How can I identify when and where my subjects ate their food?

The researcher can enter meal codes from 1 to 999. A typical way of using these codes is to set 1 to 9 as the first digit, 0 to 9 as the second digit and 0 to 9 as the third digit. For instance this could make 100 breakfast, 110 breakfast away, 111 breakfast at MacDonalds, etc… of course, any scheme is possible using these 3 digits.
The researcher can enter this data in a table of meal codes which are used to prompt data entry personnel and provide output in validation reports. This table is subject file specific. A meals table can thus be specific to each study.
Meal codes and descriptions appear in all meal detail reports. Meal codes are included in export files and can thus be used in spreadsheets and statistical packages.

Structure – Users

CANDAT is licensed on a per computer basis. CANDAT may be installed on only those computers and networks for which it is licensed. It is possible for multiple users to use CANDAT simultaneously when installed in a network. You are only allowed the number of simultaneous users negotiated in your purchase agreement.

Any one licence (on one computer) can and is allowed to support any number of users. Users are created within CANDAT using a NEWUSER2 creation process. This process creates a folder for the user, specific to the disk (memory stick or other USB device) drive specified at creation. Note that CANDAT records the drive on which the user is created. Users must function on the drive specified at creation in order for CANDAT to be able to function properly. This is particularly important in a laboratory structure where users may connect their memory sticks to a USB port and create their own environment. CANDAT creates an icon with the particulars of the user drive. A user can change the drive in the properties of this icon to correspond to the drive of their memory stick, if used on another computer. For instance, a user could create an environment on their memory stick under the  “F” drive in the laboratory environment and then need to use it on the “G” drive of another computer.

User folders store food files, category files, subject files, questionnaire files, save files, and recipe files.  For a user to use another user’s files, those files must be copied to the relevant user folder. There is no user identification on the files themselves. This structure also allows the same (project) name to be used for each of the food, category, subject, etc. files.

I have used Candat for many years for the analysis of 24 hour recall data, and for the development and subsequent analysis of food frequency questionnaires for two different studies. The range of analytic options provided by Candat, and the fact that it is based on the latest version of the Canadian Nutrient File, are key features.
Assistance with the development of FFQs and translation of responses into the format that can be analyzed with Candat is available on an as needed and timely basis. Response is usually within 24 hours. And, there is no problem asking for help.
I have used Candat for years because of GLI’s knowledge and continuous efforts to make the software ever more powerful.

CANDAT is superior to other nutrient analysis programs because it is designed to accommodate the diverse needs of researchers. Being able to handle food recalls and records and food frequency questionnaires in the same program, to create user files of special food items not included in the CNF and to easily import files into statistical analysis packages makes it unique in Canada. Most of all, having a support person who has extensive experience with nutrition researchers makes CANDAT an easy choice for me.

I have been working with CANDAT since 1984, and have also tried a number of other nutrient analysis programs. I keep coming back to CANDAT for two reasons: the support with CANDAT is superb. I have emailed Gaetan and received a phone call within minutes. He “knows his stuff” and can pinpoint and resolve any problems or challenges quickly. The program he uses to take over the computer is amazing and very efficient.

Since he has worked with a number of academics in nutrition, he understands research and the special needs researchers have. My research group had a challenging task a few years ago which involved adapting an American Food Frequency questionnaire for Canadian use and adding data on dietary nitrates. This was a very complex and time consuming task, and Gaetan was an active participant in the research process. When we were under time pressures to complete the analysis, Gaetan committed time and was able to get us the data when we needed it. He goes beyond a technical role, and sometimes poses questions which I don’t think of, preventing problems before they happen.
