Purpose: To explore whether there was a difference in objectively measured physical activity and study participation between people who received their preferred study group allocation (matched) and those who did not receive their preferred study group (mismatched). Design: Secondary data from the NewCOACH randomized controlled trial. Setting: Insufficiently active patients in the primary care settings in Sydney and Newcastle, Australia. Participants: One hundred seventy-two adults aged 20 to 81 years. Intervention: Participants indicated their intervention preference at baseline for (1) five face-to-face visits with an exercise specialist, (2) one face-to-face visit and 4 telephone follow-ups with an exercise specialist, (3) written material, or (4) slight-to-no preference. Participants were then allocated to an intervention group and categorized as either ¿matched¿ or ¿mismatched¿ based on their indications. Participants who reported a slight-to-no preference was categorized as ¿matched.¿ Measures: Daily step count as measured by pedometers and study participation. Analysis: Mean differences between groups in daily step count at 3 and 12 months (multiple linear regression models) and study participation at baseline, 3 months, and 12 months (¿2 tests). Results: Preference for an intervention group prior to randomization did not significantly (all P¿s >.05 using 95% confidence interval) impact step counts (differences of <600 steps/day between groups) or study participation. Conclusion: Future research should continue to address whether the strength of preferences influence study outcome and participation and whether the study preferences change over time.

Aims and objectives: To explore patient and healthcare provider (HCP) perspectives about patients¿ barriers to the performance of diabetic self-care behaviours in Ghana. Background: Sub-Saharan African urban populations are increasingly affected by type 2 diabetes due to nutrition transition, sedentary lifestyles and ageing. Diabetic self-care is critical to improving clinical outcomes. However, little is known about barriers to diabetic self-care (diet, exercise, medication taking, self-monitoring of blood glucose and foot care) in sub-Saharan Africa. Design: Qualitative study that followed the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines. Methods: Semi-structured interviews were conducted among 23 people living with type 2 diabetes and 14 HCPs recruited from the diabetes clinics of three hospitals in Tamale, Ghana. Interviews were audiotaped and transcribed verbatim. The constant comparative method of data analysis was used and identified themes classified according to constructs of the theory of planned behaviour (TPB): attitudes/behavioural beliefs, subjective norms and perceived behavioural control. Results: Barriers relating to attitudes included misconceptions that diabetes was caused by spiritual forces or curses, use of herbal medicines, intentional nonadherence, difficulty changing old habits, and feeling or lacking motivation to exercise. Barriers relating to subjective norms were inadequate family support, social stigma (usually by spouses and other members of the community) and cultural beliefs. Perceived behavioural control barriers were poor income levels, lack of glucometers, busy work schedules, long distance to the hospital and inadequate access to variety of foods due to erratic supply of foods or seasonality. Conclusions: Both patients and HCPs discussed similar barriers and those relating to attitude and behavioural control were commonly discussed. Relevance to Clinical Practice: Interventions to improve adherence to diabetic self-care should focus on helping persons with diabetes develop favourable attitudes and how to overcome behavioural control barriers. Such interventions should have both individualised and community-wide approaches.

Aims: To determine diabetes patient's adherence to five self-care behaviours (diet, exercise; medication, self-monitoring of blood glucose [SMBG] and foot care) in low- and middle-income countries. Design: Systematic review. Data sources: We searched MEDLINE, CINAHL, PUBMED, SCOPUS, PsycINFO, EMBASE, Cochrane library and EMCARE for the period January 1990 ¿ June 2017. Review Methods: Title, abstract and full text screening were done according to eligibility criteria. A narrative synthesis of the literature was conducted. Results: A total of 7,109 studies were identified of which 27 met the review eligibility criteria and were included. All the studies used self-report of adherence to diabetes self-care. Studies reported adherence rates in two major forms: (a) mean number of days participants performed a recommended dietary behaviour/activity during the past week; and (b) proportions of participants adhering to a recommended self-care behaviour. Mean number of days per week participants adhered to a self-care behaviour ranged from 2.34.6¿days per week for diet, 5.5¿6.8¿days per week for medication, 1.8¿5.7¿days per week for exercise, 0.2¿2.2¿days per week for SMBG and 2.2¿4.3¿days per week for foot care. Adherence rates ranged from 29.9%¿91.7% for diet, 26.0%¿97.0% for medication taking, 26.7%¿69.0% for exercise, 13.0%¿79.9% for self-monitoring of blood glucose and 17.0%¿77.4% for foot care. Conclusion: Although most diabetes patients do not adhere to recommended self-care behaviours, adherence rates vary widely and were found to be high in some instances. Impact: Health services in low- and middle-income countries should monitor adherence to diabetes self-care behaviours rather than assume adherence and resources should be invested in improving adherence to the self-care behaviours. Large-scale accurate monitoring of adherence to diabetes self-care behaviour is needed and consideration should be given to choice of measurement tool for such exercise.

Aims: We evaluated the content validity, factorial structure, internal consistency, construct validity, and floor and ceiling effects of the SDSCA among Ghanaian persons with type 2 diabetes. Methods: The summary of diabetes self-care activities measure (SDSCA) was administered to 187 adults living with type 2 diabetes from three diabetes clinics. Results: A confirmatory factor analysis maintained the four factor structure of the SDSCA. However, two items, 3 (fruit and vegetable servings) and 4 (red meat or full-fat dairy products) had factor loadings of 0.26 and 0.16 respectively. The model also had a statistical power of 0.72 (below acceptable criteria). Modification of the model by removing item 4 resulted in an improved revised model with a power of 0.82. Construct validity was found for the exercise and diet subscales of the SDSCA but not for the self-monitoring of blood glucose and foot care subscales. The internal consistency of the SDSCA measure was 0.68, below acceptable criteria for internal consistency. No floor effects were present but the exercise subscale had ceiling effects. Conclusion: The SDSCA measure had content validity, maintained its multidimensionality and met the criteria for floor effects but not for construct validity, internal consistency and ceiling effects. The SDSCA measure may require improvements to evaluate self-care behaviours of adult type 2 diabetes patients in Ghana and probably in other sub-Saharan countries.

Opportunities for evaluating experiential learning activities in tertiary public health education are growing. It has previously been shown that utilizing the ¿This is Public Health¿ (TIPH) sticker campaign as an experiential photo essay task led to increased understanding of public health. Emerging mobile technologies such as geocaching, which provide an opportunity to increase the experiential component of the TIPH photo essay task, have not been evaluated. This study aimed to determine whether adding geocaching to the TIPH photo essay task increased the efficacy of learning about public health, when compared with the TIPH photo essay task alone. A two-arm nonrandomized trial was conducted with 785 allied health and preprofessional teaching students studying first-year public health courses. Students were allocated to either the TIPH photo essay task (n = 210) or the TIPH photo task plus geocaching (n = 92) according to the course they were enrolled into. The primary outcome was the quality of the definition of public health provided by students, which was assessed using the Definition of Public Health Rating Scale. Data were analyzed using a linear mixed model. Of 302 (39%) students who consented to participate, 212 (70%) provided baseline and follow-up data. After adjusting for baseline demographic differences, the geocaching group had improved knowledge of public health at follow-up according to the Definition of Public Health Rating Scale (increasing 0.29 units more than the traditional group; p =.03). As this increase in knowledge score is unlikely to be of practical significance, the additional burden of implementing geocaching may not be justified.

Statement of the problem: Self-care support provided by healthcare providers (HCPs) is critical to diabetes self-care. However, a number of barriers prevent HCPs from providing self-care support to people with diabetes. We explored attitudes towards, barriers and facilitators of the provision of diabetes self-care support among Ghanaian HCPs. Methods: Fourteen semi-structured interviews were conducted among HCPs recruited from three diabetes clinics in Tamale, Ghana. All interviews were digitally recorded and transcribed verbatim. Transcripts were coded and analysed thematically. Results: HCPs reported a sense of responsibility and urgency to provide self-care education to diabetes patients; while believing it was the patients¿ responsibility to self-care for their diabetes condition. Accordingly, HCPs perceived their role to be limited to information sharing rather than behaviour change interventions. Facilitators to the provision of self-care support included patients¿ motivation, and team work among healthcare professionals. Barriers that hindered self-care support included language barriers and poor inter-professional collaboration. Furthermore, HCPs discussed that they felt inadequately trained to provide self-care support. Healthcare-system-related barriers were inadequate office space, lack of professional development programmes, high patient numbers, inadequate staff numbers, inadequate health insurance and a lack of sufficient supplies and equipment in the hospital. Conclusion: HCPs attitudes were generally favourable towards supporting self-care, albeit with a focus on information provision rather than behaviour change. Training in effective strategies for providing self-care support are needed, and better use of the resources that are available.

Objective: Interventions to promote physical activity for sedentary patients seen in general practice may be a way to reduce the burden of chronic disease. Coaching by an exercise physiologist is publicly funded in Australia, but cost effectiveness has not been documented. Methods: In a three-arm randomised controlled trial, face-to-face coaching and telephone coaching over 12 weeks were compared with a control group using the outcome of step count for one week at baseline, three months and twelve months. Program costs and time-based costs were considered. Quality of life was measured as a secondary outcome. Results: At 12 months, the intervention groups were more active than controls by 1,002 steps per day (95%CI 244, 1,759). This was achieved at a cost of AUD$245 per person. There was no change in reported quality of life or utility values. Conclusion: Coaching achieved a modest increase in activity equivalent to 10 minutes walking per day, at a cost of AUD$245 per person. Face-to-face and telephone counselling were both effective. Implication for public health: Persistence of increases nine months after the end of coaching suggests it creates long-term change and is a good value health intervention.

Background: Most trials of electronic alcohol screening and brief intervention (e-SBI) have been conducted in young people. The aim of this study was to evaluate the effect of e-SBI in adults with hazardous or harmful drinking. Methods: This individually randomized, parallel, two-group, double-blind controlled trial was conducted in the outpatient department of a large public hospital in Australia. Consenting adults who scored 5¿9 on the AUDIT-C (837/3225; 26%) were randomized in a 1:1 ratio by computer to screening alone (442/837; 53%) or to 10 min of assessment and personalized feedback on their alcohol consumption (comparisons with medical guidelines and age and sex-specific norms), peak blood alcohol concentration, expenditure on alcohol, and risk of alcohol dependence (395/837; 47%). The two primary outcomes, assessed six months after randomization, were the number of standard drinks (10 g ethanol) consumed by participants in the last seven days and their AUDIT score. Results: 693/837 (83%) and 635/837 (76%) participants were followed-up at 6 and 12 months, respectively. There was no statistically significant difference between the groups in the median number of standard drinks consumed in the last seven days (intervention: 12; control: 10.5; rate ratio, 1.12 [95% confidence interval, 0.96¿1.31]; P =.17) or in their median AUDIT score (intervention: 7; control: 7; mean difference, 0.28 [-0.42 to 0.98]; P =.44). Conclusion: These results do not support the implementation of an e-SBI program comprising personalized feedback and normative feedback for adults with hazardous or harmful drinking in the hospital outpatient setting.

The Institute for Urban Indigenous Health (IUIH) aimed to improve access to cataract surgery in urban South East Queensland (SEQ) for Indigenous Australians, without compromising clinical visual outcomes. The Penchansky and Levesque concept of access as the 'fit' between the patient's needs and the ability of the system to meet those needs was used to inform the redesign of the mainstream cataract surgical pathway. The IUIH staff and community stakeholders mapped the traditional external cataract surgical pathway and then innovatively redesigned it to reduce the number of patients being removed by the system at key transition points. The integration of eye health within the primary health care (PHC) clinic has improved the continuity and coordination of care along the surgical pathway, and ensured the sustainability of collaborative partnerships with key external organisations. Audit data demonstrated a significant increase in utilisation of cataract surgical services after the process redesign. Previous studies have found that PHC models involving integration, coordination and continuity of care enhance patient health outcomes however, the IUIH surgical model extends this to tertiary care. There is scope to apply this model to other surgical pathways and communities who experience access inequity.

Introduction Primary care physicians are well placed to offer physical activity counseling, but insufficient time is a barrier. Referral to an exercise specialist is an alternative. In Australia, exercise specialists are publicly funded to provide face-to-face counseling to patients who have an existing chronic illness. This trial aimed to (1) determine the efficacy of primary care physicians¿ referral of insufficiently active patients for counseling to increase physical activity, compared with usual care, and (2) compare the efficacy of face-to-face counseling with counseling predominantly via telephone. Study design Three-arm pragmatic RCT. Setting/participants Two hundred three insufficiently active (<7,000 steps/day) primary care practice patients (mean age 57 years; 70% female) recruited in New South Wales, Australia, in 2011¿2014. Intervention (1) Five face-to-face counseling sessions by an exercise specialist, (2) one face-to-face counseling session followed by four telephone calls by an exercise specialist, or (3) a generic mailed physical activity brochure (usual care). The counseling sessions operationalized social cognitive theory via a behavior change counseling framework. Main outcome measures Change in average daily step counts between baseline and 12 months. Data were analyzed in 2016. Results Forty (20%) participants formally withdrew; completion rates at 3 and 6 months were 64% and 58%, respectively. Intervention attendance was high (75% received five sessions). The estimated mean difference between usual care and the combined intervention groups at 12 months was 1,002 steps/day (95% CI=244, 1,759, p=0.01). When comparing face-to-face with predominantly telephone counseling, the telephone group had a non-significant higher mean daily step count (by 619 steps) at 12 months. Conclusions Provision of expert physical activity counseling to insufficiently active primary care patients resulted in a significant increase in physical activity (approximately 70 minutes of walking per week) at 12 months. Face-to-face only and counseling conducted predominantly via telephone were both effective. This trial provides evidence to expand public funding for expert physical activity counseling and for delivery via telephone in addition to face-to-face consultations.

Objective: There have been no trials in healthcare settings of genetic susceptibility feedback in relation to alcohol consumption. The purpose of this study was to determine the feasibility and acceptability of conducting a full-scale randomised trial estimating the effect of personalised genetic susceptibility feedback on alcohol consumption in hospital outpatients with risky drinking. Methods: Outpatients =18 years of age who reported drinking more than 14 standard drinks in the past week or in a typical week were asked to provide a saliva sample for genetic testing. Genetic susceptibility feedback was posted to participants 6 months after recruitment. The co-primary outcomes were the proportion of participants who (i) provided a saliva sample that could be genotyped, and (ii) spoke with a genetic counsellor. Secondary outcomes included changes in patients' weekly alcohol consumption; scores on scales measuring readiness to change, importance of changing and confidence in ability to change drinking habits; knowledge about which cancers are alcohol-attributable; and acceptability of the saliva collection procedure and the genetic-feedback intervention. McNemar's test and paired t-tests were used to test for differences between baseline and follow-up in proportions and means, respectively. Results: Of 100 participants who provided a saliva sample, 93 had adequate DNA for at least one genotyping assay. Three participants spoke to a genetic counsellor. Patients' readiness to change their drinking, their views on the importance of changing and their stated confidence in their ability to change increased between baseline and follow-up. There was no increase in patients' knowledge about alcohol-attributable cancers nor any reduction in how much alcohol they drank 4 months after receiving the feedback. Most participants (80%) were somewhat comfortable or very comfortable with the process used to collect saliva, 84% understood the genetic feedback, 54% found it useful, 10% had sought support to reduce their drinking after receiving the feedback, and 37% reported that the feedback would affect how much they drink in the future. Conclusion: Results of this study suggest it would be feasible to conduct a methodologically robust trial estimating the effect of genetic susceptibility feedback on alcohol consumption in hospital outpatients with risky drinking.

Background: Growing evidence points to the benefits of addressing multiple health behaviors rather than single behaviors. Purpose: This review evaluates the relative effectiveness of simultaneous and sequentially delivered multiple health behavior change (MHBC) interventions. Secondary aims were to identify: a) the most effective spacing of sequentially delivered components; b) differences in efficacy of MHBC interventions for adoption/cessation behaviors and lifestyle/addictive behaviors, and c) differences in trial retention between simultaneously and sequentially delivered interventions. Methods: MHBC intervention trials published up to October 2015 were identified through a systematic search. Eligible trials were randomised controlled trials that directly compared simultaneous and sequential delivery of a MHBC intervention. A narrative synthesis was undertaken. Results: Six trials met the inclusion criteria and across these trials the behaviors targeted were smoking, diet, physical activity, and alcohol consumption. Three trials reported a difference in intervention effect between a sequential and simultaneous approach in at least one behavioral outcome. Of these, two trials favoured a sequential approach on smoking. One trial favoured a simultaneous approach on fat intake. There was no difference in retention between sequential and simultaneous approaches. Conclusions: There is limited evidence regarding the relative effectiveness of sequential and simultaneous approaches. Given only three of the six trials observed a difference in intervention effectiveness for one health behavior outcome, and the relatively consistent finding that the sequential and simultaneous approaches were more effective than a usual/minimal care control condition, it appears that both approaches should be considered equally efficacious. PROSPERO registration number: CRD42015027876.

Objectives: Telephone follow-up is not currently recommended as a strategy to improve retention in randomized trials. The aims of this study were to estimate the effect of telephone follow-up on retention, identify participant characteristics predictive of questionnaire completion during or after telephone follow-up, and estimate the effect of including participants who provided follow-up data during or after telephone follow-up on balance between randomly allocated groups in a trial estimating the effect of electronic alcohol screening and brief intervention on alcohol consumption in hospital outpatients with hazardous or harmful drinking. Method: Trial participants were followed up 6. months after randomization (June-December 2013) using e-mails containing a hyperlink to a web-based questionnaire when possible and by post otherwise. Telephone follow-up was attempted after two written reminders and participants were invited to complete the questionnaire by telephone when contact was made. Results: Retention before telephone follow-up was 62.1% (520/837) and 82.8% (693/837) afterward: an increase of 20.7% (173/837). Therefore, 55% (95% CI 49%-60%) of the 317 participants who had not responded after two written reminders responded during or after the follow-up telephone call. Age. <. 55. years, a higher AUDIT-C score and provision of a mobile/cell phone number were predictive of questionnaire completion during or after telephone follow-up. Balance between randomly allocated groups was present before and after inclusion of participants who completed the questionnaire during or after telephone follow-up. Conclusion: Telephone follow-up improved retention in this randomized trial without affecting balance between the randomly allocated groups.

This study examined factors associated with higher sitting time in general, chronic disease, and psychologically-distressed, adult populations (aged =45 years). A series of logistic regression models examined potential socio-demographic and health factors associated with higher sitting (=6hrs/day) in adults from the 45 and Up Study (n = 227,187), including four separate subsamples for analysis comprising those who had ever had heart disease (n = 26,599), cancer (n = 36,381), diabetes (n = 19,550) or psychological distress (n = 48,334). Odds of higher sitting were significantly (p<.01) associated with a number of factors across these groups, with an effect size of ORs=1.5 observed for the high-income =$70,000AUD, employed full-time and severe physical limitations demographics. Identification of key factors associated with higher sitting time in this population-based sample will assist development of broad-based, public health and targeted strategies to reduce sitting-time. In particular, those categorized as being high-income earners, full-time workers, as well as those with severe physical limitations need to be of priority, as higher sitting appears to be substantial across these groups.

Background: Few studies have examined the prevalence of unhealthy alcohol use in the hospital outpatient setting. Our aim was to estimate the prevalence of unhealthy alcohol use among patients attending a broad range of outpatient clinics at a large public hospital in Australia. Methods: Adult hospital outpatients were invited to complete the Alcohol Use Disorders Identification Test Consumption questions (AUDIT-C) using an iPad as part of a randomised trial testing the efficacy of alcohol electronic screening and brief intervention. Unhealthy alcohol use was defined as an AUDIT-C score =5 among men and =4 among women. Results: Sixty percent (3616/6070) of invited hospital outpatients consented, of whom 89% (3206/3616) provided information on their alcohol consumption (either reported they had not consumed any alcohol in the last 12 months or completed the AUDIT-C). The prevalence of unhealthy alcohol use was 34.7% (95% confidence interval [CI]: 33.0-36.3%). The prevalence among men aged 18-24 years, 25-39 years, 40-59 years and 60 years and older, was 74.4% (95% CI: 68.4-80.4%), 54.3% (95% CI: 48.7-59.8%), 44.1% (95% CI: 39.9-48.3%), and 27.0% (95% CI: 23.6-30.4%), respectively (43.1% overall; 95% CI: 40.8-45.5%). The prevalence among women aged 18-24 years, 25-39 years, 40-59 years, and 60 years and older, was 48.6% (95% CI: 39.2-58.1%), 36.9% (95% CI: 31.2-42.6%), 25.2% (95% CI: 21.5-29.0%) and 14.5% (95% CI: 11.7-17.3%), respectively (24.9% overall; 95% CI: 22.7-27.1%). Conclusion: A large number of hospital outpatients who are not currently seeking treatment for their drinking could benefit from effective intervention in this setting.
