The China Study II: A look at mortality in the 35-69 and 70-79 age ranges

Image
This post is based on an analysis of a subset of the China Study II data, using HealthCorrelator for Excel (HCE) , which is publicly available for download and use on a free trial basis. You can access the original data on the HCE web site, under “Sample datasets”. HCE was designed to be used with small and individual personal datasets, but it can also be used with larger datasets for multiple individuals. This analysis focuses on two main variables from the China Study II data: mortality in the 35-69 age range, and mortality in the 70-79 range. The table below shows the coefficients of association calculated by HCE for those two variables. The original variable labels are shown. One advantage of looking at mortality in these ranges is that they are more likely to reflect the impact of degenerative diseases. Infectious diseases likely killed a lot of children in China at the time the data was being collected. Heart disease, on the other hand, is likely to have killed more people in the...

Losing weight without developing gallstones

Gallstones are estimated to affect 1 in 10 people in North America. Those who are obese have a higher likelihood of developing gallstones. Most at risk of gallstones as a result of obesity are Native Americans, the elderly, and Caucasian women in their forties who haven’t yet reached menopause. Gallstones are so named because they develop in the gallbladder, a small organ that stores and releases the bile made by the liver. Bile is a dark green fluid containing bile salts and cholesterol. The gallbladder releases bile into the small intestine to assist in digesting fats more efficiently. However, if the bile contains high concentrations of cholesterol, then stones too difficult for the bile salts to dissolve may develop. Because gallstones usually form without any symptoms, most people don’t know they have them or may feel only minor symptoms such as abdominal pain after eating a fatty meal. However, if a stone becomes lodged in a bile duct causing blockage, it can result in sudden pai...
