Background: The aim of this study was to describe the epidemiological profile of childhood respiratory tract diseases (RTD) in the region of Sfax, Tunisia, and to evaluate their trends over a 13 year period.
Methods: We conducted a retrospective study of all children hospitalized with RTD aged under 14 years. We collected data from the regional morbidity register of the university hospital of Sfax from 2003 to 2015.
Results: A total of 10 797 RTD patients were enrolled from 49 880 pediatric hospitalizations (21.7%). A male predominance was noted (60%). The median age was 8 months (IQR, 2-36 months). Acute bronchitis (AB) accounted for 53.8%, followed by asthma (15%), pneumonia (14%) and acute upper respiratory infection (AURI; 7.2%). The hospital incidence rate (HIR) of RTD was 34/10 000 inhabitants/year. It was 18.2; 5.07; 4.7 and 2.4/10 000 inhabitants for AB, asthma, pneumonia and AURI, respectively. We noted a significant increase in the HIR of RTD with an annual percentage change (APC) of 10.94% (P < 0.001); in the HIR of AB (APC, 5.27%; P < 0.001); and in asthma HIR (APC, 11.2%; P < 0.001). Otherwise, a significant decrease in AURI HIR was observed (APC, -8.8%; P < 0.001). AB lethality rate increased significantly, with an APC of 7.4% (P < 0.001). Projected trends analysis up to 2024 showed a significant rise in AB and in asthma, while AURI would significantly decrease.
Conclusions: RTD continues to be a serious health problem over time in terms of morbidity and mortality. Preventive and curative strategies are needed urgently.
