The frequency of spicy food intake has recently been associated with a reduced risk of mortality in the Chinese population. This study aimed to prospectively examine the association between chilli intake and the incidence of overweight/obesity in a Chinese adult population.
Adults aged 20-75 years in the China Health and Nutrition Survey were followed between 1991 and 2011. Dietary data were collected during home visits using a 3-day food record in 1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011. Cox regression was used in the analysis. Overweight/obesity was defined as body mass index ⩾25 kg m.
A total 12 970 adults were followed for a median of 9 years. During 126 884 person-years of follow-up, 3203 subjects developed overweight/obesity. The absolute incidence rate of overweight/obesity was 26.4, 22.3, 24.4 and 20.5 per 1000 person-years among those who consumed no chilli or 1-20, 20.1-50, ⩾50.1 g per day, respectively. Chilli consumption was therefore inversely associated with the incidence of overweight/obesity. After adjusting for age, gender, energy and fat intake, smoking, alcohol drinking and physical activity, those whose cumulative average chilli intake was 0, 1-20, 20.1-50 and ⩾50.1 g per day had a hazard ratio for overweight/obesity of 1.00, 0.81 (95% confidence interval=0.73-0.89), 0.77 (0.69-0.86) and 0.73 (0.63-0.84); P for trend <0.001, respectively. There was no interaction between chilli intake and gender, income, education and residence (urban/rural) in relation to the risk of overweight/obesity.
Chilli intake is inversely associated with the risk of becoming overweight/obese in Chinese adults.
近期研究发现，在中国人群中，食用辛辣食物的频率与降低的死亡风险相关。本研究旨在前瞻性地探讨中国成年人群中辣椒摄入量与超重/肥胖发生率之间的关联。
对中国健康与营养调查中年龄在20-75岁的成年人进行了1991年至2011年的随访。1991年、1993年、1997年、2000年、2004年、2006年、2009年和2011年通过家访采用3天食物记录法收集饮食数据。分析采用Cox回归。超重/肥胖定义为体重指数≥25kg/m²。
共对12970名成年人进行了中位时间为9年的随访。在126884人年的随访期间，3203名受试者出现超重/肥胖。每天食用辣椒量为0克、1-20克、20.1-50克、≥50.1克的人群中，超重/肥胖的绝对发病率分别为每1000人年26.4例、22.3例、24.4例和20.5例。因此，辣椒消费与超重/肥胖的发生率呈负相关。在调整年龄、性别、能量和脂肪摄入量、吸烟、饮酒和身体活动后，每天累计平均辣椒摄入量为0克、1-20克、20.1-50克和≥50.1克的人群超重/肥胖的风险比分别为1.00、0.81（95%置信区间=0.73-0.89）、0.77（0.69-0.86）和0.73（0.63-0.84）；趋势P<0.001。在超重/肥胖风险方面，辣椒摄入量与性别、收入、教育程度和居住地（城市/农村）之间没有相互作用。
在中国成年人中，辣椒摄入量与超重/肥胖风险呈负相关。
