RESUMO
BACKGROUND: The association between iron biomarkers and cardiovascular disease risk factors (CVD-RFs) remains unclear. We aimed to (1) evaluate the cross-sectional and longitudinal associations between iron biomarkers (serum ferritin, transferrin saturation (TSAT), transferrin) and CVD-RFs among women, and (2) explore if these associations were modified by menopausal status. METHOD: Cross-sectional and longitudinal analyses including 2542 and 1482 women from CoLaus cohort, respectively. Multiple linear regression and multilevel mixed models were used to analyse the associations between Iron biomarkers and CVD-RFs. Variability of outcomes and iron markers between surveys was accessed using intraclass correlation (ICC). RESULTS: After multivariable adjustment, elevated serum ferritin levels were associated with increased insulin and glucose levels, while higher transferrin levels were linked to elevated glucose, insulin and total cholesterol, and systolic and diastolic blood pressure (p < 0.05). No association was observed between CVD-RFs and TSAT (p > 0.05). Iron biomarkers demonstrated low reliability across reproductive stages but exhibited stronger associations in the perimenopausal group. In longitudinal analysis, we found association only for transferrin with lower glucose levels [ß = - 0.59, 95% CI (- 1.10, - 0.08), p = 0.02] and lower diastolic blood pressure [ß = - 7.81, 95% CI (- 15.9, - 0.56), p = 0.04]. CONCLUSION: In cross-sectional analysis, transferrin was associated with several CVD-RFs, and the associations did not change according to menopausal status. Conversely, in the longitudinal analyses, changes in transferrin were associated only with lower glucose and diastolic blood pressure levels. These differences might stem from the substantial longitudinal variation of iron biomarkers, underscoring the need for multiple iron measurements in longitudinal analyses.

PURPOSE: The aim of this study was to examine the interaction between screen time and cardiorespiratory fitness (CRF) in their longitudinal association with waist circumference (WC) during a follow-up of 3 years from childhood to adolescence. METHODS: Observational 3-year longitudinal study with 401 students (224 females), seven to 15 years of age at baseline. The CRF was evaluated by estimating peak oxygen uptake (VO2peak) from an indirect field-based test and body mass index. Screen time was assessed using self-reported questionnaires. Moderation analyses were tested using a multiple linear regression model with adjustments for sex, age, puberty stage, and ethnicity. RESULTS: A statistically significant interaction term was observed (B = -0.0003; 95% CI: -0.007; -0.0001). Since screen time was contextualized as the independent variable, the results show that relationship between screen time and WC varies across different CRF levels. CONCLUSION: The findings suggest that higher CRF can attenuate the harmful association that increased sedentary behavior might have on abdominal adiposity.

Global targets to reduce salt intake have been proposed, but their monitoring is challenged by the lack of population-based data on salt consumption. We developed a machine learning (ML) model to predict salt consumption at the population level based on simple predictors and applied this model to national surveys in 54 countries. We used 21 surveys with spot urine samples for the ML model derivation and validation; we developed a supervised ML regression model based on sex, age, weight, height, and systolic and diastolic blood pressure. We applied the ML model to 54 new surveys to quantify the mean salt consumption in the population. The pooled dataset in which we developed the ML model included 49,776 people. Overall, there were no substantial differences between the observed and ML-predicted mean salt intake (p<0.001). The pooled dataset where we applied the ML model included 166,677 people; the predicted mean salt consumption ranged from 6.8 g/day (95% CI: 6.8-6.8 g/day) in Eritrea to 10.0 g/day (95% CI: 9.9-10.0 g/day) in American Samoa. The countries with the highest predicted mean salt intake were in the Western Pacific. The lowest predicted intake was found in Africa. The country-specific predicted mean salt intake was within reasonable difference from the best available evidence. An ML model based on readily available predictors estimated daily salt consumption with good accuracy. This model could be used to predict mean salt consumption in the general population where urine samples are not available.

BACKGROUND: While we have good evidence about the hypertension care cascade, we do not know the mean blood pressure (BP) in these groups. We described the mean BP in four groups based on the hypertension care cascade at the national and sub-national levels in Peru. METHODS: Descriptive analysis of six national health surveys. Blood pressure was measured twice and the second record herein analysed. We defined four groups: i) people with self-reported hypertension diagnosis receiving antihypertensive medication; ii) people with self-reported hypertension diagnosis not receiving antihypertensive medication; iii) people unaware they have hypertension with blood pressure ≥140 or 90 mmHg; and iv) otherwise healthy people. FINDINGS: There were 125,066 people; mean age was 49.8 years and there were more women (51.7%). At the national level, in men and women and throughout the study period, we observed that the mean systolic BP (SBP) was the highest in people unaware they have hypertension; the mean SBP was similar between those with and without antihypertension medication, yet slightly higher in the former group. At the sub-national level, even though the mean SBP in the unaware group was usually the highest, there were some regions and years in which the mean SBP was the highest in the untreated and treated groups. INTERPRETATION: These results complement the hypertension care cascade with a clinically relevant parameter: mean BP. The results point where policies may be needed to secure effective interventions to control hypertension in Peru, suggesting that improving early diagnosis and treatment coverage could be priorities.

RESUMO
Background: High neck circumference (NC) is associated with high burden diseases in Latin American and the Caribbean (LAC). NC complements established anthropometric measurements for early identification of cardio-metabolic and other illnesses. However, evidence about NC has not been systematically studied in LAC. We aimed to estimate the mean NC and the prevalence of high NC in LAC. Methods: We conducted a systematic review in MEDLINE, Embase, Global Health and LILACS. Search results were screened and studied by two reviewers independently. To assess risk of bias of individual studies, we used the Hoy et al. scale and the Newcastle-Ottawa scale. We conducted a random-effects meta-analysis. Results: In total, 182 abstracts were screened, 96 manuscripts were reviewed and 85 studies (n= 51,978) were summarized. From all the summarized studies, 14 were conducted in a sample of the general population, 23 were conducted with captive populations and 49 studies were conducted with patients. The pooled mean NC in the general population was 35.69 cm (95% IC: 34.85cm-36.53cm; I²: 99.6%). In our patient populations, the pooled mean NC in the obesity group was 42.56cm (95% CI 41.70cm-43.42cm; I²: 92.40%). Across all studied populations, there were several definitions of high NC; thus, prevalence estimates were not comparable. The prevalence of high NC ranged between 37.00% and 57.69% in the general population. The methodology to measure NC was not consistently reported. Conclusions: Mean NC in LAC appears to be in the range of estimates from other world regions. Inconsistent methods and definitions hamper cross-country comparisons and time trend analyses. There is a need for consistent and comparable definitions of NC so that it can be incorporated as a standard anthropometric indicator in surveys and epidemiological studies.
RESUMO
BACKGROUND: Influenza vaccination (IV) and Pneumococcus vaccination (PV) are recommended for patients with cardiometabolic diseases. This study aimed to evaluate the immunization rate of ambulatory cardiometabolic patients during the COVID-19 pandemic in the Americas. METHODS: Electronic surveys were collected from 13 Spanish speaking countries between 15 June and 15 July 2020. RESULTS: 4216 patients were analyzed. Mean age 60 (±15) years and 49% females. Global IV rate was 46.5% and PV 24.6%. Vaccinated patients were older (IV = 63 vs. 58 years; PV = 68 vs. 59, p < 0.01) but without gender difference. Vaccination rates were greater in higher-risk groups (65+, diabetics, heart failure), but not in coronary artery disease patients. In the Southern cone, the rate of IV and PV was approximately double that in the tropical regions of the Americas. In a multivariate model, geographic zone (IV = OR 2.02, PV = OR 2.42, p < 0.001), age (IV = OR 1.023, PV = OR 1.035, p < 0.001), and incomes (IV = OR 1.28, PV = OR 1.58, p < 0.001) were predictors for vaccination. CONCLUSIONS: During the COVID-19 pandemic, ambulatory patients with cardiometabolic diseases from the Americas with no evidence of COVID-19 infection had lower-than-expected rates of IV and PV. Geographic, social, and cultural differences were found, and they should be explored in depth.
RESUMO
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which causes coronavirus disease 2019 (COVID-19) has resulted in a global health crisis. Prior to the arrival of this viral pandemic, the world was already plagued with a significant burden of cardiovascular disease. With the introduction of the novel virus, the world now faces a double jeapordy. Early reports have suggested an increased risk of death in individuals with underlying cardio-metabolic disorders. The exact effects of COVID-19 on the cardiovascular system are not well determined, however lessons from prior viral epidemics suggest that such infections can trigger acute coronary syndromes, arrhythmias and heart failure via direct and indirect mechanisms. In this article, we aimed to discuss the effects and potential underlying mechanisms of COVID -19 as well as potential implications of treatments targeted against this virus on the cardiovascular system.

RESUMO
An association between nutritional characteristics in theearlylife stages and the state of the cardiovascular (CV) system in early childhood itself and/or at the beginning of adulthood has been postulated. It is still controversial whether changes in weight, height and/or body mass index (BMI) during childhood or adolescence are independently associated with hemodynamics and/or arterial properties in early childhood and adulthood. AIMS: First, to evaluate and compare the strength of association between CVproperties (at 6 and 18 years (y)) and (a) anthropometric data at specific growth stages (e.g., birth, 6 y, 18 y) and (b) anthropometric changes during early (0-2 y), intermediate (0-6 y), late (6-18 y) and global (0-18 y) growth. Second, to determine whether the associations between CVproperties and growth-related body changes depend on size at birth and/or at the time of CVstudy. Third, to analyze the capacity of growth-related body size changes to explain hemodynamic and arterial properties in early childhood and adulthood before and after adjusting for exposure to CV risk factors. Anthropometric, hemodynamic (central, peripheral) and arterial parameters (structural, functional; elastic, transitional and muscular arteries) were assessed in two cohorts (children, n = 682; adolescents, n = 340). Data wereobtained and analyzed following identical protocols. RESULTS: Body-size changes in infancy (0-2 y) and childhood (0-6 y) showed similar strength of association with CV properties at 6 y. Conversely, 0-6, 6-18 or 0-18 ychanges were not associated with CV parameters at 18 y. The association between CV properties at 6 yand body-size changes during growth showed: equal or greater strength than the observed for body-size at birth, and lower strength compared to that obtained for current z-BMI. Conversely, only z-BMI at 18 y showed associations with CV z-scores at 18 y. Body size at birth showed almost no association with CVproperties at 6 or 18 y. CONCLUSION: current z-BMI showed the greatest capacity to explain variations in CV properties at 6 and 18 y. Variations in some CV parameters were mainly explained by growth-related anthropometric changes and/or by their interaction with current z-BMI. Body size at birth showed almost no association with arterial properties at 6 or 18 y.
RESUMO
Resumen Un estudio de corte transversal realizado entre 2012-2014 en adultos autónomos de Bogotá, mostró una prevalencia de 23% de demencia, encontrándose asociada con baja escolaridad, edad avanzada e hipertensión arterial. La relación de estos factores de riesgo con la progresión del dete rioro cognitivo no ha sido estudiada en nuestra población. Objetivo: evaluar la asociación entre factores de riesgo cardiometabólicos o sociales con la progresión a deterioro cognitivo leve (DCL) o demencia, en adultos autónomos de Bogotá. Material y métodos: una cohorte de sujetos normales y con DCL, del estudio de 2012-2014, se revaluó aplicándose el protocolo neuropsiquiátrico y neuropsicológico del estudio anterior. Se realizaron análisis de correspondencia múltiple y de regresión logística. Resultados: se revaluaron 215 adultos autónomos, 118 sujetos habían sido diagnosticados con cognición normal y 97 con DCL en el primer estudio; 73% fueron mujeres con edad promedio de 71(DE:7.3) años y escolaridad de 8.2 (DE: 5.4) años. Progresaron a demencia 6% de los sujetos en un tiempo de 4(DE:1) años. Un 75% de sujetos normales permaneció sin cambio y 22% progresó a DCL; mientras que 65% de sujetos con DCL no tuvo cambios y un 25% se normalizó. Progresar de normal a DCL se asoció con baja escolaridad OR=2.43 (IC95% 1.004-5.91; p=0.049) y de DCL a demencia con IMC<25 OR=6.3 (IC95% 1.26-31; p=0.025). Conclusión: tener baja escolaridad (<5 años) se asoció en los sujetos normales con un mayor riesgo de progresión a DCL, mientras que tener un IMC <25 aumentó el riesgo de progresión a demencia en los sujetos con DCL. No identificamos factores protectores en los sujetos que se nor malizaron. (Acta Med Colomb 2019; 44: 66-74).
Abstract A cross-sectional study carried out between 2012-2014 in autonomous adults of Bogotá showed a 23% prevalence of dementia, being associated with low schooling, advanced age and arterial hy pertension. The relationship between these risk factors and the progression of cognitive deterioration has not been studied in our population. Objective: to evaluate the association between cardio-metabolic or social risk factors with the progression to mild cognitive impairment (MCI) or dementia, in autonomous adults of Bogotá. Material and methods: a cohort of normal subjects with MCI, from the 2012-2014 study was re-evaluated applying the neuropsychiatric and neuropsychological protocol of the previous study. Multiple correspondence and logistic regression analyzes were performed. Results: 215 autonomous adults were re-evaluated; 118 subjects had been diagnosed with normal cognition and 97 with MCI in the first study; 73% were women with an average age of 71 (SD: 7.3) years and schooling of 8.2 (SD: 5.4) years. 6% of the subjects progressed to dementia in a time of 4 (SD: 1) years. 75% of normal subjects remained unchanged and 22% progressed to MCI while 65% of subjects with MCI did not change and 25% normalized. Progressing from normal to MCI was associated with low schooling OR = 2.43 (95% CI 1.004-5.91; p = 0.049) and from MCI to dementia with BMI≤25 OR = 6.3 (IC95% 1.26-31; p = 0.025). Conclusion: having low schooling (≤5 years) was associated in normal subjects with a higher risk of progression to MCI, while having a BMI ≤25 increased the risk of progression to dementia in subjects with MCI. Protective factors in subjects who normalized were not identified. (Acta Med Colomb 2019; 44: 66-74).

The overall aim of this study was to examine the association of physical activity (PA) and screen time (ST) on indicators of cardio-metabolic risk during adolescence, by examining the combined association of PA and ST at ages 11, 15 and 18 on cardio-metabolic risk factors at 18â¯years. Data from the 1993 Pelotas (Brazil) Birth Cohort Study (Nâ¯=â¯3613) were analysed in 2017. Self-reported PA and ST data were collected at 11, 15 and 18â¯years. Cardio-metabolic risk factors (fat mass index, waist circumference, triglycerides, blood glucose, non-HDL cholesterol and resting diastolic blood pressure) were examined at age 18. Multivariate linear regression was used to examine the associations between four mutually exclusive PA/ST groups: 1) active (≥1â¯h/day PA) and low ST (<5â¯h/day ST); 2) active (≥1â¯h/day PA) and high ST (≥5â¯h/day ST); 3) inactive (<1â¯h/day PA) and low ST (<5â¯h/day ST); 4) inactive (<1â¯h/day PA) and high ST (≥5â¯h/day ST) at each age, and outcomes at age 18. There were no significant associations between PA/ST at ages 11 and 15 with outcomes at 18â¯years. In the cross-sectional analyses, adolescents in the most active group had significantly better levels of all the outcomes, regardless of ST. Inactive participants with high ST had the highest levels of glucose and non-HDL-C. For diastolic blood pressure, values were higher among inactive participants. Overall, higher levels of physical activity appeared to be more important than low levels of ST for cardio-metabolic health in adolescents.

The most common tools used to screen for abdominal obesity are waist circumference (WC) and waist-to-height ratio (WHtR); the latter may represent a more suitable tool for the general non-professional population. The objective of this study was to evaluate the association of WHtR, WC, and body mass index with lipidic and non-lipidic cardio-metabolic risk factors and the prediction capability of each adiposity indicator in a sample of school-aged Mexican children. Overall, 125 children aged 6 to 12 years were analyzed. Anthropometric, biochemical, and dietary parameters were assessed. Receiving operating characteristic (ROC) analysis and univariate and multivariate linear and logistic regression analyses were performed. All the three adiposity indicators showed significant areas under the ROC curve (AURC) greater than 0.68 for high low-density lipoprotein cholesterol (LDL-c), triglycerides, and atherogenic index of plasma, and low high-density lipoprotein cholesterol (HDL-c). A significant increased risk of having LDL-c ≥ 3.4 mmol/L was observed among children with WHtR ≥ 0.5 as compared to those with WHtR < 0.5 (odds ratio, OR: 2.82; 95% confidence interval, CI: 0.75â»7.68; p = 0.003). Fasting plasma glucose was not associated with any of the adiposity parameters. WHtR performed similarly to WC and z-BMI in predicting lipidic cardio-metabolic risk factors; however, a WHtR ≥ 0.5 was superior in detecting an increased risk of elevated LDL-c.

OBJECTIVE: Overweight and obesity are risk factors for developing cardiovascular disease. The objective of this study was to determine the prevalence of obesity and risk factors associated with metabolic syndrome and cardiovascular disease in university students. METHODS: 883 students from the Faculty of Medical Sciences of the Central University of Ecuador were included, who were surveyed with demographic data, smoking habits and physical activity. Body mass index, abdominal circumference and blood pressure were determined. Blood chemistry and lipid profile were performed. Central tendency and dispersion measures, average comparisons (Student's T) and Pearson's correlation were calculated to study quantitative variables and χ2 distributed statistic for the comparison of qualitative variables. RESULTS: The prevalence of overweight and obesity was 25.5%. The body mass index was similar in both sexes (23.15 women / 23.57 men), waist circumference was higher in women. Men had higher than normal levels in blood pressure and elevated triglycerides while women had high cholesterol. CONCLUSIONS: One of four students presents some degree of overweight or obesity and an important percentage of altered levels of plasma lipids and blood pressure. Blood glucose levels were found in normal ranges.

Nutrition has been established as a relevant factor in the development of cardiovascular disease (CVD). We aimed to investigate the relationship between the dietary inflammatory index (DII) and cardiometabolic risk parameters in a cohort of 90 overweight and sedentary adults from Bogotá, Colombia. A 24-h dietary record was used to calculate the DII. Body composition variables, flow-mediated dilation (FMD), pulse wave velocity (PWV), lipid profile, glucose, glycosylated hemoglobin (Hb1Ac), and blood pressure were measured and a cardiometabolic risk score (MetScore) was calculated. A lower DII score (anti-inflammatory diet) was significantly associated with higher high-density lipoprotein-cholesterol (HDL-C) and FMD, and lower Hb1Ac and MetScore (p < 0.05). A lower DII score was inversely correlated with plasma triglyceride levels (r = -0.354, p < 0.05), glucose (r = -0.422, p < 0.05), MetScore (r = -0.228, p < 0.05), and PWV (r = -0.437, p < 0.05), and positively with FMD (r = 0.261, p < 0.05). In contrast, a higher DII score (pro-inflammatory diet) showed a positive relationship with MetScore (r = 0.410, p < 0.05) and a negative relationship with FMD (r = -0.233, p < 0.05). An increased inflammatory potential of diet was inversely associated with an improved cardiometabolic profile, suggesting the importance of promoting anti-inflammatory diets as an effective strategy for preventing CVD.

AIMS: To describe the prevalence of abdominal obesity and its association with cardio metabolic risk factors among older adults in Ecuador. MATERIALS AND METHODS: The present study used data from the National Survey of Health, Wellbeing, and Aging survey to examine the prevalence of abdominal obesity according to certain demographic, behavioral, and health characteristics of the participants. Logistic regression models adjusted for potential confounders were used to evaluate the association of abdominal obesity with cardio metabolic risk factors. RESULTS: Of 2053 participants aged 60 years and older, the prevalence of abdominal obesity was 65.9% (95% CI; 62.2%, 69.4%) in women and 16.3% (95% CI; 13.8%, 19.2%) in men. Notably, a higher prevalence of abdominal obesity was seen among residents in the urban areas of the country, those who reported their race as black or mulatto, individuals with sedentary lifestyle and obesity, and older adults with greater number of comorbidities. Moreover, after adjustment for potential confounders, women with abdominal obesity were 2.0, 2.8, and 1.6 times more likely to have diabetes, the metabolic syndrome, and hypertriglyceridemia as compared with those without, respectively. Likewise, men with abdominal obesity had 51% and 22% higher rates of hypertension and diabetes than their non-obese counterparts, respectively. CONCLUSIONS: the prevalence of abdominal obesity is high among older adults in Ecuador. Moreover, abdominal obesity is significantly associated with cardio metabolic risk factors. Therefore, further research is needed to evaluate sociodemographic and nutritional determinants of this emerging public health burden among older Ecuadorians.

Results: 48.2% of the participants had high PAL. 53.7% had one or two altered cardio-metabolic risk factors: low HDL-cholesterol (43%), hypertension (8,7%), hyperglycemia (4%),hypertriglyceridemia (2.7%). 40.9% of women and 35.6% of men achieved optimal results in the evaluation of cardio-respiratory resistance. 49% of males and 34.9% of females obtained optimal results in abdominal strength assessment. 94.6% and 53.7% of participants achieved regular or deficient results in strength assessments of lower and upper limbs, respectively. Conclusions: In the subjects studied, high physical activity level was associated with the male sex, arterial hypertension, hypertriglyceridemia, overweight / obesity, and optimal results of cardio-respiratory resistance and abdominal muscle strength tests.
RESUMO
BACKGROUND & AIMS: In vivo and in vitro evidence suggests that antioxidant vitamins and carotenoids may be key factors in the treatment and prevention of obesity and obesity-associated disorders. Hence, the objective of the present study was to determine the relationship between plasma lipid-soluble antioxidant vitamin and carotenoid levels and adiposity and cardio-metabolic risk markers in overweight and obese adolescents participating in a multidisciplinary weight loss programme. METHODS: A therapeutic programme was conducted with 103 adolescents aged 12-17 years old and diagnosed with overweight or obesity. Plasma concentrations of α-tocopherol, retinol, ß-carotene and lycopene, anthropometric indicators of general and central adiposity, blood pressure and biochemical parameters were analysed at baseline and at 2 and 6 months of treatment. RESULTS: Lipid-corrected retinol (P < 0.05), ß-carotene (P = 0.001) and α-tocopherol (P < 0.001) plasma levels increased significantly, whereas lipid-corrected lycopene levels remained unaltered during the treatment. Anthropometric indicators of adiposity (P < 0.001), blood pressure (P < 0.01) and biochemical parameters (P < 0.05) decreased significantly, whereas fat free mass increased significantly (P < 0.001). These clinical and biochemical improvements were related to changes in plasma lipid-corrected antioxidant vitamin and carotenoid levels. The adolescents who experienced the greatest weight loss also showed the largest decrease in anthropometric indicators of adiposity and biochemical parameters and the highest increase in fat free mass. Weight loss in these adolescents was related to an increase in plasma levels of lipid-corrected α-tocopherol (P = 0.001), ß-carotene (P = 0.034) and lycopene (P = 0.019). CONCLUSIONS: Plasma lipid-soluble antioxidant vitamin and carotenoid levels are associated with reduced adiposity, greater weight loss and an improved cardio-metabolic profile in overweight and obese adolescents.

BACKGROUND: Latin America is facing an increasing burden of nutrition-related non-communicable disease. Little is known about dietary patterns in Guatemalan adults and how dietary patterns are associated with cardio-metabolic disease (CMD) risk. METHODS: This analysis is based on data from a 2002-04 follow-up study of the INCAP Nutrition Supplementation Trial Longitudinal Cohort. Diet data were collected using a validated, semi-quantitative food frequency questionnaire. We derived dietary patterns using principal components analysis. CMD risk was assessed by anthropometry (body mass index, waist circumference), biochemistry (fasting blood glucose and lipids), and clinical (blood pressure) measures. We used sex-stratified multivariable log binomial models to test associations between dietary pattern tertile and CMD risk factors. The sample included 1,428 participants (681 men and 747 women) ages 25-43 years. RESULTS: We derived 3 dietary patterns (traditional, meat-based modern, and starch-based modern), collectively explaining 24.2% of variance in the diet. Dietary patterns were not associated with most CMD risk factors; however, higher starch-based modern tertiles were associated with increased prevalence of low high density lipoprotein cholesterol (HDL-c) in men (Prevalence Ratio (PR) 1.17, 95% Confidence Interval (CI) 1.01, 1.20 for tertile 2; PR 1.20, 95% CI 1.00, 1.44 for tertile 3; p trend 0.04). Higher traditional tertile was associated with increased prevalence of abdominal obesity in women (PR 1.24, 95% CI 1.07, 1.43 for tertile 2; PR 1.19, 95% CI 1.02, 1.39 for tertile 3; p trend 0.02) but marginally significant reduced prevalence of low HDL-c in men (PR 0.88, 95% CI 0.76, 1.00 for tertile 2; PR 0.85, 95% CI 0.72, 1.00 for tertile 3; p trend 0.05). CONCLUSION: Our findings suggest the presence of two 'modern diet' patterns in Guatemala - one of which was associated with increased prevalence of low HDL-c in men. The association between the traditional dietary pattern and some CMD risk factors may vary by sex.
RESUMO
Introducción: La enfermedad cardiovascular constituye una de las primeras causas de mortalidad a nivel mundial y son un problema de salud pública. Objetivo: Determinar la frecuencia de los factores de riesgo cardiovascular en la población rural adulta, que asisten en la USF del distrito de Capitán Miranda Itapúa 2017. Materiales y Métodos: tipo descriptivo de corte transversal, la muestra estuvo constituida por 100 sujetos de la zona rural que asisten en la USF del distrito de capitán Miranda, pacientes de la USF de dicho distrito, durante los meses de abril y mayo del 2017, a quienes se aplicó una recolección de datos, evaluación antropométrica y de presión arterial, el instrumento de porcentaje de RCV en los próximos 10 años de la ACC/AHA en 52 pacientes que contaban con la edad para el estimador. Resultados: La mediana de edad fue de 40±20 años y 66% de los participantes fueron mujeres. EL 37% de los pacientes tuvo Sobrepeso con promedio de 26,9 (±4,2).

El 64% un HDL normal. El 90% no presenta diabetes. El 88% no fuma. Mientras que el 88% no realiza actividad física. De los 100 sujetos a 52% se le realizo el estimador de riesgo cardiovascular a 10 años de las cuales 76,9% presento riesgo bajo. De acuerdo a los resultados se planteo las medidas de prevención pertinente. En conclusión: En la presente investigación se pudo identificar una alta incidencia de factores de riesgo cardiovascular modificables tales como hipertensión, diabetes y actividad física en la población en estudio y una menor incidencia de tabaquismo, colesterol total y HDL
Introduction: Cardiovascular disease it is one of the first causes of mortality worldwide and represent a public health problems. Abstract : The objective of this Study was to determine the frequency of cardiovascular risk factors in the resident population that lives in the countryside of the District of Capitan Miranda, Itapúa, Paraguay 2017. Materials and Methods: Descriptive and cross-sectional Study, in which participated a hundred patients from the countryside of Capitan Miranda, patients attending at the Doctor office during the months of April and May of2017. Biochemical indicator were quantified in serum samples from 100 subjects and estimated anthropometric indicators to determine the frequency of alterations in cardio metabolic biomarkers. The risk estimator is a tool that was applet to 52 subjects to estimate 10-year risks for atherosclerotic cardiovascular disease (ASCVD) ACC /AHA Results: The middle age was 40±20 years old and 66 % of the subjects were women. 37 % with respect to the average are overweight, with average 26,9±4,2. 39% present a high CVR in accordance with waist circumference, 60% are not taking medications for hypertension, 60% C-LDL are in optimal levels and 64 % with HDL is suitable, 90 % are not diabetic. Only the 12 % are smokers and 88 % do not engage in physical activity. From the 100 patients to a 52 was performed the 10 year ASCVD risk estimator, the 76,9 % show a low cardiovascular risk. Conclusion: In this research study we find a low incidence of modifiable cardiovascular risk factors such as Cholesterol LDL, C- HDL, smoker in the other side, hypertension was the highest cardiovascular risk factor 40% found followed by diabetic 10 % of all subjects.
