SESSAMO, follow-up of secondary students to assess mental health and obesity: a cohort study.

During last decades, a departure from health-related lifestyles has been observed among adolescents. Evidence reports that healthy lifestyles could be predictors of better mental health status. The aims of the SESSAMO Project are: 1) to assess the association between lifestyles and physical and mental health; 2) to assess how self-concept and stressful life events can modulate these associations; and 3) to establish the role of social determinants in the lifestyle and in adolescents' health. The SESSAMO Project is a prospective cohort carried out in Spain. Students aged 14-16 years (2nd-4th ESO) and their parents are invited to participate. Baseline data are collected through on-line, validated, self-administered questionnaires through a digital platform. Information on lifestyles, stressful life events and self-concept are collected. Screening of depression, anxiety, eating disorders, suicide risk, psychotic experiences and COVID impact is assessed. Every three years, up to age of 25, participants will be contacted again to update relevant information.

Daily time spent on screens and psychological well-being: Cross-sectional association within the SUN cohort.

BACKGROUND: The impact of various lifestyles on psychological well-being (PWB) remains under-studied. We aimed to explore the cross-sectional association between daily screen use (television, tablet and mobile phone) and PWB within the SUN cohort. METHODS: PWB was assessed using the 29-item Ryff scale (ranging from 29 to 174), and participants with scores >75th percentile were considered as having optimal PWB. Participants were categorized based on their self-reported weekly screen usage hours. Postestimation logistic regression models assessing the prevalence likelihood of not achieving optimal PWB were adjusted for sociodemographic, psychological, personality and lifestyles factors. Isotemporal substitution models explored the potential impact on PWB resulting from replacing 1 h/day of screen time with 1 h/day of exercise. RESULTS: The study included 3051 participants (55.8% women, mean age 57.3 ± 11.1 years, mean Ryff's score: 139.1 ± 17.4 points). Daily screen use for ≥2 h was associated with a higher prevalence likelihood of not achieving an optimal PWB (Prevalence Ratio [PR]:1.09; 95% CI:1.01-1.18). Among PWB dimensions, screen use ≥2 h/day was linked to an increased likelihood of not achieving optimal scores in environmental mastery (PR:1.11; 95% CI:1.02-1.20), life purpose (PR:1.10; 95% CI:1.02-1.18), and personal growth (PR:1.09; 95% CI:1.01-1.18). Replacing 1 h of daily screens time with 1 h of exercise may lead to potential improvements in environmental mastery (Odds Ratio [OR]:0.87; 95% CI:0.76-0.99), purpose in life (OR:0.86; 95% CI: 0.76-0.98), personal growth (OR:0.84; 95% CI:0.73-0.96) and positive interpersonal relationships (OR:0.86; 95% CI:0.75-0.99). CONCLUSIONS: These findings highlight the importance of reducing screen use activities and increasing physical exercise for achieving optimal PWB.

Tobacco and alcohol co-use: Lifestyle and sociodemographic factors, and personality aspects as potential predictors in the "Seguimiento Universidad de Navarra" cohort.

Tobacco and alcohol co-use are two major lifestyle modifiable risk factors. Understanding the determinants of both behaviors helps to develop interventions to prevent these exposures. However, previous studies have focused on predictors of individual tobacco or alcohol use. This study aims to explore the potential predictors of tobacco and alcohol co-use among Spanish university graduates from the "Seguimiento Universidad de Navarra" (SUN) cohort study. A total of 7175 participants who were co-users of tobacco and alcohol were selected for this cross-sectional analysis. Their mean age was 39.1 years (12.04 SD) and 57.3% were women. Univariate regression models were used to select the potential predictors of tobacco and alcohol co-use, and the areas under the ROC curves (AUC) were calculated. Multivariable logistic regression models were used to create a predictive model. Baseline potential predictors included sociodemographic factors, lifestyle habits, and perceived personality aspects. In the multivariable model, the main significant potential predictors of tobacco and alcohol co-use were driving under the influence of alcohol (odds ratio [OR] = 1.65 [1.43-1.90]), drinking 1-2 cups of coffee daily (OR = 1.50 [1.24-1.84]), drinking three or more cups of coffee daily (OR = 1.61 [1.35-1.91]), and doing more physical activity than recommended (OR = 1.18 [1.02-1.34]) when compared with the reference group. Conversely, those who were married (OR = 0.87 [0.75-0.99], ate at home 7 days a week (OR = 0.69 [0.60-0.80]), or had a high perceived level of competitiveness (OR = 0.83 [0.72-0.95]) had a lower risk of co-use (AUC 0.61 [confidence interval 95% 0.59-0.63]), compared to the reference group. These results could be used by healthcare professionals, especially nurses, to effectively assess patients at higher risk of tobacco and alcohol co-use.

En las últimas décadas se ha producido un alejamiento de los estilos de vida saludables en adolescentes. Los hábitos saludables pueden predecir una mejor salud mental. El proyecto SESSAMO tiene como objetivos: 1) determinar la asociación entre el estilo de vida y la salud física y mental; 2) determinar cómo el autoconcepto y los acontecimientos vitales estresantes pueden modular dichas asociaciones; y 3) establecer el papel de los determinantes sociales en el estilo de vida y en la salud de los adolescentes. Se trata de un estudio de cohortes prospectivo, dirigido a estudiantes de secundaria de 14-16 años y a sus padres. Los datos basales se recogen con cuestionarios validados y autoadministrados en una plataforma on-line. Se realiza un cribado de depresión, ansiedad, trastornos alimentarios, riesgo de suicidio, experiencias psicóticas e impacto de la COVID-19. Cada 3 años, hasta la edad de 25 años, se les volverá a contactar para actualizar la información relevante. (AU)

Asociación bidireccional entre uso de tabaco y riesgo de depresión en el estudio de cohorte SUN / Bidirectional association between tobacco use and depression risk in the SUN cohort study

Evaluamos la asociación del consumo de tabaco o su abandono con el riesgo de depresión y determinamos si presentar depresión se asoció al inicio de fumar. Diseño: estudio de cohortes prospectivo de 16.519 graduados universitarios españoles sin depresión al inicio del estudio. El consumo de tabaco se determinó al inicio y tras cuatro años de seguimiento. Los casos incidentes de depresión fueron autoinformados en los cuestionarios de seguimiento. Usamos modelos de regresión de Cox para estimar los Hazard Ratios (HR) de depresión según el nivel de tabaquismo inicial y sus cambios. Se estimaron los Odds Ratios (OR) para la asociación entre prevalencia de tabaquismo a lo largo de la vida y comienzo del hábito con modelos de regresión logística. Se observó un HR (IC 95%) para fumadores de 1,24 (1,05-1,46) en comparación con los que nunca habían fumado. Los participantes con la exposición más alta al tabaco (≥ 20 paquetes-año) tuvieron un incremento relativo del riesgo de depresión de 38%. Dejar de fumar durante los primeros cuatro años de seguimiento se asoció inversamente con la depresión (HR = 0,63; IC 95% = 0,40-0,99). Observamos un incremento significativo del riesgo de aparición de tabaquismo en los participantes con prevalencia de depresión a lo largo de la vida (OR multivariable = 1,44; IC 95% = 1,13-1,83). Encontramos una asociación bidireccional entre el consumo de tabaco y la depresión en la cohorte SUN. El control del tabaco y las campañas sanitarias de abstinencia deberían considerarse estrategias efectivas de salud pública para prevenir y manejar los trastornos depresivos. (AU)

We assessed the association of tobacco use or smoking cessation with depression risk and determined if the presence of a depressive disorder was associated with smoking onset. We conducted a prospective cohort study (SUN Project) based on 16,519 Spanish university graduates without depression at baseline. Tobacco use was determined at baseline and after four years of follow-up. Incident cases of depression were ascertained according to a previously validated report of a clinical diagnosis of depression during follow-up. Multivariable Cox regression models were used to estimate hazard ratios (HR) of depression according to previous smoking status. We used logistic regression models as a secondary analysis to estimate Odds Ratios (OR) of smoking onset during the first four years of follow-up according to lifetime depression prevalence at baseline. The multivariable HR (95% CI) for current smokers was 1.24 (1.05-1.46) as compared to participants who had never smoked. Participants with the highest exposure to tobacco (≥ 20 packsyears) had a significant 38% relative increment in depression risk. Smoking cessation during the first four years of follow-up was inversely associated with depression (HR = 0.63; 95% CI = 0.40-0.99). Finally, a significant increment in the risk of smoking onset for participants with lifetime depression prevalence was observed (multivariable OR = 1.44; 95% CI = 1.13-1.83). A bidirectional association between tobacco use and depression in the SUN cohort was found. Therefore, tobacco control and health promotion campaigns for smoking cessation could be considered as effective strategies of public health for the prevention and management of depressive disorders.

Effect of a dietary intervention based on the Mediterranean diet on the quality of life of patients recovered from depression: Analysis of the PREDIDEP randomized trial.

INTRODUCTION: There is substantial evidence supporting that improving diet quality leads to improved health-related quality of life (HRQoL). Our major aim was to assess the effectiveness of a Mediterranean diet-based nutritional intervention to improve HRQoL in the context of a secondary prevention trial of depression. Secondarily to assess its effectiveness among adults aged 60 or more years. METHODS: The PREDIDEP study is a 2-year multicentre, randomized, single-blinded nutritional trial. At baseline and at 1-year and 2-year follow-up, SF-36 health survey questionnaire was collected to evaluate participants' HRQoL (total and specific range for each of the 8 dimensions: 0 to 100 points). Mixed effect linear models were used to assess changes in HRQoL according to adherence to the Mediterranean diet. The trial was registered at ClinicalTrials.govNCT03081065. RESULTS: After 2 years of intervention, the Mediterranean Diet intervention group compared to control group (without nutritional intervention, only usual clinical care) showed an improvement in some dimensions of HRQoL such as Mental Health (7.22; 95 % CI = 2.22-12.22) (between-group difference: 6.79; 95 % CI -0.14-13.73, p = 0.055); Vitality (9.51; 95 % CI = 4.00-15.03) (between-group difference: 9.00; 95 % CI 1.75-16.25, p = 0.020); Mental Summary Component (2.83; 95 % CI = 0.55-5.11) (between-group difference: 1.17; 95 % CI = -1.96-4.30, p = 0.462); and General Health (10.70; 95 % CI = 5.58-15.81) (between-group difference: 6.20; 95 % CI = -0.89-13.28, p = 0.086). Similar results were observed for participants aged 60 or more years. CONCLUSION: The intervention based on Mediterranean diet in patients with previous depression seems to be effective in improving HRQoL, especially the mental dimensions. This effect is also observed among participants aged 60 or more years.

The Mediterranean Lifestyle and the Risk of Depression in Middle-Aged Adults.

BACKGROUND: Recent evidence has indicated a greater number of protective factors are associated with a greater decreased risk for depression and depressive symptoms compared with individual factors alone. Moreover, adherence to healthy modifiable lifestyle behaviors may lower the risk of depression regardless of underlying genetic risk. OBJECTIVES: We longitudinally evaluated the association of the Mediterranean lifestyle (MEDLIFE) with the risk of depression. METHODS: We prospectively analyzed data from 15,279 participants (6089 men and 9190 women, mean age 37 y) in the Seguimiento Universidad de Navarra cohort. The MEDLIFE index is composed of 28 items on food consumption, dietary habits, physical activity, rest, social habits, and conviviality, each of which was assigned 0 or 1 point. Final scores ranged from 0 to 28 points and were categorized into quartiles of MEDLIFE adherence. Cox proportional regression models determined the association of total MEDLIFE adherence, each item, and block with incident depression. RESULTS: After a mean follow-up of 11.7 y, 912 (6%) incident cases of depression were reported. The mean ± SD final score for MEDLIFE adherence was 11.9 ± 2.7 points. The multivariable model showed that compared with the first quartile, the second and third quartiles of MEDLIFE adherence were significantly associated with a decreased relative risk for incident depression (HR: 0.82; 95% CI: 0.69, 0.96 and HR: 0.74; 95% CI: 0.61, 0.89, respectively). The fourth quartile did not show a statistically significant association with incident depression (HR: 0.89; 95% CI: 0.73, 1.09). CONCLUSIONS: MEDLIFE adherence may decrease the risk of depression in a Spanish cohort of university graduates. Given no clear association was observed among the highest MEDLIFE adherence, future studies are warranted to better understand the nature of this association. Evidence on MEDLIFE, beyond the Mediterranean diet, may contribute toward more effective prevention strategies for depression.

Sedentary behaviors and risk of depression in the Seguimiento Universidad de Navarra cohort: the SUN Project / Comportamientos sedentarios y riesgo de depresión en la cohorte de Seguimiento Universidad de Navarra: el Proyecto SUN / Comportamentos sedentários e risco de depressão na coorte Seguimiento Universidad de Navarra: o Projeto SUN

The study aimed to prospectively examine the association between different sedentary behaviors and the risk of depression. We included 12,691 Spanish university graduates (mean age: 36.7 year; SD: 11.5), participants of the Seguimiento Universidad de Navarra cohort (the SUN Project), initially free of depression who were followed-up for a median of 10.9 years. Based on items presented in our baseline questionnaire, time spent in four sedentary behaviors (hours/day) were evaluated: overall sitting time; TV-viewing; computer use; and driving. Participants were classified as incident cases of depression if they reported a physician diagnosis of depression in at least one of the follow-up assessments conducted after the first two years of follow-up. Cox regression models were used to assess the relationship between sedentary behaviors and depression. A total of 560 incident cases of depression were identified during follow-up. We found no significant association between overall sitting time, TV-viewing or driving and risk of depression. On the other hand, computer use was directly associated with the risk of developing depression during the follow-up (p-value for trend = 0.020), with the participants in the highest quartile of computer use (3.64 to 10 hours/week) having a higher risk of developing depression (HR = 1.33; 95%CI: 1.05-1.70) than those in the lowest quartile (0 to 0.25 hours/week) after adjusting for potential confounders. Prolonged use of computer was independently associated with an increased risk of developing depression among young middle-aged adult university graduates from a Spanish cohort.

El objetivo del estudio fue examinar prospectivamente la asociación entre diferentes comportamientos sedentarios y el riesgo de depresión. Incluimos a 12.691 graduados universitarios españoles (media de edad: 36,7 años; SD: 11,5), participantes en la cohorte de Seguimiento Universidad de Navarra (Proyecto SUN), que no sufrieran depresión inicialmente y a quienes se les realizó un seguimiento durante una mediana de 10.9 años. Basados en los ítems presentados en nuestro cuestionario de línea de base, se evaluó el tiempo transcurrido con cuatro comportamientos sedentarios (horas/día): tiempo sentado en general, tiempo viendo TV, usando el ordenador, y conduciendo. Los participantes se clasificaron como casos incidentes de depresión, si informaban de un diagnóstico médico de depresión, emitido por un doctor en al menos una de las evaluaciones de seguimiento llevadas a cabo tras los dos primeros años de seguimiento. Los modelos de regresión Cox se usaron para evaluar la relación entre comportamientos sedentarios y depresión. Se identificaron un total de 560 casos incidentes de depresión durante el seguimiento. No encontramos ninguna asociación significativa entre el tiempo sentado en general, tiempo viendo TV, o conduciendo y el riesgo de depresión. Por otro lado, el uso del ordenador estuvo directamente asociado con el riesgo de desarrollar depresión durante el seguimiento (valor de p para tendencia = 0,020), con los participantes en el cuartil más alto de uso del ordenador (3,64 a 10 horas/semana) teniendo un riesgo más alto de desarrollar depresión (HR = 1,33; IC95%: 1,05-1,70), respecto a quienes estaban en el cuartil más bajo (0 a 0,25 horas/semana) tras realizar un ajuste para potenciales factores de confusión. El uso prolongado del ordenador estuvo independientemente asociado con el mayor riesgo de desarrollar depresión entre adultos jóvenes de mediana edad, graduados universitarios, procedentes de una cohorte española.

O estudo buscou examinar prospectivamente a associação entre diversos comportamentos sedentários e risco de depressão. Incluímos 12.691 indivíduos espanhóis com nível universitário (média de idade: 36,7 anos; DP: 11,5), participantes da coorte Seguimiento Universidad de Navarra (Projeto SUN), inicialmente sem depressão, que foram seguidos por uma mediana de 10,9 anos. Com base nos itens apresentados no questionário da linha de base, foram avaliados os tempos gastos em quatro comportamentos sedentários (horas/dia): total de tempo sentado e tempo assistindo televisão, usando computador e dirigindo. Os participantes eram classificados como casos incidentes de depressão quando relatavam um diagnóstico de depressão feito por médico em pelo menos uma das avaliações de seguimento após os primeiros dois anos de seguimento. Foram usados modelos de regressão Cox para avaliar a relação entre comportamentos sedentários e depressão. Foram identificados 560 casos incidentes de depressão durante o seguimento. Não encontramos associação entre total de tempo sentado, tempo assistindo TV ou dirigindo e risco de depressão. Por outro lado, o uso de computador mostrou associação direta com o risco de desenvolver depressão durante o seguimento (valor de p para tendência = 0,020), no qual os participantes no quartil mais alto de uso de computador (entre 3,64 e 10 horas/semana) tiveram o risco maior de desenvolver depressão (HR = 1,33; IC95%: 1,05-1,70) comparados com aqueles no quartil mais baixo (0 a 0,25 horas/semana), depois de ajustar para potenciais fatores de confusão. O uso prolongado do computador esteve associado de maneira independente com risco aumentado de desenvolver depressão em adultos de meia idade com nível universitário em uma coorte espanhola.

A Structural Equation Model of Achievement Emotions, Coping Strategies and Engagement-Burnout in Undergraduate Students: A Possible Underlying Mechanism in Facets of Perfectionism.

Achievement emotions that the university student experiences in the learning process can be significant in facilitating or interfering with learning. The present research looked for linear and predictive relations between university students' achievement emotions, coping strategies, and engagement-burnout, in three different learning situations (classroom, study time, and testing). Hypotheses were identified for a possible model that would analyze the two facets of perfectionism based on these relations. In the case of perfectionistic strivings, the test hypothesis was that positive emotions would predispose the use of problem-focused coping strategies and an emotional state of engagement; in the case of perfectionistic concerns, however, negative emotions would predispose the use of emotion-focused strategies and a state of burnout. A total of 654 university students participated in the study, using an online tool to complete validated questionnaires on the three study variables. All students provided informed consent and corresponding permissions. Given the ex-post facto linear design, the predictions could be verified for each situation by means of logistic regression analyses and Structural Equations Models (SEM). Empirical results lent support, in varying degree, to the proposed theoretical relations. The testing situation was of particular interest. We discuss implications for perfectionism research and for the practice of prevention, education and health care in the university setting.

Dimensions of leisure-time physical activity and risk of depression in the "Seguimiento Universidad de Navarra" (SUN) prospective cohort.

BACKGROUND: An inverse association between total leisure-time physical activity (LTPA) and depression has been previously documented in the scientific literature. Our objective was to prospectively assess the association of LTPA with the risk of depression, focusing on several dimensions of LTPA (intensity, duration and type). METHODS: The SUN (Seguimiento Universidad de Navarra) project is a prospective cohort study formed by Spanish university graduates. A total of 15,488 adults (40.2% men, mean age 37 ± 12 years) initially free of depression were assessed. A report of a validated medical diagnosis of depression or the habitual use of antidepressants (any of both) were considered as incident cases of depression. LTPA was estimated through previously validated self-reported questionnaires. Participants were classified following Physical Activity recommendations from the World Health Organization, and according to the intensity, duration and type of LTPA. Cox proportional hazards regression models were run, adjusted for demographic, lifestyle, and dietary factors, to estimate adjusted hazard ratios (HR) of depression and 95% confidence intervals (CI). RESULTS: During 163,059 person-years of follow-up we registered 870 incident cases of depression. Participants with higher total LTPA (METs-h/wk) and higher duration of LTPA (hours/wk) exhibited a lower risk of depression HR = 0.84 (95% CI: 0.72-0.99) and HR = 0.83 (0.70-0.99) respectively, whereas intensity of LTPA (MET) did not show any association with depression. CONCLUSION: Participants with higher LTPA had a lower risk of depression. The inverse association was stronger for total LPTA time than for its intensity. Higher duration of LTPA should be encouraged to prevent depression.

Ultra-processed food consumption and the incidence of depression in a Mediterranean cohort: the SUN Project.

PURPOSE: A growing body of evidence shows that consumption of ultra-processed foods (UPF) is associated with a higher risk of cardiometabolic diseases, which, in turn, have been linked to depression. This suggests that UPF might also be associated with depression, which is among the global leading causes of disability and disease. We prospectively evaluated the relationship between UPF consumption and the risk of depression in a Mediterranean cohort. METHODS: We included 14,907 Spanish university graduates [mean (SD) age: 36.7 year (11.7)] initially free of depression who were followed up for a median of 10.3 years. Consumption of UPF (industrial formulations made mostly or entirely from substances derived from foods and additives, with little, if any, intact food), as defined by the NOVA food classification system, was assessed at baseline through a validated semi-quantitative 136-item food-frequency questionnaire. Participants were classified as incident cases of depression if they reported a medical diagnosis of depression or the habitual use of antidepressant medication in at least one of the follow-up assessments conducted after the first 2 years of follow-up. Cox regression models were used to assess the relationship between UPF consumption and depression incidence. RESULTS: A total of 774 incident cases of depression were identified during follow-up. Participants in the highest quartile of UPF consumption had a higher risk of developing depression [HR (95% CI) 1.33 (1.07-1.64); p trend = 0.004] than those in the lowest quartile after adjusting for potential confounders. CONCLUSIONS: In a prospective cohort of Spanish university graduates, we found a positive association between UPF consumption and the risk of depression that was strongest among participants with low levels of physical activity.

Lifestyles and the risk of depression in the "Seguimiento Universidad de Navarra" cohort.

BACKGROUND: Lifestyles are involved in the pathogenesis of depression and many of these factors can be modified for the potential prevention of depression. Our aim was to assess the association between a healthy-lifestyle score, that includes some less-studied lifestyle indicators, and the risk of depression. METHODS: We followed 14,908 participants initially free of any history of depression in the "Seguimiento Universidad de Navarra" (SUN) cohort. Information was collected biennially from 1999 to December 2016. We calculated a healthy-lifestyle score (0-10 points), previously associated with cardioprotection, by giving one point to each of the following components: never smoking, physical activity (> 20 METs-h/week), Mediterranean diet adherence (≥ 4 points), healthy body mass index (≤ 22  kg/m2), moderate alcohol consumption (women 0.1-5 g/d; men 0.1-10 g/d of ethanol), avoidance of binge drinking (never more than 5 alcoholic drinks in a row), low television exposure (≤ 2 h/d), short afternoon nap (≤ 30 min/day), time spent with friends (>1 h/d) and working at least 40  h/week. RESULTS: During a median follow-up of 10.4 years, we observed 774 new cases of major depression among participants initially free of depression. The highest category (8-10 factors) showed a significant inverse association with a 32% relative risk reduction for depression compared to the lowest category (0-3 factors) (multivariable-adjusted hazard ratio: 0.68; 95% CI:0.49-0.95) (p for trend = 0.010). CONCLUSIONS: Adopting a healthy-lifestyle was associated with a lower risk of incident depression in the SUN cohort. This index, including ten simple healthy lifestyle habits, may be useful for a more integrative approach to depression prevention.

Use of non-steroidal anti-inflammatory drugs, aspirin and the risk of depression: The "Seguimiento Universidad de Navarra (SUN)" cohort.

BACKGROUND: The potential effect of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) to prevent depression remains largely unknown, in spite of the implication of inflammation in depression. This study aimed to investigate whether the habitual intake of aspirin and other NSAIDs was prospectively associated with a reduction in the observed incidence of depression. METHODS: A dynamic cohort including 22,564 Spanish university graduates (mean age: 37 years) initially free of depression was followed during an average of 8.7 years. Exposure to NSAIDs was assessed with specific repeated questionnaires throughout follow-up, starting in the 2-year follow-up questionnaire. Incident cases of depression were defined as either a new validated medical diagnosis of depression or reporting the initiation of habitual use of antidepressants. RESULTS: We identified 772 incident cases of depression. Regular intake of aspirin and other NSAIDs was not associated with depression risk. Only in secondary sensitivity analyses using a definition of the outcome with higher specificity (a validated medical diagnosis of depression), an inverse association of aspirin with depression was found [HR (95%CI): 0.20 (0.04-0.87)]. However, these results were non-significant after adjustment for multiple testing. LIMITATIONS: A possible underestimation of incident depression and a limited ability to detect all possible residual confounding. CONCLUSIONS: Regular use of NSAIDs was not associated with the incidence of depression. Further longitudinal controlled studies are necessary to clarify a potential role of aspirin use in depression risk.

Self-perceived level of competitiveness, tension and dependency and depression risk in the SUN cohort.

BACKGROUND: Emerging evidence suggests a possible etiologic role of certain personality traits (not necessary dysfunctional) in the risk of depression, but the longitudinal long-term available evidence is currently scarce. We longitudinally assessed whether 3 common personality traits (competitiveness, tension and dependency) were associated with the risk of depression after a maximum follow-up of 15 years. METHODS: We assessed 15,604 university graduates free of depression at baseline through a self-administered questionnaire including personality traits. Simple, Likert-type, questions with 11 possible answers ranging from 0 to 10 were used at baseline to assess the 3 personality traits. We compared participants with high scores (7-10) versus those with low scores (0-4). New medical diagnoses of depression during follow-up were used as the outcome. RESULTS: During a median follow-up of 10.1 y, we prospectively identified 902 new medical diagnoses of depression. The multivariable-adjusted hazard ratios (95% confidence intervals) for depression were 1.85 (1.52-2.24) for participants with higher baseline tension (7-10 versus 0 to 4), P-trend < 0.001; and 1.23 (1.06-1.44) for high versus low baseline dependence levels, P-trend = 0.004. Higher levels of competitiveness were marginally associated with lower risk of depression, with hazard ratio = 0.78 (0.61-1.01), P-trend = 0.105. CONCLUSION: A simple scoring system of personality traits shows an independent association with the future occurrence of depression. This finding underscores, with now prospective evidence, the importance of personality traits in the aetiology of depression and can provide a clinically useful tool for gathering valid information about depression-related personality traits.

Adherence to the Mediterranean dietary pattern and incidence of anorexia and bulimia nervosa in women: The SUN cohort.

OBJECTIVE: To our knowledge, no study has yet assessed the association between dietary patterns and incidence of eating disorders. This study aimed to assess the association between adherence to the Mediterranean dietary pattern (MDP) and incident risk of anorexia (AN) and bulimia nervosa (BN). METHODS: We conducted a prospective cohort study of 11 800 women from the Seguimiento Universidad de Navarra follow-up project. Participants were classified as having incident AN or BN if they were free of AN or BN at baseline and reported a physician-made diagnosis of AN or BN during the follow-up period. Nutritional status, lifestyle, and behavioral variables were investigated and used as covariates. A validated 136-item food frequency questionnaire and the Trichopoulou score were used to assess adherence to the MDP. RESULTS: After a median follow-up time of 9.4 y, 100 new cases of AN and BN were identified. The multivariate hazard ratio of AN and BN for the two upper categories of adherence to the MDP were 0.39 (95% CI: 0.20-0.75) and 0.32 (95% CI: 0.14-0.70; Ptrend = 0.021). Inverse dose-response relationships were found for the consumption of cereals and olive oil and marginally for polyunsaturated fatty acid intake. To address reverse causation, multivariable linear regressions were run using a cross-sectional approach between adherence to the MDP and risk of AN and BN at baseline. No difference in adherence was found between participants with and without eating disorders. CONCLUSIONS: Our results suggest a potential inverse association between the MDP and the risk of AN and BN. Additional longitudinal studies and trials are needed.

Added sugars and sugar-sweetened beverage consumption, dietary carbohydrate index and depression risk in the Seguimiento Universidad de Navarra (SUN) Project.

The association between added sugars or sugar-sweetened beverage consumption and the risk of depression, as well as the role of carbohydrate quality in depression risk, remains unclear. Among 15 546 Spanish university graduates from the Seguimiento Universidad de Navarra (SUN) prospective cohort study, diet was assessed with a validated 136-item semi-quantitative FFQ at baseline and at 10-year follow-up. Cumulative average consumption of added sugars, sweetened drinks and an overall carbohydrate quality index (CQI) were calculated. A better CQI was associated with higher whole-grain consumption and fibre intake and lower glycaemic index and consumption of solid (instead of liquid) carbohydrates. Clinical diagnoses of depression during follow-up were classified as incident cases. Multivariable time-dependent Cox regression models were used to estimate hazard ratios (HR) of depression according to consumption of added sugars, sweetened drinks and CQI. We observed 769 incident cases of depression. Participants in the highest quartile of added sugars consumption showed a significant increment in the risk of depression (HR=1·35; 95 % CI 1·09, 1·67, P=0·034), whereas those in the highest quartile of CQI (upper quartile of the CQI) showed a relative risk reduction of 30 % compared with those in the lowest quartile of the CQI (HR=0·70; 95 % CI 0·56, 0·88). No significant association between sugar-sweetened beverage consumption and depression risk was found. Higher added sugars and lower quality of carbohydrate consumption were associated with depression risk in the SUN Cohort. Further studies are necessary to confirm the reported results.

2D-to-disguised 3D materials with built-in acid sites: H+-[Al]-RUB-18.

Al3+ heteroions have been incorporated into the silicate layers of Na-RUB-18 in three different molar ratios Si/AlICP (22, 40 and 42) through a post-synthesis procedure under hydrothermal conditions. Systematic characterization (XRD, 29Si NMR, 27Al NMR and SEM) showed that these Na-[Al]-RUB-18 layered aluminosilicates are free from impurities, and the aluminum did not affect the crystallinity of the material, and also did not change its morphology. 27Al NMR showed that aluminum was incorporated in the tetrahedral position and the layered sample with molar ratio Si/AlICP = 22 has also displayed octahedral coordination. These layered aluminosilicates which consist of lamella stacking in the c direction had their interlayer space expanded by ion exchange with CTA+. The swollen samples were pillared with TEOS, as the SiO2 pillar precursor, and octylamine, as the hydrolyzing agent and co-surfactant. Pillared materials presented type IV isotherms with a BET surface area in the range of 223-323 m2 g-1 and mesoporous with 2-4 nm, while their layered precursors Na-[Al]-RUB-18 showed type II isotherms with a BET surface area in the range of 7-12 m2 g-1. Additionally, the acidity present in the layers of these pillared solids was proved by in situ ethanol dehydration monitored by FTIR.
