Morbidity trend and space-time clusters of COVID-19 occurrence in children and adolescents.

OBJECTIVE: To analyze the morbidity trend and space-time distribution clusters of confirmed COVID-19 cases in children and adolescents. METHOD: An ecological study of COVID-19 cases confirmed in the Information System from 2020 to 2022 in the age group from 0 to 19 years old, residents in Mato Grosso municipalities, Brazilian Midwest region. A trend analysis of the monthly morbidity rate of cases/100,000 inhabitants was used, following Prais-Winsten's regression. A space-time distribution of the Bayesian incidence rate per 100,000 inhabitants was performed, in addition to a space-time scan to identify high-risk clusters. RESULTS: Of all 79,592 COVID-19 cases studied, 51.6% were in females and 44.21% in people aged 15-19 years old. The mean monthly rate was 265.87 cases per 100,000 inhabitants, with a stationary trend in the period analyzed (Monthly Percentage Variation [MPV]) = 12.15; CI95%[MPV]: -0.73;26.70). The morbidity rate due to COVID-19 was higher in the female gender (283.14/100,000 inhabitants) and in the age group from 15 to 19 years old (485.90/100,000 inhabitants). An increasing trend was observed with a greater monthly time variation of 14.42% (CI95%[MPV]: 1.28;29.28)] among those aged from 10 to 14 years old. The primary cluster, which was also the one with the highest Relative Risk (RR = 5,16, p-value = 0.001), included 19 municipalities located in the North health macro-region. CONCLUSION: The findings indicated a monthly stationary trend in the study population, an increase in the age group from 10 to 14 years old, and areas at a higher risk for the disease in the North health macro-region of the state.

Relationship between adolescent lifestyle and emotional and behavioral problems.

This study aimed at verifying the relationship between lifestyle and emotional and behavioral problems in adolescents. This is an observational and cross-sectional study developed with adolescents from a capital city in the Brazilian Amazon. Data collection was performed using an electronic form containing items from the Fantastic Lifestyle and Strengths and Difficulties Questionnaire instruments. For data analysis, the bootstrap t-Test and calculation of Cohen's d statistic value were performed to assess the effect size of the difference between means. A total of 479 adolescents participated in the study. There was a high relationship between emotional and behavioral problems and lifestyle (p < 0.01; d = 1.36), especially regarding emotional problems (p < 0.01; d = 1.09), hyperactivity (p < 0.01; d = 0.92) and peer problems (p < 0.01; d = 0.78). The lifestyle attributes that were highly related to emotional and behavioral problems were insight (p < 0.01; d = 1.30), sleep, seatbelt, stress and safe sex (p < 0.01; d = 0.93), type of behavior (p < 0.01; d = 0.86) and career (p < 0.01; d = 0.85). It is therefore concluded that there was a high relationship between lifestyle and emotional and behavioral problems among the adolescents surveyed. Thus, it becomes necessary to promote socio-emotional skills and restorative and health-protective lifestyles in this population.
