Depression and anxiety are common after months of social isolation, and they can have a negative impact on anyone's quality of life if they are not treated promptly and appropriately. The aim of this study was to determine if the change to online modality courses and the presence of depression or anxiety symptoms during the COVID-19 pandemic was associated with a difference in the college student’s academic achievement. This study was a cross-sectional survey in which we used the Patient Health Questionnaire-9 (PHQ-9) and the General Anxiety Disorder-7 (GAD-7). Also, we examined the students' perceptions of their academic performance using the Academic Self-Concept Scale (ASCS). A total of 610 students responded to the survey. The average score on the Academic Self-Concept Scale was 2.76 ± 0.35, the students presented a risk of 61.5% for possible depressive disorder and 52.1% for possible generalized anxiety disorder. The intensity of depression and anxiety symptoms had a significant effect on Academic Self-Concept Scale scores (p < 0.001 and p < 0.05, respectively). The findings indicate that the COVID-19 pandemic has had a direct effect on students' mental health and academic performance.

Social isolation and school closure may predispose adolescents to higher prevalence rates of depression, anxiety, and stress. In this cross-sectional observational study, the validated Spanish version of the Depression, Anxiety, and Stress Scale was administered to 3112 students aged 14–22 years old. We also collected data on participant gender, age group, school shift (morning or afternoon), school year, family type, whether they or any first-degree relative had been infected with COVID-19, whether any family member had died of COVID-19, and whether either of their parents worked. Mean scores were 8.34 ± 6.33 for depression, 7.75 ± 5.89 for anxiety, and 10.26 ± 5.84 for stress. Female students presented significantly higher scores on all three measures compared with male students. Students who had been infected with COVID-19, who had an infected family member, or who had a family member who died of COVID-19 also presented higher scores on all three measures. Identifying the symptoms and warning signs of depression and anxiety disorders is critical, particularly in vulnerable populations like adolescents.

Confinement and a lack of social interaction are associated with depressive symptoms, low self-esteem, and suicidal thoughts. We report the results of a cross-sectional survey of 1414 junior high school students. The aim was to evaluate the prevalence of depression, anxiety, and stress in Guadalajara, Mexico, during the COVID-19 pandemic. Mean scores on the validated Spanish version of the Depression, Anxiety, and Stress Scale (DASS-21) were found to be 6.15 ± 5.6 for depression, 5.8 ± 5.2 for anxiety, and 8.08 ± 5.3 for stress. Female students scored higher in all three conditions (p < 0.001). Students who had relatives infected with COVID-19 showed significantly more anxiety than those who did not (p < 0.004). Although certain demographic groups are at higher risk of manifesting depression, anxiety, and stress, the student population has also been affected by the global impact of the pandemic.

IntroductionUnderstanding how Mexicans behave during the pandemic could present a complete picture of the phenomenon in our country and provide better management of it.ObjectiveThis study aimed to analyze the Mexican population's behavior and preventive measures.MethodsThis was a cross-sectional study in which a total of 4,004 participants from the general population responded to the survey.ResultsAlmost 99% of the participants mentioned knowing the symptoms of COVID-19. Although 77.5% of participants considered that they followed proper social distancing measures, 60% of them mentioned that they knew at least six individuals who did not follow social distancing measures. Furthermore, 96.2% of participants reported using preventive measures at least 50% of the time. Only 51.3% used a certified mask.ConclusionThe COVID-19 pandemic outcomes in Mexico are the result of multiple negative factors, such as high rates of comorbidities, high number of people living together at home, many people breaking social isolation, and most of the population using non-certified preventive measures that may not be effective enough.
