Abstract

Importance: There is a lack of understanding of what is normal in terms of sex steroid levels in older women.

Objective: To determine whether sex steroid levels vary with age in and establish reference ranges for women beyond 70 years.

Design and Setting: Cross-sectional, community based, study.

Participants: 6392 women, aged 70 years and older.

Main Outcome Measures: Sex steroids measured by liquid chromatography-tandem mass spectrometry. A reference group, to establish sex steroid age-specific reference ranges, excluded women using systemic or topical sex steroid, anti-androgen or glucocorticoid therapy or an anti-glycaemic agent.

Results: The reference group of 5326 women had a mean age of 751 ( 42) years, range 70-947 years. Median values (range) were estrone (E1)1812 pmol/L (37-57689), T 038 nmol/L (0035-856), dehydroepiandrosterone (DHEA) 260 nmol/L (007-4685) and SHBG 416 nmol/L (24-1766). Estradiol and dihydrotestosterone were below method sensitivity in 661% and 727% of the samples, respectively. Compared with women aged 70-74 years, women aged 85+ years had higher median levels of E1 (117%, p=001), T (113%, p=002) and SHBG (227%, p<0001) and lower DHEA (30% less, p<0001). Overweight and obese women had higher E1 (p<0001) and T (p<003), and lower SHBG (p<0001) than women with normal body mass index. Smokers had 172% higher median T levels (p=0005).

Conclusion: From the age of 70 years, T and E1 increase with age, despite a steady decline in DHEA. Whether E1 and T are biomarkers for longevity, or contribute to healthy aging merits investigation.
