Socioeconomic status and incident depressive symptoms among older adults: A 3-year longitudinal study from the Japan Gerontological Evaluation Study.

The association between socioeconomic status (SES) and the onset of depressive symptoms has attracted considerable attention. However, few studies have simultaneously examined the association of multiple SES indicators, including "assets," with the onset of depressive symptoms. Therefore, this study examined the association of four SES indicators in old age ('years of education' 'equivalent income,' 'equivalent assets,' and 'the longest-held job') with new-onset depressive symptoms in a large Japanese dataset. This longitudinal study used panel data of cognitively and physically independent older adults from the Japan Gerontological Evaluation Study (JAGES) conducted in 2013 and 2016. Multivariate logistic regression analysis was conducted to examine the association of each SES indicator with new-onset depressive symptoms, and odds ratios and 95% confidence intervals (CIs) were calculated. We analyzed the data of 40,257 older adults, with a mean age (± standard deviation) of 72.9 (±5.5) years. In the follow-up survey, 4292 older adults had new-onset depression symptoms (10.7%). 39.3% had 10-12years of education. 36.9% had an equivalent income of up to JPY 1.99 million. 24.4% had equivalent assets of JPY 4-17.99 million. Most had a clerical job for the long time. Furthermore, fewer years of education (males: OR=1.42, 95% CI=1.22-1.64, p-value <0.001/females: 1.26, [1.09-1.47], p=0.002), lower income (males: 1.64, [1.34-2.01], p<0.001/females: 1.82, [1.49-2.22], p<0.001), and fewer assets (males: 1.40, [1.16-1.68], p<0.001/females: 1.21, [1.02-1.42], p=0.025) resulted in higher odds of having new-onset depressive symptoms, even when other SES indicators were entered simultaneously. All four SES indicators have an independent association with the development of new-onset depressive symptoms among older adults, reflecting different aspects of SES. The association between the "longest-held job" and new-onset depressive symptoms can be largely explained by other SES indicators. A multifaceted and lifetime approach is required to prevent the onset of depressive symptoms in old age.

Decomposition of socioeconomic inequalities in glaucoma knowledge in Taiwan.

Glaucoma knowledge is strongly associated with medication adherence and preventive behavior. Studies have frequently reported socioeconomic inequalities in glaucoma knowledge. This study aimed to decompose such inequalities. Decomposition analysis enables the design of policies directly targeting the underlying causes of inequality. We performed a cross-sectional survey from January 1, 2019 to June 30, 2019, at the departments of ophthalmology of 2 medical centers belonging to a hospital chain in northern Taiwan. Socioeconomic inequalities in glaucoma knowledge were ranked based on 3 aspects of socioeconomic status (SES): (1) education, (2) income, and (3) self-perceived financial status. The concentration index was calculated and decomposed using decomposition analysis. Elasticity and marginal effects were estimated for each decomposed factor. In total, 1,203 patients completed the survey. Both measures of glaucoma knowledge and overall glaucoma knowledge score significantly contributed to the progressivity of knowledge inequalities (pro-high-SES inequalities). The concentration index for overall knowledge score with respect to education was 0.166 (p<0.001). Both objective and subjective measures of SES were associated with pro-high-SES inequalities. Our decomposition analysis revealed that demographic factors and attitudinal factors such as the level of concern regarding developing glaucoma contributed significantly to SES-based inequalities in glaucoma knowledge. Our decomposition analysis provided empirical evidence regarding the underlying causes of SES-based inequalities in glaucoma knowledge. Efforts to improve glaucoma knowledge should consider specific factors that drive SES-based inequalities, such as age, sex, and concern about vision health, to ultimately achieve low SES-based inequalities.

Development and validation of the Socioeconomic Status Composite Scale (SES-C).

Socioeconomic status (SES) is a critical multifactorial determinant of health and plays a significant role in shaping an individual's health outcomes. While a composite scale has been proposed to measure SES in children, to our knowledge, limited composite scales were developed for adults in different contexts, highlighting the need for a comprehensive and valid SES measure to elucidate the relationship between SES and health in this population. This study aimed to develop and validate a composite scale that measures the socioeconomic status in Lebanon and assess its correlates in a socioeconomic crisis context. An online study was carried out between October and November 2022 across all Lebanese regions. Snowball sampling was used to enroll 448 adults living in Lebanon through a questionnaire created on Google Forms and shared by WhatsApp to a first sample from all geographic areas. The developed composite scale (SES-C) was found to be reliable and valid. It was based on several aspects of socioeconomic status, i.e., participant education level, family head education level, perceived social class, not being in debt, not receiving financial help, crowding index, participant work status, family head work status, monthly household income, and financial well-being. Furthermore, high SES was significantly associated with married status, older age, alcohol consumption, the absence of chronic disease, easy access to healthcare, private insurance coverage, and the number of rooms in the house in the bivariate analysis. In the multivariable analysis, high SES was significantly associated with age (ORa-1.13; p = 0.011) and easy access to healthcare (ORa = 7.81; p = 0.001) and inversely associated with chronic disease (ORa = 0.17; p = 0.002). Similar results with lower magnitude were found for moderate SES. The study successfully developed and validated a composite scale (SES-C) for measuring the socioeconomic status in Lebanon, taking into account the complexities of the Lebanese context. The scale was found to be reliable and valid, and its results showed significant correlations with various factors such as older age, lower risk of chronic disease, and easy access to healthcare.

AGING IN CROSS-NATIONAL CONTEXTS

Abstract Cross-national comparative research is a useful tool for identifying common aspects of, and risk factors for, healthy and unhealthy aging across populations and sociocultural contexts. The papers in this symposium use harmonized data from the Gateway to Global Aging to examine a range of topics in aging and provide new insights into long-standing and emerging questions in aging research. Using data on 31 countries, Ehrlich estimates the population attributable fraction of dementia due to vision impairment, a treatable and thus potentially viable target for interventions to slow progression to dementia. Seligman et al., use a frailty index validated in multiple countries to provide new evidence for which aspects of socioeconomic status (SES) – education, income, rural residence – are most strongly linked to frailty in Brazil, China, and India, three highly populated and rapidly aging countries. Using recent harmonized data on stress, Chen et al. examine the association between cumulative social stressors and cognitive function trajectories in the US and UK, finding interesting patterns in the relationship with status and change over time. Finally, several harmonized aging studies collected data throughout the COVID-19 pandemic, and Mair et al., take advantage of this to gain insights into how family structure impacted experiences of loneliness among older adults during the pandemic in the U.S. and across Europe. The papers in this symposium demonstrate the tremendous potential for using cross-national comparisons to deepen our understanding of health and well-being among older adults.

Assessment of Parent Income and Education, Neighborhood Disadvantage, and Child Brain Structure

Although different aspects of socioeconomic status (SES) may represent distinct risk factors for poor mental health in children, knowledge of their differential and synergistic associations with the brain is limited. To examine the independent associations between distinct SES factors and child brain structure. We used baseline data from participants aged 9 to 10 years in the Adolescent Brain Cognitive Development (ABCD) study. These data were collected from 21 US sites between September 2017 and August 2018. Study participants were recruited from schools to create a participant sample that closely reflects the US population. Neighborhood disadvantage was measured using the area deprivation index. We also used data on total parent or caregiver educational attainment (in years) and household income-to-needs ratio. T1-weighted magnetic resonance imaging was used to assess measures of cortical thickness, surface area, and subcortical volume. Data from 8862 ABCD participants aged 9 to 10 years were analyzed. The mean (SD) age was 119.1 (7.5) months; there were 4243 girls (47.9%) and 4619 boys (52.1%). Data on race or ethnicity were available for 8857 of 8862 participants: 173 (2.0%) were Asian, 1099 (12.4%) were Black or African American, 1688 (19.1%) were Hispanic, 4967 (56.1%) were White, and 930 (10.5%) reported multiple races or ethnicities. Using 10-fold, within-sample split-half replication, we found that neighborhood disadvantage was associated with lower cortical thickness in the following brain regions (η2 = 0.004-0.009): cuneus (B [SE] = -0.099 [0.013]; P < .001), lateral occipital (B [SE] = -0.088 [0.011]; P < .001), lateral orbitofrontal (B [SE] = -0.072 [0.012]; P < .001), lingual (B [SE] = -0.104 [0.012]; P < .001), paracentral (B [SE] = -0.086 [0.012]; P < .001), pericalcarine (B [SE] = -0.077 [0.012]; P < .001), postcentral (B [SE] = -0.069 [0.012]; P < .001), precentral (B [SE] = -0.059 [0.011]; P < .001), rostral middle frontal (B [SE] = -0.076 [0.011]; P < .001), and superior parietal (B [SE] = -0.060 [0.011]; P < .001). Exploratory analyses showed that the associations of low educational attainment or neighborhood disadvantage and low cortical thickness were attenuated in the presence of a high income-to-needs ratio (η2 = 0.003-0.007). The findings of this cross-sectional study suggest that different SES indicators have distinct associations with children's brain structure. A high income-to-needs ratio may play a protective role in the context of neighborhood disadvantage and low parent or caregiver educational attainment. This study highlights the importance of considering the joint associations of different SES indicators in future work.

The associations of socioeconomic status and financial strain with restrained and emotional eating among 42-year-old women and men

The current study investigated how different aspects of socioeconomic status (SES) and experiencing financial strain are associated with restrained and emotional eating among 42-year-old Finnish women and men. Lower SES is shown to be associated with diets of poorer nutritional quality and obesity. Nevertheless, little research has been done on the association between SES, financial strain and psychological dimensions of eating behaviour. The study was based on questionnaire data from 734 women and 600 men aged 42 years who were participants in a Finnish cohort study.SES was measured through three different dimensions: education, occupation and household income. Data were analyzed using binary logistic regression models.Results showed that restrained eating was associated with higher household income level in women and with higher occupational position in men. Emotional eating was associated with higher financial strain among women. Also, women with lower college education had higher odds for emotional eating compared to women with vocational education or less. Among men, emotional eating was not statistically significantly associated with any of the SES variables nor with financial strain, which may also be due to the very low level of emotional eating reported by men. In conclusion, our findings indicate that restrained eating would be associated with higher status brought by belonging to a higher income or occupational group. Emotional eating, in turn, would be related to experiencing financial strain, rather than to traditional SES dimensions, in women. These results are relevant when health-related interventions are targeted to different SES groups.

Educational inequalities and school segregation. Social cohesion challenges faced by public schools in the local educational system

Challenges that schools face in relation to social cohesion include the need to minimise the impact of students’ social background on their educational career and ensuring that the public school is a place of contact between children from different social groups and class. Research supporting local policy in this area should therefore monitor the social status-based determinants of students’ educational careers and other processes of intentional as well as spontaneous between school and between classroom segregation. The following facts were found in the local educational system analysed. The measures of SES dimensions of students’ family are significantly related to their school achievement. In Ostrołęka, this connection was found to be considerably stronger than the national average. However, which is certainly an optimistic result, the financial resources of the students’ families, with other SES dimensions controlled, did not affect school achievement. Parents’ educational aspirations for their children, on the other hand, are related to all aspects of socio-economic status. In this case, also the financial capacity of the students’ families is significantly related to the level of these aspirations. Including students’ school grades along with the SES dimensions in the analysis of the determinants of educational aspirations shows that they determine aspirations to the same degree as family status does. Sadly, there is no evidence that pre-school education helps low SES students catch up with their peers with high SES families. This means that the key to effectively support the development of children from educationally at-risk backgrounds is in the quality of preschool education and not just its universality. Schools in Ostrołęka differ in their social composition in terms of the parents’ education status and the financial capacity of their families, but the scale of these differences is not considerable. On the other hand, between classroom within school differentiation due to parents’ social status is in some schools much stronger than inter-school differences, which poses a serious problem.

Longitudinal Associations Between Parental SES and Adolescent Health-Related Quality of Life Using Growth Curve Modeling

We evaluate how two aspects of socioeconomic status, parental objective and subjective social status, are associated with health-related quality of life in three racial/ethnic groups during pre- to mid-adolescent development, using growth curve modeling. In a longitudinal cohort study, 4,048 Black, Latinx, or White adolescents were assessed in 5th, 7th and 10th grade. Objective social status (OSS) was based on parent-reported highest household educational attainment and total household income, and subjective social status (SSS) was measured with the MacArthur Scale, through which parents indicated their social standing in reference to community and national norms. Adolescents completed the Pediatric Quality of Life Inventory to measure their physical and psychosocial health-related quality of life. Based on growth curve modeling of the intercept, adolescents whose parents have higher OSS levels reported better health-related quality of life, whereas parental SSS was not associated with adolescent health-related quality of life in 5th grade. These findings were largely consistent across racial/ethnic groups. Based on growth curve modeling of the developmental slopes (or growth curves), higher objective social status was associated with a slower positive growth of health-related quality of life from 5th to 10th grade, which was largely consistent across racial/ethnic groups. The opposite appeared for parental SSS and physical health-related quality of life, and only for Latinx, where higher parental perceived social status was associated with an acceleration of positive change. Family income and education may influence health-related quality of life at the start of adolescence, but its effect appears to diminish as youth mature. However, in Latinx youth, parents’ perceived social status may continue to influence improvement in their physical health-related quality of life as they mature.

The Relation between Parents’ Child-Rearing Behavior and Their Socioeconomic Status in a Developing Country Context: A Case from West Bengal, India

This study examines variation in parents’ child-rearing behavior based on their socioeconomic status (SES) in the context of a developing country. The impact of different aspects of SES on the probability of practicing several child-rearing behaviors was examined individually based on a data of 1373 households in West Bengal, India. The study found that components of SES explain great shares of the variance in parents’ child-rearing behaviors and the variation was bi-dimensional. There was variation between parental practices due to a change in SES, and also each practice was affected differently for each component of SES. Mother’s level of education was found to play a consistent and most significant role in improving parent-child regular interaction.

Education, Smoking and CRP Genetics in Relation to C-Reactive Protein Concentrations in Black South Africans.

Because elevated circulating C-reactive protein (CRP) and low socio-economic status (SES), have both been implicated in cardiovascular disease development, we investigated whether SES factors associate with and interact with CRP polymorphisms in relation to the phenotype. Included in the study were 1569 black South Africans for whom CRP concentrations, 12 CRP single nucleotide polymorphisms (SNPs), cardiovascular health markers, and SES factors were known. None of the investigated SES aspects was found to associate with CRP concentrations when measured individually; however, in adjusted analyses, attaining twelve or more years of formal education resulted in a hypothetically predicted 18.9% lower CRP concentration. We also present the first evidence that active smokers with a C-allele at rs3093068 are at an increased risk of presenting with elevated CRP concentrations. Apart from education level, most SES factors on their own are not associated with the elevated CRP phenotype observed in black South Africans. However, these factors may collectively with other environmental, genetic, and behavioral aspects such as smoking, contribute to the elevated inflammation levels observed in this population. The gene-smoking status interaction in relation to inflammation observed here is of interest and if replicated could be used in at-risk individuals to serve as an additional motivation to quit.

Socioeconomic inequalities in cancer incidence in Europe: a comprehensive review of population-based epidemiological studies

BackgroundSince the end of the previous century, there has not been a comprehensive review of European studies on socioeconomic inequality in cancer incidence. In view of recent advances in data source linkage and analytical methods, we aimed to update the knowledge base on associations between location-specific cancer incidence and individual or area-level measures of socio-economic status (SES) among European adults.Materials and methodsWe systematically searched three databases (PubMed, Scopus and Web of Science) for articles on cancer incidence and SES. Qualitative synthesis was performed on the 91 included English language studies, published between 2000 and 2019 in Europe, which focused on adults, relied on cancer registry data and reported on relative risk (RR) estimates.ResultsAdults with low SES have increased risk of head and neck, oesophagogastric, liver and gallbladder, pancreatic, lung, kidney, bladder, penile and cervical cancers (highest RRs for lung, head and neck, stomach and cervix). Conversely, high SES is linked with increased risk of thyroid, breast, prostate and skin cancers. Central nervous system and haematological cancers are not associated with SES. The positive gap in testicular cancer has narrowed, while colorectal cancer shows a varying pattern in different countries. Negative associations are generally stronger for men compared to women.ConclusionsIn Europe, cancers in almost all common locations are associated with SES and the inequalities can be explained to a varying degree by known life-style related factors, most notably smoking. Independent effects of many individual and area SES measures which capture different aspects of SES can also be observed.

Development of narrative macrostructure in monolingual preschoolers in Germany and impact of socio-economic status and home literacy environment

The aim of this paper is to analyse the development of narrative macrostructure and the impact of socio-economic status (SES) and home literacy environment (HLE) on the narrative macrostructure of monolingual preschoolers in Germany when retelling and telling a story. The analysis of narrative macrostructure includes three components: story structure, story complexity, and story comprehension. Oral narratives were elicited via Multilingual Assessment Instrument for Narratives (LITMUS-MAIN). 198 monolingual children between age 4;6 and 5;11 participated (M=63 months, SD=5 months). The comparison of narrative macrostructure in three age groups (4;6 to 4;11 years, 5;0 to 5;5 years, 5;6 to 5;11 years) illustrate significant age effects in story structure, story complexity and story comprehension skills. There were weak significant positive correlations of some of these skills with aspects of socio-economic status and home literacy environment, for example between story comprehension skills and the educational background, the frequency and duration of the child’s exposure to books and the number of books in the household.&#x0D;

Outcomes of non-metastatic colon cancer patients in relationship to socioeconomic status: an analysis of SEER census tract-level socioeconomic database.

To evaluate the outcomes of non-metastatic colon cancer patients in relation to the socioeconomic status (SES) at diagnosis based on the Surveillance, Epidemiology, and End Results (SEER) census tract level-SES database. SEER SES census tract level database represents a specially designed database to integrate different aspects of SES among cancer patients. It reports a composite SES index for each patient. Patients were then stratified into three SES groups. Patients with a non-metastatic colon cancer diagnosis, diagnosed (2004-2015), and who were included in this specialized database were included in the current study. Multivariate Cox regression analysis was used to assess the impact of SES index on colon cancer-specific survival. A total of 80,121 patients with non-metastatic colon cancer were included in the current study. Comparing patients in the lower SES group with patients in the higher SES group, patients with lower SES were more likely to have a younger age at presentation (P < 0.001), black race (P < 0.001) and more advanced stage at presentation (P < 0.001). The impact of the SES on colon cancer-specific survival was evaluated through multivariate Cox regression analysis adjusted for age, sex, race, stage, and colon cancer side. Lower SES was associated with worse colon cancer-specific survival (hazard ratio for group 1 versus group 3: 1.257; 1.190-1.328; P < 0.001). Interaction testing between race (black race versus white race) and SES was non-significant (P = 0.932). Lower SES is associated with worse colon cancer-specific survival among non-metastatic colon cancer patients.

A Survey on BDSM-related Activities: BDSM Experience Correlates with Age of First Exposure, Interest Profile, and Role Identity

BDSM is an omnibus term covering a spectrum of activities within bondage/discipline, dominance/submission, and sadism/masochism relationships. To date, BDSM practitioners experience stigma due to a general unfamiliarity with the practice and marginalization of this type of sexual behavior. Destigmatization occurs partly through knowledge expansion and identification with the stigmatized group. In this study within the Belgian population, we aimed to characterize certain aspects of socioeconomic status and specific BDSM preferences of individuals with differing BDSM experience levels. We show that individuals who perform BDSM in a community setting (BDSM clubs, events. BDSM-CP) are generally higher educated, are significantly younger when first becoming aware of their inclination toward kink-oriented sex, and have a more strict BDSM role identity (Dom vs. Sub) than individuals who engage in BDSM-related activities in a private setting (BDSM-PP). This latter group in turn display a more pronounced Dom/Sub identification than individuals who only fantasize about the practice (BDSM-F). Our data indicate BDSM interest is a sexual preference already manifesting at early age, with role identification profiles becoming gradually more pronounced based on the practitioner’s contextual experience.

How does education lead to healthier behaviours? Testing the mediational roles of perceived control, health literacy and social support

Objectives: Educational attainment is increasingly recognised as a unique dimension of socioeconomic status (SES) and a powerful determinant of health behaviour—and thus physical health and mortality. However, very little is known about the specific pathways through which education influences these health behaviours. Design: The present study used a nationally representative US survey to test three potential psychosocial pathways (perceived control, health literacy and social support) through which education might influence intake of fruits and vegetables (FV), physical activity (PA) and sedentary behaviour (SB), controlling for other aspects of SES (income, health insurance status) and demographics (age, gender, race/ethnicity). Results: Both aspects of perceived control (locus of control, cancer fatalism) mediated the impact of education on FV and PA while only locus of control mediated the impact of education on SB. Further, only one aspect of health literacy (ability to understand recommendations) mediated education’s effect on any health behaviour (FV). Social support did not mediate any of the effects of education on health behaviors. Conclusion: Future work explicitly assessing and testing these mediational pathways is needed to better understand how education influences people’s health behaviours throughout their lives.

Low socioeconomic status increases effects of negative life events on antenatal anxiety and depression

ProblemLow socioeconomic status and prior negative life events are documented risk factors for antenatal anxiety and depression, preterm birth and birth weight. We aimed to asses whether the adverse effects of prior negative life events increase with lower socioeconomic status and which aspects of socioeconomic status are most relevant. MethodsWe performed a population-based cohort study in the Netherlands including 5398 women in their first trimester of pregnancy. We assessed the number of negative life events prior to pregnancy, aspects of paternal and maternal socio-economic position and symptoms of anxiety and depression. Associations of the number of prior negative life events with anxiety, depression, low birth weight and gestational age were quantified. FindingsThe number of prior negative life events, particularly when they had occurred in the two years before pregnancy and maternal aspects of low socioeconomic status (educational level, unemployment and income) were associated with antenatal anxiety and depression. Furthermore, low socioeconomic status increased the adverse effects of prior negative life events. Obstetric outcomes showed similar trends, although mostly not statistically significant. DiscussionLow socioeconomic status and prior negative life events both have an adverse effect on antenatal anxiety and depression. Furthermore, low socioeconomic status increases the adverse impact of prior negative life events on anxiety and depressive symptoms in pregnancy. ConclusionInterventions for anxiety and depression during pregnancy should be targeted particularly to unemployed, less-educated or low-income women who recently experienced negative life events.

Retirement as a lens for socioeconomic differences in Cognition and well-being

This study conceptualizes retirement as a lens with regard to patterns of social inequality across the life course. It investigates if socioeconomic differences in well-being and cognitive performance differ between older workers and retirees, using data from the HEARTS (Health, Aging and Retire- ment Transitions in Sweden) study. The results provide evidence for retirement as a positive lenswith regard to cognition, following the ‘use it or lose it’ hypothesis. We also find evidence for retire- ment as a negative lens with regard to well-being, supporting the cumulative (dis-)advantages theory.We test different aspects of socioeconomic status, that is, education, income, occupationalgroup, and subjective work aspects and find the strongest effects for education. Hence, this studycontributes with an understanding of mechanisms behind social inequalities over the life-course by using retirement and the loss of the work role as a marker for potential change

Effects of socioeconomic status, health behavior, and physical activity on the prevalence of metabolic syndrome.

Routine medical checkups have been provided by both the government-led and private hospitals for the purposes of prevention and early detection of diseases. Various studies were conducted with clinical results obtained from both government and private hospital based results. However, results from two types of health checkups have not been conducted. The results should be compared for the prevalence of metabolic disease in the aspects of socioeconomic status and health care behaviors to observe the pros and cons of two types of health checkups. Routine health checkup results of the National Health and Nutrition Survey (1,593 men, 2,180 women) and a private hospital (12,823 men, 7,070 women) of the year 2012 were used for the study. Education level and monthly household income were used to assess the socioeconomic status. Alcohol consumption, smoking, and International Physical Activity Questionnaire were used to assess health behaviors. Logistic regression analysis was applied (P<0.05). Participants of the private hospital had significantly greater household income, education level, amount of physical activity and intensity, and number of nonsmokers. Women showed no differences in the amount of vigorous physical activity. The prevalence rates of metabolic syndrome showed similar results. Education level, physical activity, and alcohol consumption were significantly associated in men of the government group. Smoking showed significant influence in men of both groups. Education level, alcohol consumption, and smoking showed significant influence in women of the government group. Participants who conducted government-led health examinations showed stronger influence of socioeconomic level and health behaviors on metabolic syndrome especially in men.

Social Causation Versus Health Selection in the Life Course: Does Their Relative Importance Differ by Dimension of SES?

A person’s socioeconomic status (SES) can affect health (social causation) and health can affect SES (health selection). The findings for each of these pathways may depend on how SES is measured. We study (1) whether social causation or health selection is more important for overall health inequalities, (2) whether this differs between stages of the life course, and (3) between measures of SES. Using retrospective survey data from 10 European countries (SHARELIFE, n = 18,734), and structural equation models in a cross-lagged panel design, we determine the relative explanatory power of social causation and health selection through childhood, adulthood, and old age. We use three ways to measure SES: First, as a latent variable capturing different aspects of SES, second as material wealth, and third as occupational skill level. Between childhood and adulthood, social causation and health selection are equally important. In the transition from adulthood to old age, social causation becomes more important than health selection, making it the dominant mechanism in old age. The three measures of SES produce similar results. Only material wealth shows a stronger effect on health (between childhood and adulthood); it is also more affected by health (between adulthood and old age) than the other measures.

Socioeconomic disparities in academic achievement: A multi-modal investigation of neural mechanisms in children and adolescents

Growing evidence suggests that childhood socioeconomic status (SES) influences neural development, which may contribute to the well-documented SES-related disparities in academic achievement. However, the particular aspects of SES that impact neural structure and function are not well understood. Here, we investigate associations of childhood SES and a potential mechanism—degree of cognitive stimulation in the home environment—with cortical structure, white matter microstructure, and neural function during a working memory (WM) task across development. Analyses included 53 youths (age 6–19 years). Higher SES as reflected in the income-to-needs ratio was associated with higher parent-reported achievement, WM performance, and cognitive stimulation in the home environment. Although SES was not significantly associated with cortical thickness, children raised in more cognitively stimulating environments had thicker cortex in the frontoparietal network and cognitive stimulation mediated the assocation between SES and cortical thickness in the frontoparietal network. Higher family SES was associated with white matter microstructure and neural activation in the frontoparietal network during a WM task, including greater fractional anisotropy (FA) in the right and left superior longitudinal fasciculi (SLF), and greater BOLD activation in multiple regions of the prefrontal cortex during WM encoding and maintenance. Greater FA and activation in these regions was associated higher parent-reported achievement. Together, cognitive stimulation, WM performance, FA in the SLF, and prefrontal activation during WM encoding and maintenance significantly mediated the association between SES and parent-reported achievement. These findings highlight potential neural, cognitive, and environmental mechanisms linking SES with academic achievement and suggest that enhancing cognitive stimulation in the home environment might be one effective strategy for reducing SES-related disparities in academic outcomes.
