I can’t find any evidence of whether they controlled for obesity (which is certainly believed to be a factor is several of the diseases that a correlation was found for). But other than that, I’d say that it is a very interesting study.

Low adolescent IQ is a strong predictor for obesity later in life. [1] So I'm not sure how or why you'd want to control for obesity. You could be looking at a comorbid effect. Low IQ -> obesity -> early death. [1] - http://circ.ahajournals.org/content/124/Suppl_21/A12601.short http://circ.ahajournals.org/content/124/Suppl_21/A12601.shor...
