Figures from Women's Aid show there were more than 19,000 contacts to the domestic abuse support service in 2016, with nearly 4,000 disclosures of child abuse.
The 2016 annual report is the first since the service's helpline began operating 24 hours.
During the 19,115 contacts made to the service, 16,946 disclosures of domestic violence against women were noted, while there were an additional 3,823 disclosures of child abuse.
96% of callers to the Women's Aid 24-hour Helpline were women and 4% were men.
The majority of the women say they were being abused by a current or former male intimate partner.
The report shows that there were more than 11,000 reports of emotional abuse such as stalking and isolation from family and friends, 3,500 disclosures of assault and nearly 700 reports of rape.
This year’s report has a particular focus on the impact of access arrangements for children in the case of a separation.
Last year, there were more than 400 reports from mothers that their former partners were using access visits to abuse them - often in front of their children.
The organisation also recorded 82 reports where children were being physically, emotionally and/or sexually abused while on access visits with their fathers.
