Misuse of antenatal care and its association with adverse outcomes of pregnancy in a Southern rural area of Vietnam

ABSTRACT

Researchers in Vietnam reported a high percentage of pregnant women attending ANC at least once, but an insufficient utilization of ANC services remains. The evidence demonstrating how the utilization of these services affect pregnancy outcome is not documented in Vietnam. We investigated the association between the misuse of ANC services and pregnancy outcome, and assessed other determinants associated with ANC services utilization. We conducted a prospective community-based study in Trang Bom district, Dong Nai, during 12 consecutive months. Data were collected using a structured questionnaire and medical records. Women were followed up to delivery. Misuse of ANC services, related factors and its association with adverse events were assessed using logistic regression. Out of 3301 pregnant women, 91% initiated an ANC visit within first trimester, 95% attended at least three ANC visits, but a low percentage of pregnant women underwent blood and urine tests at least once (20% and 39%, respectively). Factors significantly associated with a higher risk of adverse outcomes were lack of blood test and urine test, parity ≥ 3, ANC visits < 3, history of an adverse outcome, and having a clinical condition. Blood and urine tests were less frequently used by young women, women from ethnic minorities, women using only private facilities for ANC attendance, and women with a low number of ANC visits. Despite a high percentage of early entry into ANC and of at least three ANC visits, misuse of ANC services still exists and contributes to adverse outcomes. There is a need to increase the awareness of women on the benefits of ANC services by educating young women as well as women with several children. Health workers should be encouraged to propose suitable ANC services to pregnant women.
