Purpose: To identify group-specific policy implications for women facing crisis pregnancies, this study compared research trends across three decades (2000s, 2010s, 2020s) concerning unmarried mothers and women with disabilities.Methods: Studies published between 2000 and 2025 were collected from the RISS (domestic) and PubMed (international) databases. Keyword frequency, bigram, TF-IDF (term frequency-inverse document frequency), and LDA (Latent Dirichlet Allocation) topic modeling were applied to extract major themes by group and by decade.Results: Domestic studies on unmarried mothers revealed thematic shifts such as “teenage pregnancy and adoption”; “childcare, support, and discrimination”; and “independence, rights, and social responsibility.” International studies consistently emphasized such medical issues as “maternal health, child health, and risk.” Research on women with disabilities showed different foci: domestic studies highlighted reproductive health and rights, whereas international studies concentrated on physical health risks.Conclusion: Policies for women facing crisis pregnancies should move beyond uniform support and adopt tailored approaches that reflect group-specific characteristics and sociocultural contexts. Furthermore, the temporal evolution of research topics reflects social and institutional changes, underscoring the need for policies that balance health and welfare.
