Furthermore only50% of the original

Furthermore only50% of the original sample completed and were eligible for inclusion in phase two.This is a limitation of using online adverts for recruitment; participants may be more likely to take part due to heightened anonymity. However, this may also reduce likelihood of follow up as there searcher does not meet face to face at any time with the participant. Attrition was however equal across variables; it was not explained by body image or breast feeding (e.g.mothers with poorer image or who artificially fed not wishing to complete a second questionnaire). Attritionisan on going issue in health research,with significant socio-economic disparities, and is reflected in sampling similar studies (McAndrewetal.,2012; BrownandLee,2014; Hense et al.,2013;BrandandJungmann,2014)
