ETA: In research published after the twentieth century, Elizabeth Brainerd used archival and anthropometric data to provide a detailed analysis of living standards in the U.S.S.R., admitting that for all their faults, the Soviets still achieved

Remarkably large and rapid improvements in child height, adult stature and infant mortality [and] significant improvements likely occurred in the nutrition, sanitary practices, and public health infrastructure.

They weren't, but it's still a pretty big contrast between the 60s (which started of course in 1953) and even the mid-late 70s. The problems didn't start with Gorbachev
