This whole study strikes me as rather weak, I wouldn't give assign too much importance to the results. As mentioned below, the number of participants was rather low (though that is not uncommon in the life sciences and medicine). Also, the statistics appear to be sloppy, or at any rate not sufficiently documented to be verifiable. Thirdly, they tried to investigate too many things at once ("diet, smoking habit, physical activity and education"). And lastly, they base their whole study on the supposed link between telomere length and human longevity - a somewhat obsolete hypothesis.
