Navigating Pregnancy: Information Sources and Lifestyle Behavior Choices-A Narrative Review

Background: Accessible health information during pregnancy is important to positively affect maternal and fetal health. However, the quality and accuracy of health information can greatly vary across numerous sources. This narrative review is aimed at summarizing the literature on pregnant individuals' information sources and how these sources influence their habits toward GWG, PA, and nutrition. Such data will highlight preferences and needs, reveal challenges, and identify opportunities for improvement. Methods: We searched PubMed for studies published in the last decade. Out of 299 studies initially identified, 20 (16 quantitative and four qualitative) met the eligibility criteria (investigating information sources and their influence on health habits toward GWG, PA, nutrition, pregnant participants, adequate data reporting, and being available in full text). Results: Primary sources of health information varied. The Internet (26%-97%) and healthcare providers (HCPs) (14%-74%) predominated, followed by family/friends (12%71%), books/magazines (49%-65%), and guidelines/brochures (25%-53%). Despite the widespread use of the Internet, HCPs were considered the most reliable source. The use of the Internet to retrieve health information was reported to be 2-4 h a week, and < 50% discussed the online information with their HCP. The Internet was also used as a supplementary resource on topics raised by HCPs. Regarding the influence on health habits, the Internet, HCPs, media, and family positively influenced GWG and promoted adherence to recommended guidelines (OR = 0.55-15.5). Only one study showed a positive association between Internet use and PA level. The Internet, media, HCPs, and information brochures were associated with better adherence to nutritional recommendations. Conclusions: Pregnant individuals relied on the Internet and HCP, with a preference for the Internet despite trust in midwives. Several sources of health information were positively associated with adherence to GWG and nutrition recommendations. Improving the quality of online information should be a priority for policymakers and health authorities.
