New Zealanders' attitudes to milk : implications for public health

Objective: To identify consumer attitudes and beliefs about (liquid) milk that may be barriers to consumption.

Design: Two random-quota telephone surveys conducted in Auckland one year apart. Respondents were questioned about their usual milk intake and their attitudes to milk. The questionnaire included attitude items that reflected the main themes of consumer interest in milk.

Setting: New Zealand.

Subjects: Seven hundred and thirteen respondents in the baseline survey and a separate sample of 719 respondents in the follow-up survey.

Results: At least one-third of the respondents consumed less than a glass (250ml) of milk a day. Non-consumption was highest in young women (15%). People's concerns about milk related to what was important in their lives; what threatens them physically and emotionally. Women held more positive attitudes but they were concerned about the fat content of milk. Men were less aware of milk's nutritional benefits and as a result were less appreciative of its value.

Conclusions: There is an opportunity to develop public health initiatives to address the barriers to drinking milk. Industry–health alliances may be an effective means to provide positive nutrition messages about milk and to engage the support of health professionals.

Investigating housing supply and monetary policy under global economic turbulence

This research has contributed to literature by identifying the impacts of monetary policy and global economic turbulence on the supply side of the housing sector under a vector error correction model. The research outcomes provided policy makers with an insight to change Australia's housing shortage and declining housing affordability.

Genetics and public health - evolution, or revolution?

During the 19th and early 20th century, public health and genetics shared common ground through similar approaches to health promotion in the population. By the mid-20th century there was a division between public health and genetics, with eugenicists estranged and clinical genetics focused on single gene disorders, usually only relevant to small numbers of people. Now through a common interest in the aetiology of complex diseases such as heart disease and cancer, there is a need for people working in public health and genetics to collaborate. This is not a comfortable convergence for many, particularly those in public health. Nine main concerns are reviewed: fear of eugenics; genetic reductionism; predictive power of genes; non-modifiable risk factors; rights of individuals compared with populations; resource allocation; commercial imperative; discrimination; and understanding and education. This paper aims to contribute to the thinking and discussion about an evolutionary, multidisciplinary approach to understanding, preventing, and treating complex diseases.

This is public health : Australian students’ understanding of public health

This is Public Health Campaign,Young adults are a frequent target of health promotion campaigns in Australia yet there is evidence to suggest that this cohort has little understanding of the nature and intent of Public Health initiatives in their own environment. This paper describes the results of a study that evaluated the knowledge and understanding of public health of a sample of 333 first year health science students at an Australian University. Students were asked to submit photographs depicting their ideas about public health and accompany these with a written rationale for their choices. The results of the study suggest that the students at this level have a narrow interpretation of public health and do not understand the organized nature of public health efforts or the aims of such initiatives. This study provides important insight into the thinking of this cohort of young Australians, both in the context of preparing them for future careers in public health as well as in relation to their response to health promotion campaigns targeting them.

Preventing mental health problems in children : the families in mind population-based cluster randomised controlled trial.

Background

Externalising and internalising problems affect one in seven school-aged children and are the single strongest predictor of mental health problems into early adolescence. As the burden of mental health problems persists globally, childhood prevention of mental health problems is paramount. Prevention can be offered to all children (universal) or to children at risk of developing mental health problems (targeted). The relative effectiveness and costs of a targeted only versus combined universal and targeted approach are unknown. This study aims to the effectiveness, costs and uptake of two approaches to early childhood prevention of mental health problems ie: a Combined universal-targeted approach, versus a Targeted only approach, in comparison to current primary care services (Usual care).
Design

Three armed, population-level cluster randomised trial (2010-2014) within the universal, well child Maternal Child Health system, attended by more than 80% of families in Victoria, Australia at infant age eight months. Participants: Families of eight month old children from nine participating local government areas. Randomised to one of three groups: Combined, Targeted or Usual care. Intervention: (a) the Combined universal and targeted program where all families are offered the universal Toddlers Without Tears group parenting program followed by the targeted Family Check-Up one-on-one program or (b) the Targeted Family Check-Up program. The Family Check-Up program is only offered to children at risk of behavioural problems. Analysis: Participants will be analysed according to the trial arm to which they were randomised, using logistic and linear regression models to compare primary and secondary outcomes. An economic evaluation (cost consequences analysis) will compare incremental costs to all incremental outcomes from a societal perspective.
Discussion

This trial will inform public health policy by making recommendations about the effectiveness and cost-effectiveness of these early prevention programs. If effective prevention programs can be implemented at the population level, the growing burden of mental health problems could be curbed.

Evidence-informed health policy - the crucial role of advocacy

Health policy makers and clinicians often face similar decision-making challenges. The issues are turbulent, characterised by high risk and complexity, often involve value conflicts and occur in settings of rapid change. Policy makers' decisions are under increasing scrutiny for their use of evidence, with many health policies reflecting political influence rather than rigorous analysis. The evidence-based policy movement offers a range of accounts for this. We argue that advocacy in three critical areas helps explain when evidence is used in the policy making process and then contrast the impacts of advocacy for evidence use in two nutrition policy cases.
