Abstract

OBJECTIVES:

The rs12611091 variant in the BR serine/threonine kinase 1 gene is one of the variants previously associated with age at natural menopause. So far, this variant has not been replicated in Taiwanese women. The purpose of this study was to determine the association between rs12611091 and age at natural menopause based on physical activity.

METHODS:

A total of 1,758 women were eligible for analysis whose information about menopause was collected from the Taiwan Biobank. Multiple linear regression analysis was used for analysis.

RESULTS:

The mean age (standard deviation) at natural menopause was 50.82 (3.59) years. Of the eligible participants, 56.94% were rs12611091 CC carriers, 36.69% were TC carriers, and 6.37% were TT carriers. Compared to CC carriers, TC and TT carriers were associated with early menopause (β = -0.42, P = 0.02 and -0.87, P = 0.01, respectively). There was a significant interaction between rs12611091 and physical activity (P for interaction = 0.02). Compared to rs12611091 CC carriers, TC and TT carriers who were physically inactive were significantly associated with earlier menopause (β = -0.88, P < 0.01 and -1.25, P = 0.02, respectively).

CONCLUSION:

We demonstrated that rs12611091 variant was associated with age at natural menopause especially among inactive women in Taiwan. That is, women with TC and TT genotypes who were physically inactive were significantly associated with earlier natural menopause compared to those with CC genotype.
