Few animal experiments and volunteer-based intervention studies have showed a controversial effect of spicy foods on abdominal obesity. We aimed to examine the association between spicy food frequency, spicy flavor, and abdominal obesity among Chinese Han population in the Sichuan Basin which area eating spicy foods relatively often.
A cross-sectional analysis was conducted using the Sichuan Basin baseline data from the China Multi-Ethnic Cohort (CMEC) study, including data from electronic questionnaires, anthropometric measurements and blood sample collection. A total of 40,877 adults (22,503 females) aged 30-79 years were included in the final analysis. Multivariable logistic regression yielded adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for abdominal obesity associated with the strength of spicy flavor and frequency of spicy food intake.
The prevalence of daily spicy food eating was 47.3% in males and 52.7% in females, the percentages of abdominal obesity were 52.3%, 48.8%, 51.6% and 55.5% in the spicy food intake subgroups of never, 1-2 days/week, 3-5 days/week and 6-7 days/week, respectively. Compared with males who never consumed spicy food, the adjusted ORs (95% CIs) in the 1-2 days/week, 3-5 days/week and 6-7 days/week subgroups were 1.21 (1.09, 1.34), 1.35 (1.21, 1.51), and 1.35 (1.25, 1.47), respectively (P < 0.001). The corresponding odds ratios for females were 0.95 (0.87, 1.05), 1.14 (1.03, 1.26), and 1.25 (1.16, 1.35), respectively (P < 0.001). Similarly, compared with no spicy flavor, the adjusted ORs (95% CIs) of mild, middle, and strong spicy strength for abdominal obesity in males were 1.27 (1.17, 1.38), 1.51 (1.37, 1.67), and 1.36 (1.11, 1.67) respectively (P < 0.001). The corresponding odds ratios for females were 1.14 (1.06, 1.23), 1.27 (1.15, 1.40), and 1.32 (1.06, 1.65), respectively (P < 0.001).
The data indicated that spicy food consumption was a risk factor for abdominal obesity among Chinese adult population in the Sichuan Basin. The results need to be approved by large cohort studies.
很少有动物实验和基于志愿者的干预研究表明辛辣食物对腹部肥胖有争议的影响。我们旨在检验辛辣食物频率、辛辣味与四川盆地汉族人群腹部肥胖之间的关联，该地区经常食用辛辣食物。
使用中国多民族队列（CMEC）研究的四川盆地基线数据进行横断面分析，包括电子问卷、人体测量和血液样本采集。共纳入 40877 名 30-79 岁的成年人（女性 22503 名）进行最终分析。多变量逻辑回归得出与腹部肥胖相关的辛辣味强度和辛辣食物摄入频率的调整比值比（OR）和 95%置信区间（CI）。
男性每日食用辛辣食物的比例为 47.3%，女性为 52.7%，在每周食用辛辣食物 1-2 天、3-5 天、6-7 天的亚组中，腹部肥胖的比例分别为 52.3%、48.8%、51.6%和 55.5%。与从不食用辛辣食物的男性相比，每周食用辛辣食物 1-2 天、3-5 天和 6-7 天的调整后 OR（95%CI）分别为 1.21（1.09，1.34）、1.35（1.21，1.51）和 1.35（1.25，1.47）（均 P<0.001）。女性的相应比值比分别为 0.95（0.87，1.05）、1.14（1.03，1.26）和 1.25（1.16，1.35）（均 P<0.001）。同样，与无辛辣味相比，男性中温和、中等和强烈辛辣强度与腹部肥胖相关的调整 OR（95%CI）分别为 1.27（1.17，1.38）、1.51（1.37，1.67）和 1.36（1.11，1.67）（均 P<0.001）。女性的相应比值比分别为 1.14（1.06，1.23）、1.27（1.15，1.40）和 1.32（1.06，1.65）（均 P<0.001）。
数据表明，辛辣食物的摄入是四川盆地汉族成年人腹部肥胖的一个危险因素。这些结果需要大队列研究来证实。
