Mexican Americans of Los Angeles County, both those born in Mexico and in the United States, were at lower risk to all sites of cancer combined, than other whites. These Mexican Americans were at increased risk to some specific cancers, including those of the stomach, gallbladder, and cervix. For those tumors for which racial differences existed, clear migrant patterns were present.
Ability to take the perspective of another was studied among 97 5 to 6- and 7 to 9-year-old Anglo American and Mexican American boys and girls. These children were administered seven perceptual role-taking tasks and the Children's Embedded Figures Test of field-independence. Results indicated no significant cultural differences. Results were contrary to previous findings in three aspects: (a) children were able to take the role of another younger than originally theorized by Piaget; (b) role-taking and field-independence were not significantly related when age is controlled; and (c) low and inconsistent correlations among the visual perspective role-taking tasks indicate that visual perspective role-taking is not an established unidimensional construct.
The paradox of underutilization of mental health services by Mexican Americans is critically examined. It is argued that Mexican Americans live under high levels of psychological and environmental stress that would ordinarily lead to mental health problems and an increased utilization of mental health services. A number of barriers to the use of mental health services by Mexican Americans are examined. Included among these barriers are such factors as the relationship between social class and treatment offered, stereotypes concerning Mexican American folk psychiatry, limitations imposed by language differences, and the effects of stereotypes between Anglo Americans and Mexican Americans. Paradoxical findings in some studies which show a positive perception of mental health services by Mexican Americans are seen to further underscore the need for more research on the Mexican American's position. Stereotypes and generalizations about Spanish-speaking and bilingual Mexican American's approaches to psychotherapy are challenged in the light of recent empirical findings. Recommendations for future research directions and for improving the delivery of mental health services are presented.
A drug usage study of students from a predominately Mexican-American population was conducted by comparing anonymously self-reported attitudinal and behavioral aspects of Mexican-American drug users and nonusers. Findings suggest M-A drug users and nonusers differ significantly in attitudes toward drug use and social behaviors, and users tend to be multiple drug users.
Pizzas, Mexican-American style foods, and submarine sandwiches were analyzed for proximate and mineral composition, and the nutrients compared with the Recommended Dietary Allowances for teen-agers. Fast foods can be a source of considerable nutrition. More nutritional analyses of fast foods are warranted and should be encouraged.
A number of reports indicate that Mexican-Americans have a lower prevalence of mental health service usage than other ethnic groups. Although a number of factors have been proposed to account for their underutilization, none of the factors have been adequately supported by existing research. Variables associated with the responsiveness and quality of mental health services, particularly the availability of bilingual-bicultural staff, are advocated as the most relevant areas for future research.
This is a study of the ventilatory functions of 1,805 normal Mexican-American, white, and black students of six public schools in Houston, Texas, with ages ranging from 7 to 20. A roll-seal piston type spirometer was used. The best performed forced vital capacity curve of each student was selected by the computer program from which the following measurements were extracted: FVC, FEV1, FEV1/FVC ratio, PEFR, and MMEF. Each student also had the peak expiratory flow rate measured by the Wright peak flowmeter to establish normal values with this instrument. Significant differences of lung volume and flow rate exist among the three races, and between male and female subjects. Prediction equations and prediction curves for each race and sex are presented. The results of the present study are compared with those of previously published works.
This is an evaluation of an Alcohol Treatment Unit with a focus on a comparison of Mexican-American and Anglo-American outcomes. Social adjustment on a target cohort of 75 was measured on a standard rating instrument (SAI) 2 years after discharge from the hospital. The overall successfulness of the program was 39%; the validity of the Treatment Difficulty Scale (a composite index of anticipated treatment difficulty) was demonstrated for both ethnic groups and both first and second year outcome results; and the average stability of first year findings of SAI components as compared to second year results was shown to be 79%. Use of a standardized index of pretreatment patient characteristics was recommended to facilitate comparative program evaluation research.
To date, there is little information available on stroke risk factors in a major ethnic minority such as Mexican-Americans (M-A) in the USA. Forty-three M-A patients were admitted to The Methodist Hospital and Ben Taub General Hospital (Houston) for a 12-month period, with diagnosis of atherosclerotic stroke. Thrombosis was diagnosed in 31 patients (72%), embolism from atherosclerotic sources in seven (16.4%), and parenchymal hemorrhage in five (11.6%). Hypertension was a common risk factor in all groups, being higher in hemorrhage followed by thrombosis and embolism. Arteriosclerotic heart disease was a common risk to all stroke types. TIAs, hyperlipidemia, diabetes, associated atherosclerotic lesions, smoking, obesity, erythrocytosis and sedentary life were significantly associated with embolism; less so with thrombosis or hemorrhage. Gout was only associated with thrombosis. These results indicate similar risk factors for Anglo-saxons and M-A in the USA with some minor differences between the Mexican and the USA stroke series.
The present study assessed intellectual, academic, and emotional strengths and weaknesses for a group of Mexican-American children of migrant farm workers. In order to test the vulnerability hypothesis, the test profiles of these children were contrasted with those of two groups of black children with similar demographic makeup. The children of one group (Clinical Black) had been referred previously for a psychological consultation while the children of the other (Nonreferred Black) had not. Across dependent measures, between-groups contrasts tended to describe the scores of the Migrant children as similar to those of the Clinical Black children and significantly below those of the Nonreferred Black children. The findings suggested specific intellectual, academic, and emotional vulnerabilities of the Migrant children and demonstrated the need to develop ameliorative programs for these children.
The frequencies of 32 HLA antigens of the A and B series were determined in a previously unstudied population of Mexican-Americans in South Texas. The phenotype and gene frequencies for this group are presented and are contrasted with those determined in studies of Mexican/Mexican--American populations from two different locales. The statistically significant differences observed emphasize the need for indigenous controls when evaluating racially heterogeneous populations for disease-associated HLA antigens.
This paper reviews the relevant literature and discusses the nature of Chicano concerns in regard to the implementation of legislation mandating developmental assessment of poor children. An approach to providing screening and remedial services responsive to the needs of Mexican-Americans is outlined.

A study was undertaken to establish the normal values of peak expiratory flow rate using the WPFM in three ethnic groups. This report is based on the testing of 1,805 healthy students 7 to 20 years of age in the Houston public schools. Significant differences of WPFR are noted among the three races, and between boys and girls. Prediction equations and regression lines are presented for each sex/race group. The performance of the WPFM is compared with that of the spirometer.
