It included three domains: Other Urban Areas, Rural Areas, and Metropolitan Lima and Callao. The sample included 1296 clusters, of which 176 were in Metropolitan Lima and Callao, 696 in urban areas, and 424 in rural areas. \n\nThe clusters were selected through a systematic sampling method with a random start and with probability proportional to the adult population size.  The dwellings were also selected systematically with a random start. Sample size calculations were carried out independently for each study stratum. The calculations were based on the prevalences of anemia and overweight from previous studies, with a margin of error ranging from 4.3 percent to 8.5 percent, an expected non-response rate ranging from 10 percent to 13 percent, and a confidence level of 95 percent.","coll_mode":["Face-to-face [f2f]"],"sources":[{"name":"","origin":"","characteristics":""}],"coll_situation":"A 24-hour dietary recall interview was conducted in the adults' household.","weight":"The weighting factor was calculated considering the following: \n1.
