Prevalence, awareness, treatment, and control of hypertension in China data from the China National Nutrition and Health Survey 2002

Background— The present article aims to provide accurate estimates of the prevalence, awareness, treatment, and control of hypertension in adults in China.

Methods and Results— Data were obtained from sphygmomanometer measurements and an administered questionnaire from 141 892 Chinese adults 18 years of age who participated in the 2002 China National Nutrition and Health Survey. In 2002, 153 million Chinese adults were hypertensive. The prevalence was higher among men than women (20% versus 17%; P<0.001) and was higher in successive age groups. Overall, the prevalence of hypertension was higher in urban compared with rural areas in men (23% versus 18%; P<0.01) and women (18% versus 16%; P<0.001). Of the 24% affected individuals who were aware of their condition, 78% were treated and 19% were adequately controlled. Despite evidence to suggest improved levels of treatment in individuals with hypertension over the past decade, compared with estimates from 1991, the ratio of controlled to treated hypertension has remained largely unchanged at 1:4.

Conclusions— One in 6 Chinese adults is hypertensive, but only one quarter are aware of their condition. Despite increased rates of blood pressure–lowering treatment, few have their hypertension effectively controlled. National hypertension programs must focus on improving awareness in the wider community, as well as treatment and control, to prevent many tens of thousands of cardiovascular-related deaths.

Geelong community's priorities and expectations of public health care

Abstract This thesis set out to achieve the following objectives: (1) To identify the priorities and expectations that the Geelong community has of its public health care system. (2) To determine if there is a common view on the attributes of a just health system. (3) To consider a method of utilising the data in the determination of health care priority setting in Barwon Health. (4) To determine a model of community participation which enables ongoing input into the decision making processes of Barwon Health. The methodology involved a combination of qualitative and quantitative research. The qualitative work involved the use of focus groups that were conducted with 64 members of the Geelong community. The issues raised informed the development of the interview schedule that was the basis of the quantitative study, which surveyed a representative sample of 400 members of the Geelong community. Prior to reporting on this work, the areas of distributive justice, scarcity and community participation in health care were considered. The research found that timely access to public hospitals, emergency care and aged care services were the major priorities; for many people, the cost was less relevant than a quality service. Shorter waiting times and increased staffing levels were strongly supported. Increased taxes were nominated as the best means of financing the health system they sought. Community based services were less relevant than hospital services but health education was supported. An egalitarian approach to resource distribution was favoured although the community was prepared to discriminate in favour of younger people and against older people. There was strong support for the community to be involved in decision making in the public health care system through surveys or focus groups but very little support was given to priorities being determined by politicians, administrators and to a lesser extent, medical professionals.

Oddsocks at the Melbourne Fringe Festival : a methods paper for using an arts installation in promoting public health

Installation art involves using everyday objects and spaces in an unusual way to gain attention and encourage interaction. While arts-based projects have the ability to inform and provoke interest, few have focused on public health. Oddsocks was conceived as a public health installation as part of the annual Melbourne Fringe Festival, with a primary aim to raise awareness concerning the importance of exercise and foot health. Promoting such underserved public health issues creates specific challenges which have been typically under-reported. This methods paper focuses on how these challenges can be met through arts-based initiatives and arts-based inquiry.

Modelling the public health consequences of cannabis use in Australia

Aims: To detail and validate a simulation model that describes the dynamics of cannabis use, including its probable causal relationships with schizophrenia, road traffic accidents (RTA) and heroin/poly-drug use (HPU).

Methods: A Markov model with 17 health-states was constructed. Annual cycles were used to simulate the initiation of cannabis use, progression in use, reduction and complete remission. The probabilities of transition between health-states were derived from observational data. Following 10-year-old Australian children for 90 years, the model estimated age-specific prevalence for cannabis use. By applying the relative risks according to the extent of cannabis use, the age-specific prevalence of schizophrenia and HPU, and the annual RTA incidence and fatality rate were also estimated. Predictive validity of the model was tested by comparing modelled outputs with data from other credible sources. Sensitivity and scenario analyses were conducted to evaluate technical validity and face validity.

Results: The estimated cannabis use prevalence in individuals aged 10-65 years was 12.2% which comprised 27.4% weekly and 18.0% daily users. The modelled prevalence and age profile were comparable to the reported cross-sectional data. The model also provided good approximations to the prevalence of schizophrenia (Modelled: 4.75/1,000 persons vs Observed: 4.6/1,000 persons), HPU (3.2/1,000 vs 3.1/1,000) and the RTA fatality rate (8.1 per 100,000 vs 8.2 per 100,000). Sensitivity analyses and scenario analysis provided expected and explainable trends.

Conclusions: The validated model provides a valuable tool to assess the likely effectiveness and cost-effectiveness of interventions designed to affect patterns of cannabis use. It can be updated as new data becomes available and/or applied to other countries.

Raising the profile of public health ethics in Australia : time for debate

This paper argues for greater dialogue on public health ethics. There has been little discussion in Australia about the significant ethical dilemmas in this field, and there is no agreed framework for analysing and responding to these challenges. We highlight concerns about the suitability of biomedical principles-based ethics for public health, and encourage public health professionals in this country to reflect on ethical challenges in public health research. A focus on research ethics concerns will deliver concrete examples demonstrating the need for a public health ethics frame work. Recommendations are offered for how public health ethics promotion may occur locally.

Media reports of heroin overdose spates: public health messages, moral panics or risk advertisements?

This article reports on an investigation of the public health utility of media messages concerning spates (temporal clusters) of heroin-related overdose (HOD) from the perspective of some injecting drug users (IDUs). In-depth qualitative interviews were carried out with a convenience sample of 60 IDUs, in the setting of two Needle and Syringe Programs in an Australian regional city (Geelong) between April and May 2000. Very few interviewees reported that they had personally experienced a spate of overdoses. None of the interviewees reported communicating the existence of a killer batch to other IDUs. No interviewees reported having changed either their injecting practices or the amount of heroin they used following such a media alert. Indeed, a substantial minority of the interviewees reported seeking out these stronger batches and participant narratives illustrate that, for a substantial group of interviewees, the media reporting of a hypothetical 'killer batch' of heroin may have implications for their drug-seeking and health-related behaviour. It was found that the accuracy of information available to IDUs is mixed and that the flow of information within this social network was slow. Findings demonstrate that media reporting of killer batches of heroin has little value as a public health strategy and provide an example of how some activities that are proposed as public health measures may in fact have the opposite effect.

Physical activity, dietary change and weight control : a public health perspective

This study examined weight-control behaviour among Victorian adults, focusing specifically on physical activity and dietary fat-related behaviour and beliefs. It also explored barriers to changing diet and physical activity, and used common theories of behaviour change to identify factors that influence weight-control behaviour, weight change and perceived weight-control success.

Analysis of outsourcing in the Victorian public health sector

The research has uncovered a major reason for outsourcing in this sector as a desire to improve middle management, specifically their skill levels and familiarity with new operating procedures. Outsourcing negative outcomes were the result of decision-makers not considering the length of relationships between parties and the lack of information available to monitor quality and other contractual terms. Outsourcing has been performed for various reasons, but rarely have decision-makers considered the full range of factors that may potentially affect the optimal nature of the decision, or the organisational characteristics of their workplaces.

Climate change in the kitchen and on the public health agenda

Direct or indirect consequences of climate change on the vulnerable groups within communities are discussed. The health impacts of climate change will be felt in all facets of life and will be a significant challenge to public health systems and in health promotion fields.
