Issue addressed: The increase in mental health disorders worldwide makes it important to recognise health promotion interventions that are effective, accessible and affordable. Although natural spaces are coming to be recognised as health-promoting settings for general populations, little is understood about the use of nature contact in treatment and care for individuals experiencing ill-health.
Methods: This paper provides a summary of key research findings and presents a case study examining the self reported health and well-being benefits of nature contact for a small clinical sample. The 'Spectrum of Interventions for Mental Health Problems and Mental Disorders' provides a conceptual framework for ordering current and future information relating to nature-based interventions.
Results: Evidence demonstrates that separately, physical activity, social connection, and contact with nature enhance human health and well-being. The case example illustrates how 'active', 'social' and 'adventurous' contact with nature may be combined within a treatment intervention to protect and enhance the health of individuals experiencing chronic mental, emotional and physical health difficulties.
Conclusions: 'Contact with nature' constitutes a health promotion strategy with potential application in prevention, early intervention, treatment and care. Recommendations include further research to investigate the benefits of nature contact within existing interventions, and the impacts of 'active' and 'social' nature contact within tailored interventions for targeted individuals and communities.

The enormous human and economic costs associated with occupational stress suggest that initiatives designed to prevent and/or reduce employee stress should be high on the agenda of workplace health promotion (WHP) programmes. Although employee stress is often the target of WHP, reviews of job stress interventions suggest that the common approach to combating job stress is to focus on the individual without due consideration of the direct impacts of working conditions on health as well as the effects of working conditions on employees' ability to adopt and sustain ‘healthy’ behaviours. The purpose of the first part of this paper is to highlight the criticisms of the individual approach to job stress and to examine the evidence for developing strategies that combine both individual and organizational-directed interventions (referred to as the comprehensive approach). There is a risk that WHP practitioners may lose sight of the role that they can play in developing and implementing the comprehensive approach, particularly in countries where occupational health and safety authorities are placing much more emphasis on identifying and addressing organizational sources of job stress. The aim of the second part of this paper is therefore to provide a detailed description of what the comprehensive approach to stress prevention/reduction looks like in practice and to examine the means by which WHP can help develop initiatives that address both the sources and the symptoms of job stress.

Objective To pilot-test a brief written prescription recommending lifestyle changes delivered by general practitioners (GPs) to their patients.
Design The Active Nutrition Script (ANS) included five nutrition messages and personalised exercise advice for a healthy lifestyle and/or the prevention of weight gain. GPs were asked to administer 10 scripts over 4 weeks to 10 adult patients with a body mass index (BMI) of between 23 and 30 kg m− 2. Information recorded on the script consisted of patients' weight, height, waist circumference, gender and date of birth, type and frequency of physical activity prescribed, and the selected nutrition messages. GPs also recorded reasons for administering the script. Interviews recorded GPs views on using the script.
Setting General practices located across greater Melbourne.
Subjects and results Nineteen GPs (63% female) provided a median of nine scripts over 4 weeks. Scripts were administered to 145 patients (mean age: 54 ± 13.2 years, mean BMI: 31.7 ± 6.3 kg m− 2; 57% female), 52% of whom were classified as obese (BMI >30 kg m− 2). GPs cited ‘weight reduction’ as a reason for writing the script for 78% of patients. All interviewed GPs (90%, n = 17) indicated that the messages were clear and simple to deliver.
Conclusions GPs found the ANS provided clear nutrition messages that were simple to deliver. However, GPs administered the script to obese patients for weight loss rather than to prevent weight gain among the target group. This has important implications for future health promotion interventions designed for general practice.

OBJECTIVE: To report on a new modelling approach developed for the assessing cost-effectiveness in obesity (ACE-Obesity) project and the likely population health benefit and strength of evidence for 13 potential obesity prevention interventions in children and adolescents in Australia. METHODS: We used the best available evidence, including evidence from non-traditional epidemiological study designs, to determine the health benefits as body mass index (BMI) units saved and disability-adjusted life years (DALYs) saved. We developed new methods to model the impact of behaviours on BMI post-intervention where this was not measured and the impacts on DALYs over the child's lifetime (on the assumption that changes in BMI were maintained into adulthood). A working group of stakeholders provided input into decisions on the selection of interventions, the assumptions for modelling and the strength of the evidence. RESULTS: The likely health benefit varied considerably, as did the strength of the evidence from which that health benefit was calculated. The greatest health benefit is likely to be achieved by the 'Reduction of TV advertising of high fat and/or high sugar foods and drinks to children', 'Laparoscopic adjustable gastric banding' and the 'multi-faceted school-based programme with an active physical education component' interventions. CONCLUSIONS: The use of consistent methods and common health outcome measures enables valid comparison of the potential impact of interventions, but comparisons must take into account the strength of the evidence used. Other considerations, including cost-effectiveness and acceptability to stakeholders, will be presented in future ACE-Obesity papers. Information gaps identified include the need for new and more effective initiatives for the prevention of overweight and obesity and for better evaluations of public health interventions.

Buruli ulcer disease (BUD), a devastating tropical disease caused by Mycobacterium ulcerans, occurs in more than 80% of the administrative districts of Ghana. To elucidate community perceptions and
understanding of the aetiology of BUD, attitudes towards Buruli patients and treatment-seeking behaviours, we conducted a survey with 504 heads of households and seven focus group discussions in Ga West District, Ghana. Although 67% of participants regarded BUD as a health problem, 53% did not know its cause. Sixteen per cent attributed the cause to drinking non-potable water, 8.1% mentioned poor personal hygiene or dirty surroundings, and 5.5% identified swimming or wading in ponds as a risk factor. About 5.2% thought that witchcraft and curses cause BUD, and 71.8% indicated that BU sufferers first seek treatment from herbalists and only refer to the hospital as a last resort. The main
reasons were prospects of prolonged hospital stay, cost of transport, loss of earnings and opportunity associated with parents attending their children’s hospitalization over extended period, delays in being
attended by medical staff, and not knowing the cause of the disease or required treatment. The level of acceptance of BUD sufferers was high in adults but less so in children. The challenge facing health workers is to break the vicious cycle of poor medical outcomes leading to poor attitudes to hospital treatment in the community. Because herbalists are often the first people consulted by those who contract the disease, they need to be trained in early recognition of the pre-ulcerative stage of Buruli lesions.

New Australian government funding for the Better Outcomes in Mental Health Care initiative is a significant step forward for mental health, with general practitioners now able to offer direct referrals to psychologists, social workers, occupational therapists and Aboriginal health workers. Incentives for better teamwork between GPs and other mental health professionals have been introduced, but may have unintended consequences, including an exacerbation of workforce shortages in rural and remote areas. Possible solutions to these shortages include rural scholarships for students in the mental health professions; recruitment and retention of students coordinated by university departments of rural health; better access to continuing professional development; and federally funded rural positions and additional financial incentives for rural mental health practitioners.

The Australian community health sector has undergone extensive organisational reform in recent times, and, in the push to enhance efficiencies and contain costs, there are indications that these changes may have undermined the wellbeing of community health personnel and their ability to provide high quality illness-prevention services. The aim of this study was to examine the working environments experienced by community health service employees and identify conditions that are predictive of employee stress. The study was guided by a tailored version of the demand-control-support model, whereby the generic components of the model had been augmented by more situation-specific stressors. The results of multiple regression analyses indicated that job control, and, to a lesser extent, social support, were closely associated with the outcome variables (psychological health, job satisfaction and organisational commitment). The more situation-specific stressors also accounted for significant proportions of explained variance. Overall, the results suggest that working conditions, particularly job control, social support and specific job stressors, offer valuable opportunities for protecting and enhancingthe wellbeing of community health service personnel.

Obesity prevention programs are at last underway or being planned in Australia and New Zealand. However, it is imperative that they are well-evaluated so that they can contribute to continuous program improvement and add much-needed evidence to the international literature on what works and does not work to prevent obesity. Three critical components of program evaluation are especially at risk when the funding comes from service delivery rather than research sources. These are: the need for comparison groups; the need for measured height and weight; and the need for sufficient process and context information. There is an important opportunity to build collaborative mechanisms across community-based obesity prevention sites to enhance the program and evaluation quality and to accelerate knowledge translation into practice and policy.

Objectives: Stroke is the world’s second leading cause of death in people aged over 60 years. Approximately 50,000 strokes occur annually in Australia with numbers predicted to increase by about one third over 10-years. Our objectives were to assess the economic implications of a public health program for stroke by: (1) predicting what potential health-gains and cost-offsets could be achieved; and (2) determining the net level of annual investment that would offer value-for-money.
Methods: Lifetime costs and outcomes were calculated for additional cases that would benefit if ‘current practice’ was feasibly improved, estimated for one indicative year using: (i) local epidemiological data, coverage rates and costs; and (ii) pooled effect sizes from systematic reviews.
Interventions: blood pressure lowering; warfarin for atrial fibrillation; increased access to stroke units; intravenous thrombolysis and aspirin for ischemic events; and carotid endarterectomy. Value-for-money threshold: AUD$30,000/DALY recovered.
Results: Improved, prevention and management could prevent about 27,000 (38%) strokes in 2015. In present terms (2004), about 85,000 DALYs and AUD$1.06 billion in lifetime cost-offsets could be recovered. The net level of annual warranted investment was AUD$3.63 billion.
Conclusions: Primary prevention, in particular blood pressure lowering, was most effective. A public health program for stroke
is warranted

Iron deficiency anaemia is highly endemic in rural areas of Tanzania and in many developing countries. Its prevention among school children requires greater dissemination of knowledge of anaemia among children, teachers, parents and the general community. Associated improvements in the hygienic status of domestic and school environments are also often required. One-hundred-and-thirty-one anaemic children, 90 parents and 76 teachers were interviewed to ascertain their understanding of anaemia. Most children and parents had little knowledge of the symptoms, causes and prevention of anaemia. In addition to their iron-deficient diets, more than half of the children went to school without something to eat at breakfast and during school hours. However, parents and teachers were willing to work together to provide meals for the children. Poor sanitation in the children's homes and in schools was a little recognized factor which could pose a serious risk of anaemia. In addition, inadequate sanitation facilities and poor quality of physical environment prevailed both in the children's homes and in schools. The findings suggest the need for the establishment of a health-promoting schools network to provide a comprehensive framework for health promotion in schools as well as in homes in Tanzania and in other developing countries. Schools can be an ideal setting to positively influence a community's health status. Partnerships among teachers, parents and the wider community are required to identify, prioritize and ameliorate health problems.

Preventative health strategies incorporating the views of target participants have improved the likelihood of success. This qualitative study aimed to elicit child and parent views regarding social and environmental barriers to healthy eating, physical activity and child obesity prevention programmes, acceptable foci, and appropriate modes of delivery. To obtain views across a range of social circumstances three demographically diverse primary schools in Victoria, Australia were selected. Children in Grades 2 (aged 7–8 years) and 5 (aged 10–11 years) participated in focus groups of three to six children. Groups were semi-structured using photo-based activities to initiate discussion. Focus groups with established parent groups were also conducted. Comments were recorded, collated, and themes extracted using grounded theory. 119 children and 17 parents participated. Nine themes emerged: information and awareness, contradiction between knowledge and behaviour, lifestyle balance, local environment, barriers to a healthy lifestyle, contradictory messages, myths, roles of the school and family, and timing and content of prevention strategies for childhood obesity. In conclusion, awareness of food ‘healthiness’ was high however perceptions of the ‘healthiness’ of some sedentary activities that are otherwise of benefit (e.g. reading) were uncertain. The contradictions in messages children receive were reported to be a barrier to a healthy lifestyle. Parent recommendations regarding the timing and content of childhood obesity prevention strategies were consistent with quantitative research. Contradictions in the explicit and implicit messages children receive around diet and physical activity need to be prevented. Consistent promotion of healthy food and activity choices across settings is core to population prevention programmes for childhood obesity.

Schools are key settings for promoting the social and emotional health and well-being of children. This study investigated the effectiveness of interventions to improve the social and emotional well-being of primary school-aged children. The protocol development stage of the proposed systematic review identified related and comparable research reviews, indicating a more useful review of reviews. Eight reviews of intervention effectiveness covering 322 primary studies were reviewed. The majority examined classroom-based interventions. Greater effectiveness results from a sustained focus on the promotion of mental health, on self-esteem and coping outcomes within the broad school climate, and on replicating positive impacts rather than the prevention of mental health problems. Conclusions are limited by short duration of studies, lack of detail of interventions, identified outcomes and socio-demographic data, and the relationship between processes and outcomes. This study has clearly shown how crucial carefully designed studies are in understanding strategies with potential to impact on the mental health and well-being of children.

Background: Despite the fact that it is largely preventable, dental caries (decay) remains one of the most common chronic diseases of early childhood. Dental decay in young children frequently leads to pain and infection necessitating hospitalization for dental extractions under general anaesthesia. Dental problems in early childhood have been shown to be predictive of not only future dental problems but also on growth and cognitive development by interfering with comfort nutrition, concentration and school participation. Objective: To review the current evidence base in relation to the aetiology and prevention of dental caries in preschool-aged children. Methods: A search of MEDLINE, CINALH and Cochrane electronic databases was conducted using a search strategy which restricted the search to randomized controlled trials, meta-analyses, clinical trials, systematic reviews and other quasi-experimental designs. The retrieved studies were then limited to articles including children aged 5 years and under and published in English. The evidence of effectiveness was then summarized by the authors. Conclusions: The review highlighted the complex aetiology of early childhood caries (ECC). Contemporary evidence suggests that potentially effective interventions should occur in the first 2 years of a child's life. Dental attendance before the age of 2 years is uncommon; however, contact with other health professionals is high. Primary care providers who have contact with children well before the age of the first dental visit may be well placed to offer anticipatory advice to reduce the incidence of ECC.

Objective To explore the oral health beliefs and practices of primary health care professionals which may act as barriers to the development of a model of shared care for the oral health of pre-school children.
Design Qualitative focus group discussions and semi-structured interviews.
Setting Four rural local government areas in Victoria, Australia, 2003.
Subjects and methods Subjects: maternal and child health nurses, general medical practitioners, dental professionals and paediatricians working in the four local government areas. Data collection: discipline specific focus groups and semi-structured interviews. Data analysis: transcription, coding, clustering and thematic analysis.
Results Several strong themes emerged from the data. All participants agreed that dental caries is a significant health issue for young children and their families. Beliefs about the aetiology of dental caries and its prevention were variable and often simplistic, focusing predominantly on diet. Dental professionals did not believe that they had a primary role in the oral health of pre-school aged children but that others particularly maternal and child health nurses did. However other health care professionals were not confident in assuming this role.
Conclusions This study has identified important barriers and possible strategies for the development of an integrated and shared approach to preventing dental caries in pre-school aged children. Clear and consistent oral health information and agreed roles and responsibilities need to be developed.

Women and men are different as regards their biology, the roles and responsibilities that society assigns to them and their position in the family and community. These factors have a great influence on causes, consequences and management of diseases and ill-health and on the efficacy of health promotion policies and programmes. This is confirmed by evidence on male–female differences in cause-specific mortality and morbidity and exposure to risk factors. Health promoting interventions aimed at ensuring safe and supportive environments, healthy living conditions and lifestyles, community involvement and participation, access to essential facilities and to social and health services need to address these differences between women and men, boys and girls in an equitable manner in order to be effective. The aim of this paper is to (i) demonstrate that health promotion policies that take women's and men's differential biological and social vulnerability to health risks and the unequal power relationships between the sexes into account are more likely to be successful and effective compared to policies that are not concerned with such differences, and (ii) discuss what is required to build a multisectoral policy response to gender inequities in health through health promotion and disease prevention. The requirements discussed in the paper include i) the establishment of joint commitment for policy within society through setting objectives related to gender equality and equity in health as well as health promotion, ii) an assessment and analysis of gender inequalities affecting health and determinants of health, iii) the actions needed to tackle the main determinants of those inequalities and iv) documentation and dissemination of effective and gender sensitive policy interventions to promote health. In the discussion of these key policy elements, we use illustrative examples of good practices from different countries around the world.
