After the experiences at the individual sites during the Reconnaissance project had been presented in a plenary format, five groups were formed. Four of these groups examined the individual questions on the original questionnaire with specific attention to (1) nutritional status and biological variables, (2) food intake and food security variables, (3) health status assessment variables, and (4) lifestyle, socio-demographic, and social behaviour and practices variables. In this process, the groups identified items on the questionnaire that had been found, at one or another site, to be of doubtful appropriateness or feasibility. The area of concern of the fifth group was the sampling frame and selection procedures for sites and individuals within sites.
