Abstract.
Pneumonia remains one of the leading causes of morbidity and mortality among
children under 5 years of age, particularly in low- and middle-income countries. Despite
numerous studies, data on differences in the clinical course of pneumonia between full-term and
preterm infants under 1 year of age are still limited.

Relevance.
Pneumonia remains one of the leading causes of morbidity and mortality
among children under 5 years of age worldwide, particularly in low- and middle-income countries.
Despite numerous studies examining differences in the clinical presentation and outcomes of
pneumonia across various pediatric age groups, comparative data on the course of the disease in
full-term and preterm infants under 1 year of age remain limited. Given the high prevalence of
pneumonia in this age group, assessing differences in the severity of clinical manifestations
between full-term and preterm infants is essential for optimizing patient management and
improving treatment outcomes. This study was designed to address this gap.
Objective.
To compare the clinical features and course of pneumonia in full-term and
preterm infants under 1 year of age. The analysis included fever intensity, duration of
hospitalization, frequency of admissions to the intensive care unit, and oxygen saturation levels.
Materials and Methods.
This retrospective study included 60 infants under 1 year of age
hospitalized at ARDMMC with a diagnosis of community-acquired pneumonia between January 1
and December 31, 2022. Patients were divided into two groups: preterm (gestational age ≤34
weeks, n=30) and full-term (gestational age >34 weeks, n=30). The parameters assessed were
div temperature, length of hospital stay, frequency of ICU admissions, and oxygen saturation
(SpO₂). Statistical analysis was performed using the t-test, with p<0.05 considered statistically
significant.
Results.
The mean age of the preterm group was 6.1±3.2 months, while that of the full-
term group was 7.2±2.9 months (p=0.134). Preterm infants had higher fever (39.1±0.6°C)
compared with full-term infants (38.7±0.5°C, p=0.022). The duration of hospitalization was also
longer in preterm infants (8.6±2.4 vs. 7.4±1.9 days, p=0.012). ICU admissions were more frequent
among preterm infants (60% vs. 30%, p=0.031). In addition, preterm infants had lower oxygen
saturation levels (91.5±1.9% vs. 95.2±1.2%, p<0.001).
Conclusion.
Pneumonia in preterm infants under 1 year of age follows a more severe
clinical course compared to their full-term counterparts. It is characterized by higher fever, longer
hospitalization, a greater need for intensive care, and lower oxygen saturation levels. These

findings underscore the need for closer monitoring and timely treatment of preterm infants to
prevent complications and improve prognosis. In clinical practice, the identified differences
should be considered when managing pneumonia in infants.
