Background/Objectives: Multiple sclerosis (MS) is an autoimmune neuroinflammatory disease affecting 2.9 million worldwide. Current immunosuppressive treatments offer limited neuroprotection and often cause adverse effects. Polyphenols with antioxidant and anti-inflammatory properties have been investigated as adjuncts in MS. Methods: On 19 June 2025, Embase, Medline, and ClinicalTrials.gov were systematically searched. Eligible clinical trials assessing polyphenol supplementation in MS were included. Outcomes of interest were Expanded Disability Status Scale (EDSS), annualised relapse rate (ARR), magnetic resonance imaging (MRI) changes, safety, and tolerability. Risk of bias was evaluated using the Cochrane tool, and certainty of evidence was appraised with Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The protocol was registered with PROSPERO (CRD420251052042). Results: Of 870 records identified, 13 trials (n = 785) met inclusion. Nanocurcumin consistently improved EDSS in relapsing–remitting MS (3 trials, n = 150; p = 0.039–0.041), while epigallocatechin-3-gallate, silymarin (SM), cranberry extract, and bio-enhanced curcumin extract (BCM-95) curcumin showed no significant impact on disability, relapse rates, or MRI outcomes. Intervention adverse events were generally mild. SM showed potential hepatoprotective effects. Risk of bias was determined as low risk for seven of the trials and of some concern for five of the studies. Most often raising concerns because of selective reporting. Certainty of evidence, assessed using GRADE, was generally moderate, indicating some uncertainty regarding the outcomes. Meta-analysis was not possible due to the heterogeneity of included studies. Conclusions: Nanocurcumin may contribute to improvements in disability outcomes in Relapse Remitting Multiple Sclerosis (RRMS), whereas other polyphenols lack consistent efficacy. However, the evidence base remains limited by small sample sizes and methodological concerns. Larger, multicentre randomised controlled trials are required to establish optimal dosing, long-term safety, and therapeutic potential.

This article discusses the overweight/obesity situation among young adults in developing countries. For this target population, obesity prevalence ranges from 2.3 to 12 %, and overweight is 28.8 %, mostly affecting females. Weight is now increasing during this life stage of transition at a higher rate, 1 kg/year, than in developed countries. Maternal factors and early childhood socioeconomic status are associated with BMI in young adults along with changing environmental and behavioural factors in some low and middle income countries, brought about by demographic and socioeconomic transitions. Young adults with ‘normal weight’ obesity need identification using other convenient low cost measures (skin folds or waist circumference) along with BMI. Obesity prevention or management interventions were not identified, but clearly needed to help stem the obesity pandemic. Young people generally give little priority to their future health, so such interventions need to be conducted at some optimal age, be innovative, country specific and culturally acceptable.

Child undernutrition has short and long term consequence for both individuals and society. Previous studies show probiotics may promote child growth and have an impact on under-nutrition. A systematic review of the literature was carried out on three electronic databases to assess evidence. The outcome measured was change in weight or height. A narrative analysis was conducted due to heterogeneity of included studies. Twelve studies were included in the review of which ten were randomised controlled trials. A total of 2757 children were included, with 1598 from developing countries. The studies varied in type and quantity of probiotics given, duration of interventions, characteristics of participants, setting and units of outcome measures. Overall, five studies found a positive effect of probiotics on child growth. All five were conducted in developing countries with four studies conducted in mostly under-nourished children and one in well-nourished children. No significant effect on growth was found in the seven studies that were conducted in developed countries. The limited evidence suggests that probiotics have the potential to improve child growth in developing countries and in under-nourished children. More research is needed to explore this further.

Background: Young people (18–25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, diet behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore diet behaviour among 18–25 year olds with influential factors including attitudes, motivators and barriers. Methods: An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at University/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted and the results from this were incorporated into the qualitative phase. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi-staged modelling to analyse the quantitative data. ‘Framework Analysis’ was used to analyse the focus groups. Results: 1313 questionnaires were analysed. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the survey, 40% of young people reported eating an adequate amount of fruits and vegetables and 59% eating regular meals, but 32% reported unhealthy snacking. Based on the statistical modelling, positive attitudes towards diet and high intention (89%), did not translate into healthy diet behaviour. From the focus group discussions, the main motivators for diet behaviour were ‘self-appearance’ and having ‘variety of food’. There were mixed opinions on ‘cost’ of food and ‘taste’. Conclusion: Elements deemed really important to young people have been identified. This mixed method study is the largest in this vulnerable and neglected group covering a wide spectrum of the community. It provides evidence base to inform tailored interventions for a healthy diet within this age group.

Young people (18–25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, physical activity behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore physical activity (PA) behaviour among 18–25 year olds with influential factors including attitudes, motivators and barriers.

Summary: This systematic review assesses weight loss interventions in young adults (18–25 years), who are vulnerable to weight gain. This age group experience critical life course points (leaving home for higher studies or job, pregnancy, cohabitation) and develop/establish lifestyle and behavioural patterns making this an opportune intervention period. Medline, Embase, Cinahl, PsychINFO and Cochrane Library were searched (1980 to March 2008). All trials and cohort studies with control groups that assessed weight loss interventions in this specific age group were included finally identifying 14 studies. Before and after comparison of behavioural/motivational interventions (−2.40 kg; 95% CI −5.4 to 0.6) and combination interventions (−2.96; 95% CI −4.4 to −1.5) consistently showed weight loss. Behavioural/motivational interventions increased self‐efficacy, the desire to control weight, boosted self‐esteem, and increased satisfaction with body areas and appearance. Interventions also showed improvements in HDL cholesterol, insulin, glucose and maximum oxygen uptake. However, recruitment to participation in interventions was a barrier for this age group with small sample sizes and short‐term interventions. There may be gender differences in preference to participation in certain type of interventions. Further research to understand attitudes towards healthy lifestyle and preferences of interventions is needed to develop suitable interventions for this vulnerable age group.

There is considerable expertise in the obesity field in identifying, appraising, and synthesising evidence to develop guidelines and recommendations for policy and practice. The recommendations, while based on evidence, are not formulated in a way that readily leads to implementation. This paper analyses the recent UK recommendations on obesity using a proposed implementation framework.

The purpose of this paper is to conduct a review of reviews to identify characteristics of effective sex and relationship education (SRE) interventions and/or programmes in young people to improve sexual health and identify barriers and facilitators for implementation. Six bibliographic databases were searched from 1986 to 2006 for systematic reviews that assessed SRE interventions or programmes in participants between 10 and 18 years old and their partners. All outcomes of improvement in sexual health were assessed and 30 systematic reviews were included. Effective interventions and/or programmes tended to be those targeting younger age groups before they become sexually active, focused interventions tailored to the physical and biological development stages, theory based, and abstinence education programmes that incorporate values of relationships and provide skills training and links to contraceptive services. Adequate training of personnel delivering the interventions and culturally sensitive programmes were identified as important facilitators of effectiveness. Future research should explore the appropriate age for initiating sex education and investigate targeting specific behaviour compared with multiple-outcome targeting. Research exploring the reasons for interventions focusing on specific populations (i.e. African and Hispanic origins), even if they were conducted in countries dominated by Caucasians, is warranted.

The HIV/AIDS epidemic remains of global significance and there is a need to target (a) the adolescent age-groups in which most new infections occur; and (b) sub-Saharan Africa where the greatest burden of the epidemic lies. A focused systematic review of school-based sexual health interventions in sub-Saharan Africa to prevent HIV/AIDS and Sexually Transmitted Infections (STI) in this age group was therefore conducted.
