Nutrition literacy plays an important role in children's dietary habits and nutrition. This study aimed to analyse the status of nutrition literacy and its influencing factors amongst middle school students in Chongqing, China. "Nutrition literacy scale for middle school students in Chongqing" was used in 29 districts of Chongqing in September 2020. The scores of nutrition literacy and its' three sub-domains (functional, interactive and critical nutrition literacy) were divided into low and high groups based on their median scores. Binary logistic regression was used to measure the influencing factors of nutrition literacy. A total of 18,660 middle school students were included in this study. The median of nutrition literacy of middle school students was 61.68 (IQR = 14.37). Interactive nutrition literacy had the highest score (median = 70.00, IQR = 20.00), followed by functional nutrition literacy (median = 68.69, IQR = 14.14) and critical nutrition literacy (median = 45.83, IQR = 25.00). Students who were the minority (OR = 0.71, 95% CI = 0.637-0.785), in senior high school (OR = 0.51, 95% CI = 0.477-0.548), in rural areas (OR = 0.85, 95% CI = 0.790-0.911), receiving school meal support from the government (OR = 0.63, 95% CI = 0.591-0.664), with other caregivers' parenting (OR = 0.86, 95% CI = 0.805-0.914), with parents having a low level of education and with an abnormal BMI [thin (OR = 0.91, 95% CI = 0.837-0.990), overweight (OR = 0.87, 95% CI = 0.785-0.968), and obese (OR = 0.83, 95% CI = 0.767-0.902)] presented less probability of being a high level of nutrition literacy. Our results could assist public health authorities in developing strategies of nutrition literacy promotion for references and theoretical foundations.
营养素养在儿童的饮食习惯和营养中起着重要作用。本研究旨在分析中国重庆市中学生营养素养的现状及其影响因素。2020 年 9 月，在重庆市 29 个区使用“重庆市中学生营养素养量表”。根据中位数将营养素养及其三个子领域（功能性、互动性和批判性营养素养）的得分分为低分组和高分组。采用二项逻辑回归分析营养素养的影响因素。共纳入 18660 名中学生。中学生营养素养中位数为 61.68（IQR=14.37）。互动性营养素养得分最高（中位数=70.00，IQR=20.00），其次是功能性营养素养（中位数=68.69，IQR=14.14）和批判性营养素养（中位数=45.83，IQR=25.00）。少数民族（OR=0.71，95%CI=0.637-0.785）、高中生（OR=0.51，95%CI=0.477-0.548）、农村地区（OR=0.85，95%CI=0.790-0.911）、接受政府提供的学校膳食支持（OR=0.63，95%CI=0.591-0.664）、其他照顾者育儿（OR=0.86，95%CI=0.805-0.914）、父母受教育程度低以及 BMI 异常[消瘦（OR=0.91，95%CI=0.837-0.990）、超重（OR=0.87，95%CI=0.785-0.968）和肥胖（OR=0.83，95%CI=0.767-0.902）]的学生营养素养高水平的可能性较小。我们的研究结果可以为公共卫生当局提供制定营养素养促进策略的参考和理论基础。
