摘要:
目的 分析深圳市中小学生对含糖饮料的认知现状及其影响因素,为加强中小学生营养健康教育提供科学依据。 方法 按照深圳市行政区属划分,在各区属采用随机数字表法和方便抽样法,从深圳市中小学生中抽取40 135名6~18岁学生作为研究对象,收集其基本信息,调查其对含糖饮料的认知及相关影响因素等。 结果 中小学生含糖饮料认知得分 < 60,60~79,80~100分分别占5.6%,41.9%和52.4%。多因素线性回归分析结果显示,年级(四至六、初中、高中)、性别(女生)、父亲文化水平(高中或中专、大专、本科、硕士及以上)、母亲文化水平(高中或中专、大专、本科、硕士及以上)、关注配料表(偶尔、无)、家长劝阻或奖励行为(仅强制劝阻、几乎不劝阻,偶尔奖励、无奖励)、家中储备饮料情况(偶尔、无)与学生含糖饮料总认知得分均有相关关系(β值分别为-0.79,-1.19,-1.74,0.58,1.20,1.81,2.98,3.13,2.70,4.85,6.34,6.41,-0.99,-0.78,-1.81,-2.40,5.85,6.26,0.61,1.92,P值均 < 0.05)。年级(四至六、初中、高中)、性别(女)、父亲文化水平(大专、本科、硕士及以上)、母亲文化水平(高中或中专、大专、本科、硕士及以上)、家长劝阻行为(几乎不劝阻)、家长奖励行为(偶尔、无)、家中储备饮料情况(偶尔、无)与学生含乳饮料认知得分均相关(β值分别为-0.68,-0.92,-0.49,0.26,0.51,1.05,1.09,0.90,1.93,2.62,2.55,-0.68,0.93,1.13,0.21,0.92,P值均 < 0.05)。 结论 深圳市中小学生对含糖饮料的整体认知水平中等或较好。应针对性地加强学生及家长关于含糖饮料相关知识的宣教,同时减少家庭含糖饮料的可得性。 Abstract:Objective To explore the status of sugar-sweetened beverages(SSBs) and its associated factors among primary and middle school students in Shenzhen, providing reference for nutrition and health education. Methods A random number table and convenience sampling method was used to select 40 135 primary and middle school students aged 6-18 years in Shenzhen. Data was collected to investigate their SSBs knowledge and associated factors. Results The proportion of SSBs knowledge score less than 60 points, between 60-79 points and 80-100 points were 5.6%, 41.9% and 52.4%. Multivariate analysis showed that age(4-6 grade, junior middle and high school), gender(female), parents education(high school or vocational schools, colleges and universities as bachelors, masters or doctors), students pay attention to the ingredient list (seldom, none), parental dissuasion or reward behavior (only forced dissuasion, giving no dissuasion, occasional reward, no reward), and the storing beverages at home (seldom, none) were associated with total SSBs knowledge score and milk-containing beverage knowledge score (β=-0.79, -1.19, -1.74, 0.58, 1.20, 1.81, 2.98, 3.13, 2.70, 4.85, 6.34, 6.41, -0.99, -0.78, -1.81, -2.40, 5.85, 6.26, 0.61, 1.92, P < 0.05). Age(4-6 grade, junior middle and high school), gender(female), father's education background(with colleges and universities as bachelor, masters or doctors), mother's education background(high schools or vocational schools, colleges and universities as bachelors, masters or doctors), parents dissuation behaviors(giving no dissuation), parents' rewarding behavior(seldom, none), storing beverages at home(seldom, none) were associated with the total SSBs knowledge score and milk-containing beverage knowledge score(β=-0.68, -0.92, -0.49, 0.26, 0.51, 1.05, 1.09, 0.90, 1.93, 2.62, 2.55, -0.68, 0.93, 1.13, 0.21, 0.92, P < 0.05). Conclusion Primary and middle school students have moderate to high level of SSBs knowledge. It is necessary for students and their parents to learn more SSBs related nutrition healthy knowledge, and to reduce home availability of SSBs. -
