Serum vitamin D and falls in older women in residential care in Australia

Objectives: To determine the prevalence of vitamin D deficiency in older people in residential care and the influence that the level of vitamin D may have on their incidence of falls.

Design: Prospective cohort.

Setting: Residential care facilities for older people in several states of Australia.

Participants: Six hundred sixty-seven women in low-level care and 952 women in high-level care, mean age 83.7 years.

Measurements: Serum 25-hydroxyvitamin D (25D) levels and recognized risk factors for falls including current medication use, a history of previous fractures, weight, tibial length (as a surrogate for height), cognitive function, walking ability, and frequency of going outdoors were determined. The women in low-level care and high-level care were followed for an average of 145 and 168 days, respectively. Falls were recorded prospectively in diaries completed monthly by residential care staff.

Results: Vitamin D deficiency (defined as a serum 25D level below 25 nmol/L) was present in 144 (22%) women in low-level care and 428 (45%) in high-level care. After excluding 358 bed-bound residents and adjusting for weight, cognitive status, psychotropic drug use, previous Colles fracture, and the presence of wandering behavior, log serum 25D level remained independently associated with time to first fall. The adjusted hazards ratio was 0.74 (95% confidence interval=0.59–0.94; P=.01), implying a 20% reduction in the risk of falling with a doubling of the vitamin D level.

Conclusion: Vitamin D deficiency is common in residential care in Australia. A low level of serum vitamin D is an independent predictor of incident falls.

Measuring the impact of intimate partner violence on the health of women in Victoria, Australia

Objective: Using burden of disease methodology, estimate the health risks of intimate partner violence (IPV) among women in Victoria, Australia.

Methods: We calculated population attribute fractions (from survey data on the prevalence of IPV and the relative risks of associated health problems in Australia) and determined health outcomes by applying them to disability-adjusted life year estimates for the relevant disease and injury categories for Victoria, Australia for 2001.

Findings: For women of all ages IPV accounted for 2.9% (95% uncertainty interval 2.4-3.4%)  of the total disease and injury burden.  Among women 18-44 years of age, IPV was associated with 7.9% (95% uncertainty interval 6.4-935%) of the overall disease burden and was a larger risk to health than risk factors traditionally included in burden of disease studies, such as raised blood pressure, tobacco use and increased body weight.  Poor mental health contributed 73% and substance abuse 22% to the disease burden attributed to IPV.

Conclusion: Our findings suggest that IPV constitutes a significant risk to women's health.  Mental health policy-makers and health workers treating common mental health problems need to be aware that IPV is an important factor.  Future research should concentrate on evaluating effective interventions to prevent women being exposed to violence, and identifying the most appropriate mental health care for victims to reduce short- and long-term disability

Interest, nations, and the state in development: Instability in archipelic Southeast Asia

The Southeast Asian archipelago has become marked by divisions
within existing states, placing significant local constraints upon
the process of ‘development’. These divisions include ‘vertical’
challenges to the state, i.e. they have the capacity to split the state
into geographic divisions based on proto-nationalist identity, and
‘horizontal’ challenges to the state, defined by ethnic and
communal rivalry and conflict. This brief paper will canvas some
issues in such divisions.

Theorising men's violence towards women in refugee families : towards in intersectional feminist framework

Violence against women perpetrated by male partners, or ex-partners. is one of the most concerning and prevalent public health issues in the world today and is a major cause of injury and mental illness among women and children. Violence against women occurs in most societies irrespective of culture, socio-economic status or religion. Nevertheless, it has been identified that immigrant and refugee women are particularly at risk in cases of domestic violence (Easteal 1996: Narayan 1997; Human Rights Watch 2000; Walter 2001: Perilla 2003: Kang Kahler & Tesar 2003:). To make sense of this issue. we articulate an intersectional feminist framework that we used to analyse the results of an empirical investigation of men's violence against women in refugee families in Melbourne. II)

Although this research has investigated the complex field of domestic violence, culture. trauma and historical and contemporary disadvantage, it has a fundamental prerequisite standing that regardless of past and current experiences; men must take responsibility for their violence against women. Our concern is to understand how male domination manifests itself within each culture and emerging, changing cultures in the diaspora, to explore the connections with men's violence against women within the unique domain of the refugee experience.

Intake of B vitamins in childhood and adult life in relation to psychological distress among women in a British birth cohort

Background : Lower levels of B vitamins (particularly folate, vitamin B12 and vitamin B6) may be associated with psychological distress. Little is known about the impact of childhood nutrition on psychological distress in adult life.

Objective : We investigated whether prospectively measured childhood and adult dietary intakes of thiamin, riboflavin, niacin, folate, vitamin B6 and vitamin B12 were related to the psychological distress of women in mid-age, taking into account socio-economic, behavioural and lifestyle factors.

Design : Prospective data were collected from a cohort of 636 British women followed up since their birth in 1946. Participants completed a 28-item, scaled version of the General Health Questionnaire (GHQ-28) to measure psychological distress at age 53 years. Dietary intakes in childhood (at age four) were determined by 24h recall and in adulthood (at age 36, 43 and 53 years) by a 5d food record.

Results : Low dietary vitamin B12 intake at age 53 was associated with higher psychological distress at that age. Women in the lowest third of vitamin B12 intake in adulthood had a higher GHQ-28 score compared with those in the highest third (percentage change, adjusted regression coefficient, 21 (95% CI 3, 39)). There were no other significant associations between dietary B vitamin intake in childhood or adulthood and psychological distress in the cohort.

Conclusions : Overall, there is evidence that intake of vitamin B12 at age 53 is related to adult psychological distress but there is no evidence for the effects of other adult B vitamin intakes or childhood intakes on psychological distress.

Women in international assignments in multinational enterprises

Research in the US, Europe and Australia shows that women's participation in international assignments is low. This book seeks to understand why this is the case. A conceptual framework of the factors related to the participation of women in international assignments was developed. Areas covered include the organisational environment, interpersonal factors and support, individual variables, characteristics and repatriation factors. Three studies were conducted using international assignees, repatriates and human resource managers. The conceptual framework was empirically supported by the three studies. It is anticipated that this knowledge will assist women, HR managers and the HR function to develop selection systems, environments and attitudes that are supportive of women participating in international assignments in MNEs. The research should be useful to practitioners, and academics who are interested in the field of international human resource management, and to women considering participating in an international assignment.

The role of leadership theory in raising the profile of women in management

Purpose: To consider how leadership theories have helped or hindered raising the profile of women in management and leadership roles.

Design/methodology/approach: This paper traces the earlier leadership theories through to the contemporary research on transactional and transformational leadership styles and offers a viewpoint on how each theory has contributed, or otherwise, to an awareness and acceptance of women in management and leadership roles.

Findings:  In 1990, research began to report gender differences in leadership styles with female managers being seen in positive terms as participative, democratic leaders. More recent work reports that women are believed to exhibit more transformational leadership style than their male colleagues, and this is equated with effective leadership.

Research limitations/implications:  All of the earlier theories on leadership excluded women and this exacerbated the problem of women not being seen as an appropriate fit in a management or leadership role. Recent findings clearly describe that the transformational qualities of leadership that women exhibit are required by the flatter organisational structures of today. Therefore, a more positive outcome for women advancing to senior roles of management or leadership may be observed in the future.

Originality/value:  The paper reviews the major leadership theories, and links these to a timeframe to illustrate how women were not visible in a management context until relatively recently. Such an omission may have contributed to the continuing low numbers of women who advance to senior management and leadership roles.
