Eating at restaurants, at work or at home. Is there a difference? A study among adults of 11 European countries in the context of the HECTOR* project.

BACKGROUND/OBJECTIVES: To compare macronutrient intakes out of home-by location-to those at home and to investigate differences in total daily intakes between individuals consuming more than half of their daily energy out of home and those eating only at home. SUBJECTS/METHODS: Data collected through 24-h recalls or diaries among 23 766 European adults. Participants were grouped as 'non-substantial', 'intermediate' and 'very substantial out-of-home' eaters based on energy intake out of home. Mean macronutrient intakes were estimated at home and out of home (overall, at restaurants, at work). Study/cohort-specific mean differences in total intakes between the 'very substantial out-of-home' and the 'at-home' eaters were estimated through linear regression and pooled estimates were derived. RESULTS: At restaurants, men consumed 29% of their energy as fat, 15% as protein, 45% as carbohydrates and 11% as alcohol. Among women, fat contributed 33% of energy intake at restaurants, protein 16%, carbohydrates 45% and alcohol 6%. When eating at work, both sexes reported 30% of energy from fat and 55% from carbohydrates. Intakes at home were higher in fat and lower in carbohydrates and alcohol. Total daily intakes of the 'very substantial out-of-home' eaters were generally similar to those of individuals eating only at home, apart from lower carbohydrate and higher alcohol intakes among individuals eating at restaurants. CONCLUSIONS: In a large population of adults from 11 European countries, eating at work was generally similar to eating at home. Alcoholic drinks were the primary contributors of higher daily energy intakes among individuals eating substantially at restaurants.

Harmonisation of food categorisation systems for dietary exposure assessments among European children.

Within the European project called EXPOCHI (Individual Food Consumption Data and Exposure Assessment Studies for Children), 14 different European individual food consumption databases of children were used to conduct harmonised dietary exposure assessments for lead, chromium, selenium and food colours. For this, two food categorisation systems were developed to classify the food consumption data in such a way that these could be linked to occurrence data of the considered compounds. One system served for the exposure calculations of lead, chromium and selenium. The second system was developed for the exposure assessment of food colours. The food categories defined for the lead, chromium and selenium exposure calculations were used as a basis for the food colour categorisation, with adaptations to optimise the linkage with the food colour occurrence data. With this work, an initial impetus was given to make user-friendly food categorisation systems for contaminants and food colours applicable on a pan-European level. However, a set of difficulties were encountered in creating a common food categorisation system for 14 individual food consumption databases that differ in the type and number of foods coded and in level of detail provided about the consumed foods. The work done and the problems encountered in this project can be of interest for future projects in which food consumption data will be collected on a pan-European level and used for common exposure assessments.

Serum markers of bone turnover in children and adolescents with classic galactosemia.

PURPOSE: Classic galactosemia is an inherited metabolic disease resulting from galactose-1-phosphate uridyltransferase (GALT) deficiency. Dietary lactose exclusion reverses many clinical manifestations of acute phase of the disease. Unfortunately most of the patients, despite dietary treatment, develop long-term complications among them disturbances of bone mineralization resulting in decrease of bone mineral density (BMD). The aim of our study was to assess bone formation and resorption processes with bone turnover markers in children and adolescents with galactosemia. MATERIALS AND METHODS: We studied 62 galactosemic children (mean age+/-SD 5.9+/-2.7 years) and adolescents (mean age+/-SD 15.6+/-2,4 years). The clinical diagnosis had been confirmed by the absence of GALT activity in erythrocytes. All patients were diagnosed in the neonatal period and had good dietary control. Healthy children (n=70) were the reference group. Serum osteocalcin (OC), bone alkaline phosphatase (BALP), collagen type I crosslinked C-telopeptide (CTX-I), 25(OH)D metabolite of vitamin D were determined by ELISA assays. RESULTS: We observed similar mean values of bone formation markers in children with galactosemia as compared to the age-matched controls. The level of bone resorption marker CTX-I in these patients was lower by about 20% (p<0.001) than in healthy children. On the contrary we obtained slightly higher values of CTX-I in adolescents with galactosemia in comparison to the age-matched controls. In these patients the values of OC and BALP were significantly higher than in healthy adolescents (111.8+/-52.1 microg/L versus 82.3+/-43.0 microg/L, p<0.02; and 95.4+/-45.7 U/L versus 72.6+/-40.6 U/L, p<0.05 respectively). CONCLUSION: Our results suggest that bone turnover in galactosemic patients elevates from childhood to adolescence, whereas in healthy individuals there is a decline during aging. Further studies on adults with galactosemia are necessary to assess bone status in these patients.

Policy options for responding to the growing challenge from obesity (PorGrow) in Poland.

To explore the perspectives of stakeholders towards a range of policy options to respond to obesity in Poland, a multi-criteria mapping method was used. During structured interviews, stakeholders were invited to appraise policy options by reference to criteria of their own choosing. They also provided relative weightings to their criteria, generating overall rankings of the policy options in relation to each other. Efficacy, feasibility and societal benefits were the groups of criteria deemed most important. There was most consensus in favour of options related to health education, particularly in schools, compared with options that aimed at modifying the environment to prevent obesity, i.e. options around physical activity, modifying the supply and demand for food products, and information-related options. There was little support for technological solutions or institutional reforms. There was broad consensus that to reverse the rising trend in the incidence of obesity, it will be necessary to implement a portfolio of measures, but options related to behaviour change through education are most highly regarded. It will also be necessary to invest in improved surveillance and monitoring of Polish dietary practices, levels of physical activity and obesity in terms of data on height, weight and body mass indexes.

Comparison between household budget survey and 24-hour recall data in a nationally representative sample of Polish households.

OBJECTIVE: Household budget survey (HBS) data are used regularly for nutritional epidemiological purposes. The validity of HBS data, however, is not well established. The aim of this project was to compare HBS and individual nutrition survey (INS) data in a nationally representative sample of Polish households. DESIGN: Estimates of food consumption and nutrient intake were compared between household food acquisition data collected over 1 month and a single 24-hour recall collected from every household member in a nationally representative sample of Polish households surveyed between September and November 2000. To facilitate the comparison, INS food consumption data excluded food eaten away from home and were modified using a computer program to estimate food 'as purchased' (including disaggregation of recipe data) and to allow for wastage. SETTING: Poland. SUBJECTS: Participants were 3716 individuals in 1215 households (representing co-operation rates of 86.2% and 89.2%, respectively). RESULTS: Good agreement was shown between median estimates of foods such as potatoes, vegetables (including processed), meat, meat products and poultry, and animal fats (excluding butter), but agreement was poor for bread and rolls, fruit, vegetable fats and oils, eggs and six other food groups. Estimates of energy and nutrient intake were within +/-10% with the exceptions of polyunsaturated fats, potassium and vitamin C. CONCLUSIONS: Possible reasons for differences in findings between the two surveys include survey bias (e.g. social approval bias leading to overreporting of fruit), seasonal variations (e.g. high potato purchases between September and November) and aspects of the methodology (e.g. HBS data were based on records collected over 1 month, whereas 24-hour recall data were based on recalls collected from all household respondents on only 1 day and averaged for each household type). HBSs provide useful data for epidemiological research, but findings need to be interpreted in the light of other data regarding consumption, and numerous factors that may affect consumption need to be taken into account.

Neonatal hypothyroid screening in monitoring of iodine deficiency and iodine supplementation in Poland.

UNLABELLED: Neonatal hypothyroid screening in Poland is standardised and all newborns screening data are registered in central data base in the National Institute of Mother and Child. About 400,000 newborns are screened per year for hypothyroidism (TSH) and phenylketonuria (PKU). Unfortunately, obstetric clinics still use antiseptics that contain iodine. According to our data 71% of clinics used iodine in 1998 (58% iodine tincture and 13% povidone iodine) and 58.2% (35.4 iodine tincture and 13% povidone iodine) in the year 2000. Presence of iodine resulted in over 3 times increase of a percentage of TSH levels over cut off, increasing the number of false positives in the hypothyroid screening. Analysis of TSH distribution for iodine containing and iodine free hospitals gave totally different estimation of iodine deficiency according to WHO criteria. In the group of iodine free hospitals 24 regions were classified as not deficient, 9 regions were borderline with a fraction of TSH levels over 5 mlU/l of 3-5%. 10 regions could not be analysed because all hospitals declared use of iodine. In the second group all regions were iodine deficient. TSH distribution since 1994 shows significant decrease of percentage of TSH levels over cut off from 2.23% in 1994 to 0.16 in 1997 and to 0.12 in 2000. These changes are most probably connected with successive introduction of iodine supplementation which became obligatory in 1997 and suggest that iodine supplementation covers iodine requirements during pregnancy. CONCLUSIONS: Iodine deficiency and iodine supplementation in Poland can be studied using TSH blood spot newborn screening results in correlation with data on interfering factors and in reference to modified criteria for the analytical test and the population. To reduce false positive rate in neonatal hypothyroid screening iodine containing antiseptics, particularly iodine tincture, should be withdrawn from all obstetrics clinics in Poland.

Project of the countrywide data collecting system for neonatal hearing screening programme in Poland.

Neonatal hearing screening is becoming a standard of care in increasing number of hospitals and outpatient departments in Poland. A project of central data collecting system applicable to a neonatal hearing screening programme has been elaborated as a preparation to introducing a countrywide screening programme. The data collecting system will be based on the currently existing central system for the registration of neonatal screening tests for metabolic diseases. Data on risk factors for hearing loss and hearing screening test results will be collected. A central data collecting system for a neonatal hearing screening programme will increase the efficiency of the screening programme and facilitate epidemiological studies.

[The impact of iodine prophylaxis programme on thyroid gland morphology and function in children and adolescents from the Mazowieckie Voivodship]. / Ocena wplywu profilaktyki jodowej na morfologie i funkcje tarczycy u dzieci i mlodziezy z ternu województwa mazowieckiego.

The project was realised within the multicentre research programme no PBZ038-08. In all, 2967 children aged 11-18 years were examined, including 1712 girls and 1255 boys. The tested children came from the Mazowieckie Voivodship. Each child was assessed by thyroid ultrasound examination and the level of TSH, FT4 hormones, antithyroid antibodies ATM and ATGL in the blood serum. The level ofFT3 hormone in blood serum was assessed in every fourth child. The aim of this work was to determine the influence of obligatory iodine preventive treatment programme on the morphological and functional status of the thyroid gland in children and teenagers from the Mazowieckie Voivodship. The tested children were divided into three groups: 525 children examined in 1997, living in an area of moderate iodine deficiency, 1477 children tested in 1998 after a few months of iodine supplementation and 965 children examined in 1999 who were well supplemented by iodine longer than one year. The average thyroid volume and the incidence of focal changes in the thyroid gland were determined by ultrasonography, the mean of the TSH, FT4, FT3, hormone level was defined in blood serum in girls and in boys examined in consecutive years. In children tested in 1999 a reduction of the average thyroid volume and a statistically significant decrease of the percentage of children with goitre and with focal changes in the thyroid gland were observed in comparison to children tested in 1997. The results depended on iodine prophylaxis. A statistically significant lower level of FT3 hormone in blood serum was recorded in children tested in 1999 than in 1997. The largest number of children with high levels of ATM and ATGL antibodies in blood serum, exceeding 100 IIJ7ml, were found in 1997 (ATM in 8.6% of cases, ATGL in 17.3% of cases). The high level of ATGL antibodies was observed more frequently in children tested in 1999 than in 1998.

[Evaluation of the usefulness for neonatal mass screening in light of 35 years personal experience]. / Ocena przydatnosci badan przesiewowych u noworodków w swietle 35 lat doswiadczen wlasnych.

The results and the significance of neonatal mass-screening programmes for inborn errors of metabolism, conducted by the National Research Institute of Mother and Child (NRIMC), are discussed. As the first in Poland, in 1964, mass-screening for phenylketonuria (PKU) was introduced. The BIA-Guthrie test was used. Other Guthrie tests (GBIA) were applied in homocystinuria, tyrosinemia, histidinemia and leucinosis (Maple Syrup Urine Disease-MSUD). In the middle of the 60. the Beutler and Baluda test was introduced for galactosaemia, as well as the Efron urine test in infant screening for different inborn errors of metabolism. In the middle of the 70., neonatal mass-screening for cystic fibrosis (CF, mucoviscidosis) was started. Meconium tests and the sweat test with ion selective chloride electrode were used. Apart from inborn errors of metabolism, we also introduced a screening programme for neuroblastoma in which vaniline mandelic acid (VMA) in urine was estimated and for congenital hypothyroidism were TSH level was assessed. The results of screening are shown in the tables and in the figures. In our opinion the best clinical results are obtained with screening for congenital hypothyroidism and for PKU, since very early detection and treatment in these diseases prevents severe mental retardation. We therefore consider that both these screening programmes should be treated as obligatory examinations in all neonates. Taking into consideration the fact that there are different types of hyperhenylalaninemias, the principles of differential diagnosis are discussed. Molecular genetic investigations, carried out in the NRIMC Department of Genetics proved to be a very important procedure in the verification of diagnosis of different mutations. The authors also discuss the problem of dietary treatment duration in PKU. In our opinion the hypophenyloalanine diet regimen in girls, should not be discontinued during adolescence, since there is the problem of maternal PKU and the possibility of foetal damage. The results of our own investigations of maternal PKU are discussed. The significance of mass-screening for galactosemia is still under discussion. In our opinion, mass-screening for galactosemia is not useful and we have discontinued it. Selective screening has been started combined with molecular genetic studies in high risk families. In the future, we plan to prepare guidelines on the principles of diagnosis and treatment of galactosemia in children and women in the reproductive age. Mass-screening for cystic fibrosis is also still under discussion. The results of the early screening programmes were not satisfactory and the tests were discontinued. In 1998, after reorganisation of the whole system, CF screening, using tripsin-radioimmune assays, was started again. The new screening programme is combined with molecular genetic investigation of different mutations. It is still too early to assess the importance and success of this CF mass-screening programme. We decided to discontinue the screening for homocystinuria, histidinemia, tyrosinemia, leucinosis and for neuroblastoma, since these programmes did not comply with criteria of mass-screening. In 1997, major reorganisation of screening programmes for inborn errors of metabolism, at NRIMC, was undertaken. The Guthrie test for PKU was changed to a quantitative colorimetric method. The immuno-luminometric method is used for TSH estimation. The whole system is based on complete computer control of all the steps of screening, from blood sampling on filter paper until the final diagnosis. The advantages of this modern system of organisation of the screening programme are discussed.

[Chronicled report on the period from May 1 to September 27, 1989. Discussion of risk factors]. / Raport etapowy za okres od dnia 1 maja do dnia 27 listopada 1989. Omo'wienie uzyskanych wyniko'w.

The Institute of Mother and Child was invited in 1988 by professor J. Nauman to his Chernobyl program, so as to inspect children born after Chernobyl accident, particularly these born in first days following the accident dated 26 april 1986. The central part of Poland is covered with screening for congenital PKU and hypothyroidism therefore all children had estimated TSH-spot levels between 3rd and 5th day of life. So as to control the present state of general health and thyroid state in the study group a questionnaire with a letter to parents explaining the aim of the inquiry was sent to the parents (see addenda). About 14000 letters were send from which around 12000 responses were returned to the Institute. From informations received this way we draw the preliminary conclusion that no significant damage in health of these children or their siblings can be found. About 20% of the mothers admitted taking the Lugol solution in a last day of pregnancy. However it should be taken into account that these data were collected 2 years after the accident and are not fully reliable. In the period 1989-1990 a group of 1912 children (938 boys and 974 girls) was called to the Department of Endocrinology of the Institute and inspected. The age was from 2.9 to 4.2 years. All children had screening TSH-spot test result negative (below 30 microIU/ml). General health state The general health state of the children inspected was good. Only 33 of them (1.7%) had various congenital malformations what is not different from general population of polish children. Mental development was in 1897 cases normal, in 15 cases IQ was decreased and the score varied from 75 to 80 according the Brunet-Lezine scale. Average physical development was normal. Body height evaluated in standard deviation score (SDS) was as follows: SDS = 0.0 in 359; SDS = +0.9 +/- 0.6 in 906 and SDS = -0.5 +/- 0.3 in 647 cases. Thyroid state At 1904 inspected and analytically estimated children the thyroid function was normal. Only in 8 cases (0.8%) a goiter was found with euthyroid state. Analytical data were as follows: total T4 serum level = 111.8 + 43.1 nmol/l (50.4-171.9), ref. value: 50.1-170.0 nmol/l; total T3 serum level = 2.5 +/- 0.4 nmol/l (ref. value 1.9-3.6); TSH serum level 4.4 +/- 2.6 uIU/ml. Trace amounts of antithyroid membrane antibodies were found at 12 children (0.63%) of the group in serum diluted 1:250.(ABSTRACT TRUNCATED AT 400 WORDS)
