In Table 4 on page 562 of the original version of this article, the results for ‘Single or divorced’ and ‘Married or remarried’ categories under Hobby*marital status (p = 0.044) in the first column are mistakenly swapped. Therefore the fields ‘Single or divorced’ and ‘Married or remarried’ should be reversed. This issue is only related to Table 4, and the in-text results are correct.
