Introduction
Introduction Hawai`i

  • Obesity in the U.S. has become an epidemic

  • Obesity rates have increased by nearly 60% since 1991, and by 6% between 1998 and 1999 (CDC)

  • 50% of women 25-55 yrs of age are either overweight or obese


Introduction cont
Introduction (cont) Hawai`i

  • Adequate weight gain during pregnancy is important for optimal pregnancy outcomes

  • Excessive weight gain during pregnancy and retention of weight 6 months after delivery are predictors of long-term obesity


Introduction cont1
Introduction (cont) Hawai`i

  • Weight gain during pregnancy and weight retention postpartum vary by:

    • Prepregnancy BMI

    • Parity, Age

    • Breastfeeding, Smoking, Exercise

    • Race/ethnicity


Purpose of the study
Purpose of the study Hawai`i

  • Reported racial differences are between Black and White women

Methods
Methods Hawai`i

  • Cross sectional study of postpartum women attending the Hawai`i WIC Program in 1997-98

  • Weight gain during pregnancy self reported

  • Weight and height at postpartum visit measured by WIC staff

Conclusions
Conclusions WIC 1997-98

  • 30% of women were overweight or obese before pregnancy

  • Overweight and obese women had an excessive weight gain during pregnancy

  • Average weight retention at 5-6 months pp was 9.4 lbs, and 7.4 lbs after 8 months pp


Conclusions cont
Conclusions (cont) WIC 1997-98

  • Overall significant ethnic differences in prepregnancy BMI

  • Samoan had the highest mean prepregnancy BMI (29.7)

  • Filipino had the lowest mean prepregnancy BMI (22.5)


Conclusions cont1
Conclusions (cont) WIC 1997-98

  • Overall significant ethnic differences in weight gain during pregnancy

  • Samoans had the highest mean weight gain (37.3 lbs)

  • Asian had the lowest mean weight gain (29.1 lbs)


Conclusions cont2
Conclusions (cont) WIC 1997-98

  • Overall significant ethnic differences in weight retention

  • Samoan had the largest average wt retention (17.5 lbs)

  • Asian had the smallest average wt retention (9.6 lbs)


Conclusions cont3
Conclusions (cont) WIC 1997-98

  • Adjusting for weight gain during pregnancy, pp duration, and age, all ethnicities, except Black and Hawaiian, retained significantly more weight than Caucasian.

  • Samoan retained the most (3.5 lbs)

  • Asian retained the least (1.1 lbs)
