Background and aims Olive oil and components might have a beneficial effect on Metabolic Syndrome (MetS). The aim of this review and meta-analysis was to assess whether those effects are related to hydroxytyrosol or oleic acid contents, or the combination of them as olive oil, and how powerful is this effect. Methods A systematic literature search was performed in MEDLINE via Pubmed, Web of Science (WOS) core collection, and Virtual Health Library (VHL) via LILACS and IBECS (Spain). MeSH terms used were “obesity”, “body weight”, “body mass index”, “adipose tissue”, “lipid metabolism”, “LDL”, “HDL”, “VLDL”, “insulin resistance”, “glucose”, “insulin”, “hypertension”, “arterial pressure”, “olive oil”, “oleic acid”, and other (non-MeSH) terms: “total antioxidant capacity”, “total antioxidant status”, “hydroxytyrosol” (PROSPERO ID: CRD42021247614). Results of the included studies were meta-analyzed with the RevMan 5.3 program, assuming a random effects model. Results 76 articles (67 different trials) were identified. Hydroxytyrosol had no effect on MetS [combined standardized mean differences (SMD) = 0.01 (CI 95%: [-0.23, 0.25], I2 = 83%; p = 0.920)]. Oleic acid had no significant beneficial effect on MetS [SMD = 0.03 (CI 95%: [-0.01, 0.07], I2 = 0%); p = 0.150], but it improved lipid profile [SMD = 0.06 (CI 95%: [-0.00, 0.12], I2 = 0%); p = 0. 050]. Olive oil had no effect on MetS [SMD = −0.01 (CI 95%: [-0.05, 0.03]), I2 = 55%; p = 0.550)]. The supplementation with hydroxytyrosol, oleic acid or olive oil showed a beneficial effect on antioxidant capacity related to components of MetS [SMD = 0.31 (CI 95%: [-0.34, 0.95], I2 = 81%)]; p = 0.35). Conclusion Most articles compared olive oil and oleic acid with other strategies specially designed for MetS management. Our findings suggest that olive oil or oleic acid consumption are as good as the other strategies to manage MetS.

Research related to sustainable diets is is highly relevant to provide better understanding of the impact of dietary intake on the health and the environment.To assess the association between the adherence to an energy-restricted Mediterranean diet and the amount of COUsing a cross-sectional design, the association between the adherence to an energy-reduced Mediterranean Diet (erMedDiet) score and dietary COFood intake and adherence to the erMedDiet was assessed using validated food frequency questionnaire and 17-item Mediterranean questionnaire. Sociodemographic characteristics were documented. Environmental impact was calculated through greenhouse gas emissions estimations, specifically COMore men than women induced higher dietary levels of COThe Mediterranean diet can be environmentally protective since the higher the adherence to the Mediterranean diet, the lower total dietary CO

The menopausal transition stage brings physiological changes associated with the development of metabolic syndrome (MetS), which can affect bone mineral density (BMD), and may be more evident in the postmenopausal stage. The aim of this study was assessing the association between low BMD and MetS and its components among reproductive/menopausal transition and postmenopausal women in the northeast region of Mexico. A descriptive cross-sectional study was carried out (2015–2016) in 40–60-year-old women (n = 376) who were residents in the metropolitan area of Monterrey, in Nuevo Leon State, Mexico. Anthropometric measurements, blood pressure, a dual-energy X-ray absorptiometry (DXA) evaluation of BMD of two anatomical sites (lumbar spine and dual femur), and a biochemical analysis were obtained. The prevalence of MetS was 57.2%. In participants without MetS, the prevalence of osteopenia was 27.3% in the lumbar spine and 18.6% in the dual femur, while in participants with MetS, the prevalence of osteopenia was 35.8% in the lumbar spine and 14.4% in the dual femur. Osteoporosis in participants without MetS was present in 6.8% in the lumbar spine and in 1.8% in the dual femur, while in women with MetS, its prevalence was 4.7% in the lumbar spine and 0.5% in the dual femur. An association between low BMD at the lumbar spine and dual femur and components of MetS diseases was identified in Mexican women as follows: waist circumference ≥ 88 cm showed an increase risk for low BMD at femoral site in both reproductive/menopausal transition (OR 7.638, 95% CI: 1.607–36.298, p = 0.011) and postmenopausal women (OR 2.600, 95% CI: 1.023–6.609, p = 0.045), HDL &lt, 50 mg/dL was associated with low BMD in both the femur (OR 3.639, 95% CI: 1.039–12.743, p = 0.043) and lumbar spine (OR 2.654, 95% CI: 1.092–6.447, p = 0.031), hypertension in postmenopausal women increased the risk for low BMD in the femur (OR 2.634, 95% CI: 1.150–6.035, p = 0.022). In conclusion, we found that components of the MetS were associated with low BMD, thus indicating that MetS increases the risk for developing osteopenia or osteoporosis. Furthermore, age was found to be an independent risk factor for low BMD.

Background: The use of health services is a complex behavioral phenomenon affected by multiple factors (availability, distance, cost, quality, attitudes, cultural beliefs, socioeconomic characteristics, and individuals’ self-perception of health). Mexico has a segmented health system, and the access to it depends on the labor insertion and the population’s ability to pay. Objective: To assess association between use of health services and cardiovascular and metabolic syndrome risk factors among Mexican adults. Methods: Analytical cross-sectional nationally representative study carried out on Mexican adults (≥20-year-old adults of both sexes, n = 4595). Socioeconomic factors, geographic area, health care coverage, information about the use of health services, previous medical diagnoses of diabetes and hypertension, and smoking were assessed. Anthropometrics, triglyceride, total cholesterol, HDL-cholesterol, and glucose plasma levels were measured. Metabolic syndrome (MetS) and cardiovascular risk factors were assessed. Prevalences were expressed in terms of percentages, and significant differences were calculated using χ2 test. Univariate and multivariate analysis was performed to evaluate the association between the use of health services and cardiovascular risk factors and sociodemographic variables. Results: The probability of using health services is higher and more significant in subjects with obesity, diabetes (OR (95% CI): 1.73 (1.49–2.00, p &lt, 0.001), hypertension (OR (95% CI): 1.29 (1.14–1.45, 0.001), hypertriglyceridemia (OR (95% CI): 1.30 (1.15–1.46, 0.001), and in those with hypercholesterolemia (OR (95% CI): 1.23 (1.03–1.39, p = 0.001). Conclusions: Among health service users, there is a positive significant association between the use of health services and the presence of metabolic syndrome, obesity, diabetes, hypertension, hypertriglyceridemia, and hypercholesterolemia.

Background: Adoption of a certain dietary pattern is determined by different factors such as taste, cost, convenience, and nutritional value of food. Objective: To assess the association between the daily cost of a diet and its overall quality in a cohort of 6–12-year-old Spanish schoolchildren. Methods: A cross-sectional survey was conducted on a cohort (n = 130, 47% female) of 6–12-year-old children schooled in primary education in the central region of Spain. Three-day 24 h records were administered, and the nutritional quality of the diet was also determined by means of Mediterranean Adequacy Index (MAI). A questionnaire on sociodemographic data, frequency of eating in fast-food restaurants, and supplement intake were also recorded. The person responsible for the child’s diet and the schooler himself completed the questionnaires, and homemade measures were used to estimate the size of the portions. Food prices were obtained from the Household Consumption Database of the Spanish Ministry of Agriculture, Fisheries and Food. The economic cost of the diet was calculated by multiplying the amount in grams of the food consumed by each child by the corresponding price in grams and adding up the total amount for each participant. The total economic cost of the diet was calculated in €/day and in €/1000 kcal/day. Results: The area under the curve (AUC) for €/day and €/1000 kcal/day represent 62.6% and 65.6%, respectively. According to AUC values, adherence to Mediterranean diet (MD) is a moderate predictor of the monetary cost of the diet. A direct relationship between the cost of the diet and the adherence to MD was observed [OR (€/1000 kcal/day) = 3.012, CI (95%): 1.291, 7.026, p = 0.011]. Conclusions: In a cohort of Spanish schoolchildren with low adherence to the MD, a higher cost of the diet standardized to 1000 kcal was associated with above-average MAI values.

Vasomotor symptoms (VMS) are the most common symptoms among menopausal women; these include hot flashes and night sweats, and palpitations often occur along with hot flashes. Some studies in Mexico reported that around 50% of women presented with VMS mainly in the menopausal transition. It has been proven that VMS are not only triggered by an estrogen deficiency, but also by nutritional risk factors. Evidence of an association between nutritional risk factors and VMS is limited in Mexican women. The aim of this study is to identify nutritional risk factors associated with VMS in women aged 40–65 years. This is a comparative cross-sectional study, undertaken in a retrospective way. A sample group (n = 406 women) was divided into four stages according to STRAW+10 (Stages of Reproductive Aging Workshop): late reproductive, menopausal transition, early postmenopause, and late postmenopause. Hot flashes were present mainly in the early postmenopause stage (38.1%, p ≤ 0.001). Two or more VMS were reported in 23.2% of women in the menopausal transition stage and 29.3% in the early postmenopause stage (p < 0.001). The presence of VMS was associated with different nutritional risk factors (weight, fasting glucose levels, cardiorespiratory fitness, and tobacco use) in women living in the northeast of Mexico.

Background: Health-related quality of life (HRQoL) allows knowing the subject’s feelings in distress and well-being, as well as perception of current and future health. Objective: To assess associations between health-related quality of life, fitness status, and adherence to the Mediterranean diet in Spanish children and adolescents. Methods: A cross-sectional study was carried out in a sample of 305 (47.2% women) children and adolescents aged between 8 and 16 years, in the primary and secondary schools of the province of Ávila (central Spain) (NCT05380674). Subjects were classified according to their quality of life: group 1 (highest quality of life) > group 2 (medium quality of life) > group 3 (lowest quality of life). Results: More participants in group 1 showed higher adherence to Mediterranean diet (70.8%) than other groups (group 2: 55.0%; group 3: 43.4%). It was less likely to find optimal levels of muscle strength as quality of life decreased (OR; 95% CI: group 2: 0.535; 0.303–0.955; and group 3: 0.424; 0.234–0.768). Similar trends were found for speed and agility, but only group 3 showed significant results (OR; 95% CI: group 3: 0.297; 0.162–0.545). Flexibility was also the worst in groups 2 and 3 (OR; 95% CI: G2: 0.403; 0.213–0.762; and group 3: 0.520; 0.282–0.958). Conclusion: High fitness status and adherence to the Mediterranean diet were associated with improved health-related quality of life in schoolchildren of central Spain.

Objetivos: Analizar los principales patrones de consumo de alimentos de los estudiantes universitarios de Zamora y su asociación con los diferentes grupos de alimentos.Métodos: Estudio transversal, descriptivo y observacional sobre una muestra representativa de los estudiantes universitarios de la provincia de Zamora (n=213; 18-29 años). El consumo de alimentos se determinó mediante un cuestionario validado semicuantitativo de frecuencia de consumo, que incluía 64 alimentos, reunidos en 13 grupos. Los patrones de consumo se determinaron por análisis factorial.Resultados: Los estudiantes universitarios de Zamora muestran dos patrones de consumo: “Mediterráneo”, que explica un 19.4% de la varianza total y se caracteriza por un consumo de lácteos, pescado y mariscos, carnes y legumbres, embutidos, cereales y tubérculos, fruta y verduras y aceite de oliva, y “Occidental”, que explica un 22.2% de la varianza total y se caracteriza por un consumo de lácteos, huevos, carnes y legumbres, embutidos, frutos secos, otras grasas distintas del aceite de oliva, bollería y dulces, alimentos preparados y bebidas azucaradas, con bajo consumo de fruta y verduras. El análisis factorial presenta una medida de adecuación de la muestra (KMO) de 0.615. Conclusiones: Los estudiantes universitarios de Zamora se encuentran en de transición nutricional, con una dieta que se aleja de las recomendaciones de la Dieta Mediterránea.

Purpose: The main objective was to evaluate the usefulness of early ultrasonography for determining prognosis Ultrasonography schemic colitis of patients with ischemic colitis. Materials and methods: We reviewed the histories of patients with diagnosis of ischemic colitis over a period of 11 years. Two hundred twenty nine patients with ischemic colitis were included. Demographic, clinical, laboratory and sonographic findings were retrospectively analyzed. Patients were divided into two groups according to the outcome: mild (those who improved with conservative treatment) or severe (those who died or required surgery), and the findings of each group were compared. In addition, we developed a predictive model of multivariate logistic regression analysis, and then it was validated in a different population of 58 consecutive patients with ischemic colitis. Results: The mild ischemic colitis group consisted of 184 patients (age 74,7 +/- 8,8 years), and the severe group of 45 patients (age 78,6 7,7 years). More pancolitis (p = 0.005), altered pericolic fat (p = 0.032) and free fluid (p = 0.013) was observed in the severe ischemic colitis group compared with the mild group. Severe ischemic group had lower wall thickness (p = 0.020) and higher resistive index than mild group (p = 0.025). Multivariate analysis identified as protective factors to severe ischemic colitis: pain (p = 0.026), diarrhea (p = 0.034), rectal bleeding (p = 0.000), and hypertension (p = 0.001). Altered pericolic fat (p = 0.008) and pancolitis (p = 0.017) were sonographic findings significantly related to severe ischemic colitis. Our model correctly classified 88.4% of the study patients and 89.6% of the population of 58 patients used in validation. Conclusions: Sonographic features with clinical findings can predict the outcome of ischemic colitis. Our predictive model could differentiate properly between patients with mild or severe ischemic colitis.
