Abbreviations: OR, odds ratio; CI, confidence interval; AOR, adjusted odds ratio.
a
Values are given as mean ± SD (range) or number (percentage).
b
Age ≥18 years used as a reference relative to the minor age at marriage category in multinomial analyses (e.g. participants who were not consulted in mate selection, relative to those who were consulted, were more likely to marry at <15 years rather than at ≥18 years).
c
Age variables are presented as means descriptively, but were used as continuous variables in regression.
d
P<0.05.
e
P<0.001.
f
P<0.01.
