Low Prepregnancy Ideal Weight:Height Ratio in Women with Hyperemesis Gravidarum
Authors:  Burton Rochelson, M.D., Nidhi Vohra, M.D., J. Darvishzadeh, B.A., and Michelle Pagano, R.N.C.
  OBJECTIVE: To determine if a low prepregnancy weight:height ratio is a risk factor for hyperemesis.

STUDY DESIGN: A retrospective chart review was conducted on 38 patients admitted to North Shore University Hospital for hyperemesis over a 5-year period. Prepregnancy weight, body mass index and percent ideal weight:height ratio in this group were compared to findings on 79 randomly selected control patients not admitted for hyperemesis.

RESULTS: There was a significantly higher incidence of prepregnancy underweight women (low percent ideal weight for height) in patients admitted for hyperemesis as compared to controls (P<.01). Thyroid-stimulating hormone was low in 19% of patients tested.

CONCLUSION: A low prepregnancy percent ideal weight:height ratio may predispose women to the development of hyperemesis. (J Reprod Med 2003;48:422- 424)
