The present work was planned to study morbidity pattern and nutritional status of a group of healthy new borns in a rural area near Alexandria (Abbis II, VIII villages) through a prospective follow up approach. Eighty two infants were followed up for 12 months. Each infant was subjected to 15 visits within the first year of life. Morbidity was recorded either from mother's history, records from rural health centres or detected by the researcher and expressed as morbidity risk exposures based on a tested scoring system. Anthropometric standards issued by WHO were used to classify the children's length for age, weight for age and weight for length in terms of a cut off point of 2 SD below the median of that of the reference. Gomez classification was used to diagnose undernutrition and Waterlow system was used to diagnose growth stunting. Socioeconomic status of infants' families was also assessed. Results indicated a high prevalence of morbidity risk exposure, growth retardation and under nutrition with a tendency for gradual increase towards the end of the follow up. The results also proved that diarrheal diseases were still the most common illness among infants followed by respiratory tract infections. Investigation of the effects of socioeconomic status on morbidity risk exposure proved its significance at the end of the follow up. The results also illustrated a significant effect of morbidity risk exposure on the nutritional status at the end of the first year.
