Testing Syndromes of Psychopathology in Parent and Youth Ratings Across Societies.

As societies become increasingly diverse, mental health professionals need instruments for assessing emotional, behavioral, and social problems in terms of constructs that are supported within and across societies. Building on decades of research findings, multisample alignment confirmatory factor analyses tested an empirically based 8-syndrome model on parent ratings across 30 societies and youth self-ratings across 19 societies. The Child Behavior Checklist for Ages 6-18 and Youth Self-Report for Ages 11-18 were used to measure syndromes descriptively designated as Anxious/Depressed, Withdrawn/Depressed, Somatic Complaints, Social Problems, Thought Problems, Attention Problems, Rule-Breaking Behavior, and Aggressive Behavior. For both parent ratings (N = 61,703) and self-ratings (N = 29,486), results supported aggregation of problem items into 8 first-order syndromes for all societies (configural invariance), plus the invariance of item loadings (metric invariance) across the majority of societies. Supported across many societies in both parent and self-ratings, the 8 syndromes offer a parsimonious phenotypic taxonomy with clearly operationalized assessment criteria. Mental health professionals in many societies can use the 8 syndromes to assess children and youths for clinical, training, and scientific purposes.

Sex-specific age-related changes of information processing rate indicators during childhood and adolescence.

Despite the relevant findings on non-average information processing rate (IPR) indicators-intelligence relation, and on age-related changes of some of these indicators during aging, the research on sex-specific age-related changes of these indicators during childhood and adolescence are lacking. In a transversal study, 1197 school children (598 girls) aged 8-18 have been individually measured on 5 IPR indicators--two averages (mean_t, median_t) and three non-averages (min_t, max_t, sd_t). The results corroborated the expected non-linear changes of average IPR indicators in the observed developmental period, whereby the sex difference in related developmental patterns was detected: marked age-related decrement in girls ceased at the age of 12, and in boys around the age of 13-14, after which progress in both sexes gradually ceased by the age of 18 and was less pronounced in girls. Generally similar non-linear age-related decrements of non-average indicators were registered, but they showed mutual intensity differences at specific ages and sex difference in developmental patterns was detected, analogously to average indicators. Systematic sex differences in the whole observed period were obtained only in two non-average indicators: girls showed minor sd_t and boys showed minor min_t. In specific age groups, a number of sex differences were obtained that are explainable by two possible mechanisms: earlier maturation in girls and sex bias of the IPR task content. The justifiability of separate, average and non-average, IPR indicators application was corroborated by their distribution form differences, by mutual, predominantly low and medium correlations, by the different intensity of their developmental changes and by their different ability to detect sex differences. For all registered phenomena, the theoretical and/or empirical explanations were offered from the domain of sex specific intellectual, motor and neural development, and it has been shown that non-average IPR indicators do register age and sex differences, which average indicators do not manage to register.

Recent achievements in preventive dentistry by introducing a new probiotic toothpaste.

Artificially synthesized probiotic from Lactobacillus strain, contained in the tested toothpaste, led to an innovative approach in preventive dentistry. A new concept resulting from this research can be explained due to possible mechanisms of action of probiotic bacteria, according to which equilibrium of hostile bacterial flora is achieved by mechanical elimination of cariogenic bacteria from the mouth. This research was conducted during a 4-week period on a randomly selected Croatian sample of 50 participants, with the aim to investigate the efficacy of the first probiotic toothpaste ever produced in Croatia. CRT tests (Ivoclar Vivadent AG, FL-9494 Schaan/Liechtenstein) were used and individually administrated to each participant to assess the number of Streptococci and Lactobacilli. Saliva samples were tested before, as well as 2 and 4 weeks after using the tested toothpaste. After having had obtained detailed information on the research protocol, participants signed informed consent, and strictly following the instructions, brushed their teeth exclusively using the tested toothpaste and toothbrush of the same manufacturer over the 4 week period. Statistical results obtained after 4 weeks of using the probiotic toothpaste showed significant reduction in the number of participants who, prior to commencing the study, were diagnosed a high number of cariogenic bacteria. The number of participants with the high number of streptococci was significantly reduced from 78.4 to 26.5%, as well as the number of participants with the high number of Lactobacilli, which significantly dropped down from 52.9 to 26.5%. The results indicate a significant efficacy of the tested toothpaste, which can be attributed to the effect of the contained synthetized probiotic substance. Therefore, this research reveals a new achievement in innovative technologies, based on which probiotics can be used with purpose of maintaining balance of bacterial flora within the oral cavity, particularly in high risk groups who are more prone to developing caries.

Oral Health in the Down Syndrome Population: Parental Perceptions on Dental Care in the United States.

Purpose: To assess the oral health status of children with Down syndrome (DS) in the United States and evaluate the oral health needs of families with DS. Methods: Among 320 parents who consented to participate, 260 (81.2 percent) surveys were completed. A survey was distributed through the National Down Syndrome Society to parents of children with DS up to age 21 years, which asked questions about children's general and oral health. Results: Parents who reported that their children had difficulty rinsing and spitting were more likely to report their child's overall general health as poor (P<0.05). Parents' frequency of daily toothbrushing was similar to their children's toothbrushing habits (P<0.05). Conclusions: Dysphagia for children with Down syndrome may negatively impact oral health in addition to general health. Encouraging parental involvement in oral care for children with DS may lower their risk for oral disease. Continued support is needed to ensure dental school education includes training for the treatment and management of patients with DS.

Anthropometrical characteristics of the population of the island of Rab.

The paper presents the results of the population structure research on the inhabitants of the Island of Rab by the analysis of anthropometric, continuous characteristics (morphological variables of head and body) on the representative sample of 601 adult persons (aged 18-75 years) from the settlements Banjol, Barbat, Lopar, Rab and Supetarska Draga (Figure 1). The aim was to investigate the possibility to confirm the existence of population groupings or divisions in one geographically limited area based on the analysis of continuous anthropometric variables. In other words, the purpose is to investigate the structure of the inhabitants in order to contribute to the explanation of its microevolution. The performed analysis shows partial anthropometric variability of the present day population that is confirmed by a series of biostatistics analyses. The analysis includes continuous (quantitative) characteristics, 36 anthropometric body variables and 14 anthropometric head variables. Heterogeneity among the groups of examinees is evaluated for separate phenotypic characteristics in order to obtain the data on the inhabitants' microevolution. The estimation performed on the total of 36 analyzed body variables showed the existence of statistically significant heterogeneities for 13 variables in men and for women in 8. By descriptive statistic procedures and by the estimation of heterogeneity, in space of the head related phenotypic characteristics, heterogeneity was found for 7 characteristics in men and for 5 in women. Discrimination analyses show that certain heterogeneity exists in some investigated continuous characteristics among individual populations. The results of the biological distances evaluation among the populations of the Island of Rab point to the separation of some populations, primarily of the inhabitants of Lopar.

Gender-specific growth patterns of transversal body dimensions in Croatian children and youth (2 to 18 years of age).

In a cross-sectional study of growth, 5,260 healthy children of both sexes from Zagreb (Croatia) aged 2 to 18 years were measured. Six transversal body dimensions were studied: biacromial, transverse chest, antero-posterior chest, biiliocristal, bicondylar humerus and bicondylar femur diamters. A significant increase in body diameters has been observed until the age of 14 to 15 in girls and until the age of 16 in boys, showing that girls have a 1 to 2 years shorter period of growth. Compared to boys of the same age, they achieved larger amounts of final transversal bone size throughout the whole growth period. The most pronounced example was the knee diameter that in girls attained 95% of adult size as early as the age of 10. In both genders, the adult size is achieved earlier in widths of the extremities than in those of the trunk. The studied transversal body segments showed different growth dynamics, which is gender-specific. While sexual dimorphism in pelvic and shoulder diameters emerged with pubertal spurt, gender differences in chest and extremities' diameters started early in life. In all ages, boys had larger chest, elbow and knee diameters. In pubertal age boys gained a significantly larger biacromial diameter (from the age of 13 onwards), while girls exceeded them in biiliocristal diameter (from 10 to 14 years). The findings of gender differences were compared to those reported for other European populations and their growth patters were discussed comparing viewpoints.

Metabolic syndrome in an island population of the eastern Adriatic coast of Croatia.

The metabolic syndrome, an assemblage of risk factors, viz., obesity, dyslipidemia, carbohydrate intolerance, and hypertension, associated with development of cardiovascular diseases and Type 2 diabetes, has become a major public health problem in the developed countries. However, data on its prevalence in worldwide populations, particularly in non-industrialized societies is sparse. We report the prevalence of metabolic syndrome in an island population of the eastern Adriatic coast of Croatia, a distinctly homogenous population living in relative isolation with a traditional way of life style pattern. The participants consist of 381 unrelated individuals (136 males, 245 females) from the island of Hvar, age 19 and above. Hvar is among the most populated Croatian islands with a total population of 11,459 individuals according to the 1991 census. Metabolic syndrome was assessed following the National Cholesterol Education Program (NCEP) criteria, with the exception of using body mass index and waist hip ratio as the predictors of obesity. Overall age-adjusted prevalence of metabolic syndrome is 26% (32% in males and 24% in females) with body mass index, and 42% (57% in males and 36% in females) with waist hip ratio as the measures of obesity. Pairwise correlations of the age and sex-adjusted individual components show that with the exception of fasting plasma glucose, the other components of metabolic syndrome are significantly associated with each other, suggesting their co-morbidity. In spite of adherence to a relatively traditional life-style pattern together with a "Mediterranean diet" and rural habitat, the prevalence of metabolic syndrome is substantially high in the population of Hvar. It is likely that factors other than nutritional practices, that might include genetic susceptibility, could potentially be important in predisposition to metabolic syndrome.

Prevalence of metabolic syndrome in the interior of Croatia: the Baranja region.

Metabolic syndrome (MS), a constellation of metabolic risk factors associated with development of cardiovascular diseases and Type 2 diabetes (T2D), has emerged as a public health problem of enormous proportions in developed and developing countries. We have reported previously its prevalence in several island populations of the Eastern Adriatic coast of Croatia. In spite of leading a relatively traditional life style pattern including adherence to a Mediterranean diet, the prevalence of MS in these populations is high and comparable to that in developed nations. However, data on prevalence of MS among the mainland Croatian populations is limited. Therefore, we conducted a study in an outbred population comprising of Croats, Hungarians and Serbs from the Baranja region of mainland Croatia. Although this is an ethnically heterogeneous population, the constituent groups exchange mates and therefore, are not reproductively isolated. The life style patterns are also similar. Overall prevalence of MS, assessed by the National Cholesterol Education Program (NCEP) criteria, is 40% (35% in males and 42% in females) with Body Mass Index (BMI) as the predictor of obesity and 42% (52% in males and 39% in females) with Waist Hip Ratio (WHR) as the predictor of obesity. It is likely that, in addition to genetic risk factors, a host of environmental factors that include dietary habits and relatively urban life style in a modernized society have influenced the levels of the constituent metabolic traits leading to an increased prevalence of MS.

New anthropometric instruments.

Anthropometric examinations have been carried out since 1901 (USA) with the aim of developing and furthering the garment and footwear size system. The contribution to the solution of these problems was noticed in the last decades when a technical board was founded and the propositions in ISO norm series as well as in European norm (EN) series were prescribed. Two methods are employed in anthropometric measurements: the conventional one using anthropometric instruments and the one applying a 3D body scanner. The method using 3D scanning is faster and more accurate, but at the same time it is more complicated and expensive. In the framework of STIRP Croatian Anthropometric System the classical method was applied because out of the total number of examinees (0.68% of the whole population of the Republic of Croatia) 6,380 children up to the age of 5, 4 were examined. That was the reason why the development of new anthropometric instruments was taken up with the aim of developing and improving the existing ones. In this paper a new anthropometer with two legs has been described: it contributes to the stability of the instrument when a larger number of examinees has to be tested. In addition to this, new goniometers for determining the shoulder-tilt have been presented and described.

Dental anxiety in relation to emotional and behavioral problems in Croatian adolescents.

The investigation was performed on 113 adolescents in the age between 15 and 18 years (63 boys, 50 girls). Corah Dental Anxiety Scale (CDAS) and Children's Fear Survey Schedule - Dental Subscale (CFSS-DS) were used for evaluation of dental fear and Child Medical Fear Questionnaire (CMFQ) for evaluation of the fear of medical treatment. Achenbach Youth Self Report questionnaire (YSR) was used for evaluation of emotional and behavioral problems. The tests were filled in by children. The aim of the study was to evaluate the level of dental anxiety in adolescents and to assess a cause--consequence relationship between dental anxiety and emotional and behavioral problems in adolescents. The results of CDAS, CFSS-DS and CMFQ tests showed that dental anxiety scores and the total internalizing problems were higher in girls. Girls displayed more physical problems (p < 0.001) and were more prone to anxiety/depression disorders (p < 0.05). Both boys and girls were more aggressive, more prone to delinquent behaviour and had more externalizing problems in comparison with the average values obtained for the Croatian population. Significant correlation coefficients for boys were calculated for age and anxiety/depression, and delinquent behaviour and aggression (p < 0.05). Significant correlations were observed between physical problems and dental anxiety measured by the CFSS-DS test (p < 0.01), and between physical problems and the total internalizing problems (p < 0.05). In girls, the CMFQ scores showed significant correlations between dental anxiety and physical problems (p < 0.05), and anxiety/ depression (p < 0.01) and the total internalizing and externalizing problems (p < 0.05). Significant correlations were calculated for age and the total internalizing and externalizing problems for boys (p < 0.05). According to the results of both CDAS and CMFQ tests, anxiety in girls showed significant correlations with delinquent behaviour (p < 0.01). CDAS scores for girls showed significant correlations with aggression (p < 0.05) and the total externalizing problems (p < 0.01).

Dental caries in disabled children.

The aim of the study was to evaluate oral health conditions and dental caries status in disabled and healthy children. Two groups of randomly selected children 3-17 years old were examined. The first group comprised 80 children with disabilities (cerebral palsy, mental retardation, Down syndrome, autism and hearing-speaking disorders) and the second (control) group included 80 healthy children. Examined children were selected from several institutions which take care of disabled persons, kindergardens and four elementary schools. Clinical examination was performed by using a mirror and a probe and revealed the presence of dental caries, missing (extracted) and filled teeth. All clinically detected cavitations were registered as dental caries. The degree of oral hygiene was evaluated according to the OHI-S index values, which was determined by marking the plaque with 1% eozine solution. The values of OHI-S index ranged from 3.8-4.53 in disabled children and 2.73-2.84 in healthy children. In disabled children, the average dft values were 3.42 in deciduous teeth and 5.24 in mixed dentition. In healthy children, the average dft values were 1.43 in deciduous teeth and 5.1 in mixed dentition. The average DMFT index in disabled children was 1.41 for mixed and 6.39 for permanent dentitions. In healthy children, the average DMFT values were 1.23 in mixed and 4.76 in permanent dentitions. In general, the results revealed significantly poor level of oral hygiene and quite high level of caries prevalence in both disabled and healthy children, accentuating the need to reorganize preventive care measurements and improve dental care, particularly in disabled children in Croatia.

Antiproliferative, antiangiogenic and apoptotic effect of photochemotherapy (PUVA) in psoriasis patients.

The aim of the study was to investigate the antiproliferative, antiangiogenic and apoptotic effect of photochemotherapy (PUVA) in psoriatic patients, and to compare it with a control group of psoriatics treated with local corticosteroid therapy. The study included 60 psoriasis patients, 30 of them allocated to PUVA therapy and local corticosteroid each. Immunohistochemical methods of staining with Ki-67, F-8 and bcl-2 antibodies were used to determine proliferative keratinocyte count, to visualize the number of blood vessels in the dermis, and to determine the number of cells exhibiting expression of the antiapoptotic oncoprotein bcl-2, respectively. In all study patients, the values of Ki-67, F-8, bcl-2 and PUVA score were recorded pre- and at six weeks post-therapeutically. Study results showed a statistically significant decrease in the epidermal proliferative keratinocyte count and dermal number of blood vessels after both therapeutic modalities (p < 0.001 both). The value of bcl-2 showed a statistically significant increase in the group of patients treated with PUVA therapy (p = 0.001) and an increase in the control group, demonstrating enhanced keratinocyte apoptosis after treatment. Accordingly, study results demonstrated the antiproliferative, antiangiogenic and apoptotic effect of both PUVA and local corticosteroids. These very mechanisms appear to play a key role in the action of most antipsoriatic therapies.

Anthropometry and the comparison of garment size systems in some European countries.

This work points to the relevance of regional and state systems of garment sizes. High quality, garment size systems, garment design and economy are currently the focal points, which belie the outdated strategy of competitiveness based on product cost. The average body dimensions have considerably changed in the last decades. We have investigated these differences in a number of European countries and compared the garment size systems. A concrete example is provided by the hind part of women's trousers and comparisons have been made. The conclusion is that most countries still possess their own official garment size systems, which differ in many aspects from the others. In addition, larger firms in some countries use their internal standards, which vary to some extent. The conclusion based on research is that they depend on the function and purpose of the garment, on trends in fashion, on the design and on the economy of production.

Causal Bayesian network for tagging syntactical structure of Croatian sentences.

Paper describes tagging syntactical structure of Croatian language sentences using causal Bayesian network. In the first part of the paper we describe Bayesian model for tagging sentences. Base on this idea, we will test our model on Croatian language sentences on Database of grammatical sentences of Croatian language (http://infoz.ffzg.hr / tepes /). This paper is result of our new research connected with the paper hidden Markov model for tagging of Croatian language texts for project Linguistic Analysis of The European languages and the paper Probability distribution on the parse trees for the project Annotated database and syntactic structure of Croatian languages.

Morphological status of cadets and pilots of the Croatian Air Force.

Results of the analysis of morphological status of cadets and pilots of the Croatian Air Force are presented, in relation to the morphological status of a sample of conscripts of the Croatian Army. The results of the morphological status of body built of the flier potential of the Croatian Air Force, i.e., the potential (cadets) and active fliers (pilots), suggest a process of spontaneous (or possibly systematic) selection of flier candidates based on anthropometric criteria. Based on the obtained anthropometric data, it may be concluded that persons who choose to candidate for and are selected to join the Croatian Air Force as pilots, are of specific personal appearance and body built.

The Child Behavior Checklist, Teacher Report Form and Youth Self Report problem scales in a normative sample of Croatian children and adolescents aged 7-18.

The main goal of this study was to standardize the Child Behavior Checklist (CBCL), Teacher Report Form (TRF) and Youth Self Report (YSR) questionnaire problem scales on a normative random sample of children and adolescents (N=3309) aged 7 to 18 throughout Croatia. The second goal was to compare boys-girls problem scales data and CBCL-TRF-YSR differences in our sample. The mean value of CBCL scores for the Total Problems scale for different groups (children/adolescents; boys/girls) ranged from 17.07 to 20.71. Overall instruments' internal consistency ranged from 0.83 to 0.86. In almost all the scales parents reported higher scores than teachers (p < 0.01). In all the scales adolescents reported significantly higher scores than their parents and teachers (p < 0.01). This study standardized the questionnaires for our specific socio-cultural circle, which satisfy complex psychopathology study criteria. Problem scales results in our sample suggest similarity to previous European researches.

Comparison of self-reported and parent-reported emotional and behavioral problems in adolescents from Croatia.

The first goal of this study was to obtain, Child Behavior Checklist (CBCL) and Youth Self-Report (YSR) problem-scales data for youths in Croatia, and compare them to the original American sample. The second goal of this study was to compare boys -girls problem scales data and CBCL-YSR differences. The instruments were administered to school adolescents aged between 12-18 comprising a non-referred sample (n=611) drawn from the whole country. Youths, compared to their parents, rated higher scores in all scales in both sexes (p < 0.001). According to parents' reports boys had higher scores in more scales (five out of eleven). According to adolescents'self-reports girls had higher scores in more scales (seven out of eleven). Consistent with other studies, Croatian sample confirmed a larger number of serious behavioral and emotional problems reported by adolescents. Adolescents were confirmed as the most reliable informants on their problems.

The structure of body measurements for the determination of shoe sizing for young Croatian men.

The determination and promotion of the system of shoe sizing requires accurate knowledge of morphological properties of the foot and lower leg of the tested population. Similarly it is necessary to establish the occurrence and regional distribution of definite sizes in the tested population. Possible regional differences in morphological properties must not be ignored because it has been established by means of anthropological measuring that both foot dimensions and foot shapes differ between populations and within the same population. This has been proven by the investigation of body measures, carried out for the purpose of establishing a system of footwear sizes, which was executed on a randomly selected sample of 4,268 healthy and normally developed males aged 18-22. The investigation was carried out in 1993 on five locations each of which representing a definite region of the Republic of Croatia: Jastrebarsko (central), Koprivnica (northwestern), Pula (southwestern), Sinj (southern) and Pozega (northeastern). The measuring instrument was 31 foot and lower-leg sizes according to the existing ISO standards for footwear. Interregional differences are significant in all body measures. The role and the contribution of individual measures to these differences has been established by means of discriminatory analysis with regions as a priori defined samples. In order to constitute a convenient and purposeful standard for the footwear size system it is necessary to work out a database with referent values for the same system.

Gender-specific growth patterns for stature, sitting height and limbs length in Croatian children and youth (3 to 18 years of age).

In a cross-sectional study of growth, 5,155 children (2,591 females, 2,564 males) from the town of Zagreb (Croatia) were measured. Four traits of linear dimensionality (stature, sitting height, arm and leg lengths) were studied in the age span of 3 to 18 years. A significant average annual increase of all four anthropometric parameters were observed up to 14 and 15 years of age in girls and 16 years of age in boys, showing that girls had a shorter growing period. In the prepubertal period until 9 years of age, gender differences were negligible. At the age of 10, boys were overgrown by girls in all parameters due to the earlier onset of puberty in girls. The growth gains for girls, when compared with those for boys, show a different pattern across variables. The female growth advantage remained in a two years period for the limbs length, but in a three year period for stature and the longest, for 4 years, for sitting height. The male predominance in size had an onset at the age of 13 for the limbs and in the age of 14 for stature and sitting height. The patterns of sexual dimorphism in stature and sitting height during growing years are similar to those observed in other populations of Europe. Growth of Croatian children and youth is very similar to that of the tallest European populations.

Lost in transition--the Island of Susak (1951-2001).

The isolated population of the Island of Susak was thoroughly studied by a multidisciplinary team of the Croatian Academy of Sciences and Arts in early 1950's. Recently, a team of scientists revisited the island. This paper describes the main characteristics of the transition process during which a massive exodus occurred with 90% of the island's population migrating to New Jersey, USA. We summarise the differences in lifestyle, economy, social structure and sense of identity between the historic (1950's) and contemporary (2001) Susak population. We applied contemporary methods (analysis of microsatellite DNA polymorphisms) to investigate local myths about extreme levels of inbreeding and genetic homogeneity among the Susak islanders. Analysis of short-tandem-repeat (STR) loci showed that Susak displayed characteristics of a small homogeneous breeding isolate. The average heterozygosity was found to be low compared to outbred populations. The signature of a recent severe bottleneck could be detected. Analysis of 8 markers located on Xq13-21 in 71 individuals suggested extensive level of linkage disequilibrium (LD). A migrant study was designed to investigate the effects of large environmental changes (Susak vs. USA) and inbreeding (Susak vs. Croatian general population) on some biologically important quantitative traits, such as blood pressure and serum lipids. The results confirmed the positive correlation between inbreeding level and blood pressure that has been reported in the literature on several occasions. The last remnants of this traditional island community will soon be lost forever.
