Healthcare Access and Utilization Among Women 40 and Older at the U.S.-Mexico Border: Predictors of a Routine Check-Up

Mexican Americans are more likely to experience barriers to access and utilization of healthcare services than any other U.S. Hispanic group. In Mexico, where the majority of the population has access to care, the pressing issue is the underutilization of preventive services among adults. This study was conducted to assess access and utilization barriers among a U.S.-Mexico border population. A cross-sectional, population-based survey was conducted during 1999–2000 in a pair of contiguous U.S.-Mexico border communities. Household surveys were administered to U.S. and Mexican women, 40 years of age and older, to assess healthcare access and utilization, participation in chronic disease screenings, orientation toward prevention and personal history of chronic disease. Analysis indicates few statistically significant differences (p < 0.05) among access and utilization variables by country. Mexican participants were more likely to have a regular source of care and to have had a blood sugar test within the past 12 months. U.S. participants more often reported having had a Pap smear and mammogram during the previous year. Factors independently positively associated with having had a routine check-up during the past 12 months included age and having a regular provider or place to go when sick. Only going to the doctor when ill was independently inversely associated with routine check-ups in the past 12 months. Findings suggest that U.S. and Mexican border populations are similar with regard to healthcare access and utilization characteristics. Efforts to increase utilization of preventive health screenings among women are needed at the U.S.-Mexico border.

Fat–Fit Patterns,Drug Consumption,and Polypharmacy in Older Adults: The EXERNET Multi-Center Study

Background: Physical fitness levels and the amount of accumulated adipose tissue (fatness) relate to current and future individuals’ heath status. Nevertheless, the interrelationships of their combined patterns with polypharmacy and the types of medications consumed have not been sufficiently investigated. Methods: This cross-sectional study was carried out in six Spanish regions between 2008 and 2009 with a sample of older community-dwelling adults (≥65 years old) without dementia or cancer. Fitness was measured with one-leg balance and senior fitness tests, as well as by measuring weight and fat mass with a bioelectrical impedance analyzer. Polypharmacy was defined as the use of five or more medications. An analysis of variance was performed for comparisons between the physical fitness and fatness patterns and the medication consumed. Results: A total of 1709 elders were included in the study (72.1 ± 5.2 years). The two unfit patterns were those with the highest drug consumption. The High-Fat–Unfit pattern was the one that had the most significant consumption and had the highest percentage of polymedicated subjects. The Low-Fat–Fit pattern had a significantly lower percentage of people that did not consume any medications. The highest percentages of drug consumption in 7 of the 10 groups that were included were concentrated in the two unfit patterns. Conclusions: This study highlights the importance of fitness in older adults, as it is at least as important as the avoidance of accumulation of excess fat with respect to the consumption of a smaller number of medicines.

Let’s Not Ignore a Growing HIV Problem for Asians and Pacific Islanders in the U.S.

Recent analyses reported in the Morbidity and Mortality Weekly Report (MMWR) show that among all racial groups in the U.S., Asians and Pacific Islanders (APIs) had the only statistically significant increases in HIV/AIDS diagnosis rates in the most recent four-year period. Yet this fact is not noted in the discussion or editorial notes in the MMWR issue where this information is reported. Because HIV rates in API communities are still relatively low, we have a critical opportunity to develop effective prevention programs for API American communities before these alarming indicators translate into markedly higher HIV prevalence in API communities in the U.S., as has occurred in other U.S. communities and in the Asia/Pacific region.

Evaluation of a methodology to validate National Death Index retrieval results among a cohort of U.S. service members

PurposeAccurate knowledge of the vital status of individuals is critical to the validity of mortality research. National Death Index (NDI) and NDI-Plus are comprehensive epidemiological resources for mortality ascertainment and cause of death data that require additional user validation. Currently, there is a gap in methods to guide validation of NDI search results rendered for active duty service members. The purpose of this research was to adapt and evaluate the CDC National Program of Cancer Registries (NPCR) algorithm for mortality ascertainment in a large military cohort.MethodsWe adapted and applied the NPCR algorithm to a cohort of 7088 service members on active duty at the time of death at some point between 2001 and 2009. We evaluated NDI validity and NDI-Plus diagnostic agreement against the Department of Defense's Armed Forces Medical Examiner System (AFMES).ResultsThe overall sensitivity of the NDI to AFMES records after the application of the NPCR algorithm was 97.1%. Diagnostic estimates of measurement agreement between the NDI-Plus and the AFMES cause of death groups were high.ConclusionsThe NDI and NDI-Plus can be successfully used with the NPCR algorithm to identify mortality and cause of death among active duty military cohort members who die in the United States.     

Requiring Consent vs. Waiving Consent for Medical Records Research: A Minnesota Law vs. the U.S. (HIPAA) Privacy Rule

The use of medical records in research can yield information that is difficult to obtain by other means. When such records are released to investigators in identifiable form, however, substantial privacy and confidentiality risks may be created. These risks become more common and more serious as medical records move to an electronic format. In 1996, the state of Minnesota enacted legislation with respect to consent requirements for the use of medical records in research. This legislation has been widely criticized because--it is claimed--it creates an unnecessary impediment to research. In this article, we show that these arguments rest upon misinterpretation and/or misrepresentation of the 1996 legislation. A consent requirement had actually been present in Minnesota since 1976 (though codified in a patient rights statute rather than a privacy statute). The 1996 law does not require specific consent, as often claimed, but rather only a general authorization. The campaign against the Minnesota legislation appears to have been motivated by concern with respect to the then impending federal privacy rule. The HIPAA rule, as enacted, is in fact less stringent with respect to consent than the Minnesota consent law. On the other hand, the Minnesota consent law has not been effectively applied or enforced. As we change the way we manage sensitive medical information, new efforts are needed to provide protection against the confidentiality risks in research. Patient consent is an important tool in this regard. New instrumentalities are needed to solicit and document consent.     

Nutritional Status of Non-Institutionalized Adults Aged over 65. Study of Weight and Health in Older Adults (PYSMA)

Background. A significant increase in the prevalence of malnourishment, obesity, and sarcopenic obesity has been observed in developed countries over the last few decades. In Spain, this especially happens in populations over 65 who are not institutionalized. Differences in lifestyle, medication, and economic capacity partially explain this increase. Objective. To study the nutritional status of a population of 65 year-olds and subjects who are not institutionalized, in the Cádiz region (Spain). Methods. Observational, transversal study carried out on 2621 subjects who are 65 years old and over, with a direct weight and height measurement, in 150 pharmacy offices from 44 locations. A mobile application was designed for homogeneous data collection in all the pharmacy offices. The data required from all subjects was gender, age, postal code, social security contribution regime, if the patient lives alone, type of food consumed as the main meals, level of physical activity, polypharmacy, weight, and height. Results. The prevalence of overweight and obesity amounts to 82.2% of the population (43.2% overweight and 39% obese). We found an inverse relationship between the prevalence of overweight and obesity with carrying out physical activity and having full dinners. Conclusion. We identify the need to reinforce the messages to the elderly aimed at maintaining adequate physical activity and assessing the quality and quantity of dinners, as well as reducing, as much as possible, the treatments that may lead to weight gain.     

Using geographically weighted regression for social inequality analysis: association between mentally unhealthy days (MUDs) and socioeconomic status (SES) in U.S. counties

This research explores geographic variability of factors on social inequality related to mental health in the United States using county-level data in 2014. First, we account for complex design factors in Behavioural Risk Factor Surveillance System (BRFSS) data such as clustering, stratification, and sample weight using Complex Samples General Linear Model (CSGLM). Then, three variables are used in the model as indicators of social inequality, low socioeconomic status (SES): unemployment, education status, and social association status. A geographically weighted regression analysis is applied to examine the spatial variations in the associations of mentally unhealthy days (MUDs) with the indicators of SES in the United States. The results demonstrate that unemployment and education level show global positive and negative influences respectively on MUDs. Social association status ranged from positive to negative across the United States, implying some geographic clustering. These findings suggest that social and health policies should be adjusted to address the different effects of indicators of social inequality on mental health across different social characteristics of communities to more effectively manage mental health problems.     

Interventions to Improve Clinical Outcomes in Older Adults Admitted to a Surgical Service: A Systematic Review and Meta-analysis

ObjectivesManaging older patients with surgical conditions is a major challenge for hospitals. There is therefore a growing interest in providing geriatric perioperative services. The aim of this systematic review and meta-analysis was to characterize and assess the impact of targeted perioperative geriatric interventions on clinical outcomes of older adults admitted to nonorthopedic surgical teams.Design, Setting and ParticipantsA systematic review and meta-analysis of studies of perioperative geriatric interventions in older adults hospitalized under nonorthopedic surgical teams.MethodsOvid MEDLINE, EMBASE, PsycINFO, Scopus, Cochrane Central Register of Controlled Trials, CINAHL, and trial registry databases were searched. Primary outcomes were change in functional status and length of stay (LOS).ResultsFifteen randomized controlled trials (RCTs) and 9 prospective before-and-after studies met the inclusion criteria (n = 3026 participants). Perioperative geriatric interventions included preoperative comprehensive geriatric assessment and management (CGA) (5 studies), multicomponent inpatient geriatric programs (8 studies), cognitive training (1 study), exercise (5 studies), and prehabilitation (5 studies). Exercise therapy [mean difference (MD) −1.90, 95% confidence interval (CI) −3.01, −0.80], multicomponent inpatient geriatric programs (MD –1.98, 95% CI –3.09, −0.88), and prehabilitation (MD –1.32, 95% CI –2.75, 0.11) reduced LOS. Functional decline was highly heterogeneous, with 4 of 8 studies reporting significantly less functional decline. Geriatric perioperative interventions reduced complications [exercise therapy risk ratio (RR) 0.74, 95% CI 0.48, 1.15; prehabilitation RR 0.61, 95% CI 0.47, 0.80] and delirium (multicomponent inpatient geriatric programs RR 0.49, 95% CI 0.27, 0.90; preoperative CGA RR 0.54, 95% CI 0.33, 0.89). There was no significant impact on mortality or readmissions.Conclusions and ImplicationsPerioperative geriatric interventions targeted at older nonorthopedic surgical patients improve some clinically relevant outcomes. There is a need for these interventions to be further evaluated in high-quality studies, and future research should explore how to effectively implement these interventions within complex health care systems.     

Institutional structures: Catalysts of or barriers to quality care for the institutionalized aged in Scotland and the U.S.

The care of the elderly in two long-term care institutions, one in Scotland and one in the United States, is described, compared, and analyzed. In Scotland three institutional structures, the National Health Service, the Geriatric Service, and the specialty of geriatrics are identified as catalysts of quality care. In the U.S. Medicare and Medicaid, the absence of geriatrics as a specialty, and the nursing home are identified as barriers to quality care for the institutionalized aged. The findings suggest that three components, an adequate government insurance program, professionals who specialize in the care of the aged, and a structure to provide continuing comprehensive care, are essential for a successful program of care for the institutionalized elderly.     

The Development of a Decision Tool for the Empiric Treatment of Suspected Urinary Tract Infection in Frail Older Adults: A Delphi Consensus Procedure

Objectives

Nonspecific signs and symptoms combined with positive urinalysis results frequently trigger antibiotic therapy in frail older adults. However, there is limited evidence about which signs and symptoms indicate urinary tract infection (UTI) in this population. We aimed to find consensus among an international expert panel on which signs and symptoms, commonly attributed to UTI, should and should not lead to antibiotic prescribing in frail older adults, and to integrate these findings into a decision tool for the empiric treatment of suspected UTI in this population.

We carry history within us: Anti-Black racism and the legacy of lynchings on life expectancy in the U.S. South

The United States lags in life expectancy compared to most of the world's similarly wealthy nations, driven by pronounced regional disparities particularly between the South and the rest of the country. The U.S. South has a violent history of lynchings of Black Americans by White mobs after the ending of slavery and up to the Civil Rights Era. Building on critical race scholarship, the objective of this study was to determine whether there exists an association between historical lynchings and overall life expectancies in the U.S. South. We created a cross-sectional county-level data set with 1221 data points utilizing data from the Equal Justice Initiative and Robert Wood Johnson Foundation Country Health Rankings. The average life expectancy for 2019–2020 was 76.1 years, ranging from 68.2 years to 90.2 years. Overall life expectancy was found to be highest (76.6) in counties with no recorded lynchings, and lowest (75.5) in counties with the most lynchings (p < .001). In the spatially enabled regression model, the history of lynching along with other covariates explained 57.1% of the variance in life expectancies across the study area. Counties with a history of lynchings also score lower compared to the reference group in various socioeconomic indicators, including median household incomes and high school graduation rates. The findings suggest that lynchings were pivotal in creating the social and physical environment affecting health outcomes in the U.S. South today. We call for further public health research which acknowledges and explores this form of violent and institutional anti-Black racism as foundational to the nation's regional health disparities.

Women who quit maquiladora work on the U.S.-Mexico border: Assessing health,occupation, and social dimensions in two transnational electronics plants

This cohort study of 725 women examined the health, occupational, and social factors that contribute to quitting work in two transnational electronics maquiladoras (assembly plants) in Tijuana, Mexico. The estimated cumulative probabilities of quitting were 68% and 81% by 1 and 2 years of employment. After adjusting for other factors, women who had a history of smoking or surgery and those who returned to work after a paid leave due to illness were more likely to quit. In contrast, women with a history of chronic illness had lower quitting rates. The nationality of the company and the work shift also significantly influenced quitting rates, but demographic characteristics and health care visits did not have a significant effect. Women selectively leave maquiladora employment, often due to health-related events. The healthy worker effect is difficult to measure in a mobile population with high turnover. Am. J. Ind.
