RESUMO
Two hundred seventy-four healthy Bedouin Arab newborns in 1981 were followed for 18 mo to examine the relationship between infant-feeding practices and growth during planned social change. Although wasting was not prevalent, the prevalence rate of stunting (less than or equal to -2 SDs) increased from 12% to 19% to 32% at 6, 12, and 18 mo, respectively. After multiple-logistic-regression adjustment for covariates, the odds ratio (OR) of stunting at 6 mo was reduced among infants breast-fed only or fed with supplement compared with weaned infants. Infant-feeding practices were not associated with stunting in later infancy; however, those stunted at 6 mo had an OR of 13 of stunting at 12 mo and those stunted at 12 mo had an OR of 14 of stunting at 18 mo. In a multiple-linear-regression analysis, seasonality, duration of breast-feeding, hospitalized morbidity, and residual of height at 6 mo were negatively associated with daily average linear growth from 6 to 12 mo; these factors only explained 12% of the variation in daily linear growth.

Three variants of a Corynebacterium diphtheriae subsp. mitis strain belfanti, two toxigenic (phage types 7 and 11) and one nontoxigenic (phage type 7), were simultaneously isolated from the throat of an adult.
