Due to ageing populations, there is a rapid increase in people living with dementia. A number of modifiable risk factors have been identified, including obesity, excessive alcohol consumption, diabetes mellitus, depression, physical inactivity, smoking and social isolation. The aim of this cluster-randomised controlled trial, including 1030 participants at risk of developing dementia aged 60-77, was to evaluate the effectiveness of a multidomain intervention which included optimisation of nutrition and medication, and physical, social, and cognitive activity for two years compared to standard care. There was no benefit of the intervention for the primary outcome global cognitive performance. The intervention had a positive effect on the secondary outcome health-related quality of life but did not have any significant effect on quality of life, depressive symptoms, social inclusion, activities of daily living and instrumental activities of daily living. The study period coincided with the COVID-19 pandemic. Significantly more participants than controls reported perceived COVID-19-related restrictions with regards to nutrition, whilst there was no such differences between groups for physical, cognitive or social activity. Better adherence to the nutrition and social activity components of the programme were associated with better global cognitive performance, whilst there was no association with physical and cognitive activity.
Abstract
INTRODUCTION We investigated the effectiveness of a multidomain intervention to preserve cognitive function in older adults at risk for dementia in Germany in a cluster-randomized trial. METHODS Individuals with a Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) risk score ≥ 9 aged 60 to 77 years were recruited. After randomization of their general practitioner (GP), patients received a multidomain intervention (including optimization of nutrition and medication, and physical, social, and cognitive activity) or general health advice and GP treatment as usual over 24 months. Primary outcome was global cognitive performance (composite z score, based on domain-specific neuropsychological tests). RESULTS Of 1030 participants at baseline, n = 819 completed the 24-month follow-up assessment. No differences regarding global cognitive performance (average marginal effect = 0.010, 95% confidence interval: -0.113, 0.133) were found between groups at follow-up. Perceived restrictions in intervention conduct by the COVID-19 pandemic did not impact intervention effectiveness. DISCUSSION The intervention did not improve global cognitive performance. HIGHLIGHTS Overall, no intervention effects on global cognitive performance were detected. The multidomain intervention improved health-related quality of life in the total sample. In women, the multidomain intervention reduced depressive symptoms. The intervention was completed during the COVID-19 pandemic.

Frailty and pre-frailty are associated with an increased risk of premature mortality. Factors involved in the development of frailty include physical activity, sleep and nutrition. The aim of this 6-month randomised controlled trial was to evaluate the effects of an educational programme on frailty, physical function, physical activity, sleep and nutritional status. 166 community-dwelling individuals aged 65 years or over with frailty or pre-frailty were randomised to either receive a health education programme consisting of 4 group sessions in the first month which included guidelines for physical activity, nutrition and cognitive training as well as the promotion of psychological and social wellbeing and 6 follow-up calls over 6 months or their usual healthcare (control). Compared to the control group, the intervention group had significant reductions in frailty score, exhaustion and fatigue score, increase in gait speed and improvements in various physical function tests. The intervention group also showed significant improvements in mini nutritional assessment compared to the control group although this was not associated with significant changes in anthropometric parameters. There was a significant increase in awakenings in the control group whilst this parameter did not change in the intervention group, whilst there were no changes in other sleep parameters. The authors concluded that the simplicity, affordability and effectiveness of the health education programme may contribute to healthy ageing.

Introduction
- Frailty and pre-frailty increase the risk of premature mortality but are reversible
- The aim of this study was to evaluate the effects of a health education programme on frailty status in frail or pre-frail older persons.
Methods
- Randomised controlled trial
- Participants: 166 community-dwelling individuals aged 65 years or over with frailty or pre-frailty living in Spain were enrolled, 163 completed the study (80 in intervention and 83 in control group)
- Four weekly group sessions which included guidelines for physical activity, nutrition and cognitive training as well as the promotion of psychological and social wellbeing and 6 follow-up calls over 6 months versus usual healthcare (control).
Results
- Baseline demographics: The educational group consisted of more women (p=0.001), had a younger average age (p=0.019), lower height (p=0.001) and a higher average education level (p=0.013) compared to the control group.
Effects on intervention group:
- Reductions in frailty score (p<0.05 vs baseline and change vs change in control group), with 30% of participants in the intervention group no longer being classified as frail or pre-frail in contrast to none in the control group
- Reductions in fatigue and exhaustion score (p<0.05 vs baseline and change vs change in control group)
- Increase in gait speed and improvements in various physical function tests (all p<0.05 vs baseline and change vs change in control group)
- Improvements in mini nutritional assessment (p<0.001 vs baseline and change vs change in control group)
- Improvement in sleep behaviour demonstrated by an increase in awakenings in the control group (p<0.05 vs baseline and change vs change in intervention group) whilst this parameter did not change in the intervention group.
No effects (vs control) on:
- Anthropometric parameters/unintended weight loss
- Other sleep parameters
- Physical activity expenditure and physical activity score
- Hand grip strength.
Conclusion
This affordable and simple health education programme is effective in reducing frailty in elderly and may contribute to healthy ageing.
Clinical practice applications:
- A comprehensive programme, encompassing not only nutrition, but also exercise, cognitive training and a focus on social and psychological wellbeing may be most effective in improving frailty and physical functioning
- Nutrition intervention, alongside other lifestyle interventions, may have benefits for nutritional status in older adults, even if this is not reflected in a change in anthropometric parameters, such as weight.
Considerations for future research:
- Studies with longer-term follow-up would help evaluate whether/for how long the benefits are sustained.
Abstract
INTRODUCTION The prevalence of frailty is increasing worldwide, emphasizing the importance of prioritizing healthy ageing. To address this, cost-effective and minimally supervised interventions are being sought. This study aimed to assess the impact of an educational program on frailty status, physical function, physical activity, sleep patterns, and nutritional status in community-dwelling older adults with at least 1 Fried's frailty criteria. METHODS A 6-month multicentre randomized controlled trial was conducted from March 2022 to February 2023 in 14 health centres located in Cadiz and Malaga, Spain. The educational intervention consisted of 4 group sessions and 6 follow-up phone calls spread over 6 months. The program focused on educating participants about frailty and its impact on health, providing guidelines for physical activity, healthy dietary habits, cognitive training, psychological well-being and social activities. A total of 163 participants, divided into control (n = 80) and educational groups (n = 83) were assessed before and after the intervention. RESULTS The results showed a significant group-time interaction in the physical function evaluated with a large effect on Short Physical Performance Battery score (η2p = 0.179, -0.1 [-1.2-1.0] points for control group vs. 1.0 [0.0-3.0] points for educational group, p < 0.001), and an effect on the 4-meter gait test ((η2p = 0.122, 0.5 [0.1-0.0] s for control group vs. -0.4 [-0.5- -0.3] s for educational group, p < 0.001), and the 5-repetition sit-to-stand test (η2p = 0.136, 1.0 [0.0-1.2] s for control group vs. -4.3 [-7.0- -2.3] for educational group, p < 0.001). Additionally, the use of accelerometers to assess physical activity, inactivity, and sleep patterns revealed a significant small effect in the number of awakenings at night ((η2p = 0.040, 1.1 [-0.5-3.4] awakenings for control group vs. 0.0 [-2.2-0.0] awakenings for educational group, p = 0.009). The findings also highlighted a significant medium effect regarding malnutrition risk, which was assessed using the Mini-Nutritional Assessment score (η2p = 0.088, -0.7 [-2.3-1.5] points for control group vs. 1.5 [-0.5-3.0] points for educational group, p < 0.001). DISCUSSION Thus, the 6-month educational program effectively improved physical function, sleep patterns, and nutritional status compared to usual healthcare attendance in community-dwelling older adults with frailty or pre-frailty. These findings underscore the potential of minimally supervised interventions in promoting a healthy lifestyle in this vulnerable population.

Plain language summary
Migraine is considered as an intense unilateral throbbing headache, often accompanied by nausea, vomiting, photophobia and phonophobia, which can be exacerbated by routine physical activity. It has been shown that cytokines levels are altered in migraineurs. Cytokines are inflammatory mediators that can stimulate calcitonin gene-related peptide (CGRP) [amino acid] transcription. The aim of this study was to investigate the effects of soy isoflavones supplementation on migraine headache characteristics, mental status, quality of life and CGRP concentration in adult women with migraine. This study is a double-blind, placebo-controlled clinic trial. Participants (n=88 women) were randomly assigned to one of the two groups: intervention or placebo groups (1:1). Patients in the intervention group received one tablet containing 50 mg isoflavones. Results indicate that consumption of 50 mg/day soy isoflavones supplementation for 8 weeks led to significant reduction in frequency, duration, and clinical indices of migraine and improved quality of life and CGRP levels. However, severity of migraine headache and mental status including depression, stress and anxiety were not affected by supplementation. Authors conclude that even though their findings were promising, further studies focusing on the mental status dimensions including depression, stress and anxiety are needed.
Abstract
BACKGROUND Literature suggests a relationship between estrogen levels and migraine headache pathogenesis. However, the effect of soy isoflavones on migraine characteristic remains unclear. This study aimed to investigate the effect of soy isoflavones on migraine characteristics and calcitonin gene-related peptide (CGRP) levels in women with migraine. METHODS Eighty-three participants completed a randomized double-blind controlled trial, receiving 50 mg per day soy isoflavones or placebo supplementation for 8 weeks. Migraine severity, migraine days per month, frequency and duration of attacks, mental status, quality of life and serum CGRP levels were measured at baseline and the end of the intervention. Bivariate comparison and intention-to-treat (ITT) were used for analysis. RESULTS Soy isoflavones intake resulted in a significant decrease in mean frequency (-2.36 vs -0.43, P < 0.001), duration (-2.50 vs -0.02, P < 0.001) of migraine attacks and CGRP level (-12.18 ng/l vs -8.62, P = 0.002) in compared to placebo group. Also, a significant improvement was found in quality of life (16.76 vs 2.52, P < 0.001). Although, reduction in the migraine severity and mental status did not reach a statistically significant level (P > 0.05). CONCLUSION soy isoflavones supplementation may be considered as a complementary treatment for women with migraine to improve migraine characteristics and reduce the burden of disease.

In response to the global outbreak of COVID-19, a wave of quarantine and stay-at-home mandates were issued to attenuate the rapid worldwide spread. The aim of this study was to quantify changes in habitual dietary behaviours, physical activity, sleep, sedentary behaviours, and mental health before and during the initial peak of the COVID-19 pandemic. This study is based on an anonymous survey via paid advertisements on the social media platform Facebook. A total of 7,753 completed the first COVID-19 question and were thus included in the analysis. Results indicate that: - declines in healthful eating behaviours were coincident with reductions in physical activity. These negative behaviours were characteristic of individuals reporting weight gain in response to the pandemic outbreak. - anxiety scores nearly doubled in response to the pandemic and 20% of the sample reported that symptoms were severe enough to interfere with daily routines. - home confinement led to shifts in daily work and household responsibilities which resulted in mental health declines alongside some positive and many negative changes to health behaviours. Authors conclude that with increased cases of weight gain and significant declines to mental health, COVID-19 may impact clinical practice for years to come.
Abstract
OBJECTIVE Stay-at-home orders in response to the coronavirus disease 2019 (COVID-19) pandemic have forced abrupt changes to daily routines. This study assessed lifestyle changes across different BMI classifications in response to the global pandemic. METHODS The online survey targeting adults was distributed in April 2020 and collected information on dietary behaviors, physical activity, and mental health. All questions were presented as "before" and "since" the COVID-19 pandemic. RESULTS In total, 7,753 participants were included; 32.2% of the sample were individuals with normal weight, 32.1% had overweight, and 34.0% had obesity. During the pandemic, overall scores for healthy eating increased (P < 0.001), owing to less eating out and increased cooking (P < 0.001). Sedentary leisure behaviors increased, while time spent in physical activity (absolute time and intensity adjusted) declined (P < 0.001). Anxiety scores increased 8.78 ± 0.21 during the pandemic, and the magnitude of increase was significantly greater in people with obesity (P ≤ 0.01). Weight gain was reported in 27.5% of the total sample compared with 33.4% in participants with obesity. CONCLUSIONS The COVID-19 pandemic has produced significant health effects, well beyond the virus itself. Government mandates together with fear of contracting the virus have significantly impacted lifestyle behaviors alongside declines in mental health. These deleterious impacts have disproportionally affected individuals with obesity.

After China, Italy was the first country in which the coronavirus disease 2019 (COVID-19) pandemic rapidly spread. As a consequence, a lockdown was imposed in the entire nation to reduce the spread of infections. The main aim of this study was to investigate how the negative emotions raised by the lockdown and the social features that characterised the quality of life during lockdown interacted with individual characteristics to affect the eating behaviour during the lockdown. This study is based on an anonymous online survey which was shared via social media targeting Italian residents or speakers who were 18 years of age or older. A total of 365 participants were considered for this study. Results indicate that: - increased emotional eating was significantly predicted by higher level of anxiety, depression, and partially, by Quality of Life and Quality of the Relationships. - increased binge eating was predicted by higher stress. - higher alexithymia [a broad term to describe problems with feeling emotions] scores were associated by increased emotional eating and higher body mass index scores were associated with both increased emotional eating and binge eating. - emotional eating and binge eating decreased significantly in Phase 2 compared to Phase 1 of the lockdown period. Authors conclude that future policies during lockdown should also take into consideration the emotional toll on individual well-being and should include measures of psychological support.
Abstract
Due to the spread of COVID 2019, the Italian government imposed a lockdown on the national territory. Initially, citizens were required to stay at home and not to mix with others outside of their household (Phase 1); eventually, some of these restrictions were lifted (Phase 2). To investigate the impact of lockdown on emotional and binge eating, an online survey was conducted to compare measures of self-reported physical (BMI), psychological (Alexithymia), affective (anxiety, stress, and depression) and social (income, workload) state during Phase 1 and Phase 2. Data from 365 Italian residents showed that increased emotional eating was predicted by higher depression, anxiety, quality of personal relationships, and quality of life, while the increase of bingeing was predicted by higher stress. Moreover, we showed that higher alexithymia scores were associated by increased emotional eating and higher BMI scores were associated with both increased emotional eating and binge eating. Finally, we found that from Phase 1 to Phase 2 binge and emotional eating decreased. These data provide evidence of the negative effects of isolation and lockdown on emotional wellbeing, and, relatedly, on eating behaviour.

Dietary factors and healthy eating habits play a crucial role in human health management. The global pandemic of COVID-19 has significantly changed the dietary patterns and eating habits of the people worldwide, particularly in the area affected by this pandemic. The aim of this study was to assess the knowledge of COVID-19 disease and its association with anxiety, depression, dietary habits, and physical activity during the COVID-19 lockdown. This study was a descriptive cross-sectional survey conducted in the Punjab Province of Pakistan. A total of 1956 participants took part in the study. Results indicate that: - only 7.4% of participants had good knowledge about COVID-19. - the physical activity of the participants was affected as 66.9% of the participants had a decrease in physical activity and around 40% of the participants also gained weight. - around 70% of the participants were suffering from anxiety, and 52% were depressed. Authors conclude that their findings can help formulate concrete policy-making for the Pakistani population in terms of public health prospects. Furthermore, mass-level educational programmes should be launched via print and electronic media to enhance public awareness about COVID-19 and to improve dietary behaviour of people.
Abstract
Coronavirus infection (COVID-19) has significantly increased the mortality and morbidity rates worldwide. The present study was conducted to assess the general public's awareness of COVID-19 and its association with mental health, dietary habits, and physical activity. A web-based survey was conducted to gather information about demographics, knowledge about COVID-19, dietary habits, mental health, and anthropometry among the general public of Pakistan. Descriptive statistics, chi-square test, and multiple logistic regression were used for data analysis. The majority of the participants were suffering from anxiety (71.0%) and depression (52.0%) during the COVID-19 pandemic; 32.4% of participants had poor COVID-19-related knowledge. COVID-19 lockdown reduced the physical activity of 66.9% of participants and increased weight of 38.8% of the survey participants. Demographic variables, including age, gender, ethnicity, education, employment, family type, and geographical location, were significantly associated with knowledge about COVID-19 (P < 0.05). Depression was inversely associated with COVID-19 knowledge (P < 0.05). Healthy changes in dietary habits including decreased consumption of fast foods, soft and cola drinks, fruit drinks, cooked meat (outside the home), sugar, and fats, and were associated with increased knowledge of COVID-19. Vitamin C and immunity-boosting supplement consumption were significantly associated with increased knowledge regarding COVID-19 (< 0.05). Inadequate knowledge about COVID-19 and the presence of anxiety and depression were found among most of the study participants. There is a need to conduct educational seminars to limit the health consequences resulting from COVID-19 lockdown.

Recent research has showed that the prevalence of insomnia, depressive and anxiety symptoms among Chinese middle school students was 21.90%, 43.70% and 37.40%, respectively, during the COVID-19 period. The aims of this study were: (1) to explore the prevalence of insomnia, depressive and anxiety symptoms among Chinese adolescents during the COVID-19 outbreak; (2) to investigate associations of socio-demographic factors and COVID-fear with insomnia, depressive and anxiety symptoms; (3) to investigate associations of nutrition and physical activity with insomnia, depressive and anxiety symptoms after adjusting socio-demographic factors and COVID-fear. This study included 1,794 students (males n= 56.20% and females n= 43.80%) aged 15 and 18 years. Results indicate that prevalence of insomnia, depressive and anxiety symptoms was high in the participating cohort. The highest prevalence was among female participants, left behind children and students with higher COVID-fear. Both better nutritional status, moderately and highly active physical activity levels were protective factors for depression and anxiety, while highly active physical activity level was significantly associated with lower level of insomnia symptoms. Authors conclude by emphasising on the important role of psychology counsellors in schools, health authorities and educators to carry out early psychological interventions.
Abstract
Mental health problems are common among adolescents and greatly influenced by stressful events. This study sought to assess the prevalence and correlates of insomnia, depressive and anxiety symptoms among Chinese adolescents during the COVID-19. METHOD Cross-sectional study (N = 1,794 adolescents, mean age = 15.26) was conducted in May 2020. An online survey was used to collect socio-demographic data, COVID-related fear (COVID-fear), nutrition, physical activity (PA) level and the symptoms of insomnia, depression and anxiety. RESULTS The prevalence of insomnia, depressive and anxiety symptoms was 37.80%, 48.20% and 36.70%, respectively, among Chinese adolescents during the pandemic. Generalized linear models revealed that female, left behind children, and students with greater COVID-fear tended to report symptoms of insomnia, depression and anxiety concurrently. After adjusting for socio-demographic factors and COVID-fear, better nutritional status and moderately active PA were both associated with lower levels of depressive and anxiety symptoms, while highly active PA was associated with lower levels of insomnia, depressive and anxiety symptoms. CONCLUSIONS These findings suggest that more attention should be paid to psychological health among adolescents while combating COVID-19. To promote adolescents' mental health, educators should help adolescents develop a healthy lifestyle with balanced diet and regular exercise. Los problemas de salud mental son comunes en adolescentes y están influenciados por eventos estresantes. Se evaluó prevalencia y correlatos de síntomas de insomnio, depresión y ansiedad en adolescentes chinos durante el COVID-19. Método: En mayo de 2020 se realizó un estudio transversal (N = 1.794 adolescentes, edad media = 15,26) mediante una encuesta en línea para recopilar datos sociodemográficos, miedo relacionado con COVID-19, nutrición, actividad física (AF) y síntomas de insomnio, depresión y ansiedad. Resultados: La prevalencia de síntomas de insomnio, depresión y ansiedad fue del 37,80%, 48,20% y 36,70%, respectivamente. Modelos lineales generalizados revelaron que mujeres, niños abandonados y estudiantes con más miedo al COVID-19 tendían a informar síntomas de insomnio, depresión y ansiedad simultaneamente. Después de ajustar los factores sociodemográficos y el miedo al COVID-19, mejor estado nutricional y AF moderadamente activa se asociaron con niveles más bajos de síntomas de depresión y ansiedad, mientras que AF muy activa se asoció con niveles más bajos de insomnio, síntomas depresivos y de ansiedad. Conclusiones: Se debe prestar más atención a la salud psicológica de los adolescentes mientras se combate el COVID-19. Para promover su salud mental, los educadores deben ayudarles a desarrollar un estilo de vida saludable con una dieta equilibrada y ejercicio regular.

In recent years, the multidomain strategy, an approach characterised by the combination of several lifestyle interventions, have received increasing attention. The main aim of this study was to describe the feasibility and acceptability of a 6-month randomised controlled trial (RCT) of a web-based multidomain lifestyle training intervention for community-dwelling older people with spontaneous memory complaint. A secondary objective was to test the effects of the intervention on both function and lifestyle-related outcomes. This study (eMIND) is a 6-month pilot, parallel-arm, RCT of a multidomain lifestyle intervention composed of cognitive training, exercise training, and nutritional advice, among community-dwelling older adults. Participants were randomly assigned to one of the two arms: multidomain intervention group (MIG) or control group (CG). Results show that study procedures were well-accepted, but expectations regarding participant’s adherence to the intervention were not met, particularly for exercise. Moreover, compared to the CG, participants of the MIG have improved their health-related quality of life at the end of the 6-month intervention. Authors conclude that implementing a web-based multidomain lifestyle-training platform accessible to a large number of older people could have a major positive impact in a public health perspective.
Abstract
UNLABELLED Importance/Objective: To describe the feasibility and acceptability of a 6-month web-based multidomain lifestyle training intervention for community-dwelling older people and to test the effects of the intervention on both function- and lifestyle-related outcomes. DESIGN 6-month, parallel-group, randomized controlled trial (RCT). SETTING Toulouse area, South-West, France. PARTICIPANTS Community-dwelling men and women, ≥ 65 years-old, presenting subjective memory complaint, without dementia. INTERVENTION The web-based multidomain intervention group (MIG) received a tablet to access the multidomain platform and a wrist-worn accelerometer measuring step counts; the control group (CG) received only the wrist-worn accelerometer. The multidomain platform was composed of nutritional advices, personalized exercise training, and cognitive training. Main outcomes and measures: Feasibility, defined as the proportion of people connecting to ≥75% of the prescribed sessions, and acceptability, investigated through content analysis from recorded semi-structured interviews. Secondary outcomes included clinical (eg, cognitive function, mobility, health-related quality of life (HRQOL)) and lifestyle (eg, step count, food intake) measurements. RESULTS Among the 120 subjects (74.2 ±5.6 years-old; 57.5% women), 109 completed the study (n=54, MIG; n=55, CG). 58 MIG subjects connected to the multidomain platform at least once; among them, adherers of ≥75% of sessions varied across multidomain components: 37 people (63.8% of 58 participants) for cognitive training, 35 (60.3%) for nutrition, and three (5.2%) for exercise; these three persons adhered to all multidomain components. Participants considered study procedures and multidomain content in a positive way; the most cited weaknesses were related to exercise: too easy, repetitive, and slow progression. Compared to controls, the intervention had a positive effect on HRQOL; no significant effects were observed across the other clinical and lifestyle outcomes. CONCLUSIONS AND RELEVANCE Providing multidomain lifestyle training through a web-platform is feasible and well-accepted, but the training should be challenging enough and adequately progress according to participants' capabilities to increase adherence. Recommendations for a larger on-line multidomain lifestyle training RCT are provided.

Synbiotic, a mixture of prebiotics and probiotics, is known to improve neurotransmitter interactions, immune, inflammatory, and stress responses by modulating the gut microbial composition. It is also believed that physical activity plays an important role in the modulation of immune function and stress response. The purpose of this triple-blinded, randomized, placebo-controlled pilot study was to evaluate the health benefits of symbiotic intervention in fourteen sedentary students and thirteen soccer players, especially in terms of improving immunophysiological and metabolic parameters. The 300mg of symbiotic intervention contained Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, Bifidobacterium longum ES1(109 colony-forming unit), and fructooligosaccharides (200 mg) plus 1.5 mg of zinc, 8.25 µg of selenium, 0.75 µg of vitamin, and maltodextrin. Following a one-month intervention with synbiotic formulation, soccer players showed improvements in anxiety, sleep quality and stress, a slight reduction in proinflammatory cytokine IL-1β, an exercise-induced significant increase in dopamine and a slight elevation of corticotropin-releasing hormone. For confirmation of results of this pilot study and to assess more significant effects of symbiotic intervention in athletes as well as in the general population, longer-term robust studies are required. The findings of this study can help healthcare professionals understand the extensive health benefits of synbiotic intervention and its relationship to physical activity.
Abstract
The main objective of this research was to carry out an experimental study, triple-blind, on the possible immunophysiological effects of a nutritional supplement (synbiotic, Gasteel Plus®, Heel España S.A.U.), containing a mixture of probiotic strains, such as Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, and Bifidobacterium longum ES1, as well as the prebiotic fructooligosaccharides, on both professional athletes and sedentary people. The effects on some inflammatory/immune (IL-1β, IL-10, and immunoglobulin A) and stress (epinephrine, norepinephrine, dopamine, serotonin, corticotropin-releasing hormone (CRH), Adrenocorticotropic hormone (ACTH), and cortisol) biomarkers were evaluated, determined by flow cytometer and ELISA. The effects on metabolic profile and physical activity, as well as on various parameters that could affect physical and mental health, were also evaluated via the use of accelerometry and validated questionnaires. The participants were professional soccer players in the Second Division B of the Spanish League and sedentary students of the same sex and age range. Both study groups were randomly divided into two groups: a control group-administered with placebo, and an experimental group-administered with the synbiotic. Each participant was evaluated at baseline, as well as after the intervention, which lasted one month. Only in the athlete group did the synbiotic intervention clearly improve objective physical activity and sleep quality, as well as perceived general health, stress, and anxiety levels. Furthermore, the synbiotic induced an immunophysiological bioregulatory effect, depending on the basal situation of each experimental group, particularly in the systemic levels of IL-1β (increased significantly only in the sedentary group), CRH (decreased significantly only in the sedentary group), and dopamine (increased significantly only in the athlete group). There were no significant differences between groups in the levels of immunoglobulin A or in the metabolic profile as a result of the intervention. It is concluded that synbiotic nutritional supplements can improve anxiety, stress, and sleep quality, particularly in sportspeople, which appears to be linked to an improved immuno-neuroendocrine response in which IL-1β, CRH, and dopamine are clearly involved.

Plain language summary
Certain inborn errors of metabolism have been linked to several conditions with intellectual disability (ID). Treating these preventable or treatable forms of ID require the support of experts in nutrition and medicine. However, nutritional measures and diet must be adjusted to the different syndromes and their inherent implications, which requires knowledge of ID in general, and of specific diagnosis groups in particular. In addition, challenging behaviour, lower cognitive functions, and capacity in daily-life activities translate into nutritional problems such as shopping, cooking and eating patterns, including snacking, that require systematic professional support. This study shows that the development of adapted mobile phone programs and apps will be of great value in interventions, educational studies and for persons with ID to help them manage their daily chores and their diet, particularly those with moderate and light ID. Addressing the multifaceted challenges of nutrition and health in persons with ID requires more research and increased priority from funding agencies, along with increased visibility and knowledge of the various forms of ID in general.
Abstract
Intellectual disability (ID) is a condition that affects approximately 1% of the population (Maulik et al, 2011). The numbers may differ across nations, owing to different systems and diagnosis entries or lack of such, but usually range between 0.6 and 3% (Stromme & Valvatne, 1998). Persons with ID are a heterogeneous group with different diagnoses and different levels of intellectual ability. These range from profound (IQ < 20) and serious ID (IQ 20-34) to moderate (IQ 35-49) and light ID (IQ 50-69); this roughly translates into the intellectual capacity of children between 3-12 years of age. More than 75% of persons with ID have the mild form and their intellectual capacity and potential may be underestimated in some cases if IQ is the only diagnostic criteria. However, the range in itself is an important factor to take into account when addressing nutrition and health issues. It is further important to recognize that ID is also a feature of several rare disorders, and many disorders not yet identified, adding to the complexity of this group.
