Lactation lowers risk of T2DM after gestational diabetes

Lactation lowers risk of T2DM after gestational diabetes
(HealthDay)—For women with previous gestational diabetes mellitus (GDM), lactation is associated with reduced risk of type 2 diabetes mellitus (T2DM), although there is no benefit for long-term lactation, according to a review and meta-analysis published online March 25 in the Journal of Diabetes Investigation.

Lijun Feng, from Zhejiang University in Hangzhou, China, and colleagues conducted a systematic review to examine the effect of on the development of T2DM in with prior GDM. The meta-analysis included 13 cohort studies.

The researchers found that lactation was significantly associated with a lower risk of T2DM compared with no lactation (relative risk, 0.66; 95 percent interval, 0.48 to 0.90; P < 0.001). This correlation was prominent in studies conducted in the United States (relative risk, 0.66; 95 percent confidence interval, 0.43 to 0.99), regardless of study design, smaller sample size, follow-up duration greater than one year, and use of adjusted data. By pooling data from three studies, long-term lactation (more than one to three months postpartum) was not associated with T2DM risk compared with no lactation (relative risk, 0.69; 95 percent confidence interval, 0.41 to 1.17).

"This meta-analysis demonstrated that lactation was associated with a lower risk of T2DM in women with prior GDM," the authors write. "Further, no significant relationship between long-term lactation and T2DM risk was detected."
