Diabetes, gallbladder disease, obesity, and hypertension among Hispanics in New Mexico.

Because Hispanics in the Southwest are genetically admixed with American Indians, the hypothesis has been advanced that the excess occurrence of diabetes mellitus, obesity, and gallbladder disease in this ethnic group may be genetic in origin and results from genes derived from American Indians. This report describes the prevalence of these diseases in 1,175 adult Hispanic participants in a survey of a New Mexico community conducted in 1984-1985. At nearly all ages, the majority of subjects had a body mass index of 25 kg/m2 or greater, and a substantial proportion exceeded 30 kg/m2. The prevalence of obesity was much greater in these Hispanics than is shown in nationwide data for US whites. Diabetes mellitus was also reported more often by Hispanic subjects in this survey than by US whites nationwide. A report of gallbladder trouble or of gallbladder removal was common in both males and females; the prevalence of gallbladder removal was as high in this population as in Mexican Americans previously studied in Starr County, Texas. In spite of the high prevalence of obesity, hypertension was less frequent among the New Mexico Hispanics than is shown in nationwide data for US whites. These findings complement those of previous surveys in Texas, which have shown a notably high proportion of adults to be obese, to have non-insulin-dependent diabetes mellitus, and to have gallbladder disease. The similar epidemiology of these diseases in the Hispanics of New Mexico and the Mexican Americans of Texas supports the hypothesis that American Indian admixture underlies the development of these conditions in Hispanics throughout the Southwest.

Prevalence of antibodies to Toxoplasma gondii in wild and domestic animals of New Mexico, Arizona and Colorado.

Using the Sabin-Feldman dye test, sera from wild and domestic animals in New Mexico, Arizona and Colorado were tested for the prevalence of antibodies to Toxoplasma gondii. The prevalence of positive titers (greater than or equal to 1:8) in animals from these areas was: New Mexico (178 of 569, 31%), Arizona (11 of 56, 20%), and Colorado (2 of 7, 29%). The overall prevalence of antibodies to Toxoplasma was 30% (191 of 632). Nine of 17 fecal samples from wild zoo felines contained Toxoplasma-like oocysts which were inoculated per os and intraperitoneally into mice. Mice from six of these nine inoculations later showed positive dye test titers and tissues from five of these six groups had tissue cysts when examined histologically.

Tick (Acari) infestations of bats in New Mexico.

A total of 278 bats belonging to 16 species was examined for ticks from various sites in New Mexico from 1994 to 1998. Seven species of bats were parasitized by ticks: larvae of Ornithodoros kelleyi Cooley & Kohls, Ornithodoros rossi Kohls, Sonenshine & Clifford (Argasidae), or both. Both species of ticks are reported from New Mexico for the first time. Infestation prevalences for parasitized bats ranged from 2 to 25% on different host species for O. kelleyi and from 7 to 25% for O. rossi. The pallid bat, Antrozous pallidus, and the big brown bat. Eptesicus fuscus, were parasitized by both tick species. No distinct host specificity was noted for either tick species.

Attitudes of physicians practicing in New Mexico toward gay men and lesbians in the profession.

PURPOSE: To examine the attitudes of physicians practicing in New Mexico toward gay and lesbian medical students, house officers, and physician colleagues. METHOD: In May 1996, the authors mailed a questionnaire with demographic and attitude questions to 1,949 non-federally employed physicians practicing in New Mexico. The questionnaire consisted of questions dealing with medical school admission, residency training, and referrals to colleagues. The response rate was 53.6%. RESULTS: Of all the responding physicians, 4.3% would refuse medical school admission to applicants known to be gay or lesbian. Respondents were most opposed to gay and lesbian physicians' seeking residency training in obstetrics and gynecology (10.1%), and least opposed to their seeking residency training in radiology (4.3%). Disclosure of homosexual orientation would also threaten referrals to gay and lesbian obstetrician-gynecologists (11.4%) more than to gay or lesbian physicians in other specialties. CONCLUSION: Physicians' attitudes toward gay and lesbian medical students, house officers, and physician colleagues seem to have improved considerably from those reported previously in the literature. However, gay men and lesbians in medicine continue to face opposition in their medical training and in their pursuit of specialty practice.

Improving the health of Indian teenagers--a demonstration program in rural New Mexico.

The health status of Indian teenagers in the United States is below that of the general population. The usual barriers to the use of health care services that young people, including young Indians, encounter are compounded in rural areas by distance, isolation, and lack of appropriate services. To overcome these barriers in rural New Mexico, a public health demonstration project (a) established a single location where adolescents can receive multiple, integrated health care services free of charge; (b) set up the initial program of services at a rural school; (c) established links with existing agencies; and (d) incorporated community action toward creating change. The project began as a joint effort of three communities, the University of New Mexico (UNM), and the Albuquerque Area Indian Health Service (IHS) of the Public Health Service; a secondary level public school soon became a participant. The project is being replicated in two other communities that have formed separate partnerships with UNM and the area IHS; also the New Mexico Health and Environment Department has joined the effort in one community. Preliminary data suggest that the services are being used by a majority of the target population, with the proportions of boys and girls about equal.

The APO E4 allele and cognition in New Mexico Hispanic elderly.

OBJECTIVE: To determine if the apolipoprotein E E4 (APO E4) allele is associated with cognitive performance in New Mexico Hispanic elderly. METHOD: We performed a cross-sectional survey of 105 community volunteers, aged 60 years and older, born in New Mexico, with both parents of Hispanic descent. Subjects were excluded for medical conditions that could influence cognitive performance. We also performed a longitudinal analysis on 18 participants who were re-tested over a 3-year interval. The main outcome measures for both the cross-sectional and longitudinal analysis were scores on 5 cognitive tests comparing subjects with the E4 allele to those without the E4 allele. RESULTS: The mean age was 69 years, with a range of 60 to 91. For the cross-sectional analysis, there were no significant differences between the 2 groups on the cognitive tests, although subjects with an E4 allele did not perform as well on color trails A (P=.09). In the longitudinal analysis we found that the variability of cognitive test scores tended to be higher in the E4 group on most cognitive measures. The time needed to complete color trails A (indicating slower performance) was significantly greater (P<.05) in the E4 group. For the total recall portion of the Fuld Object Memory test, the E4 group did not perform as well on follow-up (P=.08). CONCLUSION: We found no significant cross-sectional association between the APO E4 allele and cognitive performance. In our longitudinal analysis, the time needed to complete color trails A was significantly greater in the E4 group, and the E4 group did not perform as well on total recall.

Childhood cancer epidemiology in New Mexico's American Indians, Hispanic whites, and non-Hispanic whites, 1970-82.

The statewide population-based New Mexico Tumor Registry identified 473 malignant tumors among children of ages 0-14 years, during the period 1970-82. There were 235 non-Hispanic whites (50%), 189 Hispanic whites (40%), 38 American Indians (8%), and 11 other nonwhites (2%). The average annual age-adjusted incidence rates per million for non-Hispanic whites were 138.6 for males and 108.3 for females; for Hispanic whites, the rates were 108.5 for males and 80.9 for females; for American Indians, the rates were 75.5 for males and 78.0 for females. The incidence rates for all sites of cancer combined were lower for Hispanics and American Indians than for New Mexico's non-Hispanic whites and U.S. whites. Leukemia was the most common cancer in all racial-ethnic groups. In comparison with U.S. whites, American Indians were at low risk for leukemias, lymphomas, central nervous system (CNS), sympathetic nervous system (SNS), and kidney tumors and were at high risk for retinoblastoma, bone, and sex organ tumors. Hispanics were at low risk for CNS, SNS, kidney, sex organ, and liver tumors. Hispanic and non-Hispanic white males both were at increased risk for melanoma.

Survival of American Indian and Hispanic cancer patients in New Mexico and Arizona, 1969-82.

Survival was examined by ethnic group for 31,465 incident cancer cases diagnosed from 1969 through 1982 in Hispanic and non-Hispanic whites residing in New Mexico and in American Indians residing in New Mexico and Arizona. In comparison with the 1- and 5-year survival rates following the diagnosis of cancer for non-Hispanic whites, those for American Indians were generally poorer and, to a lesser extent, those for Hispanics were also poorer. The American Indian and Hispanic patients tended to have more advanced disease at the time of diagnosis, although this pattern was not consistent across all sites. For many primary cancer sites, American Indian patients were less likely to receive treatment for their cancer than were non-Hispanic whites. Hispanics were also less likely to be treated for cancers of some sites, although the differences were not as large as for American Indians. However, after adjustment for stage and treatment, American Indians demonstrated significantly poorer survival than non-Hispanic whites for cancers of many sites. After adjustment for stage and treatment, survival in Hispanics was generally comparable to that in non-Hispanic whites.

Incidence of spontaneous subarachnoid hemorrhage among Hispanics and non-Hispanic whites in New Mexico.

BACKGROUND AND PURPOSE: There are differences in cerebrovascular disease incidence between racial and ethnic groups. Little is known about cerebrovascular disease among Hispanics living in the southwestern United States as compared to non-Hispanic whites. This is the first study which measures and compares the incidence of spontaneous subarachnoid hemorrhage (SAH) among Hispanics and non-Hispanic whites living in Bernalillo County, New Mexico. This information may help reduce the risk and incidence of SAH. METHODS: Medical records of all possible cases of spontaneous SAH occurring during a two-year period (January 1, 1993 to December 31, 1994) among residents of Bernalillo County, New Mexico, were reviewed in all local hospitals. Hospital records were identified by ICD-9-CM codes. Medical examiner records were also reviewed for additional SAH cases occurring during the same time period. The 1990 U.S. census provided the population base. RESULTS: There were 22 spontaneous SAHs among 267,965 non-Hispanic whites and 25 spontaneous SAHs among 178,310 Hispanics. Incidence of SAH increased with age in both groups. The age- and sex-adjusted total annual incidence of SAH per 100,000 people was 3.73 among non-Hispanic whites and 9.19 among Hispanics (relative risk for Hispanics 2.46, 95% confidence interval 1.37-4.43, P = 0.003). The incidence rates among men and women were not significantly different in either ethnic group. CONCLUSIONS: The incidence of SAH among Hispanic residents of Bernalillo County, New Mexico, is approximately two and a half times higher than that among non-Hispanic whites. This suggests a higher prevalence or a greater tendency to rupture of berry aneurysms among Hispanics as compared to non-Hispanic whites. The reasons for this difference require further investigation.

Changing trends in mortality among New Mexico's American Indians, 1958-1987.

Health care availability and living conditions have improved substantially for American Indians in New Mexico over the past quarter century. To investigate the impact of these changes on health statistics, we examined mortality data collected from 1958 to 1987 for American Indians in the state. We analysed the data for all causes of death combined and for specific causes, and compared these data with figures for nonHispanic whites in the state. Age-adjusted mortality rates were calculated for 5-year periods for each ethnic-gender group, using denominators from US Census reports. Mortality rates for all causes combined did not improve significantly for American Indian males from 1958 to 1987, although the rates for American Indian females showed an 8% decline. Infectious disease-related mortality rates for American Indians decreased dramatically over the 30-year study period; however, mortality rates for cancer and diabetes increased over the 30-year period. Mortality rates for injuries and alcoholism among American Indians increased greatly from 1958 to 1977 and then declined later in the study period, but they were consistently higher than rates for whites. The study indicates that several chronic diseases remain of major public health importance for New Mexico's American Indian population.

The costing out of operational expenses between the Veterans Administration and the Air Force at the New Mexico Regional Federal Medical Center.

The purpose of this pilot study was to identify the cost of providing care to Veterans Administration (VA) and Department of Defense (DOD) patients eligible for care in the Emergency Department of the New Mexico Regional Federal Medical Center in Albuquerque, New Mexico. Medical records for the Emergency Department (N = 456) were reviewed for individual medical supply item and medication usage. Cost data were then tabulated for each item and each group, respectively. The results indicated that the DOD and VA shared equally in the consumption of expendable medical supply and medication funds in the Emergency Department.

Health implications of radionuclide levels in cattle raised near U mining and milling facilities in Ambrosia Lake, New Mexico.

This study was conducted to determine radionuclide tissue levels in cattle raised near U mining and milling facilities. Ambrosia Lake, New Mexico, has been the site of extensive U mining for 30 y and contains several underground U mines, a processing mill, and two large U tailings piles. Ten cows were purchased from two grazing areas in Ambrosia Lake and ten control animals were purchased from Crownpoint, New Mexico. Muscle, liver, kidney, and bone tissue taken from these animals, and environmental samples, including water, grasses and soil collected from the animals' grazing areas, were analyzed for 238U, 234U, 230Th, 226Ra, 210Pb, and 210Po. Mean radionuclide levels in cattle tissue and environmental samples from Ambrosia Lake were higher in almost every comparison than those found in respective controls. Liver and kidney tissues were particularly elevated in 226Ra and 210Po. Radiation dose commitments from eating cattle tissue with these radionuclide concentrations were calculated. We concluded that the health risk to the public from eating exposed cattle is minimal, unless large amounts of this tissue, especially liver and kidney, are ingested.

Changes in nonmelanoma skin cancer incidence between 1977-1978 and 1998-1999 in Northcentral New Mexico.

Nonmelanoma skin cancer (NMSC) is a highly common form of malignant disease in light-skinned populations. In 1977-1978, the National Cancer Institute sponsored a population-based skin cancer survey that found marked geographic variability in the incidence of NMSC within the United States. Some of the highest rates were observed in the southwestern state of New Mexico within its non-Hispanic white population. We recently undertook a follow-up survey of NMSC in New Mexico and report here incidence rate data for non-Hispanic white residents of a three-county area in northcentral New Mexico for two 12-month time periods: June 1, 1977 to May 31, 1978 and July 1, 1998 to June 31, 1999. Our results show that incidence rates of basal cell carcinoma increased by 50% in males and 20% in females, whereas rates of squamous cell carcinoma roughly doubled in both males and females. Temporal analysis of rates according to major anatomical site showed the head and neck was consistently the most frequent site of occurrence, however, the greatest percentage increase in rates over time occurred at the upper and lower limbs. These findings are consistent with those reported for various other populations showing the incidence of NMSC has measurably increased since the 1970s.

Twenty-seven years of forensic anthropology casework in New Mexico.

A review of anthropological consult cases for the New Mexico Office of the Medical Investigator was conducted for the years 1974 through 2000. A total of 596 cases are summarized and information is presented on the sex and age of the individuals, season of recovery, depositional environment, body covering, time since death, perimortem trauma, postmortem animal activity, and skeletal element recovery. Results reveal a higher percentage of male victims (76%). No variation is seen in the seasonal distribution of cases. In cases with known time since death, 35% were recovered within one week while 30% had a postmortem interval exceeding one year. Depositional environments include surface (45%), burial (13%), and airplane crashes (9.5%). In 42% of the cases, no evidence of perimortem trauma was observed. Postmortem animal activity was noted in 46% of cases. Data presented in this study may prove useful in supporting expert witness testimony and generating future research models.

Quality of care in episodes of respiratory illness among Medicaid patients in New Mexico.

As part of ambulatory-care review, the New Mexico Experimental Medical Care Review Organization (EMCRO) developed medical guidelines for the use of injections and informed physicians about them through written communications and personal visits. After their adoption, the EMCRO denied payment for Medicaid claims not meeting the guidelines. To study the effect of these activities, we compared quality of care in entire episodes of respiratory infections before and after guidelines were promulgated. Quality as judged by minimal criteria for antibiotic use improved. Percentages of episodes with appropriate therapy rose from 36% to 42% for streptococcal sore throat, from 42% to 81% for bronchitis, and from 36% to 51% for acute upper respiratory infection. Quality improved most among physicians with the poorest records initially; "outliers" still gave inadequate care. Assessment of episodes of care derived from claims data thus appears to be a feasible and nonintrusive mechanism for detecting deficiencies in quality and evaluating quality-assurance activities.

Incidence of plague associated with increased winter-spring precipitation in New Mexico.

Plague occurs episodically in many parts of the world, and some outbreaks appear to be related to increased abundance of rodents and other mammals that serve as hosts for vector fleas. Climate dynamics may influence the abundance of both fleas and mammals, thereby having an indirect effect on human plague incidence. An understanding of the relationship between climate and plague could be useful in predicting periods of increased risk of plague transmission. In this study, we used correlation analyses of 215 human cases of plague in relation to precipitation records from 1948 to 1996 in areas of New Mexico with history of human plague cases (38 cities, towns, and villages). We conducted analyses using 3 spatial scales: global (El Niño-Southern Oscillation Indices [SOI]); regional (pooled state-wide precipitation averages); and local (precipitation data from weather stations near plague case sites). We found that human plague cases in New Mexico occurred more frequently following winter-spring periods (October to May) with above-average precipitation (mean plague years = 113% of normal rain/ snowfall), resulting in 60% more cases of plague in humans following wet versus dry winter-spring periods. However, we obtained significant results at local level only; regional state-wide precipitation averages and SOI values exhibited no significant correlations to incidence of human plague cases. These results are consistent with our hypothesis of a trophic cascade in which increased winter-spring precipitation enhances small mammal food resource productivity (plants and insects), leading to an increase in the abundance of plague hosts. In addition, moister climate conditions may act to promote flea survival and reproduction, also enhancing plague transmission. Finally, the result that the number of human plague cases in New Mexico was positively associated with higher than normal winter-spring precipitation at a local scale can be used by physicians and public health personnel to identify and predict periods of increased risk of plague transmission to humans.

Outcome of recruitment and report on participation rate in the New Mexico Elder Health Survey.

The purpose of this paper is to report on the outcome of recruitment and participation rate in the New Mexico Elder Health Survey. This survey is the first community based epidemiological survey to examine health and health related issues of elderly (65 years or older) Hispanics and non-Hispanic whites in Bernalillo County (Albuquerque), New Mexico. This survey was conducted from May 1993 to September 1995. Subjects (N=2200) were randomly selected from the list of 50,700 Medicare recipients residing in Bernalillo County and stratified by ethnicity and gender. Hispanics were identified using a computer program that selects Hispanic surname patterns and ethnicity was verified by self report. Subjects participated in a home interview, followed by an interview and examination in a senior health clinic. Use of the Medicare list resulted in 75.7% (N=1666) of subjects being contacted. Of the 1666 subjects available, 1130 (67.8%) completed a home interview and 883 (54%) completed the full examination. There were no significant differences in participation by ethnicity, but there were significant differences by gender, with women less likely to participate. The mean age of participants was 74 years, age range 65 to 100. Hispanic elderly demonstrated greater economic poverty and lower levels of formal education. Our survey results show that the elderly and Hispanic elderly can be successfully recruited to participate in a research study. This paper is the first to summarize the details of the survey design, present the results of recruitment and participation, and describe the survey participants.
