This study aimed to present the content validity and reliability analyses of an instrument to study the determinant factors r;f salt consumption among hypertensive subjects, based on an extension of the Theory of Planned Behavior. Content validity was assessed by 3 experts and a pre-test was carried out with 5 sUbjects. The final tool, comprising 3 different behaviors related to salt consumption and corresponding psychosocial variables, was applied to 32 subjects for internal consistency and temporal stability (15-day interval) analysis. Cronbach's alpha coefficients > 0.70 and significant intra-class correlation coefficients were observed for most variables, indicating the temporal stability of the measured concepts. The developed instrument exhibited evidence of both content validity and reliability. [ABSTRACT FROM AUTHOR]

Background: Ambivalence towards food and diet, which favours behavioural inertia, might be a barrier to adopting healthier eating behaviours. Measuring it can help researchers to better understand its relationship with behaviour change and design interventions aimed at resolving it. In this scoping review, we map and describe methods and tools employed in studies to assess, measure or classify the ambivalence of participants towards food- and diet-related attitude objects., Methods: In accordance with Joanna Briggs Institute guidance for conducting scoping reviews, we retrieved peer-reviewed studies from MEDLINE, CINAHL, PsycINFO, Web of Science, FSTA and Food Science Source and preprints from PsyArXiv and MedRxiv. Two independent reviewers screened the articles. We considered for inclusion peer-reviewed studies and preprints that assessed the ambivalence of participants of any age, sex or sociodemographic group towards food and diet., Results: We included 45 studies published between 1992 and 2022, which included participants from 17 countries. Eighteen methods were employed across the included studies to assess different types of ambivalence (felt, potential or cognitive-affective), the most frequent of which were the Griffin Index, the Subjective Ambivalence Questionnaire, the MouseTracker Paradigm and the Orientation to Chocolate Questionnaire., Conclusion: This scoping review identified several methods and tools to assess different types of ambivalence towards food- and diet-related objects, providing an array of options for future studies., (© 2023 British Dietetic Association.)

Background: There is sound evidence associating high salt intake and a greater risk of cardiovascular and noncardiovascular diseases. High salt intake has been observed in several populations worldwide. Therefore, promoting healthier salt consumption has been encouraged as a low-cost strategy to reduce this risk factor. However, these strategies need to be sound, built on theoretical and methodological bases, and consider the target population's context., Objective: This protocol aims to describe a mobile phone app intervention to promote healthy salt intake among adults., Methods: This is an experimental and longitudinal study protocol conducted in three modules. Module 1 refers to the planning of the intervention based on the Behaviour Change Wheel framework. Module 2 is the development of the mobile phone app intervention based on the date of module 1. In module 3, the intervention will be evaluated using a randomized controlled study, with three steps of data collection in a 2-month follow-up in a sample of 86 adults (43 participants for each group: the control group and intervention group) recruited from the primary health care centers of a Brazilian town. The discretionary salt intake questionnaire will assess salt consumption, the app usability will be assessed using the System Usability Scale, and psychosocial variables (habit, intention, and self-efficacy) will also be measured., Results: Recruitment began in October 2021, and the follow-up will end in August 2022. The results of this study are expected to be published in 2023., Conclusions: Results from this study will help people to control salt intake when cooking at home, will stimulate self-care, will work as an alternative or supportive method in the relationship between health care professionals and patients, and will contribute to implementing the app intervention to promote healthy salt intake on a large scale., Trial Registration: The Brazilian Clinical Trials Registry RBR-4s8qyyq; https://ensaiosclinicos.gov.br/rg/RBR-4s8qyyq., International Registered Report Identifier (irrid): DERR1-10.2196/37853., (©Milena Sia Perin, Thais São-João, Maria Cecília Bueno Jayme Gallani, Titilayo Tatiana Agbadje, Roberta Cunha Matheus Rodrigues, Marilia Estevam Cornélio.

Objectives: To verify the content validity of questions of an insulin adherence questionnaire based on the Theory Planned Behavior in outpatients with type 2 diabetes mellitus., Methods: The instrument was derived from a tool created to evaluate psychosocial determinants of adherence to oral antidiabetics medications in the Brazilian context, and was submitted for evaluation by a committee of experts and members of the target population. The item-level content validity index, the scale-level content validity index averaging calculation method, and the modified kappa coefficient were used to evaluate agreement among specialists. The comprehensibility of the instrument by members of the target population was qualitatively analyzed., Results: The item-level content validity index was found to be lower than desired in 6 of the 20 items analyzed. Of these, one item was modified and 5 were excluded after the comprehensibility evaluation by members of the target population; one item from the perceived control scale was excluded. Content validation resulted in an instrument with 14 items, distributed in the domains intention (4 items), attitude (3 items), perceived norm (4 items), and perceived control (4 items) scales., Conclusions: The findings support good evidence of the content validity of the instrument for use among people with type 2 diabetes mellitus receiving insulin therapy., (Copyright © 2021 ISPOR--The professional society for health economics and outcomes research.

Objective: This scoping review aims to identify and understand the different tools and methods used in studies in the field of human eating behavior to assess, measure, or classify participants' ambivalence toward food and diet, as well as to identify which tools and methods are most frequently employed., Introduction: People's attitudes toward food and eating behaviors are often ambivalent (simultaneously positive and negative), making it harder to change eating behaviors in favor of a healthier diet. This highlights the importance of resolving diet-related ambivalence. Identifying and understanding the different methods used in the literature to assess attitudinal ambivalence toward food and diet will provide researchers with a range of options to choose from for future studies., Inclusion Criteria: We will include peer-reviewed studies as well as preprints that assess the ambivalence of human participants toward food and diet, regardless of sex, age, or other sociodemographic factors. We will exclude studies in which the methods used to assess ambivalence are not detailed or cannot be reproduced, as well as studies that assess the ambivalence of participants toward farming and agricultural methods or toward methods of food production and preparation., Methods: This review will follow the JBI methodology for scoping reviews. Peer-reviewed studies will be retrieved from MEDLINE, PsycINFO, Web of Science, Food Science Source, FSTA, and CINAHL, while preprints will be retrieved from PsyArXiv and MedArXiv. Two independent reviewers will screen the articles. All relevant extracted information will be presented as tables and a descriptive summary of the findings., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 JBI.)

Introduction: The recent transformations undergone by Brazilian labor court, especially with the introduction of electronic process of law ( processo judicial eletrônico [PJe]), had a significant influence on how people work., Objectives: This study aimed to evaluate the occurrence of musculoskeletal symptoms and work ability in public sector employees working in a specialized labor court body., Methods: A cross-sectional study was conducted with 449 workers, who provided demographic and occupational information and completed the Nordic Musculoskeletal Questionnaire (NMQ) and the Work Ability Index (WAI)., Results: Symptoms occurred more frequently in wrists/hands (62.4%), shoulders (62.1%), and neck (60.4%) in the past 12 months, and in the neck (29.8%), shoulders (29.4%), and wrists/hands (29.2%) in the past 7 days. The mean WAI score was 38.7 (6.4), and 31.4% of participants had poor or moderate work ability. WAI scores were poorer when participants had previous problems, and the number of body segments involved in complaints was greater among those with inadequate work ability., Conclusions: Higher frequency of musculoskeletal symptoms in wrists/hands, shoulders, and neck may be related to using PJe for work and is associated with poorer work ability scores, highlighting the importance of preventive interventions for work-related musculoskeletal disorders., Competing Interests: Conflicts of interest: None

Background: The implementation of the electronic judicial process (PJe) in recent years is associated with an increase in workload and stricter control through productivity targets in the Brazilian labor judiciary., Objectives: To evaluate the relations between musculoskeletal symptoms, psychosocial factors and work ability in civil servants of a labor justice body in the context of the PJe., Methods: A cross-sectional exploratory study with a quantitative approach involving 449 workers. Sociodemographic, occupational and related data were collected through questionnaires validated in the Brazilian context. Data analysis was conducted by descriptive and inferential statistics: Mann-Whitney test, Spearman's correlation coefficient and multiple linear regression., Results: There was a correlation between musculoskeletal symptoms and psychosocial factors (p < 0.05), as well as between both musculoskeletal symptoms and psychosocial factors with reduced work ability (p < 0.05). The multiple linear regression model pointed to the female gender and the dimensions "demands", "control" and "peer support" as related to the musculoskeletal symptoms., Conclusion: We highlight the importance of a broader approach, involving psychosocial factors in preventive actions related to musculoskeletal disorders considering the important relationship with work ability.

Sensitivity and specificity measurements were performed by means of latent class analysis., Results: The prevalence of the diagnosis was 64.5%. Nausea, dizziness, and vomiting were sensitive and specific; altered heart rate was specific., Conclusion: Four indicators were accurate for the nursing diagnosis., Implications for Nursing: Accurate defining characteristics contribute to reliable and precise assessment and enable nurses to diagnose and intervene in the outcome of the patient's clinical condition., (© 2020 NANDA International, Inc.)

The purpose of this paper is to provide measurement properties evaluation and factor analysis of the Brazilian version of the diabetic foot ulcer scale-short form (DFS-SF). This methodological study evaluated the measurement properties of the DFS-SF by ceiling and floor effect reliability, responsiveness, and structural construct validity. The study included 290 people with diabetic foot under regular follow-up in a specialised outpatient clinic in inland São Paulo. Reliability was assessed by internal consistency using Cronbach's alpha and composite reliability. Ceiling and floor effects were assessed by the percentage of participants who scored the 15% worst (floor) and 15% best (ceiling) possible scale results. Validity was tested by correlating the instrument values with the domains of the Brazilian version of the Short Form Health Survey (SF-36). Responsiveness (n = 34) was accessed through the wound area obtained by photography and evaluated by the Image J Features program and the DFS-SF score at two moments, with a 4-week interval between them. The instrument had good evidence of reliability, shown by adequate internal consistency (Cronbach's alpha in domains >0.70) and compound reliability (0.84 > CC > 0.92); and of convergent validity, by significant positive correlations of moderate to strong magnitude with SF-36. Structural construct validity was examined by applying the DFS-SF confirmatory factor analysis, which indicated that the Brazilian version of the instrument is properly fitted to the original dimensional structure. The ceiling and floor effect analysis showed no ceiling or floor effects. Responsiveness was observed in the wound area, but not in the DFS-SF scores in the times. The Brazilian version of the DFS-SF presented evidence of validity and reliability, suggesting that this instrument is a valid tool for assessing the quality of life of people with diabetic foot in the Brazilian population., (© 2020 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)

Aims and Objectives: The aim of this study was to identify the psychosocial determinants of adherence to oral antidiabetic medication, according to the Theory of Planned Behaviour (TPB)., Background: Appropriate adherence to oral antidiabetic medication contributes to long-term glycaemic control. However, glycaemic control is often poor in people with type 2 diabetes, mainly due to the poor adherence to oral antidiabetic agents., Design: Prospective study with 2 waves of data collection, based on STROBE checklist was conducted. One hundred and fifty-seven adults with type 2 diabetes, in chronic use of oral antidiabetic agents, composed the sample. At baseline, self-reported measures of medication adherence (proportion and global evaluation of adherence) and of metabolic control (glycated haemoglobin) of diabetes were obtained., Methods: The TPB main constructs (attitude, subjective norm and perceived control) and related beliefs were measured. Adherence and metabolic control measurements were obtained in a two-month follow-up (n = 157)., Results: Attitude and subjective norm, together, explained 30% of the variability in intention; their underlying belief-based measures (behavioural and normative beliefs) explained 28% of the variability in intention. In addition, intention predicted behaviour at follow-up. However, when added to the prediction model, past behaviour was the only explanatory factor of adherence behaviour., Conclusion: Adherence behaviour to oral antidiabetic medication was predicted by intention, which, in turn, was determined by attitude and subjective norm. In order to promote adherence to oral antidiabetic agents, health professionals should include motivational strategies as well as strategies targeted to attitude and subjective norm when designing interventions., Relevance to Clinical Practice: The nonadherence to antidiabetic medication contributes to lack of control of diabetes and ensuing complications. The comprehension of the factors explaining the variability in medication adherence can inform the design of theory-based interventions aimed at promoting this behaviour., (© 2019 John Wiley & Sons Ltd.)

The relationship between salt intake and cardiovascular diseases is a contemporary scientific controversy, which has been attributed to the limits of the measures of salt intake used in the studies. Thus, this article sought to systematically review the literature on the methods used to estimate salt intake in different study designs. Of the 124 articles, 60.5% used only biochemical measures, 26.6% only self-report measures and 12.9% reported the combined use of both methods. The 24-hour urinary sodium excretion was the predominant biochemical method (79.1%) and the Food Frequency Questionnaire was the predominant self-report measure (36.4%). Interventional studies used mostly 24-hour urinary sodium excretion; while longitudinal studies used self-report measures. The question guiding the study and its design, as well as constraints related to costs, sample size and feasibility seems to influence the choice of the type of measurement.

Objective: To assess salt intake and its dietary sources using biochemical and self-report methods and to characterize salt intake according to sociodemographic and disease-related variables in a sample of the Brazilian population., Design: Population-based cross-sectional survey., Setting: Salt intake was assessed by biochemical (24 h urinary Na excretion) and self-report methods (sodium FFQ, 24 h dietary recall, seasoned-salt questionnaire, discretionary-salt questionnaire and total reported salt intake).ParticipantsAdults and older people (n 517) aged 20-80 years, living in Artur Nogueira, São Paulo, Brazil., Results: Mean salt intake based on 24 h urinary Na excretion and total reported salt intake was 10·5 and 11·0 g/d, respectively; both measures were significantly correlated. Discretionary salt and seasoned salt were the most important sources of salt intake (68·2 %). Men in the study consumed more salt than women as estimated by 24 h urinary Na excretion (11·7 v. 9·6 g salt/d; P&lt;0·0001). Participants known to be hypertensive added more salt to their meals but consumed less salty ultra-processed foods. Waist circumference in both sexes and BMI were positively correlated with salt intake estimated by 24 h urinary Na excretion. In addition, regression analysis revealed that being a young male or having a high waist circumference was a predictor of higher salt intake., Conclusions: Salt intake in this population was well above the recommended amount. The main source of salt intake came from salt added during cooking. Salt intake varied according to sex and waist circumference.

Background: Non-adherence to oral antidiabetics drugs (OADs) has been a common problem and may contribute to poor glycemic control., Aim: To describe an experimental study protocol that aims at implementing and evaluating the effect of the "action planning and coping planning" interventions on medication adherence to OADs in patients with type 2 diabetes mellitus (T2DM) in follow-up at primary care services., Design: A randomized controlled trial., Methods: Two groups (intervention and control) will be followed over a period of 105 days. The intervention group will receive a combination of the "action planning" and "coping planning" intervention strategies. There will be in-person meetings and phone calls to reinforce the intervention. The control group will receive the usual care from the health unit., Conclusions: It is hoped that this study will help health professionals to improve their approach with patients who have T2DM in relation to medication adherence.

Background: Excessive salt intake has been directly associated with cardiovascular diseases, especially hypertension, and non-cardiovascular diseases. Despite the current recommendations, salt intake remains high, indicating the need to develop theory-based interventions aimed at reducing this intake., Aim: The purpose of this study was to test the impact of a theory-based intervention - the SALdável Program - to promote the use of less than 4 g of salt/day during cooking., Methods: This was a two-arm parallel-group randomized study. A total of 92 hypertensive women were randomly assigned to an intervention or control group. The intervention was aimed at motivating participants to reduce salt addition by increasing self-efficacy and counteracting the negative influence of habit. Primary outcomes were the behavioral question of salt addition and total salt addition, secondary outcomes were overall salt intake, provided by 24-hour urinary sodium excretion, and psychosocial variables (intention, self-efficacy, and habit)., Results: At three-month follow-up, the intervention group improved significantly more than the control group regarding salt addition measures (p-values between 0.05 and 0.001) and psychosocial variables (all p-values ⩽0.001). The reduction in 24-hour urinary sodium excretion was not significant., Conclusion: The findings showed that this theory-based intervention was effective to motivate and change the behavior of hypertensive women regarding daily salt use in cooking meals. This was accomplished by means of improvements in intention and self-efficacy and reduction of the habit of using more than 4 g of salt/day during cooking., (© The European Society of Cardiology 2015.)

Objective: to compare the general and specific health-related quality of life (HRQoL) between the Intervention (IG) and Control (CG) groups of coronary artery disease patients after the implementation of Action Planning and Coping Planning strategies for medication adherence and to verify the relationship between adherence and HRQoL., Method: this was a controlled and randomized study., Results: the sample (n=115) was randomized into two groups, IG (n=59) and CG (n=56). Measures of medication adherence and general and specific HRQoL were obtained in the baseline and after two months of monitoring., Conclusion: the findings showed that the combination of intervention strategies - Action Planning and Coping Planning for medication adherence did not affect the HRQoL of coronary artery disease patients in outpatient monitoring.

Aim: To examine the effect of action and coping planning strategies in the adherence to medication among outpatients with coronary artery disease., Background: Action and coping planning strategies are based on implementation intention, which requires self-regulation by the individual, to prioritize intentionally planned responses over learned or habitual ones, from daily routines to stressful situations., Design: Randomized controlled trial., Methods: Participants (n = 115) were randomized into intervention (use of action and coping planning strategies, n = 59) or control (usual care, n = 56) groups. The study was conducted between June 2010-May 2011 in two in-person visits: baseline and 2-month follow-up. Participants in the intervention group received telephone reinforcement between baseline and 2-month follow-up. Adherence to medication for cardioprotection and symptoms relief was evaluated by proportion of adherence, global measure of adherence evaluation and Morisky Self-Reported Measure of Medication Adherence Scale at both baseline and 2-month follow-up., Findings: When using the measure of global measure of adherence, participants in the intervention group reported adherence to therapy more often than controls (odds ratio = 5.3), but no statistically significant change was observed in the other two outcome measures., Conclusion: This study has shown that individuals who use action and coping planning report higher adherence to drug treatment, when measured by the global adherence evaluation. Further studies with longer follow-ups are needed to assess if the effect of planning strategies has long-term duration., (© 2013 John Wiley & Sons Ltd.)

Objective: to identify salient behavioral, normative, control and self-efficacy beliefs related to the behavior of adherence to oral antidiabetic agents, using the Theory of Planned Behavior., Method: cross-sectional, exploratory study with 17 diabetic patients in chronic use of oral antidiabetic medication and in outpatient follow-up. Individual interviews were recorded, transcribed and content-analyzed using pre-established categories., Results: behavioral beliefs concerning advantages and disadvantages of adhering to medication emerged, such as the possibility of avoiding complications from diabetes, preventing or delaying the use of insulin, and a perception of side effects. The children of patients and physicians are seen as important social references who influence medication adherence. The factors that facilitate adherence include access to free-of-cost medication and taking medications associated with temporal markers. On the other hand, a complex therapeutic regimen was considered a factor that hinders adherence. Understanding how to use medication and forgetfulness impact the perception of patients regarding their ability to adhere to oral antidiabetic agents., Conclusion: medication adherence is a complex behavior permeated by behavioral, normative, control and self-efficacy beliefs that should be taken into account when assessing determinants of behavior.

This was a systematic review aimed at identifying and characterizing measuring instruments, developed in the context of cardiology, which were adapted into Portuguese language of Brazil. Systematic searches were performed in six databases. Information extracted included cultural adaptation process and measurement properties. To assess the methodological quality of studies, criteria based on international guidelines for cultural adaptation of instruments were used. Among the 114 articles found, 14 were eligible for review. Of these, most evaluated quality of life (35.7%) and health knowledge/learning (28.6%). Most studies followed all stages of the adaptation process recommended in the literature. With respect to measurement properties, internal consistency, verified by Cronbach's alpha, was the property reported in the majority of the studies, as well as construct and criterion validity. This study is expected to provide to the scientific community a critical evaluation of adapted questionnaires available in the context of cardiology.

This experimental study was aimed at assessing the potential effect of a theory-driven intervention-implementation intentions-on reducing salt intake among hypertensive Brazilian women. Ninety-eight participants were randomly assigned to participate in an implementation intentions intervention aimed at promoting lower salt intake through decreased addition of salt and salty spices to meals (intervention group, n = 49; group, n = 49). Endpoints were assessed at baseline and at the 2-month follow-up. Primary endpoints were a self-reporting measure of salt intake given by salt addition to meals (discretionary salt + salty spices = total added salt) and the 24 h urinary-sodium excretion. Secondary endpoints included intention, self-efficacy, and habit related to adding salt to meals. Patients in the intervention group showed a significant reduction in salt intake as assessed by 24 h urinary-sodium excretion. A significant reduction in the measure of habit was observed for both groups. No differences were observed for intention and self-efficacy. The results of this pilot study suggest the efficacy of planning strategies to help hypertensive women reduce their salt intake.

Objective: To evaluate the relationship between the behaviors of salt consumption and socio-demographic and clinical variables., Method: Sodium consumption was evaluated using the methods: self-reporting (considering 3 different behaviors related to salt consumption), 24- hr dietary recall, discretionary salt, food frequency questionnaire, estimation of total sodium intake and 24-hr urinary excretion of sodium (n=108)., Results: Elevated salt intake according to the different measurements of consumption of the nutrient was associated with the variables: male sex, low level of schooling and monthly income, being Caucasian, and being professionally inactive; and with the clinical variables: elevated Body Mass Index, tensional levels, ventricular hypertrophy and the number of medications used., Conclusion: The data obtained shows a heterogenous association between the different behaviors related to salt consumption and the socio-demographic and clinical variables. This data can be used to optimize the directing of educational activities with a view to reducing salt consumption among hypertensives.

Background: Despite strong evidence for a relationship between high salt intake and hypertension, plus the widespread recommendations for dietary salt restriction among hypertensive subjects, there are no nursing studies describing effective theory-based interventions., Aim: To describe a systematic process for development of a theory-based nursing intervention that is aimed at reducing salt intake among hypertensive women, by applying the 'intervention mapping' protocol., Methods: We developed our intervention following the six steps of the 'intervention mapping' protocol: assessing needs, creating a matrix of change objectives, selecting theoretical methods and practical applications, defining the intervention programme, organizing the adoption and implementation plan, and defining the evaluation plan., Results: Addition of salt during cooking is identified as the main source for salt consumption, plus women are identified as the people responsible for cooking meals at home. In our study, the motivational predictors of this behaviour were self-efficacy and habit. Guided practice, verbal persuasion, coping barriers, consciousness-raising and counter-conditioning were the theoretical methods we selected for enhancing self-efficacy and promoting habit change, respectively. Brainstorming, role-playing, cookbook use, measuring spoon use, label reading, hands-on skill-building activities and reinforcement phone calls were the chosen practical applications. We designed our intervention programme, and then organized the adoption and implementation plans. Finally, we generated a plan to evaluate our intervention., Conclusions: 'Intervention mapping' was a feasible methodological framework to guide the development of a theory-based nursing intervention for dietary salt reduction among hypertensive women.

Aim: this paper reports the results of a nursing-administered theory-based intervention, the "Moving Heart Program", based on the implementation intention theory and pointed at improving physical activity adherence among coronary heart disease outpatients in Brazil., Methods: this experimental study applied assessments at baseline, 1 and 2 months after baseline. The Consolidated Standards of Reporting Trials statement was followed. Participants were randomly assigned to intervention, comprising action and coping plans on how to deal with anticipated barriers (n=69), or a standard-care control group (n=67)., Results: participants submitted to the intervention showed significant higher levels of physical activity 2 months after baseline and were significantly more active than the control group., Conclusions: the results indicate that the intervention is feasible for patients with coronary heart disease and can be a useful tool to facilitate intended lifestyle changes. This study brings relevant contributions to the Nursing field and other health-related areas, once the intervention presents low cost to health services and can be applied in cardiac rehabilitation programs, showing significant benefits to participants.

Objective: To present a conceptual framework based on the PRECEDE model conceived to guide research and the clinical practice of nurses in the clinical follow-up of patients with cardiovascular diseases., Method: The conceptual bases as well as the study designs used in the framework are discussed. The contextualization of the proposed structure is presented in the clinical follow-up of hypertensive patients. Examples of the intervention planning steps according to the intervention mapping protocol are provided., Results: This conceptual framework coherently and rationally guided the diagnostic steps related to excessive salt intake among hypertensive individuals, as well as the development and assessment of specific interventions designed to change this eating behavior., Conclusion: The use of this conceptual framework enables a greater understanding of health-related behaviors implied in the development and progression of cardiovascular risk factors and is useful in proposing nursing interventions with a greater chance of success. This model is a feasible strategy to improve the cardiovascular health of patients cared for by the Brazilian Unified Health System.

Objective: to validate the content of persuasive messages for promoting walking among patients with coronary heart disease (CHD). The messages were constructed to strengthen or change patients' attitudes to walking., Method: the selection of persuasive arguments was based on behavioral beliefs (determinants of attitude) related to walking. The messages were constructed based in the Elaboration Likelihood Model and were submitted to content validation., Results: the data was analyzed with the content validity index and by the importance which the patients attributed to the messages' persuasive arguments. Positive behavioral beliefs (i.e. positive and negative reinforcement) and self-efficacy were the appeals which the patients considered important. The messages with validation evidence will be tested in an intervention study for the promotion of the practice of physical activity among patients with CHD.

Objective: to analyze the action and coping plans related to the behavior of adhering to drug therapy, developed by coronary heart disease (CHD) outpatients, and to identify the barriers perceived to adopting this behavior., Methods: the participants (n=59) were invited to formulate action plans and coping plans for the behavior of adhering to the cardio-protective medications and the symptom-relief medications., Results: specific action plans for taking the medications associated with temporal markers and the sleep-wake cycle were shown. The most frequently reported obstacles were forgetfulness and absence of routine in daily living activities. The coping plans for overcoming forgetfulness were the most specific., Conclusion: this study's findings support the application of implementation intentions aimed at optimizing adherence to drug therapy among patients with CHD.

Background: High salt consumption among populations remains a challenge for health professionals dealing with prevention and control of hypertension. The present study aimed to identify the psychosocial predictors of salt consumption among hypertensive individuals, based on an extended version of the Theory of Planned Behaviour (TPB). Three salt consumption behaviours were studied: Behaviour 1- using <4 g of salt per day during cooking; Behaviour 2- avoiding adding salt/table salt use to the prepared foods; and Behaviour 3- avoiding the consumption of foods with high salt content., Methods: At baseline (n = 108), TPB and additional variables (self-efficacy, habit, past behaviour, hedonic determinant, self-perceived diet quality) were measured. At 2-month follow-up (n = 95), the three behaviours were assessed. Behaviour and intention were sequentially regressed on the study variables, using polytomous logistic regression and hierarchical linear regression with rank transformation, respectively., Results: Behaviour 1 was predicted by intention [odds ratio (OR) = 6.23; 95% confidence interval (CI) = 1.81-21.52], whereas self-efficacy and habit predicted intention. Behaviour 2 exhibited high score mean and low variation and was predicted by self-perceived diet quality (OR = 2.56; 95% CI = 1.03-6.36). Behaviour 3 was predicted by the hedonic determinant (OR = 1.42; 95% CI = 1.01-1.98)., Conclusions: The results indicate that salt-related behaviours are explained by a variety of determinants. Among these determinants, special consideration should be given to motivational and hedonic aspects., (© 2012 The Authors.

This cross-sectional study, based in implementation intention theory, describes action plans developed by women with hypertension (n=49) to add no more than 4g of salt per day to food and to reduce consumption of salty foods, as well as describing the barriers perceived and the coping strategies adopted for putting the action plans into practice. The plans were categorized according to similarities and were submitted to frequency analysis. The majority of the action and coping plans had to do with the effectuation of the behavior involving adding up to 4g of salt per day per person to food. The action strategies were aimed at quantifying the salt added, and the main obstacles were related to the reduced palatability of the food made with less salt. The coping plans have to do with preparing foods separately and to using natural seasonings instead of salt. This data can help the nurse to design activities for clinical education, with a view to reducing salt consumption among patients who prepare their own food.

The mechanisms by which dietary sodium modulates cardiovascular risk are not fully understood. This study investigated whether sodium intake is related to carotid structure and hemodynamics and to plasma matrix metalloproteinase (MMP) activity in hypertensive adults. One hundred thirty-four participants were cross-sectionally evaluated by clinical history, anthropometry, carotid ultrasound, and analysis of hemodynamic, inflammatory, and metabolic variables. Daily sodium intake (DSI) was estimated by 24-h recall, discretionary sodium, and a FFQ. In 42 patients, plasma MMP-2 and MMP-9 activities were also analyzed. The mean DSI was 5.52 ± 0.29 g/d. Univariate analysis showed that DSI correlated with common carotid artery systolic and diastolic diameter (r = 0.36 and 0.34; both P < 0.001), peak and mean circumferential tension (r = 0.44 and 0.39; both P < 0.001), Young's Elastic Modulus (r = 0.40; P < 0.001), intima-media thickness (r = 0.19; P < 0.05), and internal carotid artery resistive index (r = 0.20; P < 0.05). Multivariate analyses revealed that only artery diameter, circumferential wall tension, and Young's Elastic Modulus were independently associated with DSI. Conversely, plasma MMP-9 activity was associated with DSI (r = 0.53; P < 0.001) as well as with common carotid systolic diameter (r = 0.33; P < 0.05) and Young's Elastic Modulus (r = 0.38; P < 0.01). In conclusion, sodium intake is associated with carotid alterations in hypertensive adults independently of systemic hemodynamic variables. The present findings also suggest that increased MMP-9 activity might play a role in sodium-induced vascular remodeling.

Objective: The aim of this study was to investigate the relationship between beliefs regarding a low salt diet and the nutritional behavior of sodium consumption as well their relation with sociodemographic and clinical variables among chronic renal failure (CRF) patients on dialysis., Design and Methods: This cross-sectional study enrolled a sample of 117 patients who answered the Brazilian version of the Beliefs about Dietary Compliance Scale (BDCS), the sodium frequency food questionnaire, and the use of discretionary salt/day., Results: The average of total salt consumption was 10.6 g/day (±6.3) and it was positively correlated with the interdialytic weight gain (r = 0.20 P = .032) and negatively correlated with the education level (r = -0.19 P = .044). The Benefits beliefs were discriminatory of the higher and lower salt consumers, and proportionally related to monthly income (r = 0.22 P = .017). The Barriers beliefs were positively correlated only to time on dialysis (r = 0.25 P = .008). Subjects with lower schooling and those of older age tended to consume more discretionary salt (r = -0.27, P = .005; r = 0.23, P = .016, respectively); however, they reported a lower consumption of foods with high salt content (r = 0.25 P = .006; r = -0.27 P = .004)., Conclusions: Educational interventions aimed at reducing salt consumption for this group must include interventions targeted at different behaviors related to overall salt consumption, the specificities of age, and level of schooling of the patients., (Copyright © 2011 National Kidney Foundation, Inc.

The aim of this study was to report the development and the analysis of content validity and reliability of the Psychosocial Determinants of Physical Activity among Coronary Heart Disease Patients Questionnaire, based on an extension of the Theory of Planned Behavior. In the content validity step, three experts evaluated the instrument which was, afterwards, pre-tested with five subjects in order to obtain a conceptually appropriate and easily understood instrument. Fifty-one patients participated in the evaluation of internal consistency of the reviewed instrument. Cronbach's alpha coefficients above 0.75 were observed for the constructs: Intention, Attitude, Subjective Norm, Self-efficacy and Habit. The new instrument demonstrated acceptable evidence of content validity and reliability.
