1-rather felt depressed
pdwrk:1-yes
pdwrk:0-no
indep:age

Variables: pdwrk: Doing last 7 days: paid work: 0-no,1-yes

## Step 1

b0: The log odds of feeling depressed among those who did not do any paid work in the last 7 days is -1,340.

Exp(b0): The odds of feeling depressed among those who did not do any paid work in the last 7 days are 0,262.

b1: The log odds of feeling depressed among those who did paid work in the last 7 days is by 1,088 lower than among those who did not.

Exp(b1): The odds of feeling depressed among those who did paid work in the last 7 days are 0,337 times as low as among those who did not.

b0+b1: The log odds of feeling depressed among those who did paid work in the last 7 days is (-1.340+(-1,088)).

Exp(b0)*Exp(b1): The odds of feeling depressed among those who did paid work in the last 7 days are (0,262*0,337).

Conclusion: Having a paid job has a significant negative effect on feeling depressed.

## Step 2

b0: The log odds of feeling depressed among those who do not have paid work and do not belong to any particular religion or denomination is -1.476.

Exp(b0): The odds of feeling depressed among those who do not have paid work and do not belong to any particular religion or denomination are 0,228.

b1: The log odds of feeling depressed among those who have a paid job everything else hold constant is by 1,066 lower than among those who have paid work.

Exp(b1): The odds of feeling depressed among those who have a paid job everything else held constant are 0,344 times lower than among those who have paid work.

b2: The log odds of feeling depressed among those who belong to a particular religion everything else held constant is by 0,265 higher among those who do not.

Exp(b2): The odds of feeling depressed among those who belong to a particular religion everything else held constant is 1,303 times as high as among those who do not.

Conclusion: Having a paid job has a significant negative effect on feeling depressed.

## Step 3

b0: The log odds of feeling depressed among those who do not have paid work, do not belong to any particular religion, and are 0 years old is -2,860.

Exp(b0): The odds of feeling depressed among those who do not have paid work, do not belong to any particular religion, and are 0 years old are 0,057.

b1: The log odds of feeling depressed among those who had paid work in the past 7 days everything else held constant are by 0,687 lower than among those who did not.

Exp(b1): The odds of feeling depressed among those who had a paid work in the past 7 days everything else held constant are 0,503 times as low as among those who did not.

b2: The log odds of feeling depressed among those who belong to a particular religion everything else held constant is by 0,016 higher among those who do not.

Exp(b2): The odds of feeling depressed among those who belong to a particular religion everything else held constant are 1,016 times as high as among those who do not.

b3: The log odds of feeling depressed for the respondent increases by 0,026 every life year, everything else held constant.

Conclusion: At the beginning the b1 was significant and it remained significant even after controlling for religion and age of the respondent. It is interesting to see that in step 2 the effect of belonging to a religion was just out of the significance tolerance level (p=0,066) but in step 3 the effect was eliminated by age (p=0,916). It may indicate that it is not the religion but the person’s age has an effect on feeling depressed.
