The evidence base for the health effects of spice consumption is insufficient, with only one large population-based study and no reports from Europe or North America. Our objective was to analyze the association between consumption of hot red chili peppers and mortality, using a population-based prospective cohort from the National Health and Nutritional Examination Survey (NHANES) III, a representative sample of US noninstitutionalized adults, in which participants were surveyed from 1988 to 1994. The frequency of hot red chili pepper consumption was measured in 16,179 participants at least 18 years of age. Total and cause-specific mortality were the main outcome measures. During 273,877 person-years of follow-up (median 18.9 years), a total of 4,946 deaths were observed. Total mortality for participants who consumed hot red chili peppers was 21.6% compared to 33.6% for those who did not (absolute risk reduction of 12%; relative risk of 0.64). Adjusted for demographic, lifestyle, and clinical characteristics, the hazard ratio was 0.87 (P = 0.01; 95% Confidence Interval 0.77, 0.97). Consumption of hot red chili peppers was associated with a 13% reduction in the instantaneous hazard of death. Similar, but statistically nonsignificant trends were seen for deaths from vascular disease, but not from other causes. In this large population-based prospective study, the consumption of hot red chili pepper was associated with reduced mortality. Hot red chili peppers may be a beneficial component of the diet.
关于食用香料对健康影响的证据基础并不充分,仅有一项基于大规模人群的研究,且没有来自欧洲或北美的报告。我们的目标是利用来自美国国家健康与营养检查调查(NHANES)III的基于人群的前瞻性队列,分析食用红辣椒与死亡率之间的关联。NHANES III是美国非机构化成年人的代表性样本,参与者于1988年至1994年接受调查。对16179名至少18岁的参与者测量了食用红辣椒的频率。全因死亡率和特定病因死亡率是主要的结局指标。在273877人年的随访期间(中位随访时间为18.9年),共观察到4946例死亡。食用红辣椒的参与者的总死亡率为21.6%,而未食用者为33.6%(绝对风险降低12%;相对风险为0.64)。在对人口统计学、生活方式和临床特征进行调整后,风险比为0.87(P = 0.01;95%置信区间为0.77, 0.97)。食用红辣椒与死亡瞬间风险降低13%相关。对于血管疾病导致的死亡也观察到了类似但无统计学意义的趋势,而其他原因导致的死亡则未观察到这种趋势。在这项基于大规模人群的前瞻性研究中,食用红辣椒与死亡率降低相关。红辣椒可能是饮食中的有益成分。
