Changes over time of fruit, vegetable and sweets consumption among European adolescents and associations with sociodemographic characteristics: an HBSC study

BACKGROUND

European adolescents do not eat enough fruits and vegetables and have a high sweets consumption. This study aims to analyse the changes in time of dietary behaviours related to sociodemographic characteristics, among European adolescents.

METHODS

Health Behaviour in School Age Children data (2013/14 to 2017/18), of European adolescents, aged 11- to15-year-old, were used. Family Affluence Scale identified socioeconomic status (SES). Changes in time of dietary behaviours and associations with sociodemographic characteristics were estimated by binary and multilevel logistic regression.

RESULTS

182 719 adolescents were included, and 10/36 European countries showed a significant increase in daily fruit and vegetable consumption and 12/36 countries a significant decrease in sweets consumption over 4 years. The multilevel analysis showed that 13- and 15-year-old adolescents consumed fewer daily fruits and vegetables (P < 0.001) and more daily sweets (P < 0.001) than 11-year-old adolescents. Also, 15-year-old adolescents' sweets consumption change over time was less favourable (P = 0.006). Girls consumed more daily fruits, vegetables and sweets than boys (P < 0.001).Low SES adolescents consumed fewer daily fruits and vegetables than medium/high SES adolescents. Additionally, the low SES adolescents' vegetable consumption change over time was less favourable (P < 0.001).

CONCLUSIONS

Dietary behaviour policy recommendations should be adapted for the sex, age and SES of the population.

Evaluation of practice nurses' management of paediatric psychosocial problems in general practice

BACKGROUND

Child mental health services are under major pressure worldwide. In the Netherlands, Youth Mental Health Practice Nurses (YMHPNs) have been introduced in general practice to improve access to care. In this study, we evaluated care delivered by YMHPNs.

METHODS

We used medical records of a population-based cohort (21 717 children, 0-17 years). Characteristics of children consulting a YMHPN, type of problem, care delivered by YMHPNs and referrals were assessed using quantitative content analysis.

RESULTS

Records of 375 children (mean age 12.9 years, 59.2% girl) were analysed. These children were often in their adolescence (57.3% was between 13 and 17 years), and more often female than male (59.2% vs 40.8%). YMHPNs had a median of four consultations (IQR 2-7) with the child. YMHPNs managed a variety of psychosocial problems. YMHPNs managed 22.4% of children without need of referral, 52.0% were eventually referred for additional care. 13.3% of children dropped out during the treatment trajectory. In the remaining 12.3% of children, the treatment trajectory was stopped because the child was already attending specialized services, the treatment trajectory was still ongoing or the medical record was inconclusive.

CONCLUSIONS

YMHPNs successfully managed one in four children with psychosocial problems without need for referral. Nevertheless, most children were eventually referred for additional care.

The association between perceived social support and parenting self-efficacy among parents of children aged 0-8 years

Strengthening social support has been recognized as a potentially effective strategy to enhance parenting self-efficacy, but empirical evidence is limited. This study examined the association between perceived social support and parenting self-efficacy.Data of 647 parents of children aged 0-8 years, gathered in the CIKEO cohort study in the Netherlands, were analysed. Data were collected between October 2017 and December 2019. Multivariable linear regression models were used to examine the association between social support and parenting self-efficacy. The mean age of the participants was 33.8 years (SD = 4.9); 94.9% mothers. At the start of the study, 15.1% parents perceived low to moderate social support. Parents who experienced lower levels of social support at the start of the study reported lower parenting self-efficacy at follow-up (β: 0.13; 95% CI: 0.05, 0.21), independent of potential socio-demographic confounders. Experiencing an increase in perceived social support during the study period was associated with an increase in parenting self-efficacy (β: 0.15; 95% CI: 0.10, 0.21). Our findings indicate perceived social support is associated with parenting self-efficacy among parents of children aged 0-8 years. Future longitudinal studies need to confirm our findings and may examine which social support interventions are effective in strengthening parenting self-efficacy.

Citizen Science to improve healthy and active living among adolescents in four European countries: a protocol of the cluster randomised controlled trial of the Science Engagement to Empower aDolescentS (SEEDS) project

INTRODUCTION

Improving healthy lifestyles of adolescents is challenging. Citizen Science is a way to engage them in the design and delivery of interventions, and may also increase their interest in science, technology, engineering and mathematics (STEM). The Science Engagement to Empower aDolescentS (SEEDS) project aims to use an equity-lens, and engage and empower boys and girls from deprived areas by designing and cocreating interventions to promote healthy lifestyles, and to seed interest in STEM.

METHODS AND ANALYSIS

SEEDS is a cluster randomised controlled trial in four countries (Greece, the Netherlands, Spain and the UK). Each country will recruit six to eight high schools from lower socioeconomic neighbourhoods. Adolescents aged 13-15 years are the target population. High schools will be randomised into intervention or control group. Each country will select 15 adolescents from intervention schools called ambassadors, who will be involved throughout the project.In each country, focus groups with ambassadors and stakeholders will focus on physical activity, snacking behaviour and STEM. The input from focus groups will be used to shape Makeathon events, cocreation events where adolescents and stakeholders will develop the interventions. The resultant intervention will be implemented in the intervention schools during 6 months. In total, we aim to recruit 720 adolescents who will complete questionnaires related to healthy lifestyles and STEM outcomes at baseline (November 2021) and after the 6 months (June 2022).

ETHICS AND DISSEMINATION

The four countries obtained approval from their corresponding Ethics Committees (Greece: Bioethics Committee of Harokopio University; the Netherlands: The Medical Research Ethics Committee of the Erasmus Medical Center; Spain: The Drug Research Ethics Committee of the Pere Virgili Health Research Institute; UK: Sport and Health Sciences Ethics Committee of the University of Exeter). Informed consent will be collected from adolescents and their parents in line with General Data Protection Regulation legislation. The findings will be disseminated by conference presentations, publications in scientific peer-reviewed journals and during (local) stakeholders and public events. Lessons learnt and the main results will also be used to provide policy recommendations.

The long-term effects of primary school-based obesity prevention interventions in children: A systematic review and meta-analysis

INTRODUCTION

This systematic review and meta-analysis investigate the long-term effects of primary school-based obesity prevention interventions on body-mass index (and z-scores), waist circumference (and z-scores) and weight status.

METHODS

Four databases were searched for studies from date of inception until June 8th, 2021. We included randomized controlled trials (RCT) and non-RCTs investigating effects ≥12 months post-intervention of primary school-based interventions with intervention duration ≥6 months and containing a diet and/or physical activity component on outcomes of interest. Articles were assessed on risk of bias and methodological quality by RoB2 and ROBINS-I. Meta-analysis was performed and results were narratively summarized. Evidence quality was assessed with GRADE.

RESULTS

Nineteen studies were included, 9 were pooled in a meta-analysis. No long-term effects were found on body-mass index (+0.06 kg/m² ; CI95% = -0.38, 0.50; I²  = 66%), body-mass index z-scores (-0.08; CI95% = -0.20, 0.04; I²  = 36%), and waist circumference (+0.57 cm; CI95% = -0.62, 1.75; I²  = 13%). Non-pooled studies reported mixed findings regarding long-term effects on body-mass index, body-mass index z-scores and weight status, and no effects on waist circumference and waist circumference z-scores. Evidence certainty was moderate to very low.

DISCUSSION

No clear evidence regarding long-term effects of primary school-based interventions on obesity-related outcomes was found. Recommendations for further research and policy are discussed. Prospero registration ID: CRD42021240446.

Longitudinal associations between parent, child, family factors and dyssomnias in children from birth to 8 years: The CIKEO study

BACKGROUND

Dyssomnias, are the most common parent-reported sleep complaints in young children. The present study investigated the prevalence, one-year development (incidence and persistence) of dyssomnia in early childhood, and the parent, child, and family factors associated with dyssomnia.

METHODS

Longitudinal data of 700 children aged 0-8, gathered in the CIKEO cohort study in the Netherlands were analyzed. Dyssomnias were defined as the presence of night awakenings ≥3 times per night or sleep-onset latency of >30 min. Least absolute shrinkage and selection operator (LASSO) was used to identify the parental, child, and family factors associated with the incidence and persistence of dyssomnias in children.

RESULTS

The mean age of the children (47 % girls) was 3.2 ± 1.9 years at baseline and 4.4 ± 1.8 years at follow-up. The prevalence of dyssomnias was 13.3 % and 15.4 % at baseline and follow-up, respectively. The incidence and persistence rates of dyssomnias at follow-up were 12.0 % and 37.6 %, respectively. New incidence of insomnia was associated with being a girl, having medical conditions, experiencing stressful life events, and lower parenting self-efficacy at baseline (P < 0.05). Higher levels of parental psychological distress were associated with the persistence of dyssomnias in children (P < 0.05).

CONCLUSIONS

Dyssomnias are common with a moderate persistent rate in young children. Several parental, child, and family factors in relation to the incidence and persistence of dyssomnias were identified. Preventive programs and interventions targeting modifiable factors, particularly parental psychological distress, parenting self-efficacy, and resilience to stressful life events, might benefit child sleep.

Clustering of characteristics associated with unplanned pregnancies: the generation R study

Background

Unplanned or unintended pregnancies form a major public health concern because they are associated with unfavorable birth outcomes as well as social adversity, stress and depression among parents-to-be. Several risk factors for unplanned pregnancies in women have previously been identified, but studies usually take a unidimensional approach by focusing on only one or few factors, disregarding the possibility that predictors might cluster. Furthermore, data on predictors in men are largely overlooked. The purpose of this study is to determine predictors of unplanned versus planned pregnancy, to determine predictors of ambivalent feelings regarding pregnancy, and to investigate how characteristics of men and women with an unplanned pregnancy cluster together.

Methods

This study was embedded in Generation R, a multiethnic population-based prospective cohort from fetal life onwards. Pregnancy intention was reported by 7702 women and 5367 partners. Information on demographic, mental, physical, social, and sexual characteristics was obtained. Logistic regression, multinomial regression and cluster analyses were performed to determine characteristics that were associated with an unplanned pregnancy, with ambivalent feelings regarding the unplanned pregnancy and the co-occurrence of characteristics in women and men with unplanned pregnancy.

Results

Twenty nine percent of the pregnancies were unplanned. Logistic regression analyses showed that 42 of 44 studied predictors were significantly associated with unplanned pregnancy. The most important predictors were young age, migration background, lower educational level, lower household income, financial difficulties, being single, lower cognitive ability, drug use prior to pregnancy, having multiple sexual partners in the year prior to the pregnancy, younger age of first sexual contact and a history of abortion. Multinomial regression analyses showed that a Turkish or Moroccan background, Islamic religion, little financial opportunities, being married, having ≥3 children, high educational level, more mental health and social problems and older age of first sexual contact were associated with prolonged ambivalent feelings regarding pregnancy. Different combinations of characteristics were observed in the four clusters of women and men with unplanned pregnancy.

Conclusions

Many predictors are related with unplanned pregnancies, ambivalent feelings toward the pregnancy, and we identified very heterogeneous groups of women and men with unplanned pregnancies. This calls for heterogeneous measures to prevent unplanned pregnancies.

A prospective study on the association between social support perceived by parents of children aged 1-7 years and the use of community youth health care services

Aim

This study examined the association between social support perceived by parents of children aged 1-7 years and the use of additional community youth health care services.

Methods

Data of 749 parents of children aged 1-7 years, gathered in the CIKEO cohort study in the Netherlands, were analyzed. Social support was assessed with the Multidimensional Scale of Perceived Social Support. Data on the use of additional community youth health care services during a period of 1.5 years were obtained from the electronic records of participating youth health care organizations. Multivariable logistic regression models were used to examine the association between perceived social support and the use of additional youth health care services and to explore moderation by the parent's educational level.

Results

The mean age of the responding parents was 33.9 years (SD = 5.1); 93.6% were mothers. Parents who perceived low to moderate levels of social support had 1.72 (95% CI: 1.11, 2.66) times higher odds of using one or more additional youth health care services during the study period compared to parents who perceived high levels of social support at baseline. This association was independent of predisposing factors, but not independent of need factors (p > 0.05). Furthermore, the association was moderated by the educational level of the parent (p = 0.015). Among parents with a high educational level, low to moderate levels of perceived social support at baseline were associated with 2.93 (95% CI: 1.47, 5.83) times higher odds of using one or more additional youth health care services during the study period independent of predisposing and need factors. Among parents with a low or middle educational level the association between perceived social support and use of additional youth health care services was not significant.

Conclusion

Our findings provide evidence that low to moderate levels of perceived social support are associated with a higher use of additional community youth health care services among parents of children aged 1-7 years, especially among high educated parents. Recommendations for policy and practice are provided.

Contextual determinants associated with children's and adolescents' mental health care utilization: a systematic review

Determinants at the contextual level are important for children's and adolescents' mental health care utilization, as this is the level where policy makers and care providers can intervene to improve access to and provision of care. The objective of this review was to summarize the evidence on contextual determinants associated with mental health care utilization in children and adolescents. A systematic literature search in five electronic databases was conducted in August 2021 and retrieved 6439 unique records. Based on eight inclusion criteria, 74 studies were included. Most studies were rated as high quality (79.7%) and adjusted for mental health problems (66.2%). The determinants that were identified were categorized into four levels: organizational, community, public policy or macro-environmental. There was evidence of a positive association between mental health care utilization and having access to a school-based health center, region of residence, living in an urban area, living in an area with high accessibility of mental health care, living in an area with high socio-economic status, having a mental health parity law, a mental health screening program, fee-for-service plan (compared to managed care plan), extension of health insurance coverage and collaboration between organizations providing care. For the other 35 determinants, only limited evidence was available. To conclude, this systematic review identifies ten contextual determinants of children's and adolescents' mental health care utilization, which can be influenced by policymakers and care providers. Implications and future directions for research are discussedPROSPERO ID: CRD42021276033.

Effectiveness of the Promising Neighbourhoods community program in 0-to 12-year-olds A difference-in-difference analysis

Objective

The purpose of this study was to evaluate a collaborative community-based program that aims to a) increase the health, safety and talent development of youth, and b) contribute to the reduction of socioeconomic inequalities.

Methods

A difference-in difference design with two separate cross-sectional samples in 2018 (n = 984) and 2021 (n = 413) among 0- to 12-year-olds with an intervention and comparator condition was used. The program, called Promising Neighbourhoods, consists of collaboration with community stakeholders, data-based priority setting, knowledge-and theory-based policies, and evidence-based interventions. The program was implemented in three neighbourhoods which were compared with three similar comparator neighbourhoods in which the program was not implemented. Logistic difference-in-difference regression was used to test effectiveness of the intervention on informal parenting support, outdoor-play, sport club membership, general health and risk of emotional and behavioural difficulties and to examine differences in intervention effects between children with a lower or higher socioeconomic status.

Results

A significant intervention effect of the Promising Neighbourhoods program after two-years was found for outdoor-play (OR 0.61; 95%CI 0.37, 0.99). No other significant intervention effects were found for other outcomes. No different interventions effects were found for children with a lower or higher socioeconomic status on outcomes.

Conclusion

The findings of this study indicate a positive intervention effect for one of the outcomes in 0- to 12-year-olds. Further mixed-methods evaluation research and using longer follow-up periods are needed to examine the value of these type of programs. Further development of Promising Neighbourhoods seems warranted.

Trial registration

This study was prospectively registered in the Netherlands National Trial Register (Number: NL7279) on 26 September 2018.

•

A collaborative neighbourhood program involving stakeholders was evaluated.

•

The program included joint priority setting to promote child health/well-being.

Role of neighbourhood social characteristics in children's use of mental health services between ages 9 and 13 years: a population-based cohort study in the Netherlands

OBJECTIVES

This study aims to investigate the association of neighbourhood socioeconomic status (SES) and social cohesion (SC) within the neighbourhood with mental health service use in children, independent of individual-level characteristics and mental health problems.

DESIGN, SETTING AND PARTICIPANTS

A longitudinal analysis was done using data from the Generation R Study, a prospective, population-based cohort of children born in Rotterdam, the Netherlands. These data were linked to the Neighbourhood Profile, containing registry and survey data on residents of Rotterdam. Data of 3403 children (mean age: 13.6 years, SD: 0.4) were used to study the associations between neighbourhood SES, SC (SC belonging and SC relations) and mental health service use, adjusted for mental health problems and sociodemographic characteristics.

OUTCOME MEASURES

Mental health service use was reported by the accompanying parent at the research centre using the question: 'Did your child visit a psychologist or psychiatrist between 9 and 13 years old?'.

RESULTS

Mental health services were used by 524 (15.4%) children between ages 9 and 13 years. No significant differences in mental health service use between neighbourhoods were identified (median OR: 1.07 (p=0.50)). The neighbourhood social characteristics were associated with mental health service use, but only when adjusted for each other. Children living in neighbourhoods with a low SES (OR 0.57 (95% CI 0.32 to 1.00)) or high SC belonging (OR 0.79 (95% CI 0.64 to 0.96)) were less likely to use services compared with children in a high SES or low SC belonging neighbourhood. SC relations was not associated with mental health service use.

CONCLUSIONS

Our findings indicate that children living in high SES neighbourhoods or in neighbourhoods where people feel less sense of belonging are more likely to use mental health services. As these associations were only present when studied jointly, more research is warranted on the complex associations of neighbourhood factors with children's mental health service use.

Associations of socioeconomic status indicators and migrant status with risk of a low vegetable and fruit consumption in children

Background

It is important to provide insight in potential target groups for interventions to reduce socioeconomic inequalities in children's vegetable/fruit consumption. In earlier studies often single indicators of socioeconomic status (SES) or migrant status have been used. However, SES is a multidimensional concept and different indicators may measure different SES dimensions. Our objective is to explore multiple associations of SES indicators and migrant status with risk of a low vegetable/fruit consumption in a large multi-ethnic and socioeconomically diverse sample of children.

Methods

We included 5,010 parents of 4- to 12-year-olds from a Dutch public health survey administered in 2018. Cross-sectional associations of parental education, material deprivation, perceived financial difficulties, neighbourhood socioeconomic status (NSES) and migrant status with low (≤4 days a week) vegetable and fruit consumption in children were assessed using multilevel multivariable logistic regression models. Results are displayed as odds ratios (OR) with 95% confidence intervals (CI).

Results

Of the 4- to 12-year-olds, 22.1% had a low vegetable consumption and 11.9% a low fruit consumption. Low (OR 2.51; 95%CI: 2.05, 3.07) and intermediate (OR 1.83; 95%CI: 1.54, 2.17) parental education, material deprivation (OR 1.45; 95%CI: 1.19, 1.76), low NSES (OR 1.28; 95%CI: 1.04, 1.58) and a non-Western migrant status (OR 1.94; 95%CI: 1.66, 2.26) were associated with a higher risk of a low vegetable consumption. Low (OR 1.68; 95%CI: 1.31, 2.17) and intermediate (OR 1.39; 95%CI: 1.12, 1.72) parental education and material deprivation (OR 1.63; 95%CI: 11.27, 2.08) were also associated with a higher risk of a low fruit consumption.

Conclusion

Our findings indicate associations of multiple SES indicators and migrant status with a higher risk of a low vegetable/fruit consumption in children and thus help to identify potential target groups.

•

Vegetable and fruit consumptions on 4 days or less a week is reported for respectively 22.1% and 11.9% of children.

•

Children's vegetable but not fruit consumption differs between neighbourhoods.

•

A non-Western migrant status and a low socio-economic status of the neighbourhood are associated with low vegetable consumption.

•

Low/intermediate education and material deprivation are associated with low vegetable and fruit consumption.

•

This study provides clues to potential entry points for reducing inequalities in vegetable and fruit consumption.

Changes in youth care use after the implementation of community-based support teams: repeated measurement study using registry data and data on team characteristics

OBJECTIVES

New legislation on youth care in the Netherlands led to the implementation of community-based support teams, providing integrated primary youth care. Important aims of the new Youth Act were more integrated, timely care and less use of intensive forms of care. Our aim was to study changes in youth care use in time and the role of newly introduced community-based support teams herein.

SETTING

Register data (2015-2018) on youth of a large city were linked and combined with administrative and aggregated data on team characteristics.

PARTICIPANTS

Data on 126 095 youth (0-18 years) were available for analyses.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary, specialised and residential youth care use were the primary outcomes.

RESULTS

Generalised estimating equations analyses adjusted for individual characteristics demonstrated that over 4 years, use of primary youth care increased from 2.2% to 8.5% (OR 1.70; 99% CI 1.67 to 1.73), specialised youth care decreased from 7.2% to 6.4% (OR 0.98; 99% CI 0.97 to 1.00) and residential youth care increased slightly (OR 1.04; 99% CI 1.01 to 1.06). Gender, age, family status, migrant background and educational level were all associated with the types of youth care use and also with some trends in time. Likelihood to receive care increased in time for preschool and younger children but did not improve for migrant children.Case load, team size, team turnover, team performance and transformational leadership showed significant associations with different types of youth care use but hardly with trends in time.

CONCLUSION

Patterns of youth care use changed towards more locally provided primary youth care, slightly less specialised and slightly more residential youth care. Furthermore, youth care use among younger children increased in time. These trends are partly in line with the trends intended by the Youth Act. Little evidence was found for the role of specific team characteristics on changes in youth care use in time.

The Association between Stressful Life Events and Emotional and Behavioral Problems in Children 0-7 Years Old: The CIKEO Study

Background: Stressful life events (SLEs) are recognized risk factors for emotional and behavioral problems, but the association is understudied among young children. Our aim was to examine the association between exposure to SLEs and emotional and behavioral problems in young children up to 7 years old. Methods: We analyzed baseline data from 959 children (mean age = 3.3 years; SD = 1.9; 47.5% girls) in the CIKEO study, a community-based longitudinal study in the Netherlands. Linear regression was used to assess the associations between the total as well as the individual exposure to SLEs experienced in the past 12 months, and emotional and behavioral problems assessed by CBCL 1.5-5. Interactions of SLEs and child age, sex, ethnic background, and socioeconomic status were explored. Results: Higher total exposure to SLEs, as indicated by the number of SLEs, was significantly associated with higher CBCL total, internalizing and externalizing problem scores (p for trend < 0.05). The results did not differ by child age, sex, ethnic background, or family SES. Six out of the 12 SLEs explored were independently associated with greater CBCL total/externalizing/internalizing scores (p < 0.05). Conclusions: Exposure to SLEs is associated with higher levels of emotional and behavioral problems in young children, and the impact of SLEs may vary depending on the types of events. Stressful life events might be a useful target for interventions to improve emotional and behavioral well-being among young children.

Teacher-reported emotional and behavioural problems and ethnic background associated with children's psychosocial care use: a longitudinal population-based study

Approximately, 15% of children in Western countries suffer from emotional and behavioural problems. However, not all children receive the psychosocial care they need, especially children with a non-Western background experience an unmet need for care. This might be because parents of non-Western children report a lower need for care than parents of Western children, unrelated to the actual need. This study examined the association between teacher-reported problems and psychosocial care use, independent of mother-reported problems. Further, the role of ethnic background in this association was investigated. The study sample of 9-year-old children was retrieved from the Generation R Study (N = 3084), a prospective, population-based cohort of children born in Rotterdam, the Netherlands. Teacher- and mother-reported problems were measured via questionnaire when the children were  6/7 years old. Psychosocial care use was mother-reported at the research centre when children were 9 years old (8.1%). Hierarchical logistic regressions showed significant positive associations between teacher-reported total, externalising and internalising problems and later psychosocial care use. These associations were independent of mother-reported problems. Children with a non-Western background used less care, but ethnic background did not moderate the association between teacher-reported problems and care use. Our findings suggest that teachers might have an important role, next to parents, in the identification of problems and children's access to care. This may be particularly important for non-Western children, as they use less psychosocial care than Western children, despite other research showing that they generally display higher levels of problems. Directions for future research and implications are discussed.

Associations between organised leisure-time activities and mental health problems in children

Previous studies conducted mainly among adolescents have found associations between participation in sport organised leisure-time activities (OLTAs) and mental health problems (MHP). Fewer research studies have been performed to primary school-aged children and to organised non-sport OLTAs. Therefore, the objective is to examine whether there is an association between participation in sport and non-sport OLTAs and a high risk of MHP in 4- to 12-year-olds. Data were used on 5010 children from a cross-sectional population-based survey conducted between May and July 2018 in Rotterdam, the Netherlands. Associations between sport OLTAs, non-sport OLTAs and breadth of OLTAs and a high risk of MHP were explored using logistic regression models adjusting for sociodemographic characteristics, stressful life events and physical activity. Of all children, 58% participated in sport OLTAs and 22% in non-sport OLTAs. The proportion of children with high risk of MHP among participants in sport OLTAs is smaller than among non-participants (OR 0.66, 95% CI: 0.53, 0.81). The proportion of children with high risk of MHP among participants in non-sport OLTAs is smaller than among non-participants (OR 0.69, 95% CI: 0.53, 0.91). The proportion of children with a high risk of MHP among participants in 1 category of OLTAs (OR 0.61, 95% CI: 0.49, 0.76) and in 2-5 categories of OLTAs (OR 0.48, 95% CI: 0.32, 0.71) is smaller than among non-participants.  Conclusion: The proportion of children with high risk of MHP among participants in OLTAs is smaller than among non-participants. What is Known: • Around 10--20% of children and adolescents experiences mental health problems. • Sport organised leisure-time activities have been found to be associated with a lower risk of mental health problems in adolescents. What is New: • The proportion of children with a high risk of mental health problems in participants in organised leisure-time activities is smaller than among non-participants. • The proportion of children with a high risk of mental health problems in participants with a higher breadth of organised leisure-time activities is smaller compared to non-participants.

Parental, child and socio-contextual factors associated with parenting self-efficacy among parents of children aged 0-7 years old: the CIKEO study

BACKGROUND

A high parenting self-efficacy (PSE) has been associated with positive parenting and positive child development. However, there is limited and inconsistent information on factors associated with PSE.

OBJECTIVE

To investigate factors associated with PSE in parents of children aged 0-7 years old, and to explore whether the associations were different between mothers and fathers.

METHODS

We performed a cross-sectional analysis of the baseline data from a prospective cohort study: the CIKEO study. A total of 1012 parents (mean age = 33.8, SD = 5.0) completed self-reported measure of PSE and 18 potential factors associated with PSE.

RESULTS

Multivariable models revealed that lower parenting stress, fewer child behavior problems, better eating behavior, better parental and child general health, a smaller number of children living in the household, higher perceived level of social support and having a migration background were associated with higher levels of PSE (p < 0.05). The association between family functioning and PSE differed between mothers and fathers (p for interaction = 0.003): with beta and 95% confidence interval being: 1.29 (- 2.05, 0.87), and 0.23 (- 0.46, 3.29), respectively.

CONCLUSIONS

A range of parental, child and social-contextual factors in relation to PSE were identified. The patterns of associations for most of the factors were similar among mothers and fathers. However, the association between family functioning and PSE might differ for mothers and fathers. Our findings are relevant for tailoring and implementing successful interventions and effective policy making in child care.

Factors associated with media use for parenting information: A cross-sectional study among parents of children aged 0-8 years

Aim

Media use may strengthen parents’ capacities to deal with parenting issues. This study examined which factors are associated with media use for parenting information.

Design

Cross‐sectional data of 658 parents of children aged 0–8 years, gathered in the CIKEO cohort study in the Netherlands, were analysed.

Methods

Multivariable logistic regression models were used to examine which factors were associated with media use for parenting information.

Results

The mean age of the participants was 33.8 years (SD = 5.0); 94.7% were mothers; 77.4% used media for parenting information. Parents with more questions or concerns (OR: 1.40, 95% CI: 1.23, 1.59), and parents who received parenting information from their social contacts (OR: 5.57, 95% CI: 3.22, 9.61), had higher odds of media use for parenting information. Older parents (OR: 0.95, 95% CI: 0.91, 1.00), and parents of older children (OR: 0.84, 95% CI: 0.74, 0.95), had lower odds of media use for parenting information.

The role of the teacher in identifying (non-Western) children in need for psychosocial care

Background

The prevalence of mental health problems in Europe is higher among children with a non-Western than a Western background. Nevertheless, non-Western children use less psychosocial care. A possible explanation is the differences in parents' perceived need for care. Non-Western parents generally have a lower perceived need, which calls for other significant adults in the children's life to identify this need. This study investigates whether teachers could fulfil a role in identifying mental problems, especially in non-Western children, to improve the access to care.

Methods

The study sample of 9-year-old children was retrieved from the Generation R Study (N = 3,084), a population-based cohort of children born in Rotterdam, the Netherlands. Teacher- and mother-reported problems were measured at 6 years via questionnaires. Psychosocial care use was mother-reported at the research centre at 9 years (8.1% used care).

Results

Our findings showed that, among children who used care, elevated problem levels at 6 years were reported for 10% by mothers and teachers, for 16% by mothers only and for 22% by teachers only. Hierarchical logistic regressions showed that having teacher-reported problems was associated with psychosocial care use (OR:3.06, p&lt;.05), also after adjusting for mother-reported problems (OR:2.83, p&lt;.05). Ethnic background did not moderate this association. Nonetheless, non-Western children did use significantly less care than Western children (OR:.58, p&lt;.05), irrespective of their problem level.

Conclusions

The association between teacher-reported problems and psychosocial care use suggests that teachers can play a role in identifying mental problems in children, in addition to parents. The role of the teacher might be particularly important for non-Western children in Western countries as their parents report on average a lower need for care, irrespective of the actual need. This calls for prevention strategies that focus on the teacher's unique position.

Key messages

Teachers have an important role in the identification of mental health problems and access to psychosocial care for children. The signalling function of teachers is extra important for children with a non-Western migrant background as this group uses less care, irrespective of their problem level.

Study protocol for the evaluation of long-term effects of the school-based obesity prevention program Lekker Fit! ('enjoy being fit'): a retrospective, controlled design

INTRODUCTION

Preventive interventions to reduce overweight and obesity in childhood and adolescence are studied on their effectiveness worldwide. A number with positive results. However, long-term effects of these interventions and their potentially wider influence on well-being and health have been less studied. This study aims to evaluate the long-term effects of a multicomponent intervention in elementary school children targeting individual behaviour as well as environment (Lekker Fit!). The primary outcomeis body mass index and the secondary outcomes are waist circumference, weight status, physical fitness, lifestyle, psychosocial health and academic performance.

METHODS AND ANALYSIS

In a naturalistic effect evaluation with a retrospective, controlled design adolescents in secondary schools, from intervention and non-intervention elementary schools, will be compared on a wide set of outcome variables. Data will be collected by questionnaires and through anthropometric and fitness measurements by trained physical education teachers and research assistants. Baseline data consist of measurements from the adolescents at the age of 5 years old and are gathered from preventive youth healthcare records, from before the intervention took place. Multilevel regression models will be used and adjusted for baseline measurements and potential confounding variables on the individual and environmental level. Furthermore, propensity scores will be applied.

ETHICS AND DISSEMINATION

The study has been approved by the Medical Research Ethics Committee of the Erasmus Medical Centre, Rotterdam, The Netherlands (permission ID: MEC-2020-0644). Study findings will be disseminated in peer-reviewed journals and by conference presentations.

Changes in Family Poverty Status and Child Health

OBJECTIVES

In this study, we aim to assess the associations over time between poverty and child weight status, asthma, and health-related quality of life (HRQoL).

METHODS

We analyzed data for 3968 children from the Generation R Study, a population-based cohort study in the Netherlands. Net household income and the number of adults and children living from this income were measured at 4 time-points (during pregnancy and at ages 2, 3, and 6). Poverty was defined on the basis of the equivalized household income being <60% of the median national income. Child health outcomes were measured at age 6 years. The association was explored by using logistic and linear regression models.

RESULTS

In this cohort, 9.8% of children were born into poverty and 6.0% had experienced 3 to 4 episodes of poverty. Independent of current poverty status, children born into poverty had an odds ratio (OR) of 1.68 for having overweight/obesity and a lower physical HRQoL (OR = -1.32) than those not born into poverty. Children having experienced 3 to 4 episodes of poverty had an OR of 1.94 for having asthma and a lower physical HRQoL (OR = -3.32) compared with children from never-poor families. Transition out of poverty before age 2 was associated with lower risk of asthma and a higher physical HRQoL compared with children who remained in poverty.

CONCLUSIONS

Being born into poverty or experiencing multiple episodes of poverty is associated with negative child health outcomes, such as having overweight, asthma, or a lower HRQoL. Support for children and families with a low household income is warranted.

Identifying patterns of lifestyle behaviours among children of 3 years old

BACKGROUND

To identify the patterns of lifestyle behaviours in children aged 3 years, to investigate the parental and child characteristics associated with the lifestyle patterns, and to examine whether the identified lifestyle patterns are associated with child BMI and weight status.

METHODS

Cross-sectional data of 2090 children 3 years old participating in the Dutch BeeBOFT study were used. Child dietary intakes, screen times and physical activity were assessed by parental questionnaire, and child weight and height were measured by trained professionals according to a standardized protocol. Latent class analysis was applied to identify patterns of lifestyle behaviours among children.

RESULTS

Three subgroups of children with distinct patterns of lifestyle behaviours were identified: the 'unhealthy lifestyle' pattern (36%), the 'low snacking and low screen time' pattern (48%) and the 'active, high fruit and vegetable, high snacking and high screen time' pattern (16%). Children with low maternal educational level, those raised with permissive parenting style (compared those with authoritative parents), and boys were more likely be allocated to the 'unhealthy lifestyle' pattern and the 'active, high fruit and vegetable, high snacking and high screen time' pattern (P < 0.05). No association was found between the identified lifestyle patterns and child BMI z-score at age 3 years.

CONCLUSIONS

Three different lifestyle patterns were observed among children aged 3 years. Low maternal educational level, permissive parenting style and male gender of the child were associated with having unhealthy lifestyle patterns for the child.

Independent contributions of family and neighbourhood indicators of socioeconomic status and migrant status to risk of mental health problems in 4-12 year old children

Rationale

A range of family and neighbourhood indicators of socioeconomic status and migrant status have been shown to be associated with risk of mental health l problems (MHP) in children. In this study we determined the independent contributions of these indicators.

Objectives

The main objective is to examine independent associations of family and neighbourhood socioeconomic status indicators and migrant status with risk of MHP in children.

Methods

We analyzed data from an anonymous public health survey among 5010 parents/caretakers of children aged 4–12 years living in Rotterdam, The Netherlands, gathered in 2018. Outcome of interest was risk of MHP measured using the total difficulties score of the Strengths and Difficulties Questionnaire. Associations of parent-reported perceived financial difficulties, material deprivation (not being able to provide certain goods, or leisure, educational or cultural activities or care use for children due to financial restrictions), parental educational level, child's migrant status and neighbourhood socioeconomic status with risk of MHP and with the total difficulties score were assessed using multilevel multivariable logistic and linear regression models.

Results

In total, 473 (9.5%) children had a high risk of MHP. We observed independent associations of perceived financial difficulties, material deprivation and parental educational level with risk of MHP and with an increase in total difficulties score (P < 0.05). Migrant status and neighbourhood socioeconomic status were not independently associated with risk of MHP or a change in total difficulties score.

Conclusions

Already in early life, perceived financial difficulties by parents, material deprivation reported by parents and lower parental education appeared to be independently associated with the risk of MHP in 4–12 year olds. Health professionals should be aware of the relatively higher risks in these subgroups and consider policies address this.

Associations between family and home-related factors and child's snack consumption in a multi-ethnic population

BACKGROUND

Energy-dense snacks are considered unhealthy due to their high concentrations of fat and sugar and low concentrations of micronutrients. The present study aimed to evaluate associations between family and home-related factors and children's snack consumption. We explored associations within subgroups based on ethnic background of the child.

METHODS

Cross-sectional data of 644 primary school children (mean age: 9.4 years, 53% girls) from the population-based 'Water Campaign' study conducted in the Netherlands were used. Logistic regression analyses were used to evaluate the associations between family and home-related factors and child's snack intake.

RESULTS

Of the children, 28.7% consumed more than one snack per day. Children of parents who expressed more restrictive parenting practices towards the child's snack consumption (odds ratio (OR) = 2.5, P < 0.001), and who modelled snack eating less often (OR = 2.2, P < 0.001) had lower snack intake. Restrictive parenting practices and parental modelling of healthy snacking were significant for children with a Dutch or Moroccan/Turkish ethnic background, but not for children with a Surinamese/Antillean ethnic background.

CONCLUSIONS

We observed that parenting practices and parental modelling were independently associated with the child's snack intake. Also, the relationships between these factors and the child's snack consumption differed for children with distinct ethnic backgrounds.

Clustering of Sedentary Behaviours, Physical Activity, and Energy-Dense Food Intake in Six-Year-Old Children: Associations with Family Socioeconomic Status

This study examined the clustering of lifestyle behaviours in children aged six years from a prospective cohort study in the Netherlands. Additionally, we analysed the associations between socioeconomic status and the lifestyle behaviour clusters that we identified. Data of 4059 children from the Generation R Study were analysed. Socioeconomic status was measured by maternal educational level and net household income. Lifestyle behaviours including screen time, physical activity, calorie-rich snack consumption and sugar-sweetened beverages consumption were measured via a parental questionnaire. Hierarchical and non-hierarchical cluster analyses were applied. The associations between socioeconomic status and lifestyle behaviour clusters were assessed using logistic regression models. Three lifestyle clusters were identified: “relatively healthy lifestyle” cluster (n = 1444), “high screen time and physically inactive” cluster (n = 1217), and “physically active, high snacks and sugary drinks” cluster (n = 1398). Children from high educated mothers or high-income households were more likely to be allocated to the “relatively healthy lifestyle” cluster, while children from low educated mothers or from low-income households were more likely to be allocated in the “high screen time and physically inactive” cluster. Intervention development and prevention strategies may use this information to further target programs promoting healthy behaviours of children and their families.

Evaluation of effectiveness of (elements of) parenting support in daily practice of preventive youth health care; design of a naturalistic effect evaluation in 'CIKEO' (consortium integration knowledge promotion effectiveness of parenting interventions)

BACKGROUND

The number of interventions to support parents is growing. The level of evidence regarding these intervention varies. In this paper we describe a study that aims to assess the effectiveness of specific 'elements' within such parenting interventions for families with children up to 7 years. A naturalistic effect evaluation will be applied. Study questions are: 1. What is the exposure of parents to (elements of) parenting interventions in the daily practice of preventive youth health care? 2. What are the associations between the exposure to (elements of) parenting interventions and outcomes in parents/children related to parenting and child development?

METHODS/DESIGN

Thousand parents/caregivers are recruited by preventive youth health care providers in the Netherlands. Measurements will be performed after inclusion and after 12-months follow up. Data regarding child/parent/caregiver characteristics, use of (parenting) interventions and care, and outcomes with regard to parenting skills, family functioning and child development will be collected. Outcomes will be compared between parents/children exposed and non-exposed to the (elements of) parenting interventions (adjusting for confounders).

DISCUSSION

We hypothesize that parents/caregivers with exposure to (elements of) parenting interventions show (relatively more) improvements in parenting outcomes. Results will support intervention selection/development, and support communities/professionals to select appropriate intervention-elements.

Sleep and body mass index in infancy and early childhood (6-36 mo): a longitudinal study

BACKGROUND

Relatively, few longitudinal studies have evaluated the association between sleep and body mass index (BMI) among younger children. In addition, few studies have evaluated the bidirectional longitudinal association between sleep duration and child BMI.

OBJECTIVE

The objective of the study is to determine in children aged 6 to 36 months (1) the cross-sectional association of sleep duration and sleep problems with child BMI z score, (2) whether sleep duration predicts changes in child BMI z score, and (3) and whether BMI z score can predict changes in child sleep duration.

METHODS

This study used longitudinal data from the BeeBOFT study (N = 2308). Child sleep duration and sleep problems (indicated by night awakenings and sleep-onset latency) were parent reported, and child BMI was measured using a standardized protocol by trained healthcare professionals at approximately 6, 14, and 36 months of age. Linear mixed models and linear regression models were applied to assess the cross-sectional and bidirectional longitudinal associations between sleep and BMI z scores.

RESULTS

Cross sectionally, shorter sleep duration was associated with higher BMI z scores at 14 (β = -0.034, P < 0.05) and 36 months (β = -0.045, P < 0.05). Sleep duration at 6 or 14 months did not predict BMI z score at either 14 or 36 months. Higher BMI z scores at 6 months predicted shorter sleep duration (hours) at 14 months (β = -0.129, P < 0.001). No association was found between sleep problems and child BMI z scores.

CONCLUSIONS

Cross-sectional associations between shorter sleep duration and higher BMI z score emerged in early childhood (age 14 and 36 mo). Higher BMI z scores may precede shorter sleep duration but not vice versa.

Evaluation of the promising neighbourhoods community program to reduce health inequalities in youth: a protocol of a mixed-methods study

BACKGROUND

Reducing socioeconomic health inequalities among youth is a major challenge for governments around the world and reports on successful attempts are scarce. Socioecological and integral approaches with collaborative partnerships and community engagement are recommended but knowledge about the effectiveness and effective and ineffective elements is limited. The Promising Neighbourhoods program employs such an approach aiming to reduce socioeconomic inequalities in health, safety and talent development in youth. We will evaluate the process-implementation, and effectiveness of the Promising Neighbourhoods program.

METHODS/DESIGN

Core elements of Promising Neighbourhoods are a collaborative community programming approach with stakeholders, data-based priority setting, knowledge-, and theory-based policies and evidence-based interventions. Community stakeholders and key-leaders from the neighbourhoods are engaged in the program. For this evaluation study the program will be implemented in three intervention neighbourhoods. These neighbourhoods will be compared to three control neighbourhoods at baseline in 2018/2019 and at follow-up in 2020/2021 after full implementation of the Promising Neighbourhoods program. Intervention neighbourhoods receive a tailored intervention-package including evidence-based interventions and additional measures by community stakeholders. In control neighbourhoods, no special planning will take place thus interventions are offered as usual. A mixed-methods approach following the stages of the logic model from program is applied for this evaluation. Questionnaires, focus groups, and registration data will be collected among community stakeholders, key-leaders, and youth to evaluate the process-implementation of the program. Indicators of intermediate and ultimate outcomes will be studied among N = 818 children and N = 818 youngsters using difference-in-difference regression analysis to evaluate the effectiveness of the Promising Neighbourhoods program.

DISCUSSION

Hypotheses are that a collaborative community approach with stakeholders leads to clear priority-setting and better tailored interventions of better quality. We further hypothesise a decline in socioeconomic inequalities in intermediate and ultimate outcomes for health, safety and talent development in the intervention neighbourhoods in comparison to control neighbourhoods. The results add knowledge about effective and ineffective elements of collaborative community programming approaches to reduce health inequalities in youth and thus are relevant for local and national public health authorities.

Different Perspectives on Predictability and Preventability of Surgical Readmissions

BACKGROUND

Although unscheduled readmissions are increasingly being used as a quality indicator, only few readmission studies have focused on surgical patient populations.

METHODS

An observational study "CURIOS@" was performed at three centers in the Netherlands. Readmitted patients and treating doctors were surveyed to assess the discharge process during index admission and their opinion on predictability and preventability of the readmission. Risk factors associated with predictability and preventability as judged by patients and their doctor were identified. Cohen's kappa was calculated to measure pairwise agreement of considering readmission as predictable/preventable. PRISMA root cause categories were used to qualify the reasons for readmission.

RESULTS

In 237 unscheduled surgical readmissions, more patients assessed their readmissions to be likely preventable compared with their treating doctors (28.7% versus 6.8%; kappa, 0.071). This was also reflected in poor consensus about risk factors and root causes of these readmissions. When patients reported that they did not feel ready for discharge or requested their doctor to allow them to stay longer at discharge during index admission, they deemed their readmission more likely predictable and preventable. Doctors focused on measurable factors such as the clinical frailty scale and biomarkers during discharge process. Health-care worker failures were strongly associated with preventable readmissions.

CONCLUSIONS

There is no consensus between readmitted patients and treating doctors about predictability and preventability of readmissions, nor about associated risk factors and root causes. Patients should be more effectively involved in their discharge process, and the relevance of optimal communication between them should be emphasized to create a safe and efficient discharge process.

Effectiveness of interventions to improve lifestyle behaviors among socially disadvantaged children in Europe

Background

Unhealthy lifestyle behaviors and childhood overweight are more common among children from families with a low socioeconomic position and ethnic minority children (referred to as social disadvantaged children). : This systematic review evaluates the effectiveness of interventions aimed to improve lifestyle behaviours and/or prevent overweight among socially disadvantaged children in Europe. : Six major databases were searched for studies reporting intervention effects on adiposity measures, sedentary behaviours, physical activity behaviours or dietary behaviours. Studies were included when the study sample consisted of at least 50% socially disadvantaged children or when results were presented for subgroups of socially disadvantaged children separately. Methodological quality assessment was based on Cochrane criteria. In total, 11 studies reporting on eight interventions (one among infants 0-2 years, one among preschoolers 2-6 years, six among school-aged children 6-12 years) were identified. Of these eight interventions, five interventions primarily aimed to improve at least one adiposity measure and three primarily aimed to improve a specific lifestyle behaviour. In general, modest positive effects were found but interventions were limited by a short follow-up duration. Despite an urgent need for effective interventions to improve lifestyle behaviours and prevent overweight among socially disadvantaged children, research on the effectiveness of interventions in Europe is still scarce. Those interventions that have been evaluated show modest effects on lifestyle behaviours and adiposity measures, but long-term follow-up is needed to establish whether these effects are sustained over a longer period of time.

A Method for the Acquisition of Formalized Knowledge in Pathology

A tool is introduced for the acquisition of pathology knowledge in a formalized form, directly by the expert. Formalization of the knowledge is intended to make descriptive pathology knowledge more suitable for computerized diagnostic support since a formal representation of knowledge allows more extensive indexing, hence more flexible access. The knowledge acquisition (KA) tool also provides a useful research instrument to investigate to what extent pathology knowledge can be made explicit, to what degree ambiguity is present, in what way experts differ when formalizing knowledge, and whether it is feasible to incrementally acquire decision criteria on the basis of the formalized descriptive knowledge.

Crucial in the design of the KA tool is the incorporated meta-knowledge, which is reflected by the knowledge-base structure and is used to elicit knowledge from the expert. Knowledge is acquired from the expert via a menu-driven user interface, which follows the general steps of the pathologist when describing a case. The paper discusses the considerations underlying the design, the implementation of the KA tool, and the research goals.

Feeding styles, parenting styles and snacking behaviour in children attending primary schools in multiethnic neighbourhoods: a cross-sectional study

OBJECTIVE

The aim of the present study was to investigate whether feeding styles and parenting styles are associated with children's unhealthy snacking behaviour and whether the associations differ according to children's ethnic background.

METHOD

Cross-sectional data from the population-based 'Water Campaign' study were used. Parents (n=644) of primary school children (6-13 years) completed a questionnaire covering sociodemographic characteristics, feeding style dimensions ('control over eating', 'emotional feeding', 'encouragement to eat' and 'instrumental feeding'), parenting style dimensions ('involvement' and 'strictness') and children's unhealthy snacking behaviour. Logistic regression analyses were performed to determine whether feeding styles and parenting styles were associated with children's unhealthy snacking behaviour.

RESULT

Overall, children whose parents had a higher extent of 'control over eating' had a lower odds of eating unhealthy snacks more than once per day (OR, 0.57; 95% CI 0.42 to 0.76). Further stratified analysis showed that 'control over eating' was associated with less unhealthy snacking behaviour only in children with a Dutch (OR, 0.37; 95% CI 0.20 to 0.68) or a Moroccan/Turkish (OR, 0.44; 95% CI 0.25 to 0.77) ethnic background. 'Encouragement to eat' was associated with a lower odds of eating unhealthy snacks every day in children with a Dutch ethnic background only (OR, 0.48; 95% CI 0.25 to 0.90). 'Instrumental feeding' was associated with a higher odds of eating unhealthy snacks more than once a day in children with a Moroccan/Turkish ethnic background only (OR, 1.43; 95% CI 1.01 to 2.04).

CONCLUSION

Our results suggest that 'control over eating' may be associated with less unhealthy snack consumption in children. The associations of feeding styles and parenting styles with children's unhealthy snacking behaviour differed between children with different ethnic backgrounds.

Children's sugar-sweetened beverages consumption: associations with family and home-related factors, differences within ethnic groups explored

Background

The consumption of sugar-sweetened beverages (SSB) may contribute to the development of overweight among children. The present study aimed to evaluate associations between family and home-related factors and children’s SSB consumption. We explored associations within ethnic background of the child.

Methods

Cross-sectional data from the population-based ‘Water Campaign’ study were used. Parents (n = 644) of primary school children (6-13 years) completed a questionnaire on socio-demographic characteristics, family and home-related factors and child’s SSB intake. The family and home-related factors under study were: cognitive variables (e.g. parental attitude, subjective norm), environmental variables (e.g. availability of SSB, parenting practices), and habitual variables (e.g. habit strength, taste preference). Regression analyses were used to evaluate the associations between family and home-related factors and child’s SSB intake (p < 0.05).

Results

Mean age of the children was 9.4 years (SD: 1.8) and 54.1% were girls. The child’s average SSB intake was 0.9 litres (SD: 0.6) per day. Child’s age, parents’ subjective norm, parenting practices, and parental modelling were positively associated with the child’s SSB intake. The availability of SSB at home and school and parental attitude were negatively associated with the child’s SSB intake. The associations under study differed according to the child’s ethnic background, with the explained variance of the full models ranging from 8.7% for children from Moroccan or Turkish ethnic background to 44.4% for children with Dutch ethnic background.

Conclusions

Our results provide support for interventions targeting children’s SSB intake focussing on the identified family and home-related factors, with active participation of parents. Also, the relationships between these factors and the child’s SSB intake differed for children with distinct ethnic backgrounds. Therefore, we would recommend to tailor interventions taking into account the ethnic background of the family.

A setup for synchrotron-radiation-induced total reflection X-ray fluorescence and X-ray absorption near-edge structure recently commissioned at BESSY II BAMline

An automatic sample changer chamber for total reflection X-ray fluorescence (TXRF) and X-ray absorption near-edge structure (XANES) analysis in TXRF geometry was successfully set up at the BAMline at BESSY II. TXRF and TXRF-XANES are valuable tools for elemental determination and speciation, especially where sample amounts are limited (<1 mg) and concentrations are low (ng ml(-1) to µg ml(-1)). TXRF requires a well defined geometry regarding the reflecting surface of a sample carrier and the synchrotron beam. The newly installed chamber allows for reliable sample positioning, remote sample changing and evacuation of the fluorescence beam path. The chamber was successfully used showing accurate determination of elemental amounts in the certified reference material NIST water 1640. Low limits of detection of less than 100 fg absolute (10 pg ml(-1)) for Ni were found. TXRF-XANES on different Re species was applied. An unknown species of Re was found to be Re in the +7 oxidation state.

Do children report differently from their parents and from observed data? Cross-sectional data on fruit, water, sugar-sweetened beverages and break-time foods

Background

Reliable assessment of children’s dietary behaviour is needed for research purposes. The aim of this study was (1) to investigate the level of agreement between observed and child-reported break-time food items; and (2) to investigate the level of agreement between children’s reports and those of their parents regarding children’s overall consumption of fruit, water and sugar-sweetened beverages (SSB).

Methods

The children in this study were 9–13 years old, attending primary schools in Rotterdam, the Netherlands. Children were observed with respect to foods brought for break-time at school. At the same day, children completed a questionnaire in which they were asked to recall the food(s) they brought to school to consume during break-time. Only paired data (observed and child-reported) were included in the analyses (n = 407 pairs). To determine each child’s daily consumption and average amounts of fruit, water and SSB consumed, children and their parents completed parallel questionnaires. Only paired data (parent-reported and child-reported) were included in the analyses (n = 275 pairs). The main statistical measures were level of agreement between break-time foods, fruit, water and SSB; and Intra-class Correlation Coefficients (ICC).

Results

More children reported bringing sandwiches and snacks for break-time than was observed (73 % vs 51 % observed and 84 % vs 33 % observed). The overall agreement between observed and child-reported break-time foods was poor to fair, with ICC range 0.16–0.39 (p < 0.05). Children reported higher average amounts of SSB consumed than did their parents (1.3 vs 0.9 L SSB, p < 0.001). Child and parent estimations of the child’s water and fruit consumption were similar. ICC between parent and child reports was poor to good (range 0.22–0.62, p < 0.05).

Conclusion

Children report higher on amount of break-time foods as compared to observations and children’s reports of SSB consumption are higher than those of their parents. Since the level of agreement between the observed break-time foods and that reported by children and the agreement of child’s intake between parent and child reports are relatively weak, future studies should focus on improving methods of evaluating children’s consumption behaviour or on ways on how to best use and interpret multiple-source dietary intake data.

PROP taster status, food preferences and consumption of high-calorie snacks and sweet beverages among 6-year-old ethnically diverse children

A healthy diet is important for optimal growth and development in children. Food preferences are a main determinant of children's intake. The aim of this study was to examine the associations of 6-n-propylthiouracil (PROP) taster status (taste sensitivity to PROP) with children's food preferences and consumption of high-calorie snacks and sweet beverages among ethnically diverse children. We analysed data from 5585 6-year-old children enrolled in the Generation R Study, a birth cohort study in Rotterdam, the Netherlands. PROP taster status was evaluated using a suprathreshold screening solution. Food preferences of the children were assessed by a two-stage protocol using photographs of eight food items (candy, chocolate, mayonnaise, whipped cream, soup, potato chips, carrot and bread), yielding both hedonic ratings (1-3) and rank order scores (1-8). Univariate and multivariable linear and logistic regression analyses were performed, using tasters as the reference group. Non-tasters had a slightly higher preference for carrots (β: -0.07; 95% CI: -0.13, -0.02 and β: -0.15; 95% CI: -0.27, -0.02 for hedonic ratings and rank order scores, respectively) and bread (hedonic ratings; β: -0.06; 95% CI: -0.11, -0.01) compared with tasters. No differences were found in children's preference for sweet, fat or salty food items. Furthermore, there were no associations of PROP taster status with the consumption of high-calorie snacks ≥ 2 times/day (aOR: 1.06; 95% CI: 0.91,1.24) or sweet beverages ≥ 3 glasses/day (aOR: 1.06; 95% CI: 0.92,1.23). Other factors relating to the family food environment may be more important for young children's food preferences and consumption of high-calorie snacks and sweet beverages than their innate taste sensitivity.

Social Inequalities in Young Children's Meal Skipping Behaviors: The Generation R Study

Background

Regular meal consumption is considered an important aspect of a healthy diet. While ample evidence shows social inequalities in breakfast skipping among adolescents, little is known about social inequalities in breakfast skipping and skipping of other meals among young school-aged children. Such information is crucial in targeting interventions aimed to promote a healthy diet in children.

Methods

We examined data from 4704 ethnically diverse children participating in the Generation R Study, a population-based prospective cohort study in Rotterdam, the Netherlands. Information on family socioeconomic position (SEP), ethnic background, and meal skipping behaviors was assessed by parent-reported questionnaire when the child was 6 years old. Multiple logistic regression analyses were performed to assess the associations of family SEP (educational level, household income, employment status, family composition) and ethnic background with meal skipping behaviors, using high SEP children and native Dutch children as reference groups.

Results

Meal skipping prevalence ranged from 3% (dinner) to 11% (lunch). The prevalence of meal skipping was higher among low SEP children and ethnic minority children. Maternal educational level was independently associated with breakfast skipping ([low maternal educational level] OR: 2.21; 95% CI: 1.24,3.94). Paternal educational level was independently associated with lunch skipping ([low paternal educational level] OR: 1.53; 95% CI: 1.06,2.20) and dinner skipping ([mid-high paternal educational level] OR: 0.39; 95% CI: 0.20,0.76). Household income was independently associated with breakfast skipping ([low income] OR: 2.43, 95% CI: 1.40,4.22) and dinner skipping ([low income] OR: 2.44; 95% CI: 1.22,4.91). In general, ethnic minority children were more likely to skip breakfast, lunch, and dinner compared with native Dutch children. Adjustment for family SEP attenuated the associations of ethnic minority background with meal skipping behaviors considerably.

Conclusion

Low SEP children and ethnic minority children are at an increased risk of breakfast, lunch, and dinner skipping compared with high SEP children and native Dutch children, respectively. Given these inequalities, interventions aimed to promote regular meal consumption, breakfast consumption in particular, should target children from low socioeconomic groups and ethnic minority children. More qualitative research to investigate the pathways underlying social inequalities in children’s meal skipping behaviors is warranted.

Food Safety Hazards and Microbiological Zoonoses in European Meat Imports Detected in Border Inspection in the Period 2008-2013

Microbiological contaminations and other food safety hazards are omnipresent within the European Union (EU) and a considerable risk for consumers, particularly in imported meat and meat products. The number of rejections at external EU borders has been increasing in recent years. Official authorities in each member state are therefore obliged to notify border rejections of food and animal feed due to a direct or indirect risk to human or animal health. This study explored the trends and temporal and spatial distribution of notifications on food safety hazards between January 2008 and December 2013 with a special emphasis on microbiological zoonoses in meat and meat products including poultry at border checks resulting from the rapid alert system for food and feed (RASFF). Results indicated that border rejection notifications are increasing exponentially, frequently due to Salmonella in poultry and shiga-toxin-producing E. coli in meat and meat products.

[Gap between the use of and need for youth care: research in Rotterdam neighbourhoods]

OBJECTIVE

To determine the relationship between the need for care and the use of care in the youth care system at neighbourhood level and the relationship with population characteristics, with consideration of the decentralisation of youth care.

DESIGN

Descriptive, retrospective study.

METHOD

Data on youth care use, indicators of need for care and population characteristics were gathered from monitors and the records of the municipality, institutions and health insurance companies. Data were grouped on a neighbourhood level (n = 49). For the analyses we used univariate and multivariate regression. We used these to distinguish between neighbourhoods with large and small gaps between youth care use and need for youth care. Differences between these neighbourhoods were analysed with t-tests.

RESULTS

A multivariate model showed that the percentage of youths with emotional problems and behavioural problems and the percentage of parents with self-reported need for care were not predictors of youth care use at a neighbourhood level. About two thirds of the variance in youth care use between neighbourhoods could be explained by the population characteristics of a neighbourhood, particularly the percentage of youths originally from non-western countries, the percentage of youths with a low level of education or special training and the percentage of people who received income support. The number of 12-18-year-olds in a neighbourhood was a predictor of youth mental health care, and the percentage of youths in a single-parent family was a predictor of out-patient youth and parenting support. Neighbourhoods with a large gap between the need for and use of youth care were socially more disadvantaged than neighbourhoods with a smaller gap.

CONCLUSION

Population characteristics explain the rate of use of youth care better than the need for youth care in a neighbourhood as measured by municipal monitors. The possible gap between the use of and need for youth care on an individual level in neighbourhoods with many characteristics of disadvantage is an important focus point for future neighbourhood teams.

Social inequalities in young children's sports participation and outdoor play

Background

Research on social inequalities in sports participation and unstructured physical activity among young children is scarce. This study aimed to assess the associations of family socioeconomic position (SEP) and ethnic background with children’s sports participation and outdoor play.

Methods

We analyzed data from 4726 ethnically diverse 6-year-old children participating in the Generation R Study. Variables were assessed by parent-reported questionnaires when the child was 6 years old. Low level of outdoor play was defined as outdoor play <1 hour per day. Series of multiple logistic regression analyses were performed to assess associations of family SEP and ethnic background with children’s sports participation and outdoor play.

Results

Socioeconomic inequalities in children’s sports participation were found when using maternal educational level (p < 0.05), paternal educational level (p < 0.05), maternal employment status (p < 0.05), and household income (p < 0.05) as family SEP indicator (less sports participation among low SEP children). Socioeconomic inequalities in children’s outdoor play were found when using household income only (p < 0.05) (more often outdoor play <1 hour per day among children from low income household). All ethnic minority children were significantly more likely to not to participate in sports and play outdoor <1 hour per day compared with native Dutch children. Adjustment for family SEP attenuated associations considerably, especially with respect to sports participation.

Conclusion

Low SEP children and ethnic minority children are more likely not to participate in sports and more likely to display low levels of outdoor play compared with high SEP children and native Dutch children, respectively. In order to design effective interventions, further research, including qualitative studies, is needed to explore more in detail the pathways relating family SEP and ethnic background to children’s sports participation and outdoor play.

Teacher and peer reports of overweight and bullying among young primary school children

BACKGROUND

Overweight is a potential risk factor for peer victimization in late childhood and adolescence. The current study investigated the association between BMI in early primary school and different bullying involvement roles (uninvolved, bully, victim, and bully-victim) as reported by teachers and children themselves.

METHODS

In a population-based study in the Netherlands, measured BMI and teacher-reported bullying behavior were available for 4364 children (mean age = 6.2 years). In a subsample of 1327 children, a peer nomination method was used to obtain child reports of bullying.

RESULTS

In both teacher- and child-reported data, a higher BMI was associated with more victimization and more bullying perpetration. For instance, a 1-point increase in BMI was associated with a 0.05 increase on the standardized teacher-reported victimization score (95% confidence interval, 0.03 to 0.07; P < .001). Combining the victimization and bullying scores into different types of bullying involvement showed that children with obesity, but not children with overweight, had a significantly higher risk to be a bully-victim (odds ratio = 2.25; 95% confidence interval, 1.62 to 3.14) than normal-weight peers.

CONCLUSIONS

At school entry, a high BMI is a risk factor associated with victimization and bullying perpetration, with obese children particularly likely to be victims and aggressors. Results were consistent for teacher and child reports of bullying, supporting the validity of our findings. Possibly, obesity triggers peer problems, but the association may also reflect a common underlying cause that makes obese children vulnerable to bullying involvement.

Sedentary behaviors, physical activity behaviors, and body fat in 6-year-old children: the generation R study

Background

Childhood overweight and obesity is a major public health concern. Knowledge on modifiable risk factors is needed to design effective intervention programs. This study aimed to assess associations of children’s sedentary behaviors (television viewing and computer game use) and physical activity behaviors (sports participation, outdoor play, and active transport to/from school) with three indicators of body fat, i.e., percent fat mass, body mass index (BMI) standard deviation scores, and weight status (normal weight, overweight).

Methods

Cross-sectional data from 5913 6-year-old ethnically diverse children were analyzed. Children’s weight and height were objectively measured and converted to BMI. Weight status was defined according to age- and sex-specific cut-off points of the International Obesity Task Force. BMI standard deviation scores were created, based on Dutch reference growth curves. Fat mass was measured my dual-energy X-ray absorptiometry (DXA). Sedentary and physical activity behaviors were assessed by parent-reported questionnaires. Series of logistic and linear regression analyses were performed, controlling for confounders (i.e., socio-demographic factors, family lifestyle factors, and other sedentary behaviors and physical activity behaviors).

Results

Sports participation was inversely associated with fat mass (p < 0.001), even after adjustment for socio-demographic factors, family lifestyle factors, and other sedentary behaviors and physical activity behaviors. No other independent associations were observed.

Conclusions

The results of this study indicate that sports participation is inversely associated with percent body fat among ethnically diverse 6-year-old children. More research in varied populations including objective measurements and longitudinal designs are needed to confirm these current results.

Effects of an intervention aimed at reducing the intake of sugar-sweetened beverages in primary school children: a controlled trial

BACKGROUND

Since sugar-sweetened beverages (SSB) may contribute to the development of overweight in children, effective interventions to reduce their consumption are needed. Here we evaluated the effect of a combined school- and community-based intervention aimed at reducing children's SSB consumption by promoting the intake of water. Favourable intervention effects on children's SSB consumption were hypothesized.

METHODS

In 2011-2012, a controlled trial was conducted among four primary schools, comprising 1288 children aged 6-12 years who lived in multi-ethnic, socially deprived neighbourhoods in Rotterdam, the Netherlands. Intervention schools adopted the 'water campaign', an intervention developed using social marketing. Control schools continued with their regular health promotion programme. Primary outcome was children's SSB consumption, measured using parent and child questionnaires and through observations at school, both at baseline and after one year of intervention.

RESULTS

Significant positive intervention effects were found for average SSB consumption (B -0.19 litres, 95% CI -0.28;-0.10; parent report), average SSB servings (B -0.54 servings, 95% CI -0.82;-0.26; parent report) and bringing SSB to school (OR 0.51, 95% CI 0.36;0.72; observation report).

CONCLUSIONS

This study supports the effectiveness of the water campaign intervention in reducing children's SSB consumption. Further studies are needed to replicate our findings.

Ethnic differences in problem perception and perceived need as determinants of referral in young children with problem behaviour

An underrepresentation of ethnic minority children in mental health care settings is consistently reported. Parents of ethnic minority children are, however, less likely to perceive problem behaviour in their children. Our hypothesis was that, as a result of ethnic differences in problem perception, referral to care by a child health professional (CHP) would be lower for 5- to 6-year-old (high-risk) children from ethnic minority backgrounds than for their peers from the ethnic majority (Dutch origin). For 10,951 children in grade two of elementary school, parents and/or teachers completed the Strengths and Difficulties Questionnaire (SDQ) as well as questions on problem perception (PP) and perceived need for professional care (PN). Referral information was obtained from the Electronic Child Records (ECR) for 1,034 of these children. These children had a high (>90th percentile) SDQ score, and were not receiving mental health care. CHP's referred 144 children (14 %) during the routine health assessments. A lower problem perception was reported by parents of ethnic minority children (40-72 %) than by parents of the ethnic majority group (80 %; p < 0.001), but there were no ethnic differences in referral (OR range 0.9-1.9-p > 0.05). No ethnic differences were found for parental PN, nor for teacher's PP or PN. Despite a lower problem perception in ethnic minority parents when compared to ethnic majority parents, no ethnic differences were found in referral of children with problem behaviour in a preventive health care setting.

Ethnicity, socioeconomic position and severity of problems as predictors of mental health care use in 5- to 8-year-old children with problem behaviour

BACKGROUND

Empirical research on mental health care use and its determinants in young school-aged children is still scarce. In this study, we investigated the role of ethnicity, socioeconomic position (SEP) and perceived severity by both parents and teachers on mental health care use in 5- to 8-year old children with emotional and/or behavioural problems.

METHODS

Data from 1,269 children with a high score([P90) on the Strengths and Difficulties Questionnaire (SDQ) in the school year 2008–2009 were linked to psychiatric case register data over the years 2010–2011. Cox proportional hazards models were used to predict mental health care use from ethnicity, SEP and perceived severity of the child's problems.

RESULTS

During the follow-up period, 117 children with high SDQ scores (9.2 %) had used mental health care for the first time. Ethnic minority children were less likely to receive care than Dutch children (HR Moroccan/Turkish:0.26; 95 % CI 0.13-0.54, HR other ethnicity: 0.26; 95 %CI 0.12-0.58). No socioeconomic differences were found.After correction for previous care use, ethnicity and parental perceived severity, impact score as reported by teachers was significantly associated with mental healthcare use (HR 1.58; 95 % CI 1.01–2.46).

CONCLUSIONS

Ethnicity is an important predictor of mental health care use in young children. Already in the youngest school-aged children, ethnic differences in the use of mental health care are present.A distinct predictor of care use in this age group is severity of emotional and behavioural problems as perceived by teachers. Therefore, teachers may be especially helpful in the process of identifying young children who need specialist mental health care.

Maternal educational level and preschool children's consumption of high-calorie snacks and sugar-containing beverages: mediation by the family food environment

OBJECTIVE

To examine the associations between maternal educational level and preschoolers' consumption of high-calorie snacks and sugar-containing beverages, and to assess the mediating effects of variables relating to the family food environment.

METHODS

We analyzed data from 2814 native Dutch preschoolers enrolled in a birth cohort study in Rotterdam (the Netherlands), between 2002 and 2006. Logistic regression models were used to calculate odds ratios of snacking ≥ 2 times/day and consuming sugar-containing beverages ≥ 3 glasses/day for children of mothers with low, mid-low, and mid-high educational levels (reference group: high educational level), before and after adjustment for mediators.

RESULTS

Children of low and mid-low educated mothers were significantly more likely to consume excessive amounts of high-calorie snacks and sugar-containing beverages compared with children of high educated mothers, with the highest odds in children of low educated mothers (OR: 2.44; 95% CI: 1.84, 3.23 and OR: 2.46; 95% CI: 1.87, 3.24 respectively). Parental feeding practices, parental consumption of sugar-containing beverages, and children's television time partly explained these associations.

CONCLUSION

Maternal educational level is inversely related to preschoolers' consumption of high-calorie snacks and sugar-containing beverages. Targeting the family food environment may be an effective way of reducing educational inequalities in children's unhealthy dietary behaviors.

Correlates of physical activity in 2-year-old toddlers: the generation R study

OBJECTIVE

To describe and identify correlates of objectively measured physical activity and sedentary behavior in 2-year-old toddlers.

STUDY DESIGN

A total of 347 children participating in a birth cohort study wore a unaxial ActiGraph accelerometer during 1 weekday and 1 weekend day. Information on potential correlates was assessed by parent-reported questionnaires, delivery reports, and regular visits to child health centers. Univariate and multivariable linear regression analyses were conducted to examine the associations between potential correlates and the following physical activity outcomes: percentage of time spent in sedentary behavior, percentage of time spent in moderate-to-vigorous physical activity, and mean counts per minute.

RESULTS

A high percentage of monitored time was spent in sedentary behavior; 85.6% on weekdays and 84.5% on weekend days. Four correlates were significantly associated with at least 1 physical activity outcome in the multivariable regression models: child's sex, child's age, number of siblings, and season of measurement. The associations of gross motor development with moderate-to-vigorous physical activity and mean counts per minute approached significance. Associations of socioeconomic variables and child's body mass index z-score with physical activity outcomes were not significant.

CONCLUSION

Two-year-old toddlers spend most of their time in sedentary behavior. No modifiable correlates were identified. Further research on physical activity and associated health benefits among very young children is warranted.
