Abstract
Plasma lipid concentrations and coronary artery atherosclerosis extent were compared
in a retrospective study of female cynomolgus monkeys consuming a moderately atherogenic
diet and housed in single cages or social groups. There was no difference between
single caged and socially housed monkeys in plasma lipid concentrations. However,
females housed in single cages had significantly more coronary artery atherosclerosis
than those housed in social groups. It has been found previously that socially subordinate
females have more extensive coronary artery atherosclerosis than social dominants,
and that subordinates spend more time alone than dominants. Subsequent analyses of
the data presented here revealed that single caged monkeys had significantly more
coronary artery atherosclerosis than socially dominant, but not socially subordinate,
monkeys. Characteristics of single cage housing which could be disease promoting include
restraint and social isolation. These findings should be considered preliminary, and
serve as a basis for further study.
