Today’s Headlines: Calcium Supplements Linked to Heart Disease, Cancer Rates in African Americans Dropping, and More

Calcium Supplements Linked to Increased Risk of Death From Heart Disease in Men:  After reviewing data on over 388,000 participants, they found that men who consumed more than 1,000 milligrams a day of calcium supplements had an increased risk from heart disease compared with non-calcium-users.  The 12-year-long study looked at the correlation between the supplement and levels of death from heart disease and heart attacks. This observation wasn’t seen in women. The lead author of the study notes that, “Our study is based on observation — it is not designed to determine cause and effect.” (USA Today)

Men With Sedentary Lifestyles Have Lower Sperm Count: A study done on 189 men found that those who watched more than 20 hours of television a week had a 44% lower sperm count than men who watched almost no television. In contrast, “Men who engaged in moderate to vigorous exercise for 15 or more hours a week had a 73% higher sperm count than men who exercised less than five hours per week.” However, although a reduced sperm count may indicate lower fertility, a lower number of available sperm “does not absolutely prevent men from fathering a child,” authors said.

Cancer Rates in African Americans Dropping for Some, Growing for Others: The cancer death rate for African Americans declined for some cancers in recent years, narrowing the disparity in cancer death rates compared to whites, according to a new report from the American Cancer Society. Death rates from prostate cancer and smoking-related cancers, like lung cancer, have decreased. However, the racial disparity has widened for colorectal cancer and female breast cancers, “which are most affected by [availability of] screening and treatment.” (EurekAlert)
