Using the Nutrition Form

After the Nutrition Form is opened, data can be entered, modified, and deleted in the same manner as other Epi Info™ 7 forms. Each record in the Nutrition form represents a single child. The form contains the optional capability to geocode the child’s home address into latitude and longitude coordinates with the Get Coordinates button. Reference the Enter Data section of this user guide for additional information regarding the data entry process.

Although the data entry form contains only one record per child, each child may have been measured at multiple points in time. The Nutrition project has the ability to capture multiple measurements for each child, which is essential for calculating statistics and generating graphs. The Nutrition form has a related form called PatientVisits to store measurement information over time. The PatientVisits form may have one or more associated records. Clicking the Enter Measurement Data button will access the PatientVisits form.

Figure 11.3: PatientVisits Form

The patient’s name, sex, date of birth, and ID number automatically appear in the form. These values link the records in this form to the child’s nutritional record in the Nutrition form. As you type values into the PatientVisits form (e.g., date of measurement, age in months, height, weight, etc.) the z-scores and percentiles are automatically calculated and appear in the form.

Add measurement records by clicking the New Record button on the toolbar. Clicking the <- Back button closes the PatientsVisits form and returns you to the Nutrition form.

The relationship between these two forms defines how information is stored and calculated. For each record in the Nutrition form, there may be one or more linked record(s) in the PatientVisits form. If the user is viewing record #1 in the Nutrition form, clicking the Enter Measurement Data button will take the user to all of the measurements associated with that particular child (and no others). See the following figure for a visual explanation of the relationship. Note that the blue squares represent records in the Nutrition form, and the red squares represent records in the PatientVisits form.

To view Child #1’s measurement information on 12/15/2001, navigate to Child #1’s record in the Nutrition form. Click Enter Measurement Data and navigate to the record that has 12/15//2001 as the date of measurement.

Note: The data included in the Nutrition project may differ from that displayed in the figure above.

Customizing the Nutrition Forms

The Nutrition forms can be customized to include or exclude any field or check code in the form. For example, if geocoding the child’s address into latitude and longitude is not necessary, those fields can be deleted. The form’s title, Nutritional Survey, can also be changed.

Note: Removing fields or changing field names may disable the underlying z-score and percentile calculations.

For additional information regarding form editing, reference the Form Designer section of the user guide.
