Prevention of striae gravidarum with cocoa butter cream

To determine whether cocoa butter cream is effective in preventing striae gravidarum.

This randomized, double-blind, placebo-controlled trial enrolled 300 pregnant women: 150 women received cocoa butter cream and 150 women received a placebo cream. The women were followed-up from 16 weeks of pregnancy to delivery to assess the development of striae gravidarum. Maternal height, weight, and abdominal girth were recorded at each visit. After delivery the placenta was weighed, and anthropometry and Apgar scores of the neonate were recorded.

The 2 groups had similar clinical parameters at booking. Striae gravidarum developed in 44% of patients using cocoa butter cream compared with 55% of those using placebo; the difference was not significant (chi(2)=2.8, df(1), P=0.09). Striae gravidarum were more common among younger women and those with large neonates. However, no relationship was found between development of striae and body mass index.

Cocoa butter cream does not prevent striae gravidarum. In Afro-Caribbean women, development of striae is related to young age of the mother and large neonates.
