RESUMEN

ISSUE ADDRESSED: Despite increasing interest in citizen science as an approach to engage members of the public in research and decision making about health and wellbeing, there is a lack of practical evidence to guide policy and practice organisations to utilise these approaches. In this study we investigated how and why citizen science came to be incorporated into the work of two policy organisations. METHODS: We offer two in-depth case studies of Australian government organisations which have utilised citizen science in environmental and healthy ageing policy. Interviews with organisational informants and relevant documents were analysed inductively to explore how citizen science came to be adopted, legitimised and supported. RESULTS: Citizen science was utilised to address multiple organisational objectives, including increasing community participation in science; enhancing individuals' wellbeing, learning, and skills, and generating data to support research and policy in a relatively cost-effective manner. In both cases, grant funding was a mechanism to support citizen science, with project delivery facilitated through academic-policy partnerships and led by external academic or community partners. CONCLUSION: Although citizen science is relatively new in policy and practice settings, this study underscores the value of these approaches in realising co-benefits for organisations, academics, and community members. The support and advocacy of senior managers as 'champions', and a willingness to invest in trialling new approaches to address policy problems are necessary ingredients to foster acceptance and legitimacy of citizen science. SO WHAT?: Citizen science initiatives can be strategically utilised by health promotion organisations to enact priorities related to genuine community involvement, support research and innovation and facilitate collaboration and partnerships between academic, policy and community stakeholders.

RESUMEN

OBJECTIVE: To estimate the dose-response associations between non-occupational physical activity and several chronic disease and mortality outcomes in the general adult population. DESIGN: Systematic review and cohort-level dose-response meta-analysis. DATA SOURCES: PubMed, Scopus, Web of Science and reference lists of published studies. ELIGIBILITY CRITERIA: Prospective cohort studies with (1) general population samples >10 000 adults, (2) ≥3 physical activity categories, and (3) risk measures and CIs for all-cause mortality or incident total cardiovascular disease, coronary heart disease, stroke, heart failure, total cancer and site-specific cancers (head and neck, myeloid leukaemia, myeloma, gastric cardia, lung, liver, endometrium, colon, breast, bladder, rectum, oesophagus, prostate, kidney). RESULTS: 196 articles were included, covering 94 cohorts with >30 million participants. The evidence base was largest for all-cause mortality (50 separate results; 163 415 543 person-years, 811 616 events), and incidence of cardiovascular disease (37 results; 28 884 209 person-years, 74 757 events) and cancer (31 results; 35 500 867 person-years, 185 870 events). In general, higher activity levels were associated with lower risk of all outcomes. Differences in risk were greater between 0 and 8.75 marginal metabolic equivalent of task-hours per week (mMET-hours/week) (equivalent to the recommended 150 min/week of moderate-to-vigorous aerobic physical activity), with smaller marginal differences in risk above this level to 17.5 mMET-hours/week, beyond which additional differences were small and uncertain. Associations were stronger for all-cause (relative risk (RR) at 8.75 mMET-hours/week: 0.69, 95% CI 0.65 to 0.73) and cardiovascular disease (RR at 8.75 mMET-hours/week: 0.71, 95% CI 0.66 to 0.77) mortality than for cancer mortality (RR at 8.75 mMET-hours/week: 0.85, 95% CI 0.81 to 0.89). If all insufficiently active individuals had achieved 8.75 mMET-hours/week, 15.7% (95% CI 13.1 to 18.2) of all premature deaths would have been averted. CONCLUSIONS: Inverse non-linear dose-response associations suggest substantial protection against a range of chronic disease outcomes from small increases in non-occupational physical activity in inactive adults. PROSPERO registration number CRD42018095481.

RESUMEN

BACKGROUND: Citizen science (CS) is increasingly being utilised to involve the public in public health research, but little is known about whether and how CS can address the needs of policy and practice stakeholders in health promotion and chronic disease prevention. METHODS: Using a mixed methods approach we conducted an online survey (n = 83) and semi-structured interviews (n = 21) with policy and practice stakeholders across Australia to explore how CS approaches are perceived and applied in chronic disease prevention, how CS aligns with existing approaches to community engagement, and how the uptake of CS can be supported within policy and practice settings. RESULTS: Most participants had heard of CS, and while few had experience of using CS, there was widespread support for this approach, with many seeing it as complementary to other community engagement approaches. CS was seen as providing: (a) a robust framework for engagement; (b) access to rich data; (c) opportunities for more meaningful engagement; and (d) a mutually beneficial approach for stakeholders and community members. However, stakeholders identified a need to weigh benefits against potential risks and challenges including competing organisational priorities, resourcing and expertise, data quality and rigour, governance, and engagement. CONCLUSIONS: To expand the use of CS, stakeholders identified the need for increased awareness, acceptance, and capacity for CS within public health organisations, greater access to supporting tools and technology, and evidence on processes, feasibility and impacts to enhance the visibility and legitimacy of CS approaches.

RESUMEN

Citizen science is rapidly gaining momentum as a means of involving members of the public in research and decision-making in disease prevention and health promotion. However, citizen science projects have predominantly been led by academic researchers and there is limited understanding of how to support the application of citizen science approaches in policy and practice settings. This study aimed to understand the perceptions, motivations and early experiences of applying citizen science approaches in policy and practice settings. Semi-structured interviews were conducted with policy and practice stakeholders who were leading citizen science projects (project partners, n = 7), and their implementation partners (project implementers, n = 11). Participants viewed citizen science as an opportunity to access hard-to-reach data and to enhance engagement with community members to support policy and practice change. Barriers and facilitators of citizen science in policy and practice settings included navigating collaborative relationships, team capacity and resources available to deliver projects, recruitment and engagement of citizen scientists and ethical considerations in the design and implementation of citizen science projects. Findings support the feasibility and wider application of citizen science approaches in health promotion and are being used to inform the development of tools and resources to build capacity in these approaches in policy and practice settings.

RESUMEN

BACKGROUND: Early obesity prevention research interventions in Australia generally expect participants to be able to communicate in English, but do not account for other languages. This study aimed to investigate engagement, satisfaction, retention and behavioural outcomes of linguistically diverse participants from a mainstream early childhood obesity prevention trial. METHODS: Healthy Beginnings is a nurse-led intervention based in Sydney, supporting families with optimal infant feeding and active play via telephone. This secondary analysis assessed participant engagement in the nurse telephone calls (call completions), satisfaction and behavioural outcomes (6- and 12-month survey data) and retention (survey completions), in the first year of life according to participants' language spoken at home (English or other language). RESULTS: Of 1155 mothers, 533 (46%) spoke a language other than English at home. Significantly fewer mothers speaking a language other than English completed the 6-month survey (79%) compared to those speaking English (84%), yet mothers speaking a language other than English who completed the program were more satisfied with the program overall. Significantly fewer mothers speaking a language other than English completed the final four nurse calls (of six) (56%-65%) compared to those speaking English (70%-80%). Adjusted odds ratios showed selected behavioural outcomes were significantly more positive for participants speaking English at home. CONCLUSIONS: Healthy Beginnings trial participants who spoke a language other than English at home had less favourable engagement, retention and behavioural outcomes compared to those who spoke English. So what? Early obesity prevention interventions should consider cultural adaptations to improve engagement and effectiveness among culturally and linguistically diverse families.

RESUMEN

INTRODUCTION: Healthy Beginnings is an established nurse-led early childhood obesity prevention program that promotes healthy infant feeding practices and active play in the early years of life. To improve engagement with culturally and linguistically diverse populations, the Healthy Beginnings program delivered by telephone was culturally adapted and implemented with Arabic- and Chinese-speaking mothers in Sydney, Australia. The cultural adaptation process has been published separately. In this article, we aimed to evaluate the feasibility of the culturally adapted program. METHODS: In 2018-2019, the culturally adapted Healthy Beginnings program was implemented with Arabic- and Chinese-speaking women recruited from antenatal clinics in Sydney. At four staged timepoints (from third trimester until 6 months of age), mothers were sent culturally adapted health promotion booklets and text messages and offered four support calls from bi-cultural child and family health nurses in Arabic and Chinese. A mixed methods evaluation included a) baseline and 6-month telephone surveys, followed by b) semi-structured follow-up interviews with a subset of participating mothers and program delivery staff. Main outcomes of this feasibility study were reach (recruitment and retention), intervention dose delivered (number of nurse support calls completed) and acceptability (appropriateness based on cognitive and emotional responses). RESULTS: At recruitment, 176 mothers were eligible and consented to participate. Of 163 mothers who completed the baseline survey, 95% completed the program (n = 8 withdrew) and 83% completed the 6-month survey (n = 70 Arabic- and n = 65 Chinese-speaking mothers). Most mothers (n = 127, 78%) completed at least one nurse support call. The qualitative analysis of follow-up interviews with 42 mothers (22 Arabic- and 20 Chinese-speaking mothers) and 10 program delivery staff highlighted the perceived value of the program and the positive role of bi-cultural nurses and in-language resources. Mothers who completed more nurse support calls generally expressed greater acceptability. CONCLUSIONS: The culturally adapted Healthy Beginnings program was feasible to deliver and acceptable to Arabic- and Chinese-speaking mothers. Our results highlight the importance of in-language resources and individualised bi-cultural nurse support by telephone for supporting culturally and linguistically diverse migrant families with infant feeding and active play. These findings support the potential for program refinements and progression to an effectiveness trial.

RESUMEN

BACKGROUND: Behavioural interventions for the early prevention of childhood obesity mostly focus on English-speaking populations in high-income countries. Cultural adaptation is an emerging strategy for implementing evidence-based interventions among different populations and regions. This paper describes the initial process of culturally adapting Healthy Beginnings, an evidence-based early childhood obesity prevention program, for Arabic and Chinese speaking migrant mothers and infants in Sydney, Australia. METHODS: The cultural adaptation process followed the Stages of Cultural Adaptation theoretical model and is reported using the Framework for Reporting Adaptations and Modifications-Enhanced. We first established the adaptation rationale, then considered program underpinnings and the core components for effectiveness. To inform adaptations, we reviewed the scientific literature and engaged stakeholders. Consultations included focus groups with 24 Arabic and 22 Chinese speaking migrant mothers and interviews with 20 health professionals. With input from project partners, bi-cultural staff and community organisations, findings informed cultural adaptations to the content and delivery features of the Healthy Beginnings program. RESULTS: Program structure and delivery mode were retained to preserve fidelity (i.e. staged nurse calls with key program messages addressing modifiable obesity-related behaviours: infant feeding, active play, sedentary behaviours and sleep). Qualitative analysis of focus group and interview data resulted in descriptive themes concerning cultural practices and beliefs related to infant obesity-related behaviours and perceptions of child weight among Arabic and Chinese speaking mothers. Based on the literature and local study findings, cultural adaptations were made to recruitment approaches, staffing (bi-cultural nurses and project staff) and program content (modified call scripts and culturally adapted written health promotion materials). CONCLUSIONS: This cultural adaptation of Healthy Beginnings followed an established process model and resulted in a program with enhanced relevance and accessibility among Arabic and Chinese speaking migrant mothers. This work will inform the future cultural adaptation stages: testing, refining, and trialling the culturally adapted Healthy Beginnings program to assess acceptability, feasibility and effectiveness.

RESUMEN

BACKGROUND: The importance of engaging stakeholders in the research process is well recognised. Whilst engagement is important, guidelines and practices vary for how stakeholders should be involved in research and how to facilitate effective collaborative relationships. METHODS: This study aimed to explore the perspectives and experiences of stakeholders involved in the policy and practice area of outdoor space and non-communicable disease prevention. Stakeholders interviewed included academics, practitioners, policy-makers, knowledge brokers and a funder. RESULTS: The findings suggest that stakeholders had positive experiences when engaged meaningfully in the research process, where research projects were carefully planned and managed with attention to context and culture, and where the research team was effective, respectful and communicative. These factors help to facilitate the translation of research into policy and practice. However, multiple challenges of collaborative research were identified which related to structural and systemic challenges, building and maintaining relationships, use and collection of data and information, cultural perceptions of research and research generation, and getting evidence into action. Participants felt that changing the funding system, exploring more collaborative research methodologies, improved research translation, and more effective collaborative relationships at all stages of the research process could address some of these challenges. CONCLUSIONS: The findings highlight that, whilst stakeholder engagement in research was considered important, structural, cultural and individual practices impacted how this worked in practice. Identifying and testing solutions to address these challenges could improve synergies between research, policy, and practice and lead to the production of impactful research that reduces wastage of public funding, improves implementation of findings and ultimately improves public health outcomes.

RESUMEN

BACKGROUND: The global prevalence of childhood and adolescent obesity is high. Lifestyle changes towards a healthy diet, increased physical activity and reduced sedentary activities are recommended to prevent and treat obesity. Evidence suggests that changing these health behaviours can benefit cognitive function and school achievement in children and adolescents in general. There are various theoretical mechanisms that suggest that children and adolescents with excessive body fat may benefit particularly from these interventions. OBJECTIVES: To assess whether lifestyle interventions (in the areas of diet, physical activity, sedentary behaviour and behavioural therapy) improve school achievement, cognitive function (e.g. executive functions) and/or future success in children and adolescents with obesity or overweight, compared with standard care, waiting-list control, no treatment, or an attention placebo control group. SEARCH METHODS: In February 2017, we searched CENTRAL, MEDLINE and 15 other databases. We also searched two trials registries, reference lists, and handsearched one journal from inception. We also contacted researchers in the field to obtain unpublished data. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials (RCTs) of behavioural interventions for weight management in children and adolescents with obesity or overweight. We excluded studies in children and adolescents with medical conditions known to affect weight status, school achievement and cognitive function. We also excluded self- and parent-reported outcomes. DATA COLLECTION AND ANALYSIS: Four review authors independently selected studies for inclusion. Two review authors extracted data, assessed quality and risks of bias, and evaluated the quality of the evidence using the GRADE approach. We contacted study authors to obtain additional information. We used standard methodological procedures expected by Cochrane. Where the same outcome was assessed across different intervention types, we reported standardised effect sizes for findings from single-study and multiple-study analyses to allow comparison of intervention effects across intervention types. To ease interpretation of the effect size, we also reported the mean difference of effect sizes for single-study outcomes. MAIN RESULTS: We included 18 studies (59 records) of 2384 children and adolescents with obesity or overweight. Eight studies delivered physical activity interventions, seven studies combined physical activity programmes with healthy lifestyle education, and three studies delivered dietary interventions. We included five RCTs and 13 cluster-RCTs. The studies took place in 10 different countries. Two were carried out in children attending preschool, 11 were conducted in primary/elementary school-aged children, four studies were aimed at adolescents attending secondary/high school and one study included primary/elementary and secondary/high school-aged children. The number of studies included for each outcome was low, with up to only three studies per outcome. The quality of evidence ranged from high to very low and 17 studies had a high risk of bias for at least one item. None of the studies reported data on additional educational support needs and adverse events.Compared to standard practice, analyses of physical activity-only interventions suggested high-quality evidence for improved mean cognitive executive function scores. The mean difference (MD) was 5.00 scale points higher in an after-school exercise group compared to standard practice (95% confidence interval (CI) 0.68 to 9.32; scale mean 100, standard deviation 15; 116 children, 1 study). There was no statistically significant beneficial effect in favour of the intervention for mathematics, reading, or inhibition control. The standardised mean difference (SMD) for mathematics was 0.49 (95% CI -0.04 to 1.01; 2 studies, 255 children, moderate-quality evidence) and for reading was 0.10 (95% CI -0.30 to 0.49; 2 studies, 308 children, moderate-quality evidence). The MD for inhibition control was -1.55 scale points (95% CI -5.85 to 2.75; scale range 0 to 100; SMD -0.15, 95% CI -0.58 to 0.28; 1 study, 84 children, very low-quality evidence). No data were available for average achievement across subjects taught at school.There was no evidence of a beneficial effect of physical activity interventions combined with healthy lifestyle education on average achievement across subjects taught at school, mathematics achievement, reading achievement or inhibition control. The MD for average achievement across subjects taught at school was 6.37 points lower in the intervention group compared to standard practice (95% CI -36.83 to 24.09; scale mean 500, scale SD 70; SMD -0.18, 95% CI -0.93 to 0.58; 1 study, 31 children, low-quality evidence). The effect estimate for mathematics achievement was SMD 0.02 (95% CI -0.19 to 0.22; 3 studies, 384 children, very low-quality evidence), for reading achievement SMD 0.00 (95% CI -0.24 to 0.24; 2 studies, 284 children, low-quality evidence), and for inhibition control SMD -0.67 (95% CI -1.50 to 0.16; 2 studies, 110 children, very low-quality evidence). No data were available for the effect of combined physical activity and healthy lifestyle education on cognitive executive functions.There was a moderate difference in the average achievement across subjects taught at school favouring interventions targeting the improvement of the school food environment compared to standard practice in adolescents with obesity (SMD 0.46, 95% CI 0.25 to 0.66; 2 studies, 382 adolescents, low-quality evidence), but not with overweight. Replacing packed school lunch with a nutrient-rich diet in addition to nutrition education did not improve mathematics (MD -2.18, 95% CI -5.83 to 1.47; scale range 0 to 69; SMD -0.26, 95% CI -0.72 to 0.20; 1 study, 76 children, low-quality evidence) and reading achievement (MD 1.17, 95% CI -4.40 to 6.73; scale range 0 to 108; SMD 0.13, 95% CI -0.35 to 0.61; 1 study, 67 children, low-quality evidence). AUTHORS' CONCLUSIONS: Despite the large number of childhood and adolescent obesity treatment trials, we were only able to partially assess the impact of obesity treatment interventions on school achievement and cognitive abilities. School and community-based physical activity interventions as part of an obesity prevention or treatment programme can benefit executive functions of children with obesity or overweight specifically. Similarly, school-based dietary interventions may benefit general school achievement in children with obesity. These findings might assist health and education practitioners to make decisions related to promoting physical activity and healthy eating in schools. Future obesity treatment and prevention studies in clinical, school and community settings should consider assessing academic and cognitive as well as physical outcomes.

RESUMEN

UNLABELLED: Adolescent girls have been targeted as a priority group for promoting physical activity levels however it is unclear how this can be achieved. There is some evidence to suggest that social support could impact the physical activity levels of adolescent girls, although the relationship is complex and not well understood. We aimed to systematically review and meta-analyse the relationship between social support and physical activity in adolescent girls, exploring how different types and providers of social support might influence the relationship. Articles were identified through a systematic search of the literature using 14 electronic databases, personal resources, grey literature, and reference lists of included studies and previous reviews. Search terms representing social support, physical activity and adolescent girls were identified and used in various combinations to form a search strategy which was adapted for different databases. Cross-sectional or longitudinal articles published in English that reported an association between social support and physical activity in adolescent girls between the ages of 10 to 19 years were included. Studies that focused only on clinical or overweight populations were excluded. Data extraction was carried out by one reviewer using an electronic extraction form. A random 25 % of included articles were selected for data extraction by a second reviewer to check fidelity. Risk of bias was assessed using a custom tool informed by the Critical Appraisal Skills Programme Cohort Study Checklist in conjunction with data extraction. Cross-sectional results were meta-analysed and longitudinal results were presented narratively. Small but significant associations between all available providers of total social support (except teachers) and physical activity were found (r = .14-.24). Small but significant associations were also identified for emotional, instrumental and modelling support for some providers of support (r = .10-.21). Longitudinal research supported the cross-sectional analyses. Many of the meta-analysis results suggested high heterogeneity and there was some evidence of publication bias, therefore, the meta-analysis results should be interpreted with caution. In conclusion, the meta-analysis results suggest that social support is not a strong predictor of physical activity in adolescent girls though parents and friends may have a role in enhancing PA.

RESUMEN

Policymakers and practitioners in health promotion (e.g. those working for local, state or federal government organisations or community and non-government organisations with a focus on health and wellbeing) are increasingly interested in citizen science as a means of involving the public in research and decision making. The potential benefits of citizen science approaches in health promotion include increased research capacity, incorporation of community perspectives on problems and solutions, and improved public awareness and acceptance of actions to improve health. However, health promotion practitioners and policymakers report having limited familiarity and experience with citizen science and a desire to build their capacity in these approaches. The Citizen Science in Prevention (CSP) project aims to build capacity for citizen science in health promotion by: 1) supporting the development and implementation of citizen science projects by policymakers and practitioners, 2) establishing a network of health promotion stakeholders with familiarity and interest in citizen science approaches, and 3) co-designing resources to support the use of citizen science in policy and practice contexts. A comprehensive mixed methods evaluation will establish the reach, satisfaction, and impacts that can be attributed to the capacity building intervention. This paper describes the first known initiative to build capacity in the application of citizen science approaches in health promotion and we hope that this work will assist others in the development and implementation of capacity building activities for citizen science in health promotion and beyond.


Citizen science, the active involvement of members of the public in undertaking research, is gaining attention as a means of involving the public in research and decision making in health promotion. However, despite increasing interest in citizen science, policymakers and practitioners in health promotion (e.g. those working for local, state or federal government organisations or community and non-government organisations with a focus on health and wellbeing), lack the knowledge, skills and confidence to apply these approaches within their work. Knowledge mobilisation is a process designed to ensure research is useful for society, underpinned by researchers and non-academic partners working together to ensure that the knowledge produced is relevant and useful to those responsible for making decisions in practice. Within this paper we describe how we have used a knowledge mobilisation approach to work in partnership with health promotion agencies to develop, implement and evaluate a suite of activities aimed at building capacity in the use of citizen science approaches in health promotion.

RESUMEN

Background: Citizen science approaches, which involve members of the public as active collaborators in scientific research, are increasingly being recognized for their potential benefits in chronic disease prevention. However, understanding the potential applicability, feasibility and impacts of these approaches is necessary if they are to be more widely used. This study aimed to synthesize research that has applied and evaluated citizen science approaches in chronic disease prevention and identify key questions, gaps, and opportunities to inform future work in this field. Methods: We searched six databases (Scopus, Medline, Embase, PsycInfo, PubMed, and CINAHL) in January 2022 to identify articles on the use of citizen science in prevention. We extracted and synthesized data on key characteristics of citizen science projects, including topics, aims and level of involvement of citizen scientists, as well as methods and findings of evaluations of these projects. Results: Eighty-one articles reported on citizen science across a variety of health issues, predominantly physical activity and/or nutrition. Projects primarily aimed to identify problems from the perspective of community members; generate and prioritize solutions; develop, test or evaluate interventions; or build community capacity. Most projects were small-scale, and few were co-produced with policy or practice stakeholders. While around half of projects included an evaluation component, overall, there was a lack of robust, in-depth evaluations of the processes and impacts of citizen science projects. Conclusions: Citizen science approaches are increasingly being used in chronic disease prevention to identify and prioritize community-focused solutions, mobilize support and advocacy, and empower communities to take action to support their health and wellbeing. However, to realize the potential of this approach more attention needs to be paid to demonstrating the feasibility of using citizen science approaches at scale, and to rigorous evaluation of impacts from using these approaches for the diverse stakeholders involved.

RESUMEN

Interventions for obesity prevention can effectively reduce obesity-related behaviors in young children. Understanding how to leverage and adapt evidence-based interventions is needed to improve reach among culturally and linguistically diverse families. This systematic review aimed to synthesize the approaches and outcomes of culturally adapted early childhood obesity-related behavioral prevention interventions. Multiple electronic databases were systematically searched in March 2021. All study designs were included if they reported cultural adaptations of an intervention targeting at least one obesity-related behavior (infant feeding, nutrition, physical activity, and/or sleep) among children aged 0-5 years. Studies that only conducted language translations or that developed new interventions were excluded. Two authors independently conducted critical appraisals using the Mixed Method Appraisal Tool. Findings were synthesized narratively, based on the Stages of Cultural Adaptation theoretical model and the Framework for Reporting Adaptations and Modifications-Enhanced. Twelve interventions met the inclusion criteria, with varied study designs. Few reported all aspects of cultural adaptation processes, and the cultural adaptation strategies documented varied. The results suggest that cultural adaptation of obesity-related behavioral prevention interventions targeting young children increases acceptability among target cultural groups, yet effectiveness is inconclusive due to a lack of trials. More detailed reporting of cultural adaptation processes and further effectiveness trials are needed to evaluate future work.

RESUMEN

Body dissatisfaction is among the most common mental health challenges experienced by women and has been identified as a risk factor for disordered eating. Research has found that exposure to social media images depicting thin, muscular bodies, often dubbed 'fitspiration', may contribute to body dissatisfaction. Image-centred social media platforms, such as Instagram, have rising popularity among adolescents and young adults. However, little is known about the content of images produced by different fitness-related sources, such as those from fitness brands compared with individual users, and how fitness content on social media is evolving over time. This study sought to determine whether Instagram content varied between female fitness influencers and brands and how this content changed between 2019 and 2021. A longitudinal content analysis was conducted on a sample of 400 Instagram images using a coding scheme developed specifically for this project. The scheme coded images for fit ideal body depiction, fitness focus, objectification, and sexualisation. Chi-square tests indicated that female fitness influencer content was more sexualised and portrayed more of the fit ideal, while fitness brands produced more Instagram content with a fitness focus. There were no significant overall longitudinal changes for any of the four key variables. However, when looking at longitudinal changes by account type, fitness-focused influencer content increased while fitness-focused brand content decreased over time. These findings highlight discernible differences in content produced by different Instagram account types. It points future research towards the consideration of potential moderating factors, such as account type, when exploring the impact of social media images on body image and mental health.

RESUMEN

Background: The lack of a comprehensive understanding of the role of mass media in perpetuating weight stigma hinders policy formulation. We reviewed the influence of mass media on weight stigmatisation and the effectiveness of media-based interventions designed to prevent or reduce stigma. Methods: We conducted a systematic review across seven databases from inception to December 2021. Included studies assessed exposure to or impact of weight stigma in mass media or examined interventions to reduce stigma through media in populations 12+ years. We synthesised data narratively, categorising studies based on similarity in focus to produce a set of integrated findings. The systematic review is registered in PROSPERO (No. CRD42020176306). Findings: One-hundred-and-thirteen records were eligible for inclusion from 2402 identified; 95 examined the prevalence of stigmatising content in mass media and its impact on stigma. Weight stigma was prevalent across media types, with the dominant discourse viewing overweight and obesity as an individual responsibility and overlooking systemic factors. Exposure to stigmatising content was found to negatively influence attitudes towards people with overweight or obesity. Few studies considered methods of reducing stigma in the media, with only two testing media-based interventions; their results were promising but limited. Interpretation: Weight stigma in media content is prevalent and harmful, but there is little guidance on reducing it. Future research focus needs to shift from assessing prevalence and impacts to weight stigma interventions. Funding: None.

RESUMEN

Importance: Depression is the leading cause of mental health-related disease burden and may be reduced by physical activity, but the dose-response relationship between activity and depression is uncertain. Objective: To systematically review and meta-analyze the dose-response association between physical activity and incident depression from published prospective studies of adults. Data Sources: PubMed, SCOPUS, Web of Science, PsycINFO, and the reference lists of systematic reviews retrieved by a systematic search up to December 11, 2020, with no language limits. The date of the search was November 12, 2020. Study Selection: We included prospective cohort studies reporting physical activity at 3 or more exposure levels and risk estimates for depression with 3000 or more adults and 3 years or longer of follow-up. Data Extraction and Synthesis: Data extraction was completed independently by 2 extractors and cross-checked for errors. A 2-stage random-effects dose-response meta-analysis was used to synthesize data. Study-specific associations were estimated using generalized least-squares regression and the pooled association was estimated by combining the study-specific coefficients using restricted maximum likelihood. Main Outcomes and Measures: The outcome of interest was depression, including (1) presence of major depressive disorder indicated by self-report of physician diagnosis, registry data, or diagnostic interviews and (2) elevated depressive symptoms established using validated cutoffs for a depressive screening instrument. Results: Fifteen studies comprising 191 130 participants and 2 110 588 person-years were included. An inverse curvilinear dose-response association between physical activity and depression was observed, with steeper association gradients at lower activity volumes; heterogeneity was large and significant (I2 = 74%; P < .001). Relative to adults not reporting any activity, those accumulating half the recommended volume of physical activity (4.4 marginal metabolic equivalent task hours per week [mMET-h/wk]) had 18% (95% CI, 13%-23%) lower risk of depression. Adults accumulating the recommended volume of 8.8 mMET hours per week had 25% (95% CI, 18%-32%) lower risk with diminishing potential benefits and higher uncertainty observed beyond that exposure level. There were diminishing additional potential benefits and greater uncertainty at higher volumes of physical activity. Based on an estimate of exposure prevalences among included cohorts, if less active adults had achieved the current physical activity recommendations, 11.5% (95% CI, 7.7%-15.4%) of depression cases could have been prevented. Conclusions and Relevance: This systematic review and meta-analysis of associations between physical activity and depression suggests significant mental health benefits from being physically active, even at levels below the public health recommendations. Health practitioners should therefore encourage any increase in physical activity to improve mental health.

RESUMEN

There is evidence for the physical health benefits of high intensity interval exercise (HIIE), but its public health potential has been challenged. It is purported that compared with moderate-intensity continuous exercise (MICE) the high intensity nature of HIIE may lead to negative affective responses. This systematic review (PROSPERO CRD42017058203) addressed this proposition and synthesised research that compares affective responses to HIIE with MICE and vigorous intensity continuous exercise (VICE), during-, end-, and post-exercise. Searches were conducted on five databases, and findings from 33 studies were meta-analysed using random effects models or narratively synthesised. A meta-analysis of affect showed a significant effect in favour of MICE vs HIIE at the lowest point, during and post-exercise, but not at end, and the narrative synthesis supported this for other affective outcomes. Differences on affect between VICE vs HIIE were limited. Pooled data showed arousal levels were consistently higher during HIIE. For enjoyment there was a significant effect in favour of HIIE vs MICE, no difference for HIIE vs VICE at post-exercise, and mixed findings for during-exercise. Although the findings are clouded by methodological issues they indicate that compared to MICE, HIIE is experienced less positively but post-exercise is reported to be more enjoyable.

RESUMEN

Optimal feeding practices can establish lifelong, transgenerational and global health benefits. Migration and cultural factors impact infant feeding practices and the support mothers receive for optimal infant feeding. This qualitative study explored support for infant feeding among Arabic and Chinese speaking migrant mothers in Australia. Semi-structured focus groups were conducted in language with 24 Arabic and 22 Chinese-Mandarin speaking migrant mothers with children under five years of age. Individual interviews were conducted in English with 20 health professionals working with Arabic or Chinese speaking migrant families. Data were thematically analysed using the framework method. Traditional family networks and trusted bi-cultural doctors were influential infant feeding supports for mothers. Health professionals perceived maternal and child health services to be poorly understood, and some mothers who accessed services felt they were not always culturally sensitive. Mothers sought additional information and support through online sources and peers. Both mothers and health professionals recognised the challenges of managing conflicting infant feeding advice and seeking best-practice support. The findings of this study highlight opportunities for health professionals to better support migrant mothers' infant feeding practices, for example through engaging families and working with doctors. There is a need for greater cultural sensitivity within maternal and child health services and culturally relevant programs to support healthy infant feeding practices among migrant communities.

RESUMEN

The Scottish Government launched a tobacco control strategy in 2013 with the ambition of making Scotland tobacco smoke-free by 2034. However, 17% of the adult population in Scotland smoke cigarettes. This study aimed to provide insight into why policies are successful or not and provide suggestions for future policy actions. Individual interviews with ten tobacco control experts were conducted and the results were analyzed using thematic analysis. Key successes included strong political leadership, mass media campaigns, legislation to address availability and marketing of cigarettes and tobacco products, and legislation to reduce second-hand smoke exposure. Challenges included implementing policy actions, monitoring and evaluation of tobacco control actions, addressing health inequalities in smoking prevalence, and external factors that influenced the success of policy actions. Key suggestions put forward for future policy actions included addressing the price and availability of tobacco products, maintaining strong political leadership on tobacco control, building on the success of the 'Take it Right Outside' mass media campaign with further mass media campaigns to tackle other aspects of tobacco control, and developing and testing methods of addressing inequalities in cigarette smoking prevalence. The findings of this study can inform future tobacco control policy in Scotland and have relevance for tobacco control policies in other countries.
