Background The present study aimed to examine how different meal and snack patterns are associated with micronutrient intakes and diet quality among a nationally representative sample of Greek children and adolescents aged 1-19 years from the cross-sectional Hellenic National Nutrition and Health Survey (n = 598). Methods Meal and snack patterns were derived using 24-h dietary recalls. Mean adequacy ratio (MAR) was used as an overall measure of diet quality. Multiple linear regression adjusted for covariates was conducted to examine associations between eating patterns, nutrient intakes and MAR. Results Four most frequently reported eating schemes were identified including breakfast (B), lunch (L), dinner (D) and two snacks (S) (20.9%); B, L, D and 1S (16.2%); B, L, D and 3S (10.8%); and B, L and D (7.9%). Based on these schemes, the daily consumption of all main meals from the majority of the sample was highlighted. In children and adolescents aged 4-19 years, increasing snack frequency was positively associated with intakes of vitamin D, vitamin K, riboflavin, niacin, pantothenic acid, folate, magnesium, copper and selenium. An inverse association was recorded for vitamin E, vitamin B6 , calcium and iron. Among children aged 1-3 years, only niacin and copper were significantly associated with number of snacks, with the group of 'B-L-D-2S' presenting the highest intake. As for the overall diet quality, among all participants, there was no significant association of MAR with the type of meal and snack pattern, and thus the snack frequency. Conclusions Snacking behaviour is a common practice among children and adolescents. Modifying current snack foods with nutrient-rich choices could lead to an improvement of their diet's nutritional quality.

Background and aims: Empirically-derived dietary patterns have been shown to have both positive and adverse associations with cardiovascular disease (CVD). Yet, such associations remain unclear in the Greek population. The aim of this study was to investigate the association between empirically-derived dietary patterns and the presence of CVD and CVD-related medical conditions in a nationally representative sample of Greek adults. Methods and results: Adult participants (≥20 years old) of the Hellenic National Nutrition and Health Survey (HNNHS) were included (N = 3552; 41.2% men; 43.7 years, SD: 18.1). Dietary patterns were derived by principal component analysis using 24-h recall data. The presence of dyslipidemia (elevated cholesterol and/or triglycerides), hypertension, coronary heart disease, and total CVD, was defined according to the International Clinical Diagnosis (ICD)-10 codes. Odds ratios of CVD outcomes were estimated across dietary patterns using multivariable logistic regression analysis. Three dietary patterns -Traditional (proxy Mediterranean), Western, and Prudent-were identified explaining 16.5% of the total variance in consumption. Logistic regression analysis, adjusted for age, sex, total caloric intake, sociodemographic characteristics, and other CVD risk factors, showed an inverse association between the Traditional dietary pattern and CVD presence (OR: 0.53; 95% CI: 0.30–0.95), and a positive association between the Western pattern and dyslipidemia (1.52; 1.02–2.26). No association was found between the Prudent pattern and CVD outcomes. Conclusion: The variability of food intake combinations in the Greek population seem to be associated with the presence of CVD and CVD related conditions. Such findings are imperative for national monitoring and informed priority setting. © 2019 The Italian Society of Diabetology, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition, and the Department of Clinical Medicine and Surgery, Federico II University

Background The aim of the Hellenic National Nutrition and Health Survey was to assess nutritional intake, health status and various behaviors in a representative sample of the Greek population. Methods Data collection took place from 01.09.2013 to 31.05.2015. Random stratified sampling was performed by (a) geographical density criteria of Greece (7 regions), (b) age group of the reference population ( 65 years) and (c) gender distribution. The final population enrolled included (throughout Greece), 4574 individuals (42.5% men; 57.5% women of who 47.2% were from Athens metropolitan area, 18.5% from Central Macedonia, and the remaining 34% almost equally scattered throughout the country (p for the comparisons with official statistics by region, age group and sex > 0.7). Questionnaires developed were based on extensive review of the literature, following a validation procedure when necessary. Results Preliminary analyses revealed that 32% of the adult population were overweight and 15.5% were obese, with significant gender differences in total and per age group (p

Background & aims: Serum 25(OH)D deficiency is becoming an epidemic. The aim was to assess vitamin D status of the adult Greek population in relation to intake, sun exposure and other factors, using data from the Hellenic National Nutrition and Health Survey (HNNHS). Methods: Data from 1084 adult participants (37.8% males) were analyzed. Vitamin D intake was assessed using 24-h recalls. Serum 25(OH)D concentration was evaluated and related to anthropometric measurements and other covariates including supplements used, by sex. Variables significantly associated with 25(OH)D < 20 ng/ml were assessed using simple and multiple logistic regression. Results: Median vitamin D intake from food was 1.23 mcg/day (0.60, 2.44), with 9.1% consuming supplements. Median serum 25(OH)D was 16.72 ng/ml, with no sex differences (P = 0.923). The odds of having 25(OH)D < 20 ng/ml significantly decreased with being very active (OR 0.55, 95% CI 0.35, 0.98), increasing length of sun exposure [1–3 h/day (OR 0.59, 95% CI 0.44, 0.80), >3 h/day (OR 0.36, 95% CI 0.24, 0.55)], and skin colour [light to medium skin (OR 0.47, 95% CI 0.24, 0.91), fairly dark skin colour (OR 0.34, 95% CI 0.17, 0.67) and dark or very dark skin colour (OR 0.34, 95% CI 0.15, 0.75)], compared to respective baseline levels. The odds significantly increased with obesity (OR 1.95, 95% CI 1.24, 3.08), and spring season of blood sample collection (OR 1.75, 95% CI 1.22, 2.50). Conclusions: Vitamin D deficiency is highly prevalent in Greek adults. Relevant public health policies are highly recommended, which could include vitamin D fortification. and suggestion for increased but safe sun exposure. © 2019 European Society for Clinical Nutrition and Metabolism

Objectives: The objective of this study was to identify and describe different dietary patterns in a nationally representative sample of Greek adults and to assess potential associations with lifestyle characteristics. Study design: This was a cross-sectional study. Methods: Dietary patterns were derived by principal component analysis using individual dietary data (24-h recall) of 3552 participants of the Hellenic National Nutrition and Health Survey (HNNHS). Analysis of variance and chi-squared test were used to determine the lifestyle characteristics of the participants following each pattern. Results: Three dietary patterns were identified explaining 16.5% of variance; a traditional pattern, loading positively on olive oil, non-starchy vegetables, and cheese; a Western pattern, loading positively on refined grains, processed meats, and animal fats; and a prudent pattern, loading positively on fruits, whole grains, and yoghurt and negatively on fast food. A fourth, snack-type pattern, loading positively on sweets, salty snacks, and nuts, was identified in women. Primary crude results revealed an association between dietary patterns and socio-economic status. In multivariate analysis, highest adherence to the prudent pattern was associated with higher protein and unsaturated fat intake and lower energy and saturated fat intake (all P ≤ 0.05); the Western and traditional patterns were associated with higher energy and total and saturated fat intake. The traditional pattern was additionally associated with higher monounsaturated fatty acids intake, whereas the Western pattern, with higher alcohol intake (all P ≤ 0.001). Conclusions: These findings are valuable for understanding the dietary behaviors of adults in Greece and enabling more focused public health policies for the promotion of healthier food behaviors in the future. © 2019 The Royal Society for Public Health
