Systematic examination of publicly-available information reveals the diverse and extensive corporate political activity of the food industry in Australia

BACKGROUND: The political influence of the food industry, referred to as corporate political activity (CPA), represents a potential barrier to the development and implementation of effective public health policies for non-communicable diseases prevention. This paper reports on the feasibility and limitations of using publicly-available information to identify and monitor the CPA of the food industry in Australia. METHODS: A systematic search was conducted for information from food industry, government and other publicly-available data sources in Australia. Data was collected in relation to five key food industry actors: the Australian Food and Grocery Council; Coca Cola; McDonald's; Nestle; and Woolworths, for the period January 2012 to February 2015. Data analysis was guided by an existing framework for classifying CPA strategies of the food industry. RESULTS: The selected food industry actors used multiple CPA strategies, with 'information and messaging' and 'constituency building' strategies most prominent. CONCLUSIONS: The systematic analysis of publicly-available information over a limited period was able to identify diverse and extensive CPA strategies of the food industry in Australia. This approach can contribute to accountability mechanisms for NCD prevention.

Navigating the ethics of cross-cultural health promotion research

Health promotion researchers must consider the ethics of their research, and are usually required to abide by a set of ethical requirements stipulated by governing bodies (such as the Australian National Health and Medical Research Council) and human research ethics committees (HRECs). These requirements address both deontological (rule-based) and consequence-based issues. However, at times there can be a disconnect between the requirements of deontological issues and the cultural sensitivity required when research is set in cultural contexts and settings etic to the HREC. This poses a challenge for health promotion researchers who must negotiate between meeting both the requirements of the HREC and the needs of the community with whom the research is being conducted. Drawing on two case studies, this paper discusses examples from cross-cultural health promotion research in Australian and international settings where disconnect arose and negotiation was required to appropriately meet the needs of all parties. The examples relate to issues of participant recruitment and informed consent, participants under the Australian legal age of consent, participant withdrawal when this seemingly occurs in an ad hoc rather than a formal manner and reciprocity. Although these approaches are context specific, they highlight issues for consideration to advance more culturally appropriate practice in research ethics and suggest ways a stronger anthropological lens can be applied to research ethics to overcome these challenges.

Social exclusion of Australian childless women in their reproductive years

Research suggests Australian childless women are at risk of pronatalism-driven social exclusion. This exploratory, mixed methods, cross-sectional study described and explored the social exclusion of Australian childless women aged 25 to 44 years, and asked: what are the nature and extent of social exclusion of childless women; and do the nature and extent of exclusion vary for different types of childless women? A total of 776 childless female Australian residents aged 25 to 44 years completed a self-administered questionnaire. Quantitative data were collected on childlessness types, indicators of exclusion and perceived stigmatisation and exclusion due to being childless. Data were analysed using descriptive statistics, One Way ANOVAs and Kruskal Wallis Analysis of Ranks. Qualitative data on childless women’s experiences were inductively thematically analysed. Findings suggest societal-level pronatalism drives exclusion of Australian childless women. While exclusion occurs in all domains of life, childless women experience more exclusion, and perceive more exclusion due to being childless, in the social and civic domains than the service and economic domains. Circumstantially and involuntarily childless women, followed by voluntarily childless women, perceive more exclusion due to being childless than undecided and future childed women. Experiences are influenced by the nature of women’s ‘deviance’ from pronatalism.

Women’s reproductive choices in Australia: mapping federal and state/territory policy instruments governing choice

The reproductive choices available to women, and the consequences of those choices, exist within the broader policy context whereby policy is influenced by pervasive ideologies of women’s roles in society and the family. Women’s reproductive rights and their resulting consequences are governed by policy at the federal and state/territory levels within Australia yet little is known about the number or scope of these policies. This study aimed to systematically search and map Australian policy to identify the number and scope of policies governing women’s reproductive choices and their consequences, including how policy interprets the role of women in society through their reproductive choices. The systematic search identified 147 Australian policies in 2013. The mapping of the policies identified common themes that drive policy agenda impacting women’s reproductive choices, including those where the focus is promoting motherhood and/or children, providing economic incentives, regulating reproduction, or a broader health focus. These policy agendas simultaneously construct and are shaped by the context in which women’s reproductive choices and impacts occur. Women’s reproductive choices are highly politicised and regulated, impacting women’s position within society.

Nutritional regulation of long-chain PUFA biosynthetic genes in rainbow trout (Oncorhynchus mykiss)

Most studies on dietary vegetable oil in rainbow trout (Oncorhynchus mykiss) have been conducted on a background of dietary EPA (20 : 5n-3) and DHA (22 : 6n-3) contained in the fishmeal used as a protein source in aquaculture feed. If dietary EPA and DHA repress their endogenous synthesis from α-linolenic acid (ALA, 18 : 3n-3), then the potential of ALA-containing vegetable oils to maintain tissue EPA and DHA has been underestimated. We examined the effect of individual dietary n-3 PUFA on the expression of the biosynthetic genes required for metabolism of ALA to DHA in rainbow trout. A total of 720 juvenile rainbow trout were allocated to twenty-four experimental tanks and assigned one of eight diets. The effect of dietary ALA, EPA or DHA, in isolation or in combination, on hepatic expression of fatty acyl desaturase (FADS)2a(Δ6), FADS2b(Δ5), elongation of very long-chain fatty acid (ELOVL)5 and ELOVL2 was examined after 3 weeks of dietary intervention. The effect of these diets on liver and muscle phospholipid PUFA composition was also examined. The expression levels of FADS2a(Δ6), ELOVL5 and ELOVL2 were highest when diets were high in ALA, with no added EPA or DHA. Under these conditions ALA was readily converted to tissue DHA. Dietary DHA had the largest and most consistent effect in down-regulating the gene expression of all four genes. The ELOVL5 expression was the least responsive of the four genes to dietary n-3 PUFA changes. These findings should be considered when optimising aquaculture feeds containing vegetable oils and/or fish oil or fishmeal to achieve maximum DHA synthesis.
