Food addiction behavior in patients with newly-diagnosed type 2 diabetes.

BACKGROUND: The concept of food addiction describes the difficulties of some individuals with regard to food consumption. OBJECTIVE: To determine the frequency of food addiction and its association with body mass index (BMI), calorie consumption and therapeutic control in patients with newly-diagnosed type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS: A total of 1,080 patients with T2DM were included. The degree of metabolic control was determined with the levels of glycated hemoglobin, low-density lipoprotein cholesterol and blood pressure. Daily caloric consumption was estimated with a semi-quantitative questionnaire of food consumption frequency. RESULTS: Nearly all patients showed overweight (40.5 %) and obesity (49.1 %). The frequency of food addiction was 54.2 % (56.9 % in women and 48.9 % in men). Food addiction was associated with BMI (OR = 1.89, p ≤ 0.05), high caloric intake (OR = 1.14, p ≤ 0.05) and glycated hemoglobin > 7 % (OR = 1.43, p ≤ 0.05). CONCLUSIONS: Food addiction is common in patients with overweight/obesity and newly-diagnosed T2DM, and is associated with higher-than-recommended caloric consumption, obesity degree and poor metabolic control.

ANTECEDENTES: El concepto de adicción a la comida describe las dificultades de algunos individuos respecto al consumo de comida. OBJETIVO: Determinar la frecuencia de la adicción a la comida y su asociación con el índice de masa corporal (IMC), consumo de calorías y control terapéutico en pacientes con diabetes mellitus tipo 2 (DMT2) de diagnóstico reciente. MATERIAL Y MÉTODOS: Se incluyeron 1080 pacientes con DMT2. Se determinó el grado de control terapéutico con niveles de hemoglobina glicada, colesterol de baja densidad y presión arterial. El consumo diario de calorías fue estimado con un cuestionario semicuantitativo de frecuencia de consumo de alimentos. RESULTADOS: Casi todos los pacientes mostraron sobrepeso (40.5 %) y obesidad (49.1 %). La frecuencia de adicción a la comida fue de 54.2 % (56.9 % en mujeres y 48.9 % en hombres). La adicción a la comida se asoció a IMC (RM = 1.89, p ≤ 0.05), alto consumo calórico (RM = 1.14, p ≤ 0.05) y hemoglobina glicada > 7 % (RM = 1.43, p ≤ 0.05). CONCLUSIONES: La adicción a la comida es frecuente en pacientes con sobrepeso/obesidad y DMT2 recientemente diagnosticada y se asocia al consumo calórico superior a lo recomendado, grado de obesidad y pobre control terapéutico.

Validation of the COVID-19 Fear Scale modified for application during the perinatal period.

PURPOSE: The COVID-19 Fear Scale (FCV-19S) allows screening in general population; however, there is no specific instrument in our population for screening in the perinatal period that considers fear related with COVID-19 and offspring well-being. We aimed to validate the FCV-19S modified for application during the perinatal period. MATERIALS AND METHODS: Analytical, cross-sectional design. After signing consent, women 18-45 years were included. Internal consistency was calculated with Cronbach's alpha, external validity using the Hospital Anxiety and Depression Scale (HADS), factorial analysis and intraclass correlation coefficient for re-test. RESULTS: The sample included 178 women, mean age 31.04 ± 5.9. We obtained internal consistency with Cronbach's alpha = 0.873 (95%CI, 0.842-0.899). Spearman's Rho coefficient was 0.207 (p= .013). All the elements were statistically significant for the polychoric correlation (p<.001). Reliability test-retest with intraclass correlation was 0.873. CONCLUSIONS: The version of FCV-19S modified with eight items is a valid measurement instrument for application during the perinatal period, showing adequate internal consistency and external validity with HADS as measure of concurrence to identify anxiety related with COVID-19 during the perinatal period.

Are Women Ready to Prevent Osteoporosis? Change Stages for Preventive Behaviors.

OBJECTIVE: Evaluate the prevention behaviors for osteoporosis (OP) in women (physical activity and calcium intake) and their readiness to perform these behaviors. METHOD: Women aged ≥30 years in four large cities of Mexico were interviewed. The geographical areas were selected randomly and stratified according to socioeconomic status and age. A questionnaire designed to assess OP-related prevention behaviors, as well as attitudes and stages of change of the transtheoretical model toward these behaviors, was used. RESULTS: Eight hundred and six women were interviewed: 4.2% reported diagnosis of osteopenia, 5% of OP, 2.3% had suffered a fracture, and 11.9% had a family history of OP. A large proportion of participants did not do physical activity (56.2%) and did not have the recommended intake of calcium (61.3%). More than 80% of these participants were in lower stages of change (precontemplation and contemplation) for performing physical activity and 86.4% for calcium intake, which means a lack of readiness to change their behaviors. The absence of readiness to change preventive behaviors was related to negative attitudes toward both behaviors (OR = 1.81, 95% CI [1.04, 3.14] physical activity; OR = 3.09, 95% CI [1.81, 5.29] calcium intake). Both of these behaviors were associated with known risk factors for OP. CONCLUSION: Very high percentage of women are not ready to perform the behaviors necessary to maintain bone health. This phenomenon was not as a result of clinical risk factors for OP but because of the negative attitudes and beliefs of women related to physical activity and calcium intake.

Markers of disease severity and positive family history are associated to significant risk perception in rheumatoid arthritis, while compliance with therapy is not: a cross-sectional study in 415 Mexican outpatients.

BACKGROUND: Assessing risk perception (RP) helps explain how rheumatoid arthritis (RA) patients integrate their ideas concerning the disease and how this understanding affects their self-care management. Compliance with treatment impacts disease-related outcomes and could be associated with RP to variable degrees and at different levels. The primary objective was to determine a potential association between RP and compliance with therapy in RA outpatients and to identify additional factors. The secondary objective was to identify factors associated with judgment bias such as unrealistic RP. PATIENTS AND METHODS: Between January 2018 and June 2019, 450 consecutive outpatients who received RA-related treatment were invited to a face-to-face interview to obtain socio-demographic data, RA-related information, comorbidities, and the following outcomes: adherence, persistence, and concordance with medications assessed with a questionnaire locally designed; RP with the RP questionnaire (RPQ); disease activity with the Routine Assessment of Patient Index Data-3 (RAPID-3); disability with the Health Assessment Questionnaire Disability Index (HAQ-DI); quality of life with Medical Outcomes Study Short Form-36 (SF-36) instrument; pain and overall disease with the respective visual analogue scale (VAS); and health literacy assessed with 3 questions. Significant RP was defined according to a cut-off based on the 75th percentile value of the sample in which the RPQ was validated. Unrealistic RP was defined based on the coincidence of the presence/absence of significant RP and less/more than 7 unfavorable medical criteria. Multiple logistic regression analysis was used. Patients provided written informed consent and the study received Internal Review Board approval. RESULTS: There were 415 patients included, primarily middle-aged women with long-standing disease and moderate disease activity. Almost half of the patients were receiving corticosteroids and 15.9% intensive RA-related treatment. There were 44.1% of the patients concordant with treatment and 22.6% had significant RP. The patients' treatment behavior was not retained in the regression analysis; meanwhile, rheumatoid nodes, surgical joint replacement, family history of RA, and higher RAPID-3 score were associated with significant RP. There were 56 patients with unrealistic RP; significant RP and more unfavorable medical criteria were associated with unrealistic RP. CONCLUSIONS: Compliance with therapy was not associated with significant RP in RA outpatients.

Validation of a risk perception questionnaire developed for patients with rheumatoid arthritis.

BACKGROUND: Risk perception is a multidimensional phenomenon that describes the individual's judgment of the likelihood of experiencing something unpleasant. Risk perception helps to understand how rheumatoid arthritis patients perceive disease-related-risks. We developed and validated a risk perception questionnaire for Spanish speaking rheumatoid arthritis patients. METHODS: The questionnaire development and validation was performed in 3 steps, using respective convenience samples. Step-1 included the conceptual model construction, 20 patient's interviews to identify components from the conceptual model-dimensions and 11 healthcare provider´s consultations who identified RA related manifestations/complications (network and frequencies analysis). Step-2 consisted of item generation and reduction and questionnaire feasibility (n = 100). Step-3 consisted of the questionnaire psychometric validation (n = 270), which included content, face, construct (exploratory factor analysis) and criterion validity (logistic regression analysis) and consistency and stability (Cronbach's α and test-retest). RESULTS: Samples were representative of typical RA outpatients. Initial conceptual model included 7 dimensions, 3 for probability and 1 each, for responsibility, prevention, control and for severity (Step-1). The final version was considered feasible by the patients and included 27 items (Step-2). A five-factor model was most appropriated and resulted in 68.8% of the variance explained: Cronbach's α = 0.90, intraclass-correlation-coefficient = 0.93 (95% CI = 0.90-0.95). A positive relation between number of external criteria from the charts and risk perception was found; all items had ≥80% agreement from experts; patients agreed about item´s semantic clarity (89%) and format adequacy (97%), (Step-3). CONCLUSIONS: The risk perception questionnaire was valid and reliable to evaluate risk perception construct in RA outpatients; it can be incorporated to routine care and clinical research, and guide interventions to improve patient's health behaviors.

Inercia clínica en el tratamiento con insulina en el primer nivel de atención.

INTRODUCTION: Refusal of physicians to prescribe insulin to their patients has been scarcely evaluated; the delay in treatment intensification hinders adequate and quality care. OBJECTIVE: To identify the perception of primary care physicians about barriers to initiate insulin treatment in patients with diabetes. METHOD: Using the Smith Index and multivariate analysis, the relevance and grouping of concepts related to barriers to insulin prescription were assessed in 81 family doctors. RESULTS: Only 35.8% of physicians showed confidence for prescribing insulin; almost half of them rated treatment intensification between moderately and little important (39.5% and 6.2%). Barriers were related to the physician (39.5%), the patient (37%), insulin treatment (11.1%) and the institution (6.2%); 6.2 % of physicians did not perceive any barrier. The barriers were grouped in 5 factors that explained 62.48% of the variance: patient cultural level, lack of medical skills, fear of adverse events, insecurity and lack of training. CONCLUSION: Clinical inertia was not the result of a complex medical condition or patient comorbidities, but of doctor's perception and confidence in his/her clinical and communication skills.

INTRODUCCIÓN: Poco se ha evaluado el rechazo de los médicos a prescribir insulina a sus pacientes; el retraso en intensificar el tratamiento impide una atención adecuada y de calidad. OBJETIVO: Identificar la percepción de los médicos acerca de las barreras para iniciar la insulina en los pacientes con diabetes. MÉTODO: Por Índice Smith y análisis multivariado, en 81 médicos familiares se evaluó la relevancia y agrupación de los conceptos relacionados con las barreras para la prescripción de insulina. RESULTADOS: 35.8 % de los médicos mostró confianza en prescribir insulina; casi la mitad calificó la intensificación del tratamiento entre moderadamente y poco importante (39.5 y 6.2 %). Las barreras se relacionaron con el médico (39.5 %), el paciente (37 %), el tratamiento con insulina (11.1 %) y la institución (6.2 %); 6.2 % de los médicos no percibió ninguna barrera. Las barreras se agruparon en cinco factores, que explicaron 62.48 % de la varianza: cultura de los pacientes, falta de habilidades, miedo a los eventos adversos, inseguridad y falta de capacitación. CONCLUSIÓN: La inercia clínica no resultó de una condición clínica compleja o comorbilidades del paciente, sino de la percepción del médico y de su confianza en sus habilidades clínicas y comunicativas.

Prevention of low bone mass to achieve high bone density in Mexico: position of the Mexican Association for Bone and Mineral Metabolism.

In Mexico, osteoporosis is a public health problem. In this document, the Mexican Association for Bone and Mineral Metabolism defines its position on calcium, vitamin D supplement use, and physical activity as an effective, safe, and cost-effective initiatives to prevent low bone mass. INTRODUCTION: In Mexico, osteoporosis is a public health problem that is expected to increase in the decades ahead. Generally, modifiable risk factors for bone health are related with lifestyles, especially nutrition and physical activity. METHODS: In this position paper, the Mexican Association for Bone and Mineral Metabolism (AMMOM, by its acronym in Spanish), which is a multidisciplinary group of researchers, dietitians, epidemiologists, nurses, and physicians who study bone and related tissues and communicate the best strategies for diagnosis, treatment, and prevention of bone problems, aims to analyze the association between nutrition and bone health, risk behaviors for low bone mass, and the economic impact that prevention of low bone mass represents for the health care system. RESULTS: Addressing therapeutic management with pharmacological and non-pharmacological approaches, we emphasize the important role the patient plays in the doctor-patient relationship, both in the consulting room and in daily life. Furthermore, the AMMOM defines its position on calcium and vitamin D supplement use as an effective, safe, and cost-effective initiative to prevent low bone mass. CONCLUSIONS: In summary, most research and clinical practice related to osteoporosis have focused on diagnosis and treatment, but general measures for primary prevention based on addressing modifiable risk factors as a public health priority to delay the onset of loss of bone mass have not been considered by Mexican authorities. Consequently, the AMMOM task force also seeks to provide information on concrete actions to prevent low bone mass.

Prevalence of Cognitive Impairment in Recently Diagnosed Type 2 Diabetes Patients: Are Chronic Inflammatory Diseases Responsible for Cognitive Decline?

OBJECTIVE: To estimate the prevalence of cognitive impairment (CI) among patients recently diagnosed with type 2 diabetes (RDD) and to identify any relationships between CI and RDD comorbidities. METHODS: One thousand seven hundred twelve patients with RDD participated in a cross-sectional study. The patients' sociodemographic and clinical data were registered. RESULTS: The sample population had an average age of 51 ± 11 years, and 63.26% of the patients were female. CI was diagnosed in 38 patients (2.2%) and was more common among both females (2.8% vs. 1.3%, p = 0.063) and the elderly (0% at an age ≤ 30 years vs. 10.4% at an age > 70 years, p = 0.0001). Rheumatoid arthritis (present in 15.8% vs. absent in 2.1%) and asthma (13% vs. 2.1%) correlated significantly with CI based on the results of our logistic regression analysis. CONCLUSION: Age, female gender, rheumatoid arthritis and asthma are risk factors for CI in the setting of RDD.

Risk perception and knowledge about osteoporosis: well informed but not aware? A cross-sectional study.

Identify the level of knowledge and risk perception of developing osteoporosis (OP) and its association with socio-demographic variables and risk factors. Individuals older than 18 years living in Mexico City were surveyed. The sample, which was designed to be representative of this population, was randomly selected and stratified by socioeconomic level, age, and sex. The Multiple Osteoporosis Prevention Survey, designed to assess OP-related knowledge, risk perception, was used. Four hundred and fifty-five individuals, homogeneously distributed according to defined strata, were surveyed. Almost 29 % (28.9 %) of subjects consumed tobacco, and 13.4 % had a family history of OP. Most subjects reported a lower-than-recommended calcium daily intake. Fifty-three and a half percent identified most risk factors adequately, and almost all (97.9 %) had received some sort of information about OP. Sixty-six and a half percent of subjects perceived OP as a serious disease; 51.5 % considered themselves to be personally responsible for acquiring it; 50.2 % were concerned about suffering from it; and 47.1 % considered it likely they would develop it. The most important variables associated with the perception of risk were age (<45 years), gender (female), and family history of OP. Subjects considered it more likely, more serious, and felt more worried and personally responsible about developing a heart condition or cancer than OP; they felt less concerned, less personally responsible, and less likely to contract AIDS or develop Alzheimer's. Individuals know a lot about OP, but they engage in risky behaviors and lack perception of their risk in developing it. Interventions should aim at raising awareness about personal responsibility and about the likelihood of developing this condition.

The predictors of glucose screening: the contribution of risk perception.

BACKGROUND: The prevention of type 2 diabetes is a challenge for health institutions. Periodic blood glucose screening in subjects at risk for developing diabetes may be necessary to implement preventive measures in patients prior to the manifestation of the disease and to efficiently diagnose diabetes. Not only medical aspects, but also psychological and social factors, such as the perception of risk (the individuals' judgment of the likelihood of experiencing an adverse event) influence healthy or preventive behaviors. It is still unknown if risk perception can have an effect on health behaviors aimed at reducing the risk of diabetes (glucose screening). The objective of study was to identify factors that influence glucose screening frequency. METHODS: Eight hundred randomized interviews, which were stratified by socioeconomic level, were performed in Mexico City. We evaluated the perception of risk of developing diabetes, family history, health status and socioeconomic variables and their association with glucose screening frequency. RESULTS: Of the study participants, 55.6% had not had their glucose levels measured in the last year, whereas 32.8% of the subjects reported having monitored their glucose levels one to three times per year and 11.5% had their levels monitored four or more times per year. Risk perception was significantly associated with the frequency of blood glucose screening. Having a first-degree relative with diabetes, being older than 45 years and belonging to a middle socioeconomic level increased the probability of subjects seeing a doctor for glucose screening. CONCLUSIONS: Glucose screening is a complex behavior that involves the subjects' perception of threat, defined as feeling vulnerable to the development of diabetes, which is determined by the subject's environment and his previous experience with diabetes.

Ethical behaviours in clinical practice among Mexican health care workers.

The objective of this study was to describe the cultural domain of ethical behaviours in clinical practice as defined by health care providers in Mexico. Structured interviews were carried out with 500 health professionals employed at the Mexican Institute of Social Security in Mexico City. The Smith Salience Index was used to evaluate the relevance of concepts gathered from the free listings of the interviewees. Cluster analysis and factor analysis facilitated construction of the conceptual categories, which the authors refer to as ;dimensions of ethical practice'. Six dimensions emerged from the analysis to define the qualities that comprise ethical clinical practice for Mexican health care providers: overall quality of clinical performance; working conditions that favour quality of care; use of ethical considerations as prerequisites for any health care intervention; values favouring teamwork in the health professional-patient relationship; patient satisfaction scores; and communication between health care providers and patients. The findings suggest that improved working conditions and management practices that promote the values identified by the study's participants would help to improve quality of care.

[Illness behavior in chronic pain]. / Conducta del enfermo ante el dolor crónico.

OBJECTIVE: To describe the illness behaviour in patients with chronic pain. MATERIAL AND METHODS: We conducted semi-structured interviews to 53 patients during 2000, in a tertiary care center. We explored their initial interpretations, responses and subsequent practices to chronic pain, until they received a diagnosis that satisfied them. RESULTS: Illness behaviour was determined by pain intensity and disability; beliefs regarding pain causes, trust in social networks, and quality and satisfaction with the health care systems. In terms of the decision to seek care, the first option was to go to the popular sector, followed by consulting a general physician, and as last resort, to go to a tertiary care center ("with a specialist"). CONCLUSIONS: Illness behaviour should be conceptualized as a process, which combines the use of different health care sectors by the same subjects, as a result of care provided sequentially by each previous sector.

Conducta del enfermo ante el dolor crónico / Illness behavior in chronic pain

OBJETIVO: Describir la "conducta de enfermedad" en pacientes con dolor crónico. MATERIAL Y MÉTODOS: Durante el año 2000 se realizaron entrevistas semiestructuradas a 53 pacientes en una institución del tercer nivel de atención. Allí se exploró su interpretación y respuesta inicial al dolor crónico y prácticas subsecuentes hasta sentirse satisfechos con el diagnóstico recibido. RESULTADOS: La conducta de enfermedad estuvo determinada por la intensidad, discapacidad y creencias de las causas del dolor, recomendaciones de las redes de apoyo, la calidad y satisfacción con los sistemas de atención. En términos de la toma de decisión, la primera opción fue acudir al sector popular, y consultar al médico general, para finalmente acudir a un tercer nivel de atención ("con el especialista"). CONCLUSIONES: La conducta de enfermedad es un proceso en el que se utilizan los diferentes sectores de la atención por parte de los mismos sujetos y que es determinado por el resultado de la atención brindada.

Incidence rates and life-time risk of hip fractures in Mexicans over 50 years of age: a population-based study.

The vast majority of hip fractures in the 21st century will occur in the developing countries. The rates and life-time hip fracture risk are not known for Mexico, and for this reason, we studied the incidence of hip fractures, and the remaining life-time probability of having a hip fracture at the age of 50 years in Mexican men and women. All hip fracture cases registered during the year 2000 were collected at all the main tertiary-care hospitals in the two major health systems in México City, Instituto Mexicano del Seguro Social (IMSS) and Ministry of Health (SS), and the diagnosis was validated by chart review in all cases. The annual rates of hip fracture were 169 in women and 98 in men per 100,000 person-years. The life-time probability of having a hip fracture at 50 years of age was 8.5% in Mexican women and 3.8% in Mexican men. We conclude that hip fractures are an important health problem in Mexico and that Mexican health authorities should consider public health programs to prevent hip fractures.

Patient ratings of care at a rheumatology out-patient unit.

BACKGROUND: Our objective was to determine patient satisfaction with services rendered by health care personnel at the rheumatology out-patient consultation. METHODS: We carried out a cross-sectional survey at a tertiary-level care hospital in Mexico City. A questionnaire on satisfaction with quality of medical care was applied to 347 adult patients who attended the out-patient rheumatology clinic at least twice and who agreed to participate. Questions in the instrument covered three aspects of quality of care, including structure, process, and results. RESULTS: In overall assessment, 83.5% of patients reported satisfaction with care. Structure received worst score and process, the best. Outcomes (e.g., disease improvement) received intermediate scores. Correlations within these areas were strong but correlation with overall satisfaction was not high. The majority of patients stated that physician competence was the most valuable aspect of the visit; the least valuable was waiting time. CONCLUSIONS: Specific strategies need to be implemented to improve certain areas. Overall satisfaction as a measurement renders no specific and useful information due to complexity with regard to different dimensions of satisfaction.

Learning from pain scales: patient perspective.

OBJECTIVE: Rheumatologists often deal with patients' pain, as commonly measured by clinical scales. However, no published study in the last 25 years has explored patient preferences for the 2 most frequently used clinical scales the verbal rating scale (VRS) and the visual analog scale (VAS). We (1) evaluated patient preferences for the 10 cm horizontal VAS versus the 5 point VRS and identified associated reasons for their preferences; and (2) validated the test-retest reliability and construct validity of these scales. METHODS: Patients with painful rheumatological conditions rated the VAS and the VRS to assess pain intensity and stated which scale they preferred and why. Exploration of tender points and dolorimetry was performed in all cases. RESULTS: Of 113 patients in the sample, 93% were women, 85% of whom had rheumatoid arthritis. In this sample, 52.8% preferred the VRS, 28.3% the VAS, and 18.9% expressed no preference. Patients who preferred the VRS said it was easier than the VAS to understand and rate. They also reported being more comfortable using words than numbers. Patients who preferred the VAS said that numbers classified pain better and that this allowed them to be objective and precise. Patients with 0-6 years of schooling preferred the VRS, while those with > 6 years preferred the VAS. There was a significant association between the number of tender points and pain intensity with both scales, as well as between threshold and tolerance with the VAS. High correlations were found between the VAS and the VRS (r = 0.79) and between tolerance and threshold (r = 0.96). Test-retest showed a high correlation for both scales: VAS = 0.97 and VRS = 0.89. CONCLUSION: Both scales are valid measures of pain intensity. The choice should depend on the setting, the clinician's goal, and the patient's level of education. Patient preference is central to better physician-patient communication.
