How long does it take to scale-up obesity prevention interventions?

OBJECTIVE: The scale-up of evidence-based interventions is necessary to reverse high rates of obesity. However, scale-up doesn't occur frequently nor in a timely manner. While it has been estimated that takes 14-17 years for research translation to occur, the time taken to scale-up prevention interventions is largely unknown. This study examined the time taken to scale-up obesity prevention interventions across four scale-up pathways. METHODS: A sample of obesity prevention interventions that had been scaled-up or implemented at scale were found using a structured search strategy. Included interventions were mapped against four scale-up pathways and timeframes associated with each stage of the scale-up pathway were identified to determine the time taken to scale-up. RESULTS: Of the 90 interventions found that were scaled-up to at least a city-wide level, less than half reported a comprehensive research pathway to scale-up and a third did not report any evidence of efficacy or effectiveness prior to scale-up. The time taken to scale-up ranged from 0 to 5 years depending on the pathway taken. Those following a comprehensive pathway took approximately 5 years to scale-up, while interventions that had only one evidence generating step took between 1 and 1.5 years to scale-up. For the remaining interventions, scale-up occurred immediately post-development without evidence generation. CONCLUSIONS: Our findings indicate that the scale-up of obesity prevention interventions can occur more quickly than previous estimates of 14-17 years. Our findings support previous research that scale-up of interventions occurs through a variety of pathways and often scale-up occurs in absence of prior evidence of effectiveness.

Benchmarking online food delivery applications against menu labelling laws: a cross-sectional observational analysis.

OBJECTIVE: It is unknown how well menu labelling schemes that enforce the display of kilojoule (kJ) labelling at point-of-sale have been implemented on online food delivery (OFD) services in Australia. This study aimed to examine the prevalence of kJ labelling on the online menus of large food outlets with more than twenty locations in the state or fifty locations nationally. A secondary aim was to evaluate the nutritional quality of menu items on OFD from mid-sized outlets that have fewer locations than what is specified in the current scheme. DESIGN: Cross-sectional analysis. Prevalence of kJ labelling by large food outlets on OFD from August to September 2022 was examined. Proportion of discretionary ('junk food') items on menus from mid-sized outlets was assessed. SETTING: Forty-three unique large food outlets on company (e.g. MyMacca's) and third party OFD (Uber Eats, Menulog, Deliveroo) within Sydney, Australia. Ninety-two mid-sized food outlets were analysed. PARTICIPANTS: N/A. RESULTS: On company OFD apps, 35 % (7/23) had complete kJ labelling for each menu item. In comparison, only 4·8 % (2/42), 5·3 % (2/38) and 3·6 % (1/28) of large outlets on Uber Eats, Menulog and Deliveroo had complete kJ labelling at all locations, respectively. Over three-quarters, 76·3 % (345/452) of menu items from mid-sized outlets were classified as discretionary. CONCLUSIONS: Kilojoule labelling was absent or incomplete on a high proportion of online menus. Mid-sized outlets have abundant discretionary choices and yet escape criteria for mandatory menu labelling laws. Our findings show the need to further monitor the implementation of nutrition policies on OFD.

The socio-ecological determinants of help-seeking practices and healthcare access among young men: a systematic review.

Delayed engagement with health services is a key contributor to poorer health outcomes experienced by men. Patterns of health service usage which reduce the opportunity for disease prevention and health promotion appear to be especially prominent amongst young men. To identify the multiple and intersecting determinants of young men's help-seeking practices and health services usage, this review uses the social ecological model (SEM) to guide a critical synthesis of the literature on barriers and facilitators experienced by young men in accessing health services. A systematic review was conducted across five databases (MEDLINE, Embase, PsychINFO, CINAHL and Scopus). Included studies presented primary data regarding young men's (12-24 years) barriers and/or facilitators to seeking and accessing health care. Thirty-one studies (24 qualitative and 7 quantitative) underwent data extraction, quality appraisal and thematic analysis under the guiding framework of the SEM. Seven key themes were constructed, encapsulating the perceived barriers and facilitators to help-seeking and accessing health care experienced by young men, including masculine attitudes, health literacy, social pressure, service accessibility, economic factors, service characteristics and cultural attitudes. These findings highlight the complex interplay between the individual, interpersonal, organizational and societal factors impacting young men's healthcare engagement. They also illuminate avenues for multifaceted, context-specific interventions to enhance healthcare accessibility for this group, including addressing health literacy gaps, providing culturally sensitive care and reducing cost barriers.

A cross-sectional study of Australian teachers' health: are work-related factors associated with lifestyle behaviours?

Teacher's lifestyle behaviours are important because they lead to positive health outcomes for teachers themselves and because teachers model behaviour to their students. This cross-sectional study examined the lifestyle behaviours of a large sample of teachers in New South Wales (NSW), Australia and assessed the association between work-related factors and lifestyle behaviours. From February to October 2021, data were collected on the lifestyle behaviours, work-related factors and socio-demographics of primary and secondary school teachers in NSW, via an online survey. Associations between individual work-related factors and lifestyle behaviours were modelled using logistic regression and adjusted for sex, age, number of children and geographic location. Most of our survey sample (n = 1136) were women (75%) and 53% were reported as having overweight or obesity. Only 23% of teachers met the recommended physical activity guidelines, 39% met fruit intake guidelines, 9% met vegetable intake guidelines and 58% met healthy sleep guidelines. Most teachers (78%) met the recommendation of sugar-sweetened beverage consumption, 89% were not current smokers, but only 46% met the recommended alcohol consumption guidelines. Hours worked, teaching load, school sector and teacher role were associated with one or more lifestyle behaviours after adjusting for the demographic variables. This study highlights the need for additional support to improve the health-related behaviours of teachers in NSW. Policymakers should recognize the negative impact of high workloads on teachers' health-related behaviours, increasing their risk of chronic disease.

Twelve-month effectiveness of telephone and SMS support to mothers with children aged 2 years in reducing children's BMI: a randomized controlled trial.

BACKGROUND/OBJECTIVES: Few quality intervention studies have assessed whether a combined telephone and short message service (SMS) intervention to mothers is effective in reducing BMI and obesity risk behaviors of children at 3 years of age. This study aimed to assess effectiveness of telephone and SMS support in reducing children's body mass index (BMI) and obesity risk behaviors. SUBJECTS/METHODS: A randomized controlled trial (RCT) with 662 women of 2-year-old children (with the proportion of overweight and obesity being similar to the general population) was conducted in Sydney, Australia, March 2019-October 2020. The mothers in the intervention group received three telephone support sessions plus SMS messages and mailed-intervention-booklets over a 12 months period i.e., 24-26, 28-30, and 32-34 months of the child's age. Mothers in the control group received usual care and two mailed booklets on information not related to the intervention. The primary outcome was child's BMI at 3 years of age. Secondary outcomes were children's dietary and activity behaviors. All outcome measures were based on mothers' self-report using standardized tools due to COVID-19 pandemic restrictions. RESULTS: 537 (81%) mothers completed the post-intervention assessment at 3 years with only 470 (71%) children having weight and height measures. Multiple imputation analysis showed no statistically significant difference in mean BMI between the groups. Children in the intervention group were more likely not to eat in front of the TV [AOR 1.79 (95% CI 1.17-2.73), P = 0.008], more likely to meet the dietary recommendations [AOR 1.73 (95% CI 0.99-3.02), P = 0.054] and meet the activity recommendations [AOR 1.72 (95% CI 1.11-2.67), P = 0.015] than those in the control group respectively. Among those with an annual household income (

Systems map of interventions to improve dietary intake of pre-school aged children: A scoping review.

Implementation and sustaining impact of early childhood nutrition interventions in practice remains a challenge. An understanding of the extent to which determinants across multiple levels of the food system are being addressed may improve success. This literature review aimed to synthesise the evidence on interventions targeting dietary intake and eating behaviours in preschool children using a systems approach. Eligible studies included intervention studies targeting the dietary intake of preschool children aged 2-5 years in high income countries, published in English after January 2000. Interventions were categorised to the Determinants of Nutrition and Eating (DONE) framework for children developed and evaluated by experts across multiple fields. The framework maps and ranks 411 factors driving eating behaviours and nutrition and can be used to systematically summarise determinants. DONE ranks each determinant for its perceived research priority. A total of 160 eligible studies were identified. Most interventions targeted interpersonal (n = 101, 63.1%) and individual (n = 85, 53.1%) level determinants, with fewer targeting environmental (n = 55, 34.4%) and policy level (n = 17, 10.6%) determinants. The most frequently addressed determinants were Parental Resources and Risk Factors (n = 85) and Children's Food Knowledge, Skills and Abilities (n = 67). These determinants had a Moderate research priority rating. Home Food Availability and Accessibility at the environmental level is classified as the highest research priority, however, only 15 of 160 interventions addressed this determinant. This review highlights home food availability and accessibility as potential leverage points for future interventions to improve children's dietary intake and eating behaviours.

Associations of dietary and sedentary behaviours of pregnant women with their children's birth weight: findings from the CHAT trial in Australia.

OBJECTIVE: To examine the associations of pregnant women's dietary and sedentary behaviours with their children's birth weight. DESIGN: Secondary data analysis was conducted using data from a randomised controlled trial, Communicating Healthy Beginnings Advice by Telephone, conducted in Australia. Information on mothers' socio-demographics, dietary and sedentary behaviours during pregnancy was collected by telephone survey at the third trimester. Birth weight data were extracted from the child's health record book. Multinomial logistic regression models were built to examine the associations of pregnant women's dietary and sedentary behaviours with children's birth weight. SETTING: Participating families. PARTICIPANTS: Pregnant women and their children. RESULTS: A total of 1132 mother-child dyads were included in the analysis. The majority of infants (87 %, n 989) were of normal birth weight (2500 g to <4000 g), 4 % (n 50) had low birth weight (<2500 g) and 8 % (n 93) had macrosomia (≥4000 g). Mothers who ate processed meat during pregnancy were more likely to have macrosomia (adjusted risk ratio (ARR) 1·80, 95 % CI (1·12, 2·89)). The risk of macrosomia decreased as the number of dietary recommendations met by mothers increased (ARR 0·84, 95 % CI (0·71, 0·99)). Children's birth weight was not associated with mothers' sedentary time. Children's low birth weight was not associated with mothers' dietary and sedentary behaviours during pregnancy. CONCLUSION: Maternal consumption of processed meat during pregnancy was associated with an increased risk of macrosomia. Increasing number of dietary recommendations met by mothers was associated with a lower risk of macrosomia. The findings suggested encouraging pregnancy women to meet dietary recommendation will benefit children's birth weight.

Evaluating the effect of a 12-month youth advisory group on adolescent's leadership skills and perceptions related to chronic disease prevention research: a mixed-methods study.

BACKGROUND: Youth Advisory Groups (YAGs) represent a promising method to engage adolescents in research of relevance to them and their peers. However, YAGs are rarely implemented or evaluated in chronic disease prevention research. The aims of this study were firstly, to evaluate the effect of participation in a 12-month YAG on adolescents' leadership skills and perceptions related to chronic disease prevention research and secondly, to evaluate the process of establishing and facilitating a 12-month YAG and identify barriers and enablers to establishment and facilitation. METHODS: This study was a 12-month pre-post study. Eligible participants were adolescents (13-18-years) and current members of an established YAG. Data collection involved online surveys and semi-structured interviews at baseline, six-months and 12-months follow-up. Participatory outcomes such as self-efficacy, leadership skills, and collective participation were derived from Youth Participatory Action Research Principles (YPAR), and the Lansdown-UNICEF conceptual framework for measuring outcomes of adolescent participation. Process evaluation data were captured via meeting minutes, Slack metrics and researcher logs. Quantitative data was analysed using descriptive statistics and qualitative data was thematically analysed using a reflexive thematic analysis approach. RESULTS: Thirteen (13/16) YAG youth advisors consented to participate in the evaluation study (mean age 16.0 years, SD 1.3; 62% (8/13) identified as female). Survey data assessing participatory outcomes found an increase in leadership and life skills scores over 12-months (+ 8.90 points). Semi-structured interview data collected over the 12-month term revealed three key themes namely: influence, empowerment, and contribution. Comparison of pre-post themes determined a positive trend at follow-ups, demonstrating improved participatory outcomes. Process indicators revealed that at 12-month follow-up the YAG was implemented as planned. Semi-structured interview data determined barriers to YAG facilitation included time and limited face-to-face components, while enablers to YAG facilitation included flexibility, accessible delivery methods, and a supportive adult facilitator. CONCLUSION: This study found that a YAG fostered positive participatory outcomes and unique opportunities for youth participants. A successful YAG based on YPAR principles requires researchers to ensure YAG establishment and facilitation is an iterative process. Taking into consideration important barriers and enablers to YAG facilitation ensures adolescent engagement in a YAG is both meaningful and impactful.

Do associations of physical activity and sedentary behaviour with cardiovascular disease and mortality differ across socioeconomic groups? A prospective analysis of device-measured and self-reported UK Biobank data.

OBJECTIVE: To examine if individual-level and area-level socioeconomic status (SES) modifies the association of moderate-to-vigorous physical activity (MVPA), domain-specific physical activity and sedentary behaviour with all-cause mortality (ACM) and incident cardiovascular disease (CVD). METHODS: We used self-reported (International Physical Activity Questionnaire short form) and accelerometer-measured physical activity and sedentary behaviour data from the UK Biobank. We created an individual-level composite SES index using latent class analysis of household income, education and employment status. The Townsend Index was the measure of area-level SES. Cox proportional hazards regression models stratified across SES were used. RESULTS: In 328 228 participants (mean age 55.9 (SD 8.1) years, 45% men) with an average follow-up of 12.1 (1.4) years, 18 033 deaths and 98 922 incident CVD events occurred. We found an increased ACM risk of low physical activity and high sedentary behaviour and an increased incident CVD risk of low accelerometer-measured moderate-to-vigorous physical activity (ACCEL_MVPA) and high sitting time. We observed statistically significant interactions for all exposures in ACM analyses by individual-level SES (p<0.05) but only for screen time in area-level SES-ACM analysis (p<0.001). Compared with high self-reported moderate-to-vigorous physical activity (IPAQ_MVPA), adjusted ACM HRs for low IPAQ_MVPA were 1.14 (95% CI 1.05 to .25), 1.15 (95% CI 1.06 to 1.24) and 1.22 (95% CI 1.13 to 1.31) in high, medium and low individual-level SES, respectively. There were higher detrimental associations of low ACCEL_MVPA with decreasing area-level SES for both outcomes and of high screen time with ACM in low area-level SES. CONCLUSION: We found modest evidence suggesting that the detrimental associations of low MVPA and high screen time with ACM and incident CVD are accentuated in low SES groups.

An analysis of current obesity strategies for adolescents in NSW against best practice recommendations: Implications for researchers, policymakers and practitioners.

ISSUE ADDRESSED: Obesity is a significant health challenge facing adolescents. There is a critical need for government action to support all adolescents to improve risk factors for obesity. This study critically appraised initiatives, guidelines and policies (termed "strategies") from local health districts (LHDs), speciality health networks and Primary Health Networks (PHNs) across New South Wales (NSW), relevant to the prevention and management of obesity amongst adolescents and compare these to best practice recommendations. METHODS: We critically appraised strategies against best practice recommendations that included support, access, responsiveness to needs, supportive environment, monitoring and evaluation and health equity. Strategies were collected by systematically searching websites of 15 LHDs, one speciality health network and 10 PHNs. RESULTS: There was evidence of strategies regarding adolescent obesity prevention and management across all best practice recommendations. There was limited evidence of adolescent consumer participation, digital strategies for health services and online health information. There were minimal targeted public or school-based education campaigns and interventions on physical activity or nutrition. Place-based approaches such as sports and recreation facilities were not included in policies regarding the sale of healthy food and drinks. Evaluation evidence across all strategies was minimal. CONCLUSIONS: Numerous strategies are being implemented across NSW to address adolescent obesity. Despite this, the alignment of strategies with best practice recommendations is poor and evidence of progress in tackling adolescent obesity remains unclear. SO WHAT?: Opportunities to generate and translate best practice evidence within government strategies for obesity must be prioritised with embedded measurement and evaluation plans.

Hope and sadness: Balancing emotions in tobacco control mass media campaigns aimed at smokers.

ISSUE ADDRESSED: Australia has smoking prevalence of less than 15% among adults, but there are concerns that the rates of decline have stabilised. Sustained mass media campaigns are central to decreasing prevalence, and the emotions evoked by campaigns contribute to their impact. This study investigates the association between potential exposure to campaigns that evoke different emotions on quitting salience (thinking about quitting), quitting intentions and quitting attempts. METHODS: Data on quitting outcomes were obtained from weekly cross-sectional telephone surveys with adult smokers and recent quitters between 2013 and 2018. Campaign activity data were collated, and population-level potential campaign exposure was measured by time and dose. RESULTS: Using multivariate analyses, a positive association between potential exposure to 'hope' campaigns and thinking about quitting and intending to quit was noted, but no association was seen with quit attempts. Potential exposure to 'sadness' evoking campaigns was positively associated with quitting salience and negatively associated with quit attempts, whereas those potentially exposed to campaigns evoking multiple negative emotions (fear, guilt and sadness) were approximately 30% more likely to make a quit attempt. CONCLUSIONS: This study suggests a relationship between the emotional content of campaigns, quitting behaviours. Campaign planners should consider campaigns that evoke negative emotions for population-wide efforts to bring about quitting activity alongside hopeful campaigns that promote quitting salience and quitting intentions. The emotional content of campaigns provides an additional consideration for campaigns targeting smokers and influencing quitting activity. SO WHAT?: This study demonstrates the importance of balancing the emotional content of campaigns to ensure that campaign advertising is given the greatest chance to achieve its objectives. Utilising campaigns that evoke negative emotions appear to be needed to encourage quitting attempts but maintaining hopeful campaigns to promote thinking about quitting and intending to quit is also an important component of the mix of tobacco control campaigns.

Joint associations of social health and movement behaviours with mortality and cardiovascular disease: an analysis of 497,544 UK biobank participants.

BACKGROUND: Poor physical activity and excessive sedentary behaviour are well-established risk factors for morbidity and mortality. In the presence of emerging social problems, including loneliness and social isolation, these risks may be even greater. We aimed to investigate the joint effects of social health and movement behaviours on mortality and cardiovascular disease (CVD). METHODS: 497,544 UK Biobank participants were followed for an average of 11 years. Loneliness and social isolation were measured via self-report. Physical activity was categorised around current World Health Organisation (WHO) guidelines as low (< 600 metabolic equivalent of task [MET]-mins/week), moderate (600 < 1200) and high (≥ 1200). Sedentary behaviour was classified as low (≤ 3.5 h/day), moderate (3.5 ≤ 5) and high (> 5.5). We derived 24 social health-movement behaviour combinations, accordingly. Mortality and hospitalisations were ascertained to May 2020 for all-cause and CVD mortality, and non-fatal cardiovascular events. RESULTS: Social isolation amplified the risk of both all-cause and CVD death across all physical activity and sedentary levels (hazard ratio, 95% confidence interval [HR, 95% CIs] for all-cause mortality; 1.58 [1.49 to 1.68] for low active-isolated vs. 1.26 [1.22 to 1.30] for low active-not isolated). Loneliness was only found to amplify the risk of death from cardiovascular disease among the high active and low sedentary participants. Loneliness and social isolation did not add to the risk of non-fatal cardiovascular events across most activity levels. CONCLUSION: The detrimental associations of poor physical activity and sedentary behaviour with mortality were consistently amplified by social isolation. Our study supports the need to target the socially isolated as a priority group in preventive public health strategies.

Psychometric assessment of scales for measuring loneliness and social isolation: an analysis of the household, income and labour dynamics in Australia (HILDA) survey.

BACKGROUND: Loneliness and social isolation are increasingly recognised as global public health threats, meaning that reliable and valid measures are needed to monitor these conditions at a population level. We aimed to determine if robust and practical scales could be derived for conditions such as loneliness and social isolation using items from a national survey. METHODS: We conducted psychometric analyses of ten items in two waves of the Household, Income and Labour Dynamics in Australia Survey, which included over 15,000 participants. We used the Hull method, exploratory structural equation modelling, and multidimensional item response theory analysis in a calibration sample to determine the number of factors and items within each factor. We cross-validated the factor structure using confirmatory factor analysis in a validation sample. We assessed construct validity by comparing the resulting sub-scales with measures for psychological distress and mental well-being. RESULTS: Calibration and cross-validation consistently revealed a three-factor model, with sub-scales reflecting constructs of loneliness and social isolation. Sub-scales showed high reliability and measurement invariance across waves, gender, and age. Construct validity was supported by significant correlations between the sub-scales and measures of psychological distress and mental health. Individuals who met threshold criteria for loneliness and social isolation had consistently greater odds of being psychologically distressed and having poor mental health than those who did not. CONCLUSIONS: These derived scales provide robust and practical measures of loneliness and social isolation for population-based research.

Modifiable predictors of breastfeeding status and duration at 6 and 12 months postpartum.

BACKGROUND: Breastfeeding practices are determined by complex multilevel factors. This study assessed pregnant women's knowledge of breastfeeding and intention to breastfeed and investigated modifiable predictors for breastfeeding status (exclusive or any breastfeeding) and duration at 6 and 12 months postpartum. MATERIALS AND METHODS: Longitudinal data were extracted from a trial in Sydney, Australia, 2017-19. Women (n = 1155) were recruited from antenatal clinics and followed up for telephone interviews at baseline (third trimester), then at 6 and 12 months postpartum. Data collected included mothers' demographics; knowledge of breastfeeding and intention to breastfeed; work status; support from caregivers; breastfeeding environment; breastfeeding status and duration. Multiple logistic and Cox regression models were built to identify predictors for breastfeeding. RESULTS: At baseline, most mothers knew the recommendation to exclusively breastfeed until 6 months (66%) and the benefits (65%). The modifiable predictors for breastfeeding duration at 12 months included the following: mothers' knowledge of the recommendation (adjusted hazard ratio (AHR) 0.73, 95% confidence interval (CI) 0.60-0.90) and the benefits of exclusive breastfeeding (AHR 0.68, 95% CI 0.55-0.82), intention to meet the recommendation (AHR 0.76, 95% CI 0.63-0.93), and intention to breastfeed for two years (AHR 0.38, 95% CI 0.27-0.52) measured at baseline; mothers not working or studying (AHR 0.70, 95% CI 0.55-0.89), having support from other caregivers (AHR 0.64, 95% CI 0.43-0.96), and having breastfeeding women around (AHR 0.80, 95% CI 0.65-0.98) measured at 6 months. CONCLUSIONS: Support for women to meet the breastfeeding recommendations should commence during pregnancy and focus on breastfeeding education and enabling environments.

Community support for policy interventions targeting unhealthy food environments in public institutions.

ISSUE ADDRESSED: Understanding community support for obesity prevention policy is important for developing effective preventive health action. This study assessed support for a range of obesity prevention interventions, including food environment policies designed to improve healthy food and drink availability and promotion within public institutions. METHODS: An online cross-sectional survey was completed by 2006 NSW adults. Questions explored attitudes and beliefs about obesity, the importance of government-led prevention and support for eight obesity prevention interventions. Regression analyses examined associations between intervention support and sociodemographic, attitudinal and behavioural characteristics. RESULTS: Most respondents (80%) believed obesity was a large problem and that poor individual choices (86%) and the widespread availability of unhealthy food and drink (78%) contributed to the issue. There was moderate to high support for most (n = 7) initiatives. Support for food environment policies was highest for schools (76%-82%) and hospitals (67%-79%). Supporters and opponents rationalised opinions based on perceived effectiveness, the government's role and cost benefits. Opponents were a minority, but principles of autonomy were predominant. Attributing obesity to environment-related factors, and personal lower SSB consumption strongly predicted support. CONCLUSION: There is a significant recognition of the obesity issue and strong support for policies designed to improve the availability and promotion of healthy food and drink in public institutions, particularly in schools and hospitals. SO WHAT?: Substantial community support for healthy food environment policies in schools and hospitals warrants continued implementation in NSW. This may foster further acceptance for wider implementation. Our findings could inform the framing of policy advocacy messages.

Towards healthier food choices for hospital staff and visitors: impacts of a healthy food and drink policy implemented at scale in Australia.

OBJECTIVE: To determine the impact of a healthy food and drink policy on hospital staff and visitors' food purchasing behaviours, and their awareness and support for the changes introduced. DESIGN: Two repeated cross-sectional surveys, consisting of intercept interviews and observations of food items purchased, were conducted before (March-July 2018) and after (April-June 2019) the target date for implementation of thirteen food and drink practices (31 December 2018). Food purchases were coded as 'Everyday' (healthy) or 'Occasional' (unhealthy). SETTING: Ten randomly selected New South Wales public hospitals, collection sites including hospital entrances and thirteen hospital cafés/cafeterias. PARTICIPANTS: Surveys were completed by 4808 hospital staff and visitors (response rate 85 %). The majority were female (63 %), spoke English at home (85 %) and just over half had completed tertiary education (55 %). RESULTS: Significant increases from before to after the implementation target date were found for policy awareness (23 to 42 %; P < 0·0001) and support (89 to 92 %; P = 0·01). The proportion of 'Everyday' food purchases increased, but not significantly (56 to 59 %; P = 0·22); with significant heterogeneity between outlets (P = 0·0008). Overall, younger, non-tertiary-educated adults, visitors and those that spoke English at home were significantly less likely to purchase 'Everyday' food items. Support was also significantly lower in males. CONCLUSIONS: The findings provide evidence of strong policy support, an increasing awareness of related changes and a trend towards increased 'Everyday' food purchasing. Given the relatively early phase of policy implementation, and the complexity of individual food purchasing decisions, longer-term follow-up of purchasing behaviour is recommended following ongoing implementation efforts.

Correlates of Domain-Specific Physical Activity Among Older Adults in Six Low- to Middle-Income Countries: Analysis of Nationally Representative Samples From Study of Global Aging and Adult Health (SAGE) (Wave 1).

The correlates of physical activity differ across domains. The authors explored the contribution of domain-specific physical activity to total physical activity and examined how different sociodemographic and social capital-related variables are associated with different physical activity domains in older adults, using nationally representative samples from six low- to middle-income countries. Activity at work and home combined plays an important role in contributing to total physical activity, while leisure-time physical activity accounted for an extremely small proportion. Some correlates of physical activity were similar across countries, such as working status and structural social capital, while other associations were country specific. Promoting structural social capital, trust, and perceived safety may confer positive benefits on older adults' activity.

Impact and acceptance of a state-wide policy to remove sugar-sweetened beverages in hospitals in New South Wales, Australia.

ISSUE ADDRESSED: Policy and environmental approaches can reduce the accessibility and purchasing of sugar-sweetened beverages (SSBs), potentially reducing overweight and obesity. This study examined the impact of a state-wide policy on removal of SSBs from sale in NSW public hospitals (launched July 2017), and explored consumer awareness and support. METHODS: A convenience sample of 81 food outlets in 26 hospitals were audited for SSB availability before and after the target date for SSB removal (31 December 2017). An interviewer-administered intercept survey in 10 randomly selected hospitals (March-May 2018), assessed staff and visitors' awareness of and support for SSB removal. Descriptive and χ2 analyses assessed differences in: SSB availability; staff and visitor awareness and support. Open-ended survey responses were thematically analysed. RESULTS: The proportion of outlets that removed SSBs increased from 58.0% to 96.3% (P < .001). The majority (79.5%) of the 2394 surveyed supported SSB removal, with nearly half (48.4%) reporting it would improve people's health. A minority (13.4%) did not support SSB removal, more than half (61.4%) of those said individuals should have free choice. More staff than visitors were aware of the change (61.9% vs 31.2%; P < .0001). CONCLUSIONS: Availability of SSBs in NSW hospitals was significantly reduced after implementation of a policy to remove them from sale. There was strong staff and visitor support for the initiative. SO WHAT?: This study provides clear evidence that a policy designed to provide a healthy hospital retail drink environment can be successfully implemented at scale with high levels of support from staff and visitors. SUMMARY: A state-wide policy initiative to remove SSBs from sale in NSW hospital food outlets in 2017 was successfully implemented, with a sample of outlets having nearly 100% compliance. The majority of staff and visitors (80%) supported the removal of SSBs, mostly because they believed it would improve individual and population health.

Social engagement pattern, health behaviors and subjective well-being of older adults: an international perspective using WHO-SAGE survey data.

BACKGROUND: Social engagement forms the basis of social relationships by providing a sense of belonging, social identity, and fulfillment. Previous research demonstrates that social engagement was associated with positive health behaviors among older adults. However, the results have been different across health-related behaviors, and mostly based on data from high-income countries. For example, studies from the US and UK showed that social engagement was protective against smoking, while others found social engagement encouraged more smoking in many Asian cultures. In this study, we aim to examine the association between social engagement and a range of health-related behaviors and subjective well-being among older adults in six low- to middle-income countries. METHODS: Data from the WHO Study on Global Ageing and Adult Health (SAGE Wave 1) were used. A total of 33,338 individuals aged 50 and older in China, Russia, India, Ghana, South Africa, and Mexico were included. Social engagement, tobacco use, alcohol consumption, fruit and vegetable intake, physical activity, sedentary behavior, sleep duration, depression symptoms, self-rated health status, and quality of life were assessed using established self-reported measures. Multiple logistic regression models were used to examine the relationship between social engagement and nine outcome variables, adjusting for socio-demographic characteristics. RESULTS: Lower levels of social engagement were positively related to physical inactivity, prolonged sitting time, unhealthy sleep duration, perceived depression, poor self-rated health, and low quality of life. However, the associations between social engagement and tobacco use, excessive drinking, and insufficient fruit and vegetable intake were mixed across countries. CONCLUSION: This international study found high social engagement as a potential health-promoting factor in some low- to middle-income countries. Although the impacts of social engagement on tobacco and alcohol use and diet were complicated and culture-specific, interventions at both individual and community levels should encourage healthy lifestyles through positive social engagement.

Review of Evaluation Metrics Used in Digital and Traditional Tobacco Control Campaigns.

BACKGROUND: Mass media campaigns for public health are increasingly using digital media platforms, such as web-based advertising and social media; however, there is a lack of evidence on how to best use these digital platforms for public health campaigns. To generate this evidence, appropriate campaign evaluations are needed, but with the proliferation of digital media-related metrics, there is no clear consensus on which evaluation metrics should be used. Public health campaigns are diverse in nature, so to facilitate analysis, this review has selected tobacco control campaigns as the scope of the study. OBJECTIVE: This literature review aimed to examine how tobacco control campaigns that use traditional and digital media platforms have been evaluated. METHODS: Medicine and science databases (Medical Literature Analysis and Retrieval System Online [MEDLINE], EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature [CINAHL], and Scopus), and a marketing case study database (World Advertising Research Center) were searched for articles published between 2013 and 2018. Two authors established the eligibility criteria and reviewed articles for inclusion. Individual campaigns were identified from the articles, and information on campaigns and their evaluations were supplemented with searches on Google, Google Scholar, and social media platforms. Data about campaign evaluations were tabulated and mapped to a conceptual framework. RESULTS: In total, 17 campaigns were included in this review, with evaluations reported on by 51 articles, 17 marketing reports, and 4 grey literature reports. Most campaigns were from English-speaking countries, with behavioral change as the primary objective. In the process evaluations, a wide range of metrics were used to assess the reach of digital campaign activities, making comparison between campaigns difficult. Every campaign in the review, except one, reported some type of engagement impact measure, with website visits being the most commonly reported metric (11 of the 17 campaigns). Other commonly reported evaluation measures identified in this review include engagement on social media, changes in attitudes, and number of people contacting smoking cessation services. Of note, only 7 of the 17 campaigns attempted to measure media platform attribution, for example, by asking participants where they recalled seeing the campaign or using unique website tracking codes for ads on different media platforms. CONCLUSIONS: One of the key findings of this review is the numerous and diverse range of measures and metrics used in tobacco control campaign evaluations. To address this issue, we propose principles to guide the selection of digital media-related metrics for campaign evaluations, and also outline a conceptual framework to provide a coherent organization to the diverse range of metrics. Future research is needed to specifically investigate whether engagement metrics are associated with desired campaign outcomes, to determine whether reporting of engagement metrics is meaningful in campaign evaluations.
