三个地方问一下，谢谢

Race and ethnicity are two other demographic factors that have been well studied in the fields of pain and epidemiology. Over the past several decades, an expanding body of research has identified dissimilitude in health across different ethnicities and has highlighted the incongruity of the prevalence, treatment, progression, and outcomes of pain- related conditions in various ethnicities. However, it is important for one to consider the weaknesses of such data due to cultural perspectives that may strongly influence reporting of pain as well as disparities in quality and access to care. According to the CDC report, the highest rate of both low back and neck pain were experienced in the cultural categories of American Indian or Alaskan Native. People identifying as White were second in both categories [12]. According to the National Health Interview Survey in 2009, Asian adults were less likely to have lower back pain than White, Black, American Indian, or Alaskan Native adults [23]. The research regarding the etiology of interethnic differences in pain is ongoing; however some factors such as disparities in treatment, sociocultural differences, and genetic variability have been proposed.

种族和族裔是另外两个在疼痛和流行病学领域得到深入研究的人口统计学因素。在过去几十年里，越来越多的研究发现了不同种族间的健康差异，并强调了不同种族疼痛相关疾病的患病率、治疗、进展和预后的不一致性。然而，重要的是要考虑到这些数据的不足，因为文化可能会强烈影响疼痛的报告以及在疼痛程度和治疗的差异。根据CDC报告，在美洲印第安人或阿拉斯加原住民的腰痛和颈部疼痛的发生率最高，白人排腰痛和颈部疼痛的第二位^[12]。根据2009年的美国国家健康访谈调查，亚洲成年人比白人、黑人、美洲印第安人或阿拉斯加原住民成年人出现腰痛的可能性更小^[23]。目前正在进行关于种族间疼痛差异病因的研究，同时也提出了如治疗上、社会文化、以及遗传变异性等因素的差异。

1.in the cultural categories of American Indian or Alaskan Native.在美洲印第安人或阿拉斯加原住民的文化类别中，文化类别需要翻译吗？

2.People identifying as White were second in both categories，both categories 是指腰痛和颈部疼痛吗？

3.however ，为啥这里有个转折，这里顺承下来比较好
