How to count each binary variables and only generate one variable to include all count information?

Hi there,

I have a set of binary variables and each of them stands for a certain health disease (e.g. heart = heart disease, dep = depression, asth = asthma...).
I also have a variable phi with three values (1, 2, 3) which means three different kind of insurance.

Currently, I want to look at the three insurance distribution, by diseases

I wonder:

1. How to get the number of patients for each disease and put the count information into a new variable count? Or is there an easier way to show how many patients there are for each disease? The below code I tried will overwrite the values of former disease if the respondent has two or more diseases. It cannot calculate the number of patient with a certain disease correctly.

Code:

gen diagnosed=.
replace diagnosed = 1 if heart == 1
replace diagnosed = 2 if dep  == 2
replace diagnosed = 3 if asth == 3
....

2. How to get the insurance distribution by diseases? e.g. for patients with each disease, how many people buy 1st insurance, how many people buy 2nd insurance?


Thanks in advance!
