Young age at onset was associated with a longer duration of the menopausal transition (MT), a recent study found. Data for 1,145 women from 4 sites of the Study of Women’s Health Across the Nation were analyzed. Participants from 4 racial/ethnic groups were included: African American, white, Chinese, and Japanese. Women completed daily menstrual calendars from 1996 to 2006 and questions on hormone therapy use monthly. Researchers found:
- Adjusted median duration of the MT ranged from 4.37 years among the oldest age at onset quartile to 8.57 years among the youngest age on onset quartile.
- Cigarette smoking was associated with an earlier onset and a shorter duration.
- African American women had a longer duration that white women.
- Body mass index (BMI) was associated with a later onset of the MT, but not its duration.
