The authors of this article analyze data taken from a sample of over 12,000 grandparents in relation to a study on the relationship between grandchild care and grandparent health. Controlling for the covariates of previous health, the results of the study provide no evidence to suggest that grandparents experience negative health changes when taking on the role of care provider for their grandchildren.
