Outline of Final Research Achievements

The objective of this study was to examine the relationship between pregnant women’s lifestyle, perinatal outcome and their body proportions with “masked obesity” [body mass index (BMI) <25 kg/m2 and body fat percentage≧30%], those with standard proportions [BMI: 18.5-24.9 kg/m2 and body fat percentage＜25%]. In 81 pregnant women aged 20 to 43 years were examined for body type measurement using a body composition analyzer and their lifestyle was surveyed a self-administered questionnaire.
Twelve subjects (14.8%) were masked obesity, and the standard proportions were 21 (25.9%) subjects. There was no difference in the frequency of their any lifestyle. There was also no difference in the type of delivery styles and weight of newborns. Since 12 (20.7%) of the 58 normal weight pregnant women were masked obesity, it is considered that measurement of body fat percentage as well as body weight is necessary as a health-indicators.
