Male involvement in reproductive health care in Viet Nam has been focused on family planning, prevention and care of sexually transmitted diseases. The study explores the factors associated with male involvement in ANC and the utilization of maternal health care services. A cross-sectional survey was conducted among 907 mothers of children under 1 year old between September and December 2013 in the South Central Coast. Thirty two clusters were selected for data collection using structured questionnaire. One third of respondents were the ethnic minorities, the poor, under 25 years old and has primary and lower educations. This study determined the percentage of males who frequently accompanied their partners for ANC (80 percent), looked for health care services (38,6 percent), financial support (61.7 percent) and other cares for pregnant women (76,0). Factors found associated with less frequently accompanied their partners on antenatal visits under secondary level education, among the poor, and aged under 25 years and woman who were the bread winner of the family.
