“…For instance, the impact of SEP on cognition has been linked to its influence on attaining peak performance in midlife, which may affect the timing and trajectory of subsequent declines in later life (10). Further complicating the picture, some have found that slower cognitive decline in later life has been associated with upward mobility in SEP (9), although such an association with diet has been shown to require consistently high diet quality starting at least from midlife (44).…”

“…Because the 3MS provides a single measure of global cognition, we could not examine whether the observed associations were restricted to specific cognitive domains. Although we used multiple indicators reflecting both psychosocial and material dimensions of SEP, it could be useful to study additional indicators across the life course (i.e., wealth, household conditions, parental SEP) because upward mobility in SEP has been shown to impact cognition (9). Differences between the analyzed and unanalyzed participants in income and education may have resulted in overestimated and underestimated associations of the prudent and Western patterns, respectively.…”

“…Socioeconomic position (SEP)-represented by indicators such as income, education and occupation-is an established determinant of dietary intake such that higher SEP is generally related to better diet quality (8). Interestingly, SEP is also associated with differences in cognitive function across the life course (9)(10)(11)(12). Accumulated animal evidence suggests that both diet (13,14) and conditions simulating SEP (15,16) modulate neurobiological mechanisms that mediate changes in brain structure and function as a response to these life experiences-a capacity broadly referred to as ''brain plasticity.''…”

Both diet quality and socioeconomic position (SEP) have been linked to age-related cognitive changes, but there is little understanding of how the socioeconomic context of dietary intake may shape its cognitive impact. We examined whether equal adherence to "prudent" and "Western" dietary patterns, identified by principal components analysis, was associated with global cognitive function [Modified Mini-Mental State Examination (3MS)] in independently living older adults with different SEPs (aged 68-84 y; n = 1099). The interaction of dietary pattern adherence with household income, educational attainment, occupational prestige, and a composite indicator of SEP combining all 3 was examined in multiple-adjusted mixed models over 3 y of follow-up in participants of the NuAge study (Quebec Longitudinal Study on Nutrition and Successful Aging). Adherence to the prudent pattern (vegetables, fruits, fish, poultry, and lower-fat dairy products) was related to higher 3MS scores at recruitment only in the upper categories of income [parameter estimate (B): 0.56; 95% CI: 0.11, 1.01], education (B: 0.44; 95% CI: 0.080, 0.80), or composite SEP (B: 0.37; 95% CI: 0.045, 0.70). High prudent pattern adherence was associated with less cognitive decline only in those with low composite SEP (B: 0.25; 95% CI: 0.0094, 0.50). Conversely, adherence to the Western pattern (meats, potatoes, processed foods, and higher-fat dairy products) was associated with more cognitive decline (B: -0.23; 95% CI: -0.43, -0.032) only in those with low educational attainment. In summary, among individuals with equivalent diet quality, the magnitude and characteristics of the diet-cognition relationship depended on their socioeconomic circumstances. These results suggest that interventions promoting retention of cognitive function through improved diet quality would provide maximum benefit to those with relatively low SEP.

“…Despite the large number of studies on psychosocial factors and their impacts on the performance of children of different ages in cognitive tasks, most of them use IQ or academic achievement measures (Forns et al 2012;Haan et al 2011). In the present study, neuropsychological variables were added to traditional IQ evaluation, following recent studies that assess neuropsychological functions separately (Noble and Farah 2013;Raizada and Kishiyama 2010).…”

The aim of this study was to assess the effect of family socioeconomic status (SES) and parental education on non-verbal IQ and on the processing of oral and written language, working memory, verbal memory and executive functions in children from different age ranges. A total of 419 Brazilian children aged 6-12 years old, attending public and private schools from Porto Alegre, RS participated in the study. Structural equation analyzes revealed that in the general model (for all ages), the SES contributed to cognitive performance -IQ, verbal memory, working memory, oral and written language and executive functions (28, 19, 36, 28 and 25 %, respectively). SES had stronger effects on younger children (up to nine years old), in most cognitive tasks examined. Probably, after this age, a combination of factors such as schooling, living in other social environments, among others, may mitigate the effects of family socioeconomic status.

“…For instance, Sattler et al [12] have shown, in 321 elderly participants from the Interdisciplinary Longitudinal Study on Adult Development and Aging followed up for 12 years, that high socioeconomic status measured by monthly household income reduced the risk of developing cognitive impairment by 69% in comparison to subjects with low socioeconomic status. Other studies have used occupation [13], both occupation and education [14], or occupation, education and income [15,16] to assess socioeconomic status. All showed a significant association with dementia or cognitive decline.…”

Background: This study investigates the relationship between psychosocioeconomic precariousness, cognitive decline and risk of developing dementia. Methods: The sample consisted of 3,710 subjects aged ≥65 years. Psychosocioeconomic precariousness was assessed with a ratio consisting of 8 self-reported items of poor socioeconomic status and psychosocial vulnerability. Results: Participants who were considered as precarious (n = 1,444) presented greater cognitive decline (β = -0.07; p = 0.0067) after adjusting for various confounders. They also had a 36% increased risk of developing dementia (hazard ratio 1.36, 95% confidence interval 1.17-1.57; p < 0.0001) over the 25-year follow-up period. Conclusion: Psychosocioeconomic precariousness is associated with greater cognitive decline and increased risk of developing dementia. This relationship can be explained in light of the concept of cognitive reserve and strengthens the need to consider psychosocioeconomic precariousness of elderly individuals in the definition of successful ageing policies.

Life-span Socioeconomic Trajectory, Nativity, and Cognitive Aging in Mexican Americans: The Sacramento Area Latino Study on Aging

Abstract: Heterogeneity of cognitive aging among diverse race/ethnic groups may be influenced by intergenerational changes in SES, cultural norms, and behaviors and changes in health related to changes in the social and physical environment.
