“…A study by Tolppanen et al [ 20 ] found that older individuals with higher BMI were less likely to develop dementia than those with lower BMI. Based on previous studies, this difference could be due to the effect of BMI on cognitive performance according to underlying health conditions and non-modifiable factors (such as age and sex) [ 37 , 38 ].…”

Background Previous studies have examined relationship between cognitive function and lifestyle; however, the nature of this relationship is expected to vary in diverse cultural and low-income setting where lifestyle practices differ from those in high-income countries. Aim This study aims to investigate the correlation between lifestyle factors and cognitive function among individuals aged 60 years and older in 2021. Methods This cross-sectional, Community-based study involved 300 older adults from comprehensive urban health centers in Khorramabad, Iran, selected through stratified cluster sampling. Data were collected using the demographic information questionnaire, Mini-Mental State Examination, and Lifestyle Questionnaire. Data management and analysis were performed using SPSS (version 22) and independent t-tests, Pearson's correlation coefficient, ANOVA, and multiple linear regression analysis were used. A p value < 0.05 was considered significant. Results The study included 156 males (52%) and 144 females (48%). Findings revealed a significant correlation between cognitive function and lifestyle (P < 0.001). Multiple linear regression analysis indicated that physical health, environmental health, exercise, accident prevention, and avoidance of medication exerted the most significant positive effect on cognitive function. Conversely, social health exhibited a notable negative influence on cognitive function. (P < 0.001). Conclusion The results suggest that specific aspects of lifestyle, such as physical health, accident prevention, and avoidance of medication are associated with cognitive function in older adults. Consequently, lifestyle promotion programs may enhance cognitive function and improve the quality of life among older adults.

Background Early life adversity has been shown to have long-lasting detrimental effects on a variety of biopsychosocial outcomes. Early adversity and its consequences may directly or indirectly affect cognitive aging and increase the risk of developing dementia in older age. Investigating the biopsychosocial outcomes associated with early adverse experiences is essential to inform health policies and promote healthy cognitive development across the life course. Methods The aim of this study is to investigate the effect of early adversity (i.e., abuse and deprivation) on selected outcomes (i.e., physical and mental health, lifestyle, and cognition) in two UK cohorts (the English Longitudinal Study of Ageing (ELSA), N = 12,653, Mdnage = 66, SDage = 9.58; UK Biobank, N = 502,360, Mdnage = 58, SDage = 8.09). In both cohorts, adversities were self-reported retrospectively, and only those adversity types assessed in both cohorts were utilized. A post-hoc analysis was performed to examine the role of education as a mediator of the association between early adversity and the selected outcomes. Results Most of the results show that early adversity is negatively associated with health (both physical and mental), lifestyle, and cognition while also highlighting the important mediating role of education. However, differences exist according to the specific adversity experienced and the cohort studied. Conclusions The results found bring into attention the complex associations between early adversity and multiple later life outcomes, and suggest that various mechanisms might be at play. Furthermore, the findings highlight the importance of multi-cohort comparisons for the generalization of the results.
