Plain language summary
Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder characterised by inattention and/or hyperactivity/impulsivity. Several studies have found bidirectional associations between ADHD and diabetes mellitus (DM). The aims of this study were to assess the prevalence of ADHD in DM patients as well as the prevalence of DM in ADHD patients compared with those without ADHD, and to explore the impacts of ADHD on glycaemic control in patients with DM. This study is a systematic review and meta-analysis of 17 articles; five were cohort studies, three were case-control studies, and nine were cross-sectional studies. Results through the pooled analyses suggest an important comorbid relationship between diabetes and ADHD. Overall, there was an increase in T2DM of 166% and 51% in children and adults with ADHD, respectively, relative to those without ADHD. Furthermore, there was an overall 37% increase in T1DM in children with ADHD. Authors conclude that further studies are needed to better understand the relationship between ADHD and DM. Additionally, it is important to take into consideration the type of DM if this association is different in various age groups (children and adults).
Abstract
BACKGROUND This study aims to investigate the prevalence estimate of diabetes mellitus (DM) among people with attention deficit hyperactivity disorder (ADHD) as well as the prevalence of ADHD among those with DM. In addition, the impact of ADHD on glycemic control in patients with DM was also assessed using a systematic review and meta-analysis of currently available published data. MATERIALS AND METHODS The PubMed, Embase, Web of Science, and PsycInfo databases were searched for potential studies. Two reviewers independently selected studies according to the inclusion and exclusion criteria. All pooled analyses were conducted using the random-effects models on Review Manager 5.3. RESULTS Seventeen observational studies were included. The pooled results showed an increase in the prevalence of DM among patients with ADHD versus those without ADHD [type 1 DM OR 1.37 (95% CI: 1.17-1.61); type 2 DM OR 2.05 (95% CI: 1.37-3.07)]. There was an overall 35% increase in the prevalence of ADHD among patients with type 1 DM [OR: 1.35 (95% CI: 1.08-1.73)]. Children with type 1 DM and ADHD had higher levels of hemoglobin A1c [standardized mean of differences: 0.67 (95% CI: 0.48-0.86)], and prevalence of hypoglycemic and ketoacidosis index compared with those without ADHD. CONCLUSION Our study revealed the bidirectional associations between ADHD and DM. Patients with ADHD and type 1 DM comorbidities were more likely to have poorer diabetes control. More studies are needed to confirm this association and elucidate the underlying mechanism.

Plain language summary
Mediterranean Diet (MD) is currently considered one of the healthiest dietary models worldwide due to the high intake of antioxidants, dietary fibre, monounsaturated and omega-3 fatty acids, phytosterols and probiotics. The aim of this review was to present current literature showing evidence on the possible impact of MD on health and mental health. The review was based on 27 articles of which 13 were carried out in Spain, 3 in the USA, 3 in Italy, 4 in Australia and 4 in other EU countries. Literature shows that MD improves: - metabolic cardiovascular parameters with a reduced incidence of major cardiovascular events by approximately 30%. - metabolic balance in patients affected by type 2 diabetes mellitus. - biochemical markers for metabolic disorders as well as in patients at risk of specific cancer diseases. Additionally, not enough data is available on the MD effects on specific psychopathological issues. In fact, besides adherence to MD, other factors - which should be further investigated - also play a role in the effectiveness of the MD. Authors conclude that further studies are needed to address the efficacy of diet as an adjunctive treatment for mental disorders as well as for the management of comorbid cardiovascular and metabolic issues.
Abstract
Mediterranean Diet (MD) is currently considered one of the most healthy dietary models worldwide. It is generally based on the daily intake of fruit and vegetables, whole grains, legumes, nuts, fish, white meats, and olive oil. It may also include moderate consumption of fermented dairy products, a low intake of red meat, and red/white wine during the main course. Even if the effect of MD on cancer prevention as well as on human metabolic and cardiovascular balance has been discussed, including the quality of life of the exposed population, the putative effects on mental health are still not properly investigated. This narrative review reports on some emerging pieces of evidence on the possible impact of MD on general health and the outcome of psychiatric disorders (e.g., major depression, anxiety) and encourages further studies to test the benefits of healthy food selection on the health of the general population.
