To assess the changes in stress levels, social behavior, dietary and parafunctional habits, oral hygiene, among other conditions perceived by dental students in Brazil during the Covid-19 pandemic and evaluated the correlations between stress level and other variables.
An online questionnaire was developed and validated. Undergraduates enrolled in private and public dental schools were recruited by convenience sampling. Data were collected on the perceived changes regarding stress levels, financial and social characteristics, dietary habits, oral hygiene, health conditions, and parafunctional habits. Quantitative variables were expressed as absolute and relative frequencies. Wilcoxon test evaluated comparisons between perceived changes, and correlations between changes in stress levels and other variables were analyzed by Spearman correlation (α = 0.05).
A total of 638 dental students, mean age of 22.95 ± 4.10 years, participated in the study. During the pandemic, the reported stress levels increased while household income decreased (p < 0.05). Late dinners and mindless eating increased in frequency, whereas oral hygiene decreased (p < 0.05). Most of the health conditions and parafunctional habits assessed changed (p < 0.05). Perceived stress levels showed poor negative correlations with household income (rS = -0.14), poor positive correlations with the pressure to contribute financially in the household (rS = 0.19), and poor positive correlations with food choice frequency (rS = 0.15) (p < 0.05).
Dental students reported perceived changes in stress levels, dietary habits, oral hygiene, health conditions, parafunctional habits, and social behavior. Moreover, the results showed poor correlations, as students with higher stress levels tended to have the lowest household income, feel pressured to contribute financially in the household, and present a high meal intake frequency.
评估巴西牙科学生在 COVID-19 大流行期间压力水平、社会行为、饮食和口颌习惯、口腔卫生等方面的变化，并评估压力水平与其他变量之间的相关性。
开发并验证了在线问卷。通过便利抽样，招募了私立和公立牙科学校的本科生。收集了关于压力水平、财务和社会特征、饮食习惯、口腔卫生、健康状况和口颌习惯感知变化的数据。定量变量表示为绝对和相对频率。Wilcoxon 检验评估了感知变化之间的比较，Spearman 相关分析（α=0.05）分析了压力水平变化与其他变量之间的相关性。
共有 638 名牙科学生参与了研究，平均年龄为 22.95±4.10 岁。在大流行期间，报告的压力水平增加，而家庭收入减少（p<0.05）。晚餐时间延迟和无意识进食的频率增加，而口腔卫生则下降（p<0.05）。评估的大多数健康状况和口颌习惯都发生了变化（p<0.05）。感知压力水平与家庭收入呈负弱相关（rS=-0.14），与家庭经济压力呈正弱相关（rS=0.19），与食物选择频率呈正弱相关（rS=0.15）（p<0.05）。
牙科学生报告了压力水平、饮食习惯、口腔卫生、健康状况、口颌习惯和社会行为的感知变化。此外，结果显示相关性较差，因为压力水平较高的学生家庭收入较低，感到有经济压力，并且摄入的食物频率较高。
