Two out of every three children in India are physically abused while 53% are sexually abused
This is the first time the government has done such an exhaustive survey on the controversial issue of child abuse.
Abuse of children, particularly sexual abuse, is rarely admitted in India and activists have welcomed the study.
Releasing the report at a press conference in the capital, Delhi, Minister for Women and Child Development Renuka Chowdhury said: "In India there's a tradition of denying child abuse. It doesn't happen here is what we normally say.
"But by remaining silent, we have aided and abetted the abuse of children."
Describing the findings of the study as "disturbing", Ms Chowdhury called for an end to the "conspiracy of silence".
The issue of child abuse has been raised in the past by non-governmental organisations, but this is the first time an attempt has been made by the government to document the scale of the problem.
The study took two years to complete, and covered 13 states where 12,247 children (between five and 12) and 2,324 young adults (over the age of 12) were quizzed.
Dr Loveleen Kacker, the official in charge of child welfare in the ministry, compiled the report.
She said the study had revealed that contrary to the general belief that only girls were abused, boys were equally at risk, if not more.
She said a substantial number of the abusers were "persons in trust and care-givers" who included parents, relatives and school teachers.
Dr Kacker said a disturbing finding of the study had been that 70% had not reported the abuse to anyone.
Besides surveying physical and sexual abuse, the study also collected statistics on emotional abuse and neglect of girls.
The study called for efforts to make society aware of the rights of children and officials say the data will help them formulate better policies to protect children.
