Healthy for now? A cross-sectional study of the comorbidities in obese preschool children in the United States

Growth During Infancy After Extremely Preterm Birth: Associations with Later Neurodevelopmental and Health Outcomes

OBJECTIVE

To evaluate associations between changes in weight, length, and weight/length ratio during infancy and outcomes later in life among individuals born extremely preterm.

STUDY DESIGN

Among participants in the Extremely Low Gestational Age Newborn (ELGAN) study, we measured weight and length at discharge from the neonatal intensive care unit (NICU) and at age 2 years and evaluated neurocognitive, psychiatric, and health outcomes at age 10 years and 15 years. Using multivariable logistic regression, we estimated associations between gains in weight, length, and weight/length ratio z-scores between discharge and 2 years and outcomes at 10 and 15 years. High gain was defined as the top quintile of change; low gain, as the bottom quintile of change.

RESULTS

High gains in weight and weight/length were associated with greater odds of obesity at 10 years, but not at 15 years. These associations were found only for females. High gain in length z-score was associated with lower odds of obesity at 15 years. The only association found between high gains in growth measures and more favorable neurocognitive or psychiatric outcomes was between high gain in weight/length and lower odds of cognitive impairment at age 10 years.

CONCLUSIONS

During the 2 years after NICU discharge, females born extremely preterm with high gains in weight/length or weight have greater odds of obesity at 10 years, but not at 15 years. Infants with high growth gains in the 2 years after NICU discharge have neurocognitive and psychiatric outcomes in middle childhood and adolescence similar to those of infants with lower gains in weight and weight/length.

Are Gross Motor Skill Interventions an Equitable Replacement for Outdoor Free Play Regarding Children's Physical Activity?

PURPOSE

The purpose of this study was to determine if children engaged in equal amounts of physical activity during an established gross motor skill intervention (the Children's Health Activity Motor Program (CHAMP)) and outdoor free play.

DESIGN

Cross-sectional study; sample: Ninety-nine children (Mage = 4.21, 51% boys) were randomly divided into two movement environments: CHAMP (n = 55) or control/outdoor free play (n = 44).

MEASURES

Physical activity was assessed using GT3X+ Actigraph accelerometers worn on the waist across four mornings. Average physical activity across the four days during either CHAMP or outdoor free play was extracted and categorized as light, moderate, vigorous, or MVPA. Physical activity data were reduced in the Actilife software using the cutpoints from Evenson et al.

ANALYSIS

A 2 (treatment) x 2 (sex) mixed measures ANOVA was used to compare the amount of time children spent in light, moderate, vigorous, and MVPA.

RESULTS

There was a significant main effect for treatment for light PA (F(3,95) =13.60, P<.001, partial η2=.125), and post hoc t-tests support that children in the control/outdoor free play group engaged in more light PA compared with children in CHAMP (t95 = -3.75, P<.001).

CONCLUSIONS

Results show that children in CHAMP engaged in less light PA but equal amounts of all other physical activity behaviors than their peers in outdoor free play.

Obesity in young children and its relationship with diagnosis of asthma, vitamin D deficiency, iron deficiency, specific allergies and flat-footedness: A systematic review and meta-analysis

There is evidence that a number of medical conditions and co-morbidities are associated with obesity in young children. This review explored whether there is evidence of associations with other conditions or co-morbidities. Observational studies of young children (mean age < 10 years) were identified using electronic searches of five databases (MEDLINE, Embase, CINAHL, AMED and SPORTDiscus). Of 27 028 studies screened, 41 (comprising 44 comparisons) met the inclusion criteria. These studies provided data on five distinct diseases/conditions: asthma (n = 16), vitamin D deficiency (n = 10), iron deficiency (n = 10), allergies (n = 4) and flat-footedness (n = 4). Thirty-two studies were appropriate for meta-analysis using random-effects models, and revealed obesity was significantly associated with having asthma (OR 1.5, 95% CI 1.3-1.7), vitamin D deficiency (OR 1.9, 95% CI 1.4-2.5) and iron deficiency (OR 2.1, 95% CI 1.4-3.2). Heterogeneity (I2 ) ranged from 57% to 61%. Narrative synthesis was conducted for all studies. There was no evidence of a consistent association between obesity in young children and eczema, dermatitis or rhinitis due to the low number of studies. However, there was an association with flat-footedness. These results have implications for health policy and practice and families. Further research leading to a greater understanding of the associations identified in this review is suggested.

Demand for health services and drug prescriptions among overweight or obese preschool children

OBJECTIVES

To evaluate the association between excess weight and the demand of health services in preschool children compared with healthy weight.

METHODS

The data come from the Longitudinal Study of Childhood Obesity cohort (1884 4-year-old children, residing in the Madrid region, Spain) who provided information through telephone questionnaire, physical examination and electronic medical records. We defined overweight, general and abdominal obesity based on body mass index, waist circumference and waist-to-height ratio. Using mixed models of multivariable negative binomial regression we calculated the incidence rate ratio (IRR) regarding primary care (PC) doctor visits, drug prescriptions and hospital admissions by weight status at the end of the 2-year follow-up.

RESULTS

Childhood general obesity was associated with a higher demand for PC services related to psychological problems (IRR=1.53; 95% CI 1.02 to 2.28) and childhood abdominal obesity, according to waist-to-height ratio, was related to more frequent problems of the musculoskeletal system (IRR=1.27; 95% CI 1.00 to 1.62). Drugs were prescribed more frequently to children falling under all three definitions of excess weight, compared with healthy weight children. No differences in the number of hospital admissions were observed.

CONCLUSIONS

The demand of health services related to early childhood obesity was small. Nevertheless, obesity was associated with a slightly greater demand for drug prescriptions and for PC doctor visits related to psychological and musculoskeletal problems.

A Narrative Review of Medical and Genetic Risk Factors among Children Age 5 and Younger with Severe Obesity

Severe obesity defined as an age- and gender-specific body mass index ≥120% of the 95th percentile in children younger than 5 years is well recognized as a significant challenge for prevention and treatment. This article provides an overview of the prevalence, classification of obesity severity, patterns of weight gain trajectory, medical and genetic risk factors, and comorbid disorders among young children with an emphasis on severe obesity. Studies suggest rapid weight gain trajectory in infancy, maternal smoking, maternal gestational diabetes, and genetic conditions are associated with an increased risk for severe obesity in early childhood. Among populations of young children with severe obesity seeking care, co-morbid conditions such as dyslipidemia and fatty liver disease are present and families report behavioral concerns and developmental delays. Children with severe obesity by age 5 represent a vulnerable population of children at high medical risk and need to be identified early and appropriately managed.

Neurocognitive and Health Correlates of Overweight and Obesity among Ten-Year-Old Children Born Extremely Preterm

OBJECTIVE

To assess the relationship between overweight (body mass index [BMI] percentile ≥85 and <95) and obesity (BMI ≥95 percentile) and developmental and health outcomes at 10 years of age in a cohort of individuals born extremely preterm.

STUDY DESIGN

This was an observational cohort study of children born extremely preterm and then assessed at age 10 years for neurocognitive function and parent-reported behavior and health outcomes. Participants included 871 children aged 10 years. To describe the strength of association between overweight or obesity and outcomes, we used logistic regression models adjusting for confounders. Neurocognitive function, academic achievement, parent-reported health outcome surveys, and height and weight were measured.

RESULTS

BMI category at 10 years of age was not associated with differences in intelligence, language, or academic achievement. Parents of children with obesity were more likely to report their child had asthma (OR 2.2; 95% CI 1.4-3.5), fair/poor general health (OR 3.2; 95% CI 1.4-7.5), and decreased physical function (OR 1.7; 95% CI 1.1-2.9) but less likely to have physician diagnosed attention-deficit/hyperactivity disorder (OR 0.5; 95% CI 0.3-0.97) or an individualized education plan (OR 0.6; 95% CI 0.4-0.99).

CONCLUSION

Among children born extremely preterm, an elevated BMI, compared with normal or low BMI, is not associated with a difference in neurocognitive function. However, asthma, fair/poor general health, and decreased physical function were more prevalent among study participants with obesity, and attention-deficit/hyperactivity disorder and individualized education plan were less prevalent.

Preschoolers' health-related quality of life following the implementation of a childcare physical activity intervention

Being active offers many physical and emotional benefits contributing to a higher health-related quality of life (HRQoL); however, this relationship remains unexplored among preschoolers (aged 2.5-5 years). This study examined the impact of the Supporting Physical Activity in the Childcare Environment (SPACE), which was an intervention implemented using a cluster randomized controlled trial on preschoolers' HRQoL. Childcare centres were randomly allocated to the experimental (n = 11) or control (n = 11) conditions, and preschoolers' HRQoL was measured using the parent-report Pediatric Quality of Life Inventory 4.0 (3 subscales: physical, psychosocial, and total HRQoL) at baseline, post-intervention (i.e., week 8), and 6- and 12-month follow-up. A linear mixed-effects model was used to determine if preschoolers in the experimental condition displayed an increased HRQoL post-intervention and at follow-up compared with preschoolers in the control condition. Preschoolers (n = 234) with HRQoL data at baseline and one additional time-point were retained for analyses. Body mass index was not found to impact significantly on the intervention, and no statistically significant interaction effects were found for any of the 3 HRQoL variables. In conclusion, the SPACE intervention had no impact on preschoolers' HRQoL. Given the scarcity of research in this population, additional exploration is necessary to better understand the potential impact of physical activity participation on preschoolers' HRQoL.

A systematic review of the relationship between asthma, overweight, and the effects of physical activity in youth

PURPOSE

The association of asthma and overweight in youth is well studied. However, the temporal relationship between asthma and overweight, the strength of their association, and mediating factors involved in this relationship remain unclear. This review investigates the relationship between asthma and overweight in youth, while examining the role of physical activity as a mediator.

METHODS

A systematic review of literature was conducted using PubMed and Medline databases. Studies conducted among youth aged 0-18 years, published in English between 2000-2014 were included. The Strengthening the Reporting of Observational Studies in Epidemiology guidelines were consulted to evaluate quality of selected citations.

RESULTS

A comprehensive search yielded 143 studies in PubMed and 133 studies in Medline databases. Of these, 75 studies met the eligibility criteria. The review found varying hypotheses regarding the temporal relationship between asthma and overweight in youth; existing evidence supports the mediation of this association by decreased expenditure of energy due to reduced physical activity. Negative self-perception or parental perception of exercise ability due to asthma symptoms secondary to physical exertion was identified as a determinant of physical activity in asthmatic youth.

CONCLUSIONS

Physical activity likely mediates the relationship between asthma and overweight in youth. Temporality of this relationship remains unclear.

Treating Obesity in Preschoolers: A Review and Recommendations for Addressing Critical Gaps

Developing interventions targeting obesity reduction in preschoolers is an emergent area. Although intensive, multicomponent interventions seem a promising approach to preschool obesity reduction, this review identifies and discusses approaches to 3 critical gaps (poor reach to families from low-income and minority backgrounds, lack of sufficient evidence to determine the most effective and efficient treatment components and approaches to treating obesity in early childhood, and lack of consensus on how best to discern intervention effectiveness) that need to be addressed to advance the preschool obesity literature.

Hispanic Parental Perceptions of Child Weight in Preschool-Aged Children: An Integrated Review

BACKGROUND

Obesity continues to disproportionately affect ethnic minorities. Parents play an integral role in early childhood, and parental perceptions regarding their child's weight are key to obesity prevention. Cultural differences contribute to parental perceptions, and increased understandings of these characteristics provide a basis to address obesity in high-risk populations at an earlier age. The aim of this integrative review was to analyze extant literature to identify Hispanic parental perceptions of their preschool-aged child's weight status.

METHODS

An integrative review of studies measuring Hispanic parental perception was conducted. Computerized searches were completed using MEDLINE, PubMed, CINHAL, Eric, and PsychINFO. Articles were included if they were English, included children 2-5 years of age, included a Hispanic population, and evaluated parental perception of their child's weight status. A total of 14 articles (n=8 qualitative; n=6 quantitative) met criteria and were included in the review. Cooper's integrative review methodology was used, and articles were evaluated for quality using Polit and Beck's evidence hierarchy leveling system.

RESULTS

The results revealed six themes of Hispanic parental perceptions relative to their preschool-aged child's weight: parental perception of body weight; relationship between child weight and health; causes and consequences of overweight; familial roles and influences on child weight; prevention of overweight; and cultural influences within the United States.

CONCLUSIONS

This review highlights the importance of developing sociocultural approaches to addressing childhood obesity within the Hispanic population. Additional research is needed to incorporate what is known about Hispanic parental perceptions to positively influence behavior change during early childhood.

Changes in parent motivation predicts changes in body mass index z-score (zBMI) and dietary intake among preschoolers enrolled in a family-based obesity intervention

OBJECTIVES

To examine whether changes in parent motivation over the course of a pediatric obesity intervention are significantly associated with long-term changes in treatment outcomes. 

METHODS

 Study hypotheses were tested with a secondary data analysis of a randomized controlled trial (N = 42). Study analyses tested whether baseline to posttreatment change in total score for a self-report parent motivation measure (Parent Motivation Inventory [PMI]) was significantly associated with baseline to 6-month follow-up changes in body mass index z-score (zBMI), dietary variables, and physical activity. 

RESULTS

 Increases in PMI were significantly associated with decreased zBMI, decreased consumption of sugar-sweetened beverages and sweets, and increased consumption of artificially sweetened beverages. 

CONCLUSIONS

 Given that increases in parent motivation were associated with some treatment benefits, future research should evaluate the impact of directly assessing and targeting parent motivation on weight outcomes for preschoolers participating in a weight management program.

Preschoolers' parent-rated health disparities are strongly associated with measures of adiposity in the Lifeways cohort study children

OBJECTIVE

To examine the relationship between lifecourse factors from preschoolers' microecosystem and their parent-reported (mother-reported) health (PRH), following them prospectively from preconception to age 5 years. To investigate if preschoolers' body mass index (BMI) and waist circumference were associated with preschoolers' PRH when controlled for lifecourse predictors.

DESIGN

Lifeways cross-generation cohort study.

SETTING

Ireland.

PARTICIPANTS

Of 1082 families, 62% mothers responded on a health and lifestyle questionnaire at follow-up. Food frequency, BMI and waist circumference were measured. There were 547 family data sets available for analysis of children's PRH.

MAIN OUTCOME MEASURE

Mother-reported children's PRH at age 5. Associations with child's individual and familial exposures from preconception to age 5 years examined using logistic regression.

RESULTS

In univariate analysis, relatively positive rating of children's PRH were associated with children's lower intake of fats (OR (95% CI) 2.2 (1.1 to 4.3)), higher intake of fruits/vegetables (OR (95% CI) 2.2 (1.1 to 4.3)); as well as familial socioeconomic characteristics {higher household income (OR (95% CI) 3.0 (1.6 to 5.9)), non-entitlement to means-tested healthcare (OR (95% CI) 2.1 (1.0 to 4.3)), mothers' higher education (OR (95% CI) 1.9 (1.0 to 3.6))}, psychosocial characteristics {father's participation in study (OR (95% CI) 2.1 (1.0 to 4.3)), mothers' perceiving better support from partner (OR (95% CI) 2.3 (1.2 to 4.3)), children (OR (95% CI) 1.9 (1.0 to 3.7)) or relatives (OR (95% CI) 2.2 (1.1 to 4.1))}, parents' lifestyle {mothers' lower intake of energy (OR (95% CI) 2.2 (1.1 to 4.3)), fathers' non-smoking status (OR (95% CI) 2.2 (1.1 to 4.4))} and parents' health {mothers' self-rated health relatively positive (OR (95% CI) 5.1 (2.6 to 9.9)), fathers' self-rated health relatively positive (OR (95% CI) 3.0 (1.5 to 6.0))}. In multivariable analysis (χ(2)=34.2, df=21, N=303, R(2 )= 0.26, p<0.05), one of the two strong predictors of children's relatively positive PRH was child not being obese by International Obesity Task Force classification (OR (95% CI) 5.5 (1.4 to 21.0)), observed also using BMI (kg/m(2); OR (95% CI) 0.73 (0.58 to 0.93)) or waist circumference (cm; OR (95% CI) 0.89 (0.81 to 0.98)) as continuous variables. The other significant predictor was mothers' self-rated health relatively positive (OR (95% CI) 4.2 (1.5 to 12.2)).

CONCLUSIONS

Preschoolers' health is adversely associated with obesity and this is independent of lifecourse and social and environmental inequalities. The findings suggest that reducing childhood obesity and improving maternal health may be useful ways to improve child's global health.

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

Childhood obesity and asthma are on the rise in the U.S. Clinical and epidemiological data suggest a link between the two, in which overweight and obese children are at higher risk for asthma. Prevention of childhood obesity is preferred over treatment, however, in order to be receptive to messages, parents must perceive that their child is overweight. Many parents do not accurately assess their child’s weight status. Herein, the relation between parental perceptions of child weight status, observed body mass index (BMI) percentiles, and a measure of child feeding practices were explored in the context of asthma, food allergy, or both. Out of the children with asthma or food allergy that were classified as overweight/obese by BMI percentiles, 93% were not perceived as overweight/obese by the parent. Mean scores for concern about child weight were higher in children with both asthma and food allergy than either condition alone, yet there were no significant differences among the groups in terms of pressure to eat and restrictive feeding practices. In summary, parents of children with asthma or food allergy were less likely to recognize their child’s overweight/obese status and their feeding practices did not differ from those without asthma and food allergy.

Severe obesity in children and adolescents: identification, associated health risks, and treatment approaches: a scientific statement from the American Heart Association

Severe obesity afflicts between 4% and 6% of all youth in the United States, and the prevalence is increasing. Despite the serious immediate and long-term cardiovascular, metabolic, and other health consequences of severe pediatric obesity, current treatments are limited in effectiveness and lack widespread availability. Lifestyle modification/behavior-based treatment interventions in youth with severe obesity have demonstrated modest improvement in body mass index status, but participants have generally remained severely obese and often regained weight after the conclusion of the treatment programs. The role of medical management is minimal, because only 1 medication is currently approved for the treatment of obesity in adolescents. Bariatric surgery has generally been effective in reducing body mass index and improving cardiovascular and metabolic risk factors; however, reports of long-term outcomes are few, many youth with severe obesity do not qualify for surgery, and access is limited by lack of insurance coverage. To begin to address these challenges, the purposes of this scientific statement are to (1) provide justification for and recommend a standardized definition of severe obesity in children and adolescents; (2) raise awareness of this serious and growing problem by summarizing the current literature in this area in terms of the epidemiology and trends, associated health risks (immediate and long-term), and challenges and shortcomings of currently available treatment options; and (3) highlight areas in need of future research. Innovative behavior-based treatment, minimally invasive procedures, and medications currently under development all need to be evaluated for their efficacy and safety in this group of patients with high medical and psychosocial risks.

Impaired parent-reported health-related quality of life of underweight and obese children at elementary school entry

PURPOSE

Examine the health-related quality of life of 5-6-year-old underweight, overweight and obese children.

METHODS

Our cross-sectional study included 3,227 parent-child dyads from the "Be active, eat right" study. Parents completed questionnaires regarding child and parental characteristics. Health-related quality of life of the child was measured using the Child Health Questionnaire Parent Form 28. Children were classified normal weight, overweight, obese, severely obese, and underweight according to the international age and gender BMI cutoff points. Bootstrap analyses were performed for general linear models corrected for potential confounding variables.

RESULTS

Severely obese children (β, -2.60; 95% CI, -4.80 to -0.57, p < 0.01) and underweight children (β, -1.11; 95% CI, -1.85 to -0.39, p < 0.01) had lower parent-reported scores on the physical summary scale. On the physical functioning profile scale parents of overweight and severely obese children also reported statistically significant lower scores (p < 0.05 and p < 0.01, respectively).There were no significant differences regarding the psychosocial summary scale scores between the different weight categories.

CONCLUSION

Underweight and overweight children experience impaired health-related quality of life on the physical functioning domain. Physicians, teachers and parents should be aware of the possible negative impact on health-related quality of life in underweight and overweight 5-6-year-old children.

Obesity and asthma at school entry: co-morbidities and temporal trends

AIM

A decline in asthma prevalence from 2000 to 2005 was reported previously. The objective is to examine the temporal trends for the prevalence of obesity and other childhood disorders and consider the extent to which associations between asthma and other co-morbidities can be accounted for by body mass index.

METHODS

Serial cross-sectional surveys of primary school entrants (n = 18,999) in the Australian Capital Territory between 2001 and 2005 were used. Asthma, recent respiratory symptoms and diabetes data were extracted from parental reports. Anthropometric measurements were obtained from health assessments by school nurses. Child obesity was defined using the age and sex-specific Cole criteria. Time trends for the prevalence of obesity and other disorders, and the association between 'current asthma' and co-morbidities were analysed using multiple logistic regression and other analyses.

RESULTS

Obesity prevalence was 5.24% in 2001 decreasing to 3.60% in 2005 (test of linear trend P = 0.02). Overweight (adjusted odds ratio (AOR) 1.30 (95% confidence interval (CI) 1.16, 1.46), P < 0.001) and obese (AOR 1.36 (95% CI 1.13, 1.62), P = 0.001) children were more likely to report 'asthma ever'. Children with diabetes (AOR 9.35 (95% CI 3.11, 28.12, P < 0.001)) and attention deficit (AOR 3.39 (95% CI 2.04, 5.64), P < 0.001) were more likely to report 'current asthma'.

CONCLUSIONS

The pattern of association with co-morbidities was different for asthma and obesity. The temporal decline/plateau effect in 'current asthma' could not be explained by concurrent body mass index changes. The decline in obesity was largely driven by the 2005 findings. Longer term trends need to be evaluated further.

Parental perceptions of and concerns about child's body weight in eight European countries--the IDEFICS study

OBJECTIVES

To evaluate parental perceptions of and concern about child's body weight and general health in children in a European cohort.

DESIGN

Cross-sectional multi-centre study in eight European countries.

PARTICIPANTS

16,220 children, ages 2-9 years.

METHODS

Parents completed a questionnaire regarding children's health and weight and concern about overweight and underweight. Objective children's weight categories from the International Obesity Task Force were used. Logistic regression models were utilized to identify predictors of accurate weight perception.

RESULTS

Parental weight perception corresponded overall to children's mean body mass index (BMI) z-scores, with important exceptions. About one-third of the total indicated concern about underweight, paradoxically most often parents of children in the overweight or obesity categories. In 63%, parents of children in the overweight category marked 'proper weight'. The strongest predictor for accurate parental weight perception for children with overweight and obesity was BMI z-score (odds ratio [OR] = 7.2, 95% confidence interval [CI] 6.1-8.7). Compared to Southern Europe, ORs for accurate parental weight perception were 4.4 (95% CI 3.3-6.0) in Northern Europe and 3.4 (95% CI 2.7-4.2) in Central Europe.

CONCLUSION

Parents of children categorized as being overweight or obese systematically underestimated weight. Parents differed regionally regarding accurate weight perception and concern about overweight and underweight.

Associations between obesity and comorbid mental health, developmental, and physical health conditions in a nationally representative sample of US children aged 10 to 17

OBJECTIVE

This large population-based study of US children considered the association of obesity with a broad range of comorbidities. This study examined relationships between weight status and health for US children.

METHODS

We performed cross-sectional analysis of data on 43,297 children aged 10 to 17 from the 2007 National Survey of Children's Health. Weight status was calculated from parent report of child height and weight. Logistic regression models assessed associations between weight status and 21 indicators of general health, psychosocial functioning, and specific health disorders, adjusting for sociodemographic factors.

RESULTS

Using body mass index (BMI) percentiles for age and sex, 15% of US children were considered overweight (BMI 85th to <95th percentile), and 16% were obese (BMI ≥95th percentile). Compared with children classified as not overweight, obese children were more likely to have reported good/fair/poor health (adjusted odds ratio [AOR] 2.18, 95% confidence interval [CI] 1.76-2.69), activity restrictions (AOR 1.39, 95% CI 1.10-1.75), internalizing problems (AOR 1.59, 95% CI 1.04-2.45), externalizing problems (AOR 1.33, 95% CI 1.07-1.65), grade repetition (AOR 1.57, 95% CI 1.24-1.99), school problems, and missed school days. Attention deficit/hyperactivity disorder, conduct disorder, depression, learning disability, developmental delay, bone/joint/muscle problems, asthma, allergies, headaches, and ear infections were all more common in obese children.

CONCLUSIONS

Obese children have increased odds of worse reported general health, psychosocial functioning, and specific health disorders. Physicians, parents, and teachers should be informed of the specific comorbidities associated with childhood obesity to target interventions that could enhance well-being. Future research should examine additional comorbidities and seek to confirm associations using longitudinal data and clinical measures of height and weight.

Impaired health-related quality of life in preschoolers with obesity

OBJECTIVES

To examine whether health-related quality of life (HRQOL) for treatment-seeking preschoolers with obesity (N = 60) differed from preschoolers in a nonclinical comparison sample (N = 457).

METHODS

Parents in both samples completed the parent-proxy form of the pediatric quality of life inventory (PedsQL). Between-group comparisons were conducted to examine differences for all scales and summary scores of the PedsQL.

RESULTS

Parent proxy-reported HRQOL was significantly lower for treatment-seeking preschoolers with obesity for all scales and summary scores except school functioning. Differences on the total scale score met the criterion for being a clinically important difference.

CONCLUSIONS

Our study suggests treatment-seeking families perceive worse HRQOL for children with obesity as early as the preschool years. Discussion of HRQOL may be a more effective strategy for health care professionals in broaching the topic of weight with parents and identifying families who may be more receptive to weight management suggestions for preschoolers.

Asthma and obesity in three-year-old urban children: role of sex and home environment

OBJECTIVE

To examine whether the relationship between obesity and asthma in young girls and boys can be explained by social and physical characteristics of the home environment.

STUDY DESIGN

We examined the relationship between asthma and obesity in children in the Fragile Families and Child Wellbeing Study (n=1815). Asthma was determined through maternal report of asthma diagnosis by a doctor (active in past 12 months). Weight and height of child was measured during an in-home visit. Data on home social (maternal depression, intimate partner violence) and physical environmental factors (housing quality, tobacco exposure) were collected via questionnaire.

RESULTS

Ten percent of children had active asthma, 19% of children were overweight, and 17% of children were obese. In fully adjusted models, obese children had twice the odds of having asthma (OR, 2.3; 95% CI, 1.5-3.3) compared with children of normal body weight. In stratified analyses, overweight boys, but not overweight girls, had increased of odds of asthma. Obese boys and girls had increased odds of asthma compared with boys and girls of normal body weight.

CONCLUSION

The relationship between asthma and obesity is present in boys and girls as young as 3 years of age; a relationship between being overweight and asthma is only present among boys. This relationship is not attributable to shared social and environmental factors of the children's home.
