a
Results not shown here indicated other significant differences across union categories (p < .05): those who entered a union gained significantly more BMI than those who dissolved a union, were married stable, or were widowed stable.
b
Results not shown here indicated Normal BMI × Entered a union was significantly different than the normal BMI interaction effects for all other union categories.
