摘要:
目的 探讨广西壮族自治区中小学生龋齿与超重肥胖共患状况及其相关因素, 为制定针对性的预防策略提供科学依据。 方法 采用分层整群随机抽样法, 于2023年9—11月在广西调查178 700名小学四年级至高中三年级学生, 包括体格检查、口腔筛查及问卷调查。运用χ2检验和二元Logistic回归分析, 探究中小学生龋齿与超重肥胖共患的相关因素。 结果 广西中小学生龋齿及超重肥胖共患率为9.55%, 城区(9.95%)高于郊县(9.24%), 男生(10.54%)高于女生(8.54%), 小学生(11.49%)高于高中生(8.92%)及初中生(8.05%), 不住校学生(11.44%)高于住校学生(7.94%), 差异均有统计学意义(χ2值分别为26.07, 207.91, 471.54, 629.14, P值均<0.01)。多因素Logistic回归分析结果显示, 吃谷薯类早餐(OR=0.91, 95%CI=0.88~0.94)、过去1周喝过奶(OR=0.89, 95%CI=0.83~0.95)、睡眠达标(OR=0.95, 95%CI=0.91~0.99)、早和(或)晚刷牙(OR=0.82, 95%CI=0.73~0.93)的学生龋齿及超重肥胖共患的风险更低; 过去1周喝过饮料(OR=1.14, 95%CI=1.09~1.20)、过去1周吃过油炸食品(OR=1.11, 95%CI=1.06~1.17)、每天吃≥1次水果(OR=1.06, 95%CI=1.02~1.11)、每天吃≥1种水果(OR=1.07, 95%CI=1.01~1.12)、吃鱼禽肉蛋类早餐(OR=1.03, 95%CI=1.05~1.13)的学生龋齿及超重肥胖共患风险更高(P值均<0.05)。 结论 广西中小学生的饮食习惯和生活方式与龋齿及超重肥胖的共患相关。引导学生形成健康的生活习惯, 有助于预防龋齿及超重肥胖的发生。 Abstract:Objective To explore the comorbidity and associated factors of dental caries and overweight/obesity among primary and secondary school students in Guangxi, so as to provide a scientific basis for the development of targeted prevention strategies. Methods A stratified cluster random sampling method was used to survey 178 700 students from the fourth grade of primary school to the third year of high school in Guangxi Zhuang Autonomous Region from September to November 2023, including physical examination, oral screening, and questionnaire survey. Chi-square tests and binary Logistic regression analysis were employed to investigate the related factors of the co-occurrence of dental caries and overweight/obesity among students. Results The comorbidity rate of dental caries and overweight/obesity was 9.55%, with urban areas (9.95%) higher than rural counties (9.24%), boys (10.54%) higher than girls (8.54%), primary school students (11.49%) higher than senior high school students (8.92%) and junior high school students (8.05%), and non-boarding students (11.44%) higher than boarding students (7.94%), and all differences were statistically significant (χ2=26.07, 207.91, 471.54, 629.14, P<0.01). Multivariate Logistic regression analysis showed that consuming cereal for breakfast (OR=0.91, 95%CI=0.88-0.94), drinking milk in the past week (OR=0.89, 95%CI=0.83-0.95), meeting sleep standards (OR=0.95, 95%CI=0.91-0.99), and brushing teeth at least once a day (OR=0.82, 95%CI=0.73-0.93) had a lower risk of the comorbidity of dental caries and overweight/obesity. In contrast, drinking beverages in the past week (OR=1.14, 95%CI=1.09-1.20), consuming fried foods in the past week (OR=1.11, 95%CI=1.06-1.17), eating fruit ≥1 time every day (OR=1.06, 95%CI=1.02-1.11), consuming fruit ≥1 type every day (OR=1.07, 95%CI=1.01-1.12), and having fish, poultry, meat, or egg-based breakfasts (OR=1.03, 95%CI=1.05-1.13) had a higher risk of the comorbidity of dental caries and overweight/obesity (P<0.05). Conclusions Dietary habits and lifestyle behaviors are associated with the comorbidity of dental caries and overweight/obesity among primary and secondary school students in Guangxi. Guiding students to form healthy living habits is helpful to preven dental caries and overweight/obesity. -
