[Nutrient intake and nutritional status of 4-10-year-old Hungarian children]. / 4­10 éves magyar gyermekek tápanyagbeviteli és tápláltsági állapotának felmérése.

INTRODUCTION AND OBJECTIVE: The growing trend of childhood obesity is a major public health issue. Collaborations between medical and healthcare professionals, preventive and health preservative programs, dietary habit and nutrient intake studies are indispensable. METHOD: A representative study has been performed among 4-10-year-old Hungarian children by gender, age, size of settlement and region. The study included 733 assessable questionnaires and 666 dietary records. Data on children's eating habits were collected by using the internationally recommended three-day dietary record method. Body weight and height measurements were taken for each child to determine nutritional status. Data were analyzed with statistical methods. RESULTS: The rate of overweight and obesity is 23%. Energy intake differs significantly between body mass index groups. The children's fat intake is excessive (34.2 energy%), the saturated fatty acid intake exceeds the recommended 10 energy%, omega fatty acid ratio is disadvantageous and the children's cholesterol intake is high. The average energy from carbohydrates is below the recommended 57 energy%, from added sugar it is 11%, which affects 52% of the children. Their low fibre intake (19.4 g/day) is due to low fruit, vegetable (263 g/day) and whole grain consumption. Of the micronutrients, sodium intake is 3-4 times higher than the recommended. In 35% of the children, the calcium intake is below the critical threshold, due to unfavourable milk and milk product consumption (290 g/day). Vitamin D intake was low in 98-100% of the children. CONCLUSION: Compared to the results of other European and national studies performed among children, adolescent and adults, the nutritional status and nutrient intake of our sample is unfavourable. Comprehensive intervention, education of the children with the involvement of their parents is essential to reduce obesity. Orv Hetil. 2023; 164(14): 533-540.

[Nutrition assessment of 0-3-year-old infants and toddlers with particular focus on macro- and micronutrient intake]. / 0­3 éves korú csecsemok és kisdedek táplálkozási szokásainak felmérése, különös tekintettel a makro- és mikronutriens-bevitelre.

Introduction: Recent research findings support the assumption that the development of chronic diseases in adults is greatly influenced by the supply of nutrients in the uterus and the nutrition, nourishment of the early, toddler ages. Aim: The aim of the present study was to evaluate the nutritional habits of infants and toddlers aged 0-3 in Hungary, and to identify the most typical problems of their nutrition, to get to know and provide the necessary data for the modification and modernization of feeding/nutrition recommendations for infants and young children in Hungary. Method: The study was carried out with the professional coordination of the Hungarian Dietetic Association (MDOSZ) in the framework of industry research between June and August 2015, in the 0-3-year-old population, in the cities Budapest, Debrecen, Gyor, Szeged and Pécs. The survey was conducted with anthropometric measurements and validated by three-day dietary log templates. Results: 18.6% of infants aged 4 to 12 months (n = 220) had values below 10th percentile, 10% were between 85-97th percentiles and 3% were above 97th percentile. 15% of children aged 12-24 months (n = 227) had a body mass index (BMI) below 10th percentile (underweight), 14% were between 85-97th percentile (overweight) and 2.6% had BMI over the 97th percentile (obese). 70% of 25-36-month-old children (n = 184) had normal BMI, 4% were overweight, 2% obese, 24% underweight. Based on the Hungarian reference value, 10.9% of the 4-12-month-old children, 20% of the 1-2-year-olds, 47% of the 2-3-year-olds were in high protein intake group. However, compared to the 2013's reference values of the EFSA (European Food Safety Authority) recommendation, 100% of the children belong to the high protein intake group in all age groups. Conclusion: Although the EFSA recommendation - based on the WHO/FAO/UNU macro- and micronutrient intake values in 2007 - defines the recommended intake quantities, the results in the sample did not support its overall reliability.

Prevalence of underweight, overweight and obesity on the basis of body mass index and body fat percentage in Hungarian schoolchildren: representative survey in metropolitan elementary schools.

BACKGROUNDS/AIMS: The incidence of obesity is increasing dramatically not only among adults, but also in children. The purpose of the survey was to assess the age- and gender-specific anthropometric data of children between the ages of 7 and 14 years who attended elementary schools in Budapest. METHODS: A cross-sectional study was performed in 2005. Altogether 1,928 students (1,002 boys and 926 girls) were recruited from the schools. The representative sampling sites were selected randomly. Height and waist circumference were measured, other data were analyzed by an 8-polar bioelectrical impedance procedure. Statistical analysis was carried out using SPSS 11 for windows. RESULTS: On the basis of body mass index (BMI), prevalence of underweight, overweight and obesity were 5.1, 18.1 and 7.4% for boys and 6.8, 19.6 and 6.3% for girls, respectively. On the basis of body fat percentage (%BF), prevalence of obesity was 17.9% for boys and 12.8% for girls. Forty nine percent of boys and 28% of girls categorized as overweight by BMI were obese according to their %BF. The difference in waist circumference between individuals categorized by BMI as normal and obese was 24.7 cm for boys and 20.5 cm for girls. Between those categorized as non-obese and obese by %BF, the difference was 17.3 cm for boys and 16.4 cm for girls. Normal and overweight boys and girls with high %BF had significantly higher waist circumferences than their counterparts with normal %BF. This means that many obese children may escape detection as obese, if classified as overweight on the basis of BMI alone. CONCLUSION: Results appear to underline that in addition to BMI, the determination of the %BF and waist circumference is important in epidemiological studies to identify obese subjects.

Turning dilemmas into opportunities: a UNU/SCN capacity development network in public nutrition in Central and Eastern Europe.

Capacity development in nutrition is a process whereby individuals, groups, institutions, organizations and societies enhance their abilities to identify and meet challenges in a sustainable manner. To address these issues, in 2001 the UN System Standing Committee on Nutrition (SCN) established a Working Group on Capacity Development under the joint coordination of the United Nations University (UNU) and the International Union of Nutritional Sciences. Several regional professional networks have developed under this working group, the latest for the Central and Eastern Europe (CEE) countries. Ten CEE countries formed a network in 2006 and identified major nutritional challenges in the region, which included: irregular meal patterns; low consumption of fruits/vegetables, milk products and fish; low intake of some micronutrients; and high intakes of fat, sugar and salt. Public policies in nutrition were either weak or absent. Some countries had recently developed nutrition plans. Higher education in nutrition was seen as very important for public nutrition work by professionals in the region, who considered it a prerequisite for reversing the negative trend of the nutrition transition. The network will continue to work on issues that are still not covered adequately. Its activities to date and prospects for the future are assessed against ten principles for good capacity development suggested by the United Nations Development Programme.

[Is there a unique measuring method to assess obesity?]. / Van kitüntetett méromódszer az elhízás megállapítására?

UNLABELLED: In the literature there is not available a uniformly accepted method for assessing the degree of obesity. AIM: To determine how far insulin resistance, serum levels of leptin and resistin are altered in persons categorized on the basis of body-mass index (BMI), body fat percentage, and abdominal circumference. METHODS: 101 volunteer boys and 115 girls participated in the studies. Body height was measured, body mass, abdominal circumference, and body composition were determined by InBody3 bioimpedance instrument. Body mass index and body fat percentage were calculated by the instrument. Concentrations of serum glucose, insulin, leptin, and resistin were determined. Insulin resistance was calculated using the homeostasis model: HOMA IR . RESULTS: Body fat percentage, serum levels of leptin and resistin were significantly higher in girls than in boys. Increases in BMI, body fat percentage, and abdominal circumference were associated with the significant elevation of both HOMA IR and serum leptin concentrations. In overweight boys categorized by body fat percentage as obese the serum leptin concentrations were significantly higher than in their non-obese counterparts. CONCLUSION: Determination of body composition would be important concerning the follow-up of biochemical changes occurring in the body during the course of both epidemiological studies and nutritional interventions.

[Effects of oligofructose containing diet in obese persons]. / Az oligofruktóz hatásának vizsgálata elhízottakban.

UNLABELLED: In the treatment of obesity the introduction of a low-calorie diet is a fundamental requirement. The enhancement of the fiber content of food causing satiety may contribute to the observation of dietary prescriptions. Oligofructoses belong to the group of dietary fibers. AIM: To study the effects of the consumption of a low-energy diet (2,000 kcal/day) completed with Jerusalem artichoke concentrate in obese adolescents and adults. METHODS: 12 obese students (6 boys and 6 girls) and 6 obese women were put on a low-calorie regimen for 12 weeks, whereas 16 obese students (10 boys and 6 girls) and 17 obese women consumed the same low-calorie diet completed with Jerusalem artichoke concentrate containing 14 g/day oligofructose. Sensation of fullness was estimated. In addition to anthropometric parameters serum biomarkers of lipid and carbohydrate metabolism and adipokines were determined. RESULTS: The consumption of the low-calorie diet completed with Jerusalem artichoke concentrate resulted in a diminished sensation of hunger. Body mass index and body fat percentage decreased significantly. In girls and women, the serum levels of triglycerides were also significantly reduced and the rate of insulin resistance estimated on the basis of homeostasis model assessment was also improved. CONCLUSIONS: The results of this pilot study appear to demonstrate that the Jerusalem artichoke concentrate produced by a new technology can be a promising component of future diet therapy.

Lifestyle of Hungarian adolescents--observations among metropolitan secondary school students.

BACKGROUND/AIMS: Obesity among adolescents is a significant and global disease which requires early prevention. The development of overweight and obesity depends not only on genetic components but also on lifestyle. The objective of the survey was to study the lifestyle of 15- to 19-year-old secondary school students in Budapest. METHODS: Students (n = 1,273, 670 boys, 603 girls) were asked to complete questionnaires about their leisure activities, physical exercise, eating habits and knowledge of nutrition. The response rate was 45.2%. RESULTS: Three-quarters of the secondary school students lived a sedentary life and more than half were dissatisfied with their body weight. More than 40% of the girls had been on a slimming diet at least once. Half of the students regularly consumed vitamin and/or mineral supplements. Nearly 25% of the adolescents did not have breakfast and nearly 60% of the school-leavers smoked regularly. CONCLUSIONS: Coordinated cooperation is necessary among stakeholders to support the aim of changing nutritional and exercise behavior of adolescents.

[Association between birth weight and childhood obesity in a Budapest metropolitan survey]. / A születési testtömeg és a gyermekkori elhízás kapcsolata egy fôvárosi felmérés alapján.

INTRODUCTION: According to epidemiological investigations, association between birth weight and overweight and obesity in childhood/adolescence is ambiguous. AIM: The purpose of the study was to investigate the association between birth weight and overweight and obesity in childhood and adolescence. METHODS: Birth and actual anthropometric data of school children and secondary school students from metropolitan schools were analyzed. Overweight/obesity were established by standardized (sex, age) body mass index, and obesity also by body fat percent. RESULTS: Data of 1,334, 7- to 19-year-old children and adolescents (725 boys and 609 girls) were evaluated. Prevalence of overweight/obesity was similar in the case of persons with low (19.36%) and normal birth weight (18.96%), while in the case of persons with high birth weight this rate was 25.98%. Based on body fat percent, the prevalence of obesity in the latter group was also higher than in groups with low and normal birth weight (18.11% vs. 12.89% and 12.66%). CONCLUSIONS: Among macrosomic babies the rate of overweight and obesity is higher than among normal or low-birth-weight babies, particularly in childhood.

[Methods for the assessment of adolescent obesity in epidemiological studies]. / Az epidemiológiai vizsgálatokban alkalmazható néhány méromódszer a serdülokori elhízás megítélésére.

INTRODUCTION: The incidence of obesity is increasing dramatically not only among adults, but also in the child population. OBJECTIVE: Comparison of different anthropological methods. METHODS: The authors evaluated the data of 654 boys and 584 girls (age 15-19 years). Body height and waist circumference were measured, body composition was determined using InBody3.0 bioimpedance instrument. Body mass index and body fat percentage were calculated by the instrument. RESULTS: On the basis of age and gender specific diagnostic criteria for body mass index, incidence of leanness, overweight and obesity in the boys' group were 6.7, 15.9 and 4.1%, respectively. In the girls' group the respective figures were 7.2, 7.9 and 1.9%. On the basis of body fat percentage, 5.1% of boys and 16.2% of girls were obese, whereas on the basis of data for waist circumference, visceral obesity occurred in 10.5% of boys and 7.9% of girls. In the overweight groups 10.5% of boys and 77.0% of girls were obese on the basis of body fat percentage, whereas taking into consideration the values of waist circumference, 38% of boys and 55% of girls could be regarded as obese. CONCLUSIONS: The determination of body composition is of utmost importance in obesity screening and in the follow-up slimming diets. In addition to this, simple and inexpensive waist circumference measurements should be performed in each instance.

Lifestyle of school children: representative survey in metropolitan elementary schools. Part one.

BACKGROUND/AIMS: The prevalence of overweight and obesity among school children is increasing dramatically. Obesity is multifactorial and depends on lifestyle as well as genetic components. The purpose of the survey was to investigate the lifestyle of 7- to 14-year-old children attending elementary schools in Budapest. METHODS: The research was questionnaire-based. Children were asked to answer questions about their leisure activities, physical exercise, nutritional, eating, and smoking habits. RESULTS: Many children live a sedentary life and are dissatisfied with their body weight. One in 5 boys and 1 in 3 girls have been on a slimming diet at least once. About two-thirds of the children regularly consumed vitamin and/or mineral supplements and at the same time just over half of them knew how much fruit should be eaten daily. School children in the upper classes did not eat 5 times a day. More than 5% of the 11- to 14-year-old boys and more than 10% of the girls smoked regularly. CONCLUSIONS: According to our results, the unfavorable lifestyle of the great majority of Hungarian school children may have implications for their health during adulthood.

Dietary habits of school children: representative survey in metropolitan elementary schools. Part two.

BACKGROUND/AIMS: The aim of this study was to investigate the eating habits and the nutrient intake of 11- to 14-year-old school children as part of a representative nutrition and health survey in primary schools in Budapest. METHODS: A food frequency questionnaire of 875 school children, aged from 11 to 14 (449 boys and 426 girls), was recorded and evaluated. Energy and nutrient intake of 235 children (124 boys and 111 girls) was calculated in parallel by 3-day dietary record. RESULTS: The average energy intake (MJ) was appropriate (boys: 10.40 +/- 1.89; girls: 9.18 +/- 1.50); protein and fat intake was somewhat higher than the Hungarian recommended dietary allowances. Sodium intake was alarmingly high. The intake of calcium and vitamin D was inadequate. The intakes of zinc, chromium, retinol, folate for both genders, and iron in the case of girls were insufficient. The daily consumption of milk and dairy products was deficient, that of vegetables and fresh fruits was rather low, while the frequency of consumption of sugar-sweetened beverages, chips, sticks and fast foods was high. CONCLUSIONS: Nutrition intervention programs should be launched among Hungarian school children.

[Dietary survey in Hungary, 2003-2004. Micronutrients: vitamins]. / Táplálkozási vizsgálat Magyarországon, 2003-2004. Mikrotápanyagok: vitaminok.

The 3rd Hungarian National Nutritional Survey was carried out as a part of the National Population Health Study and the data collection was done in November/December of 2003. The survey comprised a sample of adults above 19 year of age, the dietary questionnaires of 1179 people could be evaluated. The results of energy and macro-nutrient intake were published in 2005, and the results of the mineral intake in 2007, in the Hungarian Medical Journal. This paper focuses on the intake of vitamins. For the evaluation of the results authors used the data of the two previous national surveys, data of some dietary studies of other countries, and the home and international intake recommendations. In respect of the data found in the present survey, it is a favourable trend that the intake of vitamins retinol equivalent, B1 , B6 and B12 , and niacin, as well as biotin was sufficient both in case of men and women, together with adequate vitamin E intake for men. However the intake of vitamin B2 , C, D, together with pantothenic acid and folic acid of both men and women did not meet the criteria of the Hungarian recommendations, besides the vitamin E intake of women was insufficient as well. In Hungary the intake of vitamin D, biotin, folic acid and pantothenic acid was measured at first at this National Dietary Survey. The authors vigorously stress the importance of the varied and healthy nutrition in the adequate vitamin supply of the population.

[Hungarian national dietary survey, 2003-2004. Micronutrients: mineral salts]. / Táplálkozási vizsgálat Magyarországon, 2003-2004. Mikro-tápanyagok: ásványi sók.

In the course of the 3rd national nutritional survey data were collected in 2003, and the paper on the energy and nutrition intake of a sample group consisting of 1179 people all aged above 19, was published in the Hungarian Medical Journal (Vol. 146, No. 34, 2005). The present paper focuses on one group of micronutrients, namely the minerals' intake. The authors evaluated the results mainly in comparison with the data of the two previous Hungarian national surveys, and the international and national recommendations. The average magnesium intake was considered adequate in both sexes, while iron, zinc and copper intakes also met the recommended level in men. On the other hand, the insufficient calcium and the excessive phosphorus intakes, as well as the disproportionate calcium-phosphorus ratio in both sexes are unfavourable facts. The adverse results include insufficient iron, zinc and copper intake in women and the excessive sodium intake in both sexes, as well. The authors emphasize the importance of spreading the principles of healthy nutrition as well as co-operating with the food industry in order to prevent the occurrence of mineral nutrients deficiency.

Assessment of cardiovascular risk factors among Hungarian university students in Budapest.

BACKGROUND/AIMS: The lack of data regarding cardiovascular risk factors among university students in Hungary prompted us to undertake a cross-sectional pilot study in students at Semmelweis University, Budapest. METHODS: A total of 264 students (78 males, mean age 21.4+/-2.6 years, and 186 females, mean age 21.2+/-2.6 years) participated in the study. Anthropometric measures, blood pressure and serum lipid parameters were investigated. The relationship between body mass index and cardiovascular disease risk factors were analyzed. RESULTS: The occurrence of overweight and abdominal obesity was significantly higher in the male group. The mean serum lipid values were within the acceptable range for both genders; however, in a significantly greater number of male than female students the HDL-cholesterol concentration (<1 mmol/l) was in the low range. High lipoprotein(a) values were seen in 33% of the male and 22.6% of the female students. In both groups of students the body mass index exhibited a positive correlation with waist circumference, total cholesterol, LDL-cholesterol, apolipoprotein B (p<0.01), and systolic and diastolic blood pressure. In the female students there was an inverse correlation between body mass index and HDL-cholesterol concentrations. CONCLUSIONS: The anthropometric and lipid parameters of the student population studied were more favorable than those for an age-matched Hungarian youth population. Nevertheless, the higher occurrence of elevated blood pressure, overweight, abdominal obesity, lower HDL-cholesterol in the male group should be regarded as a warning sign, all the more since their diet was imbalanced and their knowledge in this field was incomplete. The results of our preliminary study point out the importance of teaching nutrition more efficiently, not only during university training but also at an earlier age.

[Dietary survey in Hungary, 2003-2004]. / Táplálkozási vizsgálat Magyarországon, 2003-2004.

The third Hungarian national dietary survey was conducted in 2003-2004. This publication describes the first part of the energy and nutrient intake findings in a sample consisting of a population of 1179 persons over 19 years of age (energy and macro nutrients). Energy and nutrient intake values were calculated based on 3 x 24- hour dietary records filled out by the subjects themselves. The authors evaluated the results in light of the two previous dietary surveys in Hungary and the Hungarian and international reference intake data. The total fat intake found in this survey lower than the previous data marks a favourable development, just as the higher unsaturated fatty acid and lower saturated fatty acid energy percent, and furthermore the lower cholesterol intake level. The favourable developments include further a polyunsaturated/saturated fatty acid ratio considerably higher than that obtained earlier (the values conforming to the international reference data), a higher carbohydrate energy percentage, as well as lower added sugar energy percentage, this latter being in the recommended range. The overweight ratio in men was 58.9%, while the female value was 49.5%, not much different from the previous survey data.

Effect of enterally administered n-3 polyunsaturated fatty acids in acute pancreatitis--a prospective randomized clinical trial.

BACKGROUND: In acute pancreatitis (AP) administration of n-3 polyunsaturated fatty acids (PUFAs) might change the course of the disease through modulation of eicosanoid synthesis. PATIENTS AND METHODS: In a prospective, randomized clinical trial from 28 patients with moderate-severe AP, 14 received n-3 PUFAs (fish oil) enterally (3.3g/day for 5-7 days). Measurement of erythrocyte superoxide-dysmutase (SOD) activity, serum total antioxidant status (TAS), vitamin A and E, fatty acids, C-reactive protein, transthyretin concentrations were performed at admission, day 3, 7 and 14. RESULTS: The n-3 to n-6 LCPUFA ratios increased significantly in serum lipids of the patients receiving n-3 PUFA supplementation, whereas remained unchanged in the controls. Supplementation resulted in significant decrease in length of hospitalization (13.07+/-6.70 vs. 19.28+/-7.18 days, P<0.05) and jejunal feeding (10.57+/-6.70 vs. 17.57+/-10.52, P<0.05). Complications developed in 6/14 (42%) of treated and 9/14 (64%) of control patients. The SOD activity was significantly higher at day 3 in the supplemented group (P<0.05), but there were no significant differences between the two groups in other antioxidants and acute phase reactants. CONCLUSION: The use of enteral formula enriched with n-3 PUFAs in the treatment of AP seems to have clinical benefits based upon the shortened time of jejunal feeding and hospital stay.

Representative study for the evaluation of age- and gender-specific anthropometric parameters and blood pressure in an adolescent Hungarian population.

BACKGROUNDS/AIMS: To assess the age- and gender-specific anthropometric parameters and blood pressure in Hungarian adolescents. METHODS: A cross-sectional study was performed between 1997 and 2000. Altogether 6,345 secondary school students (aged 15-18 years) were involved in the study. The representative sampling sites were selected randomly. In the capital city 3-stage and in the counties 4-stage stratified groups were assigned for the studies. Statistical analysis was performed using SPSS for Windows 9.0. RESULTS: The age- and gender-specific percentile distributions are given with regard to body weight, body height, body mass index (BMI), waist circumference, waist-to-hip ratio and arterial blood pressure values. Elevated blood pressure values were found at the first recording in 14.1% of the boys and in 2.5% of the girls. Since it is well known that the arterial blood pressure (ABP) may exhibit considerable intra- individual fluctuation with time, we therefore categorized normotensive and hypertensive students on the basis of the mean ABP values calculated from data obtained during the course of the three separate consecutive measurement periods at least 2 weeks apart. After that, the incidence of high blood pressure was 7.5% in boys and 1.1% in girls. CONCLUSION: The age- and gender-specific cutoff values thus formed may serve as reference values to assess the risk of developing nutrition-related noninfectious diseases in the future on the basis of the present percentile distribution of BMI. The present study also provides data on the prevalence of hypertension in the 15- to 18-year-old age group.

[Factors influencing lycopene content of foods, and lycopene intake of Hungarian population]. / Az élelmiszereink likopintartalmát befolyásoló tényezôk és a hazai lakosság likopinbevitele.

Lycopene is an acyclic, biologically active carotenoid that constitutes foods, its preventive role in several cancerous diseases have been proved by epidemiological and experimental data. Its beneficial role in maintenance of human health is related to its significant antioxidant properties. Data of dietary lycopene intake of the Hungarian population is not available. The aims of the present complex study were 1) to measure the lycopene content of foods frequently consumed in Hungary, 2) to investigate the effect of agrotechnological procedures and food processing on lycopene content of tomatoes, 3) to estimate the lycopene intake in two groups of the Hungarian population with the use of a three-day dietary record. The best lycopene sources are the raw (5.0-16.0 mg/100 g) and processed tomatoes and tomato products (3.0-80.0 mg/100 g), and also watermelon (3.6-6.2 mg/100 g). The variety of the plants, the growing circumstances, and the weather conditions significantly influence the lycopene content of freshly consumed and processed tomato fruits. Mild technological processes can preserve a considerable amount of the original lycopene content in tomato. The estimated average dietary intakes of the Hungarian children (n=521) and adults (n=205) were 2.98 +/- 4.71 mg/day/capita, and 4.24 +/- 8.47 mg/day/capita, respectively. Optimal climate conditions of Hungary makes possible to produce tomato fruits with high dietary value including significant amount of health protective lycopene. Increased consumption of tomato and tomato products with high concentration of lycopene may improve the antioxidant capacity of human body, and the risk of several cancerous diseases may be reduced.

[Incidence of risk factors in parents with acute myocardial infarction at young age and in their children]. / Kockázati tényezok elofordulása fiatalkori akut myocardialis infarctus miatt kezelt szülokben és utódaikban.

INTRODUCTION: The preliminaries of the cardiovascular diseases can be traced back to the childhood. The authors tried to find relationship between parents with early onset myocardial infarction (AMI) and incidence of risk factors for ischemic heart disease in their children as compared to respective data for families with no incidence of myocardial infarction. METHODS: The study population consisted of 38 persons with early onset AMI myocardial infarction (age < 55 y) and their 66 children, and 38 adult control subjects and their 33 children. In each person arterial blood pressure, body weight, body height, waist circumference were recorded and body mass index (BMI: kg/m2) was calculated. Eating habits and life style practices were recorded in a questionnaire in the case of each participant. Laboratory variables were determined in the blood sera as follows, glucose, triglycerides (Tg), total cholesterol (T-C), HDL-cholesterol, LDL-cholesterol, apolipoprotein-A, apolipoprotein-B, and lipoprotein (a). The atherogenic index (LDL-C/HDL-C) (LDL-cholesterol/HDL-cholesterol) was also calculated. STATISTICAL EVALUATION: Data were evaluated statistically using the SPSS for Windows 9. RESULTS: According to the mean BMI values all groups of parents belonged to the overweight category. The mean cholesterol levels of all adults were in the borderline high category. In males with early onset myocardial infarction sera concentrations of HDL-cholesterol and apolipoprotein-A were significantly lower, whereas triglyceride and atherogenic index were significantly higher than respective data for control parents. In all groups of parents, fasting mean serum glucose concentrations were higher than the reference value, serum total-cholesterol concentrations were in the borderline high category. In the daughter of the parents with early onset myocardial infarction had a higher atherogenic index than that of controls. Eating habits did not essentially differ between case vs. control families. Consumption of milk, dairy products, fruit and vegetables was insufficient in each group. Incidences of smoking for parents and children were 55% and 35% in the myocardial infarction group and 44% and 37% in the control group, respectively. Physical activity was completely insufficient in each group studied. CONCLUSION: Since no considerable differences were seen between the case vs control families in the parameters tested, therefore it is presumed that the offspring born to parents with or without early onset myocardial infarction are at equal risk to develop cardiovascular diseases unless lifestyle practices are profoundly changed.

[Cross-sectional survey on the nutritional and life-style habits of secondary school students in Hungary]. / Hazai reprezentatív felmérés a középiskolás fiatalok táplálkozási és életmódbeli szokásairól.

INTRODUCTION: The national representative survey of secondary school students (age: 15-18 years) was undertaken between 1997 and 2000. The authors presented the data related to the nutritional and life-style habits. METHODS: The data for 6,347 students (48.4% boys and 51.6% girls) were evaluated. The anonymous questionnaire contained inquiries on nutritional rhythm, food frequency, use of vitamin and mineral supplements, smoking, alcohol and drug consumption habits, regular physical activity and family background (qualification, smoking, alcohol consumption). Within the frame of personal interviews the authors collected data on students' history with regard to occurrence of diabetes mellitus, other chronic diseases and in girls the time of the first menstruation. Concerning parents' history the authors collected information on the incidence of hypertension, myocardial infarction, diabetes mellitus, and stroke. STATISTICAL EVALUATION: Data were recorded in Data-Ease database system, in forms of individual records. The individual records were converted to be suitable for the statistical evaluation by SPSS for windows 9 statistical program pack. Data are presented as means and percent distribution. RESULTS: The nutritional rhythm of students was irregular. The daily consumption of milk, dairy products, fruits, fresh vegetables and vegetable dishes was insufficient. Eighty percent of students added extra salt to foods. More than 49% of students regularly consumed some forms of vitamin and/or mineral supplements. Thirty five percent of boys and 30% of girls smoked daily, 14.6% of boys and 5.9% of girls consumed alcohol at least once a week. Fifteen percent of boys and 11% of girls already tried taking drugs at least once. Only 50% of boys and 31% of girls were involved in a regular physical activity. Twenty two percent of fathers and 25% of mothers had university qualifications, whereas intermediate qualifications were recorded in 63 and 59%, lower qualifications occurred in 8 and 13% of parents, respectively. The incidence of smoking was 42% for fathers and 36% for mothers. Weekly alcohol consumption was recorded in 11%, daily consumption in 7% among fathers, the same figures for mothers were 4-4%, respectively. The incidence of hypertension, myocardial infarction, diabetes mellitus, and stroke was 26; 3.4; 5.4 and 1.5% in fathers and 32.9; 4.2; 6.6 and 1.5% in mothers. CONCLUSIONS: The data collected in the complex nutritional hygienic survey revealed serious deficiencies in the nutritional and life style habits of secondary school students. These factors considerably contribute to the unfavorable statistics of nutrition related non-infectious diseases in adulthood.
