Who Has Active Lifestyles? Sociodemographic and Personality Correlates of Activity Diversity in Two Samples of Adults

ObjectivesActivity diversity—an index of active lifestyles that captures variety (number) and evenness (consistency) in activity engagement—is known to support health in adulthood. However, less is known who has higher or lower activity diversity, information that helps identify individuals who may be at greater risk for poor health. This article examined sociodemographic characteristics and Big Five personality traits that may be associated with activity diversity.MethodsWe used 2 independent project samples (nsample1 = 2,699; nsample2 = 301). Sample 1 included U.S. national adults in a wide age range (25–84). Sample 2 included U.S. community-dwelling older adults (age = 65–89). Each study asked about different types of activity engagement using surveys. The activity diversity index was calculated in each sample, using Shannon’s entropy method.ResultsIn Sample 1, older adults, women, non-Hispanic White individuals, married/partnered individuals, and those with higher education and fewer functional limitations had higher activity diversity. Additionally, higher conscientiousness, higher extraversion, and lower neuroticism were each associated with higher activity diversity after controlling for sociodemographic factors. Extraversion and neuroticism remained significant in the younger group (age
