While there is evidence of ethnic variation in the prevalence of gastro-oesophageal reflux disease (GERD) symptoms, few population-based studies examine GERD symptom prevalence amongst the growing Hispanic minority in the US as well as Asians in the West.
To examine the prevalence, awareness and care patterns for GERD across different ethnic groups.
A population-based, cross-sectional survey was fielded in English, Chinese and Spanish that assessed self-reported GERD prevalence, awareness and care patterns in four ethnic groups (Caucasian, African American, Asian, Hispanic).
A total of 1172 subjects were included for analysis: 34.6% experienced GERD symptoms at least monthly, 26.2% at least weekly and 8.2% at least daily. Statistically significant differences in raw prevalence rates between racial groups were found: 50% of Hispanics experienced heartburn at least monthly, compared with 37% of Caucasians, 31% of African Americans and 20% of Asians (P > 0.0001). Significant differences in knowledge and care-seeking patterns by ethnicity were also observed.
This study confirms the high prevalence of GERD symptoms in the US and introduces Hispanics as the ethnicity with the highest prevalence rate. Asians in the US have higher rates of symptoms than in the Far East. These data demonstrate a need for culturally appropriate education about GERD symptoms and treatment.
尽管有证据表明，胃食管反流病（GERD）症状在不同种族中存在流行差异，但很少有基于人群的研究调查美国日益增长的西班牙裔少数族裔以及西方亚洲人群中 GERD 症状的流行情况。
研究不同种族群体中 GERD 的患病率、知晓率和治疗模式。
采用基于人群的横断面调查，以英文、中文和西班牙文进行，评估了四个种族（白种人、非裔美国人、亚洲人和西班牙裔）中自我报告的 GERD 患病率、知晓率和治疗模式。
共纳入 1172 名受试者进行分析：34.6%的受试者每月至少出现一次 GERD 症状，26.2%的受试者每周至少出现一次，8.2%的受试者每天至少出现一次。在种族群体之间，GERD 的原始患病率存在显著差异：50%的西班牙裔人每月至少出现一次烧心，而白种人、非裔美国人和亚洲人的这一比例分别为 37%、31%和 20%（P > 0.0001）。不同种族之间在知识和寻求治疗的模式方面也存在显著差异。
本研究证实了 GERD 症状在美国的高患病率，并指出西班牙裔人群是患病率最高的种族。美国的亚洲人群的症状发生率高于远东地区。这些数据表明需要进行文化适宜的 GERD 症状和治疗教育。
