How to control variables in logistic regression?

[natasha_nf]

Hi,

I'm trying to perform 2 logistic regressions controlled for some variables.

exposure: quartiles of processed food consumption

outcome model 1: binary depression (yes or no)

outcome model 2: mental disorders (4 disorders)

confoundings: (categorical and numerical) sex, age, education, etc.

Could anyone help me with the code?

Thank you in advance.

Here's an example of nominal regression:
