Abstract
BACKGROUND Little research has been conducted that integrates, in one explanatory model, the multitude of factors potentially leading to disparities among Latino children. PURPOSE A longitudinal, observational study tested an explanatory model for disparities in asthma control between Mexican and Puerto Rican children with persistent asthma requiring daily controller medication use. METHODS Mexican and Puerto Rican children aged 5-12 years (n = 267) and their caregivers (n = 267) were enrolled and completed interviews and child spirometry at baseline and 3, 6, 9, and 12 months postenrollment. A 12 month retrospective children's medical record review was completed. Participants were recruited from two school-based health clinics and the Breathmobile in Phoenix, AZ, and two inner-city hospital asthma clinics in the Bronx, NY. RESULTS Statistically significant differences in the social/contextual predictors of asthma illness representations (IRs) were noted between Mexican and Puerto Rican caregivers. The structural equation model results revealed differences in asthma control over time by ethnicity. This model accounted for 40%-48% of the variance in asthma control test scores over 12 months. Caregivers' IRs aligned with the professional model of asthma management were associated with better children's asthma control across 1 year. These results also supported the theoretical notion that IRs change over time impacting caregivers' treatment decisions and children's asthma control. CONCLUSIONS These findings extend a previous cross-sectional model test using a more comprehensive model and longitudinal data and highlight the importance of considering within-group differences for diagnosis and treatment of children coming from the vastly heterogeneous Latino umbrella group. TRIAL REGISTRATION Trial number NCT01099800.

Abstract
Physical activity (PA) may improve quality of life and survival among cancer survivors; however, little is known about Navajo cancer survivor PA. We evaluated Navajo cancer survivor PA habits, barriers, and preferences through focus groups and interviews (n = 32). Transcripts were coded in NVivo and major themes summarized by consensus. Survivor exercise guidelines were largely unknown, but movement, resilience and life balance were valued. Most participants reported at ≥1 mode of current PA (n = 24; 71% walking, 46% work/homesteading). Barriers to PA included treatment side effects, limited access to programs, fear of "over doing it," and family/friends encouraging rest. Preferences for PA varied.

Abstract
Binge drinking appears to be a risk factor, facilitator, and method of suicidal and non-suicidal self-injury for some American Indian (AI) youth. We examined characteristics, patterns, and motivations for binge use among AI adolescents (N = 69; 10-19 years-old) who recently engaged in binge drinking. The majority used alcohol alone (53.7%) or a combination of alcohol and marijuana (31.3%) for their binge event. Gender differences emerged with boys more severely affected than girls. Forty-seven percent reported lifetime suicidal thoughts. This study represents one of the first in-depth examinations of substance use and related behaviors among AI adolescents who have engaged in recent binge use.

Abstract
The growing national racial and ethnic diversity has created a greater need for health care delivery systems and health care providers to be more responsive to unique patient needs, that goes beyond meeting the immediate health problems to include attention to other critical component of patient care that take into account cultural competency such as health literacy, health beliefs and behaviors, cultural practices, etc.

Abstract
National concerns about reducing the persistent health disparities found among varying racial and ethnic populations have led to initiatives to improve health care delivery systems. Many of these initiatives also promote the cultural competence of health care providers as a way to meet unique patient needs that go beyond immediate health problems, and to account for other critical components of patient care, such as health literacy, health beliefs and behaviors, and cultural practices. This case study describes a patient-centered care model developed by the Chinle Comprehensive Health Care Facility on the Navajo Reservation in Arizona, a model that has added a cadre of traditional tribal practitioners as part of its hospital and other clinical service resources.

Abstract
Essentials Plasminogen activator inhibitor-1 (PAI-1) advanced cellular senescence in experiment studies. No population study exists on the association between PAI-1 and biological aging in American Indians. We found cross-sectional and longitudinal associations between higher PAI-1 and shorter telomere length. Our findings suggest a pathway linking PAI-1 with biological aging beyond metabolic factors. SUMMARY Background Plasminogen activator inhibitor-1 (PAI-1) promotes cellular aging both in vitro and in vivo. Telomere length is a marker of biological aging. Objectives To examine the cross-sectional and longitudinal associations between plasma PAI-1 and leukocyte telomere length in a large-scale epidemiological study of American Indians. Methods We measured leukocyte telomere length (LTL) and plasma PAI-1 in 2560 American Indians who were free of overt cardiovascular disease (CVD) and participated in the Strong Heart Family Study (SHFS) clinical examination in 2001-2003. LTL and PAI-1 were repeatedly measured in 475 participants who attended SHFS clinical visits in both 2001-2003 and 1998-1999. A generalized estimating equation model was used to examine the cross-sectional and longitudinal associations between PAI-1 and LTL, adjusting for known risk factors. Results A higher level of plasma PAI-1 was negatively associated with shorter age-adjusted LTL (β = -0.023; 95% CI, -0.034 to -0.013). This association was attenuated (β = -0.015; 95% CI, -0.029 to -0.002) after adjustments for demographics, study site, lifestyle (smoking, drinking and physical activity) and metabolic factors (obesity, blood pressure, fasting glucose, insulin, lipids and kidney function). Further adjustment for hsCRP did not change this association (β = -0.015; 95% CI, -0.029 to -0.001). Longitudinal analysis revealed that change in plasma PAI-1 was also inversely associated with change in LTL after adjusting for demographics, follow-up years, lifestyle factors, changes in metabolic factors, baseline levels of PAI-1 and LTL (β = -0.0005; 95% CI, -0.0009 to -0.0001). Conclusions A higher level of plasma PAI-1 was associated with shorter LTL in American Indians. This finding may suggest a potential role of PAI-1 in biological aging among American Indians.

Abstract
BACKGROUND This study examines the association between perceived neighborhood violence, perceived neighborhood collective efficacy, and binge drinking among Mexican Americans residing on the U.S.-Mexico border. METHODS Data were collected from a multistage cluster sample of adult Mexican Americans residing in the U.S.-Mexico border areas of California, Arizona, New Mexico, and Texas (N = 1,307). The survey weighted response rate was 67%. Face-to-face interviews lasting approximately 1 hour were conducted in respondents' homes in English or Spanish. Path analysis was used to test whether collective efficacy mediated the impact of perceived neighborhood violence on binge drinking. RESULTS Among 30+-year-old women, perceived neighborhood collective efficacy mediated the effects of perceived neighborhood violence on binge drinking in a theoretically predicted way: Lower perceptions of violence predicted an increased perception of collective efficacy, which in turn, predicted less binge drinking. Direct effects of violence perceptions on binge were nonsignificant. Younger 18- to 29-year-old women showed a similar (but nonsignificant) pattern of effects. Perceived collective efficacy also mediated the effects of perceived violence on binge drinking among men, but in opposite ways for older and younger men. Older men showed the same mediating effect as older women, but the effect reversed among younger men due to a strong, positive relation between collective efficacy and binge drinking. There were also age differences in the direct effect of violence perceptions on binge drinking: Perceptions of violence predicted more binge drinking among young men, but less among older men. CONCLUSIONS These results highlight the complexity of people's responses to neighborhood characteristics in regard to their drinking. Young men in particular seem to react very differently to perceptions of collective efficacy than other groups. However, among both men and women, collective efficacy may come to play an increasingly important protective role in health outcomes with age.

Abstract
OBJECTIVES Somali women are at increased risk of adverse pregnancy outcomes. Anxiety and perceived stigmatization toward female genital cutting (FGC) further fuels an atmosphere of miscommunication and distrust, contributing to poorer health outcomes. While the attitudes and experiences of Somali refugee women toward healthcare are widely known, the views of Somali refugee men are largely unknown. This study examines the perspectives of Somali men toward FGC and women's childbirth experiences in one refugee community in the USA. DESIGN Community-based participatory research partnerships with key stakeholders within the Somali refugee community incorporated qualitative methods comprising semi-structured focus groups and individual interviews to elicit male participants' perspectives on FGC, experiences during childbirth, and the perception of increased cesarean deliveries among Somali women. Qualitative analyses involved a framework and team-based approach using grounded theory and conventional content analysis. RESULTS Acculturation influenced changes in traditional gender roles fostering new dynamics in shared decision-making within the household and during childbirth. Participants were aware of FGC-related morbidity, ongoing matriarchal support for FGC, and were generally not supportive of FGC. They perceived health-care providers as being unfamiliar with caring for women with FGC fueling profound aversion to cesarean deliveries, miscommunication, and distrust of the health-care system. CONCLUSION Our work yields new insights into Somali reproductive healthcare through Somali men, namely: strong matriarchal support of FGC, discomfort in men's presence during delivery, and a strong aversion to cesarean delivery. Our findings support the need for advocacy to engage Somali women, their partners/spouses, and health-care providers in facilitating greater continuity of care, building greater trust as men become engaged throughout the spectrum of care in the decision-making process while respecting traditional norms. Cultural health navigators should bridge communication and support between providers and patients. Our work provides foundational knowledge to inform culturally appropriate health interventions within a Somali refugee community.

Abstract
BACKGROUND Hepatitis A (HAV) incidence has decreased in the United States, yet regional disparities persist. The role of international travel has become increasingly important in HAV transmission. We compared the relative burden of HAV in border and non-border regions in Arizona and examined the role of travel in sustaining HAV transmission. METHODS HAV vaccination coverage was calculated by age and region, using Arizona State Immunization Information System data. Incidence, demographics, and risk factors of cases reported through Arizona's infectious disease surveillance system between 2006 and 2011 were analyzed. RESULTS Hepatitis A incidence was higher in the border region of Arizona. Compared with the rest of Arizona, one-dose coverage in children<15 years was lower in the border region until 2008. Second dose coverage was lower in the border region, particularly among Spanish speakers. International travel among cases was generally high; however, in the border region cases were more likely to visit Mexico or South/Central America (94% vs. 80%, P value = 0.01) and be Hispanic (68% vs. 42%, P value = 0.0003). CONCLUSIONS Rates of HAV continue to be higher in the Arizona border region; the risk appears particularly high among Hispanics with recent travel in the Americas. Border surveillance should be emphasized, along with vaccination of all travelers, to continue to decrease and control HAV.

Abstract
BACKGROUND Acculturation to life in the United States is a known predictor of Hispanic drinking behavior. We compare the ability of 2 theoretical models of this effect-sociocultural theory and general stress theory-to account for associations between acculturation and drinking in a sample of Mexican Americans. Limitations of previous evaluations of these theoretical models are addressed using a broader range of hypothesized cognitive mediators and a more direct measure of acculturative stress. In addition, we explore nonlinearities as possible underpinnings of attenuated acculturation effects among men. METHODS Respondents (N = 2,595, current drinker N = 1,351) were interviewed as part of 2 recent multistage probability samples in a study of drinking behavior among Mexican Americans in the United States. The ability of norms, drinking motives, alcohol expectancies, and acculturation stress to account for relations between acculturation and drinking outcomes (volume and heavy drinking days) were assessed with a hierarchical linear regression strategy. Nonlinear trends were assessed by modeling quadratic effects of acculturation and acculturation stress on cognitive mediators and drinking outcomes. RESULTS Consistent with previous findings, acculturation effects on drinking outcomes were stronger for women than men. Among women, only drinking motives explained acculturation associations with volume or heavy drinking days. Among men, acculturation was linked to increases in norms, and norms were positive predictors of drinking outcomes. However, adjusted effects of acculturation were nonexistent or trending in a negative direction, which counteracted this indirect normative influence. Acculturation stress did not explain the positive associations between acculturation and drinking. CONCLUSIONS Stress and alcohol outcome expectancies play little role in the positive linear association between acculturation and drinking outcomes, but drinking motives appear to at least partially account for this effect. Consistent with recent reports, these results challenge stress models of linear acculturation effects on drinking outcomes and provide (partial) support for sociocultural models. Inconsistent mediation patterns-rather than nonlinearities-represented a more plausible statistical description of why acculturation-drinking associations are weakened among men.

Abstract
INTRODUCTION Diabetes is a growing worldwide problem, characterized by considerable ethnic variation and being particularly common in modernizing populations. Modernization is accompanied by a variety of stressful sociocultural changes that are believed to increase the risk of diabetes. Unfortunately, there is little accurate knowledge about impact of stress on the risk of diabetes in the US-Mexico border area. METHODS Literature searches were performed in PubMed and Google Scholar to identify anthropological studies on stress and diabetes. Snowball and opportunistic sampling were used to expand the identified literature. In total, 30 anthropological studies were identified concerning the role of stress and modernization on diabetes among Indigenous peoples. This article reviews the available information regarding stress and diabetes in different populations from various anthropological perspectives. RESULTS Four different concepts of stress were indentified: physiological, psychological, psychosocial and nutritional stress. Unlike physiological and nutritional theories of diabetes, psychological and psychosocial theories of stress and disease lack etiological specificity. No study addressed all four concepts of stress and few studies addressed more than two concepts. Most studies concerned nutritional stress and the developmental origins of diabetes. Most studies were conducted on the Pima Indians of Arizona and Mexico. All four stress concepts have some evidence as determinants of diabetes. CONCLUSION These theoretical concepts and ethnographic results can provide the basis for developing comprehensive research protocols and public health intervention targeted at diabetes. A comprehensive view of stress can potentially explain the high prevalence of diabetes in developing countries and among Indigenous peoples. These results can be used to inform public health interventions aimed at reducing diabetes in the US-Mexico border region or similar areas, help identify at-risk individuals, and guide health education and promotion.

Abstract
Active adult, age-restricted communities are significant to urban history and city planning. As communities that ban the permanent residence of children under the age of nineteen with senior zoning overlays, they are unique experiments in social planning. While they do not originate the concept of the common interest community with its shared amenities, the residential golf course community, or the gated community, Sun Cities and Leisure Worlds do a lot to popularize those physical planning concepts. The first age-restricted community, Youngtown, AZ, opened in 1954. Inspired by amenity-rich trailer courts in Florida, Del Webb added the “active adult” element when he opened Sun City, AZ, in 1960. Two years later, Ross Cortese opened the first of his gated Leisure Worlds. By the twenty-first century, these “lifestyle” communities had proliferated and had expanded their appeal to around 18 percent of retirees, along with influencing the design of intergenerational communities.

Abstract
I analyze the case of humanitarian pro-migrant activists in southern Arizona between 2000 and 2010 to explore how contending groups wield law and legality claims in a dynamic policy environment. Humanitarian activists both evade and engage the law. They appeal to a higher law to elude charges that they are acting illegally, while seeking assurances that their actions are within the law. Law enforcement agents rely on the authority and technical neutrality of the law in redefining humanitarian aid as illegal, while expanding their own claims to carry out humanitarian work. This case study of advocacy on behalf of “illegal” migrants highlights how both activists and those who enforce the law redefine legality in strategic ways.

Abstract
OBJECTIVE To examine the prognostic significance of elevated albuminuria in youth with type 2 diabetes. PATIENTS AND METHODS Cross-sectional and prospective studies were conducted on Pima Indian youth aged 5 to 19 years at baseline who were examined between July 1, 1982, and December 31, 2007. Prevalence and sequential changes in the level of microalbuminuria (30 < or = albumin-to-creatinine ratio [ACR] < 300 mg/g) and macroalbuminuria (ACR > or = 300 mg/g) and incidence of macroalbuminuria were computed according to the presence or absence of type 2 diabetes. RESULTS The prevalence of microalbuminuria and macroalbuminuria was 6.5% and 0.6% in the 3856 nondiabetic youth and 18.5% and 2.9% in the 103 youth with diabetes, respectively. One hundred forty-one of 187 (75.4%) nondiabetic youth, but only 1 of 14 (7.1%) diabetic youth with an elevated ACR (> or =30 mg/g) regressed to an undetectable or normal ACR (<30 mg/g) on subsequent examination. In a subset of 2666 youth with a median follow-up of 8.1 years, 36 nondiabetic and 30 diabetic youth with baseline ACRs of <300 mg/g developed macroalbuminuria. For a given ACR, the incidence of macroalbuminuria was 15.9-fold (95% confidence interval: 11.1-22.6) higher in the diabetic than in the nondiabetic youth. CONCLUSIONS Elevated albuminuria is infrequent and largely transient in nondiabetic youth, but it is relatively frequent and largely persistent in those with diabetes. Microalbuminuria in youth with type 2 diabetes strongly predicts progression to macroalbuminuria, which supports annual screening for albuminuria.

Abstract
Light rail transit (LRT) is increasingly accompanied by overlay zoning which specifies the density and type of future development to encourage landscapes conducive to transit use. Neighbourhood type (based on land use mix) is used to partition data and investigate how pre-existing land use, treatment with a park-and-ride (PAR) versus walk-and-ride (WAR) station and overlay zoning interrelate. Hedonic models estimate capitalisation effects of LRT-related accessibility and overlay zoning on single-family houses and condos in different neighbourhoods for the system in metropolitan Phoenix, Arizona. Impacts differ by housing and neighbourhood type. Amenity-dominated mixed-use neighbourhoods-predominantly WAR communities-experience premiums of 6 per cent for single-family houses and over 20 per cent for condos, the latter boosted an additional 37 per cent by overlay zoning. Residential neighbourhoods-predominantly PAR communities-experience no capitalisation benefits for single-family houses and a discount for condos. The results suggest that land use mix is an important variable to select comparable neighbourhoods.

Abstract
BACKGROUND The deceleration time of early mitral inflow (E) is shortened by left ventricular chamber stiffening and prolonged by impaired relaxation. For any given rate of deceleration of early mitral inflow, a higher E-wave velocity (E) is associated with a longer deceleration time. It is not known whether deceleration time normalized for E-velocity or its inverse (deceleration slope) better predicts cardiovascular (CV) events compared with deceleration time or E-velocity alone. METHODS We compared the prognostic value of deceleration time, E-velocity, deceleration time/E-velocity, and deceleration slope in 3102 American Indian participants in the Strong Heart Study, free of clinical CV disease and documented atrial fibrillation, in predicting fatal and nonfatal CV events. RESULTS During a mean of 8.5 +/- 2.4 years, there were 637 fatal and nonfatal CV events. After adjustment for traditional CV risk factors, deceleration time/E-velocity (adjusted hazard ratio [HR], 1.09; 95% confidence interval [CI], 1.00-1.18; P = .04 for every 0.89 msec/[cm/s] [1 + standard deviation {SD}] increase) and deceleration slope (HR, 0.91; 95% CI, 0.82-1.00; P = .01 for every 91 msec [1 + SD] increase) predicted CV events, whereas deceleration time and E-velocity did not. When participants with restrictive-type filling (n = 74) were removed from the analysis, deceleration time/E-velocity (HR, 1.10; 95% CI, 1.01-1.20; P = .03 for every 0.89 msec/[cm/s] [1 + SD] increase) and deceleration slope (HR, 0.64; 95% CI, 0.36-0.91; P = .01 for every 91 msec [1 + SD] increase) predicted CV events even more strongly. CONCLUSION In a large population-based sample with high prevalences of hypertension and diabetes, free of prevalent CV disease, deceleration time/E-velocity and deceleration slope predict CV events, whereas their components (deceleration time and E-velocity) do not. This suggests normalization of deceleration time for E-velocity or using its inverse (deceleration slope) more precisely captures prognostically significant prolongation of deceleration than does deceleration time alone.

Abstract
BACKGROUND Despite growing recognition that asthma is an important cause of morbidity among American Indians, there has been no systematic study of this disease in older adults who are likely to be at high risk of complications related to asthma. Characterization of the impact of asthma among American Indian adults is necessary in order to design appropriate clinical and preventive measures. METHODS A sample of participants in the third examination of the Strong Heart Study, a multicenter, population-based, prospective study of cardiovascular disease in American Indians, completed a standardized respiratory questionnaire, performed spirometry, and underwent allergen skin testing. Participants were > or = 50 years old. RESULTS Of 3,197 participants in the third examination, 6.3% had physician-diagnosed asthma and 4.3% had probable asthma. Women had a higher prevalence of physician-diagnosed asthma than men (8.2% vs 3.2%). Of the 435 participants reported in the asthma substudy, morbidity related to asthma was high: among those with physician-diagnosed asthma: 97% reported trouble breathing and 52% had severe persistent disease. The mean FEV(1) in those with physician-diagnosed asthma was 61.3% of predicted, and 67.2% reported a history of emergency department visits and/or hospitalizations in the last year, yet only 3% were receiving regular inhaled corticosteroids. CONCLUSIONS The prevalence of asthma among older American Indians residing in three separate geographic areas of the United States was similar to rates in other ethnic groups. Asthma was associated with low lung function, significant morbidity and health-care utilization, yet medications for pulmonary disease were underutilized by this population.

Abstract
Insulin-like growth factor (IGF-I) and prolactin have been found to be associated with breast cancer risk and with mammographic density. In a pooled analysis from 4 geographic locations, we investigated the association of percent mammographic density with serum levels of IGF-I, IGFBP-3 and prolactin. The pooled data set included 1,327 pre- and postmenopausal women: Caucasians from Norway, Arizona and Hawaii, Japanese from Hawaii and Japan, Latina from Arizona, and Native Hawaiians from Hawaii. Serum samples were assayed for IGF-I, IGFBP-3 and prolactin levels using ELISA assays. Mammographic density was quantified using a computer-assisted density method. After stratification by menopausal status, multiple regression models estimated the relation between serum analytes and breast density. All serum analytes except prolactin among postmenopausal women differed significantly by location/ethnicity group. Among premenopausal subjects, IGF-I levels and the molar ratio were highest in Hawaii, intermediate in Japan and lowest in Arizona. For IGFBP-3, the order was reversed. Among postmenopausal subjects, Norwegian women had the highest IGF-I levels and women in Arizona had the lowest while women in Japan and Hawaii had intermediate levels. We observed no significant relation between percent density and IGF-I or prolactin levels among pre-and postmenopausal women. The significant differences in IGF-I levels by location but not ethnicity suggest that environmental factors influence IGF-I levels, whereas percent breast density varies more according to ethnic background than by location. Based on this analysis, the influence of circulating levels of IGF-I, IGFBP-3, and prolactin on percent density appears to be very small.

Abstract
The introduction of more efficacious treatments for diabetic kidney disease may slow its progression, but evidence for their effectiveness in populations is sparse. We examined trends in the incidence of clinical proteinuria, defined as a urinary protein-to-creatinine ratio >0.5 g/g, and diabetic end-stage renal disease (ESRD), defined as death from diabetic nephropathy or onset of dialysis, in Pima Indians with type 2 diabetes between 1967 and 2002. The study included 2189 diabetic subjects >/=25 years old. During follow-up, 366 incident cases of proteinuria occurred in the subset of 1715 subjects without proteinuria at baseline. The age-sex-adjusted incidence rate of proteinuria increased from 24.3 cases/1000 person-years (pyrs) (95% confidence interval (CI) 18.7-30.0) in 1967-1978 to 35.4 cases/1000 pyrs (95% CI 28.1-42.8) in 1979-1990 and 38.9 cases/1000 pyrs (95% CI 31.2-46.5) in 1991-2002 (P(trend)<0.0002). In each period, the age-sex-adjusted incidence of proteinuria increased with diabetes duration, but diabetes duration-specific incidence was stable throughout the study period (P=0.8). The age-sex-adjusted incidence of ESRD increased between 1967 and 1990 and declined thereafter. The incidence of proteinuria increased over 36 years in Pima Indians as the proportion of people with diabetes of long duration increased. On the other hand, the incidence of ESRD declined after 1990, coinciding with improved control of blood pressure, hyperglycemia, and perhaps other risk factors.

Abstract
BACKGROUND The present article presents equations for the prediction of coronary heart disease (CHD) in a population with high rates of diabetes and albuminuria, derived from data collected in the Strong Heart Study, a longitudinal study of cardiovascular disease in 13 American Indian tribes and communities in Arizona, North and South Dakota, and Oklahoma. METHODS AND RESULTS Participants of the Strong Heart Study were examined initially in 1989-1991 and were monitored with additional examinations and mortality and morbidity surveillance. CHD outcome data through December 2001 showed that age, gender, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein cholesterol, smoking, diabetes, hypertension, and albuminuria were significant CHD risk factors. Hazard ratios for ages 65 to 75 years, hypertension, LDL cholesterol > or = 160 mg/dL, diabetes, and macroalbuminuria were 2.58, 2.01, 2.44, 1.66, and 2.11 in men and 2.03, 1.69, 2.17, 2.26, and 2.69 in women, compared with ages 45 to 54 years, normal blood pressure, LDL cholesterol <100 mg/dL, no diabetes, and no albuminuria. Prediction equations for CHD and a risk calculator were derived by gender with the use of Cox proportional hazards model and the significant risk factors. The equations provided good discrimination ability, as indicated by a c statistic of 0.70 for men and 0.73 for women. Results from bootstrapping methods indicated good internal validation and calibration. CONCLUSIONS A "risk calculator" has been developed and placed on the Strong Heart Study Web site, which provides predicted risk of CHD in 10 years with input of these risk factors. This may be valuable for diverse populations with high rates of diabetes and albuminuria.

Abstract
OBJECTIVE To evaluate the effectiveness of gun-safety counseling, a gun-safety brochure, and a free gun lock in subsequent gun removal and safe storage. METHODS In a predominantly Hispanic pediatric clinic, gun-owning families were identified and assigned to either an intervention group (gun-safety counseling, gun-safety brochure, and a free gun lock) or a control group (usual anticipatory guidance). Families were resurveyed 1 month later for changes in the proportion of gun owners, changes in frequency of unloaded and locked gun storage, and changes to the use of locked storage. RESULTS Two hundred six (7.8%) of the 2649 parents initially surveyed kept guns in their households. At follow-up, 16% of the control group removed all guns from their homes as compared with 22% of the intervention group (P = .41). Among the families who received the intervention, 61.6% either removed all guns from their homes or improved their gun storage safety practice in some way. Only 26.9% of the families in the control group showed similar types of improvement (P<.001). In those households still with guns at follow-up, 50.9% of the intervention group had some type of improvement in safe gun storage compared with 12.3% of the control group (P<.001). More specifically, 25.0% in the intervention group improved the frequency of locked storage of guns compared with 4.8% of those in the control group (P = .003). Twenty-six percent of the intervention group improved the use of locked storage compared with 3.1% in the control group (P<.001). CONCLUSIONS A brief gun-safety counseling session supported with written information along with a gun lock giveaway resulted in significant improvements in safe gun storage behaviors. It did not significantly influence the removal of guns from the home. This study gives support to the recommendations of the American Academy of Pediatrics (Elk Grove Village, Ill) and other professional organizations to discuss gun safety with families and encourages research in this area. It also suggests that providing tools such as gun locks to enable the desired behavior may improve safe storage.

Abstract
OBJECTIVE To compare rates of motor vehicle crash (MVC) fatalities among different race/ethnic groups in urban and rural Arizona. METHOD Using the Fatality Analysis Reporting System and the National Center for Health Statistics Multiple Cause of Death file, MVC fatalities in Arizona from 1990-96 inclusive were classified by gender, race/ethnicity, and urban or rural residence. Age adjusted rates of total, occupant, pedestrian, and alcohol related fatalities were calculated. The total MVC fatality rate for each race/ethnic group was then adjusted for proportion of rural residence. RESULTS Compared with non-Hispanic whites (NHWs), American Indians had raised relative risks for MVC fatality in all gender and residence subgroups. Hispanic females and rural Hispanic males had lower relative risks, as did rural African-American men. Raised relative risks for American Indian men and women included all subgroups: total, occupant, pedestrian, and alcohol related. Hispanic and African-American men both had raised relative risks of pedestrian related fatalities, and Hispanic men had a slightly higher relative risk while Hispanic women had a lower relative risks, for alcohol related fatality. Hispanic men and women and African-American men had lower occupant fatality rates. Close to half (45%) of the excess MVC fatality among American Indians can be attributed to residence in rural areas, where MVC fatality rates are higher. There were 1.85 occupants in crashes involving NHW deaths compared with 2.51 for Hispanics and 2.71 for American Indians (p<0.001). The proportion of occupants not using a seatbelt was higher in Hispanics and American Indians in both urban and rural areas. CONCLUSION The major disparity in MVC fatality in Arizona is among American Indians. The higher MVC fatality rates among American Indians occur in all age groups, in both urban and rural areas, and among occupants and pedestrians. Rural residence, lower rates of seatbelt use, higher rates of alcohol related crashes, a greater number of occupants, and higher rates of pedestrian deaths all contribute to the American Indian MVC fatality disparity. High rates of pedestrian fatality occur in men in all three race/ethnic minorities in Arizona and among American Indian women. In contrast to other studies, African-Americans and Hispanics did not have raised total MVC fatality rates and compared to NHWs actually had lower rates in the rural areas of the state.

Abstract
American Indians residing on-reservation were interviewed regarding their substance use and treatment utilization. One-third had a current substance abuse problem. Predictors included gender, tribe, age, employment status, household income, and educational attainment. Almost two-thirds of those with substance abuse problems had received no treatment within the past year. A combination of formal and informal treatment was the most common approach. Treatment utilization was predicted by gender, age, and insurance coverage.

Abstract
BACKGROUND Rates of cardiovascular disease and its risk factors seem to be increasing in American Indian populations, yet these changes have received little documentation. OBJECTIVES To evaluate incidence rates of coronary artery disease, acute myocardial infarction, and cardiac events during a 10-year period (1987-1996); to assess cardiac risk factors for an American Indian tribe in Arizona. METHODS A retrospective medical chart review was performed for tribal members from January 1, 1987-December 31, 1996. Patient records with even minor indications of coronary disease were reviewed independently by 2 cardiologists of the Native American Cardiology Program. Multiple databases were reviewed in an effort to find all diagnoses, and incidence rates were calculated and analyzed for increasing trends. Cardiac risk factors were assessed in a population convenience sample. RESULTS From 1987 through 1996, the number of incident cases increased from 3 to 18 for coronary artery disease, 1 to 10 for acute myocardial infarction, and 3 to 26 for cardiac events. Statistically significant increasing trends were calculated for each. Of our youthful convenience sample, 49% had 2 or more cardiac risk factors. CONCLUSIONS This study confirms increasing rates of coronary artery disease and its comorbidities in this American Indian population and demonstrates high prevalence of cardiovascular risk factors among tribal members without extant coronary disease. This suggests that coronary disease will likely continue to increase as this population ages. To prevent such increases, culturally appropriate, aggressive preventive interventions are needed.

Abstract
PURPOSE This study was undertaken to determine whether differences in left ventricular (LV) and systemic hemodynamic findings exist between American Indians in different regions that might contribute to known differences in cardiovascular morbidity rates among American Indians. METHODS We compared echocardiography results in 290 non-diabetic Strong Heart Study (SHS) participants in Arizona, 595 in Oklahoma and 572 in North/South Dakota (ND/SD). RESULTS Participants in the 3 regions were similar in age and gender but those in Arizona had the highest body mass indices and lowest heart rates while those in ND/SD had the lowest diastolic blood pressures (BP). In analyses that adjusted for significant covariates, ND/SD participants had larger aortic (Ao) anular, Ao root, and LV chamber size as well as higher cardiac output and lower peripheral resistance, whereas Arizona participants had increased LV wall thickness and mass and reduced LV myocardial contractility. These findings may contribute to the known high rates of cardiovascular events in ND/SD Indians and to the proportionately higher rate of cardiovascular death than of non-fatal cardiovascular events that has been recently documented in Arizona Indians. CONCLUSIONS Application of echocardiography to non-diabetic SHS participants reveals that LV chamber and arterial size are larger in ND/SD Indians and that LV wall thicknesses and mass are higher and LV myocardial contractility lower in Arizona Indians, possibly contributing to the higher than expected rates of cardiovascular morbidity and mortality among Indians in Arizona.

Abstract
OBJECTIVE To establish the prevalence of shoulder disease and chronic widespread pain in Pima Indians. METHODS Cross sectional analyses of data from 4230 subjects for shoulder disease and 105 subjects for chronic widespread pain participating in population surveys RESULTS The prevalence of shoulder disease was 4.4% (95% CI, 3.8-5.1), age-sex adjusted to the 1980 US census population. This is lower than in a study of Caucasians [prevalence ratio (PR) = 0.29, 95% CI, 0.20-0.42 for men and PR = 0.55, 95% CI, 0.41-0.73 for women]. Shoulder disease was associated with non-insulin-dependent diabetes mellitus (PR = 1.67, 95% CI, 1.19-2.36). No chronic widespread pain was identified (95% CI, 0-3.5%). CONCLUSION Prevalence of these pain syndromes in Pima Indians is lower than in predominantly Caucasian populations. These findings suggest that these populations have different pain perception or different patterns of risk factors for these disorders.
