Brief Summary

The aim of this study was to investigate the clinical efficacy of olive oil on the severity and progression of striae gravidarum. This randomized controlled clinical trial included 156 primipara women who were early third trimester. They were randomly allocated into two groups: an experimental group and a control group. Women in the experimental group applied olive oil to their abdomen twice a day in the morning and evening. The control group had no intervention.

Outcome Measures

Primary Outcomes (4)

  • Prevent the severity and progression of SG

    The participants completed the Maternal Information Forms through face-to-face interviews with an unbiased midwife who was working in the outpatient clinic on the day the data were collected.The women in the experimental group were asked to apply 10 cc (4 tablespoons) of extra virgin olive oil to the entire abdomen by hand without massaging twice a day in the morning and evening. The control group did not undergo any intervention. The women were called via telephone by the researcher once a week and asked whether they were performing the application. Women who were not applying the olive oil or who were using other medicines or creams (at least three days a week) were excluded from the study. The women in the control group were asked whether they were performing any applications. Those who were applying any products were also excluded. The striae was evaluated all groups at 37 weeks of gestation based on the Fitzpatrick Skin Type Scale and Davey's Severity Score by obstetrician.

    All the participating women were followed-up from the 28th week of gestation to the 37th week of gestation.

  • Maternal information form

    The Maternal Information Form was used to select whether pregnant women met the study.This form, which was developed by the researchers in line with knowledge of the literature, included 30 items questioning the participants' sociodemographic ch criteria.

    All the participating women were followed-up from the 28th week of gestation to the 37th week of gestation.

  • The Fitzpatrick Skin Type Scale

    The Fitzpatrick Skin Type Scale was developed by Fitzpatrick in 1975 to classify skin type.This scale uses genetic structure, eye color, reaction to sunlight to assign a skin type. According to the scale, the skin types vary from the extremely sensitive type, which always burns and does not tan, to the sun-resistant type, which is darkly pigmen and response to sunlight.

    All the participating women were followed-up from the 28th week of gestation to the 37th week of gestation.

  • Davey's Severity Score

    Davey's Severity Score is a scoring method developed by Davey in 1972 to measure the severity of SG.It divides the abdomen into four equal quadrants. Each quadrant is rated as "0" for clean skin, "1" for moderate striae, and "2" for multiple striae. Accordingly, the total score ranges from 0 to 8.

    All the participating women were followed-up from the 28th week of gestation to the 37th week of gestation.

Masking Details
This study was a randomized controlled clinical trial. To avoid bias, an impartial midwife who was working in the outpatient clinic on the day the data were collected and was not among the researchers asked each participant to select one of two closed envelopes that included the letters A (experimental group) or B (control group). The pregnant women were assigned to the experimental and control groups depending on the letter in the envelope they chose. Then, the researcher registered the participants in the experimental and control groups on a list. The obstetrician and pregnant women were informed about the procedure, but the obstetrician did not know which procedure would be applied to which pregnant woman. The pregnant women did not know why olive oil was being used. The participating women signed an informed consent form knowing that they could withdraw from the study at any time
