Objective: To determine the prevalence, haematological repercussions and prognosis of childbirth in the event of consumption of kaolin during pregnancy. Materials and Methods: It was a study over a period of 3 months at the Laquintinie Hospital Douala. It compared two groups of women, one of whom had consumed kaolin during pregnancy (exposed group) and the other had not consumed it (non-exposed group). Results: A total of 342 women were included in our study, 121 (35.4%) of whom had consumed kaolin during pregnancy. Women exposed to this consumption (P < 0.05) after univariate analysis were those of pregnant women from the Far North (OR = 3.37, CI: 1.29 -8.79, P = 0.013), single (OR = 1.65, CI = 1.05 -2.59, P = 0.029), those with primary education (OR = 2.25, CI = 1.06 -4.79, P = 0.035) and those with HIV (OR = 2.75, IC = 1.02-7.43, P = 0.045). Consumption was more frequent in the first trimester of pregnancy (37%) and in the third quarter (34%), at a predominantly weekly rate (47.9%). The most frequently cited reasons were envy (82%), and nausea (45%). This consumption was associated with a risk of premature delivery (RR = 2.26, IC = 1.27 -4.05, P = 0.001), yellowish amniotic fluid (RR = 4.66, IC = 1.81 -11, P = 0.001), birth weight < 2500 g in newborns (RR = 1.72, IC = 3.36 -9.56, P = 0.025), but increased the probability of delivery (RR = 1.94, IC = 0.96 -3.90, P = 0.039). For the hematological aspect, the occurrence of anemia (RR = 1.55, IC = 0.97 -2.31, P = 0.003) and a decrease in mean hemoglobin concentration (RR = 1.29, IC = 0.83 -2.03, P = 0.041) were associated with kaolin in pregnancy. After multi- The use of kaolin is a frequent feeding behavior in pregnancy, mainly motivated by envy, which nevertheless presents serious maternal and fetal complications.
