Impact of Social Support on Perceived Stress in Latin American and Caribbean Dental Students and Dental Practitioners during Mandatory Social Isolation within the Coronavirus Pandemic in 2020

OBJECTIVE: To determine the impact of social support on perceived stress in Latin American and Caribbean dental students and dental practitioners during mandatory social isolation within the coronavirus (COVID-19) pandemic in 2020. METHODS: A cross-sectional study was conducted with a sample of 1812 dental students and dental practitioners from 21 Latin American and Caribbean countries. Perceived stress was assessed using the perceived stress scale (PSS-14), and the influence of social support was addressed using the Duke-UNC-11. Additionally, sociodemographic variables, knowledge of and preventive behaviour against COVID-19 and health status were considered. A descriptive, bivariate and multivariate analysis was performed through multiple linear regression. RESULTS: In the multivariate analysis, model 4 presented R2% = 21.20 (P < 0.001), a constant of 40.049; within the model, the social support variable had a non-standardised regression coefficient (b) of -4,527 (95% CI - 5.646 to -3,408; P < 0.001), the self-perceived level of concern regarding COVID-19 was b = 1.838 (95% confidence interval [CI] 0.887 to 2.790; P < 0.001), the self-perceived health status was b = -2.191(95% CI -2.944 to -1.437; P < 0.001), the number of days in compulsory isolation was b = -0.965 (95% CI -1.908 to -0.022; P = 0.045), while the level of confinement was b = 0.923 (95%CI: 0.106-1.740; P = 0.027), age was b = -1.743 (95% CI -2.625 to -0.860; P < 0.001), sex was b = 1.324 (95% CI 0.311 to 2.337; P = 0.011) and the economic income level was b = -1.539 (95% CI -2.434 to -0.644; P = 0.001). CONCLUSION: An association was determined between perceived stress and social support, as well as the variables of concern about the disease, self-perceived health status, number of days and level of confinement, age, sex and economic income level, based on the experience of dental practitioners and dental students in mandatory isolation.
