Neighborhood Socioeconomic Status, Green Space, and Walkability and Risk for Falls Among Postmenopausal Women: The Women's Health Initiative.

PURPOSE: This study estimated associations between neighborhood socioeconomic status (NSES), walkability, green space, and incident falls among postmenopausal women and evaluated modifiers of these associations, including study arm, race and ethnicity, baseline household income, baseline walking, age at enrollment, baseline low physical functioning, baseline fall history, climate region, and urban-rural residence. METHODS: The Women's Health Initiative recruited a national sample of postmenopausal women (50-79 years) across 40 U.S. clinical centers and conducted yearly assessments from 1993 to 2005 (n = 161,808). Women reporting a history of hip fracture or walking limitations were excluded, yielding a final sample of 157,583 participants. Falling was reported annually. NSES (income/wealth, education, occupation), walkability (population density, diversity of land cover, nearby high-traffic roadways), and green space (exposure to vegetation) were calculated annually and categorized into tertiles (low, intermediate, high). Generalized estimating equations assessed longitudinal relationships. RESULTS: NSES was associated with falling before adjustment (high vs. low, odds ratio, 1.01; 95% confidence interval, 1.00-1.01). Walkability was significantly associated with falls after adjustment (high vs. low, odds ratio, 0.99; 95% confidence interval, 0.98-0.99). Green space was not associated with falling before or after adjustment. Study arm, race and ethnicity, household income, age, low physical functioning, fall history, and climate region modified the relationship between NSES and falling. Race and ethnicity, age, fall history, and climate region modified relationships between walkability and green space and falling. CONCLUSIONS: Our results did not show strong associations of NSES, walkability, or green space with falling. Future research should incorporate granular environmental measures that may directly relate to physical activity and outdoor engagement.

Quantifying structural racism in cohort studies to advance prospective evidence.

Calls-to-action in health research have described a need to improve research on race, ethnicity, and structural racism. Well-established cohort studies typically lack access to novel structural and social determinants of health (SSDOH) or precise race and ethnicity categorization, contributing to a loss of rigor to conduct informative analyses and a gap in prospective evidence on the role of structural racism in health outcomes. We propose and implement methods that prospective cohort studies can use to begin to rectify this, using the Women's Health Initiative (WHI) cohort as a case study. To do so, we evaluated the quality, precision, and representativeness of race, ethnicity, and SSDOH data compared with the target US population and operationalized methods to quantify structural determinants in cohort studies. Harmonizing racial and ethnic categorization to the current standards set by the Office of Management and Budget improved measurement precision, aligned with published recommendations, disaggregated groups, decreased missing data, and decreased participants reporting "some other race". Disaggregation revealed sub-group disparities in SSDOH, including a greater proportion of Black-Latina (35.2%) and AIAN-Latina (33.3%) WHI participants with income below the US median compared with White-Latina (42.5%) participants. We found similarities in the racial and ethnic patterning of SSDOH disparities between WHI and US women but less disparity overall in WHI. Despite higher individual-level advantage in WHI, racial disparities in neighborhood resources were similar to the US, reflecting structural racism. Median neighborhood income was comparable between Black WHI ($39,000) and US ($34,700) women. WHI SSDOH-associated outcomes may be generalizable on the basis of comparing across race and ethnicity but may quantitatively (but not qualitatively) underestimate US effect sizes. This paper takes steps towards data justice by implementing methods to make visible hidden health disparity groups and operationalizing structural-level determinants in prospective cohort studies, a first step to establishing causality in health disparities research.

Resiliency Among Women's Health Initiative Women Aged 80 and Older by Race, Ethnicity, and Neighborhood Socioeconomic Status.

OBJECTIVES: A comprehensive examination of resilience by race, ethnicity, and neighborhood socioeconomic status (NSES) among women aged ≥80 is needed, given the aging of the U.S. population, increasing longevity, and growing racial and ethnic diversity. METHODS: Participants were women aged ≥80 enrolled in the Women's Health Initiative. Resilience was assessed with a modified version of the Brief Resilience Scale. Descriptive statistics and multiple linear regression examined the association of demographic, health, and psychosocial variables with resilience by race, ethnicity, and NSES. RESULTS: Participants (n = 29,367, median age = 84.3) were White (91.4%), Black (3.7%), Hispanic (1.9%), and Asian (1.7%) women. There were no significant differences by race and ethnicity on mean resiliency scores (p = .06). Significant differences by NSES were observed regarding mean resiliency scores between those with low NSES (3.94 ± 0.83, out of 5) and high NSES (4.00 ± 0.81). Older age, higher education, higher self-rated health, lower stress, and living alone were significant positive correlates of resilience in the sample. Social support was correlated with resilience among White, Black, and Asian women, but not for Hispanic women. Depression was a significant correlate of lower resilience, except among Asian women. Living alone, smoking, and spirituality were significantly associated with higher resilience among women with moderate NSES. DISCUSSION: Multiple factors were associated with resilience among women aged ≥80 in the Women's Health Initiative. Despite some differing correlates of resilience by race, ethnicity, and NSES, there were many similarities. These results may aid in the design of resilience interventions for the growing, increasingly diverse population of older women.

[Perceptions and external factors of physical activity in adolescents using mixed methods]. / Percepciones y factores externos de la actividad física en adolescentes mediante métodos mixtos.

OBJECTIVE: Analyze the levels of physical activity in adolescents and their relationship with perceptions of physical activity and external factors. METHOD: Cross-sectional descriptive observational study. The participants were adolescents between the ages of 11 and 18. They were recruited in secondary schools in the municipality of Esplugues de Llobregat, Barcelona, Spain. The measurements were amount of physical activity (IPAQ-A questionnaire) and the relationship between level of physical activity and the perceptions of physical activity and external factors proposed by the health promotion model. RESULTS: Of the total sample, 60.34% participants were insufficiently active. The factors positively associated with physical activity were male gender (p<0.01), engaging in extracurricular sports (p<0.01), perceiving benefits (p<0.01), perceiving self-efficacy (p<0.01), interpersonal influences (p<0.01), having parents who engage in sports (p<0.01), social support (p<0.01) and social norms supporting exercise (p<0.01). The factors negatively associated with physical activity were female gender (p<0.01), body mass index (p=0.048) and perceiving obstacles (p<0.01). There was no relationship with social class (p=0.164). Situational influences were a conditioning factor for boys (p<0.01), but not girls (p=0.561). CONCLUSIONS: This study identifies factors that determinate the practice of physical activity in adolescents. Taking these factors into account in the design of health promotion interventions and policies could help increase levels of physical activity in this population. Even so, there are some variables, such as gender and socioeconomic status, that should be explored in depth through research that is more exploratory and discursive.

Sugar-sweetened beverage purchases in urban Peru before the implementation of taxation and warning label policies: a baseline study.

BACKGROUND: Sugar-sweetened beverage consumption is associated with obesity and chronic disease. In 2018, Peru increased the tax on high-sugar beverages (≥6 g of sugar per 100 mL) from 17 to 25%, yet little is known about pre-existing beverage trends or demographic characteristics associated with purchases in the country. The aim of this study was to explore beverage purchasing trends from 2016 to 2017 and examine variation in purchase volume by sociodemographic characteristics among urban households in Peru. METHODS: This study used monthly household purchase data from a panel of 5145 households from January 2016-December 2017 from Kantar WorldPanel Peru. Beverage purchases were categorized by type and tax status under the 2018 regulation (untaxed, lower-sugar taxed, high-sugar taxed). To assess beverage purchasing trends, per-capita volume purchases were regressed on a linear time trend, with month dummies for seasonality and clustered standard errors. Mean volume purchases by beverage tax status (total liters purchased per month), overall and by key demographic characteristics (education, socioeconomic status, and geographic region), were calculated. Mean volume by beverage type was assessed to identify the largest contributors to total beverage volume. RESULTS: The trends analysis showed a decline in total beverage volume of - 52 mL/capita/month (95% CI: - 72, - 32) during the 24-month study period. Over 99% of households purchased untaxed beverages in a month, while > 92% purchased high-sugar taxed beverages. Less than half of all households purchased low-sugar taxed beverages in a month and purchase volume was low (0.3 L/capita/month). Untaxed beverage purchases averaged 9.4 L/capita/month, while households purchased 2.8 L/capita/month of high-sugar taxed beverages in 2017. Across tax categories, volume purchases were largest in the high education and high socioeconomic (SES) groups, with substantial variation by geographic region. The highest volume taxed beverage was soda (2.3 L/capita/month), while the highest volume untaxed beverages were milk and bottled water (1.9 and 1.7 L/capita/month, respectively). CONCLUSIONS: Nearly all households purchased high-sugar taxed beverages, although volume purchases of taxed and untaxed beverages declined slightly from 2016 to 2017. Households with high SES and high education purchased the highest volume of taxed beverages, highlighting the need to consider possible differential impacts of the tax policy change by sub-population groups.

The Association of Neighborhood Changes with Health-Related Quality of Life in the Women's Health Initiative.

Longitudinal studies can help us understand the effects of long-term neighborhood changes, as these can capture individual self-appraisal of current and future circumstances. We analyzed the association between neighborhood changes and health-related quality of life (HRQoL) outcomes among older women from the Women's Health Initiative (WHI) study. We used a subset (n = 49,254) of the longitudinal WHI dataset of female participants, aged 50-79 at baseline, recruited from 40 clinical centers across the U.S. beginning in 1993. Two HRQoL outcomes were explored: self-rated quality of life (SRQoL), and physical functioning-related quality of life (PFQoL). We used U.S. census tract-level changes in median household income between the 2000 census and 2007-2011 American Community Survey to classify neighborhoods as "upgrading," "declining," or "stable." Multi-level models were used to identify significant associations between neighborhood change and HRQoL outcomes over time. Compared to participants residing in upgrading neighborhoods, participants in stable and declining neighborhoods reported significantly lower PFQoL. A significant interaction was observed with income such that the effect of neighborhood change was greater at lower levels of income.

Taking action to advance the study of race and ethnicity: the Women's Health Initiative (WHI).

"Race" and "ethnicity" are socially constructed terms, not based on biology - in contrast to biologic ancestry and genetic admixture - and are flexible, contested, and unstable concepts, often driven by power. Although individuals may self-identify with a given race and ethnic group, as multidimensional beings exposed to differential life influencing factors that contribute to disease risk, additional social determinants of health (SDOH) should be explored to understand the relationship of race or ethnicity to health. Potential health effects of structural racism, defined as "the structures, policies, practices, and norms resulting in differential access to goods, services, and opportunities of society by "race," have been largely ignored in medical research. The Women's Health Initiative (WHI) was expected to enroll a racially and ethnically diverse cohort of older women at 40 U.S. clinical centers between 1993 and 1998; yet, key information on the racial and ethnic make-up of the WHI cohort of 161,808 women was limited until a 2020-2021 Task Force was charged by the WHI Steering Committee to better characterize the WHI cohort and develop recommendations for WHI investigators who want to include "race" and/or "ethnicity" in papers and presentations. As the lessons learned are of relevance to most cohorts, the essence of the WHI Race and Ethnicity Language and Data Interpretation Guide is presented in this paper. Recommendations from the WHI Race and Ethnicity Language and Data Interpretation Guide include: Studies should be designed to include all populations and researchers should actively, purposefully and with cultural-relevance, commit to recruiting a diverse sample; Researchers should collect robust data on race, ethnicity and SDOH variables that may intersect with participant identities, such as immigration status, country of origin, acculturation, current residence and neighborhood, religion; Authors should use appropriate terminology, based on a participant's self-identified "race" and "ethnicity", and provide clear rationale, including a conceptual framework, for including race and ethnicity in the analytic plan; Researchers should employ appropriate analytical methods, including mixed-methods, to study the relationship of these sociocultural variables to health; Authors should address how representative study participants are of the population to which results might apply, such as by age, race and ethnicity.

Assessment of apolipoprotein E genotype for ß-amyloid status prediction.

BACKGROUND: Apolipoprotein E (ApoE) is the major genetic risk factor for sporadic Alzheimer's Disease (AD). Some studies showed a relationship between ApoE4 genotype and the cerebrospinal fluid (CSF) biomarkers (ß-amyloid42, p-Tau, t-Tau), as well as with cognitive status. In this sense, it could be interesting to develop an approach to establish amyloid status in a minimally invasive way. METHODS: The present study assessed the ApoE genotype in different participant groups (mild cognitive impairment due to AD (MCI-AD), mild/moderate dementia due to AD, MCI not due to AD (MCI not AD), other neurological diseases, healthy participants) (n = 342). RESULTS: As expected, the ApoE4 allele was more prevalent in AD patients, characterized by impairment in CSF ß-amyloid42 levels (Aß +), than in the other groups (Aß -). In this sense, ApoE4-carrier subjects showed lower CSF levels for ß-amyloid42 and higher CSF levels for t-Tau and p-Tau. From this, a multivariate model to predict Aß status was developed by means of partial least square analysis (PLS) and predictive variables (ApoE genotype, cognitive score, sex, age). This model showed suitable AUC-ROC 0.792 (95% CI, 0.744-0.840) and predictive negative value (81.6%). CONCLUSION: ApoE genotype could be useful in detecting CSF ß-amyloid42 impairment associated with early AD development.

Plasma isoprostanoids assessment as Alzheimer's disease progression biomarkers.

Alzheimer's Disease (AD) is the most common neurodegenerative disease worldwide. So, there is a need to identify AD early diagnosis and monitoring biomarkers in blood samples. The aim of this study was to analyse the utility of lipid peroxidation biomarkers in AD progression evaluation. Participants (n = 19) were diagnosed with AD at early stages (Time 0, T0), and they were re-evaluated 2 years later (Time 1, T1). Plasma biomarkers from AD patients were determined at both times. Some analytes, such as dihomo-isoprostanes (17-epi-17-F2t-dihomo-IsoP, 17-F2t-dihomo-IsoP, Ent-7(RS)-7-F2t-dihomo-IsoP), and neuroprostanes (10-epi-10-F4t-NeuroP) showed very high probability of showing an increasing trend over time. Baseline values allowed to develop an affordable preliminary regression model to predict long-term cognitive status. So, some lipid peroxidation biomarkers would deserve consideration as useful progression AD biomarkers. The developed prediction model would constitute an important minimally invasive approach in AD personalized prognosis and perhaps could have some interest also in experimental treatments evaluation.

Assessment of the microbiological quality of pattern minas cheese commercialized in Uberlândia and Patos de Minas, Minas Gerais / Avaliação microbiológica de queijo minas padrão comercializado em Uberlândia e Patos de Minas, Minas Gerais

Pattern minas cheese is a product developed with pasteurized milk, fermented with mesophilic cultures, and with the final addition of rennet. This cheese undergoes an artisanal maturation process and possesses a firm shell of yellowish color and striking and acidic flavor. Our study objective was to evaluate the microbiological quality of pattern minas cheese. We collected 40 samples from two micro regions (Uberlândia and Patos de Minas) of the Triângulo Mineiro and Alto Paranaíba mesor regions of the State of Minas Gerais, Brazil. The microbiological test results were recorded as counts of enterobacteria, Escherichia coli, coliforms at 35°C, coagulase-positive Staphylococcus and Salmonella spp. In the Patos de Minas micro region, the results were 45%, 35%, 20%, and 20% higher than 103 CFU/g for the counts of enterobacteria, Escherichia coli, coliforms at 35°C, and Staphylococcus coagulase-positive, respectively. Five percent of the analyzed samples were positive for Salmonella spp. in the Uberlândia micro region. Based on the findings of the microbiota in the cheese analyzed from the micro regions (Uberlândia and Patos de Minas), we concluded that the hygiene conditions in the manufacturing, handling, transport, and storage stages were precarious, requiring the implementation of Good Manufacturing Practices (GMP) systems, including Hazard Analysis and Critical Control Points (HACCP).(AU)

O queijo minas padrão é um produto elaborado com leite pasteurizado, fermentado com culturas mesófilas e adição de coalho. Esse queijo passa por um processo de maturação artesanal, possui uma casca firme de cor amarelada e sabor ácido. O presente trabalho avaliou a qualidade microbiológica de queijo minas padrão comercializado em duas microrregiões (Uberlândia e Patos de Minas) da mesorregião do Triângulo Mineiro e Alto Paranaíba do estado de Minas Gerais, Brasil. Foram examinadas 40 amostras de queijo. Os ensaios microbiológicos foram contagens de enterobactérias, Escherichia coli, coliformes a 35 oC, Staphylococcus coagulase positiva e pesquisa de Salmonella spp. Na microrregião de Patos de Minas, os resultados foram de 45%, 35%, 20% e 20% superiores a 103 CFU/g para as contagens de enterobactérias, Escherichia coli, coliformes a 35oC e Staphylococcus coagulase positiva, respectivamente. Cinco por cento das amostras analisadas foram positivas à pesquisa de Salmonella spp. Considerando a microrregião analisada (Uberlândia e Patos de Minas), a conclusão obtida foi que na região estudada, as condições de higiene nas etapas de fabricação, manuseio, transporte e armazenamento do queijo minas padrão são precárias, sendo necessária a implementação de sistemas de Boas Práticas de Fabricação (GMP), incluindo Análise de Perigos e Pontos Críticos de Controle (HACCP).(AU)

Associations of social, physical, and financial factors with diet quality among older, community-dwelling women.

OBJECTIVE: This analysis examined whether specific social, physical, and financial factors were associated with diet quality among older, community-dwelling women. METHODS: This cross-sectional analysis was conducted in a subset of 6,094 community-dwelling Women's Health Initiative participants who completed a food frequency questionnaire, administered from 2012 to 2013, and a self-administered supplemental questionnaire, administered approximately 1 year later. The supplemental questionnaire included five questions assessing social, physical, and financial factors related to eating. Diet quality was assessed with the Healthy Eating Index-2010 (HEI-2010; range of 0-100; higher score indicates a higher quality diet). The total HEI-2010 score was calculated by summing individual scores representing the intake of nine adequacy components (beneficial food groups) and three moderation components (food groups to limit). Associations of responses to the five questions on the supplemental questionnaire with HEI-2010 scores were examined with multiple linear regression, adjusting for relevant covariates. RESULTS: Mean ±â€Šstandard deviation age of participants was 78.8 ±â€Š6.7 years. Reporting eating fewer than two meals per day, having dental or other mouth problems causing problems with eating, and not always being able to shop, cook, or feed oneself were associated with statistically significantly lower HEI-2010 scores, compared with those not reporting these issues, after multivariable adjustment: 5.37, 2.98, and 2.39 lower scores, respectively (all P values <0.0001). Reporting eating alone most of the time and not always having enough money to buy food were not associated with HEI-2010 scores. CONCLUSIONS: Among older, community-dwelling women, eating fewer than two meals per day, dental and other mouth problems, and diminished ability to shop for food, prepare meals, and feed oneself were associated with lower diet quality. These are potential targets for interventions to improve diet quality in older women. : Video Summary:http://links.lww.com/MENO/A561.

Optimism may moderate screening mammogram frequency in Medicare: A longitudinal study.

Higher trait optimism and/or lower cynical hostility are associated with healthier behaviors and lower risk of morbidity and mortality, yet their association with health care utilization has been understudied. Whether these psychological attitudes are associated with breast cancer screening behavior is unknown. To assess the association of optimism and cynical hostility with screening mammography in older women and whether sociodemographic factors acted as mediators of these relationships, we used Women's Health Initiative (WHI) observational cohort survey data linked to Medicare claims. The sample includes WHI participants without history of breast cancer who were enrolled in Medicare Parts A and B for ≥2 years from 2005-2010, and who completed WHI baseline attitudinal questionnaires (n = 48,291). We used survival modeling to examine whether screening frequency varied by psychological attitudes (measured at study baseline) after adjusting for sociodemographic characteristics, health conditions, and healthcare-related variables. Psychological attitudes included trait optimism (Life Orientation Test-Revised) and cynical hostility (Cook Medley subscale), which were self-reported at study baseline. Sociodemographic, health conditions, and healthcare variables were self-reported at baseline and updated through 2005 as available. Contrary to our hypotheses, repeated events survival models showed that women with the lowest optimism scores (i.e., more pessimistic tendencies) received 5% more frequent screenings after complete covariate adjustment (p < .01) compared to the most optimistic group, and showed no association between cynical hostility and frequency of screening mammograms. Sociodemographic factors did not appear to mediate the relationship between optimism and screenings. However, higher levels of education and higher levels of income were associated with more frequent screenings (both p < .01). We also found that results for optimism were primarily driven by women who were aged 75 or older after January 2009, when changes to clinical guidelines lead to uncertainty about risks and benefits of screening in this age group. The study demonstrated that lower optimism, higher education, and higher income were all associated with more frequent screening mammograms in this sample after repeated events survival modeling and covariate adjustment.

Understanding the relation between socioeconomic position and inflammation in post-menopausal women: education, income and occupational prestige.

Background: The role of occupational prestige, a direct measure of the perceived status of job and job holder, in inflammation is unknown. To contribute to understanding the pathways by which socioeconomic position (SEP) is associated with inflammation, we aimed to estimate the direct effects of education, income and occupational prestige on C-reactive protein (CRP) and to describe the relationship between these markers and CRP. Methods: The study was based on 2026 post-menopausal women enrolled in the Women's Health Initiative-Observational Study. Occupational prestige was determined by linking a text description of longest held occupation with a social status item from the Occupational Information Network. Path analysis was employed to estimate direct and mediated effects. Results: The study suggests that higher levels of education, income, and occupational prestige are associated with 8% (95% CI as percentage change -12, -4), 5% [95% CI (-8, -2) and 4% (95% CI - 7, -1)] lower levels of CRP, respectively. The inverse association between education and CRP was explained by the effect of education on income and occupational prestige. The effect of occupational prestige on CRP was independent of mediators in the model. Conclusions: The findings indicate that education may work to influence CRP primarily through increasing income and occupational prestige and provides evidence that occupational prestige captures a unique aspect of SEP.

[Social programs and reducing obesity in Peru: reflections from the research]. / Programas sociales y reducción de la obesidad en el Perú: reflexiones desde la investigación.

In recent decades, overweight or obesity have increased dramatically in middle- and low-income countries; a situation which consolidates chronic non-communicable diseases (NCD) as one of the leading causes of mortality and disability worldwide. Currently, half the people in Peru over the age of 15 years are overweight, and one fifth suffer from obesity. The situation is worsening and increasingly affects people in poverty, who frequently benefit from food supplement programs designed to combat food insecurity and malnutrition. There is an urgent worldwide need to find policies and programs that help fight the problem of obesity at the population level, a task that is still pending. In this article, we review the current epidemic of overweight and obesity in Peru and the world and its most significant consequences and causes, with an emphasis on access to and availability of foods. We describe the largest food supplement programs and synthesize the research on interventions in order to reflect on how their findings might help social programs work as a platform to reduce obesity and prevent NCD in Peru.

Programas sociales y reducción de la obesidad en el Perú: reflexiones desde la investigación / Social programs and reducing obesity in Peru: reflections from the research

RESUMEN En las últimas décadas, el sobrepeso y la obesidad han aumentado de forma acelerada en los países de ingresos medios y bajos, una situación que consolida a las enfermedades crónicas no transmisibles (ENT) como una de las más importantes causas de mortalidad y discapacidad a nivel global. Actualmente, uno de cada dos peruanos mayores de 15 años tiene exceso de peso y uno de cada cinco sufre de obesidad, una situación que está en continuo crecimiento y afecta cada vez más intensamente a los que viven en condiciones de pobreza, quienes, con frecuencia, son beneficiarios de programas de complementación alimentaria, dirigidos a enfrentar la inseguridad alimentaria y la desnutrición. Existe globalmente una urgente necesidad de encontrar políticas y programas que permitan enfrentar el problema de la obesidad a nivel poblacional, una tarea todavía pendiente. En este artículo revisamos la situación actual de la epidemia de sobrepeso y obesidad en el Perú y el mundo, sus consecuencias y determinantes más importantes, con énfasis en el acceso y disponibilidad de alimentos; describimos los programas de complementación alimentaria más importantes y sintetizamos información de algunas investigaciones e intervenciones para reflexionar sobre cómo sus hallazgos podrían servir para que los programas sociales sean una como plataforma para reducir la obesidad y prevenir las ENT en el Perú.

Influence of neighbourhood socioeconomic position on the transition to type II diabetes in older Mexican Americans: the Sacramento Area Longitudinal Study on Aging.

OBJECTIVE: To examine the influence of neighbourhood socioeconomic position (NSEP) on development of diabetes over time. DESIGN: A longitudinal cohort study. SETTING: The data reported were from the Sacramento Area Latino Study on Aging, a longitudinal study of the health of 1789 older Latinos. PARTICIPANTS: Community-dwelling older Mexican Americans residing in the Sacramento Metropolitan Statistical Area. MAIN OUTCOME: Multistate Markov regression were used to model transitions through four possible states over time: 1=normal; 2=pre-diabetic; 3=diabetic; and 4=death without diabetes. RESULTS: At baseline, nearly 50% were non-diabetic, 17.5% were pre-diabetic and nearly 33% were diabetic. At the end of follow-up, there were a total of 824 people with type 2 diabetes. In a fully adjusted MSM regression model, among non-diabetics, higher NSEP was not associated with a transition to pre-diabetes. Among non-diabetics, higher NSEP was associated with an increased risk of diabetes (HR=1.66, 95% CI 1.14 to 2.42) and decreased risk of death without diabetes (HR: 0.56, 95% CI 0.33 to 0.96). Among pre-diabetics, higher NSEP was significantly associated with a transition to non-diabetic status (HR: 1.22, 95% CI 0.99 to 1.50). Adjusting for BMI, age, education, physical activity, smoking, alcohol consumption, medical insurance and nativity did not affect this relationship. CONCLUSIONS: Our findings show that high NSEP poses higher risk of progression from normal to diabetes compared with a lower risk of death without diabetes. This work presents a possibility that these associations are modified by nativity or culture.

Correlates of Successful Aging in Racial and Ethnic Minority Women Age 80 Years and Older: Findings from the Women's Health Initiative.

BACKGROUND: Most research has focused on definitions and predictors of successful aging. However, racial/ethnic minorities are often under represented in this research. Given that the U.S. population is aging and becoming more racially diverse, we examined correlates of "successful aging," as defined by physical functioning and overall quality of life (QOL), among racial/ethnic minority women aged 80 years and older in the Women's Health Initiative. METHODS: Participants included 1,924 racial/ethnic minority women (African Americans, Asian/Pacific Islanders, Hispanic/Latinos, and American Indian/Alaskan Natives) 80 years of age and older who are enrolled in the Women's Health Initiative and have physical functioning data after turning 80 years of age. Analysis of covariance was used to examine between and within group differences in physical functioning and selfrated overall QOL for African Americans, Asian/Pacific Islanders, and Hispanic/Latinos. RESULTS: We found no significant differences in physical functioning between racial/ethnic minority groups in adjusted analyses. However, overall QOL was significantly different between racial/ethnic minority groups. Age, recreational physical activity, and overall selfrated health were independent correlates of physical functioning across racial/ethnic minority groups, whereas overall selfrated health was the only consistent correlate of overall QOL across the minority groups for the within minority group comparisons. CONCLUSIONS: Between racial/ethnic minority group differences in physical functioning are largely explained by demographic, psychosocial, behavioral, and health-related variables. We found statistically significant differences in selfrated overall QOL between racial/ethnic minority groups.

Care Indicators in Patients With Atrial Fibrillation: Assessment of Sex Differences and Management of Clinical Problems.

INTRODUCTION AND OBJECTIVES: To assess sex differences and the management of clinical problems in patients with atrial fibrillation through the use of care indicators. METHODS: Over a 5-month period, the study included all consecutive patients attended in the cardiology outpatient clinics of 2 tertiary hospitals with an atrial fibrillation episode or a clinical process due to atrial fibrillation. RESULTS: A total of 533 patients were included (56.5% women; mean age, 70.5 ± 12.2 years), of whom 24.3% were younger than 65 years. Women had significantly more clinical problems and a higher stroke risk: CHADS2 (congestive heart failure, hypertension, age, diabetes, stroke [doubled]) (1.8 ± 1.2 vs 1.5 ± 1.1; P = .001) and CHA2DS2-VASc (congestive heart failure, hypertension, age ≥ 75 [doubled], diabetes, stroke [doubled]-vascular disease and sex category [female]) (3.7 ± 1.4 vs 2.2 ± 1.4; P = .0001). Referrals to the cardiology department were appropriate in 94% of the patients, the referral source was primary care or other hospital services in 53.8%, and echocardiography was performed or recommended in 93.4%. Treatment (antiarrhythmics and anticoagulants) was administered according to guideline recommendations. In the previous 3 months, the Rosendaal index was 48.4 ± 37.4. CONCLUSIONS: One in every 4 patients seeking care for problems associated with atrial fibrillation are young; women have more clinical problems and seek care more frequently than men. Patients are correctly referred to the cardiology department and most are not referred from the emergency department. Echocardiography and antiarrhythmic and anticoagulant therapy were provided according to the recommendations of clinical practice guidelines. Vitamin K antagonists for anticoagulation therapy are underused.

Cross-sectional and longitudinal risk of physical impairment in a cohort of postmenopausal women who experience physical and verbal abuse.

BACKGROUND: Exposure to interpersonal violence, namely verbal and physical abuse, is a highly prevalent threat to women's health and well-being. Among older, post-menopausal women, several researchers have characterized a possible bi-directional relationship of abuse exposure and diminished physical functioning. However, studies that prospectively examine the relationship between interpersonal abuse exposure and physical functioning across multiple years of observation are lacking. To address this literature gap, we prospectively evaluate the association between abuse exposure and physical functioning in a large, national cohort of post-menopausal women across 12 years of follow-up observation. METHODS: Multivariable logistic regression was used to measure the adjusted association between experiencing abuse and physical function score at baseline in 154,902 Women's Health Initiative (WHI) participants. Multilevel modeling, where the trajectories of decline in physical function were modeled as a function of time-varying abuse exposure, was used to evaluate the contribution of abuse to trajectories of physical function scores over time. RESULT: Abuse was prevalent among WHI participants, with 11 % of our study population reporting baseline exposure. Verbal abuse was the most commonly reported abuse type (10 %), followed by combined physical and verbal abuse (1 %), followed by physical abuse in the absence of verbal abuse (0.2 %). Abuse exposure (all types) was associated with diminished physical functioning, with women exposed to combined physical and verbal abuse presenting baseline physical functioning scores consistent with non-abused women 20 years senior. Results did not reveal a differential rate of decline over time in physical functioning based on abuse exposure. CONCLUSIONS: Taken together, our findings suggest a need for increased awareness of the prevalence of abuse exposure among postmenopausal women; they also underscore the importance of clinician's vigilance in their efforts toward the prevention, early detection and effective intervention with abuse exposure, including verbal abuse exposure, in post-menopausal women. Given our findings related to abuse exposure and women's diminished physical functioning at WHI baseline, our work illuminates a need for further study, particularly the investigation of this association in younger, pre-menopausal women so that the temporal ordering if this relationship may be better understood.
