Figure 2. Cardiovascular Condition Risk vs. Birth Month Results from CUMC and MSH.

(A) shows results from all nine cardiovascular conditions from both MSH (red line) and CUMC (blue line). Seven of nine cardiovascular conditions were correlated at a statistically significant level with MSH data (i.e., the birth month – condition patterns were correlated) using Pearson’s correlation. A significant pattern across the two institutions indicates that the birth month – condition relationship is the same. (B) shows the most correlated result between MSH and CUMC was coronary arteriosclerosis (r = 0.83, p < 0.001). (C) shows the comparison with the peak flu season month using CDC data on flu activity from 1982–83 through 2013–14 (URL: http://www.cdc.gov/flu/about/season/flu-season.htm). We also compared the serum vitamin D levels reported in Meier et al.¹⁸ in (D). We found that birth months that are also months with high serum vitamin D (Jul–Oct.) were ideal for lower coronary arteriosclerosis risk. Additionally, birth months with a high flu burden (Jan–Mar.) were high-risk birth months for coronary arteriosclerosis. This does not indicate that being born in flu season causes coronary arteriosclerosis later in life nor does it indicate that being born in a high vitamin D season lowers risk of coronary arteriosclerosis. These findings merely show support for proposed biological mechanisms, which require further validation from biologists.
