Nutritional Counseling Based on Mindful Eating for the Eating Behavior of People Living with Overweight and Obesity: A Randomized Clinical Trial

OBJECTIVES

This study aimed to evaluate the effect of a counseling approach based on Mindful Eating on the eating behavior of individuals living with overweight and obesity.

METHODS

A 16-week randomized clinical trial was conducted to compare an online group intervention (IG) with individual online nutritional counseling (TAU). Volunteers (n = 61), aged 18 or older with BMI ≥ 25 kg/m2, were randomly assigned to the two groups and invited to participate in eight biweekly sessions. Eating behavior was assessed using the Three-Factor Eating Questionnaire (TFEQ-21), and anthropometric measures were collected through self-report. Comparison between the groups was performed using generalized linear models and Poisson models with robust variance estimators. A sensitivity analysis was conducted to evaluate the group-by-time interaction. The study was approved by the UFCSPA Ethics Committee.

RESULTS

At baseline, the eating behavior domain with the highest mean score was emotional eating (EE) in both groups. At the end of the study, all domains decreased, while an increase in cognitive restraint (CR) was observed in the TAU group, showing a difference between the groups (-23.1; 95%CI -37.7 to -8.5; p = 0.004). A group-by-time interaction difference was noted only in the CR domain, explained by the change in the TAU group for the CR comparison before and after treatment and by the difference between the IG and TAU groups at the end of the treatment period.

CONCLUSIONS

A Mindful Eating approach may aid in managing dysfunctional cognitive restraint, a key component for sustainable excess weight treatment. The protocol can be found on ClinicalTrials.gov (NCT05845411).

The cost of obesity and related NCDs in Brazil: An analysis of hospital admissions, disability retirement benefits, and statutory sick pay

OBJECTIVES

This study analyses the prevalence of overweight/obesity in Brazil, and its costs regarding hospital admissions (HA), disability retirement benefits (DRB), and statutory sick pay (SSP) associated with obesity-related non-communicable diseases (NCDs).

STUDY DESIGN

Time-series study.

METHODS

This study analyses data from the VIGITEL system (2010-2019) to calculate the body-mass index (BMI) of adult residents in Brazil's state capitals. Data on HA, DRB, and SSP were obtained from Brazil's SIH/SUS and AEPS Infologo systems. Pearson's correlation and linear regression models were applied. The study selected 23 diseases of the International Classification of Disease (ICDs) belonging to chapters C; E; I; and K. Cost values in BRL were deflated using IPCA.

RESULTS

The results showed a significant increase in overweight and obesity rates in Brazil, with BMI rising by 0.09 kg/m2 annually. Regression analysis revealed that each 1-point increase in the average BMI of the population is associated with an increase of 81,772 (BRL 237.51 million/year) new HA per year, 5541 (BRL 18.8 million/year) new DRB granted per year, and 42,360 (BRL 131 million/year) new SSP per year. Also, every 1 % increase in the share of the Brazilian population with obesity is associated with an increase of 16,973 (BRL 48.8 million/year) new HA per year, 1202 (BRL 3.97 million/year) new DRB granted per year, and 8686 (BRL 26.8 million/year) new SSP per year. Regressions for deflated values showed lower significance, suggesting a strong impact of inflation on health costs in Brazil.

CONCLUSIONS

Obesity prevalence in Brazil implies high direct and indirect costs for the Brazilian government, especially considering circulatory system diseases.

Steatosarcopenia: A New Terminology for Clinical Conditions Related to Body Composition Classification

Body composition analysis focuses on measuring skeletal muscle mass and total body fat. The loss of muscle function and mass is related to clinical conditions such as frailty, increased risk of falls, and prolonged hospitalizations. Despite the relevance of the definition of sarcopenic obesity, there is still a gap in the monitoring of patients who have the combination of sarcopenia and myosteatosis, regardless of the presence of obesity. Therefore, we propose a new nomenclature, steatosarcopenia, a condition characterized by the loss of mass or skeletal muscle strength and performance associated with the excessive deposition of ectopic reserve fat in muscle tissue, in the same individual, not necessarily related to excess fat total body mass. A greater understanding of this condition may assist in developing strategies for preventing and treating metabolic diseases.

Health risk factors among adult individuals with and without diabetes in Brazil: Vigitel (2020-2023)

OBJECTIVE

This study aimed to analyze the risk factors associated with diabetes mellitus (DM) among Brazilian adults.

STUDY DESIGN

Cross-sectional study.

METHODS

Data of 75,860 Brazilian adults (≥18 years) were collected using the Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel) (2020-2023). Variables assessed included self-reported medical diagnosis of DM, sociodemographic factors (sex, age, schooling, marital status) and DM risk factors (regular consumption of sweetened beverages (≥5 times/week), infrequent consumption of fruits and vegetables, and beans (<5 times/week), insufficient physical activity, prolonged screen time on cell phones, computers, tablets (CCT), and television (TV), smoking, heavy episodic drinking, excess weight, and obesity). Logistic regression models estimated crude and adjusted odds ratio (aOR) (adjusted for sociodemographic characteristics) for the association between the risk factors and the presence of DM.

RESULTS

The overall prevalence of self-reported DM in the population was 9.2%. There was a lower chance of regular consumption of sweetened beverages (aOR 0.79; 95% CI: 0.65-0.97) and heavy episodic drinking (aOR 0.77; 95% CI: 0.65-0.93) and a greater chance of insufficient physical activity (aOR 1.40; 95% CI: 1.25-1.55), prolonged TV screen time (aOR 1.22; 95% CI: 1.09-1.36), excess weight (aOR 1.62; 95% CI: 1.44-1.82) and obesity (aOR 1.87; 95% CI: 1.67-2.10) among individuals with DM.

CONCLUSION

There was a lower chance of regular consumption of sweetened beverages and heavy episodic drinking among individuals with DM and a greater chance of insufficient physical activity, prolonged TV screen time, excess weight, and obesity, among that.

Mobile solution and chronic diseases: development and implementation of a mobile application and digital platform for collecting, analyzing data, monitoring and managing health care

BACKGROUND

Technological advances based on mobile health (mHealth), the field of digital health (eHealth) aimed at managing health services and care and their concomitant transformations, have become increasingly important in the 21st century. In this context, care for individuals diagnosed with Chronic Non-Communicable Diseases (CNCDs) deserves to be highlighted. The aim of this study is to present the creation, development and implementation of the Telehealth Center of the Federal University of Viçosa (NUTELES - UFV), for the monitoring and management of health care for individuals with Arterial Hypertension (AH) and/or Diabetes Mellitus (DM).

METHODS

This study, carried out in 2022 and 2023, involved 374 patients diagnosed with AH and/or DM in the health micro-region of Viçosa/MG, Brazil, comprising nine municipalities. The research aims to describe the creation, development and implementation of a software (NutelesApp) for the collection, storage, management and analysis of epidemiological research in public health, focusing specifically, on the monitoring and management of health care for individuals with AH and/or DM monitored by Primary Health Care (PHC). The parameters collected and analyzed were obtained through a questionnaire applied to patients, consisting of 70 questions, subdivided into 12 classes of questions. The epidemiological survey data was collected using mobile devices and analyzed using computer techniques based on statistical analysis. Once the field teams had completed their work, the files were transferred to servers for general analysis processing, using estimates of means, prevalence and respective standard errors, calculated using the Statistical Package for Social Science (SPSS) program, which takes into account the planning variables and includes the basic weights resulting from the sampling process. This study was approved by the Human Research Ethics Committee and registered, prior to recruitment, by the Brazilian Registry of Clinical Trials (ReBEC), ID: RBR-45hqzmf (Last approval date: 11/30/2022).

RESULTS

The information obtained through data collection with subsequent exploratory analysis of epidemiological data using the NutelesApp software suggests that mobile applications intended for the purpose of monitoring and managing healthcare for people with AH and/or DM should address the variables necessary to support a process of understanding the health conditions and/or disease of the individual as a whole and provide short- and long-term learning. Regarding the results of the survey using the software, the variables of 374 people were analyzed. Majority are female (73.2%) and white (43.5%). Most patients are elderly (average 64 years), with blood pressure levels within the normal range for this population, BMI indicates overweight, AC increased risk for cardiovascular events and CC within the recommendation value. All biochemical parameters analyzed were above normal limits.

CONCLUSIONS

The description of the creation and development of the software includes practical examples of its implementation, the results collected and its applicability in real scenarios, presenting determining criteria that can provide assertive and timely interventions for monitoring and managing the health and/or disease parameters of patients with HA and/or DM. In addition, the beneficial consequences of using this application will extend to health units and their respective management, improving the services provided by PHC and enhancing strategies and actions for health promotion and disease prevention.

Validation of a dietary advice protocol for adults with obesity in primary health care according to the Brazilian Dietary Guidelines

BACKGROUND

Obesity is a non-communicable chronic disease which carries a high cost for the Brazilian Unified Health System. Standardized protocols can help primary health care (PHC) professionals manage the disease.

OBJECTIVES

To describe the validation process of a protocol concerning dietary guidelines for adults with obesity in PHC by non-nutrition professionals.

METHODS

A validation study of a dietary advice protocol consisting of 6 recommendations was conducted according to Brazilian Dietary Guidelines. The topics incorporated into the recommendations were submitted to a panel of judges for content validity and achieved a Scale Content Validity Index (S-CVI) score >0.80. Subsequently, an online workshop was held and consisted of guiding questions to adequately improve current protocols. Face validity was assessed in a mediation workshop conducted with PHC non-nutrition professionals. Following the validation process, necessary adjustments were made to the eating protocol.

RESULTS

The validation process was conducted by a panel of 20 judges and 10 PHC professionals. The content was validated using a 0.98 S-CVI. The online workshop expert panel agreed the instrument provides a trustworthy foundation for appropriate dietary guidelines. Moreover, the judges suggested changes to the flowchart designed to support the professionals' decisions, discussed the absence of quantitative prescription guidelines, and offered additional suggestions to strengthen equity and encourage autonomy in non-nutrition healthcare professionals in PHC.

CONCLUSION

This study describes the validation process of a dietary advice protocol for people with obesity, as well as the importance of its integration into PHC.

The Effects of Functional Training on the Ambulatory Blood Pressure and Physical Fitness of Resistant Hypertensive Elderly People: A Randomized Clinical Rehearsal with Preliminary Results

OBJECTIVE

This study evaluated the impact of functional training (FT) on the ambulatory blood pressure and physical fitness of resistant hypertensive older adults.

METHOD

This randomized clinical and controlled rehearsal involved 15 participants from Juazeiro do Norte-CE divided into two groups: a control group (CG), n = 7, without physical training, and an experimental group (EG), n = 8, subjected to 24 sessions of FT. The comparative analysis included ambulatory blood pressure (24 h mapping) and physical fitness (Senior Fitness Test), using an ANOVA of two factors, an alpha of 0.05, and a post hoc by Bonferroni where necessary. The dimension of the intervention effect was verified using Eta Squared.

RESULTS

The results show that FT promoted a significant reduction in systolic blood pressure (SAP) during the day and at night, as well as improving physical fitness, including the force/resistance of the lower and upper limbs, physical mobility, and aerobic resistance. The flexibility of the upper and lower limbs was not affected.

CONCLUSION

It is concluded that FT is effective in reducing SAP and improving physical fitness in resistant older adults. However, this type of training may positively influence general physical fitness of older adults with resistant hypertension.

Costs of obesity attributable to the consumption of sugar-sweetened beverages in Brazil

Excess sugar is considered one of the primary factors contributing to overweight status. In Brazil, sugar-sweetened beverages (SSBs) contain a significant amount of this nutrient and are consumed excessively. These beverages are associated with adverse health outcomes and impose costs on the healthcare system. The literature currently lacks studies that aim to attribute specific nutrients or foods as causes of diseases and also evaluate their economic impact, especially in middle- and low-income countries. This study aims to estimate the direct and indirect costs of obesity, stratified by sex and age group, resulting from the excessive consumption of sugar-sweetened beverages in Brazil from 2008 to 2020, and to project these costs for the year 2036. The estimation of obesity costs attributable to excessive consumption of SSBs was based on relative risks and the population prevalence of obesity, considering expenditures on hospitalizations and outpatient procedures in the Unified Health System (SUS). Cost information was obtained from the health information systems available at SUS. The highest burden attributable to the consumption of SSBs was observed among younger individuals and progressively decreased with advancing age. The total direct costs in the period between 2008 and 2020 amounted to approximately US$ 6.33 million, 87% of which was related to expenses for females. Additionally, deaths resulting from the consumption of SSBs cost the economy US$ 40 million due to the premature loss of productivity. The total costs of obesity attributable to the consumption of SSBs are substantial, impacting public spending and generating social and productivity losses that burden the economy. It is crucial to develop and implement cost-effective fiscal and regulatory policies aimed at preventing and combating obesity.

Predicting the prevalence of type 2 diabetes in Brazil: a modeling study

Aims

We adopted a modeling approach to predict the likely future prevalence of type 2 diabetes, taking into account demographic changes and trends in obesity and smoking in Brazil. We then used the model to estimate the likely future impact of different policy scenarios, such as policies to reduce obesity.

Methods

The IMPACT TYPE 2 DIABETES model uses a Markov approach to integrate population, obesity, and smoking trends to estimate future type 2 diabetes prevalence. We developed a model for the Brazilian population from 2006 to 2036. Data on the Brazilian population in relation to sex and age were collected from the Brazilian Institute of Geography and Statistics, and data on the prevalence of type 2 diabetes, obesity, and smoking were collected from the Surveillance of Risk and Protection Factors for Chronic Diseases by Telephone Survey (VIGITEL).

Results

The observed prevalence of type 2 diabetes among Brazilians aged over 25 years was 10.8% (5.2-14.3%) in 2006, increasing to 13.7% (6.9-18.4%) in 2020. Between 2006 and 2020, the observed prevalence in men increased from 11.0 to 19.1% and women from 10.6 to 21.3%. The model forecasts a dramatic rise in prevalence by 2036 (27.0% overall, 17.1% in men and 35.9% in women). However, if obesity prevalence declines by 1% per year from 2020 to 2036 (Scenario 1), the prevalence of diabetes decreases from 26.3 to 23.7, which represents approximately a 10.0% drop in 16 years. If obesity declined by 5% per year in 16 years as an optimistic target (Scenario 2), the prevalence of diabetes decreased from 26.3 to 21.2, representing a 19.4% drop in diabetes prevalence.

Conclusion

The model predicts an increase in the prevalence of type 2 diabetes in Brazil. Even with ambitious targets to reduce obesity prevalence, type 2 diabetes in Brazil will continue to have a large impact on Brazilian public health.

Trend in the Prevalence of Overweight and Obese Adults in São Paulo, Brazil: Analysis between the Years 2006 and 2019

The aim of this study was to investigate the trend in the prevalence of overweight and obese adults in São Paulo, Brazil, between 2006 and 2019 across chronic diseases and the domains of physical activity. A descriptive retrospective study was carried out on the trend in the prevalence of 26.612 overweight and obese adults (10.150 men and 16.462 women). All data analyzed were based on information from the national system for monitoring risk factors called Protective and Risk Factors for Chronic Diseases by Telephone Survey-VIGITEL. The variables obese and overweight were analyzed in general and stratified by sex, age group, education level, each type of physical activity domain (yes or no), presence of hypertension and diabetes (yes or no), and smoking (yes or no). The prevalence of obesity significantly increased from 11.1% in 2006 to 19.8% in 2019, regardless of age, sex, physical activity practice, and presence of diabetes or hypertension, except for people aged 55-64 y, working people, and smokers. The total prevalence of overweight adults significantly increased overall (from 30.5% in 2006 to 33.4% in 2019) but it significantly increased only in females, in people aged 18-24 y, those who are non-white, those with an education level of 9-11 y, those who are not working, those who are non-smokers, those who did not have diabetes or hypertension, and those who were not physically active during leisure time but physically active at work and at home. There was a significant increase in the prevalence of overweight adults and especially of obese adults living in the city of São Paulo (Brazil) between 2006 and 2019, the latter being observed in nearly every analyzed sub-category, regardless of age, sex, physical activity practice, and presence of diabetes or hypertension.

The association between BMI and self-reported health among a Brazilian sample: a cross-sectional study

OBJECTIVE

To examine the association between Body Mass Index (BMI) and self-rated health status among a representative sample of the Brazilian population.

METHODS

This study consists of a secondary analysis of the existing 2019 Brazilian National Health Survey (PNS). Logistic regression models were then used to examine the association between self-reported health status and BMI, while controlling for obesity-related medical conditions and socio-demographic characteristics.

RESULTS

The representative sample included 34,021 men and 34,430 women, comprising a total sample of 68,451. Men living with obesity (BMI ≥ 30 kg/m2) had, on average, a lower self-reported health status score (OR = 0.69, p < 0.01) compared to men within a healthy weight BMI range (18.5-25 kg/m2). Women living with obesity had, on average, a lower self-reported health status score (OR = 0.56, p < 0.01) compared to women within a healthy weight BMI range (18.5-25 kg/m2). There was also a statistically significant negative association (p < 0.01) between our obesity-related medical conditions and self-reported health for men and women. We also find some evidence of a non-linear association between BMI and health status for men.

CONCLUSIONS

The findings indicate that there is a statistically significant negative association between BMI and self-reported health for Brazilian men and women living with obesity. These findings reinforce the importance of addressing this growing public health challenge and the value of preventive measures and effective public health programs that focus on improving overall health and quality of life for individuals living with obesity.

Economic burden for the Unified Health System attributable to excessive sodium consumption in Brazil

OBJECTIVES

This study aimed to estimate the economic costs of excessive sodium consumption in terms of hospitalizations and outpatient procedures of medium and high complexity (OPMHC) for the Brazilian Unified Health System (SUS) and its states in 2019.

STUDY DESIGN

Ecological study.

METHOD

This study used population attributable fractions (PAFs) of excessive sodium consumption estimated by the Global Burden of Disease study based on the theoretical minimum risk exposure level (3 g of sodium per day), the average population consumption, and relative risks of sodium-outcome pairs. PAFs were applied to the total costs of hospitalizations and OPMHC paid by SUS for each outcome obtained from the Outpatient and Hospital Information Systems. The costs per 10,000 inhabitants in all the Brazilian states were calculated and converted into international dollars (Int$), considering the purchasing parity power in the year 2019.

RESULTS

Excessive sodium consumption resulted in Int$ 98,882,386.36 (95% uncertainty interval: Int$ 3,398,343.53-312,065,319.80) in hospitalizations and OPMHC costs in Brazil in 2019. Males and the 55- to 69-year-old age group had the highest expenditures attributable to excessive sodium consumption. Cardiovascular diseases were the most significant contributors to the costs associated with the risk factor. Southern and southeastern states had the highest costs of diseases attributable to sodium.

CONCLUSION

Excessive sodium consumption has a significant economic burden on SUS, particularly among men and more developed states. This underscores the inequalities in socio-economic factors and access to health services throughout the country. Economic analyses at the subnational level can provide evidence for public policy planning to define the most appropriate actions for the population's sociodemographic reality.

Analysis of the elaboration and proposal of a Brazilian intersectoral strategy for the prevention and care of childhood obesity

The Brazilian Strategy for the Prevention and Care of Childhood Obesity (PROTEJA) aims to implement a set of actions to prevent obesity in Brazil. As such, this qualitative and descriptive documentary study presents the Strategy's stages of the operational design, general proposal, evaluation and monitoring conducted by the Brazilian Ministry of Health's technical coordination. After analyzing the epidemiological data on children and the existing policies aimed at obesity prevention, and reviewing the scientific literature and recommendations, PROTEJA was formulated and approved by the Brazilian Ministry of Health, and 1,320 municipalities committed to implementing 20 essential and 5 complementary actions, from 41, including some structural to improve environments. Coordinated by the Brazilian Ministry of Health in partnership with subnational governments and universities, the Strategy also relies on a local team for implementation support, as well as implementation and impact evaluations. Actions will be monitored annually, and the indicators will impact financial incentives. As a strong, evidence-based and innovative strategy aiming to promote healthy environments in cities, PROTEJA has the potential to open a path to childhood obesity reversal, as well as add to the implementation science and contribute to the development and improvement of public policies for obesity prevention; however, its implementation remains a challenge.

Accuracy of wearable electronic device compared to manual and automatic methods of blood pressure determination

Blood pressure (BP) is the main biomarker for monitoring patients, as its lack of control above values considered normal is a modifiable risk factor for target organ damage. The aim of this study is to evaluate the accuracy of the wearable electronic device photoplethysmography technology (PPG) Samsung Galaxy Watch 4 in determining BP in young patients compared to manual and automatic methods of BP determination. This is a quantitative and cross-sectional study, following validation protocols for wearable devices and BP measurement. It was carried out with twenty healthy young adults, in which BP was measured using four instruments, namely, standard sphygmomanometer device (manual), automatic arm oscillometric device (reference), wrist oscillometric device, and Smartwatch PPG. Eighty systolic blood pressure (SBP) and diastolic blood pressure (DBP) readings were observed. SBP means manual 118 ± 2.20,arm 113 ± 2.54, wrist 118 ± 2.51, and PPG (smartwatch) 113 ± 2.58. Among means, arm and PPG difference is 0.15, arm and wrist 4.95, arm and manual 4.45 wrist with PPG. The mean DBP manual 76.7 ± 1.84, arm 73.6 ± 1.92, wrist 79.3 ± 1.87, and PPG 72.2 ± 1.38. Among means, the difference between the arm and PPG is 1.4 and arm and hand 3.5 mmHg. The correlation shows PPG with manual, arm, and wrist. There was a strong SBP correlation and a moderate DBP correlation between the methods tested, evidencing the accuracy of the PPG smartwatch in relation to the reference method.

Animated Videos Based on Food Processing for Guidance of Brazilian Adults: Validation Study

BACKGROUND

Ultraprocessed foods (UPFs) contribute almost one-fifth of the calories consumed by the Brazilian population. This consumption has been favored by aspects such as the ease of acquisition and low cost of this food group. Initiatives focused on supporting and promoting healthy eating practices have been implemented. Among them, the availability of educational resources is an important strategy to maximize the effectiveness of these actions in the field of food and nutrition education (FNE).

OBJECTIVE

This study aims to describe the development and validation process of animated videos based on the NOVA food classification for FNE actions aimed at Brazilian adults.

METHODS

This methodological study was developed in the following 4 phases: planning, preproduction, production, and postproduction. In the planning phase, a literature review was con-ducted on the topic and to define the content to be covered. The design of the material was based on the cognitive theory of multimedia learning. In the preproduction phase, video scripts were developed and evaluated by 7 content specialists. In the production phase, videos were developed based on the assessed scripts and then assessed by 3 multimedia production specialists. In the postproduction phase, the videos were evaluated by 15 representatives of the target audience. All results obtained in the evaluation phases were analyzed using the content validity index (CVI).

RESULTS

We developed 3 animated videos covering the following themes: food processing levels, food categories according to processing levels, and UPFs and their impact on health. In the evaluation by the content specialists, the scripts of videos 1, 2, and 3 obtained CVIs at the scale level and average method equal to 0.96, 0.98, and 0.98, respectively. When the animated videos were evaluated by multimedia production specialists and representatives of the target audience, these indexes were equal to 1.0. These results attest to the videos' adequacy and quality in communicating the addressed content.

CONCLUSIONS

The animated videos developed and validated in this study proved to be adequate for their purpose. Thus, it is expected that they will be an important instrument for FNE actions aimed at an adult audience and for disseminating the Dietary Guidelines for the Brazilian Population.

An Analysis of Key Actor Networks for Scale-Up Strategies for Childhood Obesity Prevention and the Care of Children with Obesity in Brazil

Background

Effective scale-up of multisectoral strategies aimed to prevent and treat childhood obesity has been a challenge in Brazil, the largest country in Latin America. Implementation Science methods, such as Net-Map, can identify key actors and opinion leaders (OLs) to advance the implementation and promote sustainability.

Objectives

This study aimed to analyze power relations between key actors and OLs who influence the scale-up of Brazilian strategies for childhood obesity at the federal and state/municipal (local) levels.

Methods

A mixed method study, applying the Net-Map method, collected data through virtual workshops with federal and local level stakeholders. The Net-Map included key actors mapping, power mapping, and identification of OLs. Four domains of power were analyzed: command, funding, technical assistance, and dissemination. Network cohesion and centrality measures were calculated. A qualitative analysis was conducted to qualify power relations according to ∗ gears for a successful scale-up (i.e., coordination, goals, and monitoring; advocacy; political will; legislation and policy; funding and resources; training; program delivery; communication; and research and technical cooperation).

Results

A total of 121 federal key actors and 63 local key actors were identified across networks, of which 62 and 28 were identified as OLs, respectively. Whereas the command domain of power had the highest number of key actors, the funding domain had the least. The health sector executive branch emerged as an OL across all domains of power.

Conclusions

Barriers that threatened successful scale-up include the lack of coordination between domains of power, missing leadership within key actors, and lack of mechanisms to manage conflict of interest. Governance strategies to enhance multisectoral coordination and communication are needed to effectively scale-up and sustain childhood obesity strategies in Brazil.

Clinical Characteristics and Outcomes among Vaccinated and Unvaccinated Patients with Cardiovascular Disease Who Were Hospitalized for COVID-19 in Brazil: Retrospective Cohort

INTRODUCTION

COVID-19 in Brazil has already caused, and it still causes, several impacts on health, economy, and education. The risk factors for death involved those with cardiovascular diseases (CVD), which were prioritized for the vaccination of COVID-19.

OBJECTIVE

To investigate the clinical characteristics and outcomes between vaccinated and unvaccinated patients with cardiovascular diseases hospitalized for COVID-19 in Brazil in the year 2022.

METHODS

A retrospective cohort was analyzed from the year 2022, with cases being hospitalized by COVID-19 being drawn from SIVEP-GRIPE surveillance. We compared clinical characteristics, comorbidities, and outcomes between CVD carriers and non-carriers, and we also compared vaccinated with two doses vs. those that are unvaccinated in CVD carriers. We performed chi-square, odds ratio, logistic regression, and survival analysis.

RESULTS

We included, in the cohort, 112,459 hospital inpatients. An amount of 71,661 (63.72%) of the hospitalized patients had CVD. Regarding deaths, 37,888 (33.69%) died. Regarding vaccination against COVID-19, 20,855 (18.54%) people were not vaccinated with any dose among those with CVD. Death p- < 0.001 (OR 1.307-CI 1.235-1.383) and fever p- < 0.001 (OR 1.156-CI 1.098-1.218) were associated with the unvaccinated CVD carriers, and diarrhea p-0.015 (OR 1.116-CI 1.022-1.218), dyspnea p-0.022 (OR 1.074-CI 1.011-1.142), and respiratory distress p-0.021 (OR 1.070-CI 1.011-1.134) were also recorded. Those patients who possessed predictors of death, including invasive ventilation (p- < 0.001 (OR 8.816-CI 8.313-9.350)), were admitted to the ICU p- < 0.001 (OR 1.754-CI 1.684-1.827), and some had respiratory distress p- < 0.001 (OR 1.367-CI 1.312-1.423), dyspnea p < 0.001 (OR 1.341-CI 1.284-1.400), O₂ saturation < 95% p- < 0. 001 (OR 1.307-CI 1.254-1.363), they were unvaccinated against COVID-19 p- < 0.001 (OR 1.258-CI 1.200-1.319), they were of male sex p- < 0.001 (OR 1.179-CI 1.138-1.221), they had diarrhea p-0.018 (OR 1.081-CI 1.013-1.154), and they may have been old p < 0.001 (OR 1.034-CI 1.033-1.035). Survival was shorter for the unvaccinated p-0.003, and p- <0.001.

CONCLUSIONS

We highlight the predictors of death for those unvaccinated against COVID-19 in this research, and we evidenced the benefits of the COVID-19 vaccine in reducing deaths in hospitalized CVD patients.

Effects of neuromodulation on executive functions and food desires in individuals with obesity: a systematic review

Introduction

Objective: to describe the effects of neuromodulation on the performance of executive functions in overweight and/or individuals with obesity. Methods: articles published in PubMed, ScienceDirect, BIREME, and Web of Science databases were selected using the following combination of descriptors: ("problem solving" OR "executive function" OR memory) AND (tDCS OR TMS) AND obesity. After applying the selection criteria, 08 articles were included for analysis. Results: the articles included had an average of 30.1 participants per study, with a minimum of 12 and a maximum of 76. The overall nutritional status ranged from underweight to grade 3 obesity, and the general mean body mass index was 28,1 kg/m2. Regarding the instruments used to assess executive functions, the most frequent were: the flanker paradigm; binocular rivalry for Continuous Flash Suppression (bCFS/NoCFS); Stroop task; Go/No-Go task; and N-back task. The primary outcomes were dependent on the neuromodulation target site. Reduced food craving and improved performance in the active group were observed from decreased response time and increased precision in cognitive tasks. Conclusion: neuromodulation can generate changes in executive functions, reducing food cravings in overweight and individuals with obesity.

Methodological aspects and characteristics of participants in the study on the prevalence of obesity in children and adolescents in Florianópolis, Southern Brazil, 2018-2019: EPOCA study

PURPOSE

To describe the methodological aspects and characteristics of the participants of the EPOCA survey.

METHODS

The study was conducted with schoolchildren aged between seven to 14 years old from 30 schools in Florianópolis, Southern Brazil. Body mass, height, girths, and skinfold thicknesses were measured. Food consumption and physical activity from the previous day were self-reported using the validated Web-CAAFE questionnaire. Adolescents completed a specific questionnaire about physical activity, meal consumption, and weight control behaviors. Parents/guardians responded to a sociodemographic and habits questionnaire.

RESULTS

A total of 1671 schoolchildren participated in the study (response rate: 27.2%). About 63% of schoolchildren were enrolled in public schools. Most studied in the morning shift (54.2%), were female (53.1%) and aged between seven and 10 years (58.1%). The prevalence of overweight was 33.7% and obesity was 11.3%.

CONCLUSIONS

The data obtained will allow us to assess the trend in the prevalence of overweight and obesity and associated factors when compared to other surveys performed. Descriptions of the logistics and protocols can help in the development and improvement of similar studies. It is hoped that the results of EPOCA 2018/2019 may help in the design of obesity prevention policies and programs for this population.

Content validation of a questionnaire to assess the knowledge of pediatricians, family, and community physicians on obesity

OBJECTIVE

The aim of this study was to validate the content of a questionnaire in order to assess the attitudes and practices in childcare consultations, knowledge on overweight and obesity, their risk factors, and barriers in addressing the issue by pediatricians and family physicians.

METHODS

The Delphi technique was used, with the objective of reaching a consensus on a certain subject, through experts' opinions. The content validity index (CVI) of each item, axis, and questionnaire was calculated. The inter-rater reliability was calculated using an agreement coefficient suitable for the answer distribution such as Gwet's AC2 with ordinal weight.

RESULTS

A total of 63 experts were invited to assess and give their opinion on the questionnaire. In all, 52 accepted the invitation and analyzed the instrument. After two rounds, the questionnaire reached the proper CVI for the study and was considered complete, with its final version having 40 questions, a final index of 95%, and an inter-rate reliability of 0.905.

CONCLUSIONS

This instrument, developed to assess attitudes and practices, knowledge, and barriers found in addressing the obesity by primary care physicians, obtained a CVI greater than 0.8 and an excellent agreement coefficient of the 52 judges. Therefore, its content can be considered validated.

Health economic impacts associated with the consumption of sugar-sweetened beverages in Brazil

Introduction

The consumption of sugar-sweetened beverages (SSBs) is among the main risk factors for non-communicable diseases (NCDs). This study aimed to estimate the financial costs of hospitalizations and procedures of high and medium complexity for NCDs attributable to the consumption of SSBs in the Brazilian Unified Health System (SUS) in 2019.

Methods

This ecological study used data from the Global Burden of Disease (GBD) 2019 and the Department of Informatics of the Unified Health System (DATASUS). The attributable costs were estimated from the population-attributable fraction (PAF) and the costs in the treatment of chronic diseases [type 2 diabetes mellitus and ischemic heart disease (IHD)], stratified by sex, age group, level of complexity of treatment, and federative units.

Results

In 2019, in Brazil, US$ 14,116,240.55 were the costs of hospitalizations and procedures of high and medium complexity in the treatment of NCDs attributable to the consumption of SSBs. These values were higher in males (US$ 8,469,265.14) and the southeast and southern regions, mainly in the state of São Paulo. However, when evaluating these results at a rate per 10,000 inhabitants, it was observed that the states of Paraná, Tocantins, and Roraima had higher costs per 10,000 inhabitants. Regarding the age groups, higher costs were observed in the older age groups.

Conclusion

This study revealed the high financial impact of the NCDs treatment attributed to the consumption of SSBs in Brazil and the variability among Brazilian macro-regions. The results demonstrate the urgency and need for the expansion of policies to reduce the consumption of SSBs in Brazil with strategies that consider regional particularities.

Effects of the association of different volumes of strength training with photobiomodulation therapy on insulin resistance: A protocol for a randomized, triple-blind, placebo-controlled trial

Background

Insulin resistance (IR) is the main risk factor for developing type 2 diabetes. Both strength training (ST) and photobiomodulation therapy (PBMt) reduce IR, but the effect of combining different volumes of ST with PBMt is unknown.

Methods

Overweight/obese individuals will be assigned to 4 groups (n = 12/group): ST with volume following international guidelines (3 sets per exercise - high volume) or one-third of this volume (1 set per exercise - low volume), combined with PBMt or placebo. ST will be performed for 20 sessions over 10 weeks and will consist of 7 exercises. The PBMt will be applied after training sessions using blankets with light emitters (LEDs) placed over the skin on the frontal and the posterior region of the body, following the parameters recommended by the literature. The placebo group will undergo an identical procedure, but blankets will emit insignificant light. To measure plasma glucose and insulin concentrations, oral glucose tolerance tests (OGTT) will be performed before and after the training period. Thereafter, IR, the area under the curve of glucose and insulin, and OGTT-derived indices of insulin sensitivity/resistance will be calculated.

Expected impact on the field

This study will determine the effects of different ST volumes on IR and whether the addition of PBMt potentiates the effects of ST. Because previously sedentary, obese, insulin-resistant individuals might not comply with recommended volumes of exercise, the possibility that adding PBMt to low-volume ST enhances ST effects on IR bears practical significance.

Self-reported arterial hypertension, use of health services and guidelines for care in Brazilian population: National Health Survey, 2019

OBJECTIVE

To describe the prevalence of arterial hypertension according to sociodemographic characteristics in Brazil and to analyze the indicators related to access to health services and guidelines for controlling the disease in the country.

METHODS

Cross-sectional descriptive study using the National Health Survey (PNS) conducted in 2019. The prevalence of hypertension was estimated with a 95% confidence interval, in addition to the proportions of hypertension indicators.

RESULTS

There were 88,531 respondents, of which 23.9% self-reported hypertension, more prevalent among females (26.4%) and the elderly (55.0%). Among those who self-reported hypertension, 57.8% reported medical attention in the last six months; most received guidance on self-care; 66.1% were seen in public health services; and 45.8%, in primary health care units.

CONCLUSION

The prevalence of hypertension in the Brazilian population was high, with most people who self-reported the condition being seen in services of the Brazilian National Health System (SUS), where they received guidance on health promotion.

Obesity and health service utilization in Brazil: data from the National Health Survey

BACKGROUND

Obesity, a complex public health problem, is generally associated with other chronic diseases. The association of obesity with health service utilization has been little investigated in low- and middle-income countries. This study aimed to analyze the association between obesity and health service utilization (considering those services related to hypertension and/or diabetes).

METHODS

A cross-sectional, nationally-representative, study of Brazilians aged ≥18 years was conducted. Data from the National Health Survey (2013) for 59,402 individuals were analyzed, including measured weight and height. The association between body mass index (BMI) category (under/normal weight, overweight, and obesity) and health service utilization due to hypertension and/or diabetes was investigated using Poisson regression models (crude and adjusted). To analyze the health services utilization, the following variables were considered: 1) routine visits to a general doctor or health service; 2) referrals/consultations with a specialist; 3) prescribed exams done; and 4) hospital admission due to the disease or related complication. All analyses were stratified by sex.

RESULTS

Compared with under/normal-weight individuals, subjects with obesity (both male and female) made roughly double the use of all health care services assessed. Men with hypertension that had obesity had a higher risk of hospital admission (adjusted PR = 2.55; 95%CI 1.81-3.61), than those with under/normal weight. Women with diabetes that had obesity had more referrals/consultations with specialists (adjusted PR = 2.56; 95%CI 1.94-3.38), than those with under/normal weight.

CONCLUSIONS

The presence of obesity was associated with increased use of health care services for hypertension and/or diabetes, indicating greater demand for human resources and materials, and a greater burden on the national health system.

Consumo de alimentos açucarados e qualidade do sono no primeiro ano de vida

Objetivo: investigar a duração do sono (DS), a frequência de despertares noturnos (DN) e o consumo de alimentos açucarados no primeiro ano de vida e verificar a associação entre o consumo desses alimentos e a má qualidade do sono. Métodos: a população do estudo foi composta de 179 crianças integrantes de uma coorte de nascimentos de Rio Largo-AL. As mães foram questionadas sobre a oferta regular de alimentos açucarados (açúcar/farinhas de cereais instantâneas com açúcar/bebidas açucaradas/doces) e o sono foi investigado pelo questionário traduzido e validado Brief Infant Sleep Questionnaire. Foram considerados indicadores de má qualidade do sono DS<12h e DN>2. Os testes de qui-quadrado de Pearson e exato de Fisher foram adotados para verificar associações entre o consumo de açucarados e a má qualidade do sono aos seis e 12 meses (p<0,05). Resultados: mais da metade das crianças apresentou DS<1 2h (60,3%) e cerca de ¼ DN>2. O consumo regular de pelo menos uma das categorias de açucarados foi verificado entre 50,6, 91,1 e 100% das crianças aos três, seis e 12 meses de idade, respectivamente. Não foram encontradas associações entre o consumo desses alimentos e os indicadores de má qualidade de sono. Conclusão: o consumo de açucarados e a má qualidade de sono foram frequentes em nosso estudo, no entanto, não se identificou associação entre as variáveis. Mais investigações são necessárias para elucidar como o sono e a alimentação se inter-relacionam e se potencializam mutuamente como fatores determinantes do crescimento e desenvolvimento de lactentes.

Factors Associated with Overweight and Obesity in Adults from Rio Branco, Acre in the Western Brazilian Amazon

This study aimed to assess factors associated with overweight and obesity in adults from Rio Branco, Acre, in the western Brazilian Amazon. This is a cross-sectional, population-based study conducted in Rio Branco, which used data on individuals aged 18 years or older collected by the 2019 National Health Survey. Software R version 4.0.5 was used to estimate the prevalence of overweight and obesity, prevalence ratios, and 95% confidence intervals. Multiple analysis was performed by Poisson's regression with robust variance and hierarchical selection of variables. This study included 1217 adults. The prevalence of overweight was 58.2% (95%CI: 54.7-61.6) and of obesity, 20.1% (95%CI: 17.2-23.4). The factors associated with overweight were arterial hypertension (AdjPR: 1.45; 95%CI: 1.31-1.61), physical inactivity (AdjPR: 1.19; 95%CI: 1.04-1.36), age group (25-39 years, AdjPR: 1.49; 95%CI: 1.10-2.00; 40-59 years, AdjPR: 1.69; 95%CI: 1.28-2.23; 60 years or older, AdjPR: 1.37; 95%CI: 1.01-1.87); and smoking (AdjPR: 0.62; 95%CI: 0.41-0.93). The factors associated with obesity were arterial hypertension (AdjPR: 1.80; 95%CI: 1.41-2.30) and diabetes mellitus (AdjPR: 1.52; 95%CI: 1.08-2.13). Smoking and female sex remained in the hierarchical model for obesity, even without statistical significance. Despite intervention guidelines for these chronic diseases, there is a need for the public recognition of overweight and obesity and their possible associated factors in the Amazon and other regions with similar socioeconomic and demographic characteristics.

Risk factors associated with hypertension among inmates in southern Brazil

Objective: To identify the association between risk factors for systemic arterial hypertension and blood pressure levels in prisoners under a closed regime. Materials and methods: Cross-sectional study conducted with prisoners under a closed regime between February and September 2019. A total of 240 men from a penitentiary complex in southern Brazil participated in the study. A semi-structured instrument based on the national guidelines for cardiovascular diseases was used for data collection. Results: Univariate analysis allowed us to identify that physical exercise was negatively associated with the development of systemic arterial hypertension (p = 0.034). However, body mass index and abdominal circumference were positively associated with cardiovascular risk and systemic arterial hypertension (p = 0.000). Through multivariate analysis, we noted the statistical significance of the body mass index when controlled for all other variables in the model (adjusted OR = 2.33). Conclusions: Risk factors for the development of systemic arterial hypertension are present in the prison environment to a similar degree as in the general population; particularly the absence ofphysical exercise and altered body mass index and abdominal circumference. It is worth mentioning that the body mass index was the variable of greater statistical significance, since, when altered, it increased 2.33 times the chance of inmates to develop systemic arterial hypertension.

How much can sodium chloride be substituted for potassium chloride without affecting the sensory acceptance of cracker-type biscuits?

Excessive sodium consumption is a worldwide public health concern. The substitution of sodium chloride (NaCl) for potassium chloride (KCl) has been adopted to reduce the sodium concentration in processed foods. The challenge is to make this substitution without affecting the sensory acceptance of foods. In this context, the objective was to determine from which concentrations the replacement of NaCl by KCl results in reduced acceptance (compromised acceptance threshold - CAT) and begins the sensory rejection (hedonic rejection threshold - HRT) of cracker-type biscuits. Using the hedonic thresholds methodology (HTM) by varying a stimulus, CAT and HRT were determined for the concentration of NaCl in crackers and, by varying two stimuli, CAT and HRT, for replacing NaCl with KCl in crackers were determined. Without the addition of KCl, the reduction in acceptance started to occur by reducing the NaCl content by around 60% (from 1.81% to 0.73%); and sensory rejection began to appear by reducing the NaCl content by approximately 93% (1.81% to 0.13%). Reduction in the acceptance started to occur by lowering the NaCl content by around 78% (from 1.81% to 0.397%), with the addition of 0.896% KCl. In addition, by adding KCl, it was possible to reduce 100% NaCl without sensory rejection of the crackers. With these results, cracker industries can reduce the sodium content of their products, contributing to the reduction of population salt intake.

Estimating the health and economic effects of the voluntary sodium reduction targets in Brazil: microsimulation analysis

BACKGROUND

Excessive sodium consumption is one of the leading dietary risk factors for non-communicable diseases, including cardiovascular disease (CVD), mediated by high blood pressure. Brazil has implemented voluntary sodium reduction targets with food industries since 2011. This study aimed to analyse the potential health and economic impact of these sodium reduction targets in Brazil from 2013 to 2032.

METHODS

We developed a microsimulation of a close-to-reality synthetic population (IMPACTNCD-BR) to evaluate the potential health benefits of setting voluntary upper limits for sodium content as part of the Brazilian government strategy. The model estimates CVD deaths and cases prevented or postponed, and disease treatment costs. Model inputs were informed by the 2013 National Health Survey, the 2008-2009 Household Budget Survey, and high-quality meta-analyses, assuming that all individuals were exposed to the policy proportionally to their sodium intake from processed food. Costs included costs of the National Health System on CVD treatment and informal care costs. The primary outcome measures of the model are cardiovascular disease cases and deaths prevented or postponed over 20 years (2013-2032), stratified by age and sex.

RESULTS

The study found that the application of the Brazilian voluntary sodium targets for packaged foods between 2013 and 2032 could prevent or postpone approximately 110,000 CVD cases (95% uncertainty intervals (UI): 28,000 to 260,000) among men and 70,000 cases among women (95% UI: 16,000 to 170,000), and also prevent or postpone approximately 2600 CVD deaths (95% UI: - 1000 to 11,000), 55% in men. The policy could also produce a net cost saving of approximately US$ 220 million (95% UI: US$ 54 to 520 million) in medical costs to the Brazilian National Health System for the treatment of CHD and stroke and save approximately US$ 71 million (95% UI: US$ 17 to170 million) in informal costs.

CONCLUSION

Brazilian voluntary sodium targets could generate substantial health and economic impacts. The reduction in sodium intake that was likely achieved from the voluntary targets indicates that sodium reduction in Brazil must go further and faster to achieve the national and World Health Organization goals for sodium intake.

Direct cost of systemic arterial hypertension and its complications in the circulatory system from the perspective of the Brazilian public health system in 2019

INTRODUCTION

Systemic arterial hypertension (SAH), a global public health problem and the primary risk factor for cardiovascular diseases, has a significant financial impact on health systems. In Brazil, the prevalence of SAH is 23.7%, which caused 203,000 deaths and 3.9 million DALYs in 2015.

OBJECTIVE

To estimate the cost of SAH and circulatory system diseases attributable to SAH from the perspective of the Brazilian public health system in 2019.

METHODS

A prevalence-based cost-of-illness was conducted using a top-down approach. The population attributable risk (PAR) was used to estimate the proportion of circulatory system diseases attributable to SAH. The direct medical costs were obtained from official Ministry of Health of Brazil records and literature parameters, including the three levels of care (primary, secondary, and tertiary). Deterministic univariate analyses were also conducted.

RESULTS

The total cost of SAH and the proportion of circulatory system diseases attributable to SAH was Int$ 581,135,374.73, varying between Int$ 501,553,022.21 and Int$ 776,183,338.06. In terms only of SAH costs at all healthcare levels (Int$ 493,776,445.89), 97.3% were incurred in primary care, especially for antihypertensive drugs provided free of charge by the Brazilian public health system (Int$ 363,888,540.14). Stroke accounted for the highest cost attributable to SAH and the third highest PAR, representing 47% of the total cost of circulatory diseases attributable to SAH. Prevalence was the parameter that most affected sensitivity analyses, accounting for 36% of all the cost variation.

CONCLUSION

Our results show that the main Brazilian strategy to combat SAH was implemented in primary care, namely access to free antihypertensive drugs and multiprofessional teams, acting jointly to promote care and prevent and control SAH.

Plant terpenes on treating cardiovascular and metabolic disease: a review

The use of medicinal plants as a therapy alternative is old as human existence itself. Nowadays, the search for effective molecules for chronic diseases treatments has increased. The cardiometabolic disorders still the main cause of death worldwide and plants may offer potential pharmacological innovative approaches to treat and prevent diseases. In the range of plant molecules are inserted the terpenes, which constituent essential elements with several pharmacological characteristics and applications, including cardiovascular and metabolic properties. Thus, the aim of the present review is to update the terpenes use on chronic disorders such as obesity, diabetes, hypertension and vascular conditions. The review includes a brief terpenes description based on the scientific literature in addition to data collected from secondary sources such as books and conference proceedings. We concluded that terpenes could act as adjuvant or main alternative treatment (when started earlier) to improve cardiometabolic diseases, contributing to reduce side effects of conventional drugs, in addition to preserving ethnopharmacological knowledge.

Obesity is associated with lack of access to dental care and physical activity among older adults: a cross-sectional study

OBJECTIVE: This study evaluated the prevalence of obesity and associated factors among older adults. METHODS: This was a household-based cross-sectional study involving 282 individuals aged ≥ 60 years recruited in the city of Veranópolis, Brazil, using random probabilistic sampling. Participants underwent a clinical oral examination and completed a structured questionnaire. Obesity was determined based on body mass index (BMI). Individuals were divided into two groups based on the presence (BMI ≥ 30 kg/m2) or absence of obesity (BMI < 30 kg/m2). Uni- and multivariate analyses were performed using Poisson regression with robust variance. RESULTS: The prevalence of obesity was 34% (n = 96). Each 1-year increase in age resulted in a 3.09% decrease in the likelihood of being classified as having obesity (prevalence ratio [PR] = 0.969; 95% confidence interval [95%CI] 0.949 – 0.989). Older adults that reported walking < 5 or ≥ 5 times per week were 39.65 and 37.20% less likely to be classified as obese. The PRs of obesity in former and non-smokers were 4.40 and 5 times higher, respectively, than in current smokers (p < 0.05). Older adults with no access to dental care were 51.72% (p = 0.013) more likely to present with obesity. CONCLUSIONS: There was a high prevalence of obesity among older adults. Obesity was associated with lower age, smoking status, no access to dental care, and a lack of physical activity.
