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 socio-economic 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.

A comparison of EQ-5D-3L population norms in Queensland, Australia, estimated using utility value sets from Australia, the UK and USA.

PURPOSE: To provide population norms for the EQ-5D-3L by age and gender based on a representative adult sample in Queensland, Australia; to assess differences in health-related quality of life by applying the Australian, UK and USA value sets to these data; and to assess differences in utility scores for key preventive health indicators. METHODS: A cross-sectional computer-assisted telephone interview survey (March-June 2011) with 5,555 adults. Respondents rated their impairment (none, moderate, severe problems) across five domains (mobility, self-care, usual activities, pain and discomfort, anxiety or depression) using the validated EQ-5D-3L health-related quality of life instrument. Utility score indexes were derived using the Australian, UK and USA value sets. RESULTS: Forty per cent of adults reported pain and discomfort while 3% indicated problems with self-care. Approximately one in six had limitations with mobility, usual activities or anxiety or depression. The three value sets performed similarly in discriminating differences based on most characteristics, and clinically meaningful differences were seen for age, body weight, physical activity and daily smoking. There were no differences in utility scores for gender. CONCLUSIONS: This is the first study to report general population findings for the Australian EQ-5D-3L value set. Overall, the Australian value set performed comparably with other value sets commonly used in the Australian population; however, differences were observed. Results will enable further refinement to health and economic studies in an Australian-specific context.

Summer of sorrow: measuring exposure to and impacts of trauma after Queensland's natural disasters of 2010-2011.

OBJECTIVES: To assess the population prevalence of property, income and emotional impacts of the 2010-2011 Queensland floods and cyclones. DESIGN, SETTING AND PARTICIPANTS: Cross-sectional telephone-based survey using a brief trauma exposure and impact screening instrument, conducted between 11 March and 6 June 2011, of 6104 adults who answered natural disaster and mental health questions. MAIN OUTCOME MEASURES: Natural disaster property damage exposure and emotional wellbeing impacts. RESULTS: Two-thirds of respondents (62%) reported being affected by the disasters, with property damage exposure ranging from 37.2% (suburb or local area) to 9.2% (own home, with 2.1% living elsewhere at least temporarily). Income was reduced for 17.0% of respondents and 11.7% of income-producing property owners reported damage to those properties. Trauma impacts ranged from 14.3% of respondents feeling "terrified, helpless or hopeless" to 3.9% thinking they might be "badly injured or die". Up to 5 months after the disasters, 7.1% of respondents were "still distressed" and 8.6% were "worried about how they would manage". Adults of working age and residents of regional and remote areas and of socioeconomically disadvantaged areas were disproportionately likely to report exposure to damage and emotional impacts. CONCLUSIONS: Weather-related disasters exact a large toll on the population through property damage and resultant emotional effects. Vulnerable subpopulations are more severely affected. There is a need for realistic, cost-effective and rapid-deployment mass interventions in the event of weather disasters.

Frequency of sunburn in Queensland adults: still a burning issue.

OBJECTIVE: To assess the current frequency of sunburn, a preventable risk factor for skin cancer, among Queensland adults. DESIGN AND SETTING: Cross-sectional population-based surveys of 16 473 residents aged ≥ 18 2013s across Queensland in 2009 and 2010. MAIN OUTCOME MEASURES: Proportion of the adult population reporting sunburn (skin reddening lasting 12 hours or more) during the previous weekend, by age, sex and other risk factors. RESULTS: One in eight men and one in 12 women in Queensland reported being sunburnt on the previous weekend. Age up to 65 2013s was the strongest predictor of sunburn: eg, people aged 18-24 2013s were seven times more likely (adjusted odds ratio [OR], 7.35; 95% CI, 5.09-10.62) and those aged 35-44 2013s were five times more likely (adjusted OR, 5.22) to report sunburn compared with those aged ≥ 65 2013s. Not having a tertiary education and being in the workforce were also significantly associated with sunburn. Those who had undertaken any physical activity the previous week were more likely to be sunburnt than those who were physically inactive. Sunburn was significantly less likely among people who generally took sun-protective measures in summer. Sunburn was not related to location of residence, socioeconomic disadvantage, skin colour, body weight or current smoking status. CONCLUSIONS: Sunburn remains a public health problem among Queensland residents, especially those under 45 2013s of age. Sun-safe habits reduce sunburn risk, but advice must be integrated with health promotion messages regarding physical activity to reduce the skin cancer burden while maintaining active wellbeing.

Revolting bodies, desiring lesbians: an introduction.

This introduction gives the background to this special issue of the Journal of Lesbian Studies that has its origin in the 18th Annual Lesbian Lives Conference of 2011. It traces the theme of Revolting Bodies: Desiring Lesbians across the ten articles of this collection and gives a brief summary of each.

Does physical activity increase the risk of unsafe sun exposure?

ISSUE ADDRESSED: Recent increases in the prevalence of self-reported participation in physical activity are encouraging and beneficial for health overall. However, the implications for sun safety need to be considered, particularly in Australia, which has the highest incidence of skin cancer in the world. This study investigated the relationship between physical activity and sunburn to determine if there is a need for integration of sun safety in physical activity promotion. METHODS: During the 2009/10 southern hemisphere summer, 7802 adults aged 18 to 74 years participated in a computer-assisted telephone interview survey which included a range of self-reported health measures including physical activity, sunburn, skin type, sun protection behaviour and demographic questions. Multivariate logistic regression modelling was undertaken to estimate the association between physical activity and sunburn. RESULTS: Those who reported doing any level of physical activity were significantly more likely to report having experienced sunburn in the past 12 months and on the last weekend, compared with those who did none, with the strongest association among those who undertook 7 hours or more. Each hour of physical activity was associated with a modest increase in the odds of experiencing sunburn in the previous 12 months (OR 1.02, 95% CI 1.010-1.037) and weekend (OR 1.04, 95% CI: 1.023-1.065), after adjusting for potential confounding variables. CONCLUSIONS: This study highlights the need for sun protection to be given more prominence in physical activity promotion in order to optimise health benefits without increasing the prevalence of sunburn and associated skin cancer risk.

Associations of body mass index and waist circumference with: energy intake and percentage energy from macronutrients, in a cohort of Australian children.

BACKGROUND: It is evident from previous research that the role of dietary composition in relation to the development of childhood obesity remains inconclusive. Several studies investigating the relationship between body mass index (BMI), waist circumference (WC) and/or skin fold measurements with energy intake have suggested that the macronutrient composition of the diet (protein, carbohydrate, fat) may play an important contributing role to obesity in childhood as it does in adults. This study investigated the possible relationship between BMI and WC with energy intake and percentage energy intake from macronutrients in Australian children and adolescents. METHODS: Height, weight and WC measurements, along with 24 h food and drink records (FDR) intake data were collected from 2460 boys and girls aged 5-17 years living in the state of Queensland, Australia. RESULTS: Statistically significant, yet weak correlations between BMI z-score and WC with total energy intake were observed in grades 1, 5 and 10, with only 55% of subjects having a physiologically plausible 24 hr FDR. Using Pearson correlations to examine the relationship between BMI and WC with energy intake and percentage macronutrient intake, no significant correlations were observed between BMI z-score or WC and percentage energy intake from protein, carbohydrate or fat. One way ANOVAs showed that although those with a higher BMI z-score or WC consumed significantly more energy than their lean counterparts. CONCLUSION: No evidence of an association between percentage macronutrient intake and BMI or WC was found. Evidently, more robust longitudinal studies are needed to elucidate the relationship linking obesity and dietary intake.

Guideline-discordant care in acute myocardial infarction: predictors and outcomes.

OBJECTIVES: To determine (i) factors which predict whether patients hospitalised with acute myocardial infarction (AMI) receive care discordant with recommendations of clinical practice guidelines; and (ii) whether such discordant care results in worse outcomes compared with receiving guideline-concordant care. DESIGN: Retrospective cohort study. SETTING: Two community general hospitals. PARTICIPANTS: 607 consecutive patients admitted with AMI between July 1997 and December 2000. MAIN OUTCOME MEASURES: Clinical predictors of discordant care; crude and risk-adjusted rates of inhospital mortality and reinfarction, and mean length of hospital stay. RESULTS: At least one treatment recommendation for AMI was applicable for 602 of the 607 patients. Of these patients, 411(68%) received concordant care, and 191 (32%) discordant care. Positive predictors at presentation of discordant care were age > 65 years (odds ratio [OR], 2.5; 95% CI, 1.7-3.6), silent infarction (OR, 2.7; 95% CI, 1.6-4.6), anterior infarction (OR, 2.5; 95% CI, 1.7-3.8), a history of heart failure (OR, 6.3; 95% CI, 3.7-10.7), chronic atrial fibrillation (OR, 3.2; 95% CI, 1.5-6.4); and heart rate >/= 100 beats/min (OR, 2.1; 95% CI, 1.4-3.1). Death occurred in 12.0% (23/191) of discordant-care patients versus 4.6% (19/411) of concordant-care patients (adjusted OR, 2.42; 95% CI, 1.22-4.82). Mortality was inversely related to the level of guideline concordance (P = 0.03). Reinfarction rates also tended to be higher in the discordant-care group (4.2% v 1.7%; adjusted OR, 2.5; 95% CI, 0.90-7.1). CONCLUSIONS: Certain clinical features at presentation predict a higher likelihood of guideline-discordant care in patients presenting with AMI. Such care appears to increase the risk of inhospital death.

An Australian comparison of specialist care of acute myocardial infarction.

OBJECTIVE: To determine whether patients hospitalized with acute myocardial infarction (AMI) in an Australian setting receive better pharmacological care if managed by cardiologists than by non-cardiologists. DESIGN: Retrospective chart review of patients hospitalized between 1 January 1997 and 30 June 1998, undertaken by abstractors blind to study objectives. SETTING: One tertiary and two community hospitals in south-east Queensland, Australia, in which all patients admitted with AMI were cared for by cardiologists and general physicians, respectively. STUDY PARTICIPANTS: Two cohorts of consecutive patients satisfying diagnostic criteria for AMI: 184 in the tertiary hospital and 207 in the community hospitals. MAIN OUTCOME MEASURES: Frequency of use, in highly eligible patients, of thrombolysis, beta-blockers, aspirin, angiotensin-converting enzyme (ACE) inhibitors, lipid-lowering agents, nitrates, and calcium antagonists. Cohorts were compared for differences in prognostic factors or illness severity. RESULTS: In community hospital patients, there was greater use of thrombolysis [100% versus 83% in the tertiary hospital; difference 17%, 95% confidence interval (CI) 11-26%; P < 0.001] and of ACE inhibitors (84% versus 66%; difference 18%, 95% CI 3-34%; P = 0.02), and lower median length of stay (6.0 days versus 7.0 days; P = 0.001) compared with tertiary hospital patients. Frequency of use of other drugs, and adjusted rates of death and re-infarction were the same for both cohorts. CONCLUSIONS: With respect to pharmacological management of patients hospitalized with AMI, cardiologists and general physicians appear to provide care of similar quality and achieve equivalent outcomes. Further studies are required to confirm the generalizability of these results to Australian practice as a whole.

Alternative antecedents, probabilities, and the suppression of fallacies in Wason's selection task.

Three experiments examined the influence of a second rule on the pattern of card selections on Wason's selection task. In Experiment 1 participants received a version of the task with a single test rule or one of two versions of the task with the same original test rule together with a second rule. The probability of q was manipulated in the two-rules conditions by varying the size of the antecedent set in the second rule. The results showed a significant suppression of q card and not-p card selections in the alternative-rule conditions, but no difference as a function of antecedent set size. In Experiment 2 the size of the antecendent set in the two-rules conditions was manipulated using the context of a computer printing double-sided cards. The results showed a significant reduction of q card selections in the two-rules conditions, but no effect of p set size. In Experiment 3 the scenario accompanying the rule was manipulated, and it specified a single alternative antecedent or a number of alternative antecedents. The q card selection rates were not affected by the scenario manipulation but again were suppressed by the presence of a second rule. Our results suggest that people make inferences about the unseen side of the cards when engaging with the task and that these inferences are systematically influenced by the presence of a second rule, but are not influenced by the probabilistic characteristics of this rule. These findings are discussed in the context of decision theoretic views of selection task performance (Oaksford & Chater, 1994).
