The Health, Aging, and Body Composition Study is a long-term study spanning 10 years that focuses on older adults. The study looked into the relationship between pet ownership status and gender. A sample of 2,434 older adults was selected for the study, and each person was classified based on their pet ownership status and gender. The results of the study were summarized, and it was found that there is a relationship between pet ownership status and gender among older adults. However, without the specifics of the summary of the results, it is difficult to determine the exact nature of this relationship.
