Correlation Analyses Between the Beck Depression Inventory (BDI-II) and the Impact Of

Supplement 1

Correlation analyses between the Beck Depression Inventory (BDI-II) and the Impact of

Weight on Quality of Life (IWQOL-Lite) questionnaire.

This figure displays the Pearson correlation analyses for males (marked green) and for females (marked pink) between the BDI-II and the IWQOL-Lite (i.e., Impact of weight on quality of life) total score (p ≤ 0.017 indicated significance), as well as post-hoc correlations between the BDI-II and the five IWQOL-Lite subscores (i.e., physical function, self-esteem, intimate relations, social embarrassment, and life at work; p ≤ 0.01 indicated significance).

The BDI-II positively correlated with the IWQOL-Lite total score in males and females suggesting a close relationship between the severity of depression and the sense of emotional well-being related to weight. Furthermore, we also found significant correlations with the BDI-II for three out of the five IWQOL-Lite subscores in males (i.e., physical function, intimate relations and life at work) and for two out of the five subscores in females

(i.e, self-esteem and life at work). Note that only the IWQOL-Lite (see Figure 2) correlated with the BMI in both sex, whereas only the females show a positive correlation between

BMI and BDI-II.

Note: sig. = significant, trend = strong statistical trend; n.s. = non-significant

Supplement 2

Correlation analysis between body mass index (BMI) and Beck Depression Inventory (BDI-

The scatter plot displays the sex-specific correlation between BMI and the BDI-II (p ≤ 0.017 indicated significance). The BMI did not correlate with the BDI-II in males, but in females suggesting a female-specific association between the severity of depressive symptoms and an elevated body weight.

Note: sig. = significant, trend = strong statistical trend; n.s. = non-significant

The table lists the coefficients (i.e., effect sizes) and p-values, as well as the thresholds of all the Pearson correlation analyses performed in this study for the whole sample (n = 28).
