Better health data with a portable microcomputer at the periphery: an anthropometric survey in Cape Verde

A portable microcomputer was programmed to record anthropometric nutritional data from children aged under 7 years in either a clinic or a population survey situation. An alarm sounds when the anthropometric measurements of a child are below a predetermined value; an immediate check thus avoids the need for subsequent data cleaning and discarding of doubtful information. Data cut-off points in the computer can be adjusted to suit the survey or service needs of the situation. A print-out at the end of the clinic session provides immediate feedback for the staff and a record of the nutritional status of the group. In Cape Verde, 14 670 children attending clinics were surveyed; 26 percent were identified as stunted, 3 percent as wasted, and 1 percent as stunted and wasted. While a portable microcomputer can improve precision, speed and motivation, nutrition surveys still depend on accurate scales, careful measurements and competent staff
