RESUMO

BACKGROUND: The predictive ability of the early determination of sex steroids and the total testosterone:estradiol ratio for the risk of severe coronavirus disease 2019 or the potential existence of a biological gradient in this relationship has not been evaluated. OBJECTIVES: To assess the relationship of sex steroid levels and the total testosterone:estradiol ratio with the risk of severe acute respiratory syndrome coronavirus 2 infection in men, defined as the need for intensive care unit admission or death, and the predictive ability of each biomarker. MATERIALS AND METHODS: This was a prospective observational study. We included all consecutive adult men with severe acute respiratory syndrome coronavirus 2 infections in a single center admitted to a general hospital ward or to the intensive care unit. Sex steroids were evaluated at the centralized laboratory of our hospital. RESULTS: We recruited 98 patients, 54 (55.1%) of whom developed severe coronavirus disease in 2019. Compared to patients with nonsevere coronavirus disease 2019, patients with severe coronavirus disease 2019 had significantly lower serum levels of total testosterone (111 ± 89 vs. 191 ± 143 ng/dL; p < 0.001), dehydroepiandrosterone (1.69 ± 1.26 vs. 2.96 ± 2.64 ng/mL; p < 0.001), and dehydroepiandrosterone sulfate (91.72 ± 76.20 vs. 134.28 ± 98.261 µg/dL; p = 0.009), significantly higher levels of estradiol (64.61 ± 59.35 vs. 33.78 ± 13.78 pg/mL; p = 0.001), and significantly lower total testosterone:estradiol ratio (0.28 ± 0.31 vs. 0.70 ± 0.75; p < 0.001). The lower the serum level of androgen and the lower the total testosterone:estradiol ratio values, the higher the likelihood of developing severe coronavirus disease 2019, with the linear trend in the adjusted analyses being statistically significant for all parameters except for androstenedione (p = 0.064). In the receiver operating characteristic analysis, better predictive performance was shown by the total testosterone:estradiol ratio, with an area under the curve of 0.77 (95% confidence interval 0.68-0.87; p < 0.001). DISCUSSION AND CONCLUSION: Our results suggest that men with severe acute respiratory syndrome coronavirus 2 infection, decreased androgen levels and increased estradiol levels have a higher likelihood of developing an unfavorable outcome. The total testosterone:estradiol ratio showed the best predictive ability.

RESUMO

OBJECTIVES: To analyze the effectiveness of a multicomponent treatment for smoking cessation carried out in primary care and to evaluate the evolution of the consumption of tobacco that the people who participated had, more than 5 years after the end of the treatment. DESIGN: Longitudinal study of 307 participants in a multicomponent program in group format of tobacco cessation. EMPLACEMENT: Santander (Spain) Primary Care Health Center. PARTICIPANTS: Smokers from the basic health zone who wanted to quit smoking between 2006 and 2012 and requested help. INTERVENTIONS: Multicomponent treatment of 5face-to-face sessions and follow-up for up to 12 months. PRIMARY MEASUREMENTS: The activity was evaluated in 263 participants more than 5years after the end of treatment. The results of continuous and punctual withdrawal were obtained by self-declaration and the data recorded in the medical record. The punctual was also validated with co-oximetry. RESULTS: After a year 42.7% of participants declared continuous abstinence. From 5 to 12 years later, the continuous declared abstinence further than 12 months was 40.7%. They did not smoke again since the end of the treatment 66 people; 68.0% of those who relapsed made new attempts and 45.5% of them requested help to quit smoking. CONCLUSIONS: The proposed multi-component treatment is effective. Abstinence at 12 months predicts long-term maintenance and participating in disabling groups favors further attempts in case of relapse and the request for help to quit smoking.

RESUMO

BACKGROUND: Methemoglobinemia (MetHb) is a rare and potentially severe dyshemoglobinemia that can be induced by exposure to oxidizing agents, decreasing the functional capacity of the hemoglobin molecule to transport and release oxygen into the tissues. MetHb can originate from gases with oxidizing capacity generated by internal combustion engines, although since the universalization of catalyst converters in automobiles, a tiny proportion of MetHb poisoning is due to exposure to engine gases and fumes. Within this group, only two cases due to suicidal motivations have been reported in the last 30 years. CASE PRESENTATION: Here, we expose the case of a patient with MetHb levels of 25.2% (normal 0-1.5%) who with suicidal motivations had attached and locked a hose to the exhaust pipe of her vehicle with electrical tape, becoming exposed to a sustained concentration of the vehicle's exhaust. Upon her arrival at the emergency department, the presence of generalized greyish cyanosis with alterations of the sensorium, dissociation between saturation measured by arterial blood gas analysis and pulse oximetry (98% vs. 85%), no response to high-flow oxygen therapy, and an excellent response to intravenous methylene blue treatment were highlighted. CONCLUSIONS: This report illustrates an original case of acute toxic acquired MetHb due to inhalation of oxidizing substances originating from the bad ignition of an internal combustion engine. When evaluating a patient with suspected gas intoxication, we usually consider poisoning by the most common toxins, such as carbon monoxide or cyanide. In this context, we propose an algorithm to assist in the suspicion of this entity in patients with cyanosis in the emergency department. MetHb poisoning should be suspected, and urgent co-oximetry should be requested when there is no congruence between cyanosis intensity and oxygen saturation measured by pulse oximetry, if there is discordance between the results of oxygen saturation measured by arterial blood gas and pulse oximeter, and if there is no response to oxygen treatment. This algorithm could be useful to not delay diagnosis, improve prognosis, and limit potential sequelae.

RESUMO

Background: The aim of this study was to relate adherence to the Mediterranean diet (MedDiet) to the prevalence of metabolic syndrome (MetS) in an elderly population from the north of Spain. Methods: We carried out an observational, descriptive, cross-sectional, and correlational study involving 556 non-institutionalised individuals aged 65 to 79 years. The MEDAS-14 questionnaire score was used to define the degree of adherence to the Mediterranean diet. The diagnosis of MetS was conducted using the International Diabetes Federation (IDF) criteria. Results: In 264 subjects with an average age of 71.9 (SD: ±4.2), 39% of whom were men, 36.4% had good adherence (score ≥ 9 in MEDAS-14), with no differences by gender or age. The prevalence of MetS was 40.2%, with 47.6% in men and 35.4% in women (p < 0.05). The prevalence of MetS was 2.4 times more frequent among individuals who consumed less than two servings (200 g) of vegetables daily compared with those who consumed two or more servings of vegetables daily (OR: 2.368, 95%CI: 1.141−4.916, p = 0.021). Low adherence to the MedDiet (MEDAS-14 score ≤ 8) was associated with an 82% higher prevalence of MetS (OR: 1.817, 95%CI: 1.072−3.081, p = 0.027). Conclusion: An inverse relationship was established between adherence to the MedDiet and the prevalence of MetS.

RESUMO

The purpose of the study was to analyze the relationship between the high-sensitivity troponin T levels in patients with confirmed influenza virus infection and its severity determined by mortality during the care process. In addition, a high-sensitivity troponin T cut-off value was sought to allow us to a safe discharge from the emergency department. An analytical retrospective observational study was designed in which high-sensitivity troponin T is determined as an exposure factor, patients are followed until the resolution of the clinical picture, and the frequency of mortality is analyzed. We included patients ≥ 16 years old with confirmed influenza virus infection and determination of high-sensitivity troponin T. One hundred twenty-eight patients were included (96.9% survivors, 3.1% deceased). Mean and median blood levels of high-sensitivity troponin T of survivors were 26.2 ± 58.3 ng/L and 14.5 ng/L (IQR 16 ng/L), respectively, and were statistically different when compared with those of the deceased patients, 120.5 ± 170.1 ng/L and 40.5 ng/L (IQR 266.5 ng/L), respectively, p = 0.012. The Youden index using mortality as the reference method was 0.76, and the cut-off value associated with this index was 24 ng/L (sensitivity 100%, specificity 76%, NPV 100%, PPV 4%) with AUC of 88,8% (95% CI: 79.8−92.2%), p < 0.001. We conclude that high-sensitivity troponin T levels in confirmed virus influenza infection are a good predictor of mortality in our population, and this predictor is useful for safely discharging patients from the emergency department.

RESUMO

BACKGROUND: To evaluate a wide range of optical coherence tomography (OCT) parameters for possible application as a screening tool for cognitively healthy individuals at risk of Alzheimer's disease (AD), assessing the potential relationship with established cerebrospinal fluid (CSF) core AD biomarkers and magnetic resonance imaging (MRI). METHODS: We studied 99 participants from the Valdecilla Study for Memory and Brain Aging. This is a prospective cohort for multimodal biomarker discovery and validation that includes participants older than 55 years without dementia. Participants received a comprehensive neuropsychological battery and underwent structural 3-T brain MRI, lumbar puncture for CSF biomarkers (phosphorylated-181-Tau (pTau), total Tau (tTau), beta-amyloid 1-42 (Aß 1-42), and beta-amyloid 1-40 (Aß 1-40)). All individuals underwent OCT to measure the retinal ganglion cell layer (GCL), the retinal nerve fiber layer (RFNL), the Bruch's membrane opening-minimum rim width (BMO-MRW), and choroidal thickness (CT). In the first stage, we performed a univariate analysis, using Student's t-test. In the second stage, we performed a multivariate analysis including only those OCT parameters that discriminated at a nominal level, between positive/negative biomarkers in stage 1. RESULTS: We found significant differences between the OCT measurements of pTau- and tTau-positive individuals compared with those who were negative for these markers, most notably that the GCL and the RNFL were thinner in the former. In stage 2, our dependent variables were the quantitative values of CSF markers and the hippocampal volume. The Aß 1-42/40 ratio did not show a significant correlation with OCT measurements while the associations between pTau and tTau with GCL were statistically significant, especially in the temporal region of the macula. Besides, the multivariate analysis showed a significant correlation between hippocampal volume with GCL and RNFL. However, after false discovery rate correction, only the associations with hippocampal volume remained significant. CONCLUSIONS: We found a significant correlation between Tau (pTau) and neurodegeneration biomarkers (tTau and hippocampus volume) with GCL degeneration and, to a lesser degree, with damage in RFNL. OCT analysis constitutes a non-invasive and unexpensive biomarker that allows the detection of neurodegeneration in cognitively asymptomatic individuals.

RESUMO

OBJECTIVES: Several studies have reported the role of immune-related adverse events as a predictor of clinical benefit, but few have properly described these findings in advanced or metastatic non-small cell lung cancer treated with pembrolizumab. This study aimed to evaluate the association between immune-related adverse events development and clinical outcomes in the aforementioned group of patients. METHODS: We conducted a retrospective study in patients with advanced or metastatic non-small cell lung cancer treated with pembrolizumab. Overall response rate, progression-free survival and overall survival were evaluated according to the appearance, subtype and number of immune-related adverse events developed. We report the results of the immune-related adverse events analysis and the potential correlation between immune-related adverse events and clinical outcomes. Univariate and multivariate analyses were performed to evaluate this relationship. RESULTS: A total of 94 patients were analysed; 60 of them developed immune-related adverse events. Patients with immune-related adverse events had a significantly higher overall response rate compared with the non-immune-related adverse events group (34% vs 8.5%, χ2=0.005). Median progression-free survival was statistically significant in favour of patients with at least one immune-related adverse event (p=0.015). Median overall survival was not reached in patients with ≥1 immune-related adverse events, compared with 8 months (95% CI 0.6 to 15.4 months) in those without immune-related adverse events. Patients who developed ≥2 immune-related adverse events had longer median progression-free survival (11 vs 4 months, not statistically significant) and overall survival (not reached vs 11, p=0.022) compared with those with ≤1 immune-related adverse events. CONCLUSIONS: Obtained data showed that patients with immune-related adverse events occurrence had significantly better overall response rate and longer progression-free survival and overall survival. This study highlights the role of immune-related adverse events as a predictor of survival in a real-life setting.

RESUMO

BACKGROUND: The aim of this study was to relate the adherence to nut consumption (30 g) three or more days per week to the prevalence of abdominal obesity and metabolic syndrome (MetS) in an elderly population from the north of Spain. METHODS: The study consists of an observational, descriptive, cross-sectional, and correlational study conducted in 556 non-institutionalised individuals between 65 and 79 years of age. To define the consumption recommendation of nuts the indication of the questionnaire MEDAS-14 was followed. The diagnosis of MetS was conducted using the International Diabetes Federation (IDF) criteria. RESULTS: In 264 subjects aged 71.9 (SD: ±4.2) years old, 39% of whom were men, the adherence to nut consumption recommendations was 40.2%. Of these individuals, 79.5% had abdominal obesity. The prevalence of MetS was 40.2%, being 47.6% in men and 35.4% in women (p < 0.05). A nut consumption lower than recommended was associated with a 19% higher prevalence of abdominal obesity (Prevalence Ratio: 1.19; 95% CI: 1.03-1.37; p < 0.05) and a 61% higher prevalence of MetS (Prevalence Ratio: 1.61; 95% CI: 1.16-2.25; p = 0.005) compared to a consumption of ≥3 servings per week. CONCLUSION: An inverse relationship was established between nut consumption and the prevalence of abdominal obesity and metabolic syndrome.

RESUMO

OBJECTIVE: To analyse a cohort of pregnant patients with systemic lupus erythematosus and compare the outcomes of both the disease and pregnancy with the results of previous studies conducted in the same geographical area. PATIENTS AND METHODS: Retrospective cohort study of 37 women with systemic lupus erythematosus (64 pregnancies) followed in a multidisciplinary unit. Comparative study with similar Spanish studies identified after literature search. RESULTS: Our cohort was characterized by an older age and by the presence of non-Caucasian patients. Although we found no clinical differences, from the serological point of view our cohort presented a higher frequency of antiphospholipid antibodies. Patients included in this study were treated more frequently with antimalarials and low-dose aspirin. Systemic lupus erythematosus flare frequency was very similar between the different studies, and we did not identify clear predictors for them. Although the rate of live births was similar among studies, the obstetric outcome of our series was better with a very low rate of preeclampsia, preterm birth and low birth weight newborn. The only predictor of adverse obstetric event was age. CONCLUSIONS: Although changes in the therapeutic attitude and planning of pregnancy in recent years have not had a direct impact on the rate of systemic lupus erythematosus flares during pregnancy, they have meant an improvement in the obstetric results. The introduction of new variables independent of the disease such as age at conception, socio-cultural origin, or the availability of multidisciplinary units should be considered in the results of future studies.

RESUMO

BACKGROUND: Cardiac surgery with extracorporeal circulation (ECC) requires the administration of anticoagulant drugs to maintain ACT ranges 400-600 seconds, which requires exhaustive coagulation monitoring for which various point-of-care devices are available. However, there is variability between them, so we aimed to compare the values in ACT measurement. METHODS: Simultaneous ACT measurements were performed with the Hemochron Response®, Hemostasis Management System Plus® (HMS Plus®) and Hemochron Signature® systems. RESULTS: A total of 255 simultaneous measurements were taken, the mean and standard deviation (SD) of each device were: Hemochron Signature® 361.1 seconds (SD: 156.9), HMS Plus® 412.8 seconds (SD: 180.9) and Hemochron Response® 422.8 seconds (SD: 187.9), being these differences statistically significant (Fridman's test p < 0.01). For comparisons the Bland-Altman method was used, resulting the Hemochron Response® has 61.7 seconds higher mean values than the Hemochron Signature®, the Hemochron Response® 10 seconds higher than the HMS Plus® and the HMS Plus® 51.7 seconds higher than the Hemochron Signature®. CONCLUSION: The differences found in comparisons are considered to be clinically relevant, which is why it is considered important to make the variability of the different monitoring systems known and to take them into account for optimal control of this parameter and its clinical repercussions.

RESUMO

BACKGROUND: The role of vitamin D status in COVID-19 patients is a matter of debate. OBJECTIVES: To assess serum 25-hydroxyvitamin D (25OHD) levels in hospitalized patients with COVID-19 and to analyze the possible influence of vitamin D status on disease severity. METHODS: Retrospective case-control study of 216 COVID-19 patients and 197 population-based controls. Serum 25OHD levels were measured in both groups. The association of serum 25OHD levels with COVID-19 severity (admission to the intensive care unit, requirements for mechanical ventilation, or mortality) was also evaluated. RESULTS: Of the 216 patients, 19 were on vitamin D supplements and were analyzed separately. In COVID-19 patients, mean ±â€…standard deviation 25OHD levels were 13.8 ±â€…7.2 ng/mL, compared with 20.9 ±â€…7.4 ng/mL in controls (P < .0001). 25OHD values were lower in men than in women. Vitamin D deficiency was found in 82.2% of COVID-19 cases and 47.2% of population-based controls (P < .0001). 25OHD inversely correlates with serum ferritin (P = .013) and D-dimer levels (P = .027). Vitamin D-deficient COVID-19 patients had a greater prevalence of hypertension and cardiovascular diseases, raised serum ferritin and troponin levels, as well as a longer length of hospital stay than those with serum 25OHD levels ≥20 ng/mL. No causal relationship was found between vitamin D deficiency and COVID-19 severity as a combined endpoint or as its separate components. CONCLUSIONS: 25OHD levels are lower in hospitalized COVID-19 patients than in population-based controls and these patients had a higher prevalence of deficiency. We did not find any relationship between vitamin D concentrations or vitamin deficiency and the severity of the disease.

RESUMO

AIM: Results from meta-analyses point to an association between vitamin D deficiency and the onset of diabetic retinopathy (DR). The objectives of the present study were to evaluate the association of vitamin D for the development of DR and to determine the levels of vitamin D associated with a greater risk of DR. METHODS: Between November 2013 and February 2015, we performed a case-control study based on a sample of patients with diabetes in Spain. The study population comprised all patients who had at least one evaluable electroretinogram and recorded levels of 25(OH)D. We collected a series of analytical data: 25(OH)D, 1,25(OH)2D, iPTH, calcium, albumin, and HbA1c. Glycemic control was evaluated on the basis of the mean HbA1c values for the period 2009-2014. A logistic regression analysis was performed to identify the variables associated with DR. RESULTS: The final study sample comprised 385 patients, of which 30 (7.8%) had DR. Significant differences were found between patients with and without DR for age (69.54 vs. 73.43), HbA1c (6.68% vs. 7.29%), years since diagnosis of diabetes (10.9 vs. 14.17), level of 25(OH)D (20.80 vs. 15.50 ng/mL), level of 1,25(OH)2D (35.0 vs. 24.5 pg/mL), treatment with insulin (14.9% vs. 56.7%), hypertension (77.7% vs. 100%), cardiovascular events (33.2% vs. 53.3%), and kidney failure (22.0% vs. 43.3%). In the multivariate analysis, the factors identified as independent risk factors for DR were treatment of diabetes (p = 0.001) and 25(OH)D (p = 0.025). The high risk of DR in patients receiving insulin (OR 17.01) was also noteworthy. CONCLUSIONS: Levels of 25(OH)D and treatment of diabetes were significantly associated with DR after adjusting for other risk factors. Combined levels of 25(OH)D < 16 ng/mL and levels of 1,25(OH)2D < 29 pg/mL are the variables that best predict the risk of having DR with respect to vitamin D deficiency. The risk factor with the strongest association was the treatment of type 2 diabetes mellitus. This was particularly true for patients receiving insulin, who had a greater risk of DR than those receiving insulin analogues. However, further studies are necessary before a causal relationship can be established.

RESUMO

INTRODUCTION: Hypocalcemia is the most frequent complication after thyroidectomy. The aim of this work is to identify biochemical risk factors of hypocalcemia using quick perioperative (pre and post-thyroidectomy) intact parathyroid hormone (PTHi) and postoperative calcemias. METHODS: In a consecutive series of 310 total thyroidectomies, samples of quick PTHi at the anaesthetic induction and 10 minutes after surgery, together with serum calcemias every 12 hours were obtained. The sensitivity, specificity, positive and negative predictive value are analyzed and related to hypocalcemia. A control group of hemithyroidectomies is also analyzed to compare the effects of surgery on PTH secretion. RESULTS: Of the 310 patients, 202 (65.1%) remained normocalcemic and asymptomatic (group A), 108 (34.9%) presented hypocalcemia (Group B), requiring oral calcium (79 symptomatic). After analysis of several cut-off points, combining a PTHr drop gradient of 60% or calcemia inferior to 7.4 mg/dl at 24 hours, a sensitivity of 100% is achieved without leaving false negatives. Compared to the control group, there is a significant difference with respect to the post-operative calcemias and PTHr, p < 0.001. CONCLUSIONS: Total thyroidectomy affects parathyroid function with evident decrease in rPTH and risk of hypocalcemia. The combination of PTHr decrease of 60% or less than 7.4 mg/dl calcemia at 24 hours gives a 100% sensitivity for predicting patients at risk of hypocalcemia.

RESUMO

Introduction: Improving patients' information needs (IN) may contribute to better control in COPD. This study analyses IN using Lung Information Needs Questionnaire (LINQ) following an educational intervention, evaluates how clinical characteristics modify IN, and studies high IN as a prognostic factor for COPD exacerbations and hospital admissions. Methods: Cohort of 143 patients with initial diagnosis of COPD included in a structured educational program. Two months after completing the program, IN was assessed using LINQ. Correlations between IN and clinical variables of COPD and distribution of IN in different clinical groups were analyzed. Univariate and multivariate analysis was performed to determine influence of IN on exacerbations and COPD admissions over the following year. Results: LINQ scored 6.3±2.9. There were no differences in LINQ scoring between different clinical groups, but LINQ score positively correlated with age (r=0.184, p=0.029). High IN was a predictor of COPD hospitalizations (HR 2.3 [95% CI 1.1-5.1] (p=0.029)) but not of less severe exacerbations (p=0.334). Conclusion: IN was not associated with any clinical variables, but it correlated with age. High IN proved to be an independent predictor of admissions.

RESUMO

OBJECTIVE: To analyse a cohort of pregnant patients with systemic lupus erythematosus and compare the outcomes of both the disease and pregnancy with the results of previous studies conducted in the same geographical area. PATIENTS AND METHODS: Retrospective cohort study of 37 women with systemic lupus erythematosus (64 pregnancies) followed in a multidisciplinary unit. Comparative study with similar Spanish studies identified after literature search. RESULTS: Our cohort was characterized by an older age and by the presence of non-Caucasian patients. Although we found no clinical differences, from the serological point of view our cohort presented a higher frequency of antiphospholipid antibodies. Patients included in this study were treated more frequently with antimalarials and low-dose aspirin. Systemic lupus erythematosus flare frequency was very similar between the different studies, and we did not identify clear predictors for them. Although the rate of live births was similar among studies, the obstetric outcome of our series was better with a very low rate of preeclampsia, preterm birth and low birth weight newborn. The only predictor of adverse obstetric event was age. CONCLUSIONS: Although changes in the therapeutic attitude and planning of pregnancy in recent years have not had a direct impact on the rate of systemic lupus erythematosus flares during pregnancy, they have meant an improvement in the obstetric results. The introduction of new variables independent of the disease such as age at conception, socio-cultural origin, or the availability of multidisciplinary units should be considered in the results of future studies.

RESUMO

INTRODUCTION: Introduction: the aging of S panish population has increased in the last decades; in Santander, 24,73 % of the population are elderly people. Adherence to the recommendations for a healthy diet in this group has been associated with improved health status and quality of life. Objectives: to assess the degree of adherence to the recommendations issued by the Healthy Eating Guide for Primary Care and Citizen Groups of the SENC (2018) in a non-institutionalized population sample between 65 and 79 years of age in the municipality of Santander (Spain). Methods: this was a cross-sectional, observational and descriptive study. A total of 317 individuals aged 71.8 (± 4.1) years, attending three Primary Care Centers (CAP) of the Cantabrian Health Service (SCS), participated. A self-developed questionnaire was extracted from the 2018 SENC Guide recommendations. The relationship between two independent qualitative variables was analyzed using the chi-squared test, considering significant a p-value < 0.05. Results: adherence to the recommendations in foods for daily consumption was: water (23 %), cereals and potatoes (12,9 %), fruits (50,2 %), vegetables (16,7 %), olive oil (61,8 %) and dairy products (39,1 %). For weekly-consumption foods it was: fish (12 %), white meats (17 %), eggs (19,9 %), legumes (75,1 %) and nuts (36,9 %). Conclusions: the results obtained show a low adherence to SENC recommendations except for legumes. For this reason, it is necessary to influence this population group in order to improve their dietary habits.


INTRODUCCIÓN: Introducción: el envejecimiento de la población española se ha incrementado en las últimas décadas; en Santander, el 24,73 % de la población son personas mayores. La adherencia a las recomendaciones de una alimentación saludable en este colectivo se ha relacionado con un mejor estado de salud y calidad de vida. Objetivos: evaluar el grado de adherencia a las recomendaciones de la Guía de Alimentación Saludable para Atención Primaria y Colectivos Ciudadanos de la SENC (2018) en un grupo de población de entre 65 y 79 años de edad, no institucionalizada, del municipio de Santander (España). Métodos: este fue un estudio transversal, observacional y descriptivo. Participaron 317 individuos de 71,8 ( 4,1) años, correspondientes a tres Centros de Atención Primaria (CAP) del Servicio Cántabro de Salud (SCS). Se cumplimentó un cuestionario de elaboración propia, extraído de las recomendaciones de la Guía de la SENC (2018). Se analizó la relación entre dos variables cualitativas independientes mediante la prueba del chi cuadrado, considerando significativo un valor p < 0,05. Resultados: la adherencia a las recomendaciones de alimentos de consumo diario fue: agua (23 %), cereales y patatas (12,9 %), frutas (50,2 %), verduras y hortalizas (16,7 %), aceite de oliva (61,8 %) y lácteos (39,1 %). En los alimentos de consumo semanal fue: pescado (12 %), carnes blancas (17 %), huevos (19,9 %), legumbres (75,1 %) y frutos secos (36,9 %). Conclusiones: los resultados obtenidos muestran una baja adherencia a las recomendaciones de la SENC, excepto en las legumbres. Por este motivo se precisa incidir en este grupo de población para mejorar sus hábitos dietéticos.
