The Effect Of Statins On Testosterone In Men And Women, A Systematic Review And Meta-Analysis Of Randomized Controlled Trials, Mary Schooling, Shiu Lun Au Yeung, Guy Freeman, Benjamin J. Cowling

Publications and Research

Background
Statins are extensively used for cardiovascular disease prevention. Statins reduce mortality rates morethan other lipid-modulating drugs, although evidence from randomized controlled trials also suggests that statinsunexpectedly increase the risk of diabetes and improve immune function. Physiologically, statins would beexpected to lower androgens because statins inhibit production of the substrate for the local synthesis of androgens and statins’ pleiotropic effects are somewhat similar to the physiological effects of lowering testosterone, so we hypothesized that statins lower testosterone.

Methods
A meta-analysis of placebo-controlled randomized trials of statins to test the a priori hypothesis that statins lower testosterone. We searched the PubMed, …

Childhood Meat Eating And Inflammatory Markers: The Guangzhou Biobank Cohort Study, Mary Schooling, Chao Q. Jiang, Tai H. Lam, W. S. Zhang, Kar Keung Cheng, Gabriel M. Leung

Publications and Research

Background
We hypothesized that socio-economic development could, via nutritionally driven levels of pubertal sex-steroids, promote a pro-inflammatory state among men but not women in developing countries. We tested this hypothesis, using recalled childhood meat eating as a proxy for childhood nutrition, in southern China.

Methods
We used multivariable linear regression in the Guangzhou Biobank Cohort Study phase 3 (2006-8) to examine the adjusted associations of recalled childhood meat eating, <1/week (n = 5,023), about once per week (n = 3,592) and almost daily (n = 1,252), with white blood cell count and its differentials among older (≥50 years) men (n = 2,498) and women (n = 7,369).

Results
Adjusted for age, childhood socio-economic position, education and smoking, childhood meat eating had sex-specific associations with white blood cell count and lymphocyte count, but not granulocyte count. Men with childhood …
