Criteria for successful aging: free of disease and disability; high levels of physical and cognitive functioning; and social engagement. The aim of this study was to describe factors associated with successful aging among older peopleMethods: The literature search strategy identified 1.914 articles. The PRISMA strategy was used to identify articles that met inclusion criteria. Initially 255 duplicated studies were excluded; resulting in 1659 articles screened for inclusion in this review. A further 1567 articles were removed based on the title and abstract. The remaining 32 articles were assessed for inclusion this review. Nineteen articles were excluded. In total 13 studies met inclusion criteria for this review. These 13 studies were assessed for quality, data extraction and synthesis.Results: The factors associated with successful aging are age, gender, few physical morbidities, absence of depression, body weight or BMI in the overweight range, carrying out more than six AADL and high levels of physical activity, education, smoking, alcohol consumption, marital status, proactive engagement, wellness resources, positive spirit, and valued relationships, sleep quality, leisure activity, economic status, religious activity, and high perceived meaningfulness.Conclusion: The factors that influence successful aging are socio-demographic factor, physiological, psychological, and lifestyle behavioral factors.

Introduction: Earthquakes can cause mental health disorders in adolescents, one of which is post-traumatic stress disorder (PTSD). The present study aimed to assess the effect of social support on post-traumatic stress disorder in adolescents after an earthquake.Methods: The study was a systematic review with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach. Articles were searched for using the Scopus, ScienceDirect, ProQuest, EBSCO and SAGE databases before classifying them into 3 categories: prevalence, risk factors, social support, and post-traumatic stress disorder. The inclusion criteria regarding the literature were documents that were original; where the source was from a journal; where the article was written in English and where the full text was available.  The age of the subjects in the articles was determined to be in the range of 10-20 years old. The publication time limit was 2015 to 2020.Results: Adolescents who experienced an earthquake were found to demonstrate a high prevalence of post-traumatic stress disorder with the proportion in girls being higher than boys. Showing social support has a significant effect on PTSD after an earthquake. The earthquake-related factors that were the most strongly associated with probable PTSD were feeling scared of dying and exposure to an earthquake.Conclusion: Social support and the prevalence rates of PTSD should be observed in more detail. These results indicate that it is important to provide and strengthen the social support available to reduce the risk and severity of post-traumatic stress disorder after an earthquake among adolescents.
