a

Age group treated as categorical (4 dummy variables) in all models

b

Sociodemographic/patient characteristics include race, marital/partnered status, children under 18 in home, household income, employment, and education, number of comorbidities

c

Cancer-related variables include time since diagnosis, stage, type of surgery, radiation, chemotherapy

d

Symptoms include vasomotor symptoms and bodily pain

e

Psychosocial variables include role of faith, meaning, peace, illness intrusiveness, active coping, passive coping, perceived attractiveness, social support, pessimism, optimism

f

Null hypothesis being tested is that ORs for all age groups, relative to age group 25–44, are the same and are 1.0
