After publication, it came to the authors’ attention that after revision and update of the literature search, some numbers were inconsistently implemented (differences between tables and text) and some reference categories were incorrectly transformed in the original article [1]. This Correction displays the corrected information ahead. These adjustments did not change the results.

  • The third sentence of the Findings sub-section of the Abstract should instead state the following:

Higher neighbourhood walkability was associated with lower T2DM risk/prevalence (n=6, OR=0.79 (95%-CI=0.7-0.9; I2=92%)) and more green space was associated with lower T2DM risk/prevalence (n=4, OR=0.91 (95%-CI=0.88–0.95; I2=0%)).

  • The eighth paragraph of the Results should instead state the following:

Eight studies investigated the association between green space and T2DM risk/prevalence. Two studies received a strong quality rating [44, 59]. Five studies observed that a higher availability of green space was associated with lower T2DM risk/prevalence [44, 54, 59, 64, 66] and three studies did not observe an association [42, 53, 60]. In meta-analyses of four studies, more green space was associated with lower T2D risk/prevalence with a pooled-risk ratio of 0.91(95%-CI: 0.88 – 0.95) with an I2 for heterogeneity of 0%.

  • The final paragraph of the Results should instead state the following:

Five studies investigated the association between residential noise and T2DM risk/prevalence. One study received a strong quality rating [82]. Four studies observed that higher exposure to residential noise was associated with increased T2D risk/prevalence [82-85], and two studies did not observe an association [56, 85]. In meta-analyses of three studies [83, 85, 86], higher exposure to residential noise was not associated with T2DM risk/ prevalence (1.95 (95%CI: 0.96 – 3.97), I2 = 44.2%).

  • Figure 1 has been amended and the correct version can be viewed ahead.

  • The heading of Table 3 should instead state the following:

Table 3: Study results of studies investigating the association of physical activity environment, food environment or residential noise with T2D.

  • The caption of Supplementary Table 2 should instead state the following:

Table 3 Study results of studies investigating the association of physical activity environment, food environment or residential noise with T2D
