Prevalence of overweight and obesity in preschool children in Thessaloniki, Greece.

Data on obesity in preschoolers are scarce in Greece, a country particularly affected by the obesity epidemic. The present study aimed to assess overweight and obesity prevalence of preschoolers in Thessaloniki, Greece, by using three different standards for defining childhood overweight and obesity

Diet quality, overweight and daily monetary allowance of Greek adolescents.

Objective: To investigate cross-correlates of pocket-money on diet quality and weight status of Greek adolescents. Methods: A total of 172 adolescents (55.2% boys), aged between 10 and 15 years old were recruited. Body weight and height were measured, body mass index (BMI) was computed. Weight status was assessed according to the International Obesity Task Force criteria and diet quality was evaluated via the Healthy Eating Index (HEI) - 2010. Results: Adolescents were allowed a mean allowance of €4.63 ± 3.66 daily. Among boys participants, BMI correlated with pocket money (r = 0.311, p ≤ 0.002) and normoweight boys received statistically less money than their overweight peers (p ≤ 0.019). In both sexes, normoweight was more prevalent in the lowest monetary quartiles. Pocket money was not associated with HEI. Among boys, moderate HEI was more prevalent in the third quartile of pocket money, significantly higher compared to all others (p ≤ 0.01 for all). For girls, the prevalence of moderate HEI declined by each ascending pocket money quartile (p ≤ 0.05 for all). Conclusion: In our sample, adolescents exhibited high rates of pooled overweight including obesity. The majority of the participants followed a diet of moderate quality. Pocket money was associated with BMI only among boys. As pocket money was not associated with diet quality, it is highly possible that adolescents might choose to spend their money on items other than foods. Our study shows that pocket money should be controlled during adolescence and teenagers should be educated on spending their money on healthier food choices

Estimating the volatility of cryptocurrencies during bearish markets by employing GARCH models

This study examines the volatility of certain cryptocurrencies and how they are influenced by the three highest capitalization digital currencies, namely the Bitcoin, the Ethereum and the Ripple. We use daily data for the period 1 January 2018–16 September 2018, which represents the bearish market of cryptocurrencies. The impact of the decline of these three cryptocurrencies on the returns of the other virtual currencies is examined with models of the ARCH and GARCH family, as well as the DCC-GARCH. The main conclusion of the study is that the majority of cryptocurrencies are complementary with Bitcoin, Ethereum and Ripple and that no hedging abilities exist among principal digital currencies in distressed times. © 2019 The Author(s

Growth, the Mediterranean diet and the buying power of adolescents in Greece

The aim of the present cross-sectional study was to evaluate associations between pocket money, Mediterranean diet (MD) adherence and growth among Greek adolescents. A total of 319 (157 boys and 162 girls) Greek adolescents, aged 10-18 years participated in the study. Pocket money was recorded, MD adherence was assessed with the KIDMED score and growth was evaluated using the World Health Organization (WHO) growth charts. Participants receiving pocket money exceeding 6.0€ daily demonstrated increased fast-food consumption and breakfast skipping. Overall, a negative relationship was revealed between pocket money and obesity. However, lower allowance receivers were less likely to be obese, consume fruit per day and more likely to consume breakfast and sweets, compared to average pocket money receivers. Increased MD adherence was associated with a lower risk of overweight and as expected, unhealthy eating habits were observed among obese adolescents. Interrelationships tend to exist between MD adherence, pocket money and growth among adolescents. © 2018 Walter de Gruyter GmbH, Berlin/Boston

Human T-lymphotropic virus type I/II infections in volunteer blood donors from Northern and Western Greece: Increased prevalence in one blood bank unit

Blood donors are routinely screened for antibodies to human T-cell lymphotropic viruses type I and II (HTLV-I and HTLV-II) in the United States, Canada, Japan, and some European countries. Previous reports from our group in relatively small numbers of donors have shown a zero prevalence of HTLV-I/II markers in our region. In this study, seven blood banks in the north and west of Greece participated in order to determine whether mandatory screening of blood donations for HTLV-I/II infection should be established. Sera from 51,714 consecutive donors were investigated for anti-HTLV-I/II using two commercially available enzyme immunoassays (EIAs). Reactive samples in one or both EIAs were repeatedly evaluated further by Western blot, which is specific for both confirmation and differentiation of HTLV-I and HTLV-II seroreactivities. Investigation for HTLV DNA was also done in all EIA-reactive donors, irrespective of the WB result, using a combination assay based on the polymerase chain reaction (PCR) and a DNA EIA. A total of 115 donors (0.222%; 95% CI 0.018-0.26%) were initially considered reactive for anti-HTLV-I/II by EIAs. However, only 7 of the 115 were confirmed as positive by WB (five HTLV-I and two HTLV-I/II). Thus, the prevalence of anti-HTLV-I/II in donors from northern and western Greece was 0.013% (95% CI 0.003-0.023%). Interestingly, the majority of WB-confirmed anti-HTLV-positive individuals were detected in the blood bank of Corfu (5/7, all anti-HTLV-I). This prevalence (5/15383; 0.032%; 95% CI 0.004-0.061%) was six times the prevalence found at the other blood banks combined (2/36331; 0.0055%; 95% CI 0-0.013%), but it was not statistically significant. None of the EIA-reactive donors had detectable HTLV DNA. The very low prevalence of confirmed anti-HTLV-I/II infection markers in northern and western Greek blood donors, together with the negative PCR results in EIA-reactive subjects, indicates that anti-HTLV-I/I routine screening is not really justified in this area of our country. However, the increased prevalence of WB-confirmed anti-HTLV-I-positive donors in the Corfu blood bank calls for further prospective and careful investigation in order to address whether this finding represents a real cluster phenomenon of HTLV infection. © 2004 Elsevier B.V.

Development and validation of a novel paediatric weight estimation equation in multinational cohorts of sick children

Aim: In sick children who are unable to be weighed estimation of weight is often required, but the routinely used equations lack accuracy and precision. This study aimed to develop a novel equation (Children's European Estimator of Weight-CEEW) using measurements of mid-upper arm circumference (MUAC) and other predictors in multinational groups of sick children in Europe. Methods: Weight estimation equations were developed in 2086 children from the UK, Greece and the Netherlands, using a combination of demographics, MUAC and height measurements. The final CEEW equations were compared against the performance of the European Resuscitation Council (ERC), Advanced Paediatric Life Support (APLS) and the Cattermole equations. Results: Two final CEEW equations were developed, incorporating measurements of age, gender and MUAC, with (CEEW1) or without (CEEW2) the inclusion of height. Both equations presented very high coefficients of determination (R2 >96.5%), minimal mean prediction error and narrower limits of agreement than the comparator equations. 88% (CEEW1) and 77% (CEEW2) of weight estimates fell within 15% of measured body weight. These figures compared with less than 57%, 57% and 37% for the ERC, APLS and Cattermole equations respectively. Conclusion: The CEEW equations performed substantially better than other routinely used equations for weight estimation. An electronic application for mobile use is presented

The correlation of right 2D:4D finger length ratio to the low-grade inflammation marker IL-6 in children: The healthy growth study

Background: Second to fourth digit ratio (2D:4D) is associated with cardiometabolic risk in adults. Aim: To examine the association of right 2D:4D with cardiovascular disease risk factors in children. Study design: Cross-sectional study. Subjects: A sample of 301 children (53.5% girls) aged 9-13 in Greece and their parents. Children who were sick during the previous week of examination (n = 44) were excluded from the analyses. Outcome measures: Socio-demographic (gestational age, birth weight, age, gender, maternal education level), anthropometric (body weight and height, finger length), clinical (pubertal stage, sickness during the previous week of the examination), blood [serum high sensitivity C-reactive protein (CRP), serum high sensitivity interleukin-6 (IL-6), serum leptin], lifestyle (dietary intake, maternal smoking during pregnancy) and physical fitness (handgrip strength) data were collected. CRP, IL-6 and leptin were measured with ELISA, using standard equipment and procedures, in accordance with manufacturers' instructions. Results: Full data were available for 257 children (52.1% girls). The rank values of right 2D:4D and IL-6 were included in the analyses. Right 2D:4D was correlated only with IL-6 at a bivariate level (r = 0.216, p = 0.012) in girls. At a linear multivariate level, this association remained significant, even after adjusting for several potential confounders such as age, Tanner stage, maternal education level, body mass index, maternal smoking during pregnancy, duration of pregnancy, protein-, carbohydrate-, fat-intake and physical fitness (β ± SE = 0.220 ± 0.066, p = 0.001). Conclusions: Right 2D:4D was found to be associated with IL-6 in girls. Right 2D:4D may be a valuable, simple screening tool of low-grade inflammation in children. © 2013 Elsevier Ltd

Frequency and quantity of egg intake is not associated with dyslipidemia: The hellenic national nutrition and health survey (HNNHS)

Background: Gaps remain on the safety of egg intake on cardiovascular health, setting the study’s aim to investigate the association between quantity and frequency of egg consumption, with established dyslipidemia. Methods: Study participants (N = 3558, 40.3% males) included individuals from the Hellenic National and Nutrition Health Survey (HNNHS), of national representation. Quantity and frequency of egg consumption was determined. Minimally adjusted, multivariable logistic and linear analysis were used to assess egg consumption and dyslipidemia. Results: The more frequent egg consumption compared to no or rare egg consumption significantly decreased the odds of dyslipidemia in the minimally adjusted (Odds Ratio (OR) for frequency: 0.83; 95% Confidence Interval (CI): 0.752, 0.904; OR for quantified frequency: 0.87; 95% CI: 0.796, 0.963) and the fully adjusted models (OR for frequency: 0.80; 95% CI: 0.718, 0.887; OR for quantified frequency: 0.85; 95%CI: 0.759, 0.945). Level of serum cholesterol and LDL-c were significantly lower with higher frequency and quantified frequency of egg consumption in all models. Conclusion: Eggs do not increase the risk of dyslipidemia and can be consumed as part of a healthy diet that is high in fiber and low in saturated fat, without excessive energy intake, by all individuals. © 2019 by the authors.
