Unipolar depression is a prevalent and disabling condition that negatively influences quality of life. Patients with depression are more vulnerable to have a poorer health-related quality of life (HRQoL). The aim of this study was to assess the effect of 2-year intervention with Mediterranean Diet enriched with extra virgin olive oil on HRQoL. This study is a multicentre, randomised, controlled, single-blind trial. The study included 52 men and 144 women aged between 18 and 86 years who had suffered at least one depression episode and who were in a stage of clinical remission. The participants were randomly assigned to the intervention or control group. Results show that a Mediterranean diet–based nutritional intervention enriched with extra virgin olive oil compared with usual care, resulted in a significantly greater increase in HRQoL in recovered depressed patients. This association was greater for the mental dimensions rather than the physical dimensions. Furthermore, this association was also observed for participants aged 60 or more. Authors conclude that since depression is an important condition for its high prevalence, economic cost and personal suffering, it is important to evaluate cost-effective, safe, and inexpensive interventions, such as Mediterranean Diet nutritional interventions.
Abstract
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.

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.

Summary Review:
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
Omega-3 fatty acids such as docosahexaenoic acid (DHA) are thought to be beneficial for the development of the fetal brain. Women with a singleton pregnancy at <21 weeks’ gestation enrolled in this multicentre, double-blind, randomised controlled trial to assess the fetal neurodevelopment effects of 800 mg/day, which they took until the birth of their children. A follow-up assessment was arranged when the children reached age seven to evaluate their neurodevelopment. Children of women who took DHA supplements showed increased risk scores on hyperactivity, behavioural problems that may impact daily activities, ADHD, peer relationships, Metacognition Indexes, Shift, Inhibit, Monitor, Working Memory, and Organization of Materials scales. Supplementing with high doses of DHA during pregnancy might not have any protective effects on neurodevelopment in women with high baseline DHA levels. However, further robust studies are required to confirm the results to determine the clinical applicability of DHA supplementation in pregnant women. Healthcare professionals can use the results of this study to understand the dose-dependent therapeutic application of DHA and its impact on fetal neurodevelopment.
Abstract
Docosahexaenoic acid (DHA) accumulates in the fetal brain during pregnancy and is thought to have a role in supporting neurodevelopment. We conducted a multicenter, double-blind, randomized controlled trial in women with a singleton pregnancy who were <21 weeks' gestation at trial entry. Women were provided with 800 mg DHA/day or a placebo supplement from trial entry until birth. When children reached seven years of age, we invited parents to complete the Strengths and Difficulties Questionnaire (SDQ), the Behavior Rating Inventory of Executive Function (BRIEF), and the Conners 3rd Edition Attention-Deficit Hyperactivity Disorder (ADHD) Index to assess child behavior and behavioral manifestations of executive dysfunction. There were 543 parent-child pairs (85% of those eligible) that participated in the follow-up. Scores were worse in the DHA group than the placebo group for the BRIEF Global Executive, Behavioral Regulation and Metacognition Indexes, and the Shift, Inhibit, Monitor, Working Memory, and Organization of Materials scales, as well as for the Conners 3 ADHD index, and the SDQ Total Difficulties score, Hyperactivity/Inattention score, and Peer Relationship Problems score. In this healthy, largely term-born sample of children, prenatal DHA supplementation conferred no advantage to childhood behavior, and instead appeared to have an adverse effect on behavioral functioning, as assessed by standardized parental report scales.

Plain language summary
Type 2 Diabetes is considered a lifelong condition, but calorie restriction or weight loss can lead to complete remission. Patients newly diagnosed with Type 2 Diabetic may benefit from behavioural change over the long run. When Type 2 Diabetes is diagnosed early in the disease trajectory, it may increase the patient's motivation and make them more receptive to weight-loss interventions. This prospective cohort study included 865 newly diagnosed Type 2 diabetic patients from the ADDICTION Cambridge Trial, a pragmatic, parallel-group cluster randomised controlled trial. The study assessed the relationship between behaviour change and weight loss and the prospect of type 2 diabetes remission in the first year, following four years and after five years without intense dietary or lifestyle intervention in patients. 30% of the patients achieved diabetes remission at 5-year follow-up, with a significant likelihood of remission among those who achieved ≥ 10% weight loss in the first year of diagnosis. A self-reported change in intake of alcohol units was found to be the only consistent association between behaviour change and remission in this study. The role of behaviour change in the remission of diabetes requires further robust research. This study will help healthcare professionals understand the association between weight loss and remission in diabetic patients.
Abstract
AIM: To quantify the association between behaviour change and weight loss after diagnosis of Type 2 diabetes, and the likelihood of remission of diabetes at 5-year follow-up. METHOD We conducted a prospective cohort study in 867 people with newly diagnosed diabetes aged 40-69 years from the ADDITION-Cambridge trial. Participants were identified via stepwise screening between 2002 and 2006, and underwent assessment of weight change, physical activity (EPAQ2 questionnaire), diet (plasma vitamin C and self-report), and alcohol consumption (self-report) at baseline and 1 year after diagnosis. Remission was examined at 5 years after diabetes diagnosis via HbA1c level. We constructed log binomial regression models to quantify the association between change in behaviour and weight over both the first year after diagnosis and the subsequent 1-5 years, as well as remission at 5-year follow-up. RESULTS Diabetes remission was achieved in 257 participants (30%) at 5-year follow-up. Compared with people who maintained the same weight, those who achieved ≥ 10% weight loss in the first year after diagnosis had a significantly higher likelihood of remission [risk ratio 1.77 (95% CI 1.32 to 2.38; p<0.01)]. In the subsequent 1-5 years, achieving ≥10% weight loss was also associated with remission [risk ratio 2.43 (95% CI 1.78 to 3.31); p<0.01]. CONCLUSION In a population-based sample of adults with screen-detected Type 2 diabetes, weight loss of ≥10% early in the disease trajectory was associated with a doubling of the likelihood of remission at 5 years. This was achieved without intensive lifestyle interventions or extreme calorie restrictions. Greater attention should be paid to enabling people to achieve weight loss following diagnosis of Type 2 diabetes.

Childhood obesity rates are high in both developed and developing countries. The most important contributors are the increased availability of energy-dense foods and a reduced need for physical activity. The aim of the study was to examine the association between self-reported emotional eating, health behaviours and body mass index in 9 to 11-year-old children. The study is a secondary analysis of the International Study of Childhood Obesity, Lifestyle and Environment. The cross-sectional sample included 5,426 children with an age range between 9 to 11-year-olds. Results indicate a positive association between emotional eating and an unhealthy diet pattern, which was consistent in all 12 different study sites. Authors conclude that the association between emotional eating and an unhealthy eating pattern is not restricted to Western countries and their cultural and food environments.
Abstract
Eating in response to negative emotions (emotional eating, EE) may predispose an individual to obesity. Yet, it is not well known how EE in children is associated with body mass index (BMI) and health behaviours (i.e., diet, physical activity, sleep, and TV-viewing). In the present study, we examined these associations in a cross-sectional sample of 5426 (54% girls) 9⁻11-year-old children from 12 countries and five continents. EE, food consumption, and TV-viewing were measured using self-administered questionnaires, and physical activity and nocturnal sleep duration were measured with accelerometers. BMI was calculated using measured weights and heights. EE factor scores were computed using confirmatory factor analysis, and dietary patterns were identified using principal components analysis. The associations of EE with health behaviours and BMI z-scores were analyzed using multilevel models including age, gender, and household income as covariates. EE was positively and consistently (across 12 study sites) associated with an unhealthy dietary pattern (β = 0.29, SE = 0.02, p < 0.0001), suggesting that the association is not restricted to Western countries. Positive associations between EE and physical activity and TV viewing were not consistent across sites. Results tended to be similar in boys and girls. EE was unrelated to BMI in this sample, but prospective studies are needed to determine whether higher EE in children predicts the development of undesirable dietary patterns and obesity over time.

Nutrition may play an important role in the prevention of dementia. The aim of this study was to evaluate the effect of a multinutrient supplementation rich in omega-3 fatty acids on the cognitive function of adults aged 75 years and over with either no, or mild, cognitive impairment. Participants were given either a multinutrient capsule (each containing DHA 250 mg, EPA 40 mg, vitamin E 5 mg, phosphatidylserine 15 mg, tryptophan 95 mg, vitamin B 12 5 μg, folate 250 μg and ginkgo biloba 60 mg) or a placebo, three times a day for one year. Supplementation with the multinutrient did not improve overall cognitive function in the group. However, it did result in an improvement in memory in a sub-group of older people who were previously well nourished, but not in those with worse nutritional status.
Abstract
A few studies have assessed the association between omega-3 polyunsaturated fatty acids (n-3 PUFA) and cognitive impairment (CI) in very old adults. The aim of this study was to evaluate the effect of a multinutrient supplementation rich in n-3 PUFA on the cognitive function in an institutionalized ≥75-year-old population without CI or with mild cognitive impairment (MCI). A multicenter placebo-controlled double-blind randomized trial was conducted between 2012 and 2013. Cognitive function was assessed at baseline and after one year using 4 neuropsychological tests. Nutritional status was assessed using Mini Nutritional Assessment (MNA). Interaction between Mini-Mental State Examination (MMSE) score and nutritional status were analyzed using linear regression models. A total of 99 participants were randomized to receive placebo or pills rich in n-3 PUFA. After 1-year follow-up, both groups decreased their MMSE score (-1.18, SD:0. 53 and -0.82, SD:0. 63, p = 0.67 for the control and the intervention group respectively). The memory subscale of the MMSE showed an improvement (+0.26, SD:0.18) in the intervention group against a worsening in the control group (-0.11, SD: 0.14; p = 0.09 for differences between groups). Patients at intervention group with normal nutritional status (MNA ≥24) showed an improvement in the MMSE (+1.03, p = 0.025 for differences between 1-y and baseline measurements) against a worsening in the group with malnutrition (MNA<24) (-0.4, p = 0.886 for differences between 1-y and baseline; p of interaction p = 0.05). Supplementation with n-3 PUFA did not show an improvement in the global cognitive function in institutionalized elderly people without CI or with MCI. They only suggest an apparent improvement in memory loss if previously they were well nourished.

Children who are overweight or obese have higher rates of eating disorder pathology (extreme dietary restraint, loss of control eating and emotional eating) than their peers who are not overweight or obese, thus having an increased risk of developing a clinical eating disorder. The aim of the study is to classify overweight or obese children entering family-based treatment into groups with distinct patterns of eating disorder pathology and then examine eating disorder pattern differences in 3 categories. The study includes data from a multi-site randomised controlled trial. The analysis focused on data from the initial weight loss phase which included 241 obese or overweight children aged between 7 to 11 years. Results showed that eating disorders are more common among females than males, yet males also experience high levels of eating disorder pathology. Levels of eating disorder pathology decreased after family-based behavioural weight-loss treatment and so decreased the risk of the development of a clinical eating disorder. Authors conclude that eating disorder pathology is prevalent among children with overweight or obesity but has varying presentations.
Abstract
OBJECTIVE Children with overweight or obesity have elevated eating disorder (ED) pathology, which may increase their risk for clinical EDs. The current study identified patterns of ED pathology in children with overweight or obesity entering family-based behavioral weight loss treatment (FBT) and examined whether children with distinct patterns differed in their ED pathology and BMI z score (zBMI) change across FBT. METHODS Before participating in a 16-session FBT, children (N = 241) completed surveys or interviews assessing ED pathology (emotional eating, shape/weight/eating concerns, restraint, and loss of control [LOC]). Shape and weight concerns (SWC) and LOC were also assessed post treatment. Child height and weight were measured at baseline and post treatment. Latent class analysis identified patterns of ED pathology. Repeated-measures ANOVA examined changes in zBMI and ED pathology. RESULTS Four patterns of ED pathology were identified: low ED pathology, SWC, only loss of control, and high ED pathology. SWC decreased across treatment, with the highest decreases in patterns characterized by high SWC. All groups experienced significant decreases in zBMI; however, children with the highest ED pathology did not achieve clinically significant weight loss. CONCLUSIONS ED pathology decreased after FBT, decreasing ED risk. While all children achieved zBMI reductions, further research is needed to enhance outcomes for children with high ED pathology.

Migraine is a functional disorder of the brain. Non-medical, non-pharmacological and pharmacological treatments are recommended for the prevention of migraine. The aim of this study was to evaluate the efficacy of a proprietary nutritional supplement containing a fixed combination of magnesium, riboflavin and Q10 as prophylactic treatment for migraine. This study is a randomized double-blind placebo controlled, multicentre trial. The study enrolled 173 participants for the baseline phase of which 130 were randomised to one of the two groups; supplement (n=64) or placebo (n=66). Results show a reduction of migraine pain and burden of disease after 3 months of treatment with the supplement. Patients rated the efficacy of the treatment significantly superior to placebo. Furthermore, abdominal discomfort and diarrhoea due to high amounts of magnesium were the main adverse events associated with the supplement. Authors conclude that the nutritional supplement had a trend towards statistical significance in the reduction of migraine days, probably due to being underpowered. Migraine symptoms and burden of disease, however, were statistically significantly reduced compared to placebo. Healthcare practitioners could use the results of this study to consider supplementation with the studied nutrients when working with migraine patients.
Abstract
BACKGROUND Non-medical, non-pharmacological and pharmacological treatments are recommended for the prevention of migraine. The purpose of this randomized double-blind placebo controlled, multicenter trial was to evaluate the efficacy of a proprietary nutritional supplement containing a fixed combination of magnesium, riboflavin and Q10 as prophylactic treatment for migraine. METHODS 130 adult migraineurs (age 18 - 65 years) with ≥ three migraine attacks per month were randomized into two treatment groups: dietary supplementation or placebo in a double-blind fashion. The treatment period was 3 months following a 4 week baseline period without prophylactic treatment. Patients were assessed before randomization and at the end of the 3-month-treatment-phase for days with migraine, migraine pain, burden of disease (HIT-6) and subjective evaluation of efficacy. RESULTS Migraine days per month declined from 6.2 days during the baseline period to 4.4 days at the end of the treatment with the supplement and from 6.2.days to 5.2 days in the placebo group (p = 0.23 compared to placebo). The intensity of migraine pain was significantly reduced in the supplement group compared to placebo (p = 0.03). The sum score of the HIT-6 questionnaire was reduced by 4.8 points from 61.9 to 57.1 compared to 2 points in the placebo-group (p = 0.01). The evaluation of efficacy by the patient was better in the supplementation group compared to placebo (p = 0.01). CONCLUSIONS Treatment with a proprietary supplement containing magnesium, riboflavin and Q10 (Migravent® in Germany, Dolovent® in USA) had an impact on migraine frequency which showed a trend towards statistical significance. Migraine symptoms and burden of disease, however, were statistically significantly reduced compared to placebo in patients with migraine attacks.
