Psychological distress among Indigenous Australian cancer survivors.

PURPOSE: The purpose of this study is to identify the level of and factors associated with distress in 155 Indigenous Australian cancer survivors approximately 6 months post-diagnosis. METHODS: The distress thermometer (DT) was used to assess clinically significant distress (defined as having a DT score ≥ 4). Logistic regression was used to identify sociodemographic and clinical factors associated with clinically significant distress. RESULTS: The mean distress score was 2.7 (SD 2.9), with about one in three Indigenous cancer survivors reporting clinically significant distress (35%; n = 54). After adjusting for age and sex, clinically significant distress was more likely among those who were separated/divorced/widowed than those who were married (odds ratio (OR) = 2.99, 95% confidence intervals (95% CI) 1.21-7.35, p = 0.017) and less likely among those residing in remote areas than those in major cities (OR = 0.23, 95% CI 0.08-0.71, p = 0.001) and in those receiving non-surgical treatment only compared with surgery only (OR = 0.24, 95% CI 0.08-0.68, p = 0.008). CONCLUSIONS: Despite increased screening for distress in cancer care, this is, to our knowledge, the first published assessment of distress among Indigenous Australian cancer survivors. The characteristics of Indigenous cancer survivors associated with greater likelihood of clinically significant distress indicate at-risk subgroups who would benefit from screening and early intervention. Further research is required to identify the specific aetiologies of distress. Our findings indicate a need to identify psychological distress and for survivorship care to include culturally sensitive and tailored psychological support for Indigenous cancer survivors.

Lessons learned from a pilot study of an Indigenous patient navigator intervention in Queensland, Australia.

Indigenous patient navigator (IPN) programmes show promise in addressing barriers to cancer care and facilitation of patient self-efficacy. The purpose of this paper is to describe and reflect upon the experience of training an IPN and implementation of the intervention in the Australian context with Indigenous cancer patients. Randomised clinical trial might provide the best available evaluation measure of an intervention but caution should be taken in the implementation process. Socio-cultural aspects and training can affect the conduct of this type of intervention. We report here five issues needing consideration prior to implementing such intervention. Specifically: (1) recognition of the collective bonds within Indigenous community and understanding by IPN of the degree of personal assistance perceived as not intrusive by the patient; (2) conduct ongoing evaluation of the different role of an IPN involved in this intervention care provider vs. researcher. (3) meaningful engagement develops from a trusting/collaborative relationship between research team and study site staff which may not occur in the study time frame; (4) existing skills as well as training provided may not translate in the IPN understanding and aligning with the study objectives/research values; (5) recruitment of participants requires innovative and highly flexible strategies to be successful.

Follow-up cancer care: perspectives of Aboriginal and Torres Strait Islander cancer survivors.

PURPOSE: The purpose of this study was to explore Indigenous Australian cancer survivors' perspectives of follow-up cancer care and management.. METHODS: This is a qualitative study employing individual interviews with 21 Indigenous cancer survivors (13 females, 8 males) recruited from a rural primary health service and large tertiary hospital in Brisbane, Queensland. Yarning methods were used to conduct semi-structured interviews. Yarning is a culturally appropriate, informal conversational process emphasising the importance of storytelling. RESULTS: Findings describe a range of ways in which follow-up cancer care is experienced with four major categories elucidated, namely: links to tertiary health services, links to primary health services, communication between tertiary and primary health services, and lost in transition. Both positive and negative experiences were described; however, the importance of timely and informative discharge information, continuity of care, good communication between tertiary and primary health services, and strong therapeutic relationships were salient issues raised by participants. CONCLUSIONS: These findings highlight the importance of establishing strong therapeutic relationships between patients and tertiary and primary health professionals. Also important for survivorship is provision of discharge summaries or care plans at discharge for survivors and general practitioners as well as access to a range of allied health services. Alternative means for follow-up could be investigated for regional and rural survivors to facilitate convenient and cost-effective follow-up care. Finally, provision of responsive and flexible follow-up care to cater for the diverse range of needs and preferences of cancer survivors is required. A patient navigator available across the cancer continuum could go some way to addressing this.

Barriers to lung cancer care: health professionals' perspectives.

PURPOSE: Globally, lung cancer is the most common cancer and the leading cause of cancer death. Problematically, there is a wide variation in the management and survival for people with lung cancer and there is limited understanding of the reasons for these variations. To date, the views of health professionals across relevant disciplines who deliver such care are largely absent. The present study describes Australian health professionals' views about barriers to lung cancer care to help build a research and action agenda for improving lung cancer outcomes. METHODS: Qualitative semi-structured interviews were undertaken with a multidisciplinary group of 31 Australian health professionals working in lung cancer care for an average of 16 years (range 1-35 yrs.; SD = 10.2) seeing a mean of 116 patients annually. RESULTS: Three superordinate themes were identified: illness representations, cultural influences, and health system context. Illness representations included three themes: symptoms attributed as smoking-related but not cancer, health-related stigma, and therapeutic nihilism. Cultural influence themes included Indigenous health care preferences, language and communication, and sociodemographic factors. Health system context included lack of regional services and distance to treatment, poor care coordination, lack of effective screening methods, and health professional behaviours. CONCLUSIONS: Fractured and locally isolated approaches routinely confound responses to the social, cultural and health system complexities that surround a diagnosis of lung cancer and subsequent treatment. Improving outcomes for this disadvantaged patient group will require government, health agencies, and the community to take an aggressive, integrated approach balancing health policy, treatment priorities, and societal values.

Routine screening of Indigenous cancer patients' unmet support needs: a qualitative study of patient and clinician attitudes.

BACKGROUND: Indigenous Australians have poorer cancer outcomes in terms of incidence mortality and survival compared with non-Indigenous Australians. The factors contributing to this disparity are complex. Identifying and addressing the psychosocial factors and support needs of Indigenous cancer patients may help reduce this disparity. The Supportive Care Needs Assessment Tool for Indigenous People (SCNAT-IP) is a validated 26-item questionnaire developed to assess their unmet supportive care needs. This qualitative study reports on patient and clinician attitudes towards feasibility and acceptability of SCNAT-IP in routine care. METHODS: Forty-four in-depth semi-structured interviews were conducted with 10 clinical staff and 34 Indigenous cancer patients with heterogeneous tumours. Participants were recruited from four geographically diverse Australian cancer clinics. Transcripts were imported into qualitative analysis software (NVivo 10 Software), coded and thematic analysis performed. RESULTS: Indigenous patients (mean age 54.4 years) found the SCNAT-IP beneficial and easy to understand and they felt valued and heard. Clinical staff reported multiple benefits of using the SCNAT-IP. They particularly appreciated its comprehensive and systematic nature as well as the associated opportunities for early intervention. Some staff described improvements in team communication, while both staff and patients reported that new referrals to support services were directly triggered by completion of the SCNAT-IP. There were also inter-cultural benefits, with a positive and bi-directional exchange of information and cultural knowledge reported when using the SCNAT-IP. Although staff identified some potential barriers to using the SCNAT-IP, including the time required, the response format and comprehension difficulties amongst some participants with low English fluency, these were outweighed by the benefits. Some areas for scaled improvement were also identified by staff. CONCLUSIONS: Staff and patients found the SCNAT-IP to be an acceptable tool and supported universal screening for Indigenous cancer patients. The SCNAT-IP has the potential to help reduce the inequalities in cancer care experienced by Indigenous Australians by identifying and subsequently addressing their unmet support needs. Further research is needed to explore the validity of the SCNAT-IP for Indigenous people from other nations.

Health-related quality of life among Indigenous Australians diagnosed with cancer.

PURPOSE: Health-related quality of life (HRQoL) and associated factors were assessed among 155 Indigenous Australian adult cancer patients 6 months post-diagnosis. METHODS: The Assessment of Quality of Life-4D Questionnaire was used to assess HRQoL. Differences in the median utility score among subgroups of interest were examined using nonparametric tests. Factors associated with excellent HRQoL were assessed through logistic regression. RESULTS: Participants' mean age was 52 years (range 20-78), and the majority were female (60 %), unemployed (72 %), and recruited from outpatients clinics (64 %). Breast cancer (27 %) was the most common diagnosis. The median HRQoL score was 0.62; 14 % of participants reported excellent HRQoL (>0.90). After adjusting for age, admission status, and treatment, excellent HRQoL was more likely among participants of Torres Strait Islander origin [adjusted odds ratio (AOR) 3.68; 95 % CI 1.23-11.01], those living in regional areas (AOR 5.59; 95 % CI 1.42-22.06), and those whose main language spoken at home was not English (AOR 3.60; 95 % CI 1.08-11.99) and less likely among those reporting less contact with Indigenous people (AOR 0.23; 95 % CI 0.68-0.81). CONCLUSION: Assessing HRQoL is important to identifying and improving the length and quality of cancer survivorship, especially in groups that have significantly poorer cancer outcomes, such as Indigenous Australians. Acknowledging the study's observational nature, we found HRQoL was lower than reported for other Australians, and we identified some socio-demographic factors that were associated with excellent HRQoL. Such assessments are an important component of identifying and evaluating appropriate interventions to improve the health and well-being of Indigenous cancer patients.

Supportive care needs among Indigenous cancer patients in Queensland, Australia: less comorbidity is associated with greater practical and cultural unmet need.

Little is known about the supportive care needs (SCN) of Australian Indigenous cancer patients. This cross-sectional study investigated the association between comorbidity and SCN among newly diagnosed Indigenous cancer patients in Queensland. Comorbidity was ascertained from medical chart review using the Charlson Comorbidity Index (CCI) and SCN were measured using the Supportive Care Needs Assessment Tool for Indigenous Peoples (SCNAT-IP). Of 183 participants, 76 (42%) had no comorbidity (CCI = 0), 60 (33%) had had a CCI score of 1 and 47 (26%) had a CCI of two or more, with the most common condition being diabetes (30%). The most common moderate-high unmet need items varied between comorbidity groups, although all patients most frequently reported moderate-high unmet need in the Physical and Psychological and the Practical and Cultural needs domains. Patients with the greatest comorbidity (CCI ≥ 2) had significantly more reduced odds of practical and cultural needs than patients without comorbidity (OR 0.28, 95% CI 0.11-0.75). This appeared to be partially explained by time since diagnosis, age, whether they were receiving current treatment and residential remoteness. Patients' experience of chronic disease, hospitals and the healthcare system may better prepare them for the practical and cultural aspects of their cancer journey.

Health professional's perspectives of the barriers and enablers to cancer care for Indigenous Australians.

To investigate health professionals' perspectives about factors that impede or facilitate cancer care for Indigenous people. Semi-structured interviews with 22 health professionals involved in Indigenous cancer care. Data were interpreted using an inductive thematic analysis approach. Participants presented their perspectives on a number of barriers and enablers to Indigenous cancer care. Barriers were related to challenges with communication, the health system and coordination of care, issues around individual and community priorities and views of cancer treatment and health professional judgement. Enablers to cancer care were related to the importance of trust and rapport as well as health care system and support factors. The findings highlighted the need for recording of Indigenous status in medical records and a coordinated approach to the provision of evidence-based and culturally appropriate cancer care. This could go some way to improving Indigenous patient's engagement with tertiary cancer care services.

Population attributable fractions and joint effects of key risk factors for multiple sclerosis.

AIM: We examined the combined effect of having multiple key risk factors and the interactions between the key risk factors of multiple sclerosis (MS). METHODS: We performed an incident case-control study including cases with a first clinical diagnosis of central nervous system demyelination (FCD) and population-based controls. RESULTS: Compared to those without any risk factors, those with one, two, three, and four or five risk factors had increased odds of being an FCD case of 2.12 (95% confidence interval (CI), 1.11-4.03), 4.31 (95% CI, 2.24-8.31), 7.96 (95% CI, 3.84-16.49), and 21.24 (95% CI, 5.48-82.40), respectively. Only HLA-DR15 and history of infectious mononucleosis interacted significantly on the additive scale (Synergy index, 3.78; p = 0.03). The five key risk factors jointly accounted for 63.8% (95% CI, 43.9-91.4) of FCD onset. High anti-EBNA IgG was another important contributor. CONCLUSIONS: A high proportion of FCD onset can be explained by the currently known risk factors, with HLA-DR15, ever smoking and low cumulative sun exposure explaining most. We identified a significant interaction between HLA-DR15 and history of IM in predicting an FCD of CNS demyelination, which together with previous observations suggests that this is a true interaction.

Indigenous cancer patient and staff attitudes towards unmet needs screening using the SCNAT-IP.

INTRODUCTION: Indigenous Australians have a higher cancer incidence, worse mortality and are less likely to receive optimal cancer treatment compared with non-Indigenous Australians. Culturally appropriate supportive care helps ensure that Indigenous patients engage in and receive optimal care. However, many existing supportive care needs tools lack cultural relevance for Indigenous people, and their feasibility with Indigenous people has not been demonstrated. The Supportive Care Needs Assessment Tool for Indigenous People (SCNAT-IP) assesses the unmet supportive care needs of Indigenous cancer patients. PURPOSE: This descriptive study evaluates the clinical implementation of the SCNAT-IP in routine care. METHODS: Two large tertiary cancer treatment centres and two regional oncology clinics participated. Participants included 10 clinical staff and 36 adult Indigenous cancer patients (mean age 54 years). Patients and clinicians completed brief, purpose-designed questionnaires and interviews. RESULTS: Patients reported high ratings (means >8/10) for acceptability, helpfulness and timing items. The majority (≥80%) of staff agreed that the SCNAT-IP was useful to clinical practice, should be used in routine care and was acceptable to their patients. CONCLUSIONS: The study provides empirical support for the feasibility and acceptability of the SCNAT-IP in routine cancer care with Indigenous Australians. Routine screening with the SCNAT-IP has the potential to improve cancer care for Indigenous people with cancer.

Nasopharyngeal carriage and macrolide resistance in Indigenous children with bronchiectasis randomized to long-term azithromycin or placebo.

Although long-term azithromycin decreases exacerbation frequency in bronchiectasis, increased macrolide resistance is concerning. We investigated macrolide resistance determinants in a secondary analysis of a multicenter randomized controlled trial. Indigenous Australian children living in remote regions and urban New Zealand Maori and Pacific Islander children with bronchiectasis were randomized to weekly azithromycin (30 mg/kg) or placebo for up to 24 months and followed post-intervention for up to 12 months. Nurses administered and recorded medications given and collected nasopharyngeal swabs 3-6 monthly for culture and antimicrobial susceptibility testing. Nasopharyngeal carriage of Haemophilus influenzae and Moraxella catarrhalis was significantly lower in azithromycin compared to placebo groups, while macrolide-resistant Streptococcus pneumoniae and Staphylococcus aureus carriage was significantly higher. Australian children, compared to New Zealand children, had higher carriage overall, significantly higher carriage of macrolide-resistant bacteria at baseline (16/38 versus 2/40 children) and during the intervention (69/152 versus 22/239 swabs), and lower mean adherence to study medication (63 % versus 92 %). Adherence ≥70 % (versus <70 %) in the Australian azithromycin group was associated with lower carriage of any pathogen [odds ratio (OR) 0.19, 95 % confidence interval (CI) 0.07-0.53] and fewer macrolide-resistant pathogens (OR 0.34, 95 % CI 0.14-0.81). Post-intervention (median 6 months), macrolide resistance in S. pneumoniae declined significantly in the azithromycin group, from 79 % (11/14) to 7 % (1/14) of positive swabs, but S. aureus strains remained 100 % macrolide resistant. Azithromycin treatment, the Australian remote setting, and adherence <70 % were significant independent determinants of macrolide resistance in children with bronchiectasis. Adherence to treatment may limit macrolide resistance by suppressing carriage.

Occupational exposure and risk of central nervous system demyelination.

Inconsistent evidence exists regarding the association between work-related factors and risk of multiple sclerosis (MS). We examined the association between occupational exposures and risk of a first clinical diagnosis of central nervous system demyelination (FCD), which is strongly associated with progression to MS, in a matched case-control study of 276 FCD cases and 538 controls conducted in Australia (2003-2006). Using a personal residence and work calendar, information on occupational history and exposure to chemicals and animals was collected through face-to-face interviews. Few case-control differences were noted. Fewer cases had worked as professionals (≥6 years) than controls (adjusted odds ratio (AOR) = 0.60, 95% confidence interval (CI): 0.37, 0.96). After further adjustment for number of children, cases were more likely to have ever been exposed to livestock than controls (AOR = 1.54, 95% CI: 1.03, 2.29). Among women, there was an increase in FCD risk associated with 10 or more years of exposure to livestock (AOR = 2.78, 95% CI: 1.22, 6.33) or 6 or more years of farming (AOR = 2.00, 95% CI: 1.23, 3.25; also adjusted for number of children). Similar findings were not evident among men. Thus, farming and exposure to livestock may be important factors in the development of FCD among women, with this finding further revealed after the confounding effect of parity or number of children is considered.

Population-based survival estimates for childhood cancer in Australia during the period 1997-2006.

BACKGROUND: This study provides the latest available relative survival data for Australian childhood cancer patients. METHODS: Data from the population-based Australian Paediatric Cancer Registry were used to describe relative survival outcomes using the period method for 11,903 children diagnosed with cancer between 1983 and 2006 and prevalent at any time between 1997 and 2006. RESULTS: The overall relative survival was 90.4% after 1 year, 79.5% after 5 years and 74.7% after 20 years. Where information onstage at diagnosis was available (lymphomas, neuroblastoma, renal tumours and rhabdomyosarcomas), survival was significantly poorer for more-advanced stage. Survival was lower among infants compared with other children for those diagnosed with leukaemia, tumours of the central nervous system and renal tumours but higher for neuroblastoma. Recent improvements in overall childhood cancer survival over time are mainly because of improvements among leukaemia patients. CONCLUSION: The high and improving survival prognosis for children diagnosed with cancer in Australia is consistent with various international estimates. However, a 5-year survival estimate of 79% still means that many children who are diagnosed with cancer will die within 5 years, whereas others have long-term health morbidities and complications associated with their treatments. It is hoped that continued developments in treatment protocols will result in further improvements in survival.

Trends in incidence of childhood cancer in Australia, 1983-2006.

BACKGROUND: There are few population-based childhood cancer registries in the world containing stage and treatment data. METHODS: Data from the population-based Australian Paediatric Cancer Registry were used to calculate incidence rates during the most recent 10-year period (1997-2006) and trends in incidence between 1983 and 2006 for the 12 major diagnostic groups of the International Classification of Childhood Cancer. RESULTS: In the period 1997-2006, there were 6184 childhood cancer (at 0-14 years) cases in Australia (157 cases per million children). The commonest cancers were leukaemia (34%), that of the central nervous system (23%) and lymphomas (10%), with incidence the highest at 0-4 years (223 cases per million). Trend analyses showed that incidence among boys for all cancers combined increased by 1.6% per year from 1983 to 1994 but have remained stable since. Incidence rates for girls consistently increased by 0.9% per year. Since 1983, there have been significant increases among boys and girls for leukaemia, and hepatic and germ-cell tumours, whereas for boys, incidence of neuroblastomas and malignant epithelial tumours has recently decreased. For all cancers and for both sexes combined, there was a consistent increase (+0.7% per year, 1983-2006) at age 0-4 years, a slight non-significant increase at 5-9 years, and at 10-14 years, an initial increase (2.7% per year, 1983-1996) followed by a slight non-significant decrease. CONCLUSION: Although there is some evidence of a recent plateau in cancer incidence rates in Australia for boys and older children, interpretation is difficult without a better understanding of what underlies the changes reported.

Association of diabetes with survival among cohorts of Indigenous and non-Indigenous Australians with cancer.

BACKGROUND: The association between diabetes and cancer incidence has been well documented, but relatively little research has been undertaken on the potential influence of diabetes on cancer survival and the research that is available has produced inconsistent results. Because Indigenous Australians have a high prevalence of diabetes, we assessed survival, stratified by diabetes, among Indigenous Australian cancer patients. We also assessed survival, stratified by diabetes, amongst a cohort of non-Indigenous Australian cancer patients. METHODS: All-cause survival and cancer-specific survival in diabetic versus non-diabetic cancer patients were assessed in Indigenous and non-Indigenous cohorts separately, using proportional hazards models. FINDINGS: Indigenous cancer patients with diabetes (n = 140) had an overall survival disadvantage compared to Indigenous cancer patients without diabetes (n = 675) with all-cause Hazard Ratio (HR) = 1.4 (95% CI 1.1-1.8) adjusted for age, sex, and cancer site. After further adjustment to take into account the greater number of non-cancer deaths and co-morbidities in Indigenous cancer patients with diabetes, and their later stage at cancer diagnosis with less cancer treatment, there was no residual difference in cancer-specific survival compared to Indigenous cancer patients without diabetes (cancer-specific HR = 1.0, 95% CI 0.8, 1.3). Fewer non-Indigenous cancer patients had diabetes (n = 52) and they showed no differences in survival compared to their counterparts without diabetes. INTERPRETATION: The poorer survival of Indigenous Australian cancer patients with diabetes was due to more non-cancer deaths, later stage at cancer diagnosis, less cancer treatment, and more co-morbidities than Indigenous Australian cancer patients without diabetes. In contrast, diabetes did not appear to affect survival in non-Indigenous Australians with cancer, either because there were too few to detect a moderate deleterious effect or because there was no association. Understanding the relation between diabetes and cancer treatment and survival is important because both diabetes and cancer are relatively common diseases, increasingly likely to co-exist.

'Free' surfactant in gastric aspirates and bronchoalveolar lavage in children with and without reflux oesophagitis.

AIM: Dipalmitoylphosphatidycholine (DPPC) is the characteristic and main constituent of surfactant. Adsorption of surfactant to epithelial surfaces may be important in the masking of receptors. The aims of the study were to (i) compare the quantity of free DPPC in the airways and gastric aspirates of children with gastroesophageal reflux disease (GORD) to those without and (ii) describe the association between free DPPC levels with airway cellular profile and capsaicin cough sensitivity. METHODS: Children aged <14 years were defined as 'coughers' if a history of cough in association with their GORD symptoms was elicited before gastric aspirates and nonbronchoscopic bronchoalveolar lavage (BAL) were obtained during elective flexible upper gastrointestinal endoscopy. GORD was defined as histological presence of reflux oesophagitis. Spirometry and capsaicin cough-sensitivity test was carried out in children aged >6 years before the endoscopy. RESULTS: Median age of the 68 children was 9 years (interquartile range (IQR) 7.2). Median DPPC level in BAL of children with cough (72.7 microg/mL) was similar to noncoughers (88.5). There was also no significant difference in DPPC levels in both BAL and gastric aspirates of children classified according to presence of GORD. There was no correlation between DPPC levels and cellular counts or capsaicin cough-sensitivity outcome measures. CONCLUSION: We conclude that free DPPC levels in the airways and gastric aspirate is not influenced by presence of cough or GORD defined by histological presence of reflux oesophagitis. Whether quantification of adsorbed surfactant differs in these groups remain unknown. Free DPPC is unlikely to have a role in masking of airway receptors.

Electronic telephone directory listings: preferred sampling frame for a population-based study of childhood cancer in Australia.

PURPOSE: We report our telephone-based system for selecting community control series appropriate for a complete Australia-wide series of Ewing's sarcoma cases. METHODS: We used electronic directory random sampling to select age-matched controls. The sampling has all listed telephone numbers on an up-dated CD-Rom. RESULTS: 95% of 2245 telephone numbers selected were successfully contacted. The mean number of attempts needed was 1.94, 58% answering at the first attempt. On average, we needed 4.5 contacts per control selected. Calls were more likely to be successful (reach a respondent) when made in the evening (except Saturdays). The overall response rate among contacted telephone numbers was 92.8%. Participation rates among female and male respondents were practically the same. The exclusion of unlisted numbers (13.5% of connected households) and unconnected households (3.7%) led to potential selection bias. However, restricting the case series to listed cases only, plus having external information on the direction of potential bias allow meaningful interpretation of our data. CONCLUSION: Sampling from an electronic directory is convenient, economical and simple, and gives a very good yield of eligible subjects compared to other methods.

Do forecasts of UV indexes influence people's outdoor behaviour?

OBJECTIVE: To investigate Australian adults' awareness of the ultraviolet (UV) indexes forecast in the media, and whether these UV forecasts influence their behaviour in the sun. METHODS: A self-administered questionnaire was used on two occasions in 1997 to ask about knowledge of UV indexes shown in the media and about possible influence on outdoor behaviour. SETTING AND PARTICIPANTS: Participants were 977 residents (423 men; 554 women) of Nambour originally randomly selected in 1986 from the electoral roll, who have been followed up subsequently. RESULTS: The majority of people--92% of men and 86% of women--reported having seen or heard the UV indexes forecast during summer. Of these, significantly fewer men (107; 28%) than women (209; 46%) reported that their outdoor behaviour was influenced by knowledge of the forecast (p = 0.001). Neither age nor skin type, nor history of sunburns or skin cancer, affected knowledge of UV forecasts or their influence on behaviour. CONCLUSIONS AND IMPLICATIONS: Although most people are aware of the forecasts of UV indexes in the media, the majority do not take them into account in their outdoor behaviour. Compared with women, men were more aware of, but less influenced by, forecasts of UV indexes. Better communication of the implications of the UV indexes is needed, particularly to men, if they are to adapt their outdoor behaviour to improve their sun protection.
