In this cross-sectional study, carried out in 2012, we assessed factors associated with tooth loss among adolescents from Minas Gerais, Brazil, utilizing data from a secondary database. Individual and local-level variables were selected to represent health determinants. Individual covariates included sex, age, skin color, maternal education, household income, use of dental services, and self-perceived need for dental care. The contextual variables included illiteracy, unemployment, income, primary health care coverage, dental specialty centers, and oral health team coverage. Multilevel logistic regression models were used to examine the relationship between contextual and individual variables and the outcome (STATA version 16.0) - odds ratio (OR) and 95% confidence interval (CI). The prevalence of tooth loss was 12.4%. Female individuals were 40% more likely to experience the outcome (OR: 1.40; 95%CI: 1.01-1.98). Increased age was associated with greater tooth loss (OR: 1.16; 95%CI: 1.03-1.31). Low maternal education (OR: 1.72; 95%CI: 1.13-2.61), low household income (OR: 1.71; 95% CI 1.09-2.67), and self-perceived dental needs (OR: 2.94; 95% CI 1.97-4.39) were also associated with the outcome. Regular dental visits reduced the likelihood of tooth loss by 38% (OR: 0.62; 95 CI 0.44-0.87). Larger tooth loss was observed in municipalities with higher illiteracy rates (OR: 1.04; 95%CI: 1.01-1.08). Municipalities with larger dental specialty centers were associated with the outcome (OR: 0.58; 95%CI: 0.37-0.92). Contextual and individual factors influenced tooth loss in adolescents from Minas Gerais, Brazil, but socioeconomic status was the main determinant.
在这项于2012年开展的横断面研究中，我们利用一个二级数据库中的数据，评估了巴西米纳斯吉拉斯州青少年牙齿脱落的相关因素。选取了个体层面和地区层面的变量来代表健康决定因素。个体协变量包括性别、年龄、肤色、母亲教育程度、家庭收入、牙科服务使用情况以及自我感知的牙齿护理需求。背景变量包括文盲率、失业率、收入、初级卫生保健覆盖率、牙科专科中心以及口腔健康团队覆盖率。使用多水平逻辑回归模型来检验背景变量和个体变量与结果之间的关系（STATA 16.0版本）——比值比（OR）和95%置信区间（CI）。牙齿脱落的患病率为12.4%。女性个体出现该结果的可能性高40%（OR：1.40；95%CI：1.01 - 1.98）。年龄增长与牙齿脱落增加有关（OR：1.16；95%CI：1.03 - 1.31）。母亲教育程度低（OR：1.72；95%CI：1.13 - 2.61）、家庭收入低（OR：1.71；95%CI：1.09 - 2.67）以及自我感知的牙齿需求（OR：2.94；95%CI：1.97 - 4.39）也与该结果相关。定期看牙使牙齿脱落的可能性降低了38%（OR：0.62；95%CI：0.44 - 0.87）。在文盲率较高的城市观察到更大的牙齿脱落情况（OR：1.04；95%CI：1.01 - 1.08）。拥有更大牙科专科中心的城市与该结果相关（OR：0.58；95%CI：0.37 - 0.92）。背景因素和个体因素影响了巴西米纳斯吉拉斯州青少年的牙齿脱落情况，但社会经济地位是主要决定因素。
