OBJETIVO: Investigar a prevalência da desnutrição e fatores associados em crianças menores de 60 meses em dois municípios do Estado do Acre. MÉTODOS: Estudo transversal de base populacional realizado com 667 crianças da área urbana dos municípios de Acrelândia e Assis Brasil. A prevalência da desnutrição foi calculada pelo padrão de crescimento da Organização Mundial da Saúde de 2006, com o ponto de corte -2 escores Z. Informações sobre condições socioeconômicas, acesso aos serviços e cuidado da criança, peso ao nascer e morbidade foram obtidas por questionário estruturado. A regressão de Poisson foi utilizada para identificar os fatores associados à desnutrição de crianças. RESULTADOS: A prevalência do déficit estatura para idade e déficit peso para estatura foi de 9,9% e 4,1%, respectivamente. Os fatores associados ao déficit estatura para idade foram o baixo índice de riqueza (razão de prevalência [RP]: 1,74; intervalo de confiança em 95% [IC95%]: 0,95 - 3,18), analfabetismo do pai ou padrasto (RP: 1,82; IC95%: 1,01 - 3,27), ter 2 ou mais irmãos menores (RP: 2,88; IC95%: 1,45 - 5,72), ausência da mãe biológica no domicílio (RP: 2,63; IC95%: 1,32 - 5,24) e exposição ao esgoto a céu aberto no âmbito domiciliar (RP: 2,46; IC95%: 1,51 - 4,00). Somente o baixo peso ao nascer mostrou-se como fator associado ao déficit peso para estatura (RP: 2,91; IC95%: 1,16 - 7,24). CONCLUSÕES: Nos municípios estudados, a desnutrição em crianças menores de 60 meses apresenta-se como um importante problema de saúde pública, associado aos indicadores de iniquidades sociais, acesso aos serviços de saúde e ausência da mãe no domicílio.

Objective: Analyze the prevalence and factors associated with internet addiction in a sample of high school adolescents in Acre, a state in northern Brazil. Methods: A population-based cross-sectional study was conducted with 1,387 adolescents between 14 and 18 years old enrolled in high schools in the city of Rio Branco, Acre. A structured questionnaire with questions about demographics, family and behavioral patterns was applied. Internet addiction was verified using the Internet Addiction Test (IAT), with a cutoff equal to or greater than 70 points. The associated factors were identified by multiple logistic regression analyses. Results: The overall prevalence of Internet addiction was 10.6%. Higher dependence was observed in females. The factors associated with Internet addiction were being female, using the computer for more than two hours a day during weekdays and on the weekend, not practicing physical activities and going out to dance at nightclubs and concerts at least once a month. A protective association of reading habits in relation to Internet dependence was observed. Conclusions: The present study showed a high prevalence of Internet dependence, with female adolescents being more susceptible. Behavioral aspects were associated with internet dependence in a sample of adolescents from Rio Branco, Acre.

Describe educational practices performed by health professionals with reference to the paradigm of health promotion. It is systematic review the search for articles in databases: Medline, Lilacs and SciELO, published during the period from 2003 to 2013. The search was performed using the integrated method, using the terms: health promotion, health education and experiences. Given the results, was possible to demonstrate the importance of conducting health education experiences in different contexts: primary care, hospitals and schools with various themes and methodologies adopted. However, although these experiences implemented primarily with a view to promoting health, highlighting elements such as autonomy, empowerment and decision-making, it was found that even if educational actions on normative health are carried out they weaken the process of the empowerment of the individuals involved.

Introduction: Stroke is a significant cause of death worldwide. Temporal studies show a downward trend in mortality rates in recent decades, with variability between countries. The State of Pará, in northern Brazil, has a low human development index and high mortality from stroke; however, little research is reported. Objective: This study aims to analyze the trend in stroke mortality in the adult population of Pará, between 2000 and 2021. Method: This is an ecological, time series study based on official secondary population data. Joinpoint regression models were used to identify the trend of each coefficient segment of the mortality rate and years of potential life lost. Results: There were 49,259 deaths in this period, with an absolute increase in fatalities during the time series and an increase in the age group. The mortality coefficient showed a stationary mortality trend of 0.4% between 2000 and 2021 (p=0.576); however, after 2008, the trend decreased -1.0% (p=0.003). In the stratified analysis, a decreasing mortality trend was detected: -2.3% between 30 and 39 years old (p<0.001), -2.8% between 40 and 49 years old (p<0.001), -2.1% between 50 and 59 years old (p<0.001) and -1.4% between 60 and 69 years old (p<0.001), between the year 2000 and 2021. In the other age groups, the trend decreased -2.5% between 20 and 29 years old after 2006 (p= 0.003), -1.8% between 70 and 79 years old after 2008 (p=0.001), and -5.1% among 80 years old and over after 2016 (p=0.010). Conclusion: The mortality trend attributed to stroke among adults in Pará State remained stable from 2000 to 2021. Despite this stability, the absolute number of deaths remained consistently high, underscoring the critical need to mitigate risk factors and enhance the care and management of affected individuals.

Stroke is the second leading cause of death and disability in Latin America; however, few epidemiological studies have been conducted in South America. An observational study was conducted to analyze trends in stroke mortality in South American (SA) countries. Age-standardized mortality rates and proportional mortality due to stroke in the populations of SA countries between 1990 and 2019 were assessed by extracting data from the Global Burden of Disease 2019 study. Joinpoint regression models were employed to identify trends in the annual percentage change in mortality rates for each segment. Considering the data collected over the 30 years that were studied, the age-standardized stroke mortality trend decreased in Argentina (−1.6%), Uruguay (−0.6%), Brazil (−0.5%), Guyana (−0.5%), and Bolivia (−0.4%), while Venezuela (+1.6%) and Suriname (+1.0%) showed an increasing trend. The proportional stroke mortality trend decreased in Argentina (−1.7%), Paraguay (−0.9%), Uruguay (−0.7%), Guyana (−0.7%), Brazil (−0.5%), and Chile (−0.5%), whereas Bolivia (+1.0%), Suriname (+0.6%), and Peru (+0.4%) exhibited an increasing trend. The trends in stroke mortality between 1990 and 2019 demonstrated considerable variability. While most SA countries experienced significant decreases in stroke mortality trends, Venezuela and Suriname showed increases in age-standardized mortality rates, and Bolivia, Suriname, and Peru exhibited increases in proportional mortality rates. No decreasing stroke mortality trend was observed in the segment after the last joinpoint, highlighting the need for improvement in prevention and treatment.

Objective: To review the epidemiological evidence of the association between sleep duration and blood pressure in adolescents. Data sources: We performed a systematic review of observational studies in Medline, Scopus, Lilacs, Web of Science, Science Direct databases and Virtual Libraries in English, Spanish and Portuguese published until September 2018. Studies were selected first by title and abstract, then by complete reading, according to the eligibility criteria. The reference list of selected articles was evaluated in order to retrieve relevant studies. Data synthesis: Initially, 1,455 articles were retrieved. After exclusion due to duplicity or not meeting the eligibility criteria, 13 articles were included in the review. Studies varied greatly in sample size (143 to 6,940 patients), methods of measuring blood pressure and sleep duration, cutoff points, categorization and adjustment of variables. The main evidence from the studies is that short sleep duration is associated with high blood pressure in adolescence, although the presence of association between high blood pressure and long sleep duration is possible, but not clear in the literature. Conclusions: Sleep duration, especially short duration, is associated with high blood pressure in adolescents. Such evidence draws attention to implications on cardiovascular health in this age group.
