Comparison of different definitions of metabolic syndrome and their relationship with cardiovascular risk estimation / Comparación de diferentes definiciones de síndrome metabólico y su relación con la estimación del riesgo cardiovascular

Abstract Introduction: Multiple definitions of metabolic syndrome (MS) are used in Peru, and there is currently no consensus on which definition should be used in clinical practice. Objectives: To compare cardiovascular disease (CVD) risk estimators, obtained using the ACC/AHA ASCVD Risk Calculator, and to assess their level of agreement with different definitions of MS in patients treated in Lima, Peru. Materials and methods: Analytical cross-sectional study. Medical records, collected through consecutive sampling, of 233 patients treated between October and December 2019 at the Hospital Nacional Hipólito Unanue, Lima, Peru, were reviewed. CVR risk was calculated using the online ACC/AHA ASCVD Risk Calculator, and the MS definitions of the WHO, NCEP-ATP III, IDF, AHA/NHLBI, JIS and ALAD were considered to compare CVD risk according to each definition. Agreement between the different MS definitions was calculated using the kappa coefficient based on the six levels of strength of agreement described by Landis and Koch. Results: The median CVD risk in patients with MS according to the definitions of the WHO, NCEP-ATP III, IDF, AHA/NHLBI, ALAD and JIS was 9.6 (3.9-20.35), 7.9 (3.1-18.6), 7.3 (3- 16.5), 7.8 (3-17.6), 7.1 (2.9-16.5), and 7.1 (3.1-16.5), respectively. The prevalence of MS according to JIS, IDF, ALAD, AHA/NHLBI, NCEP-ATP III and WHO definitions was 81.97%, 80.26%, 74.68%, 67.81%, 65.67%, and 51.14%, respectively. Agreement between the JIS criteria and the IDF, ALAD, NCEP-ATP III, and AHA/NHLBI criteria was 0.944, 0.787, 0.592, and 0.567, respectively, but it was 0.286 between the JIS criteria and the WHO criteria. Conclusions: In Peru, there are differences between CVD risk estimates depending on the MS definition used and considered in the present study, which may have an impact on the intensity of the therapeutic and preventive interventions performed in these patients.

Resumen Introducción. En Perú se usan múltiples definiciones de síndrome metabólico (SM); sin embargo, actualmente no hay un consenso sobre cuál definición usar en la práctica clínica. Objetivos. Comparar las estimaciones de riesgo cardiovascular (RCV), obtenidas mediante la calculadora de RCV de la ACC/AHA, y evaluar su grado de concordancia con diferentes definiciones de SM en pacientes atendidos en Lima, Perú. Materiales y métodos. Estudio transversal analítico. Se revisaron las historias clínicas, obtenidas por muestreo consecutivo, de 233 pacientes atendidos entre octubre y diciembre de 2019 en el Hospital Nacional Hipólito Unanue, Lima, Perú. El RCV se calculó mediante la calculadora virtual de RCV de la ACC/AHA y se consideraron las definiciones de SM de la OMS, NCEP-ATP III, IDF, AHA/NHLBI, JIS y ALAD para comparar el RCV según cada definición. La concordancia entre las distintas definiciones de SM se calculó mediante el coeficiente kappa con base en los seis niveles de fuerza de concordancia de Landis y Koch. Resultados. Las medianas de RCV en pacientes con SM según las definiciones de la OMS, NCEP-ATP III, IDF, AHA/NHLBI, ALAD y JIS fueron 9.6 (3.9-20.35), 7.9 (3.1-18.6), 7.3 (3-16.5), 7.8 (3-17.6), 7.1 (2.9-16.5) y 7.1 (3.1-16.5), respectivamente. La prevalencia de SM según las definiciones JIS, IDF, ALAD, AHA/NHLBI, NCEP-ATP III y OMS fue 81.97%, 80.26%, 74.68%, 67.81%, 65.67% y 51.14%, respectivamente. La concordancia entre las definiciones JIS e IDF, ALAD, NCEP-ATP III y AHA/NHLBI fue 0.944, 0.787, 0.592 y 0.567, respectivamente, pero entre la JIS y la OMS fue 0.286. Conclusiones. Existen diferencias entre las estimaciones de RCV según las distintas definiciones de SM usadas en Perú y consideradas en el presente estudio, lo que puede tener repercusiones en la intensidad de las intervenciones terapéuticas y preventivas realizadas en estos pacientes.

A Lifestyle Intervention During Pregnancy and Its Effects on Child Weight 2.5 Years Later.

AIM: The aim of this study was to evaluate if overweight and obesity in the offspring is reduced by a low-intensity antenatal primary care intervention with focus on diet and physical activity for pregnant women with obesity, comparing children to mothers receiving the intervention with children to mothers who did not. METHODS: This study is a follow-up of children 2.5 years of age after their mothers' participation in a non-randomised controlled intervention intending to limit gestational weight gain. All study participants received standard antenatal care. The intervention group received lifestyle support via motivational talks with midwife and support from dietician. Data on child weight were collected by medical records, letter and phone. RESULTS: There was no significant difference between the groups 2.5 years after intervention (International Obesity Task Force ISO-BMI 25 (child BMI corresponding to adult BMI of 25): 20% vs. 21%; ISO-BMI 30: 4.6% vs. 1.3%). The mother's BMI at the beginning of pregnancy significantly influenced child BMI at 2.5 years (r = 0.13, p = 0.014, r2 = 0.017). For each unit of increase in maternal BMI at enrollment, the probability of child ISO-BMI ≥ 25 increased by 7.5% (p = 0.021) and of ≥ 30, by 12.9% (p = 0.017). CONCLUSION: The frequency of overweight and obesity of the children at 2.5 years of age was significantly correlated to the mother's BMI, but not correlated to the mothers' participation in the antenatal lifestyle intervention. Thus, it seems important to address obesity and lifestyle issues before and between pregnancies. Trial registration The study has been registered at ClinicalTrials.gov, Identifier: NCT03147079.

SUMMARY: Obesity is a global, public health problem. Considered a systemic, multiorgan, metabolic and chronic inflammatory disease, with an excess of subcutaneous adipose tissue, which carries a greater risk of morbidity and mortality due to life cycles. To determine the general obesity trends according to demographic variables in Ecuador in the period 2014 - 2016. Population study, with 318,594 subjects diagnosed with general obesity. 77.2 % represented by women. The data were provided by the Ministry of Public Health of Ecuador according to province (n = 24), regions (Coast, Sierra, Amazon, and Insular), age groups (under 15, 15 to 19, 20 to 64, and over 65) and sex. Statistical analyzes of frequencies, percentage, incidence rate per 1.000 inhabitants, incidence rate ratio per year, in the total population, by sex and age group were performed. Microsoft Excel 16.44 soft- ware was used. Considering 95 % confidence intervals. In the period studied, the general obesity rate per 1.000 inhabitants was 6,5, being 3 times higher in women than in men. In 2016, the highest obesity incidence rates were reported, (6,38 per 1000 inhabitants). In addition, there is an obesity rate 2,38 times higher in the Insular region than in the Coast (95 % CI; 2.14-2.65). The data found are important, since it is the first study where these figures were analyzed, so it is relevant to consider them when carrying out disease prevention and health promotion.

Association between high blood pressure and fitness and fatness in adolescents / Presión arterial alta asociada con condición física y adiposidad en adolescentes

Abstract Introduction: Excess adiposity is considered the most important risk factor for high blood pressure (HBP) in children and adolescents. Objectives: To explore the association between HBP and overweight (OW) and abdominal obesity (AO), mediated by cardiorespiratory fitness (CRF). To analyze the combined effect of excess adiposity and CRF on HBP among a sample of school-aged children from Montería, Colombia. Materials and methods: Cross-sectional study conducted in a sample of 546 adolescents aged between 11 and 18 years from 14 randomly selected schools in Montería. Blood pressure, anthropometric, and fitness measures were evaluated by trained personnel using standardized protocols and instrumentation. The association of HBP with fitness and fatness was analyzed using logistic regression models. Results: HBP was associated with OW, AO and low CRF. The inclusion of CRF in this model did not attenuate the association between HBP and OW and between HPB and AO. Adolescents with higher adiposity and low CRF were more likely to have HBP compared with those with lower adiposity and high CRF. Moreover, it was found that excess adiposity and low CRF had an additive effect on the risk for HBP among the sample. Conclusion: HBP is a prevalent condition in children and adolescents from Montería, Colombia. HBP is significantly associated with OW, AO, and low CRF; therefore, it is necessary to implement initiatives to promote healthy habits aimed at this population in order to reduce the incidence rate of HBP in Colombian adolescents.

Resumen Introducción. El exceso de adiposidad es considerado como el factor de riesgo más importante para la presión arterial alta (PAA) en niños y adolescentes. Objetivos. Explorar la asociación entre PAA y sobrepeso (SP) y obesidad abdominal (OA), mediada por condición física cardiorrespiratoria (CFC), y analizar el efecto combinado de la adiposidad excesiva y la CFC en la PAA en una muestra de escolares de Montería, Colombia. Materiales y métodos. Estudio transversal realizado en 546 adolescentes con edades entre 11 y 18 años de 14 escuelas seleccionadas aleatoriamente en Montería. Se evaluó la presión arterial, los indicadores antropométricos y la condición física; las mediciones fueron realizadas por personal capacitado mediante el uso de protocolos e instrumentos estandarizados. La asociación de PAA con condición física y adiposidad fue analizada a través de modelos de regresión logística. Resultados. Se encontró una asociación entre PAA y SP, OA y baja CFC. La inclusion de la CFC en el modelo no atenuó la asociación entre PAA y SP y entre PAA y OA. Los adolescentes con mayor adiposidad y baja CFC fueron más propensos a presentar PAA que aquellos con menor adiposidad y alta CFC. Además, se observó que la presencia de adiposidad excesiva y baja CFC aumenta el riesgo de desarrollar PAA. Conclusión. La PAA es una condición prevalente en niños y adolescentes de Montería, además se encontró una asociación estádisticamente significativa entre PAA y SP, OA, y baja CFC, por lo que es necesario que en el país se implementen estrategias que promuevan hábitos saludables en escolares y permitan reducir la tasa de incidencia de PAA en esta población.

Analysis of physical fitness according to sex, age, body mass index and level of physical activity in Spanish elementary school students / Análisis de la condición física según sexo, edad, índice de masa corporal y nivel de actividad física en estudiantes de primaria en España

Abstract Introduction: Scientific evidence suggests that schoolchildren's quality of life is directly related to their physical fitness (PF). Objective: To analyze the physical fitness of elementary school students according to age, sex, body mass index (BMI) and level of physical activity (PA). Materials and methods: Cross-sectional and descriptive study conducted in 103 schoolchildren (aged 8-12 years) from Spain. PF and PA were measured using the ALPHA-fitness test battery and the Physician-based Assessment and Counseling for Exercise instrument, respectively. Participants were classified according to their level of PA (physically inactive vs. physically active) and their BMI (normal weight vs. overweight-obese). Parametric statistics were used for data analysis. Results: Male participants had a better level of PF. In addition, it was found that PF slightly increases as age increases, regardless of the sex. Normal weight or physically active schoolchildren had better aerobic capacity and a healthier body composition. Conclusion: Keeping optimal PF levels at any stage of life requires adopting a healthy lifestyle since childhood; therefore, it is necessary to encourage schoolchildren to do physical activity on their own.

Resumen Introducción. La evidencia científica sugiere que la calidad de vida de los escolares se relaciona de forma directa con el estado de su condición física (CF). Objetivo. Analizar la CF según edad, sexo, índice de masa corporal (IMC) y nivel de actividad física en estudiantes de primaria. Materiales y métodos. Se realizó un estudio descriptivo transversal con 103 escolares entre 8 y 12 años de España. La CF se midió mediante la batería ALPHA-Fitness y la actividad física, con el cuestionario Physician-based Assessment and Counseling for Exercise. Los participantes se categorizaron según su nivel de actividad física (no activos versus activos) y su IMC (normo-peso versus sobrepeso-obesidad). Para el análisis se aplicó estadística paramétrica. Resultados. Los varones tuvieron un mejor nivel de CF, pero en ambos sexos se observó un leve incremento de esta a medida que aumentaba la edad. Los escolares con normopeso o activos físicamente tuvieron una mejor capacidad aeróbica y una composición corporal más saludable. Conclusión. Mantener niveles óptimos de CF a lo largo de la vida requiere de la adopción de un estilo de vida saludable desde la infancia, por tanto, es necesario promover la práctica autónoma de actividad física en los escolares.

Influence of maternal obesity on Bishop Score and failed induction of labour: A retrospective cohort study in a regional tertiary centre.

BACKGROUND: Maternal obesity is a growing health concern that has previously been associated with increased need for induction of labour (IOL) and caesarean section (CS) rates. Currently, limited evidence explores the influence of maternal body mass index (BMI) on Bishop Score (BS) and outcome of IOL. This study hypothesises that maternal obesity will lead to a lower BS at presentation, higher rates of failed IOL, and increased CS rates. AIMS: To explore the influence of maternal obesity on BS and likelihood of failed IOL. METHODS: A retrospective cohort analysis was conducted of all live, term, singleton, cephalic deliveries initiated with IOL across normal BMI (18.00-24.99), overweight BMI (25.00-29.99), and obese BMI (>30.00) at the Townsville Hospital and Health Service (THHS) between July 2011 to June 2016. Student's t-test, χ2 test, and binary logistic regression were used for statistical analysis. BS and failed IOL, defined as CS with cervical dilatation <3 cm, were the primary outcome measures. Delivery mode was the secondary outcome measure. RESULTS: A total of 1543 women were included, 678 with normal BMI, 370 with overweight BMI, and 495 with obese BMI. Obese women are more likely to have a low BS (<5) at presentation (unadjusted odds ratio (OR) 1.5 (1.1-2.0), P < 0.05), an increased rate of failed IOL (adjusted OR (aOR) 1.6 (1.0-2.5), P < 0.05) and increased CS rate (aOR 1.1 (1.0-1.9), P < 0.05), compared to normal weight women. CONCLUSIONS: Maternal obesity is associated with a lower BS, more difficult IOL process, and increased risk of failed IOL and CS.

Use of a mobile social networking intervention for weight management: a mixed-methods study protocol.

INTRODUCTION: Obesity and physical inactivity are major societal challenges and significant contributors to the global burden of disease and healthcare costs. Information and communication technologies are increasingly being used in interventions to promote behaviour change in diet and physical activity. In particular, social networking platforms seem promising for the delivery of weight control interventions.We intend to pilot test an intervention involving the use of a social networking mobile application and tracking devices (Fitbit Flex 2 and Fitbit Aria scale) to promote the social comparison of weight and physical activity, in order to evaluate whether mechanisms of social influence lead to changes in those outcomes over the course of the study. METHODS AND ANALYSIS: Mixed-methods study involving semi-structured interviews and a pre-post quasi-experimental pilot with one arm, where healthy participants in different body mass index (BMI) categories, aged between 19 and 35 years old, will be subjected to a social networking intervention over a 6-month period. The primary outcome is the average difference in weight before and after the intervention. Secondary outcomes include BMI, number of steps per day, engagement with the intervention, social support and system usability. Semi-structured interviews will assess participants' expectations and perceptions regarding the intervention. ETHICS AND DISSEMINATION: Ethics approval was granted by Macquarie University's Human Research Ethics Committee for Medical Sciences on 3 November 2016 (ethics reference number 5201600716).The social network will be moderated by a researcher with clinical expertise, who will monitor and respond to concerns raised by participants. Monitoring will involve daily observation of measures collected by the fitness tracker and the wireless scale, as well as continuous supervision of forum interactions and posts. Additionally, a protocol is in place to monitor for participant misbehaviour and direct participants-in-need to appropriate sources of help.

Effects of high-intensity interval training on the anthropometric profile of overweight and obese adult women / Efectos del entrenamiento físico intervalado de alta intensidad sobre el perfil antropométrico de mujeres adultas con sobrepeso u obesidad

Abstract Introduction: Sedentary lifestyle, overweight and obesity in adult women have high prevalence. Objective: To determine the effects of a high intensity interval training program on the anthropometric profile of overweight or obese women. Materials and methods: 24 adult women, including 16 with overweight and 8 with obesity, between 26 and 49 years of age, were selected to participate in a two month high intensity training program (three sessions per week). Weight, height, BMI, muscle mass percentage, and fat mass and visceral fat percentages were assessed. Results: The adherent group (≥75% assistance) was composed by 16 participants, while the non-adherent group (assistance <75%), by 8 participants. No significant differences were found among both groups previous to and after the intervention (p≥0.05).The non-adherent group did not show any significant change, while the adherent group improved (p<0.05) their variables of weight (p<0.001), BMI (p<0.001), fat mass percentage (p<0.001), muscle mass percentage (p<0.001) and visceral fat percentage (p=0.020) after the intervention. Conclusions: The training program improved the anthropometric profile of the participants without requiring specialized equipment or involving high costs, thus, this procedure is recommended for the treatment of malnutrition by excess in this type of population.

Conclusiones. El programa de entrenamiento mejoró el perfil antropométrico de las participantes sin requerir implementos ni costos elevados para su desarrollo, por lo que es un procedimiento recomendable para el tratamiento de la malnutrición por exceso.

Clinical phenotypes in patients with knee osteoarthritis: a study in the Amsterdam osteoarthritis cohort.

OBJECTIVE: To identify and validate previously established phenotypes of knee osteoarthritis (OA) based on similarities in clinical patient characteristics. METHODS: Knee OA patients (N = 551) from the Amsterdam OA (AMS-OA) cohort provided data. Four clinical patient characteristics were assessed: upper leg muscle strength, body mass index (BMI), radiographic severity (Kellgren/Lawrence [KL] grade), and depressive mood (the Hospital Anxiety and Depression Scale [HADS] questionnaire). Cluster analysis was performed to identify the optimal number of phenotypes. Differences in clinical characteristics between the phenotypes were analyzed with ANOVA. RESULTS: Cluster analysis identified five phenotypes of knee OA patients: "minimal joint disease phenotype", "strong muscle strength phenotype", "severe radiographic OA phenotype", "obese phenotype", and "depressive mood phenotype". CONCLUSIONS: Among patients with knee OA, five phenotypes were identified based on four clinical characteristics. To a high degree, the results are a replication of earlier findings in the OA Initiative, indicating that these five phenotypes seem a stable, valid, and clinically relevant finding.
