Concurrent and enduring associations between married partners' shared beliefs and markers of aging.

ABSTRACT: Beliefs about aging are grounded in social experience. This study considered the extent to which married older adults' shared beliefs about aging and markers of aging maintain a concurrent and enduring association with their partners' beliefs about and markers of aging. Data from the 2010/2012 and 2014/2016 waves of the Health and Retirement Study provided measures of husbands' and wives' (3,779 couples) positive and negative beliefs about aging and internal (Cystatin C) and external (grip strength) markers of aging at 2 time points. Latent dyadic models parsed beliefs and markers into partners' individual and shared variances, which were connected both cross-sectionally and longitudinally. Longitudinal analysis showed that the cross-sectional associations between shared beliefs and markers of aging were stable over 4 years. Partners' shared beliefs and markers of aging were found to have enduring associations with each other over time. The enduring association between grip strength and future negative beliefs remained significant after accounting for partner selection and similarity in health. Model comparisons across marriage duration and emotional closeness showed partners' beliefs to be more similar in marriages that were either long established or emotionally close. In all groups, shared beliefs and markers of aging were associated with each other over time. The association between positive beliefs and future grip strength was stronger in long-established than in recent marriages. In summary, this study provides evidence that, within older couples, beliefs about aging are shaped in part through experiences of aging together.

Project description:BackgroundChildhood maltreatment is one of the strongest predictors of adulthood depression and alterations to circulating levels of inflammatory markers is one putative mechanism mediating risk or resilience.AimsTo determine the effects of childhood maltreatment on circulating levels of 41 inflammatory markers in healthy individuals and those with a major depressive disorder (MDD) diagnosis.MethodWe investigated the association of childhood maltreatment with levels of 41 inflammatory markers in two groups, 164 patients with MDD and 301 controls, using multiplex electrochemiluminescence methods applied to blood serum.ResultsChildhood maltreatment was not associated with altered inflammatory markers in either group after multiple testing correction. Body mass index (BMI) exerted strong effects on interleukin-6 and C-reactive protein levels in those with MDD.ConclusionsChildhood maltreatment did not exert effects on inflammatory marker levels in either the participants with MDD or the control group in our study. Our results instead highlight the more pertinent influence of BMI.Declaration of interestD.A.C. and H.W. work for Eli Lilly Inc. R.N. has received speaker fees from Sunovion, Jansen and Lundbeck.

Project description:Background: Lung cancer and oesophageal cancer are prevalent malignancies with rising incidence and mortality worldwide. While some environmental and behavioural risk factors for these cancers are established, the contribution of genetic factors to their pathogenesis remains incompletely defined. This study aimed to interrogate the intricate genetic relationship between lung cancer and oesophageal cancer and their potential comorbidity. Methods: We utilised linkage disequilibrium score regression (LDSC) to analyse the genetic correlation between oesophageal carcinoma and lung carcinoma. We then employed several approaches, including pleiotropic analysis under the composite null hypothesis (PLACO), multi-marker analysis of genomic annotation (MAGMA), cis-expression quantitative trait loci (eQTL) analysis, and a pan-cancer assessment to identify pleiotropic loci and genes. Finally, we performed bidirectional Mendelian randomisation (MR) to evaluate the causal relationship between these malignancies. Results: LDSC revealed a significant genetic correlation between oesophageal carcinoma and lung carcinoma. Further analysis identified shared gene loci including PGBD1, ZNF323, and WNK1 using PLACO. MAGMA identified enriched pathways and 9 pleiotropic genes including HIST1H1B, HIST1H4L, and HIST1H2BL. eQTL analysis integrating oesophageal, lung, and blood tissues revealed 26 shared genes including TERT, NKAPL, RAD52, BTN3A2, GABBR1, CLPTM1L, and TRIM27. A pan-cancer exploration of the identified genes was undertaken. MR analysis showed no evidence for a bidirectional causal relationship between oesophageal carcinoma and lung carcinoma. Conclusions: This study provides salient insights into the intricate genetic links between lung carcinoma and oesophageal carcinoma. Utilising multiple approaches for genetic correlation, locus and gene analysis, and causal assessment, we identify shared genetic susceptibilities and regulatory mechanisms. These findings reveal new leads and targets to further elucidate the genetic basis of lung and oesophageal carcinoma, aiding development of preventive and therapeutic strategies.
