  • Title: Fertility levels among Nigeria's Kanuri.
    Author: Udjo EO.
    Journal: Genus; 1991; 47(1-2):163-76. PubMed ID: 12284820.
    Abstract:
    I 1982, a researcher interviewed 3241 14-50 year old Muslim women of the Kanuri tribe who lived either in 4 villages, in Maiduguri (the state capital), or in the rural village of Marte all in Borne State in northeast Nigeria to learn more about fertility and mortality levels and patterns of the Kanuri, especially the levels and determinants of fertility. The researcher used both the Brass P/F ratio method and the Gompertz relational model to analyze fertility related data. Age reports for females were worse than for males. Further mothers underreported parity. After correcting for these biases and assuming a sex ratio at birth of 103, the male age distributions produced total fertility rates (TFRs) of 4.7 in the villages, 5.6 in Maiduguri, and 5.7 in Marte. The 1984 World Fertility Survey revealed a higher TFR (6.34) for northeast Nigeria than this study's estimated TFR, but completed family size was comparable (5.65) with that of this study. When the researcher compared the estimates with other surveys, he concluded that his estimates were plausible. The fertility levels were low compared to other African countries. He found that Kanuri mothers breast fed for a shorter time, experienced shorter postpartum amenorrhea, and did not have sexual intercourse for a shorter period than women in other African countries. Further they had a very low level of contraceptive prevalence. Thus none of these proximate determinants explained the low fertility of the Kanuri women. Moreover 27% of the women in the villages and 19% in Maiduguri and Marte were infertile at the time of the survey. These levels were higher than infertility levels in neighboring countries. After speaking with physicians an Kanuri leaders, sexually transmitted diseases (STDs) were widespread among the Kanuri. STDs may explain the infertility levels. Yet researchers still need to determine STDs prevalence of among the Kanuri.
