Hi

I don't think that there is a causal relationship. We should always be cautious with the interpretation of correlations...

There is a huge relationship between poor health (observed or reported !) and social status, economic status, education level. This is called the socioeconomic gradient of health.

And as there is a relationship between poor literacy (in general and in health) and these statuses, you've gor yur relationship. So it is probably not causal (not directly anyway) but it is an interesting indicator.

Hope I've helped

Hi Alain,

You ´are right. I wrote causal relation in the title but the right one is associations. I changed the title of the question.

Thank you for your response.

Fabio, do you mean literacy (ie. school education) or health literacy ( the capacity to understand basic health information and services to make appropriate health decisions)?

Hi Dear Dr. Laverack.

My question is about health literacy.

I'll apreciate your opinion.

Thank you.
