Measuring the habitat as an indicator of socioeconomic position: methodology and its association with hypertension.

ABSTRACT: STUDY OBJECTIVES:(1) to develop an indicator of socioeconomic position based on the social standing of the habitat (SSH), that is, the residential building, its immediate surroundings, and local neighbourhood; (2) to assess the relation of SSH to two usual markers of socioeconomic position (education and occupation) and a known, socially determined health outcome (hypertension). DESIGN:Population survey measuring SSH, detailed educational and occupational histories, and blood pressure. The SSH is a standardised assessment of the external and internal aspects of someone's building (or house), and of the characteristics of its immediate surroundings and local neighbourhood. SETTING:A sample of participants to the Bus Santé survey between 1993 and 1998, in Geneva, Switzerland. PARTICIPANTS:588 men and women, aged 35 to 74. MAIN RESULTS:The SSH index was highly reproducible (kappa=0.8). Concordance of SSH with education or occupation was good for people of either high or low socioeconomic position, but not for those with medium education and/or occupation. There was a higher prevalence of hypertension in the lowest compared with the highest groups, defined on the basis of education or occupation, but the SSH was the only indicator that showed a higher prevalence of hypertension among people in the middle of the social spectrum. CONCLUSIONS:People of medium education or occupation are heterogeneous with respect to their habitat. Those living in habitats of medium social standing may be most affected by hypertension but this association could not be revealed on the basis of education and occupation alone. The habitat seems to capture different aspects of the socioeconomic position compared with the usual indicators of social class.

Project description:ImportanceEarly-life socioeconomic adversity may be associated with poor cognitive health over the life course.ObjectiveTo examine the association of childhood and midlife neighborhood socioeconomic position (nSEP) with cognitive decline.Design, setting, and participantsThis cohort study included 5711 men and women enrolled in the community-based Atherosclerosis Risk in Communities (ARIC) Study with repeated cognitive data measured over a median 27.0 years (IQR, 26.0-27.9 years) (1990-2019). Statistical analysis was performed from December 2022 through March 2023.ExposureResidence addresses for ARIC Study cohort participants were obtained at midlife (1990-1993) and as recalled addresses at 10 years of age (childhood). A composite nSEP z score was created as a sum of z scores for US Census-based measures of median household income; median value of owner-occupied housing units; percentage of households receiving interest, dividend, or net rental income; percentage of adults with a high school degree; percentage of adults with a college degree; and percentage of adults in professional, managerial, or executive occupations. Childhood nSEP and midlife nSEP were modeled as continuous measures and discretized into tertiles.Main outcomes and measuresA factor score for global cognition was derived from a battery of cognitive tests administered at 5 in-person visits from baseline to 2019. The rate of cognitive decline from 50 to 90 years of age was calculated by fitting mixed-effects linear regression models with age as the time scale and adjusted for race, sex, birth decade, educational level, and presence of the apolipoprotein E ε4 allele.ResultsAmong 5711 ARIC Study participants (mean [SD] baseline age, 55.1 [4.7] years; 3372 women [59.0%]; and 1313 Black participants [23.0%]), the median rate of cognitive decline was -0.33 SDs (IQR, -0.49 to -0.20 SDs) per decade. In adjusted analyses, each 1-SD-higher childhood nSEP score was associated with a slower (β, -9.2%; 95% CI, -12.1% to -6.4%) rate of cognitive decline relative to the sample median. A comparable association was observed when comparing the highest tertile with the lowest tertile of childhood nSEP (β, -17.7%; 95% CI, -24.1% to -11.3%). Midlife nSEP was not associated with the rate of cognitive decline.Conclusions and relevanceIn this cohort study of contextual factors associated with cognitive decline, childhood nSEP was inversely associated with trajectories of cognitive function throughout adulthood.

Project description:Social inequalities in health and disease are well studied. Less information is available on inequalities in biomarker levels indicating subclinical stages of disease such as cystatin C, an early diagnostic marker of renal dysfunction and predictor for cardiovascular disease. We evaluated the relationship between cystatin C, socioeconomic position (SEP) and established cardiovascular risk factors in a population-based study. In 4475 men and women aged 45-75 years participating in the baseline examination of the Heinz Nixdorf Recall Study cystatin C was measured from serum samples with a nephelometric assay. SEP was assessed by education and household income. Linear regression models were used to analyse the association between SEP and cystatin C as well as the impact of cardiovascular risk factors (i.e., body mass index, blood pressure, blood glucose, diabetes mellitus, blood lipids, C-reactive protein, smoking) on this association. After adjustment for age and sex cystatin C decreased by 0.019 mg/l (95% confidence interval (CI) - 0.030 to - 0.008) per five years of education. While using a categorical education variable cystatin C presented 0.039 mg/l (95% CI 0.017-0.061) higher in men and women in the lowest educational category (≤ 10 years of education) compared to the highest category (≥ 18 years). Concerning income, cystatin C decreased by 0.014 mg/l (95% CI - 0.021 to - 0.006) per 1000 € after adjustment for age and sex. For men and women in the lowest income quartile cystatin C was 0.024 mg/l (95% CI 0.009-0.038) higher compared to the highest income quartile. After adjusting for established cardiovascular risk factors the observed associations were substantially diminished. Social inequalities seem to play a role in subclinical stages of renal dysfunction, which are also related to development of cardiovascular disease. Adjustment for traditional cardiovascular risk factors showed that these risk factors largely explain the association between SEP and cystatin C.

Project description:ObjectiveTo examine whether psychosocial factors mediate (explain) the association between socioeconomic position and takeaway food consumption.DesignA cross-sectional postal survey conducted in 2009.SettingParticipants reported their usual consumption of 22 takeaway food items, and these were grouped into a "healthy" and "less healthy" index based on each items' nutritional properties. Principal Components Analysis was used to derive three psychosocial scales that measured beliefs about the relationship between diet and health (α = 0.73), and perceptions about the value (α = 0.79) and pleasure (α = 0.61) of takeaway food. A nutrition knowledge index was also used. Socioeconomic position was measured by highest attained education level.SubjectsRandomly selected adults (n = 1,500) aged between 25-64 years in Brisbane, Australia (response rate = 63.7%, N = 903).ResultsCompared with those with a bachelor degree or higher, participants with a diploma level of education were more likely to consume "healthy" takeaway food (p = 0.023) whereas the least educated (high school only) were more likely to consume "less healthy" choices (p = 0.002). The least educated were less likely to believe in a relationship between diet and health (p<0.001), and more likely to have lower nutritional knowledge compared with their highly educated counterparts (p<0.001). Education differences in beliefs about the relationship between diet and health partly and significantly mediated the association between education and "healthy" takeaway food consumption. Diet- and health-related beliefs and nutritional knowledge partly and significantly mediated the education differences in "less healthy" takeaway food consumption.ConclusionsInterventions that target beliefs about the relationship between diet and health, and nutritional knowledge may reduce socioeconomic differences in takeaway food consumption, particularly for "less healthy" options.
