This scoping review aimed to map and synthesize the existing literature to explore the scope of research on the prevalence and predictors of malnutrition (underweight, obesity, and anemia) among WRA in Nepal. A comprehensive search was conducted using several databases, including MEDLINE, DOAJ, CINAHL, and NepJOL, covering studies published between January 1, 2000, and June 15, 2024. Studies reporting the prevalence and/or predictors of undernutrition, obesity, or anemia among women aged 15-49 years in Nepal were included in this review. The exclusion criteria were studies focusing on disease-specific malnutrition, review articles, and clinical trials. Studies relying solely on secondary analyses of Nepal Demographic and Health Survey (NDHS) data were excluded to prevent duplication of estimates. A total of 1448 records were retrieved, and 751 duplicates were removed, leaving 697 records for screening. After excluding 577 records at the title/abstract stage, 120 full texts (including 6 from citation searching) were assessed, and 16 studies met the inclusion criteria. The prevalence of underweight ranged from 2.0% to 30.3%; overweight/obesity ranged from 4.8% to 55.0%; and anemia ranged from 12.83% to 66.8%.
