Cancer mortality among New Mexico's Hispanics, American Indians, and non-Hispanic Whites, 1958-1987.

BACKGROUND: Racial and ethnic differences in cancer incidence and mortality are well documented. New Mexico's ethnically and racially diverse population provides an opportunity to further examine ethnic and racial differences in cancer occurrence. PURPOSE: To address differences in cancer mortality among the state's Hispanics, American Indians, and non-Hispanic Whites, we examined mortality data collected from 1958 through 1987. METHODS: Sex and age-specific and age-adjusted cancer mortality rates were calculated for all sites and specific sites for American Indians, Hispanics, and non-Hispanic Whites. From 1958 through 1987, deaths due to malignant neoplasms were coded according to the International Classification of Diseases. The categories of malignant neoplasms investigated were chosen, in part, to minimize bias due to changes in disease classification. Ethnicity was assigned by the Bureau of Vital Statistics on the basis of information on death certificates. Denominators were derived from the censuses of 1960, 1970, 1980, and 1990. Age-standardized mortality rates were calculated for 5-year periods (1958-1962, 1963-1967, 1968-1972, 1973-1977, 1978-1982, and 1983-1987), with the 1970 U.S. population as the standard. We also examined age-specific rates by time period. RESULTS: Within each of New Mexico's ethnic groups, overall cancer mortality increased over the 30-year time span, and the cancer mortality rates were greater for males than for females. For most major cancer sites, mortality rates for New Mexico's non-Hispanic Whites were comparable with data for U.S. Whites. American Indians had the lowest rates for most sites, whereas cancer mortality rates for most sites among Hispanics were intermediate between the two other groups. However, Hispanics and American Indians had higher mortality rates for cancers of the gallbladder, cervix, and stomach compared with non-Hispanic Whites throughout most of the study period. Several other cancer sites showed major mortality rate differences among these racial and ethnic groups, including cancers of the colon, rectum, breast, bladder, lung, ovary, and uterus. We also observed strong temporal trends of increasing or decreasing mortality rates for several cancer sites. CONCLUSIONS: Race and ethnicity have been strong determinants of cancer mortality in New Mexico. Within the span of one generation, cancer mortality has changed substantially for some cancer sites in each of the population groups studied. IMPLICATIONS: These mortality data underscore the need for appropriately designed etiologic studies of cancer in diverse racial and ethnic groups. Such etiologic studies could provide new insights concerning risk factors for cancer and useful data for developing race- and ethnic-specific cancer control strategies.

Epidemiology of sarcopenia among the elderly in New Mexico.

Muscle mass decreases with age, leading to "sarcopenia," or low relative muscle mass, in elderly people. Sarcopenia is believed to be associated with metabolic, physiologic, and functional impairments and disability. Methods of estimating the prevalence of sarcopenia and its associated risks in elderly populations are lacking. Data from a population-based survey of 883 elderly Hispanic and non-Hispanic white men and women living in New Mexico (the New Mexico Elder Health Survey, 1993-1995) were analyzed to develop a method for estimating the prevalence of sarcopenia. An anthropometric equation for predicting appendicular skeletal muscle mass was developed from a random subsample (n = 199) of participants and was extended to the total sample. Sarcopenia was defined as appendicular skeletal muscle mass (kg)/height2 (m2) being less than two standard deviations below the mean of a young reference group. Prevalences increased from 13-24% in persons under 70 years of age to >50% in persons over 80 years of age, and were slightly greater in Hispanics than in non-Hispanic whites. Sarcopenia was significantly associated with self-reported physical disability in both men and women, independent of ethnicity, age, morbidity, obesity, income, and health behaviors. This study provides some of the first estimates of the extent of the public health problem posed by sarcopenia.

Tribal differences in diabetes: prevalence among American Indians in New Mexico.

The prevalence of diagnosed diabetes among American Indians in New Mexico with varied genetic and cultural backgrounds is reported. Utilizing community-based registries, the prevalence in persons ages 35 years and older ranged from 9.8 percent among Jicarilla Apache Indians to 28.2 percent among Zuni Indians. All rates were significantly higher than the U.S. rate of 5.3 percent for the same age group. In addition, in three of the five tribal groups examined, the rates of diagnosed diabetes in Indians less than 35 years of age (range from 0.5 percent to 1.3 percent) were significantly higher than the U.S. rate of 0.4 percent for the same age group. The prevalence rates of diagnosed diabetes found in this study of American Indians in New Mexico were intermediate between those for the United States as a whole and the Pima Indians of southern Arizona. Reasons for the variations and the relative contribution of obesity, fitness, or genetic risk in the development of diabetes need further study.

Safe at home? Domestic violence and other homicides among women in New Mexico.

STUDY OBJECTIVE: To define the contribution of domestic violence (DV) to homicides in women in New Mexico and to examine differences in ethnicity, mechanism, previous documented injuries, incidence of sexual assault, and use of alcohol or illicit drugs between DV- and non-DV-related homicides. METHODS: We carried out a retrospective analysis of reports of the state office of the medical investigator (OMI) reports from all female homicides from 1990 to 1993 in New Mexico. A homicide was defined as being related to DV if the perpetrator was a current or former male intimate partner. The chi-squared and Mann-Whitney tests were used to analyze data. RESULTS: The OMI investigated 134 homicides in women for an overall fatality rate of 4.3 per 100,000. A male intimate partner was the perpetrator in 62 cases (46%). The rate of DV homicide among American Indians (4.9 per 100,000) was significantly higher than that among Hispanics (1.7) and non-Hispanic whites (1.8)(RR=2.8; 95% confidence interval (CI), 1.5 to 5.1). Firearms were almost two times as likely to be used in DV homicides as in non-DV homicides (RR=1.8; 95% CI, 1.2 to 2.6). Evidence of old injuries was found more often in DV homicide cases (35.5%) than in non-DV cases (83%) (RR=4.3; 95% CI, 1.8 to 9.8). The presence of alcohol or other drugs was higher among non-DV homicide victims (69%) than DV homicide victims (54.3%) (P=.03). CONCLUSION: American Indian women are at particularly high risk of homicide, including DV homicide. Firearms were overrepresented in DV homicides, suggesting that removing firearms from the homes of previous DV perpetrators would be a useful public health strategy. Alcohol or illicit drugs were found in approximately two thirds of New Mexico women who were victims of homicide. The high prevalence of history of previous injuries among DV homicide victims indicates that early identification of DV victims in the emergency department and other health care settings is an important point of intervention.

Altitude and mortality from chronic obstructive lung disease in New Mexico.

This study tested the hypothesis that altitude increases mortality from chronic obstructive lung disease (COLD) in New Mexico. A death was attributed to COLD if it resulted from chronic bronchitis, emphysema, or chronic obstructive lung disease, according to the Eighth Revision International Classification of Diseases, Adapted for Use in the United States. New Mexico's average annual ethnic and sex-specific mortality rates from COLD were calculated using death certificate data for the period 1969 to 1977. Deaths were assigned to altitude groups according to the county of residence at the time of death. Mortality rates for whites exceeded nationwide rates at all altitudes. However, mortality rates showed no increase with altitude. In fact, mortality from COLD decreased significantly with altitude for non-Hispanic white (Anglo) males (P less than .02). Immigration of Anglos to the lower altitudes of New Mexico probably explains these results.

Critical elements in the design of culturally appropriate interventions intended to reduce health disparities: immunization rates among Hispanic seniors in New Mexico.

The importance of immunization in protecting seniors against influenza and pneumonia has long been recognized. Nevertheless, immunization rates among Medicare beneficiaries continue to fall short of what is both desirable and achievable. The problem is even more acute among certain racial and ethnic groups in the United States within which rates are below the rate for the country as a whole. This is true in New Mexico where 40 percent of the population is estimated to be Hispanic. As part of its work on behalf of the Centers for Medicare & Medicaid Services (CMS), the New Mexico Medical Review Association (NMMRA) undertook a project aimed both at reducing the disparities that exist in immunization status between the Hispanic and non-Hispanic population in the state and attempting to increase overall rates in the state for all groups. Developing interventions to reduce disparaties in immunization rates between Hispanic seniors and the rest of the senior population requires more than a straightforward review of the literature and must take into account not only the cultural differences that exist between Hispanics and non-Hispanics but, certainly, in the case of New Mexico, it must attempt to understand the richness and diversity that exists within the Hispanic communities across the state. To do otherwise runs the risk of designing interventions that are at best ineffective and at worst culturally insensitive and potentially damaging to future efforts to improve health status. This article describes the process undertaken by NMMRA, a Medicare Quality Improvement Organization (QIO), to collect qualitative data from three culturally different groups of Hispanics in New Mexico. The data are used to design interventions that will increase immunization rates for all Hispanics in New Mexico.

Differences in cancer incidence among Indians in Alaska and New Mexico and U.S. Whites, 1993-2002.

Cancer incidence for American Indians and Alaska Natives is typically reported as a single rate for all U.S. indigenous populations combined. Previously reported combined rates suggest that American Indians and Alaska Natives have lower cancer incidence rates compared with the U.S. population. Alaska Native people comprise three major ethnic groups: Eskimo, Indian, and Aleut people. We examined cancer incidence from only Alaska Indians and compared incidence rates with an American Indian population living in New Mexico. These data indicate striking differences in cancer patterns between two American Indian populations. Cancer data for the years 1993 to 2002 for American Indians of New Mexico and U.S. Whites are from the National Cancer Institute Surveillance, Epidemiology, and End Results Program Public-use data set. Data for Alaska Indians are from the Alaska Native Tumor Registry, which is also a Surveillance Epidemiology and End Results Program participant. Overall, cancer incidence rates for all sites combined in New Mexico Indian men and women were lower than U.S. White rates, whereas Alaska Indian men and women exceeded U.S. rates. In comparing Alaska and New Mexico Indians, we observed a 2.5-fold higher incidence of cancer among Alaska Indians. The largest differences between the two Indian populations were noted primarily in cancers associated with tobacco use, including cancers of the oral cavity/pharynx, esophagus (only in men), colon and rectum, pancreas, larynx (men), lung, prostate, and urinary bladder (men). Lung cancer rates in Alaska Indian men and women were 7 and 10 times those of New Mexico Indian men and women.

Prostate cancer mortality in Connecticut, Iowa and New Mexico African American men.

We sought to assess trends in prostate cancer incidence, treatment and mortality in African American men by means of analysis of prostate cancer data from three states, Connecticut, Iowa and New Mexico, all participants in the Surveillance, Epidemiology, and End Results (SEER) Program. Compared with levels before prostate specific antigen (PSA) testing, prostate cancer incidence increased in all three states after widespread testing. For men diagnosed with localized or regional prostate cancer, the respective increases in radical prostatectomy in Connecticut, Iowa, and New Mexico were 3.2, 2.3, and 4.9 times pre-test levels. Age-standardized mortality in Connecticut and Iowa increased slightly; in New Mexico the 104.7 deaths per 100,000 in 1979-1986, 62.1 in 1987-1990, dropped to 47.6 in 1991-1998, an amount of decline that was statistically significant. Introduction of PSA testing influenced early detection and treatment of prostate cancer in all three states. Although decline in prostate cancer mortality in New Mexico over time may be linked with use of the PSA test and definitive therapy, the relationship among these factors, and thus the proper treatment for the early stages of this condition, is unclear on the basis of these data.

Anopheles hermsi, probable vector of malaria in New Mexico.

Samples of Anopheles freeborni s.1. were collected from areas of New Mexico where malaria had once been common and sporozoites had been isolated from this species. Specimens were identified by analysis of polytene chromosome banding patterns and by specific rDNA fragments generated through the polymerase chain reaction. All samples collected in New Mexico were identified as An. hermsi, which was the probable vector of malaria in this region during the early 20th century.

The New Mexico Melanoma Registry. A model of a statewide cooperative program.

The prevalence of cutaneous melanoma is high among Anglo residents of New Mexico. In order to achieve consistency in diagnosis and pathologic staging, a melanoma registry was established in 1980 in conjunction with the University of New Mexico Cancer Center. The registry functions through pathology panel review of newly diagnosed melanomas combined with collection of clinical data. Reports are submitted gratis to contributing pathologists and dermatologists. The melanoma registry works closely with the population-based New Mexico Tumor Registry. Acceptance of the melanoma registry has been excellent. We believe that in excess of 90% of new melanoma cases in the state are sent spontaneously to the registry. During 1986 approximately 150 melanomas were reviewed together with 450 atypical, benign pigmented lesions such as dysplastic nevi. In addition to pathology consultations, the registry serves an educational function and has potential for a variety of epidemiologic studies.

New Mexico community voices: policy reform to reduce oral health disparities.

Using a socio-ecological framework to guide the initiative, New Mexico Community Voices developed, with state and local stakeholders, responsive oral health policies to address oral health disparities. Several policy objectives were achieved: increasing awareness of the public health importance of oral health; improving access to dental services for uninsured or underserved populations; enhancing dental services specialty care; and increasing sustainable oral health infrastructure through pipeline development of oral health providers to relieve service shortages and diversify the oral health workforce. Improving access to oral health and augmenting numbers of dental providers in rural areas were also successful. The governor has appointed the New Mexico Oral Health Advisory Council to address state oral health issues. The New Mexico partnerships have demonstrated how effective policy change can generate important incremental shifts in oral health care delivery and provide best practice models that diminish the oral health crisis faced by underserved populations.

Inhalant abuse and juvenile delinquency: a control study in Albuquerque, New Mexico.

This paper examines the relationship between inhalant abuse and delinquency among juveniles in Albuquerque, New Mexico. The arrest records of 100 juvenile delinquents identified as chronic inhalant abusers are compared with two control groups (N = 100 each) of other delinquents from Albuquerque. One control group was stratified on age, sex, and ethnicity, and the other was a simple random sample. The demographic characteristics of inhalant abusers indicated an overrepresentation of young, male Hispanics from large, poor, disrupted families where siblings were involved in both the abuse of inhalants and a variety of other delinquent activities. The inhalant abusers were much more likely to be arrested for virtually every type and category of delinquent activity. Specifically, inhalant abusers are considerably more criminal regarding total offenses committed, status offenses, crimes against property, crimes against persons, and criminal and violent offenses. Therefore, this study has indicated a strong relationship between inhalant abuse and juvenile delinquency.

Tinaminyssus juxtamelloi sp. n. (Acari: Dermanyssidae; Rhinonyssinae) from the nasal passages of the band-tailed pigeon, Columba fasciata, in New Mexico.

Tinaminyssus juxtamelloi sp. n. is described from the nasal passages of Columba fasciata in New Mexico. The new species is most similar to Tinaminyssus melloi (Castro) 1948 and T. turturi (Fain) 1962, but differs in (1) possessing only 5 pairs of ventral opisthosomal setae, (2) presence of 3 pairs of enlarged setae on the dorsal opisthosoma at the posterolateral margin of the podosomal plate (1 pair) and at the lateral margins of the opisthosomal plate (2 pairs), (3) elongate shape and larger size of the poststigmatic plates, and (4) chaetotaxy and solenidiotaxy of the legs, especially tarsus I with a cluster of 4 solenida and 1 club-shaped solenidion on the apex of the dorsum. The relationships of this with allied species of the genus Tinaminyssus from columbiform birds are briefly discussed.

Changing treatment of breast cancer in New Mexico from 1969 through 1985.

A review of information from the New Mexico Tumor Registry on women diagnosed as having primary breast cancer from 1969 through 1985 revealed temporal changes in the surgical treatment of this disease. After 1980 the percentage of women receiving breast-conserving surgery for local-stage disease increased from 6% to 25%. Most surgeons performing operations for breast cancer had not performed a breast-conserving operation before 1981 but had used this procedure at least once in the period from 1981 through 1985. Women younger than 50 years or older than 80 years were most likely to undergo this procedure. In that period, radiotherapy after breast-conserving surgery could not be documented for 26% of the women 65 years old or younger or for 56% of the women aged 65 years or older. Thus, there has been a marked shift in New Mexico in the surgical approach to local-stage breast cancer in the 1980s. This shift involved most surgeons treating the disease and included women of all age groups. The apparent lack of adjuvant radiotherapy in some women receiving conservative surgeries may prove to be a deleterious consequence of this change in surgical management.

Trends in prostate cancer incidence and mortality in New Mexico are consistent with an increase in effective screening.

The increasing occurrence of prostate cancer in the United States has led to recommendations for routine prostate cancer screening in men aged 50 years and older. Although present methods of prostate cancer screening have not been shown to reduce mortality, screening using digital rectal examination or prostate-specific antigen does detect tumors at earlier stages. To assess whether trends in incidence and mortality rates are consistent with an increase in effective screening in New Mexico, we examined prostate cancer incidence rates calculated from data collected by the New Mexico Tumor Registry for the years 1969-1991, and mortality rates calculated from data collected by the New Mexico Bureau of Vital Statistics for the years 1958-1991. Population-based measures of prostate cancer screening frequency in New Mexico are not available for the period of this study; however, the proportion of prostate cancers detected by screening, as documented by a review of records from a random sample of prostate cancer cases, increased 3-fold, from 13% during the 1969-1972 period to 41% in the 1988-1991 period. During the period of study, age-adjusted incidence rates increased from 66.3 to 122.3/100,000 men. Stage migration from distant to earlier stages was apparent in the increase in the proportion of early stage cancers from 77.5 to 85.5%, and the decrease of distant stage cancers from 21.2 to 9.8%. Stage-specific incidence rates increased for local (87.3%) and regional stage cancers (283.0%), and decreased for distant stage cancers (16.0%).(ABSTRACT TRUNCATED AT 250 WORDS)

Ethnic differences in mortality from acute rheumatic fever and chronic rheumatic heart disease in New Mexico, 1958-1982.

To examine time trends and differences in mortality rates from acute rheumatic fever and chronic rheumatic heart disease in New Mexico's Hispanic, American Indian, and non-Hispanic white populations, we analyzed vital records data for 1958 through 1982. Age-adjusted mortality rates for acute rheumatic fever were low and showed no consistent temporal trends among the three ethnic groups over the study period. Age-adjusted and age-specific mortality rates for chronic rheumatic heart disease in Hispanic and non-Hispanic whites decreased over the 25-year period, although rates were higher among Hispanics than among non-Hispanics during most of the time period. In American Indians, age-adjusted mortality rates for chronic rheumatic heart disease increased between 1968 and 1977 to twice the non-Indian mortality rates during the same period. Despite this increase in mortality from chronic rheumatic heart disease among New Mexico's American Indians from 1968 to 1977, the New Mexico data generally reflect national trends of decreasing mortality from chronic rheumatic heart disease.

Fostering the health of communities: a unifying mission for the University of New Mexico Health Sciences Center.

Fostering the health of communities can serve as a unifying mission of the academic health center (AHC), which can set the AHC apart from other health providers in the community. To achieve this mission, the University of New Mexico's AHC is increasingly focusing education, research, and service upon the identified health and service needs of communities in its state. Since major health problems in our society have social, behavioral, and economic roots, New Mexico's AHC has tapped into the broad expertise of its different components as well as that of its state and community partners to adequately address health problems in the community. Its hospitals offer financing and management resources, its colleges offer innovative approaches to community-based education, and the state department of health offers expertise in health policy development. To adequately respond to the complexity of community health needs, the different colleges and departments at New Mexico's AHC are increasingly merging into integrated governance units. Measures of community outreach success include evidence of strengthened community development, increased health care access, and improved indices of community health. New Mexico's AHC formed an interdisciplinary rural outreach task force, which has demonstrated its ability to form partnerships with state and local agencies and to mobilize institutional resources in education, research, and service from the AHC's different departments, colleges, and hospitals to respond promptly to unique community health needs. Evidence shows that such an integrated, coordinated AHC intervention can generate strong and lasting AHC-community alliances, improve the quality and economic viability of community health systems, and enhance the financial resources of the AHC.

Malignant melanoma of the skin in New Mexico 1969-1977.

We assessed the occurrence of malignant melanoma of the skin in New Mexico from 1969-1977. Incidence data, collected by the New Mexico Tumor Registry, were supplemented with mortality data supplied by the State Bureau of Vital Statistics. These data were analyzed for variation by site, sex, and ethnic group. Malignant melanoma occurrence varied with ethnicity. Incidence rates for non-Hispanic whites (Anglos) exceeded comparison US rates, and were approximately six times higher than for other ethnic groups. Annual incidence rates for Hispanics, American Indians, and blacks of both sexes ranged from 0.0-1.8 cases per 100,000. As anticipated from other studies, the lower extremities were the most common site in Anglo women, and the trunk was the most common site in Anglo men. In contrast, the trunk was the most common site for both Hispanic men and women. A statistically significant trend of increasing incidence was demonstrated only for the Anglo women. Mortality rates varied widely during the study period and did not correlate with incidence rates.
