Insights
Anaemia affects over 73% of children under five in Niger, with malaria and febrile infections significantly increasing risk. Interventions must address regional disparities and improve socioeconomic factors for prevention.
Area of Science:
- Public Health
- Pediatrics
- Infectious Diseases
Background:
- Anaemia is a critical global health issue, particularly for children under five in Africa, aligning with Sustainable Development Goal 3.
- The interplay between febrile illnesses like malaria and anaemia prevalence in young children necessitates targeted policy interventions.
Purpose of the Study:
- To analyze the impact of malaria, other febrile infections, and demographic factors on anaemia prevalence in Nigerien children under five.
- To identify key risk and protective factors influencing anaemia in this vulnerable population.
Main Methods:
- Utilized data from the 2021 Niger Malaria Indicator Survey (MIS) under-5 children's module.
- Employed a heteroscedasticity-consistent ordered probit regression model for data analysis.
Main Results:
- A high prevalence of anaemia (73.73%) was observed in children under five.
- Malaria (14.00%) and other febrile infections (33.87%) were significant risk factors, with highest anaemia rates in Tillaberi and Dosso regions.
- Male gender, multiple births, and higher birth order increased anaemia risk, while wealth, age, urban residence, and media access reduced it.
Conclusions:
- Anaemia poses a substantial public health challenge for Niger's under-five population.
- Comprehensive strategies addressing regional, gender, and socioeconomic disparities are crucial.
- Preventing malaria and febrile illnesses, alongside improving household economic status and promoting health education, are key interventions.
Abstract:
Background: The relationship between malaria/other febrile infections and anaemia among under-5 children is a subject of significant policy relevance among African health policy makers. The international significance of addressing anaemia is prominently underscored in the third Sustainable Development Goal (SDG). This paper therefore analysed the effect of malaria/other febrile infections and other maternal and child's demographic variables on the prevalence of anaemia in Niger. Methods: We utilized the under-5 children's module of the Malaria Indicator Survey (MIS) for 2021, which was collected from women of reproductive age (15-49) in selected households. The data were analysed with heteroscedasticity-consistent ordered probit regression model. Results: The results showed that 73.73% of the children was anaemic, while malaria and other febrile infections were present in 14.00% and 33.87%, respectively. Anaemia was highest in the Tillaberi and Dosso regions, where 84.12% and 79.12% of the children were anaemic. The ordered probit regression revealed that anaemia was promoted by malaria, other febrile infections, being a male child, second of multiple birth, and birth order, while wealth index, age, urban residence, and access to newspaper and television reduced it. Conclusions: Anaemia remains a major public health problem among under-5 children in Niger. A comprehensive healthcare intervention to address the problem should consider regional, sectoral, and gender differences in the incidences, with drastic efforts towards prevention of malaria and other fever-inducing illnesses. In addition, interventions to promote households' economic status, reduce maternal fertility, and facilitate preventive practices through nutrition enhancement and health-related media programs hold some promise.
