Ethnic differences and parental beliefs are important for overweight prevention and management in children: a cross-sectional study in the Netherlands

Analyzing early childhood allergy prevention motivation of mothers of infants and its predictors using latent class analysis and structural equation modelling

BACKGROUND

Allergic diseases are among the most common chronic diseases in childhood. Early childhood allergy prevention (ECAP) behaviors of those caring for the infant during pregnancy and the first months of life may influence the risk of allergy development over the life course. Motivation and intention to use appropriate primary ECAP measures are thus of critical importance.

AIMS

To characterize parental ECAP motivation, (a) valid indicators will be developed and (b) typical parental characteristics will be identified. (c) According to socio-cognitive models, the predictive value of parental risk perception, control belief and self-efficacy for parental ECAP motivation shall be determined.

METHOD

A sample of N = 343 (expectant) mothers of infants completed a questionnaire on self-reported ECAP motivation, risk perception, control belief, and self-efficacy. The cross-sectional data were analyzed using latent class analysis and structural equation modelling including nominal regression models.

RESULTS

Four typical maternal response profiles (motivated to a customary degree, 70%; motivated to use primary preventive measures, 17.8%; reluctant towards new prevention measures, 6.4%; highly motivated to apply preventive measures in case of an existing allergy, 5.8%) could be identified for the items on ECAP motivation. After splitting the model variables "risk perception" (allergy vs. allergy-associated general health problems) and "self-efficacy" (trust vs. insecurity) a satisfactory model-fit was achieved (CFI = .939; RMSEA = .064). Particularly, increased "risk perception-allergy" (OR = 1.655) and "self-efficacy-insecurity" (OR = 2.013) as well as lower "risk perception-general health" (OR = 0.555) and "control belief" (OR = 0.217), respectively, are associated with higher ECAP motivation.

CONCLUSION

The use of ECAP-measures by parents to protect their newborns from allergies is important, but there are deficiencies in their implementation. Based on a social cognitive model approach, predictive characteristics could be identified, which are associated with increased motivation to implement ECAP-measures. For public health our findings provide a promising basis for conception of behavioral and environmental ECAP prevention measures and their motivated implementation by parents.

Cardiometabolic risk profile among children with migrant parents and role of parental education: the IDEFICS/I.Family cohort

BACKGROUND AND AIMS

Evidence shows that migrant children have a higher risk of developing obesity than those with native parents. We aimed to investigate the association between parental migration background and cardiometabolic health in children and adolescents in Europe.

METHODS AND RESULTS

We included 8745 children aged 2-17 from the second follow-up of the European IDEFICS/I.Family cohort. Linear regression models were used to investigate the association between parental migration background (one or two migrant parent(s) vs native parents) and body mass index (BMI), metabolic syndrome (MetS) score and its individual components. Outcome variables were parametrized as age and sex-specific z-scores. We adjusted for age, sex, country, and parental education, and additionally for parental income, lifestyle including dietary factors, and maternal BMI. On average, children with two migrant parents had higher z-scores of BMI (+0.24 standard deviation (SD)) and MetS score (+0.30 SD) compared to those with native parents, whereas no significant differences were seen for children with one migrant parent. Associations were attenuated when controlling for maternal BMI and sports club activity. Parental education modified the associations with BMI and MetS z-scores such that they were more pronounced in children with low parental education.

CONCLUSION

Children with two migrant parents were at higher risk for adverse cardiometabolic health compared to children with native parents, especially in families with low parental education. These associations were explained by lower physical activity and maternal body weight and encourages early intervention strategies by schools and communities.

Systematic review of the correlates of outdoor play and time among children aged 3-12 years

BACKGROUND

Due to the myriad of benefits of children's outdoor play and time, there is increasing concern over its decline. This systematic review synthesized evidence on the correlates of outdoor play and outdoor time among children aged 3-12 years.

METHODS

A total of 12 electronic databases in five different languages (Chinese, English, Korean, Spanish, Portuguese) were searched between October 28, 2019 and July 27, 2020. Covidence software was used for screening and Microsoft Excel with a predesigned coding form was used for data extraction. Evidence was synthesized and correlates were categorized using the socioecological model framework.

RESULTS

Based on 107 studies representing 188,498 participants and 422 childcare centers from 29 countries, 85 studies examined potential correlates of outdoor play while 23 studies examined that of outdoor time (one examined both). The duration of outdoor play and outdoor time ranged between 60 and 165 min/d and 42-240 min/d, respectively. Out of 287 (outdoor play) and 61 (outdoor time) potential correlates examined, 111 correlates for outdoor play and 33 correlates for outdoor time were identified as significant correlates. Thirty-three variables were identified as key/common correlates of outdoor play/time, including eight correlates at the individual level (e.g., sex/gender, race/ethnicity, physical activity), 10 correlates at the parental level (e.g., parental attitude/support/behavior, parenting practice), nine at the microsystem level (e.g., proximal home/social environment such as residence type, peer influence), three at the macrosystem/community level (e.g., availability of space children can play), and three at the physical ecology/pressure for macrosystem change level (e.g., seasonality, rurality). No key correlates were found at the institutional level.

CONCLUSIONS

Individual, parental, and proximal physical (home) and social environments appear to play a role in children's outdoor play and time. Ecological factors (i.e., seasonality, rurality) also appear to be related to outdoor play/time. Evidence was either inconsistent or lacking at institutional and macrosystem/community levels. Standardizing terminology and measures of outdoor play/time is warranted. Future work should investigate the interactions and processes of multiple variables across different levels of socioecological modelling to better understand the mechanisms through which outdoor play/time opportunities can be optimized for children while paying special attention to varying conditions in which children are born, live, and play.

Healthcare utilisation in overweight and obese children: a systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis aims to systematically analyse the association of overweight and obesity with health service utilisation during childhood.

DATA SOURCES

PubMed, MEDLINE, CINAHL, EMBASE and Web of Science.

METHODS

Observational studies published up to May 2020 that assessed the impact of overweight and obesity on healthcare utilisation in children and adolescents were included. Studies were eligible for inclusion if the included participants were ≤19 years of age. Findings from all included studies were summarised narratively. In addition, rate ratios (RRs) and 95% CIs were calculated in a meta-analysis on a subgroup of eligible studies.

OUTCOME MEASURES

Included studies reported association of weight status with healthcare utilisation measures of outpatient visits, emergency department (ED) visits, general practitioner visits, hospital admissions and hospital length of stay.

RESULTS

Thirty-three studies were included in the review. When synthesising the findings from all studies narratively, obesity and overweight were found to be positively associated with increased healthcare utilisation in children for all the outcome measures. Six studies reported sufficient data to meta-analyse association of weight with outpatient visits. Five studies were included in a separate meta-analysis for the outcome measure of ED visits. In comparison with normal-weight children, rates of ED (RR 1.34, 95% CI 1.07 to 1.68) and outpatient visits (RR 1.11, 95% CI 1.02 to 1.20) were significantly higher in obese children. The rates of ED and outpatient visits by overweight children were only slightly higher and non-significant compared with normal-weight children.

CONCLUSIONS

Obesity in children is associated with increased healthcare utilisation. Future research should assess the impact of ethnicity and obesity-associated health conditions on increased healthcare utilisation in children with overweight and obesity.

Effect of neighbourhood socioeconomic status on overweight and obesity in children 2-15 years of different ethnic groups

BACKGROUND

Studies on the influence of neighbourhood socioeconomic status (N-SES) on overweight and obesity rates in children from different ethnic backgrounds are scarce. This study investigated the differential effect of N-SES on overweight (including obesity) and obesity prevalence in different ethnic groups, and if N-SES explains ethnic differences in the prevalence of overweight and obesity.

DESIGN

A population based study of 109 766 body mass index (BMI) measurements of 86 209 children 2-15 years of Dutch, Turkish, Moroccan and South Asian descent. BMI class was determined with The International Obesity Task Force, and South Asian specific BMI cut-offs. WHO BMI criteria were applied for reference purposes. The effect of N-SES on prevalence rates was studied with generalized linear mixed models.

RESULTS

Neighbourhood SES was negatively associated with overweight and obesity. However, the effect of N-SES on overweight was stronger in Dutch children (OR 0.75, 95% CI 0.73-0.77) than in Turkish (OR 0.86, 95% CI 0.82-0.90), Moroccan (OR 0.91, 95% CI 0.86-0.97) and South Asian (OR 0.90, 95% CI 0.84-0.96) children. The influence of N-SES on obesity showed a similar pattern, except for Moroccan children in whom obesity prevalence remained stable over the whole N-SES range. At the same N-SES, overweight and obesity prevalence was significantly higher in Turkish, Moroccan and especially South Asian children compared with Dutch children. Adjusting for N-SES attenuated the ethnic differences.

CONCLUSIONS

Neighbourhood SES was negatively associated with overweight and obesity rates in all ethnic groups, but only partly explained the ethnic differences in overweight and obesity prevalence.

Migration background and childhood overweight in the Hannover Region in 2010-2014: a population-based secondary data analysis of school entry examinations

Overweight and obesity constitute a global epidemic with rates that are increasing rapidly in children. The aim of the present study was to examine ethnic differences in the prevalence of overweight in pre-school children in a multicultural context. Data were collected from a compulsory school entry examination in the Hannover Region, Germany (n = 50,716) from 2010 to 2014. The prevalence of overweight (including pre-obesity and obesity status) and obesity was estimated using a German national reference. The migration status of the children was based on the parent's migration history. Multivariable logistic and hierarchical multinomial regression analyses were performed to identify factors associated with the overweight, pre-obesity, and obesity status. The prevalence of overweight was significantly higher among migrant children (12.7%) than among the non-migrant children (6.9%). After adjusting for socioeconomic and child development variables, migration background was strongly associated with weight status. The Turkish migrant children showed the highest odds of being pre-obesity (OR 2.05, 95%CI 1.7-2.56) and obesity (OR 2.09, 95%CI 1.67-2.77) compared to non-migrant children.

CONCLUSION

Ethnic and social inequalities exist in childhood overweight among pre-school children in the Hannover Region. Thus, appropriate interventions targeting high-risk migrant groups are needed. What is Known: • The current trend of prevalence rates in Germany for overweight and obesity of pre-school children is becoming stable. • Prevalence of overweight and obesity is clearly higher among migrant children than among non-migrant children. What is New: • This article reveals ethnic variance among different migrant groups. • Turkish migrant children have a higher rate of prevalence even compared to other migrant groups. • Length of child day care attendance fails to exert a strong influence on overweight after adjusting for socio-economic and child development variables.

Personalized Web-Based Advice in Combination With Well-Child Visits to Prevent Overweight in Young Children: Cluster Randomized Controlled Trial

BACKGROUND

Overweight is a major health issue, and parent-targeted interventions to promote healthy development in children are needed.

OBJECTIVE

The study aimed to evaluate E-health4Uth Healthy Toddler, an intervention that educates parents of children aged 18 to 24 months regarding health-related behaviors, as compared with usual care. The effect of this intervention on the following primary outcomes was evaluated when the children were 36 months of age: health-related behaviors (breakfast daily, activity and outside play, sweetened beverage consumption, television (TV) viewing and computer time), body mass index (BMI), and the prevalence of overweight and obesity.

METHODS

The BeeBOFT (acronym for breastfeeding, breakfast daily, outside playing, few sweet drinks, less TV viewing) study is a cluster randomized controlled trial involving 51 Youth Health Care (YHC) teams. In total, 1094 parents participated in the control group, and 1008 parents participated in the E-health4Uth Healthy Toddler intervention group. The intervention consisted of Web-based personalized advice given to parents who completed an eHealth module and discussion of the advice during a regular well-child visit. In this study the eHealth module was offered to parents before two regular well-child visits at 18 and 24 months of age. During the well-child visits, the parents' personalized advice was combined with face-to-face counseling provided by the YHC professional. Parents in the control group received usual care, consisting of the regular well-child visits during which general information on child health-related behavior was provided to parents. Parents completed questionnaires regarding family characteristics and health-related behaviors when the child was 1 month (inclusion), 6 months, 14 months, and 36 months (follow-up) of age. The child's height and weight were measured by trained health care professionals from birth through 36 months of age at fixed time points. Multilevel linear and logistic regression models were used to evaluate the primary outcomes at 36 months of age.

RESULTS

At 36 months, we observed no differences between health-related behaviors of children, BMI or the percentage of children having overweight or obesity in the control and intervention group (P>.05). An analysis of the intervention effect revealed that boys benefited from eating breakfast daily, non-Dutch children spent more time being active or playing outdoors, children of low-educated parents and of overweight and obese mothers spent less time watching TV or using the computer, and children of normal weight mothers drank less sweetened beverages (P<.05) compared with the control group.

CONCLUSIONS

The E-health4Uth Healthy Toddler intervention resulted in small improvements in health-related behaviors among subgroups but had no significant effects with respect to the children's BMI. We conclude that the E-health4Uth Healthy Toddler intervention may be useful for pediatric health care professionals in terms of providing parents with personalized information regarding their child's health-related behaviors.

Call for early prevention: prevalence rates of overweight among Turkish and Moroccan children in The Netherlands

BACKGROUND

Monitoring overweight in risk groups is necessary. Our aim is to assess the trend in overweight and obesity in Turkish and Moroccan children in the Netherlands since 1997 and to monitor the levels of lifestyle-related behaviours in 2009.

METHODS

We selected cross-sectional data of Turkish and Moroccan children aged 2-18 years from two national Growth Studies performed in 1997 and 2009 in the Netherlands. Lifestyle-related behaviours were obtained in the 2009 study by questionnaire.

RESULTS

In 2009, 31.9% of Turkish and 26.6% of Moroccan children had overweight, whereas this was, respectively, 26.7% and 19.6% in 1997. Already at 2 years, 21.1% in Turkish and 22.7% in Moroccan children had overweight in 2009. The prevalence of obesity was above 4% from 3 years onwards. High (i.e. ≥ 25%) prevalence rates of unhealthy lifestyle-related behaviours were found for not having breakfast (26-49%) among Turkish and Moroccan adolescent (i.e. 15-18 years) girls, consuming no fruit (29-45%) and watching TV/PC ≥ 2 h (35-72%) among all Turkish and Moroccan adolescents, no walking/cycling to school/day care among preschool children (2-4 years) (28-56%) and adolescents (34-94%), drinking ≥ 2 glasses of sweet beverages (44-74%) and being <1 h physically active (29-65%) among all children.

CONCLUSION

An upward trend of overweight and obesity occurred in Turkish and Moroccan children. Already at 2 years of age, one out of five Turkish and Moroccan children had overweight, which calls for early prevention with attention to specific lifestyle-related behaviours.

Sleep duration differences between children of migrant and native origins

Aim

To explore whether primary school children of migrant and native Dutch origins differ regarding their sleep duration per night, a risk for overweight and obesity, and to determine to what degree differences in parenting styles contribute to these differences.

Subjects and methods

A cross-sectional survey, including 1,943 children aged 8-9 years old and their primary caregivers, was performed. Data were collected from primary schools in cities and adjacent municipalities in The Netherlands: Eindhoven and Rotterdam. The outcome measure was mean sleep duration per night. The main independent variable was migrant background, based on the country of birth of the parents. A possible mediating variable was parenting style (rejecting, neglecting, permissive, authoritarian, authoritative). Age and sex of the child as well as parental socioeconomic status, as indicated by educational level, were added as confounders.

Results

Dutch children have the highest sleep duration: more than 11 h (mean = 670.1; SD = 27.7). All migrant children show less than 11 h of sleep per night. Migrant children of non-Western origin, especially Turkish and Moroccan children, show the lowest sleep duration per night. Parenting styles do not contribute to these differences.

Conclusion

Migrant background is associated with sleep duration. As children of migrant origin are, in general, at higher risk for overweight and obesity and sleep duration is regarded as a risk factor for overweight and obesity, further investigation of this association is needed.

Childhood Overweight Dependence on Mother-Child Relationship

The causes of childhood overweight are numerous and inter-related. The mother-child relationship is of great significance for the child's health. Previous studies have found patterns of dysfunctional interaction in families with obese children. Therefore, development of childhood overweight could be due to the mother-child relationship. The aim of this study was to investigate how, and to what degree, the mother-child relationship, assessed by the mothers, was related to overweight among children aged seven to nine years. The study was a cross sectional case-controlled one. It included 111 overweight and 149 non-overweight seven to nine year old children and their mothers. Weight status was determined according to the International Obesity Task Force reference for children Body Mass Index, age and gender adjusted. An interviewer-administered questionnaire was used to categorize the mother-child relationship as: complementary, asymmetrical, symmetrical or symbiotic prototypes. There was no difference in mother-child relationships - characterized by the prototypes - between the overweight and non-overweight mother-child pairs. Therefore, we conclude that the mother-child relationship has no bearing on the child's weight status according to the prototypes. It is suggested that it is more the culture, or the universal phenomenon of expressing love through food, than the mother-child relationship, which influences the development of childhood overweight, or that the mothers are not capable of assess the true attachment style between themselves and their children.

Trends in a life threatening condition: morbid obesity in dutch, Turkish and Moroccan children in The Netherlands

BACKGROUND

Morbid obesity can be a life threatening condition. The aim of our study is to assess the trend in morbid obesity in The Netherlands among children of Dutch origin since 1980, and among children of Turkish and Moroccan origin since 1997.

METHODS AND FINDINGS

Cross-sectional height and weight data of children of Dutch, Turkish and Moroccan origin aged 2-18 years were selected from three national Dutch Growth Studies performed in 1980, 1997 and 2009 (n = 54,814). Extended international (IOTF) cut-offs in childhood were used to define morbid obesity (obesity class II and III combined). The morbidity index for overweight was calculated as the prevalence of morbid obesity divided by the prevalence of overweight. Our study showed that the prevalence of morbid obesity in children of Dutch origin was 0.59% in boys and 0.53% in girls in 2009. Significant upward trends occurred since 1980 and 1997. The prevalence was three to four fold higher in Turkish children compared to Dutch children. The Turkish children also had an upward trend since 1997, but this was only statistically significant in boys. The prevalence of morbid obesity in Moroccan children was two to three fold higher than in Dutch children, but it remained almost stable between 1997 and 2009. The Dutch and Turkish children showed an upward trend in morbidity index for overweight since respectively 1980 and 1997, while the Moroccan children showed a downward trend since 1997. In 2009, children of low educated parents had the highest prevalence rates of morbid obesity; 1.06% in Dutch, 2.11% in Turkish and 1.41% in Moroccan children.

CONCLUSIONS AND SIGNIFICANCE

An upward trend of morbid obesity in Dutch and Turkish children in The Netherlands occurred. Monitoring and reducing the prevalence of childhood morbid obesity is of high importance for these children, health care and the community.

Correlates of parental misperception of their child's weight status: the 'be active, eat right' study

Objective

This study reported on correlates of parental perception of their child’s weight status. Associations between parental misperception (i.e., underestimation of the child’s weight) and parental intention to improve their child’s overweight-related health behaviors and their child meeting guidelines regarding these behaviors were also investigated.

Methods

Baseline data from the population-based ‘Be active, eat right study’ were used. The population for analysis consisted of 630 overweight and 153 obese five year-old children and their parents. Questionnaires were used to measure parental perception of the child’s weight status, correlates of misperception (i.e., child age, child gender, child BMI, parental age, parental gender, parental country of birth, parental educational level and parental weight status), overweight-related health behaviors (i.e., child playing outside, having breakfast, drinking sweet beverages, and watching TV), and parental intention to improve these behaviors. Height and weight were measured using standardized protocols. Multivariable logistic regression analyses were performed.

Results

In total, 44.40% of the parents misperceived their child’s weight status. Parental misperception was associated with lower child BMI, the parent being the father, a foreign parental country of birth, and a lower parental education level (p<0.05). Parental misperception was not associated with parental intention to improve child overweight-related health behavior, nor with child meeting the guidelines of these behaviors.

Discussion

This study showed that almost half of the parents with an overweight or obese child misperceived their child’s weight status. A correct parental perception may be a small stepping-stone in improving the health of overweight and obese children.
