“…Finally, while higher AL risk was strongly predicted by lower levels of education, no associations were found with sex, household income, APOEe4 genotype status, or engagement in stimulating activities. The lack of association to household income somehow disagree with previous studies performed in Latin-American cohorts, where AL was highly related to a range of socio-economic disadvantages, such as housing conditions, social or religious support and neighbourhood characteristics [5,42]. Nonetheless, it should be noted that according to recent demographic analyses, educational level is not correlated with per-capita income in the Chilean population [43], thus it could be expected a signi cant relation to education in the absence of association to household income in the present cohort.…”

“…To date, evidence shows positive relationship between AL and risk of developing several pathological conditions, such as major depression, brain structure deterioration, cardiovascular disease, diabetes type 2, cancer, functional decline, and dementia [3]. Although evidence reports important ethnic modulatory effect on AL [4], most studies have been performed in whitecaucasian cohorts from high-income countries, and only few reports can be found in Latin/Hispanic populations, usually among Mexican or Central-American immigrants within the US [5][6][7][8], with very little evidence from South American cohorts [9][10][11].…”

Background Only few studies of Allostatic Load (AL) have been conducted in Latin/Hispanic populations, and even fewer performed in South American cohorts. Here, we replicated a recently proposed algorithm to derive an AL index in a Chilean cohort of cognitive healthy adults.Methods Using data from the GERO cohort (n = 166, age 76.92 ± 5.07 years, 80.12% females) we generated an AL risk index through a comprehensive algorithm (ALCS). Due to the age and the large disparity between males and females of the sample, modifications to the original algorithm were introduced. An empirical algorithm (ALES), without including clinical thresholds was also derived for model comparison.Results Neither ALCS nor ALES achieved adequate goodness of fit. After age and sex corrections, both algorithms largely improved, but only ALES showed satisfactory model fit. ALCS largely improved when correcting for available age-specific clinical thresholds, although failed to achieve sufficient goodness of fit. A final inclusion of an additional inflammatory biomarker resulted in further improvement of ALES, but not on ALCS.Conclusions Even when satisfactory model fit was not achieved by the comprehensive scoring, it was largely improved when some clinical values were corrected for ages ≥65. The ALES algorithm, which do not include clinical thresholds, achieved satisfactory fit after correcting for sample disparities between sexes. This suggests the need to consider the suitability of clinical thresholds developed in younger populations and the need to develop specific thresholds for assessing older adults.Trial registration Geroscience Center for Brain Health and Metabolism Research Project Nº 1140423, approved in May 2015 by the Scientific Ethics Committee (SEC) of the Western Metropolitan Health Service (WMHS), Santiago (Chile).

“…Findings from our study should be considered in the context of 5 limitations. First, in this secondary analysis, we were unable to account for unmeasured confounders that may also influence unmet social needs and physiologic stress, either independently or in relation to each other (eg, body mass index, 69 experiences of racism, 3 , 70 immigration status 71 ). Second, while LPA is a promising approach for determining subgroups according to data patterns, class assignment is based on probabilities and therefore may lead to misclassification.…”

Unmet Social Needs and Patterns of Hair Cortisol Concentration in Mother–Child Dyads

et al. 2023

Background Mothers and their children demonstrate dyadic synchrony of hypothalamic–pituitary–adrenal (HPA) axis function, likely influenced by shared genetic or environmental factors. Although evidence has shown that chronic stress exposure has physiologic consequences for individuals—including on the HPA axis—minimal research has explored how unmet social needs such as food and housing instability may be associated with chronic stress and HPA axis synchrony in mother–child dyads. Methods We conducted a secondary analysis of data from 364 mother–child dyads with low-income recruited during a randomized trial conducted in an urban pediatric clinic. We used latent profile analysis (LPA) to identify subgroups based on naturally occurring patterns of within-dyad hair cortisol concentration (HCC). A logistic regression model predicted dyadic HCC profile membership as a function of summative count of survey-reported unmet social needs, controlling for demographic and health covariates. Results LPA of HCC data from dyads revealed a 2-profile model as the best fit. Comparisons of log HCC for mothers and children in each profile group resulted in significantly “higher dyadic HCC” versus “lower dyadic HCC” profiles (median log HCC for mothers: 4.64 vs 1.58; children: 5.92 vs 2.79, respectively; P < .001). In the fully adjusted model, each one-unit increase in number of unmet social needs predicted significantly higher odds of membership in the higher dyadic HCC profile when compared to the lower dyadic HCC profile (odds ratio = 1.13; 95% confidence interval [1.04-1.23]; P = .01). Conclusion Mother–child dyads experience synchronous patterns of physiologic stress, and an increasing number of unmet social needs is associated with a profile of higher dyadic HCC. Interventions aimed at decreasing family-level unmet social needs or maternal stress are, therefore, likely to affect pediatric stress and related health inequities; efforts to address pediatric stress similarly may affect maternal stress and related health inequities. Future research should explore the measures and methods needed to understand the impact of unmet social needs and stress on family dyads.

How Do We Measure Stress in Latinos in the United States? A Systematic Review

et al. 2021

View full text Add to dashboard Cite

Background: Previous research has documented that Latinos report higher levels of stress than other ethnicities and are an increasing portion of the demographics of the United States. While there are many measures to assess stress and other stress-related conditions, there are no systematic reviews to date to assess whether the current measures of generalized stress are valid or reliable in Latinos in the United States. The purpose of this systematic review was to examine the current state of the literature assessing the psychometric properties in stress measures in this population. Methods: We used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to review the literature from January 1990 to May 2020 for studies, which measured the psychometric properties of scales measuring generalized stress in Latinos in the United States. Results: Twelve studies measured the psychometric properties of eight scales of generalized stress. The 10-item Perceived Stress Scale, the Hispanic Stress Inventory, the Hispanic Women's Social Stressor Scale, and the Family Obligation Stress Scale show the strongest reliability and validity for measuring stress in Latinos in the United States. Most studies were done in traditional immigration destinations in the United States. Conclusion: While four scales which show acceptable reliability and validity for measuring stress in Latinos in the United States, continuing to develop and further validate these scales within Latino communities will be critical to understand and address Latino stress more comprehensively. Our findings can inform health research and clinical interventions for this at-risk community.
