Life course effects on age at menopause among Bangladeshi sedentees and migrants to the UK.

Objectives: To assess how different variables experienced across the life course, but particularly during early life, might affect age at menopause among 174 Bangladeshi migrants to London by comparing them to 157 nonmigrant sedentees and 154 women of European descent in London.

Methods: Participants were aged 35-59 years, with no exogenous hormone use in the past three months, not pregnant or lactating, with no history of hysterectomy or oophorectomy. Face-to-face interviews and anthropometric measures were carried out.
