To systematically review observational studies assessing the association between socioeconomic status (SES) and oral health-related quality of life (OHRQoL) in children, adolescents and adults.
Electronic searches were performed in the PubMed, Embase, Web of Science, LILACS and Scopus databases for articles published up to September 2020. Two independent reviewers performed the search and critical appraisal of the studies. The inclusion criteria were observational studies that evaluated the effect of SES on the OHRQoL in all age groups using validated methods. Quality assessment was conducted using the Newcastle-Ottawa Scale. Data were extracted for meta-analysis followed by a meta-regression analysis. A random-effects model was used to estimate the pooled calculate prevalence ratio (PR) and respective 95% confidence intervals (CI) for each study.
The search strategy retrieved 6114 publications. Some 139 articles met the eligibility criteria and were included in the systematic review. Of those, 75 were included in the general meta-analysis they represented a total sample of 109 269 individuals. People of lower SES had worse OHRQoL (PR 1.30; 95% CI 1.26-1.35). In the meta-analyses of different subgroups, an association was found between low SES and worse OHRQoL in countries of all economic classifications, in all age groups and irrespective of the socioeconomic indicator used. A socioeconomic gradient in OHRQoL was also observed, in which the lower the individuals' socioeconomic position, the poorer their OHRQoL.
Individuals of low SES had poorer OHRQoL, regardless of the country's economic classification, SES indicator and age group. Public policies aiming to reduce social inequalities are necessary for better OHRQoL throughout life.
系统评价评估社会经济地位（SES）与儿童、青少年和成年人口腔健康相关生活质量（OHRQoL）之间关联的观察性研究。
截至 2020 年 9 月，在 PubMed、Embase、Web of Science、LILACS 和 Scopus 数据库中进行电子检索，以查找发表的文章。两名独立审查员进行了搜索和研究评估。纳入标准为使用验证方法评估 SES 对所有年龄段 OHRQoL 影响的观察性研究。使用纽卡斯尔-渥太华量表进行质量评估。对数据进行提取以进行荟萃分析，然后进行荟萃回归分析。使用随机效应模型估计汇总计算患病率比（PR）和每个研究的相应 95%置信区间（CI）。
搜索策略检索到 6114 篇出版物。有 139 篇文章符合入选标准，并被纳入系统评价。其中 75 篇文章被纳入一般荟萃分析，共代表 109269 人的总样本。社会经济地位较低的人 OHRQoL 较差（PR 1.30；95%CI 1.26-1.35）。在不同亚组的荟萃分析中，在所有经济分类的国家、所有年龄组以及无论使用何种社会经济指标，均发现低 SES 与较差的 OHRQoL 之间存在关联。OHRQoL 也存在社会经济梯度，即个体的社会经济地位越低，其 OHRQoL 越差。
无论国家的经济分类、SES 指标和年龄组如何，社会经济地位较低的人 OHRQoL 都较差。需要制定旨在减少社会不平等的公共政策，以实现整个生命周期的更好的 OHRQoL。
