Ouham-Pendé: a new endemic goiter area in the Centroafrican Republic (CAR): epidemiological survey on 7621 subjects.
The authors report epidemiological observations about a new endemic goiter area in the North western region of the Centro-African Republic (CAR). The research was carried out in 7 quarters of the chief-town (Bocaranga) and in 8 rural villages; 7621 people were examined by the same three of the present Authors who filled in a sample individual form (proposed by WHO) with the generalities and the goiter grading. The data were analyzed according to sex, age and place of residence by means of the common position parameters and the cumulative frequencies, taking into account the goiter grading of each group. The goiter prevalences observed in the rural areas varied from 70.9% (males) to 82.6% (females), whereas in the chief-town they varied from 29.3% (males) to 57.9% (females). Neurological and myxedematous cretins were seen to constitute 3.4% of the visited population. The M/F goitrous ratio was near unity under the age of 6; above this age, females are more widely and severely affected than males. An important fall in goiter prevalence was observed in adult males after the age of 16. The gradings observed in the rural villages, in both females and males of different ages (0-5; 6-15; 16-45; greater than 45 ys.) were significantly more severe than those observed in the chief town (P less than 0.01). The results obtained confirm those of a preliminary survey which the Authors previously carried out on a sample of school children living in the same region of CAR.
