To assess the public reach, awareness, understanding and response to the burn time and the Ultra Violet Index (UVI) in media weather reports in New Zealand.
Data from a representative sample (n = 396), ages 16-44 years, were gathered over four consecutive summer weeks of 1999 via a random digit dialling telephone survey. Items collected included sources of weather reports and their frequency of use; knowledge, understanding, perception and use of the burn time and the UVI; sun-related beliefs, attitudes and behaviours.
Exposure to weekend weather bulletins was sustained, and occurred mainly via television (83%) and radio (50%). There was greater awareness of the burn time than the more recent UVI (89% vs 43%). The UVI was less often used to guide sun protection actions (49% vs 63%) but better understood (94% vs 66%) and more often recalled along with sun protective messages (56% vs 32%) than the burn time. Few could describe the burn time or the UVI for the past Sunday. Self-perceived understanding of the burn time was higher than its measured, sub-optimal, comprehension (96% vs 65%).
Further efforts are needed to promote the UVI, particularly on TV1 and on radio, and to reach younger adults and less educated groups. For a transition period, presentation of the burn time should be restricted to complementing the UVI. Thereafter, the UVI should become the standard indicator of UV level in New Zealand.
评估新西兰媒体天气报道中公众对晒伤时间和紫外线指数(UVI)的接触、认知、理解及反应。
1999年连续四个夏季周,通过随机数字拨号电话调查收集了来自16 - 44岁有代表性样本(n = 396)的数据。收集的项目包括天气报道的来源及其使用频率;对晒伤时间和紫外线指数的知识、理解、认知及使用;与太阳相关的信念、态度和行为。
对周末天气公告的接触持续存在,主要通过电视(83%)和广播(50%)。与更新的紫外线指数相比,对晒伤时间的认知度更高(89%对43%)。紫外线指数较少被用于指导防晒行动(49%对63%),但比晒伤时间更容易理解(94%对66%),并且与防晒信息一起被更多地回忆起来(56%对32%)。很少有人能描述过去周日的晒伤时间或紫外线指数。自我感知的对晒伤时间的理解高于其实际测量的、不理想的理解程度(96%对65%)。
需要进一步努力推广紫外线指数,特别是在电视一台和广播上,并覆盖年轻成年人和受教育程度较低的群体。在过渡时期,晒伤时间的呈现应限于补充紫外线指数。此后,紫外线指数应成为新西兰紫外线水平的标准指标。
