AbstractBackgroundRemission of type 2 diabetes through weight loss is possible in a high proportion of persons with a recent diagnosis, but a major challenge is achieving sufficient weight loss.ObjectivesIn the first study of this type in the Caribbean, we investigated factors associated with successful weight loss in adults in a diabetes remission intervention. We hypothesized that differences in social support may have influenced differences in weight loss achieved by participants in the Barbados Diabetes Reversal Study (BDRS).MethodsA comparative case study was conducted. Quantitative data for the primary outcome measure of weight reduction (the participants’ baseline and 8-month weights) were assessed to identify the 6 participants with the highest and 6 participants with the lowest weight loss. The 8-week (low-calorie diet phase) and 8-month (weight maintenance phase) interview transcripts for each participant were then analysed via qualitative thematic analysis to explore factors related to social support.ResultsInformal and formal support were identified for both categories of participants. Cases were similar with respect to their sources of support however dissimilarities were found in (1) the depth of support received; (2) access to supportive environments and (3) diversity of social supportive networks. Participants in the top weight loss group reported consistency in the levels of support received over the low-calorie diet and weight maintenance phases of the study while the converse was true for those of the bottom weight loss group.ConclusionStudy findings suggest that individuals aiming at type 2 diabetes remission benefit from strong social support networks. These networks provide tangible assistance and facilitate the sharing and discussion of strategies for weight reduction. Future studies should facilitate in-depth understanding of how formal and informal supportive networks can aid sustained dietary diabetes remission and long-term weight maintenance.

CONTEXT: COVID-19 mitigation measures including border lockdowns, social distancing, de-urbanization and restricted movements have been enforced to reduce the risks of COVID-19 arriving and spreading across PICs. To reduce the negative impacts of COVID-19 mitigation measures, governments have put in place a number of interventions to sustain food and income security. Both mitigation measures and interventions have had a number of impacts on agricultural production, food systems and dietary diversity at the national and household levels. OBJECTIVE: Our paper conducted an exploratory analysis of immediate impacts of both COVID-19 mitigation measures and interventions on households and communities in PICs. Our aim is to better understand the implications of COVID-19 for PICs and identify knowledge gaps requiring further research and policy attention. METHODS: to understand the impacts of COVID-19 mitigation measures and interventions on food systems and diets in PICs, 13 communities were studied in Fiji and Solomon Islands in July-August 2020. In these communities, 46 focus group discussions were carried out and 425 households were interviewed. Insights were also derived from a series of online discussion sessions with local experts of Pacific Island food and agricultural systems in August and September 2020. To complement these discussions, an online search was conducted for available literature. RESULTS AND CONCLUSIONS: Identified impacts include: 1) Reduced agricultural production, food availability and incomes due to a decline in local markets and loss of access to international markets; 2) Increased social conflict such as land disputes, theft of high-value crops and livestock, and environmental degradation resulting from urban-rural migration; 3) Reduced availability of seedlings, planting materials, equipment and labour in urban areas; 4) Reinvigoration of traditional food systems and local food production; and 5) Re-emergence of cultural safety networks and values, such as barter systems. Households in rural and urban communities appear to have responded positively to COVID-19 by increasing food production from home gardens, particularly root crops, vegetables and fruits. However, the limited diversity of agricultural production and decreased household incomes are reducing the already low dietary diversity score that existed pre-COVID-19 for households. SIGNIFICANCE: These findings have a number of implications for future policy and practice. Future interventions would benefit from being more inclusive of diverse partners, focusing on strengthening cultural and communal values, and taking a systemic and long-term perspective. COVID-19 has provided an opportunity to strengthen traditional food systems and re-evaluate, re-imagine and re-localize agricultural production strategies and approaches in PICs.

Purpose: to examine adolescent experiences and perspectives of the GoActive intervention (ISRCTN31583496) using mixed methods process evaluation to determine satisfaction with intervention components and interpret adolescents' experiences of the intervention process in order to provide insights for future intervention design. Methods: Participants (n = 1542; 13.2 ± �
0.4 years, mean ± SD) provided questionnaire data at baseline (shyness, activity level) and post-intervention (intervention acceptability, satisfaction with components). Between-group differences (boys vs. girls and shy/inactive vs. others) were tested with linear regression models, accounting for school clustering. Data from 16 individual interviews (shy/inactive) and 11 focus groups with 48 participants (mean = 4; range 2-7) were thematically coded. Qualitative and quantitative data were merged in an integrative mixed methods convergence matrix, which denoted convergence and dissonance across datasets. Results: Effect sizes for quantitative results were small and may not represent substantial between-group differences. Boys (vs. girls) preferred class-based sessions (β = 0.2, 95% confidence interval (CI): 0.1-0.3); qualitative data suggested that this was because boys preferred competition, which was supported quantitatively (β = 0.2, 95%CI: 0.1-0.3). Shy/inactive students did not enjoy the competition (β = -0.3, 95%CI: -0.5 to -0.1). Boys enjoyed trying new activities more (β = 0.1, 95%CI: 0.1-0.2); qualitative data indicated a desire to try new activities across all subgroups but identified barriers to choosing unfamiliar activities with self-imposed choice restriction leading to boredom. Qualitative data highlighted critique of mentorship; adolescents liked the idea, but older mentors did not meet expectations. Conclusion: We interpreted adolescent perspectives of intervention components and implementation to provide insights into future complex interventions aimed at increasing young people's physical activity in school-based settings. The intervention component mentorship was liked in principle, but implementation issues undesirably impacted satisfaction; competition was disliked by girls and shy/inactive students. The results highlight the importance of considering gender differences in preference of competition and extensive mentorship training.

Small Island Developing States (SIDS) have high and increasing rates of diet-related diseases. This situation is associated with a loss of food sovereignty and an increasing reliance on nutritionally poor food imports. A policy goal, therefore, is to improve local diets through improved local production of nutritious foods. Our aim in this study was to develop methods and collect preliminary data on the relationships between where people source their food, their socio-demographic characteristics and dietary quality in Fiji and Saint Vincent and the Grenadines (SVG) in order to inform further work towards this policy goal. We developed a toolkit of methods to collect individual-level data, including measures of dietary intake, food sources, socio-demographic and health indicators. Individuals aged ≥15 years were eligible to participate. From purposively sampled urban and rural areas, we recruited 186 individuals from 95 households in Fiji, and 147 individuals from 86 households in SVG. Descriptive statistics and multiple linear regression were used to investigate associations. The mean dietary diversity score, out of 10, was 3.7 (SD1.4) in Fiji and 3.8 (SD1.5) in SVG. In both settings, purchasing was the most common way of sourcing food. However, 68% (Fiji) and 45% (SVG) of participants regularly (>weekly) consumed their own produce, and 5% (Fiji) and 33% (SVG) regularly consumed borrowed/exchanged/bartered food. In regression models, independent positive associations with dietary diversity (DD) were: borrowing/exchanging/bartering food (β = 0.73 (0.21, 1.25)); age (0.01 (0.00, 0.03)); and greater than primary education (0.44 (0.06, 0.82)). DD was negatively associated with small shop purchasing (-0.52 (95% CIs -0.91, -0.12)) and rural residence (-0.46 (-0.92, 0.00)). The findings highlight associations between dietary diversity and food sources and indicate avenues for further research to inform policy actions aimed at improving local food production and diet.

To effectively tackle population health challenges, we must address the fundamental determinants of behaviour and health. Among other things, this will entail devoting more attention to the evaluation of upstream intervention strategies. However, merely increasing the supply of such studies is not enough. The pivotal link between research and policy or practice should be the cumulation of insight from multiple studies. If conventional evidence synthesis can be thought of as analogous to building a wall, then we can increase the supply of bricks (the number of studies), their similarity (statistical commensurability) or the strength of the mortar (the statistical methods for holding them together). However, many contemporary public health challenges seem akin to herding sheep in mountainous terrain, where ordinary walls are of limited use and a more flexible way of combining dissimilar stones (pieces of evidence) may be required. This would entail shifting towards generalising the functions of interventions, rather than their effects; towards inference to the best explanation, rather than relying on binary hypothesis-testing; and towards embracing divergent findings, to be resolved by testing theories across a cumulated body of work. In this way we might channel a spirit of pragmatic pluralism into making sense of complex sets of evidence, robust enough to support more plausible causal inference to guide action, while accepting and adapting to the reality of the public health landscape rather than wishing it were otherwise. The traditional art of dry stone walling can serve as a metaphor for the more holistic sense-making we propose.

School-based multi-component physical activity (PA) promotion is advocated; however, research has indicated that a multi-component approach may not always be effective at increasing adolescent PA. Evaluation of the GoActive 12-week multi-component school-based intervention showed no effect on adolescent PA. A mixed-methods process evaluation was embedded to facilitate greater understanding of the results, to elicit subgroup perceptions, and to provide insight into contextual factors influencing intervention implementation. This paper presents the reach, recruitment, dose, and fidelity of GoActive, and identifies challenges to implementation. The process evaluation employed questionnaires (1543 Year 9s), individual interviews (16 Year 9s; 7 facilitators; 9 contact teachers), focus groups (48 Year 9s; 58 mentors), alongside GoActive website analytics and researcher observations. GoActive sessions reached 39.4% of Year 9s. Intervention satisfaction was relatively high for mentors (87.3%) and facilitators (85.7%), but lower for Year 9s (59.5%) and teachers (50%). Intervention fidelity was mixed within and between schools. Mentorship was the most implemented component. Factors potentially contributing to low implementation included ambiguity of the roles subgroups played within intervention delivery, Year 9 engagement, institutional support, and further school-level constraints. Multiple challenges and varying contextual considerations hindered the implementation of GoActive in multiple school sites. Methods to overcome contextual challenges to implementation warrant in-depth consideration and innovative approaches.

Background: Cancer is a leading cause of premature death in women worldwide, and is associated with socio-economic disadvantage. Yet many interventions designed to reduce risk and improve health fail to reach the most marginalised with the greatest needs. Our study focused on socially marginalised women at two women's centres that provide support and training to women in the judicial system or who have experienced domestic abuse. Methods: This qualitative study was framed within a sociological rather than behavioural perspective involving thirty participants in individual interviews and focus groups. It sought to understand perceptions of, and vulnerability to, cancer; decision making (including screening); cancer symptom awareness and views on health promoting activities within the context of the women's social circumstances. Findings: Women's experiences of social adversity profoundly shaped their practices, aspirations and attitudes towards risk, health and healthcare. We found that behaviours, such as unhealthy eating and smoking need to be understood in the context of inherently risky lives. They were a coping mechanism whilst living in extreme adverse circumstances, navigating complex everyday lives and structural failings. Long term experiences of neglect, harm and violence, often by people they should be able to trust, led to low self-esteem and influenced their perceptions of risk and self-care. This was reinforced by negative experiences of navigating state services and a lack of control and agency over their own lives. Conclusion: Women in this study were at high risk of cancer, but it would be better to understand these risk factors as markers of distress and duress. Without appreciating the wider determinants of health and systemic disadvantage of marginalised groups, and addressing these with a structural rather than an individual response, we risk increasing cancer inequities by failing those who are in the greatest need.

BACKGROUND: Innovative approaches are required to move beyond individual approaches to behaviour change and develop more appropriate insights for the complex challenge of increasing population levels of activity. Recent research has drawn on social practice theory to describe the recursive and relational character of active living but to date most evidence is limited to small-scale qualitative research studies. To 'upscale' insights from individual contexts, we pooled data from five qualitative studies and used machine learning software to explore gendered patterns in the context of active travel. METHODS: We drew on 280 transcripts from five research projects conducted in the UK, including studies of a range of populations, travel modes and settings, to conduct unsupervised 'topic modelling analysis'. Text analytics software, Leximancer, was used in the first phase of the analysis to produce inter-topic distance maps to illustrate inter-related 'concepts'. The outputs from this first phase guided a second researcher-led interpretive analysis of text excerpts to infer meaning from the computer-generated outputs. RESULTS: Guided by social practice theory, we identified 'interrelated' and 'relating' practices across the pooled datasets. For this study we particularly focused on respondents' commutes, travelling to and from work, and on differentiated experiences by gender. Women largely described their commute as multifunctional journeys that included the school run or shopping, whereas men described relatively linear journeys from a to B but highlighted 'relating' practices resulting from or due to their choice of commute mode or journey such as showering or relaxing. Secondly, we identify a difference in discourses about practices across the included datasets. Women spoke more about 'subjective', internal feelings of safety ('I feel unsafe'), whereas men spoke more about external conditions ('it is a dangerous road'). CONCLUSION: This rare application of machine learning to qualitative social science research has helped to identify potentially important differences in co-occurrence of practices and discourses about practice between men's and women's accounts of travel across diverse contexts. These findings can inform future research and policy decisions for promoting travel-related social practices associated with increased physical activity that are appropriate across genders.

Organised walking groups are increasingly widespread in the UK and elsewhere and have been shown to have many benefits for participants. They tend to attract more women than men, but little is known about how and why walking groups 'recruit' women. This is of particular importance given observed inequalities in physical activity participation by gender, in favour of men. To explore women's participation in walking groups, we conducted ethnographic fieldwork (in May-August 2017) with women members of five different walking groups in deprived areas of north-east England. Participant observation and informal 'go along' interviewing were conducted on 25 group walks, and 20 semi-structured interviews were undertaken. Fieldnotes and interview transcripts were analysed thematically. This paper presents five portraits to show how the identified themes played out in women's lives. For many of the women, the act of moving and socialising together in outdoor environments was highly valued. We show how walking groups found a place within the lives of women, becoming spaces of sharing, healing and enjoyment and acting as a positive resource or "lifeline", often around time-spaces of change (biographical disruptions). We contribute new understandings of how walking groups work by showing how women's reasons for participating were intimately intertwined with their life circumstances and relationships, thus furthering the ongoing theoretical shift from investigating health 'behaviours' to health 'practices'. We conclude that walking groups work well for some people at particular times in their lives, especially (but not only) for older women and, more generally, that life transitions offer an opportunity for interventions to enhance health if they work within the lives of prospective participants.

As part of a process evaluation, we explored in semi-structured interviews the experiences of nineteen mothers who had taken part in a trial to reduce infant formula-milk intake and promote healthy weight gain, and reflections of three facilitators who delivered the intervention and control group protocols. Mothers appreciated the non-judgmental support provided during the trial, after experiencing stigma and receiving limited advice on how, how much and how often formula-milk should be given. The information mothers had previously found, printed on formula-milk tins, or provided by family, friends and health professionals, was often perceived as contradictory; the trial guidance also conflicted with social norms relating infant health positively with weight gain. For those recruited into the trial with older infants, who had already exceeded the recommendations, reducing formula-milk amounts was difficult. The findings highlight the difficulties of addressing a highly stigmatized, complex social practice with an individual, behavioral intervention approach.

Abstract
.
. Background
. Physical activity patterns have been shown to change significantly across the transition to retirement. As most older adults approach retirement as part of a couple, a better understanding of how spousal pairs influence each other’s physical activity behaviour in retirement may help inform more effective interventions to promote physical activity in older age. This qualitative study aimed to explore and describe how couples influence each other’s physical activity behaviour in retirement.
.
.
. Methods
. A qualitative descriptive study that used purposive sampling to recruit seven spousal pairs with at least one partner of each pair recruited from the existing EPIC-Norfolk study cohort in the east of England, aged between 63 and 70 years and recently retired (within 2-6 years). Semi-structured interviews with couples were performed, audio-recorded, transcribed verbatim and analysed using data-driven content analysis.
.
.
. Results
. Three themes emerged: spousal attitude towards physical activity, spouses’ physical activity behaviour and spousal support. While spouses’ attitudes towards an active retirement were concordant, attitudes towards regular exercise diverged, were acquired across the life course and were not altered in the transition to retirement. Shared participation in physical activity was rare and regular exercise was largely an individual and independent habit. Spousal support was perceived as important for initiation and maintenance of regular exercise.
.
.
. Conclusions
. Interventions should aim to create supportive spousal environments for physical activity in which spouses encourage each other to pursue their preferred forms of physical activity; should address gender-specific needs and preferences, such as chances for socialising and relaxation for women and opportunities for personal challenges for men; and rather than solely focusing on promoting structured exercise, should also encourage everyday physical activity such as walking for transport.

We used participant-produced photography to investigate everyday commuting practices in Cambridge, UK. Photovoice served as an observational method for producing ethnographically rich data. A total of 19 participants produced over 500 photos about their journeys to and from work and took part in photo-elicitation interviews. Three themes emerged. First, many images depicted ‘well-being’ in commuting, for example, beautiful landscapes. Second, during elicitation interviews, participants described positive images that they intended but failed to capture in photos. Third, those participants who did not depict well-being described a lack of choice in their commuting, while those who acknowledged well-being seemed to do so in order to make practices of commuting meaningful and habitable. While our interpretations of photos of well-being could be subject to a methodological fallacy relating to a preference for positive over negative images in lay photography, we nonetheless suggest that the rich visual and oral narratives indicate a ‘real’ experience, albeit elicited through the photovoice.

Background:We assessed the quality of data on physical activity obtained by recall from Muslim women of South Asian origin, and the feasibility of using accelerometer-based physical activity monitors to provide more objective measures of physical activity in this group.Methods:In this largely qualitative study, 22 British Pakistani women were asked to wear accelerometers (the GT1M Actigraph and/or the Sensewear Armband) for 4 days, provided 2 24-hour recalls of activities, and were interviewed about their experiences with the monitors.Results:Women reported spending most of their time in housework and childcare, activities which generated the majority of recorded bouts of moderate to vigorous physical activity. However, women had difficulty in recalling the timing, and assessing the intensity, of these usually unstructured activities. A significant minority of accelerometer datasets were incomplete and some women reported either forgetting to wear the acceler-ometer or finding it intrusive.Conclusions:Questionnaires are unlikely to provide an accurate assessment of physical activity in this group of women. This suggests that accelerometer data will be preferable. However, collecting sufficient data for large-scale studies using activity monitors in this population will be challenging.

Abstract
.
. Background
. The transition to retirement has been recognised as a critical turning point for physical activity (PA). In an earlier systematic review of quantitative studies, retirement was found to be associated with an increase in recreational PA but with a decrease in PA among retirees from lower occupational groups. To gain a deeper understanding of the quantitative review findings, qualitative evidence on experiences of and views on PA around the transition to retirement was systematically reviewed and integrated with the quantitative review findings.
.
.
. Method
. 19 electronic databases were searched and reference lists were checked, citations tracked and journals hand-searched to identify qualitative studies on PA around the transition to retirement, published between January 1980 and August 2010 in any country or language. Independent quality appraisal, data extraction and evidence synthesis were carried out by two reviewers using a stepwise thematic approach. The qualitative findings were integrated with those of the existing quantitative systematic review using a parallel synthesis approach.
.
.
. Results
. Five qualitative studies met the inclusion criteria. Three overarching themes emerged from the synthesis of these studies: these related to retirees’ broad concepts of PA, the motives for and the challenges to PA in retirement. Integrative synthesis of the qualitative findings with the quantitative evidence offered several potential explanations for why adults might engage in more recreational PA after the transition to retirement. These included expected health benefits, lifelong PA patterns, opportunities for socialising and personal challenges, and the desire for a new routine. A decrease in PA among retirees from lower occupational groups might be explained by a lack of time and a perceived low personal value of recreational PA.
.
.
. Conclusions
. To encourage adoption and maintenance of PA after retirement, interventions should promote health-related and broader benefits of PA. Interventions for retirees from lower occupational groups should take account of busy post-retirement lifestyles and the low personal value that might be attributed to recreational PA. Future research should address predictors of maintenance of recreational PA after the transition to retirement, the broader benefits of PA, and barriers to PA among retirees from lower occupational groups.

Background Reducing car use and promoting physically active travel would be expected to decrease air pollution, traffic crashes and diseases associated with sedentary lifestyles.

Objective to investigate how and why people commute by car.

Design Mixed-methods cross-sectional study, integrating qualitative data from in-depth interviews with quantitative data from questionnaires.

Setting Cambridge, UK.

Participants Commuters to Cambridge. 47 participants (23−68 years, 26 female) completed interviews, 1142 (17−71 years, 782 female) completed questionnaires.

Outcome measures Regular car commuting, defined as always/usually commuting by car in the past four weeks. We also examined whether regular car commuters drove all the way (unimodal) or used cars plus another mode (multimodal – eg, park and ride).

Analysis Initial qualitative analyses generated hypotheses and conceptual models which we tested in the quantitative data. Key quantitative findings formed the starting point for further thematic analyses of the qualitative data.

Results Regular car commuting was independently associated with female gender, longer commuting distance, having a driving licence, more household cars and availability of workplace parking. There was no independent effect of age, presence of children, long-term illness or difficulty walking. Socio-economic characteristics (education, housing tenure and area deprivation) showed strong univariable effects which appeared entirely mediated by commuting distance. Qualitative analysis suggested that this reflected high house prices in central Cambridge, meaning less wealthy households moved further out to achieve goals such as home ownership. Nevertheless, cars were generally affordable in this relatively affluent population, reducing the barrier which distance posed to labour-force participation. Car access was also valued by many non-regular car commuters in letting them overcome short-term challenges such as illness. Yet car commuting also introduced constraints, for example pushing drivers with flexible working hours to travel earlier (40% of drivers started work by 8:30 vs 20% of walkers and cyclists). Finally, only workplace parking availability strongly predicted unimodal versus multimodal car commuting (90% unimodal if free workplace parking, 65% if charged parking, 20% if no parking). 84% of multimodal car journeys involved walking or cycling.

Conclusion in car-centred environments, car access enables individuals to reconcile life goals such as home ownership and employment, and to meet unexpected challenges. Nevertheless, car dependence also imposes constraints, particularly on those who are less affluent or who have less control over their working hours. Car commuters were much more likely to incorporate some walking or cycling into their journey if their workplace restricted parking or charged for it, suggesting potential health benefits.
