The relationship between the number of children and the risk of heart disease in both mothers and fathers forms a curve: the chances of heart disease appear lowest in parents of two children, then rise as the number of children increases. In families with two children, the addition of every new child increases the risk of heart disease among mothers by 30%, and among fathers by 12%.
