Relative to normal weight, both obesity (all grades) and grades 2 and 3 obesity were associated with significantly higher all-cause mortality. Grade 1 obesity overall was not associated with higher mortality, and overweight was associated with significantly lower all-cause mortality.
Thanks!
Both look like very decent studies so I am not certain where the difference comes from. I suspect that the division into age brackets, or averaging across all of the them may be the cause. Either way, it seems that the effects of being slightly overweight are barely statistically significant. The more you know
Sure!
