A shift from underweight to overweight and obesity in Asian children and adolescents with congenital heart disease

Consumption and Breakfast Patterns in Children and Adolescents with Congenital Heart Disease

Little is known about skipping breakfast and breakfast patterns (BP) and their evaluation according to sociodemographic, clinical, lifestyle, cardiometabolic and nutritional data in children and adolescents with congenital heart disease (CHD). This cross-sectional study with 232 children and adolescents with CHD identified the prevalence and patterns of the breakfast, described these according to sociodemographic, clinical and lifestyle characteristics, and assessed their association with cardiometabolic and nutritional markers. Breakfast patterns were identified by principal components, and bivariate and linear regression analysis were applied. Breakfast consumption was observed in 73% of participants. Four BP were identified: pattern 1 "milk, ultra-processed bread, and chocolate milk", pattern 2 "margarine and processed bread", pattern 3 "cold meats/sausages, cheeses and butter/cream" and pattern 4 "fruits/fruit juices, breakfast cereals, yogurts, and homemade cakes/pies and sweet snacks". Family history for obesity and acyanotic CHD were associated with breakfast skipping. Younger participants and greater maternal education were associated with greater adherence to pattern 1 and pattern 4. Older participants and longer post-operative time showed greater adherence to pattern 3. No association between skipping breakfast or BP and cardiometabolic and nutritional markers was observed. Nonetheless, the findings reinforce the need for nutritional guidance for healthy breakfast, aiming to reduce the consumption of ultra-processed foods and to prioritize fresh and minimally processed foods.

Moderate and Severe Congenital Heart Diseases Adversely Affect the Growth of Children in Italy: A Retrospective Monocentric Study

Children with congenital heart disease (CHD) are at increased risk for undernutrition. The aim of our study was to describe the growth parameters of Italian children with CHD compared to healthy children. We performed a cross-sectional study collecting the anthropometric data of pediatric patients with CHD and healthy controls. WHO and Italian z-scores for weight for age (WZ), length/height for age (HZ), weight for height (WHZ) and body mass index (BMIZ) were collected. A total of 657 patients (566 with CHD and 91 healthy controls) were enrolled: 255 had mild CHD, 223 had moderate CHD and 88 had severe CHD. Compared to CHD patients, healthy children were younger (age: 7.5 ± 5.4 vs. 5.6 ± 4.3 years, p = 0.0009), taller/longer (HZ: 0.14 ± 1.41 vs. 0.62 ± 1.20, p < 0.002) and heavier (WZ: -0,07 ± 1.32 vs. 0.31 ± 1.13, p = 0.009) with no significant differences in BMIZ (-0,14 ± 1.24 vs. -0.07 ± 1.13, p = 0.64) and WHZ (0.05 ± 1.47 vs. 0.43 ± 1.07, p = 0.1187). Moderate and severe CHD patients presented lower z-scores at any age, with a more remarkable difference in children younger than 2 years (WZ) and older than 5 years (HZ, WZ and BMIZ). Stunting and underweight were significantly more present in children affected by CHD (p < 0.01). In conclusion, CHD negatively affects the growth of children based on the severity of the disease, even in a high-income country, resulting in a significant percentage of undernutrition in this population.

Cardiopulmonary Fitness of Preschoolers with Congenital Heart Disease: An Observational Study

With advancements in cardiopulmonary rehabilitation over the past few decades, the survival rate of patients with congenital heart disease (CHD) has increased. However, the Cardiopulmonary fitness (CPF) of these patients is poor. Here, we aimed to investigate CPF in preschoolers with CHD (aged 4 to 6 years) using cardiopulmonary exercise testing. We retrospectively compared 102 healthy preschoolers with 80 preschoolers with CHD. The latter had lower peak oxygen consumption, oxygen consumption at anaerobic threshold and metabolic equivalent at anaerobic threshold. The same result was observed in boys with CHD, but not in girls, when sex was sub-analyzed. Considering the body composition, children with CHD had a lower fat-free mass index (FFMI) than their healthy peers. Healthy preschoolers with a normal body mass index (BMI) had higher anaerobic threshold and peak metabolic equivalent values than overweight or underweight children. This was categorized under the BMI reference of the Ministry of Health and Welfare in Taiwan. In conclusion, the CPF difference between the CHD and healthy groups was identified as early as in preschool age, and better CPF in healthy preschoolers within the normal BMI range suggests the importance of weight control in young children.

Congenital Heart Disease: Growth Evaluation and Sport Activity in a Paediatric Population

(1) Objective: To evaluate: (i) the associations of age and disease severity with anthropometric indices and weight status, (ii) the difference in the frequency of sports activity among different levels of disease severity in paediatric patients with congenital heart disease (CHD). (2) Methods: Clinical data of Caucasian children (aged 2–18 years) diagnosed with CHD (2005–2018) were retrospectively collected from the electronic register of outpatient visits. Of the 475 children with CHD, 368 children and their 1690 complete anthropometric measurements were eligible for inclusion in our analysis. (3) Results: Significant increase with age was observed for weight z-score [beta (95%CI): 0.03 (0.02, 0.05) for one-unit of age] and BMI z-score [0.06 (0.03, 0.08)] but not for height z-score. The probability of being underweight and overweight/obese increased and decreased with disease severity, respectively. The obesity probability of patients with mild CHD (0.06 [95%CI: 0.03, 0.08]) was not statistically distinguishable from that of patients with moderate CHD (0.03 [95%CI: 0.02, 0.05]), whereas it was lower in patients with severe CHD (0.004 [95%CI: 0.0, 0.009]). No obese patients with a univentricular heart defect were observed. Days spent in sport activities were equal to 1.9 [95%CI: 1.6, 2.2] days/week, 1.9 [1.5, 2.2], 1.4 [1.1, 1.7] and 0.7 [0.1, 1.3] in patients with mild, moderate, severe and univentricular CHD, respectively. (4) Conclusions: The risk of being overweight and obese should not be underestimated in paediatric patients diagnosed with CHD, especially in children with mild or moderate heart defects. It could be prevented or reduced by promoting a healthy lifestyle.

Making every contact count: recognising obesity in paediatric and young adult cardiology

INTRODUCTION

With increased survival, children with CHD are reaching adulthood, however, obesity amongst this cohort is an emerging problem. Making every contact count encourages clinicians to utilise contact to elicit behaviour change. The aim of this work was to identify whether the body habitus of children classified as obese was addressed during a clinical review.

METHODS

A retrospective observational cohort study was completed using a cardiology outpatient dataset from 2010 to 2019. Inclusion criteria are all children with a body mass index z score classified as obese (≥ 2 z scores). Individual electronic patient records were reviewed to identify long-term anthropometric measures including (i) recognition of body habitus, (ii) prescription of physical activity or dietary intervention, and (iii) referral to a weight management programme or dietitian.

RESULTS

From the cohort of 95 patients, 285 "obese clinical encounters" were identified, at the time of a cardiology clinic attendance. Of those, obesity was acknowledged in 25 clinic letters (8.65%), but only 8 used the correct terms "obese" or "obesity" (2.77%). Action to tackle obesity was recorded in 9.3% of cases with a direct referral to a dietitian being made on 3 occasions (1.04%).

CONCLUSIONS

Body habitus is not being routinely addressed by cardiologists caring for paediatric and young adult cardiac patients. This study has recognised an alarmingly high incidence of missed opportunities to make every contact count, to manage those with obesity and associated risk factors.

Overweight and Obesity in Patients with Congenital Heart Disease: A Systematic Review

Background: Overweight and obesity have become a major public health concern in recent decades, particularly in patients with chronic health conditions like congenital heart disease (CHD). This systematic review elaborates on the prevalence and the longitudinal development of overweight and obesity in children and adults with CHD. Methods: A systematic literature search was conducted in PubMed, Cochrane, and Scopus from January 2010 to December 2020 on overweight and obesity prevalence in children and adults with CHD. Results: Of 30 included studies, 15 studies evaluated 5680 pediatric patients with CHD, 9 studies evaluated 6657 adults with CHD (ACHD) and 6 studies examined 9273 both pediatric patients and ACHD. Fifteen studies received the quality rating “good”, nine studies “fair”, and six studies “poor”. In children with CHD, overweight prevalence was between 9.5–31.5%, and obesity prevalence was between 9.5–26%; in ACHD, overweight prevalence was between 22–53%, and obesity was between 7–26%. The prevalence of overweight and obesity was thereby similar to the general population. Overweight and obesity have been shown to increase with age. Conclusion: The prevalence of overweight and obesity in children and adults with CHD is similar to the general population, demonstrating that the growing obesity pandemic is also affecting the CHD population.

Coronary artery disease in patients with congenital heart defects

The prognosis of patients with congenital heart defects has improved significantly: more and more patients reach adulthood and old age. At the same time, the possibility of cardiovascular morbidity increases. The conventional risk factors for coronary artery disease are at least as high or even higher in patients than in the general population. Obesity and sedentary life style are more common in adults with congenital heart defect (ACHD) than in general population. In some patients, for example those with coarctation of the aorta or patients with operated coronary arteries in the infancy, the incidence of coronary artery disease (CAD) is clearly increased. In some patients with cyanotic heart defects (e.g. Fontan), the incidence of CAD might be lower, but it usually returns to the average level or higher after correction of the defect. Coronary artery disease is one of the most important reasons for mortality also in ACHD patients, and the consequences of a coronary event might be more fateful in a patient with a corrected congenital heart defect than in her/his peer. There should be a paradigm shift from operative mortality and short-term outcome to long-term morbidity and prevention of cardiovascular disease - a task that often has been forgotten during follow-up visits.

Added sugar and trans fatty acid intake and sedentary behavior were associated with excess total-body and central adiposity in children and adolescents with congenital heart disease

BACKGROUND

Over the past three decades, the prevalence rate of overweight and obesity has increased in survivors with congenital heart disease, and little is known about the body composition and its association with clinical characteristics and lifestyle factors.

OBJECTIVES

To evaluate excess total-body adiposity and central adiposity and, to describe associated factors.

METHODS

Cross-sectional study with children and adolescents who underwent procedure to treat congenital heart disease, from January to July 2017. Sociodemographic and clinical characteristics, and lifestyle factors (dietary intake, physical activity, and sedentary behavior) were assessed. Adiposity was assessed using air-displacement plethysmography and waist circumference. Factors associated with excess total-body adiposity and central adiposity were analyzed using logistic regression models.

RESULTS

Of 232 patients, 22.4% were identified with excess total-body adiposity and 24.6% with central adiposity. Significant factors positively associated with excess total-body adiposity were intake of added sugar and trans fatty acids, adjusted for confounding factors. Similarly, lifestyle factors were positively associated with central adiposity: intake of added sugar and trans fatty acids, sedentary behavior, and family history of obesity.

CONCLUSIONS

Lifestyle factors were associated with excess total-body adiposity and central adiposity. Assessment of body composition and healthy-lifestyle counseling into outpatient care may be the key point to prevent obesity in children and adolescents with congenital heart disease.

Energy Balance-Related Behaviors and Body Mass Index in Asian School-Aged Children With Congenital Heart Disease

BACKGROUND

Overweight/obesity is a substantial global public health concern, which can be caused by genetic factors and energy balance-related behaviors (EBRBs). If it occurs in children with congenital heart disease (CCHD), it can yield an extra burden on their health. Most studies on CCHD have taken place in Western societies, leaving Asian populations understudied, especially children.

OBJECTIVE

We sought (1) to determine body mass index distribution among school-aged CCHD in Taiwan, (2) to ascertain whether the body mass index of CCHD differs from that of the general population, (3) to describe EBRBs in CCHD, and (4) to identify factors associated with underweight and overweight/obesity among CCHD.

METHODS

In this cross-sectional study, 97 child-parent dyads (53.6% boys; mean age, 9.73 years; 25.8% moderate-to-severe heart conditions) were enrolled. Self-administered questionnaires were used to collect demographics, medical factors, food frequency, physical activity, and sedentary behaviors. Anthropometric measurements were taken in the hospital. Independent predictors of EBRBs and health conditions were calculated through logistic regression analysis.

RESULTS

Among Taiwanese CCHD, 19.6% were underweight and 14.4% were overweight/obese. Children with moderate-to-severe heart defects were more often underweight. Body mass index did not differ between CCHD and children in the general population. More complex heart defects and asthma were associated with being underweight, whereas sedentary behaviors, cardiomegaly, and the New York Heart Association classification II to IV were associated with being overweight/obese.

CONCLUSIONS

Sedentary lifestyle is seemingly the only EBRB correlated with being overweight. Physical activity programs for children may help prevent and treat overweight or obesity in Asian CCHD, similar to Western countries.

Chylothorax following paediatric cardiac surgery: a case-control study

OBJECTIVES

The aims of this study were to investigate risk factors for the development of postoperative chylothorax following paediatric congenital heart surgery and to investigate the impact of a management guideline on management strategies and patient outcome.

METHODS

All patients with chylothorax following cardiac surgery at the Royal Children's Hospital, Melbourne, over a 48-month period beginning in January 2008 were identified. A control group, matched for age, date of surgery, and sex, was identified. To investigate potential risk factors, univariable and multivariable logistic regression models were constructed with paired analysis. To examine the effect of a standardised management protocol, data before and after the implementation of the guideline were compared.

RESULTS

In total, 121 cases of chylothorax were identified, with 121 controls, matched for age at surgery, date of surgery, and sex. The incidence of chylothorax was 5.23%. Increasing surgical complexity (univariable OR 0.17 for the least complex versus the most complex group, p=0.02), closed-heart surgeries (OR 0.07 for open versus closed, p<0.001), and redo chest incisions (OR 10.0 for redo versus virgin, p<0.001) were significantly associated with chylothorax. The standardised management protocol had no significant impact on either drainage duration or management strategy.

CONCLUSIONS

We have replicated the previously reported association between surgical complexity and chylothorax risk, and have shown, for the first time, that redo chest openings are also associated with a significantly increased risk. The implementation of a standardised management protocol in our institution did not result in a significant change in either chylothorax drainage duration or management strategy.

Composite marginal quantile regression analysis for longitudinal adolescent body mass index data

Childhood and adolescenthood overweight or obesity, which may be quantified through the body mass index (BMI), is strongly associated with adult obesity and other health problems. Motivated by the child and adolescent behaviors in long-term evolution (CABLE) study, we are interested in individual, family, and school factors associated with marginal quantiles of longitudinal adolescent BMI values. We propose a new method for composite marginal quantile regression analysis for longitudinal outcome data, which performs marginal quantile regressions at multiple quantile levels simultaneously. The proposed method extends the quantile regression coefficient modeling method introduced by Frumento and Bottai (Biometrics 2016; 72:74-84) to longitudinal data accounting suitably for the correlation structure in longitudinal observations. A goodness-of-fit test for the proposed modeling is also developed. Simulation results show that the proposed method can be much more efficient than the analysis without taking correlation into account and the analysis performing separate quantile regressions at different quantile levels. The application to the longitudinal adolescent BMI data from the CABLE study demonstrates the practical utility of our proposal. Copyright © 2017 John Wiley & Sons, Ltd.

Serum C-reactive protein levels and body mass index in children and adolescents with CHD

BACKGROUND

The prevalence of overweight in children with CHD is about 26.9%. Increase in adipose tissue is related to the secretion of proinflammatory markers such as C-reactive protein. Assuming that children with CHD are exposed to other inherent risk factors for heart disease, our objective was to evaluate the correlation between levels of C-reactive protein and body mass index in children and adolescents with CHD.

METHODS

A cross-sectional study with 377 children and adolescents with CHD in a clinical setting of a reference hospital was carried out. C-reactive protein data were collected after 12 hours of fasting. Nutritional status was classified according to body mass index. The patients were divided into three groups: cyanotic, acyanotic, and minimal heart defects (controls).

RESULTS

The mean age was 9.9±4.2 years, and 53.6% of the sample included males. The cyanotic group represented 22.3%, acyanotic 42.2%, and minimal defects 35.5% of the sample. The average body mass index percentile was 57.23±32.06. The median values of C-reactive protein were as follows: cyanotic 0.340, acyanotic with clinical repercussion 0.203, and minimal defects 0.128. There was a significant difference between the minimal defects and the cyanotic groups (p=0.023). There was a significant correlation between C-reactive protein and body mass index percentile (r=0.293, p<0.01). C-reactive protein levels were higher in girls (p=0.034). There were no significant correlations between C-reactive protein and age or birth weight.

CONCLUSION

The correlation between body mass index percentile and C-reactive protein was confirmed in this population. The prevention of overweight is paramount to avoid overlapping modifiable risk factors to those already inherent to the CHD.

Congenital heart disease and the prevalence of underweight and obesity from age 1 to 15 years: data on a nationwide sample of children

OBJECTIVE

We examined the prevalence of underweight and obesity in children with congenital heart disease (CHD) compared with the general population.

METHODS

Using the Danish National Patient Registry, we identified individuals born and diagnosed with CHD in Denmark during 1996-2012 who were alive at 1 year of age. A unique personal identifier enabled identification of CHD subjects, as well as birth year and sex-matched (1:10) general population controls. The Children's Database has recorded height and weight measured by clinical providers at preventive health checks offered to all children in Denmark. Data recording were made mandatory in 2011. Obesity was defined as body mass index (BMI) above the 95thpercentile and underweight as BMI below the fifth percentile for age and sex. We determined the prevalence of underweight and obesity at study subjects' first height and weight recording. For those underweight at age 1 year, prevalence of underweight and obesity at later recordings was assessed.

RESULTS

We identified 9194 children with CHD of which 2679 (29%) had at least one recording of height and weight. The control cohort demonstrated a similar portion of anthropometric data: 30 047 (31%) of 96 585 controls. The prevalence of underweight and obesity at CHD study subjects' first height and weight recording was 9.7% (95% CI 8.7 to 11) and 4.1% (95% CI 3.4 to 4.9), respectively. Among individuals with CHD who were underweight at age 1 year (n=78), 51 (65%) had additional BMI recordings between ages 2 and 5 years with a subsequently diminished prevalence of underweight of 27% (95% CI 20 to 35) and none were obese.

CONCLUSION

The CHD population had an increased prevalence of underweight compared with the general population. Data indicated potential for BMI normalisation among those initially underweight at age 1 year. The prevalence of obesity in children with CHD was comparable with that of the general population.

Prevalence of overweight and obesity among patients with congenital and acquired heart disease in Kocaeli, Turkey

BACKGROUND

Childhood obesity has increased in the last half of the century. The aim of this study was to evaluate the frequency of obesity in the children with congenital or acquired heart disease.

METHODS

A total of 1410 children were assessed in this study. The study population was composed of 518 children (289 boys, 229 girls) as control group and 892 children (477 boys, 415 girls) as heart disease group. Patients were grouped into four categories: (I) "Clinic control subjects"; (II) "mild heart disease" that has not been treated with either surgical or catheter intervention; (III) congenital heart disease treated with surgical and/or catheter intervention; and (IV) "arrhythmias". A body mass index ⩾85th percentile was defined as overweight, ⩾95th percentile as obese, and <5th percentile was defined as underweight.

RESULTS

We did not detect any association between heart disease and obesity. There was no difference in the rates of overweight, obesity, and underweight between the healthy control subjects and patients with heart disease (8.1%, 13.3%, and 5.0%; 9.0%, 10.7%, and 4.7%, respectively, p=0.145). All subgroups had a similar prevalence of underweight, overweight, and obesity as the healthy control population. Within the heart disease population, the overall prevalence rates for overweight, obesity, and underweight were similar between the boys and girls.

CONCLUSION

Obesity is a common problem in children with heart disease, at least in general population. It is an important additional risk factor for long-term cardiovascular morbidity and mortality in children with heart disease. Precautions to prevent obesity should be a part of paediatric cardiologist's examination.

Are the children and adolescents with congenital heart disease living in Southwestern Ontario really overweight and obese?

OBJECTIVE

To assess the prevalence of overweight and obesity in children with congenital heart disease and compare them with age-matched healthy children in Southwestern Ontario, Canada.

METHODS

We compared the Center of Disease Control weight and body mass index z-scores of 1080 children, aged 2 to 18 years, who presented to our paediatric cardiology outpatient clinic from 2008 to 2010 for congenital heart disease with 1083 healthy controls.

RESULTS

In all, 18.2% of the children with congenital heart disease and 20.8% of healthy children were identified to be either overweight or obese. Overall, the weight category distribution had been similar between the congenital heart disease and healthy control groups, as well as between the congenital heart disease subgroups. There was no difference in normal weight and overweight/obese categories between children with congenital heart disease and healthy children. The underweight category, however, showed a significantly higher prevalence in congenital heart disease compared with healthy children (6.8 and 4.5%, respectively, p = 0.03).

CONCLUSION

The prevalence of overweight/obesity did not differ in children with congenital heart disease compared with age-matched healthy children; however, it is still high (18.2%). Obesity may represent an additional risk factor for the long-term cardiovascular health of congenital heart disease patients aside from the underlying heart defect.

Caring for a teen with congenital heart disease

Adolescents with congenital heart disease (CHD) are a rapidly growing population with complex medical needs and psychosocial challenges. Identity formation is an important developmental task accomplished during the teenage years. This article reviews different aspects of ongoing care that pertain to teenagers with CHD, with a particular focus on primary care issues and a summary of recommendations from various scientific societies. A successful smooth transition to the adult health care setting should achieve 2 important goals: to prevent loss of follow-up and to foster and encourage self-care behaviors.
