To broaden the currently limited reach of genomic innovations, research is needed to understand how psychosocial and cultural factors influence reactions to genetic testing in diverse subgroups. Cancer fatalism is important in cancer prevention and deserves theoretical and empirical attention in the context of genomics and behavior change.
The current study employed data from a randomized controlled trial (N = 593) offering skin cancer genetic testing (using the melanocortin-1 receptor [MC1R] gene) in primary care in Albuquerque, New Mexico, USA. We examined interrelations of cancer fatalism with demographics, general health beliefs, perceived risk, perceived control, sun protection and skin screening behaviors and cancer worry in the skin cancer context stratified across Hispanic versus non-Hispanic ethnicity, and examined cancer fatalism as a moderator of intervention effects on study primary outcomes, including 3-month sun protection, cancer worry and perceived risk.
Cancer fatalism was significantly related to the perception of control over skin cancer risk behaviors (ps ≤ 0.01) and demographics (ethnicity, education, health literacy; ps < 0.05), but not consistently related to general health beliefs or risk perception. Cancer fatalism did not moderate intervention effects on primary outcomes, except those with higher cancer fatalism randomized to intervention had higher levels of 3-month cancer worry (p = 0.019).
These findings will guide future work considering the role of cancer fatalism in use of genomic technologies in the general population. This work anticipates strategies required to address cancer fatalism as translational genomics becomes more commonly available to diverse general population subgroups.
为了扩大基因组创新目前有限的应用范围,需要研究了解社会心理和文化因素如何影响不同亚组人群对基因检测的反应。癌症宿命论在癌症预防中很重要,在基因组学和行为改变的背景下,它值得理论和实证关注。
本研究采用了来自美国新墨西哥州阿尔伯克基初级保健中提供皮肤癌基因检测(使用黑素皮质素 1 受体[MC1R]基因)的随机对照试验(N=593)的数据。我们在皮肤癌背景下,按西班牙裔与非西班牙裔族群分层,研究了癌症宿命论与人口统计学、一般健康信念、感知风险、感知控制、防晒和皮肤筛查行为以及癌症担忧之间的相互关系,还检验了癌症宿命论是否作为干预对研究主要结局(包括 3 个月的防晒、癌症担忧和感知风险)的影响的调节因素。
癌症宿命论与对皮肤癌风险行为的控制感(p≤0.01)和人口统计学因素(种族、教育、健康素养;p<0.05)显著相关,但与一般健康信念或风险感知不一致。癌症宿命论并没有调节干预对主要结局的影响,除了那些宿命论较高而被随机分配到干预组的人在 3 个月时有更高水平的癌症担忧(p=0.019)。
这些发现将指导未来的工作,考虑癌症宿命论在一般人群中使用基因组技术的作用。这项工作预计需要采取策略来解决癌症宿命论问题,因为转化基因组学越来越普遍地应用于不同的一般人群亚组。
