BackgroundTeenage pregnancy is a concerning public health problem in India. Misperception and misunderstanding about pregnancy and its preventive methods lead to pregnancy when adolescents are involved in unsafe sexual intercourse. This scoping review aims to discuss the evidence on the perception, practices, and understanding related to teenage pregnancy among adolescent girls in the Indian context.MethodThe Arksey and O'Malley scoping review framework and Joanna Briggs Institute Reviewers’ Manual were used for the scoping review. The Population, Concept, and Context strategy (PCC) ensured the review questions, eligibility criteria, and search strategy. The Systematic Review and Meta-analysis: Extension for Scoping Review (PRISMA-ScR) was used. A literature search was done using electronic databases by specific keywords such as “teenage”, “adolescences”, “pregnancy”, “perception”, “knowledge”, “awareness”, etc. Relevant grey literature was identified through further searching. The review included studies that fulfil inclusion criteria having female adolescent groups aged from 10 to 19 years in the Indian context between the years 2000 and 2021.ResultWe found 40 eligible studies; more than half of these were from southern (35%) and northern (27.5%) regions, and studies from the rest of India were very sporadically distributed. Most studies (72.5%) were published in the last 10 years. The relevant extracted data from individual studies were synthesized and presented in the two major sections, perception, practices, and the second one, understanding and experiences among teenage girls. The understanding of pregnancy and teenage pregnancy-related preventive methods was detailed analysis in about 72% of papers whereas other aspects, such as perception (22.5%), practices (25%), and experiences (7.5%) were discussed in the remaining papers related to pregnancy among adolescent girls.ConclusionEvidence in the selected studies shows that understanding and practices are the major areas that were primarily explored, where perception, practices and experiences are the topics that are relatively less investigated. Literature synthesis derives misconception, lack of understanding, and practices without knowing the consequences are the key factors responsible for early pregnancies. Future interventions like increasing awareness, providing comprehensive reproductive knowledge, convenient health care aids, and proper counselling are adequate measures for minimalising the problem. The present analysis showed that studies are limited in their scope concerning various aspects of teenage pregnancy in India, so this scoping review gives essential perspectives on future research and implementation plans and policies in this field.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12978-023-01634-8.
