Effect of physical exercise in people with hypothyroidism: systematic review and meta-analysis.

This study aimed to systematically revise the available evidence on the effects of physical exercise training programmes on people with hypothyroidism. Comparative studies were searched in six electronic databases until April 2023. The Physiotherapy Evidence Database and the Methodological Index for Non-Randomized Studies were used to determine the methodological quality of the randomized controlled trials and comparative studies respectively. A total of 10 studies were found showing a low to moderate methodological quality. Most of them were performed in women with subclinical hypothyroidism. Exercise seemed to be safe, with aerobic and resistance training leading to improvements in outcomes related to physical and mental health. The performed meta-analysis with data from 120 participants indicated that exercise showed a non-significant trend towards reducing thyroid-stimulating hormone levels (Hedges'g -0.96; 95% CI -2.71; 0.79, p = 0.160; I2 = 92%). When the analysis was performed by comparing the experimental, and control groups with data from 180 participants the results remained non-significant (SMD -1.09; CI 95% -2.88; 0.70, p = 0.23; I2 = 95%). Similar findings were obtained when pooling data for FT3 and FT4 levels. Exercise does not have a significant impact on thyroid function, although its practice can lead to secondary outcomes related to physical and mental health.

Relationships between RPE-derived internal training load parameters and GPS-based external training load variables in elite young soccer players.

This study aimed to identify the GPS-based external training load variables that influence the internal training loads (RPE-derived parameters: RPE and session RPE - sRPE), and generate a model to predict GPS-based external load variables from RPE and perceived wellness values. Training load data for 21 elite young players were collected over 72 training sessions and 23 matches from the same competitive season, and 564 observations (training sessions, 462; matches, 102) were analysed. Considering all observations (training sessions and matches), significant moderate and large correlations (p < 0.01) were detected between RPE values and EL measures. The correlation between the GPS outcomes with both the RPE and sRPE values was higher during training sessions than during matches. Moreover, increased RPE and perceived wellness measures had a significant positive effect on external load variables (p < 0.001). The present work provides preliminary evidence of the utility of the RPE and sRPE method to quantify the training loads in young soccer players since most of the GPS-based EL indicators were moderate to highly correlated with the RPE-derived parameters. Additionally, EL variables may be estimated when combining perceived IL and subjective wellness indicators in young soccer players.

Field-based tests for assessing fitness in referees: A systematic review.

This systematic review was aimed at identifying the psychometric properties of field-based tests for assessing physical fitness in soccer referees. Electronic databases were searched up to May 2020 for studies that informed about the reliability and/or validity of at least one field-based physical fitness test for soccer referees. A total of 13 studies analysed the psychometric properties of the field-based physical fitness tests proposed by the Fédération Internationale de Football Association (FIFA) (aerobic endurance, n = 8; anaerobic endurance, n = 3; and speed, n = 8), while seven investigations focused on field-based physical fitness tests specifically designed for assessing aerobic endurance (n = 1) or change of direction (COD) (n = 6). According to the observed reliability and validity values, the Assistant Referee Intermittent Endurance test (ARIET), the 50-m sprint test and the Modified Agility test (MAT) seem, respectively, the best available options for assessing aerobic endurance, speed, and COD in soccer referees. Future investigations should consider the lack of research focusing on assistant and female referees. Further studies on the psychometric properties of anaerobic endurance and short distance speed tests are also needed.

Adherence to recommended intake of pulses and related factors in university students in the UniHcos project.

Pulses such as peas, beans or lentils are one of the most complete foods at the nutritional level; however, they are one of the most often neglected foods in the diets of university students. Entrance to university translates into a major lifestyle change for many young people, and the habits acquired or cemented at this time will remain into adulthood. The objective of this study is to analyse the association between personal/sociodemographic factors, dietary intake of other food groups and the consumption of pulses in first-year university students. This cross-sectional study is part of the UniHcos project, a multicentre study of multipurpose prospective cohorts in eleven Spanish universities. Data from 9862 university students were collected through an online self-questionnaire completed by all students who met the selection criteria and agreed to participate in the project during the 2011-2018 academic years. Of students, 75·8 % presented an inadequate (≤2 times/week) consumption of pulses. Living outside the family home in either a student residence (OR 0·76; 95 % CI 0·69, 0·84) or rental (OR 0·81; 95 % CI 0·70, 0·95) decreased the compliance with recommendations on the consumption of pulses. Low consumption of pulses is seemingly not restricted to a specific profile or dietary pattern among university students, and no specific focus group for intervention can be identified. Policies promoting the consumption of pulses among the university population as a whole are necessary to increase compliance rates with the dietary recommendations.

The Efficacy of Re-Warm-Up Practices during Half-Time: A Systematic Review.

Background and Objectives: The passive nature of rest breaks in sport could reduce athletes' performance and even increase their risk of injury. Re-warm-up activities could help avoid these problems, but there is a lack of research on their efficacy. This systematic review aimed at analyzing the results of those randomized controlled trials (RCTs) that provided information on the effects of re-warm-up strategies. Materials and Methods: Four electronic databases (Web of Science, Scopus, PubMed, and SPORTDiscus) were searched from their inception to January 2021, for RCTs on the effects of re-warm-up activities on sports performance. Interventions had to be implemented just after an exercise period or sports competition. Studies that proposed activities that were difficult to replicate in the sport context or performed in a hot environment were excluded. Data were synthesized following PRISMA guidelines, while the risk of bias was assessed following the recommendations of the Cochrane Collaboration. Results: A total of 14 studies (178 participants) reporting data on acute or short-term effects were analyzed. The main outcomes were grouped into four broad areas: physiological measures, conditional abilities, perceptual skills, and sport efficiency measures. The results obtained indicated that passive rest decreases physiological function in athletes, while re-warm-up activities could help to improve athletes' conditional abilities and sporting efficiency, despite showing higher fatigue levels in comparison with passive rest. The re-warm-up exercise showed to be more effective than passive rest to improve match activities and passing ability. Conclusions: Performing re-warm-up activities is a valuable strategy to avoid reducing sports performance during prolonged breaks. However, given that the methodological quality of the studies was not high, these relationships need to be further explored in official or simulated competitions.

Influence of the Box Dimensions on the Reliability and Validity of the Sit and Reach in Preschoolers.

Ayán Pérez, C, Martínez de Quel, Ó, Álvarez Pérez, S, and González Baamonde, S. Influence of the box dimensions on the reliability and validity of the sit and reach in preschoolers. J Strength Cond Res 34(9): 2683-2692, 2020-This study aimed at analyzing the reliability and validity of the sit and reach (SR) test, when it was performed with a standard SR (SSR) or an adapted SR (ASR) box in preschoolers. To accomplish this, both tests were administered 3 times (familiarization, test, and retest) to a group of 148 children (mean age, 4.99 ± 0.94 years; 49.3% girls), with a week interval between each assessment. The obtained results in each test were compared with those obtained in the passive straight leg raise (PSLR) test with the aim of identifying their construct validity. The internal consistency was found to be between good and excellent for the SSR (α: 0.83-0.92) and excellent for the ASR (α: 0.92-0.96). The SSR showed a good and a fair reliability (intraclass correlation coefficient [ICC], 0.71-0.86), whereas the ASR showed an excellent reliability (ICC, 0.90-0.94) except for the 3-year-old children group (ICC, 0.84). Absolute reliability was excellent for the ASR, whereas the SSR yielded higher SEM and minimum detectable change percentage values. Regarding the criterion-related validity, statistically significant fair correlations were observed between both SR tests and the PSLR test. The ASR yielded higher levels of statistical significance as well as greater correlation coefficients than the SSR. This finding indicates that when it comes to assess flexibility through a low cost and easy-to-implement lineal test in preschoolers, it is advisable to use the SR with a box of reduced dimensions.

Validity and reliability of 2 upper-body strength tests for preschool children.

The "bent knee push-up" and the "timed dipping" are 2 upper-body strength assessment tests whose simplicity and ease of use make them suitable to be applied to preschool children. Nevertheless, their psychometric properties have not been properly studied for this age group. This study aimed to fill this gap. To accomplish this, both tests were administered 3 times (familiarization, test, and retest) to a group of 120 children (mean age, 48.60 ± 9.94 months; body mass index, 17.05 ± 2.04 kg·m; 50% girls), with a week interval between each assessment. The obtained results in each test were compared with those obtained in the "handheld dynamometry" (the criterion measure) with the aim of identifying their construct validity. The reliability of the tests was analyzed by comparing the obtained results during the second (test) and the third (retest) time that each 1 was carried out. Intraclass correlation coefficients (ICCs) were used to examine reliability, and Pearson's correlation coefficients were used to examine validity. The bent knee push-up showed a moderate reliability for 3-year-old children (ICC, 0.690; 95% confidence interval [95% CI], 0.379-0.845) and high for those aged 4 years (ICC, 0.848; 95% CI, 0.715-0.919) and 5 (ICC, 0.702; 95% CI, 0.441-0.841). Similar results were obtained for the timed dipping, in children aged 3 years (ICC, 0.522; 95% CI, 0.422-0.761), 4 years (ICC, 0.766; 95% CI, 0.560-0.875), and 5 years (ICC, 0.828; 95% CI, 0.677-0.908). Both tests showed a good construct validity, with the exception of the timed dipping in 3-year-old children (r = 0.200; p = 0.256). The results in this study suggest that the bent knee push-up and the timed dipping show psychometric properties that make them suitable to be used in research carried out with preschoolers.

Associations between Agility, the Relative Age Effect, Siblings, and Digit Ratio (D2:D4) in Children and Adolescents.

BACKGROUND: This study aims to analyze the influence of relative age effects, siblings, and digit ratio on the agility of children and adolescents. METHODS: The study included 283 children (9.54 ± 1.36 years) and 296 adolescents (14.68 ± 1.36 years) from four different schools. The analyzed variables included anthropometric data, the presence of siblings, relative age effect, and results from the 10 × 5 m shuttle run test. RESULTS: The findings indicated no significant association between agility and either the 2D:4D ratio or the relative age effect in both children and adolescents (p > 0.05). Additionally, having siblings did not have a notable impact on agility. Multiple regression analysis confirmed that relative age did not influence this lack of association (quarter of birth: p = 0.345, ß = 0.039; siblings: p = 0.100, ß = -0.069). However, boys showed higher performance than girls in the 10 × 5 m shuttle run test, and higher body mass index was related to lower agility. CONCLUSIONS: These findings contribute to existing knowledge on the relative effects of age and provide valuable information for physical education teachers on the influence of the 2D:4D ratio and the presence of siblings on the physical fitness of children and adolescents.

The efficacy of Pilates method in patients with hypertension: systematic review and meta-analysis.

This study aimed to systematically review the available evidence on the effects of Pilates training programs on blood pressure in hypertensive patients. Randomized clinical trials and comparative studies were searched in four electronic databases until September 2023 (updated December 2023). The methodological quality of included studies was assessed using the Physiotherapy Evidence Database and Methodological Index for Non-Randomized Studies scales. A total of 4 randomized clinical trials and 7 comparative studies were included, showing a low (n = 1), hight (n = 6), and good (n = 4) methodological quality. Data synthesis indicated that participants who performed Pilates program obtained significantly reduces on systolic blood pressure and diastolic blood pressure, of -4.76 mmHg (95% CI: -6.55 to -2.97, p < 0.001) and -3.43 mmHg (95% CI: -4.37 to -2.49, p < 0.001), respectively, in comparison with those included in the comparison groups. When the analysis was performed by comparing hypertensive, and normotensive patients, the results remained non-significant for blood pressure (systolic blood pressure: 0.96 mmHg (95% CI: -2.85 to 4.77, P = 0.49); diastolic blood pressure: 1.18 mmHg (95% CI: -1.23 to 3.58, P = 0.34); mean blood pressure: 1.73 mmHg (95% CI: -1.96 to 5.42, P = 0.36). Evidence suggests Pilates is safe for hypertensive patients and can be part of their rehabilitation, but it may not necessarily offer superior results or improve exercise adherence compared to other modalities.

Influence of Body Mass Index, Physical Fitness, and Physical Activity on Energy Expenditure during Recess.

This study aims to investigate the potential relationship between energy expenditure, physical fitness level, physical activity, and body mass index among children taking part in a 30 min school recess. A total of 259 participants from three schools were included in this study. Data on energy expenditure during recess, age, gender, anthropometric measurements, global physical fitness, and physical activity index were recorded. The evaluation sessions occurred twice a week on alternate days over two weeks. A significant gender difference was observed in energy expenditure during recess, favoring boys (p < 0.01). The participants classified as very active exhibited significantly higher scores compared to those categorized as sedentary and moderately active, respectively (p < 0.01), with a poor but significant correlation (rho: 0.208; p < 0.001). There were significant differences between energy expenditure and cardiorespiratory fitness and energy expenditure and global physical fitness (p < 0.01) with fair (rho: 0.289; p < 0.001) and poor (rho: 0.196, p = 0.001) correlation, respectively. In contrast, there were no significant differences by body mass index categories (p = 0.571). These results suggest that gender, physical activity index, and global physical fitness were found to influence energy expenditure during a 30 min recess. However, no significant relationships were found with the body mass index.

Training profile, sporting habits and injury characteristics of Spanish obstacle course races participants: cross-sectional study.

OBJECTIVES: This study aimed to provide information on the training profile and characteristics of injuries sustained by obstacle course racing competitors. METHODS: This research is a nationwide cross-sectional, self-administered online survey conducted in 2023. RESULTS: We analyzed the data collected from 201 obstacle course racing participants (mean age: 33.8 ± 7.1 years; 60.7% men). On average, athletes had 2.9 ± 2.4 years of obstacle course racing experience and participated in approximately four races in the previous year. Most of these races covered distances of 5-10 km (65.2%). Among the participants, 28.4% reported injuries, with the upper extremities being the most frequently affected. Approximately 19% of these injuries required medical supervision, and 2% led to hospitalization. CONCLUSION: Injury risk in obstacle course racing participants was associated with participation in a higher number of obstacle course racing competitions, reduced time between these competitions and having performed specific obstacle training.

Benefits of Table Tennis for Children and Adolescents: A Narrative Review.

This study aims to review the scientific evidence regarding the effects of table tennis practice on children and adolescents. Studies were searched in three electronic databases (PubMed, Scopus, and SportDiscus) from their inception up to May 2024. The methodological quality of the included studies was assessed using the 10-point Physiotherapy Evidence Database (PEDro) and Methodological Index for Non-Randomized Studies (MINORS). A total of twelve studies were examined, with interventions involving children with intellectual disabilities, ADHD, DCD, ASD, and typically developing children. A variety of training programs were assessed over durations ranging from 6 weeks to 1 year in the studies included. Table tennis was shown to positively impact various domains, including executive function, motor skills, visual perception, graphomotor function, gross motor skills, coordination capacity, behavioral inhibition, and social behavior. Nonetheless, it is imperative to expand the number of studies on children and adolescents with diverse conditions to more comprehensively evaluate the benefits of table tennis for each specific condition.

Exploring research on competitive Para-cyclists and its related factors: A scoping review.

ABSTRACT: This scoping review aimed to explore the characteristics and performance factors of competitive Para-cyclists. A systematic search for studies on competitive Para-cycling on WOS, PubMed, SPORTDiscus and Scopus was performed until December 2023. Five methodological phases were followed: (i) identifying the research question, (ii) identifying relevant studies, (iii) study selection, (iv) charting the data, and (v) collating, summarizing, and reporting the results. A systematic search across multiple databases was performed until March 2024. Five methodological phases were employed: identifying the research question, relevant studies, study selection, charting data, and summarizing results. A total of 36 relevant studies were selected. Three main research themes emerged: Sport performance (n = 15), Biomechanics (n = 12), and Physical and mental health (n = 9). Despite progress, gaps were identified, particularly in physiological response to exercise, fitness, and training. Biomechanics studies focused on prosthetic use and aerodynamics, mostly involving lower-limb amputees and simulated tandem competition. Injury risk in Para-cycling appeared comparable to able-bodied cycling, but comprehensive studies considering confounding variables are needed. Overall, while research on Para-cycling is growing, more studies with larger and diverse samples across all sport classes are essential to advance scientific understanding in this field.

Analysis of the Energy Expenditure of Sports School Activities in Children.

(1) Background: This study explores the potential energy expenditure associated with participation in after-school sports activities among primary school children. (2) Methods: The study involved 129 children age (11.35 ± 0.55 years) recruited from eight different public after-school sport programs. (3) Results: Data analyses revealed significant differences between the eight sports in total calories per session, calories per minute, and METs (p < 0.05). All sports showed higher energy expenditure compared to chess (p < 0.05), with soccer and rugby exhibiting the highest energy expenditure per session. Team sports showed elevated energy consumption per session (p < 0.01, r > 0.30), calories per minute (p = 0.01, r > 0.40), and METs (p < 0.01, r > 0.40) in comparison with individual sports. (4) Conclusions: These findings enhance our understanding of the energy expenditure observed in primary school children following various after-school sports activities. The results indicate that team sports, in particular, are pivotal in elevating physical activity levels, thereby playing an essential role in fostering healthier lifestyles among children.

Changes in alcohol consumption during the COVID-19 among first-year university students in Spain, considering the risk of problematic use - UniHcos project.

The aim of this study was to evaluate the possible impact of the COVID-19 pandemic on prevalence rates and self-reported changes in patterns of alcohol use among first-year university students in Spain, considering the risk of problematic alcohol use. A serial cross-sectional study based on the uniHcos project was carried out. Data from 10 518 first-year university students (73.3% female, mean age 19 (SD = 1.6)) collected between 2012 and 2022 were analysed. The evolution of the pooled prevalence rates during the time series was analysed and the risk of problematic alcohol consumption was assessed using the AUDIT. Also, self-reported changes in alcohol use patterns during the pandemic were assessed. According to the results, during the COVID-19 pandemic, the prevalence of alcohol use in the past 30-days was reduced (76.3% in 2019 vs. 63.7% in COVID-19) increasing again in the New Normal period. Thus, a similar pattern in the practice of binge drinking was observed. Regarding the AUDIT score, 21.7% (95%CI 20.9, 22.6) of the students had harmful alcohol consumption, with a higher proportion among males. In the multivariable logistic models, a higher AUDIT score was significantly associated (p-value < 0.001) with being male and living with roommates. According to self-reported changes in consumption patterns during the COVID-19 pandemic, a higher proportion of participants with harmful use reported an increase in alcohol consumption compared to those at low-risk (43% vs 19%). Finally, despite the overall reduction in drinking prevalence during COVID-19, changes were not equal for all students and depended on their previous level of problematic drinking, highlighting that this should be considered in the development of strategies against alcohol use in this population.

Immediate effect of the use of toe separators on dynamic balance and ankle range of motion: a pilot study.

BACKGROUND AND OBJECTIVES: Injuries involving ankle stability and range of motion are among the most frequent in athletes and in the general population. In response, this study aimed to assess the immediate effects of toe separators on dynamic stability and ankle range of motion in healthy young individuals. METHODS: Among the 68 eligible participants, 50 healthy and active subjects completed all trials. The impact of the intervention was evaluated using the Weight Bearing Lunge Test and Y-Test. The control condition performed the tests without toe separators, while the experimental condition performed the tests with toe separators. All participants performed both conditions with a wash-out period of at least 7 days between trials. RESULTS: Statistical analysis revealed no significant differences in dynamic balance (p > 0.05) and range of motion (p > 0.05) between the two conditions. Additionally, no asymmetries were detected between the lower limbs in both tests (p > 0.05). CONCLUSIONS: The results of this pilot study indicate that using toe separators does not have an immediate effect on ankle range of motion and dynamic balance in young, healthy individuals. Future research should consider evaluating intervention programs of longer duration and exploring different populations.

Aquatic exercise for people with intellectual disabilities: findings from a systematic review.

Background: There is a need for promoting exercise practice among people with intellectual disabilities (ID). Aquatic exercise (AE) could be a viable option in this regard. Objective: To identify and critically analyze the best available evidence concerning the effects of AE in the physical and mental health of people with ID. Methods: A systematic review of randomized controlled trials (RCTs) and comparative studies was performed after searching within several databases up to March 2021. Results: A total of 4 RCTs and 3 comparative studies were found. Their methodological quality ranged from high to low. Aquatic interventions had positive effects on cardiorespiratory, muscular fitness and balance. Mixed effects were seen on parameters related to obesity and cognition. Scant information regarding feasibility and intervention fidelity was provided. In general, interventions details were not discussed in deep. Conclusion: Preliminary evidence shows that aquatic exercise can be prescribed to people with ID in order to improve their physical health. The impact of aquatic exercise on motor skills, cognitive function and mental health remains unclear. Further research on this topic should provide a detailed description of the interventions carried out, including information on the feasibility and intervention fidelity.

[Influence of exercise in the body image of preadolescents and adolescents: importance of the index of corporal mass as a factor of confusion]. / Influencia de la actividad en la imagen corporal en preadolescentes y adolescentes: importancia del índice de masa corporal como factor de confusión.

Introduction: Introduction: adolescents are the group most vulnerable to distortions in the perception of their image. This often leads to body dissatisfaction that can negatively affect their self-esteem. The practice of physical activity (PA) could help solve this problem. Objectives: to analyze the influence that the amount of PA performed has on the self-perception of body image in the pre and adolescent population while taking into account confounding factors that could affect this relationship. Methods: a cross-sectional study of 822 participants aged 9 to 16 years was conducted. The prevalence of PA, their body mass index (BMI), and their objective and perceived physical condition (PC) were determined. The Stunkard pictogram was used to determine the degree of body dissatisfaction. Results: a generalized satisfaction with own body image was found regardless of age and sex. Low-magnitude significant associations were found between perceived body image and the amount of PA, perceived PC, and objective PC. PA did not influence body satisfaction when adjusted for BMI, which was the variable that presented the highest correlations with self-perception (r = 0.713) and self-satisfaction (r = 0.576). Conclusions: a generalized satisfaction with one's own body image was identified in the pre and adolescent population under study. The amount of PA was not shown to be a variable with great influence on self-perception and body satisfaction, contrary to BMI.

Introducción: Introducción: los adolescentes son el grupo más vulnerable frente a las distorsiones en la percepción de la imagen. Ello les conduce frecuentemente a una insatisfacción corporal que puede afectar negativamente a su autoestima. La práctica de actividad física (AF) podría ayudar a solventar este problema. Objetivos: analizar la influencia que la cantidad de AF realizada tiene sobre la autopercepción de la imagen corporal en población pre y adolescente, teniendo en cuenta factores de confusión que pudieran afectar a esta relación. Métodos: estudio transversal con 822 participantes de entre 9 y 16 años. Se determinó la prevalencia de AF, su índice de masa corporal (IMC) y su condición física (CF) objetiva y percibida. Se empleó el pictograma de Stunkard para determinar el grado de insatisfacción corporal. Resultados: se determinó que existe una satisfacción generalizada con la propia imagen corporal con independencia de la edad y el sexo. Se encontraron asociaciones significativas de baja magnitud entre la imagen corporal percibida y la cantidad de AF, la CF percibida y la CF objetiva. La AF no influyó en la satisfacción corporal cuando se ajustó en base al IMC, que fue la variable que presentó correlaciones más elevadas con la autopercepción (r = 0,713) y la propia satisfacción (r = 0,576). Conclusiones: se determinó que existe una satisfacción generalizada con la propia imagen corporal en la población pre y adolescente objeto de estudio. La cantidad de AF no se mostró como una variable de gran influencia sobre la autopercepción y la satisfacción corporal, al contrario que el IMC.

Excess Weight in Relation to Lifestyle Habits in Spanish First-Year University Students: Differences between Pre- and Post-COVID-19-A Serial Cross-Sectional Study Based on uniHcos Project.

The objective of this research was to study the relationship between the body weight and diet, physical activity, and other habits among freshmen students by sex, and to determine whether these habits have changed during the post-era of the COVID-19 pandemic. A serial cross-sectional study with data from 11 Spanish universities was carried out. In total, 10,096 first-year university students (73.2% female, mean age = 19.0 ± 1.5 years) completed an online self-administered questionnaire between 2012 and 2022. For some analyses, questionnaires were categorized by the year in which the survey was filled out as Before COVID-19, Lockdown, and New Normal. In total, 72.9% of participants were within the normal weight range, and 17.7% of men and 11.8% of women were overweight (p < 0.001). The students who did not meet the WHO criteria of physical activity, spent more than 7 h per day sitting, and skipped breakfast had a higher prevalence of obesity (p < 0.05). According to the period of study, the prevalence of overweight/obesity Before COVID-19 was 16.1% (95% CI: 15.4-16.9%), while in Lockdown the prevalence was significantly higher (20.2, 95% CI: 17.1-23.8) and in New Normal it was 18.9% (CI: 15.7-22.5). Moreover, the study suggests that during the Lockdown period, there was a reduction in the practice of physical activity and an increase in the prevalence of a healthy diet. For all these, it is necessary to propose public health interventions that improve the lifestyles of university students.

Prevalence of Depression and Fish Consumption among First Year Spanish University Students: UniHcos Project.

The World Health Organization estimates that one fifth of university students have experienced major depressive disorder at some point in their lives. Nutrition may be one of the modifiable factors that influence the development of depression. Specifically, low omega-3 fatty acid and vitamin D levels, both nutrients found in high quantities in fish, have been linked to depressive disorders. The main objective of this study was to evaluate the prevalence of depression among young Spanish university students, in addition to the pattern of fish consumption among students and the possible relationship between fish consumption and the presence of depression. Data were collected retrospectively from a nationally representative sample of 11,485 Spanish university students aged 18 years or older in 11 Spanish universities, from 2012 to 2022. The respondents were analyzed according to frequency of consumption and compliance with weekly recommendations for fish intake and the presence of depression. Regression models were also performed to determine students' odds of depression as a function of compliance with recommendations according to selected sociodemographic variables. The prevalence of depression was 10.5%; it was more prevalent in women, older students and in those with both high and low BMIs. In addition, it was also more prevalent in those that lived outside the family home, with roommates and those who were employed. Sixty-seven percent of the students met the fish intake recommendations. The most common frequency of fish consumption was 1-2 times/week (44.2%), and the least frequent was 2.3% daily fish consumption. Students from northern universities were more likely to consume fish (68.4%) than those from southern universities (66.4%). Non-consumption of fish was found to increase the risk of depression (ORa = 1.45 (1.28-1.64); AF = 31.0% (21.9-39.0)), but it was the student's own conditions that had the greatest influence on the development of the disorder. In summary, a lower consumption of fish seems to be associated with a higher incidence of depression in Spanish university students; however, other social factors of the student may influence the development of the disorder, and all of this should be taken into account for the development of prevention strategies.
