Abstract
This quasi-experimental study employed a two-group posttest-only design to compare the mean score of food and iron supplement consumption behaviors and hematocrit levels between an experimental group and a control group following the implementation of a nutrition-focused health promotion program combined with home visits. The sample consisted of 60 pregnant adolescents receiving antenatal care at Prathai Hospital, selected through convenience sampling. The experimental group (n = 30) received the nutrition health promotion program and home visits in addition to routine nursing care, while the control group (n = 30) received only routine nursing care. Research instruments included a personal information form and a questionnaire on food consumption and iron supplement intake, with Cronbach’s alpha coefficient of .78. The data were analyzed using descriptive statistics and independent t-tests.
The results showed that the experimental group had significantly higher mean scores in food consumption behaviors and iron supplement intake than the control group (t = 7.76, p < .001). Additionally, the experimental group demonstrated significantly higher hematocrit levels compared to the control group after the intervention (t = 5.59, p < .001).
These findings suggest that antenatal care nurses can effectively apply a nutrition-focused health promotion program combined with home visits to support pregnant adolescents. This approach provides context-sensitive care and promotes health understanding, thereby encouraging appropriate self-care behaviors during pregnancy.
