Mind over matter. The impact of subjective social status on health outcomes and health behaviors

Contributions of subjective status to eating behaviors, obesity, and metabolic health across development

Subjective status is the evaluation of one's social or socioeconomic status relative to others. Lower subjective status has been associated with risk of overweight/obesity, poorer metabolic health, and obesogenic food preferences and eating behaviors. However, these findings are predominantly based on studies of adolescents and young adults. This indicates major gaps in knowledge and application of this social determinant of obesity and metabolic health, given that perceived status develops throughout the life course along with food environments and eating habits. Here, we review the relationships that subjective status shares with the outcomes of eating behaviors, obesity, and metabolic health across milestones and periods of development: during the prenatal period, as caregivers who feed children, during childhood (prior to age 10) and from adolescence into emerging adulthood (until mid-20's). For each developmental period, we explore why the period critically contributes to these outcomes and how subjective status may affect eating behaviors and metabolic health. We propose that subjective status contributes to eating/feeding behaviors and metabolic health both within and across developmental periods, such that the effect of low subjective status at an earlier period may contribute to obesogenic eating behaviors and metabolic health in later developmental periods and intergenerationally. The influence of low subjective status on higher body weight may also threaten subjective status later in development through heightened vulnerability to social stressors, such as weight-based stigma. Overall, subjective status may be a broadly influential factor to consider when examining social determinants of obesity and metabolic health across development.

Understanding the mechanisms underlying the socioeconomic disparities in cancer screening among Australian women

BACKGROUND

Little is known about individual, as opposed to area-level, variance in socioeconomic status (SES) and how this impacts screening participation. This study explores potential mechanisms underlying the relationship between SES and cancer screening amongst women eligible for breast, cervical, and bowel cancer screening.

METHODS

Australian women aged 50-74 years (N = 874) took part in an online survey examining participants' health and cancer screening behaviours. Relationships between individual and area-level SES, cancer screening participation, stress, general self-efficacy, and screening literacy were examined using structural equation modelling. Frequency of cancer screening barriers were calculated for each cancer type and compared for SES categories.

RESULTS

The structural equation model including stress and screening literacy as mediators yielded excellent fit, χ2 (26) = 33.322, p = .153, TLI = 0.992. Lower individual level SES was associated with higher stress and lower screening literacy. Higher stress was related to lower screening participation in all three programs, and lower screening literacy was associated with low cervical and breast cancer screening. The only significant relationship between area-level SES and screening participation was with participation in cervical screening. All indirect effects between area level SES and screening were non-significant. The types of barriers reported for each cancer screening type were similar between high and low socioeconomic individuals. In all three screening programs, intending to participate in cancer screening but not getting around to it, and not liking the screening method were commonly reported reasons for non-participation.

CONCLUSIONS

This study is the first to investigate the effects of individual level SES on cancer screening in Australia and one of the few studies to examine underlying mechanisms simultaneously across various screening programs. Reducing stress and improving screening literacy may help to improve cancer screening participation among low SES individuals. Our results also suggest that tailoring interventions to the SES background of women may not enhance their effectiveness. Interventions aiming to reduce the SES screening disparities may achieve more success through addressing underlying mechanisms as opposed to the behavioural barriers themselves.

Subjective social status and trajectories of frailty: findings from the English Longitudinal Study of Ageing

Objectives

Subjective social status is a known antecedent for many health outcomes, but little research has examined the association between subjective status and frailty among older people. Using longitudinal data, the goal of this study was, first, to identify latent trajectories of frailty over time, and second, to investigate the relationship between subjective social status and frailty trajectory.

Methods

Data were drawn from the 2002-2019 surveys of the English Longitudinal Study of Ageing, involving 9484 individuals aged 50+ years at baseline. Group-based trajectory models were used to identify frailty trajectories over the 18-year period, and multinomial regression models were used to investigate the relationship between subjective social status and frailty trajectory membership. Controls were included for confounding factors, including a range of socioeconomic indicators and health behaviours.

Results

Four trajectories of the frailty index were retained: low frailty (53% of participants), progressive mild frailty (25%), progressive moderate frailty (15%) and high frailty (6%). Higher subjective social status is associated with higher probabilities of being in the low-frailty group and lower probabilities of being in one of the progressive or high-frailty groups.

Conclusions

Subjective social status is significantly associated with being in a milder frailty trajectory after controlling for age, health behaviours and a wide range of objective socioeconomic status markers.

Association between subjective social status and physical frailty in older adults in India: perceived discrimination and III-treatment as mediators and moderators

BACKGROUND

While extensive research exists on physical frailty, including in low- and middle-income countries like India, studies have yet to appraise whether perceived social standing is associated with physical frailty. As such, this study examines (1) the association between subjective social status (SSS) and physical frailty among older adults in India; and (2) whether this association is mediated and moderated by perceived discrimination and experiences of III-treatment.

METHODS

Data came from the Longitudinal Aging Study in India with a sample of 31,464 older adults aged 60 and above. Physical frailty was assessed using an adapted version of the frailty phenotype developed by Fried and colleagues. SSS was assessed using the Macarthur scale. Multivariable logistic regression models along with Karlson-Holm-Breen (KHB) methodology were employed to examine the direct association, mediational pathways, and the interactions.

RESULTS

The prevalence of frailty was 30.65% and those with lowest SSS reported higher prevalence of frailty (42.06%). After adjusting for several confounders, odds of frailty were lower among persons with high SSS relative to those with low SSS, and the variance explained by the SSS was higher than that explained by household consumption quintiles. Moreover, the association between SSS and frailty was mediated and moderated by perceived discrimination and III-treatment.

CONCLUSIONS

Our findings underscore that when examining the association between socioeconomic status (SES) and physical frailty, it is important to consider SSS given that perceived social status likely reflects the less apparent psychosocial components associated with SES, and that perceived discrimination and III-treatment both mediate and moderate the association between SSS and physical frailty is critical to identifying those older Indians most susceptible to the functional health implications of lower SSS.

Subjective social status and functional and mobility impairments among older adults: life satisfaction and depression as mediators and moderators

BACKGROUND

While functional and mobility impairments (FMIs) have garnered the attention of health researchers in low and middle-income countries (LMICs), including India, research has yet to explore whether and to what extent the perception of one's social status is associated with FMIs. We fill this gap in the literature by examining (1) the association between subjective social status (SSS) and FMIs among older adults in India and (2) whether this association between SSS and FMIs is mediated and moderated by life satisfaction and depression.

METHODS

Data come from the 2017-18 wave 1 of the Longitudinal Aging Study in India (LASI) with a sample of 31,464 older adults aged 60 years and above. FMIs were assessed using established scales on impairments in activities of daily living (ADLs), instrumental activities of daily living (IADLs), and mobility. SSS was assessed using the Macarthur scale. Life satisfaction was measured using responses to five statements gauging respondent's overall satisfaction with life. Depression was calculated using the shortened version of the Composite International Diagnostic Interview (CIDI-SF). Multivariable regression was employed to examine the association between variables, and the interaction terms and Karlson-Holm-Breen (KHB) method were used separately to test the mediation and moderation effects.

RESULTS

39.11% of the sample had a low SSS, 8.26% were depressed, and 32.07% reported low life satisfaction. A total of 8.74%, 10.91%, and 8.45% of the study population reported at least one impairment in ADL, IADL, and mobility, respectively. Older adults in the higher SSS group were less likely to have ADL impairment (beta: -0.017, CI: -0.030, -0.0032) and mobility impairment (beta: -0.044, CI: -0.076, -0.013). Depression moderated the association between SSS and mobility impairment (p-value: 0.025), and life satisfaction moderated the association between SSS and ADL impairments (p-value: 0.041) and SSS and IADL impairments (p-value: 0.037). Depression mediated 20.28%, 31.88%, and 18.39% of the associations of SSS with ADL, IADL, and mobility impairments, respectively. Similarly, life satisfaction mediated 23.24%, 52.69%, and 27.22% of the associations of SSS with ADL, IADL, and mobility impairments.

CONCLUSIONS

That SSS is associated with FMIs among older Indians, even after considering their objective socioeconomic status (SES), suggests that the use of SSS is relevant to the study of health inequalities in India. The finding that life satisfaction and depression mediate and moderate this association is crucial in pinpointing those older Indians at risk of the functional and mobility-related repercussions of lower SSS.

Subjective social status, race, and metabolic syndrome in women with breast cancer

PURPOSE

To evaluate the association of subjective social status (SSS) with metabolic syndrome (MetS) severity and its potential contribution to racial health disparities in women with breast cancer.

METHODS

Multicenter cross-sectional study (10 US hospitals) in women (n = 1206) with primary diagnosis of invasive breast cancer received during Mar/2013-Feb/2020. Participants, self-identified as non-Hispanic White or Black, underwent physical and laboratory examinations and survey questions assessing socioeconomic parameters, medical history, and behavioral risks. SSS was measured with the 10-rung MacArthur scale. MetS severity was measured with a validated Z-Score. Generalized linear mixed modeling was used to analyze the associations. Missing data were handled using multiple imputation.

RESULTS

Average age was 58 years. On average, the SSS of Black women, given equivalent level of income and education, was lower than the SSS of White women: 6.6 (6.1-7.0) vs 7.7 (7.54-7.79) among college graduates and 6.8 (6.4-7.2) vs 7.6 (7.5-7.8) among women in the high-income category (> $75,000). In multivariable analysis, after controlling for age, income, education, diet, and physical activity, increasing SSS was associated with a decrease in MetS-Z score, - 0.10 (- 0.16 to - 0.04) per every 2 rung increase in the MacArthur scale.

CONCLUSION

Black women with breast cancer rank their SSS lower than White women with breast cancer do at each level of income and education. As SSS is strongly associated with MetS severity these results identify potentially modifiable factors that contribute to racial disparities.

Perceived Scarcity Across Sociodemographic Backgrounds Predicts Self-Reported Health

Abstract. Background: Perceived scarcity shows promise as an indicator of physical and mental health and a possible predictor of health disparities; however, a systematic investigation of how perceived scarcity is experienced across racial and ethnic, gender, and socioeconomic groups is imperative. Moreover, it is necessary to unpack the unique predictive power of each scarcity domain. Aims: First, differences in the experience of perceived scarcity by various sociodemographic groups in overall perceived scarcity and each of its three dimensions were explored using a cross-sectional sample. Next, using self-reported health outcome data collected from participants at a second time point, the direct and mediating role of perceived scarcity in the relationship between sociodemographic indicators and self-reported health was examined. Method: Participants included a racially and socioeconomically diverse online sample. One-way analyses of variance (ANOVAs) and t-tests were used to assess whether perceived scarcity, overall and by domain, varied by sociodemographic factors. PROCESS macro for SPSS v 3.5 was used to analyze the proposed direct effects and mediations. Results: Results indicate that sociodemographic differences do exist in perceived scarcity and in a variety of ways that may not be reflected when solely examining overall perceived scarcity. Dimensions of perceived scarcity were found to mediate the relationship between some sociodemographic factors and self-reported health. Limitations: Future research should address the limitations of the current study’s sample insofar as recruiting a wider sample of participants to include those experiencing the most extreme forms of scarcity. Conclusion: Findings support the importance of considering the unique experience of perceived scarcity by domain across sociodemographic groups when using it as a predictor or mediator of health.

Stress Mediates the Association Between Pain and Alcohol Use in College Students

Background

Alcohol use in young adults is highly prevalent and associated with numerous consequences, including academic difficulties and motor vehicle accidents. Pain is one factor that has been increasingly shown to be associated with higher rates of alcohol consumption and riskier patterns of drinking among undergraduate students. Although pain has traditionally been viewed as a lesser concern for young adults, current research demonstrates that pain may be more prevalent in younger populations than originally thought. However, little is known about how common psychosocial factors, such as stress and subjective social status (SSS), influence the association between pain and alcohol consumption in college students.

Objective

The study's goal was to examine the effect of stress and SSS on the relationship between pain and alcohol consumption.

Participants and Methods

Participants (N = 445, 39.3% women, Mage = 22.98) were 18- to 25-year-old college students who completed an online questionnaire.

Results

Pain was significantly associated with total weekly alcohol consumption (r(445) = .22, p < 0.001); this association was significantly mediated by stress (b = 0.15, SE = 0.04, 95% CI = [.07,0.23]). SSS was significantly positively associated with alcohol consumption (r(445) = .22, p < 0.001) but was not found to significantly moderate the relationship between stress and alcohol use.

Conclusion

Results suggest that efforts to reduce college student alcohol use should include assessment of pain and stress given their association with alcohol consumption. Further, findings suggest that future studies are warranted to prospectively examine pain as an antecedent for alcohol use and to examine the utility of incorporating stress management techniques in pain-focused interventions to indirectly target alcohol use.

A protective rung on the ladder? How past and current social status shaped changes in health during COVID-19

An emerging body of work has started to document population health consequences of the social and economic transformations during the COVID-19 pandemic. We consider an individual's relative social position in the stratification system-subjective social status (SSS)-and assess how past (childhood) and current SSS predict change in self-rated health during the pandemic. Using two waves of data from the Canadian Quality of Work and Economic Life Study, we follow respondents between the onset of lockdown measures in March and May of 2020 (N = 1886). Drawing from the life course perspective and stress process model, we find that lower current SSS predicts a greater likelihood of being in stable poor health and reporting declining health. Lower past SSS predicts a higher chance of being in stable poor health indirectly through current SSS. And lower cumulative SSS that sums both past and present SSS also predicts stable poor health, while perceived upward mobility over time is associated with stable good health. This robust relationship between SSS and health in such a short time period of two months at the start of the COVID-19 pandemic provides an important glimpse into the influence that SSS has on population health.

Are stress-related pathways of social status differentiation more important determinants of health inequities in countries with higher levels of income inequality?

We explored socioeconomic gradients in self-rated overall health (SROH) using indicators of materialist (educational attainment and perceived income adequacy) and psychosocial perspectives (subjective social status (SSS)) among adults living in countries with varying levels of income inequality, and the importance of psychosocial stress in mediating these associations. If psychosocial processes at the individual and societal levels correspond, associations between SSS and SROH should be higher among adults in countries with higher income inequality, and psychosocial stress should be a more important mediator of these associations. We used multigroup structural equation models to analyse cross-sectional data from the International Food Policy Study of adults (n = 22,824) in Australia, Canada, Mexico, the UK and the United States. Associations between SSS and SROH were not higher in more unequal countries, nor was psychosocial stress a more important mediator of these associations. Inequities in SROH in more unequal countries may not predominantly reflect stress-related pathways of social status differentiation.

Sociodemographic Predictors of Adherence to National Diet and Physical Activity Guidelines at Age 5 Years: The Healthy Start Study

PURPOSE

To assess adherence to the 2015-2020 Dietary Guidelines for Americans and 2018 Physical Activity Guidelines, and identify sociodemographic predictors of adherence among children.

DESIGN

Cross sectional.

SETTING

Colorado, United States.

PARTICIPANTS

Children aged 5 (n = 482).

MEASURES

Sex, race/ethnicity, maternal education, maternal employment, maternal subjective social status and household income were assessed via questionnaires. Diet was assessed via 2 interviewer-administered 24-hour dietary recalls. Physical activity was objectively-measured with accelerometry for 7 days. Adherence was defined as a Healthy Eating Index-2015 score of ≥70 and/or ≥6 hours/day of light, moderate and vigorous activity.

ANALYSIS

For each predictor, logistic regression was used to estimate odds ratios for adherence to the diet guidelines only, the activity guidelines only or both guidelines.

RESULTS

In the full sample, 29% of children were non-adherent to both guidelines, 6% adhered to the dietary guidelines only, 50% adhered to the activity guidelines only and 14% adhered to both. Girls had a 41% lower odds of adhering to the physical activity guidelines than boys (p = 0.01), after adjustment for race/ethnicity, household income and maternal education level, perceived social status and employment status.

CONCLUSION

Efforts to improve the health of young children should promote adherence to the Dietary Guidelines for Americans among all children. Targeted interventions that increase physical activity among girls may help to mitigate health disparities.

Nursing students' perceptions of substance abusers: The effect of social status on stigma

The stigma associated with drug addiction in the U.S. has been found to be a deterrent for individuals seeking treatment (SAMHSA, 2013). This experimental vignette study examined substance abuse stigma toward a hypothetical heroin addict ("John") in a sample of 62 nursing students who were given different occupational information about John to manipulate their perceptions of his social status. Each study participant read one of three vignettes in which John was portrayed as high-status (mayor of a large city), low-status (restaurant table busser), or unspecified status (no occupational information provided). Findings indicated that high social status resulted in significantly less substance abuse stigma than low social status. There was no significant difference in substance abuse stigma between the low-status condition and the condition in which social status was unspecified. This supports the conclusion that knowledge of John's heroin addiction effectively established his social status as low. The study also showed that the fact of John's addiction alone outweighed contradictory occupational information in determining his perceived social status.

Socioeconomic position and quality of life among older people: The mediating role of social support

Social support can obscure social gradients in health, but its role as a mediator between socioeconomic position (SEP) and quality of life (QoL) in older populations remains unknown. We aimed to examine to what extent social support mediates the association between SEP and overall QoL among older adults (aged 60-84 years). We studied a population-based cohort of 585 noninstitutionalized adults in Porto, Portugal, who were evaluated in 2009. Education, occupation, and perceived income adequacy were used as SEP indicators. The WHOQOL-OLD was used to determine overall QoL. Social support was assessed using the Multidimensional Scale of Perceived Social Support. Path analysis was conducted to quantify direct, indirect, and total effects of SEP on QoL. There was a positive total effect of education on QoL (β = 0.28; 95% CI: 0.05-0.48). In this model, we found an indirect effect through social support (β = 0.15; 95% CI: 0.05-0.26), explaining 54% of the pathway between education and QoL. A similar pattern was identified for the association between occupation and QoL. Perceived income adequacy had a total effect of 2.74 (95% CI: 1.68-3.93) on QoL. Although an indirect effect through social support was found (β = 0.98; 95% CI: 0.42-1.55), a direct effect from this variable remained (β = 1.76; 95% CI: 0.65-2.90). Social support can be a mechanism through which SEP impacts the QoL of older people. Strengthening social support ties may attenuate the impact of social inequalities and improve the QoL of this population.
