Comparing trends in BMI and waist circumference

The nature of excess body weight may be changing over time to one of greater central adiposity. The aim of this study is to determine whether BMI and waist circumference (WC) are increasing proportionately among population subgroups and the range of bodyweight, and to examine the public health implications of the findings. Our data are from two cross-sectional surveys (the US National Health and Nutrition Examination Studies (NHANES) in 1988–1994 (NHANES III) and 2005–2006), from which we have used samples of 15,349 and 4,176 participants aged ≥20 years. Between 1988–1994 and 2005–2006 BMI increased by an average of 1.8 kg/m2 and WC by 4.7 cm (adjusted for sex, age, race-ethnicity, and education). The increase in WC was more than could be attributed simply to increases in BMI. This independent increase in WC (of on average, 0.9 cm) was consistent across the different BMI categories, sexes, education levels, and race-ethnicity groups. It occurred in younger but not older age groups. Overall in each BMI category, the prevalence of low-risk WC decreased and the prevalence of increased-risk or substantially increased-risk WC increased. These results suggest that the adverse health consequences associated with obesity may be increasingly underestimated by trends in BMI alone. Since WC is closely linked to adverse cardiovascular outcomes, it is important to know the prevailing trends in both of these parameters.

Cross-cultural differences in intimate partner violence and depression: a systematic review

Intimate partner violence (IPV) is a serious issue that affects women from many different cultures and contexts around the world and has serious mental health consequences such as depression. This review has systematically identified studies that have made cross-cultural comparisons of the relationship between IPV and depression. Parallel literature searches of PsychInfo, Academic Search Complete, and the Web of Knowledge were conducted for the period between January 1993 and August 2013 and reference lists of articles were scanned. Studies written in English that included a measure of depression and IPV and compared these constructs across women of different cultural groups were included. Eleven studies with a total of 33,716 participants met all the inclusion criteria. While all studies found a relationship between IPV and depression, six found that there were significant differences in IPV and depression between cultures and five indicated that there was no significant difference in this relationship between cultures. The reviewed literature suggests that where there are cross-cultural differences in the relationship between IPV and depression, factors such as help-seeking behavior, individual coping strategies, racism, identity as a wife, and cultural values are likely to play a mediating role. Future research should examine the unique contribution of these factors in alleviating depression associated with IPV within cultural groups

A cross-sectional study examining the extent of unwanted sexual attention and unhealthy intimate relationships among female university students

Issue addressed: Unwanted sexual attention and unhealthy intimate relationships have the potential to have serious negative health consequences. To date, there has been scant focus on these issues among university students in Australia. The aim of the current study was to describe the extent of unwanted sexual attention and unhealthy intimate relationships experienced in their lifetime by female university students aged 18–25 years.
Methods: A cross-sectional study was undertaken involving 465 female students aged 18–25 years. Students were recruited through one faculty within a Victorian university and invited to complete an anonymous online questionnaire.
Results: Sixty-seven per cent (n = 312) of female students reported experiencing unwanted sexual attention in their lifetime. The most common form of unwanted sexual attention was kissing or touching over clothes (98%; n = 306). Over 43% (n = 124) of the female students reported that the experience of unwanted sexual experience occurred after their protests were ignored. Thirty per cent (n = 135) of the female students reported experiencing at least one element of an unhealthy intimate relationship.
Conclusions: The high rates of unwanted sexual attention and unhealthy intimate relationships among female university students is of concern given the negative impact such events can have on individual’s physical, emotional and social well being.
So what?: Public health and health promotion action is required to prevent female students from experiencing unwanted sexual attention and unhealthy intimate relationships, and to address the negative health and well being consequences.

Health and mortality consequences of abdominal obesity : evidence from the AusDiab study

Objective: To provide an estimate of the morbidity and mortality resulting from abdominal overweight and obesity in the Australian population.

Design and setting: Prospective, national, population-based study (the Australian Diabetes, Obesity and Lifestyle [AusDiab] study).

Participants: 6072 men and women aged ≥ 25 years at study entry between May 1999 and December 2000, and aged ≤ 75 years, not pregnant and for whom there were waist circumference data at the follow-up survey between June 2004 and December 2005.

Main outcome measures: Incident health outcomes (type 2 diabetes, hypertension, dyslipidaemia, the metabolic syndrome and cardiovascular diseases) at 5 years and mortality at 8 years. Comparison of outcome measures between those classified as abdominally overweight or obese and those with a normal waist circumference at baseline, and across quintiles of waist circumference, and (for mortality only) waist-to-hip ratio.

Results: Abdominal obesity was associated with odds ratios of between 2 and 5 for incident type 2 diabetes, dyslipidaemia, hypertension and the metabolic syndrome. The risk of myocardial infarction among obese participants was similarly increased in men (hazard ratio [HR], 2.75; 95% CI, 1.08–7.03), but not women (HR, 1.43; 95% CI, 0.37–5.50). Abdominal obesity-related population attributable fractions for these outcomes ranged from 13% to 47%, and were highest for type 2 diabetes. No significant associations were observed between all-cause mortality and increasing quintiles of abdominal obesity.

Conclusions: Our findings confirm that abdominal obesity confers a considerably heightened risk for type 2 diabetes, the metabolic syndrome (as well as its components) and cardiovascular disease, and they provide important information that enables a more precise estimate of the burden of disease attributable to obesity in Australia.

Maternal dietary intake during pregnancy has longstanding consequences for the health of her offspring

Over the past 100 years, advances in pharmaceutical and medical technology have reduced the burden of communicable disease, and our appreciation of the mechanisms underlying the development of noncommunicable disease has broadened. During this time, a number of studies, both in humans and animal models, have highlighted the importance of maintaining an optimal diet during pregnancy. In particular, a number of studies support the hypothesis that suboptimal maternal protein and fat intake during pregnancy can have long-term effects on the growing fetus, and increase the likelihood of these offspring developing cardiovascular, renal, or metabolic diseases in adulthood. More recently, it has been shown that dietary intake of a number of micronutrients may offset or reverse the deleterious effects of macronutrient imbalance. Furthermore, maternal fat intake has also been identified as a major contributor to a healthy fetal environment, with a beneficial role for unsaturated fats during development as well as a beneficial impact on cell membrane physiology. Together these studies indicate that attempts to optimise maternal nutrition may prove to be an efficient and cost-effective strategy for preventing the development of cardiovascular, renal, or metabolic diseases.

Clinical nurses` response to an environment of health care reform and organizational restructuring

The aim of this paper is to provide an explanation for clinicians' undisputed acceptance of change. This will be performed by examining the process of organizational restructuring across three analytical levels – the macro, meso and micro; identifying the consequences of restructuring for clinical nurses' performance; and evaluating organizational restructuring using a micro-political theoretical framework.

Abating the consequences of managerialism on the forgotten employees : the issues of support, control, coping and pay

With the widespread and continuing adoption of managerialism in the public sector, ignoring the impact of change on employees could prevent managerialism from achieving its goals. Subsequently, this study investigates the efficacy of an augmented demand-control-support (D-C-S) model in predicting three of the key employee outcomes in the context of organizational change—psychological health, job satisfaction, and organizational commitment. Analyses of a survey of 207 employees in the Australian public sector, a sector that has undergone, and continues to undergo, substantial change toward managerialism, found that the augmented D-C-S model explained a significant proportion of the employee outcomes in the public sector context. The most important variables were work-based social support and job control. Coping style and perceptions of work conditions, such as pay, were also significant. The augmented D-C-S model provides a useful, proven tool for managers operating within the contemporary public sector.

The limits of medicine and the social consequences for sufferers of chronic fatigue syndrome

Chronic fatigue syndrome (CFS) appears to be made up of several clusters of illness categories acting alone or in tandem to cause the decline of health through; fatigue/exhaustion, sensitivity/allergies, pain, general muscle and joint pains, cognitive impairment and gastrointestinal problems. This study investigated how patients interpret, evaluate and respond to the complex and varied symptoms of chronic fatigue syndrome. Data were collected from persons with CFS using a survey (n=90) and an interview (n=45). The researchers investigated how chronic fatigue syndrome is diagnosed by medical practitioners, how the label of CFS is determined and the social consequences for the patient. The results confirm the limited ability of the biomedical paradigm to diagnose adequately and treat effectively 'socially constructed' and medically ambiguous illnesses like CFS. In the absence of a legitimated regime of medical treatment for CFS, a range of often expensive treatments are employed by CFS sufferers, from formal use of pharmaceutical drugs through to 'alternative' therapies, including herbal, vitamin, homeopathic, esoteric meditative techniques, spiritual healing and general counselling are taken in no particular order.

New money for mental health : will it make things better for rural and remote Australia?

New Australian government funding for the Better Outcomes in Mental Health Care initiative is a significant step forward for mental health, with general practitioners now able to offer direct referrals to psychologists, social workers, occupational therapists and Aboriginal health workers. Incentives for better teamwork between GPs and other mental health professionals have been introduced, but may have unintended consequences, including an exacerbation of workforce shortages in rural and remote areas. Possible solutions to these shortages include rural scholarships for students in the mental health professions; recruitment and retention of students coordinated by university departments of rural health; better access to continuing professional development; and federally funded rural positions and additional financial incentives for rural mental health practitioners.

Pursuit of the muscular ideal: Physical and psychological consequences and putative risk factors

Developing a lean muscular figure for the purposes of sports and/or appearance has become a central issue for males. Concern has been raised because the desire to develop such a body build may lead to the adoption of numerous health-threatening behaviors. Consequently, this review presents a comprehensive analysis of the physical and psychological consequences that result from the use of steroids (legal and illegal), ephedrine, and deleterious dieting strategies specific to males. Putative risk factors for these behaviors will be identified, and the clinical disorder associated with the extreme abuse of these behaviors, muscle dysmorphia, will be examined.

Gender and health promotion: A multisectoral policy approach

Women and men are different as regards their biology, the roles and responsibilities that society assigns to them and their position in the family and community. These factors have a great influence on causes, consequences and management of diseases and ill-health and on the efficacy of health promotion policies and programmes. This is confirmed by evidence on male–female differences in cause-specific mortality and morbidity and exposure to risk factors. Health promoting interventions aimed at ensuring safe and supportive environments, healthy living conditions and lifestyles, community involvement and participation, access to essential facilities and to social and health services need to address these differences between women and men, boys and girls in an equitable manner in order to be effective. The aim of this paper is to (i) demonstrate that health promotion policies that take women's and men's differential biological and social vulnerability to health risks and the unequal power relationships between the sexes into account are more likely to be successful and effective compared to policies that are not concerned with such differences, and (ii) discuss what is required to build a multisectoral policy response to gender inequities in health through health promotion and disease prevention. The requirements discussed in the paper include i) the establishment of joint commitment for policy within society through setting objectives related to gender equality and equity in health as well as health promotion, ii) an assessment and analysis of gender inequalities affecting health and determinants of health, iii) the actions needed to tackle the main determinants of those inequalities and iv) documentation and dissemination of effective and gender sensitive policy interventions to promote health. In the discussion of these key policy elements, we use illustrative examples of good practices from different countries around the world.

Pursuing HPE outcomes through health education

This chapter provides an analysis of how the contemporary curriculum operates in relation to pursuing Health and Physical Education (HPE) outcomes within health education and some of the intended and unintended consequences of such an approach

The neglect of racism as an ethical issue in health care

Race and racism has been increasingly implicated in known disparities in the health and health care of racial, ethnic and cultural minorities groups. Despite the obvious ethical implications of this observation, racism as an ethical issue per se has been relatively neglected in health care ethics discourse. In this paper consideration is given to addressing the following questions: What is it about racism and racial disparities in health and health care that these command our special moral scrutiny? Why has racism per se tended to be poorly addressed as an ethical issue in health care ethics discourse? And why, if at all, must racism be addressed as an ethical issue in addition to its positioning as a social, political, cultural and legal issue? It is suggested that unless racism is reframed and redressed as a pre-eminent ethical issue by health service providers, its otherwise preventable harmful consequences will remain difficult to identify, anticipate, prevent, manage, and remedy.
