To answer this question, a laboratory study using pressure-induced pain was conducted to examine the pain threshold and pain tolerance levels of 178 Hong Kong Chinese adults (89 men and 89 women) between the ages of 18-45 years. The results of the study suggest that women had a significantly lower threshold and tolerance for pain than men and anxiety is an important factor in determining pain report in men. These findings are consistent with those obtained in overseas studies. What then is the significance of these findings for men and women in Hong Kong with regard to their pain experience? In Hong Kong culture, it is generally believed that women can tolerate more pain than men. It is however important to realize that this does not mean that women feel less pain than men. Despite their greater pain burden, women have learned to handle pain better than men do. Women use more coping strategies to deal with pain possibly because of their frequent encounter with pain in menstruation, and in labour and childbirth. The fact that Hong Kong women are living longer these days means that they are likely to suffer from chronic pain conditions. Greater awareness of gender differences in pain perception will ensure women will not be disadvantaged in painmanagement. Also, since anxiety may affect the sensory perception of pain in men, it is important that men learn how to cope with pain more effectively. Research interest in pain and gender is only beginning to emerge in Hong Kong society and public interest on this topic is increasing. More attention to gender issues should help ease pain for the individual person, male or female. 痛楚感觉男女大不同 Are There Gender Differences in Pain Perception? ■ 中大建筑系教授获规划署九百万元 研究香港风环境 CUHK Architecture Professor Awarded HK$ 9 Million by Planning Department to Study Hong Kong’s Wind Environment ■ 诺贝尔奖得奖人讲座反应热烈 本港与内地学界现场直播 Nobel Laureate Lecture Broadcast Live to Local Schools and Mainland Universities ■ 中大划艇队六连冠 CUHK Rowing Team Champion for the Sixth Year in a Row ■ 中大人同赏万众童心筹款音乐会 CUHK-Children’s Choir Fundraising Concert Features Music for a Good Cause ■ 中国工程院农业学部代表团来访 其他消息 Other News Items 以下消息详情,请上网 http://www.cuhk.edu.hk/iso/newslter/ 阅 览: Details of the following news items are available at http://www.cuhk.edu . hk/iso/newslter/: Chinese Academy of Engineering Delegates Visit CUHK ■ 中大工程学生崭新科技发明于Intel Cup比赛全国夺冠 ■ 商界领袖参与「星级学长计划」 致力培育中大MBA学生 Business Leaders Nurture MBA Students Through Elite Mentorship Programme ■ 政治学权威学者Larry Diamond于 香港中文大学谈全球民主化之障碍 Authority in Comparative Politics Larry Diamond Lectures at The Chinese University ■ 医院、大学和社区共创健康生活 Setting up of Patients’ Corner Through a Hospital-University- Community Partnership ■ 13 Research Projects Receive Funding Support 以下项目详情,请上网 http://www.cuhk.edu.hk/iso/ newslter/issue/284/discoveries.htm 阅览: ■ 青少年参加跳舞派对的风险行为研究 「 • Prof. Lee Chi Kin John, dean of Faculty of Education, has been re-appointed by the Secretary for Education and Manpower as a member of the Hong Kong Council for Academic Accreditation for one year from 1st October 2006. • Prof. Helen Meng, professor in the Department of Systems Engineering and Engineering Management, has been re-appointed by the Secretary for Commerce, Industry and Technology as a member of the Digital 21 Strategy Advisory Committee for two years from 1st October 2006. • Prof. Yeung Chung Kwong, professor of surgery, has been appointed by the Medical Council of Hong Kong to the panel of assessors for the purpose of conducting disciplinary inquiry for one year from 5th September 2006. • Prof. Wing Yun Kwok, professor in the Department of Psychiatry, has been appointed by the Medical Council of Hong Kong to the panel of assessors for the purpose of conducting disciplinary inquiry for one year from 5th September 2006. • Prof. So Kee Long Billy, associate pro-vice-chancellor, has been appointed as a member of the Council of The Open University of Hong Kong for three years from 1st October 2006. • Prof. Low Chee Keong, associate professor in the School of Accountancy, has been appointed as a member of the Listing Committee of the Stock Exchange of Hong Kong Limited for one year from May 2006. • Prof. Lau Tak Fai Joseph, director of Centre for Epidemiology and Biostatistics, has been appointed as a member of the Children and Youth Service Development Sub-committee of the Friends of Scouting 2006/2007.
