previously published dynamic model estimated the expected number of HAV cases with each strategy, and a decision model was used to estimate the costs and quality-adjusted life-years (QALYs) expected with each strategy. The time horizon was 25 years (2012–2036) and the base case analysis was conducted from the perspective of the Mexican public health system. Costs and QALYs after the first year were discounted at 5% annually. Input data were taken from national databases and published sources where available. The single-dose HAV vaccination strategy had an incremental cost-utility ratio (ICUR) of Mexican peso (MXN) 2,270 per QALY gained, compared with no vaccination. The two-dose strategy had an ICUR of MXN 14,961/QALY compared with no vaccination, and an ICUR of MXN 78,280/QALY compared with the single-dose strategy. The estimated ICURs were below the threshold of 1 x Mexican gross domestic product per capita. When indirect costs were included (societal perspective), the single-dose HAV vaccination strategy would be expected to improve health outcomes and to be cost-saving. This analysis indicates that routine vaccination of toddlers against HAV would be cost-effective in Mexico using either a single-dose or a 2-dose vaccination strategy.

To determine hip fracture prevalence and direct healthcare costs in elderly users of the reference hospitals of the Mexican Institute of Social Insurance (IMSS by spanish initials) and Mexican Oils (PEMEX by spanish initials), from Villahermosa, Tabasco, Mexico, during 2009. This is a cross-sectional study. The information was based on the registers of surgical interventions and institutional reports of the elderly inpatients who had a registered attention in their institution. Descriptive statistical analysis was performed considering the following variables: age, gender, hip fracture type, occurrence month, direct healthcare cost. Out of 10,765 records of hospitalized elderly, 57 hip fracture cases were found (33 in the IMSS and 24 in PEMEX). Hip fracture prevalence was 0.5%, (IMSS 1.1% and PEMEX 0.3%), being more frequent in women and older than 69. The most frequent fracture type was the femur neck one (78.9%). The estimated cost of healthcare in the hospital per patient was USD 5,803 in the IMSS and USD 11,800 in PEMEX. The hip fracture prevalence was higher in the IMSS users. Estimated healthcare costs per patient were higher than the reported in other institutions of the of the mexican health national system.

The 12.4 million Mexican migrants in the United States (US) face considerable barriers to access health care, with 45% of them being uninsured. The Affordable Care Act (ACA) does not address lack of insurance for some immigrants, and the excluded groups are a large proportion of the Mexican-American community. To redress this, innovative forms of health insurance coverage have to be explored. This study analyses factors associated with willingness to pay for cross-border, bi-national health insurance (BHI) among Mexican immigrants in the US. Surveys were administered to 1,335 Mexican migrants in the Mexican Consulate of Los Angeles to assess their health status, healthcare utilization, and willingness to purchase BHI. Logistic regression was used to identify predictors of willingness to pay for BHI. Having a job, not having health insurance in the US, and relatives in Mexico attending public health services were significant predictors of willingness to pay for BHI. In addition, individuals identified quality as the most important factor when considering BHI. In spite of the interest for BHI among 54% of the sampled population, our study concludes that this type of coverage is unlikely to solve access to care challenges due to ACA eligibility among different Mexican immigrant populations.

To further understanding of the genetic basis of type 2 diabetes (T2D) susceptibility, we aggregated published meta-analyses of genome-wide association studies (GWAS), including 26,488 cases and 83,964 controls of European, east Asian, south Asian and Mexican and Mexican American ancestry. We observed a significant excess in the directional consistency of T2D risk alleles across ancestry groups, even at SNPs demonstrating only weak evidence of association. By following up the strongest signals of association from the trans-ethnic meta-analysis in an additional 21,491 cases and 55,647 controls of European ancestry, we identified seven new T2D susceptibility loci. Furthermore, we observed considerable improvements in the fine-mapping resolution of common variant association signals at several T2D susceptibility loci. These observations highlight the benefits of trans-ethnic GWAS for the discovery and characterization of complex trait loci and emphasize an exciting opportunity to extend insight into the genetic architecture and pathogenesis of human diseases across populations of diverse ancestry.

In México the first human chronic chagasic case was recognized in 1940. In spite of an increasing number of cases detected since that time, Chagas disease in México has been poorly documented. In the present work we studied 617 volunteers subjects living in high and low endemic regions of Trypanosoma cruzi infection with seroprevalence of 22% and 4% respectively. Hemoculture performed in those seropositive subjects failed to demonstrate circulating parasites, however polymerase chain reaction identified up to 60% of them as positives. A higher level of anti-T. cruzi antibodies was observed in seropositive residents in high endemic region, in spite of similar parasite persistence (p < 0.05). On standard 12 leads electrocardiogram (ECG) 20% to 22% seropositive individuals from either region showed right bundle branch block or ventricular extrasystoles which were more prevalent in seropositive than in seronegative individuals (p < 0.05). In conclusion, the frequency or type of ECG abnormality was influenced by serologic status but not by endemicity or parasite persistence. Furthermore, Mexican indeterminate patients have a similar ECG pattern to those reported in South America.

This is a case study of Celeste, postulant in a Roman Catholic convent in Mexico who experienced frequent episodes of leaving her body to commune with God. During these experiences, Celeste felt immersed in an ;incredibly beautiful profound silence' where ;time and space were broken.' But as much as Celeste craved these experiences, they also alarmed her; she was acutely aware that they might be indicative of psychological or neurological dysfunction. This article chronicles Celeste's struggles to make sense of her experiences in light of competing explanatory models. Her ultimate resolution suggests intriguing new directions for transcultural psychiatric research.

Few studies have addressed the specific health care needs of Mexican-American adolescents. This 2-year study assessed the routine health care needs and incidence of chronic illness among 279 Mexican-American, 233 white, and 333 black indigent adolescents enrolled in a vocational training program. Mexican-Americans were more likely to have a positive purified protein derivative tuberculin test and acne/eczema requiring treatment. Blacks were more likely to have incomplete immunizations and thyroid disorders, while whites were more likely to have musculoskeletal conditions and require family planning services and psychiatric intervention for mental health disorders. Although no difference in incidence of chronic illness was noted, our data suggests that routine health care needs may differ among indigent Mexican-American, white, and black adolescents.

Objectives Investigate the “salmon-bias” hypothesis, which posits that Mexicans in the U.S. return to Mexico due to poor health, as an explanation for the Hispanic health paradox in which Hispanics in the United States are healthier than might be expected from their socioeconomic status. Method Sample includes Mexicans age 50 or above living in the U.S. and Mexico from the 2003 Mexican Health and Aging Study and the 2004 Health and Retirement Study. Logistic regressions examine whether non-migrants or return migrants have different odds than immigrants of reporting a health outcome. Results The “salmon-bias” hypothesis holds for select health outcomes. However, non-migrants and return migrants have better health outcomes than immigrants on a variety of indicators. Discussion Overall, the results of this study do not support the salmon bias hypothesis; other explanations for the paradox could be explored. PMID:23264441

This study investigated the risk of cognitive and functional impairment in older Mexicans diagnosed with arthritis. Participants included 2,681 Mexicans, aged ≥60 years, enrolled in the Mexican Health and Aging Study cohort. Participants were categorized into arthritis and no arthritis exposure groups. Primary outcome included participants categorized into "cognitively impaired" or "cognitively normal" groups. Secondary outcomes included participants categorized into Normal, Functionally Impaired only, Cognitively Impaired only, or Dementia (both cognitively and functionally impaired) groups. Multivariable logistic and multinomial regression models were used to assess the relationships. Overall, 16% or 7% were diagnosed with cognitive impairment or dementia. Compared with older Mexicans without arthritis, those who were diagnosed with arthritis had significantly increased risk of functional impairment (adjusted odds ratio [OR] 1.82, 95% confidence interval [CI] = [1.45, 2.29]), but not of dementia. Arthritis is associated with increased risk of functional impairment, but not with dementia after 11 years in older Mexicans.

Background: Trichothiodistrophy (TTD) is a rare autosomal recessive condition that is characterized by a specific congenital hair shaft dysplasia caused by deficiency of sulfur associated with a wide spectrum of multisystem abnormalities. In this article, we study clinical, microscopic, and ultrastructural findings of 20 patients with TTD with the aim to add further insights regarding to this rare condition. Additionally, analyses of our results are compared with those extracted from the literature in order to enhance its comprehensibility. Materials and Methods: Twenty cases of TTD were included: 7 from Mexico and 14 from Spain. Clinical, microscopic, scanning electron microscopy (SEM) studies and X-ray microanalysis (XrMa) were carried out in all of them. Genetic studies were performed in all seven Mexican cases. Patients with xeroderma pigmentosum and xeroderma pigmentosum/TTD-complex were excluded. Results: Cuticular changes and longitudinal crests of the hair shaft were demonstrated. These crests were irregular, disorganized, following the hair longest axis. Hair shaft sulfur deficiency was disposed discontinuously and intermittently rather than uniformly. This severe decrease of sulfur contents was located close to the trichoschisis areas. Only five patients did not show related disturbances. Micro-dolichocephaly was observed in five cases and represented the most frequent facial dysmorphism found. It is also remarkable that all patients with urologic malformations also combined diverse neurologic disorders. Moreover, three Mexican sisters demonstrated the coexistence of scarce pubic vellus hair, developmental delay, onychodystrophy, and maxillar/mandibullar hypoplasia. Conclusions: TTD phenotype has greatly varied from very subtle forms to severe alterations such as neurologic abnormalities, blindness, lamellar ichthyosis and gonadal malformations. Herein, a multisystem study should be performed mandatorily in patients diagnosed with TTD. PMID:23180925

Canaries in a coalmine: Immigration and overweight among Mexican-origin children in the US and Mexico.

Van Hook, Jennifer; Baker, Elizabeth; Altman, Claire E; Frisco, Michelle L

2012-01-01

The prevalence of overweight is higher for Hispanic children of immigrants than children of natives. This does not fit the pattern of the epidemiological paradox, the widely supported finding that immigrants tend to be healthier than their U.S.-born peers, and it suggests that exposure to the U.S. increases immigrant children's risk of overweight. This study's primary contribution is to better assess how exposure to the U.S. environment affects childhood overweight among a homogamous ethnic group, Mexican-Americans. We do so by using an innovative binational study design to compare the weight of Mexican-American children of immigrants, Mexican-American children of natives, and Mexican children in Mexico with different propensities of having immigrant parents. Cross-sectional data are derived from a pooled sample of 9982 6-19 year old children living in either Mexico or the United States in the early 2000s. Mexican-resident children with a very high propensity to have immigrant parents have significantly lower percentile BMIs and lower odds of overweight than Mexican children with lower propensities of emigration and U.S.-resident Mexican-American children. This suggests that selection into immigration streams does not account for the high prevalence of overweight among children of Mexican immigrants. Rather, U.S. exposure significantly raises children of Mexican immigrants' risk of being overweight. Moreover, second generation children have the highest percentile BMIs and greatest odds of overweight of all comparison groups, including children of natives. This suggests that they experience risks above and beyond the effects of exposure to American society. Copyright © 2011 Elsevier Ltd. All rights reserved.

The purpose of this study is to see if contact with the dead is associated with lower death anxiety among older Mexican Americans. The data come from a nationwide survey of older Mexican Americans (N = 1,005). The study model specifies that: (a) older Mexican Americans who have experienced contact with the dead are more likely to see the connectedness that exists among all people; (b) seeing that all people are one promotes feelings of grateful to God; (c) gratitude toward God is, in turn, associated with lower death anxiety. The findings support each of these relationships. PMID:24563948

Unprotected sex is a critical issue in the Hispanic community, with the incidence of new Hispanic acquired immune deficiency syndrome (AIDS) cases three times that of non-Hispanic Whites. The researchers used focus groups to examine: (a) whether newly immigrated Mexican men and women in the Southeast United States discussed human immunodeficiency virus (HIV)/sexually transmitted disease (STD) prevention with each other, and (b) how condom use was discussed. For the women, communication was safe sex, and for the men, trust was safe sex. Both communication and trust were dependent on timing in the relationship. Participants could not discuss condoms in a new or established relationship because of issues of trust. This study highlights the complexity of HIV/STD prevention and suggests that trust and timing should be considered within the cultural context of condom introduction.

Human papillomavirus (HPV) is an epitheliotropic, double-stranded DNA virus, and its high-risk genotypes are associated with human cancer. HPV genome has been detected in lung carcinomas in certain places around the world, including Mexico; however, the prevalence of this is unclear. In this study, we examine the frequency of high-risk HPV 16/18 in lung cancer tissues from a Mexican population. 39 lung cancer specimens were analyzed by polymerase chain reaction (PCR) using HPV GP5+/GP6+ primers and then were genotyped using specific primers to HPV 16/18. Additionally, in situ hybridization (ISH) was performed using BIO-labeled oligonucleotide probes. Our results identified 15 positive cases (38.46%) for HPV 16 and 1 positive case (2.56%) for HPV 18 by PCR. ISH showed the presence of HPV DNA in 13 of 16 (81%) samples, in agreement with the PCR results. In this study, we detected HPV 16/18 gene sequences in lung cancer samples obtained from Mexican patients by PCR and ISH. We found the highest prevalence of HPV 16 infection in lung adenocarcinomas, suggesting that HPV infection may be associated with lung cancer. However, further studies are needed to elucidate the role of HPV in lung carcinogenesis. Copyright © 2013 S. Karger AG, Basel.

Racial Identity and Racial Treatment of Mexican Americans

How racial barriers play in the experiences of Mexican Americans has been hotly debated. Some consider Mexican Americans similar to European Americans of a century ago that arrived in the United States with modest backgrounds but were eventually able to participate fully in society. In contrast, others argue that Mexican Americans have been racialized throughout U.S. history and this limits their participation in society. The evidence of persistent educational disadvantages across generations and frequent reports of discrimination and stereotyping support the racialization argument. In this paper, we explore the ways in which race plays a role in the lives of Mexican Americans by examining how education, racial characteristics, social interactions, relate to racial outcomes. We use the Mexican American Study Project, a unique data set based on a 1965 survey of Mexican Americans in Los Angeles and San Antonio combined with surveys of the same respondents and their adult children in 2000, thereby creating a longitudinal and intergenerational data set. First, we found that darker Mexican Americans, therefore appearing more stereotypically Mexican, report more experiences of discrimination. Second, darker men report much more discrimination than lighter men and than women overall. Third, more educated Mexican Americans experience more stereotyping and discrimination than their less-educated counterparts, which is partly due to their greater contact with Whites. Lastly, having greater contact with Whites leads to experiencing more stereotyping and discrimination. Our results are indicative of the ways in which Mexican Americans are racialized in the United States. PMID:24307918

There is a void in the literature with regard to Hispanic parents' views about common interventions for children with behavior problems. The purpose of this study was to examine the treatment acceptability of child management techniques in a Mexican American sample. Parents' acculturation was also examined to determine if it would account for differences in treatment acceptability. Mexican American parents found response cost, a punishment-based technique, more acceptable than positive reinforcement-based techniques (e.g., differential attention). Results suggest that Mexican American parents' acculturation has little impact on acceptability of child management interventions. No association was found between mothers' acculturation and treatment acceptability. However, more acculturated Mexican American fathers viewed token economy as more acceptable than less acculturated fathers. Results are discussed in the context of clinical work and research with Mexican Americans.

Nineteenth century Mexican statures in the United States and their relationship with insolation and vitamin D.

The use of height data to measure living standards is now a well-established method in economics. However, there are still some populations, places and times for which the comparison across groups remains unclear. One example is 19th century Mexicans in the US. This study demonstrates that after comparing the statures of Mexicans born in Mexico and the US the primary source of the stature difference between the two groups was birth year, and the stature gap increased as the US economy developed while the Mexican economy stagnated. Moreover, the stature growth of Mexicans born in the US was related to vitamin D, and the Mexican relationship between stature and insolation was more like that of Europeans than Africans.

Older men are less likely than older women to receive depression treatment. Latino older men in particular have been found to have significantly lower rates of depression treatment than their white-non-Mexican (WNM) counterparts. Prior research has shown that men are less likely than women to express overt affect and/or report depression symptoms that may prompt primary care physicians' inquiry about depression. Previous studies have overlooked the idioms of distress common among older men. This study investigates: a) the range of idioms of distress that emerge in the narratives of depressed older men, and b) the use of these idioms among depressed WNM and Mexican-origin older men. The present report is based on qualitative data collected through the Men's Health and Aging Study (MeHAS), a mixed-method study of clinically depressed WNM and Mexican-origin older (65 and above) men recruited in primary care settings. Qualitative analysis of 77 interviews led to identification of idioms of distress and informed idiom categories. Study findings show that: a) both groups of men utilized a range of idioms of distress that met current DSM criteria for depression, b) both groups were also likely to utilize idioms that feel outside clinical depression criteria, and c) there were similarities as well as differences between WNM and Mexican-origin men. This study provides a larger vocabulary that clinicians might consider in recognizing depression and initiating depression care for older men from diverse ethnic backgrounds. This is important to improve depression care among older men in general and those of Mexican-origin in particular.

Mexican-origin families are a large and rapidly increasing subgroup of the U.S. population, but they remain underrepresented in family scholarship. This paper introduces a special section of four papers on Mexican-origin families designed to contribute to the advancement of research on how cultural, family, and gender socialization processes unfold across key developmental periods and life transitions in this cultural context. Two longitudinal studies of Mexican-origin families provided the data for these four papers: (a) The Juntos Project, an eight-year longitudinal study of mothers, fathers, and adolescent sibling pairs in 246 Mexican-origin families; and (b) The Supporting MAMI Project, a study following 204 adolescent mothers and their mother figures from the third trimester of pregnancy through their young children's 5th birthdays. In this introductory paper we highlight four themes, including (a) differential acculturation and reciprocal socialization, (b) interdependence in families, (c) the intersection of culture and gender, and (d) methodological issues, then offer suggestions for future research.

Mexican American women are disproportionately affected by overweight/obesity and the health complications accompanying them, but weight loss treatments are less successful in this ethnic group. High levels of familism, a value reflecting obligation to family that supersedes attention to oneself, interfere with weight loss for Mexican American women. This mixed methods study investigated overweight Mexican American women's beliefs about how familism, and Mexican American culture, might hinder weight loss success, and how treatments might be culturally adapted. Results suggest a need to support women in their commitment to family while also helping them make changes. Recommendations for culturally adapted treatments are made.

OBJECTIVES: This study examined the association between acculturation of Mexican-origin women and factors in low birthweight and preterm delivery. METHODS: Interviews were conducted with 911 Mexican-origin respondents in Los Angeles prenatal care clinics. Infant outcome data were retrieved from delivery records. RESULTS: Mexican-American women had generally more undesirable prenatal behaviors and risk factors than Mexican-immigrant women. Although higher acculturation was significantly associated with behavioral risk factors, there were no direct effects of acculturation on infant gestational age or birthweight. CONCLUSIONS: Future research needs to measure multiple factors to assess their effects on culture-specific protective factors. PMID:9224189

Meningococcal meningitis is reported as a rare condition in Mexico. There are no internationally published studies on bacterial causes of meningitis in the country based on active surveillance. This study focuses on finding the etiology of bacterial meningitis in children from nine Mexican Hospitals. From January 2010 to February 2013, we conducted a three years of active surveillance for meningitis in nine hospitals throughout Mexico. Active surveillance started at the emergency department for every suspected case, and microbiological studies confirmed/ruled out all potentially bacterial pathogens. We diagnosed based on routine cultures from blood and cerebrospinal fluid (not polymerase chain reaction or other molecular diagnostic tests), and both pneumococcal serotyping and meningococcal serogrouping by using standard methods. Neisseria meningitidis was the leading cause, although 75% of cases occurred in the northwest of the country in Tijuana on the US border. Serogroup C was predominant. Streptococcus pneumoniae followed Neisseria meningitides, but was uniformly distributed throughout the country. Serotype 19A was the most incident but before universal implementation of the 13-valent pneumococcal conjugate vaccine. Other bacteria were much less common, including Enterobacteriaceae and Streptococcus agalactiae (these two affecting mostly young infants). Meningococcal meningitis is endemic in Tijuana, Mexico, and vaccination should be seriously considered in that region. Continuous universal vaccination with the 13-valent pneumococcal conjugate vaccine should be nationally performed, and polymerase chain reaction should be included for bacterial detection in all cultures - negative but presumably bacterial meningitis cases.

To compare the socio-economic characteristics, clinical features and health-related quality of life in Hispanic SLE patients residing in Mexico and in the Southwest USA (Mexican and Texan, herein). Mexican and Texan SLE patients (fulfilling ACR criteria) participating in separate longitudinal outcome studies were evaluated. Texan patients were randomly chosen to match total disease duration with the Mexican patients. Cross-sectional data for the Mexican patients were obtained by a US-trained investigator who had previously participated in data collection for the cohort to which the Texan patients belonged. Socio-economic and -demographic characteristics, clinical characteristics, disease activity (with SLAM-Revised), damage accrual (with SLICC/ACR Damage Index) and self-reported function (with Short Form-36) were compared between the two groups. Seventy Mexican patients were matched with either one or two Texan patients (n = 94) for a total of 164 patients. Mexican patients were younger. In age-adjusted analyses, the Mexican patients were more educated, had better health-related quality of life and overall less systemic SLE manifestations. Mexican patients were exposed more frequently to AZA. Texan patients had more severe disease than the Mexican patients. In multivariable analyses, Texan Hispanic ethnicity was significantly associated with high disease activity, but significance was not reached for damage. The discrepant findings observed between these two Hispanic groups of SLE patients may reflect socio-economic or biological factors. Given the global phenomenon of immigration, rheumatologists should be aware of the overall course and outcome of immigrant SLE patients if undesirable outcomes are to be prevented.

2015-01-01

Compared with white children, the oral health of Latino children in the United States is much worse. One factor contributing to oral health is tooth brushing. Few studies have addressed the formation of the tooth brushing habit in children, and only one of them studied a Latino population. The purpose of this study is to explore the development of the tooth brushing habit in children of Mexican immigrant families and develop hypothesis based on its results. This is an exploratory qualitative study, with a case study design based on 20 in-depth interviews. Participants were Mexican immigrant mothers living in Pittsburgh and Philadelphia, PA. Participants had at least one child six-years-old or younger. Interviews were recorded, transcribed verbatim, and analyzed using qualitative analysis procedures. Four stages were identified in the tooth brushing learning process: initiation and entirely dependent tooth brushing, assisted tooth brushing, road to tooth brushing independence, and independent tooth brushing. Two factors influenced parents' teaching approaches: parents' perceptions of their child's achievement of physical, cognitive, and motor developmental milestones and parents' knowledge about oral hygiene. We identified four distinct stages and found evidence to hypothesize that transitions from one stage to the next are triggered not by the age of the child but by parents' knowledge about oral hygiene and their perceptions of their child's achievement of physical, cognitive, and motor developmental milestones. Future quantitative research studies should be conducted to test this hypothesis in larger groups of Latinos as well as other ethnic groups. © 2015 American Association of Public Health Dentistry.

AIM: To investigate features of Epstein-Barr virus (EBV)-associated gastric carcinoma (EBVaGC) among a Mexican population. METHODS: Cases of primary gastric adenocarcinoma were retrieved from the files of the Departments of Pathology at the Instituto Nacional de Cancerología and the Instituto Nacional de la Nutrición in Mexico City. The anatomic site of the gastric neoplasia was identified, and carcinomas were histologically classified as intestinal and diffuse types and subclassified as proposed by the Japanese Research Society for Gastric Cancer. EBV-encoded small non-polyadenylated RNA-1 (EBER-1) in situ hybridization was conducted to determine the presence of EBV in neoplastic cells. RESULTS: We studied 330 consecutive, non-selected, primary gastric carcinomas. Among these, there were 173 male and 157 female patients (male/female ratio 1.1/1). EBER-1 was detected in 24 (7.3%) cases (male/female ratio: 1.2/1). The mean age for the entire group was 58.1 years (range: 20-88 years), whereas the mean age for patients harboring EBER-1-positive gastric carcinomas was 65.3 years (range: 50-84 years). Age and histological type showed statistically significant differences, when EBER-1-positive and -negative gastric carcinomas were compared. EBER-1 was detected in hyperplastic- and dysplastic-gastric mucosa surrounding two EBER-1-negative carcinomas, respectively. CONCLUSION: Among Latin-American countries, Mexico has the lowest frequency of EBVaGC. Indeed, the Mexican population >50 years of age was selectively affected. Ethnic variations are responsible for the epidemiologic behavior of EBVaGC among the worldwide population. PMID:16273633

2015-01-01

Objectives To investigate the association between short-term changes in ambient pollution (particulate matter < 2.5μm in aerodynamic diameter (PM2.5) and ozone (O3)) and the risk of ischemic stroke among individuals living in a bi-ethnic community and whether this association is modified by ethnicity. Methods We identified incident ischemic stroke cases from the population-based Brain Attack Surveillance in Corpus Christi (BASIC) project between 2000 and 2012. Associations between PM2.5 (mean 24-hour) and O3 (maximal 8-hour) levels, measured on the same-day and lags of 1-3 days, and odds of ischemic stroke were assessed using a time-stratified case-crossover design and modeled using conditional logistic regression. We explored race/ethnicity (Mexican American versus non-Hispanic white) as a modifier by including interaction terms in the models. Results There were 2,948 ischemic strokes with median age 71 years (IQR: 59-80). We observed no overall associations between the air pollutants and odds of ischemic stroke at any lag. When stratified by ethnicity, higher O3 was consistently associated with greater odds of ischemic stroke for non-Hispanic whites, but not for Mexican Americans. Higher PM2.5 was generally associated with lower odds of ischemic stroke for non-Hispanic whites but modestly greater odds for Mexican Americans. Conclusion Ethnic differences in the associations between ischemic stroke and short-term exposures to O3 and PM2.5 were suggested indicating that further study in diverse populations may be warranted.

Mexican cleft surgeons provide multidisciplinary comprehensive cleft lip and palate care to children in Mexico. Many Mexican cleft surgeons have extensive experience with foreign, visiting surgeons. The purpose of this study was to characterize Mexican cleft surgeons' domestic and volunteer practice and to learn more about Mexican cleft surgeons' experience with visiting surgeons. A cross-sectional validated e-mail survey tool was sent to Mexican cleft surgeons through 2 Mexican plastic surgery societies and the Asociación Mexicana de Labio y Paladar Hendido y Anomalías Craneofaciales, the national cleft palate society that includes plastic and maxillofacial surgeons who specialize in cleft surgery. We utilized validated survey methodology, including neutral fact-based questions and repeated e-mails to survey nonresponders to maximize validity of statistical data; response rate was 30.6% (n = 81). Mexican cleft surgeons performed, on average, 37.7 primary palate repairs per year with an overall complication rate of 2.5%; 34.6% (n = 28) of respondents had direct experience with patients operated on by visiting surgeons; 53.6% of these respondents performed corrective surgery because of complications from visiting surgeons. Respondents rated 48% of the functional outcomes of visiting surgeons as "acceptable," whereas 43% rated aesthetic outcomes of visiting surgeons as "poor"; 73.3% of respondents were never paid for the corrective surgeries they performed. Thirty-three percent of Mexican cleft surgeons believe that there is a role for educational collaboration with visiting surgeons. Mexican cleft surgeons have a high volume of primary cleft palate repairs in their domestic practice with good outcomes. Visiting surgeons may play an important role in Mexican cleft care through educational collaborations that complement the strengths of Mexican cleft surgeons.

SES Gradients Among Mexicans in the United States and in Mexico: A New Twist to the Hispanic Paradox?

PubMed

Beltrán-Sánchez, Hiram; Palloni, Alberto; Riosmena, Fernando; Wong, Rebeca

2016-10-01

Recent empirical findings have suggested the existence of a twist in the Hispanic paradox, in which Mexican and other Hispanic foreign-born migrants living in the United States experience shallower socioeconomic status (SES) health disparities than those in the U.S. In this article, we seek to replicate this finding and test conjectures that could explain this new observed phenomenon using objective indicators of adult health by educational attainment in several groups: (1) Mexican-born individuals living in Mexico and in the United States, (2) U.S.-born Mexican Americans, and (3) non-Hispanic American whites. Our analytical strategy improves upon previous research on three fronts. First, we derive four hypotheses from a general framework that has also been used to explain the standard Hispanic paradox. Second, we study biomarkers rather than self-reported health and related conditions. Third, we use a binational data platform that includes both Mexicans living in Mexico (Mexican National Health and Nutrition Survey 2006) and Mexican migrants to the United States (NHANES 1999-2010). We find steep education gradients among Mexicans living in Mexico's urban areas in five of six biomarkers of metabolic syndrome (MetS) and in the overall MetS score. Mexican migrants living in the United States experience similar patterns to Mexicans living in Mexico in glucose and obesity biomarkers. These results are inconsistent with previous findings, suggesting that Mexican migrants in the United States experience significantly attenuated health gradients relative to the non-Hispanic white U.S. Our empirical evidence also contradicts the idea that SES-health gradients in Mexico are shallower than those in the United States and could be invoked to explain shallower gradients among Mexicans living in the United States.

To know the differences in food availability according to food insecurity level among the Mexican households. We analyzed the database of the National Survey of Household's Incomes and Expenditures (n=27 445 households). Households were classified according to the Latin American and Caribbean Inventory of Food Security. The availability of each food group was estimated as grams per day per equivalent adult. 50.0% of Mexican households experienced some degree of food insecurity. Among households with food insecurity there was high availability of corn, wheat, egg, and sugars; but there was low availability of fresh fruits and vegetables, lean meat, poultry, seafood, milk, cheeses, and sweetened beverages. Although in households with food insecurity there is lower availability of most food groups (both with high nutrient density and with high energy density); they have higher availability of cheap foods, which in some cases are only source of energy but do not provide nutrients.

Gender differences in immigrant health: the case of Mexican and Middle Eastern immigrants.

PubMed

Read, Jen'nan Ghazal; Reynolds, Megan M

2012-03-01

This article draws on theories of gender inequality and immigrant health to hypothesize differences among the largest immigrant population, Mexicans, and a lesser known population of Middle Easterners. Using data from the 2000-2007 National Health Interview Surveys, we compare health outcomes among immigrants to those among U.S.-born whites and assess gender differences within each group. We find an immigrant story and a gender story. Mexican and Middle Eastern immigrants are healthier than U.S.-born whites, and men report better health than women regardless of nativity or ethnicity. We identify utilization of health care as a primary mechanism that contributes to both patterns. Immigrants are less likely than U.S.-born whites to interact with the health care system, and women are more likely to do so than men. Thus, immigrant and gender health disparities may partly reflect knowledge of health status rather than actual health.

Perceived ethnic discrimination is central to the experiences of Latino young adults, yet we know little about the ways in which and the conditions under which ethnic discrimination relates to Latino young adults' sleep patterns. Using a sample of 246 Mexican-origin young adults (M age  = 21.11, SD = 1.54; 50 % female), the current study investigated the longitudinal links between perceived ethnic discrimination and both sleep duration and night-to-night variability in duration, while also examining the moderating roles of Anglo and Mexican orientations in the associations. The results revealed that perceived discrimination predicted greater sleep variability, and this link was not moderated by cultural orientations. The relation between perceived discrimination and hours of sleep, however, was moderated by Anglo and Mexican orientations. Individuals with high Anglo and Mexican orientations (bicultural) and those with only high Mexican orientations (enculturated), showed no association between discrimination and hours of sleep. Individuals with low Anglo and Mexican orientations (marginalized) displayed a positive association, whereas those with high Anglo and low Mexican orientations (acculturated) displayed a negative association. The results suggest that discrimination has long term effects on sleep variability of Mexican-origin young adults, regardless of cultural orientations; however, for sleep duration, bicultural and enculturated orientations are protective.

The current project sought to develop the Mexican Intercultural Competence Scale (MICS), which assesses group-specific skills and attributes that facilitate effective cultural interactions, among adults of Mexican descent. Study 1 involved an Exploratory Factor Analysis (N = 184) that identified five factors including Ambition/Perseverance, Networking, the Traditional Latino Culture, Family Relationships, and Communication. In Study 2, a Confirmatory Factor Analysis provided evidence for the 5-factor model for adults of Mexican origin living in the Midwest (N = 341) region of the U.S. The general findings are discussed in terms of a competence-based formulation of cultural adaptation and include theoretical and clinical implications.

2017-01-01

Although the association between acculturation and substance use among Latino groups is important, it is often understudied, especially within specific Latino groups living in geographically distinct communities, such as the Mexican American population in South Texas. The researchers of this study aimed to better understand the effect of acculturation on substance use and alcohol dependence in a Mexican American college student population. This survey study investigated the correlation between acculturation and substance use and dependence by using the Vancouver Index of Acculturation (VIA), items related to substance use (nicotine, marijuana, and cocaine) in a Mexican American college student sample (N = 1,494), and the Short Alcohol Dependence Data Questionnaire (SADD; N = 715). The study was conducted in the Texas-Mexico border region. The results suggest that higher levels of acculturation do not predict increased drug use or alcohol dependence in the Mexican American college students. However, acculturation was found to be associated with lower use of cocaine and marijuana. The discussion examines commonalities and differences in drug use and dependence. Specifically, acculturation seems to have an inverse relationship to substance use and may serve as a protective factor to licit and illicit drug use among Mexican American college students.

This study investigated the cross-cultural and intra cultural diversity of mothers' beliefs and values regarding child rearing, education, and the causes of language impairment. Thirty Mexican-American and 30 Anglo-American mothers of children with language impairments completed 2 questionnaires, and 10 randomly selected mothers from each group participated in an interview. In addition, the Mexican-American mothers completed an acculturation rating scale. Results indicated that Mexican-American mothers held more strongly traditional, authoritarian, and conforming educational and child rearing beliefs and values than Anglo-American mothers. Mexican-American mothers cited extrinsic attributes as the cause of their children's language impairment, whereas Anglo-American mothers cited intrinsic attributes. Mexican-American mothers exhibited differences in their beliefs that were related to their level of acculturation to the mainstream culture.

Diagnosis-related groups (DRGs) are widely used in Europe. They allow performing comparisons in hospitals and incurrent hospital payment systems, defining the payment categories. We undertook this study to classify children who underwent appendectomy according to DRGs. Cross-sectional study. Comorbidities, length of hospitalization, histopathologic classification, and DRG classifications were analyzed. We included 313 patients, 62% males, with an average age of 8 ± 3 years; 91% were referred by another hospital and 67% were treated at night. Average length of hospitalization was 4 ± 3 days. There were comorbidities in 8% and surgical complications in 11%. According to histopathology, appendicitis was edematous (11%), suppurative (36%), gangrenous (22%), perforated (29%), and abscessed (2%). At discharge, 97% of the patients were healthy. Total cost for DRG 343 was $10,470,173.00 (Mexican pesos), DRG 342 was $1,227,592.00 and DRG 340 was $511,521.00. The global amount was $12,209,286.00 (Mexican pesos). The unitary cost for treatment of appendectomy for DRG 343 was $37,935.00, for DRG 342 was $49,103.00 and for DRG 340 was $42,626.00 (Mexican pesos). Because 88% of the cases of appendicitis were uncomplicated, this amount of money could be spent to treat these patients in a second-level hospital, using reimbursement 343 without generating additional expenses.

Moving Beyond Salmon Bias: Mexican Return Migration and Health Selection

Diaz, Christina J.; Koning, Stephanie M.; Martinez-Donate, Ana P.

2017-01-01

Despite having lower levels of education and limited access to health care services, Mexican immigrants report better health outcomes than U.S.-born individuals. Research suggests that the Mexican health advantage may be partially attributable to selective return migration among less healthy migrants—often referred to as “salmon bias.” Our study takes advantage of a rare opportunity to observe the health status of Mexican-origin males as they cross the Mexican border. To assess whether unhealthy migrants are disproportionately represented among those who return, we use data from two California-based studies: the California Health Interview Survey; and the Migrante Study, a survey that samples Mexican migrants entering and leaving the United States through Tijuana. We pool these data sources to look for evidence of health-related return migration. Results provide mixed support for salmon bias. Although migrants who report health limitations and frequent stress are more likely to return, we find little evidence that chronic conditions and self-reported health are associated with higher probabilities of return. Results also provide some indication that limited health care access increases the likelihood of return among the least healthy. This study provides new theoretical considerations of return migration and further elucidates the relationship between health and migration decisions. PMID:27848222

Factors Contributing to 50-ft Walking Speed and Observed Ethnic Differences in Older Community-Dwelling Mexican Americans and European Americans

Hazuda, Helen P.

2015-01-01

Background Mexican Americans comprise the most rapidly growing segment of the older US population and are reported to have poorer functional health than European Americans, but few studies have examined factors contributing to ethnic differences in walking speed between Mexican Americans and European Americans. Objective The purpose of this study was to examine factors that contribute to walking speed and observed ethnic differences in walking speed in older Mexican Americans and European Americans using the disablement process model (DPM) as a guide. Design This was an observational, cross-sectional study. Methods Participants were 703 Mexican American and European American older adults (aged 65 years and older) who completed the baseline examination of the San Antonio Longitudinal Study of Aging (SALSA). Hierarchical regression models were performed to identify the contribution of contextual, lifestyle/anthropometric, disease, and impairment variables to walking speed and to ethnic differences in walking speed. Results The ethic difference in unadjusted mean walking speed (Mexican Americans=1.17 m/s, European Americans=1.29 m/s) was fully explained by adjustment for contextual (ie, age, sex, education, income) and lifestyle/anthropometric (ie, body mass index, height, physical activity) variables; adjusted mean walking speed in both ethnic groups was 1.23 m/s. Contextual variables explained 20.3% of the variance in walking speed, and lifestyle/anthropometric variables explained an additional 8.4%. Diseases (ie, diabetes, stroke, chronic obstructive pulmonary disease) explained an additional 1.9% of the variance in walking speed; impairments (ie, FEV1, upper leg pain, and lower extremity strength and range of motion) contributed an additional 5.5%. Thus, both nonmodifiable (ie, contextual, height) and modifiable (ie, impairments, body mass index, physical activity) factors contributed to walking speed in older Mexican Americans and European Americans. Limitations The study was conducted in a single geographic area and included only Mexican American Hispanic individuals. Conclusions Walking speed in older Mexican Americans and European Americans is influenced by modifiable and nonmodifiable factors, underscoring the importance of the DPM framework, which incorporates both factors into the physical therapist patient/client management process.

From the end of a revolution to the beginning of an evolution: An interpretive investigation on the Mexican oil culture

NASA Astrophysics Data System (ADS)

Marquez-Perez, Pedro Gabriel

2001-07-01

This dissertation is an interpretative investigation on the Mexican petroleum industry. It studies the social arrangement that allowed the development of Mexico's most important State-Owned Enterprise Petroleos Mexicanos and the current pressures to transform it. The need to modify its operations in Mexico is an issue of enormous significance for the current reforms undertaken by the Neo-liberal project initiated during the mid 1980's. It represents the abandonment of the development strategy that characterized the "Regime of the Revolution" and the establishment of a market-oriented economy in line with the development strategy selected by the President Fox for the period 2000--2006. Through an approximation of Habermas' ideal 'Public Sphere' this dissertation reveals relevant information about PEMEX's historical and present contexts, the basic elements that make up the Mexican petroleum culture, its major interest groups, their mutual perspectives and understandings, their interpretation of the present situation and their opinion as to the way PEMEX should be modified. The investigation into the ideas, beliefs and customs that justified PEMEX's hegemony over Mexico's petroleum resources followed the conceptual model provided by the Critical Theory Paradigm and an adaptation of a methodological approach previously employed for qualitative Critical Theory research. Throughout an ethnographic analysis of twenty-six representatives of PEMEX's major interest groups through in-depth, semi-structured interviews based on a combination of an interpretative research design and a case-study research method, the beliefs, ideals, mutual perceptions and future plans of these stakeholders were identified. This study advances the understanding of the symbols, beliefs and ideas that have framed Mexican petroleum culture, as well as describes how these beliefs and ideas have changed over time. Through an 'ethnography of rhetoric,' this project facilitated the absorption and comprehension of their world, ideologies and expectations. Therefore, it contains the analysis of a whole rhetoric that legitimated an enduring and incredibly powerful political regime with an ideology that justified 'a way of life.' The study concludes with a call to exercise self-reflection, get rid of the hundreds of 'False Consciousnesses' that modify Mexican behaviour every day, and endeavour to enter the wonderful experience of intellectual emancipation.

Crisis, neoliberal health policy, and political processes in Mexico.

PubMed

Laurell, A C

1991-01-01

The Mexican case represents an orthodox neoliberal health policy in the context of the structural adjustment adopted by the Mexican government in 1983. The social costs of this strategy are very high, including an increase in unemployment, wage depression, regressive redistribution of wealth, and profound changes in social policies. These transformations are reflected in the health sector, where the four main axes of neoliberal policy--expenditure restrictions, targeting, decentralization, and privatization--have been implemented. This represents a change in social policy from a model based on citizens' social rights and the state's obligation to guarantee them, to a model characterized by selective public charity. This strategy has been imposed on society as a result of the Mexican corporative political regime based on a state party system. Since 1985, however, there has been a growing process of independent organization of civil society. This led in the presidential elections of 1988 to the defeat of the candidate of the governing party by the candidate of a popular-democratic opposition front. Although the government party imposed its candidate through electoral fraud, social mobilization against neoliberal policies continues in the midst of an important political crisis that can only be resolved by profound democratization of Mexican society.

Treviño, R P; Treviño, F M; Medina, R; Ramirez, G; Ramirez, R R

1996-05-01

This study describes the rates of health care access among Mexican Americans with different health insurance coverage. An interview questionnaire was used to collect information regarding sociodemographics, perceived health status, health insurance coverage, and sources of health care from a random sample of 501 Mexican Americans from San Antonio, Texas. Health care access was determined more by having health insurance coverage than by health care needs. Poor Mexican Americans with health insurance had higher health care access rates than did poor Mexican Americans without health insurance. Health care access may improve health care outcomes, but more comprehensive community-based campaigns to promote health and better use of health services in underprivileged populations should be developed.

This study analyzes risk behaviors and attitudes related to HIV-AIDS transmission between young people from two Hispanic/Latino culture and origin (Mexico and Spain). For this purpose, 840 participants filled out the AIDS Prevention Questionnaire (Ballester et al., El "Cuestionario de Prevención del Sida (CPS)": Análisis de la fiabilidad y validez. Sociedad Española Interdisciplinaria del Sida, San Sebastián, 2007). From the Theory of reasoned action, our results revealed differences between the risk behaviour profiles of young people depending on their origin or gender, in terms of attitudes and behaviours. For example, Mexican participants have exhibited more levels of perceived risk or severity of HIV while for Spaniards, the fear of HIV was higher. Regarding the perception of condom use, loss of pleasure seems to be an important barrier for both groups of Mexican and Spanish young although others, such as lack of information would be reported only for Mexican women. Regarding self-efficacy, there are no significant differences in general but, in specific cases, we found them: Spanish participants seem to be more comfortable with putting on a condom while Mexican participants are more confident when it comes to buying it. However, these Spanish young people have reported more behavioural intention and present condom use in all sexual practices. In general, predictors of condom use are different depending on gender and origin. Thus, in order to develop effective strategies in AIDS prevention, cultural differences for HIV transmission should be considered even inside the group of Hispanic/Latino young people.

Does Selective Migration Explain the Hispanic Paradox?: A Comparative Analysis of Mexicans in the U.S. and Mexico

PubMed Central

Bostean, Georgiana

2014-01-01

Latino immigrants, particularly Mexican, have some health advantages over U.S.-born Mexicans and Whites. Because of their lower socioeconomic status, this phenomenon has been called the epidemiologic “Hispanic Paradox.” While cultural theories have dominated explanations for the Paradox, the role of selective migration has been inadequately addressed. This study is among the few to combine Mexican and U.S. data to examine health selectivity in activity limitation, self-rated health, and chronic conditions among Mexican immigrants, ages 18 and over. Drawing on theories of selective migration, this study tested the “healthy migrant” and “salmon-bias” hypotheses by comparing the health of Mexican immigrants in the U.S. to non-migrants in Mexico, and to return migrants in Mexico. Results suggest that there are both healthy migrant and salmon-bias effects in activity limitation, but not other health aspects. In fact, consistent with prior research, immigrants are negatively selected on self-rated health. Future research should consider the complexities of migrants’ health profiles and examine selection mechanisms alongside other factors such as acculturation. PMID:22618355

This study is among the few to combine Mexican and U.S. data to examine health selectivity in activity limitation, self-rated health, and chronic conditions among Mexican immigrants, ages 18 and over. Drawing on theories of selective migration, this study tested the "healthy migrant" and "salmon-bias" hypotheses by comparing the health of Mexican immigrants in the U.S. to non-migrants in Mexico, and to return migrants in Mexico. Results suggest that there are both healthy migrant and salmon-bias effects in activity limitation, but not other health aspects. In fact, consistent with prior research, immigrants are negatively selected on self-rated health. Future research should consider the complexities of migrants' health profiles and examine selection mechanisms alongside other factors such as acculturation.

Strong Selection at MHC in Mexicans since Admixture

Mexicans are a recent admixture of Amerindians, Europeans, and Africans. We performed local ancestry analysis of Mexican samples from two genome-wide association studies obtained from dbGaP, and discovered that at the MHC region Mexicans have excessive African ancestral alleles compared to the rest of the genome, which is the hallmark of recent selection for admixed samples. The estimated selection coefficients are 0.05 and 0.07 for two datasets, which put our finding among the strongest known selections observed in humans, namely, lactase selection in northern Europeans and sickle-cell trait in Africans. Using inaccurate Amerindian training samples was a major concern for the credibility of previously reported selection signals in Latinos. Taking advantage of the flexibility of our statistical model, we devised a model fitting technique that can learn Amerindian ancestral haplotype from the admixed samples, which allows us to infer local ancestries for Mexicans using only European and African training samples. The strong selection signal at the MHC remains without Amerindian training samples. Finally, we note that medical history studies suggest such a strong selection at MHC is plausible in Mexicans.

Salinas, Jennifer J; Peek, M Kristen

The purpose of this study is to examine the relationship between labor force participation and gender differences in the prevalence of arthritis, diabetes, and hypertension. The Mexican Health and Aging Survey (MHAS) data is nationally representative sample of older Mexicans 50 years and older. Binomial logistic regression models were performed to examine differences between older Mexican men and women in the prevalence of arthritis, diabetes, and hypertension. Interaction effects were also estimated between gender and occupation, length of time in the labor force, and pension eligibility. Older Mexican women have a significantly greater risk of having arthritis, diabetes, and hypertension. Findings from this study suggest that within the same occupational classification, women suffer from the damaging effects on health to a greater extent than men. Interaction effects show that women who work in services or in client's home are particularly susceptible to arthritis. Moreover, women who work in sales were at a significantly greater risk of hypertension than men. Older Mexican women are at greater risk of chronic disease and part of their vulnerability is a result of the type of work that they do.

Objectives. We investigated whether Mexican immigration to the United States exerts transnational effects on substance use in Mexico and the United States. Methods. We performed a cross-sectional survey of 2336 Mexican Americans and 2460 Mexicans in 3 Texas border metropolitan areas and their sister cities in Mexico (the US–Mexico Study on Alcohol and Related Conditions, 2011–2013). We collected prevalence and risk factors for alcohol and drug use; Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, alcohol-use disorders; and 2 symptoms (hazardous use and quit or control) of drug use disorder across a continuum of migration experiences in the Mexican and Mexican American populations. Results. Compared with Mexicans with no migrant experience, the adjusted odds ratios for this continuum of migration experiences ranged from 1.10 to 8.85 for 12-month drug use, 1.09 to 5.07 for 12-month alcohol use disorder, and 1.13 to 9.95 for 12-month drug-use disorder. Odds ratios increased with longer exposure to US society. These findings are consistent with those of 3 previous studies. Conclusions. People of Mexican origin have increased prevalence of substance use and disorders with cumulative exposure to US society. PMID:26562124

Cystic fibrosis, the most common autosomal recessive disorder, is caused by defects in the CF transmembrane conductance regulator gene (CFTR) that encodes a chloride channel. To date, over 1,800 mutations have been described related to the causative gene of CF, showing a variable frequency among populations. In a previous extensive analysis of the CFTR locus in 97 Mexican patients, 34 different mutations (75% of CF alleles) were found using several strategies for mutation screening; however, 63% had at least an uncharacterized allele. Despite the combined technologies used, there are still a great number of unknown mutations in the Mexican population. Screening of the CFTR gene to provide additional evidence of the mutational wide spectrum responsible for CF in Mexican patients. In this study, the number of unrelated CF patients was increased to 230, 133 new cases and the 97 previously reported to include 63% with at least an uncharacterized allele. Additional tools were used to improve the detection rate of CF mutations, such as a commercial kit for 36 mutations plus a single chain conformational polymorphism method and DNA sequencing. By using a combination of these strategies we characterized 77.7% of all the CF alleles, resulting in a total of 46 different mutations detected, including the identification of 12 additional mutations (p.R334W, p.A455E, c.3120+1G > A, c.3272-26A > G, c.711+1G > T, p.Q552X, p.W1282X, c.IVS8-5T, p.R1162X and p.R347P, p.D1152H and p.T1036N). Although these 12 mutations have been reported in other populations, they have not yet been reported in Mexican patients. This report shows that Mexico has one of the widest spectra of CFTR mutations worldwide. The knowledge of the ethnic and geographic distribution of CFTR mutations in this population will allow the development of more effective methods for diagnosis and treatment.

A number of studies have investigated use of extreme (ERS) and acquiescent (ARS) response styles across cultural groups. However, due to within-group heterogeneity, it is important to also examine use of response styles, acculturation, and endorsement of cultural variables at the individual level. This study explores relationships between acculturation, six Mexican cultural factors, ERS, and ARS among a sample of 288 Mexican American telephone survey respondents. Three aspects of acculturation were assessed: Spanish use, the importance of preserving Mexican culture, and interaction with Mexican Americans versus Anglos. These variables were hypothesized to positively associate with ERS and ARS. Participants with higher Spanish use did utilize more ERS and ARS; however, value for preserving Mexican culture and interaction with Mexican Americans were not associated with response style use. In analyses of cultural factors, endorsement of familismo and simpatia were related to more frequent ERS and ARS, machismo was associated with lower ERS among men, and la mujer was related to higher ERS among women. Caballerismo was marginally associated with utilization of ERS among men. No association was found between la mujer abnegada and ERS among women. Relationships between male gender roles and ARS were nonsignificant. Relationships between female gender roles and ARS were mixed but trended in the positive direction. Overall, these findings suggest that Mexican American respondents vary in their use of response styles by acculturation and cultural factors. This usage may be specifically influenced by participants' valuing of and engagement with constructs directly associated with social behavior.

Mexican American intergenerational caregiving model.

PubMed

Escandón, Socorro

2006-08-01

This study employed grounded theory to formulate a conceptual model of intergenerational caregiving among Mexican American families. The sample consisted of 10 Mexican American caregivers of various generations older than 21 who provided at least one intermittent service (without pay at least once a month) to an elder, related through consanguinal or acquired kinship ties. The inductively generated theory of role acceptance is composed of four phases: (a) introduction--early caregiving experiences, (b) role reconciliation, (c) role imprint, and (d) providing or projecting care. This model can be used to study varied generations of Mexican American caregivers. It also provides a framework for comparison with other groups of caregivers. The results can help in designing nursing interventions to support caregivers based on understanding the issues, to create and design systems that address the varying and ever-changing needs of informal caregivers, and to assist in the formulation of policy that supports Mexican American caregivers.

Objective. To compare the socio-economic characteristics, clinical features and health-related quality of life in Hispanic SLE patients residing in Mexico and in the Southwest USA (Mexican and Texan, herein). Methods. Mexican and Texan SLE patients (fulfilling ACR criteria) participating in separate longitudinal outcome studies were evaluated. Texan patients were randomly chosen to match total disease duration with the Mexican patients. Cross-sectional data for the Mexican patients were obtained by a US-trained investigator who had previously participated in data collection for the cohort to which the Texan patients belonged. Socio-economic and -demographic characteristics, clinical characteristics, disease activity (with SLAM-Revised), damage accrual (with SLICC/ACR Damage Index) and self-reported function (with Short Form-36) were compared between the two groups. Results. Seventy Mexican patients were matched with either one or two Texan patients (n = 94) for a total of 164 patients. Mexican patients were younger. In age-adjusted analyses, the Mexican patients were more educated, had better health-related quality of life and overall less systemic SLE manifestations. Mexican patients were exposed more frequently to AZA. Conclusions. Texan patients had more severe disease than the Mexican patients. In multivariable analyses, Texan Hispanic ethnicity was significantly associated with high disease activity, but significance was not reached for damage. The discrepant findings observed between these two Hispanic groups of SLE patients may reflect socio-economic or biological factors. Given the global phenomenon of immigration, rheumatologists should be aware of the overall course and outcome of immigrant SLE patients if undesirable outcomes are to be prevented. PMID:19717548

2014-06-01

Low maternal intake of dietary choline and betaine (a choline derivative) has recently been investigated as a possible risk factor for neural tube defects (NTDs). This case-control study examined the NTD risk associated with choline and betaine in 409 Mexican-American women who gave birth during 1995 to 2000 in the 14-county border region of Texas. Using data from the food frequency questionnaire and the lowest quartiles of intake as the reference categories, a protective association was suggested between higher intakes of choline and betaine and NTD risk although the 95% confidence intervals for all risk estimates included 1.0. For choline intake in the second, third, and fourth quartiles, adjusted odds ratios were 1.2, 0.80, and 0.89, respectively. Betaine appeared more protective with odds ratios of 0.62, 0.73, and 0.61, respectively, for the second, third, and fourth quartiles of intake. Study findings suggest that dietary betaine may help to prevent NTDs. © 2014 Wiley Periodicals, Inc.

Rodríguez-Fuentes, G; Gold-Bouchot, G

2000-01-01

Cholinesterase inhibition is considered a specific biomarker of exposure and effect for organophosphorous pesticides. Its use for monitoring has been hindered, particularly in tropical countries where organophosphates are widely used for malaria and dengue control, because of the frequent lack of suitable controls. An in vitro technique is proposed as a biochemical method for monitoring pollutant mixtures in sediment toxicity tests. Brain homogenate from the fish Oreochromis niloticus is used as the enzyme source. Optimum incubation time, extraction solvent and effect of crude oil on acetylcholinesterase (AChE) are reported. The method described was used in sediments from two Mexican lagoons, located in an oil extraction area where pesticides are used in agriculture and vector control campaigns. AChE inhibitions from 3 to 21% were found in these lagoons, even in the presence of high concentrations of petroleum.

Rheumatoid arthritis and Swine influenza vaccine: a case report.

PubMed

Basra, Gurjot; Jajoria, Praveen; Gonzalez, Emilio

2012-01-01

Rheumatoid arthritis (RA) is the most common chronic inflammatory joint disease. Multiple scientific articles have documented that vaccinations for influenza, MMR, and HBV, to name a few, could be triggers of RA in genetically predisposed individuals. However, there is limited data regarding the association of swine flu vaccine (H1N1) and RA. We report the case of a Mexican American female who developed RA right after vaccination with H1N1 vaccine. Genetically, RA has consistently been associated with an epitope in the third hypervariable region of the HLA-DR β chains, known as the "shared epitope", which is found primarily in DR4 and DR1 regions. The presence of HLA-DRB1 alleles is associated with susceptibility to RA in Mexican Americans. Hence, certain individuals with the presence of the "shared epitope" may develop RA following specific vaccinations. To our knowledge, this is the first reported case of RA following vaccination with the swine flu vaccine.

What can we learn from the study of Mexican-origin families in the United States?

Mexican-origin families are a large and rapidly increasing subgroup of the U.S. population, but they remain underrepresented in family scholarship. This paper introduces a special section of four papers on Mexican-origin families designed to contribute to the advancement of research on how cultural, family, and gender socialization processes unfold across key developmental periods and life transitions in this cultural context. Two longitudinal studies of Mexican-origin families provided the data for these four papers: (a) The Juntos Project, an 8-year longitudinal study of mothers, fathers, and adolescent sibling pairs in 246 Mexican-origin families; and (b) The Supporting MAMI Project, a study following 204 adolescent mothers and their mother figures from the third trimester of pregnancy through their young children's 5th birthdays. In this introductory paper, we highlight four themes, including (a) differential acculturation and reciprocal socialization, (b) interdependence in families, (c) the intersection of culture and gender, and (d) methodological issues. We end with suggestions for future research. © 2015 Family Process Institute.

Benthic amphipods (Amphipoda: Gammaridea and Corophiidea) from the Mexican southeast sector of the Gulf of Mexico: checklist, new records and zoogeographic comments.

2013-01-01

The southeast region of the Gulf of Mexico is considered to be biologically important, because it is a connection and transition zone between the Caribbean and the Gulf of Mexico, harboring great marine biodiversity. Nevertheless, benthic amphipods have been poorly studied in the Mexican southeast sector of the Gulf of Mexico with few studies listing species. The aim of this study is to provide an update checklist of species for the Mexican southeast sector (based on literature review and records from the present study) as well as a brief zoogeographical analysis for the Gulf of Mexico amphipod fauna, putting them in context with the fauna on the tropical western Atlantic. Fifty-five species were listed for the Mexican southeast sector; 36 of them showed a geographical extension to the Yucatan continental shelf representing 23 new records for the Mexican southeast sector, nine for the southeast region and four for the Gulf of Mexico. Based on the zoogeographical analysis, there is support of the application of Carolinian and Caribbean zoogeographic provinces to amphipods in the Gulf of Mexico.

SES Gradients Among Mexicans in the United States and in Mexico: A New Twist to the Hispanic Paradox?

PubMed Central

Palloni, Alberto; Riosmena, Fernando; Wong, Rebeca

2016-01-01

Recent empirical findings have suggested the existence of a twist in the Hispanic paradox, in which Mexican and other Hispanic foreign-born migrants living in the United States experience shallower socioeconomic status (SES) health disparities than those in the U.S. population. In this article, we seek to replicate this finding and test conjectures that could explain this new observed phenomenon using objective indicators of adult health by educational attainment in several groups: (1) Mexicanborn individuals living in Mexico and in the United States, (2) U.S.-born Mexican Americans, and (3) non-Hispanic American whites. Our analytical strategy improves upon previous research on three fronts. First, we derive four hypotheses from a general framework that has also been used to explain the standard Hispanic paradox. Second, we study biomarkers rather than self-reported health and related conditions. Third, we use a binational data platform that includes both Mexicans living in Mexico (Mexican National Health and Nutrition Survey 2006) and Mexican migrants to the United States (NHANES 1999–2010). We find steep education gradients among Mexicans living in Mexico’s urban areas in five of six biomarkers of metabolic syndrome (MetS) and in the overall MetS score. Mexican migrants living in the United States experience similar patterns to Mexicans living in Mexico in glucose and obesity biomarkers. These results are inconsistent with previous findings, suggesting that Mexican migrants in the United States experience significantly attenuated health gradients relative to the non-Hispanic white U.S. population. Our empirical evidence also contradicts the idea that SES-health gradients in Mexico are shallower than those in the United States and could be invoked to explain shallower gradients among Mexicans living in the United States.

Research on the prevalence and correlates of dating violence in Mexican teens is challenged by the lack of culturally and linguistically appropriate assessment tools. This study modified, translated, and back-translated the Conflict in Adolescent Dating Relationships Inventory (CADRI; Wolfe et al., 2001) and the Attitudes Towards Dating Violence Scales (Price, Byers, & the Dating Violence Research Team, 1999) for Mexican adolescents. Analyses on 307 adolescents (15-18 years old) from Monterrey and Mexicali, Mexico, revealed that most of the translated CADRI subscales and Attitudes Towards Dating Violence Scales had acceptable internal consistency and test-retest reliability coefficients. The study offers some evidence that the measures may be useful in assessing dating violence in Mexican teens.

Familism, machismo and child rearing practices among Mexican Americans.

PubMed

Tamez, E G

Mexican Americans form the 2nd largest minority group in the US. Fertility is 50% higher than in any other ethnic group. Income levels are inordinately low. In 1970, 42% of Mexican Americans were indigent, making approxiamtely 4200 annually. The Mexican American poor can be categorized into newly arrived aliens or 2nd or 3rd generation American citizens. In the 1st instance, the couple is young and English is not spoken. 2nd or 3rd generation Mexican Americans speak English. The persistent socioeconomic status of the Mexican American relates directly to the level of education. 52% of all Mexican Americans do not finish high school. Paz and Remos described the Mexican in terms of Adler's inferiority model. Murillo stated that to an individual, the family--whether nuclear or extended--is the center of life. The inherent responsibility is that the individual behave properly lest the family be disgraced. The family provides emotional and material security. Familism was seen as a deterrant to utilization of health care services, although some studies claim opposing views. Familism and occupational stability related positively to seeking medical care when ill. Hayden believed that supreme male dominance, individualism, pride, wife beating, aversion to contraceptives, and other characteristics were attributable to machismo. A predominant pattern in Mexican American culture is that of elders' ordering young men and women to establish obedience and male dominance. The husband represents authority and the wife-mother maintains a role of complete devotion to her husband and children. Role differentiation is taught implicitly and explicitly from infancy. Studies on the psychological differences between the sexes indicated that females were oppressed and had lower self esteem than males. 18-24 year old Mexican Americans are becoming less insistent upon strict separation of sex roles and are beginning to reject the traditional Mexican notion of masculine superiority. The word machismo is derived from macho, which means male. The real macho possesses many traits of honor, dignity, and courage. he exemplifies masculine aggressiveness and sexual virility. The negative extremes of machismo center on absolute power in the form of violence and exploitation. Machismo is the underlying cause of family conflicts.

How to improve the diagnosis of eosinophilic esophagitis: Experience from a case series in Mexico.

Soto-Solís, R; Santana-de Anda, K; González-Uribe, N; Gallegos, C; Romo-Aguirre, C; Remes-Troche, J M; Ballesteros-Amozurrutia, M A

Eosinophilic esophagitis (EoE) is a chronic, immune disorder mediated largely by food antigens. It shares nonspecific symptoms with gastroesophageal reflux disease (GERD). EoE is rarely reported in Mexico, perhaps due to the racial characteristics of the population or because of insufficient diagnostic suspicion. Our aim was to describe a Mexican cohort with EoE and evaluate the usefulness of the clinical history and endoscopy in the EoE diagnosis, in comparison with GERD patients. A retrospective study was carried out on the clinical characteristics and endoscopic and histopathologic findings in patients with EoE, along with a case-control study on patients with GERD. The endoscopic images obtained were interpreted in a blind and randomized manner by 4 gastroenterologists, before and after providing them with information on the characteristic alterations of EoE. The esophageal biopsies were also blinded to 2 pathologists that evaluated their diagnostic correlation. The Fisher's exact test and Mann-Whitney U test were used in the statistical analysis. Fourteen patients with EoE were included in the study. Ten (71%) of them were men and the mean age of the patients was 35 years. There were more subjects with a personal history of asthma (p=0.0023) and food impaction (p=0.04) in the EoE group. The initial evaluation of the endoscopic findings showed 53% correct EoE interpretations and rose to 96% in the second revision (sensitivity 100%, specificity 71%, PPV 65%, NPV 100%). Mexican patients with EoE have similar characteristics to those of patients in western case series. Clinical awareness of the disorder increases endoscopic diagnosis in up to 40% of cases.

To assess the potential under-registration of work-related accidents in the Mexican Institute of Social Security. A countrywide cross-sectional study was carried out with information collected from 27 district offices of the Mexican Institute of Social Security (MISS), on workers seen at MISS emergency rooms during November 2001 because of a probable accident at work. We compared these reports to official records of work-related accidents to estimate the proportion of incomplete reports. Data analysis consisted of descriptive statistics for each variable; the annual estimation of incomplete reporting proportions was made by multiplying by twelve months; 95% confidence intervals were estimated using Poisson's exact method for a proportion. Data from 27 out of 37 MISS district offices revealed that 7211 cases were not recognized as work accidents, accounting for an underestimation of 26.3%, ranging between 0 and 68% among the different district offices. The accidents that were most frequently left unregistered were mild and blunt injuries. Under-registration can affect worker compensation plans and the financial balance of the institution's occupational risk insurance. Research is needed to investigate and eliminate the causes of under-registration. Employers, the industry, and health institutions should be involved in this effort.

Late Pleistocene/Holocene craniofacial morphology in Mesoamerican Paleoindians: implications for the peopling of the New World.

2005-12-01

Several studies on craniofacial morphology showed that most Paleoindians, who were the first settlers of the New World, clearly differ from modern Amerindians and East Asians, their supposed descendants and sister group, respectively. Here we present new evidence supporting this view from the Late Pleistocene/Early Holocene horizon from Mexico, as well as from the most complete set of dated Paleoindian remains. We analyzed the phenotypic resemblance of early Mexicans with other South Paleoamerican and modern human series. Two independent approaches to the data were used. In the first case, individual specimens were tested for morphological similarity with a set of modern reference samples. In the second analysis, Mexican specimens were treated as a sample in order to compute minimum genetic distances. Results from both approaches tend to associate early Mexican skulls with Paleoindians from Brazil, an Archaic sample from Colombia, and several circum-Pacific populations. These results give support to a model in which morphologically generalized groups of non-Northeast Asian descent (the so-called Paleoamericans) entered the continent first, and then dispersed from North to South America through Central America. The large geographic dispersal of Paleoamericans, and their presence in Mexico in the Early Holocene, raise new issues about the continent's settlement scenario. 2005 Wiley-Liss, Inc.

The "Paulina case" is the story of a 13-year-old girl in Mexico who became pregnant in 1999 after being raped. Although she received permission to obtain a legal abortion, the hospital convinced her mother through misleading information to decline the abortion. This case has become an almost obligatory point of reference when abortion is discussed in Mexico. This paper analyses how the Mexican press portrayed the Paulina case and the social actors who participated in it--Paulina herself, Paulina's allies, the state government, the Catholic Church, members of the political party PAN and the National Human Rights Commission. One of the great breakthroughs of this case was that the denial of an abortion was judged to be a form of negligence. In demanding justice for Paulina, Paulina's allies were given moral authority in the press to denounce those who denied her an abortion. While the government of Baja California state and members of the PAN were held responsible for their role in the case, the Catholic Church, who was also responsible, seemed to escape criticism. It is probable that the large emotional weight of the Paulina case accomplished more in terms of changing public opinion in support of women's right to decide on abortion than any other single event to date.

Two Decades of Negative Educational Selectivity of Mexican Migrants to the United States

Immigration is commonly considered to be selective of more able individuals. Studies comparing the educational attainment of Mexican immigrants in the United States to that of the Mexican resident population support this characterization. Upward educational-attainment biases in both coverage and measurement, however, may be substantial in U.S. data sources. Moreover, differences in educational attainment by place size are very large within Mexico, and U.S. data sources provide no information on immigrants’ places of origin within Mexico. To address these problems, we use multiple sources of nationally-representative Mexican survey data to re-evaluate the educational selectivity of working-age Mexican migrants to the United States over the 1990s and 2000s. We document disproportionately rural and small-urban-area origins of Mexican migrants and a steep positive gradient of educational attainment by place size. We show that together these conditions induced strongly negative educational selection of Mexican migrants throughout the 1990s and 2000s. We interpret this finding as consistent with low returns to the education of unauthorized migrants and few opportunities for authorized migration. PMID:25995526

Current literature indicates that intimate partner violence is a complex phenomenon that exists worldwide. However, little is known about why some men of Mexican origin abuse women. This descriptive study was conducted to understand the experiences of men of Mexican origin who abuse their intimate partners. A qualitative research design was used to conduct this study in a south Texas border community adjacent to the United States-Mexico border. This study builds on existing research and furthers the knowledge related to the factors contributing to intimate partner violence, including cultural factors. The results also reinforce the negative impacts of intimate partner violence on children and the family structure. Further research is needed to support the development of a culturally appropriate prevention and intervention program for men of Mexican origin who abuse women and their families.

This descriptive study investigates the genetic structure of seven Mexican indigenous populations (Mixteca Alta, Mixteca Baja, Otomies, Purepecha, Nahuas-Guerrero, Nahuas-Xochimilco, and Tzeltales) on the basis of five PCR-based polymorphic DNA loci: LDLR, GYPA, HBGG, D7S8, and GC. Genetic distance and diversity analyses indicate that these Mexican indigenous are similar and that more than 96% of the total gene diversity (H(T)) can be attributed to individual variation within populations. Mixteca-Alta, Mixteca-Baja, and Nahuas-Xochimilco show indications of higher admixture with European-derived persons. The demonstration of a relative genetic homogeneity of Mexican Indians for the markers studied suggests that this population is suitable for studying disease-marker associations in the search for candidate genes of complex diseases.

Canaries in a Coalmine: Immigration and Overweight among Mexican-origin Children in the US and Mexico

PubMed Central

Van Hook, Jennifer; Baker, Elizabeth; Altman, Claire E.; Frisco, Michelle

2011-01-01

The prevalence of overweight is higher for Hispanic children of immigrants than children of natives. This does not fit the pattern of the epidemiological paradox; the widely supported finding that immigrants tend to be healthier than their U.S.-born peers, and it suggests that exposure to the U.S. increases immigrant children’s risk of overweight. This study’s primary contribution is to better assess how exposure to the U.S. environment affects childhood overweight among a homogamous ethnic group, Mexican-Americans. We do so by using an innovative binational study design to compare the weight of Mexican-American children of immigrants, Mexican-American children of natives, and Mexican children in Mexico with different propensities of having immigrant parents. Cross-sectional data are derived from a pooled sample of 9,982 6–19 year old children living in either Mexico or the United States in the early 2000s. Mexican-resident children with a very high propensity to have immigrant parents have significantly lower percentile BMIs and lower odds of overweight than Mexican children with lower propensities of emigration and U.S.-resident Mexican-American children. This suggests that selection into immigration streams does not account for the high prevalence of overweight among children of Mexican immigrants. Rather, U.S. exposure significantly raises children of Mexican immigrants’ risk of being overweight. Moreover, second generation children have the highest percentile BMIs and greatest odds of overweight of all comparison groups, including children of natives. This suggests that they experience risks above and beyond the effects of exposure to American society. PMID:22153862

Acculturative stress negatively impacts maternal depressive symptoms in Mexican-American women during pregnancy

D’Anna-Hernandez, Kimberly L.; Aleman, Brenda; Flores, Ana-Mercedes

2015-01-01

Background Mexican-American women exhibit high rates of prenatal maternal depressive symptoms relative to the general population. Though pregnant acculturated Mexican-American women experience cultural stressors such as acculturation, acculturative stress and discrimination that may contribute to elevated depressive symptoms, the contribution of these socio-cultural correlates to depressive symptomology is unknown. Method Ninety-eight pregnant women of Mexican descent were recruited from a community hospital clinic during their first trimester. Women completed surveys about acculturation, acculturative stress, perceived discrimination, general perceived stress, and maternal depressive symptoms as well as the potential protective factor of Mexican cultural values. Results Women who experienced greater acculturative and perceived stress, but not perceived discrimination or acculturation, reported significantly elevated depressive symptoms during pregnancy. Also, women who experienced greater acculturative stress identified with a mixture of Mexican and American cultural values. However, only the Mexican cultural value of respect was protective against maternal depressive symptoms while adhering to the Anglo value of independence and self-reliance was a risk factor. Limitations A limitation in the study is the cross-sectional and descriptive self-report nature of the work, underscoring the need for additional research. Moreover, physiological measures of stress were not analyzed in the current study. Conclusions Results point to acculturative stress, above other cultural stressors, as a potential intervention target in culturally competent obstetric care. These findings have implications for maternal mental health treatment during pregnancy, which likely affects maternal-fetal programming and may favorably affect perinatal outcomes in the vulnerable Mexican-American population.

A number of studies have investigated use of extreme (ERS) and acquiescent (ARS) response styles across cultural groups. However, due to within-group heterogeneity, it is important to also examine use of response styles, acculturation, and endorsement of cultural variables at the individual level. This study explores relationships between acculturation, six Mexican cultural factors, ERS, and ARS among a sample of 288 Mexican American telephone survey respondents. Three aspects of acculturation were assessed: Spanish use, the importance of preserving Mexican culture, and interaction with Mexican Americans versus Anglos. These variables were hypothesized to positively associate with ERS and ARS. Participants with higher Spanish use did utilize more ERS and ARS; however, value for preserving Mexican culture and interaction with Mexican Americans were not associated with response style use. In analyses of cultural factors, endorsement of familismo and simpatia were related to more frequent ERS and ARS, machismo was associated with lower ERS among men, and la mujer was related to higher ERS among women. Caballerismo was marginally associated with utilization of ERS among men. No association was found between la mujer abnegada and ERS among women. Relationships between male gender roles and ARS were nonsignificant. Relationships between female gender roles and ARS were mixed but trended in the positive direction. Overall, these findings suggest that Mexican American respondents vary in their use of response styles by acculturation and cultural factors. This usage may be specifically influenced by participants' valuing of and engagement with constructs directly associated with social behavior. PMID:21927503

Epidemiological studies on myasthenia gravis (MG) in Mexico is mainly derived from experiences in referral centers. To describe the epidemiological characteristics of hospital discharges during 2010 with the diagnosis of MG in adults hospitalized in the Mexican public health system. We consulted the database of hospital discharges during 2010 of the National Health Information System (Ministry of Health, IMSS, IMSS oportunidades, ISSSTE, PEMEX, and the Ministry of Defense). The MG records were identified by the code G70.0 of the International Classification of Diseases 10th revision. During 2010 there were 5,314,132 hospital discharges (4,254,312 adults). Among them, 587 (0.01%) were adults with MG (median age: 47 years, 60% women). Women with MG were significantly younger than men (median age: 37 vs. 54 years, respectively; p < 0.001). The median hospital stay was six days. The case fatality rate was 3.4%, without gender differences. Age was associated with the probability of death. We confirmed the bimodal age-gender distribution in MG. The in-hospital case fatality rate in Mexico is consistent with recent reports around the world.

The shape of things to come? Obesity prevalence among foreign-born vs. US-born Mexican youth in California

2013-01-01

Obesity among the Mexican-origin adult population in the US has been associated with longer stays in the US and with being US- vs. Mexican-born, two proxies for acculturation. This pattern is less clear for Mexican-origin children and young adults: recent evidence suggests that it may be reversed, with foreign-born Mexican youth in the US at higher risk of obesity than their US-born Mexican–American counterparts. The objective of this study is to evaluate the hypothesis that the immigrant advantage in obesity prevalence for Mexican-origin populations in the US does not hold for children and young adults. We use data from the Los Angeles Family and Neighborhood Survey (N = 1143) and the California Health Interview Survey (N = 25,487) for respondents ages 4–24 to calculate the odds of overweight/obesity by ethnicity and nativity. We find support for the hypothesis that overweight/obesity prevalence is not significantly lower for first-generation compared to second- and third-generation Mexican-origin youth. Significantly higher obesity prevalence among the first generation was observed for young adult males (ages 18–24) and adolescent females (ages 12–17). The previously-observed protective effect against obesity risk among recent adult immigrants does not hold for Mexican-origin youth. PMID:23273875

2007-01-01

Background In 1996, Mexico started to register cases of childhood cancer. Here, we describe the incidence of cancer in children, residing in ten Mexican jurisdictions, who were treated by the Instituto Mexicano del Seguro Social (IMSS). Methods New cases of childhood cancer, which were registered prospectively in nine principal Medical Centers of IMSS during the periods 1998–2000 (five jurisdictions) and 1996–2002 (five jurisdictions), were analyzed. Personnel were specifically trained to register, capture, and encode information. For each of these jurisdictions, the frequency, average annual age-standardized incidence (AAS) and average annual incidence per period by sex and, age, were calculated (rates per 1,000,000 children/years). Results In total 2,615 new cases of cancer were registered, with the male/female ratio generally >1, but in some tumors there were more cases in females (retinoblastoma, germ cells tumors). The principal groups of neoplasms in seven jurisdictions were leukemias, central nervous system tumors (CNS tumors), and lymphomas, and the combined frequency for these three groups was 62.6 to 77.2%. Most frequently found (five jurisdictions) was the North American-European pattern (leukemias-CNS tumors-lymphomas). Eight jurisdictions had AAS within the range reported in the world literature. The highest incidence was found for children underless than five year of age. In eight jurisdictions, leukemia had high incidence (>50). The AAS of lymphomas was between 1.9 to 28.6. Chiapas and Guerrero had the highest AAS of CNS tumors (31.9 and 30.3, respectively). The frequency and incidence of neuroblastoma was low. Chiapas had the highest incidence of retinoblastoma (21.8). Germ-cell tumors had high incidence. Conclusion The North American-European pattern of cancers was the principal one found; the overall incidence was within the range reported worldwide. In general but particularly in two jurisdictions (Yucatán and Chiapas), it will be necessary to carry out studies concerning the causes of cancer in children. Due to the little that is known about the incidence of cancer in Mexican children, it will be necessary to develop a national program to establish a cancer registry for the whole of the country.

Objectives: Meningococcal meningitis is reported as a rare condition in Mexico. There are no internationally published studies on bacterial causes of meningitis in the country based on active surveillance. This study focuses on finding the etiology of bacterial meningitis in children from nine Mexican Hospitals. Methods: From January 2010 to February 2013, we conducted a three years of active surveillance for meningitis in nine hospitals throughout Mexico. Active surveillance started at the emergency department for every suspected case, and microbiological studies confirmed/ruled out all potentially bacterial pathogens. We diagnosed based on routine cultures from blood and cerebrospinal fluid (not polymerase chain reaction or other molecular diagnostic tests), and both pneumococcal serotyping and meningococcal serogrouping by using standard methods. Results: Neisseria meningitidis was the leading cause, although 75% of cases occurred in the northwest of the country in Tijuana on the US border. Serogroup C was predominant. Streptococcus pneumoniae followed Neisseria meningitides, but was uniformly distributed throughout the country. Serotype 19A was the most incident but before universal implementation of the 13-valent pneumococcal conjugate vaccine. Other bacteria were much less common, including Enterobacteriaceae and Streptococcus agalactiae (these two affecting mostly young infants). Conclusions: Meningococcal meningitis is endemic in Tijuana, Mexico, and vaccination should be seriously considered in that region. Continuous universal vaccination with the 13-valent pneumococcal conjugate vaccine should be nationally performed, and polymerase chain reaction should be included for bacterial detection in all cultures – negative but presumably bacterial meningitis cases.

This study examined whether Mexican-American parent’s experiences with discrimination are related to adolescent psychological adjustment over time. The extent to which associations between parent discrimination and adolescent adjustment vary as a function of parent’s ethnic socialization of their children was also examined. Participants included 344 high school students from Mexican or Mexican-American backgrounds (primarily second generation; ages 14 – 16 at Wave 1) and their primary caregivers who completed surveys in a two-year longitudinal study. Results revealed that parent discrimination predicted internalizing symptoms and self-esteem among adolescents, one year later. Additionally, adolescents were more likely to report low self-esteem in relation to parents’ increased experiences of discrimination when parents conveyed ethnic socialization messages to them.

The purpose of the study was to examine the prevalence and determinants of prediabetes, undiagnosed diabetes, and diabetes among Mexican adults from a subsample of the Mexican Health and Aging Study. We examined 2012 participants from a subsample of the Mexican Health and Aging Study. Measures included sociodemographic characteristics, body mass index, central obesity, medical conditions, cholesterol, high-density lipoprotein cholesterol, hemoglobin A1c, and vitamin D. Logistic regression was performed to identify factors associated with prediabetes, undiagnosed diabetes, and self-reported diabetes. Prevalence of prediabetes, undiagnosed, and self-reported diabetes in this cohort was 44.2%, 18.0%, and 21.4%, respectively. Participants with high waist-hip ratio (1.61, 95% confidence interval [CI] = 1.05-2.45) and high cholesterol (1.85, 95% CI = 1.36-2.51) had higher odds of prediabetes. Overweight (1.68, 95% CI = 1.07-2.64), obesity (2.38, 95% CI = 1.41-4.02), and high waist circumference (1.60, 95% CI = 1.06-2.40) were significantly associated with higher odds of having undiagnosed diabetes. Those residing in a Mexican state with high U.S. migration had lower odds of prediabetes (0.61, 95% CI = 0.45-0.82) and undiagnosed diabetes (0.53, 95% CI = 0.41-0.70). Those engaged in regular physical activity had lower odds of undiagnosed diabetes (0.74, 95% CI = 0.57-0.97). There is a high prevalence of prediabetes and undiagnosed diabetes among Mexican adults in this subsample. Findings suggest the need for resources to prevent, identify, and treat persons with prediabetes and undiagnosed diabetes. Copyright © 2016 Elsevier Inc. All rights reserved.

Effect of acculturation and mutuality on family loyalty among Mexican American caregivers of elders.

Kao, Hsueh-Fen S; An, Kyungeh

2012-06-01

Informal family care for elders is conventional in Mexican American communities despite increasing intergenerational gaps in filial values. In our study, we explored whether acculturation and dyadic mutuality, as perceived by Mexican American family caregivers, explain the caregivers' expectations of family loyalty toward elderly relatives. A nonexperimental, correlational design with convenience sampling was used in El Paso, Texas, from October 2007 to January 2008. Three bilingual promotoras collected data from 193 Mexican American adult caregivers of community-dwelling elders using three scales designed for Mexican Americans: the Acculturation Rating Scale for Mexican Americans II-Short Form, the Mutuality Scale, and the Expectations of Family Loyalty of Children Toward Elderly Relatives Scale. Confirmatory factor analysis was used to analyze the data. Acculturation had a marginal effect (r = .21, p < .05), but mutuality presented a strong correlation (r = .45, p < .001) with the expectations of family loyalty toward elderly relatives. There was no significant correlation between acculturation and mutuality (r = .05). Although Mexican American caregivers with strong Mexican orientation may have high expectations of family loyalty toward elderly relatives, mutuality exhibits more significant effects on expectations. Among Mexican Americans, mutuality between the caregiving dyad, as perceived by caregivers, may be a better predictor of filial values than caregivers' acculturation alone. It may be useful to incorporate the dual paradigm of acculturation and mutuality into immigrant family care for elderly relatives. © 2012 Sigma Theta Tau International.

Patterns of contraceptive use among Mexican-origin women.

PubMed

White, Kari L; Potter, Joseph E

Mexican women in the United States (US) have higher rates of fertility compared to other ethnic groups and women in Mexico. Whether variation in women's access to family planning services or patterns of contraceptive use contributes to this higher fertility has received little attention. We explore Mexican women's contraceptive use, taking into account women's place in the reproductive life course. Using nationally representative samples from the US (National Survey of Family Growth) and Mexico (Encuesta National de la Dinámica Demográfica), we compared the parity-specific frequency of contraceptive use and fertility intentions for non-migrant women, foreign-born Mexicans in the US, US-born Mexicans, and whites. Mexican women in the US were less likely to use IUDs and more likely to use hormonal contraception than women in Mexico. Female sterilization was the most common method among higher parity women in both the US and Mexico, however, foreign-born Mexicans were less likely to be sterilized, and the least likely to use any permanent contraceptive method. Although foreign-born Mexicans were slightly less likely to report that they did not want more children, differences in method use remained after controlling for women's fertility intentions. At all parities, foreign-born Mexicans used less effective methods. These findings suggest that varying access to family planning services may contribute to variation in women's contraceptive use. Future studies are needed to clarify the extent to which disparities in fertility result from differences in contraceptive access.

The study aimed to analyze the costs of medical care for mental disorders in the Mexican health system. This was a retrospective cross-sectional evaluation study. As markers for the problem, the study selected two of the principal psychological processes in mental disorders in recent years: depression and schizophrenia. Annual accumulated incidence was identified based on epidemiological reporting by type of institution in 2005-2013. The mean annual case management cost was determined with the instrumentation and consensus technique, identifying the production functions, types of inputs, costs, and amounts of inputs ordered, concentrated in the mean case matrix. Finally, an econometric adjustment factor was applied to control the inflationary effect for each year in the study period. Mean annual case management cost was USD 2,216.00 for schizophrenia and USD 2,456.00 for depression. All the institutions in the Mexican health system showed upward and constant epidemiological and economic trends. The total cost for the two disorders in the last year of the period (2013) was USD 39,081,234.00 (USD 18,119,877.00 for schizophrenia and USD 20,961,357.00 for depression). The largest impact for the two disorders combined was in institutions serving the population without health insurance (USD 24,852,321.00) versus the population with private insurance (USD 12,891,977.00). The cost of meeting the demand for services for the two disorders differs considerably between institutions that treat the population with private health service versus the population without, and is higher in the latter. The study's epidemiological and economic indicators provide evidence for decision-making in the use and allocation of healthcare resources for these two disorders in the coming years.

Genotypes were determined for 64 single nucleotide polymorphisms, and a possible association was examined between those genotypes and type 2 diabetes and other quantitative traits, after adjusting for age, sex and body mass index. In the case-pediatric control and case-adult control analyses, five polymorphisms were associated with increased likelihood of pediatric-onset type 2 diabetes; only one of these polymorphisms (CADM2/rs1307880) also showed a consistent effect in the case-sibling analysis. The associations in the combined analysis were as follows: ADORA1/rs903361 (OR 1.9, 95% CI 1.2; 3.0); CADM2/rs13078807 (OR 2.2, 95% CI 1.2; 4.0); GNPDA2/rs10938397 (OR 2.2, 95% CI 1.4; 3.7); VEGFA/rs6905288 (OR 1.4, 95% CI 1.1; 2.1) and FTO/rs9939609 (OR 1.8, 95% CI 1.0; 3.2). We also identified 16 polymorphisms nominally associated with quantitative traits in participants without diabetes. ADORA/rs903361, CADM2/rs13078807, GNPDA2/rs10938397, VEGFA/rs6905288 and FTO/rs9939609 are associated with an increased risk of pediatric-onset type 2 diabetes in the Mexican population.

Social class, Mexican culture, and fatalism: their effects on psychological distress.

We examine the causes and consequences of fatalism in a cross-cultural setting, focusing on the ways in which a fatalistic world view may mediate the effects of social class and Mexican ethnic identity on psychological distress. We find that persons in the lower social classes and Mexicans tend to be more fatalistic than persons in the upper classes and Anglos, and that fatalism, in turn, increases psychological distress. We attempt to integrate research on the social and cultural determinants of cognitive orientations with studies of the effects of social class and Mexican culture on distress.

Drawing on cultural –ecological and person –environment fit perspectives, this study examined links among Mexican-American adolescents’ time with peers and parents, parents’ cultural orientations, and adolescents’ psychosocial adjustment and cultural orientations. Participants were 492 Mexican-American adolescents (Ms = 15.7 and 12.8 years for older siblings and younger siblings) and their parents in 246 families. Family members described their family relationships, cultural orientations, and psychosocial functioning in home interviews, and time-use data were collected during a series of nightly phone calls. Mexican-American adolescents spent the majority of their peer time with Mexican youth. Some support was found for the hypothesis that the mismatch between parents’ cultural orientations and adolescents’ peer involvement is linked to adolescents’ psychosocial functioning. PMID:16999812

This analysis explores nativity differences in depressive symptoms among very old (75+) community-dwelling Mexican Americans. Cross-sectional analysis using the fifth wave (2004-2005) of the Hispanic Established Population for the Epidemiological Study of the Elderly (Hispanic EPESE). The sample consisted of 1699 non-institutionalized Mexican American men and women aged 75 years and above. Depressive symptoms were measured by the Center for Epidemiological Studies Depression Scale (CES-D). Logistic regression was used to predict high depressive symptoms (CES-D score 16 or higher) and multinomial logistic regression was used to predict sub-threshold, moderate, and high depressive symptoms. Results showed that elders born in Mexico had higher odds of more depressive symptoms compared to otherwise similar Mexican Americans born in the US. Age of arrival, gender, and other covariates did not modify that risk. The findings suggest that older Mexican American immigrants are at higher risk of depressive symptomatology compared to persons born in the US, which has significant implications for research, policy, and clinical practice.

Internalization of U.S. female beauty standards as a mediator of the relationship between Mexican American women's acculturation and body dissatisfaction.

Poloskov, Elizabeth; Tracey, Terence J G

2013-09-01

The relationships among acculturation, internalization of U.S. sociocultural standards of female beauty, and body dissatisfaction were examined in a sample of 211 Mexican American college women. Structural equation modeling was used to identify the paths among these three factors. Results demonstrated that there are two distinct types of body dissatisfaction: global evaluations and composite site-specific evaluations. The relationships between acculturation toward dominant U.S. culture and both types of body dissatisfaction were found to be fully mediated by internalization of U.S. standards of female beauty. There were no relationships between Mexican orientation and any of the study variables. The results from this study imply that it is important for therapists working with Mexican American female clients to assess the client's level of acculturation, examine the cultural (U.S. and Mexican) messages the client receives, and explore how these messages impact her body image.

Photoacoustic methodology in the transmission configuration (PMTC) was used to study the thermophysical properties and their relation with the composition in Mexican citrus essential oils providing the viability of using photothermal techniques for quality control and for authentication of oils and their adulteration. Linear relations for the amplitude (on a semi-log scale) and phase, as functions of the sample's thickness, for the PMTC was obtained through a theoretical model fit to the experimental data for thermal-diffusivity measurements in Mexican orange, pink grapefruit, mandarin, lime type A, centrifuged essential oils, and Mexican distilled lime essential oil. Gas chromatography for distilled lime essential oil and centrifuged lime essential oil type A is reported to complement the study. Experimental results showed close thermal-diffusivity values between Mexican citrus essential oils obtained by centrifugation, but a significant difference of this physical property for distilled lime oil and the corresponding value obtained by centrifugation, which is due to their different chemical compositions involved with the extraction processes.

Psychological distress among low-income U.S.- and foreign-born women of Mexican descent: impact of acculturation.

Bekteshi, Venera; Xu, Qingwen; Van Tran, Thanh

2015-01-01

After testing the capacity of Kessler's psychological distress (K6) scale to measure equally across low-income Mexican-born women (n=881) and U.S.-born women of Mexican descent (n=317), this study assesses the impact of acculturation on this group's psychological distress. We employ descriptive and confirmatory factor analyses to test the cross-cultural equivalence of K6. Multivariate and logistic regression is used to test the association between acculturation and psychological distress among low-income, Mexican-American women. The cross-cultural equivalence analysis shows that some of the scale's items have the capacity to measure psychological distress equally among participants. Regression results indicate that the more acculturated these women become, the greater their psychological distress is. The study recommends that researchers emphasize the cross-cultural equivalence of their measures and suggests a heightened awareness among practitioners of the multidimensional impact of acculturation on clients of Mexican descent.

2016-01-01

Although numerous studies of non-Hispanic whites and blacks show that social integration and social support tend to favor longevity, it is unclear whether this general pattern extends to the Mexican American population. Building on previous research, we employed seven waves of data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly to examine the association between perceived social support trajectories and the all-cause mortality risk of older Mexican Americans. Growth mixture estimates revealed three latent classes of support trajectories: high, moderate, and low. Cox regression estimates indicated that older Mexican American men in the low support trajectory tend to exhibit a higher mortality risk than their counterparts in the high support trajectory. Social support trajectories were unrelated to the mortality risk of older Mexican American women. A statistically significant interaction term confirmed that social support was more strongly associated with the mortality risk of men. PMID:26966256

Parental practices and beliefs have been recognized as having an important influence on the development of children's self-regulation. Using a mixed methods approach, the present study explored how parental practices and beliefs influence low-income Mexican American children's (N = 44) self-regulation during the fall of preschool. Quantitative results indicated that the family learning environment and parental control were significantly related to stronger self-regulation in Mexican American children from low-income families. Qualitative interviews indicated that "respect" and "being well educated" emerged as key factors guiding parents' expectations of children's behaviors and discipline. Additionally, these results indicated that parents struggled to provide additional educational materials to enrich the home learning environment of their children. This study highlights the importance of understanding the parental practices and beliefs of low-income Mexican American parents and their influence on children's self-regulation to better serve the needs of Mexican American parents and their children. © 2017 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Rates of breast cancer (BC) have increased in Mexico, with the highest incidence and mortality rates observed in the northern Mexican states. This study aimed to describe the BC knowledge, attitudes and screening practices among Mexican women with and without a family history of BC residing along the Mexico-US border, and identify factors associated with screening behaviors. One hundred and twenty eight Mexican women aged 40 and older completed an interviewer-administered questionnaire on sociodemographic characteristics, knowledge, family history, and screening practices. There were no significant differences between Mexican women with and without a family history. Over 60% of women in both groups had never had a mammogram/breast ultrasound, and more than 50% had never obtained a clinical breast exam. Age, marital status, insurance, and breast cancer knowledge significantly influenced BC screening behaviors among Mexican women. Further research is needed to examine other key factors associated with screening utilization, in effort of improving BC rates.

To estimate the indirect costs generated by adults with cancer in Mexico from 2002-2020. Using information from national sources and the national cancer incidence from GLOBOCAN, we estimated income lost due to premature death (ILPD), short-term benefits (STBs), disability pensions (DPs), and opportunity costs for the carer (OCCs) generated by patients with cancer. Amounts were reported in Mexican pesos. We estimated 23 359 deaths and 216 679 new cases of cancer by 2020, which would be associated with a total indirect cost of 20.15 billion Mexican pesos. Men are expected to generate 54.9% of these costs. ILPD is expected to comprise the highest percentage of the cost (60%), followed by OCCs (22%), STBs (17%) and DPs (1%). From an economic perspective, the results emphasize the need to strengthen preventive interventions and early detection of cancer among adults to reduce its effect on the productivity of Mexico.

[The homosexual transmission of HIV/AIDS in Mexico].

To analyze HIV homosexual transmission in Mexico, epidemic trends and biological and social risk factors. This analysis is based on 19,090 notifications of AIDS cases and on a review of two previous studies that include 3,029 behavioral interviews (together with HIV serological screening tests) carried out at the Information Center of the Mexican Council for Control and Prevention of AIDS (CONASIDA) (1988-89) and during a 1988 study in six Mexican cities. Cities were included because they were the larger in the country and/or because they were the larger in the country and/or because they were touristic places (Mexico City, Guadalajara, Monterrey, Acapulco, Tijuana and Merida). Logistic regressions were used to estimate the odds ratios for HIV seropositivity and for condom use. Seventy-two percent of the total reported AIDS cases (19,090) up to June 30, 1994, were associated with male homosexual behaviors. In absolute numbers, cases under this category exhibited a rising trend until the end of 1993. HIV seroprevalence was 31% in 2,314 men with homosexual practices who attended "FLORA", the AIDS Information Center in Mexico, from January 1988 to June 30, 1989. The main predictive variables for seropositivity were exclusive homosexual behavior, more than 40 lifetime sexual partners, mixed sexual behavior (both insertive and receptive and intercourse), sex with a person with AIDS, history of syphilis, and anal or genital warts. In general, these risk factors (data from the Information Center) are similar to those found in the six Mexican cities study. There were significant differences in HIV prevalence among the high-risk city samples (the highest in Mexico City with 25% and the lowest in Monterrey with 2.4%). Reported condom use was very low in both studies: only 5% used a condom in all of their sexual relationships. A statistically significant protective effect for HIV infection was found only for those who reported using a condom in all sexual encounters. In the six cities study, city of residence was a strong predictor of condom use. HIV homosexual transmission is steadily increasing; the recent decline in the percentage of homosexual cases is artificial because of the increment of cases under other categories. Men who report exclusive homosexual behavior have higher prevalence rates of infection than bisexual men. Individuals with insertive/receptive behavior (mixed) have the highest risk for HIV seropositivity, mainly because of sociological, rather than biological reasons. This difference in risks for HIV and condom use may be related to the selection of sexual partners from specific social networks. Condom use was demonstrated to be an effective method for preventing HIV seropositivity among those who always use condoms. However, it is alarming that only 5% of respondents reported condom use in all sexual encounters. Social and geographic differences in the cumulative numbers of cases, HIV prevalence, sexual practices and condom use must be taken into account in the planning of preventive programs.

This study compares the environmental performance of Mexican banknotes printed on high-durability cotton paper (HD paper) and thermoplastic polymer (polymer) through a life cycle assessment to appraise the environmental impacts from the extraction of raw materials to the final disposal of the banknotes. The functional unit was defined considering the next parameters: 1) lifespan of the banknotes, stablished in 31.5 and 54months for HD paper and polymer, respectively; 2) denomination, selecting $200 pesos banknotes; 3) a 5year time frame and 4) a defined amount of money, in this case stablished as the monthly cash supply of an average Mexican household, equaling $12,708 pesos. Accordingly, 121 pieces for the HD paper and 71 pieces for the polymer banknotes were analyzed. The results favor the banknotes printed on polymer substrate primarily because of the longer lifespan of this type of material; however, there is a considerable environmental impact in the stages of distribution, followed by the extraction of the raw materials (crude oil) during manufacturing. Regarding the HD cotton paper, the major impact corresponds to extraction of the raw materials, followed by the distribution of the banknotes. The inclusion of the automatic teller machines (ATMs) in the life cycle assessment of banknotes shows that the electricity required by these devices became the largest contributor to the environmental impacts. Additionally, the sensitivity analysis that the average lifetime of the banknotes is a determining factor for the environmental impacts associated with the whole life cycle of this product. The life cycle stages that refer to the extraction of the raw materials, combined with the average lifetime of the banknotes and the electricity required during the usage stage, are determining factors in the total environmental impact associated with Mexican banknotes.

Complications of diabetes comprise the leading cause of death in Mexico. We aimed to describe the characteristics of management and achievement of therapeutic targets in Mexican patients with diabetes mellitus. We analyzed data from 2642 Mexican patients with type 1 (T1D, n=203, 7.7%) and type 2 diabetes (T2D, n=2439, 92.3%) included in the third wave of the International Diabetes Management Practices Study. Of T2D patients, 63% were on oral glucose-lowering drugs (OGLD) exclusively (mostly metformin), 11% on insulin, 22% on OGLD plus insulin, and 4% on diet and exercise exclusively. T2D patients on insulin were more likely to be trained on diabetes, but they were older, had worse control, longer disease duration and more chronic complications than patients on OGLD only. Glycated hemoglobin (HbA1c) <7% was achieved by 21% and 37% of T1D and T2D patients, respectively. Only 5% of T1D and 3% of T2D attained the composite target of HbA1c <7%, blood pressure <130/80 mmHg and low-density lipoprotein cholesterol <100 mg/dl. T1D patients had less macrovascular but more microvascular complications, compared with T2D patients. Late complications increased with disease duration, so that about 80% of patients after 20 years of diagnosis have at least one late complication. Reaching the target HbA1c <7% was associated with a reduced number of microvascular but not with less macrovascular complications. A great proportion of these Mexican patients with diabetes did not reach therapeutic targets. Insulin was used mostly in complicated cases with advanced disease. Copyright © 2011 SEEN.

Migration and population movement are increasingly viewed as important factors associated with HIV transmission risk. With growing awareness of the potential impact of migration on HIV transmission, several perspectives have emerged that posit differing dynamics of risk. We considered available data on the role of migration on HIV transmission among Mexican migrants in New York City and Puebla, Mexico. Specifically, we examined 3 distinct models of migratory dynamics of HIV transmission—namely, the structural model, the local contextual model, and the interplay model. In doing so, we reframed current public health perspectives on the role of migration on HIV transmission. PMID:24825203

Personality traits have been associated consistently with health-related outcomes, but less is known about how aspects of the sociocultural environment modify these associations. This study uses a sample of participants of Mexican origin (N = 1013) to test whether exposure to the United States, indexed by nativity (Mexicans living in Mexico, foreign-born Mexican Americans, and U.S.-born Mexican Americans), moderates the association between personality traits and body mass index (BMI). Higher Conscientiousness was associated with lower BMI, regardless of nativity. In contrast, the association between Neuroticism and BMI was moderated by exposure to the U.S.: Neuroticism was associated with higher BMI among U.S.-born Mexican Americans (partial r = .15) but not among Mexican participants (partial r = .00), an effect strongest and most robust for the impulsivity facet of Neuroticism. This finding suggests that with more exposure to the United States, those who are more emotionally impulsive are at greater risk for obesity. More broadly, these findings suggest that social and psychological vulnerabilities interact to contribute to health outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

Smoking selectivity among Mexican immigrants to the United States using binational data, 1999-2012.

Mexican immigrants have lower smoking rates than US-born Mexicans, which some scholars attribute to health selection-that individuals who migrate are healthier and have better health behaviors than their non-migrant counterparts. Few studies have examined smoking selectivity using binational data and none have assessed whether selectivity remains constant over time. This study combined binational data from the US and Mexico to examine: 1) the extent to which recent Mexican immigrants (<10years) in the US are selected with regard to cigarette smoking compared to non-migrants in Mexico, and 2) whether smoking selectivity varied between 2000 and 2012-a period of declining tobacco use in Mexico and the US. We combined repeated cross-sectional US data (n=10.901) on adult (ages 20-64) Mexican immigrants and US-born Mexicans from the 1999/2000 and 2011/2012 National Health Interview Survey, and repeated cross-sectional Mexican data on non-migrants (n=67.188) from the 2000 Encuesta Nacional de Salud and 2012 Encuesta Nacional de Salud y Nutrición. Multinomial logistic regressions, stratified by gender, predicted smoking status (current, former, never) by migration status. At both time points, we found lower overall smoking prevalence among recent US immigrants compared to non-migrants for both genders. Moreover, from the regression analyses, smoking selectivity remained constant between 2000 and 2012 among men, but increased among women. These findings suggest that Mexican immigrants are indeed selected on smoking compared to their non-migrating counterparts, but that selectivity is subject to smoking conditions in the sending countries and may not remain constant over time.

Reproductive habitus, psychosocial health, and birth weight variation in Mexican immigrant and Mexican American women in south Texas.

PubMed

Fleuriet, K Jill; Sunil, T S

2015-08-01

The Latina Paradox, or persistent, unexplained variation in low birth weight rates in recently immigrated Mexican women and the trend toward higher rates in subsequent generations of Mexican American women, is most often attributed to unidentified sociocultural causes. We suggest herein that different disciplinary approaches can be synthesized under the constructs of reproductive habitus and subjective social status to identify influences of sociocultural processes on birth weight. Reproductive habitus are "modes of living the reproductive body, bodily practices, and the creation of new subjects through interactions between people and structures" (Smith-Oka, 2012: 2276). Subjective social status infers comparison of self to others based on community definitions of status or socioeconomic status (Adler 2007). We present results from a prospective study of low-income Mexican immigrant and Mexican American women from south Texas that tested the ability of reproductive habitus and subjective social status to elucidate the Latina Paradox. We hypothesized that reproductive habitus between Mexican immigrant women and Mexican American women inform different subjective social statuses during pregnancy, and different subjective social statuses mediate responses to psychosocial stressors known to correlate with low birth weight. Six hundred thirty-one women were surveyed for psychosocial health, subjective social status, and reproductive histories between 2011 and 2013. Eighty-three women were interviewed between 2012 and 2013 for status during pregnancy, prenatal care practices, and pregnancy narratives and associations. Birth weight was extracted from medical records. Results were mixed. Subjective social status and pregnancy-related anxiety predicted low birth weight in Mexican immigrant but not Mexican American women. Mexican immigrant women had significantly lower subjective social status scores but a distinct reproductive habitus that could explain improved psychosocial health during pregnancy. Results underscore the importance of a biopsychosocial, mixed methods approach that integrates anthropology, psychology, and epidemiology in the effort to understand the complex dynamic between sociocultural processes and birth weight.

Craniofacial Secular Change in Recent Mexican Migrants.

Spradley, Katherine; Stull, Kyra E; Hefner, Joseph T

2016-01-01

Research by economists suggests that recent Mexican migrants are better educated and have higher socioeconomic status (SES) than previous migrants. Because factors associated with higher SES and improved education can lead to positive secular changes in overall body form, secular changes in the craniofacial complex were analyzed within a recent migrant group from Mexico. The Mexican group represents individuals in the act of migration, not yet influenced by the American environment, and thus can serve as a starting point for future studies of secular change in this population group. The excavation of a historic Hispanic cemetery in Tucson, Arizona, also allows for a comparison between historic Hispanics and recent migrants to explore craniofacial trends over a broad time period, as both groups originate from Mexico. The present research addresses two main questions: (1) Are cranial secular changes evident in recent Mexican migrants? (2) Are historic Hispanics and recent Mexican migrants similar? By studying secular changes within a migrant population group, secular trends may be detected, which will be important for understanding the biological variation of the migrants themselves and will serve as a preliminary investigation of secular change within Mexican migrants. The comparison of a sample of recent Mexican migrants with a historic Hispanic sample, predominantly of Mexican origin, allows us to explore morphological similarities and differences between early and recent Mexicans within the United States. Vault and face size and a total of 82 craniofacial interlandmark distances were used to explore secular changes within the recent Mexican migrants (females, n = 38; males, n = 178) and to explore the morphological similarities between historic Hispanics (females, n = 54; males, n = 58) and recent migrants. Sexes were separated, and multivariate adaptive regression splines and basis splines (quadratic with one knot) were used to assess the direction and magnitude of secular trends for the recent Mexican migrants. Because dates of birth were unavailable for the historic sample, partial least squares discriminant analysis (PLS-DA) was used to evaluate morphological differences between historic and recent Mexican migrant samples. The data were separated into a training data set and a testing data set to ensure realistic results. Males had eight variables (four positive and four negative) and females had six variables (two positive and four negative) that demonstrated significant differences over time. In the PLS-DA, three components were identified as important in model creation and resulted in a classification accuracy of 87% when applied to a testing sample. The high classification accuracy demonstrates significant morphological differences between the two groups, with the historic Hispanic sample displaying overall larger craniofacial dimensions. While differences in cranial morphology are evident between historic Hispanics and recent Mexican migrants, relatively few positive and negative secular trends were detected within the recent migrant sample.

Social desirability, while a recognized source of respondent bias among Mexican-Americans, has not been evaluated as an explanation for the lower rate of high expressed emotion (EE) found in the family members of Mexican-Americans versus Caucasians with schizophrenia. In this study, we tested the hypothesis that the lower rate of high EE (hostility and criticism) among Mexican-Americans was the result of cultural factors impacting on how information was reported by the Mexican-American relative of a patient with schizophrenia. We compared the ratings of EE between Caucasian (N = 17) and Mexican-American (N = 44) patients with schizophrenia or schizoaffective disorder and their key relatives using the level of expressed emotion (LEE) scale (paper and pencil instrument rated by the patient and relative separately) and the Five Minute Speech Sample (observational experimenter rated). The ability of the various measures to predict relapse over two years was also examined. Contrary to our hypothesis, there were no differences between patient and family measures within ethnic group. Mexican-American patients and relatives reported lower rates of high EE than Caucasians across all measures. High EE predicted relapse across measures for Caucasian participants, but did not predict relapse for Mexican-Americans on any of the measurement instruments. We discuss the implications of these findings on cross-cultural research and family interventions for individuals with psychotic disorders.

Neuroticism is associated with greater susceptibility to the adverse effects of stress and greater exposure to the stressors associated with acculturation in U.S. born Mexican Americans. Neuroticism and acculturation have been associated with injury to crucial stress response systems and are known risk factors for certain mood and anxiety disorders. The purpose of the current study was to examine the effects of neuroticism, and acculturation on the cortisol awakening response (CAR) in healthy Mexican-American adults. Salivary cortisol samples were collected at awakening and 30, 45, and 60 min thereafter, on two consecutive weekdays from 59 healthy Mexican American adult males (26) and females (33), ages 18 to 38 years. Participants were assessed for level of neuroticism and acculturation. Data were analyzed using a mixed effects regression model with repeated measures at four time points. Results showed a significant Neuroticism×Acculturation×Time interaction. The CAR was virtually eliminated in highly acculturated Mexican Americans with greater Anglo orientation and high neuroticism compared with less acculturated Mexican Americans with greater Mexican orientation and lower neuroticism. Findings suggest that some Mexican Americans with high levels of neuroticism may be particularly susceptible to certain challenges and stressors associated with acculturation leading over time to the development of allostatic load, desensitization of the Hypothalamic CRF system and attenuation of the CAR.

To identify, measure and compare the performance indicators of productivity, effective access and quality service for the early detection breast cancer program in Mexico. By means of a study case based on the 2011 Women Cancer Information System (SICAM), the indicators were measured and compared with the Mexican official standard NOM-041-SSA2-2011 and international standards. The analysis showed insufficient installed capacity (37%), low coverage in screening (15%), diagnostic evaluation (16%), biopsy (44%) and treatment (57%), and very low effectiveness in confirmed cases by the total number of screening mammograms performed (0.04%). There was no information available, from SICAM, to estimate the rest of the indicators proposed. Efficient health information systems are required in order to monitor indicators and generate performance observatories of screening programs.

Attitudes of Mexican geneticists towards prenatal diagnosis and selective abortion.

1998-02-03

Prenatal diagnosis (PD) provides the physician information on whether the unborn fetus has a genetic or chromosomal disorder, and offers patients a new option: selective abortion. In the present study, we analyzed the answers Mexican geneticists provided to a few selected questions from a multinational survey designed by Wertz and Fletcher [1988: Am J Hum Genet 42:592-600]. The selected questions were related to the use of PD, the acceptance of selective abortion, and the self-reported directiveness of counselling following the diagnosis of a fetal anomaly. Our results show that the great majority of Mexican geneticists participating in the study agree with PD when medically indicated, but not on free demand. Specific cases stimulated the group on thinking more than the general statements provided in the survey. Although the majority agreed that PD should be available to all women, when faced with cases of nonmorbid maternal anxiety, paternity testing, and sex selection, the proportion of geneticists willing to perform the test decreased substantially. When counselling patients on a fetal anomaly, the minority would be as unbiased as possible, and this seems to be the tendency in developing countries where counselling, as stated in the respondents' comments, reflects the belief that the goal of genetics is the prevention of or opposition to abortion. Counselling was influenced by the severity of the disorder. The geneticists' personal attitude toward abortion in the same situations was stronger than when counselling others. Analysis of directiveness in counselling for fetal anomaly showed that older geneticists, with more years of experience in medical genetics, were more likely to be neutral. When counselling directively, the group showed an overall direction toward continuing affected pregnancies. However, older geneticists and those with more than 10 years of practice were more likely than their younger counterparts to counsel towards terminating affected pregnancies. In personal situations of fetal disorder, the general tendency was to abort; however, geneticists seeing more than 5 patients per week, and those who believe that religion is important, were more likely to reject abortion. The sample is representative of Mexican geneticists, and the main limitation of this study is that the geneticists have very little experience in PD, and that their responses were mostly based on theory. However, their opinions may influence the demand and the availability of PD and abortion, as well as the possibility of legalization of abortion on the basis of a fetal defect.

Childhood obesity has increased to epidemic levels and is considered a public health problem due to its association with a number of metabolic abnormalities, which are being detected at earlier stages of life. The objective was to evaluate the association between the presence of subclinical metabolic abnormalities (SMA) and obesity in a sample of pre-pubertal Mexican schoolchildren. Children of both sexes and 6 to 13 years old were questioned for signs of puberty, underwent anthropometric measurement and had their Body Mass Index (BMI) calculated. Two groups were formed: those with obesity (case group) and those with normal weight paired by age and chosen randomly (control group). Fasting insulin, glucose and cholesterol were measured. 92 children were included, 46 in each group, mean age 9.9 and 9.5 years old, respectively (p = 0.97). A higher frequency of hyperinsulinism was found in the case group: Fasting insulin > 15 mU/ml, 75% vs. 21% (case group vs. control group, respectively); fasting glucose to insulin ratio < 6, 72% vs. 24%; HOMA IR > 2.7, 83% vs. 14%; and decrease in QUICKI (< 0.3), 80% vs. 19% (p = 0.000). Hypercholesterolemia was 25% vs. 15% (p = 0.22), impaired fasting glucose 28% vs. 8% (p = 0.01), and family history of diabetes mellitus (DM) 35% vs. 9% (OR = 5.6; 95% CI = 1.5-22.2; p = 0.002). In this sample of Mexican schoolchildren, obesity was associated to a higher frequency of SMA, such as hyperinsulinism and impaired fasting glucose, and to a family history of DM.

Vitamin D is essential for maintaining bone mineralization and calcium homeostasis, and prevents falls and fractures in older adults. Mexico is undergoing an epidemiologic and demographic transition with increasing obesity rates. The study's aim was to determine the association of obesity with serum 25-hydroxyvitamin D [25(OH)D] concentrations in older Mexican adults. Data from 1772 Mexicans, aged ≥50 years, enrolled in a sub-sample of the 3rd wave of the Mexican Health and Aging Study, were included. Serum 25(OH)D concentrations were used to define vitamin D status, and were categorized into tertiles. Body mass index measures were used to categorize older adults into under/normal weight, overweight, and obese groups. Multinomial logistic regression models were used to assess the relationship, adjusting for potential confounders. Approximately 40% and 37% of older Mexican adults were either overweight or obese, respectively. Compared to under/normal weight older Mexicans, obese adults were 1.78 times (95% Confidence Interval (CI) 1.27-2.48) and 1.94 times (95% CI 1.40-2.68) more associated with the first and second tertile concentrations of serum 25(OH)D, respectively. Overweight adults were 1.52 times (95% CI 1.12-2.06) more associated with the second tertile of serum 25(OH)D concentration than under/normal weight adults. Overweight/Obesity was found to be significantly associated with low concentrations of serum 25(OH) in older Mexican adults.

OBJECTIVE: The study was designed to evaluate the association between socioeconomic level (as measured by maternal education, maternal occupation, and monthly family income) and anencephaly. METHODS: The authors conducted a case-control study using data from the Epidemiological Surveillance System Register for Neural Tube Defects for three states of the Mexican Republic: Puebla, Guerrero and the State of Mexico. Mothers of 151 cases of infants born with anencephaly and mothers of 151 control infants born during the period March 2000 to February 2001 were interviewed about their socioeconomic characteristics and other factors including reproductive history, use of prenatal care, use of tobacco and alcohol, fever during pregnancy, and folic acid supplementation. RESULTS: After adjustment for potential confounders, a risk gradient was seen with decreasing maternal education. Women with less than a primary school education (adjusted odds ratio [OR]=3.0; 95% confidence interval [CI] 1.2, 7.6) and women who had completed primary school but had not completed junior high school (adjusted OR=2.2; 95% CI 0.9, 5.7) had higher risks of giving birth to an infant with anencephaly, compared to women with a higher educational level. A monthly income < or = 1,000 pesos (approximately dollars 100 U.S.) was also associated with a higher risk of anencephaly (OR=2.5; 95% CI 1.2, 5.1). Women employed in industry or agriculture during the acute risk period (three months prior to conception to one month after conception) had a risk 6.5 times (95% CI 1.4, 29.6) that of professional and business women. CONCLUSIONS: This study helps to identify groups that may be especially vulnerable to this type of congenital malformation so that primary and secondary preventive strategies can be targeted to these groups.

Mirame!/Look at Me! is a substance abuse prevention program for low-income Mexican-American youth aged 9-13 years. The theory-driven curriculum, developed for mass distribution via a satellite television network, features social models who demonstrate cognitive-behavioral skills and display conservative norms regarding substance abuse. An 18-session curriculum contains 5-min videos that are assigned to be followed by discussion and social reinforcement from a teacher or volunteer. This case study reports the program development process and experiences in the initial dissemination of the program through national networks for schools and cable television subscribers.

Beliefs and expectations of family and nursing home care among Mexican-origin caregivers.

2017-01-01

This study examined perceptions of family care, nursing homes, and expectations of future care among 85 Mexican-origin women caregivers, some who lived in Mexico City and some who lived in East Los Angeles, California (East LA). Attitudes of Mexican-born women-living in Mexico City and in East LA-were more similar to each other than those of U.S.-born women. Most caregivers reported a preference for family care and had negative views of institutional care. In addition, despite the negative views about nursing homes, some caregivers expressed a willingness to seek nursing-home care for themselves so as to avoid burdening their children in the future. Findings lend support to the persistence of Mexican cultural values in this sample of Mexican-origin caregiving women, regardless of where they were born.

Filling Gaps in the Acculturation Gap-Distress Model: Heritage Cultural Maintenance and Adjustment in Mexican-American Families.

Telzer, Eva H; Yuen, Cynthia; Gonzales, Nancy; Fuligni, Andrew J

2016-07-01

The acculturation gap-distress model purports that immigrant children acculturate faster than do their parents, resulting in an acculturation gap that leads to family and youth maladjustment. However, empirical support for the acculturation gap-distress model has been inconclusive. In the current study, 428 Mexican-American adolescents (50.2 % female) and their primary caregivers independently completed questionnaires assessing their levels of American and Mexican cultural orientation, family functioning, and youth adjustment. Contrary to the acculturation gap-distress model, acculturation gaps were not associated with poorer family or youth functioning. Rather, adolescents with higher levels of Mexican cultural orientations showed positive outcomes, regardless of their parents' orientations to either American or Mexican cultures. Findings suggest that youths' heritage cultural maintenance may be most important for their adjustment.

This study aimed review studies conducted on Mexican patients diagnosed with gastric cancer and/or diseases associated with its development, in which at least one Mexican institute has participated, and to assess their contributions to the primary and secondary prevention of this disease. A search of the Medline database was conducted using the following keywords: gastric/stomach cancer, Mexico. Studies of the Mexican population were selected in which at least one Mexican Institute had participated and where the findings could support public policy proposals directed towards the primary or secondary prevention of gastric cancer. Of the 148 studies found in the Medline database, 100 were discarded and 48 were reviewed. According to the analysis presented, these studies were classified as: epidemiology of gastric cancer (5/48); risk factors and protectors relating to gastric cancer (9/48); relationship between Helicobacter pylori and pathologies associated with gastric cancer and the development of the disease (16/48); relationship between the Epstein-Barr virus and pathologies associated with gastric cancer and the development of the disease (3/48); molecular markers for the development of diseases associated with gastric cancer and gastric cancer (15/48). Mexico requires a program for the prevention and control of gastric cancer based on national health indicators. This should be produced by a multidisciplinary committee of experts who can propose actions that are relevant in the current national context. The few studies of gastric cancer conducted on the Mexican population in national institutes highlight the poor connection that currently exists between the scientific community and the health sector in terms of resolving this health issue. Public policies for health research should support projects with findings that can be translated into benefits for the population. This review serves to identify national research groups studying gastric cancer in the Mexican population. PMID:24782602

Although many studies have attempted to examine the consequences of Mexico-U.S. migration for Mexican immigrants' health, few have had adequate data to generate the appropriate comparisons. In this article, we use data from two waves of the Mexican Family Life Survey (MxFLS) to compare the health of current migrants from Mexico with those of earlier migrants and nonmigrants. Because the longitudinal data permit us to examine short-term changes in health status subsequent to the baseline survey for current migrants and for Mexican residents, as well as to control for the potential health selectivity of migrants, the results provide a clearer picture of the consequences of immigration for Mexican migrant health than have previous studies. Our findings demonstrate that current migrants are more likely to experience recent changes in health status-both improvements and declines-than either earlier migrants or nonmigrants. The net effect, however, is a decline in health for current migrants: compared with never migrants, the health of current migrants is much more likely to have declined in the year or two since migration and not significantly more likely to have improved. Thus, it appears that the migration process itself and/or the experiences of the immediate post-migration period detrimentally affect Mexican immigrants' health.

Cross-sociocultural group measurement equivalency is an important issue that generally has not been studied in the coping literature. Measurement equivalency of the COPE (Carver, Scheier, & Weintraub, 1989) was assessed across two sociocultural groups, a sample of 100 Anglo middle-class divorced mothers and a sample of 122 low-income Mexican American/Mexican immigrant mothers. A series of restrictive confirmatory factor analyses revealed that seven of the COPE's subscales may be measuring the same underlying construct across populations. However, scores derived from the subscales may not represent the same magnitude of the construct in these two groups. This study makes an important first step in furthering the understanding of coping strategies in low-income Mexican American/Mexican immigrant mothers. This study also illustrates the importance of testing for measurement equivalency before conducting comparative research in disparate populations.

Use of the measurement of medication administration hassles with Mexican American family caregivers.

PubMed

Kao, Hsueh-Fen S; Lynn, Mary R

2009-09-01

This study builds on earlier work on medication administration hassles, minor daily irritants experienced by family caregivers of older relatives, by investigating the feasibility of using the Family Caregiver Medication Administration Hassles Scale (FCMAHS) for use with Mexican American caregivers. Appropriate medication administration is a critical factor in the effective management of chronic illness. When medication regimens are managed on behalf of an older care recipient, especially those with numerous medications for a variety of conditions, the caregiving task is even more complex. Relying on family support is common for older Mexican Americans. Despite this, there is little known about how Mexican Americans are handling their caregiving duties at home. A non-experimental methodological design was used to assess the psychometric properties of the FCMAHS with Mexican Americans, chosen because they are a rapidly growing population in the US. A purposive sample of 239 Mexican American adult caregivers, recruited in Dallas and San Diego, completed a brief biographical survey and the version of the FCMAHS created for Mexican Americans, i.e., the FCMAHS-MA. Principal axis factoring with orthogonal rotation was used to extract six factors which accounted for 53% of the variance in total scores - initial information seeking, safety issues, advanced information acquisition, scheduling, daily routine and prescription filling. Reliability estimates for the factors (alpha) ranged from 0.70-0.90. Test-retest reliability across a three-week interval was r = 0.64. The FCMAHC-MA shows promise as a guide for future caregiving intervention studies on family medication management for older relatives; however, it would benefit from refinement in future studies. Understanding family caregivers' hassles with medication administration is important because these hassles can accumulate and lead to caregiver strain. Culturally relevant intervention depends on accurate measurement of the hassles experienced by these caregivers.

To describe clinical results of Ahmed glaucoma valve implantation in Mexican patients with neovascular glaucoma (NVG). We reviewed records of 60 eyes of 60 patients with NVG who underwent Ahmed valve implantation, with a follow-up period of 1 year. We identified successful and failed cases and compared baseline and follow-up characteristics to identify possible differences between both groups. We classified 36 eyes (60%) as successful and 24 (40%) as failed cases. We found a significant difference in success rate in patients who had a hypertensive phase at any time during the follow-up period (OR = 5.15, CI = 1.49-20.15, p = 0.004). Patients in the success group showed a statistically significant decrease in the number of glaucoma medications 1 year after surgery (p <0.0001). We found a statistically significant difference in success rate in patients who had preoperative best corrected visual acuity (BCVA) better than logmar 0.70 (odds ratio 4.31, CI = 1.1-19.3, p = 0.03086). A hypertensive postoperative phase and a preoperative BCVA worse or equal to 20/100 seem to be risk factors for Ahmed valve surgical failure in patients with NVG.

2009-05-01

This study examines the joint impact of psychological and structural factors on Mexican and Mexican American elders' sense of personal control over important aspects of their lives and health in Mexico and the United States. We employ the Mexican Health and Aging Study (MHAS) and the Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-EPESE) to explore patterns of association among structural factors, personal characteristics, indicators of material and physical vulnerability, and expressed locus of control. The results suggest that an older individual's sense of personal control over important aspects of his or her life, including health, reflects real material and social resources in addition to individual predispositions. In Mexico, only the most privileged segment of the population has health insurance, and coverage increases one's sense of personal control. In the United States, on the other hand, Medicare guarantees basic coverage to the vast majority of Mexican Americans over 65, reducing its impact on one's sense of control. Psychological characteristics affect older individuals' sense of personal control over aspects of their health, but the effects are mediated by the economic and health services context in which they are expressed.

To report a rare case of the coexistence of 2 spinocerebellar ataxia (SCA) mutations in a single patient. Case report. University hospital, Movement Disorders Center. A 54-year-old man of Mexican, American Indian, and French descent with an 11-year history of gait and limb ataxia. Findings of clinical examination, magnetic resonance imaging, and video electroencephalographic monitoring. Neurologic history revealed a gradually progressive gait and limb ataxia along with muscle cramps and sensory symptoms in his distal extremities; examination revealed executive dysfunction, dysarthria, ataxia, and sensory neuronopathy. Episodes of loss of awareness were reported, but electroencephalograms were negative. Brain imaging demonstrated severe cerebellar and brainstem atrophy. Genetic evaluation of the case revealed mutations in both the SCA2 and SCA10 genes. Our patient has a unique combination of genetic mutations for 2 different SCAs, types 2 and 10, which to our knowledge, has not been previously reported. His clinical phenotype is largely consistent with SCA2, but his possible seizures and Mexican heritage suggest influences of SCA10.

Objectives Language brokering occurs frequently in immigrant families and can have significant implications for the well-being of family members involved. The present study aimed to develop and validate a measure that can be used to assess multiple dimensions of subjective language brokering experiences among Mexican American adolescents. Methods Participants were 557 adolescent language brokers (54.2% female, Mage.wave1 =12.96, SD=.94) in Mexican American families. Results Using exploratory and confirmatory factor analyses, we were able to identify seven reliable subscales of language brokering: linguistic benefits, socio-emotional benefits, efficacy, positive parent-child relationships, parental dependence, negative feelings, and centrality. Tests of factorial invariance show that these subscales demonstrate, at minimum, partial strict invariance across time and across experiences of translating for mothers and fathers, and in most cases, also across adolescent gender, nativity, and translation frequency. Thus, in general, the means of the subscales and the relations among the subscales with other variables can be compared across these different occasions and groups. Tests of criterion-related validity demonstrated that these subscales correlated, concurrently and longitudinally, with parental warmth and hostility, parent-child alienation, adolescent family obligation, depressive symptoms, resilience, and life meaning. Conclusions This reliable and valid subjective language brokering experiences scale will be helpful for gaining a better understanding of adolescents’ language brokering experiences with their mothers and fathers, and how such experiences may influence their development.

KiSS1 is a metastasis suppressor gene associated with inhibition of cellular chemotaxis and invasion attenuating the metastasis in melanoma and breast cancer cell lines. Along the KiSS-1 gene at least 294 SNPs have been described; however the association of these polymorphisms as genetic markers for metastasis in breast cancer studies has not been investigated. Here we describe two simple PCR-RFLPs protocols to identify the rs5780218 (9DelT) and the rs12998 (E20K) KiSS1 polymorphisms and the allelic, genotypic, and haplotypic frequencies in Mexican general population (GP) and patients with benign breast disease (BBD) or breast cancer (BC). The rs5780218 polymorphism was individually associated with breast cancer (P = 0.0332) and the rs12998 polymorphism shows statistically significant differences when GP versus case (BC and BBD) groups were compared (P < 0.0001). The H1 Haplotype (G/-) occurred more frequently in BC group (0.4256) whereas H2 haplotype (G/T) was the most prevalent in BBD group (0.4674). Our data indicated that the rs5780218 polymorphism individually confers susceptibility for development of breast cancer in Mexican population and a possible role as a genetic marker in breast cancer metastasis for H1 haplotype (Wt/variant) in KiSS1 gene must be analyzed in other populations.

Background. Leprosy is a chronic infectious disease caused by the intracellular acid-fast bacilli Mycobacterium leprae; it has been determined that genetic factors of the host play an important role in the disease susceptibility. Thus, in this case-control study, we evaluated the possible association between the IL-17A G-197A (rs227593) and IL-17F A7488G (His161Arg, rs763780) gene SNPs and susceptibility to leprosy disease in Mexican population. Methods. Seventy-five leprosy patients and sixty-nine control subjects were included. Both SNPs were genotyped with the polymerase chain reaction-restriction fragment length polymorphism technique. Results. We found nonsignificant differences in genotype and allele frequencies related to IL-17A G-197A (rs227593) and IL-17F A7488G (His161Arg, rs763780) gene SNPs in MB as well as subclinical forms of leprosy disease versus healthy individuals. Conclusions. Since the sample size is not large enough, it is difficult to sustain an association of susceptibility to leprosy with genotypes or allele frequencies of IL-17A G-197A (rs227593) and IL-17F A7488G (His161Arg, rs763780), suggesting that IL-17 polymorphisms have no significant role in the genetic susceptibility to development of this disease in the Mexican Mestizo population.

Carrillo, H

This paper analyzes how contemporary perceptions of male homosexuality are being shaped in Mexico. Ethnographic analysis included four short case studies from 64 mostly middle class individuals for two years in Guadalajara City. Mexican sexual culture is often portrayed traditionally as grounded in values inherent in machismo and influenced by Catholicism. There is a contrast between these traditional interpretations of roles and sexual identities in Mexico and the identities that are being adopted by many contemporary Mexican homosexual men. The homosexual men were categorizable in terms of 1) those who dominated in the sexual relationship and who were capable of maintaining a nonstigmatized identity as regular men, 2) those who assumed a feminine role and were penetrated and who were stigmatized for their effeminate demeanor, and 3) a minority of men who assumed both roles and who were termed "anally active and passive". The study revealed that middle-class homosexuals established networks in which individuals, supported by their friends, acquired the strength to effect personal changes along with other larger cultural changes. Thus, individual actions are beginning to have a collective effect on the society at large.

Diabetes Mellitus type 2 (DM2) is a group of metabolic disorders characterized by defective insulin action or secretion or both with a 10.6% incidence in Mexican Mestizo population, DM2 is also classified within the localized misfolding diseases due to the amyloid pancreatic deposits found in 90% of the DM2 necropsies. The pancreatic amyloid main component is a protein known as human islet amyloid polypeptide (hIAPP) or amylin, the most common mutation is the S20G in Asian population with a polymorphic frequency in DM2 Asian patients. The aim of this study was to search this mutation in Mexican Mestizo general population (104) and DM2 patients (100). This is the first molecular study of hIAPP gene in Mexican population and in which we developed an alternative more effective antisense primer for the analysis of the NFGAILSS region in hIAPP exon 3 critical for the amyloid beta structure formation. We did not find the mutation in any of the 204 analyzed samples, thus the findings show that S20G is not a common mutation in Mexican Mestizo population.

The objective of the work reported in this paper is to assess test-retest reliability of Yale Physical Activity Survey Total Time, Estimated Energy Expenditure, Activity Dimension Indices, and Activities Check-list in older Mexican American men and women. A convenience-based healthy sample of 49 (42 women and 7 men) older Mexican American adults recruited from senior recreation centers aged 68 to 80 years volunteered to participate in this pilot study. Forty-nine older Mexican American adults filled out the Yale Physical Activity Survey for this study. Fifteen (12 women and 3 men) of the 49 volunteers responded twice to the Yale Physical Activity Survey after a 2-week period, and helped assess the test-retest reliability of the Yale Physical Activity Survey. Results indicate that based on a 2-week test-retest administration, the Yale Physical Activity Survey was found to have moderate (rhoI= .424, p < .05) to good reliability (rs = .789, p < .01) for physical activity assessment in older Mexican American adults who responded.

Objectives. We assessed whether the few findings to date suggesting weak relationships between education and health-related variables among Hispanics are indicative of a more widespread pattern. Methods. We used logistic regression models to examine education differentials (i.e., education gradients) in health behaviors and outcomes among White and Mexican-origin adults, adolescents, and infants. We gathered information from 3 data sets: the Los Angeles Family and Neighborhood Survey, the Fragile Families and Child Wellbeing Study, and the National Health Interview Survey. Results. In contrast with patterns for Whites, education was weakly associated or not associated with numerous health-related variables among the US Mexican-origin population. Among adults, Mexican immigrants were especially likely to have weaker education gradients than Whites. Conclusions. The weak relationships between education and health observed among individuals of Mexican origin may have been the result of several complex mechanisms: social gradients in health in Mexico that differ from those in the United States, selective immigration according to health and socioeconomic status, and particular patterns of integration of Mexican immigrants into US society.

This study investigated whether and how different patterns of group exposure within residential contexts (i.e., living in a Mexican immigrant enclave, a Mexican ethnic enclave, a pan-Hispanic enclave, or a non-Hispanic white neighborhood) are associated with smoking during pregnancy among Mexican-origin mothers. Using a hierarchical linear modeling approach, we found that Mexican-origin mothers' residential contexts are important for understanding their smoking during pregnancy. Residence in an ethnic enclave is associated with decreased odds of smoking during pregnancy, while residence in a non-Hispanic white neighborhood is associated with increased odds of smoking during pregnancy, above and beyond the mothers' individual characteristics. The magnitude of the associations between residence in an ethnic enclave and smoking during pregnancy is similar across the different types of ethnic enclaves examined. The important roles of inter- and intra-group exposures suggests that in order to help Mexican-origin women, policy makers should more carefully design place-based programs and interventions that target geographic areas and the specific types of residential contexts in which women are at greater risk.

Mexican forest fires and their decadal variations

A high forest fire season of two to three years is regularly observed each decade in Mexican forests. This seems to be related to the presence of the El Niño phenomenon and to the amount of total solar irradiance. In this study, the results of a multi-cross wavelet analysis are reported based on the occurrence of Mexican forest fires, El Niño and the total solar irradiance for the period 1970-2014. The analysis shows that Mexican forest fires and the strongest El Niño phenomena occur mostly around the minima of the solar cycle. This suggests that the total solar irradiance minima provide the appropriate climatological conditions for the occurrence of these forest fires. The next high season for Mexican forest fires could start in the next solar minimum, which will take place between the years 2017 and 2019. A complementary space analysis based on MODIS active fire data for Mexican forest fires from 2005 to 2014 shows that most of these fires occur in cedar and pine forests, on savannas and pasturelands, and in the central jungles of the Atlantic and Pacific coasts.

We study the factors associated with food insecurity and participation in the Supplemental Nutrition Assistance Program (SNAP) in Mexican immigrant families in the US. Estimates from analyses that control for a rich set of economic, demographic, and geographic variables show that children in Mexican immigrant families are more likely to be food insecure than children in native families, but are less likely to participate in SNAP. Further, more vulnerable groups such as the first-generation Mexican immigrant families, families in the US for less than 5 years, and families with non-citizen children – that are at a higher risk of food insecurity are the least likely to participate in SNAP. Our analysis suggests that the US Department of Agriculture outreach initiative and SNAP expansion under the American Recovery and Reinvestment Act increased SNAP participation of the mixed-status Mexican families. We do not find any evidence that the outreach and ARRA expansion increased SNAP receipt among Mexican immigrant families with only non-citizen members who are likely to be undocumented.

Empirical research on biculturalism is limited, in part because of the lack of quality measures of biculturalism. The currently available measures have limitations due to scoring procedures and sampling of only a narrow range of behaviors and attitudes. We present a measure of biculturalism that captures a broader range of the bicultural experience and uses a scoring system that better represents the wide ranging levels of biculturalism that exist in the diverse population of Mexican American adolescents, mothers, and fathers born either in Mexico or the United States. The Mexican American Biculturalism Scale (MABS; 27 items) includes 3 subscales: bicultural comfort (9 items), bicultural facility (9 items), and bicultural advantages (9 items). We report on the reliability and construct validity of test scores, and confirmatory factor analyses findings for a diverse sample of 316 Mexican American families from a large southwestern metropolitan city. The MABS is available both in English and Spanish (see Appendix). The use of the scale has implications for future research studying how biculturalism is related to psychological outcomes for Mexicans/Mexican Americans. PMID:24548151
