Decreasing rates of cervical cancer among American Indians and Hispanics in New Mexico (United States)

Minority women in New Mexico (United States)--including American Indian and Hispanic women--have shown disproportionately high incidence rates of invasive cervical cancer during the 1960s and 1970s. Several public health programs in New Mexico were directed toward early detection of cervical cellular abnormalities, particularly targeting the state's minority women. To evaluate the effectiveness of these programs, we examined the New Mexico Surveillance, Epidemiology, and End Results (SEER) data collected from 1969-92, and calculated average annual, age-specific, and age-adjusted incidence rates by ethnic group (American Indian, Hispanic, and non-Hispanic White) for five-year time intervals. We also calculated age-adjusted mortality rates for cervical cancer in the same ethnic groups using state vital records. Age-adjusted incidence rates for invasive cervical cancer show substantial temporal decreases, especially for minority women in the state. The age-adjusted incidence rate decreased by 66 percent, from 30.3 to 10.3 per 100,000 for American Indian women, and by 61 percent, from 26.1 to 10.2 per 100,000 for Hispanic women. A stage shift to earlier stages of cervical neoplasia occurred over the study period, with a substantially higher proportion of in situ compared with invasive cancers diagnosed in the most recent cf the most remote time period. The ratio of incidence rates of in situ to invasive cancers changed dramatically for both American Indian and Hispanic women. Cervical cancer mortality rates decreased steadily among Hispanic women from 1958 to 1992; the decrease among American Indian women was less stable and fluctuated due to small numbers. Ongoing targeted screening programs should help to reduce cervical cancer incidence and mortality further in New Mexico.     

Trends in alcohol-related mortality among New Mexico's American Indians, Hispanics, and non-Hispanic whites

Reduction of alcohol-related mortality is a national goal for health promotion and disease prevention. We conducted this analysis to determine whether trends in New Mexico's Hispanics, non-Hispanic Whites, and American Indians were consistent with national trends in alcohol-related mortality, and whether differences in drinking patterns could account for racial and ethnic differences in rates. Age-adjusted, race-specific, and ethnic-specific alcohol-related mortality rates and 95% confidence intervals were calculated for 5-year periods for 1958-1991 using New Mexico vital statistics data. We estimated the prevalence of acute and chronic at-risk drinking behaviors and abstinence from data collected by the Behavioral Risk Factor Surveillance System (BRFSS) for the period 1986-1992. We found that alcohol-related mortality rates varied substantially by race, ethnicity, sex, age, and calendar period. American Indians had the highest rates for both sexes. Rates increased sharply from the period 1958-1962 until the late 1970s and the early 1980s, and then began to decrease rapidly. However, during the most recent decade, the rates have followed contrasting trends in the three ethnic and racial groups. Although rates have continued to decline among non-Hispanic Whites, rates for Hispanics and American Indians have not declined, and still remain substantially higher than rates during the 1958-1962 period. Differences in at-risk drinking behaviors reported to the BRFSS do not explain the contrast in race-specific and ethnic-specific mortality rates. Although progress has been made in reducing national per capita alcohol consumption and alcohol-related mortality, certain high-risk racial and ethnic groups may not be sharing in the progress.     

Burden of disease in the aged, Mexico, 1994

OBJECTIVE: To estimate the disability adjusted life years lost (DALYs) in population over 60 years of age in Mexico during 1994. MATERIAL AND METHODS: Years of life lost due to premature mortality (YLL) and years lived with disability (YLD) were estimated for 108 diseases, both sexes, and 32 states of the Mexican Republic divided in rural and urban areas in the population over 60 years of age, using the methodology originally proposed by Murray and López adapted to specific local characteristics. The inputs used were: mortality statistics for 1994 (after corrections of under-registration and misclassification), statistics on incidence and prevalence from local epidemiological studies, national health surveys and estimates by the authors. RESULTS: During 1994 the Mexican population over 60 years of age lost 1.8 million DALYs, 59% of which were YLL while 41% were YLD. Most of the burden of disease is due to noncommunicable diseases. The principal health needs of the elderly in Mexico can be divided in two groups: a) those that traditionally are frequent in this age group, such as ischaemic heart disease, diabetes, stroke and b) disabling diseases such as dementia, falls and arthritis as the most important. CONCLUSIONS: The use of composite indicators such as DALYs to assess health needs in older adult can help decision-makers and planners to incorporate disabling and lethal diseases within the list of priority needs, thereby achieving greater equity in the assignment of resources to different health care, prevention and rehabilitation programs.

Low prevalence of HTLV-II in Mayan Indians in the Yucatan Peninsula, Mexico

Infection with HTLV-II is endemic in Amerindians, with prevalence ranging from 0.89% - 33%. To determine the prevalence of HTLV-II among indigenous Mayans in the Yucatan Peninsula of Mexico, 440 indigenous Mayans were recruited, all native to and residents of one of six Mayan communities in the Yucatan Peninsula, (Xohuayan n=144, Yaxachen n=101, Kanxoc n=84, Xocen n=40, Nabalan n=46 and X'calot n=25) between May, 1992 and June, 1993. All of the above are pre-Hispanic settlements located in tropical forest with no immigrations for over 50 years. Of the 440 indigenous Mayans, only one woman from the X'calot tribe (0.23%) was shown to be infected with HTLV-II. A high percentage of indeterminate results was found (22/439, 5%), three of which were accounted for by the husband and two children of the positive female case. PCR analysis followed by specific restriction digestion demonstrated the virus to be of the HTLV-IIb subtype, similar to that described in the Guaymi Indians from Panama. The presence of HTLV-II in the Mayan ethnos, and in other Amerindian populations supports the idea that HTLV-II is an ancestral virus in America and that it has been sustained in "closed" communities.     

A review of induced abortion rates in England and Wales, 1969-1994

This study examines trends in induced abortion rates in England and Wales, from 1969 to 1994. A comparison of the trends between the different age groups shows contrasting changes and interesting features. The only age group to show a continuous increase since 1969 has been females aged 11 to 14 years. This may be due to birth cohort effect, as younger women begin sexual activity in a social environment of higher risk than previous cohorts. These considerations have important implications for the organisation of preventive services particularly health education. In spite of the availability of improved and better contraceptive services and sex education, the cohort analysis suggests that induced abortion rates in each successive cohort was higher than the preceding cohort.     

Bicycle helmet use among American children, 1994

The authors tested preoperatively and postoperatively for binocularity in a series of 29 adults who underwent surgery for long-standing concomitant strabismus. The authors used Bagolini lenses, troposcope and Worth's lights as the tests for binocularity. The patients in whom the postoperative deviation was greater than 10 prism diopters from orthotropia were excluded. Binocularity was not find at any patient before surgery. The authors made a finding of binocularity after strabismus surgery in 14% of patients, in spite of satisfactory parallel ocular alignment in 52% of patients. The results of development of binocularity after strabismus surgery in adults were not as good in this series as the other authors found.     

Cultural considerations when providing rehabilitation services to American Indians.

American Indians make up a small percentage of the U.S. population but reside in all states and territories and in all major cities. It is critical for rehabilitation psychologists to have an understanding of the unique cultural and ethnic issues associated with service provision to American Indian clientele. Considerations to be taken into account when providing culturally competent care to American Indians include general knowledge about sociopolitical history and current demographics, acculturation and racial identity, important health issues, and beliefs about health and illness. This article provides a brief introduction to facilitate more effective and culturally appropriate rehabilitation and health care to patients of American Indian heritage.

Prostate cancer in the African American: is this a different disease?

Reactive oxygen species such as superoxides, hydrogen peroxide (H2O2) and hydroxyl radicals have been suggested to be involved in the catalytic action of nitric oxide synthase (NOS) to produce NO from L-arginine. An examination was conducted on the effects of oxygen radical scavengers and oxygen radical-generating systems on the activity of neuronal NOS and guanylate cyclase (GC) in rat brains and NOS from the activated murine macrophage cell line J774. Catalase and superoxide dismutase (SOD) showed no significant effects on NOS or GC activity. Nitroblue tetrazolium (NBT, known as a superoxide radical scavenger) and peroxidase (POD) inhibited NOS, but their inhibitory actions were removed by increasing the concentration of arginine or NADPH respectively, in the reaction mixture. NOS and NO-dependent GC were inactivated by ascorbate/FeSO4 (a metal-catalyzed oxidation system), 2'2'-azobis-amidinopropane (a peroxy radical producer), and xanthine/xanthine oxidase (a superoxide generating system). The effects of oxygen radicals or antioxidants on the two isoforms of NOS were almost similar. However, H2O2 activated GC in a dose-dependent manner from 100 microM to 1 mM without significant effects on NOS. H2O2-induced GC activation was blocked by catalase. These results suggested that oxygen radicals inhibited NOS and GC, but H2O2 could activate GC directly.     

The incidence of systemic lupus erythematosus in North American Indians

The annual incidence (AI) of systemic lupus erythematosus (SLE) was determined in 75 highly inbred North American Indian tribes, a total of approximately 800,000 people, during the fiscal years 1971-1975. Seventy-two of the Indian tribes had an AI of SLE which was of similar magnitude to previously published studies from Sweden, Rochester (Minn.), Alabama, New York City, and San Francisco. However, Three tribes, the Crow, Arapahoe, and Sioux Indians, had a markedly elevated AI of SLE. These three tribes share common historical, geographic, and cultural characteristics. Further, they all reside in the northern half of the United States, in states that do not receive intense sun exposure, thereby eliminating photosensitivity as a major determinant of this increased prevalence. Finally, the AI of SLE in the Sioux Indians was highest for "full-blooded" members and lowest for genetic admixtures.     

An interpersonal analysis of affinity, clarification, and helpful responses with American Indians.

The interpersonal impact of counselor affinity, clarification, and helpful verbal responses used in the initial stages of counseling American Indian clients was examined. In Phase 1 of the study, a panel of 10 practicing counselors provided intent ratings for each type of response; 82 psychology students generated counselor statements in response to written counseling vignettes and rated their intent in providing each response. In Phase 2, 43 American Indian students assumed the role of a client and judged the interpersonal impact of each type of counselor verbal intervention using the Impact Message Inventory. The results with respect to Affinity and Clarification conditions revealed a reaction pattern of friendly submissiveness and supported the interpersonal principle of complementarity. More complex, uncomplementary reactions associated with hostile dominance were evoked by the Helpful condition. Implications of these findings and the utility of the interpersonal paradigm for cross-cultural counseling research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Obstacles for rural American Indians seeking alcohol, drug, or mental health treatment.

The purpose of this study was to identify factors associated with 4 clusters of obstacles (self-reliance, privacy issues, quality of care, and communication and trust) to mental health and substance abuse treatment in 3 treatment sectors for residents of 3 reservations in the United States. Participants (N = 3,084) disclosed whether they had sought treatment for emotional, drug, or alcohol problems in the past year and, if so, whether they had faced obstacles in obtaining care from Indian Health Services, tribal services, and other public or private systems. Correlates of these obstacles included negative social support, instrumental social support, utility of counselors, utility of family doctors, treatment sector, treatment type, diagnosis of an anxiety disorder, and tribe.

Evaluating cluster alarms: a space-time scan statistic and brain cancer in Los Alamos, New Mexico

OBJECTIVES: This article presents a space-time scan statistic, useful for evaluating space-time cluster alarms, and illustrates the method on a recent brain cancer cluster alarms in Los Alamos, NM. METHODS: The space-time scan statistic accounts for the preselection bias and multiple testing inherent in a cluster alarm. Confounders and time trends can be adjusted for. RESULTS: The observed excess of brain cancer in Los Alamos was not statistically significant. CONCLUSIONS: The space-time scan statistic is useful as a screening tool for evaluating which cluster alarms merit further investigation and which clusters are probably chance occurrences.     

Cancer mortality in Italy, 1994, and an overview of trends from 1955 to 1994

BACKGROUND: Data and statistics are presented on cancer death certification in Italy, updating previous publications covering the period 1955-1993. METHODS: Data for 1994 and the quinquennium 1990-94 subdivided into 30 cancer sites are presented in 8 tables, including age- and sex-specific absolute and percentage frequencies of cancer deaths, and crude, age-specific and age-standardized rates, at all ages and truncated for the 35-64 year age group. Trends in age-standardized rates for major cancer sites are plotted from 1955 to 1994. RESULTS: The age-standardized (world standard) death certification rates from all neoplasms steadily declined from the peak of 199.2/100,000 males in 1988 to 186.3 in 1994, and in females from 102.5 in 1989 to 98.6 in 1994. Ever larger was the decline in truncated rates, for males from the peak of 275.1/100,000 in 1983 to 223.2 (-19%) in 1994, and for females from 151.6/100,000 in 1987 to 136.4 (-10%). A major component of the favourable cancer mortality trends in males was lung cancer (accounting for 31,000 deaths in both sexes combined in 1994), whose overall age-standardized rates declined from 60.3 in 1987-89 to 54.6/100,000 males in 1994 (-9%), and from the peak of 96.7 in 1983 at ages 35 to 64 to 72.7 in 1994 (-25%). In contrast, female lung cancer rates have remained stable from 1992 onwards, but have increased from 7.2 to 7.7 at all ages and from 10.6 to 11.0 at age 35-64 between 1985-89 and 1990-94. These different trends in the two sexes reflect the patterns and trends in smoking among Italian males and females. CONCLUSIONS: Cancer mortality trends in Italy over the period 1990-94 were relatively favourable, mainly reflecting the decline in lung cancer rates in males, together with the persistent declines in gastric cancer in both sexes and in cervix uteri for women. Continuous advancements were registered for neoplasms amenable to treatment, essentially testicular cancer, Hodgkin's disease and childhood leukaemias. The major unfavourable trends were observed for non Hodgkin's lymphomas, and require therefore further monitoring, besides a clearer understanding of their determinants. Italy maintains an intermediate level of cancer mortality on a European scale, suggesting that further progress is possible, mostly for tobacco-related neoplasms in males.

Childhood cancer incidence and trends in Minnesota, 1988-1994

Childhood cancer incidence patterns for Minnesota, obtained from the Minnesota Cancer Surveillance System, were compared with national rates as well as with historic data from eight Minnesota counties. In total, 1,140 neoplasms were diagnosed in children (ages 0 to 14) between 1988 and 1994. Leukemias were the most common diagnosis for boys (30.3%) and girls (29.6%), followed by central nervous system tumors. The average annual age-adjusted incidence rates for all cancer sites were 167.2 and 136.2 per million for boys and girls, respectively. These rates were somewhat higher than national rates. In particular, the incidence rate for astrocytoma in boys was significantly elevated. Childhood cancer incidence, particularly brain tumors, has increased in the eight-county region from 1969 to 1994. This analysis demonstrated the Minnesota's childhood cancer incidence patterns are similar to national patterns.
