A preventive integrated eHealth approach for individuals with a low socioeconomic position: protocol for a realist evaluation.

BACKGROUND: Adoption of standalone eHealth tools is low among persons in lower socioeconomic groups. The preventive integrated eHealth approach combines blended care with an active and personal approach to facilitate access to local care, tailored to the needs of the participant. We describe the four step preventive integrated eHealth approach for individuals with a low socioeconomic position and the realist evaluation protocol of the intervention and implementation. The realist evaluation centers around the question, 'what works for whom in what circumstances and why'. METHODS: The study population will consist of adult individuals with a low socioeconomic position, who participate in the preventive integrated eHealth approach in one of the participating locations in the Netherlands. The four-step intervention consists of: (1) a proactive invitation of participants by care professionals, (2) the use of an eHealth tool that produces a personalized health report, (3) a personal consultation with a care professional to discuss the personalized health report and set a goal to work on, and (4) active referral to local social and health care. An initial program theory theorized from literature and stakeholder involvement is presented. Qualitative and quantitative data collection and analysis with participants (survey at zero, three and twelve months and focus groups at six months) and professionals (interviews at three months) will inform the realist evaluation and serves to test and refine the initial program theory. DISCUSSION: Our mixed-methods realist evaluation on the effect and implementation of a personal and active blended care approach will elucidate what elements trigger the mechanisms and responses of how individuals with a low socioeconomic position experience the preventive integrated eHealth approach. This will inform the way a preventative health check incorporating eHealth can be used to its full potential for low socioeconomic positioned groups to help close the digital divide and contribute to reduce health disparities.

Understanding educational inequalities in sports participation through structurally based resources and individual agency - a sequential mediation analysis.

Educational inequalities in sports participation remain a public health issue in the Netherlands. Combining structurally based resources from Pierre Bourdieu's theory of capital with Amartya Sen's conceptualization of individual agency may offer new insights into the complex mechanisms that drive these inequalities. Specifically, we posited that the way individuals are able to exercise their agency within the structurally based economic, social, and cultural resources they have access to may help explain educational inequalities in sports participation.Data from two waves of the GLOBE study (2014, 2021) were used to test whether two sequential mediators, structurally based resources followed by individual agency, help explain the relationship between educational level and sports participation. Adults aged 25 and older residing in Eindhoven, the Netherlands self-reported highest attained educational level, structurally based resources (economic, social, and embodied cultural capital), individual agency (self-control, perceived choice, and reflexivity), and sports participation. A sequential mediation analysis using structural equation modelling was used to test the direct effect of education on sports participation, the sequential indirect effect through both mediators, and partial indirect effects through each mediator individually.Educational level was positively associated with sports participation. The hypothesized sequential mediation pathway was not supported; educational level was positively associated with structurally based resources and structurally based resources were positively associated with individual agency, but individual agency was not related to sports participation. Though not through individual agency, structurally based resources helped explain educational inequalities in sports participation.Having access to more economic, social, and cultural resources may empower individuals by increasing their agency. This increased agency was not associated with sports participation, which could be because sports participation is not universally valued as a goal. The conceptualization and operationalization of individual agency in the context of sports participation warrants more research. We found that structurally based resources helped explain a substantial portion of educational inequalities in sport, so we propose that policies alleviating more than just economic barriers to sports participation, but also social and cultural barriers, may help reduce educational inequalities in sports participation in the Netherlands.

Neighborhood Characteristics Related to Changes in Anthropometrics During a Lifestyle Intervention for Persons with Obesity.

BACKGROUND: Since obesity has emerged as a major public health concern, there is an urgent need to better understand factors related to weight gain and treatment success. METHODS: This study included 118 persons with obesity who participated in a multidisciplinary combined lifestyle intervention with cognitive-behavioral therapy at the outpatient clinic of the Obesity Center CGG at Erasmus University Medical Center, Rotterdam, The Netherlands. Neighborhood characteristics were assessed using a 13-item questionnaire. Multiple regression analyses were performed to examine the association between perceived safety, social cohesion, and the availability of facilities on relative changes in body mass index and waist circumference changes, adjusted for corresponding neighborhood socioeconomic status scores. RESULTS: Higher total scores, indicating more unfavorable neighborhood perceptions, were associated with less relative improvements in BMI and waist circumference after 1.5 years (ß = 3.2, 95%CI 0.3-6.0; ß = 3.4, 95%CI 0.3-6.6, respectively). Also, more neighborhood unsafety was associated with less relative improvements in BMI and waist circumference on the long term (ß = 3.1, 95%CI 1.1-5.1; ß = 2.8, 95%CI 0.6-5.1, respectively). CONCLUSION: The results indicate that living in a neighborhood perceived as less favorable may lower the chances of successful weight loss in response to combined lifestyle interventions in persons with obesity.

Effect of fast-food environments on children's eating behaviour: A random effect within between analysis within the Generation R Study.

BACKGROUND: Focussing on appetitive traits associated with obesity, this study aimed to estimate the association between the fast-food environment and satiety responsiveness, enjoyment of food and food responsiveness. METHODS: We used data from the Generation R Study. We included 2008 children with repeated measurements at the age of 4-10 years old. Three eating behaviour subscales from the Child Eating Behaviour Questionnaire (CEBQ) were used as outcomes. Geographical Information System data were used to map individual-level exposure to fast-food outlets within 400 m from home. Random Effect Within Between (REWB) models were used to derive estimates. We tested for moderation of the associations with parental restriction at baseline using the parent-reported Child Feeding Questionnaire (CFQ). RESULTS: We did not find evidence of between-associations of fast-food exposure and eating behaviour subscales. Considering within-associations, an increase in absolute fast-food exposure was associated with a significant marginal increase in satiety responsiveness (ß: 0.02 [95% confidence interval: 0.00-0.03]). No moderation by parental restriction was found. CONCLUSIONS: In environments with ubiquitous fast-food outlets, an increased exposure to fast-food outlets does not seem to have a substantial impact on eating behaviour. Further research is needed to better understand how fast-food exposure contributes to overweight.

Hypothetical mechanisms driving physical activity levels in ethnic minority groups living in Europe: a systematically identified evidence-based conceptual systems model.

BACKGROUND: In Europe, physical activity levels tend to be lower in ethnic minority groups than the general population. Interventions and policies based on research examining isolated determinants of physical activity have had limited success in increasing physical activity levels. This study used systems dynamics theory and the capability approach theoretical framework to develop a conceptual model of how individual characteristics, institutional and physical environments and the migration context may interact to promote or hinder physical activity in ethnic minority groups living in Europe. METHODS: A systematic update of Langøien et al.'s 2017 review of the determinants of physical activity in ethnic minority groups living in Europe was conducted. Our target population included individuals of all ages who reported a familial migration background from any low- and middle-income countries or belonging to minority indigenous population in Europe. Outcomes pertaining to non-work related physical activity of light, moderate or vigorous intensity performed in any setting were included. Included studies provided an evidence base from which to derive the causal loop diagrams comprising our conceptual model. Sub-system causal loop diagrams were interpreted in co-author review sessions to explicate non-linear system mechanisms, such as reinforcing and balancing feedback loops. RESULTS: Forty-one studies were identified, of which the majority was qualitative. The conceptual model consisted of 4 causal loop diagrams relating to psychosocial constructs; sociocultural constructs; health and health communication and social and material resources, in interaction with environmental/migration context. Four hypothetical mechanisms were identified, e.g. hypothesizing that participation in organised activities leads to increased self-efficacy, thereby enabling further participation. CONCLUSIONS: This study contributes an evidence-based conceptual systems model which elucidates how low levels of physical activity in ethnic minority groups in Europe could be supported by reinforcing and balancing mechanisms involving factors relating to physical and institutional environments, migration context and individuals. A pluralistic approach to literature review, integrating complexity methods such as CLDs into more conventional systematic literature review, supports novel insights into how factors could interact to support persistently low levels of activity, moving beyond the identification of potential relationships between isolated factors to indicating the ways in which these relationships are sustained and could be modified by intervention or policy.

Different concepts of neighborhood safety and child internalizing and externalizing behaviors.

Neighborhood safety is defined inconsistently across epidemiologic studies - a conceptual problem that results in incomparable measurements, hampering the design of health interventions. Using child behavior problems (measured via the Child Behavior Checklist) as the outcome of interest, this study directly compared four measures of neighborhood safety: two of experienced safety and two of perceived safety, with each one measured at family and community levels. These included children's direct experience of harm, parental perceptions, community crime statistics, and community perceptions. In a sample of 3291 ten-year-olds from the Generation R cohort (living in municipal Rotterdam, Netherlands, 2013), all four measures were correlated (χ2 ≥ 9.2, P < 0.002 in pairwise chi-square comparisons), but ultimately identified different levels of risk for behavioral health. Direct experiences of harm, parental perceptions, and community crime statistics were all associated with increased child internalizing behaviors (ß = 3.12, ß = 2.10, and ß = 1.77, respectively), while only experiences of harm and parental perceptions were associated with increased externalizing behaviors (ß = 2.75 and ß = 1.31, respectively). These results provide novel evidence that the conceptual distinctions underlying different measures of neighborhood safety are meaningful for child mental health and should be considered in intervention design.

Longitudinal study of changes in greenness exposure, physical activity and sedentary behavior in the ORISCAV-LUX cohort study.

BACKGROUND: Greenness exposure has been associated with many health benefits, for example through the pathway of providing opportunities for physical activity (PA). Beside the limited body of longitudinal research, most studies overlook to what extent different types of greenness exposures may be associated with varying levels of PA and sedentary behavior (SB). In this study, we investigated associations of greenness characterized by density, diversity and vegetation type with self-reported PA and SB over a 9-year period, using data from the ORISCAV-LUX study (2007-2017, n = 628). METHODS: The International Physical Activity Questionnaire (IPAQ) short form was used to collect PA and SB outcomes. PA was expressed as MET-minutes/week and log-transformed, and SB was expressed as sitting time in minutes/day. Geographic Information Systems (ArcGIS Pro, ArcMap) were used to collect the following exposure variables: Tree Cover Density (TCD), Soil-adjusted Vegetation Index (SAVI), and Green Land Use Mix (GLUM). The exposure variables were derived from publicly available sources using remote sensing and cartographic resources. Greenness exposure was calculated within 1000m street network buffers around participants' exact residential address. RESULTS: Using Random Effects Within-Between (REWB) models, we found evidence of negative within-individual associations of TCD with PA (ß = - 2.60, 95% CI - 4.75; - 0.44), and negative between-individual associations of GLUM and PA (ß = - 2.02, 95% CI - 3.73; - 0.32). There was no evidence for significant associations between greenness exposure and SB. Significant interaction effects by sex were present for the associations between TCD and both PA and SB. Neighborhood socioeconomic status (NSES) did not modify the effect of greenness exposure on PA and SB in the 1000 m buffer. DISCUSSION: Our results showed that the relationship between greenness exposure and PA depended on the type of greenness measure used, which stresses the need for the use of more diverse and complementary greenness measures in future research. Tree vegetation and greenness diversity, and changes therein, appeared to relate to PA, with distinct effects among men and women. Replication studies are needed to confirm the relevance of using different greenness measures to understand its' different associations with PA and SB.

Childhood obesity's influence on socioeconomic disparities in young adolescents' mental health.

PURPOSE: We investigated whether socioeconomic inequalities in young adolescents' mental health are partially due to the unequal distribution of childhood obesity across socioeconomic positions (SEP), i.e. differential exposure, or due to the effect of obesity on mental health being more detrimental among certain SEPs, i.e. differential impact. METHODS: We studied 4660 participants of the Generation R study, a population-based study in the Netherlands. SEP was estimated by mother's education and household income at age five of the child. We estimated the contribution of the mediating and moderating effects of high body fat percentage to the disparity in mental health. This was done through a four-way decomposition using marginal structural models with inverse probability of treatment weighting. RESULTS: Comparing children with the least to most educated mothers and the lowest to highest household income, the total disparity in emotional problems was 0.98 points (95%CI:0.35-1.63) and 1.68 points (95%CI:1.13-2.19), respectively. Of these total disparities in emotional problems, 0.50 points (95%CI:0.15-0.85) and 0.24 points (95%CI:0.09-0.46) were due to the differential exposure to obesity. Obesity did not contribute to disparities in behavioural problems. CONCLUSION: Addressing the heightened obesity prevalence among children in low SEP families may reduce inequalities in emotional problems in early adolescence.

Tunneling, cognitive load and time orientation and their relations with dietary behavior of people experiencing financial scarcity - an AI-assisted scoping review elaborating on scarcity theory.

BACKGROUND: The concept of a financial scarcity mindset has raised much attention as an explanation for poor decision-making and dysfunctional behavior. It has been suggested that financial scarcity could also impair dietary behavior, through a decline in self-control. Underlying cognitive mechanisms of tunneling (directing attention to financial issues and neglecting other demands), cognitive load (a tax on mental bandwidth interfering with executive functioning) and time orientation (a shift towards a present time horizon, versus a future time horizon) may explain the association between financial scarcity and self-control related dietary behavior. The current scoping review gathers recent evidence on how these mechanisms affect dietary behavior of people experiencing financial scarcity. It builds on a theoretical framework based on insights from behavioral economics and health psychology. METHODS: A literature search was executed in six online databases, which resulted in 9.975 papers. Search terms were tunneling, cognitive load and time orientation, financial scarcity, and dietary behavior. Screening was performed with ASReview, an AI-ranking tool. In total, 14 papers were included in the scoping review. We used PRISMA-ScR guidelines for reporting. RESULTS: Limited evidence indicates that a scarcity mindset could increase tunneling, through attentional narrowing on costs of food, which then directly impacts dietary behavior. A scarcity mindset involves experiencing financial stress, which can be understood as cognitive load. Cognitive load decreases attentional capacity, which could impair self-control in dietary choices. Financial scarcity is related to a present time orientation, which affects dietary choices by shifting priorities and decreasing motivation for healthy dietary behavior. CONCLUSIONS: A scarcity mindset affects dietary behavior in different ways. Tunneling and a shift in time orientation are indicative of an attentional redirection, which can be seen as more adaptive to the situation. These may be processes indirectly affecting self-control capacity. Cognitive load could decrease self-control capacity needed for healthy dietary behavior because it consumes mental bandwidth. How a changing time orientation when experiencing financial scarcity relates to motivation for self-control in dietary behavior is a promising theme for further inquiry.

Untangling the complex implementation process of community-based health promotion: a multiple-case study in the Netherlands.

Community-based programmes are a widely implemented approach for population health promotion. Due to the context-dependent and dynamic nature of these programmes, evaluating their implementation is challenging. Identifying key events in the implementation process in evaluation could enable us to support future implementation, while acknowledging the complexity of real-world implementation. We studied the nationwide implementation of the Dutch Healthy Youth, Healthy Future (JOGG) approach, a community-based programme for childhood overweight prevention. The aims of our study were (i) to gain insights into the implementation process of the JOGG approach, and (ii) to identify key events that influenced said process. In nine communities, we conducted interviews (n = 24) with coordinators and stakeholders involved in the implementation of the JOGG approach and collected documents on the programme's implementation. We applied the analytical tool 'Critical Event Card' to identify key events in the implementation process. Results showed that in 5-10 years of implementing the JOGG approach, communities have undergone different phases: preparation, upscaling, resource mobilization, integration with other policy initiatives and adaptation of the implementation strategy. Key events influencing the implementation process included national policy developments (e.g. new health programmes), framing of the JOGG approach in local policy, staff turnover and coordination teams' experiences and actions. Furthermore, changes in implementation were often triggered by the destabilization of the implementation process and linked to opportunities for change in the policy process. The identified key events can inform future implementation of the JOGG approach as well as other community-based health promotion programmes.

Why we struggle to make progress in obesity prevention and how we might overcome policy inertia: Lessons from the complexity and political sciences.

Despite evidence for the effectiveness of policies that target obesogenic environments, their adoption remains deficient. Using methods and concepts from complexity and political science (Stock-and-Flow analysis and Punctuated Equilibrium Theory) and a qualitative literature review, we developed system maps to identify feedback loops that hinder policymaking on mitigating obesogenic environments and feedback loops that could trigger and sustain policy change. We found numerous self-reinforcing feedback loops that buttress the assumption that obesity is an individual problem, strengthening the biomedical and commercial weight-loss sectors' claim to "ownership" over solutions. That is, improvements in therapies for individuals with obesity reinforces policymakers' reluctance to target obesogenic environments. Random events that focus attention on obesity (e.g., celebrities dismissing soda) could disrupt this cycle, when actors from outside the medical and weight-loss sector (e.g., anti-weight stigma activists) successfully reframe obesity as a societal problem, which requires robust and politically relevant engagement with affected communities prior to such events taking place. Sustained prioritization of policies targeting obesogenic environments requires shared problem ownership of affected communities and nonhealth government sectors, by emphasizing cobenefits of policies that target obesogenic environments (e.g., ultraprocessed food taxation for raising revenue) and solutions that are meaningful for affected communities.

Do financial constraint and perceived stress modify the effects of food tax schemes on food purchases: moderation analyses in a virtual supermarket experiment.

OBJECTIVE: To investigate whether financial constraint and perceived stress modify the effects of food-related taxes on the healthiness of food purchases. DESIGN: Moderation analyses were conducted with data from a trial where participants were randomly exposed to: a control condition with regular food prices, an sugar-sweetened beverage (SSB) tax condition with a two-tiered levy on the sugar content in SSB (5-8 g/100 ml: €0·21 per l and ≥8 g/100 ml: €0·28 per l) or a nutrient profiling tax condition where products with Nutri-Score D or E were taxed at a 20 percent level. Outcome measures were overall healthiness of food purchases (%), energy content (kcal) and SSB purchases (litres). Effect modification was analysed by adding interaction terms between conditions and self-reported financial constraint or perceived stress in regression models. Outcomes for each combination of condition and level of effect modifier were visualised. SETTING: Virtual supermarket. PARTICIPANTS: Dutch adults (n 386). RESULTS: Financial constraint or perceived stress did not significantly modify the effects of food-related taxes on the outcomes. Descriptive analyses suggest that in the control condition, the overall healthiness of food purchases was lowest, and SSB purchases were highest among those with moderate/high levels of financial constraint. Compared with the control condition, in a nutrient profiling tax condition, the overall healthiness of food purchases was higher and SSB purchases were lower, especially among those with moderate/high levels of financial constraint. Such patterns were not observed for perceived stress. CONCLUSION: Further studies with larger samples are recommended to assess whether food-related taxes differentially affect food purchases of subgroups.

Public support for smoke-free private indoor and public outdoor areas in the Netherlands: A trend analysis from 2018-2022.

INTRODUCTION: In addition to smoke-free policies in indoor public and workplaces, governments increasingly implement smoke-free policies at beaches, in parks, playgrounds and private cars ('novel smoke-free policies'). An important element in the implementation of such policies is public support. In the context of the ambition of the Netherlands to reach a smoke-free generation by 2040, we investigated temporal changes in public support for novel smoke-free policies. METHODS: We analyzed annual cross-sectional questionnaires in a representative sample of the Dutch population from 2018 to 2022. Multivariable logistic regression was applied to model public support for each smoke-free policy area as a function of time (calendar year), smoking status, gender, and socioeconomic status. Interaction terms were added for time with smoking status and with socioeconomic status. RESULTS: A total of 5582 participant responses were included. Between 2018 and 2022, support increased most for smoke-free policies regarding train platforms (+16%), theme parks (+12%), beaches (+10%), and terraces (+10%). In 2022, average support was higher than 65% for all categories of smoke-free places and highest for private cars with children (91%). Regression analyses indicated significant increases in support over time within each category of smoke-free places (adjusted odds ratio, AOR between 1.09 and 1.17 per year), except smoke-free private cars with children (AOR=0.97; 95% CI: 0.89-1.05). Regardless of smoking status, support was high for places where children often go. CONCLUSIONS: Support for novel smoke-free places in the Netherlands is high and increasing, in particular for places frequented by children. This indicates the potential to implement such measures in the Netherlands.

Socio-economic inequalities in smoking and drinking in adolescence: Assessment of social network dynamics.

AIMS: We investigated whether (1) adolescents selected friends with a similar socio-economic status (SES), (2) smoking and alcohol consumption spread in networks and (3) the exclusion of non-smokers or non-drinkers differed between SES groups. DESIGN: This was a longitudinal study using stochastic actor-oriented models to analyze complete social network data over three waves. SETTING: Eight Hungarian secondary schools with socio-economically diverse classes took part. PARTICIPANTS: This study comprised 232 adolescents aged between 14 and 15 years in the first wave. MEASUREMENTS: Self-reported smoking behavior, alcohol consumption behavior and friendship ties were measured. SES was measured based upon entitlement to an income-tested regular child protection benefit. FINDINGS: Non-low-SES adolescents were most likely to form friendships with peers from their own SES group [odds ratio (OR) = 1.07, 95% confidence interval (CI) = 1.02-1.11]. Adolescents adjusted their smoking behavior (OR = 24.05, 95% CI = 1.27-454.86) but not their alcohol consumption (OR = 1.65, 95% CI = 0.62-4.39) to follow the behavior of their friends. Smokers did not differ from non-smokers in the likelihood of receiving a friendship nomination (OR = 0.98, 95% CI = 0.87-1.10), regardless of their SES. Alcohol consumers received significantly more friendship nominations than non-consumers (OR = 1.16, 95% CI = 1.01-1.33), but this association was not significantly different according to SES. CONCLUSIONS: Hungarian adolescents appear to prefer friendships within their own socio-economic status group, and smoking and alcohol consumption spread within those friendship networks. Socio-economic groups do not differ in the extent to which they encourage smoking or alcohol consumption.

Association of Neighborhood Deprivation and Depressive Symptoms With Epigenetic Age Acceleration: Evidence From the Canadian Longitudinal Study on Aging.

BACKGROUND: Neighborhood deprivation and depression have been linked to epigenetic age acceleration. The next-generation epigenetic clocks including the DNA methylation (DNAm) GrimAge, and PhenoAge have incorporated clinical biomarkers of physiological dysregulation by selecting cytosine-phosphate-guanine sites that are associated with risk factors for disease, and have shown improved accuracy in predicting morbidity and time-to-mortality compared to the first-generation clocks. The aim of this study is to examine the association between neighborhood deprivation and DNAm GrimAge and PhenoAge acceleration in adults, and assess interaction with depressive symptoms. METHODS: The Canadian Longitudinal Study on Aging recruited 51 338 participants aged 45-85 years across provinces in Canada. This cross-sectional analysis is based on a subsample of 1 445 participants at baseline (2011-2015) for whom epigenetic data were available. Epigenetic age acceleration (years) was assessed using the DNAm GrimAge and PhenoAge, and measured as residuals from regression of the biological age on chronological age. RESULTS: A greater neighborhood material and/or social deprivation compared to lower deprivation (b = 0.66; 95% confidence interval [CI] = 0.21, 1.12) and depressive symptoms scores (b = 0.07; 95% CI = 0.01, 0.13) were associated with higher DNAm GrimAge acceleration. The regression estimates for these associations were higher but not statistically significant when epigenetic age acceleration was estimated using DNAm PhenoAge. There was no evidence of a statistical interaction between neighborhood deprivation and depressive symptoms. CONCLUSIONS: Depressive symptoms and neighborhood deprivation are independently associated with premature biological aging. Policies that improve neighborhood environments and address depression in older age may contribute to healthy aging among older adults living in predominantly urban areas.

Climate distress, climate-sensitive risk factors, and mental health among Tanzanian youth: a cross-sectional study.

BACKGROUND: Climate change threatens youth mental health through multiple mechanisms, yet empirical studies typically focus on single pathways. We explored feelings of distress over climate change among Tanzanian youth, considering associations with climate change awareness and climate-sensitive risk factors, and assessed how these factors relate to mental health. METHODS: Tanzanian youth (aged 18-23 years) from a cluster randomised controlled trial in Mbeya and Iringa regions of Tanzania were interviewed between Jan 25, and March 3, 2021, and included in this cross-sectional study. A threshold of at least 10 on the ten-item Centre for Epidemiological Studies Depression Scale was used to classify symptom severity indicative of depression. Regardless of climate change awareness, respondents were asked about their feelings of distress on climate change using inclusive language (changing weather patterns or changing seasons). We estimated rate differences in climate change distress (slight or moderate or extreme vs none) by youth characteristics, extent of climate awareness, and climate-sensitive livelihoods (eg, agriculture, tending livestock) and climate-sensitive living conditions (eg, food or water insecurity), using generalised linear models. We compared depression prevalence by extent of climate change distress and climate-sensitive living conditions. FINDINGS: Among 2053 youth (1123 [55%] were male and 930 [45%] were female) included in this analysis, 946 (46%) had reported any distress about climate change. Distress was higher among female, more educated, more religious, older youth, and those working in extreme temperatures. Adjusting for climate awareness-a factor strongly associated with climate distress-helped to explain some of these associations. Depression was 23 percentage points (95% CI 17-28) higher among youth who had severe water insecurity than those who did not. Similarly, youth who had severe food insecurity had 23 percentage points higher depression (95% CI 17-28) compared with those who did not. Those reporting climate change distress also had worse mental health-extremely distressed youth had 18 percentage points (95% CI 6-30) higher depression than those reporting none. INTERPRETATION: Living in conditions worsened by climate change and feeling distressed over climate change have mental health implications among young people from low-resource settings, indicating that climate change can impact youth mental health through multiple pathways.

Is the association between financial scarcity and health behaviours moderated by cultural capital? The GLOBE study.

BACKGROUND: Experiencing financial scarcity taxes cognitive bandwidth. This leaves less capacity to withhold temptations and makes relying on easiest default options more likely. Whether this default option is (un)healthy may depend on the amount of cultural capital acquired during life course. This study examined whether the association between financial scarcity and health behaviours is moderated by cultural capital. METHODS: Self-reported data were used from Dutch adults of the 2014-survey of the GLOBE study (N = 2466). Using linear regression analysis, financial strain (no, some, great) and cultural capital (institutionalized, objectivized, incorporated) were related to body mass index (BMI), alcohol intake, sports participation, cycling and walking, fruit intake and vegetable consumption. The interaction between financial strain and cultural capital was used to assess moderation. RESULTS: Experiencing some financial strain was associated with a higher BMI (0.7 kg/m2) and less sport participation (-31.8 min/week). Great financial strain was associated with less sport participation (-41.4 min/week). Being in the lowest tertile of cultural capital was associated with a higher BMI (1.3 kg/m2), drinking less alcohol (-10.0 units/week), less sport participation (-31.5 min/week) and consuming less fruit (-2.9 pieces/week). Cultural capital had no significant moderating effect on the relationship between financial strain and these health behaviours. CONCLUSION: Financial strain and cultural capital seem associated with different health behaviours. Cultural capital had no moderating effect on the relationship between financial strain and different health behaviours. While financial strain and cultural capital could both be entry points for interventions to improve health behaviour, underlying mechanisms require further attention.

Healthy immigrants, unhealthy ageing? Analysis of health decline among older migrants and natives across European countries.

The probability of having multiple chronic conditions simultaneously, or multimorbidity, tends to increase with age. Immigrants face a particularly high risk of unhealthy ageing. This study investigates the immigrant-native disparities in the speed of age-related chronic disease accumulation, focusing on the number of chronic health conditions; and considers the heterogeneity of this trajectory within immigrant populations by origin and receiving country. We use data from the Survey of Health, Ageing and Retirement in Europe from 2004 to 2020 on adults aged 50 to 79 from 28 European countries and employ both cross-sectional and longitudinal analyses. For longitudinal panel analyses, we use fixed-effects regression models to account for the unobserved heterogeneity related to individual characteristics including migration background. Our results indicate that immigrants report a higher number of chronic conditions at all ages relative to their native-born peers, but also that the immigrant-native differential in the number of chronic conditions decreases from age 65 onwards. When considering differences by origin country, we find that the speed of chronic disease accumulation is slower among immigrants from the Americas and the Asia and Oceania country groups than it is among natives. When looking at differences by receiving country group, we observe that the speed of accumulating chronic diseases is slower among immigrants in Eastern Europe than among natives, particularly at older ages. Our findings suggest that age-related trajectories of health vary substantially among immigrant populations by origin and destination country, which underscore that individual migration histories play a persistent role in shaping the health of ageing immigrant populations throughout the life course.

The role of labor market inequalities in explaining the gender gap in depression risk among older US adults.

We aim to investigate to what extent gender inequality at the labor market explains higher depression risk for older US women compared to men. We analyze data from 35,699 US adults aged 50-80 years that participated in the Health and Retirement Study. The gender gap is calculated as the difference in prevalence in elevated depressive symptoms (score ≥ 3 on the 8-item Center for Epidemiological Studies Depression Scale) between women and men. We employ a dynamic causal decomposition and simulate the life course of a synthetic cohort from ages 50-80 with the longitudinal g-formula and introduce four nested interventions by assigning women the same probabilities of A) being in an employment category, B) occupation class, C) current income and D) prior income group as men, conditional on women's health and family status until age 70. The gender gap in depression risk is 2.9%-points at ages 50-51 which increases to 7.6%-points at ages 70-71. Intervention A decreases the gender gap over ages 50-71 by 1.2%-points (95%CI for change: 2.81 to 0.4), intervention D by 1.64%-points (95%CI for change: 3.28 to -0.15) or 32% (95%CI: 1.39 to 62.83), and the effects of interventions B and C are in between those of A and D. The impact is particularly large for Hispanics and low educated groups. Gender inequalities at the labor market substantially explain the gender gap in depression risk in older US adults. Reducing these inequalities has the potential to narrow the gender gap in depression.

Micro urban spaces and mental well-being: Measuring the exposure to urban landscapes along daily mobility paths and their effects on momentary depressive symptomatology among older population.

The urban environment plays an important role for the mental health of residents. Researchers mainly focus on residential neighbourhoods as exposure context, leaving aside the effects of non-residential environments. In order to consider the daily experience of urban spaces, a people-based approach focused on mobility paths is needed. Applying this approach, (1) this study investigated whether individuals' momentary mental well-being is related to the exposure to micro-urban spaces along the daily mobility paths within the two previous hours; (2) it explored whether these associations differ when environmental exposures are defined considering all location points or only outdoor location points; and (3) it examined the associations between the types of activity and mobility and momentary depressive symptomatology. Using a geographically-explicit ecological momentary assessment approach (GEMA), momentary depressive symptomatology of 216 older adults living in the Ile-de-France region was assessed using smartphone surveys, while participants were tracked with a GPS receiver and an accelerometer for seven days. Exposure to multiple elements of the streetscape was computed within a street network buffer of 25 m of each GPS point over the two hours prior to the questionnaire. Mobility and activity type were documented from a GPS-based mobility survey. We estimated Bayesian generalized mixed effect models with random effects at the individual and day levels and took into account time autocorrelation. We also estimated fixed effects. A better momentary mental wellbeing was observed when residents performed leisure activities or were involved in active mobility and when they were exposed to walkable areas (pedestrian dedicated paths, open spaces, parks and green areas), water elements, and commerce, leisure and cultural attractors over the previous two hours. These relationships were stronger when exposures were defined based only on outdoor location points rather than all location points, and when we considered within-individual differences compared to between-individual differences.
