Scoping study to inform the development of the new national nutrition policy for Australia

This comprehensive report (748 pages) scopes a new nutrition policy for Australia (RFT 028/1213) Australian Department of Health and Ageing. Optimum nutrition is fundamental to good health. It is essential for the normal growth and physical and cognitive development of infants and children, contributes significantly to quality of life, wellbeing and workforce productivity, enhances resistance to infection and reduces the risk of obesity, chronic disease and premature death (AIHW 2012; NHMRC 2013). This scoping study reviews the current literature to identify: - key population health issues related to diet and nutrition within the Australian population; and - where gaps in current policy are evident. The scoping study reviews the literature on past and present national and international nutrition policies, strategies (policy actions), interventions and evaluations. The study analyses the evidence from the literature review and formulates recommendations regarding the key elements of effective nutrition policies including scope, guiding principles, format, key inclusions (content), development processes, governance, implementation, timelines, monitoring and surveillance, evaluation and review to guide the development of a new comprehensive National Nutrition Policy for Australia.

We can close the Indigenous nutrition gap – here’s how

After years of neglect and a notable absence in last week’s Closing the Gap report, nutrition is finally being recognised as integral to closing the gap on Indigenous disadvantage. This belated realisation is puzzling, given poor diet is a major cause of type 2 diabetes, heart disease, kidney disease and some cancers. Nutrition is particularly poor in Aboriginal and Torres Strait Islander communities, where it is estimated that at least 19% of the burden of disease is due to poor diet; much more than due to smoking...

Psychological distress may affect nutrition indicators in Australian adults

- Objective The purpose of this research was to explore which demographic and health status variables moderated the relationship between psychological distress and three nutrition indicators: the consumption of fruits, vegetables and takeaway. - Method We analysed data from the 2009 Self-Reported Health Status Survey Report collected in the state of Queensland, Australia. Adults (N = 6881) reported several demographic and health status variables. Moderated logistic regression models were estimated separately for the three nutrition indicators, testing as moderators demographic (age, gender, educational attainment, household income, remoteness, and area-level socioeconomic status) and health status indicators (body mass index, high cholesterol, high blood pressure, and diabetes status). - Results Several significant interactions emerged between psychological distress, demographic (age, area-level socioeconomic status, and income level), and health status variables (body mass index, diabetes status) in predicting the nutrition indicators. Relationships between distress and the nutrition indicators were not significantly different by gender, remoteness, educational attainment, high cholesterol status, and high blood pressure status. - Conclusions The associations between psychological distress and several nutrition indicators differ amongst population subgroups. These findings suggest that in distressed adults, age, area-level socio-economic status, income level, body mass index, and diabetes status may serve as protective or risk factors through increasing or decreasing the likelihood of meeting nutritional guidelines. Public health interventions for improving dietary behaviours and nutrition may be more effective if they take into account the moderators identified in this study rather than using global interventions.

Nutrition during noninvasive ventilation: clinical determinants and key practical recommendations

Malnutrition and poor nutritional intake have been identified as key issues associated with poorer clinical outcomes in chronic obstructive pulmonary disease (COPD) patients. There is strong evidence showing nutritional support is effective in treating malnutrition in stable COPD, but there is only limited research regarding nutritional status in patients treated with noninvasive ventilation (NIV). The impact of NIV during acute exacerbations of respiratory disease on nutritional status requires further investigation.

Playing the policy game: A review of the barriers and enablers of nutrition policy change

- Objective To progress nutrition policy change and develop more effective advocates, it is useful to consider real-world factors and practical experiences of past advocacy efforts to determine the key barriers and enablers to nutrition policy change. This review aimed to identify and synthesize the enablers and barriers to public policy change within the field of nutrition. - Design Electronic databases were searched systematically for studies examining policymaking in public health nutrition. An interpretive synthesis was undertaken. Setting: International, national, state and local government jurisdictions within high-income, democratic countries. - Results Sixty-three studies were selected for inclusion. Numerous themes were identified explaining the barriers and enablers to policy change, all of which fell under the overarching category, ‘political will’, underpinned by a second major category, ‘public will’. Sub-themes, including pressure from industry; neoliberal ideology; use of emotions and values, and being visible were prevalent in describing links between public will, political will and policy change. - Conclusions The frustration around lack of public policy change in nutrition frequently stems from a belief that policymaking is a rational process in which evidence is used to assess the relative costs and benefits of options. The findings from this review confirm that evidence is only one component of influencing policy change. For policy change to occur there needs to be the political will, and often the public will, for the proposed policy problem and solution. This review presents a suite of enablers which can assist health professionals to influence political and public will in future advocacy efforts.

Relating food literacy to nutrition and health

This chapter describes the evolution of a model to propose the relationship between food literacy and nutrition. This model can also be used as a framework for program planning, implementation and evaluation. Practitioners and policy makers invest in food literacy with outcome expectations beyond diet quality. For this reason, a second model was developed to conceptualise the role of food literacy with respect to food security, body weight and chronic disease risk. This second model is useful in positioning food literacy within multi-strategic public health nutrition and chronic disease plans.
