The feasibility, acceptability and potential efficacy of a parental text message and social media program on children's vegetable consumption and movement behaviours: A pilot randomised controlled trial.

ISSUE ADDRESSED: Australian children fall short of meeting the dietary, physical activity and sedentary behaviour guidelines. This study aimed to test the feasibility, acceptability and potential efficacy of a parental text message and social media program on, primarily, their school-aged children's vegetable consumption and movement behaviours, and, secondarily, their own. METHODS: Between August and November 2022, we conducted a two-armed randomised controlled trial with 242 parents/caregivers of primary school-aged children in New South Wales. The 'Adventure & Veg' intervention ran for 8 weeks, promoting vegetable eating behaviours, local outdoor physical activity opportunities and ideas for reducing screen time. Feasibility and acceptability were assessed via recruitment and retention data, intervention metrics and self-reported participant data. Vegetable intake and movement behaviour data were collected via online-surveys and effect sizes were examined. RESULTS: Most participants reported that they enjoyed receiving the text messages (88%) and the delivery frequency was acceptable (94%). Limitations to Facebook as a delivery platform were reported. The majority of participants used the text messages to influence the vegetable eating (65%) and movement (77%) behaviours of their child. Significant effects were observed among intervention child participants compared with control for mean daily vegetable consumption (0.45 serves, CI: .19; .71, p = .001, d = .5); weekly vegetable variety (1.85, CI: .25; 3.45, p < .001, d = .6); and weekly physical activity variety (.64 CI: .09; 1.19, p = .022, d = .3). Parents in the intervention group increased their daily vegetable intake by .44 serves (CI: .11; .78, p = .01, d = .4). CONCLUSIONS: A parental text message and social media program has potential to support children's vegetable intake and movement behaviours. Further research is required to explore different online delivery methods to promote local outdoor activity options. SO WHAT?: The Adventure & Veg program holds promise as a stand-alone health promotion intervention or as a useful adjunct to current family or school-based healthy lifestyle programs.

Children's physical activity and sedentary behaviour in before school care: An observational study.

OBJECTIVE: In Australia, less than one quarter of children aged 5-12 years meet national physical activity (PA) guidelines. Before school care operates as part of Out of School Hours Care (OSHC) services and provide opportunities for children to meet their daily PA recommendations. The aim of this study was to explore factors associated with children meeting 15 min of moderate-to-vigorous-intensity physical activity (MVPA) while attending before school care. METHODS: A cross-sectional study was conducted in 25 services in New South Wales, Australia. Each service was visited twice between March and June 2021. Staff behaviours and PA type and context were captured using staff interviews and the validated System for Observing Staff Promotion of Physical Activity and Nutrition (SOSPAN) time sampling tool. Child PA data were collected using Actigraph accelerometers and associations between program practices and child MVPA analysed. RESULTS: PA data were analysed for 654 children who spent an average of 39.2% (±17.6) of their time sedentary; 45.4% (±11.4) in light PA; and 14.9% (±11.7) in MVPA. Only 17% of children (n = 112) reached ≥15 min MVPA, with boys more likely to achieve this. Children were more likely to meet this recommendation in services where staff promoted and engaged in PA; PA equipment was available; children were observed in child-led free play; and a written PA policy existed. CONCLUSIONS: Before school care should be supported to improve physical activity promotion practices by offering staff professional development and guidance on PA policy development and implementation practices.

Healthy kids vids: Development and acceptability of narrative healthy lifestyle videos and text messages for parents of young children from socioeconomically disadvantaged populations.

ISSUE ADDRESSED: Dietary intake and physical activity behaviours of many Australian children are not meeting recommendations, particularly for those living in socioeconomically disadvantaged circumstances. This study aimed to design and assess the feasibility and acceptability of a suite of narrative videos and text messages focused on healthy eating and physical activity behaviours appropriate for parents of young children from socioeconomically disadvantaged backgrounds. METHODS: Parents of 1-5-year-old children (n = 6) were recruited to develop a suite of 12 narrative videos on healthy eating and physical activity behaviours, underpinned by theory. Twelve complementary text messages were subsequently developed. A different group of parents (n = 16) recruited from socioeconomically disadvantaged areas reviewed the videos and text messages over 6 weeks and provided feedback via surveys and qualitative interviews (n = 13). RESULTS: There was a high level of engagement with and acceptability of the videos and text message content. Participants found the videos easy to access and they liked the narrative style. Screen time videos and text messages relating to screen time, play and physical activity, role modelling and fussy eating were most useful. CONCLUSIONS: Narrative style healthy eating, physical activity and screen time videos and complementary text messages were highly acceptable to the sample of parents of 1-5-year-old children from socioeconomically disadvantaged areas recruited from the Illawarra Shoalhaven region of NSW, Australia. SO WHAT?: Short narrative style videos and text messages are an easy to process and acceptable method of delivering healthy lifestyle promotion content to parents.

Economic evaluation of a mobile phone text-message intervention for Australian adults with type 2 diabetes.

Background: The rising prevalence of type 2 diabetes in Australia is a public health concern, contributing to significant disease burden and economic costs. Text-message programs have been shown to improve health outcomes for people with type 2 diabetes, however they remain underutilized, and no evidence exists on their cost-effectiveness or costs of scale up to a population level in Australia. This study aimed to determine the cost-effectiveness and cost-utility of a 6-month text-message intervention (DTEXT) to improve glycated hemoglobin (HbA1c) and self-management behaviors for Australian adults with type 2 diabetes. Methods: A within-trial economic evaluation was conducted on the DTEXT randomized controlled trial. Incremental cost-effectiveness ratios (ICERs) were determined per 11 mmol/mol (1%) reduced HbA1c and per quality adjusted life year (QALY) gained, compared to usual care. Cost-effectiveness acceptability curves (CEAC) determined the probability of the intervention being cost-effective over a range of willingness to pay thresholds. A scenario analysis was conducted to determine how cost-effectiveness was impacted by using current implementation costs. Results: The DTEXT intervention cost AU$36 (INT$24) per participant, with an ICER of AU$311 (INT$211) per 11 mmol/mol (1%) reduced HbA1c. Based on HbA1c outcomes, DTEXT had a 33% probability of being effective and cost-saving. Based on the QALY outcomes, the intervention had only a 24% probability of being cost-effective. Scenario analysis indicated costs per participant of AU$13 (INT$9) to deliver the intervention, with a reduced incremental cost effectiveness ratio of AU$151 (INT$103) per 11 mmol/mol (1%) reduced HbA1c and a 38% probability of being effective and cost-saving. Conclusions: DTEXT was low cost and potentially scalable, but only had a low to moderate probability of being effective and cost saving. Further research should determine more targeted approaches that may improve cost-effectiveness. Trial Registration: ACTRN12617000416392.

Acceptability, feasibility and preliminary impact evaluation of a pilot text-message study on improving the health of Aboriginal people with, or at risk of, chronic disease in Australia.

ISSUE ADDRESSED: Aboriginal people experience higher rates of chronic disease than other Australians, largely due to modifiable risk factors. This study aimed to evaluate the acceptability, feasibility and preliminary impact of a pilot text-message program on improving the health of Aboriginal people with, or at risk of, chronic disease. METHODS: A before and after study using a convenience sample of Aboriginal Australian adults determined the impact of a 6-month healthy lifestyle text-message intervention on lifestyle behavioural measures including nutrition, physical activity and smoking. Process evaluation of participants and program facilitators determined program acceptability and feasibility. RESULTS: Twenty Aboriginal people enrolled in the study, with high study completion and program acceptability. The two program facilitators reported the low-cost automated text-message program to be highly acceptable, feasible to deliver and led to environmental program changes. Preliminary impact data showed significant improvements in vegetable consumption at 3 and 6 months, but not for other health outcome measures. CONCLUSIONS: The text-message program was highly acceptable and feasible to deliver, and has potential as an adjunct to usual care. Further research is required to determine program efficacy with a larger sample size. SO WHAT?: Text-messages to improve the health of Aboriginal people are highly acceptable, feasible to deliver and can complement existing community-led group programs. Further testing of this low-cost program is warranted to determine program efficacy.

Effectiveness of workshops to teach a home-based exercise program (BEST at Home) for preventing falls in community-dwelling people aged 65 years and over: a pragmatic randomised controlled trial.

BACKGROUND: Falls are a significant public health issue. There is strong evidence that exercise can prevent falls and the most effective programs are those that primarily involve balance and functional exercises, however uptake of such programs is low. Exercise prescribed during home visits by health professionals can prevent falls however this strategy would be costly to deliver at scale. We developed a new approach to teach home exercise through group-based workshops delivered by physiotherapists. The primary aim was to determine the effect of this approach on the rate of falls among older community-dwelling people over 12 months. Secondary outcomes included the proportion of people falling, fear of falling, physical activity, lower limb strength, balance and quality of life. METHODS: A randomised controlled trial was conducted among community-dwelling people aged ≥65 in New South Wales, Australia. Participants were randomised to either the intervention group (exercise targeting balance and lower limb strength) or control group (exercise targeting upper limb strength). RESULTS: A total of 617 participants (mean age 73 years, +SD 6, 64% female) were randomly assigned to the intervention group (n = 307) or control group (n = 310). There was no significant between-group difference in the rate of falls (IRR 0.91, 95% CI 0.64 to 1.29, n = 579, p = 0.604) or the number of participants reporting one or more falls (IRR 0.99, 95% CI 0.76 to 1.29, n = 579, p = 0.946) during 12 month follow-up. A significant improvement in the intervention group compared to control group was found for fear of falling at 3, 6 and 12 months (mean difference 0.50, 95% CI 0.2 to 0.8, p = 0.004; 0.39, 95% CI 0.001 to 0.8, p = 0.049; 0.46, 95% CI 0.006 to 0.9, p = 0.047, respectively), and gait speed at 3 months (mean difference 0.09 s, 95% CI 0.003 to 0.19, p = 0.043). No statistically significant between-group differences were detected for the other secondary outcomes. CONCLUSIONS: There was no significant intervention impact on the rate of falls, but the program significantly reduced fear of falling and improved gait speed. Other exercise delivery approaches are needed to ensure an adequate intensity of balance and strength challenge and dose of exercise to prevent falls.

Foods and beverages provided in out of school hours care services: an observational study.

INTRODUCTION: Out of school hours care (OSHC) is a fast-growing childcare setting in Australia, however the types of foods and beverages offered are relatively unknown. This study describes the food and beverages offered and investigates sector-level and setting-level factors which may impact OSHC in meeting the Australian Dietary Guidelines (ADG). METHODS: This cross-sectional, observational study was conducted in 89 OSHC services (between 2018 and 2019). Food and beverages offered, kitchen facilities and menus were captured via direct observation. Foods were categorised into five food groups or discretionary foods, based on the ADG, and frequencies determined. Short interviews with OSHC directors ascertained healthy eating policies, staff training, food quality assessment methods and food budgets. Fisher's exact test explored the influence of sector-level and setting-level factors on food provision behaviours. RESULTS: Discretionary foods (1.5 ± 0.68) were offered more frequently than vegetables (0.82 ± 0.80) (p < .001), dairy (0.97 ± 0.81) (p = .013) and lean meats (0.22 ± 0.54) (p < .001). OSHC associated with long day care and reported using valid food quality assessment methods offered more lean meats (p= .002, and p= .004). Larger organisations offered more vegetables (p = .015) and discretionary foods (p= .007). Menus with clearly worded instructions to provide fruits and vegetables daily offered more fruit (p= .009), vegetables (p < .001) and whole grains (p= .003). No other sector or setting-level factors were associated with services aligning with the ADG. CONCLUSION: Future interventions could benefit from trialling menu planning training and tools to assist OSHC services in NSW meet the ADG requirements.

Assessment of Feeding Practices and Mealtime Environments in Australian Family Daycare Services.

OBJECTIVE: Assess educators' feeding practices and mealtime environments in family daycare services and examine the factors associated with educators' feeding practices and mealtime environments. METHODS: Cross-sectional observational study of family daycare services (n = 33) in Australia. Best practices for mealtime environments and educator feeding practices were assessed during each mealtime using the Environment Policy Assessment and Observation instrument. Correlates assessed via survey included: socioeconomic status, main language spoken at home, early childhood career experience, and nutrition professional development. Descriptive statistics and independent t tests were calculated. RESULTS: Educators typically had higher scores, indicating better practices, for (the absence of) negative practices compared with positive practices. The only positive practice meeting best-practice standards was educators sitting with children during the meal. There were no significant correlations for educators' feeding practices or mealtime environment. CONCLUSIONS AND IMPLICATIONS: Educators may benefit from professional development targeting positive feeding practices and supportive mealtime environments.

A health and wellbeing programme for preadolescents in underserved Australian communities: child and stakeholder perspectives.

Social inequities in childhood affect children's health and development. Active In-Betweens is a weekly, healthy lifestyle and outdoor activity after-school programme, tailor-made for preadolescent children (9-12 year olds), incorporating a strengths-based, trauma-informed, co-designed and place-based approach. This study evaluated the extent to which the programme strategies and activities met the anticipated short- to medium-term programme outcomes during its first year of operation in two socio-economically disadvantaged housing communities in New South Wales, Australia. A qualitative case study used data from semi-structured interviews with child participants (n = 11) and key stakeholders (n = 10). A broad range of positive outcomes were described. Children's feedback indicated they had experienced opportunities which facilitated the development of new physical activity skills; new healthy eating experiences and knowledge; positive relationships with peers and facilitators and new connections with neighbourhood programmes and outdoor environments. Stakeholders valued the programme for the positive outcomes they observed among the children and the strong organizational partnerships which resulted. The importance of skilled facilitators to deliver the programme, the engagement of local stakeholders and a long-term commitment to programme delivery, with secure funding to ensure continuity, were clearly identified as integral for effective, sustainable outcomes.

The barriers and enablers to implementing the New South Wales Healthy School Canteen Strategy in secondary schools in the Illawarra and Shoalhaven regions - A qualitative study.

ISSUE ADDRESSED: In 2017, the New South Wales Healthy School Canteen Strategy (Strategy) was introduced into primary and secondary schools. Studies have reported that secondary schools have a lower level of compliance with healthy canteen policies compared with primary schools. This study aims to identify and describe the barriers and enablers to implementing the Strategy in Department of Education (DoE) secondary schools in the Illawarra and Shoalhaven regions. METHODS: The framework underpinning the study was the systems theory. Canteen managers (CM) and principals from the 21 DoE secondary schools in the Illawarra and Shoalhaven regions were invited to participate in semi-structured interviews. The interviews were structured around the five focus areas of the Strategy, including questions on school nutrition policies and the role of the canteen. Data were collated using the interview guides as a framework and qualitative content analysis, using manual coding, was undertaken. RESULTS: Eight (38%) schools participated with seven CMs and six principals interviewed. Barriers to implementing the Strategy included the changing role of the canteen, the increased demands placed on CMs and inconsistencies between the school food environment and the Strategy. Enablers included monitoring implementation, and internal and external support. This study also recognised that previously identified barriers to healthy canteen strategy implementation are ongoing. CONCLUSIONS: The school canteen is an integral part of the school environment and therefore needs whole-of-school support if successful implementation of the Strategy is to occur. SO WHAT: Addressing the barriers and promoting the enablers identified in this study will support better nutrition policy implementation in secondary schools.

Physical activity in out of school hours care: an observational study.

BACKGROUND: Opportunities for physical activity within out of school hours care (OSHC) are not well documented in Australia. This study explored factors associated with children (5-12 years) meeting 30 min of moderate to vigorous physical activity (MVPA) while attending OSHC in the afternoon period. METHODS: A cross-sectional study, conducted in 89 OSHC services in New South Wales, Australia, serving 4,408 children. Each service was visited twice between 2018-2019. Physical activity promotion practices were captured via short interviews and System for Observing Staff Promotion of Physical Activity and Nutrition (SOSPAN). Physical activity spaces was measured (m2) and physical activity of 3,614 child days (42% girls), were collected using Acti-Graph accelerometers. Association between program practices and children accumulation of MVPA was tested using mixed effects logistic regression, adjusted by OSHC service and child. RESULTS: Twenty-six percent of children (n = 925) accumulated 30 min or more of MVPA. Factors associated with children reaching MVPA recommendations included: services scheduling greater amounts of child-led free play, both 30-59 min (OR 2.6, 95%CI 1.70, 3.98) and ≥ 60 min (OR 6.4, 95%CI 3.90, 10.49); opportunities for staff-led organised play of ≥ 30 min (OR 2.3, 95%CI 1.47, 3.83); and active games that engaged the majority of children (OR 1.7, 95%CI 1.11, 2.61). Children were less likely to meet MVPA recommendations if services played games with elimination components (OR 0.56, 95%CI 0.37, 0.86). CONCLUSION: Improvements to service-level physical activity promotion practices, specifically the type of physical activity scheduled and the structure of games, may be an effective strategy to increase MVPA of children attending OSHC afterschool in NSW, Australia.

Foods provided to children in family day care: an observational study.

OBJECTIVE: To assess the quality and quantity of foods and beverages provided to children aged 0-5 years in family day care and identify structural and sociodemographic factors associated with the nutritional quality of food provided. DESIGN: A cross-sectional study measured the food and beverages provided to children using weighed food records. The number of serves from different food groups was calculated according to the Australian Guide to Healthy Eating, and a healthy food provision index score was created. Associations between structural and sociodemographic factors and healthy food provision index scores were analysed using linear mixed models. SETTING: Family day care services in two large geographic areas in New South Wales, Australia. PARTICIPANTS: One hundred and four children in thirty-three family day care services. RESULTS: During attendance at childcare, most children met recommended servings of fruit but not dairy, vegetables, lean meat and meat alternatives and wholegrains. Discretionary foods exceeded recommendations. Children's age, socio-economic status and the type of main meal provided were significantly associated with the healthy food provision index score. CONCLUSIONS: Foods provided to children in family day care are aligned with dietary recommendations for fruit but not vegetables, dairy, lean meat and meat alternatives, wholegrains or discretionary foods. Interventions to promote healthy eating are needed to support families and educators to improve the nutritional quality of food provided to children.

Effectiveness and acceptability of a text message intervention (DTEXT) on HbA1c and self-management for people with type 2 diabetes. A randomized controlled trial.

OBJECTIVE: Determine the effectiveness and acceptability of a text message intervention (DTEXT) on HbA1c and self-management behaviors for Australian adults with type 2 diabetes. METHODS: Using intention to treat analysis and generalized estimating equations, this randomized controlled trial of 395 adults determined change in HbA1c at 3 and 6 months between the intervention and control group. Secondary outcomes included change in nutrition, physical activity, blood lipid profile, body mass index, quality of life, self-efficacy, medication taking and program acceptability. RESULTS: No significant difference was observed between the intervention or control group for HbA1c at 3 months (P = 0.23) or 6 months (P = 0.22). Significant improvements were seen in consumption of vegetables at 3 months (P < 0.001) and 6 months (P = 0.04); fruit at 3 months (P = 0.046) and discretionary sweet foods at 3 months (P = 0.02). No other significant effects seen. The intervention demonstrated high rates of acceptability (94.0%) and minimal withdrawal (1.5%). CONCLUSIONS: DTEXT was an acceptable text message intervention that improved some nutritional behaviors in people with type 2 diabetes, but did not significantly improve HbA1c or other outcomes. Further research is required to optimize DTEXT. PRACTICE IMPLICATIONS: DTEXT provides an acceptable, feasible form of self-management support that may complement existing diabetes care.

Healthy eating and physical activity environments in out-of-school hours care: an observational study protocol.

INTRODUCTION: Childcare settings have been widely identified as important venues for promoting healthy lifestyles to children. Out-of-school hours care (OSHC) is a rapidly growing childcare service, yet there has been limited research reported on healthy eating and physical activity (HEPA) environments within the Australian OSHC setting. This research aims to describe the HEPA environments related to foods and beverages served, staff behaviours and child physical activity levels across two local health districts within New South Wales, Australia. This study will provide evidence to support future interventions and policies in Australian OSHC settings. METHODS AND ANALYSIS: A cross-sectional study design will be used to describe the food and beverages provided and child activity levels, and report on environmental correlates. OSHC programmes will be visited on non-consecutive weekdays between 2018 and 2020. The frequency of foods and beverages offered will be observed and categorised into food groups aligned to the Australian Dietary Guidelines. Children's physical activity will be measured using ActiGraph wGT3X-BT accelerometers. Staff behaviour will be captured via direct observation and the System for Observing Staff Promotion of Activity and Nutrition. Short interviews with programme directors will gather contextual information about OSHC practices and policies. ETHICS AND DISSEMINATION: Findings will be disseminated through peer-reviewed scientific journals, conference presentations and individualised feedback to each participating service. Ethical approval was granted by the University of Wollongong Human Research Ethics Committee (HE17/490).

DTEXT - text messaging intervention to improve outcomes of people with type 2 diabetes: protocol for randomised controlled trial and cost-effectiveness analysis.

BACKGROUND: Diabetes prevalence is rapidly increasing, with type 2 diabetes predicted to be the leading contributor of non-communicable disease in Australia by 2020. It is anticipated that rates of type 2 diabetes will continue to increase if factors such as overweight and obesity, low physical activity and poor nutrition are not addressed. The majority of Australians with type 2 diabetes do not meet the guidelines for optimal diabetes management, and access to diabetes education is limited. This highlights the need for new interventions that can reduce existing barriers to diabetes education, attain greater population reach and support self-management strategies for people with type 2 diabetes. Mobile phone text messages have shown promising results as an intervention for people with chronic disease. They have the ability to achieve high levels of engagement and broad population reach, whilst requiring minimal resources. There is however, no evidence on the effect of text messaging to improve the health of people with type 2 diabetes in Australia. METHODS/DESIGN: This randomised controlled trial aims to investigate if a 6 month text message intervention (DTEXT) can lead to improvements in glycated haemoglobin (HbA1c) and diabetes self-management among Australian residents in New South Wales (NSW) with type 2 diabetes. Community dwelling adults (n = 340) will be recruited with the primary outcome being change in HbA1c at 6 months. Secondary outcomes include behaviour change for diabetes self-management, self-efficacy, quality of life and intervention acceptability. An economic evaluation will be conducted using a funder plus patient perspective. DISCUSSION: This study will provide evidence on the effectiveness and cost effectiveness of a text message intervention to reduce HbA1c and enhance self-management of type 2 diabetes in the Australian population. If successful, this intervention could be used as a model to complement and extend existing diabetes care in the Australian health care system. TRIAL REGISTRATION: The study has been registered with the Australian New Zealand Clinical Trials Registry, Trial ID: ACTRN12617000416392 . Registered: 23 March 2017.

Trial Protocol: Home-based exercise programs to prevent falls and upper limb dysfunction among community-dwelling older people: study protocol for the BEST (Balance Exercise Strength Training) at Home randomised, controlled trial.

INTRODUCTION: Falling when older is a major public health issue. There is compelling evidence to show that specific exercise programs can reduce the risk and rate of falls in community-dwelling older people. Another major health issue for older people living in the community is upper limb dysfunction, including shoulder pain. Home-based exercise programs appeal to some older people, due to their convenience. RESEARCH QUESTIONS: This trial aims to determine the effectiveness and cost-effectiveness of a home-based lower limb exercise program compared with a home-based upper limb exercise program to prevent falls and upper limb dysfunction among community-dwelling people aged 65+ years. DESIGN: Randomised, controlled trial. PARTICIPANTS AND SETTING: A total of 576 community-dwelling people will be recruited from the Illawarra and Shoalhaven regions of New South Wales, Australia. INTERVENTION: Participants will be randomised to either a home-based lower limb exercise intervention or a home-based upper limb exercise intervention. The lower limb program is designed to improve balance and strength in the lower limbs. The upper limb program is designed to improve upper limb strength and mobility. Participants will attend three group-based instruction sessions to learn and progress the exercises, and will be instructed to perform the exercises three times per week at home for 12 months. OUTCOME MEASURES: The two primary outcomes will be fall rates, recorded with monthly calendars for a 12-month period, and upper limb dysfunction, measured with the Disability of the Arm, Shoulder and Hand questionnaire. Secondary outcomes will include: lower limb strength and balance; shoulder strength and mobility; physical activity; quality of life; attitudes to exercise; proportion of fallers; fear of falling; and health and community service use. The cost-effectiveness of both exercise programs from a health and community service provider perspective will be evaluated. ANALYSIS: Negative binomial regression models will be used to estimate the between-group difference in fall rates. Modified Poisson regression models will be used to compare groups on dichotomous outcome measures. Linear regression models will be used to assess the effect of group allocation on the continuously scored measures, after adjusting for baseline scores. Two economic evaluations will be conducted: the first will assess cost-effectiveness of the lower limb program compared with the upper limb program; and the second will assess cost-effectiveness of the upper limb program compared with the lower limb program. DISCUSSION: If effective, the trial will provide a model for both upper limb and lower limb exercise programs that can be performed at home and implemented at scale to community-dwelling older adults.

Effects of a Pedometer-Based Telephone Coaching Intervention on Physical Activity Among People with Cardiac Disease in Urban, Rural and Semi-Rural Settings: A Replication Study.

BACKGROUND: This study aimed to determine the replicability of a pedometer-based telephone coaching intervention by comparing the outcomes of a study conducted in rural and urban settings to a study that previously found the same intervention effective in a semi-rural setting. METHODS: Replication studies are conducted to assess whether an efficacious intervention is effective in multiple different settings. This study compared the outcomes of a pedometer-based coaching intervention implemented in urban and rural settings (replication study) with the same intervention implemented in a semi-rural setting (reference study) on physical activity levels. RESULTS: Improvements in total weekly physical activity time in the replication study were significant from baseline to six weeks (p<0.001 urban, p=0.006 rural) and remained significant at six months (p=0.029 urban, p=0.005 rural). These increases were comparable to those achieved in the original efficacy trial conducted in a semi-rural setting. CONCLUSIONS: The pedometer-based telephone coaching intervention increases physical activity levels of people with cardiac disease referred to a CR program in diverse settings. This replication study indicates the suitability of this minimal contact, low-cost intervention for further scaling-up to address unmet need in community-dwelling cardiac patients.

Cost-effectiveness of a Population-based Lifestyle Intervention to Promote Healthy Weight and Physical Activity in Non-attenders of Cardiac Rehabilitation.

BACKGROUND: To evaluate the long-term cost-effectiveness of two home-based cardiac rehabilitation (CR) interventions (Healthy Weight (HW) and Physical Activity (PA)) for patients with cardiovascular disease (CVD), who had been referred to cardiac rehabilitation (CR) but had not attended. The interventions consisted of pedometer-based telephone coaching sessions on weight, nutrition and physical activity (HW group) or physical activity only (PA group) and were compared to a control group who received information brochures about physical activity. METHODS: A cost-effectiveness analysis was conducted using data from two randomised controlled trials. One trial compared HW to PA (PANACHE study), and the second compared PA to usual care. A Markov model was developed which used one risk factor, body mass index (BMI) to determine the CVD risk level and mortality. Patient-level data from the trials were used to determine the transitions to CVD states and healthcare related costs. The model was run for separate cohorts of males and females. Univariate and probabilistic sensitivity analysis were conducted to test the robustness of the results. RESULTS: Given a willingness-to-pay threshold of $50,000/QALY, in the long run, both the HW and PA interventions are cost-effective compared with usual care. While the HW intervention is more effective, it also costs more than both the PA intervention and the control group due to higher intervention costs. However, the HW intervention is still cost-effective relative to the PA intervention for both men and women. Sensitivity analysis suggests that the results are robust. CONCLUSION: The results of this paper provide evidence of the long-term cost-effectiveness of home-based CR interventions for patients who are referred to CR but do not attend. Both the HW and PA interventions can be recommended as cost-effective home-based CR programs, especially for people lacking access to hospital services or who are unable to participate in traditional CR programs.
