Prevalence and factors associated with unhealthy metabolic status according to body mass index: analysis of a national nutritional survey.

INTRODUCTION: Although obesity substantially influences public health owing to related comorbidities, it has been discovered that the incidence of such issues is not directly related to obesity but to the patient's unhealthy metabolic status (MUS) independent of the body mass index (BMI). OBJECTIVES: To describe the prevalence of UMS overall and according to BMI and determine the factors associated with it. METHODS: A cross-sectional analytical study was used based on the analysis of secondary databases called the Life Stage Nutritional Surveillance Survey (VIANEV). Participants were selected in two stages, finally obtaining 885 participants. UMS was defined based on the criteria of the Adult Treatment Panel III used to define metabolic status in a set of 5 parameters, if the subject presented two or more alterations it was considered UMS. Six groups were formed according to BMI: metabolically healthy, average weight (MHNW) and unhealthy (MUNW), metabolically healthy, overweight (MHOW) and unhealthy (MUOW), metabolically healthy, obese (MHO) and unhealthy (MUO).). RESULTS: The total prevalence of UMS was 73.11%, with MUNW, MUOW, and MUO being 47.90%, 80.34%, and 96.44%, respectively. Only 5.31% did not present any metabolic alteration. The multivariable analysis found variations globally according to sex, age, marital status, geographical region, smoking habit, and altitude. CONCLUSIONS: A high prevalence of UMS was observed in Peru, indicating that BMI alone is not a sufficient indicator of metabolic status. These findings suggest that strategies should be prioritized to address the growing problem of UMS, considering the particularities of each subpopulation and using a multifaceted approach that addresses modifiable and non-modifiable risk factors.

Factors Associated with Symptoms of Depression among People with Obesity: Analysis of a 3-Year-Peruvian National Survey.

INTRODUCTION: Obesity and depression contribute to the global burden of economic cost, morbidity, and mortality. Nevertheless, not all people with obesity develop depression. OBJECTIVE: To determine the factors associated with depressive symptoms among people aged 15 or older with obesity from the National Demographic and Family Health Survey (ENDES in Spanish 2019-2021). METHODS: Cross-sectional analytical study. The outcome of interest was the presence of depressive symptoms, assessed using the Patient Health Questionnaire-9 (PHQ-9). Crude (cPR) and adjusted (aPR) prevalence ratios were estimated using GLM Poisson distribution with robust variance estimates. RESULTS: The prevalence of depression symptoms was 6.97%. In the multivariate analysis, a statistically significant association was found between depressive symptoms and female sex (PRa: 2.59; 95% CI 1.95-3.43); mountain region (PRa: 1.51; 95% CI 1.18-1.92); wealth index poor (PRa: 1.37; 95% CI 1.05-1.79, medium (PRa: 1.49; 95% CI 1.11-2.02), and rich (PRa: 1.65; 95% CI 1.21-2.26); daily tobacco use (PRa: 2.05, 95% CI 1.09-3.87); physical disability (PRa: 1.96, 95% CI 1.07-3.57); and a history of arterial hypertension (PRa: 2.05; 95% CI 1.63-2.55). CONCLUSION: There are several sociodemographic factors (such as being female and living in the Andean region) and individual factors (daily use of tobacco and history of hypertension) associated with depressive symptoms in Peruvian inhabitants aged 15 or older with obesity. In this study, the COVID-19 pandemic was associated with an increase in depressive symptoms.

The Fruit Intake-Adiposity Paradox: Findings from a Peruvian Cross-Sectional Study.

Due to the increase in obesity worldwide, international organizations have promoted the adoption of a healthy lifestyle, as part of which fruit consumption stands out. However, there are controversies regarding the role of fruit consumption in mitigating this disease. The objective of the present study was to analyze the association between fruit intake and body mass index (BMI) and waist circumference (WC) in a representative sample of Peruvians. This is an analytical cross-sectional study. Secondary data analysis was conducted using information from the Demographic and Health Survey of Peru (2019-2021). The outcome variables were BMI and WC. The exploratory variable was fruit intake, which was expressed in three different presentations: portion, salad, and juice. A generalized linear model of the Gaussian family and identity link function were performed to obtain the crude and adjusted beta coefficients. A total of 98,741 subjects were included in the study. Females comprised 54.4% of the sample. In the multivariate analysis, for each serving of fruit intake, the BMI decreased by 0.15 kg/m2 (ß = -0.15; 95% CI -0.24 to -0.07), while the WC was reduced by 0.40 cm (ß = -0.40; 95% CI -0.52 to -0.27). A negative association between fruit salad intake and WC was found (ß = -0.28; 95% CI -0.56 to -0.01). No statistically significant association between fruit salad intake and BMI was found. In the case of fruit juice, for each glass of juice consumed, the BMI increased by 0.27 kg/m2 (ß = 0.27; 95% CI 0.14 to 0.40), while the WC increased by 0.40 cm (ß = 0.40; 95% CI 0.20 to 0.60). Fruit intake per serving is negatively related to general body adiposity and central fat distribution, while fruit salad intake is negatively related to central distribution adiposity. However, the consumption of fruit in the form of juices is positively associated with a significant increase in BMI and WC.

Rendimiento diagnóstico de once indicadores para resistencia a la insulina en una muestra de pobladores peruanos

Introducción: La resistencia a la insulina (RI) es una de las principales causas del desarrollo de patologías crónicas. Es indispensable su detección temprana, por ello es importante estudiar métodos más asequibles y menos costosos como los biomarcadores. Objetivo: Determinar la precisión diagnóstica de once biomarcadores para RI en una muestra de pobladores peruanos. Metodología: Estudio de pruebas diagnósticas. Análisis de base de datos secundario del estudio PERU MIGRANT. Para medir RI se utilizó como referencia la evaluación del modelo homeostático (HOMA-IR) ≥ 2,8. Los biomarcadores se basaron en la ratio de lípidos, los indicadores de lípido visceral, los indicadores con triglicéridos y glucosa (TyG), y los indicadores con cintura abdominal. Para la precisión se utilizó el análisis de la curva de características operativas del receptor y el área bajo la curva (AUC) con sus respectivos intervalos de confianza al 95% (IC95%). Resultados: Se estudió a 938 participantes. La prevalencia de RI fue del 9,91%. En relación con el análisis ROC, el índice TyG - índice de masa corporal (TyG - IMC) tuvo el mayor AUC, tanto en hombres: AUC=0,85 (0,81 - 0,90), corte=241,55; sens=92,5 (79,6 - 98,4) y esp=78,3 (73,9 - 82,2); como en mujeres: AUC=0,81 (0,76 - 0,85), corte=258,77; sens=79,2 (70,3 - 86,5) y esp= 82,1 (78,0 - 85,8). Discusión: Según los datos analizados, el índice TyG-IMC es el mejor indicador para medir RI. Es un índice simple que se puede tomar de manera rutinaria en la práctica clínica diaria. Es conveniente añadir futuros estudios prospectivos que confirmen su capacidad predictiva.

Introduction: Insulin resistance (IR) is one of the main causes of chronic disease. Early detection is essential, which is why it is important to study more affordable and less expensive methods, such as biomarkers. Objective: To determine the diagnostic accuracy of 11 biomarkers of IR in a sample of Peruvian residents. Method: diagnostic tests. Secondary Database Analysis of the PERU-MIGRANT Study. To measure RI, a homeostatic model evaluation (HOMA-IR) ≥ 2.8 was used as a reference. Biomarkers were based on the lipid ratio, visceral lipid indicators, indicators of triglycerides and glucose (TyG), and indicators of abdominal waist. For precision, the receiver operating characteristic curve and area under the curve (AUC) with their respective 95% confidence intervals (95%CI) were used. Results: A total of 938 participants were studied. The prevalence of IR was 9.91%. In relation to the ROC analysis, the TyG index - body mass index (TyG - BMI) had the highest AUC, both in men: AUC=0.85 (0.81 - 0.90), cut-off=241.55; sens=92.5 (79.6 - 98.4) and sp=78.3 (73.9 - 82.2); as in women: AUC=0.81 (0.76 - 0.85), cut-off=258.77; sens=79.2 (70.3 - 86.5) and esp= 82.1 (78.0 - 85.8). Discussion: According to the data analyzed, the TyG-IMC index is the best indicator for measuring IR. It is a simple index that can be routinely used in clinical practice. Future prospective studies are needed to confirm its predictive capacity.

Conclusão: É essencial reforçar as estratégias de triagem no nível da atenção primária através da implementação de medidas preventivas.

Riesgo de preeclampsia y suplementación de vitamina C y E: revisión sistemática y metanálisis / Risk of preeclampsia and Vitamin C and E supplementation: a systematic review and meta-analysis

RESUMEN Introducción: Se ha sugerido que la preeclampsia puede ser prevenida por la ingesta de vitamina E y C, dado el mecanismo fisiopatológico de esta enfermedad. Objetivo: Determinar la eficacia conjunta de la vitamina C y E en la prevención de la preeclamsia. Métodos: Revisión sistemática de ensayos clínicos aleatorizados. Se realizó una búsqueda en las bases de datos pubmed/medline, SCOPUS, Web of Science, Cochrane Library, EMBASE, y Clinical Trials. El riesgo de sesgo de los ensayos clínicos aleatorios se evaluó mediante la herramienta Cochrane versión 2. Se realizó un metanálisis de efectos aleatorios y se calcularon los riesgos relativos, con los correspondientes intervalos de confianza al 95 %. Resultados: Se incluyeron 7 estudios (n= 1 475). No se encontró asociación estadísticamente significativa del tratamiento con suplementación de vitamina C y E con respecto a la preeclampsia (riesgo relativo: 1,03; IC95 %: 0,78-1,26). Conclusiones: La suplementación dual de vitamina C y E no previene la preeclamsia en gestantes con riesgo de padecer la enfermedad.

ABSTRACT Introduction: It has been suggested that preeclampsia can be prevented by vitamin E and C intake, given the pathophysiological mechanism of this disease. Objective: To determine the joint efficacy of vitamin C and E in the prevention of preeclampsia. Methods: Systematic review of randomized clinical trials. A search of pubmed/medline, SCOPUS, Web of Science, Cochrane Library, EMBASE, and Clinical Trials databases was performed. The risk of bias of the randomized clinical trials was assessed using the Cochrane tool version 2. A random-effects meta-analysis was performed and relative risks were calculated, with corresponding 95 % confidence intervals. Results: Seven studies were included (n= 1 475). No statistically significant association of treatment with vitamin C and E supplementation was found with respect to preeclampsia (relative risks: 1.03; 95 % CI 0.78-1.26). Conclusions: Dual vitamin C and E supplementation does not prevent preeclampsia in pregnant women at risk for the disease.

Factors associated with knowledge of p-value in a sample of medical students

Introduction: The role of p-value knowledge for clinical practice is elemental; however, insufficient evidence on this is found in health science students. Objective: To determine the factors associated with p-value knowledge in human medical students. Methods: Analytical cross-sectional study. Application of a virtual survey to human medicine students from different faculties in Peru. Results: 54.69% had sufficient knowledge of p-value. The multivariate analysis found a statistically significant association with having sufficient knowledge on this topic in those who were between 6th to 9th semester (APr: 1.118; 95% CI 1.051 - 1.412; p=0.009) and medical internship (APr: 1.234; 95% CI 1.073 - 1.418; p=0.003); taking an external course in biostatistics, epidemiology or research (APr: 1.420; 95% CI 1.227 - 1.643; p<0.001); having read 6 to 12 articles per year (APr: 1.353; 95% CI 1.196 - 1.530; p<0.001) and more than 12 articles per year (APr: 1.590; 95% CI 1.313 - 1.967; p<0.001); and publishing at least one scientific article (APr: 1.397; 95% CI 1.199 - 1.628; p<0.001) or more than one (APr:1.424; 95% CI 1.196 - 1.696; p<0.001). Conclusion: It was found that the academic semester, having taken an external course, having read more than 6 articles per year and having published at least one scientific article are independently associated with having greater understanding of this topic.

Conclusión: Los hallazgos mostraron que el semestre académico, haber llevado un curso externo, leído más de 6 artículos por años y publicado al menos un artículo científico se asocian independientemente con tener un mayor entendimiento de este tópico.

Factores asociados al fenotipo delgado metabólicamente obeso en pobladores peruanos

Introducción: Los pacientes con el fenotipo delgado metabólicamente obeso (DMO) pueden presentar el mismo riesgo que los obesos clásicos para desarrollar enfermedades crónicas a largo plazo. No obstante, la prevalencia y los factores que se encuentran asociados este varía de acuerdo con la población estudiada. Objetivo: determinar la prevalencia y los factores se encuentran asociados al fenotipo DMO en el Perú. Métodos: Estudio analítico de corte transversal. Análisis secundario de la base de datos del estudio PERU MIGRANT. Los factores asociados que se consideraron fueron: edad (30-44 años, de 45-59 años, y 60 a más años), sexo, estado socioeconómico, nivel de educación, migración, tabaquismo, consumo de alcohol y nivel actividad física. Resultados: La prevalencia del fenotipo DMO fue de 32,23% (IC95% 27,61-37,10). En el análisis multivariable, el sexo masculino mostró 39% menor probabilidad de presentar el fenotipo DMO (PRa: 0,610; IC95% 0,428-0,869; p=0,006), en comparación con el sexo femenino. Mientras que, pertenecer a los grupos de edad entre 45-59 años y de 60 años a más presentó 110,5% (PRa: 2,105; IC95% 1,484-2,988; p<0,001) y 97,6% (PRa: 1,976; IC95% 1,270-3,075; p=0,003), respectivamente, mayor probabilidad de presentar DMO, en comparación con el grupo de 29-44 años. Conclusiones: El pertenecer al sexo femenino y a los grupos de edad de 45 a 59 y 60 años a más, aumentaron la probabilidad de presentar el fenotipo DMO. Se recomienda la realización de futuros estudios con prospectivos y con un tamaño de muestra mayor para confirmar dichos hallazgos, así como la inclusión de nuevas variables.

Introduction: Patients with the lean metabolically obese (BMD) phenotype may present the same risk as the classic obese for developing long-term chronic diseases. However, the prevalence and the factors that are associated with it vary according to the population studied. Objective: to determine the prevalence and the factors associated with the BMD phenotype in Peru. Methods: Cross-sectional analytical study. Secondary analysis of the PERU MIGRANT study database. The associated factors that were considered were: age (30-44 years, 45-59 years, and 60 years and over), sex, socioeconomic status, level of education, migration, smoking, alcohol consumption and level of physical activity. Results: The prevalence of the BMD phenotype was 32.23% (95% CI 27.61-37.10). In the multivariate analysis, the male sex showed a 39% lower probability of presenting the BMD phenotype (PRa: 0.610; 95% CI 0.428-0.869; p=0.006), compared to the female sex. While belonging to the age groups between 45-59 years and 60 years and over presented 110.5% (PRa: 2.105; 95% CI 1.484-2.988; p<0.001) and 97.6% (PRa: 1.976; CI95% 1.270-3.075; p=0.003), respectively, greater probability of presenting BMD, compared to the group of 29-44 years. Conclusions: Belonging to the female sex and to the age groups of 45 to 59 and 60 years or more, increased the probability of presenting the BMD phenotype. Future prospective studies with a larger sample size are recommended to confirm these findings, as well as the inclusion of new variables.

Conocimientos, actitudes y prácticas sobre el consumo de sal en la población peruana: Estudio transversal / Knowledge, attitudes and practices about salt consumption in the Peruvian population: A crosssectional study

Introducción: La reducción del consumo de sal se ha identificado como una de las intervenciones prioritarias para prevenir las enfermedades no transmisibles a nivel mundial. Por ello, se recomienda que uno de los tres pilares para reducir su ingesta es reconocer el nivel de conocimientos, actitudes y prácticas relacionadas con el consumo de sal (CAP-sal). Objetivo: Determinar el nivel de CAP-sal y los factores asociados a estos en la población peruana. Materiales y métodos: Estudio transversal analítico realizado mediante encuesta virtual en población adulta peruana. Resultados: Se trabajó con una muestra de 918 sujetos. La proporción de participantes con conocimiento, actitudes y prácticas suficientes, fue del 54,58 %; 50,22 % y 40,31 %, respectivamente. Las variables que aumentan la probabilidad de tener un nivel suficiente de CAP-sal fueron el sexo femenino, la presencia de obesidad e HTA. Mientras que los antecedentes familiares y área de residencia lo fueron únicamente para conocimientos, el grado de instrucción para conocimientos y prácticas, y la actividad física tanto para actitudes como prácticas. Conclusiones: Tanto el nivel de conocimiento y actitudes fueron suficientes en la mitad de la muestra, pero las prácticas se encuentran por debajo de esta. Existen brechas que varían según las características sociodemográficas, como la edad, sexo, antecedentes de HTA, obesidad y realización de actividad física. Resultados que podrían apoyar la inclusión de la promoción de una nutrición saludable en la población peruana(AU)

Introduction: Reducing salt intake has been identified as one of the priority interventions to prevent non-communicable diseases worldwide. For this reason, it is recommended that one of the three pillars to reduce its intake is to recognize the level of Knowledge, Attitudes and Practices related to salt consumption (CAP-salt, in Spanish). Objective: To determine the level of CAP-salt and the factors associated with these in the Peruvian population. Materials and Methods: Cross-sectional analytical study carried out through a virtual survey of the Peruvian population. Results: We studied 918 subjects. The proportion of patients with sufficient knowledge, attitudes and practices was 54.58 %; 50.22 % and 40.31 %, respectively. The factors that increase the probability of having sufficient CAPsalt were female sex, the presence of obesity and hypertension. While family history and area of residence were only for knowledge, the degree of education for knowledge and practices, and physical activity for both attitudes and practices. Conclusions: The level of knowledge and sufficient attitudes are present in half of the population, but the practices are below this. In turn, several gaps vary according to sociodemographic characteristics, such as age, sex, history of hypertension, obesity, and physical activity, which could be the target of the new population awareness goals(AU)

Validez de contenido por juicio de expertos de un instrumento para medir conocimientos, actitudes y prácticas sobre el consumo de sal en la población peruana / Content validity by expert judgment of an instrument to measure knowledge, attitudes and practices about salt consumption in the peruvian population

Introducción: Ante el alto consumo de sal en la población, surge la necesidad de contar con una herramienta validada que mida los conocimientos, actitudes y prácticas del consumo de sal (CAP-sal). Objetivo: Validar el cuestionario de CAP-sal. Métodos: Estudio psicométrico de validez de contenido a través de juicio de expertos. Se contó un total de 5 médicos de diferentes especialidades. Para calcular el grado de acuerdo entre los jueces expertos se utilizó la V de Aiken Como criterio de decisión para mantener un ítem, se consideró un valor ≥ 0,7. Resultados: En relación a la claridad, se presentaron valores V superiores a 0,80, además, de un coeficiente de variación menor a 25%, por tanto, ninguno de los ítems fue eliminado. Con respecto a coherencia, presentaron un coeficiente de variación por encima del 20% y valores V superiores a 0,71, confirmando la decisión de no excluir alguno de ellos. Sobre la relevancia de los ítems, se evidenció también valores V superiores a 0,90 y tampoco presentó alguno un valor por debajo del crítico. Conclusiones:El cuestionario ha presentado suficientes evidencias de validez de contenido en claridad, coherencia y relevancia de los ítems a través de los análisis antes mencionados. Por eso mismo, debería ser utilizado para cuantificar el CAP-sal de diferentes grupos poblacionales del país.

Introduction: Given the high consumption of salt in the population, the need arises to have a validated tool that measures the knowledge, attitudes and practices of salt consumption (CAP-salt). Objective: To validate the questionnaire on CAP-salt. Methods: Psychometric study of content validity through expert judgment. A total of 5 physicians from different specialties were counted. To calculate the degree of agreement between the expert judges, Aiken's V was used. As a decision criterion to keep an item, a value ≥ 0.7 was considered. Results: In relation to clarity, V values greater than 0.80 were presented, in addition to a variation coefficient of less than 25%, therefore, none of the items was eliminated. Regarding coherence, they presented a coefficient of variation above 20% and V values greater than 0.71, confirming the decision not to exclude any of them. Regarding the relevance of the items, V values higher than 0.90 were also evidenced and neither did any of them present a value below the critical one. Conclusions: The questionnaire has presented sufficient evidence of content validity in terms of clarity, coherence and relevance of the items through the aforementioned analyses. For this reason, it should be used to quantify the KAP of different population groups in the country.

Hypertriglyceridemic waist and arterial hypertension in adults: a systematic review and meta-analysis / Cintura hipertrigliceridémica e hipertensión arterial en adultos: una revisión sistemática y metaanálisis

Objective: To develop a systematic review and meta-analysis to determine the association between hypertriglyceridemic waist (CHTG) and arterial hypertension (HBP) in adults. Materials: The present study is a systematic review (SR) with meta-analysis of analytical cross-sectional observational studies. Search strategies will be used in different databases, which will be Pubmed, SCOPUS, Web of Science, Embase. The qualitative analysis was presented in a table with the characteristics of each study. For quantitative analysis, random-effects meta-analysis was performed due to the heterogeneity of the studies. These variables were compared using Odds Ratios (OR) as a measure of association with their corresponding 95% confidence interval. Results: Five studies were included for statistical analysis. Overall, a statistically significant association was found between both variables (OR: 1.36; 95% CI 1.07 to 1.71). In turn, there was a high heterogeneity (I squared 92%). Conclusions: This SR found that CHTG is associated with the presence of hypertension. However, given the few studies found, it is recommended to carry out more primary studies with a prospective design before carrying out a next SR on the subject, and with standardized cut-off points to make a more homogeneous comparability.

Objetivo: Desarrollar una revisión sistemática y metaanálisis para determinar la asociación entre la cintura hipertrigliceridémica (CHTG) e hipertensión arterial (HTA) en adultos. Materiales: El presente estudio es una revisión sistemática (RS) con metanálisis de estudios observacionales de corte transversal analítico. Se utilizarán estrategias de búsqueda en diferentes bases de datos las cuales serán Pubmed, SCOPUS, Web of Science, Embase. El análisis cualitativo fue presentado en una tabla con las características de cada estudio. Para el análisis cuantitativo, se realizó el metaanálisis de efectos aleatorios debido a la heterogeneidad de los estudios. Dichas variables fueron comparadas usando como medida de asociación Odds Ratios (OR) con su correspondiente intervalo de confianza al 95%. Resultados: Se incluyeron 5 estudios para el análisis estadístico. De manera global, se encontró asociación estadísticamente significativa entre ambas variables (OR: 1,36; IC 95% 1,07 a 1,71). A su vez, se presentó una alta heterogeneidad (I cuadrado del 92%). Conclusiones: La presente RS encontró que la CHTG está asociado con la presencia de HTA. No obstante, dado los pocos estudios encontrados, se recomienda la realización de más estudios primarios con un diseño prospectivo antes de la realización de una siguiente RS del tema, y con puntos de corte estandarizados para hacer una comparabilidad más homogénea.

Cintura hipertrigliceridémica y su asociación con la hipertensión arterial una muestra de pobladores adultos peruanos / Hypertriglyceridemic waist circumference and its association with arterial hypertension in a sample of Peruvian adult population

Objetivo: Evaluar la prevalencia de cintura hipertrigliceridémica (CHTG) y su asociación con hipertensión arterial (HTA) en pobladores adultos peruanos. Metodología: Estudio transversal analítico de base de datos secundario de la "Encuesta Nacional de Indicadores Nutricionales, Bioquímicos, Socioeconómicos y Culturales relacionados con las Enfermedades Crónicas-Degenerativas". La CHTG se midió de acuerdo con la presencia de hipertrigliceridémica (≥ 150 mg/dl) y cintura abdominal aumentada, según los criterios JIS (hombres ≥ 94 cm y mujeres ≥ 80 cm) y ATPIII (hombres ≥ 102 cm y mujeres ≥ 88 cm). Resultados: La prevalencia de HTA fue 12,48 %, de CHTG-JIS fue 21,49% y CHTG-ATPII fue 13,96%. En la regresión múltiple, la CHTG-JIS mostro que tenían 1,35 mayor frecuencia de tener HTA versus quienes no presentaban CHTG (RP=1,35; IC95%: 1,13 ­ 1,61; p = 0.001) y la CHTG-ATPIII observó que tenían 1,38 mayor frecuencia de tener HTA versus quienes no presentaban CHTG (RP=1,38; IC95%: 1,14 ­ 1,67; p=0.001), ambos ajustados por variables convenientes. Conclusión: La CHTG se asoció positivamente con HTA.

Objective: To evaluate the prevalence of hypertriglyceridemic waist (HTGW) and its association with arterial hypertension (AHT) in Peruvian adults. Methodology: Cross-sectional analytical study of the secondary database from the "National Survey of Nutritional, Biochemical, Socioeconomic and Cultural Indicators related to Chronic-Degenerative Diseases". HTGW was measured according to the presence of hypertriglyceridemia (≥ 150 mg/dl) and increased abdominal waist, according to JIS (men ≥ 94 cm and women ≥ 80 cm) and ATPIII (men ≥ 102 cm and women ≥ 88 cm) criteria. Results: the prevalence of AHT was 12.48%, HTGW -JIS was 21.49%, and HTGW-ATPII was 13.96%. In multiple regression, HTGW-JIS showed that they had 1.35 higher frequency of having AHT versus those without HTGW (PR=1.35; CI95%: 1.13 - 1.61; p = 0.001) and HTGW-ATPIII showed that they had 1.38 higher frequency of having AHT versus those without HTGW (PR=1.38; CI95%: 1.14 - 1.67; p = 0.001), both adjusted for convenience variables. Conclusion: HTGW was positively associated with AHT.
