DNA methylation signatures of prenatal socioeconomic position associated with 36-month language outcomes.

BACKGROUND: Socioeconomic position (SEP), which reflects one's position in society and access to resources, is strongly tied to neurodevelopment and is associated with epigenetic changes. AIM: This study examined whether DNA methylation signatures of prenatal SEP, measured in birth samples, are associated with child neurodevelopmental outcomes at 36 months of age. METHODS: Prenatal SEP DNA methylation scores were derived using 97 placenta and 127 cord blood biospecimens in the Early Autism Risk Longitudinal Investigation cohort. Participants completed the Mullen Scales of Early Learning (MSEL) and Vineland Adaptive Behavior Scales (VABS) at 36 months of age. Generalized regression analyses, adjusting for maternal age and race, were performed to test the association between SEP methylation score, for each birth biospecimen type, and MSEL and VABS scores. RESULTS: Significant associations were observed between placenta SEP methylation score and MSEL Expressive Language outcomes (beta = -2.7, p = 0.046, 95 % CI [- 5.43, -0.05]) and Receptive Language outcomes (beta = -2.5, p = 0.037, 95 % CI [-4.82, -0.16]). In cord blood, methylation-SEP scores were significantly associated with Receptive Language outcomes (beta = -2.0, p = 0.037, 95 % CI [-3.85, -0.12]). No significant associations were observed with VABS scores. CONCLUSION: Our results confirm associations between prenatal SEP and early childhood language development using a novel empiric DNA methylation measure of exposure.

Socioeconomic inequities in alcohol-attributable mortality by sex/gender and age in Canada: A 13-year population-representative cohort study.

Individuals with low socioeconomic position (SEP) experience greater rates of alcohol-attributable mortality, contributing to health inequities in mortality and life expectancy. We examined the association between SEP and alcohol-attributable mortality by sex/gender and age in Canada. Census records from the 2006 Canadian Census Health and Environment Cohort (ages 12+; n=5,038,790) were linked to mortality data from 2006-2019. SEP was measured by educational attainment and household income. Poisson and Fine and Gray sub-distribution hazard models estimated rate differences (RD) per 100,000 person-years and hazard ratios (HR). Both educational attainment and household income were inversely associated with alcohol-attributable mortality. Absolute SEP inequities were greater among men than women, with a RD of 30.81 (95% CI: 28.04, 33.57) for men and 9.86 (95% CI: 8.49, 11.22) for women when comparing the lowest to the highest income quintile. Age-stratified analyses showed absolute SEP inequities were most pronounced in middle and older adulthood, above age 30 for women and age 50 for men, with smaller RDs in ages 12-29. Relative SEP inequities were similar in women and men, with greater HRs at younger ages. Public health policies addressing social determinants and population-level alcohol policies should consider patterning of SEP inequities by sex/gender and age group.

Midlife health in Britain and the United States: a comparison of two nationally representative cohorts.

BACKGROUND: Older adults in the USA have worse health and wider socioeconomic inequalities in health compared with those in Britain. Less is known about how health in the two countries compares in mid-life, a time of emerging health decline, including inequalities in health. METHODS: We compare measures of current regular smoking status, obesity, self-rated health, cholesterol, blood pressure and glycated haemoglobin using population-weighted modified Poisson regression in the 1970 British Cohort Study (BCS70) in Britain (N = 9665) and the National Longitudinal Study of Adolescent to Adult Health (Add Health) in the USA (N = 12 300), when cohort members were aged 34-46 and 33-43, respectively. We test whether associations vary by early- and mid-life socioeconomic position. RESULTS: US adults had higher levels of obesity, high blood pressure and high cholesterol. Prevalence of poor self-rated health and current regular smoking was worse in Britain. We found smaller socioeconomic inequalities in mid-life health in Britain compared with the USA. For some outcomes (e.g. smoking), the most socioeconomically advantaged group in the USA was healthier than the equivalent group in Britain. For other outcomes (hypertension and cholesterol), the most advantaged US group fared equal to or worse than the most disadvantaged groups in Britain. CONCLUSIONS: US adults have worse cardiometabolic health than British counterparts, even in early mid-life. The smaller socioeconomic inequalities and better overall health in Britain may reflect differences in access to health care, welfare systems or other environmental risk factors.

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.

Household income is associated with attack frequency, but not with the prevalence of headache: an analysis of self-reported headache in the general population in Germany.

BACKGROUND: Headache disorders are among the most prevalent neurological disorders worldwide. However, whether groups differing in socioeconomic position (SEP) are disproportionately affected by headache disorders has not yet been adequately clarified. Our aim was to analyse (1) the headache prevalence by socioeconomic position (SEP) and (2) the attack frequency by SEP in a German population-based adult sample. METHODS: Cross-sectional data from a random general population were used. The sample included N = 2,189 participants aged ≥ 18 years. SEP was measured using net equivalised income (NEI) and education. A binary logistic regression model tested the effect of SEP in predicting the prevalence of headache in general. Ordinal logistic regressions were modeled to predict the effect of SEP on the likelihood of attack frequency. Attack frequency was categorized in low frequency episodic headache (LFEH: 0-3 days per month), moderate frequency episodic headache (MFEH: 4-14 days per month) and chronic headache (CH: ≥ 15 days per month). RESULTS: Of the 2,189 participants, 891 reported headache in the last six months. Neither income nor education was associated with headache prevalence. However, significant differences between income groups were found for attack frequency. Compared to participants with NEI > 150%, those with NEI < 60% were 5.21 times more likely (95%CI 2.03, 13.36) to experience higher headache frequency, and those with NEI between 60 and 150% were 2.29 times more likely (95%CI 1.02, 5.11), with adjustments made for a set of potential confounders, including depressive symptoms. CONCLUSIONS: To reduce headache attacks, it is essential to address both low- and middle-income groups affected by headaches. Universal public health prevention campaigns are particularly appropriate.

Does maternal education moderate the relationship between adolescent cannabis use and mental health in early adulthood?

INTRODUCTION: Socioeconomic disadvantage has been associated with cannabis use and poor mental health. It is therefore hypothesised that lower maternal education, a proxy for socioeconomic disadvantage, may increase the risk of cannabis-related mental health and substance use consequences. METHODS: A total of 5099 participants from the Avon Longitudinal Study of Parents and Children reported cannabis use via questionnaires at 16 or 18. Logistic regression was used to examine the relationship between any and regular (weekly or more) adolescent cannabis use with depression, anxiety, psychotic experiences, and problematic cannabis use at age 24. Maternal education was included as an effect modifier. Missing data were addressed through multiple imputation using chained equations. RESULTS: In total, 36.5% of participants reported adolescent cannabis use and, of these, 14% reported regular use. Adolescent cannabis use was associated with an increased likelihood of anxiety and problematic cannabis use; however, there was little evidence of moderation by maternal education. Regular cannabis use was associated with an increased likelihood of problematic cannabis use, with little evidence of moderation by maternal education. There was weak evidence that the association between regular cannabis use and depression (interaction p-value = 0.024) and anxiety (interaction p-value = 0.056) was stronger in people with high maternal education. DISCUSSION AND CONCLUSIONS: Adolescent cannabis use is associated with increased risk of anxiety and cannabis use disorder, but there was insufficient evidence that childhood socioeconomic position (proxied by maternal education) modifies this relationship. Improved public health messages for all adolescents about these risks may be warranted.

Mental health and timing of gender-related events among transgender and gender-diverse children and adolescents seeking gender-affirming consultation and care.

Transgender and gender-diverse (TGD) youth encounter unique challenges affecting their mental health, largely related to societal stigma and gender dysphoria. Limited research considers the specific needs of TGD youth. This study examined demographic and developmental factors, including the ages at which gender-related events occur, and their relationship to mental health among TGD youth seeking gender-affirming consultation and care (GACC). We examined the medical records of 674 TGD children and adolescents, comparing demographics, gender-related events, and mental health across gender groups. The total sample comprised 261 patients assigned male at birth, and 413 patients assigned female at birth. Non-binary individuals reported higher rates of psychopathology compared to binary transgender patients, with transgender boys exhibiting higher rates than transgender girls. Seeking GACC at a more advanced pubertal stage and older age was associated with an increased likelihood of psychopathology. Later recollection of first gender incongruence memory was correlated with higher rates of depression and anxiety. Finally, socioeconomic status was linked to GACC healthcare-seeking behaviors. These findings underscore the importance of recognizing the diverse experiences and needs of TGD youth seeking GACC services, highlighting that early identification and access to care may be crucial for improving mental health outcomes.

Exploring the importance of family socio-economic position on the association between parental BMI and offspring BMI trajectories.

PURPOSE: We aimed to investigate the associations between parental BMI and offspring BMI trajectories and to explore whether the parent-offspring BMI growth trajectory association differed according to family SEP or social mobility. METHODS: We used data from the Avon Longitudinal Study of Parents and Children (ALSPAC). Children's weight and height were collected from 1 to 18 years. Parents' height and weight were reported pre-pregnancy. We assessed family SEP by measuring parents' and grandparents' educational attainment, social class, and social mobility by changes in education attainment across generations. Multilevel models were used to develop trajectories and assess patterns of change in offspring BMI, to associate parental BMI with these trajectories, and explore whether these associations differed by family SEP and social mobility. RESULTS: 13,612 children were included in the analyses. The average BMI of offspring whose parents were overweight or obese was higher throughout childhood and adolescence, compared to those with parents of normal BMI. Parental and grandparental low SEP were associated with higher child BMI, but there was little evidence of modification of parent-offspring associations. For example, at age 15 years the predicted mean BMI difference between children of overweight or obese mothers versus normal-weight mothers was 12.5 % (95 %CI: 10.1 % to 14.7 %) and 12.2 % (95 %CI: 10.3 % to 13.7 %) for high and low grandparental SEP, respectively. DISCUSSION: These findings strengthen the evidence that higher parental BMI and lower family SEP were associated with higher offspring BMI, but we did not observe strong evidence that family SEP modifies the parental-offspring BMI association.

Cross-sectional associations between patterns of cultural engagement and indicators of biological dysregulation.

BACKGROUND: Research has shown that cultural activities may bring about improved health. However, large-scale quantitative analyses on cultural engagement and biomarkers are lacking to date. As a result, the mechanisms through which cultural activities may be associated with health are unclear. AIM: Test quantitative associations between cultural engagement pattern (including active and passive engagement in arts, sports, and heritage activities) and indicators of biological dysregulation in a large dataset. SUBJECTS AND METHODS: Understanding Society data were used to conduct cross-sectional linear regression analyses between a data-driven latent class model of cultural engagement and indicators of anthropometric, cardiovascular, metabolic, immune, and neuroendocrine function. Analyses were adjusted for age, gender, ethnicity, childcare responsibility, urbanicity, leisure time satisfaction, capacity-related factors, socioeconomic position, social and economic capital indicators, physical activity, and medication use. RESULTS: More culturally participants had better indicators of biological health, such as lower waist circumference and fibrinogen blood concentration. Specific associations between cultural engagement pattern and the different biological outcomes were also observed. The associations were explained in part by correlated factors (accounting for around half of the association). CONCLUSIONS: Cultural engagement is cross-sectionally associated with biomarkers, although the characteristics of people who engage with culture are an important consideration when interpreting these findings.

Association between socioeconomic position of the household head, food insecurity and psychological health: an application of propensity score matching.

BACKGROUND: Mental health outcomes can be influenced by various factors, one of which has recently gained attention, namely food security. Food security is paramount to maintaining not only physical, but also mental health. There is an increasing need to understand the interplay between food insecurity (FI) and mental health outcomes, especially among vulnerable populations. The objective of this study was to investigate the effect of FI on psychological health (anxiety and depression) as well as to examine the modifying effect of socioeconomic position on this relationship. METHODS: A cross-sectional study was conducted in Maputo City, Mozambique, in 1,842 participants. Data were collected through structured interviews using a modified version of the US Department of Agriculture Household Food Security Module to measure FI, and the Hospital Anxiety and Depression Scale to measure anxiety and depression. A composite variable for psychological health was created. Propensity score matching and interaction effect analyses were employed to examine the effects of FI on psychological health and the moderating role of socioeconomic position. RESULTS: Of the 1,174 participants randomly assigned to propensity score matching, 787 were exposed to FI while 387 were unexposed. The analysis revealed stark disparities in psychological health outcomes associated with FI. The risk of poor psychological health among those exposed to FI was 25.79%, which was significantly higher than the 0.26% in unexposed individuals. The risk difference was 25.54% points (95% CI: 22.44-28.63), with a risk ratio of 99.82. Our assessment of population attributable fractions indicated that nearly all the risk for poor psychological health in the exposed group could be ascribed to FI. The interaction effects analysis revealed that socioeconomic status modifies this relationship. Specifically, heads of food-insecure households with a lower socioeconomic position tended to report poor mental health compared to their food-secure counterparts with a higher position. CONCLUSIONS: The findings underscore the profound impact of FI on the mental health of household heads in Maputo City, socioeconomic position being a significant modifier. Addressing household FI along with the socioeconomic position of household heads could be pivotal to mental health promotion, especially among vulnerable populations.

Health care utilization up to 11 years after diagnosis among patients with a hematologic malignancy and its association with socioeconomic position.

PURPOSE: To investigate health care utilization among patients with hematologic malignancies and its association with socioeconomic position (SEP) and compare health care utilization with a cancer-free population. METHODS: Patients with aggressive lymphoma, indolent lymphoma, or multiple myeloma (MM), diagnosed between 1999-2010 and 2015-2019, participated in longitudinal patient-reported outcome research, up to 11 years post-diagnosis. Questionnaires assessed health care utilization at the general practitioner (GP), medical specialist, and additional health care. SEP was based on education and income, categorized as low, medium, or high. Sociodemographic and clinical data were obtained from the Netherlands Cancer Registry. Mixed models and logistic regression analyses were performed. RESULTS: The study included 2319 patients (71% response rate), who completed on average five measurements. Patients with MM reported the highest health care utilization, both at the GP and medical specialist. Low SEP was associated with higher utilization at the GP (medium education ß = - 0.72, p = 0.01; high education ß = - 1.15, p < 0.001) and lower utilization of additional physical (OR = 1.7, p = 0.01) and psychosocial (OR = 1.5, p < 0.05) care, among all patients. For patients with MM, high SEP was also associated with higher utilization of health care at the medical specialist (high education ß = 2.56, p < 0.05). CONCLUSION: Hematologic malignancy-related and SEP-related disparities in health care utilization were observed. To ensure equal access to health consumption, attention is needed for patients with a low SEP to provide better guidance in their cancer (survivorship) care. IMPLICATIONS FOR CANCER SURVIVORS: Improving health literacy and involving informal caregivers and nurse-led patient navigation may help reduce disparities in access to (additional) health care.

Patient Perspectives on a Digital Assistant for Medication Reconciliation: An Interview Study Comparing Socioeconomic Groups.

Medication reconciliation, the process of documenting a patient's medication, is currently a time-consuming and labor-intensive process. To make medication reconciliation more efficient, digital assistants (DAs) offer a promising solution. Especially since human-like digital interfaces tend to be appreciated by more vulnerable populations such as patients in a low socioeconomic position (SEP). Despite the potential of DAs for low-SEP populations in particular, these groups are often not involved during the development and design phase of such digital health interventions. This exclusion may explain the lower adoption rates of digital interventions among low-SEP patients and exacerbate the so-called digital divide. We explored the perceptions and needs of patients across the SEP gradient using a participatory design approach. Patients of low-, middle-, and high-SEP backgrounds were asked to interact with a DA developed for this study and were interviewed afterward. A thematic analysis revealed seven themes regarding design, input method, comprehensibility, privacy concerns, benefits, the intention to use, and reassurance. Overall, patients were afraid to make mistakes in their medication entries and therefore valued feedback from the system or caregivers. Low-SEP patients specifically seemed to value more structured input methods when using the DA, while high-SEP patients emphasized the importance of a secure environment for the DA and sought clarity about its functionalities. Our study demonstrates the importance of involving patients across the socioeconomic gradient when developing a digital health tool and offers concrete recommendations for inclusive DA design for researchers and developers.

Examining the effectiveness of food literacy interventions in improving food literacy behavior and healthy eating among adults belonging to different socioeconomic groups- a systematic scoping review.

BACKGROUND: In high-income countries, significant diet-related health inequalities exist between people of different socioeconomic backgrounds. Individuals who face socioeconomic challenges are less likely to meet dietary guidelines, leading to increased incidence and prevalence of morbidity and mortality associated with dietary risk factors. To promote healthy eating, strategies may focus on individual-level factors (e.g., knowledge, skills, and behavior) along with broader societal factors (e.g., social determinants of health). The concept of food literacy is considered an individual-level factor and has been framed as a skill set that individuals must possess to effectively navigate the complexities of the modern food system. Food literacy interventions can be a complementary but effective tool for encouraging healthy eating behavior among diverse populations, including those facing socioeconomic disadvantage. However, there is limited evidence to guide the design of food literacy intervention for vulnerable population groups. In the process of developing an ideal portfolio of solutions and strategies to promote food literacy and healthy eating for people experiencing socioeconomic disadvantage, this systematic scoping review aims to comprehensively examine the effects of food literacy interventions on promoting food literacy behavior and healthy eating in adults (18 years and above) from various socioeconomic groups (SEGs) in high-income countries. METHODS: The review includes both qualitative and quantitative papers obtained from academic databases, including MEDLINE (via EBSCOhost), Embase, Web of Science, and Google Scholar. In addition to the electronic search, manual forward and backward citation searching will be conducted to identify additional relevant papers. Food literacy interventions will be evaluated across four domains: planning and management, selection, preparation, and consumption. Papers included in the review will be analyzed for process, impact, and outcome evaluation. The main outcome of a food literacy intervention is the modification in eating behavior, while the mechanism for this action will be through impact measure of food literacy behaviors. Implementation factors will be extracted for process evaluation. This review will also include a range of dietary behavior measures, such as diet quality index and dietary intake indicator. The screening process for all citations, full-text articles, and abstract data will be carried out by two reviewers independently. In case of any potential conflicts, they will be resolved through discussion. The quality of quantitative studies will be reviewed using the JBI critical appraisal checklist for analytical cross-sectional studies. The "Consolidated Criteria for Reporting Qualitative Studies (COREQ)" will be used to report on the quality of qualitative papers.

Citizens' perspectives on healthy weight approaches in low SEP neighborhoods: a qualitative study from a systems perspective.

BACKGROUND: The physical and the social environment are important predictors of healthy weight, especially in low socioeconomic position (SEP) neighborhoods. Many Dutch municipalities have implemented a healthy weight approach (HWA). Yet, there is room for improvement. This system science study examined what influences the utilization of HWA facilities and activities, and what aspects can help to achieve a desired systems change (also called leverage point themes (LPTs)) in the HWA system as perceived by citizens living in low SEP neighborhoods. METHOD: All research phases were performed with four citizens co-researchers. Forty-seven citizens living in low SEP neighborhoods were semi-structurally interviewed about the neighborhood HWA facilities and municipal HWA activities. A rapid coding qualitative analysis approach was applied per topic. The topics were citizens' healthy living description, personal circumstances, and satisfaction with foot and cycle paths, sports facilities, playgrounds, green spaces, museums and theaters, community centers, churches, healthcare, school, food supplies, contact with neighborhood, unfamiliar and/or unused activities, familiar and used activities, unavailable but desired (lacking) activities, and reaching citizens. RESULTS: The utilization of HWA facilities and activities was influenced by the overarching themes of social cohesion, familiarity, reaching citizens, maintenance, safety, physical accessibility, financial accessibility, social accessibility, fit with personal context, and fit with the neighborhood's specific needs. Different overarching themes stood out across different facilities and activities. LPTs indicated the overarching themes needed in combination with one another for a specific activity or facility to increase utilization. For example, the LPT regarding foot and cycle paths was "accessible, safe, and maintained foot and cycle paths". The LPTs regarding familiar and used activities were "customized activities; information provision (e.g., about possibilities to join without paying); social contact, meeting others, and everyone feels included". CONCLUSION: Conducting inclusive qualitative research from a systems perspective among citizens living in low SEP neighborhoods has contributed valuable insights into their needs. This enables practical implementation of HWAs by providing a deeper understanding of the LPTs within the HWA system. LPTs can help HWA stakeholders to further develop current HWAs toward systems approaches. Future research could study the leverage points that may contribute to LPT implementation.

LifeCourse Socioeconomic Position and Ideal Cardiovascular Health in Hispanic/Latino Adults of the Hispanic Community Health Study/Study of Latinos.

BACKGROUND: The Hispanic/Latino population experiences socioeconomic disadvantages across the lifespan. Yet, little is known about the role of these disadvantages in cardiovascular health (CVH). We assessed the association of lifecourse socioeconomic position (SEP) with ideal CVH and change in Hispanic/Latino adults. METHODS AND RESULTS: We used longitudinal data from the HCHS/SOL (Hispanic Community Health Study/Study of Latinos). Childhood SEP was determined using parental educational attainment. Adult SEP was determined through an index combining participants' education, occupation, income, and assets at baseline. We classified participants into 4 socioeconomic mobility categories (eg, stable low or high SEP, upward or downward mobility). Using the 4 health factors of the American Heart Association "Life's Essential 8," we built a score of ideal CVH at baseline and the 6-year follow-up. Linear mixed-effects models using inverse probability weighting were fitted to assess the main associations. Higher childhood SEP was associated with higher ideal CVH at baseline (ß for high school versus high school versus

Socioeconomic Inequities in Pap Test Use Among Black Women in the United States: An Intersectional Approach.

INTRODUCTION: Research investigating racialized inequities in cervical cancer screening has rarely considered the influence of socioeconomic position (SEP), a key social determinant of health that intersects with race/ethnicity and racism. Thus, data on socioeconomic inequities in Pap test use within racialized groups-including Black women, who are at elevated risk of cervical cancer morbidity and mortality-are limited. METHODS: Using 2011-2019 data from the National Survey of Family Growth and guided by an intersectional framework, we used multivariable logistic regression to examine the association between educational attainment, employment status, and income and the adjusted odds of Pap test use in the last 3 years among Black U.S. women. RESULTS: Compared to Black women with a bachelor's degree or greater, those with less than a high school diploma ([odds ratio] = 0.45; [95% confidence interval] 0.31-0.67) and a high school diploma/GED (0.57; 0.40-0.81) had significantly lower odds of Pap test use, adjusting for sociodemographic factors. Unemployed women had significantly lower adjusted odds of Pap test use compared to employed women (0.67; 0.50-0.89), and women living below 100% of the federal poverty level (FPL) had significantly lower adjusted odds of Pap test use relative to those living at or above 300% FPL (0.63; 0.45-0.88). CONCLUSION: Low-SEP Black women had significantly lower adjusted odds of Pap test use relative to their higher SEP counterparts. Interventions that address both racism and economic barriers to care are needed to facilitate access to regular cervical cancer screening among low-SEP Black women.

Built for movement: Neighborhoods and adolescent physical activity behaviors, and the moderating role of socioeconomic position and gender.

This study examined whether the built environment was associated with physical activity among adolescents in Oslo, Norway, and the role of socioeconomic position and gender as potential moderators of this association. We used data from 897 adolescents who participated in the TACKLE cross-sectional study conducted in 2020. Built environment features (recreational facilities, parks, forest, public transport, traffic calming devices, and schools) were assessed objectively using Geographical Information Systems. Physical activity data included device-measured moderate-to-vigorous physical activity, total physical activity, and self-reported active transportation to school. Using general linear models and logistic regression, we found that most built environment features were unrelated to the participants' device-measured physical activity. Longer distances to school and to traffic calming devices were associated with decreased likelihood of participants reporting active transportation to school. Our moderated regression analysis showed that adolescents with low socioeconomic backgrounds seemed less affected by longer distances to school compared with their high socioeconomic counterparts. Furthermore, boys appeared to be more sensitive to traffic safety relative to girls. Implementing traffic calming devices may enhance active transportation to school and improve traffic safety for Norwegian adolescents.

Frailty and socioeconomic position: A systematic review of observational studies.

BACKGROUND: Frailty, an age-related state of reduced physiological reserve, is often associated with lower socio-economic position (SEP). This systematic review synthesised observational studies assessing (i) the association between SEP and frailty prevalence; (ii) how changes in frailty status over time vary by SEP; and (iii) whether the association between frailty and clinical outcomes is modified by SEP. METHODS: We searched three electronic databases from 2001 to 2023. We included observational studies measuring early-, mid-, and late-life indicators of SEP (education, income, wealth, housing, occupation, and area-based measures of multiple deprivation) and frailty (assessed using any validated measure). Screening and extraction were performed in duplicate. Findings were synthesised using narrative synthesis. RESULTS: We included 383 studies reporting findings from 265 independent samples/cohorts across 64 countries. Lower SEP was associated with higher frailty prevalence across all indicators (childhood deprivation 7/8 studies, education 227/248, occupation 28/32, housing 8/9, income 98/108, wealth 39/44 and area-based deprivation 32/34). Lower SEP was also associated with higher frailty incidence (27/30), with greater odds of transitioning towards a more severe frailty state (35/43), lower odds of frailty reversion (7/11), and (in some studies) with more rapid accumulation of deficits (7/15). The relationship between frailty and mortality was not modified by SEP. INTERPRETATION: Preventative measures across multiple levels of individual and structural inequality are likely to be required to reduce the rising levels of frailty. Resourcing of interventions and services to support people living with frailty should be proportionate to needs in the population to avoid widening existing health inequalities.

Is social disadvantage a chronic stressor? Socioeconomic position and HPA axis activity among older adults living in England.

INTRODUCTION: Living in socioeconomic disadvantage has been conceptualised as a chronic stressor, although this contradicts evidence from studies using hair cortisol and cortisone as a measure of hypothalamus-pituitary-adrenal (HPA)1 axis activity. These studies used complete case analyses, ignoring the impact of missing data for inference, despite the high proportion of missing biomarker data. The methodological limitations of studies investigating the association between socioeconomic position (SEP)2 defined as education, wealth, and social class and hair cortisol and cortisone are considered in this study by comparing three common methods to deal with missing data: (1) Complete Case Analysis (CCA),3 (2) Inverse Probability Weighting (IPW) 4and (3) weighted Multiple Imputation (MI).5 This study examines if socioeconomic disadvantage is associated with higher levels of HPA axis activity as measured by hair cortisol and cortisone among older adults using three approaches for compensating for missing data. METHOD: Cortisol and cortisone levels in hair samples from 4573 participants in the 6th wave (2012-2013) of the English Longitudinal Study of Ageing (ELSA)6 were examined, in relation to education, wealth, and social class. We compared linear regression models with CCA, weighted and multiple imputed weighted linear regression models. RESULTS: Social groups with certain characteristics (i.e., ethnic minorities, in routine and manual occupations, physically inactive, with poorer health, and smokers) were less likely to have hair cortisol and hair cortisone data compared to the most advantaged groups. We found a consistent pattern of higher levels of hair cortisol and cortisone among the most socioeconomically disadvantaged groups compared to the most advantaged groups. Complete case approaches to missing data underestimated the levels of hair cortisol in education and social class and the levels of hair cortisone in education, wealth, and social class in the most disadvantaged groups. CONCLUSION: This study demonstrates that social disadvantage as measured by disadvantaged SEP is associated with increased HPA axis activity. The conceptualisation of social disadvantage as a chronic stressor may be valid and previous studies reporting no associations between SEP and hair cortisol may be biased due to their lack of consideration of missing data cases which showed the underrepresentation of disadvantaged social groups in the analyses. Future analyses using biosocial data may need to consider and adjust for missing data.

Time trends in the clinical management of cervical intraepithelial neoplasia grade 2: A Danish register-based study.

INTRODUCTION: Active surveillance for cervical intraepithelial neoplasia grade 2 (CIN2) has been implemented recently in many countries, including the Nordic countries. In Denmark, the only eligibility criterion for active surveillance for CIN2 is that the woman should be of reproductive age. With this study, we aimed to evaluate clinical and socioeconomic characteristics in women with CIN2 managed by active surveillance or large loop excision of the transformation zone (LLETZ) and to evaluate temporal changes in the clinical management of CIN2. MATERIAL AND METHODS: We conducted a Danish nationwide study using data from healthcare registries. All female residents aged 18-40 years, diagnosed with incident CIN2 from January 1, 1998, to February 29, 2020, were included. We collected data on age, index cytology result, year of CIN2 diagnosis, region of residence, civil status, HPV vaccination status, and socioeconomic position indicators. The variables were tabulated overall and by management group (active surveillance vs. LLETZ). To evaluate time trends, we used joinpoint regression to calculate the annual percentage change (APC), including 95% confidence intervals (CI). RESULTS: Of the 27 536 women with CIN2 included, 12 500 (45.4%) underwent active surveillance, and 15 036 (54.6%) underwent a LLETZ. Women undergoing active surveillance were younger, more often HPV-vaccinated, and more likely to have a normal/low-grade index cytology result than women undergoing LLETZ. Socioeconomic position indicators did not differ. Over time, the proportion of women undergoing active surveillance increased from 21.7% in 2004 to 73.6% in 2019 (APC 9.7, 95% CI 8.1-11.4). The proportion of women undergoing active surveillance aged <30 declined over time (APC -2.2, 95% CI -2.9 to -1.5). The proportion of women with normal/low-grade index cytology increased slightly to 51.6% in 2019 (APC 0.8, 95% CI 0.4-1.3). CONCLUSIONS: The use of active surveillance for CIN2 has increased over the past two decades in Denmark. Observed differences in characteristics between women undergoing active surveillance vs LLETZ are likely related to indications for clinical management.
