Objectives To examine cross-sectional associations of socioeconomic status (ie, income and education) with an adherence to a Mediterranean dietary pattern and obesity prevalence. Design Cross-sectional study on a sample of Italian subjects enrolled in the Moli-sani Project, a population-based cohort study. The Italian EPIC food frequency questionnaire was used to determine food intake. Adherence to a Mediterranean diet (MD) was appraised according to both the Mediterranean score elaborated by Trichopoulou (MDS) and the novel Italian Mediterranean Index (IMI) and to the a posteriori scores derived from principal component analysis. Four income categories were identified. Setting Molise region, Italy. Participants 13 262 subjects (mean age 53±11, 50% men) out of 24 318 citizens (age ≥35) randomly enrolled in the Moli-sani Project. Main outcomes Dietary patterns and risk factors for cardiovascular disease. Results Household higher income were significantly associated with greater adherence to an MD (p<0.0001) and to Olive oil and Vegetables dietary pattern in a multivariable model including age, sex, daily energy intake, body mass index, physical activity, smoking, alcohol consumption, education and marital status. The odds of having the highest adherence to an MD clearly increased according to income levels. People having the highest income had 54% (95% CI 21% to 97%, MDS) or 72% (95% CI 34% to 121%, IMI) higher probability to stick to an MD-like eating pattern than those in the lowest-income group. Obesity prevalence was higher in the lowest-income group (36%) in comparison with the highest-income category (20%, p<0.0001). Income was associated with dietary patterns in all categories of education. Conclusions A higher income and education are independently associated with a greater adherence to MD-like eating patterns and a lower prevalence of obesity.

PurposeTo evaluate in an Italian general population, the association with mortality of a traditional Mediterranean diet (MD) and non-Mediterranean dietary (non-MD) patterns, and their combined effect, and to test some biomarkers of cardiovascular (CVD) risk as potential mediators of such associations.MethodsLongitudinal analysis on 22,849 men and women aged ≥ 35 years, recruited in the Moli-sani Study (2005–2010), followed up for 8.2 years (median). The MD was assessed by the Mediterranean diet score (MDS). The Dietary Approaches to Stop Hypertension (DASH), the Palaeolithic diet, and the Nordic diet were chosen as reportedly healthy non-MD patterns. Hazard ratios (HR) with 95% confidence intervals (95% CI) were calculated by multivariable Cox regression.ResultsParticipants reaching higher MDS or DASH diet score experienced lower risk of both all-cause (HR 0.77; 95% CI 0.66–0.90 and 0.81; 0.69–0.96, respectively, highest vs lowest quartile) and CVD (0.77; 0.59–1.00 and 0.81; 0.69–0.96, respectively) death risk; risk reduction associated with the Palaeolithic diet was limited to total and other cause death, whereas the Nordic diet did not alter risk of mortality. Increasing adherence to MD was associated with higher survival in each stratum of non-MD diets. Biomarkers of glucose metabolism accounted for 7% and 21.6% of the association between either MDS or DASH diet, respectively, with total mortality risk.ConclusionsBoth the traditional MD and DASH diet may reduce risk of all-cause mortality among Italians, as well as risk of dying from cardiovascular causes. The Palaeolithic diet did not appear to reduce cardiovascular risk, while the Nordic eating pattern was unlikely to be associated with any substantial health advantage.

Protease proprotein convertase subtilisin/kexin type 9 (PCSK9) is a regulator of LDL cholesterol clearance and has been associated with cardiovascular risk. PCSK9 inhibitors increase in vivo circulating endothelial progenitor cells (EPCs), a subtype of immature cells involved in ongoing endothelial repair. We hypothesized that the effect of PCSK9 on vascular homeostasis may be mediated by EPCs in patients with or without type 2 diabetes mellitus (T2DM). Eighty-two patients (45 with, 37 without T2DM) at high cardiovascular risk were enrolled in this observational study. Statin treatment was associated with higher circulating levels of PCSK9 in patients with and without T2DM (p < 0.001 and p = 0.036) and with reduced CD45 neg /CD34 bright (total EPC compartment) (p = 0.016) and CD45 neg /CD34 bright /CD146 neg (early EPC) (p = 0.040) only among patients with T2DM. In the whole group of patients, statin treatment was the only independent predictor of low number of CD45 neg /CD34 bright (β = − 0.230; p = 0.038, adjusted R 2  = 0.041). Among T2DM patients, PCSK9 circulating levels were inversely related and predicted both the number of CD45 neg /CD34 bright (β = − 0.438; p = 0.003, adjusted R 2  = 0.173), and CD45 neg /CD34 bright /CD146 neg (β = − 0.458; p = 0.002, adjusted R 2  = 0.191) independently of age, gender, BMI and statin treatment. In high-risk T2DM patients, high endogenous levels of PCSK9 may have a detrimental effect on EPCs by reducing the endothelial repair and worsening the progression of atherothrombosis.

Objectives: To estimate psychological distress experienced during the Italian lockdown (March-May 2020) by assessing, in the transition period of the pandemic (June-September 2020), participants’ recalling of their psychological state.Methods: Cross-sectional analysis on 1,880 adults (mean age 48.9 ± 14.5 years) from the web-based ALT RISCOVID-19 survey. Participants were asked to retrospectively recall their psychological state during lockdown concerning symptoms of depression (Patients’ Health Questionnaire), anxiety (General Anxiety Disorder), stress (Perceived Stress Scale) and post-traumatic stress (Screening Questionnaire for Disaster Mental Health).Results: Experienced symptoms of depression, anxiety and post-traumatic stress was recalled by 15.8, 15.3 and 13.1% of respondents, respectively. These psychometric scales tended to decrease during the 4-month period of assessment ( p < 0.05), while perceived stress levels did not ( p = 0.13). Men and older individuals reported lower symptoms of depression ( β = −0.42 and β = −0.42; p < 0.0001, respectively), anxiety ( β = −0.41 and β = −0.45; p < 0.0001, respectively), stress ( β = −0.36 and β = 0.50; p < 0.0001, respectively) and post-traumatic stress ( β = −0.42; p < 0.0001, men vs women).Conclusion: Recalled psychological distress experienced during COVID-19 lockdown tended to decrease during the transition period of the pandemic, except for stress. Women and younger people were at higher risk to recall psychological distress.

To assess ultra-processed food (UPF) consumption and its socio-demographic, psychosocial and behavioural correlates in a general population of Italian children, adolescents and adults. Cross-sectional telephone-based survey. Italy, 2010-2013. In total, 9078 participants (5-97 years) from the Italian Nutrition & Health Survey. Dietary intakes were collected by a 1-d 24-h dietary recall. UPF was defined by the NOVA classification and expressed as percentage of total energies. Average energy intake from UPF (95 % CI) was 17·3 % (17·1 %, 17·6 %) among adults and 25·9 % (24·8 %, 27·0 %) in children/adolescents. Top sources of UPF were processed meats (32·5 %) and bread substitutes (16·7 %). Among adults, age (β = -3·10; 95 % CI (-4·40, -1·80) for >65 years v. 20-40 years; βs are dimensionless) and residing in Southern Italy (β = -0·73; 95 % CI (-1·32, -0·14) v. Northern) inversely associated with UPF. Screen view during meals was directly linked to UPF, as well as poor self-rated health (β = 5·32; 95 % CI (2·66, 7·99)), adverse life events (β = 2·33; 95 % CI (1·48, 3·18)) and low sleep quality (β = 2·34; 95 % CI (1·45, 3·23)). Boys consumed two-point percent more UPF of the total energy than girls (β = 2·01; 95 % CI (0·20, 3·82)). For all ages, a Mediterranean diet was inversely associated with UPF (β = -4·86; 95 % CI (-5·53, -4·20) for good v. poor adherence in adults and (β = -5·08; 95 % CI (-8·38, -1·77) for kids). UPF contributes a modest proportion of energy to the diets of Italian adults while being one-quarter of the total energies in children/adolescents. UPF was associated with several psychosocial factors and eating behaviours. Increased adherence to Mediterranean diet would possibly result in lower UPF consumption.

Background/Objectives: Neuromedin U (NMU) is a highly conserved gene encoding a neuropeptide involved in the regulation of feeding behavior and energy homeostasis. We aimed to analyze the association between NMU genetic and epigenetic variations and cardio-metabolic parameters in an Italian population to identify the role of these variants in cardio-metabolic risk. Methods: A total of 4028 subjects were randomly selected from the Moli-sani study cohort. NMU haplotypes were estimated using seven SNPs located in the gene body and in the promoter region; DNA methylation levels in the promoter region, previously associated with lipid-related variables in the same population, were also used. Results: Among the haplotypes inferred, the haplotype carrying the highest number of minor variants (frequency 16.6%), when compared with the most frequent haplotype, was positively associated with insulin levels, HOMA-IR, and diastolic blood pressure, and negatively with HDL-cholesterol. The multivariable analysis that considered methylation levels along with their interactions with SNPs showed that increased methylation levels in two close CpG sites were associated with higher levels of lipid-related variables. Conclusions: This study supports a role for NMU as a regulator of human metabolism. This finding suggests that NMU could be a potential target for preventive interventions against coronary and cerebrovascular diseases, and that NMU genetic and epigenetic variability may serve as a biomarker for cardio-metabolic risk.

AbstractObjectiveTo jointly analyse two food dimensions, the Food Standards Agency Nutrient Profiling System (FSAm-NPS), used to derive the Nutri-Score front-of-pack label, and the NOVA classification in relation to mortality.DesignProspective cohort study.SettingMoli-sani Study, Italy 2005-10.Participants22 895 participants (mean age 55 (SD 12) years; 48% men).Main outcomes measuresAssociations between dietary exposures and mortality risk, assessed using multivariable cause specific Cox proportional hazard models controlled for known risk factors.ResultsA total of 2205 deaths occurred during 272 960 person years of follow-up. In the highest quarter of the FSAm-NPS index compared with the lowest quarter, multivariable adjusted hazard ratios for all cause and cardiovascular mortality were 1.19 (95% confidence interval 1.04 to 1.35; absolute risk difference 4.3%, 95% confidence interval 1.4% to 7.2%) and 1.32 (1.06 to 1.64; 2.6%, 0.3% to 4.9%), respectively. The hazard ratios were 1.19 (1.05 to 1.36; absolute risk difference 9.7%, 5.0% to 14.3%) and 1.27 (1.02 to 1.58; 5.0%, 1.2% to 8.8%), respectively, for all cause and cardiovascular mortality when the two extreme categories of ultra-processed food intake were compared. When these two indices were analysed jointly, the magnitude of the association of the FSAm-NPS dietary index with all cause and cardiovascular mortality was attenuated by 22.3% and 15.4%, respectively, whereas mortality risks associated with high ultra-processed food intake were not altered.ConclusionsAdults with the lowest quality diet, as measured using the FSAm-NPS dietary index (underpinning the Nutri-Score), and the highest ultra-processed food consumption (NOVA classification) were at the highest risk for all cause and cardiovascular mortality. A significant proportion of the higher mortality risk associated with an elevated intake of nutrient poor foods was explained by a high degree of food processing. In contrast, the relation between a high ultra-processed food intake and mortality was not explained by the poor quality of these foods.

Folate status has been associated with neural tube defects and cerebrovascular disease. The aim of this study was to evaluate possible differences in folate status in two European Union countries and to assess their possible association with dietary patterns and/or other lifestyles. In the framework of the European Union-funded IMMIDIET Project, 1068 individuals (534 male–female pairs), ages 26 to 64 y, were enrolled in Italy and the United Kingdom. One-year-recall food frequency questionnaire was used to evaluate dietary intake. Reduced rank regression analysis was used to derive a dietary pattern better describing high dietary folate intake. Of the total participants, 11.3% of the Italians and 45.1% of the British exceeded the optimal dietary folate intake of 400 μg/d (Recommended Dietary Allowance). Of the women, 66.7% and 22.1% of Italian and British women, respectively, all at childbearing age, had folate serum levels <6.62 ng/mL (P = 0.01). The percentage of total variance of dietary folate intake explained by food group consumption was 14.2% and 16.3% in Italy and the United Kingdom, respectively. Reduced rank regression analysis indicated a healthy pattern that was positively associated with folate serum levels in both countries (for all β-coefficients >0; P < 0.001): 100 μg/d increase in dietary folate intake was associated with 13.8% and 10.5% increase in folate serum levels in the Italian and British population, respectively (for 100 μg/d increase eβ-coef = 1.138 and 1.105; P < 0.001). Smoking habit was negatively but physical activity positively associated with folate serum levels (P < 0.05). An inadequate dietary folate intake and subsequent serum levels were observed in the Italian participants. High consumption of food sources of folate was positively associated with folate serum levels, explaining a good proportion of its variability.

Background/objectivesDiabetic subjects are at increased risk of subtle cognitive impairment since the disease early stages and of dementia later in life. In animal models, glucagon-like peptide-1 receptor agonizts (GLP1-RAs) have been shown to exert neuroprotective effects, expecially in the memory domain. We assessed whether treatment with a GLP1-RA might affect cognitive functions in type 2 diabetic subjects independently on the weight loss it might induce.Subjects/methodsForty metformin-treated obese subjects with prediabetes or newly diagnosed type 2 diabetes mellitus, received liraglutide (1.8 mg/d) (n = 20) or lifestyle counseling (dietary intervention and exercise training) (n = 20) until achieving a modest and comparable weight loss (−7% of initial body weight).Interventions/methodsA detailed neuropsychological assessment before and after weight loss was completed in 16 patients per arm, who were administered a total of seven psychological tests, thus assessing three composite domain z-scores for attention, memory, and executive control.ResultsAfter comparable weight loss and superimposable glycemic control and insulin sensitivity, a significant increase in short term memory (mean Digit Span Z score from −0.06 to 0.80, p = 0.024) and memory composite z-score (mean memory z-score from −0.67 to 0.032, p = 0.0065) was observed in the liraglutide exposed subjects (between group p = 0.041 and p = 0.033, respectively).ConclusionsLiraglutide might slow down memory function decline in diabetic patients in early, and possibly preclinical stages of the disease.

To evaluate changes in ultra-processed food (UPF) intake and its major correlates during the first Italian lockdown (March 9 -May 3 2020). Retrospective observational study. Italy. We analysed 2,992 subjects (mean age 57.9±15.3 y, 40.4% men). Individual participant data were pooled from 2 retrospective cohorts: 1) The Moli-LOCK cohort consists of 1,501 adults, a portion of the larger Moli-sani Study (n=24,325; 2005-2010) who were administered a phone-based questionnaire to assess lifestyles and psychological factors during confinement; 2) the ALT RISCOVID-19 is a web-based survey of 1,491 individuals distributed throughout Italy who self-responded to the same questionnaire by using Google forms.UPF was defined according to NOVA classification based on degree of food processing. An UPF score was created by assigning 1 point to increased consumption, -1 to decreased and 0 point for unchanged intakes of 19 food items, with higher values indicating an increase in UPF during confinement. Overall, 37.5% of the population reported some increase in UPF (UPF score ≥1). Adults were more likely to decrease UPF (multivariable regression coefficient β=-1.94; 95%CI: -2.72,-1.17 for individuals aged >75 y as compared to 18-39 y) as did individuals from southern Italian regions as compared to Northern inhabitants (β=-1.32; -1.80,-0.84), while UPF lowering associated with increased exercise (β=-0.90; -1.46,-0.35) and weight loss (β=-1.05; -1.51, -0.59) during confinement. During the first Italian lockdown, about 40% of our population switched to unfavourable eating as reflected by increased UPF intake and this may have long-term effects for health.
