HDL Update: Age-Related Changes, All-Cause Mortality Risk, And Progress Towards The Optimal Range

2 Replies

In November 2020, I made a HDL video based on a meta-analysis in ~3.4 million subjects that was published in July 2020. In Dec 2020, a larger study (n=15.8 million subjects) was published-those data are presented in the video, and compared against the meta-analysis.

In addition, I’ve tested my HDL 2 more times since November 2020, so how’s my progress for getting it into the optimal range? Also, I attempt to derive clinical significance by identifying correlations for higher HDL with lower Lp(a) and hs-CRP.

Results for my first blood test in 2021 are in-what’s my biological age, and how am I optimizing it?

If you’re interested in calculating your biological age, the spreadsheet is included as an Excel file in this link:
