Factors associated with healthy aging in septuagenarian and nonagenarian Mexican adults

Abstract

To examine the factors associated with healthy aging in a cohort of Mexican adults after a follow-up of 14 years. Study design: Participants were part of a prospective cohort of the Mexican Healthy Aging Study (MHAS), from which we included 5142 individuals aged 63 years or more. Main outcome: Healthy aging, defined as reaching age 77 or 90 without major chronic conditions or physical limitations. Measures: Information on age, education, marital status, smoking, alcohol consumption, physical activity, selfperceived depression, health conditions and history of age-related diseases was collected at baseline and followup. Results: Among the overall cohort, 57.8% experienced healthy survival to age 77 and 42.2% had died before age 77 or were undergoing normal aging. Participants with long-lived parents and who exercised had a lower risk of being non-healthy agers. Being overweight, obese or a smoker increased the risk of being a non-healthy ager. Physically active participants had increased odds of healthy aging at age 77 (OR: 1.17; 95% CI: 1.01-1.46) and at age 90 (OR: 1.5; 95% CI: 1.01-2.24). Depression had a negative relationship with healthy aging at age 90 (OR: 0.66; 95% CI: 0.45-0.97). Maternal longevity was associated with healthy aging only at age 77 (OR = 1.34; 95% CI: 1.04-1.72). Conclusions: Our findings support the view that a combination of genetic and behavioral factors is associated with healthy aging. In accordance with findings in Caucasian populations, our data suggest for the first time that there might also be a genetic determinant for healthy ageing in Latin Americans.

Oxidative Stress Risk Is Increased with a Sedentary Lifestyle during Aging in Mexican Women

“…In the risk analysis, only sedentary lifestyle and the age were risk factors for OS, and the other lifestyle prooxidant behaviors were not related. These results are consistent with the report of a study of factors associated with healthy aging of the Mexican population; the authors point out that smoking, alcohol intake, depression, and overweight/obesity are not related to the dependent variable [ 48 ]. Although a different association was sought, it seems that these variables are not related to events in which the age is included in the models.…”

The Role of Psychological Time in Late Socialization. A SEM Analysis

“…e socialization of older persons (late socialization) refers to the development of knowledge and skills, the adoption of new behaviors, and changes in values, all of which should ensure adequate adaptation to one's age and appropriate participation in interaction with society (Dubynina, 2019). Related concepts include active aging (Cao, 2022;Zheng et al, 2023); successful aging (Martinson, & Berridge, 2015;Zhang et al, 2018); healthy aging (Scult et al, 2015;Arroyo-Quiroz et al, 2020); e ective aging (Strizhitskaya, 2017); favorable aging (Sergienko, & Kharlamenkova, 2018); social adaptation/disadaptation (Prokhorova, 2022); desocialization (Belikov, 2019); and resocialization (Perinskaya, 2005;Serdakova et al, 2020). ese concepts try to describe the e ectiveness of socialization at a late age: how successfully a person can adapt in society when changing his or her lifestyle (retirement).…”

How Healthy Aging and Contact With Children Are Associated With Satisfaction in Middle-Aged and Older Parents in China: A Mediation Analysis

“…Healthy aging is a holistic view that encompasses both biological and medical aspects of aging, as well as subjective experiences and meanings, and emphasizes functional definitions of autonomy, participation, and wellbeing ( 13 ). As healthy aging is a comprehensive concept it is affected by many factors, such as demographic background, socio-economic status, health behaviors, and social interaction ( 14 – 16 ), all of which must be measured.…”
