The changes of body mass index and abdominal fatness in postpartum period / 대한산부인과학회지

OBJECTIVE: To investigate the changes of body mass index (BMI) and abdominal fatness of women in postpartum period, and to evaluate the relationship between two factors. METHODS: Sixty uncomplicated postpartum women were included. BMI and abdominal fatness using bioelectric impedance method were measured three times; at postpartum one day, one week, and six weeks. RESULTS: Mean BMI was 25.9+/-3.9 kg/m2, 24.8+/-3.8 kg/m2, 23.5+/-3.8 kg/m2, and abdominal fatness was 0.843+/-0.058, 0.850+/-0.054, 0.849+/-0.056 at postpartum one day, one week, and six weeks, respectively. The incidence of overweight women (BMI 23-24.9 kg/m2) was 35%, 25%, 20%, and the incidence of obesity women (BMI> or =25 kg/m2) was 45%, 38.3%, 26.7%, and the incidence of android obesity (abdominal fatness>0.85) was 43.3%, 43.3%, 38.3% at each three postpartum period. The cut-off values of BMI to predict android obesity was >24.9 kg/m2, >23.2 kg/m2, and >22.6 kg/m2 at postpartum one day, one week, and six weeks, respectively. CONCLUSION: The changes of postpartum body weight must be explored with abdominal fatness as well as BMI, and standard references for each postpartum periods are needed.

Dynamics of Body Mass Index and Abdominal Fatness in Postpartum Period / 대한산부인과학회지

OBJECTIVE: To investigate the dynamics of body mass index (BMI) and abdominal fatness of women in postpartum period, and to find cut-off values of BMI to predict android obesity. METHODS: Forty-three uncomplicated postpartum women were included. BMI and abdominal fatness using bioelectric impedance method were measured three times; at postpartum one day, one week, and six weeks. RESULTS: BMI was 24.9 +/- 2.6, 24.1 +/- 2.4, 23.0 +/- 2.4, and abdominal fatness was 0.842 +/- 0.035, 0.845 +/- 0.039, 0.839 +/- 0.036 at postpartum one day, one week, and six weeks, respectively. The incidence of overweight women (BMI 25-29.9) was 46.5%, 34.9%, 25.6%, and the incidence of android obesity (abdominal fatness>0.85) was 37.2%, 32.6%, 30.2% at each three postpartum period. The cut-off values of BMI to predict android obesity was >25.3, >23.6, and >22.9 at postpartum one day, one week, and six weeks, respectively. CONCLUSION: The dynamics of postpartum body weight must be explored with abdominal fatness as well as BMI. Further prospective long-term follow-up studies in a larger scale will be warranted to confirm these findings.
