NHMRC information paper: evidence on the effectiveness of homeopathy for treating health conditions
This paper provides a summary of evidence from research on the effectiveness of homeopathy in treating health conditions in humans.
Findings
There was no reliable evidence from research in humans that homeopathy was effective for treating the range of health conditions considered: no good-quality, well-designed studies with enough participants for a meaningful result reported either that homeopathy caused greater health improvements than placebo, or caused health improvements equal to those of another treatment.
For some health conditions, studies reported that homeopathy was not more effective than placebo. For other health conditions, there were poor-quality studies that reported homeopathy was more effective than placebo, or as effective as another treatment. However, based on their limitations, those studies were not reliable for making conclusions about whether homeopathy was effective. For the remaining health conditions it was not possible to make any conclusion about whether homeopathy was effective or not, because there was not enough evidence.
Conclusions
Based on the assessment of the evidence of effectiveness of homeopathy, NHMRC concludes that there are no health conditions for which there is reliable evidence that homeopathy is effective.
Homeopathy should not be used to treat health conditions that are chronic, serious, or could become serious. People who choose homeopathy may put their health at risk if they reject or delay treatments for which there is good evidence for safety and effectiveness. People who are considering whether to use homeopathy should first get advice from a registered health practitioner. Those who use homeopathy should tell their health practitioner and should keep taking any prescribed treatments
Health communication implications of the perceived meanings of terms used to denote unhealthy foods
Background: Using appropriate terminology in nutrition education programs and behaviour change campaigns is important to optimise the effectiveness of these efforts. To inform future communications on the topic of healthy eating, this study explored adultsâ perceptions of the meaning of four terms used to describe unhealthy foods: junk food, snack food, party food, and discretionary food. Methods: Australian adults were recruited to participate in an online survey that included demographic items and open-ended questions relating to perceptions of the four terms. In total, 409 respondents aged 25â64 years completed the survey. Results: âJunk foodâ was the term most clearly aligned with unhealthiness, and is therefore likely to represent wording that will have salience and relevance to many target audience members. Snack foods were considered to include both healthy and unhealthy food products, and both snack foods and party foods were often described as being consumed in small portions. Despite being used in dietary guidelines, the term âdiscretionary foodâ was unfamiliar to many respondents. Conclusions: These results demonstrate that different terms for unhealthy foods can have substantially different meanings for audience members. A detailed understanding of these meanings is needed to ensure that nutrition guidance and health promotion campaigns use appropriate terminology
Information paper: evidence on wind farms and human health
This Information Paper provides Australians with a summary of the evidence on possible health effects of wind farms in humans and explains how NHMRC developed its summary based on the findings of independent reviews of the evidence. It is intended for use by any person or group interested in wind farms.
Wind farms in Australia
Wind turbines use rotating blades attached to towers to convert wind energy into electricity. A group of wind turbines is known as a wind farm and may be located on land or offshore. Wind turbine design has evolved over the last 20 years to enable better harnessing of wind energy.
Wind farms have been promoted as a viable and sustainable alternative to traditional, non-renewable forms of energy production. Since the introduction of the Renewable Energy Act 2000, the number of wind farms in Australia has grown substantially. At the end of 2013, there were 68 wind farms across the country and more were being constructed or planned.
Why NHMRC is conducting this work
NHMRC is responsible for ensuring that Australians receive the best available, evidence-based advice on matters relating to improving health and to preventing, diagnosing and treating disease. Concern about the effects on health from living near a wind farm has been expressed by some members of the community. Therefore, NHMRC examined the evidence on health effects associated with exposure to specific emissions from wind farms â noise, shadow flicker and electromagnetic radiation.
The current investigation of the potential health effects of wind farms builds upon NHMRCâs previous work in this area. In 2010, NHMRCâs Public statement: Wind turbines and health was published, with supporting evidence from Wind turbines and health: A rapid review of the evidence. The 2010 NHMRC Public Statement concluded that there âis currently no published scientific evidence to positively link wind turbines with adverse health effectsâ. Due to the limited amount of published scientific literature, NHMRC committed to carrying out a more extensive search for evidence.
This Information Paper provides an update to NHMRCâs previous work in this area. It is based on a comprehensive review of the available scientific evidence following well-established systematic review principles, which provide the most rigorous process for identifying and critically appraising evidence.
In Australia, responsibility for regulating the planning, development and operation of wind farms lies with state, territory and local governments. The outcomes of NHMRCâs review may assist these organisations to make decisions about the regulation of wind farms.
NHMRCâs review of the evidence will enable well-designed and targeted research to be undertaken in areas that have been identified as gaps in the evidence base
Beyond Chapter 4.7
Chapter 4.7 of the National Statement on Ethical Conduct in Human Research refers specifically to Aboriginal and Torres Strait Islander Peoples. It lays out the points at which researchers working with Aboriginal and Torres Strait Islanders must consider their approach, and the engagement with individuals, communities or groups who are involved in or affected by their research. History, of Australia and of research involving Aboriginal and Torres Strait Islander Australians, has informed this approach. The response to that history has been a rational, institutionalised, systematic demand for a different perception of what should direct research and research processes to ensure engagement with and service to the community with whom the researchers wish to do the work. This paper considers whether these principles could inform the approach to other research work.not applicabl
In their own words: A qualitative study exploring influences on the food choices of university students
Issue addressed: University students generally make independent decisions regarding food choices. Current research about knowledge of Australian Dietary Guidelines (ADG), sources of nutrition information and influences on food choices for this group is scarce.
Methods: Qualitative data were collected from genderâseparated focus groups comprising four female (n = 31) and four male (n = 18) to identify: knowledge of ADG; sources of nutrition information; factors that influence food choices; perceived relevant nutrition messages and how best to deliver them.
Results: Gaps in knowledge were identified particularly regarding number of serves and serving size for food groups. Social media was the most commonly reported source of knowledge. Social media was also a major influence on food choice due to its impact on body ideals.
Conclusion: Current health promotion nutrition messages were perceived irrelevant given the focus on longâterm health risks. Health and adhering to the ADG were not identified as important. The desire to look a particular way was the major influence on food choices.
So what? While there is an awareness of ADG, our participants made a deliberate decision not to follow them. This provides a challenge for developing relevant preventive health messages for this target audience

Implementing a strategic plan for child health: a Sydney case study
Aim: The aim of this paper is to describe the implementation of a strategic plan, âHealth Gain for Children and Youth of Central Sydneyâ, over a 10 year period to December 2005.
Methods: Descriptive information was obtained from the records and minutes of all relevant committees, interviews with key workers who were involved with the committees, managers and senior health professionals, and from the involvement of the authors throughout the process of the implementation.
Results: An implementation steering committee was established to oversee the implementation of the plan. Rather than adopting a uniform approach to assigning responsibility for the implementation of each strategy in the plan or developing specific costs and time frames for each strategy, a more pragmatic, flexible and opportunistic approach was taken. Most of the planâs strategies were implemented over a 7 year time frame using a combination of service reorientation and implementation of new programs, some of which were funded from sources not anticipated during the development of the plan. Implementation required a dedicated driver, commitment at senior level and participation by many staff at many levels. Outcomes, monitored through data collected at 5 year intervals, revealed positive trends in a number of child and youth health indicators.
Conclusions: The successful implementation of the strategic plan required pragmatism, flexibility, opportunism and the commitment and involvement of staff at all organisational levels. . It is envisaged that this approach provides a firm base for future evidence based developments to benefit the health and well being of children, youth and their families and reduce health inequities
Paying clinicians to join clinical trials : a review of guidelines and interview study of trialists
Background: The motivations of clinicians to participate in clinical trials have been little studied. This project explored the potential role of payment for participation in publicly funded clinical trials in the UK. The aims were to review relevant guidelines and to collate and analyse views of clinical trialists on the role of payments and other factors that motivated clinicians to join clinical trials.
Methods: Review of guidelines governing payments to clinicians for recruitment to trials. Semistructured
interviews with a range of NHS clinical trial leaders, analysed using qualititative methods.
Results: While UK guidelines had little to say specifically on payments linked to recruitment, all payments have become highly regulated and increasingly transparent. Interview participants believed that expenses arising from research should be covered. Payments in excess of expenses
were seen as likely to increase participation but with the risk of reducing quality. Motivations such
as interest in the topic, the scope for patients to benefit and intellectual curiosity were considered more important. Barriers to involvement included bureaucracy and lack of time.
Discussion: Limited scope exists for paying clinicians over-and-above the cost of their time to be involved in research. Most trialists favour full payment of all expenses related to research.
Conclusion: Payment of clinicians beyond expenses is perceived to be a less important motivating factor than researching important, salient questions, and facilitating research by reducing bureaucracy and delay
