The explanation of educational disparities in adiposity by lifestyle, socioeconomic and mental health mediators: a multiple mediation model.

BACKGROUND: The inverse association between education and obesity was previously found in numerous studies. This study aims to assess several possible mediators in the educational disparities in adiposity. We hypothesize the potential mediating role of lifestyle, socioeconomic, and mental health factors in the association between education and adiposity. METHODS: Cross-sectional population-based sample from Czechia included 2,154 25-64 years old subjects (54.6% women). Education was classified as high, middle, and low. Adiposity was assessed as a latent variable based on body fat percentage, BMI, waist circumference, and visceral fat. The mediation potential of unhealthy dietary behavior, alcohol intake, smoking, sedentary behaviors, income, stress, depression, and quality of life was assessed in age-adjusted sex-specific multiple mediation models. RESULTS: The negative direct effect of education on adiposity was statistically significant at 5% level of significance in both sexes. For men, the indirect effect was statistically significant via sedentary behavior (ß = 0.041; 95% CI [0.025-0.062]) with a mediation ratio of 23.7%. In women, the indirect effect was statistically significant via dietary risk (ß = -0.023, 95% CI [-0.037, -0.013]), alcohol intake (ß = -0.006; 95% CI [-0.014, -0.001]), sedentary behavior (ß = 0.012, 95% CI [0.004,0.023]), income (ß = -0.022; 95% CI [-0.041, -0.004]), and mental health (ß = -0.007; 95% CI [-0.019, -0.001]). The total mediation ratio in women was 30.5%. CONCLUSIONS: Sedentary behaviors had mediating role in the association between education and adiposity in both sexes, with more important role in men. In addition, unhealthy diet and lower income partially mediated the educational gradient in adiposity in women.

The diabetes care continuum in Venezuela: Cross-sectional and longitudinal analyses to evaluate engagement and retention in care.

The impact of the humanitarian crisis in Venezuela on care for noncommunicable diseases (NCDs) such as diabetes is unknown. This study aims to document health system performance for diabetes management in Venezuela during the humanitarian crisis. This longitudinal study on NCDs is nationally representative at baseline (2014-2017) and has follow-up (2018-2020) data on 35% of participants. Separate analyses of the baseline population with diabetes (n = 585) and the longitudinal population with diabetes (n = 210) were conducted. Baseline analyses constructed a weighted care continuum: all diabetes; diagnosed; treated; achieved glycaemic control; achieved blood pressure, cholesterol, and glycaemic control; and achieved aforementioned control plus non-smoking. Weighted multinomial regression models controlling for region were used to estimate the association between socio-demographic characteristics and care continuum stage. Longitudinal analyses constructed an unweighted care continuum: all diabetes; diagnosed; treated; and achieved glycaemic control. Unweighted multinomial regression models controlling for region were used to estimate the association between socio-demographic characteristics and changes in care continuum stage. Among 585 participants with diabetes at baseline, 71% were diagnosed, 51% were on treatment, and 32% had achieved glycaemic control. Among 210 participants with diabetes in the longitudinal population, 50 (24%) participants' diabetes management worsened, while 40 (19%) participants improved. Specifically, the proportion of those treated decreased (60% in 2014-2017 to 51% in 2018-2020), while the proportion of participants achieving glycaemic control did not change. Although treatment rates have declined substantially among people with diabetes in Venezuela, management changed less than expected during the crisis.

The Influence of Adiposity Levels on the Relation between Perfluoroalkyl Substances and High Depressive Symptom Scores in Czech Adults.

The extensive use and bioaccumulation of Perfluoroalkyl Substances (PFAS) over time raise concerns about their impact on health, including mental issues such as depression. This study aims to evaluate the association between PFAS and depression. In addition, considering the importance of PFAS as an endocrine disruptor and in adipogenesis, the analyses will also be stratified by body fat status. A cross-sectional study with 479 subjects (56.4% women, 25-89 years) was conducted. Four PFAS were measured: perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), and perfluorooctane sulfonate (PFOS). The Poisson regression model was applied using robust error variances. The fully adjusted model included age, sex, educational level, income, smoking, physical activity, body fat percentage, and the questionnaire to assess depression. The prevalence of depression and high body fat was 7.9% and 41.1%, respectively. Only PFOA was significantly associated with depression in the entire sample (prevalence rate (PR): 1.91; confidence interval (CI95%): 1.01-3.65). However, in the group with normal adiposity, PFOA (3.20, CI95%: 1.46-7.01), PFNA (2.54, CI95%: 1.29-5.00), and PFDA (2.09, CI95%: 1.09-4.00) were also significant. Future research should investigate the role of obesity as well as the biological plausibility and possible mechanisms increasing the limited number of evidences between PFAS and depression.

Impact of the complex humanitarian crisis on the epidemiology of the cardiometabolic risk factors in Venezuela.

BACKGROUND: The complex humanitarian crisis (CHC) in Venezuela is characterized by food insecurity, hyperinflation, insufficient basic services, and the collapse of the healthcare system. The evolution of the epidemiology of cardiometabolic risk factors in this context is unknown. AIM: To compile the last 20 years evidence on the prevalence of cardiometabolic risk factors in adults of Venezuela in the context of the CHC. METHODS: A comprehensive literature review of population-based studies of adults in Venezuela from 2000 to 2020. RESULTS: Seven studies (National EVESCAM 2014-2017, 3 regions VEMSOLS 2006-2010, Maracaibo city 2007-2010, Merida city 2015, Mucuchies city 2009, Barquisimeto city CARMELA 2003-2005, and Zulia state 1999-2001) with samples sizes ranging from 109 to 3414 subjects were included. Over time, apparent decrease was observed in smoking from 21.8% (2003-2005) to 11.7% (2014-2017) and for obesity from 33.3% (2007-2010) to 24.6% (2014-2017). In contrast, there was an apparent increase in diabetes from 6% (2003-2005) to 12.3% (2014-2017), prediabetes 14.6% (2006-2010) to 34.9% (2014-2017), and hypertension 24.7% (2003-2005) to 34.1% (2014-2017). The most prevalent dyslipidemia - a low HDL-cholesterol - remained between 65.3% (1999-2001) and 63.2% (2014-2017). From 2006-2010 to 2014-2017, the high total cholesterol (22.2% vs 19.8%, respectively) and high LDL-cholesterol (23.3% vs 20.5%, respectively) remained similar, but high triglycerides decreased (39.7% vs 22.7%, respectively). Using the same definition across all the studies, metabolic syndrome prevalence increased from 35.6% (2006-2010) to 47.6% (2014-2017). Insufficient physical activity remained steady from 2007-2010 (34.3%) to 2014-2017 (35.2%). CONCLUSION: Changes in the prevalence of cardiometabolic risk factors in Venezuela are heterogeneous and can be affected by various social determinants of health. Though the Venezuelan healthcare system has not successfully adapted, the dynamics and repercussions of the CHC on population-based cardiometabolic care can be instructive for other at-risk populations.

Optimal waist circumference cutoff values to predict cardiometabolic alterations in a Venezuela national representative sample. The EVESCAM study / Valores óptimos de punto de corte de circunferencia abdominal para predecir alteraciones cardiometabólicas en una muestra representativa nacional de Venezuela. El estudio EVESCAM

Abstract Objective: Waist circumference (WC) value reflects abdominal adiposity, but the amount abdominal fat that is associated to cardiometabolic risk factors varies among ethnicities. Determination of metabolic abnormalities has not undergone a WC adaptation process in Venezuela. The aim of the study was (1) to determine the optimal WC cutoff value associated with ≥2 cardiometabolic alterations and (2) incorporating this new WC cutoff, to determine the prevalence of abdominal obesity and cardiometabolic risk factors related in Venezuela. Methods: The study was national population-based, cross-sectional, and randomized sample, from 2014 to 2017. To assess performance of WC for identifying cardiometabolic alterations, receiver operating characteristics curves, area under the curve (AUC), sensitivity, specificity, and positive likelihood ratios were calculated. Results: Three thousand three hundred eighty-seven adults were evaluated with mean age of 41.2 ± 15.8 years. Using the best tradeoff between sensitivity and specificity, WC cutoffs of 90 cm in men (sensitivity = 72.4% and specificity = 66.1%) and 86 cm in women (sensitivity = 76.2% and specificity = 61.4%) were optimal for aggregation of ≥2 cardiometabolic alterations. AUC was 0.75 in men and 0.73 in women using these new cutoffs. Prevalence of abdominal obesity and metabolic syndrome was 59.6% (95 CI; 57.5-61.7) and 47.6% (95 CI; 45.2-50.0), respectively. Cardiometabolic risk factors were associated with being men, higher age, adiposity, and living in northern or western regions. Conclusion: The optimal WC values associated with cardiometabolic alterations were 90 cm in men and 86 cm in women. More than half of the Venezuelan population had abdominal obesity incorporating this new WC cutoff.

Resumen Objetivo: El valor de la circunferencia abdominal (CA) refleja la adiposidad abdominal, pero la cantidad de grasa abdominal asociada a factores de riesgo cardiometabólicos varía según la etnia. La determinación de anomalías metabólicas no se ha adaptado a la CA en Venezuela. 1) Detrerminar el valor de corte óptimo de CA asociados a ≥ 2 alteraciones cardiometabólicas. 2) Incorporando este nuevo límite de CA, determinar la prevalencia de obesidad abdominal y factores de riesgo cardiometabólicos relacionados en Venezuela. Métodos: Fue un estudio poblacional, transversal, de muestreo aleatorio de 2014 a 2017. Para evaluar el valor de CA para identificar alteraciones cardiometabólicas, se realizaron curvas características operativa del receptor y se calculó área bajo la curva (ABC), sensibilidad, especificidad y razón de similitud. Resultados: se evaluaron 3387 adultos con una edad promedio de 41.2 ± 15.8 años. Utilizando la mejor relación entre sensibilidad y especificidad, se determinó que los valores de corte de 90 cm en hombres (sensibilidad = 72.4% y especificidad = 66.1%) y 86 cm en mujeres (sensibilidad = 76.2% y especificidad = 61.4%) fueron óptimos para la agregación de ≥ 2 alteraciones cardiometabólicas. El ABC fue de 0,75 en hombres y de 0,73 en mujeres usando estos nuevos puntos de corte. La prevalencia de obesidad abdominal y síndrome metabólico fue 59.6% (95IC; 57.5 - 61.7) y 47.6% (95CI; 45.2 - 50.0), respectivamente. La presencia de factores de riesgo cardiometabólicos se asoció con ser hombre, mayor edad, adiposidad y vivir en regiones del norte o del oeste. Conclusión: Los valores óptimos de CA asociados con alteraciones cardiometabólicas fueron 90 cm en hombres y 86 cm en mujeres. Más de la mitad de la población venezolana tenía obesidad abdominal al incorporar este nuevo corte de CA.

The Prevalence of Dysglycemia-Based Chronic Disease in a European Population - a New Paradigm to Address Diabetes Burden: A Kardiovize Study.

OBJECTIVE: To determine the prevalence rate and associated risk factors for each stage of the Dysglycemia-Based Chronic Disease (DBCD) model, which 4 distinct stages and prompts early prevention to avert Diabetes and cardiometabolic complications. METHODS: Subjects between 25 and 64 years old from a random population-based sample were evaluated in Czechia from 2013 to 2014 using a cross-sectional design. DBCD stages were: stage 1 "insulin resistance" (inferred risk from abdominal obesity or a family history of diabetes); stage 2 "prediabetes"(fasting glucose between 5.6 and 6.9 mmol/L); stage 3 "type 2 diabetes (T2D)" (self-report of T2D or fasting glucose ≥7 mmol/L); and stage 4 "vascular complications" (T2D with cardiovascular disease). RESULTS: A total of 2147 subjects were included (57.8% women) with a median age of 48 years. The prevalence of each DBCD stage were as follows: 54.2% (stage 1); 10.3% (stage 2), 3.7% (stage 3); and 1.2% (stage 4). Stages 2 to 4 were more frequent in men and stage 1 in women (P < .001). Using binary logistic regression analysis adjusting by age/sex, all DBCD stages were strongly associated with abnormal adiposity, hypertension, dyslipidemia, and smoking status. Subjects with lower educational levels and lower income were more likely to present DBCD. CONCLUSION: Using the new DBCD framework and available metrics, 69.4% of the population had DBCD, identifying far more people at risk than a simple prevalence rate for T2D (9.2% in Czechia, 2013-2014). All stages were associated with traditional cardiometabolic risk factors, implicating common pathophysiologic mechanisms and a potential for early preventive care. The social determinants of health were related with all DBCD stages in alarming proportions and will need to be further studied.

Cardiometabolic risk factors in Venezuela. The EVESCAM study: a national cross-sectional survey in adults.

BACKGROUND: No previous study in Venezuela and few in the Region of the Americas have reported national cardiometabolic health data. OBJECTIVES: To determine the prevalence and distribution of cardiometabolic risk factors (CMRF) in adults of Venezuela. METHODS: A population-based, cross-sectional, and randomized cluster sampling national study was designed to recruit 4454 adults with 20 years or older from the eight regions of the country from July 2014 to January 2017. Sociodemographic, clinical, physical activity, nutritional, and psychological questionnaires; anthropometrics, blood pressure, and biochemical measurements were obtained. The results were weighted by gender, age, and regions. RESULTS: Data from 3414 participants (77% of recruited), 52.2% female, mean age of 41.2 ± 15.8 years, were analyzed. CMRF adjusted-prevalence were: diabetes (12.3%), prediabetes (34.9%), hypertension (34.1%), obesity (24.6%), overweight (34.4%), abdominal obesity (47.6%), underweight (4.4%), hypercholesterolemia (19.8%), hypertriglyceridemia (22.7%), low HDL-cholesterol (63.2%), high LDL-c (20.5%), daily consumption of fruits (20.9%) and vegetables (30.0%), insufficient physical activity (35.2%), anxiety (14.6%) and depression (3.2%) symptoms, current smoker (11.7%), and high (≥ 20%) 10-year fatal cardiovascular risk (14.0%). CMRF prevalence varied according to gender, age and region of residence. CONCLUSIONS: Cardiometabolic risk factors are highly prevalent in Venezuelan adults. This situation can be affected by the severe socio-economic crisis in the country. The joint action of different stakeholders to implement public health strategies for the prevention and treatment of these risk factors in Venezuela is urgently needed.

Roles for community health workers in diabetes prevention and management in low- and middle-income countries / O papel dos agentes comunitários de saúde na prevenção e manejo do diabetes em países de renda baixa e média / Roles de trabajadores comunitarios en salud para la prevención y gestión de la diabetes en países con medios y bajos ingresos

Diabetes prevalence is increasing worldwide, especially in low- and middle-income countries (LMIC), posing the need for improved detection and management strategies. Chronic disease models and lifestyle medicine provide structures for action. Community health workers (CHWs) can significantly contribute to chronic disease care if they are trained and integrated into low-resource health systems. Although most current CHWs worldwide are performing maternal/child health and infectious disease-related tasks, other programs involving CHWs for noncommunicable disease prevention and management are increasing. In this article, we discuss the advantages, challenges, and questions regarding possible roles assigned to CHWs in the prevention and management of diabetes. These roles include performing simple screening tests, implementing lifestyle/behavioral interventions, and connecting patients with alternatives to biomedicine. Specifically, CHWs can aid diabetes epidemiological surveillance by conducting risk score-based screening or capillary glucose testing, and they can facilitate diabetes self-management by delivering interventions described in the transcultural diabetes nutrition algorithm. Furthermore, while this role has not formally been assigned, CHWs can leverage their intimate knowledge of local practices to provide decision-making support to patients in environments with pluralistic health systems. Ethnocultural differences in CHW functions and transcultural adaptations of their roles in diabetes care should also be considered. In summary, CHWs can improve diabetes care by screening high-risk individuals and implementing lifestyle interventions, especially in LMIC.

A prevalência do diabetes está aumentando em nível global, sobretudo nos países de renda baixa e média, o que exige melhor detecção e manejo da doença. O modelo de doenças crônicas e a medicina de estilo de vida fornecem estruturas para a ação nesse sentido. Os agentes comunitários de saúde (ACS) podem contribuir de maneira significativa para a assistência às doenças crônicas, desde que sejam capacitados e integrados aos sistemas de saúde, que dispõem de recursos limitados. Embora a maioria dos ACS no mundo esteja desempenhando tarefas relacionadas à saúde materno-infantil e doenças infecciosas, estão crescendo outros programas que envolvem a prevenção e manejo das doenças não transmissíveis. O artigo discute as vantagens, desafios e questões relacionados aos possíveis papéis definidos para os ACS na prevenção e manejo do diabetes. Esses papéis incluem testes simples de triagem, implementação de intervenções comportamentais e de estilo de vida e recomendação de alternativas à biomedicina para os pacientes. Especificamente, os ACS podem auxiliar na vigilância epidemiológica do diabetes, realizando triagem baseada em pontuação de risco ou testagem de glicemia capilar, e podem facilitar o auto-manejo do diabetes através de intervenções baseadas no algoritmo nutricional transcultural do diabetes. Além disso, embora o papel não tenha sido definido formalmente, os ACS podem alavancar seu conhecimento íntimo das práticas locais para apoiar decisões pelos pacientes em contextos com sistemas de saúde pluralistas. Devem ser consideradas as diferenças etnoculturais nas funções dos ACS e nas adaptações transculturais de seus papéis durante a assistência ao diabetes. Em resumo, os ACS podem melhorar a assistência ao diabetes através da triagem e da implementação oportuna de intervenções de estilo de vida, principalmente nos países de renda baixa e média.

La prevalencia de diabetes está aumentando en todo el mundo, especialmente en los países de bajos y medios ingresos (LMIC por sus siglas en inglés), imponiendo la necesidad de una detección y gestión mejoradas. Un modelo de enfermedad crónica y la medicina del estilo de vida proporcionan estructuras para la acción. Los trabajadores comunitarios de salud (CHWs por sus siglas en inglés) pueden contribuir significativamente al cuidado de la enfermedad crónica, si son entrenados e integrados en sistemas con pocos recursos de salud. A pesar de que la mayoría de los actuales CHWs en todo el mundo están desarrollando tareas relacionadas con enfermedades infecciosas en la salud maternal/infantil, otros programas que implican a los CHWs para la prevención y gestión de enfermedades no comunicables están aumentando. En este artículo, discutimos las ventajas, desafíos, y preguntas respecto a los posibles roles asignados a los CHWs, en la prevención y gestión de la diabetes. Estos roles incluyen realizar simples pruebas de detección, implementando intervenciones de estilo de vida/comportamentales, y conectando pacientes con alternativas a la biomedicina. Específicamente, los CHWs pueden ayudar en la vigilancia epidemiológica de la diabetes, llevando a cabo pruebas de detección basadas en marcadores de riesgo o pruebas de glucosa capilares, y pueden facilitar el autocontrol de la diabetes proporcionando intervenciones descritas en el algoritmo transcultural de nutrición en diabetes. Asimismo, mientras este rol no se les haya asignado formalmente, los CHWs pueden potenciar su conocimiento profundo de prácticas locales para proporcionar apoyo en la toma de decisiones a pacientes en entornos con sistemas de salud plurales. Las diferencias etnoculturales en las funciones de los CHW y las adaptaciones transculturales de sus papeles en el cuidado de la diabetes deberían también ser consideradas. En resumen, los CHWs pueden mejorar el cuidado de la diabetes detectando e implementando oportunamente las intervenciones de estilo de vida, especialmente en LMIC.

Associations between high triglycerides and arterial stiffness in a population-based sample: Kardiovize Brno 2030 study.

BACKGROUND: The term arterial stiffness (ArSt) describes structural changes in arterial wall related to the loss of elasticity and is known as an independent predictor of cardiovascular diseases (CVD). The evidence relating to ArSt and triglycerides (TG) shows contradictory results. This paper means to survey the association between high TG and ArSt, utilizing the cardio-ankle vascular index (CAVI). METHODS: Subjects aged between 25 and 64 years from a random population-based sample were evaluated between 2013 and 2016. Data from questionnaires, blood pressure, anthropometric measures, and blood samples were collected and analyzed. CAVI was measured using VaSera VS-1500 N devise. Subjects with a history of CVD or chronic renal disease were excluded. RESULTS: One thousand nine hundred thirty-four participants, 44.7% of males, were included. The median age was 48 (Interquartile Range [IQR] 19) years, TG levels were 1.05 (0.793) mmol/L, and CAVI 7.24 (1.43) points. Prevalence of high CAVI was 10.0% (14.5% in males and 6.4% in females; P <  0.001) and prevalence of hypertriglyceridemia was 20.2% (29.2% in males and 13% in females, P <  0.001). The correlation between TG and CAVI was 0.136 (P <  0.001). High CAVI values were more prevalent among participants with metabolic syndrome (MetS), high blood pressure, dysglycemia, abdominal obesity, high LDL-cholesterol (LDL-c), and high total cholesterol. Using binary regression analysis, high TG were associated with high CAVI, even after adjustment for other MetS components, age, gender, smoking status, LDL-c, and statin treatment (ß = 0.474, OR = 1.607, 95% CI = 1.063-2.429, P = 0.024). CONCLUSION: TG levels were correlated with ArSt, measured as CAVI. High TG was associated with high CAVI independent of multiple cardiometabolic risk factors. Awareness of the risks and targeted treatment of hypertriglyceridemia could further benefit in reducing the prevalence of CVD and events.

Cardiovascular Health in a National Sample of Venezuelan Subjects Assessed According to the AHA Score: The EVESCAM.

BACKGROUND: Cardiovascular health status of the Venezuelan population has not been evaluated. The American Heart Association recommends the Cardiovascular Health Score (CHS) to assess cardiovascular health. OBJECTIVES: This study sought to determine the prevalence of CHS categories in a nationally representative sample of Venezuelan adults. METHODS: EVESCAM (Venezuelan Study of Cardio-Metabolic Health) was a national population-based, cross-sectional, randomized cluster sampling study performed from July 1, 2014 to January 31, 2017, which assessed 3,454 adults, age ≥20 years, with a response rate of 77.3%. The American Heart Association's CHS evaluates 4 behaviors (smoking, body mass index, physical activity, and diet) and 3 risk factors (total cholesterol, blood pressure, and blood glucose), assigning 1 point to those meting an ideal behavior or factor or 0 points if are not. Subjects were categorized as having ideal (5 to 7 points), intermediate (3 to 4), or poor (<3) cardiovascular health. Weighted prevalence by age, sex, and regions are presented. RESULTS: A total of 2,992 participants completed the data. Mean age and CHS were 41.4 ± 15.8 years and 4.3 ± 1.1 points, respectively. The prevalence of ideal CHS was 37.9% (95% confidence interval: 35.0 to 40.7); two-thirds presented with intermediate to poor CHS. Ideal CHS was most prevalent in women, in the youngest participants, and in those with higher education degree and living in a rural area. The prevalence of 7 components was 0.13%. Subjects evaluated since mid-2016 had a higher prevalence of ideal CHS (≈47%) than those evaluated before it (≈32%) (p < 0.001). CONCLUSIONS: A high prevalence of ideal CHS was observed in Venezuelan adults compared with other reports; however, a large proportion remain with high risk for cardiovascular disease.

Prevalence of metabolic syndrome in three regions in Venezuela: The VEMSOLS Study / Prevalência de síndrome metabólica em três regiões da Venezuela: o estudo VemSOLS

Background: No previous study has evaluated the prevalence of metabolic syndrome (MS) in more than one region in Venezuela.Objective: To determine the prevalence of MS in three Venezuelan regions. Methods: From 2006 to 2010, a total of 1,320 subjects aged ≥ 20 years were selected by multistage stratified random sampling from the regions of Lara State (western region), Mérida State (the Andean region), and Capital District (Capital Region). Anthropometric measurements, blood pressure, and biochemical analysis were obtained from each participant. MS was defined according to the harmonized Joint Interim Statement (2009) definition.Results: Mean age was 44.8 ± 0.39 years and 68.5% of the participants were female. The overall prevalence of MS was 35.7% (95% confidence interval 32.2 ­ 39.2%), while the prevalence was 42.5% (95% CI 38.8 ­ 46.1%) among men and 32.6% (95% CI 29.1 ­ 36.0%) among women (p < 0.001). In women, the prevalence of MS increased at almost every decade of life, while in men, the prevalence was similar from the age of 30 years onwards. The most prevalent abnormalities were low HDL-c levels (58.6%, 95% CI 54.9 ­ 62.1%), abdominal obesity (52.0%, 95% CI 48.4 ­ 55.7%), and elevated triglycerides levels (39.7%, 95% CI 36.1 ­ 43.2%). The prevalence of MS increased with increasing body mass index categories. Conclusion: In Venezuela, MS is a highly prevalent condition, which increases the risk of type 2 diabetes and cardiovascular disease in a large number of subjects

Prevalence of Dyslipidemias in Three Regions in Venezuela: The VEMSOLS Study Results / Prevalência de Dislipidemias em Três Regiões na Venezuela: Resultados do Estudo VEMSOLS

Abstract Background: The prevalence of dyslipidemia in multiple regions of Venezuela is unknown. The Venezuelan Metabolic Syndrome, Obesity and Lifestyle Study (VEMSOLS) was undertaken to evaluate cardiometabolic risk factors in Venezuela. Objective: To determine the prevalence of dyslipidemia in five populations from three regions of Venezuela. Methods: During the years 2006 to 2010, 1320 subjects aged 20 years or older were selected by multistage stratified random sampling from all households in five municipalities from 3 regions of Venezuela: Lara State (Western region), Merida State (Andean region), and Capital District (Capital region). Anthropometric measurements and biochemical analysis were obtained from each participant. Dyslipidemia was defined according to the NCEP/ATPIII definitions. Results: Mean age was 44.8 ± 0.39 years and 68.5% were females. The prevalence of lipids abnormalities related to the metabolic syndrome (low HDL-c [58.6%; 95% CI 54.9 - 62.1] and elevated triglycerides [39.7%; 36.1 - 43.2]) were the most prevalent lipid alterations, followed by atherogenic dyslipidemia (25.9%; 22.7 - 29.1), elevated LDL-c (23.3%; 20.2 - 26.4), hypercholesterolemia (22.2%; 19.2 - 25.2), and mix dyslipidemia (8.9%; 6.8 - 11.0). Dyslipidemia was more prevalent with increasing body mass index. Conclusion: Dyslipidemias are prevalent cardiometabolic risk factors in Venezuela. Among these, a higher prevalence of low HDL is a condition also consistently reported in Latin America.

Resumo Fundamento: A prevalência de dislipidemia em várias regiões da Venezuela é desconhecida. A Síndrome Metabólica venezuelana, Obesidade e Estilo de Vida Estudo (VEMSOLS) foram realizados para avaliar os fatores de risco cardiometabólico na Venezuela. Objetivo: Determinar a prevalência de dislipidemia em cinco populações de três regiões da Venezuela. Métodos: Durante os anos de 2006 a 2010, 1320 indivíduos com 20 anos ou mais foram selecionados por amostragem aleatória estratificada de vários estágios de todas as famílias em cinco municípios a partir de 3 regiões da Venezuela: Estado Lara (região Oeste), Estado de Mérida (região andina) e Capital Distrito (região Capital). medidas antropométricas e análise bioquímica foram obtidas de cada participante. Dislipidemia foi definida de acordo com as definições NCEP / ATPIII. Resultados: A idade média foi de 44,8 ± 0,39 anos, e 68,5% eram do sexo feminino. A prevalência de lípidos anormalidades relacionadas à síndrome metabólica (HDL-c baixo [58,6%; IC95% 54,9-62,1] e triglicerídeos elevados [39,7%; 36,1-43,2]) foram as alterações lipídicas mais prevalente, seguida pela dislipidemia aterogênica ( 25,9%; 22,7-29,1), LDL-C elevado (23,3%; 20,2-26,4), hipercolesterolêmica (22,2%; 19,2-25,2), e misturar dislipidemia (8,9%; 6,8-11,0). Dislipidemia foi mais prevalente com o aumento do índice de massa corporal. Conclusão: As dislipidemias são fatores de risco cardiometabólico prevalentes na Venezuela. Entre elas, uma maior prevalência de baixo HDL é uma condição também consistentemente relatada na América Latina.

Prevalencia de dislipidemias en la región capital: resultados preliminares del estudio EVESCAM / Prevalence of dyslipidemias in the capital region: preliminary results of the EVESCAM study

Las dislipidemias son un factor de riesgo para enfermedades cardiovasculares. Se desconoce la prevalencia actual de dislipidemias en la región Capital de Venezuela. Objetivo: Determinar la prevalencia de dislipidemias en adultos de la región capital evaluados en el estudio EVESCAM. Métodos: Estudio poblacional, observacional, transversal de muestreo aleatorio poliestratificado por conglomerados. Se evaluaron 7 comunidades de la Región Capital desde julio de 2015 hasta enero de 2016: El Retiro; Miranda Casco Central y Bello Campo; Los Teques: La Cima; Guatire: Centro y Castillejo y rural: Guatire: La Candelaria. Participaron 416 sujetos desde los 20 años de edad. Los puntos de corte para definir las dislipidemias fueron hipoalfalipoproteinemia: colesterol HDL < 40 mg/dL; hipertrigliceridemia: triglicéridos (TG) ≥ 150 mg/dL; hipercolesterolemia: colesterol total ≥ 200 mg/dL; colesterol LDL elevado: colesterol LDL ≥ de 130 mg/dL; dislipidemia aterogénica: TG ≥ 150 mg/dL más colesterol HDL bajo (mujeres: < 40 mg/dl y hombres: < 50 mg/dl). Las frecuencias se expresaron en porcentajes y se aplicó el estadístico Chi cuadrado, un valor de p < 0,05 fue considerado como estadísticamente significativo. Resultados: La dislipidemia con mayor prevalencia fue la hipoalfalipoproteinemia (67.1%) seguida de la LDLc elevada (20%), hipercolesterolemia (17,1%), hipertrigliceridemia (12,0%) y por último dislipidemia aterogenica (9,4%). La hipoalfalipoproteinemia, fue mayor en hombres que en mujeres (81,6% y 60,8%; respectivamente, p < 0,001) presentándose con mayor prevalencia en el grupo etario de 20 a 40 años al contrario del resto de las dislipidemias. Conclusión: La hipoalfalipoproteinemia persiste como la dislipidemia más prevalente de la región(AU)

Dyslipidemias are a risk factor for cardiovascular diseases. The current prevalence of dyslipidemias in the Capital Region of Venezuela is unknown. Objective: To determine the prevalence of dyslipidemias in adults from the capital region of Venezuela evaluated in the EVESCAM study. Methods: apopulation based, observational, cross-sectional, and cluster sampling study was desing. Seven communities from the Capital Region were evaluated from July 2015 to January 2016: El Retiro; Miranda- Chacao: Casco Central y Bello Campo; Los Teques: La Cima; Guatire: Centro y Castillejo y Rural: Guatire: Candelaria. 416 subjects were included. Dyslipidemias was define as hypoalphalipoproteinemia: HDL cholesterol <40 mg/ dL; hypertriglyceridemia: triglycerides ≥ 150 mg/dL; hypercholesterolemia: total cholesterol ≥ 200 mg/dL; High LDL cholesterol: ≥ 130 mg/dL; therogenic dyslipidemia: triglycerides ≥ 150 mg / dL and low HDL cholesterol (women: <40 mg / dl and men: <50 mg / dl). The frequencies were expressed as percentages and Chi-square test was applied to assess differences. The level of statistical significance accepted was a p-value < 0.05. Results: The most prevalent dyslipidemia was hypoalphalipoproteinemia (67.1%) followed by elevated LDLc (20%), hypercholesterolemia (17.1%), hypertriglyceridemia (12.0%), and atherogenic dyslipidemia (9.4%). Hypoalphalipoproteinemia was higher in men than women (81.6% and 60.8%, respectively, p <0.001), with a higher prevalence at the age group of 20 to 40 years, unlike the rest of dyslipidemias. Conclusion: The hypoalphalipoproteinemia persists as the most prevalent dyslipidemia in the region(AU)

Transculturalizing Diabetes Prevention in Latin America.

BACKGROUND: Type 2 diabetes (T2D) imposes a heavy burden in developing countries, requiring effective primary prevention policies. Randomized clinical trials have identified successful strategies in T2D prevention. However, translating these results to real-life scenarios and adapting to ethnocultural differences is a major challenge. Transculturalization allows incorporating cultural factors to diabetes prevention strategies to optimize implementation of clinical trials results. The purpose of this paper is to review the transcultural adaptations developed for T2D prevention in Latin America (LA). METHODS: A comprehensive literature review spanning 1960-2016 was performed, using "Diabetes," "Latin America," "Prevention," "Screening," and "Tools" as key words. RESULTS: Two major tasks are underway in LA: adaptation of screening tools for high-risk individuals, and implementation of diabetes prevention programs. The Finnish Diabetes Risk Score (FINDRISC) is the most widely used screening tool to detect new cases of T2D and people with prediabetes, and it has been adapted (LA-FINDRISC) to include the waist circumference cutoff values appropriate for LA population (≥94 cm for men and ≥90 cm for women). The validation of the LA-FINDRISC performance depends on the local characteristics. A LA-FINDRISC score >10 may be the best cutoff to identify individuals with impaired glucose regulation in population-based studies, but a higher score (>12-14) might be more appropriate in a clinical setting. A shorter version of the FINDRISC using only the 4 variables with highest impact has been developed and validated in Colombia (ColDRISC). The translation of the Diabetes Prevention Program study in a Latino population in Venezuela found a significant improvement in cardiometabolic risk factors. An adaptation of the Diabetes Prevention Study in the DEMOJUAN study in Barranquilla, Colombia, reduced 2-hour postload glucose. CONCLUSION: Successful transculturalization strategies have been implemented in screening tools and prevention programs in LA.

Chimo, a smokeless tobacco preparation, is associated with a higher frequency of type 2 diabetes / Chimó, una preparación de tabaco sin humo, está asociada con una elevada frecuencia de diabetes mellitus tipo 2

The relationship between smokeless tobacco (ST) use and type-2 diabetes (T2D) has only been reported in Swedish men, though with contradictory results. In Venezuela, chimó is the most common ST preparation. The relationship between chimó and T2D in Venezuela is unknown. The objective of the study was to evaluate the relationship between chimó use and T2D in a population with high prevalence of ST use in the Andes region of Venezuela. An observational, cross-sectional, correlational study was designed. During 2013-2014, 759 consecutive subjects aged 20 years or older were evaluated in a medical center. Anthropometric measurements and responses to a standard questionnaire were obtained. Blood glucose and lipid concentrations were measured. The mean age was 53.1 years, 58% were female, and 24.1% reported ST use. ST use was more frequent in men than women (32.9% vs. 17.7%; p < 0.001). ST users showed lower body mass index (BMI), body fat and total cholesterol, but a higher frequency of T2D, than non-ST users. Logistic regression analysis, adjusted by age, family history of T2D, and hypertriglyceridemia, demonstrated that ST use was associated with an increased odd for T2D by 77% (OR 1.77; 95% CI 1.15 - 2.72) among ST-users. In conclusion, chimó, a ST form frequently used in the Andes region of Venezuela, is associated with a higher frequency of T2D and lower fat mass. Implications of these findings are discussed.

La relación entre el uso de tabaco no inhalado (TBNI) y la diabetes mellitus tipo 2 (DM2) ha sido únicamente reportada en hombres de Suecia, con resultados contradictorios. En Venezuela, el chimó es la preparación más común de TBNI. La relación entre el chimó y la DM2 en Venezuela es desconocida. El objetivo de este estudio fue evaluar la relación entre el uso de chimó y la DM2 en una población con elevada prevalencia de uso de TBNI en la región de los Andes de Venezuela. Se diseñó un estudio observacional, transversal, tipo correlacional. Durante 2013-2014, 759 sujetos de 20 o más años fueron evaluados de forma consecutiva en un centro médico. La edad promedio fue 53,1 años, 58% fueron mujeres y 24,1% reportó uso de TBNI. El uso de TBNI fue más frecuente en hombres que en mujeres (32,9% vs. 17,7%; p < 0,001). Los consumidores de TBNI mostraron menor índice de masa corporal (IMC), grasa corporal y colesterol total, pero mayor frecuencia de DM2 que los no consumidores de TBNI. El análisis de regresión logística ajustado por edad, historia familiar de DM2 e hipertrigliceridemia, demostró que el uso de TBNI se asoció con un incremento de 77% de probabilidad de presentar DM2 (OR 1,77; 95% CI 1,15 - 2,72). En conclusión, el chimó, una forma de TBNI frecuentemente usada en la región de los Andes de Venezuela, está asociada con una mayor frecuencia de DM2 y con una menor masa grasa. Se discuten las implicaciones de este hallazgo.

O Chimó, uma Preparação de Tabaco sem Fumaça, está Associado a uma Frequência mais Baixa de Hipertensão em Indivíduos com Diabetes Tipo 2 / Chimó, a Smokeless Tobacco Preparation, is Associated With a Lower Frequency of Hypertension in Subjects with Type 2 Diabetes

Fundamentos: O uso do tabaco e a hipertensão arterial sistêmica (HAS) são as principais causas preveníveis de morte a nível global. O tabaco é apresentado nas formas com ou sem fumaça (TSF). O uso do TSF tem sido relacionado à doença cardiovascular, diabetes tipo 2 (DM2) e câncer. Na Venezuela, o chimó é a preparação de TSF mais comum e a sua relação com a HAS é desconhecida. Objetivo: Avaliar a relação entre o uso de chimó e HAS em uma população com alta prevalência de uso de TSF na Venezuela. Métodos: Entre 2013-2014, um total de 1.938 indivíduos com 20 anos ou mais foram avaliados consecutivamente em um centro médico. Foram obtidas medidas antropométricas e de pressão arterial (PA), além de respostas a um questionário padrão. Resultados: Os participantes tinham uma média de idade de 49,2 anos, 59,5% eram do sexo feminino, 38,9% apresentavam HAS, 23,2% relataram uso de TSF e 11,6% relataram ter DM2. Um terço dos indivíduos com DM2 eram usuários de TSF, e este grupo mostrou valores mais baixos de frequência cardíaca, PA sistólica, índice de massa corporal (IMC) e frequência de HAS quando comparado a sujeitos com DM2 não usuários de TSF (p < 0,05). Em indivíduos com DM2 com 50 anos ou mais, o uso de TSF foi associado a uma frequência 69% mais baixa de HAS quando comparados a indivíduos que não usavam TSF. Em regressão logística ajustada pela frequência cardíaca, idade, ocorrência de DM2, sobrepeso/obesidade e história familiar de HAS, o uso de TSF esteve associado a uma frequência 30% mais baixa de HAS (razão de chances 0,70; intervalo de confiança de 95% 0,55 - 0,90). Conclusão: O chimó, um TSF frequentemente utilizado na região dos Andes na Venezuela, está associado a valores mais baixos de PA, frequência cardíaca, IMC e frequência mais baixa de HAS em indivíduos com DM2 com mais de 50 anos. Esta associação contraintuitiva negativa entre o chimó e alguns fatores de risco cardiometabólicos realça o caráter complexo destas relações e a necessidade de estudos adicionais

Background: Tobacco use and hypertension are leading preventable causes of death globally. Tobacco is presented as smoked or smokeless tobacco (ST). ST use has been related to cardiovascular disease, type 2 diabetes (T2D), and cancer. In Venezuela, chimó is the most common ST preparation, and its relationship with hypertension is unknown. Objective: To evaluate the relationship between chimó use and hypertension in a population with a high prevalence of ST use in Venezuela. Methods: From 2013-2014, a total of 1,938 consecutive subjects aged 20 years or older were evaluated in a medical center. Anthropometrics and blood pressure (BP) measurements, and responses to a standard questionnaire were obtained. Results: The participants had a mean age of 49.2 years, 59.5% were female, 38.9% had hypertension, 23.2% reported ST use, and 11.6% reported having T2D. One-third of the subjects with T2D were ST users, and this group showed lower heart rate, systolic BP, body mass index (BMI), and frequency of hypertension when compared with T2D subjects who were not ST users (p < 0.05). In subjects with T2D who were 50 years or older, ST use was associated with a 69% lower frequency of hypertension when compared with subjects without ST use. On logistic regression adjusted by heart rate, age, occurrence of T2D, overweight/obesity, and family history of hypertension, ST use was associated with a 30% lower frequency of hypertension (odds ratio 0.70; 95% confidence interval 0.55 ­ 0.90). Conclusion: Chimó, a ST frequently used in the Andes region of Venezuela, is associated with lower BP, heart rate, BMI, and frequency of hypertension in subjects with T2D older than 50 years. This counter-intuitive negative association of chimó with some cardiometabolic risk factors highlights the complex nature of these relationships and the need for further studies
