RESUMO
PURPOSE: People affected by cancer who live in rural Australia experience inferior survival compared to their urban counterparts. This study determines whether self-reported physical and mental health, as well as health-promoting behaviours, also differ between rural and urban Australian adults with a history of cancer. METHODS: Weighted, representative population data were collected via the South Australian Monitoring and Surveillance System between 1 January 2010 and 1 June 2015. Data for participants with a history of cancer (n = 4295) were analysed with adjustment for survey year, gender, age group, education, income, family structure, work status, country of birth and area-level relative socioeconomic disadvantage (SEIFA). RESULTS: Cancer risk factors and co-morbid physical and mental health issues were prevalent among cancer survivors regardless of residential location. In unadjusted analyses, rural survivors were more likely than urban survivors to be obese and be physically inactive. They were equally likely to experience other co-morbidities (diabetes, chronic obstructive pulmonary disease, cardiovascular disease, arthritis or osteoporosis). With adjustment for SEIFA, rural/urban differences in obesity and physical activity disappeared. Rural survivors were more likely to have trust in their communities, less likely to report high/very high distress, but equally likely to report a mental health condition, both with and without adjustment for SEIFA. CONCLUSIONS: There is a need for deeper understanding of the impact of relative socioeconomic disadvantage on health (particularly physical activity and obesity) in rural settings and the development of accessible and culturally appropriate interventions to address rural cancer survivors' specific needs and risk factors.

OBJECTIVE: To determine the level of community concern about future food supplies and perception of the importance placed on government regulation over the supply of environmentally friendly food and identify dietary and other factors associated with these beliefs in Western Australia. DESIGN: Data from the 2009 and 2012 Nutrition Monitoring Survey Series computer-assisted telephone interviews were pooled. Level of concern about the effect of the environment on future food supplies and importance of government regulating the supply of environmentally friendly food were measured. Multivariate regression analysed potential associations with sociodemographic variables, dietary health consciousness, weight status and self-reported intake of eight foods consistent with a sustainable diet. SETTING: Western Australia. SUBJECTS: Community-dwelling adults aged 18-64 years (nâ¯=â¯2832). RESULTS: Seventy nine per cent of Western Australians were 'quite' or 'very' concerned about the effect of the environment on future food supplies. Respondents who paid less attention to the health aspects of their diet were less likely than those who were health conscious ('quite' or 'very' concerned) (ORâ¯=â¯0.53, 95% CI [0.35, 0.8] and 0.38 [0.17, 0.81] respectively). The majority of respondents (85.3%) thought it was 'quite' or 'very' important that government had regulatory control over an environmentally friendly food supply. Females were more likely than males to rate regulatory control as 'quite' or 'very' important' (ORâ¯=â¯1.63, 95% CI [1.09, 2.44], pâ¯=â¯.02). Multiple regression modeling found that no other factors predicted concern or importance. CONCLUSIONS: There is a high level of community concern about the impact of the environment on future food supplies and most people believe it is important that the government regulates the issue. These attitudes dominate regardless of sociodemographic characteristics, weight status or sustainable dietary behaviours.

BACKGROUND: The reasons for low adherence to cereal dietary guidelines are not well understood but may be related to knowledge, attitudes, beliefs and perceived barriers. This study aims to assess trends in cereal foods consumption, intention to change and factors associated with intake among Western Australian (WA) adults 18 to 64 years. METHOD: Cross-sectional data from the 1995, 1998, 2001, 2004, 2009, and 2012 Nutrition Monitoring Survey Series involving 7044 adults were pooled. OUTCOME VARIABLES: types and amount of cereals (bread, rice, pasta, and breakfast cereal) eaten the day prior. Attitudes, knowledge, intentions, weight status and sociodemographic characteristics were measured. Descriptive statistics, multiple binary logistic and multinomial logistic regressions assess factors associated with consumption. RESULTS: Bread (78%) was the most commonly consumed cereal food. The proportion eating bread decreased across survey years (Odds Ratio OR = 0.31; 95% Confidence Interval; 0.24-0.40 in 2012 versus 1995), as did the amount (4.1 slices of bread in 1995 to 2.4 in 2012). The odds of consuming whole-grain cereal foods increased since 2009 (OR = 1.27; 1.02-1.58 versus 1995 p < 0.05). The likelihood of trying to eat less cereal food in the past year was greater in 2012 compared to 1995 (Relative Risk Ratio RRR 10.88; 6.81-17.4). Knowledge of cereal recommendations decreased over time (OR = 0.20; 0.15-0.27 in 2012 versus 1995 p < 0.001). Overweight and obese respondents were more likely than healthy weight respondents to have tried to eat less cereals (RRR 1.65; 1.22-2.24 and 1.88; 1.35-2.63 respectively). 'I already eat enough' was the main barrier (75% in 1995 to 84% in 2012 (p < 0.001)). CONCLUSIONS: WA adults are actively reducing the amount of cereal foods they eat and intake is associated with a misperception of adequacy of intake. Nutrition intervention is needed to increase awareness of the health benefits of cereal foods, particularly whole-grains, and to address barriers to incorporating them daily. TRIAL REGISTRATION: Not applicable.

BACKGROUND: Early adulthood represents the transition to independent living which is a period when changes in diet and body weight are likely to occur. This presents an ideal time for health interventions to reduce the effect of health problems and risk factors for chronic disease in later life. As young adults are high users of mobile devices, interventions that use this technology may improve engagement. The Connecting Health and Technology study aimed to evaluate the effectiveness of tailored dietary feedback and weekly text messaging to improve dietary intake of fruit, vegetables and junk food over 6 months among a population-based sample of men and women (aged 18-30 years). METHODS: A three-arm, parallel, randomized control trial was conducted. After baseline assessments, participants were randomized to one of three groups: A) dietary feedback and weekly text messages, B) dietary feedback only or C) control group. Dietary intake was assessed using a mobile food record App (mFR) where participants captured images of foods and beverages consumed over 4-days at baseline and post-intervention. The primary outcomes were changes in serves of fruits, vegetables, energy-dense nutrient-poor (EDNP) foods and sugar-sweetened beverages (SSB). The intervention effects were assessed using linear mixed effect models for change in food group serves. RESULTS: Young adults (n = 247) were randomized to group A (n = 82), group B (n = 83), or group C (n = 82). Overall, no changes in food group serves for either intervention groups were observed. An unanticipated outcome was a mean weight reduction of 1.7 kg (P = .02) among the dietary feedback only. Men who received dietary feedback only, significantly reduced their serves of EDNP foods by a mean of 1.4 serves/day (P = .02). Women who received dietary feedback only significantly reduced their intake of SSB (P = .04) by an average of 0.2 serves/day compared with controls. CONCLUSIONS: Tailored dietary feedback only resulted in a decrease in EDNP foods in men and SSB in women, together with a reduction in body weight. Using a mobile food record for dietary assessment and tailored feedback has great potential for future health promotion interventions targeting diet and weight in young adults.

PURPOSE: Resistance exercise is promoted in older adults for its ability to improve muscle mass, strength and, hence, in reducing falls. However, its effects on blood lipids and CVD risk are less well established, particularly in this age group. This study aimed to investigate whether a 1-year resistance exercise program improves lipid profile and chylomicron concentration in older men. METHODS: Participants were randomised to either three, 1 h resistance training sessions per week (RE) or an active control group [asked to undertake three 30 min walking sessions per week (AC)]. Fasting blood samples were collected at 0, 6, and 12 months for determination of lipid profile and glycaemic control. Diet, morphological and activity data were also collected at these time points. RESULTS: Following 12 months, the RE intervention group had greater improvements in cholesterol profile; LDL-cholesterol concentration significantly decreased by 0.2 (0.2) mM [mean (SEM)] compared to control (P < 0.05). The RE group also exhibited a significant increase in lean body mass of 0.9 (1.3) kg after 12 months compared to the AC group (P < 0.05). There was no treatment or time effect on other anthropometric measures or fasting triacylglycerol, glucose, insulin or chylomicron concentrations. CONCLUSION: The observed improvements in lean body mass and cholesterol profile promote the implementation of a resistance exercise intervention in this population.

BACKGROUND: Protein may play a role in preventing muscle loss with aging. To our knowledge, there have been no long-term randomized controlled trials to examine the effects of increased dietary protein intake on muscle health in community-dwelling older women. OBJECTIVE: In this study, we evaluated the effects of whey protein supplementation on muscle mass and physical function in community-dwelling older Australian women. METHODS: In this 2 y randomized, double-blind, placebo-controlled trial, women aged 70-80 y (mean 74.3 ± 2.7 y) were randomly assigned to either a high protein drink containing 30 g of whey protein (n = 109) or a placebo drink containing 2.1 g protein (n = 110) daily. Dual-energy X-ray absorptiometry appendicular skeletal muscle mass, upper arm and calf (38% tibia) muscle cross-sectional area, physical function including hand grip strength, lower limb muscle strength and Timed Up and Go test, and 24 h urinary nitrogen were measured at baseline, 1 y, and 2 y. RESULTS: A total of 196 women with at least one follow-up measurement were included in this analysis. Baseline mean BMI was 26.7 ± 3.9 kg/m(2) and protein intake was 76 ± 17 g/d (1.1 ± 0.3 g · kg body weight(-1) · d(-1)). A mean increase in protein intake of â¼ 20 g/d in the protein group was confirmed by the estimates from 24 h urinary nitrogen. Over the 2 y in both groups there was a significant decrease in the upper arm (mean ± SE: -5.59 ± 0.75 cm(2)) and calf (-0.77 ± 0.11 cm(2)) muscle area, as well as hand grip strength (-1.30 ± 0.3 kg) (all P < 0.05), but appendicular skeletal muscle mass did not change significantly. There were no significant effects of the protein intervention on any of the muscle mass or physical function measures (all P > 0.05) at 1 and 2 y. CONCLUSION: This study showed that in protein-replete, healthy, ambulant, postmenopausal older women, 30 g/d of extra protein did not improve the maintenance of muscle mass or physical function despite evidence of deterioration in muscle measurements in the upper limb. This trial was registered at the Australian New Zealand Clinical Trials Registry as ACTRN012607000163404.

BACKGROUND: The Internet contains a plethora of nutrition information. Health organizations are increasingly using the Internet to deliver population-wide health information and interventions. Effective interventions identify their target population and their needs; however, little is known about use of the Internet as a source of nutrition information. OBJECTIVE: The aim was to assess the change in prevalence and demographic characteristics of Western Australian adults accessing the Internet as a source of nutrition information and identify specific information needs. METHODS: Data were pooled from the Western Australian Department of Health's 3-yearly Nutrition Monitoring Survey Series telephone survey between 1995 and 2012 of 7044 participants aged 18 to 64 years. Outcome variables were the main sources of nutrition information used in the last year and yes/no responses to 4 suggestions to what would make it easier to eat a healthy diet. Sociodemographic variables were collected. RESULTS: The proportion of respondents using the Internet for nutrition information increased from <1% in 1995-2001 to 9.1% in 2004 and 33.7% in 2012. Compared to 2004, logistic regression showed that the odds of using the Internet for this information increased significantly in 2009 (OR 2.84, 95% CI 2.07-3.88) and 2012 (OR 5.20, 95% CI 3.86-7.02, P<.001). Respondents using the Internet as a source were more likely to be female (OR 1.30, 95% CI 1.05-1.60, P=.02), live in a metropolitan area (OR 1.26, 95% CI 1.03-1.54, P=.03), born in countries other than Australia/UK/Ireland (OR 1.41, 95% CI 1.07-1.85, P=.02), more educated (university: OR 2.46, 95% CI 1.77-3.42, P<.001), and were less likely to be older (55-64 years: OR 0.38, 95% CI 0.25-0.57, P<.001). The majority of respondents agreed the following information would assist them to make healthier choices: more ways to prepare healthy foods (72.0%, 95% CI 70.7-73.3), quicker ways to prepare healthy foods (79.0%, 95% CI 77.8-80.1), how to choose healthy foods (68.8%, 95% CI 67.5-70.1), and knowing more about cooking (54.7%, 95% CI 53.3-56.1). Those using the Internet for nutrition information were more likely than nonusers to want to know quicker ways to prepare healthy foods (83.0% vs 78.1%, P=.005) and information on choosing healthy foods (76.3% vs 67.3%, P<.001). CONCLUSIONS: Use of the Internet as a main source of nutrition information has grown rapidly since 2004; one-third of Western Australian adults reported using the Internet for this purpose in 2012. Information on preparing healthy foods (ideas, quicker ways), choosing ingredients, and knowing more about cooking would make it easier to eat a healthy diet. For Internet users, emphasis should be on quicker ways and choosing ingredients. These finding have implications for policy makers and practitioners and suggest that traditional health promotion tactics should continue to be used to reach the broader population.

BACKGROUND: Although (general practitioners) GPs have a role in managing patients with advanced cancer, little is known about their referral decisions. AIM: The aim of this study was to explore, using structured vignettes, how GPs might manage patients presenting with advanced cancer. DESIGN: A self-administered survey consisting of structured vignettes was administered to GPs in Australia. Fifty-six vignettes describing patients who may benefit from palliative care and/or treatment were constructed encompassing seven advanced cancer diagnoses (cerebral metastasis, lung metastases, renal cancer, bone metastases, ulcerating skin metastases, spinal metastases and stridor) and three clinical variables (age, prognosis and mobility). Seven vignettes were presented to each respondent. Respondents were asked if they would refer the patient and the benefits of different treatment modalities. Participant responses were compared with responses provided by an expert panel. Logistic regression and parametric tests were used to estimate odds of referral. SETTING/PARTICIPANTS: The respondents were GPs, currently registered and practicing in Australia. Participants were selected randomly from a national list of practitioners. RESULTS: Four hundred and seven questionnaires were received. There was wide variation (31%-97%) in the proportion of respondents who agreed with the expert panel. The odds of referral for radiotherapy varied the most. Significant predictive variables included patient age, mobility and prognosis and respondent demographics. CONCLUSION: GPs' referral decisions for patients with advanced cancer appear to deviate from expert opinion and can be predicted using respondent and patient characteristics. If these data were reflected in clinical practice some patients may not be offered helpful palliative treatment options.

OBJECTIVE: To explore factors associated with self-reported food poisoning among Western Australian adults between 1998 and 2009. DESIGN: Data were pooled from four Nutrition Monitoring Surveys Series which included information on suspected food poisoning among Western Australian adults. Descriptive statistics and multinomial regression analyses were used to describe factors associated with self-reported food poisoning, food safety knowledge and behaviours. SETTING: Population of Western Australia estimated to be 2·5 million in 2009. SUBJECTS: A representative sample of 4494 adults aged between 18 and 64 years. RESULTS: There was no significant change in self-reported food poisoning over time, with about 18 % saying they had suspected food poisoning in the last 6 months. Overall, 2·1% said they had confirmed their food-borne illness with a nurse of doctor. People less than 34 years old, those with a university degree and people who ate meals out on the day prior to the survey (one meal: OR = 1·30, 95% CI 1·04, 1·62; two meals: OR = 2·21, 95% CI 1·30, 3·76) were the most likely to report food poisoning. Younger people were also more likely to have their food poisoning confirmed by a health professional. Use of refrigerator thermometers and cool bags for storing food increased significantly between 2004 and 2009. CONCLUSIONS: Findings support the inclusion of food safety advice in dietary recommendations. Food safety and handling education and training is recommended for food businesses, particularly the takeaway food sector, and for consumers. Because food poisoning is reported more often by younger people, food safety education should begin during childhood.

BACKGROUND: Patients treated for prostate cancer may present to general practitioners (GPs) for treatment follow up, but may be reticent to have their consultations recorded. Therefore the use of simulated patients allows practitioner consultations to be rated. The aim of this study was to determine whether the speciality of the assessor has an impact on how GP consultation performance is rated. METHODS: Six pairs of scenarios were developed for professional actors in two series of consultations by GPs. The scenarios included: chronic radiation proctitis, Prostate Specific Antigen (PSA) 'bounce', recurrence of cancer, urethral stricture, erectile dysfunction and depression or anxiety. Participating GPs were furnished with the patient's past medical history, current medication, prostate cancer details and treatment, details of physical examinations. Consultations were video recorded and assessed for quality by two sets of assessors- a team of two GPs and two Radiation Oncologists deploying the Leicester Assessment Package (LAP). LAP scores by the GPs and Radiation Oncologists were compared. RESULTS: Eight GPs participated. In Series 1 the range of LAP scores by GP assessors was 61%-80%, and 67%-86% for Radiation Oncologist assessors. The range for GP LAP scores in Series 2 was 51%- 82%, and 56%-89% for Radiation Oncologist assessors. Within GP assessor correlations for LAP scores were 0.31 and 0.87 in Series 1 and 2 respectively. Within Radiation Oncologist assessor correlations were 0.50 and 0.72 in Series 1 and 2 respectively. Radiation Oncologist and GP assessor scores were significantly different for 4 doctors and for some scenarios. Anticipatory care was the only domain where GPs scored participants higher than Radiation Oncologist assessors. CONCLUSION: The assessment of GP consultation performance is not consistent across assessors from different disciplines even when they deploy the same assessment tool.

BACKGROUND: Men who have been treated for prostate cancer in Australia can consult their general practitioner (GP) for advice about symptoms or side effects at any time following treatment. However, there is no evidence that such men are consistently advised by GPs and patients experience substantial unmet need for reassurance and advice. OBJECTIVE: The intent of the study was to evaluate a brief, email-based educational program for GPs to manage standardized patients presenting with symptoms or side effects months or years after prostate cancer treatment. METHODS: GPs viewed six pairs of video vignettes of actor-patients depicting men who had been treated for prostate cancer. The actor-patients presented problems that were attributable to the treatment of cancer. In Phase 1, GPs indicated their diagnosis and stated if they would prescribe, refer, or order tests based on that diagnosis. These responses were compared to the management decisions for those vignettes as recommended by a team of experts in prostate cancer. After Phase 1, all the GPs were invited to participate in an email-based education program (Spaced Education) focused on prostate cancer. Participants received feedback and could compare their progress and their performance with other participants in the study. In Phase 2, all GPs, regardless of whether they had completed the program, were invited to view another set of six video vignettes with men presenting similar problems to Phase 1. They again offered a diagnosis and stated if they would prescribe, refer, or order tests based on that diagnosis. RESULTS: In total, 64 general practitioners participated in the project, 57 GPs participated in Phase 1, and 45 in Phase 2. The Phase 1 education program was completed by 38 of the 57 (59%) participants. There were no significant differences in demographics between those who completed the program and those who did not. Factors determining whether management of cases was consistent with expert opinion were number of sessions worked per week (OR 0.78, 95% CI 0.67-0.90), site of clinical practice (remote practice, OR 2.25, 95% CI 1.01-5.03), number of patients seen per week (150 patients or more per week, OR 10.66, 95% CI 3.40-33.48), and type of case viewed. Completion of the Spaced Education did impact whether patient management was consistent with expert opinion (not completed, OR 0.88, 95% CI 0.5-1.56). CONCLUSIONS: The management of standardized patients by GPs was particularly unlikely to be consistent with expert opinion in the management of impotence and bony metastasis. There was no evidence from this standardized patient study that Spaced Education had an impact on the management of patients in this context. However, the program was not completed by all participants. Practitioners with a greater clinical load were more likely to manage cases as per expert opinion.

BACKGROUND: There has been a focus recently on the use of the Internet and email to deliver education interventions to general practitioners (GPs). The treatment of breast cancer may include surgery, radiotherapy, chemotherapy, and/or hormone treatment. These treatments may have acute adverse effects. GPs need more information on the diagnosis and management of specific adverse effects encountered immediately after cancer treatment. OBJECTIVE: The goal was to evaluate an Internet-based educational program developed for GPs to advise patients with acute adverse effects following breast cancer treatment. METHODS: During phase 1, participants viewed 6 video vignettes of actor-patients reporting 1 of 6 acute symptoms following surgery and chemotherapy and/or radiotherapy treatment. GPs indicated their diagnosis and proposed management through an online survey program. They received feedback about each scenario in the form of a specialist clinic letter, as if the patient had been seen at a specialist clinic after they had attended the GP. This letter incorporated extracts from local guidelines on the management of the symptoms presented. This feedback was sent to the GPs electronically on the same survey platform. In phase 2, all GPs were invited to manage similar cases as phase 1. Their proposed management was compared to the guidelines. McNemar test was used to compare data from phases 1 and 2, and logistic regression was used to explore the GP characteristics that were associated with inappropriate case management. RESULTS: A total of 50 GPs participated. Participants were younger and more likely to be female than other GPs in Australia. For 5 of 6 vignettes in phase 1, management was consistent with expert opinion in the minority of cases (6%-46%). Participant demographic characteristics had a variable effect on different management decisions in phase 1. The variables modeled explained 15%-28% of the differences observed. Diagnosis and management improved significantly in phase 2, especially for diarrhea, neutropenia, and seroma sample cases. The proportion of incorrect management responses was reduced to a minimum (25.3%-49.3%) in phase 2. CONCLUSIONS: There was evidence that providing feedback by experts on specific cases had an impact on GPs' knowledge about how to appropriately manage acute treatment adverse effects. This educational intervention could be targeted to support the implementation of shared care during cancer treatment.

BACKGROUND: There is unequal access to health care in Australia, particularly for the one-third of the population living in remote and rural areas. Video consultations delivered via the Internet present an opportunity to provide medical services to those who are underserviced, but this is not currently routine practice in Australia. There are advantages and shortcomings to using video consultations for diagnosis, and general practitioners (GPs) have varying opinions regarding their efficacy. OBJECTIVE: The aim of this Internet-based study was to explore the attitudes of Australian GPs toward video consultation by using a range of patient scenarios presenting different clinical problems. METHODS: Overall, 102 GPs were invited to view 6 video vignettes featuring patients presenting with acute and chronic illnesses. For each vignette, they were asked to offer a differential diagnosis and to complete a survey based on the theory of planned behavior documenting their views on the value of a video consultation. RESULTS: A total of 47 GPs participated in the study. The participants were younger than Australian GPs based on national data, and more likely to be working in a larger practice. Most participants (72%-100%) agreed on the differential diagnosis in all video scenarios. Approximately one-third of the study participants were positive about video consultations, one-third were ambivalent, and one-third were against them. In all, 91% opposed conducting a video consultation for the patient with symptoms of an acute myocardial infarction. Inability to examine the patient was most frequently cited as the reason for not conducting a video consultation. Australian GPs who were favorably inclined toward video consultations were more likely to work in larger practices, and were more established GPs, especially in rural areas. The survey results also suggest that the deployment of video technology will need to focus on follow-up consultations. CONCLUSIONS: Patients with minor self-limiting illnesses and those with medical emergencies are unlikely to be offered access to a GP by video. The process of establishing video consultations as routine practice will need to be endorsed by senior members of the profession and funding organizations. Video consultation techniques will also need to be taught in medical schools.

This study investigated time trends and latitude differentials in the thickness distributions of invasive melanomas diagnosed in Australia between 1990 and 2006 using data from population-based cancer registries. Trends in incidence rates were calculated by sex, age group, thickness, year at diagnosis and latitude. For thin (<1.00 mm) melanomas the increase was very pronounced during the early 1990s (1990-1996, annual percentage change and 95% confidence interval: males +5.6(+3.5,+7.7); females +4.1(+1.7,+6.5), but then incidence rates became stable among both males (+0.6(-0.1,+1.4)) and females (-0.0(-0.9,+0.9)) of all ages between 1996 and 2006. In contrast, incidence of thick (>4.00 mm) melanomas continued to increase over the entire period (males +2.6(+1.9,+3.4); females +1.6(+0.6,+2.6)). Recent reductions in the incidence of thin melanomas were observed among young (<50 years) males and females, contrasted by an increase in thin melanomas among older people, and increases in thick melanomas among most age groups for males and elderly (75+) females. A strong latitude gradient in incidence rates was observed, with rates being highest in northern, more tropical areas and lowest in the most southern regions. However, the magnitude of the increase in thick melanomas was most pronounced in southern parts of Australia. The observed trends in thin melanomas can most likely be attributed to the impact of early detection and skin awareness campaigns. However, these efforts have not impacted on the continued increase in the incidence of thick melanomas, although some increase may be due to earlier detection of metastasising melanomas. This highlights the need for continued vigilance in early detection processes.

OBJECTIVE: Cancer survivor identity has become a dominant paradigm in describing people with cancer and in driving the focus of programmes and research in supportive care. This study investigated antecedents of survivor identity adoption and population-based prevalence. METHODS: A prospective survey of a population-based sample of 1966 (57% response) patients with colorectal cancer assessed socio-demographic variables, health behaviours, optimism, benefit finding, cancer threat appraisal, psychological distress and satisfaction with life at 5 months post-diagnosis as predictors of survivor identity 5 years subsequently. Prevalence of survivor identity at 5 years post-diagnosis and psychological and lifestyle outcomes (n = 786) were later assessed. RESULTS: Fifty-five per cent of people identified as a cancer survivor, 39.4% as a person who had had (or has) cancer, 1.4% as a cancer patient and 1.2% as a cancer victim. People who were older and who reported higher personal growth after diagnosis were more likely to assume a survivor identity at 5 years. At 5 years, survivors had higher benefit finding and better satisfaction with life. Cancer survivors uniquely reported a significant decrease in somatization and acceptance, and increases in satisfaction with life and physical activity over time. CONCLUSIONS: For patients with colorectal cancer, the cancer survivor identity is common but not universal 5 years after diagnosis; and may evolve from looking for benefit after cancer through personal growth. People who adopt a cancer survivor identity report more positive adjustment outcomes after cancer and this has implications for the design of clinical and community support interventions.

Short-term randomised, controlled trials have found that dietary protein relative to carbohydrate can reduce blood pressure. Our objective was to investigate the effects on blood pressure of an increase in protein intake from whey over 2 years in women aged over 70 years. From the general population, 219 women aged between 70 and 80 years were recruited to a 2-year randomised, double-blind, placebo-controlled parallel-design trial: 181 women completed the trial to the end of year 2. Participants were randomly assigned to consume a daily whey protein-based beverage (protein) or an energy-matched low-protein high-carbohydrate beverage (control). Blood pressure measurements were performed at baseline, year 1 and year 2. For protein relative to control, the estimated mean net differences in protein and carbohydrate intakes were 18 (95 % CI 13, 23) and -22 (95 % CI -9, -35) g/d at year 1, and 22 (95 % CI 17, 28) and -18 (95 % CI -6, -31) g/d at year 2. Intention-to-treat analysis found no overall differences between groups in blood pressure (P>0·5). Net differences in systolic and diastolic blood pressure were -2·3 (95 % CI -5·3, 0·7) and -1·5 (95 % CI -3·6, 0·6) mmHg at year 1, and 1·6 (95 % CI -1·5, 4·7) and 0·3 (95 % CI -1·9, 2·4) mmHg at year 2. Similar differences in systolic and diastolic blood pressure at years 1 and 2 were observed with per-protocol analysis. Therefore, the present study did not provide evidence that a higher whey protein intake in older women can have prolonged effects on blood pressure.

OBJECTIVE: To estimate the number of cancers to be diagnosed in 2025 that could be prevented solely due to changes in diet and physical activity. DESIGN AND SETTING: We used an Australian population-based cancer database to estimate the total number of cancers to be diagnosed in 2025, by applying published age- and sex-specific population projections to current cancer incidence rates, and multiplying the projected numbers of cancers by estimates of population-attributable fractions. MAIN OUTCOME MEASURES: Projected number of preventable cancers that would be diagnosed in 2025. RESULTS: Our projections suggest that there will be about 170, 000 Australians diagnosed with cancer in 2025. This represents an increase of about 60% on the 2007 incidence. Almost 43, 000 of these cancers (low estimate, 42,295; middle, 42,657; high, 43,990) could be prevented through improvements to diet and physical activity levels, including through their impact on obesity. It is likely that this is an underestimate of the true figure. The most preventable cancer types in 2025 were estimated to be bowel cancer and female breast cancer (10, 049 and 7273 preventable cases, respectively). CONCLUSIONS: About 25% of cancers, or about 43,000 cancers in 2025, can potentially be prevented through improvements in diet and physical activity. It is imperative that governments, clinicians and researchers act now if we are to reduce the significant future human and financial burden of cancer.

PURPOSE: Long-term (≥5 years) quality of life after colorectal cancer is not well described. The present study assessed quality of life (QOL) and psychological distress in colorectal cancer survivors more than 5 years to describe changes over time and antecedents of long-term outcomes. METHOD: A prospective survey of a population-based sample of 763 colorectal cancer patients assessed socio-demographic variables, health behaviors, optimism, threat appraisal, and perceived social support at 5 months post-diagnosis as predictors of QOL and psychological distress 5 years post-diagnosis. RESULTS: QOL improved over time (P < 0.01 for each measure); however, measures of psychological distress remained stable (P > 0.07 for each measure). Risk factors for poorer QOL and/or greater psychological distress included: later stage disease, having a permanent stoma, rectal cancer, fatigue, smoking, being single, low social support, low optimism, and a more negative cancer threat appraisal. Being women, having a pet, having a private health insurance, and receiving both surgery and adjuvant treatment were protective. CONCLUSION: Consistent with response shift theory, the antecedents of QOL after colorectal cancer are multifactorial and include predisposing socio-demographic, medical, and psychological variables. Psychosocial interventions that target both social support and threat appraisal may be effective for this patient group. Additional stepped-up support may be needed for people from a poorer social environment who have multiple risk factors for poorer adjustment. Health system effects require further investigation.

BACKGROUND: It is now common practice for doctors to consult patients by means other than face-to-face, often appearing before the patient on a computer screen. Also, many websites are using depictions of health professionals to increase the credibility of their services. Being trustworthy is an essential attribute for successful ehealth services. Little is known about which depicted accessories make a health professional appear more trustworthy. OBJECTIVE: To estimate the odds of an individual on-screen being rated trustworthy when viewed in a static image holding or wearing specific items of medical equipment. METHODS: We surveyed consecutive people attending community pharmacies to collect prescriptions in Western Australia. Respondents were presented with a series of 10 photographs, generated at random, of a man with varying numbers and combinations of medical equipment: stethoscope, reflex hammer, surgical scrubs, otoscope, and pen. They were then invited to rate the man as honest, trustworthy, honorable, moral, ethical, or genuine, or a combination of these, on the Source Credibility Scale. RESULTS: A total of 168 of 250 people gave informed consent, for a participation rate of 67.2%. There were 102 female and 66 male respondents. Of the 168 respondents, 96 (57%) were born in Australia and 102 (60.7%) were attending medical practices with more than one general practitioner. The mean age of respondents was 47 (SD 16) years (range 26-92 years). When only 1 item was present in an image, the stethoscope was associated with the highest odds for the person being considered honest (odds ratio [OR] 2.6, 95% confidence interval [CI] 1.6-4.3), trustworthy (OR 2.3, 95% CI 1.4-3.8), honorable (OR 2.7, 95% CI 1.6-4.5), moral (OR 2.4 95% CI 1.4-4.1), ethical (OR 2.6, 95% CI 1.5-4.6), and genuine (OR 1.8, 95% CI 1.0-3.1). The presence of a stethoscope increased the odds of the person being rated in a positive light in all photographs in which it was included. CONCLUSIONS: When an individual is portrayed in a static image, concurrent presentation of 3 or more items of medical equipment, and especially a stethoscope, is likely to exert a positive influence on the viewers' perceptions of the qualities of the person depicted.

AIM: To develop a tool to assist community pharmacists to triage patients presenting with cough and to validate this against an established cough-specific quality of life (QoL) measure. METHODS: A decision-support tool, the Pharmacy Cough Assessment Tool (PCAT) was developed with reference to published guidelines and a team of clinical experts. The PCAT was validated against the Leicester Cough Questionnaire (LCQ). It was then administered at four community pharmacies in Perth, Western Australia to assess the scope to recruit and follow up participants, and to estimate the proportion of participants who would be advised to consult a general practitioner (GP). The reported outcomes of the consultations with doctors were also recorded. RESULTS: Ninety-nine subjects were recruited over 12 weeks. Thirty-seven participants were advised to consult a GP for further assessment with reference to the PCAT; seven attended their doctor. The LCQ scores of those referred to their GP were significantly lower, indicating a poorer quality of life (adjusted mean and range 13.16 [11.87, 14.46]; non-referred 15.82 [14.47, 17.18]; P < 0.001). Scores of this magnitude have previously been shown to identify patients with chronic respiratory conditions. A smaller group of participants also had a poor quality of life based on LCQ scores but were not referred to their GP. Of the seven participants who made an appointment with their GP, most were prescribed treatment or referred for investigation. There was no significant difference in LCQ score based on gender, or decision to consult a GP. CONCLUSIONS: The PCAT identifies patients with cough who might benefit from medical advice and may feasibly be used as an initial screening tool in the community pharmacy setting.
