Association between exercise-induced change in body composition and change in cardiometabolic risk factors in postmenopausal South Asian women.

The South Asian population suffers from a high prevalence of type 2 diabetes and cardiovascular disease (CVD). A unique obesity phenotype of elevated visceral adipose tissue (VAT) is associated with CVD risk among South Asians. Exercise-induced reduction in VAT and body fat is an effective mechanism to improve cardiometabolic risk factors but this has not been shown in South Asians. Whether exercise-induced changes in measurements such as waist circumference (WC) are independently related to changes in cardiometabolic risk factors in South Asians is unknown. Multi-slice computed tomography scanning was used to assess VAT, cardiometabolic risk factors through a fasting blood sample, and body fat using dual-energy X-ray absorptiometry. Forty- nine postmenopausal South Asian women who participated in two 12-week aerobic exercise programs were included. Bivariate correlations were used to assess associations between change in cardiometabolic risk factors and change in body composition. Regression analyses were conducted with change in glucose, insulin, and homeostatic model assessment of insulin resistance (HOMA-IR) as dependent variables and change in body composition as independent variables of interest. There were significant associations between changes in fasting insulin, glucose, and HOMA-IR with change in VAT. The association between change in VAT and these cardiometabolic risk factors was independent of change in other body composition variables of interest. South Asian women should be encouraged to engage in aerobic activity to reduce their risk of type 2 diabetes and CVD, and physicians should be aware of improvements in glucose regulation with exercise training not observed through reductions in WC.

Effectiveness of Exercise on Visceral Adipose Tissue in Older South Asian Women.

INTRODUCTION: Individuals of South Asian (SA) origin have a greater risk for type 2 diabetes and cardiovascular disease than other ethnic populations. This increased risk is in part explained by the unique obesity phenotype of elevated visceral adipose tissue (VAT) among this population. Aerobic exercise in Europeans is effective at reducing VAT, but this has not been studied in SA, who have some of the lowest levels of physical activity in the world. Therefore, the purpose of this study was to determine whether exercise can reduce VAT given the unique obesity phenotype and associated disease risk in the SA population. METHODS: A total of 75 physically inactive, postmenopausal SA women were randomized to either culturally based (Bhangra dance), standard (gym-based), or control (nonexercise) program for 12-wk. The primary outcome was change in VAT. RESULTS: The average attendance in the culturally based and standard program was 78% ± 33% and 67% ± 25%, respectively. After an intention-to-treat analysis, VAT was not significantly reduced in culturally based (-60 cm, 95% confidence interval [CI] = -172 to 54, P = 0.300) or standard (-98 cm, 95% CI = -216 to 21, P = 0.106) exercise compared with control after adjustment for baseline physical activity and age. In those participants who attended more than two-thirds of the exercise classes, VAT was significantly reduced compared with control (-109 cm, 95% CI = -204 to -13, P = 0.026). CONCLUSION: In intention-to-treat analysis VAT was not significantly reduced after 12 wk of either standard or culturally based exercise. However, attendance in both standard and culturally based exercise was high, and VAT was significantly reduced among SA women who adhered to these programs.

A review of equity issues in quantitative studies on health inequalities: the case of asthma in adults.

BACKGROUND: The term 'inequities' refers to avoidable differences rooted in injustice. This review examined whether or not, and how, quantitative studies identifying inequalities in risk factors and health service utilization for asthma explicitly addressed underlying inequities. Asthma was chosen because recent decades have seen strong increases in asthma prevalence in many international settings, and inequalities in risk factors and related outcomes. METHODS: A review was conducted of studies that identified social inequalities in asthma-related outcomes or health service use in adult populations. Data were extracted on use of equity terms (objective evidence), and discussion of equity issues without using the exact terms (subjective evidence). RESULTS: Of the 219 unique articles retrieved, 21 were eligible for inclusion. None used the terms equity/inequity. While all but one article traced at least partial pathways to inequity, only 52% proposed any intervention and 55% of these interventions focused exclusively on the more proximal, clinical level. CONCLUSIONS: Without more in-depth and systematic examination of inequities underlying asthma prevalence, quantitative studies may fail to provide the evidence required to inform equity-oriented interventions to address underlying circumstances restricting opportunities for health.

Complementary and alternative therapy (CAT) use and highly active antiretroviral therapy (HAART): current evidence in the literature, 2000-2009.

AIM AND OBJECTIVE: To determine current evidence about the use of complementary and alternative medicine in the context of highly active antiretroviral therapy. The following objectives included identifying the risks and benefits of using complementary and alternative medicine when living with the human immunodeficiency virus (HIV) and taking such medications. BACKGROUND: In Canada and the USA, HIV/AIDS service organisations recognise that people affected or infected by HIV are increasingly choosing to use complementary and alternative medicine to cope with this disease. These same organisations advocate for increased access to complementary and alternative medicine and more information about the safe use of complementary and alternative medicine to make informed decisions. Based on the increased integral use of complementary and alternative medicine and conventional medicine in Canada and the USA, the literature review was limited to these two countries. DESIGN: Systematic review. METHOD: Available full-text abstracts published in English from 2000-2009 were retrieved by electronic searches of selected databases, including the websites of Health Canada and American National Center for Complementary and Alternate Medicine (NCCAM). Forty studies were examined and were categorised by referring to the NCCAM (2007) four types of complementary and alternative medicine. RESULTS: Insufficient evidence exists to support the use of a particular complementary and alternate therapy to enhance the management of HIV disease. CONCLUSION: Decisions about using complementary and alternative medicine in conjunction with highly active antiretroviral therapy are often poorly informed. Safety risks and potential drug interactions are frequently ignored as people who use highly active antiretroviral therapy prefer to focus on the physical and mental benefits of using selected complementary and alternate therapies to promote their quality of life. RELEVANCE TO CLINICAL PRACTICE: As life expectancy increases, from the use of highly active antiretroviral therapy, it is important for health professionals like nurses to be knowledgeable about the prevention, assessment and treatment of HIV symptoms and treatment side effects. Given the increased trend of using complementary and alternative medicine by the general population, it is also important to understand the appropriate use of complementary and alternative medicine for symptom management in HIV/AIDS care.

Perceptions of nursing: a study involving nurses, nursing students, patients and non-nursing students.

This paper describes a study of perceptions of nursing by nursing students, qualified nurses (United Kingdom and Spain), patients and non-nursing students. A survey method was used with a longitudinal panel element incorporating a 35-item version of the Nursing Dimensions Inventory translated into Spanish. Data were analysed using principal component analysis, congruence analysis, Mokken scaling, correlation, ANOVA, t-test and Cronbach's alpha. Patients may perceive nursing differently from nursing students, nurses (in the UK and Spain) and non-nurses. These findings are discussed in the context of nurse education and patient care.

Differences and similarities in the perception of caring between Spanish and UK nurses.

The aim of the present paper was to compare and contrast perceptions of caring in nursing between Spanish and UK nurses. There are no previous studies comparing directly the perceptions of caring across cultures in nursing. A survey method was used employing the 25-item Caring Dimensions Inventory. Data were Mokken scaled for comparison with data from a previous study and scores for common items on the 25-item Caring Dimension Inventory for Spanish and UK nurses were correlated. There were similarities and differences between Spanish and UK nurses' perceptions of caring: many similar items were incorporated into Mokken scales but the endorsement of items did not correlate. The present work demonstrates that it is possible to measure differences and similarities in perceptions of caring. The study design could be improved and such work could be valuable in cross-cultural work with nurses.

Elisions in the field of caring.

BACKGROUND: Contemporary research into caring in nursing was criticized in the pages of this journal by John Paley. He charged that the study of caring has not been advanced by research which, he reckoned, merely generates endless lists of terms to describe caring. He also argued that research in the field was largely flawed by confusion over the difference between things said about caring and the act of caring itself. THE PRESENT PAPER: We have analysed Paley's criticism. Essentially, he is criticizing the whole field of survey research. The scientific process is underpinned by the implicit understanding that any field moves forward cautiously. In the social sciences multiple perspectives enrich understanding of phenomena and often confirm previous perceptions. The lack of any alternative approach from Paley is evident. Examples from psychology, where seemingly endless lists of descriptors have led through rigorous concept and statistical analysis to genuinely useful psychological and clinical data, are expounded. In contrast to Paley's assertions, the study of caring in nursing to date has also produced information which is useful within nurse education and practice. CONCLUSION: There is no confusion concerning the things said about and the things done in the name of caring in our minds. We acknowledge that studying the actual phenomena of caring is difficult. However, in the absence of definitive descriptions of caring and precise methods to study it, the search for perfection has not paralysed action. Much has been learned about caring and much remains to be learned.
