Overweight/obesity and factors associated with body mass index during adolescence: the VYRONAS study.

AIM: To describe overweight and obese adolescents and to determine any correlations between an adolescent's body mass index (BMI) with personal (age, gender), lifestyle (sedentary/sport activities, smoking status) and parental (smoking status, BMI, number of cars) characteristics. METHODS: Cross-sectional data on weight, height and various characteristics from 2008 Greek adolescents (12- to 17-year olds, 50.85% boys), measured in 2005-2007, were used. RESULTS: Almost 1 in 5 (19.2%) boys and 1 in 7 (13.2%) girls 12-17 years of age were overweight while 4.4% of the boys and 1.7% of the girls were obese. The adolescents' age, mother's smoking status, father's and mother's BMI predicted boys' and girls' BMI (b = 0.551, 0.203, 0.110, 0.495 for boys, b = 0.233, 0.187, 0.180, 0.531 for girls, respectively, p < or = 0.05). Univariate analysis revealed that television watching/using personal computer/playing video games and playtime were not correlated with BMI, while an inverse association of exercising for > or = 5 h/week and BMI was found in both boys and girls (b =-1.098, -0.528, p = 0.005, 0.004 respectively). CONCLUSION: The results of our study underline the high prevalence of obesity during adolescence in Greece. Age and parental unhealthy behaviour (increased BMI and maternal smoking status) were positive predictors of increased BMI of adolescents in both genders.

Dietary patterns in relation to socio-economic and lifestyle characteristics among Greek adolescents: a multivariate analysis.

BACKGROUND: We sought to evaluate the relationship between selected lifestyle and socio-economic characteristics and dietary habits of Greek adolescents. METHODS: During 2004, 2118 school adolescents were selected from twelve schools in Vyronas region, Athens. Dietary intake was assessed through a semi-quantitative FFQ. Principal components analysis was applied to extract dietary patterns. RESULTS: Seven components, explaining the 50% of the total variation in intake, were extracted. Component 1 ('junk food' pattern) was heavily loaded by the consumption of 'sweet' and 'salty' snacks, soft drinks and other 'fast foods'. Component 2 was characterized as 'red meat' consumption pattern. Component 3 was characterized by the consumption of vegetables, fruits and juices. Component 4 was characterized by the intake of dairy products, pasta and wholegrain bread. Component 5 can be described as rice, fish, potatoes and poultry intake. Component 6 was characterized by the consumption of 'traditional Greek cooked foods' and legumes, and component 7 was characterized by the consumption of eggs and white bread. Time spent watching television was positively associated with the 'junk food' pattern and inversely associated with the 'vegetarian/healthy' pattern. Moreover, the 'junk food' pattern was positively related to smoking status and the 'vegetarian/healthy' pattern was positively correlated with sports activities outside school. CONCLUSION: An unhealthy dietary behaviour is associated with an overall unhealthy lifestyle. Taking into account the fact that unhealthy eating habits and sedentary lifestyle have been associated with increased obesity prevalence, school- or community-based programmes should be conducted promoting healthy dietary and lifestyle behaviours.

Evaluation of a clinical attachment in Primary Health Care as a component of undergraduate medical education.

INTRODUCTION: It seems that there is a trend in undergraduate medical education towards including clinical attachments in primary health care (PHC) worldwide. The benefits of such initiatives are already well described. The aim of this study was to evaluate the effect of a clinical attachment in undergraduate medical students in a European country with an odd medical educational system that essentially lacks any kind of academic PHC departments. METHODS: The study was undertaken during 2005-2007. A non-mandatory 1-week clinical attachment in PHC/general practice was organized in an urban PHC unit by general practitioners with educational experience in collaboration with the Department of Physiology of the local medical school. The participants were a prospective cohort of medical students in the 2nd year of undergraduate studies. All participating students sat a pre-defined clinical exam which consisted of multiple choice questions, mini case papers and an objective-structured clinical examination before and after the attachment. In addition, the students rated the whole process. RESULTS: The response ratio was 77.06%. The mean score on objective structured clinical examination of participants increased from 30.70/100 to 62.28/100 (p < 0.001). The students' impression of the study was rather positive (4.39/5). DISCUSSION: The educational intervention of including a clinical attachment in an undergraduate curriculum seems to have encouraging results, considering the peculiarity of inexistence of academic departments of PHC or General Practice in the national medical schools and the inexperience of students regarding similar concepts.

Extensive atypical genital herpes simplex type 2 infection as an initial manifestation of acquired immune deficiency syndrome.

We present a case of an ulcerative lesion of the genitalia starting one year before in a 33-year-old man. Histopathologic examination revealed herpes virus infection, which suggested the existence of cell-mediated immunodeficiency. Human immunodeficiency virus (HIV) infection was confirmed by ELISA and Western blot test. The patient was treated with intravenous acyclovir, which led to complete remission. We underline the importance of early detecting and diagnosing patients with similar clinical manifestation as a sign of significant underlying immunodeficiency.

Dissatisfaction with cardiovascular health and primary health care services: Southern Mani, isolated area in Europe. A case study.

INTRODUCTION: Access to local providers of primary health care (PHC) services and their utilisation is a challenge faced by the authorities of developed as well as developing countries. The aim of our study was to assess and evaluate the level of satisfaction with the currently provided cardiovascular and PHC services in the southernmost region of continental Greece (and of the European Union), Southern Mani. METHODS: The sample (422 individuals, 375 of whom finally participated: 187 men and 188 women, response ratio: 88.86%), was selected between January-December 2006, using stratified randomisation by sex and age. Participants were asked to fill in a validated questionnaire containing socio-demographic data and items about the health needs/level of satisfaction with cardiovascular health and PHC services, as well as two indices for cardiovascular health: i) frequency of international normalised ratio (INR) measurement in case of atrial fibrillation, and ii) history of timely thrombolysis in case of acute myocardial infarction. RESULTS: The majority of the responders stated that their level of satisfaction with PHC services was "low" or "very low" (total: 52.80%), while the percentage of dissatisfaction with cardiovascular health services was 56.0%. In addition, most of the participants expressed a strong wish for improvement of PHC services (71.33%). The level of satisfaction with PHC services was higher than with cardiovascular health services (2.49 +/- 1.26 vs. 2.38 +/- 1.24; p < 0.001). Satisfaction scores for both cardiovascular health and PHC services were negatively associated with the distance from the nearest PHC Unit. Only 11.1% of patients (95% CI: 0.3%-48.2%) reported annual testing of prothrombin time more than once, while among those with a history of acute myocardial infarction, none reported timely thrombolysis (0%, one-sided 97.5% CI: 0%-41.0%). CONCLUSION: It is evident that a large portion of the Southern Mani population perceives the provided cardiovascular health and PHC services as problematic, while the distance from the nearest PHC unit seems to be one of the most important factors and predictors of dissatisfaction. The provision of efficient PHC services in isolated areas is a matter that should be re-evaluated.

An assisted-living home architecture with integrated healthcare services for elderly people.

Since the population of elderly people grows absolutely and in relation to the overall population in the world, the improvement of the quality of life of elderly people at home is of a great importance. This can be achieved through the development of generic technologies for managing their domestic ambient environment consisting of medical sensors, entertainment equipment, home automation systems and white goods, increasing their autonomy and safety. In this context, the provision intelligent interactive healthcare services will improve their daily life and allowing at the same time the continuous monitoring of their health and their effective treatment.

Comparison of primary health care services between urban and rural settings after the introduction of the first urban health centre in Vyronas, Greece.

BACKGROUND: Discrepancies in primary health care (PHC) services between urban and rural settings have already been studied in many countries; however, limited information exists regarding countries, such as Greece, where public Health Centres dedicated to primary care have not been in existence in major cities. The objective of this study was to evaluate points of divergence or convergence between an urban and a rural health centre, in an attempt to underline challenges faced by the introduction of urban health centres in Greece. METHODS: A cross-sectional analysis was conducted in the Health Centre of Vyronas, Athens, Greece and in the Health Centre of Nea (New) Madytos, Thessaloniki Prefecture, Greece between February 2004 and February 2006. The profile of the population seeking care, as well as data on the services provided were collected and compared. In addition, the reason for choosing each primary health care unit was also recorded. RESULTS: More patients visited the urban centre (145415 vs. 112513), while the pattern of services utilized by the citizens differed significantly (p < 0.001) between the two Health Centres. The frequency of diagnoses made according to ICPC-2 was not similar in the two Health Centres (p < 0.001). The three most frequent reasons for the adults choosing the Health Centre for their problem were low waiting time, proximity to residence and satisfaction with the services provided in previous visits in Vyronas. CONCLUSION: The results of this study highlight the significant differences regarding PHC services utilization between an urban and a rural population. Urban citizens seem to have different health needs and reasons for choosing a PHC unit than residents of the Greek countryside. Proximity to health services and the public character of the urban health centre seem to be its main advantages.

Does educational printed material manage to change compliance with prostate cancer screening?

BACKGROUND/AIM: The effects of printed educational material on cancer screening in women (Pap test and mammography) are well documented and confirmed by several studies. The aim of our study was to evaluate the impact of similar printed educational material on prostate cancer screening by PSA and DRE. MATERIAL AND METHODS: Thousand five hundred men aged between 50 and 86 years of age, who attended our institutions for various medical conditions except prostate-related conditions, were randomly assigned to two study groups. Men in the informed group, received an educational leaflet with simple, general information on prostate cancer screening methods given by their physician along with treatment and other regular recommendations, while men in the non-informed group, were only informed by their physician in the examination room during an interview. RESULTS: After 24 months, there was no statistically significant difference between the two groups in terms of DRE screening. The percentages of men who were actually screened by DRE were 4 and 5% in the informed and non-informed groups, respectively, while the difference in the percentages of PSA screening was of statistical significance, with 31% of men screened in the non-informed group as compared to 93% of men screened in the informational leaflet group. CONCLUSIONS: A single, one-shift distribution of printed educational material on prostate cancer screening, changed their attitude regarding prostate cancer screening only in favour of PSA testing, while did not manage to change the DRE acceptance behavior. However, since the combination of the two tests is more sensitive for diagnosis than either one alone, there is a need of introducing intervention strategies, in the efforts of ameliorating the prostate cancer screening behavior.

Parental Body Mass Index in association with the prevalence of overweight/obesity among adolescents in Greece; dietary and lifestyle habits in the context of the family environment: the Vyronas study.

The objective of this study was to evaluate whether Parental Body Mass Index is associated with overweight/obesity in a sample of Greek adolescents, taking into consideration dietary and lifestyle habits. The Vyronas study is a cross-sectional health and nutrition survey. During 2004/2005, 2008 schoolchildren were selected. BMI was calculated for both parents and adolescents. A semi-quantitative Food Frequency Questionnaire was applied. Results demonstrated that there is a strong positive association between the parental overweight/obesity status and their offspring's BMI. Some dietary and lifestyle habits seem to affect boys and girls BMI in relation to parental status differently.

Acute and chronic paronychia.

Paronychia is an inflammation of the folds of tissue surrounding the nail of a toe or finger. Paronychia may be classified as either acute or chronic. The main factor associated with the development of acute paronychia is direct or indirect trauma to the cuticle or nail fold. This enables pathogens to inoculate the nail, resulting in infection. Treatment options for acute paronychia include warm compresses; topical antibiotics, with or without corticosteroids; oral antibiotics; or surgical incision and drainage for more severe cases. Chronic paronychia is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. The patient should avoid exposure to contact irritants; treatment of underlying inflammation and infection is recommended, using a combination of a broad-spectrum topical antifungal agent and a corticosteroid. Application of emollient lotions may be beneficial. Topical steroid creams are more effective than systemic antifungals in the treatment of chronic paronychia. In recalcitrant chronic paronychia, en bloc excision of the proximal nail fold is an option. Alternatively, an eponychial marsupialization, with or without nail removal, may be performed.

The association between consumption of breakfast cereals and BMI in schoolchildren aged 12-17 years: the VYRONAS study.

OBJECTIVE: To evaluate whether consumption of breakfast cereals is associated with BMI in a sample of Greek adolescents. DESIGN: A cross-sectional health and nutrition survey. SETTING AND SUBJECTS: During 2004-5, 2008 schoolchildren aged 12-17 years were selected from twelve schools located in Vyronas region (Athens metropolitan area). Height and weight were measured and BMI was calculated. A semiquantitative FFQ was applied and multiple logistic regression analysis was used. RESULTS: Overall, 4.7% of boys and 1.7% of girls were obese, whereas 19.4% of boys and 13.2% of girls were overweight. Only 20.7% of boys and 15.5% of girls reported that they consume cereals as a first choice for breakfast. Consumption of breakfast cereals was associated with lower BMI in boys (P=0.08) and girls(P=0.019), irrespective of age and physical activity status. More prominent results were observed for daily cereal consumption or for more than two daily servings of cereals consumed for breakfast. Consumption of pre-sweetened breakfast cereals was associated with lower BMI compared with non-pre-sweetened or no intake of cereals, in both genders (P<0.001). Consumption of breakfast cereals was associated with 33% (95% CI 14%, 48%) lower likelihood of overweight/obesity, irrespective of age, sex and physical activity status. CONCLUSIONS: Consumption of breakfast cereals was associated with lower BMI levels and a lower likelihood of overweight/obesity in both genders; thus a solid basis for public health professionals could be built when issuing advice on weight management.

Dietary habits, physical activity and prevalence of overweight/obesity among adolescents in Greece: the Vyronas study.

BACKGROUND: The aim was to evaluate the dietary habits and some lifestyle characteristics of Greek adolescents 12-17 years of age in relation to the prevalence of overweight/obesity. MATERIAL/METHODS: During 2004-2005, 2008 school-aged adolescents (1021 male and 987 female) were selected from all public schools located in the Vyronas region of Athens. The participation rate was 95%. Height and weight were measured and the body mass index (BMI) was calculated. Cut-off points for BMI defining obesity and overweight for gender and age were calculated in accordance with international standards. A semi-quantitative Food Frequency Questionnaire was applied and multiple logistic regression was used to investigate the association between dietary habits/lifestyle characteristics and overweight/obesity in adolescents. RESULTS: Eating cereals for breakfast and the number of meals per day (including snacks) were inversely associated with BMI in males. Furthermore, eating poultry as a meal and sedentary activities were positively associated with BMI in females, while eating breakfast more than five times per week and eating cereals for breakfast were inversely associated with BMI in females. Overall, 4.4% of males and 1.7% of females were obese and 19.2% of males and 13.2% of females were overweight. CONCLUSIONS: The consumption of cereals for breakfast and the daily frequency of meals consumed were associated with overweight/obesity in males, whereas the frequency of eating breakfast, the consumption of cereals for breakfast, the consumption of poultry, and the hours spent for activities excluding sports were associated with overweight/obesity in females.

General Practice as a career choice among undergraduate medical students in Greece.

BACKGROUND: Although General Practice (GP) was recognized as a medical specialty in Greece in 1986, the number of GPs is insufficient to cover needs and only few medical graduates choose GP as a career option. In the present study we investigated the profile of medical students in terms of their decisions regarding specialization and the possible association of career choices different from GP with the status of undergraduate training regarding GP. METHODS: The sample consisted of final year students in the Medical School of the University of Athens, Greece. Students filled in a self-reported questionnaire focusing on medical specialization, and GP in particular. RESULTS: Response rate was 82.5% with 1021 questionnaires collected, out of 1237 eligible medical students. Only 44 out of the 1021 (4.3%) respondents stated that GP is -or could be- among their choices for specialty. The most popular medical specialty was General Surgery (10.9%), followed by Cardiology (9.6%), Endocrinology (8.7%) and Obstetrics-Gynaecology (8.3%). The most common criterion for choosing GP was the guaranteed employment on completion of the residency (54.6%) while a 56.6% of total respondents were positive to the introduction of GP/FM as a curriculum course during University studies. CONCLUSION: Despite the great needs, GP specialty is currently not a career option among undergraduate students of the greater Medical University in Greece and is still held in low esteem. A university department responsible for undergraduate teaching, promotion and research in GP (where not available) is essential; the status of undergraduate training in general practice/family medicine seems to be one of the most important factors that influence physician career choices regarding primary care specialties.
