In a JubLeitter arca pith crude bih rate of 211, what would be the expected number of ANC registrations?
(A) 60 (B) 80 (C) 100 (D) 120
(A) Ans. a. 60In a subcenter area with crude bih rate of 20, the expected number of ANC registrations should be approximately 55.Number of Expected Pregnancies per Year Expected no. of live-bihs (Y)/year= Bih rate (per 1000 population) x Population of the area/1000 Number of Expected Pregnancies per YearAs some pregnancies may not result in a live bih (i.e., aboions & stillbih may occur), the expected number of live bihs would be an under-estimation of the total number of pregnancies. Hence, a correction factor of 10% is required, i.e., add 10% to the figure obtained above.Total number of Expected Pregnancies Z = Y + 10% of YPopulation under the subcentre = 5000Bih rate = 20Expected no. of live-bihs (Y)/year = 20 x 5000/1000 = 100Total number of Expected Pregnancies Z = Y + 10% of Y =100 + 10% of 100 = 110Expected number of ANC registrations will be half of yearly calculation = 55
