Food insecurity was negatively associated with adherence to the "fruits, vegetables, and foods rich in animal protein" dietary pattern among university students' households: the 2018 Mexican National Household Survey.

BACKGROUND: University students are often affected by food insecurity (FI) and this situation has been associated with low consumption of fruit/vegetables and high intake of added sugars and sweet drinks. However, there needs to be more evidence on the association between FI and dietary patterns (DPs), assessing the overall diet and allowing analysis of commonly consumed food combinations. We aimed to analyze the association between FI and DPs in university students' households. METHODS: We used data from 7659 university student households from the 2018 Mexican National Household Income and Expenditure Survey (ENIGH, for its acronym in Spanish). We obtained FI levels (mild, moderate, and severe) using the validated Mexican Food Security Scale (EMSA, Spanish acronym). Two DPs were identified by principal component analysis based on the weekly frequency of consumption of 12 food groups. Multivariate logistic regression adjusted by university student and household's characteristics was applied. RESULTS: Compared to food security, households with mild-FI (OR:0.34; 95%CI:0.30, 0.40), moderate-FI (OR:0.20; 95%CI:0.16, 0.24) or severe-FI (OR:0.14; 95%CI:0.11, 0.19) were less likely to adhere to the dietary pattern "Fruits, vegetables and foods rich in animal protein" (fruits, vegetables, meat, fish or seafood, dairy products, and starchy vegetables). In addition, people with severe-FI (OR:0.51; 95% CI:0.34, 0.76) were also less likely to adhere to the dietary pattern "Traditional-Westernized" (pulses, oils or fats, sugar, sweets, industrialized drinks, foods made from corn/maize, wheat, rice, oats or bran, coffee, tea and eggs). CONCLUSIONS: In these households FI impairs the ability to consume a healthy dietary pattern (fruits/vegetables and foods rich in animal protein). In addition, the intake of foods typical of the Mexican food culture reflecting the local Western dietary pattern is compromised in households with severe-FI.

Effect of flaxseed (Linum usitatissimum) supplementation on glycemic control and insulin resistance in prediabetes and type 2 diabetes: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Prediabetes and type 2 Diabetes Mellitus (T2DM) are characterized by increased blood sugar concentration and insulin resistance. Although there are only a few reports of potential benefits of flaxseed's consumption on different metabolic parameters, there is no evidence of its effect among people with these conditions. OBJECTIVES: The present systematic review and meta-analysis aimed to assess the effect of flaxseed supplementation on glycemic control variables and insulin resistance in prediabetes and T2DM. METHODS: A literature search was conducted through PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science, to identify Randomized Control Trials (RCTs) that evaluated the effect of milled or ground flaxseed supplementation on fasting blood glucose, HbA1c, insulin concentrations, or HOMA-IR. The data were analyzed using Comprehensive Meta-Analysis (CMA) software version 3.3 in a fixed-effect model. RESULTS: Seven studies were included in the systematic review and the meta-analysis, the results showed a significant reduction on fasting blood sugar (SMD: -0.392, 95% CI: -0.596, -0.187, p = <0.001, I2 = 64.81%) insulin concentrations, (SMD: -0.287, 95% CI: -0.534, -0.041, p = 0.022, I2 = 32.53%), HbA1c (SMD: -0.442, 95% CI: -0.770, -0.114, p = 0.008, I2 = 11.058%), and HOMA-IR (SMD: -0.284, 95% CI: -0.530, -0.038, p = 0.024, I2 = 0.00%) after flaxseed supplementation. CONCLUSIONS: Flaxseed supplementation seems to improve glycemic control variables and insulin resistance in prediabetes and T2DM; however, more RCTs are needed to have more decisive evidence about doses, method of supplementation, and the possible effect of synergy with the dietetic treatment.

The Reproducibility and Relative Validity of a Food Frequency Questionnaire for Identifying Iron-Related Dietary Patterns in Pregnant Women.

Analyzing pregnant women's iron intake using dietary patterns would provide information that considers dietary relationships with other nutrients and their sources. The objective of this study was to evaluate the reproducibility and relative validity of a Qualitative Food Frequency Questionnaire to identify iron-related dietary patterns (FeP-FFQ) among Mexican pregnant women. A convenience sample of pregnant women (n = 110) completed two FeP-FFQ (FeP-FFQ1 and FeP-FFQ2) and a 3-day diet record (3DDR). Foods appearing in the 3DDR were classified into the same food groupings as the FeP-FFQ, and most consumed foods were identified. Exploratory factor analysis was used to determine dietary patterns. Scores were compared (FeP-FFQ for reproducibility and FeP-FFQ1 vs. 3DDR for validity) through intraclass correlation coefficients (ICC), cross-classification, Bland−Altman analysis, and weighed Cohen kappa (κw), using dietary patterns scores tertiles. Two dietary patterns were identified: "healthy" and "processed foods and dairy". ICCs (p < 0.01) for "healthy" pattern and "processed foods and dairy" pattern were 0.76 for and 0.71 for reproducibility, and 0.36 and 0.37 for validity, respectively. Cross-classification and Bland−Altman analysis showed good agreement for reproducibility and validity; κw values showed moderate agreement for reproducibility and low agreement for validity. In conclusion, the FeP-FFQ showed good indicators of reproducibility and validity to identify dietary patterns related to iron intake among pregnant women.

Emotional Eating and Dietary Patterns: Reflecting Food Choices in People with and without Abdominal Obesity.

Emotional eating (EE) is food consumption in response to feelings rather than hunger. EE is related to unhealthy food intake and abdominal obesity (AO). However, little evidence exists about the association between EE and dietary patterns (DPs) and EE−AO interaction related to DPs. DPs allow describing food combinations that people usually eat. We analyzed the association of EE with DPs in adults (≥18 years) with AO (WC ≥ 80/90 cm in women/men, respectively; n = 494; 66.8% women;) or without AO (n = 269; 74.2% women) in a cross-sectional study. Principal component analysis allowed identifying four DPs from 40 food groups (validated with a semiquantitative food frequency questionnaire). Among the subjects presenting AO, being "emotional/very-emotional eater" (emotional eating questionnaire) was negatively associated with the "Healthy" DP (fruits, vegetables, olive oil, oilseeds, legumes, fish, seafood) (OR:0.53; 95% CI: 0.33, 0.88, p = 0.013) and positively with the "Snacks and fast food" DP (sweet bread, breakfast cereal, corn, potato, desserts, sweets, sugar, fast food) (OR:1.88; 95% CI: 1.17, 3.03, p = 0.010). Emotional eaters with AO have significantly lower fiber intake, folic acid, magnesium, potassium, vitamin B1, and vitamin C, while they had a higher intake of sodium, lipids, mono and polyunsaturated fatty acids, and saturated fats. In non-AO participants, EE was not associated with any DP (p > 0.05). In conclusion, EE is associated with unhealthy DPs in subjects with AO.

Prevalence and Risk Factors of Food Insecurity among Mexican University Students' Households.

Household food insecurity (FI) remains a major public health challenge worldwide. Data about perceived FI and its risk factors in Mexican university students are lacking. We aimed to assess FI's prevalence and factors affecting it among university students' households in Mexico. This cross-sectional analysis involved 7671 university students' households using the 2018 Mexican National of Household Income and Expenditure Survey data. Variables analyzed included sociodemographic characteristics, and the 12-item validated Mexican Scale for Food Security (EMSA). Multivariable logistic regression modelling was performed to identify FI risk factors. The overall household FI prevalence was 30.8%. According to FI severity, prevalence rates were 16.3% for mild-FI, 8.8% for moderate-FI, and 5.7% for severe-FI. Low socioeconomic status (OR = 2.72; 95%CI: 2.09-3.54), low education level of household's head (OR = 2.36; 95%CI: 1.90-2.94), self-ascription to an indigenous group (OR = 1.59; 95%CI: 1.41-1.79), attending public university (OR = 1.27; 95%CI: 1.13-1.43), female-headed household (OR = 1.26; 95%CI: 1.13-1.40), having worked recently (OR = 1.19; 95%CI: 1.07-1.33), and being in second year of studies (OR = 1.17; 95%CI: 1.03-1.33), were significantly related to FI. Our results confirm that FI is highly prevalent among Mexican university students' households and that sociodemographic factors are essential in addressing this concern. Findings highlight the need for preventive programs and policies to alleviate FI.

Social Representations of Drinking Water in Schoolchildren and Parents from Two Schools in Zapopan, Mexico.

Childhood obesity and children being overweight has increased recently; although they are multi-causal problems, an unhealthy diet is a critical component. In Mexico, drinking water consumption in children from 9 to 18 years only reaches 30% of total fluid consumption. The aim of our study was to describe the social representations (SR) of drinking water in school-children and parents of two schools in Zapopan, Mexico. Associative free listing was used as an information gathering technique. Schoolchildren aged 8 to 12 years (n = 50) and parents (n = 23) from two elementary schools were selected by a convenience sampling from April to June 2015. A similarity analysis was performed using the co-occurrence index; with this, a similarity graph was obtained. Prototypical analysis was performed to explore the structure of the SR. Three dimensions were described in the children's SR: a functional dimension related to health and nutrition, a practical dimension that describes the instruments used for its consumption, and a theoretical dimension that specifies the characteristics of water and its relationship with nature. In the parents' SR, a functional dimension was also found; another dimension was described regarding the integral well-being that drinking water provides. A practical dimension describes the features related to its consumption. The investigation describes the structure of the water SR, which help to contextualize and explain the actions of schoolchildren and their parents regarding drinking water consumption.

Second Version of a Mini-Survey to Evaluate Food Intake Quality (Mini-ECCA v.2): Reproducibility and Ability to Identify Dietary Patterns in University Students.

Evaluation of food intake quality using validated tools makes it possible to give individuals or populations recommendations for improving their diet. This study's objective was to evaluate the reproducibility and ability to identify dietary patterns of the second version of the Mini Food Intake Quality Survey (Mini-ECCA v.2). The survey was administered using a remote voting system on two occasions with four-week intervals between administrations to 276 health science students (average age = 20.1 ± 3.1 years; 68% women). We then performed a per-question weighted kappa calculation, a cluster analysis, an ANOVA test by questionnaire item and between identified clusters, and a discriminant analysis. Moderate to excellent agreement was observed (weighted κ = 0.422-0.662). The cluster analysis identified three groups, and the discriminant analysis obtained three classification functions (85.9% of cases were correctly classified): group 1 (19.9%) was characterized by higher intake of water, vegetables, fruit, fats, oilseeds/avocado, meat and legumes (healthy food intake); group 2 (47.1%) frequently consumed both fish and unhealthy fats (habits in need of improvement); group 3 (33%) frequently consumed sweetened beverages, foods not prepared at home, processed foods, refined cereals and alcohol (unhealthy food intake). In conclusion, the Mini-ECCA v.2 has moderate to excellent agreement, and it is able to identify dietary patterns in university students.

Design and Reproducibility of a Mini-Survey to Evaluate the Quality of Food Intake (Mini-ECCA) in a Mexican Population.

Evaluating food intake quality may contribute to the development of nutrition programs. In Mexico, there are no screening tools that can be administered quickly for the evaluation of this variable. The aim was to determine the reproducibility of a mini-survey designed to evaluate the quality of food intake (Mini-ECCA) in a Mexican population. Mini-ECCA consists of 12 questions that are based on Mexican and international recommendations for food and non-alcoholic beverage intake, with the support of photographs for food quantity estimation. Each question scores as 0 (unhealthy) or 1 (healthy), and the final score undergoes a classification procedure. Through the framework of a nutritional study, 152 employees of the municipal water company in Guadalajara, Mexico (April⁻August 2016), were invited to participate. The survey was administered in two rounds (test and retest) with a 15-day interval between them. We calculated the Spearman correlation coefficient, the intra-class correlation coefficient (ICC), and weighted kappa for score classification agreement (SPSS versus 14 p < 0.05 was considered statistically significant). The survey obtained a “good” reproducibility (ρ = 0.713, p < 0.001), and an excellent concordance (ICC = 0.841 Confidence Interval 95% 0.779, 0.885). It can thus be said that the Mini-ECCA displayed acceptable reproducibility and is suitable for the purpose of dietary assessment and guidance.

EFFECTS OF A DIETARY SUPPLEMENT ON THE INCIDENCE OF ACUTE RESPIRATORY INFECTIONS IN SUSCEPTIBLE ADULTS: A RANDOMIZED CONTROLLED TRIAL.

INTRODUCTION: although supplementation of specific micronutrients may improve immunologic factors, few studies about the combination of micronutrients with plant extracts on the occurrence of acute respiratory infections (ARI) have been published. OBJECTIVES: to assess the effect of a nutritional supplement with micronutrients and plant extracts on the incidence of ARI in susceptible adults between January and April, 2012. METHODS: a randomized, double-blind, parallel, placebo- controlled clinical trial was performed. Participants were adults susceptible to ARI who were healthy at the time of evaluation, signed informed consent forms and were not taking medication. They completed a medical history; weight, height, vital signs and laboratory analyses were assessed. Subjects were randomly assigned for consumption of the supplement or a placebo, for a 90 days period. Subjects made daily diary entries indicating the presence ARI symptoms. Those who became ill notified researchers and the attending physician confirmed the presence of an infection. Fisher's exact test was used to compare the proportion of ill subjects between groups. Relative risk and risk difference were also calculated (p < 0.05 significant). RESULTS: of 59 included subjects, 45 (25 women) completed the study (21 in the supplemented group and 24 in the placebo group). There were no significant differences at baseline between groups. After the intervention, the supplemented group had a lower incidence of ARI compared with the placebo group (57.1% vs. 91.7%, p = 0.013, RR = 0.62, 95%CI 0.42, 0.92). DISCUSSION: the consumption of a supplement with vitamins, minerals and plant extracts may decrease the incidence of ARI in susceptible adults.

Introducción: aunque la suplementación de micronutrientes específicos puede mejorar determinados factores inmunológicos, han sido publicados pocos estudios sobre la combinación de micronutrientes con extractos herbales y la incidencia de infecciones respiratorias agudas (ARI) . Objetivos: evaluar el efecto de un suplemento alimenticio con micronutrientes y extractos herbales en la incidencia de ARI en adultos susceptibles, en enero-abril de 2012. Métodos: se realizó un ensayo clínico paralelo, aleatorizado, doble ciego, controlado con placebo. Se incluyeron adultos susceptibles a ARI, sanos en el momento de la evaluación, que firmaron un consentimiento informado y que no tomaban medicamentos. Completaron una historia clínica y se evaluó: peso, talla, signos vitales y de laboratorio. Se asignaron aleatoriamente para consumir durante 90 días el suplemento o un placebo. Los sujetos registraron diariamente si presentaban o no síntomas de ARI en un diario. En caso de enfermedad, se lo notificaron a los investigadores y el médico responsable confirmó la presencia de infección. Se utilizó la prueba exacta de Fisher para comparar la proporción de enfermos entre los grupos y se calculó el riesgo relativo y la diferencia de riesgos (p < 0,05 significativa). Resultados: de 59 sujetos incluidos, 45 (25 mujeres) completaron el estudio (21 del grupo suplementado y 24 del placebo). No hubo diferencias significativas al inicio entre grupos. Al finalizar la intervención, el grupo suplementado tuvo una menor incidencia de ARI en comparación con el placebo (57,1% vs 91,7%, p = 0,013, RR = 0,62, IC95% 0,42, 0,92). Discusión: en conclusión, el consumo de un suplemento a base de micronutrientes y extractos herbales puede disminuir la incidencia de ARI en adultos susceptibles.

[Design and validation of a questionnaire to assess dietary behavior in Mexican students in the area of health]. / Diseño y validación de un cuestionario para evaluar el comportamiento alimentario en estudiantes Mexicanos del área de la salud.

INTRODUCTION: The dietary behavior (DB) establishes the relationship between the human being and foods and has an influence on nutrient intake and, therefore, it contributes to the health or disease status of a population, even among college students. There exit some validated instruments to assess food and nutrients intake, but there are very few assessing DB. OBJECTIVE: To design and validate a questionnaire to assess DB in Mexican college students. METHODS: According to the literature and Reasoned Theory, a questionnaire assessing DB was designed. Its logic and content validity was determined by expert assessment. It was applied on two occasions with a 4-week interval to 333 students from the University of Guadalajara coursing the sixth semester of Medicine or Nutrition. The reproducibility was assessed by means of the interclass correlation coefficient. The construct validity and the internal consistency were calculated by Rasch analysis, for both the difficulty of the items and the subjects' capability. RESULTS: The questionnaire finally included 31 questions with multiple choice answers. The interclass correlation coefficient of the instrument was 0.76. The Cronbach alpha was 0.50 for the subjects' capability and 0.98 for the internal consistency of the items. 87.1% of the subjects and 89.8% of the items had INFIT and OUTFIT values within acceptable limits. CONCLUSIONS: The present questionnaire has the potentiality of measuring at low cost and in a practical way aspects related with DB in college student with the aim of establishing or following-up corrective or preventive actions.

INTRODUCCIÓN: El comportamiento alimentario (CA), que establece la relación del ser humano con los alimentos, influye en el consumo de nutrimentos y por tanto contribuye al estado de salud o enfermedad de la población, incluso en jóvenes universitarios. Existen algunos instrumentos validados para evaluar el consumo de alimentos y nutrimentos, pero son escasos los que valoran el CA. OBJETIVO: Diseñar y validar un cuestionario para valorar el CA en estudiantes universitarios mexicanos. MÉTODOS: Con base en la literatura existente y se diseñó un cuestionario para evaluar el CA. Se determinó su lógica y validez de contenido mediante la evaluación por expertos. Se aplicó en dos ocasiones con un intervalo de 4 semanas a 333 estudiantes del sexto semestre de dos licenciaturas (Medicina y Nutrición) de la Universidad de Guadalajara. Se determinó su reproducibilidad mediante el coeficiente de correlación intraclase. Su validez de constructo y consistencia interna se calculó a través del análisis Rasch, tanto para la dificultad de los ítems como para la habilidad de los sujetos. RESULTADOS: El cuestionario quedó integrado por 31 preguntas con opción de respuesta múltiple.El coeficiente de correlación intraclase fue de 0,76 para la reproducibilidad del instrumento. Se obtuvo un alfa de Cronbach de 0,50 para la habilidad de los sujetos y de 0,98 para la consistencia interna de los ítems. El 87,1% de los sujetos y el 89,8% de los ítems tuvieron valores de INFIT y OUTFIT dentro de los valores aceptables. CONCLUSIONES: El presente cuestionario tiene el potencial de medir a bajo costo y de forma práctica aspectos del CA en universitarios, con el propósito de establecer o dar seguimiento a acciones correctivas o preventivas.
