Mediators of physical activity behavior change among women with young children

Background Women with children are less likely to engage in adequate physical activity (PA) than women without children. This study aimed to evaluate the efficacy of two strategies for promoting increased PA among mothers of preschool-aged children, and to explore the mediators of any resulting change in PA behavior. Design Controlled intervention trial incorporating repeated data collection from 554 women, randomized to one of three experimental conditions. Intervention Group 1 served as a control, while women in Groups 2 and 3 were given print information about overcoming PA barriers. Women in Group 3 were also invited to discuss the development of local strategies for the promotion of PA among mothers of young children. The primary strategies included increasing partner support, social advocacy, and capacity building, and were implemented through collaboration among participants, researchers, and community organizations. Main Outcome Measures Adequate physical activity (PA), self-efficacy (SE) and partner support (PS). Results: Following the intervention, women in Group 3 were significantly more likely to meet guidelines for PA than controls (odds ratio [OR]=1.71, confidence interval [CI]=1.05–2.77)] after controlling for age and PA at baseline. After controlling for baseline PA, residualized change in SE (OR=1.86, CI=1.17–2.94) and PS (OR=2.29, CI=1.46–3.58) significantly predicted meeting guidelines. After controlling for residual change in PS and SE, the significant intervention effect was attenuated (Group 3 OR=1.40, CI=0.76–2.36), indicating that partner support and self-efficacy may be mediators of physical activity behavior change. Conclusions The findings indicate that community participation approaches that facilitate increased self-efficacy and partner support can be effective in increasing PA among mothers of young children.

Is unsupervised exercise following breast cancer safe for all women?

One in eight women living in developed countries will be diagnosed with breast cancer before the age of 85, with the mean age at first diagnosis approximately 60 years. Stage I represents just under 50% of diagnoses, while 45% of cases are diagnosed at later stages (stages II to IV; the remainder being unknown stage). Breast cancer continues to be the most common cause of cancer-related deaths in women , and although survival for women with stage I disease is high (98% 5-year relative survival), survival is significantly lower for those diagnosed with more advanced disease stage (i.e., stages II to IV, 83%; an unknown stage, 50%) .

Gender dimensions of resource extraction : the place of women

This chapter examines two core dimensions of women’s gendered experiences of mining in Australia and more specifically in Western Australia (WA). First, the chapter explores what has been and continues to be women’s principal relationship to mining encapsulated in the social and cultural identity of the ‘mining wife’ and, more recently, ‘fly-in/fly-out (FIFO) wife’. Second, the chapter addresses the fraught emergence of women as mineworkers. As the research presented in this chapter makes clear, the human cost of developmentalism was and continues to be deeply gendered.

Exploring the factor structure of a new self- and other-oriented alcohol expectancy scale relating to sexual coercion and vulnerability

Introduction and Aim: Sexual assaults commonly involve alcohol use by the perpetrator, victim, or both. Beliefs about alcohol’s effects may impact on people’s perceptions of and responses to men and women who have had such experiences while intoxicated from alcohol. This study aimed to develop an alcohol expectancy scale that captures young adults’ beliefs about alcohol’s role in sexual aggression and victimisation. Design and Methods: Based on pilot focus groups, an initial pool of 135 alcohol expectancy items was developed, checked for readability and face validity, and administered via a cross-sectional survey to 201 male and female university students (18-25 years). Items were specified in terms of three target drinkers: self, men, and women. In addition, a social desirability measure was included. Results: Principal Axis Factoring revealed a 4-factor solution for the targets men and women and a 5-factor solution for the target self with 72 items retained. Factors related to sexual coercion, sexual vulnerability, confidence, self-centredness, and negative cognitive and behavioural effects. Social desirability issues were evident for the target self, but not for the targets men and women. Discussion and Conclusions: Young adults link alcohol’s effects with sexual vulnerabilities via perceived risky cognitions and behaviours. Due to social desirability, these expectancies may be difficult to explicate for the self but may be accessible instead via other-oriented assessment. The Sexual Coercion and Vulnerability Alcohol Expectancy Scale has potential as a tool to elucidate the established tendency for observers to excuse intoxicated sexual perpetrators while blaming intoxicated victims.

Engendering the responsibility to protect : women and the prevention of mass atrocities

This article explores the relationship between the Responsibility to Protect (R2P) and the pursuit of the so-called ‘Women, Peace and Security’ (WPS) agenda at the UN. We ask whether the two agendas should continue to be pursued separately or whether each can make a useful contribution to the other. We argue that while the history of R2P has not included language that deliberately evokes the protection of women and the promotion of gender in preventing genocide and mass atrocities, this does not preclude the R2P and WPS agendas becoming mutually reinforcing. The article identifies cross-cutting areas where the two agendas may be leveraged for the UN and member states to address the concerns of women as both actors in need of protection and active agents in preventing and responding to genocide and mass atrocities, namely in the areas of early warning.

An examination of microfinance self-help groups and the poorest of the poor women in Tamil Nadu, India

This study examined the formation and operation of women's microfinance self-help groups in southern India and investigated whether or not the poorest of the poor women were accepted as members of those groups. The study found that caste was used as a selection criterion. Many eligible women excluded themselves from joining the self-help group due to their own lack of education, age, poor health, poverty and lack of trust in the system. The research revealed that self-help groups enhanced women's income and education, improved village infrastructure, and reduced household conflict. Factors that might prevent inclusion of the poorest of the poor in future microfinance programs were identified.

The alcohol culture of mature-aged women : similarities and differences across borders

Introduction: Relatively few attempts have been made to describe and understand women’s alcohol consumption beyond adolescence and young adulthood. In particular, there has been a lack of studies focusing on the alcohol culture that surrounds and guides mature-aged women’s drinking. As part of a larger cross-national comparison, the present study sought to address this gap by identifying the shared beliefs and values that impact on drinking outcomes among mature-aged women in Sweden and Australia. Method: The study was guided by an ethnographic methodology. To generate data, a series of semi-structured interview were conducted with 17 Australian (age = 45-57 years; M = 52.1, SD = 3.9) and 19 Swedish (age = 45-58 years; M = 52.2, SD = 4.8) women. All interviews were transcribed verbatim and thematically analysed. Results: With age, the focus of alcohol as a single purpose vehicle for intoxication had given way to a focus on the enjoyment and ritual of drinking itself; taste had become increasingly important and alcohol was strongly associated with pleasurable environments and experiences. The view of alcohol as a taste experience was particularly pronounced among the Swedish women, with alcohol (most commonly wine) often seen as inseparable from food. Among the Swedish women, this view of alcohol was also associated with a strong de-emphasis of the pharmacological effects of alcohol. In contrast, several Australian women understood and used alcohol as relief for anxiety and stress. Moderate drinking was linked to the social construction of both age and gender in the two samples, while heavy or abusive alcohol consumption was associated with strong proscriptive norms and stigma. Conclusions: Australian and Swedish women share a number of beliefs and values around alcohol, however, these findings also show unique country-level differences. Implications for drinking outcomes are discussed.

Molecular profiling of human mammary gland links breast cancer risk to a p27(+) cell population with progenitor characteristics

Early full-term pregnancy is one of the most effective natural protections against breast cancer. To investigate this effect, we have characterized the global gene expression and epigenetic profiles of multiple cell types from normal breast tissue of nulliparous and parous women and carriers of BRCA1 or BRCA2 mutations. We found significant differences in CD44+ progenitor cells, where the levels of many stem cell-related genes and pathways, including the cell-cycle regulator p27, are lower in parous women without BRCA1/BRCA2 mutations. We also noted a significant reduction in the frequency of CD44+p27+ cells in parous women and showed, using explant cultures, that parity-related signaling pathways play a role in regulating the number of p27+ cells and their proliferation. Our results suggest that pathways controlling p27+ mammary epithelial cells and the numbers of these cells relate to breast cancer risk and can be explored for cancer risk assessment and prevention.

The association between social support and levels of psychological distress in pregnant women in Australia

The purpose of this study was to explore associations between forms of social support and levels of psychological distress during pregnancy. Methods: A cross-sectional analysis of 2,743 pregnant women from south-east Queensland, Australia, was conducted utilising data collected between 2007-2011 as part of the Environments for Healthy Living (EFHL) project, Griffith University. Psychological distress was measured using the Kessler 6; social support was measured using the following four factors: living with a partner, living with parents or in-laws, self-perceived social network, and area satisfaction. Data were analysed using an ordered logistic regression model controlling for a range of socio-demographic factors. Results: There was an inverse association between self-perceived strength of social networks and levels of psychological distress (OR = 0.77; 95%CI: 0.70, 0.85) and between area satisfaction and levels of psychological distress (OR = 0.77; 95%CI: 0.69, 0.87). There was a direct association between living with parents or in-laws and levels of psychological distress (OR = 1.50; 95%CI: 1.16, 1.96). There was no statistically significant association between living with a partner and the level of psychological distress of the pregnant woman after accounting for household income. Conclusion: Living with parents or in-laws is a strong marker for psychological distress. Strategies aiming to build social support networks for women during pregnancy have the potential to provide a significant benefit. Policies promoting stable family relationships and networks through community development could also be effective in promoting the welfare of pregnant women.

She'll be right mate : inclusivity experiences of men and women working in projects

Occupational segregation is a major source of labour market rigidity and economic inefficiency due to a waste of human resources. Organisations are repeatedly recognised as gendered constructs exhibiting sustained work segregation, income and status inequality, as well as cultural and individual images of gender, and these are perpetuated through their processes, practices and pressures (Acker, 1990). A large percentage of Australia’s workforce is now employed in project-based or project-oriented organisations, leading to the claim that Australia is a project-based economy. For a continued strong performance in this economy, organisations that employ project personnel will need to consider how they address inclusivity and equality in diversity in project based temporary organisations to ensure the supply of high quality project professionals into the future. This paper investigates the inclusion processes experienced and exercised by men and women working in temporary organisations in project situations through a review of reports on the inclusion processes experienced by 60 project managers and project workers in three project based industries in Australia. Results indicate that temporary organisations are not implementing equality and diversity management strategies at the macro level and project workers are accepting this lack of recognition. However inclusivity and equality at the micro level of the team is seen as vital.

Longitudinal change in sleep and daytime sleepiness in postpartum women

Sleep disruption strongly influences daytime functioning; resultant sleepiness is recognised as a contributing risk-factor for individuals performing critical and dangerous tasks. While the relationship between sleep and sleepiness has been heavily investigated in the vulnerable sub-populations of shift workers and patients with sleep disorders, postpartum women have been comparatively overlooked. Thirty-three healthy, postpartum women recorded every episode of sleep and wake each day during postpartum weeks 6, 12 and 18. Although repeated measures analysis revealed there was no significant difference in the amount of nocturnal sleep and frequency of night-time wakings, there was a significant reduction in sleep disruption, due to fewer minutes of wake after sleep onset. Subjective sleepiness was measured each day using the Karolinska Sleepiness Scale; at the two earlier time points this was significantly correlated with sleep quality but not to sleep quantity. Epworth Sleepiness Scores significantly reduced over time; however, during week 18 over 50% of participants were still experiencing excessive daytime sleepiness (Epworth Sleepiness Score ≥12). Results have implications for health care providers and policy makers. Health care providers designing interventions to address sleepiness in new mothers should take into account the dynamic changes to sleep and sleepiness during this initial postpartum period. Policy makers developing regulations for parental leave entitlements should take into consideration the high prevalence of excessive daytime sleepiness experienced by new mothers, ensuring enough opportunity for daytime sleepiness to diminish to a manageable level prior to reengagement in the workforce.

Women, peace and security as an ASEAN priority

The Association of South East Asian Nations (ASEAN) Secretariat and its member states have repeatedly professed their commitment to the protection and advancement of women’s economic and human rights. Such commitments have included the Declaration on the Advancement of Women in ASEAN in 1988, the ASEAN Declaration on the Elimination of Violence Against Women in 2004, and the ASEAN Declaration of Human Rights in 2012, as well as the establishment of the ASEAN Committee on Women in 2002 and the ASEAN Commission on the Promotion and Protection of Women and Children in 2009. However, none of these regional commitments or institutions expressly take up the core concern of the Women, Peace and Security (WPS) agenda set out in United Nations Security Council (UNSC) Resolution 1325 in 2000. ASEAN has no 1325 regional action plan and amongst the ASEAN membership, the Philippines is the only state that has adopted a 1325 National Action Plan (NAP). We explore the possible reasons for lack of ASEAN institutional engagement with 1325, outline the case for regional engagement, and suggest specific roles for ASEAN Secretariat, donor governments and individual member states to commit to UNSCR 1325 as a regional priority.

Differential subcellular and extracellular localisations of proteins required for insulin-like growth factor- and extracellular matrix-induced signalling events in breast cancer progression

Background: Cancer metastasis is the main contributor to breast cancer fatalities as women with the metastatic disease have poorer survival outcomes than women with localised breast cancers. There is an urgent need to develop appropriate prognostic methods to stratify patients based on the propensities of their cancers to metastasise. The insulin-like growth factor (IGF)-I:IGF binding protein (IGFBP):vitronectin complexes have been shown to stimulate changes in gene expression favouring increased breast cancer cell survival and a migratory phenotype. We therefore investigated the prognostic potential of these IGF- and extracellular matrix (ECM) interaction-induced proteins in the early identification of breast cancers with a propensity to metastasise using patient-derived tissue microarrays. Methods: Semiquantitative immunohistochemistry analyses were performed to compare the extracellular and subcellular distribution of IGF- and ECM-induced signalling proteins among matched normal, primary cancer and metastatic cancer formalin-fixed paraffin-embedded breast tissue samples. Results: The IGF- and ECM-induced signalling proteins were differentially expressed between subcellular and extracellular localisations. Vitronectin and IGFBP-5 immunoreactivity was lower while β1 integrin immunoreactivity was higher in the stroma surrounding metastatic cancer tissues, as compared to normal breast and primary cancer stromal tissues. Similarly, immunoreactive stratifin was found to be increased in the stroma of primary as well as metastatic breast tissues. Immunoreactive fibronectin and β1 integrin was found to be highly expressed at the leading edge of tumours. Based on the immunoreactivity it was apparent that the cell signalling proteins AKT1 and ERK1/2 shuffled from the nucleus to the cytoplasm with tumour progression. Conclusion: This is the first in-depth, compartmentalised analysis of the distribution of IGF- and ECM-induced signalling proteins in metastatic breast cancers. This study has provided insights into the changing pattern of cellular localisation and expression of IGF- and ECM-induced signalling proteins in different stages of breast cancer. The differential distribution of these biomarkers could provide important prognostic and predictive indicators that may assist the clinical management of breast disease, namely in the early identification of cancers with a propensity to metastasise, and/or recur following adjuvant therapy.
