This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue and pregnancy stress, blood pressure, and neonatal birth weight, using Cox's interaction model of client health behavior for overweight and obese women.
This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52 patients 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. The lifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, and professional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017.
This study showed differences in the appropriate weight gain rate (χ²=6.17, =.013), suppression of an increase in fatigue (t=-2.32, =.012), and an increase in pregnancy stress (t=-1.87, =.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birth weight (>.05) were found.
The study findings indicate that this program could be an effective intervention for the control of appropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox's interaction model of client health behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.
本研究旨在利用考克斯（Cox）的超重和肥胖女性客户健康行为交互模型，确定生活方式干预计划对体重增加、饮食习惯、疲劳和妊娠压力、血压以及新生儿出生体重的影响。
这是一项采用非等效对照组前后测设计的准实验研究。共有52名符合入选标准的患者参与研究，其中实验组25人，对照组27人；她们均为在J省A和B两家和B医院接受产前护理的超重和肥胖孕妇。生活方式干预计划共持续12周，包括情感支持、健康信息以及专业/技术能力等方面的互动。数据收集期为2017年2月1日至2017年8月31日。
本研究显示，在适当体重增加率方面存在差异（χ²=6.17，P =.013），疲劳增加得到抑制（t=-2.32，P =.012），妊娠压力增加（t=-1.87，P =.034）。然而，在身体活动、饮食习惯变化、血压和新生儿出生体重方面未发现差异（P>.05）。
研究结果表明，该计划可能是控制适当体重增加、疲劳和妊娠压力的有效干预措施。因此，基于考克斯客户健康行为交互模型的生活方式干预计划可能是超重和肥胖孕妇获得积极健康结果的有效策略。
