Risk factor for neonatal tetanus in West Burkina Faso : A case control study

A case-control study was carried out to identify risk factors for neonatal tetanus in rural Burkina Faso. Each of the 31 cases identified prospectively were matched with two controls. Risk factors such as the instrument used to cut the umbilical cord and the qualification of the midwives were only identified in the univariate analysis. The multifactorial analysis identified factors commonly believed to be associated with neonatal tetanus: lack of mother's immunization and place of birth other than maternity clinics. However, applying karite nut butter on the umbilical cord was found to be a strong independent factor associated with neonatal tetanus. Immunization of mothers against tetanus should be enforced. Health education must take into consideration sociocultural realities of these populations.
