To study Oral Health related Quality of Life (OHRQoL) of pre-school children and its associated factors.
Cross-sectional study with sample data collected through an on-line questionnaire to a non-probabilistic sample. The questionnaire included the Portuguese version of the Early Childhood Oral Health Impact Scale (ECOHIS) and questions about sociodemographic characteristics, oral health behaviours, and reported oral health of the child. Data analyses included descriptive statistics, Mann-Whitney and Kruskal-Wallis tests and Linear regression (α = 0.05).
The sample consisted of 1475 parents of pre-school children (3-5 years-old), residing in Portugal. The mean ECOHIS total score was 1.5 (sd = 3.4). In the bivariate analysis the child's age, starting toothbrushing after one year of age, frequent intake of sugary food and drinks, previous appointment with an oral health professional, all reported of oral health problems, and a negative perception of oral health were negatively associated with OHRQoL (p < 0,05). In the regression model the factors that most contributed to a worse quality of life were dental caries and abscess, contributing to an ECOHIS average increase of 2.56 and 3.34, respectively.
The studied population presented a good OHRQoL, with the item related to pain being the most relevant for the ECOHIS score. Worst OHRQoL was found in older children, whose parents negatively rated the children's oral health and with reported dental caries, trauma, and abscess.
研究学龄前儿童的口腔健康相关生活质量（OHRQoL）及其相关因素。
采用横断面研究，通过在线问卷收集非概率样本的样本数据。问卷包括葡萄牙语版的幼儿口腔健康影响量表（ECOHIS）以及关于社会人口学特征、口腔健康行为和儿童报告的口腔健康状况的问题。数据分析包括描述性统计、曼-惠特尼检验和克鲁斯卡尔-沃利斯检验以及线性回归（α = 0.05）。
样本包括居住在葡萄牙的1475名学龄前儿童（3至5岁）的家长。ECOHIS总分的平均值为1.5（标准差 = 3.4）。在双变量分析中，儿童年龄、一岁后开始刷牙、频繁摄入含糖食物和饮料、之前与口腔健康专业人员预约、所有报告的口腔健康问题以及对口腔健康的负面认知与OHRQoL呈负相关（p < 0.05）。在回归模型中，对生活质量恶化影响最大的因素是龋齿和脓肿，分别导致ECOHIS平均增加2.56和3.34。
研究人群的OHRQoL良好，与疼痛相关的项目对ECOHIS评分最为重要。在年龄较大的儿童中发现OHRQoL最差，其父母对儿童口腔健康的评价为负面，且报告有龋齿、创伤和脓肿。
