Self-reported morbidity and its conditionings in children 5 to 9 years old in Sobral, CE, Brazil

This study was based on a random sample of 3,276 children aged between 5 and 9 years from the urban region of Sobral - CE, Brazil.

The main goal was to describe reported morbidity in children aged between 5 to 9 years and to analyze their conditionings.

Home interviews were carried out with 3,276 children and clinical exams were conducted in a sub-sample of 2,594. Health problems reported by mothers were classified according to the tenth revision of the International Disease Classification. Analyses were performed using Stata 7.0. Outcomes analyzed were reported morbidity in the past 15 days. The independent variables were grouped into socioeconomic, environmental, health service access, and nutritional status.

The most prevalent morbidities were diseases of the respiratory system (DRS), 28.7%; diseases of the skin and subcutaneous tissue, 3.4%; infectious and parasitic diseases, 2.2%. The independent variables that had statistically significant correlations with the prevalence of DRS were related to the children who lived in the main urban center, had a history of malnutrition, and low school attendance, with odds ratio of respectively, 1.48 (1.10-1.9995%CI), 1.30 (1.05-1.6095%CI), 1.54 (1.02-2.3295%CI).

A high prevalence of DRS was observed in children in the main urban center. DRS prevalence was about twice higher than that observed in other studies with similar methodology. This observation has raised the hypotheses of over reporting or environmental pollution. Most children had minor health problems. They also had facilitated access to health services, especially to the FHP.
