Selected AbstractsThe Myocardial Performance Index in Patients with Aortic StenosisECHOCARDIOGRAPHY, Issue 4 2002Jude A. Mugerwa M.D. Objectives: This study was designed to determine the effect of chronic afterload on a Doppler-derived myocardial performance index (MPI) combining both systolic and diastolic left ventricular dysfunction. Methods: The study included 36 patients with a diagnosis of aortic stenosis and 36 normal subjects. Doppler-derived myocardial performance index (MPI), defined as the sum of the isovolumic contraction time and isovolumic relaxation time divided by ejection time, was measured from the mitral valve inflow and left ventricular outflow velocity patterns and was then related to the aortic valve area, valve gradient, and other echocardiographic variables. Results: The values of the Doppler-derived MPI in the patients with aortic stenosis were significantly higher than those in the controls (0.54 ± 0.20 vs 0.38 ± 0.04, respectively; P < 0.001). Transmitral deceleration time and the E/A ratio (r = 0.47 and r = 0.35, respectively; P < 0.05) were significant univariate correlates, and mitral deceleration time was the only significant correlate of MPI. However the index did not correlate with aortic valve area, peak and mean valve gradients, left ventricular mass, or age. Conclusions: Doppler-derived MPI reflects severity of global left ventricular dysfunction in patients with aortic stenosis and may be of clinical value in this patient population. [source] Modelling space use and dispersal of mammals in real landscapes: a tool for conservationJOURNAL OF BIOGEOGRAPHY, Issue 4 2003David W. Macdonald Abstract Aim To explore the usefulness of Spatially Explicit Population Models (SEPMs), incorporating dispersal, as tools for animal conservation, as illustrated by the contrasting cases of four British mammals. Methods For each of the four species (American mink, Mustela vison, pine marten, Martes martes, dormouse, Muscardinus avellanarius and water vole, Arvicola terrestris) a spatial dynamics model was developed based on an integrated geographical information system (GIS) population model that linked space use to the incidence of the species. Each model had, first, a GIS, which stored environmental, habitat and animal population information, and secondly, an individual-based population dynamics module, which simulated home range formation, individual life histories and dispersal within the GIS-held landscape. Results The four models illustrated different interactions between species life-history variables and the landscape, particularly with respect to dispersal. As water voles and dormice occupy home ranges that are small relative to blocks of their habitat, they were most effectively modelled in terms of the dynamics of local populations within habitat blocks but linked by dispersal. In contrast, because the home ranges of American mink and pine marten are large relative to blocks of habitat, they were best modelled as individuals moving through a landscape of more or less useful patches of habitat. For the water vole, the most significant predictors of population size were the carrying capacity of each habitat and the annual number of litters. For the dormouse, the likelihood of catastrophe and the upper limit to dispersal movement were the key variables determining persistence. Adult mortality and home-range size were the only significant partial correlates of total population size for the American mink. Adult mortality was also a significant correlate of total population size in the pine marten, as were litter size and juvenile mortality. In neither the marten nor the mink was dispersal distance a significant factor in determining their persistence in the landscape. Main conclusions At a landscape scale it is difficult to measure animal distributions directly and yet conservation planning often necessitates knowledge of where, and in what numbers, animals are found, and how their distributions will be affected by interventions. SEPMs offer a useful tool for predicting this, and for refining conservation plans before irreversible decisions are taken in practice. [source] Appraisal of the cancer experience by older long-term survivorsPSYCHO-ONCOLOGY, Issue 3 2003Karen F. Bowman Cancer survivorship is best viewed as a process that continues across the life span. Appraisals of cancer change over time and may not be explicit until long after treatment completion. The current study, using the Lazarus and Folkman (1984) stress-appraisal-coping framework, explored factors related to both a stressful and an irrelevant appraisal of the cancer experience by older long-term survivors. Hierarchical regression analysis investigated the individual and cumulative effects of person factors (survivors' demographic characteristics, beliefs about the effect of cancer on family members) and situation factors (characteristics of cancer) on survivors' appraisals that cancer was a stressful life event. The strongest correlates of the stress appraisal were person factors. A more stressful appraisal was associated with: (1) the belief that diagnosis/treatment caused greater family distress, (2) being younger, and (3) being White. The irrelevant appraisal had a marginally significant correlate in bivariate analysis and was not included in regression analysis. Implications for health-care professionals and patient/family interventions are discussed. Copyright © 2002 John Wiley & Sons, Ltd.

Aims., The objective was to examine the extent to which women's likelihood or consistency of partnered orgasm is associated with duration of foreplay, duration of penile,vaginal intercourse, and age. Methods., In a representative sample of the Czech population, 2,360 women reported their consistency of orgasm with a partner (from "never" to "almost every time"), and estimates of their typical durations of foreplay and of penile,vaginal intercourse. Main Outcome Measures., The association of consistency of partnered orgasm with typical durations of both foreplay and penile,vaginal intercourse. Results., In univariate analyses, consistency of partnered orgasm was more associated with penile,vaginal intercourse duration than with foreplay duration (consistency also correlated negatively with age). In multivariate analysis, foreplay ceased to be a significant correlate of partnered orgasm consistency (the exclusion of respondents reporting a penile,vaginal intercourse duration of 1 minute or less did not alter the results). Conclusions., When both sexual activity categories are examined in tandem on a population level, women's likelihood or consistency of partnered orgasm is associated with penile,vaginal intercourse duration, but not with foreplay duration. In contrast to the assumptions of many sex therapists and educators, more attention should be given to improve the quality and duration of penile,vaginal intercourse rather than foreplay.

[source] Correlates of Coparenting During Infancy,FAMILY RELATIONS, Issue 3 2005Eric W. Lindsey Abstract: This study examined family characteristics associated with the coparenting behavior of 60 parents with an 11- to 15-month-old infant (30 boys, 30 girls) during a structured triadic play session. Mothers reported on family demographics, social support, and child temperament. Both parents reported on their self-esteem and childrearing beliefs. Fathers displayed more supportive coparenting behavior than mothers. Mothers' intrusive coparenting behavior differed based on the number of children, parent's employment status, and child gender. Social support, parental self-esteem, and child temperament were significant correlates of individual coparenting behavior. Results are discussed in terms of their implications for family theory and family practice. [source] Prevalence and correlates of eating disorders in Latinos in the United StatesINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue S3 2007Margarita Alegria PhD Abstract Objective: To present national estimates and correlates of lifetime and 12-month DSM-IV eating disorders for Latinos. Method: Data come from the National Latino and Asian American Study (NLAAS), a national epidemiological household survey of Latinos in the United States. Results: Latinos have elevated rates of any binge eating and binge eating disorder but low prevalence of anorexia nervosa and bulimia nervosa. The US born and those living a greater percentage of their lifetime in the US evidenced higher risk for certain eating disorders while severe obesity and low levels of education were significant correlates. Rates of treatment utilization were exceedingly low. Conclusion: Standard eating disorder criteria may not be appropriate for understanding psychological morbidity of eating disorders for Latinos, particularly less acculturated Latinos, due to cultural differences in the presentation of eating disorder symptoms. Criteria for disturbed eating patterns that are more reflective of the illness experience of Latinos should be developed. © 2007 by Wiley Periodicals, Inc. [source] Gender, kinship and caregiver burden: the case of community-dwelling memory impaired seniorsINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 8 2003Neale R. Chumbler Abstract Background This study examined whether there were gender and kinship (spouse, child, more distant relative) differences in caregiver burden. It further examined the constellation of gender and kinship by examining whether adult daughter caregivers experienced greater burden compared to wives, husbands, sons, and other more distant relatives. Methods The sample consisted of 305 family caregivers of memory-impaired individuals who were age 70 years or older and resided in non-institutional settings in Arkansas. A cross-sectional design was employed using validated measures to assess both the memory-impaired elders' and family caregivers' self-reported physical and memory status. Results After controlling for the age and health status characteristics of the memory-impaired elder, sociodemographic and health status characteristics of the family caregiver, and the caregiver coping response (measured by the sense of coherence), multiple regression analyses found kinship, but not gender differences in caregiver burden. Adult children experienced more caregiver burden than more distant relatives. There were no significant differences in caregiver burden between adult children and spouses. Adult daughters had greater caregiver burden scores compared to more distant relatives, but had comparable scores to wives, sons, and husbands. Other significant correlates of burden included caregiver personal characteristics (age and ethnicity) and the sense of coherence. Conclusions The study discusses the practice implications of adult children and adult daughters' propensity to suffer burden when caring for their memory-impaired parents living in the community. It also discusses the relevance of caregiver personal characteristics and the sense of coherence as correlates of burden. Copyright © 2003 John Wiley & Sons, Ltd. [source] A validation study of the Cross-Cultural Adaptability InventoryINTERNATIONAL JOURNAL OF TRAINING AND DEVELOPMENT, Issue 2 2010Nhung T. Nguyen Despite the claims made about the effectiveness of cross-cultural training programs, few studies have examined the reliability and validity of the instruments used in these training programs. In this study, the authors examined the factor structure of the Cross-Cultural Adaptability Inventory (CCAI) via a confirmatory factor analytic approach. A series of confirmatory factor analytic models was tested and applied at the item level to both the CCAI and Goldberg's Big Five Inventory. A confirmatory factor analysis (CFA) model in which a method factor was estimated fits the data significantly better than a model without such a method effect. Further, the method factor suppressed substantive relationships such that the two CCAI factors of Emotional Resilience and Personal Autonomy became significant correlates with self-reported number of international job assignments after accounting for method variance. Implications for research and practice are discussed. [source] Do cultural factors predict mammography behaviour among Korean immigrants in the USA?JOURNAL OF ADVANCED NURSING, Issue 12 2009Hanju Lee Abstract Title.,Do cultural factors predict mammography behaviour among Korean immigrants in the USA? Aim., This paper is a report of a study of the correlates of mammogram use among Korean American women. Background., Despite the increasing incidence of and mortality from breast cancer, Asian women in the United States of America report consistently low rates of mammography screening. A number of health beliefs and sociodemographic characteristics have been associated with mammogram participation among these women. However, studies systematically investigating cultural factors in relation to mammogram experience have been scarce. Methods., We measured screening-related health beliefs, modesty and use of Eastern medicine in 100 Korean American women in 2006. Hierarchical logistic regression was used to examine the unique contribution of the study variables, after accounting for sociodemographic characteristics. Findings., Only 51% reported past mammogram use. Korean American women who had previously had mammograms were statistically significantly older and had higher perceived benefit scores than those who had not. Perceived benefits (odds ratio = 6·3, 95% confidence interval = 2·12, 18·76) and breast cancer susceptibility (odds ratio = 3·18, 95% confidence interval = 1·06, 9·59) were statistically significant correlates of mammography experience, whereas cultural factors did not correlate. Post hoc analysis showed that for women with some or good English skills, cultural factors statistically significantly correlated with health beliefs and breast cancer knowledge (P < 0·05). Conclusion., Nurses should consider the inclusion in culturally tailored interventions of more targeted outreach and healthcare system navigation assistance for promoting mammography screening in Korean American women. Further research is needed to unravel the interplay between acculturation, cultural factors and health beliefs related to cancer screening behaviours of Korean American women. [source] Korean mothers' psychosocial adjustment to their children's cancerJOURNAL OF ADVANCED NURSING, Issue 5 2003Hae-Ra Han PhD RN Background., During the course of adjustment to their child's illness and medical treatment, parents of children with cancer may experience numerous challenges and difficulties. Although parental adjustment has been a research topic for many years, little research has been conducted among families in different cultures and countries. Aim., To identify factors that influence maternal psychosocial adjustment to childhood cancer using a new cultural group: Korean. Methods., A sample of 200 Korean mothers of children with cancer was included in the study. Guided by the double ABCX model of family adjustment and adaptation, a series of variables (i.e. maternal stress, coping, social support and selected illness-related and demographic questions) were examined for their relationships with maternal psychosocial adjustment to childhood cancer. Results., Using a hierarchical multiple regression, we found perceived level of stress, coping, social support, and time since diagnosis to be significant correlates of maternal psychosocial adjustment. Stress accounted for most (50%) of the total variance explained (56%) in maternal adjustment. Conclusion., The results suggest that the stress-coping framework may be appropriate in explaining maternal responses to childhood cancer across cultures. [source] Physical Exercise in Chinese Older Adults: A Transtheoretical Model,JOURNAL OF APPLIED BIOBEHAVIORAL RESEARCH, Issue 2 2006Kee-Lee Chou Physical exercise has a positive impact on physical and mental health among older adults. This study identifies significant correlates of exercise behavior among Hong Kong Chinese older adults under the transtheoretical model. The data came from a survey of a representative community sample of 425 elderly respondents in Hong Kong. Using multiple regression models, the authors found that perceived benefits of exercise and self-efficacy for exercise were related significantly to exercise behavior, and their effects on exercise were mediated completely through the stages of changes in exercise. Although perceived barriers to exercise are significantly and negatively associated with exercise behavior, this relationship disappeared in multiple regression analysis after controlling demographic and several health-related variables. Findings suggest that perceived benefits and self-efficacy on exercise should be strengthened to motivate older adults to engage in a more active lifestyle. [source] Prosper study of evidence-based intervention implementation quality by community,university partnershipsJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 8 2007Richard Spoth This study examined a community,university partnership model for sustained, high-quality implementation of evidence-based interventions. In the context of a randomized study, it assessed whether implementation quality for both family-focused and school-based universal interventions could be achieved and maintained through community,university partnerships. It also conducted exploratory analyses of factors influencing implementation quality. Results revealed uniformly high rates of both implementation adherence,averaging over 90%,and of other indicators of implementation quality for both family-focused and school-based interventions. Moreover, implementation quality was sustained across two cohorts. Exploratory analyses failed to reveal any significant correlates for family-intervention implementation quality, but did show that some team and instructor characteristics were associated with school-based implementation quality. © 2007 Wiley Periodicals, Inc.

[source] Explaining agricultural productivity growth: an international perspectiveAGRICULTURAL ECONOMICS, Issue 1 2010Derek Headey Labor productivity; Multi-output distance function; Total factor productivity Abstract This article presents multi-output, multi-input total factor productivity (TFP) growth rates in agriculture for 88 countries over the 1970,2001 period, estimated with both stochastic frontier analysis (SFA) and the more commonly employed data envelopment analysis (DEA). We find results with SFA to be more plausible than with DEA, and use them to analyze trends across countries and the determinants of TFP growth in developing countries. The central finding is that policy and institutional variables, including public agricultural expenditure and proagricultural price policy reforms, are significant correlates of TFP growth. The most significant geographic correlate of TFP growth is distance to the nearest OECD country. [source] Salient Environmental and Perceptual Correlates of Current and Established Smoking for 2 Representative Cohorts of Indiana AdolescentsJOURNAL OF SCHOOL HEALTH, Issue 3 2009Dong-Chul Seo PhD ABSTRACT PURPOSE:, A secondary analysis of 2000 and 2004 Indiana Youth Tobacco Survey (IYTS) data was conducted to investigate salient environmental and perceptual correlates of adolescents' current and established smoking while controlling for demographic variables such as gender, grade, and race/ethnicity and to compare the pattern of significant correlates between the years. METHODS:, The IYTS was an anonymous school-based survey regarding tobacco use; familiarity with pro- and anti-tobacco media messages; exposure to environmental tobacco smoke (ETS); minors' access to tobacco products; and general knowledge, attitudes, and beliefs about tobacco. In 2000, a representative sample of 1416 public high school students in grades 9-12 and 1516 public middle school students in grades 6-8 (71.44% and 72.53% response rates, respectively) were surveyed. In 2004, 3433 public high school students and 1990 public middle school students (63.04% and 65.44 % response rates, respectively) were surveyed. RESULTS:, Significant predictors of adolescents' current and established smoking habits included exposure to ETS either in homes or in cars, exposure to pro-tobacco messages, perceived benefit of smoking, and perceived peer acceptance of smoking. The influence of exposure to pro-tobacco messages greatly outweighed exposure to any anti-tobacco messages. CONCLUSIONS:, The findings of this study warrant that more efforts and resources be placed on preventing youth from being exposed to ETS, and to control pro-tobacco marketing and improve the tobacco counter-marketing messages. The perceived benefits of smoking found here indicate that smoking for relaxation and weight control may be major influencing factors on adolescent smoking. [source] Psychological distress in long-term survivors of solid tumors diagnosed in childhood: A report from the childhood cancer survivor studyPEDIATRIC BLOOD & CANCER, Issue 1 2007Brad J. Zebrack PhD Abstract Purpose To evaluate and compare psychological distress in long-term survivors of solid tumors diagnosed in childhood and their siblings, and to identify significant correlates of psychological distress. Procedure Adult survivors (2,778) of solid tumors diagnosed in childhood and 2,925 siblings completed a long-term follow-up questionnaire assessing symptoms associated with depression, somatization, and anxiety, as well as demographic, health, and medical information. Results Overall, a large majority of siblings and survivors reported few, if any, symptoms of psychological distress. In the aggregate, solid tumor cancer survivors reported significantly higher levels of global distress as measured by the Brief Symptom Inventory (BSI-18), as well as higher levels of somatization and anxiety, when compared to siblings. However, when compared to population norms, both survivors and siblings reported lower levels of global and dimensional distress. Female gender, lower educational and income attainment, perceived poor health status and reports of current health problems all were associated with reporting psychological distress symptoms for both survivors and siblings. Among survivors, having a limb amputation was associated with reporting fewer symptoms of global and dimensional distress. Conclusion Poor health status, low levels of income, education, and employment appear to be predictors of distress for survivors of solid tumors. Thus, interventions that promote health and facilitate educational advancement, income attainment and social interaction to minimize isolation and maximize social support may reduce psychological distress and promote quality of life for childhood cancer survivors.

Abstract BACKGROUND: Evidence suggests that colorectal cancer (CRC) screening reduces disease-specific mortality, whereas the utility of prostate cancer screening remains uncertain. However, adherence rates for prostate cancer screening and CRC screening are very similar, with population-based studies showing that approximately 50% of eligible US men are adherent to both tests. Among men scheduled to participate in a free prostate cancer screening program, the authors assessed the rates and correlates of CRC screening to determine the utility of this setting for addressing CRC screening nonadherence. METHODS: Participants (N = 331) were 50 to 70 years old with no history of prostate cancer or CRC. Men registered for free prostate cancer screening and completed a telephone interview 1 to 2 weeks before undergoing prostate cancer screening. RESULTS: One half of the participants who underwent free prostate cancer screening were eligible for but nonadherent to CRC screening. Importantly, 76% of the men who were nonadherent to CRC screening had a regular physician and/or health insurance, suggesting that CRC screening adherence was feasible in this group. Furthermore, multivariate analyses indicated that the only significant correlates of CRC screening adherence were having a regular physician, health insurance, and a history of prostate cancer screening. CONCLUSIONS: Free prostate cancer screening programs may provide a teachable moment to increase CRC screening among men who may not have the usual systemic barriers to CRC screening, at a time when they may be very receptive to cancer screening messages. In the United States, a large number of men participate in annual free prostate cancer screening programs and represent an easily accessible and untapped group that can benefit from interventions to increase CRC screening rates.
