ABSTRACT

BACKGROUND AND AIMS: Increasing literature data show that adherence to the Mediterranean diet is undergoing profound changes in recent years, albeit with marked differences across nations. In Italy, one of the cradles of the Mediterranean diet, the literature regarding the trend for Mediterranean diet adherence is conflicting. Thus, we aimed to explore the trends of adherence to the Mediterranean diet in a large cohort of participants living in South Italy, over 20 years from 1985-86 to 2005-06. METHODS AND RESULTS: Cross-sectional study with two evaluations, one made in 1985-86 and another in 2005-06; all participants were adults aged 30-70 years of age. The adherence to the Mediterranean diet was evaluated using the score proposed by Panagiotakos et al. This score features values ranging from 0 to 55, higher scores reflecting a greater adherence. The data are reported by age (30-49 vs. 50-69 years). Overall, 2451 subjects were included in 1985-86 and 2375 in 2005-06. A significant reduction was observed in the adherence to the Mediterranean diet (age 30-49 years: 31.82 ± 4.18 in 1985-86 vs. 29.20 ± 4.48 in 2005-06, reduction by 8.2%, p < 0.0001; age 50-69: 32.20 ± 4.09 in 1985-86 vs.30.15 ± 4.27 in 2005-06, reduction by 6.3%, p < 0.0001). Among all these items, the most dramatic change was observed for olive oil consumption, that decreased by 2.35 points in younger and 0.89 in older people. CONCLUSION: The adherence to the Mediterranean diet decreased from 1985-86 to 2005-06 in South Italy, particularly in younger people, above all due to a decreased olive oil consumption.

ABSTRACT

Non-alcoholic fatty liver disease (NAFLD) is a common condition in Western countries. However, their metabolic characteristics are poorly known even though they could be important. Therefore, the objective of this study was to measure resting metabolic parameters in overweight/obese adults with hepatic steatosis compared to controls, matched for age, sex, and obesity level. Hepatic steatosis was diagnosed with liver ultrasound. Energy metabolism was measured with indirect calorimetry: energy expenditure (REE), predicted REE, the ratio between REE and the predicted REE, and the respiratory quotient (RQ) were reported. We measured some anthropometric, body composition, and bio-humoral parameters; 301 participants with NAFLD were matched for age, sex, and obesity level with 301 participants without NAFLD. People with NAFLD showed significantly higher REE (1523 ± 238 vs. 1464 ± 212 kcal, p = 0.005), REE/REE predicted ratio (98.2 ± 9.4 vs. 95.7 ± 8.1, p = 0.002), and RQ (0.88 ± 0.08 vs. 0.85 ± 0.07, p = 0.03). Moreover, the NAFLD group had significantly higher inflammatory and insulin-resistance parameters compared to controls. In conclusion, NAFLD is associated with a significantly higher metabolic expenditure, as measured with indirect calorimetry, compared to a similar cohort of individuals without this condition. Higher inflammatory levels in patients with NAFLD can probably explain our findings, even if other research is needed on this issue.

ABSTRACT

OBJECTIVE: Alcoholic fatty liver (AFLD) and non-alcoholic fatty liver (NAFLD) are two common conditions. However, if they can increase the risk of death is poorly explored. We therefore aimed to investigate the potential association between the presence and severity of liver steatosis and mortality in a large sample of older people. DESIGN: Prospective. SETTING: Community. PARTICIPANTS: Women and men randomly sampled from the electoral rolls of the population of Castellana Grotte, a town in Southern Italy (Apulia region) between 2005 and 2006. Among 1942 initially contacted, 1708 (=87.9%) participated to the baseline survey (Multicentrica Colelitiasi III (MICOL III)). This specific study included 1445 older participants (mean age=65.2 years, females=44.2%). EXPOSURE: NAFLD or AFLD. PRIMARY AND SECONDARY OUTCOMES: Mortality (all-cause and specific-cause). RESULTS: After a median of 12 years, 312 participants (=21.6%) died. After adjusting for nine potential confounders, the presence of steatosis was not associated with any increased risk of death in both NAFLD and AFLD. The severity of liver steatosis was not associated with any increased risk of mortality in NAFLD, while in AFLD, the presence of moderate steatosis significantly increased the risk of overall (HR=2.16; 95% CI 1.19 to 3.91) and cancer-specific (HR=3.54; 95% CI 1.16 to 10.87) death. CONCLUSIONS: Liver steatosis is not associated with any increased risk of death in NAFLD, while moderate steatosis could be a risk factor for mortality (particularly due to cancer) in people affected by AFLD.

ABSTRACT

OBJECTIVES: In the postmenopausal period, most women suffer vasomotor symptoms (VMS). It is well-known that VMS can worsen the quality of life. Diet seems to play a relevant role in the development of VMS, but the effect of diet on VMS is mainly limited to observational studies, and analyses of nutritional supplements. The aim of this study was thus to determine the efficacy of a lactoovo- vegetarian (LOVe) diet rich in omega-3 fatty acids vs. a lacto-ovo-vegetarian diet rich in EVO (extra-virgin olive oil) in reducing VMS frequency in postmenopausal women. METHODS: A two-arms (lacto-ovo-vegetarian diet with EVO vs. lacto-ovo-vegetarian diet rich in omega-3) randomized-controlled trial with a follow-up period of 16 weeks. We considered as primary outcome the change in the Kupperman index (follow-up vs. baseline evaluation, reported as delta, D) and in its subscales. Secondary outcomes included changes in common anthropometric and biohumoral measurements. RESULTS: Among 54 women randomly assigned to a study group, 40 (mean age 55.1±5.4 years) completed the study and complied with their assigned diet. Women randomized to the omega-3 group (n=18) showed significant improvements, compared to the EVO group (n=22), in Kupperman index (Δ=-11.4±9.8 vs. -5.9±8.2; p=0.045), hot flashes (Δ=-3.3±3.4 vs. -1.3±2.6; p=0.04), and a marginally significant improvement in nervousness (Δ=-1.7±1.7 vs. -0.8±1.5; p=0.07). No significant differences were observed for the secondary outcomes. No relevant side effects were reported. CONCLUSION: After 16 weeks, a lacto-ovo-vegetarian diet rich in omega-3 reduced VMS frequency in postmenopausal women more than the lacto-ovo-vegetarian diet rich in EVO.

ABSTRACT

BACKGROUND AND OBJECTIVE: Estrogens could protect the liver from fatty degeneration, but there is little information about whether menopause is associated with the severity of alcoholic (AFL) and non-alcoholic fatty liver (NAFL). Our aim was to evaluate the distribution of fatty liver detected by ultrasound in pre- and post-menopausal women and the factors associated with these conditions. METHODS: In this cross-sectional study, the years from menopause were investigated through selfreported information. The degree of fatty liver was assessed through a standardized ultrasound examination (scores 0 to 6, higher values reflecting a greater severity). Liver steatosis was classified as NAFL or AFL based on a daily alcohol intake > 20g/d. RESULTS: The study included 752 women in menopause and 535 in pre-menopause. The years from menopause were not associated with the severity of liver steatosis in NAFL (p for trend=0.74; Spearman correlation=0.04; 95%CI: -0.09 to 0.17), whereas all the indexes of adiposity and the number of metabolic syndrome factors were associated with a higher liver steatosis score. Taking AFL liver steatosis as the outcome, the years since menopause were not significantly associated with liver steatosis in AFL (p for trend=0.50; Spearman correlation=0.09; 95%CI: -0.17 to 0.34), whilst the association between anthropometric parameters and liver steatosis severity resulted stronger in postmenopausal compared to pre- menopausal women. CONCLUSION: the higher prevalence of fatty liver observed in post-menopausal women is probably not due to menopause per se, but to the adiposity (particularly abdominal) typical of this age and its consequences (such as metabolic syndrome).

ABSTRACT

Coffee drinking seems to have several beneficial effects on health outcomes. However, the effect on hepatic steatosis, depending on a high alcohol consumption (AFLD, alcoholic fatty liver disease) or on metabolic factors (non-alcoholic fatty liver disease, NAFLD), is still equivocal. Thus, we aimed to explore the potential association between coffee consumption and the presence and severity of hepatic steatosis in people with NAFLD or AFLD. In this cross-sectional study, coffee drinking was recorded using a semi-quantitative food frequency questionnaire, and categorized as yes vs. no and as 0, 1, 2, ≥3. The degree of fatty liver was assessed through a standardized ultrasound examination (score 0 to 6, with higher values reflecting higher severity). Liver steatosis was classified as NAFLD or AFLD on daily alcohol intake >30 g/day for men and >20 g/day for women. This study included 2819 middle-aged participants; the great majority were coffee drinkers (86.1%). After adjusting for 12 potential confounders, drinking coffee was not associated with decreased odds for NAFLD (n = 916) (odds ratio, OR = 0.93; 95% confidence intervals, CI: 0.72-1.20) or AFLD (n = 276) (OR = 1.20; 95% CI: 0.66-2.0). The consumption of coffee (categorized as yes vs. no), or an increased consumption of coffee were not associated with the presence of mild, moderate or severe liver steatosis in either NAFLD or AFLD. In conclusion, coffee intake was not associated with any lower odds of hepatic steatosis in either non-alcoholic or alcoholic forms in this large cohort of South Italian individuals.

ABSTRACT

AIM: To investigate the prevalence of undernutrition, risk of malnutrition and obesity in the Italian gastroenterological population. METHODS: The Italian Hospital Gastroenterology Association conducted an observational, cross-sectional multicenter study. Weight, weight loss, and body mass index were evaluated. Undernutrition was defined as unintentional weight loss > 10% in the last three-six months. Values of Malnutrition Universal Screening Tool (MUST) > 2, NRS-2002 > 3, and Mini Nutritional Assessment (MNA) from 17 to 25 identified risk of malnutrition in outpatients, inpatients and elderly patients, respectively. A body mass index ≥ 30 indicated obesity. Gastrointestinal pathologies were categorized into acute, chronic and neoplastic diseases. RESULTS: A total of 513 patients participated in the study. The prevalence of undernutrition was 4.6% in outpatients and 19.6% in inpatients. Moreover, undernutrition was present in 4.3% of the gastrointestinal patients with chronic disease, 11.0% of those with acute disease, and 17.6% of those with cancer. The risk of malnutrition increased progressively and significantly in chronic, acute and neoplastic gastrointestinal diseases in inpatients and the elderly population. Logistical regression analysis confirmed that cancer was a risk factor for undernutrition (OR = 2.7; 95%CI: 1.2-6.44, P = 0.02). Obesity and overweight were more frequent in outpatients. CONCLUSION: More than 63% of outpatients and 80% of inpatients in gastroenterological centers suffered from significant changes in body composition and required specific nutritional competence and treatment.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate the distribution of fatty liver-nonalcoholic (NAFL) and alcoholic (AFL)-and its association with metabolic syndrome and its components in a population sample from a Mediterranean area. METHODS: A sample of 2974 subjects (1679 males, 1295 females, age range 30-89 years) was randomly drawn from the population of a town in southern Italy. The survey visit included a validated semiquantitative food frequency questionnaire, anthropometric measurements, a blood sample taken in the morning after overnight fasting, as well as abdominal ultrasound examination to evaluate liver fat with a standardized scoring system. The 2001 National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) definition of the metabolic syndrome was adopted. RESULTS: In this Mediterranean population, where alcohol intake is mostly as wine with meals, NAFL is present in 36.8% of men and 25.7% of women and AFL in 13.8% of men and 5.5% of women. NAFL and AFL are associated with metabolic syndrome and its characteristics, body mass index (BMI), and visceral and subcutaneous fat (in AFL subjects, only in women) measured by ultrasound. Stratifying by BMI and controlling for confounders (age, height, smoking habit, and alcohol consumption), in overweight and obese subjects, liver and visceral fat are associated with the metabolic syndrome both in men and women and subcutaneous fat only in women. In normal weight subjects, only liver fat in men is associated with the metabolic syndrome. CONCLUSIONS: Fatty liver is highly prevalent in this Mediterranean population and is associated with metabolic syndrome in overweight and obese men and women as well as in men with normal BMI.
