Forty years of struggle in North Carolina: Workplace segregation and fatal occupational injury rates.

OBJECTIVE: To assess workplace segregation in fatal occupational injury from 1992 to 2017 in North Carolina. METHODS: We calculated occupational fatal injury rates within categories of occupation, industry, race, age, and sex; and estimated expected numbers of fatalities among Black and Hispanic male workers had they experienced the rates of White male workers. We also estimated the contribution of workforce segregation to disparities by estimating the expected number of fatalities among Black and Hispanic male workers had they experienced the industry and occupation patterns of White male workers. We assessed person-years of life-lost, using North Carolina life expectancy estimates. RESULTS: Hispanic workers contributed 32% of their worker-years and experienced 58% of their fatalities in construction. Black workers were most overrepresented in the food manufacturing industry. Hispanic males experienced 2.11 (95% CI: 1.86-2.40) times the mortality rate of White males. The Black-White and Hispanic-White disparities were widest among workers aged 45 and older, and segregation into more dangerous industries and occupations played a substantial role in driving disparities. Hispanic workers who suffered occupational fatalities lost a median 47 life-years, compared to 37 among Black workers and 36 among White workers. CONCLUSIONS: If Hispanic and Black workers experienced the workplace safety of their White counterparts, fatal injury rates would be substantially reduced. Workforce segregation reflects structural racism, which also contributes to mortality disparities. Root causes must be addressed to eliminate disparities.

Effectiveness of an Interactive mHealth App (EVITE) in Improving Lifestyle After a Coronary Event: Randomized Controlled Trial.

BACKGROUND: Coronary heart disease is one of the leading causes of mortality worldwide. Secondary prevention is essential, as it reduces the risk of further coronary events. Mobile health (mHealth) technology could become a useful tool to improve lifestyles. OBJECTIVE: This study aimed to evaluate the effect of an mHealth intervention on people with coronary heart disease who received percutaneous coronary intervention. Improvements in lifestyle regarding diet, physical activity, and smoking; level of knowledge of a healthy lifestyle and the control of cardiovascular risk factors (CVRFs); and therapeutic adherence and quality of life were analyzed. METHODS: This was a randomized controlled trial with a parallel group design assigned 1:1 to either an intervention involving a smartphone app (mHealth group) or to standard health care (control group). The app was used for setting aims, the self-monitoring of lifestyle and CVRFs using measurements and records, educating people with access to information on their screens about healthy lifestyles and adhering to treatment, and giving motivation through feedback about achievements and aspects to improve. Both groups were assessed after 9 months. The primary outcome variables were adherence to the Mediterranean diet, frequency of food consumed, patient-reported physical activity, smoking, knowledge of healthy lifestyles and the control of CVRFs, adherence to treatment, quality of life, well-being, and satisfaction. RESULTS: The study analyzed 128 patients, 67 in the mHealth group and 61 in the control group; most were male (92/128, 71.9%), with a mean age of 59.49 (SD 8.97) years. Significant improvements were observed in the mHealth group compared with the control group regarding adherence to the Mediterranean diet (mean 11.83, SD 1.74 points vs mean 10.14, SD 2.02 points; P<.001), frequency of food consumption, patient-reported physical activity (mean 619.14, SD 318.21 min/week vs mean 471.70, SD 261.43 min/week; P=.007), giving up smoking (25/67, 75% vs 11/61, 42%; P=.01), level of knowledge of healthy lifestyles and the control of CVRFs (mean 118.70, SD 2.65 points vs mean 111.25, SD 9.05 points; P<.001), and the physical component of the quality of life 12-item Short Form survey (SF-12; mean 45.80, SD 10.79 points vs mean 41.40, SD 10.78 points; P=.02). Overall satisfaction was higher in the mHealth group (mean 48.22, SD 3.89 vs mean 46.00, SD 4.82 points; P=.002) and app satisfaction and usability were high (mean 44.38, SD 6.18 out of 50 points and mean 95.22, SD 7.37 out of 100). CONCLUSIONS: The EVITE app was effective in improving the lifestyle of patients in terms of adherence to the Mediterranean diet, frequency of healthy food consumption, physical activity, giving up smoking, knowledge of healthy lifestyles and controlling CVRFs, quality of life, and overall satisfaction. The app satisfaction and usability were excellent. TRIAL REGISTRATION: Clinicaltrials.gov NCT04118504; https://clinicaltrials.gov/study/NCT04118504.

Impact of mHealth application on adherence to cardiac rehabilitation guidelines after a coronary event: Randomised controlled clinical trial protocol.

Background: Coronary disease is the main cause of death around the world. mHealth technology is considered attractive and promising to promote behavioural changes aimed at healthy lifestyle habits among coronary patients. The purpose of this study is to evaluate the efficacy of an mHealth intervention regarding improved results in secondary prevention in patients after an acute myocardial infarction (AMI) or angina in terms of lifestyle, clinical variables and therapeutic compliance. Methods: Randomised clinical trial with 300 patients who underwent a percutaneous coronary intervention (PCI) with stent implant. They will be assigned to either the mHealth group, subject to a self-monitored educational intervention involving an internet application installed on their mobile phone or tablet, or to a control group receiving standard healthcare (150 patients in each arm). The primary outcome variables will be adherence to the Mediterranean diet, physical activity, smoking, therapeutic compliance, knowledge acquired, user-friendliness and satisfaction with the application. Measurements of blood pressure, heart rate, body weight, waist circumference (WC) and the 6-min walk test will be taken. Furthermore, the blood lipid profile, glucose and HbA1c will be evaluated. Clinical interview will be conducted, and validated questionnaires completed. The primary quantitative results will be compared using an analysis of covariance adjusted for age and sex. A multivariate analysis will be performed to examine the association of the intervention with lifestyle habits, the control of cardiovascular risk factors (CDRFs) and the results after the hospital discharge (major adverse events, treatment compliance and lifestyle). Conclusions: The study will provide evidence about the effectiveness of an mHealth intervention at improving the lifestyle of the participants and could be offered to patients with coronary disease to complement existing services. Trial registration: NCT05247606. [https://ClinicalTrials.gov]. 21/02/2022.

Twenty-five year occupational homicide mortality trends in North Carolina: 1992-2017.

INTRODUCTION: Determining industry of decedents and victim-perpetrator relationships is crucial to inform and evaluate occupational homicide prevention strategies. In this study, we examine occupational homicide rates in North Carolina (NC) by victim characteristics, industry and victim-perpetrator relationship from 1992 to 2017. METHODS: Occupational homicides were identified from records of the NC Office of the Chief Medical Examiner system and the NC death certificates. Sex, age, race, ethnicity, class of worker, manner of death, victim-perpetrator relationship and industry were abstracted. Crude and age-standardised homicide rates were calculated as the number of homicides that occurred at work divided by an estimate of worker-years (w-y). Rate ratios and 95% CIs were calculated, and trends over calendar time in occupational homicide rates were examined overall and by industry. RESULTS: 456 homicides over 111 573 049 w-y were observed. Occupational homicide rates decreased from 0.82 per 100 000 w-y for the period 1992-1995 to 0.21 per 100 000 w-y for the period 2011-2015, but increased to 0.32 per 100 000 w-y in the period 2016-2017. Fifty-five per cent (252) of homicides were perpetrated by strangers. Taxi drivers experienced an occupational homicide rate that was 110 times (95% CI 76.52 to 160.19) the overall occupational homicide rate in NC; however, this rate declined by 76.5% between 1992 and 2017. Disparities were observed among workers 65+ years old, racially and ethnically minoritised workers and self-employed workers. CONCLUSION: Our findings identify industries and worker demographics that experienced high occupational homicide fatality rates. Targeted and tailored mitigation strategies among vulnerable industries and workers are recommended.

25-Year fatal workplace suicide trends in North Carolina: 1992-2017.

BACKGROUND: Suicide is a serious public health problem in the United States, but limited evidence is available investigating fatal suicides at work. There is a substantial need to characterize workplace suicides to inform suicide prevention interventions and target high-risk settings. This study aims to examine workplace suicide rates in North Carolina (NC) by worker characteristics, means of suicide used, and industry between 1992 and 2017. METHODS: Fatal workplace suicides were identified from records of the NC Office of the Chief Medical Examiner system and the NC death certificate. Sex, age, race, ethnicity, class of worker, manner of death, and industry were abstracted. Crude and age-standardized homicide rates were calculated as the number of suicides that occurred at work divided by an estimate of worker-years (w-y). Rate ratios and 95% confidence intervals (CIs) were calculated, and trends over calendar time for fatal workplace suicides were examined overall and by industry. RESULTS: 81 suicides over 109,464,430 w-y were observed. Increased rates were observed in workers who were male, self-employed, and 65+ years old. Firearms were the most common means of death (63%) followed by hanging (16%). Gas service station workers experienced the highest fatal occupational suicide rate, 11.5 times (95% CI: 3.62-36.33) the overall fatal workplace suicide rate, followed by Justice, Public Order, and Safety workers at 3.23 times the overall rate (95% CI: 1.31-7.97). CONCLUSION: Our findings identify industries and worker demographics that were vulnerable to workplace suicides. Targeted and tailored mitigation strategies for vulnerable industries and workers are recommended.

Therapeutic Exercise on Metabolic and Renal Outcomes in Patients with Chronic Kidney Disease: A Narrative Review.

BACKGROUND: Chronic kidney disease (CKD) affects 11-13% of the world population. The main risk factors for CKD include diabetes, hypertension, and obesity. Metabolic syndrome (MS) is associated with the onset of CKD in the nondiabetic population. Obesity and MS are also risk factors for a worse progression of established CKD. Therapeutic exercise is an effective option to treat and manage obesity, MS, and diabetes in the general population. However, the evidence on the effect of exercise on patients with CKD, obesity, and MS is scarce. SUMMARY: We evaluated available evidence on the effect of therapeutic exercise in patients with CKD, excluding dialysis, particularly in improving the metabolic risk factors and main renal outcomes: renal function loss and albuminuria/proteinuria. This review includes prospective studies and clinical trials. A total of 44 studies were analysed in 1,700 subjects with renal disease (2-5), including patients with renal transplantation. Most studies did not prove a major effect of exercise on albuminuria/proteinuria, glomerular filtration rate (GFR), obesity, or MS. These results are intriguing and deserve attention. The exploratory nature of most studies, including a low number of cases and short follow-up, might explain the lack of efficacy of exercise in our analysis. Specific aspects like the type of exercise, frequency, intensity, duration, accommodation during follow-up, individualization, safety, and adherence are crucial to the success of therapeutic exercise. The beneficial role of exercise in patients with CKD remains to be determined. KEY MESSAGES: Key messages of this review are as follows. (1) The effect of therapeutic exercise on renal and metabolic outcomes in patients with CKD remains to be determined. (2) According to the evidence selected, therapeutic exercise seems to be safe to treat patients with CKD. (3) Most studies are exploratory by nature, with results that need further investigation. (4) Therapeutic exercise is a complex procedure that must be specifically designed to treat patients with CKD.

Forty-year trends in fatal occupational injuries in North Carolina.

BACKGROUND: We describe progress in the control of deaths on-the-job due to fatal occupational injury in North Carolina over the period 1978-2017. METHODS: Forty years of information on fatal occupational injuries in North Carolina has been assembled from medical examiners' reports and death certificates, supplemented by newspaper and police reports. Cases were defined as unintentional fatal occupational injuries among adults. Annual estimates of the population at risk were derived from US Census data, and rates were quantified using Poisson regression methods. RESULTS: There were 4434 eligible deaths. The unintentional fatal occupational injury rate at the beginning of the study period was more than threefold the rate at the end of the study. The fatal occupational injury rate among men declined from 9.6 per 100,000 worker-years in the period 1978-1982 to 3.1 per 100,000 worker-years in the period 2013-2017. The fatal occupational injury rate among women declined from 0.3 per 100,000 worker-years in the period 1978-1981 to 0.1 per 100,000 worker-years in the period 2013-2017. Declines in rates were observed for young adults as well as older workers and were observed across all major industry categories. Average annual declines in rates were greatest in those industries and occupations that had the highest fatal injury rates at the start of the study period. CONCLUSIONS: The substantial decline in fatal injury rates underscores the importance of injury prevention and demonstrates the ability to make meaningful reductions in unintentional fatal injury.

Assessment of an intervention for preventing pediatric overweight and obesity through the World Café technique: A qualitative study.

PURPOSE: To evaluate the self-reported perspectives of participants involved in the Previene Cádiz intervention for preventing pediatric overweight and obesity. DESIGN AND METHODS: This qualitative study collected information through the World Café technique. A purposive sample of 40 participants was used, of which 14 were schoolchildren, 12 were teachers, and 14 were parent volunteers. The data were segmented, and concepts were created and grouped into dimensions and categories. RESULTS: The participants confirmed they had learned new information and behaviors about healthy habits. Parental awareness was considered a crucial and necessary element in changing family habits; therefore, increasing the motivation of family members was deemed a critical task in public health interventions conducted in school settings. DISCUSSION: Despite the suitability of qualitative methodology to evaluate the perceptions of the main players in an educational intervention, scientific literature is scarce. Obtaining information from the educational community about an intervention is not always easy, so the perspectives of teachers, students, and families about the Previene Cádiz intervention through the World Café approach is considered a relevant contribution. CONCLUSIONS: The participants considered the intervention positive in terms of learning and fostering increased knowledge, awareness, and healthy behaviors. PRACTICE IMPLICATIONS: Future interventions should encourage the active participation of all social groups involved, integrating dynamic and collaborative training activities that are acceptable to all participants.

Fatal occupational injuries in North Carolina, 1992-2017.

OBJECTIVES: After declining for several decades, fatal occupational injury rates have stagnated in the USA since 2009. To revive advancements in workplace safety, interventions targeting at-risk worker groups must be implemented. Our study aims to identify these at-risk populations by evaluating disparities in unintentional occupational fatalities occurring in North Carolina (NC) from 1992 to 2017. METHODS: Our retrospective cohort study drew on both the NC Office of the Chief Medical Examiner system and the NC death certificate data system to identify unintentional fatal occupational injuries occurring from 1992 to 2017. Unintentional fatal occupational injury rates were reported across industries, occupations and demographic groups, and rate ratios were calculated to assess disparities. RESULTS: Among those aged 18 and older, 2645 unintentional fatal occupational injuries were identified. Fatal occupational injury rates declined by 0.82 injuries/100 000 person-years over this period, falling consistently from 2004 to 2009 and increasing from 2009 to 2017. Fatal injury rates were highest among Hispanic workers, who experienced 2.75 times the fatal injury rate of non-Hispanic White workers (95% CI 2.42 to 3.11) and self-employed workers, who experienced 1.44 times the fatal injury rate of private workers (95% CI 1.29 to 1.60). We also observed that fatal injury rates increased with age group and were higher among male relative to female workers even after adjustment for differential distributions across occupations. CONCLUSIONS: The decline in unintentional fatal occupational injury rates over this period is encouraging, but the increase in injury rate after 2009 and the large disparities between occupations, industries and demographic groups highlight the need for additional targeted safety interventions.

Disparities in Fatal Occupational Injury Rates in North Carolina, 1978-2017: Comparing Nonmanagerial Employees to Managers.

BACKGROUND: We examined fatal occupational injuries among private-sector workers in North Carolina during the 40-year period 1978-2017, comparing the occurrence of fatal injuries among nonmanagerial employees to that experienced by managers. METHODS: We estimated a standardized fatal occupational injury ratio by inverse probability of exposure weighting, taking nonmanagerial workers as the target population. When this ratio measure takes a value greater than unity it signals settings in which nonmanagerial employees are not provided as safe a work environment as that provided for managers. RESULTS: Across all industries, nonmanagerial workers in North Carolina experienced fatal occupational injury rates 8.2 (95% CI = 7.0, 10.0) times the rate experienced by managers. Disparities in fatal injury rates between managers and the employees they supervise were greatest in forestry, rubber and metal manufacturing, wholesale trade, fishing and extractive industries, and construction. CONCLUSIONS: The results may help focus discussion about workplace safety between labor and management upon equity, with a goal of providing a work environment for nonmanagerial employees as safe as the one provided for managers.

Design of a Nutritional Survey to Detect High Dietary Salt Intakes and Its Usefulness in Primary Care Compared to 24-Hour Urine Sodium Determination.

Many population studies report salt intakes that exceed the WHO recommendation (2 g/day of Na+ or 5 g/day of salt). We do not have tools for detecting high salt intakes that are easy to apply in primary health care (PHC). We propose the development of a survey to screen for high salt intake in PHC patients. A cross-sectional study of 176 patients determines the responsible foods, and a study of 61 patients studies the optimal cut-off point and discriminant ability (ROC curve). We assessed the salt intake using a food frequency questionnaire and a 24 h dietary recall and used a factor analysis to identify the foods with the highest contribution to be included in a high intake screening questionnaire. We used 24 h urinary sodium as a gold standard. We identified 38 foods and 14 factors representing a high intake, explaining a significant proportion of the total variance (50.3%). Significant correlations (r > 0.4) were obtained between nutritional survey scores and urinary sodium excretion, allowing us to detect patients who exceed salt intake recommendations. For sodium excretion ≥ 2.4 g/day, the survey has a sensitivity of 91.4%, a specificity of 96.2% and an area under the curve of 0.94. For a prevalence of high consumption of 57.4%, the positive predictive value (PPV) was 96.9% and the negative predictive value (NPV) was 89.2%. We developed a screening survey for subjects with a high probability of high salt intake in primary health care, which could contribute to the reduction in diseases associated with this consumption.

Correlaciones entre la ingesta de sal en la dieta y la eliminación de sodio en la orina de 24 h en una muestra de población urbana de Cáceres / Correlations between dietary salt intake and 24-h urine sodium excretion in a sample of the urban population of Cáceres

Objetivo: La ingesta excesiva de sal se asocia a mayores cifras de tensión arterial y prevalencia de enfermedades cardiovasculares. La OMS recomienda consumir menos de 5 g/día de sal (equivalente a 2 g de Na+/día). Identificar alimentos y comportamientos con mayor contribución al exceso de aporte facilitaría el consejo dietético preventivo. Diseño: Estudio observacional. Sitio: Centro de Salud Urbano en Cáceres. Medidas principales: Estimamos el consumo de sal mediante dos cuestionarios de frecuencia de consumo de alimentos (CFA), uno genérico y otro con alimentos con elevado contenido en Na+, y encuesta recordatoria de 24 h. Empleamos el programa Evalfinut para la valoración nutricional de la dieta. Analizamos correlaciones entre ingesta estimada de sal y eliminación de sodio en orina de 24 h (gold standard). Resultados: El 92% de la muestra presenta consumos superiores a las recomendaciones con ingestas equivalentes a 9,5 g/día de sal (3,7 g/día de Na+). Cuando la ingesta de sodio se determina por el cociente Na+/K+, el 79,54% tiene ingestas elevadas. La eliminación de sodio sigue una tendencia ligeramente creciente con el IMC. La percepción de consumo de sal es baja, el 56,3% lo considera «adecuado»; el 32,4% añade sal a los alimentos una vez servidos. Los CFA infraestiman la ingesta de Na+ y encuestas dirigidas aportan valores más elevados. La correlación entre CFA y eliminación urinaria de Na+ es débil. Conclusión: Debemos reducir la ingesta de sal aumentando la percepción del consumo, mejorando el conocimiento sobre el contenido de sal en alimentos e identificando a pacientes diana del consejo sanitario.(AU)

Objective: Excessive salt intake is associated with higher levels of AHT and prevalence of cardiovascular diseases. WHO recommends consuming less than 5 g/day of salt (equivalent to 2 g Na+/day). Identifying foods and behaviours with greater contribution to excess intake would facilitate preventive dietary advice. Design: Observational study. Site: Urban Health Center in Cáceres. Main measurements: We estimated salt consumption using two food consumption frequency (FFQ) questionnaires, one generic and one with high Na+ content, and a 24 h follow-up survey. We use the Evalfinut program for nutritional evaluation of the diet. We analyzed correlations between estimated salt intake and 24-h urine sodium elimination (gold standard). Results: 92% of the population had consumption higher than the recommendations with intakes equivalent to 9.5 g/day of salt (3.7 g/d of Na+). When sodium intake is determined by the Na+/K+ ratio, 79.54% have high intakes. Sodium elimination follows a slightly increasing trend with BMI. The perception of salt consumption is low, 56.3% consider it “adequate”. 32.4% add salt to food once served. FFQ underestimate Na+ intake and targeted surveys provide higher values. The correlation between FFQ and Na+ urinary elimination is weak. Conclusion: We must reduce salt intake by increasing the perception of consumption, improving knowledge about the salt content in food and identifying target patients of the health council.(AU)

[Social media and cyberbullying in eating disorders]. / Redes sociales y ciberacoso en los trastornos de la conducta alimentaria.

Introduction: Eating disorders (ED) are a multifactorial pathology. In their origin multiple variables are involved to which nowadays a possible enhancing factor is added: the diffusion and promotion of the culture of thinness and the apology of ED through the social media (SM) used by the youngest people. Through the feedback tools of the social networks (likes, comments, visits, retweets, etc.) and the elements of comparison between equals of the most visual SMs, many users come to develop risk behaviours that in turn give feedback to others. In addition, a sense of belonging to a group or tribe is created through communities whose members feel supported and where very restrictive diets are shared in an affective way, as well as ways of hiding these and other behaviours from those who do not belong to the group; both elements make it difficult for professionals and the family to intervene. Due to the extensive use of SMs, the rapid dissemination of all that is published, and the limited control over shared content, it is virtually impossible to control those sites that advocate and promote behaviours that contribute to the development or maintenance of ED. Cyberbullying or intimidation through digital technologies often uses body image criticisms that damage the self-esteem of the most vulnerable. This cyberbullying is a factor increasingly present in young people who have suffered an ED. The key to prevention is considered to be media literacy in the use of SM, as well as parental supervision of the youngest. People at risk or who have already been diagnosed with ED find in these networks the social support they seek but are biased towards risk behaviours, when it is possible for health professionals to use them to the benefit of promoting healthy habits and for recovery from these disorders.

Introducción: Los trastornos de la conducta alimentaria (TCA) son una patología multifactorial. En su inicio están implicadas múltiples variables a las que se les suma hoy en día un posible potenciador: la difusión y promoción de la cultura de la delgadez y la apología de los TCA a través de las redes sociales (RR. SS.) usadas por los más jóvenes. A través de las herramientas de feedback de las redes (likes, comments, visitas, retweets, etc.) y los elementos de comparación entre iguales de las RR. SS. más visuales, muchos usuarios llegan a desarrollar conductas de riesgo que a su vez retroalimentan a otros. Por otra parte, se crea la sensación de pertenencia a un grupo o tribu a través de comunidades cuyos miembros se sienten apoyados y donde se comparten de forma afectiva dietas muy restrictivas, así como formas de ocultarlas y otras conductas a quienes no pertenecen al grupo; ambos elementos dificultan la intervención por parte de los profesionales y la familia. Debido al uso extensivo de las RR. SS., a la rápida difusión de todo aquello que se publica y al escaso control que hay sobre el contenido que se comparte, resulta prácticamente imposible controlar los sitios donde se hace apología y se promueven las conductas que contribuyen al desarrollo o mantenimiento de los TCA. El ciberacoso o intimidación por medio de tecnologías digitales utiliza con frecuencia críticas sobre la imagen corporal que dañan la autoestima de los más vulnerables, y es un factor cada vez más presente en los jóvenes que han padecido un TCA. Se considera que la clave de la prevención reside en la alfabetización mediática del uso de las RR. SS., así como la supervisión parental de los más jóvenes. Las personas en riesgo o ya diagnosticadas de TCA encuentran en estas redes el apoyo social que buscan, pero sesgado hacia las conductas de riesgo, cuando sería posible explotarlas en beneficio de la promoción de hábitos saludables y para la recuperación de estos trastornos.

[Advertising and the media in eating disorders]. / Publicidad y medios de comunicación en los trastornos de la conducta alimentaria.

Introduction: The media, by means of advertising, convey an ideal of unreal beauty associated with positive traits such as popularity, esteem, acceptance, intelligence, etc. This can be one of the factors that compromise emotional and physical health, being responsible for creating unrealistic expectations and body dissatisfaction, and exerting a very important influence on the triggering or maintenance of bad eating habits that can lead to eating disorders. The youngest population has a low capacity to anticipate the harmful effects of certain messages with commercial interests, and this requires implementing preventive programs based on media education, accompanied by modeling in the family nucleus to promote a healthy lifestyle.

Introducción: Los medios de comunicación, a través de la publicidad, transmiten un ideal de belleza no real asociado con rasgos positivos como popularidad, aprecio, aceptación, inteligencia, etc. Esto puede constituir uno de los factores que comprometen la salud emocional y física, siendo responsables de crear expectativas poco realistas e insatisfacción corporal y ejerciendo una influencia muy destacada en el desencadenamiento o mantenimiento de los malos hábitos alimentarios que pueden abocar en trastornos de la conducta alimentaria. La población más joven tiene una baja capacidad para prever los efectos nocivos de ciertos mensajes con intereses comerciales, por lo que se requiere la puesta en marcha de programas preventivos basados en la educación mediática, acompañada de un modelado del núcleo familiar en el que se promueva un estilo de vida saludable.

[Characterization, epidemiology and trends of eating disorders]. / Caracterización, epidemiología y tendencias de los trastornos de la conducta alimentaria.

Introduction: Background: eating disorders are a group of conditions in which negative beliefs about food, body shape, and body weight together with behaviors such as restricted food intake, binge eating, excessive exercise, self-induced vomiting, and use of laxatives. They can become serious, affect quality of life, and lead to multiple physical and even psychiatric complications with a fatal outcome. The purpose of this chapter is to describe the characteristics, epidemiology, and trends of eating disorders with updated information based on the most recent publications. Methods: we conducted a systematic literature search in Medline, EMBASE, Cochrane, and Web of Science. The search terms were "anorexia nervosa", "bulimia nervosa", "binge eating disorders" and "epidemiology" both in titles and in abstracts. Results and conclusions: EDs generally occur in adolescents and young adults. The best characterized TCAs are anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (TA). Prevalence studies indicate wide differences by age group and sex, much higher in young women (NA, 0.1-2 %; BN, 0.37-2.98 %; BED, 0.62-4.45 %). The prevalence of EDs is 2.2 % (0.2-13.1 %) in Europe, 3.5 % (0.6-7.8 %) in Asia, and 4.6 % (2.0-13.5 %) in America. Comorbidity is high with psychiatric problems such as depression, anxiety, attention deficit/hyperactivity disorder, obsessive-compulsive disorder, and personality disorders.

Introducción: Introducción: los trastornos de la conducta alimentaria (TCA) son un grupo de afecciones en las cuales las creencias negativas sobre la comida, la forma del cuerpo y el peso corporal se acompañan de conductas que incluyen restricción de la ingesta, atracones, realización excesiva de ejercicio, provocación del vómito y uso de laxantes. Pueden llegar a ser graves, repercutir sobre la calidad de vida y conducir a múltiples complicaciones físicas y psiquiátricas, incluso con desenlace fatal. El propósito de este artículo es describir las características, la epidemiología y las tendencias de los TCA con información actualizada a partir de las publicaciones más recientes. Métodos: se ha realizado una búsqueda sistemática de la literatura en Medline, EMBASE, Cochrane y Web of Science. Los términos de búsqueda fueron "anorexia nervosa", "bulimia nervosa", "binge eating disorders" and "epidemiology" en título y resumen. Resultados y conclusiones: los TCA se presentan generalmente en adolescentes y adultos jóvenes. Los mejor caracterizados son la anorexia nerviosa (AN), la bulimia nerviosa (BN) y el trastorno por atracón (TA). Los estudios de prevalencia indican amplias diferencias en función del grupo de edad y el sexo, muy superior en las mujeres jóvenes (AN: 0,1-2 %; BN: 0,37-2,98 %; TA: 0,62-4,45 %). La prevalencia de los TCA es del 2,2 % (0,2-13,1 %) en Europa, del 3,5 % (0,6-7,8 %) en Asia y del 4,6 % (2,0-13,5 %) en América. La comorbilidad es elevada con problemas psiquiátricos como la depresión, la ansiedad, el déficit de atención e hiperactividad, el trastorno obsesivo-compulsivo y los trastornos de personalidad.

Design and Validation of a Scale of Knowledge of Cardiovascular Risk Factors and Lifestyle after Coronary Event.

BACKGROUND: It is important for health professionals to have tools available to assess patients' knowledge of lifestyle and cardiovascular risk factors after they have suffered a coronary event and determine whether educational interventions are effective. This study aims to design and validate a scale to evaluate this knowledge. METHODS: Four-phase instrument design: (A) Conceptual review. (B) Review by experts. (C) Pilot test-retest. (D) Psychometric validation of the final version of the questionnaire with 24 items. A panel of experts performed the content validity. The reliability of the scale was measured using Cronbach's alpha score and criterion validity was evaluated by comparing the total scores for knowledge obtained by the participants among the three education level groups. The construct and dimensional structure validity were assessed using exploratory factor analysis. RESULTS: A total of 143 people participated, 30 in the pilot study and 113 (68% male, 60.2 ± 9 years) in the psychometric validation of version 3 of the scale. A Cronbach's alpha score of 0.887 was reached for this version. The factor analysis showed that the items were distributed into five factors that explained 57% of the variance. Significant differences were observed in the level of knowledge among the patients of the three levels of education (low, moderate and high) (99.20 ± 11.93, 105.92 ± 7.85, 109.78 ± 8.76 points, p = 0.003), as there was a negative correlation between age and knowledge level (r = -0.213, p = 0.024). CONCLUSIONS: The scale presents psychometric properties that are evidence of its reliability and validity. The relationship demonstrated between the level of knowledge and age, sex and level of education shows the importance of emphasizing educational interventions for elderly people and those with a lower level of education.

Malrotación intestinal durante el embarazo: Causa de abdomen agudo oclusivo / Intestinal malrotation during pregnancy: Cause of acute occlusive abdomen

RESUMEN Fundamento: La malrotación intestinal en una embarazada es infrecuente. La incidencia de la oclusión es baja y los vólvulos son más frecuentes en el tercer trimestre de la gestación. La poca especificidad de los síntomas hace más complejo el diagnóstico temprano y el tratamiento oportuno. La asociación de estas enfermedades se considera potencialmente letal para la madre y el niño. Objetivo: Describir el caso de una paciente con oclusión intestinal por vólvulo de intestino delgado y malrotación en el curso del embarazo. Reporte de caso: Paciente de 23 años, primigesta, con 24.4 semanas de gestación, con dolores abdominales previos; se recibió en la Unidad de Cuidados Intensivos por sospecha de abdomen agudo en el embarazo. Luego de estudios imagenológicos y de laboratorio se decidió su intervención quirúrgica con el diagnóstico de obstrucción intestinal. El diagnóstico intraoperatorio fue vólvulo de intestino delgado y malrotación intestinal tipo I, se le practicó desvolvulación y operación de Ladd. La evolución fue favorable y se conservó la gestación. Conclusiones: La malrotación intestinal complicada con una oclusión en el curso del embarazo es rara y el retraso del diagnóstico puede tener implicaciones desfavorables en la evolución de la madre y su futuro hijo. Las dificultades para el diagnóstico de esta enfermedad es preocupación de la comunidad científica y debe sospecharse en gestantes que presenten síntomas y signos de oclusión intestinal y alteraciones en los estudios imagenológicos.

ABSTRACT Background: Intestinal malrotation in a pregnant woman is uncommon. The incidence of occlusion is low and volvulus are more frequent in the third trimester of pregnancy. The poor symptom specificity makes early diagnosis and treatment more complex prompt. The association of these diseases is considered potentially lethal for mother and child. Objective: To describe the case of a patient with intestinal occlusion due to intestinal volvulus thin and malrotation in the course of pregnancy. Case report: 23-year-old patient, primigravida, with 24.4 weeks of gestation, with previous abdominal pains; She was admitted to the Intensive Care Unit on suspicion of acute abdomen in pregnancy. After imaging and laboratory studies, it was decided her surgical intervention with the diagnosis of intestinal obstruction. The diagnosis intraoperative was small intestine volvulus and type I intestinal malrotation, she underwent devolvulation and operation of Ladd. The evolution was favorable and the pregnancy was preserved. Conclusions: Intestinal malrotation complicated by an occlusion in the course of Pregnancy is rare and delayed diagnosis may have unfavorable implications for the evolution of the mother and her future child. Difficulties in diagnosing this disease is a concern of the scientific community and should be suspected in pregnant women who present symptoms and signs of intestinal obstruction and alterations in imaging studies.

Independent and Combined Association of Lifestyle Behaviours and Physical Fitness with Body Weight Status in Schoolchildren.

(1) Background: Lifestyle behaviours and physical fitness play a critical role in the development of childhood obesity. It has been demonstrated in this study that self-reported physical fitness is representative of a healthy lifestyle and thus is associated with a lower incidence of overweight/obesity. The objective of this study was to analyse the independent and combined association of lifestyles (physical activity, screen time, diet and hours of sleep) and self-reported physical fitness with body weight in schoolchildren. (2) Methods: This study performed a descriptive and cross-sectional analysis. The study sample consisted of 864 schoolchildren between 8−9 years old from 26 schools of the province of Cádiz. To measure lifestyles and self-reported physical fitness, questionnaires were administered to both schoolchildren and families. To obtain the body weight status, the children were measured by body mass index (BMI). To verify the influence of lifestyles and self-reported physical fitness on the body weight status of schoolchildren, a combined score of lifestyles and self-reported physical fitness was calculated. (3) Results: Schoolchildren who followed healthier lifestyles and presented good physical fitness had a better body weight status (p < 0.001). Schoolchildren who had less healthful lifestyles and bad physical fitness had a 10.34 times higher risk of being overweight or obese (p = 0.004). (4) Conclusions: It has been shown that there is an independent and combined association between lifestyles and physical fitness on the body weight of the schoolchildren. We have suggested strategies to get children to adopt healthy lifestyles and good physical fitness to maintain a healthy body weight and prevent obesity.
