Hormone Therapy Cuts Diabetes Risk in Women

Article excerpt

Women considering the risks and benefits of hormone therapy should be informed of the link between hormones and a decreased risk of diabetes, especially if they are at risk for the disorder, according to Dr. Wulf Utian, executive director of the North American Menopause Society, in Cleveland.

"While hormone therapy [HT] is not indicated for the prevention of diabetes, women with diabetes risk factors who are considering it for a valid indication should understand the evidence in this area," Dr. Utian said in an interview.

"For these women, the link between HT and diabetes might fall on the benefit side of the equation."

NAMS' newly revised position statement on HT is the group's first to review this evidence, Dr. Utian said. "In 2004 [when NAMS issued its last position paper], there were not enough data to address this issue. Since then, a number of published studies have shown the same link between HT and a decreased incidence of diabetes."

The paper reviewed three studies on the subject, granting Class I status to the evidence presented in each one: two subanalyses of the Women's Health Initiative (WHI) and one subanalysis of the Heart and Estrogen/Progestin Replacement Study (HERS).

The first of the WHI studies, published in 2004, examined the effect of HT on diabetes development in the 16,600 women included in the estrogen/progestin arm (Diabetologia 2004;47:1175-87). After 5 years of follow-up, women in the active group were 21% less likely to develop diabetes than those in the placebo group (277 cases vs. 324 cases--a significant difference).

The numbers achieved greater significance when the analysis was restricted to the small subgroup of women who remained compliant with therapy throughout the follow-up period. In this group, the decreased risk was 33%.

The difference seemed to be driven by steady improvements in fasting glucose and insulin resistance in the active group, the authors wrote. The risk ratios remained unchanged after adjusting for body mass index (BMI) and waist circumference.

Insulin resistance and glucose level were also the driving forces behind the smaller risk reductions seen among women in WHI's estrogen-only arm (Diabetologia 2006;49:459-68). …
