Reviewer's repo rt: 
 
I appreciate the opportunity to review the manuscript on 'Intimate Partner Violence and 
Contraceptive Discontinuation among Sexually Active Married Women in Nigeria' by Kupoluyi 
Joseph Ayodeji. The study addresses a very important factor in contraceptive adherence among 
married women who are at risk of being pregnant. This is a well written manuscript which can be 
further improved upon if the observations noted below are addressed as appropriate.

have discontinued contraceptive although …  
Line 29 ''…. A number of living children', …'should be 'The number of living chi ldren, ..  
Line 31 between discontinue and even although it seems a word is missing. It should read: ''..

Line 35 A word is missing between prevalence and rate. It should read: This study concludes that 
program ta ilored towards increasing contraceptive use prevalence rate

Lines 52/53  Husband aged sixty and above (60+) are 3.17 times more likely to discontinuation 
while still at risk of becoming (it should read:  Wives whose husbands are aged sixty and above

feebly. (Change 'feebly' to 'feeble')  
 
DISCUSSION  
All statistical annotations such as  (p &lt;0.05),  (aOR = 1.78, p &lt; 0.05) should be removed 
from the discussion to facilitate easy reading

Line 33 experience on how to avoid pregnancy than those who married less than four years.  (It

CONCLUSION  
Lines 53 -55 Findings revealed that women's occupation, number of living children and marital 
duration significantly influenced women who have experienced any form of IPV to have 
discontinued contraception while still at risk (Rephrase as: Findings revealed that women who 
have experienced any form of IPV were significantly influenced by their occupation, number of 
living  children and marital duration to discontinue contraception while still at risk)  
What is already known about this subject?   
Lines 39 -40 Little is known on the relationship between contraceptive discontinuation and 
experienced Intimate Partner Violence (IP V) among sexually married women in Nigeria.
