The aim of this study was to compare the levels of anxiety and social support evaluated in pregnancy before and during the COVID-19 pandemic. This study was designed prospectively and observationally. Participants were asked to fill in two different questionnaire forms for the Multidimensional Scale of Perceived Social Support and The State-Trait Anxiety Inventory. Independent t-test and Pearson correlation analysis were used for statistical analysis. The mean age of 386 pregnant was 29.1 ± 4.91 years, and the gestational week was 29.12 ± 4.54. The values of the total social support scale were determined 61.52 ± 5.53-51.15 ± 5.86 before and during the pandemic, while the total state anxiety scale was found 39.81 ± 9.04 and 63.38 ± 10.55, respectively. The total trait anxiety scale was found at 38.23 ± 7.39 and 53.22 ± 8.74 in the same respect. A significant difference was obtained in the data between before and during the pandemic (p < .05). The study showed that pregnant are deprived of social support and their anxiety levels increase during the COVID-19 pandemic.IMPACT STATEMENTWhat is already known on this subject?

Social support is an important determinant of physical and psychological well-being, especially during pregnancy when individuals take on new responsibilities and roles.What do the results of this study add? The study showed that pregnant women were deprived of social support and their anxiety levels increased during this pandemic. The results highlight that there is a high need to mitigate mental health risks and adjust interventions under pandemic conditions.What are the implications of these findings for clinical practice and/or further research? It is necessary to provide social support from family, friends, and close circles. States and health professionals need to put forward serious programs and studies to reduce the stress and anxiety experienced by the society and especially pregnant women and to provide accurate information about COVID-19.
