Approximately one-third of the global population uses complementary medicine, as yoga and meditation, not endorsed by evidence-based conventional medicine and, with more difficulties in case of pregnancy. Our study investigates the prevalence of Complementary and Alternative Medicine (CAM) usage in Novara (Italy) and its province through a survey to pregnant women at 36 gestational weeks. The sample consisted of 70 women, average age of 33 years, most Caucasian, highly educated, mostly employed, under private gynecological care, with a prevalence of CAM use of 24.3 % [95 % CI 14.83; 36.01]. Six women (35.3 %) did not inform their healthcare provider of using these medicines, 15 women (88.2 %) express willingness to use complementary medicine in their next pregnancy, while 2 (11.8 %) are uncertain. The study found a significant association between higher education and CAM usage among pregnant women. Other factors, including nationality, occupation, choice of private practice, parity, physical activity, diet, smoking, pregnancy complications, and vaccination status, did not show significant relationships with CAM usage. Our objective is to delineate the characteristics of CAM users, explore the methodologies and motivations of their usage, and ascertain any correlations with the rejection of conventional vaccination practices. The analyzed population consists of 70 women aged 32.9 years in mean, mostly Caucasian, with a high level of education. Most women are under private gynecological care (84.3 %), half of the participants are experiencing their first pregnancy. Physical activity levels vary, with 34.3 % reporting high activity levels. Regarding diet, 77.1 % consider their eating habits moderately healthy, with a notable portion of smokers women (24.3 %); 20.0 % have experienced pregnancy complications. 17 participants utilized non-conventional or alternative medicine, with a prevalence of 24.3 [95 % CI 14.83; 36.01]. Six women (35.3 %) did not inform their healthcare provider about using CAM. Seven women (46.7 %) claim significant beneficial effects in most cases, while 8 (53.3 %) state this occasionally. Based on their experiences, 15 women (88.2 %) express willingness to use complementary alternative medicine in their subsequent pregnancy, while 2 (11.8 %) are uncertain. Only one person (11.1 %) used this type of therapy as a substitute for conventional treatment, but they informed their attending physician. The study seeks to enhance our understanding of CAM utilization in pregnancy, informing more comprehensive and evidence-based healthcare practices for expectant mothers.
