Maternal socio-demographic factors associated with low parity and grand multiparity in Nigeria.

Parity may be categorized as low parity (one or two births), multiparity (three or four births), and grand multiparity (five or more births). In Nigeria, studies have examined factors associated with parity among women. However, these studies have focused on the associated factors of grand multiparity with near exclusion of associated factors of low parity. This study addressed this knowledge gap by examining maternal socio-demographic factors associated with both low parity and grand multiparity in Nigeria. The study analyzed secondary data from 2013 Nigeria Demographic and Health Survey (NDHS). The weighted sample size was 25,852 women. With the use of Stata (version 14), analyses were performed at three levels. Multinomial logistic regression was applied at the multivariate level. Results showed that many of the studied maternal characteristics were significantly associated with either low parity or grand multiparity. Results further showed that while late age at first marriage, improved education, never experiencing child mortality, and polygyny increased the likelihood of low parity, improved education, polygyny, never experiencing child mortality, late age at first marriage, and higher household wealth reduced the likelihood of grand multiparity. These factors should be given prominence in population and women-centered programs in the country.
