VALIDITY AND EPIDEMIOLOGY OF REPORTED POOR APPETITE AMONG PERUVIAN INFANTS FROM A LOW-INCOME, PERIURBAN COMMUNITY

To assess the validity of maternal reports of poor infant appetite, th ese histories were compared with measured energy consumption on 1621 d of observation of 131 Peruvian infants in a low-income community. Mea n (+/-SD) total energy intakes on days with reported anorexia were 338 +/- 88 kJ/kg body wt in infants 1-6 mo of age and 299 +/- 92 kJ/kg bo dy wt in infants aged >6 mo compared with 395 +/- 92 and 342 +/- 88 kJ /kg body wt in the respective age groups when appetites were reportedl y normal (P < 0.001). Energy intake from non-breast-milk sources was m ore affected than energy from breast milk. The epidemiology of poor ap petite was assessed in 153 infants who were monitored longitudinally d uring their first year of life. The prevalence of reported anorexia in creased progressively from 22 to 317/1000 d of observation from <1 to 11 mo of age. Infant age and the presence of fever, diarrhea, and resp iratory illnesses were each associated positively, and consumption of breast milk was associated negatively with the presence of reduced app etite. Poor appetite, rather than lack of food, may explain in part th e low energy intakes by infants in this community.
