Frequency table for multiple variables

[Brenda de Kok]

Dear all,

As a fairly new user of Stata, I would appreciate any suggestions to create a frequency table of my data. I have already searched through the forum and Google, but I cannot seem to figure out a solution.

I have developed a questionnaire to ask people how often they have consumed foods from a certain food group (my variables). They can indicate: 0 (never), 2, 4, 13, 14 or 30 days (each day) over the past month.

To make it simple, my dataset looks similar to this:
Variables: 1_grains, 2_meat, 3_vegetables (etc.)
Response categories: 0, 2, 4, 13, 24, 30
n = 80.

Now I would like to know how many of my respondents have consumed at least 2 days of the month (response category ≥2) a food from a food group. I can do this one by one with tabulate:

. tab 1_grains if 1_grains > 0

So 77 out of 80 people have eaten a food from the food group "grains". So I can either do this all manually, but I assume there must be an easier way, to create something like this:

Food group	n (days consumed > 0)	Percentage
1_grains	77	96%
2_meat	30	38%
3_vegetables	45	56%

A next step would be to put these percentages in a graph, but if I can get the numbers and percentages into a table that would already be great.

Thanks in advance for any help on this!

Kind regards,
Brenda
