運用世界價值觀調查探討越南成年人墮胎態度的決定因素：現代化、宗教信仰與道德寬容度

Abortion remains a globally significant moral and public health issue, shaped by complex interactions among religion, culture, and modernization. Vietnam presents a unique case where abortion has been legal and widely accessible for decades but remains morally contested. Despite extensive international research, few studies have quantitatively examined abortion attitudes in Vietnam or integrated socioeconomic, religious, and moral determinants within a single theoretical framework.This cross-sectional study analyzed data from the World Values Survey (Wave 7, 2017–2020) for Vietnam. The sample included adults aged 18 years and above. Attitude toward abortion (Q184) was the dependent variable. Independent variables encompassed sociodemographic factors, religiosity indicators, and moral permissiveness measures (divorce, premarital sex, euthanasia, casual sex). Logistic regression models were constructed sequentially according to the Revised Theory of Modernisation (RTM), Moral Communities Hypothesis (MCH), and Anti-Ascetic Hypothesis (AAH) to assess their individual and combined effects on abortion attitudes.The majority of respondents (65.8%) regarded abortion as unjustifiable, reflecting prevailing moral conservatism. Socioeconomic factors—including education, income, and urban residence—were not significantly associated with abortion attitudes, suggesting limited influence of modernization. Religious variables showed mixed effects: denominational affiliation and belief in heaven were positively linked to abortion justification, whereas other indicators were nonsignificant. In contrast, all four measures of moral permissiveness—acceptance of divorce, premarital sex, euthanasia, and casual sex—strongly predicted abortion justification (p < 0.001). In the integrated model, moral permissiveness remained the dominant determinant, while the effects of religiosity and socioeconomic status diminished.This study applies an integrated theoretical approach to examine abortion attitudes in Vietnam using nationally representative data. By linking socioeconomic modernization, religious culture, and moral values, the findings aim to advance theoretical understanding of moral change in transitional societies and inform culturally sensitive reproductive health policies.
