Anemia in children with Lower tract respiratory infection (LRTI) is a common phenomenon that have crucial role on outcome and quality of life. Proving the observation in our country context, the present study was designed to evaluate the role of anemia as a risk factor among children <5 years along with LRTI.


The case-control study was conducted among 59 childrenaged <6 years and were admitted in Dhaka Shishu (Children) Hospital for the period of June 2019 to November 2019. They study population was divided into two groups where case was defined as- children with LRTI and controls were apparently healthy children. Age and sex matched were done. The study protocol conformed to the ethical guideline of the current Declaration of Helsinki and was approved by local ethics committee. All parents gave consent before participation. Data analysis was done by Statistical Package for Social Science (SPSS) version 22.0.

Observation and Results:

Both case and control group were similar in terms of socio-demographic profile eg. age, sex, residence and socioeconomic status (p value >0.5 for all). Children with LRTI had significantly more anemia than control (83.18 vs 0.09%, p<0.001). Further analysis revealed that anemia is a predictor of LRTI (OR 323.272, 95% CI 19.910-5248.798; p=.001)


Anemia was significantly found to be associated with acute lower respiratory tract infections in children under five years of age. Prevention of anemia, irrespective of etiology, early diagnosis and treatment is important to reduce the incidence of lower respiratory tract infections in children.

Key words:

Anemia, Bronchiolitis, Lower tract respiratory infection, Risk factors.
