     Comparative models of hematological risk factors stand to augment our understanding of primate fitness. In humans, cardiovascular and metabolic disorders have rapidly become a worldwide public health issue. With the recent development of factor models of animal personality, we can investigate associations between chimpanzee personality, blood levels of implicated organic macromolecules including triglycerides, cholesterols and white blood cells, and physical measures such as blood pressure, BMI, age, and sex, as informed by research conducted with humans. To this end, personality was assessed in 196 chimpanzees via the 43-item Chimpanzee Personality Questionnaire, in mixed-effect models with hematological data and physical characteristics, gathered during regular check-ups. Controlling for age, sex, & BMI, associations (? = 0.001) were found between blood pressure and the chimpanzee personality domains of extraversion (?=-7.764, S.E=1.907) and openness (?=3.963, S.E.= 1.103), as well as triglyceride levels and agreeableness (?=-24.138877, S.E.= 6.710). Chimpanzee and human metabolic health appear to have much in common. By further developing evolutionary models of cardiovascular and metabolic disorders, we can improve general health for primates. Additionally, health and mortality are linked to personality in humans, and diet has been implicated in the rise of metabolic disorders. Captive primates subsist on industrial diets, as do many wild primates who have come to rely on human food, revealing immediate medical and behavioral targets for improving nonhuman primate health.
