[Postpartum depression: prevalence and risk factors. A prospective Study concerning 302 Tunisian parturients]

Depression is a common condition especially in the postpartum. It exposes mothers, newborns and couples for psychosocial complications.

They were to estimate the prevalence of the depression in postpartum in a population of 302 Tunisian parturients and to identify its associated factors.

Our study was prospective, in two stages: at the first week (T1), then between sixth and tenth week of the postpartum (T2). The study was conducted at CHU Hédi Chaker in Sfax, Tunisia. We used the Arabic version and validated the Edinburgh Postnatal Depression Scale (EPDS) for screening for postpartum depression. We used the scale MSSS. "Maternity Social Support Scale"to assess the social and family support and the Azrin scale to evaluate the satisfaction of the conjugal relationship. An epidemiologic questionnaire was used to collect the sociodemographic and clinical data.

At T1, 302 women were examined. At T2, 139 were reexamined (46% of the initial population). In the first stage, the prevalence of the intense postpartum blues, according to EPDS, was 19,2%. In the second stage, the prevalence of the postnatal depression was 12, 9%. Factors associated with postpartum blues intense were the low socioeconomic status (p =0, 01), a lower educational level (p = 0,017), the poor marital relationship (p =0, 04), an insufficient social support (p 0,001), the difficulty to accept pregnancy (p =0,001), the presence of psychiatric the presence of psychiatric history (p =0,001), the prematurity (p =0,001) and an ill newborn birth (p =0,001). Factors associated with the post natal depression were the low socioeconomic status (p =0,01), the poor marital relationship (p =0,034), difficulty with pregnancy (p =0,001) and the presence of psychiatric history (p =0,001).

Postpartum depressions are common. It seems to be the result of the interaction of several biological, psychological and social factors. This suggests the importance of screening for women having such risk factors to prevent the installation of this depression. This detection should be done early in postpartum or else in the later postnatal consultations. This allows an adequate treatment for the mothers, for the relationship mother-new born and later, for the psychological equilibrium of the child.
