Pathways that determine the fertility of sedente and migrant Oraon populations of Eastern India: a structural equation modelling approach

Abstract

Within local socio-ecological context, the fertility determinants of a population are mediated through complex interrelated physiological and behavioural pathways. We aimed to find out the direct and indirect determinants of fertility of sedente and migrant Oraon populations using Structural Equation Model (SEM). Bivariate analysis showed significant (p ≤ 0.05) sedente-migrant differences in socio-demographic, reproductive, contraceptive, and reproductive and sexual decision-making variables. Results of SEM showed migration status, age at first conception, contraceptive preference and reproductive and sexual decision making have direct but negative association (p ≤ 0.05), and age of the participants, under-five mortality and preference for male child have direct but positive association with fertility (p ≤ 0.05). These variables are also associated with fertility through certain mediated pathways (p ≤ 0.05) like ages at first conception with contraceptive preferences, reproductive and sexual decision-making ability (positive), under-five mortality and desired family size (negative). Educational status of the spouses showed indirect association (p ≤ 0.05) with fertility through four pathways: (i) contraceptive preferences; (ii) reproductive and sexual decision-making ability; (iii) ages at first conception (positive); and (iv) desired family size (negative). Hence, sedente and migrant participants reflected a sharp difference in the determinants of fertility owing to differential local socio-ecological attributes.
