A Literature Review on Perceptions and Practices Related to Healthcare and Nutrition Amongst the Residents of Urban Slums Across India

Urban regions are home to more than a billion people worldwide; by 2030, more than half of the world's population is projected to reside there. Many rural residents relocate to urban regions in pursuit of employment, better living conditions, and access to healthcare facilities. The study’s primary objective is to collate the findings related to perceptions, knowledge, attitude, and practices from studies across the urban slums in India related to healthcare and nutrition. A systematic search of articles was conducted on the National Library of Medicine PubMed Portal Google Scholar, and J-Stor databases for published studies across the indexed journals. Academic social media sites like Academia.edu and Researchgate.org were also searched for grey literature. The inclusion criteria include studies conducted in Urban slums from 2010 to 2022, conducted amongst the Indian population within the Indian Geography, and focusing on documenting perceptions, knowledge, attitude, and practices. Exclusion criteria were cross-sectional surveys with quantitative questionnaires focusing on the prevalence of diseases and the burden of risk factors, literature reviews, systematic reviews, frameworks for implementation of specific interventions, and experimental study designs. A total of 18 qualitative observational studies were included in the review and the findings related to knowledge, attitudes, and practices identified from the literature were summarized. The literature indicated adequate knowledge about nutrition and healthcare, and the barriers towards transitioning knowledge to practice were related to lack of resources, priorities around employment and income, and the attitudes towards change-making were usually based on convenience to access cost of service and availability of the services. The review recommends further investment in research to understand the perceptions, patterns of nutrition, and health-seeking behaviours. Also, there is a pressing need to use the evidence for developing policies in line with the expectations of poor urban communities.
