Doctoral student Lily Nosraty investigated the prevalence of successful aging and its association with sociodemographic factors in a representative population sample in the Vitality 90+ study. Her models included both physical, psychological and social components in different combinations, and the prevalence varied between 1.6% and 18.3 % depending on the model. Successful aging was more common in men and in community-dwelling people, and in most models is was also associated with younger age, being married and having a higher education. In very old age, successful aging may be better approached by models that focus more on autonomy, adaptation and sense of purpose, says Ms. Nosraty.
