Childhood overweight/obesity and pediatric asthma: the role of parental perception of child weight status

Parents of 5-to-12-year-old children with food allergies report more frequent use of structure-based food parenting practices

Objectives

Food parenting practices (FPP) can have effects on children's eating behaviors. Over 8 million children in the US have food allergies, however, little is known about FPP for those who have children with food allergies. The objective of this study was to describe FPP among children with food allergies.

Methods

Recruited across the United States using ResearchMatch in February and March 2021, parents of children ages 5-12 years (n = 346; n = 77 with food allergies) completed a single, online survey which measured health history, demographics, and FPP. Linear regressions were used to examine associations between FPP of children with and without food allergies, and associations between food allergy factors and FPP.

Results

Parents of children with food allergies reported greater use of limit exposure than parents of children without food allergies (B = 0.131; [CI], 0.021-0.293; P = 0.024), with no differences in other types of FPP.

Conclusions

Parents of children with food allergies reported more frequent structure-based FPP than parents of children without food allergies. More work is needed to explore mechanisms that promote positive food parenting among this population.

Mediterranean-Type Diets as a Protective Factor for Asthma and Atopy

We are currently riding the second wave of the allergy epidemic, which is ongoing in affluent societies, but now also affecting developing countries. This increase in the prevalence of atopy/asthma in the Western world has coincided with a rapid improvement in living conditions and radical changes in lifestyle, suggesting that this upward trend in allergic manifestations may be associated with cultural and environmental factors. Diet is a prominent environmental exposure that has undergone major changes, with a substantial increase in the consumption of processed foods, all across the globe. On this basis, the potential effects of dietary habits on atopy and asthma have been researched rigorously, but even with a considerable body of evidence, clear associations are far from established. Many factors converge to obscure the potential relationship, including methodological, pathophysiological and cultural differences. To date, the most commonly researched, and highly promising, candidate for exerting a protective effect is the so-called Mediterranean diet (MedDi). This dietary pattern has been the subject of investigation since the mid twentieth century, and the evidence regarding its beneficial health effects is overwhelming, although data on a correlation between MedDi and the incidence and severity of asthma and atopy are inconclusive. As the prevalence of asthma appears to be lower in some Mediterranean populations, it can be speculated that the MedDi dietary pattern could indeed have a place in a preventive strategy for asthma/atopy. This is a review of the current evidence of the associations between the constituents of the MedDi and asthma/atopy, with emphasis on the pathophysiological links between MedDi and disease outcomes and the research pitfalls and methodological caveats which may hinder identification of causality. MedDi, as a dietary pattern, rather than short-term supplementation or excessive focus on single nutrient effects, may be a rational option for preventive intervention against atopy and asthma.

Caregivers' perceptions of the relationship among weight, health status, and asthma in their children

Asthma and obesity are the two most common childhood illnesses and are physiologically interrelated. Few studies have assessed parental perceptions and beliefs about this relationship to better target education and therapy. This study aimed to determine caregiver beliefs and perceptions regarding weight, health status, and asthma diagnoses. Data from a survey of caregivers to children aged 4-11 years are merged with corresponding anthropometric and medical data from the electronic medical record. Caregivers of children with asthma completed a supplemental questionnaire. Univariable and multivariable logistic regressions were used to evaluate associations between perception of health problem, asthma, and weight status. Increased weight status was ≥ 85th body mass index percentile per Centers for Disease Control classifications. Compared to caregivers of healthy children and those of children with healthy weight and asthma, caregivers of dual diagnosis children were more likely to identify weight as a health problem (OR = 3.89, 95% confidence interval [1.48, 10.21]). Nevertheless, only 31% of caregivers of children with dual diagnosis believed weight contributed to the severity of their child's asthma. Less than one third of caregivers of dual diagnosis children believed that these diagnoses are interrelated. Addressing this gap in understanding is a critical next step to developing family-centered interventions.

The association of co-morbid asthma and overweight/obese status with healthcare utilization and caregiver perception of health in children 4-17 years, a NHANES study

OBJECTIVE

Asthma and obesity are two of the most common chronic childhood illnesses. The purpose of this study was to better understand the relationship between co-morbid asthma and obesity in children aged 4-17 and whether it impacts the caregiver's perception of health and/or healthcare utilization.

METHODS

This was a secondary analysis of the National Health and Nutrition Examination Surveys (NHANES) datasets from 2007 to 2018. Cumulative logistic regression models were used to analyze the caregiver's perception of health, received healthcare, and overnight hospital stay as dependent variables. Asthma and weight status were included as covariates, with adjustment for age, income, head of the household's education, gender, race, and insurance.

RESULTS

The sample included 15,386 children. When looking at weight status in addition to asthma, compared to caregivers of children with current asthma and normal weight, caregivers of children with current asthma and with obesity are more likely to perceive their children as having worse health (OR = 1.73, 95%CI = [1.30, 2.32], p = 0.0003), and are more likely to have more frequent healthcare utilization but the results did not reach a statistical significance.

CONCLUSIONS

Caregiver's perception of overall health was worse in caregivers of those with co-morbid obesity/asthma than in caregivers of children with asthma alone. This indicates that caregivers of children with co-morbid asthma and obesity have insight into their children's condition and may be primed for discussion and counseling in the healthcare setting.

Factors Influencing Parents' and Children's Misperception of Children's Weight Status: a Systematic Review of Current Research

PURPOSE OF REVIEW

Misperception of children's weight status is prevalent among parents and children themselves and may impact parents' and children's health behaviors. This study was conducted in order to provide a descriptive systematic review of research on factors influencing parents' and children's misperceptions of children's weight status published in the past 5 years.

RECENT FINDINGS

Factors studied most often in relation to parents' and children's misperception included children's weight status, gender, and age, as well as parents' weight status, parental education levels and socioeconomic status, and ethnicity. Most determinants that were found to have a significant influence on misperception in parents also did in children. The literature on misperception of children's weight status is extensive. Most determinants assessed in included studies were known determinants of childhood obesity. Further research should be directed toward better understanding the impact of weight status perception (whether it is accurate or not) on health behaviors and weight gain over time.

A biopsychosocial approach to processes and pathways in the development of overweight and obesity in childhood: Insights from developmental theory and research

Childhood obesity has reached alarming proportions in many countries. There is consensus that both biological (especially genetic) and environmental (including psychosocial) factors contribute to weight gain and obesity in childhood. Research has identified extensive risk or predictive factors for childhood obesity from both of these domains. There is less consensus about the developmental processes or pathways showing how these risk factors lead to overweigh/obesity (OW/OB) in childhood. We outline a biopsychosocial process model of the development of OW/OB in childhood. The model and associated scholarship from developmental theory and research guide an analysis of research on OW/OB in childhood. The model incorporates biological factors such as genetic predispositions or susceptibility genes, temperament, and homeostatic and allostatic processes with the psychosocial and behavioral factors of parenting, parental feeding practices, child appetitive traits, food liking, food intakes, and energy expenditure. There is an emphasis on bidirectional and transactional processes linking child biology and behavior with psychosocial processes and environment. Insights from developmental theory and research include implications for conceptualization, measurement, research design, and possible multiple pathways to OW/OB. Understanding the developmental processes and pathways involved in childhood OW/OB should contribute to more targeted prevention and intervention strategies in childhood.

Prevention of Lifestyle-related Diseases by Utilization of Newly Developed Health Record Booklet "My Karte" in Mitoyo and Kanonji Areas

In the Mitoyo and Kanonji areas, Kagawa Prefecture, Japan, we have newly developed a simple health record booklet for parents with children called "My Karte", which is an enlarged edition of the maternal and child health handbook. Our municipality borough gives this booklet together with the maternal and child handbook to all pregnant women without exception. In this booklet, care personnel or child by themselves write down the health condition and body development of the child, including medical examination records and vaccinations. From an overview of this simple record, healthcare practitioners, caretakers or school nurses can immediately grasp the child's body condition, for example, whether the child is overweight or underweight, and various health problems early and precisely. In addition, the child and care personnel can evaluate the health condition of the child through self-assessment. We hope that the self-assessment will promote health during the child's life. Moreover we are planning to collect and analyze the data from the distributed My Karte. The analyzed results will be released to the public, which will promote health consciousness in this area and give healthcare professionals basic and important data useful for daily medical practice.

[Overweight in primary school-age children. Prevalence and risk factors]

BACKGROUND

Various studies show that pre-school age is a sensitive period for the development of overweight and obesity. During a longitudinal study between 2010 and 2013, the municipal health authority (city of Frankfurt) in cooperation with the university children's hospital investigated the development of weight in children aged 5 to 8.

MATERIALS AND METHODS

The weight and height of a collective of 5720 children were measured (2010/11). In addition, nutritional and exercise habits, as well as media consumption was documented for 4758 children through a questionnaire during the school enrolment procedure. The weight and height of 3481 children were measured again in the second grade (2012/13).

RESULTS

Over a period of 24 months, the percentage of overweight (not obese) children increased from 7.5 to 9.4 % and that of obese children from 4.5 to 5.0 %. 164 of 2818 children with a normal initial weight (5.8 %) changed to percentile class overweight or obese. 79 of 260 children who were initially overweight, not obese (30 %), changed to the group of normal weight, but only 4 out of 156 obese children (3 %). Increased TV consumption (> 1 h per day), availability of their own television, lack of physical activity, and consumption of high-calorie drinks were risk factors for the development of overweight during the primary school age. 72 % of parents of overweight children and 22 % of obese children falsely classified their children as normal weight.

CONCLUSIONS

Targeted education about the risk of obesity in the primary school age and offers for early intervention should be established in the healthcare services concerned.

Item-level informant discrepancies across obese-overweight children and their parents on the PedsQL™ 4.0 instrument: an iterative hybrid ordinal logistic regression

PURPOSE

Child obesity has become a major health concern worldwide. In order to provide successful intervention strategies, it is necessary to understand how obese-overweight children and their parents perceive obesity and its consequences on child's health-related quality of life (HRQoL). This study aimed to assess measurement equivalence of the PedsQL™ 4.0 across obese-overweight children and their parents.

METHODS

The items in the PedsQL™ 4.0 were analysed for differential item functioning (DIF) across obese-overweight children and their parents using an iterative hybrid ordinal logistic regression/item response theory approach. The sample included 647 overweight-obese children and their parents, who completed child and parent reports of the PedsQL™ 4.0, respectively.

RESULTS

Overall, 17 out of 23 (74%) items were flagged with DIF across two groups: eight items exhibited uniform DIF and nine items non-uniform DIF. In addition, parents of obese children rated the child's HRQoL significantly lower than their children in all domains of the PedsQL™ 4.0, and this finding did not change whether or not items with uniform DIF were included.

CONCLUSIONS

Although obese-overweight children and their parents interpret items of the PedsQL™ 4.0 in a conceptually different manner, removing or retaining DIF items in the subscales had no significant effects on group differences. Accordingly, it appears that observed differences in HRQoL scores across child and parent reports are a true difference and not a reflection of measurement artefact.
