Gomes Leonardo Bonisson Maria Cristina Paixão Janaina Moutinho Costa Clareci Silva Cardoso Karla Santo Antonio Ribeiro Maria Auxiliadora Martins Milena S. Marcolino

Abstract

Background

Controlling blood pressure and glycemic levels is a challenge that requires innovative solutions.

Objective

To assess the feasibility of implementing a text message intervention among low-income primary care patients, as well as to assess self-reported behavioral change.

Methods

A set of 200 text messages was developed on healthy eating, physical activity, adherence, and motivation. Participants from Vale do Mucuri, MG, Brazil diagnosed with diabetes or hypertension or undergoing screening for those diseases, received 5 to 8 messages per week for 6 months. They answered a questionnaire to report their satisfaction and behavioral changes.

Results

Of the 136 patients, 117 (86.0%) answered the questionnaire. Most reported that the messages were very useful (86.3%), easy to understand (90.6%), and were very helpful for behavioral change (65.0%); 84.6% reported that they had started eating healthier. The most frequent reported lifestyle changes were: improved diet quality (85.5%), reduced portions (65.8%), and weight loss (56.4%). The majority of patients shared the messages (60.7%) with family or other acquaintances, considered the number of messages to be adequate (89.7%) and would recommend the program to others (95.7%).

Conclusion

An intervention based on text messages to promote behavioral change in patients with hypertension or diabetes in primary care is feasible in low-resource settings. Future studies are needed to assess the program’s long-term effects on clinical outcomes.

Weight Excess: The Great Villain in the Development of Hypertension in Adolescents

Erika Maria Gonçalves Campana et al. Maria Eliane Campos Magalhães Andréa Araujo Brandão

The relationship between arterial hypertension (AH) and excess weight in young populations is well established. This association involves several conditions including hyperinsulinemia, altered adipokine profile, elevated markers of subclinical inflammation, and inadequate habits, including physical inactivity.^–

In a study^– conducted in the city of Rio de Janeiro, Brazil, an increased body mass index in adolescents was correlated with a higher prevalence of elevated blood pressure (BP) and higher risk of developing AH at young adult age. From a longitudinal perspective, an interesting aspect in the assessment of cardiovascular risk factors is the tracking effect, in which children and adolescents with altered clinical and metabolic parameters (BP, body mass index and cholesterol levels) are likely to maintain an abnormal profile of these variables throughout life and become adults at increased cardiovascular risk.^– This fact highlights the continuous, unfavorable impact of persistent obesity from childhood to adulthood on cardiovascular risk factors.

Small Exercise Breaks can Save your Brain from Prolonged Sitting

A sedentary lifestyle is one of the major risk factors for the development of cardiovascular diseases. For instance, in 2019, stroke was the second-leading cause of death, as well as the primary cause of death and disability combined in the world. Active commuting to work is one strategy to decrease sedentary time and its impact, and the COVID-19 pandemic has changed work and daily routines worldwide. Moreover, the necessary social distancing has led to increased sedentary time, especially for those who are engaged in office desk work .

Acute prolonged sitting seems to lead to transient impairment of the endothelial function in the healthy population, whether this phenomenon is related to cardiovascular or cerebrovascular events is unknown. Nonetheless, prolonged sitting impairs the cerebrovascular function.^, Conversely, exercise breaks from prolonged sitting seem to restore the endothelial and cerebrovascular function. Therefore, active breaks from prolonged sitting could be a good strategy to mitigate the effects of sedentary time. However, the ideal duration and intensity need further investigation. Additionally, the difficulty to implement exercise breaks as a daily routine for office workers must be considered.

Is Patient Education about the Benefits of Physical Activity a Good Adjunct Treatment Strategy in Hypertension?

Dário C. Sobral Filho et al. Maria de Fátima Monteiro

Systemic arterial hypertension (SAH) is a chronic condition that is highly prevalent worldwide. It occurs without symptoms in most individuals and represents the main modifiable risk factor for cardiovascular disease. The adoption of behaviors that do not involve medication, such as changes in lifestyle and regular practice of physical exercise, along with strict adherence to prescribed medication, is a major challenge in the treatment of this disorder.^,

The guidelines of the American Heart Association and the American College of Cardiology on hypertension recommend the implementation of lifestyle changes as the first line of treatment for low- to moderate-risk groups, thereby emphasizing the importance of such measures.

Effects of Physical Exercise on Lipid and Inflammatory Profile of Women Using Combined Oral Contraceptive: A Cross-Over Study

Vinícius Afonso Gomes et al. Marvyn de Santana do Sacramento Lucas Mendes Santa Cecilia Daniela Santos de Jesus … Juliane Santos Barbosa Fernanda Oliveira Baptista de Almeida Elaine Carvalho de Oliveira Jefferson Petto

Abstract

Background:

The use of combined oral contraceptives (COC) is a risk factor for atherosclerotic disease, and physical exercise can minimize this condition.

Objective:

To verify if high intensity interval training (HIIT) promotes changes in the lipid and inflammatory profile of women using COC.

Methods:

Sequential crossover study with women aged 20-30 years, classified as irregularly active by the international physical activity questionnaire (IPAQ), when using COC. A physical-clinical assessment was performed with anthropometric measurements, VO_2max, and analysis of lipid and inflammatory profile. Participants were divided into 2 groups: the initial intervention group (GII), which began practicing HIIT for 2 months, and the posterior intervention group (GIP), which remained inactive for the same period. The GII and GIP would then alternate their conditions. The collected data was divided into: Initial moment (IM), post-exercise moment (PEM) and post-inactivity (PIM). The statistical analyses were performed using the Statistical Package for the Social Sciences, adopting a significance level of p <0.05 .

Results:

Twelve women were evaluated. After crossing the GII and GIP data, there was a difference in the C-reactive protein values between the IM of 4 (1.6-6.3 mg/dL) vs. PEM 2 (1.5-5 mg/dL); as well as between the PEM vs. the PIM= 4 (1.5-5.8 mg/dL), with a p -value = 0.04 in the comparisons. There was no change between the “moments” of the lipid profile, although it was possible to notice a reduction in resting HR and an increase in indirect VO_2max.

Conclusion:

The HIIT program was able to reduce the inflammatory profile, but it did not alter the lipid profile of irregularly active women using COC.

Family History of Hypertension: Impact on Blood Pressure, Anthropometric Measurements and Physical Activity Level in Schoolchildren

Tatiana Affornali Tozo et al. Beatriz Oliveira Pereira Francisco José de Menezes Junior Cristianne Morgado Montenegro … Carla Marisa Maia Moreira Neiva Leite

Abstract

Background:

A family history of arterial hypertension (AH), combined with environmental risk factors, is directly related to the development of AH.

Objectives:

To evaluate the frequency of AH, anthropometric indicators and level of physical activity and their association with a family history (FH) of AH in school children.

Methods:

Cross-sectional study with 118 students, aged between 11 and 17 years, of both sexes. Waist circumference (WC), weight, height, level of physical activity and FH of HA were collected. Body mass index z score (BMI-z) and waist-to-height ratio (WHtR) were calculated. Binary logistic regression model was used to verify the chance risk, with significance p <0.05.

Results:

Of the 118 parents who answered the questionnaire, 34.7% had a positive FH of AH. Girls with a positive FH had higher means of WC (p= 0,004), BMI (p=0,020), and systolic blood pressure (SBP) (p=0,006) than boys, and a higher risk of being overweight (OR=4,48; 95%CI:1,55–12,94), and having elevated WHtR (OR=5.98; 95%CI:1.66– 21.47) and SBP (OR=3,07; 95%CI:1,03–9,13) than girls without a FH, but they practice more vigorours moderate physical activity (MVPA) (p=0,039). On the other hand, no differences in these parameters were observed between boys with and without a FM of AH.

Conclusion:

Overweight and a FH of hypertension were associated with an increased risk for AH in girls. This was not observed among boys, perhaps due to more active lifestyle.

Home Physical Activity Programs for Children and Adolescents as a Healthy Strategy During Social Isolation Caused by COVID-19: viewpoint

Rafaela Catherine da Silva Cunha de Medeiros et al. Isis Kelly dos Santos Jason Azevedo de Medeiros Ricardo Ney Cobucci … Tatiane Andreza Lima da Silva Juliany de Souza Araujo Phelipe Wilde de Alcântara Varela Breno Guilherme de Araújo Tinoco Cabral Paulo Moreira Silva Dantas

Background

The recent outbreak of coronavirus disease (COVID-19) is considered a global health emergency. The global impact of this viral infection is of great concern to everyone. As the COVID-19 outbreak continues to appear unstoppable, preventive and hygiene measures have been implemented to safeguard against infection. Among these precautions, social isolation is considered to have the greatest potential for reducing contagion, at least until a vaccine becomes available. This isolation measure works as a kind of “necessary evil” for preventing a wide-reaching disaster. Thus, social distancing and staying home remain the most effective restrictive measures to prevent the exponential increase in contagion.

One of the crucial focal points of this strategy was oriented toward the closure of schools, thus affecting thousands of children and adolescents, who comprise approximately half of the global student population. The closure of educational institutions could have a significant impact on their lives, requiring them to adapt to new routines. Considering that they are now being confined to their homes due to the new situation generated by the pandemic, this cohort may experience moments of stress.

Does Hypertension Knowledge Influence Levels of Physical Activity in Hypertensive Patients From a Southern Brazilian Community?

Rafaella Zulianello dos Santos et al. Andrea Schaefer Korbes Eliara Ten Caten Martins Mateus De Lucca … Leonardo De Lucca Marlus Karsten Magnus Benetti

Abstract

Background:

Increased level of physical activity (PA) and health education are known as non-pharmacological treatments of hypertension (HP). There is a lack of studies investigating the influence of HP knowledge on the level of PA among hypertensive patients.

Objective:

To examine the influence of patient’s knowledge about HP on PA level and the relationship between these variables.

Methods:

A cross-sectional study was conducted in in a primary care center located in a city in the southern Brazil. A total of 199 hypertensive patients (median 61.2 [13] years; body mass index (BMI) 21.9 (7.5) kg/m2; 72.4% women) were included. The level of PA was assessed by measuring the number of steps taken daily. The knowledge about HP was assessed by a standardized questionnaire (HIPER-Q). The Kruskall-Wallis test was used to compare age, BMI and PA level between HP knowledge categories, and the Spearman test was used to assess correlations (p <0.05).

Results:

The median score of knowledge about HP for patients categorized as insufficient (n=6, 3%), poor (n=24; 12.1%), acceptable (n=101; 50.8%) and good (n=68; 34.2%) was 11.0 (8.0), 20.0 (4.0), 26.0 (5.0) and 38.0 (2.0), respectively. No patient has achieved an “excellent” level of knowledge. There was no significant difference in PA level (p = 0.341), BMI (p = 0.510) or age (p = 0.073) between these categories. Age was negatively correlated with knowledge about HP (p <0.05 and rho = 0.02).

Conclusions:

Patient’s knowledge about HP did not influence the level of PA in hypertensive patients. Age, number of steps per day and BMI were not significantly different between the categories of knowledge. Public policies and organizational strategy should be addressed to improve health education and avoid sedentary behavior in this population.

A Burden of Physical Inactivity in School-Age Students: The Early Beginning of Cardiometabolic Risk

Pedro Paulo da Silva Soares et al. Gabriel Dias Rodrigues

It is well-known that sedentarism has a close association with the risk of cardiovascular and metabolic diseases. The physical inactivity lifestyle contributes to the prevalence of obesity and hypertension in children, highlighting a big health problem since most individuals who were hypertensive and obese in childhood/adolescence become hypertensive and obese adults. On the other hand, physical exercise is a frontline non-pharmacological strategy to control and treat hypertension, as well as to prevent obesity, which should be encouraged among children/adolescents to reduce cardiometabolic risk in adulthood. In this context, the mapping of risk factors associated with hypertension at the early age should be considered a primary step to plan public policies for disease prevention and health promotion, reducing the burden on healthcare resources. Both obesity and high blood pressure have multifactorial causes, among them low levels of physical activity in adults, children, and adolescents. It is of utmost relevance to investigate the prevalence of physical activity levels in scholars, mainly in a country such as Brazil, with enormous disparities among regions.

In the current issue of the International Journal of Cardiovascular Sciences, Azevêdo et al. investigated physical activity levels, as well as the anthropometric and cardiovascular profile in school-age students attending public schools in the state of Sergipe, northeast of Brazil. The study reported high rates of physical inactivity for both boys and girls, and increased blood pressure in overweight school-age students. Regarding anthropometric profiles, intriguing data showed a high prevalence of low body weight in the age group from 16 to 17 years for both sexes. In contrast, a previous study found a high prevalence of overweight/obesity in school-age students in a city of the Brazilian South region, suggesting a discrepancy between the Brazilian South and Northeast regions that must be considered for Brazilian public policies in health promoting at the primary care level. From a practical perspective, physical education classes, as well as the public schools’ pedagogic programs, must work together for health promoting and health education, and physical activity should be encouraged to prevent cardiovascular risk starting from childhood to adult life.

Physical Activity, Exercise and Sports and Covid-19: What Really Matters

Claudio Gil Soares de Araújo

The ability to move is essential for an independent life. It is widely recognized that those who spend the most time either lying down or sitting and are physically inactive tend to have limited autonomy, poor health-related quality of life, and adverse prognosis of outcomes.

This editorial will briefly discuss the relationship between COVID-19 and physical movement. To better address this important relationship and for sake of clarity, some concepts should be defined first. In sport and exercise sciences, “physical activity” is defined as any bodily movement produced by skeletal muscles that results in energy expenditure, “exercise” is a subset of physical activity that is planned, structured, and repetitive and “sport” is an activity that most often, but not always, involves exercise and predetermined rules and participation in games or races or competitions.

Impact of Continuing Education on the Quality of Blood Pressure Measurement

Erika Campana et al. Bruno Daniel Ferrari

Cardiovascular diseases are the leading cause of death worldwide, and a key risk factor for these diseases—hypertension—is unquestionably the most prevalent disease in the population. Cardiovascular semiology is extremely important in the setting of hypertension (HTN), since the determination of blood pressure values through established indirect measurement techniques plays an essential role in initiating further diagnostic investigation, prompting treatment, and allowing monitoring of patients with HTN. The environment in which measurement is performed; the patient’s dietary habits, use of tobacco and alcohol, and engagement in physical activity before measurement; the adequacy of cuff size in relation to the limb; and proper cuff positioning are among the several important aspects which may interfere with measurement reliability. In this context, assessing the technical knowledge of healthcare providers is critical to preventing diagnostic errors.

Differences in magnitude between office BP and mean daytime BP can be attributed both to the environment and to the technical quality of blood pressure measurement by the examiner. Beckett et al. obtained an average of three manual BP readings from 481 hypertensive patients in family practices. The average clinic BP (151/83 mmHg) was significantly (P<0.001) higher than the daytime mean BP measured by ambulatory blood pressure monitoring (ABPM) (142/80 mmHg).

Should Physical Activity Be Considered Essential During the COVID-19 Pandemic?

Francisco José Gondim Pitanga et al. Carmem Cristina Beck Cristiano Penas Seara Pitanga

Introduction

The novel coronavirus (COVID-19) disease, considered a pandemic by the World Health Organization (WHO), which until April 13, 2020, had 1,776,867 confirmed cases with 111,828 deaths worldwide, led the Ministry of Health of Brazil to prepare a manual with several actions to prevent the spread of the disease. Among these actions, social distancing is recommended, instructing people to remain at home. In addition, many heads of state and municipal executive power across Brazil have issued decrees proposing the closure of several spaces, including gyms, clinics, clubs, and other public and private spaces for physical activity. These actions caused the Brazilian population to have difficulties to continue the practice of physical activity.

On the other hand, since the beginning of the pandemic, some studies have been published in different parts of the world, calling attention to the importance of continuing to practice physical activity. For example, in the city of Wuhan in China, the initial epicenter of the disease, people were recommended to practice physical activity even at home. In a recent study focused on elderly people, outdoor physical activity and also exercising at home were suggested as therapy to combat the physical and mental consequences of quarantine due to the Covid-19 pandemic. In addition, according to a recent position of the American College of Sports Medicine, people should continue to stay physically active while at home during the pandemic.

Coronavirus Disease (COVID-19) Pandemic: An Opportunity Window to Implement Home-Based Cardiac Rehabilitation

Renata Rodrigues Teixeira de Castro

The World Health Organization declared that the new coronavirus outbreak is a public health emergency of pandemic proportions. The outbreak has caused various governments to take protective measures such as lockdown of cities, travel bans, prohibition of group gatherings and public events, and social distancing. Many health and exercise training facilities were closed, as well as cardiac rehabilitation services. These restrictions are disrupting people’s daily activities.

Although staying at home can contain virus spread, it will certainly reduce regular physical activity and increase sedentary behavior, which can increase the risk of development and worsening of chronic conditions.^– Therefore, there is a strong evidence for continuing physical activity at home even during the pandemic situation.

Self-perception and dissatisfaction with weight does not depend on the frequency of physical activity

Denise Sardinha Mendes Soares de Araújo et al. Claudio Gil Soares de Araújo

OBJECTIVE: To evaluate the level of satisfaction with body weight and the self-perception of the weight/height ratio and to verify the influence of the frequency of present and past physical activity on these variables. METHODS: Using questionnaires or interviews, we obtained height data, reported and desired weight, self-perception of the weight/height ratio, and the frequency of current physical activity in 844 adults (489 women). Of these, evaluated the frequency of physical activity during high school of 193 individuals,and we measured their height and weight. RESULTS: Less than 2/3 of the individuals had body mass index between 20 and 24.9 kg/m2. A tendency existed to overestimate height by less than 1 cm and to underestimate weight by less than 1kg. Desired weight was less than that reported (p<0.001), and only 20% were satisfied with their current weight. Only 42% of men and 25% of women exercised regularly. No association was found between the frequency of physical activity and the variables height, weight, and body mass index, and the level of satisfaction with current weight. CONCLUSION: Height and weight reported seem to be valid for epidemological studies, and great dissatisfaction with body weight and a distorted self-perception of height/weight ratio exists, especially in women, regardless of the frequency of physical activity.
