#### 4.3.2 Sports Information Needs of Different Gender Users  
Analysis of the user attributes of the topics, we found that men are most concerned about sports events regarding the eight primary topics, accounting for 27.71%. Women are most concerned about sports shaping and weight loss, accounting for 21.42%, about twice the proportion of men. Both men and women ranked second regarding information needs about sports skills. Men ranked third in terms of information needs about professional athletes and teams, nearly three times the proportion of women. Regarding sports health information, women's needs are nearly twice as high as men's (Table 2). [PERSON] et al. [56] found that women tend to have more negative evaluations of body size and appearance than men, and the resulting pressure to lose weight makes women feel more strongly negative about their bodies. \begin{table}

Given the relatively wide range of information demanded by each primary topic, to further explore the similarities and differences of information required by different genders in online Q&A communities, the information requested by different genders for secondary topics was analyzed. Figure 5 shows the proportion of male and female information needs in each secondary topic. Thirty-seven out of forty topics have more male than female information needs. In the topics of NBA highlights and roasts and NBA regular-season highlights, the gender of information seekers is all male. The most significant gap between men and women is basketball and soccer sports. The number of questions on exercise, body part shaping, and yoga learning is higher for women than men. The number of female questions on yoga learning is more than 50% higher than that of male questions. Table 3 shows the proportion of male and female users in the secondary topic information needs categories and reveals more specific differences in sports information needs between men and women. The top 10 sports information needs topics are different. For male users, NBA player performance, European soccer league, and NBA team are the topics with the highest information needs. Sports slimming, sports protection and rehabilitation, and middle and long-distance running and marathon performance improvement are the most popular topics for women.
