Perceptual Factors Associated with Gestational Weight Gain: A Cross-Sectional Survey: Sehee Kim, Sukhee Ahn; J Korean Acad Nurs 2024;54(4):495-508. Published online November 1, 2024; DOI: https://doi.org/10.4040/jkan.24052

Abstract PDF ePub: Purpose
Recent years have seen an increase in the number of pregnant women whose weight gain during pregnancy exceeds the recommended range. This study was intended to determine the relationships among demographic attributes, key perceptual factors, and gestational weight gain (GWG).
Methods
This cross-sectional study was conducted between April and July 2022. First-time pregnant women beyond 36 weeks of gestation who were recruited via social media completed an online survey. Data were analyzed using one-way ANOVA, chi-square test, and logistic regression, all performed using SPSS software.
Results
Of the 369 participants, 63 (17.1%) exceeded the recommended GWG guidelines, while 148 (40.1%) fell within the recommended range, and the remaining 158 (42.8%) had inadequate GWG. Being overweight or obese before pregnancy significantly increased the risk of excessive GWG (p < .001). This risk was also significantly greater for women with low internal weight locus of control (OR = 0.58, 95% CI 0.41~0.82), high external weight locus of control (OR = 1.75, 95% CI 1.31~2.34), and negative body image (OR = 0.62, 95% CI 0.51~0.75).
Conclusion
The growing trend of excessive GWG among pregnant women is influenced by a combination of prepregnancy body mass index (BMI) and perceptual factors, including weight locus of control and body image. These findings underscore the need to implement weight management intervention strategies before pregnancy, taking into consideration BMI, and to enhance positive body image and internal locus of control.

Effect of Lifestyle Intervention Program for Overweight and Obesity Pregnant Women: Choi, Hye Kyung , Kim, Hyeon Ok; J Korean Acad Nurs 2020;50(3):459-473. Published online June 30, 2020; DOI: https://doi.org/10.4040/jkan.19228

Abstract PDF: 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.

Impact of Prepregnancy Body Mass Index on Pregnancy Outcome in Women with a Singleton Conceived by Assisted Reproductive Technology and Spontaneously Conceived Pregnancy: A Case-Control Study: Ju Hee Kim, Hye Sook Shin, Bo Kyung Park, Kwang Moon Yang, Young Ho Lee, Hyun Mee Ryu; J Korean Acad Nurs 2012;42(4):517-524. Published online August 12, 2012; DOI: https://doi.org/10.4040/jkan.2012.42.4.517

Abstract PDF: Abstract Purpose
To compare and confirm the impact of prepregnancy body mass index on pregnancy outcome in women with a singleton conceived by assisted reproductive technology and spontaneously conceived pregnancy.
Methods
A sample of 165 and 247 pregnant women with and without assisted reproductive technology were retrospectively recruited from electronic medical charts of C hospital.
Results
There were significant differences between the two groups for maternal age, paternal age, length of marriage, prepregnancy body mass index, parity, spontaneous abortion experience, and preterm delivery. A prepregnancy body mass index of ≥25 was associated with higher risk for maternal and neonatal complication in the assisted reproductive technology group.
Conclusion
The results indicate that a higher prepregnancy body mass index is associated with increased risks for adverse pregnancy outcomes for women using assisted reproductive technology. So these women need appropriate care to compensate for the risk.
