Objective: To analyze the level of knowledge, attitudes, and practices of Mozambican public employees on the prevention of COVID-19. Methodology/Approach: 126 Mozambican public employees (79 men, 43 women and 4 who chose not to disclose their gender) answered a closed questionnaire applied through the Google Form online platform. The questionnaire was open for 5 days (two weekend and three business days). Findings: The results suggest that employees are knowledgeable; however, efforts should be made to carry out educational actions to improve attitudes and change practices related to the prevention of COVID-19. Research limitation/implications: Existence of some respondents who are not public employees due to online data collection, who were excluded from the study. Originality/Value of the article: The conclusions of the study serve as a means of punctual intervention for Mozambican health entities as well as illustrating specific areas of concentration in education for the prevention of COVID-19. On the other hand, they enrich the specific scientific field, which is still empty of knowledge.

Introduction: physical inactivity is a risk factor for chronic non-communicable diseases, causing morbidity and mortality and weight gain in the economy of nations. Objective: to analyze the effect of combined physical exercises on anthropometric and hemodynamic parameters in young and adults people in Cidade da Matola. Methodology: 22 subjects from 23 to 60 years old (8 female and 14 male) were randomly selected in 2017. The anthropometric assessment consisted of weight, height, BMI and waist circumference. Hemodynamic variables were evaluated with an Omron M3-HEM-7131-E tensiometer. The sample performed combined physical exercises for three consecutive months. Using SPSS, 20.0, at 95% CI, the non-parametric WILCOXON test was applied to examine the effect of physical exercises on the variables of interest. Results: globally, weight and BMI increased over the course of the intervention, however without statistical differences, on the other hand, height, WP, SBP, DBP and HR differed statistically: P=(0.019; 0.008; 0.048; 0.006; 0.000) respectively. After analyzing the sex, only male individuals registered statistically significant differences for WP, DBP and HR: P=(0.023; 0.006; 0.000) respectively. The age range of individuals aged ≥ 36 years revealed a significant effect of the intervention on the variables WP, DBP and HR: P=(0.022; 0.042; 0.001) respectively. Conclusions: although the sample size was small, globally, the effect of the intervention on the variables of interest was notorious, especially in Blood Pressure, Heart Rate and Waist Perimeter.

In the middle of December 2019, COVID-19 appeared in the Chinese City of Wuhan. It is a pathology that quickly spread around the world, counting, until the completion of the present study, with more than 2 million infected and about 140 thousand dead. The aim of the present study was to analyze knowledge, attitudes and practices of public workers from Mozambique on the prevention of COVID-19. To this end, 126 public workers in Mozambique (79 men, 43 women and 4 who chose not to disclose their gender) answered a closed questionnaire applied to the Google Form online platform. The questionnaire was open for 5 days (two weekend days and three business days). The results revealed that most employees have basic knowledge and appropriate measures for the prevention of COVID-19, more than half adopt behaviors conducive to disease prevention and less than half effectively comply with preventive actions guided by governmental and the health sector. The results suggest that public officials are knowledgeable, however efforts should be made to carry out educational actions to improve attitudes and change practices related to the prevention of COVID-19.
