Of these webpages, 181 (59.3{\%}) included information regarding weight gain during pregnancy. Out of 181 webpages, 62 (34.3{\%}) contained no specific recommendations, 48 (26.5{\%}) contained accurate but incomplete recommendations, 41 (22.7{\%}) contained complete and accurate recommendations, and 22 (12.2{\%}) were inaccurate. Webpages were most commonly from for-profit websites (112/181, 61.9{\%}), followed by government (19/181, 10.5{\%}), medical organizations or associations (13/181, 7.2{\%}), and news sites (12/181, 6.6{\%}). The largest proportion of for-profit sites contained no specific recommendations (44/112, 39.3{\%}). Among pages that provided inaccurate information (22/181, 12.2{\%}), 68{\%} (15/22) were from for-profit sites. Conclusions: For-profit websites dominate the online space with regard to weight gain during pregnancy and largely contain incomplete, inaccurate, or no specific recommendations. This represents a significant information gap regarding an important risk factor for obesity among mothers and infants. Our findings suggest that greater clinical and public health efforts to disseminate accurate information regarding healthy weight gain during pregnancy may help prevent significant morbidity and may support healthier pregnancies among at-risk women and children.
