Abstract

Purpose
This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue andpregnancy stress, blood pressure, and neonatal birth weight, using Cox’s interaction model of client health behavior for overweight andobese women.
Methods
This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52patients who met the selection criteria, including 25 in the experimental group and 27 in the control group, were the subjects of the study;they comprised overweight and obese pregnant women who were receiving prenatal care at A and B women’s hospital in J province. Thelifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, andprofessional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017.
Results
This study showeddifferences in the appropriate weight gain rate (x²=6.17, p=.013), suppression of an increase in fatigue (t=-2.32, pp =.012), and an increasein pregnancy stress (t=-1.87, p=.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birthweight (p>.05) were found.
Conclusion
The study findings indicate that this program could be an effective intervention for the control ofappropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox’s interaction model of clienthealth behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.
