This same theme emerged as a perceived barrier to physical exercise in a study conducted by Weir, et al. (2010). In this study, 14 different pregnant women participated in semi-structured interviews. This qualitative study provided results consistent with women perceiving inconsistency of quality and relevant information about the potential benefits and hazards of physical activity during pregnancy. Insufficient advice and support systems conflicted whether the women in the study determined it would be beneficial to engage in the physical activity until their post-partum condition. Yet another study conducted by Evenson, et al. (2009) identified this same theme. inconsistency of information stemming from various sources. In this study, recruiting 1,535 pregnant women to engage in a survey, it was found that conflicting advice from health professionals and social reference figures complicated whether physical activity was beneficial or a potential detriment during pregnancy. One participant was described as identifying that her mother advised some degree of physical activity whilst her physician warned against conducting high degrees of physical movement (Evenson, et al.). Interpersonally, this same participant in the study faced chastisement from her husband related to physical activity and suggested that this participant spend more time lying down to ensure the baby was not injured (Evenson, et al.). Clarke and Gross (2004) conducted a study which recruited 57 pregnant women to participate in semi-structured interviews. This study found that whilst 96 percent of the sample had received information and advice about physical activity, from books, magazines, family and social acquaintances, lack of health information consistency served as a barrier to engaging in regular physical activity during their pregnancies (Clark and Gross). This might tend to suggest that pregnant women should turn away from pieces of advice stemming from non-professional individuals in their social environment.
