Model testing mediation of the association between obesity and perceived weight discrimination by psychological wellbeing (see Figure 2)

	Coeff.	SE	p*	Bootstrap 95% CI	Effect ratio
Total effect (path c)	0.112	0.006	<.001	-	-
Direct effect (path c’)	0.106	0.006	<.001	-	-
Indirect effect (via mediators)	0.0063	0.001	<.001	[0.004; 0.009]	0.056
Indirect effect (via quality of life)	0.0059	0.001	<.001	[0.004; 0.009]	0.053
Indirect effect (via life satisfaction)	−0.0009	0.0005	.072	[−0.002; −0.0001]	−0.008
Indirect effect (via depressive symptoms)	0.0013	0.0007	.067	[0.0001; 0.003]	0.012

Model uses z-scores for all psychological wellbeing variables.

Model is adjusted for age, sex, and wealth.

Coeff. = coefficient; SE = standard error; CI = confidence interval.

^*p values shown for indirect effects are derived from the Sobel test for consistency with total and direct effects, however bootstrap 95% confidence intervals provide a more robust indication of significant mediation (see Method for more details).
