摘要目的探讨女性和青少年糖摄入量与唾液细菌（变形链球菌和乳酸杆菌）的关系，以及糖摄入量与体重指数（BMI）的关系。设计横断面研究。调查问卷中报告了习惯性饮食摄入量，并收集和培养了全唾液样本。背景是瑞典的斯德哥尔摩。对象414名母亲和他们的16岁的孩子（57%的女孩）。结果报告的总糖摄入量与母亲的LB显着相关（P = 0.001），但在女儿和儿子（P = 0.03的母子互动）。当排除乳糖，LB和MS的关联是显着的女儿（P = 0.032和0.005，分别）。在多元回归模型中，高BMI和从牛奶中摄入糖与母亲的MS计数独立相关（R2 = 0.053）。在女儿中，来自饮料、糖果/巧克力和水果的糖都与MS计数独立相关（R2 = 0.074），而在儿子中，只有母亲的MS计数相关（R2 = 0.084）。高BMI、低熟食摄入量和高糖果/巧克力摄入量均与母亲的LB独立相关（R2 = 0.076），而除女儿的糖果/巧克力外，儿童中未发现显著相关性。BMI与母亲和儿童的细菌计数显着相关，而报告的糖摄入量则无关。结论报告的糖摄入量与细菌之间的关联一般较弱。在母亲和女儿中，发现了一些重要的联系，但在儿子中没有。细菌计数，但没有报告糖摄入量，与BMI呈正相关。
Abstract Objective To study associations between reported sugar intake and salivary bacteria (mutans streptococci, MS and lactobacilli, LB), and sugar intake in relation to body mass index (BMI), in women and adolescents. Design Cross-sectional study. Habitual dietary intake was reported in a questionnaire and whole saliva samples were collected and cultivated. Setting Stockholm, Sweden. Subjects Four hundred and fourteen mothers and their 16-year-old children (57% girls). Results Reported total sugar intake was significantly associated with LB in mothers (P = 0.001), but not in daughters and sons (P = 0.03 for mother–son interaction). When excluding lactose, the associations with LB and MS were significant in daughters (P = 0.032 and 0.005, respectively). High BMI and sugar intake from milk were independently associated with MS counts in mothers in a multiple regression model (R2 = 0.053). In daughters, sugar from beverages, candies/chocolates and fruits were all independently associated with MS counts (R2 = 0.074), whereas in sons, only mothers’ MS counts were associated (R2 = 0.084). High BMI, low intake from cooked meals and high intake of candies/chocolates were all independently associated with LB in mothers (R2 = 0.076), while, except for candies/chocolates in daughters, no significant associations were found in children. BMI was significantly associated with bacteria counts in both mothers and children, whereas reported sugar intake was not. Conclusion The associations between reported sugar intake and bacteria were generally weak. In mothers and daughters, some significant associations were found, but not in sons. Bacteria counts, but not reported sugar intake, were positively associated with BMI.
