Overweight and school performance among primary school children: the PIAMA birth cohort study

The aim of this study was to assess the association between overweight and school performance among primary school children prospectively and including a broad range of potential confounding factors. In addition it was investigated what factors mediate this association. For this purpose, data of 2,159 12-year-old children who participated in the Prevention and Incidence of Asthma and Mite Allergy (PIAMA) birth cohort study were used. Two indicators of school performance were parental reported when children were 12 years of age and included (i): the score on a standardized achievement test that Dutch children have to complete at the end of their primary education (Cito)-test and (ii): the teacher's advice regarding a child's potential performance level in secondary education. Children's height and weight were measured by a trained research assistant at the age of 8 and by their parents at the age of 12. Overweight was defined using age and gender specific cut-off points. Multivariate regression analyses were performed to assess the association between overweight and school performance. Besides, both confounder and mediation analyses were conducted. Results showed lower Cito-test scores and lower teacher's school-level advice among overweight children. These associations were no longer significant when adjusting for parental educational level, skipping breakfast, and screen time. This study found no independent association between overweight and school performance among primary school children. Results showed strong confounding by parental educational level.     

Performance of Dutch Children on the Bayley III: A Comparison Study of US and Dutch Norms

Background

The Bayley Scales of Infant and Toddler Development-third edition (Bayley-III) are frequently used to assess early child development worldwide. However, the original standardization only included US children, and it is still unclear whether or not these norms are adequate for use in other populations. Recently, norms for the Dutch version of the Bayley-III (The Bayley-III-NL) were made. Scores based on Dutch and US norms were compared to study the need for population-specific norms.

Methods

Scaled scores based on Dutch and US norms were compared for 1912 children between 14 days and 42 months 14 days. Next, the proportions of children scoring < 1-SD and < -2 SD based on the two norms were compared, to identify over- or under-referral for developmental delay resulting from non-population-based norms.

Results

Scaled scores based on Dutch norms fluctuated around values based on US norms on all subtests. The extent of the deviations differed across ages and subtests. Differences in means were significant across all five subtests (p < .01) with small to large effect sizes (η _p ²) ranging from .03 to .26). Using the US instead of Dutch norms resulted in over-referral regarding gross motor skills, and under-referral regarding cognitive, receptive communication, expressive communication, and fine motor skills.

Conclusions

The Dutch norms differ from the US norms for all subtests and these differences are clinically relevant. Population specific norms are needed to identify children with low scores for referral and intervention, and to facilitate international comparisons of population data.

Predictive testing for Huntington disease: nonparticipants compared with participants in the Dutch program.

Attitudes toward predictive testing programs, in individuals who choose not to undertake the test (i.e., nonparticipants), may be influenced by fears of an unfavorable result. The reasons not to participate in predictive testing programs for Huntington disease (HD) were studied in members of the Dutch Huntington Association who were at 50% risk. They had completed the same baseline psychological questionnaires as had the participants in the Dutch DNA-testing program. The group of 34 nonparticipants was similar to the tested participants in the Dutch predictive testing program, with respect to average age (31.1 years), male:female ratio (1:2), the frequency of a stable relationship (70%), and level of education (67% had high school education or higher). Testing did not seem to be a realistic option for nonparticipants for improving their quality of life. In comparison with participants, nonparticipants had a significantly more pessimistic outlook on themselves and their futures. When asked to consider the possibility of an unfavorable result, nonparticipants expected more difficulties in their families; more problems for their children, their partners, and themselves; a lowered quality of life; and, more often, a depressive reaction. In their opinion, a favorable result would reduce the problems for their children but not for themselves, a result that was found more often in the nonparticipant than in the participant group. Nonparticipants learned about their being at risk for HD during adolescence (mean age 15.6 years), whereas participants did so in adulthood (mean age 22.7 years). The nonparticipants' attitude toward the test might be explained by the influence of HD in the adolescent's separation-individuation process and personality development. This finding could be relevant for future research and for the discussion about testing minors for delayed-onset disorders.

The Gender Gap in Second Language Acquisition: Gender Differences in the Acquisition of Dutch among Immigrants from 88 Countries with 49 Mother Tongues

Gender differences were analyzed across countries of origin and continents, and across mother tongues and language families, using a large-scale database, containing information on 27,119 adult learners of Dutch as a second language. Female learners consistently outperformed male learners in speaking and writing proficiency in Dutch as a second language. This gender gap remained remarkably robust and constant when other learner characteristics were taken into account, such as education, age of arrival, length of residence and hours studying Dutch. For reading and listening skills in Dutch, no gender gap was found. In addition, we found a general gender by education effect for all four language skills in Dutch for speaking, writing, reading, and listening. Female language learners turned out to profit more from higher educational training than male learners do in adult second language acquisition. These findings do not seem to match nurture-oriented explanatory frameworks based for instance on a human capital approach or gender-specific acculturation processes. Rather, they seem to corroborate a nature-based, gene-environment correlational framework in which language proficiency being a genetically-influenced ability interacting with environmental factors such as motivation, orientation, education, and learner strategies that still mediate between endowment and acquiring language proficiency at an adult stage.     

Trend in Height of Turkish and Moroccan Children Living in The Netherlands

ObjectivesTo study trends in height of Turkish and Moroccan immigrant children living in The Netherlands, to investigate the association between height and background characteristics in these children, and to calculate height-for-age-references data for these groups.DesignNationwide cross-sectional data collection from children aged 0 to 18 years by trained professionals in 1997 and 2009. The study population consisted of 2,822 Turkish 2,779 Moroccan, and 13,705 Dutch origin children in 1997and 2,548 Turkish, 2,594 Moroccan, and 11,255 Dutch origin children in 2009. Main outcome measures: Mean height in cm, and mean height standard deviation scores.ResultsIn 2009, mean height at the age of 18y was similar for Turkish and Moroccan children: 177 cm for boys and 163 cm for girls, which was 2 to 3 cm taller than in 1997. Still, Turkish and Moroccan adolescents were 5.5 cm (boys) to 7 cm (girls) shorter than their Dutch peers. No significant differences were found in mean height standard deviation scores across the educational level of the parents, geographical region, primary language spoken at home, and immigrant generation.ConclusionsWhile the secular height increase in Dutch children came to a halt, the trend in Turkish and Moroccan children living in The Netherlands continued. However, large differences in height between Turkish and Moroccan children and Dutch children remain. We found no association with the background characteristics. We recommend the use of the new growth charts for children of Turkish and Moroccan origin who have a height-for-age below -2SD on the growth chart for Dutch children.     

A framework for actualising normalisation data in LCA: Experiences in the Netherlands

In LCA, normalisation is applied to quantify the relative size of the impact scores. Several sets of normalisation data exist in the Netherlands, which all have a certain degree of unreliability. The purpose of this study is to actualise Dutch normalisation data and to make a framework for deriving these data. In this study normalisation data are calculated for three different levels in order to give the LCA practitioner a more extended basis for preparing the interpretation process. The first level of normalisation contains all impacts relating to activities that take place within the Dutch territory. The second level is based on the Dutch final consumption, which means that import and export are taken into account. The third level is an attempt to estimate impacts in Europe based on European data if possible, and otherwise based on extrapolation from the Dutch situation.     

Why Japanese workers show low work engagement: An item response theory analysis of the Utrecht Work Engagement scale

With the globalization of occupational health psychology, more and more researchers are interested in applying employee well-being like work engagement (i.e., a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption) to diverse populations. Accurate measurement contributes to our further understanding and to the generalizability of the concept of work engagement across different cultures. The present study investigated the measurement accuracy of the Japanese and the original Dutch versions of the Utrecht Work Engagement Scale (9-item version, UWES-9) and the comparability of this scale between both countries. Item Response Theory (IRT) was applied to the data from Japan (N = 2,339) and the Netherlands (N = 13,406). Reliability of the scale was evaluated at various levels of the latent trait (i.e., work engagement) based the test information function (TIF) and the standard error of measurement (SEM). The Japanese version had difficulty in differentiating respondents with extremely low work engagement, whereas the original Dutch version had difficulty in differentiating respondents with high work engagement. The measurement accuracy of both versions was not similar. Suppression of positive affect among Japanese people and self-enhancement (the general sensitivity to positive self-relevant information) among Dutch people may have caused decreased measurement accuracy. Hence, we should be cautious when interpreting low engagement scores among Japanese as well as high engagement scores among western employees.     

Grey Matter Correlates of Three Language Tests in Non-demented Older Adults

Language has been extensively investigated by functional neuroimaging studies. However, only a limited number of structural neuroimaging studies have examined the relationship between language performance and brain structure in healthy adults, and the number is even less in older adults. The present study sought to investigate correlations between grey matter volumes and three standardized language tests in late life. The participants were 344 non-demented, community-dwelling adults aged 70-90 years, who were drawn from the population-based Sydney Memory and Ageing Study. The three language tests included the Controlled Oral Word Association Task (COWAT), Category Fluency (CF), and Boston Naming Test (BNT). Correlation analyses between voxel-wise GM volumes and language tests showed distinctive GM correlation patterns for each language test. The GM correlates were located in the right frontal and left temporal lobes for COWAT, in the left frontal and temporal lobes for CF, and in bilateral temporal lobes for BNT. Our findings largely corresponded to the neural substrates of language tasks revealed in fMRI studies, and we also observed a less hemispheric asymmetry in the GM correlates of the language tests. Furthermore, we divided the participants into two age groups (70-79 and 80-90 years old), and then examined the correlations between structural laterality indices and language performance for each group. A trend toward significant difference in the correlations was found between the two age groups, with stronger correlations in the group of 70-79 years old than those in the group of 80-90 years old. This difference might suggest a further decline of language lateralization in different stages of late life.     

Effects of growth hormone treatment on cognitive function and head circumference in children born small for gestational age

Short stature is not the only problem faced by children born small for gestational age (SGA). Being born SGA has also been associated with lowered intelligence, poor academic performance, low social competence and behavioural problems. This paper summarizes the results of a randomized, double-blind, growth hormone (GH) dose-response study (1 or 2 mg/m2/day [ approximately 0.035 or 0.07 mg/kg/day]) on growth, intelligence quotient (IQ) and psychosocial functioning in 79 children born SGA at the start, and after 2 and 8 years of GH therapy, and addresses the associations with head circumference. Mean age at start of therapy was 7.4 years; mean duration of GH treatment was 8.0 years. In 2001, 91% of children born SGA had reached a normal height (> -2.0 standard deviation score [SDS]). Block-design s-score (Performal IQ) and Total IQ score increased (p < 0.001 for both indices) from scores significantly lower than those of Dutch peers at the start of therapy (p < 0.001) to scores that were comparable to those of Dutch peers in 2001. Vocabulary s-score (Verbal IQ) was normal at the start of therapy and remained so over time. Externalizing Problem Behaviour SDS and Total Problem Behaviour SDS improved during GH therapy (p < 0.01-0.05) to scores comparable to those of Dutch peers. Internalizing Problem Behaviour SDS was comparable to that of Dutch peers at the start of therapy and remained so, whereas Self-Perception improved from the start of GH therapy until 2001 (p < 0.001), when it reached normal scores. Head circumference SDS at the start of GH therapy and head growth during GH therapy were positively related to all IQ scores (p < 0.01), whereas neither were related to height SDS at the start of, or to its improvement during, GH therapy. A significant improvement in height and head circumference in children born SGA was seen after only 3 years of GH therapy, in contrast to randomized SGA controls. In conclusion, most children born SGA showed a normalization of height during GH therapy and, in parallel to this, a significant improvement in Performal IQ and Total IQ. In addition, problem behaviour and self-perception improved significantly. Interestingly, Performal, Verbal and Total IQ scores were positively related to head circumference, both at the start of, and during, GH therapy; head circumference increased in GH-treated children born SGA, but not in untreated SGA controls. These results are encouraging but also warrant confirmational studies and further investigations into the effects of GH on the central nervous system.     

Telefonisch Interview Cognitieve Status (TICS): psychometrische aspecten

The psychometric properties of the Dutch version of the Telephone Interview Cognitive Status (TICS). The Telephone Interview Cognitive Status (TICS) is an instrument to screen for dementia in older persons by telephone. Although the psychometric properties of the TICS have been studied in various countries, the quality of the Dutch version of the TICS was yet unknown. This paper presents the Dutch version of the TICS and reports on its reliability and validity among 51 patients of Maastricht University Hospital, the Netherlands. The Pearson and intra-class correlations for test-retest reliability were 0,93 and 0,92, respectively. The Pearson and intra-class correlations for inter-rater reliability were 0,91 and 0,90, respectively. Sensitivity and specificity were studied in relation to the Mini Mental State Examination (MMSE, cut-off point 23/24) and the diagnosis of dementia as assessed according to DSM-IV criteria. When using the TICS cut-off point of 26/27, the coefficients for sensitivity and specificity were at least 0,80. The percentages ROC under the curve were 90% and 93% with the MMSE and the diagnosis dementia as criterion, respectively. We conclude that the Dutch version of the TICS is an acceptable instrument for screening for dementia in older persons, particularly when face-to-face contact is not possible.     

Validity and Reliability of the Dutch Adaptation of the Psoriatic Arthritis Quality of Life (PsAQoL) Questionnaire

Objective

The Psoriatic Arthritis Quality of Life (PsAQoL) questionnaire is a disease- specific instrument developed to measure quality of life (QoL) in patients with psoriatic arthritis (PsA). The aim of this study was to translate the measure into Dutch and to determine its psychometric properties.

Method

Translation of the original English PsAQoL into Dutch was performed by bilingual and lay panel. Ten field-test interviews with PsA patients were performed to assess face and content validity. In total, 211 PsA patients were included in a test-retest postal survey to investigate the reliability and construct validity of the Dutch adaptation of the PsAQoL. The PsAQoL, Health Assessment Questionnaire (HAQ) and Skindex-17 were administered on two different occasions approximately two weeks apart.

Results

The Dutch version of the PsAQoL was found to be relevant, understandable and easy to complete in only a few minutes. It correlated as expected with the HAQ (Spearman’s ρ = 0.72) and the 2 subscales of the Skindex-17 (ρ = 0.40 for the psychosocial and ρ = 0.46 for the symptom scale). Furthermore, the measure had good internal consistency (Cronbach’s α = 0.92) and test-retest reliability (ρ = 0.89). The PsAQoL was able to define groups of patients based on self-reported general health status, self-reported severity of PsA and flare of arthritis. Duration of PsA did not influence PsAQoL scores.

Conclusions

The Dutch version of the PsAQoL is a valid and reliable questionnaire suitable for use in clinical or research settings to asses PsA-specific QoL.     

Neuroticism in the elderly. The utility of the shortened DPQ-scales

This article reports on the relation between aging and personal adjustment. Current personality scales are not developed for older persons. Scales contain items which are not valid for an aging population and contain too many items for administration in older populations. As part of the Longitudinal Aging Study Amsterdam (LASA) Neuroticism in older persons was measured with a shortened version of the Inadequacy (IN) and Social Inadequacy (SI) scales of the Dutch Personality Questionnaire (DPQ). The utility of these shortened scales was assessed based on internal consistency, inter-item correlations, test-retest reliability and factor analysis. The consistency of the personality dimension Neuroticism was assessed based on cohort-differences and a 6-year longitudinal comparison. The research-population contained 2118 respondents at baseline, aged between 55 and 85 years, 49% were male and they were not living in an institution. The shortened scales appeared to be reliable and valid instruments to measure Neuroticism in the elderly. The gaining of time due to the administration of the shortened scales enlarges the feasibility of the scales for measuring Neuroticism in older persons. Results showed no significant age-difference on the IN-scale, but revealed a significant difference on the SI-scale (p < .01). The 65+ elderly (65-74 and 75-85) have higher scores on Social Inadequacy than the youngest elderly (55-64). Longitudinal analyses showed an interaction between age at baseline and the stability and change of the level of Neuroticism. On both scales the youngest age-group showed a significant decline in mean level of Neuroticism (p < .01). The mean level of Social Inadequacy in the oldest age-group showed an increase during the 6-year follow-up period (p < .05). However, the differences were very small. Future research is needed to assess the effect of related variables on Neuroticism in older persons.     

Public attitudes toward genetic testing: perceived benefits and objections

The aim of this study was to assess public attitudes toward the availability and use of genetic tests to explore support for genomics developments and to help improve public discussion. Questionnaires to assess the assumed advantages and disadvantages of genetic testing were sent to a representative sample of the Dutch population (n = 1,308; age > or =25 years). The response was 63% (817/1,308). Two groups with extreme scores on a four-item scale were distinguished, representing opponents (n = 248) and supporters (n = 264) of the availability and use of genetic tests. Multiple logistic regression analyses showed that those who were familiar with a genetic disease (odds ratio [OR] 0.54; 95% confidence interval [CI] 0.32-0.89; p = 0.015), those who scored higher on a four-item scale on belief in personal benefits of testing (OR 0.29; 95% CI 0.21-0.40; p < 0.0001), and those who believe that knowledge of the genetic background of disease will help people to live more healthy lives (OR 0.48; 95% CI 0.37-0.62; p < 0.0001), were less likely to be opponents. Those who agreed that genetic testing is tampering with nature (OR 1.63; 95% CI 1.32-2.00; p < 0.0001) were more likely to be opponents. Other variables such as belief in genetic determinism, genetic knowledge, level of education, age, and gender were not significantly associated. These results suggest that in addition to moral acceptability, perceived usefulness is a precondition for supporting genetic testing. It is not expected that more information will necessarily result in more positive attitudes.     

The Modified painDETECT Questionnaire for Patients with Hip or Knee Osteoarthritis: Translation into Dutch,Cross-Cultural Adaptation and Reliability Assessment

There is a growing amount of evidence that alteration in pain processing by the peripheral and central nervous system play a role in osteoarthritis pain, leading to neuropathic-like symptoms. It is essential to identify knee and hip osteoarthritis patients with a neuropathic pain profile in order to offer such patients education and additional treatment options besides conventional pain treatment. The painDETECT Questionnaire is a self-report questionnaire developed to discriminate between nociceptive and neuropathic pain. This questionnaire was modified to fit patients suffering from knee osteoarthritis. The aim of this study was to translate and cross-culturally adapt the modified painDETECT Questionnaire to the Dutch language and to provide a modified version to fit patients with hip osteoarthritis. Reliability for internal consistency, repeatability and floor and ceiling effects were subsequently assessed. A total of 278 patients were included in the reliability study and 123 patients in the repeatability analysis. The Dutch modified painDETECT Questionnaire shows good internal consistency and small relative measurement errors, represented by a good intraclass correlation coefficient. Absolute measurement error, represented by the Standard Error of Measurement, was acceptable. However, a measurement bias might be present when it comes to repeatability. To our knowledge, this study is the first to provide a Dutch modified painDETECT Questionnaire to fit hip and knee osteoarthritis patients and to assess internal consistency, reliability and agreement. International guidelines were followed in the translation process and this study has ample sample size with an adequate time interval for repeatability. Based on this study, the Dutch modified painDETECT Questionnaire seems to be fit as a discriminative tool to identify knee and hip osteoarthritis patients with a neuropathic pain profile. Whether it is also suitable as an evaluative tool to record changes over time or after an intervention remains open to further investigation.

Dutch translation and cross-cultural adaptation of the PROMIS? physical function item bank and cognitive pre-test in Dutch arthritis patients

Introduction

Patient-reported physical function is an established outcome domain in clinical studies in rheumatology. To overcome the limitations of the current generation of questionnaires, the Patient-Reported Outcomes Measurement Information System (PROMIS^®) project in the USA has developed calibrated item banks for measuring several domains of health status in people with a wide range of chronic diseases. The aim of this study was to translate and cross-culturally adapt the PROMIS physical function item bank to the Dutch language and to pretest it in a sample of patients with arthritis.

Methods

The items of the PROMIS physical function item bank were translated using rigorous forward-backward protocols and the translated version was subsequently cognitively pretested in a sample of Dutch patients with rheumatoid arthritis.

Results

Few issues were encountered in the forward-backward translation. Only 5 of the 124 items to be translated had to be rewritten because of culturally inappropriate content. Subsequent pretesting showed that overall, questions of the Dutch version were understood as they were intended, while only one item required rewriting.

Conclusions

Results suggest that the translated version of the PROMIS physical function item bank is semantically and conceptually equivalent to the original. Future work will be directed at creating a Dutch-Flemish final version of the item bank to be used in research with Dutch speaking populations.     

Social-economic inequality in mortality among older mem amd women. Research on the role of health, life style, parental socio-economic status and psychosocial conditions

This article describes to what degree socio-economic differences exist among community living older men and women, and to what degree these differences are to be explained by health, behaviour, childhood and psychosocial conditions. The data are available from 1427 men and 1503 women (aged 55-85), participating in the Longitudinal Aging Study Amsterdam (LASA) in 1992/1993. As indicators of socio-economic status (ses) we used the highest level of education and net monthly income. Age-adjusted mortality risks for men and women with low income and for men with a low level of education are about 1.5 times as high as for to the persons with high income and educational level. Among men, but not among women, the difference in mortality risk between low and high status persons remains after adjustment for age, health status, and several risk factors. Differences in lifestyle, parental ses and psychosocial characteristics explain little to nothing of the age-adjusted ses-differentiation in mortality. It is concluded that ses-inequalities in mortality are present among Dutch men and, to a lesser extent among women, until high age, and are partly explained by the relatively large health problems of the lower status group.     

Ethnic differences in lifestyle and overweight in the Netherlands

Objective: To study the effects of lifestyle variables and socioeconomic status on overweight among native Dutch and immigrants in The Netherlands. Research Methods and Procedures: Data were used from a survey sample (N = 2551) of native Dutch and immigrant respondents (Surinamese/Antilleans, Turks, and Moroccans). BMI was calculated using self‐reported weight and height. Lifestyle variables such as modern food habits (take‐out food and eating out) and participating in sports were included, as well as socioeconomic and demographic background variables. Bivariate and ordinary least squares analyses were performed to study BMI and the determinants of overweight among the different groups. Results: All immigrant groups had a higher prevalence of overweight than the Dutch, except Moroccans. Men were overweight more frequently than women. Take‐out food, eating out, and fresh vegetables were related to a decrease in BMI, whereas convenience foods were related to an increase in BMI. For ready‐to‐eat meals, the results were mixed. In all groups, age was associated with a higher BMI, and a higher level of education was associated with a lower BMI. Immigrants participated in sports less frequently than native Dutch people. Discussion: One percent to 5% of the total public health costs can be attributed to costs for overweight‐related diseases. Public health policies should aim at stimulating healthy lifestyles and discouraging bad food habits through higher taxes on high‐calorie foods. In particular, Dutch immigrants should be encouraged to lose weight, because they have a higher risk for overweight‐related diseases.
