Abstract Background: Sarcopenia is a disease that involves skeletal muscle mass loss and is highly prevalent in the older adult population. Moreover, the incidence of sarcopenia is increased in patients with hypertension. Objectives: The study aimed to evaluate the association between the classes of the drugs used for arterial hypertension treatment and the presence or absence of sarcopenia. Methods: 129 older adults with hypertension were evaluated by the researchers who registered the participants medication for arterial hypertension treatment. Sarcopenia level was measured by anthropometric parameters, muscular strength, and functional capacity. The data were analyzed by one-way ANOVA followed by post-hoc test and Fisher’s exact test; statistical significance was set at 0.05. Results: Age was not different between women with different levels of sarcopenia, but significant differences were observed between men with absent sarcopenia (66.8±4.2 years) and men with probable sarcopenia (77.0±10.2 years). Individuals with absent sarcopenia showed higher handgrip strength (men: 33.8±7.4, women: 23.2±4.6 Kgf) in comparison with those with sarcopenia (men with probable sarcopenia: 9.5±3.3 Kgf, women with probable, confirmed, and severe sarcopenia: 11.7±2.5, 12.2±3.0, 11.8±1.8 Kgf, respectively). The analysis showed an association between the type of medication and degree of sarcopenia; diuretics were significantly associated with probable sarcopenia, and angiotensin II receptor blockers (alone or in combination with diuretics) was associated with absence of sarcopenia. Conclusion: In conclusion, handgrip strength was a good method to diagnose sarcopenia, and diuretics were associated with increased risk of sarcopenia in older adults with hypertension.

Background: A population study is an important tool that can be used to understand the actual epidemiological scenario of the Covid-19 in different territories, identify its magnitude, understand its transmission dynamics, and its demographic, geographical, and social distribution. Objective: The aim of this study was to determine the prevalence and dynamics of SARS-CoV-2 infection in the population of two Brazilian cities during the pandemic first wave and subsequent socioeconomic and health effects. Materials & methods: This paper described the methodological procedures adopted and the prevalence of the SARS-CoV-2 infection in the population. A household survey was conducted between October and December 2020, in two historic cities of Brazil's mining region. Anti-SARS-CoV-2 antibody was detected using the Wondfo® rapid test. The face-to-face interview consisted of administration of a questionnaire containing registration data, sociodemographic and economic variables, living habits, general health condition, mental health, sleep habits, and eating and nutrition. Results: We evaluated 1,762 residents, of which 764 (43.4%) were in Mariana and 998 (56.6%) in Ouro Preto. For both cities, 51.9% of the interviewees were female, with a predominance of the age range 35 to 59 years old (47.2%). The prevalence of the SARS-CoV-2 infection was 5.5% in all cities, 6.2% in Ouro Preto, and 4.7% in Mariana. The prevalence was similar between cities (P>0.05). Conclusion: The study was effective in verifying the seroprevalence of infection by the virus and its findings will enable further analyses of the health conditions of the population related to social isolation and the risk of infection with SARS-CoV-2.

RESUMO O desenvolvimento da criança é um processo contínuo, dinâmico e não linear, no qual o movimento configura uma das necessidades vitais do ser humano. Este estudo quase-experimental teve por objetivo analisar a magnitude da mudança no nível coordenativo de 43 escolares com idade entre 6 e 7 anos, de ambos os sexos, submetidos a dois distintos programas de intervenção de atividades físicas, separados em grupo experimental (GE) e grupo controle (GC). Para avaliar a coordenação motora utilizou-se o Körperkoordinationstest Test Für Kinder (KTK). Os dados foram submetidos à análise estatística aplicando-se os testes de normalidade e t - student (para amostras independentes e para amostras pareadas). Os resultados indicaram que, no geral, os meninos obtiveram escores médios superiores aos das meninas, e, houve um decréscimo nos níveis de coordenação em escolares com idade mais avançada. Além disso, constatou-se que o GE obteve índices mais elevados que o GC.

ABSTRACT Child development is a continuous process, dynamic and non-linear, in which the movement sets up one of the vital needs of the human being. This quasi-experimental study aimed to analyze the magnitude of change in the coordinative level of 43 schoolchildren aged between 6 and 7 years, of both sexes, subject to two distinct physical activity intervention programs, separated in the experimental group (GE) and control group (GC). To evaluate the motor control using the Körperkoordinationstest Test Für Kinder (KTK). The data were subjected to statistical analysis by applying the tests of normality and t-student (for independent samples and for paired samples). The results indicated that, in General, boys obtained average scores above those of girls, and there was a decrease in the levels of coordination in schools with older age. In addition, it was noted that the GE obtained higher that the GC.
