Plain English Summary
Background and study aims
Stretch marks affect many women during pregnancy, particularly in the third trimester. They affect between 50% and 90% of women and are most commonly found during a first pregnancy. They appear as red lines or streaks that fade slowly after the pregnancy to leave pale lines on the skin. Areas of the body frequently affected are the abdomen, breasts, thighs and buttocks. They are reported as affecting women’s perception of themselves. Further their prevention is important to women, and women frequently ask how they can be prevented during pregnancy. There is a lack of research on the prevention of stretch marks and there is a need for large studies to investigate how effective some of the products used by women are. The aim of this study is to examine the feasibility of undertaking a larger trial to evaluate the effects of a moisturising oil on the prevention and reduction of stretch marks in pregnancy, which has not being done to date.
Who can participate?
Women aged 18 and older who are around 12-16 weeks pregnant (with one baby).
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are asked to apply around 2 ml (about two pumps) of the plain moisturising oil daily to their abdomen after showering, from when they join the study until 38-41 weeks of pregnancy. Those in the second group are asked not to apply any treatment or skin product to their abdomen during pregnancy. Participants are asked to keep diaries of the application as appropriate. Participants receive two weekly text messages to remind them of their participation. Those in the first group are asked to bring their empty oil bottles to an interview at 38-41 weeks of pregnancy. Participants undergo health questions and are measured for weight at the start of the study and at the final assessment between 38-41 weeks of pregnancy.
What are the possible benefits and risks of participating?
There are no direct benefits or risks of participating.

| Scientific title | Prevention of striae gravidarum: a pilot trial |
| Study hypothesis | The aim of the study is to evaluate the feasibility of conducting a randomised controlled trial to evaluate the effectiveness of a moisturising oil (commercially available moisturising oil) compared to no treatment for the prevention and reduction in severity of striae gravidarum. |
| Ethics approval(s) | Galway Clinical Research Ethics Committee for University College Hospital Galway, 08/06/2017, ref: C.A.1770-Prevention of Striae Gravidarum: A Pilot Trial |
| Condition | Striae gravidarum |
| Intervention | Participants are randomly allocated to either the intervention or the control group using a 1:1 randomisation ratio using random block sizes. Intervention group: Participants receive a moisturising oil (commercially available moisturising oil). They are asked to apply approximately 2 ml per day (two pumps of oil) to their abdominal skin over 26 weeks of their pregnancy (i.e. between 12-14 weeks up to approximately 38 weeks gestation) (updated 16/07/2018: between 12-16 weeks up to approximately 38 weeks gestation) Control group: Participants do not receive any treatment. Participants are asked to keep diaries of the application as appropriate. Participants receive two weekly text messages to remind them of their participation. Those in the intervention group are asked to bring their empty oil bottles to an interview at 38-41 weeks of pregnancy. Participants are followed up at 38-41 weeks of gestation to see if the study is feasible and to assess their level of striae gravidarum. They undertake assessment interviews at this time and are measured for weight. |

| Primary outcome measure | 1. Number and proportion of women who are recruited, enrolled, complete the study and adhere to the intervention and control guidelines is measured using trial register form and outcomes assessment form, at enrolment (12-14 weeks gestation; updated 16/07/2018: 12-16 weeks gestation) and outcomes assessment interview (38-41 weeks gestation) 2. Percentage of potentially eligible women who are recruited/enrolled to the study is measured using trial register form at enrolment 3. Challenges with the randomisation process is reported based on the researcher’s notes at the enrolment/randomisation stage 4. Number and proportion of women who withdraw, drop out or deviate from the protocol guideline is measured using the outcome assessment form at 38-41 weeks gestation 5. Reasons for non-recruitment, non adherence, or attrition is measured using the Trial register form and Outcome assessment form at enrolment (12-14 weeks gestation; updated 16/07/2018: 12-16 weeks gestation) and outcomes assessment interview (38-41 weeks gestation) 6. Women's rating of the tolerability/acceptability and effectiveness of the intervention is measured using a rating scale at 38-41 weeks of pregnancy 7. Completeness of data collection for outcomes is measured using % of missing data at outcomes assessment (38-41 weeks gestation) 8. Challenges with data analysis is reported based on the researchers study notes at the analyses stage 9. Number and proportion of women developing striae gravidarum in the intervention and control group is measured using the Davey instrument (1972) at 38-41 weeks 10. Number and proportion of women developing mild, moderate or severe striae gravidarum is measured using Classification system of mild, moderate or severe at 38-41 weeks 11. Women's perception of the severity of striae gravidarum is measured using a grading system of none, mild, moderate or severe at 38-41 weeks |
| Secondary outcome measures | Infant's birth gestation and infant weight is measured using number of weeks at birth & Kg recorded in the mother’s notes at time of birth. |
