Child marriage (before age 18) is a risk factor for intimate partner violence
(IPV) against women. Worldwide, Bangladesh has the highest prevalence of IPV and very
early child marriage (before age 15). How the community prevalence of very early child
marriage influences a woman’s risk of IPV is unknown. Using panel data
(2013–2014) from 3,355 women first married 4–12 years prior in 77
Bangladeshi villages, we tested the protective effect of a woman’s later first
marriage (at age 18 or older), the adverse effect of a higher village prevalence of very
early child marriage, and whether any protective effect of a woman’s later first
marriage was diminished or reversed in villages where very early child marriage was more
prevalent. Almost one-half (44.5 %) of women reported incident physical IPV, and
68.9 % had married before age 18. The village-level incidence of physical IPV
ranged from 11.4 % to 75.0 %; the mean age at first marriage ranged from
14.8 to 18.0 years. The mean village-level prevalence of very early child marriage ranged
from 3.9 % to 51.9 %. In main-effects models, marrying at 18 or later
protected against physical IPV, and more prevalent very early child marriage before age 15
was a risk factor. The interaction of individual later marriage and the village prevalence
of very early child marriage was positive; thus, the likely protective effect of marrying
later was negated in villages where very early child marriage was prevalent. Collectively
reducing very early child marriage may be needed to protect women from IPV.
