Introduction: Low birth weight is defined as a birth weight of less than 2500g. Constitutes a major public health problem in the word due to its magnitude and its strong association with neonatal mortality and mobility.
Methods: We conducted a descriptive and analytical prospective study, covering the period from 01/01/2020 to 12/31/2020 from the technical sheets developed by us and validated by the department.
Results: 359 cases of low weight were recorded out of 972 babies admitted to the neonatology department, i.e a prevalence of 36.9%. The various risk factors for low birth weight (LBW) were in our series, the young age of the mother (those aged 17 gave birth more LBW), maternal infections (67.4%), less educated mothers (51.5%), primiparous (64.6%) and those who had not done ANC (61%).
Conclusion: In our series, mothers under the age of 18, maternal infections, primiparity, less educated mothers and lack of CPN follow-up are the factors associated with LBW.
