Dietary intake of vitamin C and gastric cancer: a pooled analysis within the Stomach cancer Pooling (StoP) Project

BACKGROUND

Previous studies suggest that dietary vitamin C is inversely associated with gastric cancer (GC), but most of them did not consider intake of fruit and vegetables. Thus, we aimed to evaluate this association within the Stomach cancer Pooling (StoP) Project, a consortium of epidemiological studies on GC.

METHODS

Fourteen case-control studies were included in the analysis (5362 cases, 11,497 controls). We estimated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the association between dietary intake of vitamin C and GC, adjusted for relevant confounders and for intake of fruit and vegetables. The dose-response relationship was evaluated using mixed-effects logistic models with second-order fractional polynomials.

RESULTS

Individuals in the highest quartile of dietary vitamin C intake had reduced odds of GC compared with those in the lowest quartile (OR: 0.64; 95% CI: 0.58, 0.72). Additional adjustment for fruit and vegetables intake led to an OR of 0.85 (95% CI: 0.73, 0.98). A significant inverse association was observed for noncardia GC, as well as for both intestinal and diffuse types of the disease. The results of the dose-response analysis showed decreasing ORs of GC up to 150-200 mg/day of vitamin C (OR: 0.54; 95% CI: 0.41, 0.71), whereas ORs for higher intakes were close to 1.0.

CONCLUSIONS

The findings of our pooled study suggest that vitamin C is inversely associated with GC, with a potentially beneficial effect also for intakes above the currently recommended daily intake (90 mg for men and 75 mg for women).

Reproductive factors, hormonal interventions, and gastric cancer risk in the Stomach cancer Pooling (StoP) Project

BACKGROUND

Gastric cancer incidence is higher in men, and a protective hormone-related effect in women is postulated. We aimed to investigate and quantify the relationship in the Stomach cancer Pooling (StoP) Project consortium.

METHODS

A total of 2,084 cases and 7,102 controls from 11 studies in seven countries were included. Summary odds ratios (ORs) and 95% confidence intervals (CIs) assessing associations of key reproductive factors and menopausal hormone therapy (MHT) with gastric cancer were estimated by pooling study-specific ORs using random-effects meta-analysis.

RESULTS

A duration of fertility of ≥ 40 years (vs. < 20), was associated with a 25% lower risk of gastric cancer (OR = 0.75; 95% CI: 0.58-0.96). Compared with never use, ever, 5-9 years and ≥ 10 years use of MHT in postmenopausal women, showed ORs of 0.73 (95% CI: 0.58-0.92), 0.53 (95% CI: 0.34-0.84) and 0.71 (95% CI: 0.50-1.00), respectively. The associations were generally similar for anatomical and histologic subtypes.

CONCLUSION

Our results support the hypothesis that reproductive factors and MHT use may lower the risk of gastric cancer in women, regardless of anatomical or histologic subtypes. Given the variation in hormones over the lifespan, studies should address their effects in premenopausal and postmenopausal women. Furthermore, mechanistic studies may inform potential biological processes.

Perceptions and educational needs of social and healthcare professionals in the prevention of domestic violence - A focus group study

OBJECTIVE

To explore and describe social and healthcare professionals' perceptions and educational needs in relation to domestic violence and its prevention.

METHODS

A qualitative research was conducted in three European countries. Two multidisciplinary focus group interviews were conducted (in each country) among professionals and higher education teachers in the field of social and health care. Total number of participants were 32 (Finland n=12, Greece n=12, Portugal n=8). The transcribed data were analyzed by thematic analysis.

RESULTS

Participants' perceptions of domestic violence and its prevention included: multidimensional phenomenon, consequences, and addressing concern. Domestic violence was seen as a multidimensional phenomenon, which has various consequences for several aspects of life. Professionals have difficulties addressing their concern due to lack of knowledge and tools. Solutions to prevent domestic violence that the participants shared were: education, intervention, and strategies. Education was seen as the key aspect for the prevention of domestic violence. Also, professionals' communication and situation management skills, as well as national and international strategies, were seen as valuable solutions. Educational needs for prevention of domestic violence were expressed based on content, methods, and practices, such as services system and legislation.

CONCLUSION

The findings of the current study highlight the social- and healthcare professionals' need for education about domestic violence. It is essential that these professionals receive appropriate training to effectively identify and address domestic violence. The current study provides useful information for the development of relevant training/education for this group of professionals.

Diagnostic accuracy of HPV16 early antigen serology for HPV-driven oropharyngeal cancer is independent of age and sex

A growing proportion of head and neck cancer (HNC), especially oropharyngeal cancer (OPC), is caused by human papillomavirus (HPV). There are several markers for HPV-driven HNC, one being HPV early antigen serology. We aimed to investigate the diagnostic accuracy of HPV serology and its performance across patient characteristics. Data from the VOYAGER consortium was used, which comprises five studies on HNC from North America and Europe. Diagnostic accuracy, that is, sensitivity, specificity, Cohen's kappa and correctly classified proportions of HPV16 E6 serology, was assessed for OPC and other HNC using p16INK4a immunohistochemistry (p16), HPV in situ hybridization (ISH) and HPV PCR as reference methods. Stratified analyses were performed for variables including age, sex, smoking and alcohol use, to test the robustness of diagnostic accuracy. A risk-factor analysis based on serology was conducted, comparing HPV-driven to non-HPV-driven OPC. Overall, HPV serology had a sensitivity of 86.8% (95% CI 85.1-88.3) and specificity of 91.2% (95% CI 88.6-93.4) for HPV-driven OPC using p16 as a reference method. In stratified analyses, diagnostic accuracy remained consistent across sex and different age groups. Sensitivity was lower for heavy smokers (77.7%), OPC without lymph node involvement (74.4%) and the ARCAGE study (66.7%), while specificity decreased for cases with <10 pack-years (72.1%). The risk-factor model included study, year of diagnosis, age, sex, BMI, alcohol use, pack-years, TNM-T and TNM-N stage. HPV serology is a robust biomarker for HPV-driven OPC, and its diagnostic accuracy is independent of age and sex. Future research is suggested on the influence of smoking on HPV antibody levels.

Palliative Care in the Community: The Greek Version of the Supportive and Palliative Care Indicators Tool (SPICT™)

INTRODUCTION/OBJECTIVES

Systematic identification of persons with palliative care needs constitutes a major challenge for promoting palliative care in all levels of the health system, including primary care. The aim of this study was to translate, cross-culturally adapt, and content validate Supportive and Palliative Care Indicators Tool (SPICT) for use in the Greek primary care context. Secondary objectives were to probe the use of SPICT-GR in exemplary case vignettes, to discuss the clarity and comprehensibility of its content as well as the appropriateness, acceptability, and feasibility of the tool within the Greek primary care.

METHODS

The Greek translation and cross-cultural adaptation of SPICT™ followed World Health Organization recommendations for translation and adaptation of instruments. For this purpose a working group was set up consisting of 2 senior researchers, a primary care professional with postgraduate training in Palliative Medicine and a general practitioner (GP) with special interest in primary palliative care. Three focus groups comprised of health professionals (n = 23) working in primary care settings participated in the pilot testing phase. Participants also completed a questionnaire including rating their perceptions on tool's utility and feasibility as well as on the clarity and relevance of its items. Thematic analysis was used for focus groups discussions on how the tool was perceived and interpreted by health professionals in a Greek healthcare context and descriptive statistics for the quantitative analysis of the questionnaire data.

RESULTS

The majority assessed the tool as useful (65%), considered its implementation in primary care as feasible (91%) and rated its items as "relevant" or "very relevant" and "clear" or "very clear." Three themes emerged from focus groups discussions: Guiding clinical practice and facilitating collaboration; promoting comprehensive care and awareness for palliative care; applicability in and suitability for primary care.

CONCLUSIONS

SPICT-GR™ was identified as a practical and applicable tool for primary care, a source of guidance for the comprehensive identification of patients' palliative care needs, promoting awareness on palliative care and facilitating a shared language among health care professionals.

The path between breakfast eating habit, sleep duration and physical activity on obesity status: An epidemiological study in schoolchildren

Background: Although the literature suggests that skipping breakfast, insufficient sleep, and reduced physical activity are associated with childhood obesity their co-influence and their in-between interactions on weight status have rarely been studied. Aim: To examine the co-influence of breakfast eating habits, sleep duration, and physical activity on the weight status of children 10-12 years old from several schools of Greece. Methods: A cross-sectional study was conducted on 1688 students in Greece, during 2014-2016. Children's Body Mass Index (BMI) was calculated and classified according to the International Obesity Task Force (IOTF) classification. Logistic regression models and path analysis were used. Results: Overweight/obesity prevalence was higher in boys (32.5% vs. 20.4%; p < 0.001). Average sleep duration decreased the odds of overweight/obesity [OR (95% CI): 0.86 (0.76, 0.97)] independently of the frequency of breakfast habit. Interaction between sleep duration with breakfast habit (p = 0.002) and physical activity (p < 0.001) was observed. Path analysis showed a negative association of BMI with sleep duration (standardized beta = -0.095, p < 0.001). A third-order interaction between breakfast habit, sleep duration, and physical activity revealed that daily breakfast eating along with adequate sleep and moderate/adequate physical activity levels, decreased the odds of over-weight/obesity by 55% [OR 0.45, 95% CI (0.27, 0.72)]. Conclusion: Although sleep duration is inversely associated with weight status independently of breakfast habit, the co-influence of adequate sleep duration with frequent breakfast eating and moderate/adequate physical activity seems to be a profoundly higher associated as a result of synergy against childhood obesity.

Nomophobia and Its Association with Depression, Anxiety and Stress (DASS Scale), among Young Adults in Greece

Smartphones with their numerous applications have become essential daily equipment, prompting scientific research to deal with the impact of their use on psychosocial health. Under this spectrum, the aim of the present cross-sectional study was to examine the association between nomophobia and the negative emotional states of depression, anxiety, and stress, in relation to self-esteem and sociodemographic data, among the young adult population. The study sample consisted of 1408 young adults aged 18-25 years, participating on a voluntary basis with an online anonymous questionnaire. Data were collected through the "Nomophobia Questionnaire (NMP-Q)", "Depression Anxiety Stress Scales-short form (DASS-21)", and Rosenberg Self-Esteem Scale (RSES). The questionnaire also included socio-demographic characteristics and smartphone use variables. Data analysis showed that women were identified with severe depression and stress to a greater extent than men (63.3% vs. 55.1% for depression and 18.1% vs. 13.8% for stress scale). With respect to nomophobia, participants with severe levels of nomophobia also exhibited severe levels of negative emotional states in all DASS components, i.e., 40.6% in depression, 73.7% in anxiety, and 32.7% in stress (all p values < 0.001). Participants with severe levels of depression and anxiety were very often checking their phone and used it in all daily activities. Moreover, correlation analysis revealed that self-esteem had a moderating effect on the relationship between nomophobia and DASS, a fact that modifies the association between the involved variables: stronger relationships appeared between nomophobia and DASS components in individuals with normal/high self-esteem than in individuals with low self-esteem.

Digital Health and Health Promotion: A Scoping Review of Systematic Reviews

INTRODUCTION AND METHODOLOGY

Health Promotion is moving into a new technological era, that of Digital Health Promotion (DHP). The aim was to collect systematic reviews of digital health promotion interventions.

RESULTS AND DISCUSSION

147 articles met the criteria and were included in the present study. A diverse range of digital health promotion topics was identified, with certain topics garnering significant attention. While this scoping review provides valuable insights into the field of digital health promotion interventions, a more detailed analysis of their alignment with health prevention stages will serve as a critical next step.

Perceptions and attitudes of people with severe mental disorders towards smoking in Greece

Despite its significant decline in the general population, smoking remains endemic and highly prevalent among people with mental disorders. The impact of smoking-attributable morbidity on life expectancy is significant since, in comparison to the general population, people with severe mental disorders have a 15-20-year reduction in life expectancy. A cross-sectional study was conducted among 1015 people with mental disorders through personal interviews. The questionnaire was designed to examine these patients' knowledge, perceptions, and attitudes towards smoking. Individuals were recruited from the mental health residential community services, the outpatient department, and the inpatient facilities of the Psychiatric Hospital of Attica. Statistical analysis was performed using SPSS 26.0. In the sample analyzed, the current-smoking prevalence stood at 68.4% (n=643), while 12.3% reported being former smokers. A staggering 86.3% smoked their first cigarette within 30 minutes of waking up, indicating a high level of dependence. Most of the former smokers (83.6%) reported that their main reason for quitting smoking was to improve their health, and the overwhelming majority (97.4%) had done so using no smoking cessation aid. Although slightly over half of the participants (53.7%) believed that health professionals adequately inform smokers about the harmful health effects of tobacco products, the information provided by health professionals on smoking cessation programs and tobacco harm reduction alternatives was considered sufficient by a mere 11.2%. Multiple logistic regression analysis demonstrated that outpatients tended to have a greater likelihood of being current smokers as compared to inpatients (OR=1.45), while users of mental health residential community services showed a significantly lower likelihood of being current smokers in comparison to inpatients (OR=0.49). Additionally, it was found that women had a lower likelihood of being current smokers compared to men (OR=0.51), while divorced/ widowed participants had a greater likelihood of being current smokers compared to single ones (OR=1.93). Finally, multiple regression analysis indicated that participants with psychotic disorders displayed a 2.39 times greater likelihood of being current smokers compared to those with mood disorders (OR=2.39). Understanding the knowledge, beliefs, and attitudes of people with mental disorders towards tobacco is an essential first step to confronting this neglected epidemic.

Protein Intake, Source and Effect on Children's Weight Status: An Epidemiological Study in Greece

The development of overweight and obesity during late childhood and early adolescence is one of the most critical issues in public health. Additionally, over the past few years, the consumption of protein has tended to increase in both children and adults. The present study aimed to evaluate whether the protein type, either plant- or animal-sourced, as well as the quantity consumed, could potentially have a relationship with excess body weight in children. A total of 47 primary schools were selected, and 1728 students, aged 10-12 years, were enrolled for the purposes of this study, leading to our final sample of 712. Physical measurements, such as weight and height, were measured, and children were separated into two weight status categories according to their Body Mass Index, which was obtained through the International Obesity Task Force criteria. Students' diets were assessed through a questionnaire, and total, plant- and animal-derived protein intakes were calculated. Unadjusted analysis showed a statistically significant association between body weight and plant protein. After adjustment for overall energy intake, sex, age, and exercise, there was a statistically significant negative association between plant protein and excess body weight in children (OR: 0.964, 95% CI: 0.936; 0.992), but a lack of association for animal-sourced protein (OR: 1.002, 95% CI: 0.991; 1.013). Dietary plant-derived protein seems to have a positive effect on weight status in children, independently of total energy intake and physical activity; nevertheless, additional research is required in order to elucidate the underlying mechanisms.

Implementation of risk enhancers in ASCVD risk estimation and hypolipidemic treatment eligibility: A sex-specific analysis

OBJECTIVE

Sex-specific data are limited regarding eligibility for hypolipidemic treatment. We aim to explore the sex-specific clinical utility of high-sensitivity C-reactive protein (hsCRP) and carotid ultrasound as risk modifiers for hypolipidemic treatment in primary prevention of atherosclerotic cardiovascular disease (ASCVD).

METHODS

We aimed to explore these sex-specific trends in two pooled contemporary independent Greek cohorts (Athens Vascular Registry n = 698, 50.9% women and Menopause Clinic n = 373, 100% women) of individuals without overt ASCVD. Baseline ASCVD risk was estimated using the Systematic COronary Risk Evaluation-2 (SCORE2) tools. The presence of carotid plaque and hsCRP ≥2 mg/L were integrated as risk modifiers.

RESULTS

Men had increased odds to achieve target LDL-C levels based on ASCVD risk (23.8% vs. 17.7%, OR: 1.45 95% CI: 1.05-2.00, p = 0.023, for men vs. women). Additionally, considering carotid plaque or high hsCRP levels did not change this association but reduced on-target LDL-C rate in both sexes. Women had decreased odds of being eligible for hypolipidemic treatment by ASCVD risk estimation (11.5% vs. 26.4%, p < 0.001) compared with men. The addition of carotid plaque presence or high hsCRP levels and their combination resulted in a higher relative increase in hypolipidemic treatment eligibility in women (from 11.5% to 70.9% vs. 26.4% to 61.4% for carotid plaque, from 11.5% to 38.5% vs. 26.4% to 50.8% for hsCRP and from 11.5% to 79.1% vs. 26.4% to 75% for their combination, all for women vs. men, pforinteraction < 0.001 for all) than men.

CONCLUSIONS

Implementation of carotid plaque and hsCRP levels increases hypolipidemic treatment eligibility more prominently in women than in men. The impact on clinical outcomes in these untreated patients merits further investigation.

Prevalence and Factors Related to Nomophobia: Arising Issues among Young Adults

Nomophobia is characterized as apprehension of being apart from smartphone, which causes the user to seek proximity with the device. The purpose of this study was to explore the prevalence and factors associated to nomophobia among young adults in Athens, the capital city of Greece. A cross-sectional study was performed on a sample of 1408 young adults aged 18-25 years. The questionnaire was anonymous, including the socio-demographic characteristics of the participants, the smartphone uses, and the nomophobia questions. Statistical analyses were done by simple univariable techniques or modeling the data through generalized linear models. Almost all participants (99.9%) exhibited any level of nomophobia, with the moderate level prevailing (57.0%). Women and non-working participants were more likely to exhibit severe nomophobia (adj PR = 1.57) and any level of nomophobia was 30% higher among the participants whose father had no academic degree (p = 0.029). In addition, 59% of those with severe nomophobia had very frequent phone checking (p < 0.001) while 45.8% with any level of nomophobia reported a negative influence on their academic performance. Attention should be paid to early prevention through the development of integrated health promotion programs.

Technologies in Home-Based Digital Rehabilitation: Scoping Review

BACKGROUND

Due to growing pressure on the health care system, a shift in rehabilitation to home settings is essential. However, efficient support for home-based rehabilitation is lacking. The COVID-19 pandemic has further exacerbated these challenges and has affected individuals and health care professionals during rehabilitation. Digital rehabilitation (DR) could support home-based rehabilitation. To develop and implement DR solutions that meet clients' needs and ease the growing pressure on the health care system, it is necessary to provide an overview of existing, relevant, and future solutions shaping the constantly evolving market of technologies for home-based DR.

OBJECTIVE

In this scoping review, we aimed to identify digital technologies for home-based DR, predict new or emerging DR trends, and report on the influences of the COVID-19 pandemic on DR.

METHODS

The scoping review followed the framework of Arksey and O'Malley, with improvements made by Levac et al. A literature search was performed in PubMed, Embase, CINAHL, PsycINFO, and the Cochrane Library. The search spanned January 2015 to January 2022. A bibliometric analysis was performed to provide an overview of the included references, and a co-occurrence analysis identified the technologies for home-based DR. A full-text analysis of all included reviews filtered the trends for home-based DR. A gray literature search supplemented the results of the review analysis and revealed the influences of the COVID-19 pandemic on the development of DR.

RESULTS

A total of 2437 records were included in the bibliometric analysis and 95 in the full-text analysis, and 40 records were included as a result of the gray literature search. Sensors, robotic devices, gamification, virtual and augmented reality, and digital and mobile apps are already used in home-based DR; however, artificial intelligence and machine learning, exoskeletons, and digital and mobile apps represent new and emerging trends. Advantages and disadvantages were displayed for all technologies. The COVID-19 pandemic has led to an increased use of digital technologies as remote approaches but has not led to the development of new technologies.

CONCLUSIONS

Multiple tools are available and implemented for home-based DR; however, some technologies face limitations in the application of home-based rehabilitation. However, artificial intelligence and machine learning could be instrumental in redesigning rehabilitation and addressing future challenges of the health care system, and the rehabilitation sector in particular. The results show the need for feasible and effective approaches to implement DR that meet clients' needs and adhere to framework conditions, regardless of exceptional situations such as the COVID-19 pandemic.

"DOMINO - Stop Domestic Violence". An Educational Mobile Application

Domestic violence affects people of all socioeconomic backgrounds and education levels and can happen to anyone. It is a public health issue that needs to be addressed with health and social care professionals playing an essential role in prevention and early intervention. These professionals need to be prepared through proper education. A European funded project developed "DOMINO - Stop domestic violence" educational mobile application which was piloted among 99 social and/or health care students and professionals. Most of the participants (n= 59, 59.6%) indicated that the DOMINO mobile application was easy to install and over half of them (n=61, 61.6%) would recommend the app. They found it easy to use, and quick access to useful materials and tools. Participants found case studies and the checklist good and useful tools for them. The DOMINO educational mobile application is available open access, in English, Finnish, Greek, Latvian, Portuguese and Swedish, for any stakeholder worldwide who is interested to learn more about domestic violence prevention and intervention.

A risk prediction model for head and neck cancers incorporating lifestyle factors, HPV serology and genetic markers

Head and neck cancer is often diagnosed late and prognosis for most head and neck cancer patients remains poor. To aid early detection, we developed a risk prediction model based on demographic and lifestyle risk factors, human papillomavirus (HPV) serological markers and genetic markers. A total of 10 126 head and neck cancer cases and 5254 controls from five North American and European studies were included. HPV serostatus was determined by antibodies for HPV16 early oncoproteins (E6, E7) and regulatory early proteins (E1, E2, E4). The data were split into a training set (70%) for model development and a hold-out testing set (30%) for model performance evaluation, including discriminative ability and calibration. The risk models including demographic, lifestyle risk factors and polygenic risk score showed a reasonable predictive accuracy for head and neck cancer overall. A risk model that also included HPV serology showed substantially improved predictive accuracy for oropharyngeal cancer (AUC = 0.94, 95% CI = 0.92-0.95 in men and AUC = 0.92, 95% CI = 0.88-0.95 in women). The 5-year absolute risk estimates showed distinct trajectories by risk factor profiles. Based on the UK Biobank cohort, the risks of developing oropharyngeal cancer among 60 years old and HPV16 seropositive in the next 5 years ranged from 5.8% to 14.9% with an average of 8.1% for men, 1.3% to 4.4% with an average of 2.2% for women. Absolute risk was generally higher among individuals with heavy smoking, heavy drinking, HPV seropositivity and those with higher polygenic risk score. These risk models may be helpful for identifying people at high risk of developing head and neck cancer.

Yoghurt Intake and Gastric Cancer: A Pooled Analysis of 16 Studies of the StoP Consortium

BACKGROUND

Yoghurt can modify gastrointestinal disease risk, possibly acting on gut microbiota. Our study aimed at exploring the under-investigated association between yoghurt and gastric cancer (GC).

METHODS

We pooled data from 16 studies from the Stomach Cancer Pooling (StoP) Project. Total yoghurt intake was derived from food frequency questionnaires. We calculated study-specific odds ratios (ORs) of GC and the corresponding 95% confidence intervals (CIs) for increasing categories of yoghurt consumption using univariate and multivariable unconditional logistic regression models. A two-stage analysis, with a meta-analysis of the pooled adjusted data, was conducted.

RESULTS

The analysis included 6278 GC cases and 14,181 controls, including 1179 cardia and 3463 non-cardia, 1191 diffuse and 1717 intestinal cases. The overall meta-analysis revealed no association between increasing portions of yoghurt intake (continuous) and GC (OR = 0.98, 95% CI = 0.94-1.02). When restricting to cohort studies, a borderline inverse relationship was found (OR = 0.93, 95% CI = 0.88-0.99). The adjusted and unadjusted OR were 0.92 (95% CI = 0.85-0.99) and 0.78 (95% CI = 0.73-0.84) for any vs. no yoghurt consumption and GC risk. The OR for 1 category of increase in yoghurt intake was 0.96 (95% CI = 0.91-1.02) for cardia, 1.03 (95% CI = 1.00-1.07) for non-cardia, 1.12 (95% CI = 1.07-1.19) for diffuse and 1.02 (95% CI = 0.97-1.06) for intestinal GC. No effect was seen within hospital-based and population-based studies, nor in men or women.

CONCLUSIONS

We found no association between yoghurt and GC in the main adjusted models, despite sensitivity analyses suggesting a protective effect. Additional studies should further address this association.

Mushroom consumption and risk of gastric cancer: a pooled analysis within the stomach cancer pooling project and a combined meta-analysis with other observational studies

Edible mushrooms have high concentrations of vitamins and minerals. They are considered 'functional foods' for their disease-prevention properties. Mushroom consumption may reduce the risk of gastric cancer, the fifth most common cancer worldwide. We investigated the association between mushroom consumption and gastric cancer risk in a pooled analysis within the Stomach Cancer Pooling (StoP) Project and in a meta-analysis that also included previously published studies. A total of 3900 gastric cancer cases and 7792 controls from 11 studies were included in the StoP analysis. Mushroom consumption was measured using food frequency questionnaires. Higher mushroom consumption was associated with a lower risk of gastric cancer [relative risk (RR) for the highest vs. lowest consumption categories, 0.82; 95% confidence interval (CI), 0.71-0.95]. The corresponding RRs were 0.59 (95% CI, 0.26-1.33) in a meta-analysis of four previously published studies and 0.77 for all studies combined (95% CI, 0.63-0.95; n = 15 studies). In geographic subgroup analysis, the pooled risk in Western Pacific countries was (RR, 0.59; 95% CI, 0.40-0.87; n = 6). The stronger effect in Asian countries may reflect high level of antioxidants in mushroom species consumed in Asia.

The Synergetic Effect of Soft Drinks and Sweet/Salty Snacks Consumption and the Moderating Role of Obesity on Preadolescents' Emotions and Behavior: A School-Based Epidemiological Study

The consumption of ultra-processed foods (UPFs) is high along with the prevalence of emotional and behavioral problems among children and adolescents. The present study sought to investigate the synergetic effect of soft drinks and sweet/salty snacks consumption, and the moderating role of obesity on preadolescents' emotions and behavior. A cross-sectional study was conducted among 1728 Greek preadolescents aged 10-12 and their parents, during the school years 2014-2016. Parental and child characteristics were collected anonymously, through self-administered and validated questionnaires. Among others, soft drinks and sweet/salty snacks consumption was recorded, classifying preadolescents as low or at least moderate consumers, while anthropometric characteristics (height, weight, Body Mass Index (BMI)) were also recorded. Approximately 6 out of 10 preadolescents were characterized by at least moderate consumption of either sweet/salty snacks, or soft drinks, while 22.7% of the participants had at least moderate consumption of both soft drinks and sweet/salty snacks. Boys and preadolescents with a lower level of adherence to the Mediterranean diet, as well as those living in a more obesogenic family environment were more likely to be in the higher consumption groups. When compared to just either the moderate consumption of sweet/salty snacks, or the moderate consumption of soft drinks, the combination of both unhealthy eating habits was associated with significantly higher odds of both aggressiveness and loneliness, while the examined relationships were significantly stronger in overweight/obese children. The positive synergistic effect of soft drinks and sweet/salty snacks consumption on preadolescents' emotions of loneliness and aggressive behavior is even burdened by obesity status highlighting the urgent need for policymakers to take preventive measures to halt the detrimental consequences of UPFs consumption on health outcomes, particularly in overweight/obese children. The importance of the improvement of children's unhealthy eating habits by emphasizing the association between food intake and emotional and behavioral status is highlighted.

Nomophobia and Self-Esteem: A Cross Sectional Study in Greek University Students

Nomophobia is a relatively new term describing someone's fear, discomfort, or anxiety when his/her smartphone is not available. It is reported that low self-esteem may contribute to an individual's tendency for nomophobia. The aim of this particular study was to investigate the association between nomophobia and self-esteem among Greek university students. The study sample consisted of 1060 male and female university students aged 18 to 25 years, participating on a voluntary basis with an online anonymous questionnaire. Data were collected through "Nomophobia Questionnaire (NMP-Q)" and "Rosenberg's self-esteem scale (RSES)". All participants exhibited some level of nomophobia, with the moderate level prevailing (59.6%). Regarding self-esteem categories, 18.7% of the participants showed low self-esteem, while the rest showed normal/high levels. Students with low self-esteem were twice as likely to exhibit a higher level of nomophobia compared to those with normal/high (adj Cum OR = 1.99, p value < 0.001). Additionally, women and students having fathers without a university education had a higher risk of exhibiting a greater level of nomophobia (adj Cum OR = 1.56 and 1.44, respectively, p values ≤ 0.008). It was observed that low self-esteem and nomophobia are closely connected. Further investigation into this particular issue is needed to explore potential causality between them.

The Association between Breakfast Macronutrient Composition and Body Weight, in Preadolescence: An Epidemiological Study among Schoolchildren

Over the last few decades, childhood overweight and obesity tend to reach epidemic proportions. The present study aimed to examine whether the composition of breakfast, through the prism of its macronutrient content, could play a part in the development of excess body weight in children. A sample of 1728 Greek students from 47 primary schools was enrolled for the purposes of this study. Their weight and height were measured and their Body Mass Index was calculated and classified according to the International Obesity Task Force criteria. Their dietary habits, breakfast foods of choice, and physical activity were assessed through the use of a self-completed questionnaire. Further assessment of breakfast composition was carried out in order to evaluate its macronutrient content. Initial analysis, which was only energy-adjusted, showed a negative association between body weight and breakfast protein content and a positive association for lipid content. After further adjustment for age, sex, level of adherence to the Mediterranean diet, and physical activity, there was a significant negative association between breakfast protein and excess body weight in children (p = 0.029), as well as a significant positive association of breakfast lipid content (p = 0.028). Breakfast macronutrient content seems to have an effect on body composition in children, independently of overall adherence to the Mediterranean diet and physical activity, however further research is needed in order to elucidate potential pathways.

The Perceptions of Sexual Harassment among Adolescents of Four European Countries

Sexual harassment is a crucial public health issue among adolescents. In order to develop school health promotion programs, there is a need to involve adolescents themselves paying particular attention to their perceptions, beliefs, attitudes and practices. Therefore, the aim of this study was to explore the adolescents' perceptions about sexual harassment as well as the ways it could be prevented. Four focus groups were conducted during an online "camp" in autumn 2021, facilitated by members of SHEHAP project research team. Participants were secondary school students from Finland, Greece, Lithuania and Portugal. The qualitative data was analyzed using content analysis. Concerning how participants perceive sexual harassment, the themes that emerged were: physically expressed sexual harassment; verbally expressed sexual harassment; virtually expressed sexual harassment; violation of self-determination. Virtual environment; school environment; public environment; familiar environment, were identified as the places where sexual harassment may occur. Finally, in regard to the participants' views on the prevention of sexual harassment, the following themes emerged: youth education; adult education aiming teachers and parents; professional, peer and family support; official consequences; health education methods. The findings of the current study can be used for the development of school-based programs aiming to prevent sexual harassment among adolescents.

The Association between Peptic Ulcer Disease and Gastric Cancer: Results from the Stomach Cancer Pooling (StoP) Project Consortium

Simple Summary

Gastric cancer (GC) is the fifth most common type of cancer and the fourth most common cause of cancer-related mortality. In this meta-analysis, we utilized SToP consortium data to investigate the association between gastric ulcer (GU) and duodenal ulcer (DU) and development of GC. Among 4106 GC cases and 6922 controls, we detected a positive association between GU and GC (OR = 3.04, 95% CI: 2.07–4.49). On the other hand, no significant association between DU and GC was detected (OR = 1.03, 95% CI: 0.77–1.39). In the pooled analysis, incorporating 11 case–control studies revealed positive association between the gastric ulcer and risk of gastric cancer.

Abstract

Background. Gastric cancer (GC) is the fifth most common type of cancer and the fourth most common cause of cancer-related mortality. Although the risk of GC and peptic ulcer disease (PUD) is known to be increased by H. pylori infection, evidence regarding the direct relationship between PUD and GC across ethnicities is inconclusive. Therefore, we investigated the association between PUD and GC in the Stomach cancer Pooling (StoP) consortium. Methods. History of peptic ulcer disease was collected using a structured questionnaire in 11 studies in the StoP consortium, including 4106 GC cases and 6922 controls. The two-stage individual-participant data meta-analysis approach was adopted to generate a priori. Unconditional logistic regression and Firth’s penalized maximum likelihood estimator were used to calculate study-specific odds ratios (ORs) and 95% confidence intervals (CIs) for the association between gastric ulcer (GU)/duodenal ulcer (DU) and risk of GC. Results. History of GU and DU was thoroughly reported and used in association analysis, respectively, by 487 cases (12.5%) and 276 controls (4.1%), and 253 cases (7.8%) and 318 controls (6.0%). We found that GU was associated with an increased risk of GC (OR = 3.04, 95% CI: 2.07–4.49). No association between DU and GC risk was observed (OR = 1.03, 95% CI: 0.77–1.39). Conclusions. In the pooled analysis of 11 case–control studies in a large consortium (i.e., the Stomach cancer Pooling (StoP) consortium), we found a positive association between GU and risk of GC and no association between DU and GC risk.

The Association of Sugar-Sweetened Beverages to Children's Weights Status Is Moderated by Frequency of Adding Sugars and Sleep Hours

Adding extra sugars in milk and the moderating effect of sleep has yet to be investigated, setting the aim of this study. A total of 1361 school-aged children were included, aged 10−12 years old, by randomly sampling schools. Data were interview-obtained by trained personnel using a validated 17-item food frequency questionnaire, with specifics on type of milk and extra sugar additions. Analyses were stratified by average recommended hours of sleep. Predictive probability margins were obtained following necessary adjustments. Mean BMI was significantly lower, the level of SSB intake was higher, and the prevalence of adding sugars to milk four or more times per week was higher in children that slept ≥10 h. Most children (64%) consumed full fat milk, 21% had low fat, and 19.7% chocolate milk, with a significantly larger proportion of overweight or obese children consuming full fat or chocolate milk, also adding extra sugars four or more times per week (4.1% compared to 9.6%, and 12.2% compared to 39.5%, respectively). The predictive probability of being overweight or obese exponentially increased for children consuming >0.5 SSB/day while also adding sugars to their milk frequently, although this effect remained significant only for children sleeping <10 h/day. In conclusion, to accurately address the effect of SSBs on children’s body weight, frequency of any type of sugar addition in milk should be accounted for, as well as average sleep hours that may further moderate the effect.

The Association between Stress and Children's Weight Status: A School-Based, Epidemiological Study

Given the evidence on how stress affects weight status in children, this research examined this association among Greek students aged 10−12 years old. Overall, 1452 children and their parents from several urban areas participated in an observational study conducted during the period 2014−2016. Participants completed validated questionnaires. International Obesity Task Force guidelines were used for children’s weight status classification. Descriptive statistics and nested logistic regression models were used. Multivariate correspondence analysis was also used to construct a score to evaluate the children’s stress levels. The overall prevalence of overweight/obesity was 27%. More than 80% of the children appeared to have a medium or high level of stress, mainly due to the school environment. School-related stress increased the odds of obesity in children. The association between stress and overweight/obesity status showed a consistent trend (adjusted odds ratios varied from 1.44 to 1.52, p-values < 0.01). Children’s weight status was associated with several school-related stressors. Although the school environment may play an aggravating role in the weight status of children, family plays a catalyst role in this direction. Therefore, actions have to be promoted in the school community so that children become more health literate on a public health level.

The Role of Milk on Children's Weight Status: An Epidemiological Study among Preadolescents in Greece

Milk consumption contributes greatly to children's diet, playing a pivotal role in the development and structure of bones and the functioning of the musculoskeletal system and the heart. This study investigated the association between the type of milk and childhood overweight/obesity. In the school period 2014-2016, 1728 students aged 10-12 years and their parents participated. The measurement and classification of their weight status were performed through the criteria of the International Obesity Task Force. Among others, the type of milk consumption was recorded. Four categories of the type of milk children consumed were classified (white milk, chocolate milk, both types of milk, and no milk at all). Children consuming only white milk were 33.1% less likely to be overweight/obese in comparison with children who were not consuming milk at all [OR (95% CI): 0.669 (0.516, 0.867), p = 0.002]. The consumption of chocolate milk showed a protective role against childhood overweight/obesity although its association was not consistently significant. This study highlights the significant contribution of milk (and particularly of white milk) consumption to weight management, and thus its promotion should be consistently encouraged. More studies are needed to shed light on the effects of different dairy foods on weight status in childhood.

Allium vegetables intake and the risk of gastric cancer in the Stomach cancer Pooling (StoP) Project

BACKGROUND

The role of allium vegetables on gastric cancer (GC) risk remains unclear.

METHODS

We evaluated whether higher intakes of allium vegetables reduce GC risk using individual participant data from 17 studies participating in the "Stomach cancer Pooling (StoP) Project", including 6097 GC cases and 13,017 controls. Study-specific odds ratios (ORs) were pooled using a two-stage modelling approach.

RESULTS

Total allium vegetables intake was inversely associated with GC risk. The pooled OR for the highest versus the lowest study-specific tertile of consumption was 0.71 (95% confidence interval, CI, 0.56-0.90), with substantial heterogeneity across studies (I² > 50%). Pooled ORs for high versus low consumption were 0.69 (95% CI, 0.55-0.86) for onions and 0.83 (95% CI, 0.75-0.93) for garlic. The inverse association with allium vegetables was evident in Asian (OR 0.50, 95% CI, 0.29-0.86) but not European (OR 0.96, 95% CI, 0.81-1.13) and American (OR 0.66, 95% CI, 0.39-1.11) studies. Results were consistent across all other strata.

CONCLUSIONS

In a worldwide consortium of epidemiological studies, we found an inverse association between allium vegetables and GC, with a stronger association seen in Asian studies. The heterogeneity of results across geographic regions and possible residual confounding suggest caution in results interpretation.

Coffee consumption and gastric cancer: a pooled analysis from the Stomach cancer Pooling Project consortium

OBJECTIVE

This study aimed to evaluate and quantify the relationship between coffee and gastric cancer using a uniquely large dataset from an international consortium of observational studies on gastric cancer, including data from 18 studies, for a total of 8198 cases and 21 419 controls.

METHODS

A two-stage approach was used to obtain the pooled odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for coffee drinkers versus never or rare drinkers. A one-stage logistic mixed-effects model with a random intercept for each study was used to estimate the dose-response relationship. Estimates were adjusted for sex, age and the main recognized risk factors for gastric cancer.

RESULTS

Compared to never or rare coffee drinkers, the estimated pooled OR for coffee drinkers was 1.03 (95% CI, 0.94-1.13). When the amount of coffee intake was considered, the pooled ORs were 0.91 (95% CI, 0.81-1.03) for drinkers of 1-2 cups per day, 0.95 (95% CI, 0.82-1.10) for 3-4 cups, and 0.95 (95% CI, 0.79-1.15) for five or more cups. An OR of 1.20 (95% CI, 0.91-1.58) was found for heavy coffee drinkers (seven or more cups of caffeinated coffee per day). A positive association emerged for high coffee intake (five or more cups per day) for gastric cardia cancer only.

CONCLUSIONS

These findings better quantify the previously available evidence of the absence of a relevant association between coffee consumption and gastric cancer.

[The model of co-production in mental health services]

Service users' right to be involved in decisions concerning their health and quality of life is not only an ethical issue, but also a key aspect for the efficiency and effectiveness of services in modern health systems. Through co-production, service users have an equal partner position in a comprehensive process that includes services design, provision and evaluation. The co-production model is not a new concept but an emerging idea for health services and in particular mental health services. This model is governed by basic principles and values, such as recognizing individuals as active and equal participants with valuable experiences, taking advantage of existing opportunities, sharing and mutual understanding, peer support, tackling discrimination, and facilitation instead of just services provision. Τhe benefits are many and important, both for users (i.e. enhancing trust in services, reducing stigma), and for health professionals and settings (i.e., extroversion and dissemination, increasing needs understanding, changing professionals' attitudes, more efficient use of resources). However, there are limitations which should be considered when co-production is implemented. Regarding co-production, the literature is relatively limited; while there is a plethora of publications on the concepts related to co-production and its principles (e.g., empowerment, advocacy, recovery, etc.). The adoption of the co-production approach in Greece could benefit significantly the mental health services, within the psychiatric reform by establishing an equal relationship between professionals and service users.

eHealth Literacy Among Health Sciences Students in Greece

eÎŮealth literacy is a necessary skill to find and make good use of online health information. However, the general public lacks this skill; it is essential for future health professionals to be able to guide and facilitate the public. The study aimed to examine the perceived eHealth literacy level of health sciences students in Greece. A cross-sectional, online survey was conducted (N=113 students). The questionnaire included socio-demographic data and the eHealth Literacy Scale (eHEALS). Participants' mean eHEALS score was 31.9 with medicine and dentistry students having the highest score (33.7) and other health and caring sciences students the lowest (29.8). There was no statistically significant difference at eHEALS score among participants of different academic year. However, there was a statistically significant difference at eHEALS score among University Departments (p=0.009). Further research in representative samples is required to assess specific needs and improve current educational curricula.

Assessing the association between breastfeeding, type of childbirth and family structure with childhood obesity: results from an observational study among 10-12 years old children

This study examined the association between breastfeeding, type of childbirth, and family structure with childhood obesity. During 2014-2016, 1728 Greek students attending primary schools and their parents were enrolled. Children's weight status was measured and classified according to the International Obesity Task Force criteria. A self-administered questionnaire assessing the type of childbirth, the family structure, and several perinatal and demographic characteristics was used. Factors associated with higher breastfeeding rates were the type of childbirth, high maternal educational level, and nuclear family structure. No association was found between childhood obesity and type of childbirth (p = 0.64) and family structure (p = 0.26). Although the short-term beneficial effects of breastfeeding on childhood obesity are undeniable and it is of great importance to all health professionals to promote breastfeeding, no significant long-term effects on obesity in adolescence were observed. More studies are needed in order to elucidate the role of breastfeeding in obesity status in adolescence.

The Emerging Phenomenon of Nomophobia in Young Adults: A Systematic Review Study

Background

Nomophobia (No MObile PHone PhoBIA) refers to the worry or fear that individuals experience when they are without their mobile phone or they are unable to use it. The term was first coined in 2008 and it is considered a modern type of phobia. The aim of the present study was to retrieve and review the most relevant literature on the prevalence of nomophobia and its relationship with psychosocial and physical health among young adults.

Methods

A systematic literature review was conducted according the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) for original papers on the phenomenon of nomophobia in young adults using the Nomophobia Questionnaire (NMP-Q) as the main measuring instrument. The literature was focused on the 3 main topics of prevalence and level of nomophobia, nomophobia and psychosocial effects, and nomophobia and physical health in young adults.

Findings

The initial literature corpus consisted of 370 articles of which 40 met the inclusion criteria and were analyzed in detail. Nomophobia was observed among 15.2%-99.7% of the participants. Research findings indicated increased psychological, emotional, social, and physical side effects due to excessive smartphone use.

Conclusion

The excessive use of the smartphone is an emerging threat for social, mental, and physical health. There is an increased need for further research in this regard as it is evolving into an epidemic outbreak and concerns directly the field of public health.

Digital health literacy among Greek students during COVID-19 pandemic

Background

Misinformation especially provided through internet is a serious public health threat, and during the COVID-19 pandemic this problem has even amplified, which became known as an information epidemic, a.k.a. infodemic. This is a common problem also in university students who access their information about health via Internet and social media. Digital health literacy (DHL) is an important skill to handle online information and make judgments about their quality and reliability. This study is part of the global COVID-HL survey, aiming at assessing DHL in university and their COVID-19 related health and information needs.

Methods

After receiving ethical approval, data was collected through an online questionnaire among students from one of the largest Universities in Greece. Descriptive statistics as well as bi- and multivariate analyses were conducted using SPSS.

Results

604 university students (mean age 24.3, 73.3% females) completed the survey. 28% indicated that they found it very difficult/ difficult to find the exact information they were looking for, 20.4% to make a choice across all information accessed, and 45.1% stated it is very difficult/ difficult to decide whether the information was reliable or not. According to the descriptive analysis, 25.6% of the students found it very difficult/ difficult to apply the information in their daily life, 23.7% to decide if the information they found is applicable to them and 16.3% to use the information they found to make decisions about their health. Greater satisfaction from information about COVID-19 was significantly associated with greater probability of having sufficient skills in “information search”, “evaluating reliability” and in “determining relevance”.

Conclusions

The results of the study indicate that there is a need to strengthen DHL among university students and develop skills for seeking information on the Internet through health education interventions.

Germline determinants of humoral immune response to HPV-16 protect against oropharyngeal cancer

Although several oropharyngeal cancer (OPC) susceptibility loci have been identified, most previous studies lacked detailed information on human papillomavirus (HPV) status. We conduct a genome-wide analysis by HPV16 serology status in 4,002 oral cancer cases (OPC and oral cavity cancer (OCC)) and 5,256 controls. We detect four susceptibility loci pointing to a distinct genetic predisposition by HPV status. Our most notable finding in the HLA region, that is now confirmed to be specific of HPV(+)OPC risk, reveal two independent loci with strong protective effects, one refining the previously reported HLA class II haplotype association. Antibody levels against HPV16 viral proteins strongly implicate the protective HLA variants as major determinants of humoral response against L1 capsid protein or E6 oncoprotein suggesting a natural immune response against HPV(+)OPC promoted by HLA variants. This indicates that therapeutic vaccines that target E6 and attenuate viral response after established HPV infections might protect against HPV(+)OPC.

Household food spending, parental and childhood's diet quality, in financial crisis: a cross-sectional study in Greece

BACKGROUND

Over the past decade, the financial crisis has affected harshly the household income of Greek people. This study aimed to investigate whether the effect of the financial crisis on food spending has affected the dietary habits in the family environment.

METHODS

Under a cross-sectional study conducted during 2014-2016, 1145 children and their parents completed questionnaires examining socio-economic and dietary characteristics. The MedDietScore and the KIDMED Score were used to assess parental and childhood adherence to the Mediterranean diet, respectively.

RESULTS

The parents who reported that the financial crisis has affected food spending used to consume weekly fewer fruits (3.26 ± 0.94 vs. 3.41 ± 0.90, P = 0.016), carbohydrate foods (3.16 ± 0.57 vs. 2.99 ± 0.55, P < 0.001) and legumes (3.28 ± 0.76 vs. 3.14 ± 0.67, P = 0.001) and more nutrient-poor/energy-dense foods (2.55 ± 0.98 vs. 2.20 ± 0.82, P < 0.001) compared with non-affected parents. Their children showed a decreased weekly consumption of vegetables (2.82 ± 0.90 vs. 2.97 ± 0.98, P = 0.019) and increased weekly consumption of nutrient-poor/energy-dense foods (2.38 ± 0.97 vs. 2.19 ± 0.80, P < 0.001). The affected parents had a lower MedDietScore than non-affected parents (25.76 ± 8.10 vs. 27.03 ± 8.11, P = 0.034). No difference was revealed on the KIDMED Score (P = 0.294).

CONCLUSIONS

The constrained food spending due to financial crisis has an independent and inverse impact on parent's diet quality while keeping unaffected preadolescent's diet quality. This finding highlights the role of parents as a protective 'wall' against the deterioration of their children's diet quality. The modification on the prices of healthy food and the provision of food aid particularly in economically disadvantaged households is underlined.

Sleeping patterns and childhood obesity: an epidemiological study in 1,728 children in Greece

STUDY OBJECTIVES

Sleep is an essential normal function for children's growth and development, but over the years, lifestyle changes have resulted in insufficient sleep, a factor that may be associated with increased childhood obesity. The aim of this study was to evaluate the association between sleep duration and sleep patterns separately on weekdays and weekends regarding children's weight status.

METHODS

This study was conducted among Greek students (55.1% girls) in 2014-2016. Children's weight status was classified according to the International Obesity Task Force tables and guidelines. Sleep duration was determined based on the sleep and wake time that children reported, separately for weekdays and weekends. Classification and regression tree analysis was used to derive sleep patterns and evaluate their relation to children's weight status.

RESULTS

Multiadjusted analysis revealed an inverse association between average duration of sleep on weekdays and weekends with the likelihood of being overweight/obese (odds ratio per 1 hour 0.82; 95% confidence interval, 0.73-0.92). This was more prominent on weekends than on weekdays. Children who had lower duration on weekdays, but catch-up sleep duration on weekends, were 2% (95% confidence interval, 0.97-0.99) less likely to be overweight/obese compared to those children having both less or increased sleep duration on weekdays and weekends.

CONCLUSIONS

Sleep duration and sleep patterns seem to be associated with childhood weight status. Interventions should be developed to educate parents on the importance of an adequate sleep duration and healthy sleep patterns for their children's healthy development.

Health knowledge and motives on tattooing: A community-based cross-sectional study in Greece

BACKGROUND

Tattooing is becoming an increasingly common trend mainly but not merely among the youth. However, the choice of ink body art is associated with an increase of dermatological complications.

AIM

To assess young persons' health knowledge and motives toward tattooing.

METHODS

The main instrument used was an online structured questionnaire with scaling and dichotomous questions, consisting of three components: (a) the participants' sociodemographic profile, (b) health knowledge assessment, (c) motives toward or against tattooing. Simple univariate techniques and multiple logistic regression were used to data analysis. Two logistic models were developed having as dependent variable whether the respondents have or would like to have a tattoo. The independent variables in the models were sociodemographic characteristics of participants and three variables concerning respondents' health knowledge and motives on tattooing.

RESULTS

The study sample amounted to 629 young adults living in Athens, the capital city of Greece. The prevailing age group among tattooed persons was 19-25 years old (69.5%), with females being more likely to be tattooed than males. Among tattooed participants, knowledge in specific health complications appeared high, while in other potential complications was particularly low. The main motives identified were ideology/message and aesthetics/fashion (77% in total). Quite interesting, participants with medium and high health knowledge level showed, respectively 50%, and three times higher probability of having tattoos compared to low level. Only 16.2% of the tattooed participants regarded tattoo as dangerous to health (p < 0.0005).

CONCLUSIONS

The likelihood of acquiring ink body art is increasing critically among young adults. Even though this tendency is accompanied with adequate levels of knowledge concerning health hazards, systematic health education programs for more informed and safe choices are needed to be implemented, with particular emphasis on young people.

Parental health status in relation to the nutrition literacy level of their children: Results from an epidemiological study in 1728 Greek students

BACKGROUND: Children’s dietary behaviors seem tract into adulthood and as a result preventing strategies to establish healthy behaviors from early stages of life are needed. Nutrition knowledge is essential for behavioral change. OBJECTIVE: To examine whether the status of parental health related to their children’s nutrition literacy level through their perceptions mainly of healthy eating attitudes METHODS: A cross-sectional survey was conducted in Greece among 1,728 schoolchildren aged 10–12 years old. The sample was collected in the school setting during the school years of 2014–2016. Children completed anonymously a self-administered questionnaire about their knowledge and perceptions of a healthy diet while their parents completed another suitable questionnaire about family health status. RESULTS: Paternal BMI status and hypertension were inversely associated with the level of nutrition literacy of their children by b = –0.043 (95%CI: (–0.082, –0.003; p = 0.036) and by b = –0.600 (95%CI: –1.181, –0.019; p = 0.043), respectively. Parental health status, specifically, paternal diabetes and maternal dyslipidemia were associated with children’s higher level of nutrition literacy by b = 0.729 (95%CI: 0.002, 1.456; p = 0.049) and by b = 0.730 (95%CI: 0.086, 1.374; p = 0.026), respectively. CONCLUSIONS: Parental health status partially affects, either negatively or positively, the level of nutrition literacy of their children. This impact depends on whether parents follow nutritional recommendations to improve their health.

Parental consumption of ultra-processed, high-fat products has no association with childhood overweight/obesity: an epidemiological study among 10-12-years-old children in Greece

BACKGROUND

Overweight and obesity during childhood consist two of the most important public health issues in the 21st century. Consumption of high-fat processed food has been increased alarmingly.

OBJECTIVE

To examine the association between parental ultra-processed, high-fat products' consumption and childhood overweight/obesity.

METHODS

A cross-sectional survey, conducted among 422 children, aged 10-12 years, and their parents, during school years 2014-16. Parental and child data were collected through self-administered, anonymous and validated questionnaires. Among others, high-fat ultra-processed food consumption was also recorded. Children's weight status was based on gender- and age-specific tables derived from the International Obesity Task Force body mass index (BMI) cut-offs.

RESULTS

The prevalence of obesity in the reference population was 2.9%, whereas the prevalence of overweight was 19.3%. A strong correlation was observed between children's and their parents' BMI status (P < 0.001). Multi-adjusted data analysis revealed no association between parental intake of ultra-processed, high-fat products and children overweight/obesity. Similarly, when the data analysis accounted for family income and physical activity status of the children, the aforementioned results remained insignificant.

CONCLUSION

Despite the fact that parents' specific dietary habits seem not to affect their children's weight status, public health programs should consider parental nutrition education and mobilization as a preventive measure for childhood overweight/obesity.

Inverse Association Between Health Literacy and Obesity Among Children in Greece: A School-Based, Cross-Sectional Epidemiological Study

Children's health literacy is a crucial pillar of health. This study is aimed to examine the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. A population-based, cross-sectional observational study enrolling 1,728 students (795 boys), aged 10 to 12 years old, was conducted during school years 2014-2016. A health literacy index (range 0-100) was created through an item response theory hybrid model, by combining a variety of beliefs and perceptions of children about health. The mean health literacy score was 70.4 (±18.7). The majority of children (63.8%) had a "high" level (i.e., >67/100) of health literacy, 30.5% had a "medium" level (i.e., 34-66/100) of health literacy, while a small proportion of children (5.7%) had a "low" level (i.e., <33/100). Girls exhibited a higher level of health literacy than boys (71.7 ± 18.3 vs. 68.8 ± 19.1, p < .01). Regarding body weight status, 21.7% of children was overweight and 5.0% was obese. Linear regression models showed that the health literacy score was inversely associated with children's body mass index (regression coefficient [95% CI]: -0.010 [-0.018, -0.001]), after adjusting for dietary habits, physical activity levels, and other potential confounders. Health literacy seems to be a dominant characteristic of children's weight status; therefore, school planning, as well as public health policy actions should emphasize on the ability of children's capacity to obtain, process, and understand basic health information.

Fermentative Foods: Microbiology, Biochemistry, Potential Human Health Benefits and Public Health Issues

Fermented foods identify cultures and civilizations. History, climate and the particulars of local production of raw materials have urged humanity to exploit various pathways of fermentation to produce a wide variety of traditional edible products which represent adaptations to specific conditions. Nowadays, industrial-scale production has flooded the markets with ferments. According to recent estimates, the current size of the global market of fermented foods is in the vicinity of USD 30 billion, with increasing trends. Modern challenges include tailor-made fermented foods for people with special dietary needs, such as patients suffering from Crohn's disease or other ailments. Another major challenge concerns the safety of artisan fermented products, an issue that could be tackled with the aid of molecular biology and concerns not only the presence of pathogens but also the foodborne microbial resistance. The basis of all these is, of course, the microbiome, an aggregation of different species of bacteria and yeasts that thrives on the carbohydrates of the raw materials. In this review, the microbiology of fermented foods is discussed with a special reference to groups of products and to specific products indicative of the diversity that a fermentation process can take. Their impact is also discussed with emphasis on health and oral health status. From Hippocrates until modern approaches to disease therapy, diet was thought to be of the most important factors for health stability of the human natural microbiome. After all, to quote Pasteur, "Gentlemen, the microbes will have the last word for human health." In that sense, it is the microbiomes of fermented foods that will acquire a leading role in future nutrition and therapeutics.

The Influence of Adherence to the Mediterranean Diet among Children and Their Parents in Relation to Childhood Overweight/Obesity: A Cross-Sectional Study in Greece

Background: Childhood overweight/obesity constitutes a serious issue, as may cause several health problems. The main characteristics of the Mediterranean Diet have been acknowledged as the most appropriate shield mainly for obesity. Methods: The study was performed on 1728 primary students, during school years 2014-2016, in Greece. Children and their parents completed questionnaires which included dietary and lifestyle habits. The KIDMED score (range -4 to 12) was used to assess the level of childhood adherence to the Mediterranean diet and the MedDietScore (range 0 to 55) was used to assess parental adherence. For the purposes of this analysis, the examined sample was n = 875 of students (522 girls)-parents pairs whose level of adherence to the Mediterranean diet was able to be evaluated. Results: The prevalence of overweight and obesity in the Greek sample was 26.0%, according to International Obesity Task Force (IOTF) cutoff criteria for children. KIDMED Score was significantly lower in children with overweight/obesity compared with children with normal weight (4.65 ± 2.14 vs. 5.16 ± 2.05, p = 0.002). The multiadjusted analysis revealed that children close to the Mediterranean diet were less likely to be overweight/obese (p < 0.001), either parents are away from or close to the Mediterranean diet. Conclusions: This study revealed that children's adherence to the Mediterranean diet was inversely associated with weight status either parents are away from or close to this dietary pattern. Future interventions against childhood obesity have to take into consideration the crucial importance of familial aggregation of healthy food choices and interfamily influences in the home environment on children's weight status.

Fruits and vegetables intake and gastric cancer risk: A pooled analysis within the Stomach cancer Pooling Project

A low intake of fruits and vegetables is a risk factor for gastric cancer, although there is uncertainty regarding the magnitude of the associations. In our study, the relationship between fruits and vegetables intake and gastric cancer was assessed, complementing a previous work on the association betweenconsumption of citrus fruits and gastric cancer. Data from 25 studies (8456 cases and 21 133 controls) with information on fruits and/or vegetables intake were used. A two-stage approach based on random-effects models was used to pool study-specific adjusted (sex, age and the main known risk factors for gastric cancer) odds ratios (ORs) and the corresponding 95% confidence intervals (CIs). Exposure-response relations, including linear and nonlinear associations, were modeled using one- and two-order fractional polynomials. Gastric cancer risk was lower for a higher intake of fruits (OR: 0.76, 95% CI: 0.64-0.90), noncitrus fruits (OR: 0.86, 95% CI: 0.73-1.02), vegetables (OR: 0.68, 95% CI: 0.56-0.84), and fruits and vegetables (OR: 0.61, 95% CI: 0.49-0.75); results were consistent across sociodemographic and lifestyles categories, as well as study characteristics. Exposure-response analyses showed an increasingly protective effect of portions/day of fruits (OR: 0.64, 95% CI: 0.57-0.73 for six portions), noncitrus fruits (OR: 0.71, 95% CI: 0.61-0.83 for six portions) and vegetables (OR: 0.51, 95% CI: 0.43-0.60 for 10 portions). A protective effect of all fruits, noncitrus fruits and vegetables was confirmed, supporting further dietary recommendations to decrease the burden of gastric cancer.

Nationwide Survey in Greece about Knowledge, Risk Perceptions, and Preventive Behaviors for COVID-19 during the General Lockdown in April 2020

Background: The aim of this study was to investigate the knowledge, attitudes, and practices of the Greek general population toward coronavirus disease 2019 (COVID-19) during the lockdown period in April 2020, to examine factors associated with misperceptions and to determine behavioral patterns that may require interventions. Methods: A cross-sectional study of the general Greek population (N = 1858) was conducted. A geographically stratified cluster sampling was implemented. A questionnaire was composed consisting of 35 questions. Data collection took place from 15 April to 2 May 2020. A random-digit dialing survey was conducted by 29 interviewers. Results: The majority of respondents (62.7%) answered ≥12/17 questions correctly. Participants aged 18–44 years, male gender, specific occupations (freelancer, unemployed, housewife, retiree) and those who sought information about COVID-19 from less than two sources received lower aggregated scores on knowledge questions. Regarding attitudes toward future vaccination, 18.9% declared that were against it, while 81.1% that they may consider or will be vaccinated. About 40% were not using a face mask and only 42% washed their hands appropriately. Conclusion: Adjusting information campaigns targeting especially people below 45 years of age can help to sensitize them and realise their role to control the spread. Further targeted surveys are needed to adjust/design prevention campaigns.

The association between adherence to the Mediterranean diet and childhood obesity; the role of family structure: Results from an epidemiological study in 1728 Greek students

BACKGROUND

Childhood obesity is among the leading public health challenges, worldwide.

AIM

To examine the association between children's adherence to the Mediterranean diet (MD) and weight status taking into account family structure and related behaviors.

METHODS

1728 primary-school Greek students (46% males), from Athens metropolitan area, island of Crete, and the Peloponnese region, were enroled during school years 2014-2016. Children and their parents completed questionnaires which, among others, recorded family structure (i.e., married/cohabited, divorced, single parent, and widowed), dietary and lifestyle habits. Adherence to the MD was assessed through the KIDMED score (range - 4 to 12). Children's body mass index was calculated and classified as normal, overweight/obese, according to the International Obesity Task Force classification. The working sample was 1142 children (44% males) with a recorded family structure.

RESULTS

The prevalence of overweight was 21.7% and obesity was 5.0%; overweight/obesity prevalence was higher among males than females (32.4% vs. 23.3%; p < 0.001). Overweight/obese children had a lower KIDMED score compared to normal weight (median (range): 4 (-2, 11) vs. 5 (-1, 10), p = 0.05). An inverse association between KIDMED score and children's weight status (odds ratio (OR) (95% confidence interval (CI)): 0.95 (0.89-0.99)) was observed. Interaction between family structure and KIDMED was observed (p < 0.001); stratified analysis revealed that in children from nuclear families the KIDMED score was inversely associated with the likelihood of overweight/obesity (OR (95% CI): 0.95 (0.88-1.00)), whereas in children from single-parent families it was not (OR (95% CI): 0.94 (0.79-1.12)).

CONCLUSION

Adherence to the MD plays a protective role against childhood overweight/obesity, particularly among children living in nuclear families.

Lack of association between dietary fibres intake and childhood obesity: an epidemiological study among preadolescents in Greece

The aim of this study was to evaluate whether dietary fibres intake is associated with childhood obesity. From 2014 to 2016, a sample of 1728 Greek boys and girls students, 10-12 years and their parents were enrolled in the study. Dietary fibres intake was assessed through food questionnaires and child's body mass status was defined according to the International Obesity Task Force (IOTF)'s criteria. Prevalence of combined overweight/obesity was 26.7%, with boys having significantly higher prevalence than girls (31.5 versus 24.7%, p < 0.001). Logistic regression analysis, after various adjustments were made, revealed no association between dietary fibres intake and obesity/overweight (Odds Ratio = 0.76; 95% CI 0.48, 1.19). The lack of an association between dietary fibres intake and overweight/obesity status among pre-adolescents could be attributed to various reasons such as, methodological issues reflecting the study's design, the measurement of exposure or due to true absence of a relationship. Nevertheless, fibres consumption should not be prevented, but, promoted under the context of a balanced diet, because of their numerous pleiotropic health effects.

Breakfast consumption and obesity among preadolescents: An epidemiological study

BACKGROUND

This study aimed to examine the association between breakfast consumption and childhood weight status, in relation to various socioeconomic and lifestyle factors.

METHODS

A cross-sectional survey was conducted including 1,728 children aged 10-12 years and their parents, during the school years 2014-2016. Primary schools from five Greek counties (including the Athens metropolitan area) were randomly selected. Parental and child data were collected through self-administered, anonymous questionnaires. Children's weight status was based on gender- and age-specific tables derived from the International Obesity Task Force body mass index cutoffs. Logistic regression was used to determine the association between frequency and type of breakfast consumption and children's weight status.

RESULTS

The frequency of breakfast consumption was not associated with childhood overweight or obesity, even when other factors were included in the analysis like sex, age, physical activity, meals / day, family annual income, parental weight status, parental physical activity level, parental educational level and parental employment status. From the nine foods that were included only the consumption of bread or rusks and chocolate milk were found to have a negative association with childhood overweight or obesity (odds ratio: 0.51; 95% CI: 0.34, 0.79 and OR: 0.50; 95% CI: 0.28, 0.87, respectively).

CONCLUSIONS

The result that frequency of breakfast consumption was not associated with children's overweight / obesity may lead to a deeper investigation of the foods consumed during breakfast. Bread or rusks and chocolate milk seemed to have a protective effect; further nutritional analysis is needed to explore the potential mechanisms of this observation.

Meat intake and risk of gastric cancer in the Stomach cancer Pooling (StoP) project

The consumption of processed meat has been associated with noncardia gastric cancer, but evidence regarding a possible role of red meat is more limited. Our study aims to quantify the association between meat consumption, namely white, red and processed meat, and the risk of gastric cancer, through individual participant data meta-analysis of studies participating in the "Stomach cancer Pooling (StoP) Project". Data from 22 studies, including 11,443 cases and 28,029 controls, were used. Study-specific odds ratios (ORs) were pooled through a two-stage approach based on random-effects models. An exposure-response relationship was modeled, using one and two-order fractional polynomials, to evaluate the possible nonlinear association between meat intake and gastric cancer. An increased risk of gastric cancer was observed for the consumption of all types of meat (highest vs. lowest tertile), which was statistically significant for red (OR: 1.24; 95% CI: 1.00-1.53), processed (OR: 1.23; 95% CI: 1.06-1.43) and total meat (OR: 1.30; 95% CI: 1.09-1.55). Exposure-response analyses showed an increasing risk of gastric cancer with increasing consumption of both processed and red meat, with the highest OR being observed for an intake of 150 g/day of red meat (OR: 1.85; 95% CI: 1.56-2.20). This work provides robust evidence on the relation between the consumption of different types of meat and gastric cancer. Adherence to dietary recommendations to reduce meat consumption may contribute to a reduction in the burden of gastric cancer.

Patterns of e-cigarette use, biochemically verified smoking status and self-reported changes in health status of a random sample of vapeshops customers in Greece

To understand the population impact of e-cigarettes, it is important to examine the profile of e-cigarette users. The purpose was to examine the characteristics, patterns of e-cigarette use and smoking status of a random sample of vapeshops customers in Greece. Fourteen vapeshops were randomly selected in the region of Athens. Every third customer buying products for personal use was recruited by a researcher visiting the vapeshops. Current smoking status was assessed by measuring exhaled carbon monoxide (eCO), with a value ≥ 7 ppm being used to classify subjects as current smokers. A questionnaire was used to examine past smoking status, patterns of e-cigarette use, changes in health status and experienced side effects. Logistic regression analysis was performed to identify correlates of being a former smoker. A total of 309 participants were analyzed, with 82.5% being daily e-cigarette users. The vast majority (98%) were smokers before e-cigarette use initiation, with 69.6% of them having eCO < 7 ppm (former smokers). Only 1% were never smokers, and 1% had quit smoking before e-cigarette use initiation; all of them had eCO < 7 ppm. Most participants were using third-generation devices (61.8%) and were using non-tobacco flavors (58.9%). The average liquid consumption was 5 mL/day. Most participants experienced health benefits, mainly improvement in physical status, exercise capacity, olfactory and gustatory senses, while the most common side effects were throat irritation and cough. The strongest correlate of being a former smoker was daily e-cigarette use. Vapeshops customers in Greece are mainly current and former smokers with the majority of them having quit smoking. E-cigarette use by never smokers is rare and none of them subsequently initiate smoking.

Parental weight status and early adolescence body weight in association with socioeconomic factors

BACKGROUND

Childhood obesity remains a major health issue. The understanding of the multifactorial nature of childhood obesity remains the cornerstone to eliminate the rising trends. This study aimed to examine the association between parental and childhood weight status, in relation to various socioeconomic (SE) factors.

METHODS

A cross-sectional survey was conducted including 1190 children aged 10-12 years and their parents, during school years 2014-2016. Primary schools from five Greek counties (including Athens metropolitan area) were randomly selected. Parental and child data were collected through self-administered, anonymous questionnaires. Children's weight status was based on gender- and age-specific tables derived from the International Obesity Task Force body mass index (BMI) cut offs. General Linear Model (GLM), Univariate and multivariate analyses were applied. Multiple logistic regressions was used to determine the association between children and parents' weight status.

RESULTS

Childhood prevalence of overweight and obesity was 25.9% (21.8% overweight and 4.1% obese), with prevalence being significantly higher in males (31.7% compared to 21.3%; P for gender differences < 0.001). The percent of overweight and obese male (34.4% and 43.1%) and female children (20.3% and 31.8%) significantly increased with paternal overweight and obesity status, respectively. The same relationship was observed between male children and maternal overweight and obesity status (43.4% and 65.7%). This was not evident among females (27% and 23.2%). Regression analysis showed a significant positive association with parental BMI, a negative association with both parental educational levels (low to high), living space, and parental age (P < 0.05, for all). Children's likelihood of being overweight or obese increased significantly with increasing parental weight status (P < 0.001).

CONCLUSIONS

Parental weight status remained the most significant predictive factor for early adolescence obesity among various SE factors. Health promotion strategies should consider parental education as an effective childhood obesity preventive measure.
