The trends examined by UPenn researches in the paper [0] from my first link span from 1990-2016, vs. that CDC report's 3-year span. From the paper:

"We focus on non‐Hispanic whites because their mortality trends were particularly adverse in the last decade and differ from those of non‐Hispanic Blacks and Hispanics.

In contrast to non‐Hispanic whites, mortality has continued to decline among Hispanics and non‐Hispanic Blacks, although death rates remain substantially higher for Blacks than for whites (Harper, MacLehose, and Kaufman 2014; Murphy et al. 2017; Stein et al. 2017). The underlying mechanisms driving mortality trends for non‐Hispanic whites are fundamentally different from those driving trends for other racial/ethnic groups, as suggested by James and Cossman (2017)."
