Changes in lifestyle behaviors during COVID-19 isolation in Argentina: A cross-sectional study.

OBJECTIVE: Our aim was to identify changes in population habits induced by COVID-19 confinement in Argentina. METHODS: An internet-based cross-sectional survey was conducted among adults in Argentina on December 2020, requesting possible changes occurring during the COVID-19 outbreak. It included 26 questions regarding general information (age, gender, location), eating habits, desire/anxiety for food or to eat between meals, weight gain, physical activity, and hours of sleep. We ran a descriptive statistical analysis of changes in habits and lifestyle during the confinement, followed by a logistic regression analysis to explore the relation between these changes and weight gain. Results: Out of 1536 survey participants, 57.1% were female, aged 38.8 ± 13.1 years. Data showed that during the outbreak, people experienced significant changes in food intake, physical activity, nutritional supplement consumption, anxiety, and sleeping disorders. These changes in behavior resulted in an elevated percentage of people (39.7%) that gained weight (average 4.8 ± 2.8 kg). Weight gain was associated with more food consumption (OR: 9.398), increased snacking between meals (OR: 1.536), anxiety about food (OR: 3.180), less practice of physical activity (OR: 0.586) and less consumption of nutritional supplements (OR: 0.762). Conclusions: COVID-19 outbreak was associated with unhealthy lifestyle changes and body weight increase. These adverse side effects could be prevented by active promotion of nutritional advice and physical activity, implementing virtual activities associated with regular mass promotion campaigns.

Visión epidemiológica, psicosocial y terapéutica de la diabetes mellitus en Argentina desde las perspectivas del equipo de salud y de las personas con diabetes / Epidemiological, psychosocial and therapeutic vision of diabetes mellitus in Argentina from the perspectives of health team and people with diabetes

Introducción: la diabetes mellitus (DM) genera una pesada carga socioeconómica, y para su abordaje es necesario indagar sobre sus posibles condicionantes para lograr su control, prevención y tratamiento efectivo. Objetivos: entender la problemática de la DM en Argentina y las estrategias para mejorarla según la perspectiva de los profesionales de la salud y de las personas con DM. Materiales y métodos: se implementó un estudio descriptivo con metodología cualitativa basado en la técnica del Metaplan. Se diseñó un cuestionario con dos preguntas (¿Cuáles son a su criterio los problemas que enfrenta la DM en nuestro país?, ¿Qué estrategias emplearía para solucionarlos?), que se distribuyó entre los profesionales de la salud y las personas con DM vía Internet a través de sus respectivas Sociedades, durante junio-julio de 2021. Los participantes (adultos, residentes en Argentina) debían responder hasta cuatro alternativas en cada pregunta. Se revisaron todas las respuestas recibidas, se las agrupó por temas y se las analizó/cuantificó mediante técnicas descriptivas expresando los resultados como porcentajes. Resultados: la muestra final incluyó 404 profesionales del equipo de salud y 272 personas con DM, mayoritariamente con DM1. El análisis demostró que existe: a) una organización deficiente de la cobertura; b) un predominio de hábitos no saludables; c) escasa provisión de educación diabetológica estructurada que dificulta el diagnóstico y el tratamiento adecuado, y falta de capacitación al paciente para participar activa y eficientemente en el control y tratamiento de su enfermedad; d) deficiente calidad de atención. Conclusiones: los resultados, similares a los obtenidos en otros países, sugieren que las estrategias de solución implicarían la restructuración de la formación médica para lograr un balance armónico entre el nivel primario de atención y las especialidades, disminuyendo además la carga psicológica del paciente, la cual se vería facilitada mediante la cooperación armónica de las instituciones educativas y las sociedades científicas, al igual que con una intervención consensuada de diferentes sectores de la sociedad.

Introduction: diabetes mellitus (DM) generates a heavy socioeconomic burden, and to address it, it is necessary to investigate its possible conditioning factors to achieve effective control, prevention, and treatment. Objectives: to understand the problem of diabetes in Argentina, from the perspective of health professionals and people with DM and the strategies to improve it. Materials and methods: it was implemented a descriptive study with qualitative methodology based on the metaplan technique. A questionnaire was designed with two questions (What are, in your opinion, the problems faced by diabetes in our country?, What strategies would you use to solve them?), which was distributed to health professionals and people with DM via the Internet of their respective Societies during JuneJuly 2021. The participants (adults, residents of Argentina) had to answer up to 4 alternatives in each question. All the responses received were reviewed, grouped by topic and analyzed/ quantified using descriptive techniques, expressing the results as percentages. Results: the final sample included 404 professionals from the health team and 272 people with DM: mostly with type 1 DM. The analysis shows that there is: a) a poor organization of coverage; b) a predominance of unhealthy habits; c) scarce provision of structured diabetes education, which makes it difficult to diagnose and adequately treat, and train patients to participate actively and efficiently in the control and treatment of their disease; d) there is a deficient quality of care. Conclusions: our results, similar to those obtained in other countries, suggest that the solution strategies would go through the restructuring of medical training, achieving a harmonious balance between the primary level of care and the specialties, adding a decrease in the psychological burden of the patient. It would be facilitated by the harmonious cooperation of educational institutions and scientific societies. Likewise, through a consensual intervention of different sectors of society.

Aislamiento por Covid-19 en el Amba y en el resto del pais: estudio transversal de cambios en el hábitos y estilo de vida / Isolation by Covid-19 in the Amba and the rest of the country: cross-sectional study of changes in habits and lifestyle

Introducción: el confinamiento impuesto para disminuir la propagación de la COVID-19 induce cambios de hábitos y estilos de vida no saludables. Objetivos: verificar cambios asociados al confinamiento en los hábitos alimentarios y estilo de vida en la población argentina, y sus diferencias entre el área metropolitana de Buenos Aires (AMBA) y el resto del país. Materiales y métodos: estudio transversal, descriptivo y analítico, mediante una encuesta "en línea" (diciembre de 2020) realizada a adultos residentes en Argentina. Se relevó edad, género y lugar de residencia, así como los cambios registrados respecto del peso, hábitos alimentarios, actividad física, deseo por comer y calidad del sueño. Se realizó un análisis descriptivo de las encuestas válidas recibidas (N=1.536), y se verificaron diferencias entre las regiones mediante pruebas paramétricas y no paramétricas, considerando significativo p<0,05.Resultados: el 75,1% de los participantes fue mujer (38,8±13,1 años), el 60,5% del AMBA y 39,5% del resto del país. El aislamiento se asoció a cambios que impactaron en lo psicológico, estrés, hábitos saludables y sueño, con algunas diferencias regionales significativas. Sin embargo, la resultante final común entre AMBA y el resto del país fue el mayor aumento de la ingesta calórica y la disminución de actividad física que condujo a que el 39,7% de los participantes aumentara su peso (media 4,8±2,8 kg). Conclusiones: el aislamiento se asoció con efectos secundarios indeseables que podrían disminuirse mediante la promoción virtual de hábitos saludables que, simultáneamente, disminuirían el aumento de la obesidad y la diabetes

Introduction: the confinement imposed to reduce the spread of COVID-19 induces changes in habits and unhealthy lifestyles. Objectives: to verify changes associated with confinement in eating habits and lifestyle in the Argentine population and their differences between the metropolitan area of Buenos Aires (AMBA) and the rest of the country. Materials and methods: cross-sectional, descriptive, and analytical study, through an "online" survey (December 2020) carried out on adults residing in Argentina. Age, gender and place of residence were surveyed, as well as the changes registered regarding weight, eating habits, physical activity, desire to eat and quality of sleep. A descriptive analysis of the valid surveys received (N=1,536) was carried out, verifying differences between the regions using parametric and nonparametric tests, considering significant p<0.05. Results: 75.1% of the participants were women (38.8±13.1 years), 60.5% from the AMBA and 39.5% from the rest of the country. Isolation was associated with changes that impacted on the psychological, stress, healthy habits, and sleep, with some significant regional differences. However, the common end result between AMBA and the rest of the country was the greater increase in caloric intake and the decrease in physical activity that led to 39.7% of the participants increasing their weight (mean 4.8±2,8 kg). Conclusions: isolation was associated with undesirable side effects, which could be diminished through the virtual promotion of healthy habits that would simultaneously decrease the growth of obesity and diabetes

The triad macrosomia, obesity, and hypertriglyceridemia in gestational diabetes.

AIMS: Offspring of women with gestational diabetes (GD) have more macrosomia than newborns of normal mothers. We studied macrosomia frequency, possible pathogenesis, and main predictors of its appearance at different gestational ages. MATERIALS AND METHODS: A total of 1870 pregnant women with GD were recruited in primary care centres and maternity hospitals in the Argentine provinces of Corrientes, Chaco, Buenos Aires, and in Buenos Aires City; 1088 completed gestation and delivered an infant. We collected clinical and metabolic data, personal and obstetric history, and gestational and delivery characteristics. Presence of macrosomia was analysed in the whole population, the entire pregnancy, and in each trimester of gestation. Data were statistically analysed and values were expressed as mean ± SD and percentages. The study protocol was approved by the Ethics Committee and all participants signed informed consent. RESULTS: Macrosomia was found in 12.9% of newborns and obesity in all mothers with no significant differences between mothers with/without macrosomic offspring. In early pregnancy, the main significant indicators of macrosomia were: history of dyslipidaemia (5.6% vs 1.2%, respectively) and macrosomia in previous pregnancies (27% vs 13%, respectively). However, the third trimester showed a significant combination of higher BMI, FBG, and triglycerides. CONCLUSIONS: Offspring of women with GD presented macrosomia in 12.9% of cases, maternal history of dyslipidaemia and macrosomia in previous pregnancies being early predictors. The combination of maternal obesity, FBG, and hypertriglyceridemia became significant during the last trimester of pregnancy.

Treat-to-target HbA1c and lipid profile to prolong ß-cell mass/function and optimize treatment goal attainment.

BACKGROUND: To evaluate the relation between different serum lipid fractions and other known barriers to attain the HbA1c  ≤ 7.0% (53 mmol/mol) target. METHODS: Data on 2719 patients with type 2 diabetes were collected from the five waves of the International Diabetes Mellitus Practice Study implemented in Argentina (2006 to 2012) including demographic/socioeconomic profile, clinical, metabolic (HbA1c and serum lipids) data, and treatment type and also, percentage of treatment goal attainment. Descriptive statistical analyses included ANOVA, χ2 test, and Fisher exact test and univariate and multivariate logistic regression analyses, which identified predictive factors for HbA1c  ≤ 7% (53 mmol/mol). RESULTS: The average age was 63 years, primary/secondary education, health insurance, 10-year type 2 diabetes duration, most associated with cardiovascular risk factors and some microvascular/macrovascular complications; 94.5% received antihyperglycaemic drugs. Percentage of people on target: HbA1c 51.2%, blood pressure 23.5%, total cholesterol 62.6%, low-density lipoprotein (LDL) cholesterol 38.9%, and triglycerides 61.1%. HbA1c on target depended markedly on treatment type: more of those treated with lifestyle changes and significantly fewer of those receiving insulin. Only 4.1% had all parameters simultaneously on target. Multivariate logistic regression analyses showed that achieving HbA1c  ≤ 7.0% (53 mmol/mol) was associated with higher educational level, shorter diabetes duration, and having reached goals for LDL cholesterol and triglycerides, whereas opposite results were obtained with insulin treatment and longer diabetes duration. CONCLUSIONS: High LDL cholesterol and triglyceride levels simultaneously potentiate development/progression of chronic complications, exerting this effect in the long term by decreasing ß-cell mass/function, thereby making it more difficult to reach HbA1c values able to prevent complications.

Diabetes management and treatment approaches outside of North America and West Europe in 2006 and 2015.

AIMS: The impact of introducing new classes of glucose-lowering medication (GLM) on diabetes management remains unclear, especially outside North America and Western Europe. Therefore, we aimed to analyse trends in glycaemic control and the usage of new and old GLMs in people with type 2 diabetes from 2006 to 2015. METHODS: Summary data from clinical services from nine countries outside North America and Western Europe were collected and pooled for statistical analysis. Each site summarized individual-level data from out-patient medical records for 2006 and 2015. Data included: demographics; HbA1c and fasting plasma glucose levels; and the proportions of patients taking GLM as monotherapy, combination therapy and/or insulin. RESULTS: Between 2006 and 2015, glycaemic control remained stable, although body mass index and duration of diabetes increased in most sites. The proportion of people on GLM increased, and the therapeutic regimens became more complex. There were increases in the use of insulin and triple therapy in most sites, while monotherapy, particularly in relation to sulphonylureas, decreased. Despite the introduction of new GLMs, such as DPP-4 inhibitors, insulin use increased over time. CONCLUSIONS: There was no clear evidence that the use of new classes of GLMs was associated with improvements in glycaemic control or reduced the reliance on insulin. These findings were consistent across a range of economic and geographic settings.

Drug treatment of type 2 diabetes: Its cost is significantly associated with HbA1c levels.

AIMS: To examine the relationship between costs of hyperglycaemia drug treatment and glycemic control amongst people with type 2 diabetes (T2D). METHODS: This observational study utilised data from the QUALIDIAB database on 3,452 T2D patients seen in Diabetes Centers in Argentina. Patients were classified according to their HbA1c value into two groups: on target (OT; HbA1c ≤ 7%), and not on target (NOT; HbA1c > 7%); within each category we considered clinical and metabolic indicators, as well as type of hyperglycaemia treatment. Monthly expenditure on drugs was estimated by micro-costing. Multivariable regression analysis was used to evaluate the association between cost of hyperglycaemia treatment and HbA1c values. RESULTS: In total, 48.9% of the participants have HbA1c OT values. Overall monthly per capita costs of this treatment increased significantly (134%) in the NOT group. Multivariable regression analysis showed that expenditure for hyperglycaemia drugs treatment was significant associated with glycemic control (OR: 0.705), diabetes duration (OR: 1.017), systolic blood pressure (OR: 1.006) and treatment of T2D (OR: 2.622). CONCLUSIONS: HbA1c NOT significantly increases drugs monthly cost of hyperglycaemia treatment in people with T2D in a country with an emerging market economy.

Beneficio económico de los ensayos clínicos controlados patrocinados: El gasto evitable en medicamentos para el tratamiento de la artritis reumatoidea.

OBJECTIVES: To estimate the following: (1) the avoidable cost of biologic (bDMARDs) and conventional synthetic Rheumatoid Arthritis (RA) modifying antirheumatic drugs (csDMARDs) during controlled clinical trials (CCTs), their extension period, and for bDMARDs in post study drug programs; and (2) to evaluate the impact on health insurances. METHODS: We analyzed 13 CCTs (233 patients) that evaluated bDMARDs. Avoidable cost was what the health insurance should have paid if the patient had not received the medication from the CCT sponsor and was estimated with a micro-costing approach (bottom-up method). Results were expressed as mean ± standard deviation (SD) or percentages. Approved by the Ethics Committee. RESULTS: Mean age was 50.62 SD 11.8 years, 84% were women, 72% (n = 166) had health insurance. The mean annual cost of bDMARDs was US$ 30 567.40 while the cost for csDMARDs was US$ 104.90 during the CCTs. The mean annual cost in extension periods and post study drug programs for bDMARDs was US$ 36 016.20 and for csDMARs during the extension period was US$ 81.70. The avoidable cost for public health insurances exceeded one million dollars per year. CONCLUSION: This work describes for the first time in Argentina the significant economic benefit that may represent for RA patients' health insurances the participation in CCTs with bDMARDs. It shows that during the execution of the CCT, its extension periods, or post study access programs, while medication provision is guaranteed, the economic burden imposed by the treatment of the RA is relieved.

Clinical and Economic Value of p16INK4a for the Differential Diagnosis of Morphologic Cervical Intraepithelial Neoplasia 2.

The detection of high-grade intraepithelial lesions requires highly sensitive and specific methods that allow more accurate diagnoses. This contributes to a proper management of preneoplastic lesions, thus avoiding overtreatment. The purpose of this study was to analyze the value of immunostaining for p16 in the morphologic assessment of cervical intraepithelial neoplasia 2 lesions, to help differentiate between low-grade (p16-negative) and high-grade (p16-positive) squamous intraepithelial lesions. The direct medical cost of the treatment of cervical intraepithelial neoplasia 2 morphologic lesions was estimated. A retrospective observational cross-sectional study was carried out. This study analyzed 46 patients treated with excisional procedures because of cervical intraepithelial neoplasia 2 lesions, using loop electrosurgical excision procedures. Immunostaining for the biomarker was performed. For the estimation of overtreatment, percentages (%) and their 95% confidence interval were calculated. Of the 41 patients analyzed, 32 (78%) showed overexpression of p16 and 9 (22%) were negative (95% confidence interval, 11%-38%). Mean follow-up was 2.9 years, using cervical cytology testing (Pap) and colposcopy. High-risk human papillomavirus DNA tests were performed in 83% of patients. These retrospective results reveal the need for larger biopsy samples, which would allow a more accurate prediction of lesion risk. Considering the cost of p16 staining, and assuming the proper management of the low-grade lesion, an average of US$919 could be saved for each patient with a p16-negative result, which represents a global direct cost reduction of 10%.

Educación terapéutica de mujeres con diabetes gestacional (EDUGEST): datos correspondientes al período de reclutamiento / Education of pregnant women with gestational diabetes (EDUGEST): data collected in the recruitment period

Introducción: la prevalencia de diabetes gestacional (DG) en Argentina es de 4,7%, lo que implica mayor riesgo de desarrollar complicaciones tanto maternas como del recién nacido, prevenibles mediante un diagnóstico precoz y un tratamiento oportuno. Objetivos: promover la consulta precoz, el diagnóstico oportuno y el tratamiento adecuado mediante un programa de educación estructurado y multidisciplinario a nivel de Centros de Atención Primaria de la Salud (CAPs) y maternidades. Materiales y métodos: se reclutaron embarazadas con DG en CAPs y maternidades de Buenos Aires, Corrientes, Chaco y Ciudad Autónoma de Buenos Aires (CABA), con la participación de obstetras, diabetólogos, enfermeras, asistentes sociales, educadores, nutricionistas y médicos comunitarios. Para el diagnóstico de DG se aplicaron los criterios de la Asociación Latinoamérica de Diabetes (ALAD) y se relevaron simultáneamente hábitos nutricionales y parámetros clínicos, metabólicos y terapéuticos. También se desarrollaron cursos de educación y seguimiento durante el embarazo, parto, postparto y lactancia. Resultados: las embarazadas con DG consultaron tardíamente (la mayoría en el tercer trimestre de embarazo) y presentaron factores de riesgo para DG no prevenibles (el más frecuente fue el antecedente familiar de diabetes) y prevenibles (obesidad, hipertrigliceridemia y macrosomía) en embarazos previos. Conclusiones: el EduGest pretende interrumpir el círculo vicioso generado por la DG sobre la futura diabetes mellitus tipo 2 en la madre y el niño al promover la adopción de hábitos saludables

Introduction: in Argentina the prevalence of gestational diabetes (GD) is 4.7%, accounting for a higher risk of developing complications in both the mother and the baby which could be prevented by early diagnosis and timely treatment. Objectives: to promote early consultation, timely diagnosis and adequate treatment through a structured and multidisciplinary education Program in Primary Healthcare (PHU) and maternity (PMU) units. Materials and methods: pregnant women with DG were recruited in PHU and PMU from Buenos Aires, Corrientes, Chaco and CABA, Argentina. The program included the participation of obstetricians, diabetologists, nurses, social workers, educators, nutritionists and community doctors. The ALAD diagnostic criteria for DG were applied. Simultaneously, nutritional habits, clinical, metabolic and therapeutic parameters were recorded. Education and follow-up courses were developed during pregnancy, delivery, after delivery and breastfeeding. Results: late consultation was frequent in pregnant women with GD (mainly during the third trimester), who presented both non-preventable (the most frequent being family history of diabetes) and preventable (obesity, hypertriglyceridemia and macrosomia) risk factors for GD in previous pregnancies. Conclusions: EduGest is aimed at breaking the vicious circle of DG on the future development of type 2 diabetes in the mother and the baby by promoting the adoption of healthy habits

Ingesta alimentaria en la población adulta de dos ciudades de la Provincia de Buenos Aires: su adecuación a las necesidades nutricionales / FOOD INTAKE OF AN ADULT POPULATION IN TWO CITIES IN THE PROVINCE OF BUENOS AIRES: ITS ADEQUACY TO NUTRITIONAL RECOMMENDATIONS

Introducción: frecuentemente la ingesta alimentaria de las personas no coincide con las recomendaciones de salud. Objetivos: comparar la ingesta alimentaria de la población estudiada con las recomendaciones de las guías nacionales como base para definir los contenidos del plan de educación nutricional de un programa de prevención primaria de diabetes. Materiales y métodos: evaluamos la ingesta alimentaria de personas de 45 a 75 años, atendidas en el sector público de salud de La Plata y Berisso, entre marzo de 2015 y marzo de 2016. Utilizamos una encuesta de ingesta de alimentos estructurada y autoadministrada basada en un listado de alimentos de consumo habitual de nuestra población (NutriQuid). Los participantes completaron la encuesta durante dos días hábiles y un día de fin de semana. Verificamos el porcentaje de adecuación de la ingesta energética y nutrientes a las recomendaciones nutricionales del Ministerio de Salud de la Nación. En un subgrupo analizamos la relación entre el índice de masa corporal e ingesta energética y el consumo de sodio en hipertensos/normotensos. La evaluación estadística incluyó ANOVA y el test de t. Resultados: evaluamos las encuestas realizadas a 142 personas: 50% o más de la población encuestada siguió un plan de alimentación que no cumple con las recomendaciones del Ministerio de Salud de la Nación respecto de energía, proteínas, lípidos, sodio, ácidos grasos saturados, colesterol y azúcares refinados. Más del 80% de los participantes consumió cantidades insuficientes de fibra, potasio, frutas y verduras. Sólo un 27% de los hipertensos y un 14% de los normotensos consumieron las cantidades de sodio recomendadas. El 35% de los hipertensos y el 48% de los normotensos declararon consumir más del doble del valor recomendado. Conclusiones: consideramos que nuestros resultados apoyan la iniciativa de implementar un programa de educación alimentaria basado en las recomendaciones nutricionales.

Diabetes primary prevention program: New insights from data analysis of recruitment period.

BACKGROUND: Primary Prevention of Diabetes Program in Buenos Aires Province evaluates the effectiveness of adopting healthy lifestyle to prevent type 2 diabetes (T2D) in people at high risk of developing it. We aimed to present preliminary data analysis of FINDRISC and laboratory measurements taken during recruitment of people for the Primary Prevention of Diabetes Program in Buenos Aires Province in the cities of La Plata, Berisso, and Ensenada, Argentina. METHODS: People were recruited through population approach (house-to-house survey by FINDRISC in randomized areas) and opportunistic approach (FINDRISC completed by participants during consultations for nonrelated prediabetes/diabetes symptoms in public and private primary care centres of cities involved). In people with FINDRISC score ≥ 13 points, we evaluated blood concentrations of HbA1c , creatinine, lipids, and an oral glucose tolerance test (OGTT). RESULTS: Approximately 3415 individuals completed the FINDRISC populational survey and 344 the opportunistic survey; 43% of the 2 groups scored over 13 points; 2.8 and 75.4% of them, respectively, took the prescribed OGTT. Approximately 53.7% of the OGTT showed normal values and 5.2% unknown T2D. The remaining cases showed 69.5% impaired fasting glucose, 13.6% impaired glucose tolerance, and 16.9% both impairments. HbA1c values showed significant differences compared with normal glucose tolerance (4.96 ± 0.43%), prediabetes (5.28 ± 0.51%), and T2D (5.60 ± 0.51%). Participants with prediabetes and T2D showed a predominant increase in low-density lipoprotein-cholesterol values. In prediabetes, >50% showed insulin resistance. CONCLUSIONS: People with prediabetes/T2D had dyslipidemia associated with insulin resistance, which promotes the development of T2D and cardiovascular disease. Thus, it merits its appropriate treatment.

Relation between cost of drug treatment and body mass index in people with type 2 diabetes in Latin America.

AIMS: Despite the frequent association of obesity with type 2 diabetes (T2D), the effect of the former on the cost of drug treatment of the latest has not been specifically addressed. We studied the association of overweight/obesity on the cost of drug treatment of hyperglycemia, hypertension and dyslipidemia in a population with T2D. METHODS: This observational study utilized data from the QUALIDIAB database on 3,099 T2D patients seen in Diabetes Centers in Argentina, Chile, Colombia, Peru, and Venezuela. Data were grouped according to body mass index (BMI) as Normal (18.5≤BMI<25), Overweight (25≤BMI<30), and Obese (BMI≥30). Thereafter, we assessed clinical and metabolic data and cost of drug treatment in each category. Statistical analyses included group comparisons for continuous variables (parametric or non-parametric tests), Chi-square tests for differences between proportions, and multivariable regression analysis to assess the association between BMI and monthly cost of drug treatment. RESULTS: Although all groups showed comparable degree of glycometabolic control (FBG, HbA1c), we found significant differences in other metabolic control indicators. Total cost of drug treatment of hyperglycemia and associated cardiovascular risk factors (CVRF) increased significantly (p<0.001) with increment of BMI. Hyperglycemia treatment cost showed a significant increase concordant with BMI whereas hypertension and dyslipidemia did not. Despite different values and percentages of increase, this growing cost profile was reproduced in every participating country. BMI significantly and independently affected hyperglycemia treatment cost. CONCLUSIONS: Our study shows for the first time that BMI significantly increases total expenditure on drugs for T2D and its associated CVRF treatment in Latin America.

Health inequalities and the impact on the prevalence of cardiovascular risk factors and chronic complications in Argentina: a study on national risk factors surveys. / Desigualdades en salud, su impacto sobre la prevalencia de factores de riesgo cardiovascular y el desarrollo de sus complicaciones crónicas en Argentina: estudio sobre Encuesta Nacional de Factores de Riesgo.

BACKGROUND: In Argentina, there is evidence of health inequalities, measured both at the general level and also using income as a parameter of social status. However, few studies address the issue of health equality in chronic diseases such as cardiovascular risk factors. OBJECTIVE: To describe health inequalities, using cardiovascular risk factors as a tracer for chronic diseases in different areas of the country and over time. In addition, we aim to identify differences in the quality of care provided to people with cardiovascular risk factors, between 2005 and 2009. METHODS: This is an observational study, which used descriptive and quantitative methods. Data from the National Risk Factors Survey from 2005 and 2009 in the cohorts who have chronic diseases (hypertension, diabetes, dyslipidemia and overweight/obesity) were analyzed to assess associations between health status and several demographic, epidemiological and socioeconomic variables. Additionally, clinical and metabolic characteristics of people with diabetes and other cardiovascular risks factors were analyzed in 2005 and 2009 using the database Quality of Diabetes Care (QUALIDIAB). RESULTS: Cardiovascular risk factors are more frequent in people with lower socioeconomic status, regardless of the indicator. The inequalities detected showed the worst indicators in strata with lower education and income, with the same results both nationwide and separated by region. This inequalities were more pronounced in 2009, and their magnitude changed by region and cardiovascular risk factor. From 2005 to 2009, body mass index, blood glucose and HbA1c value increased. In contrast, both systolic blood pressure and triglycerides decreased, with no significant changes in total cholesterol and diastolic blood pressure. CONCLUSION: Cardiovascular risk factors present inequalities attributed to social status manifesting at both national and regional levels.

INTRODUCCIÓN: Argentina muestra evidencia de desigualdades en salud medida, tanto a nivel general como utilizando el ingreso como parámetro de posición social. Sin embargo, pocos estudios abordan la problemática de la equidad en salud a nivel de enfermedades crónicas como los factores de riesgo cardiovascular. OBJETIVO: Describir las desigualdades en salud utilizando como trazador de enfermedades crónicas a los factores de riesgo cardiovascular a nivel subnacional y su evolución temporal. Para complementar, se busca identificar las diferencias en la calidad de atención brindada a personas con factores de riesgo cardiovascular entre 2005 y 2009. MÉTODOS: Estudio observacional y cuantitativo basado en métodos descriptivos. Se analizó la Encuesta Nacional de Factores de Riesgo 2005 y 2009 para evaluar hipertensión, diabetes, dislipemia y sobrepeso/obesidad en las cohortes correspondientes, las asociaciones entre el estado de salud y diversas variables demográficas, epidemiológicas y socioeconómicas. Adicionalmente, y utilizando la base de datos del registro Quality of Diabetes Care (QUALIDIAB), se analizaron las características clínicas y metabólicas de las personas con diabetes y otros factores de riesgo cardiovascular en los años 2005 y 2009. RESULTADOS: Los factores de riesgo cardiovascular se presentan más frecuentemente en personas con menor posición socioeconómica, independientemente del indicador considerado. Las desigualdades detectadas mostraron peores indicadores en los estratos con educación e ingreso más bajo, manifestándose tanto a nivel nacional como regional. En general, son más acentuadas en el año 2009. Su magnitud varió según región y factor de riesgo cardiovascular considerado. De 2005 a 2009, se incrementan los valores de índice de masa corporal, glucemia y hemoglobina glicosilada, disminuyeron los de presión arterial sistólica y los triglicéridos, sin cambios significativos en el colesterol total y presión arterial diastólica. CONCLUSIONES: En nuestro medio, los factores de riesgo cardiovascular presentan desigualdades condicionadas por su posición social, manifestándose tanto a nivel nacional como regional.

Improving diabetes care at primary care level with a multistrategic approach: results of the DIAPREM programme.

AIM: To present results, 1 year postimplementation at primary care level, of an integrated diabetes care programme including systemic changes, education, registry (clinical, metabolic, and therapeutic indicators), and disease management (DIAPREM). METHODS: We randomly selected and trained 15 physicians and 15 nurses from primary care units of La Matanza County (intervention-IG) and another 15 physicians/nurses to participate as controls (control-CG). Each physician-nurse team controlled and followed up 10 patients with type 2 diabetes for 1 year; both groups used structured medical records. Patients in IG had quarterly clinical appointments, whereas those in CG received traditional care. Statistical data analysis included parametric/nonparametric tests according to data distribution profile and Chi-squared test for proportions. RESULTS: After 12 months, the dropout rate was significantly lower in IG than in CG. Whereas in IG HbA1c, blood pressure and lipid profile levels significantly decreased, no changes were recorded in CG. Drug prescriptions showed no significant changes in IG except a decrease in oral monotherapy. CONCLUSIONS: DIAPREM is an expedient and simple multistrategic model to implement at the primary care level in order to decrease patient dropout and improve control and treatment adherence, and quality of care of people with diabetes.

Multistrategic approach to improve quality of care of people with diabetes at the primary care level: Study design and baseline data.

AIM: To test the one year-post effect of an integrated diabetes care program that includes system changes, education, registry (clinical, metabolic and therapeutic indicators) and disease management (DIAPREM), implemented at primary care level, on care outcomes and costs. METHODS: We randomly selected 15 physicians and 15 nurses from primary care units of La Matanza County to be trained (Intervention-IG) and another 15 physicians/nurses to use as controls (Control-CG). Each physician-nurse team controlled and followed up 10 patients with type 2 diabetes for one year; both groups use structured medical data registry. Patients in IG had quarterly clinical appointments whereas those in CG received traditional care. DIAPREM includes system changes (use of guidelines, programmed quarterly controls and yearly visits to the specialist) and education (physicians' and nurses' training courses). Statistical data analysis included parametric/nonparametric tests according to data distribution profile and Chi-squared test for proportions. RESULTS: Baseline data from both groups showed comparable values and 20-30% of them did not perform HbA1c and lipid profile measurements. Majority were obese, 59% had HbA1C ≥7%, 86% fasting blood glucose ≥100mg/dL, 45%, total cholesterol ≥200mg/dL, and 92% abnormal HDL- and LDL-cholesterol values. Similarly, micro and macroangiopathic complications had not been detected in the previous year. Most patients received oral antidiabetic agents (monotherapy), and one third was on insulin (mostly a single dose of an intermediate/long-acting formulation). Most people with hypertension received specific drug treatment but only half of them reached target values; dyslipidemia treatment showed similar data. CONCLUSIONS: Baseline data demonstrated the need of implementing an intervention to improve diabetes care and treatment outcomes.

Prevención primaria de diabetes tipo 2 en Argentina: estudio piloto en la provincia de Buenos Aires / Primary prevention of type 2 diabetes in Argentina: Pilot study in the province of Buenos Aires

Intervenciones: Sobre estilo de vida, previenen el desarrollo de diabetes tipo 2 (DMT2) en personas con tolerancia a la glucosa o glucemia de ayunas alterada (TGA y GAA, respectivamente), aisladas o combinadas. Objetivo: Evaluar la efectividad de adoptar estilo de vida saludable sobre la manifestación clínica de DMT2 en personas con riesgo de desarrollarla. Metodología: Estudio prospectivo en participantes de 3 municipios de provincia de Buenos Aires (La Plata, Berisso y Ensenada), mediante cuestionario FINDRISC; quienes superen su puntaje de riesgo (≥ 13), realizarán prueba de tolerancia oral a la glucosa. El estudio incluirá a todas las personas con TGA/GAA que deseen participar y firmen un consentimiento informado, distribuidas en 2 grupos: a) intervención autoadministrada, y b) intervención intensificada (talleres de modalidad grupal mensuales sobre plan de alimentación saludable y práctica regular de actividad física 3 veces por semana). Ambos grupos tendrán un seguimiento de 2 años. Se utilizarán cuestionarios para evaluar bienestar, hábitos alimentarios y actividad física de cada participante al inicio del estudio y cada 6 meses durante el seguimiento. En ambos grupos se realizarán individualmente mediciones antropométricas y análisis de laboratorio a los 0, 12 y 24 meses. Igualmente, se evaluará la coste-efectividad de las estrategias implementadas. Resultados y conclusiones: Los resultados del estudio permitirán: a) demostrar la factibilidad y el costo de este tipo de programas: b) identificar genotipos de personas en riesgo facilitando intervenir en ellas precoz y eficientemente; c) definir si estas intervenciones también mejoran otros FRCV presentes; d) cuantificar las lesiones de microangiopatía (microaneurismas retinianos) en población con TGA/GAA, y e) identificar barreras y alianzas estratégicas interdisciplinarias e intersectoriales para la implementación efectiva de este tipo de programas.

Lifestyle interventions: Prevent/delay the development of type 2 diabetes (T2DM) in people with impaired glucose tolerance or impaired fasting blood glucose (IGT and IFG, respectively), alone or combined. Objective: To evaluate the effectiveness of adopting a healthy lifestyle on the clinical manifestation of T2DM in people at risk of its development. Methodology: A prospective study will be conducted, using the FINDRISC questionnaire, on participants selected from three municipalities of the Province of Buenos Aires (La Plata, Berisso and Ensenada). An oral glucose tolerance test will be performed on those participants who exceed their risk score (≥ 13). The study will include all people with IGT/ IFG who wish to participate and sign an informed consent form. They will be randomly divided into two groups: a) self-administered intervention and b) Intensified Intervention (monthly group sessions on healthy meal plan and weekly sessions of physical activity). Both groups will be followed-up for two years. Questionnaires will be used to assess welfare (WHO-5), eating habits, and physical activity of each participant at baseline and every six months of followup. Individual anthropometric measurements and laboratory analysis will be performed in both groups at 0, 12 and 24 months. The cost-effectiveness of the strategies implemented will also be assessed. Results and conclusions: The results of the study will allow to: a) demonstrate the feasibility and cost of such programs, b) identify genotypes of people at risk that would facilitate early implementation of effective prevention strategies; c) define whether these interventions would also improve other associated cardiovascular risk factors, d) Identify and quantify microangiopathy lesions (retinal micro-aneurysms) in a population with IGT/IFG, and e) identify barriers and interdisciplinary strategic alliances for effective implementation of such programs.

Frequency of self-monitoring blood glucose and attainment of HbA1c target values.

AIMS: Test strips for self-monitoring of blood glucose (SMBG) represent in Argentina, around 50 % of diabetes treatment cost; the frequency of their use is closely associated with hyperglycemia treatment. However, the favorable impact of SMBG on attainment of HbA1c goal in different treatment conditions remains controversial. We therefore attempted to estimate the relationship between use of SMBG test strips and degree of attainment of metabolic control in an institution of our social security subsector (SSS) in which provision is fully covered and submitted to a regular audit system. METHODS: Observational retrospective study using information of 657 patients with T2DM (period 2009-2010) from the database of the Diabetes and Other Cardiovascular Risk Factors Program (DICARO) of one institution of our SSS. DICARO provides-with an audit system-100 % coverage for all drugs and keeps records of clinical, metabolic and treatment data from every patient. RESULTS: The average monthly test strips/patient used for SMBG increased as a function of treatment intensification: Monotherapy with oral antidiabetic drugs (OAD) < combined OAD therapy < insulin treatment. In every condition, the number was larger in people with target HbA1c levels. Test strips represented the larger percentage of total prescription cost. CONCLUSIONS: In our population, the type of hyperglycemia treatment was the main driver of test strip use for SMBG; in every condition tested, targeted HbA1c values were associated with greater strip use. Patient education and prescription audit may optimize its use and treatment outcomes.

[Education of people with type 2 diabetes through peers with diabetes: is it cost effective?]. / Educación de personas con diabetes tipo 2: ¿es costo-efectiva su implementación a través de pares con diabetes?

INTRODUCTION: Inadequate quality of care provided to people with type 2 diabetes mellitus, generates a significant socioeconomic burden and a serious public health problem. Diabetes education through peers with diabetes is an alternative to that provided by professional educators (traditional education) which achieves non-inferior results. However, there is little evidence of cost-effectiveness of education trough peers over traditional education. OBJECTIVE: To evaluate cost-effectiveness of education of people with type 2 diabetes mellitus, during a year, by a team of professional educators (traditional education) versus education and support delivered by trained peers with diabetes. METHODS: Cost-effectiveness analysis based on a randomized prospective clinical study conducted in the city of La Plata, including 199 people with type 2 diabetes mellitus, divided in two groups:, one receiving traditional education and another receiving the same education but delivered by peer educators with type 2 diabetes mellitus. Change in glycosylated hemoglobin (HbA1c) was considered as a primary indicator of effectiveness and secondary indicators were others, such as body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol and triglyceride levels. The direct cost of each strategy was estimated based on resources used in the trial, evaluating three cost scenarios for peer education. The strength of the results was assessed by univariate sensitivity analysis. RESULTS: Cost per unit decrease (%) in HbA1c: traditional education: $2 621; peer education: $1 508, $1 779 y $2 071 for each of the three scenarios considered (scenario 1, scenario 2, scenario 3), respectively. For each $100 invested a decrease of 0.04% in the HbA1c with traditional education was achieved; and 0.07% in scenario 1; 0.06% in scenario 2 and 0.05% in scenario 3, with education delivered by peer educators. Sensitivity analysis showed the strength of the results. CONCLUSION: Education of type 2 diabetes mellitus patients through peers as a complement to control and treatment of the disease, is cost-effective compared to traditional education.

INTRODUCCIÓN : La inadecuada calidad de atención brindada a personas con diabetes tipo 2, genera un gran impacto socioeconómico y un grave problema de salud pública. La educación de estas personas a través de pares con diabetes mellitus es una alternativa, a la brindada por equipos profesionales (educación tradicional), que logra resultados no inferiores a esta última. Sin embargo, hay escasa evidencia de costo-efectividad de la educación a través de pares respecto de la tradicional. OBJETIVO: Evaluar la relación costo-efectividad de la educación de personas con diabetes tipo 2, durante un año por un equipo profesional (educación tradicional), versus educación y apoyo impartida por un par con diabetes mellitus (educación de pares). MÉTODOS: Análisis de costo-efectividad basado en un estudio clínico prospectivo aleatorizado, desarrollado en la ciudad de La Plata sobre 199 personas con diabetes tipo 2, organizados en dos grupos: uno que recibió educación tradicional y otro educación a través de pares con diabetes mellitus. Como indicador primario de efectividad se consideró el cambio en la hemoglobina glicosilada y como secundarios otros como índice de masa corporal, presión arterial sistólica, presión arterial diastólica, glucemia en ayunas, colesterol total y triglicéridos. Se estimó el costo directo de cada estrategia basándose en recursos utilizados en el estudio clínico y evaluándose tres escenarios de costos para la educación de pares. La robustez de los resultados se evaluó mediante análisis de sensibilidad univariado. RESULTADOS: El costo por unidad de descenso (%) de hemoglobina glicosilada con educación tradicional fue de $2621 pesos argentinos; y con educación a través de pares fue de $1508, $1779 y $2071 pesos argentinos, para cada uno de los tres escenarios considerados (escenario 1, escenario 2 y escenario 3), respectivamente. Por cada $100 pesos argentinos invertidos se logró descender 0,04% de hemoglobina glicosilada con la educación tradicional. Con la educación a través de pares los resultados fueron 0,07% en escenario 1; 0,06% en escenario 2 y 0,05% en escenario 3. El análisis de sensibilidad demostró la robustez de los resultados obtenidos. CONCLUSIÓN: La educación de personas con diabetes tipo 2 a través de pares, complementaria al control y tratamiento de la enfermedad, es costo efectiva respecto a la educación tradicional.

Self-monitoring of blood glucose: use, frequency drivers, and cost in Argentina.

Although test strips for self-monitoring of blood glucose (SMBG) represent around 50% of diabetes treatment cost in Argentina, little is known about their current use and relationship with different types of treatment. We therefore aimed to estimate the current use of test strips and identify the major use drivers and the percentage they represent of total prescription costs in 2 entities of the social security system (SSS) of Argentina. Observational retrospective study measuring test strip prescriptions delivered by pharmacies from the province of Buenos Aires (8115 records collected during 3 months provided by the Colegio de Farmacéuticos de la Provincia de Buenos Aires) of affiliates with type 2 diabetes (T2DM) from 2 large entities of the SSS system. The average monthly test strips/patient used for SMBG was 97.5 ± 70.1. This number varied according to treatment: monotherapy with oral antidiabetic drugs (OAD) < combined OAD therapy < insulin treatment. Test strips represented a higher percentage of the total prescription cost in people under OAD monotherapy (84.6%) and lower in those with insulin analogs (46.9%). In our population, the type of hyperglycemia treatment was the main driver of test strip use for SMBG and its impact on the total prescription cost depends on the kind of such treatment. Since it has been shown that patients' education and prescription audit can optimize test strip use and treatment outcomes, implementation of such strategies could appropriately support, optimize, and reduce ineffective test strip use in people with T2DM.
