Obesity and overweight in intellectual and non-intellectually disabled children

Evaluation of factors affecting body mass index of children with intellectual disability

This study was conducted to evaluate the BMI of the children with intellectual disability and the factors affecting their BMI. This descriptive and cross-sectional study was carried out between March 2016 and April 2016 in Turkey and consisted of 135 children. Children's anthropometric measurements were and their BMI values were calculated. Categorization of children by BMI percentile according to AAP reference values was performed. There was a significant difference between the BMI categories of the children (p < 0.05) and the education level of children's father (x2 = 8.960; p = 0.028), the degree of intellectual disability (x2 = 16.113; p = 0.008), the presence of other disabilities (x2 = 22.013; p = 0.000), type of disability (x2 = 21.359; p = 0.001), the nutrient intake (x2 = 38.935; p = 0.000) and the presence of nutritional problems (x2 = 7.687; p = 0.042). Father's education level, children's degree of disability, child's having presence of other disabilities, child's being dependent in the view of nutrient intake, and child's having nutritional problems were determined as factors affecting BMI.

Mineral elements and adiposity-related consequences in adolescents with intellectual disabilities

BACKGROUND

Patients with intellectual disabilities are shown to have a limited capacity for cooperation, communication,and other biological consequences, which significantly require a specialized interest in healthcare professionals worldwide.

AIM

In this respect, the present study was designed to evaluate the levels mineral elements, and their correlation with oxidative stress markers and adiposity markers; leptin (L), adiponectin (A), and L/A ratio in adolescents with intellectual disabilities.

METHODS

A total of 350 schoolchildren aged (12-18 years) were randomly invited to participate in this prospective, observational study. Only 300 participants agreed to participate in this study. According to Intelligence quotients scores (IQ) measured by WISC-III, the participants were classified into two groups; the healthy control group (no = 180; IQ = 90-114); and the moderate intellectual disability (MID) group (no = 120; IQ = 35-49). Adiposity markers; body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), physical activity scores, adipokines biomarkers; leptin, adiponectin, L/A ratio, oxidative stress, and plasma mineral elements were evaluated by prevalidated questionnaires, inductively coupled plasma-mass spectrometry (ICP-MS), colorimetric, and immunoassay techniques.

RESULTS

Intellectual disability of moderate type was reported in 40% of the studied populations most of them are men aged 12-18 years (66.6% for men vs. 33.3 for females). Obesity was shown to be associated with the degree of intellectual disability of the students. There was a significant (P = 0.001) increase in the BMI, WHR, and WHtR scores as obesity markers with poor physical activity (P = 0.01) in students with poor disability compared to healthy controls (HC). The levels of leptin (P = 0.001), adiponectin (P = 0.01), and L/A ratio (P = 0.01) as adiposity biomarkers were significantly increased in students with MID compared to healthy controls. Also, oxidative stress measured by malondialdehyde (MDA) (P = 0.01) and total antioxidant capacity (TAC) (P = 0.01) were significantly increased in students with MID compared to healthy control subjects. In addition, mineral elements were shown to be linked with intellectual disability. The data showed that the levels of Fe, Mn, Zn, Hg, Pb, Ca, Cr, Mg, and Ni significantly (P = 0.001) increased, and the levels of Al, Na, K, Cu, and Zn/Cu ratio significantly (P = 0.001) decreased in subjects with MID compared to healthy controls. Correlation analysis concluded that changes in mineral elements significantly correlated with adiposity markers, oxidative stress, and the scores of intellectual disability (WISC III-IQ score).

CONCLUSION

The intellectual disability of moderate type (MID) was associated with abnormal changes in the levels of essential mineral elements and adipokines and increased levels of cellular oxidative stress. Thus, evaluating plasma mineral elements and adipokines levels could be a potential diagnostic parameter for diagnosing MID.

Parental experiences of adopting healthy lifestyles for children with disabilities living with overweight and obesity

BACKGROUND

Children with disabilities present with high obesity rates.

OBJECTIVE

This study explored the parental experience of adopting healthy lifestyle choices, for children with disabilities, who received dietetic weight management advice.

METHODS

Semi-structured qualitative interviews were carried out with eight parents/carers in their own homes or healthcare setting in an inner London locality, or by telephone. Data was analyzed using an interpretative phenomenological analysis (IPA) approach.

RESULTS

Five superordinate themes emerged: 1. Strategies to promote healthy lifestyles: encouraging physical activity, limiting access to food and taking a gradual approach to making lifestyle changes. 2. Challenges to adopting healthy lifestyles: selective eating patterns, the high cost of healthy foods and parental/carer lack of time. 3. The role of healthcare professionals (HCPs): revealed that not all parents/carers received advice or support, prior to dietetic referral, when managing their child's weight. Feeling reassured by HCPs was valued. Parents/carers reported a positive experience of seeing the dietitian, as they appreciated receiving practical and individualized advice. 4. Support needs: family support and support from families with children with disabilities was explored. 5. Parent/carer wellbeing: such as stress was found to have a detrimental impact on parents making healthy lifestyle changes.

CONCLUSIONS

Adopting a healthy lifestyle involved a variety of strategies and challenges, some of which are specific to this population group and should be considered by HCPs, when having weight-related discussions and offering advice. Parental/carer support needs and wellbeing should also be taken into consideration when planning weight management services for this population group.

Prevalence of overweight and obesity in children and adolescents with intellectual disabilities in China

BACKGROUND

Overweight and obesity in children and adolescents has become a worldwide epidemic. There are several studies that have concentrated on the prevalence rate of children and adolescents with intellectual disabilities (ID), whereas data on such a population on the mainland of China remain unclear. The purpose of this study was to investigate the prevalence rate of overweight and obesity among school-aged children and adolescents with ID on China's mainland.

METHODS

This study employed a cross-sectional design to examine the body weight status of 1873 children and adolescents (ages 6-18 years old) with ID in 35 special education schools. Body mass index was calculated, and the concepts of overweight and obesity were defined according to the standard of the Working Group for Obesity in China.

RESULTS

Data indicated that 18.2% (95% CI: 16.5%-20.0%) of children and adolescents with ID were overweight and 14.4% (95% CI: 12.8%-16.0%) were obese. Boys with ID were more likely to be overweight than girls with ID (OR = 1.48[95% CI: 1.13-1.94], P < 0.05). Children and adolescents with Down syndrome or autism spectrum disorder had a trend to be classified as overweight (OR = 1.76[95% CI: 1.22-2.54], P < 0.05; OR = 1.57[95% CI: 1.17-2.09], P < 0.05, respectively) or obesity (OR = 1.82[95% CI: 1.23-2.69], P < 0.05; OR = 1.40 [95% CI: 1.02-1.93], P < 0.05, respectively) compared with those with ID without these conditions. Moreover, children and teenagers with ID living in urban areas had a predisposition to be overweight (OR = 2.16[95% CI: 1.14-4.09], P < 0.05) or obese (OR = 3.25[95% CI: 1.41-7.50], P < 0.05) relative to those who lived in rural areas.

CONCLUSION

Results indicated that in China, the prevalence rate of overweight and obesity among school-aged children and adolescents with ID was remarkably high. Therefore, future research should make every effort to focus on reducing and preventing overweight and obesity of this population in China.

Down Syndrome Is a Metabolic Disease: Altered Insulin Signaling Mediates Peripheral and Brain Dysfunctions

Down syndrome (DS) is the most frequent chromosomal abnormality that causes intellectual disability, resulting from the presence of an extra complete or segment of chromosome 21 (HSA21). In addition, trisomy of HSA21 contributes to altered energy metabolism that appears to be a strong determinant in the development of pathological phenotypes associated with DS. Alterations include, among others, mitochondrial defects, increased oxidative stress levels, impaired glucose, and lipid metabolism, finally resulting in reduced energy production and cellular dysfunctions. These molecular defects seem to account for a high incidence of metabolic disorders, i.e., diabetes and/or obesity, as well as a higher risk of developing Alzheimer’s disease (AD) in DS. A dysregulation of the insulin signaling with reduced downstream pathways represents a common pathophysiological aspect in the development of both peripheral and central alterations leading to diabetes/obesity and AD. This is further strengthened by evidence showing that the molecular mechanisms responsible for such alterations appear to be similar between peripheral organs and brain. Considering that DS subjects are at high risk to develop either peripheral or brain metabolic defects, this review will discuss current knowledge about the link between trisomy of HSA21 and defects of insulin and insulin-related pathways in DS. Drawing the molecular signature underlying these processes in DS is a key challenge to identify novel drug targets and set up new prevention strategies aimed to reduce the impact of metabolic disorders and cognitive decline.

Mental health, loss of control eating, and cognitive functioning in adolescents undergoing bariatric surgery

Bariatric surgery is an effective treatment for severe obesity in adolescence. Nevertheless, much remains to be understood regarding the impact of surgery on mental health, eating behaviors, and cognition. We review the findings related to mental health both before and after surgery as well as long-term changes in psychopathology, including suicide risk. Overall, adolescents with and without a history of psychopathology lose weight at similar rates. At the same time, there is an increased risk for suicide that requires further study. Regarding alcohol and substance use, this population reports lower rates of consumption than age related non-obese cohorts. Nevertheless the impact of altered anatomy and metabolism on alcohol ingestion in a population at risk for substance use is concerning. Eating behaviors, specifically loss of control eating, are discussed. Finally, we include discussion of the cognitive changes occurring perioperatively and considerations for adolescents with cognitive impairments. Clinical recommendations and suggestions for future research are discussed.

Prevalence and factors associated with overweight and obesity among Spanish students attending special education schools

BACKGROUND

Some studies suggest that children and adolescents with intellectual disability (ID) are at elevated risk of obesity. The objective was to determine the prevalence of and factors associated with overweight and obesity among students attending special education schools in Cantabria, Spain.

METHODS

Cross-sectional design. A sample of n = 220 students with intellectual disability attending seven special education schools was selected using convenience sampling. Body mass index was classified into four categories according to the International Obesity Task Force (IOTF) criteria: underweight; normal weight; overweight; obesity.

RESULTS

The prevalence of overweight/obesity was 40.9% (95% CI: 34.6-47.5). Obesity was more frequent among females (26.0%) than males (9.8%), with an OR = 3.23 (95% CI: 1.53-6.85). Participants with Down syndrome showed an increased risk of obesity compared to other conditions (p = .005).

CONCLUSIONS

The prevalence of overweight/obesity among children, adolescents and young adults with intellectual disability was remarkably high, with females in general and students of both sexes with Down syndrome at particularly high risk.

Sleeve Gastrectomy for Youth With Cognitive Impairment or Developmental Disability

BACKGROUND AND OBJECTIVES

Youth with cognitive impairment or developmental disability (CI/DD) face higher rates of obesity and secondary medical issues. Bariatric surgery may be a helpful tool for health improvement because it has been shown efficacious for adolescents. We aim to contribute to literature regarding bariatric surgery for adolescents with CI/DD and explore the association between cognitive functioning and weight loss outcomes.

METHODS

Adolescents (N = 64) received a preoperative psychological evaluation, including cognitive assessment, and bariatric surgery at 1 weight loss program between 2010 and 2017. For these adolescents with measured cognitive performance, CI/DD was defined by an IQ <80 or previous diagnosis. In analyses, we compared adolescents with and without CI/DD. Structural equation modeling was used to assess the impact of cognitive functioning on weight loss 3 to 24 months postsurgery.

RESULTS

There were no significant differences between adolescents with or without CI/DD in terms of preoperative BMI, age, and sex. Having CI/DD did not significantly impact weight loss or weight loss trajectory in the 2 years after surgery, although modeling revealed a trend toward individuals with CI/DD losing more weight over time. Similarly, intelligence scores did not predict weight loss after surgery.

CONCLUSIONS

Bariatric surgery may be a helpful tool for adolescents with severe obesity and CI/DD. They could benefit from the surgery as much as those with typical development, and having CI/DD should not be used as a criterion to deny surgery. Continuing research with this population can be used to determine long-term outcomes in addition to defining best practices.

Physical fitness of children and adolescents with moderate to severe intellectual disabilities

Background: Low levels of physical fitness are associated with low physical and mental health. The aims of this study were to assess the health-related physical fitness of children with intellectual disability (ID), and study the association of physical activity and motor development with physical fitness.Methods: One hundred and twenty-eight children with moderate to severe ID (83 boys; age 2-18 years) visiting specialised day programme centres engaged in field-based physical fitness tests (body composition, muscular strength, muscular endurance, and cardiorespiratory fitness). Scores were compared to reference values, and with linear regression analysis the association between the fitness outcomes and physical activity and motor development was studied.Results: High rates of overweight (23-25%) and obesity (10-15%) were found. A majority of the participants (71-91%) scored below reference values for muscular strength, endurance, and cardiorespiratory fitness tests. Physical activity and motor development were positively associated with scores on several fitness test (β = 0.27-0.44; p < 0.05).Conclusions: Children with moderate to severe ID visiting specialised day programme centres have strikingly low physical fitness levels. Policies and interventions to increase the physical fitness for this specific group of children are urgently needed, in which increasing physical activity and motor skills are expected to be effective components.Implications for rehabilitationStrikingly low levels of physical fitness were seen in children and adolescents with moderate to severe intellectual disabilities.This vulnerable group is in need of appropriate interventions to increase their physical fitness levels.Increasing the physical activity is a potential component in these interventions.Improving motor development will most likely lead to improved physical fitness as well.

Physical self-concept and body dissatisfaction among Special Olympics athletes: A comparison between sex, weight status, and culture

BACKGROUND

Little research has looked at the associations between sex, weight status and culture, and the physical self-perceptions and body dissatisfaction of individuals with intellectual disabilities (ID) involved in Special Olympics (SO) sports.

AIMS

To examine sex- (male vs female), weight status- (non-overweight/obese vs. overweight/obese), and culture-based (North American vs. Asian) differences in physical self-concept and body dissatisfaction among SO athletes.

METHODS AND PROCEDURES

A total of 139 SO athletes (aged 12-30 years) with ID participated in this study and completed measures of physical self-perceptions and body dissatisfaction. Differences according to sex, weight status, culture, and their interactions were examined.

OUTCOMES AND RESULTS

Males SO athletes presented higher levels of self-perceived physical strength and ideal body shape than females. Additionally, non-overweight/obese SO athletes presented higher levels of self-perceived physical appearance and physical condition than their overweight/obese counterparts, as well as lower actual body shape perceptions and body dissatisfaction. Moreover, North-American SO athletes presented higher levels of self-perceived physical appearance and sport competence than their Asians counterparts, as well as lower actual body shapes perceptions and body dissatisfaction.

CONCLUSION AND IMPLICATIONS

This study reveals substantial sex-, weight status-, and culture-based differences in the physical self-concept and body dissatisfaction of SO athletes.

Utilizing health records to characterize obesity, comorbidities, and health-care services in one human service agency in the United States

US surveys report higher prevalence of obesity in adults with intellectual disability. Health records of 40 adults with intellectual disability were retrospectively reviewed for data on health status, problem lists with International Classification of Diseases, Ninth Revision codes, medication lists, and health encounters over 18 months. Mean age was 49.5 years, 53% were males. Prevalence of overweight, obese, and morbidly obese was 28%, 58%, and 23%, respectively. Primary diagnosis was intellectual disability (50% mild, 33% moderate, 10% severe, and 8% profound), 85% had mental health disorders (67.5% with affective or mood and 42.5% had anxiety disorders). On average, residents consumed 2.63 psychotropic medications daily with additional 5.75 medications for axis 3 diagnoses and made 39.2 health visits over past 18 months. Our analysis supports increased prevalence of overweight/obesity, higher comorbidities, dual psychiatric diagnosis, substantial medication consumption, and higher utilization of health-care services in adults with intellectual disabilities. Targeted health interventions are therefore essential to improve their health and quality of life.

Prevalence of hypertension and prehypertension in children and adolescents with intellectual disability in southeastern Poland

BACKGROUND

There is insufficient information on the prevalence of hypertension (HPT) among children and adolescents with ID.

AIM

The aim of this study was to determine the prevalence of HPT in children and adolescents with ID in comparison with the control group, which accounted for children and adolescents without ID.

METHODS

The study included 568 students with ID, aged from 7 to 18, attending special education institutions in southeastern Poland. The control group consisted of 568 students (matched to the study group for age and gender) without ID, attending randomly selected elementary and secondary schools located in the same area. Blood pressure was measured in compliance with the European Society of Hypertension recommendations.

RESULTS

The overall prevalence of HPT and pre-HPT in children and adolescents with ID were 18.5 and 20.6% respectively. Prevalence of HPT and pre-HPT in children and adolescents without ID were 5.8 and 18.5% respectively. Children and adolescents with a higher level of ID were found to be at a greater risk of HPT. An excessive body mass and older age were predisposing factors to a significantly higher prevalence of HPT in children and adolescents with ID.

CONCLUSION

The prevalence of HPT among students with ID was more than three times higher than in the general population. The level of ID, age, sex and body mass significantly correlated with HPT in the study group.

Treatment of Obesity Among Youth With Intellectual and Developmental Disabilities: An Emerging Role for Telenursing

Childhood obesity is a serious health issue, associated with medical comorbidity and psychosocial impairment that can persist into adulthood. In the United States, youth with intellectual and developmental disabilities are more likely to be obese than youth without disabilities. A large body of evidence supports the efficacy of family-based treatment of childhood obesity, including diet, physical activity, and behavior modification, but few interventions have been developed and evaluated specifically for this population. We highlight studies on treatment of obesity among youth with intellectual and developmental disabilities, including both residential/educational settings as well as outpatient/hospital settings. All interventions were delivered in-person, and further development of promising approaches and delivery via telenursing may increase access by youth and families. Nursing scientists can assume an important role in overcoming barriers to care for this vulnerable and underserved population.

Overweight and obesity among children at risk of intellectual disability in 20 low and middle income countries

BACKGROUND

Children with intellectual disability (ID) in high income countries are at significantly greater risk of obesity than their non-disabled peers. We aimed to estimate the prevalence of overweight and obesity in 3 to 4-year-old children who are/are not at risk of ID in low and middle income countries.

METHOD

Secondary analysis of Round 4 and 5 UNICEF Multiple Indicator Cluster Surveys (MICS) from 20 low and middle income countries that included a total of 83 597 3 to 4-year-old children.

RESULTS

Few differences in risk of overweight or obesity were apparent between 3 and 4-year-old children identified as being at risk/not at risk of ID in 20 low and middle income countries. In the two countries where statistically significant differences were observed, prevalence of overweight/obesity was lower among children at risk of ID.

CONCLUSIONS

These results stand in stark contrast to evidence from high income countries which suggest that children with ID are at significantly increased risk of obesity when compared to their non-intellectually disabled peers.

Obesity in British children with and without intellectual disability: cohort study

Background

Reducing the prevalence of and inequities in the distribution of child obesity will require developing interventions that are sensitive to the situation of ‘high risk’ groups of children. Children with intellectual disability appear to be one such group. We aimed to estimate the prevalence of obesity in children with and without intellectual disability in a longitudinal representative sample of British children and identify risk factors associated with obesity at age 11.

Methods

Information was collected on a nationally representative sample of over 18,000 at ages 9 months, 3, 5, 7 and 11 years. We used UK 1990 gender-specific growth reference charts and the LMS Growth programme to identify age and gender-specific overweight and obesity BMI thresholds for each child at ages 5, 7 and 11 years.

Results

Children with intellectual disabilities were significantly more likely than other children to be obese at ages five (OR = 1.32[1.03–1.68]), seven (OR = 1.39[1.05–1.83]) and eleven (OR = 1.68[1.39–2.03]). At ages five and seven increased risk of obesity among children with intellectual disabilities was only apparent among boys. Among children with intellectual disability risk of obesity at age eleven was associated with persistent maternal obesity, maternal education, child ethnicity and being bullied at age five.

Conclusions

Children with intellectual disability are a high-risk group for the development of obesity, accounting for 5–6 % of all obese children. Interventions to reduce the prevalence and inequities in the distribution of child obesity will need to take account of the specific situation of this group of children.

Prevalence of overweight and obesity among students with intellectual disabilities in Taiwan: A secondary analysis

PURPOSE

The study aims to investigate the prevalence and likelihood of overweight and obesity in a large sample of students with intellectual disabilities (ID) from Taiwan.

METHOD

A secondary analysis of a cross sectional study was employed to examine the body weight status among 7 to 18 year-old students with ID enrolled in public special education schools in 2013. The students were divided into three age groups (7-12 yrs, 13-15 yrs, and 16-18 yrs), four ID levels (mild, moderate, severe, and profound) and six comorbidities of ID (ID only, ID caused by genetic disorders, ID with physical disability, ID with multiple disabilities without physical disabilities, ID with autism spectrum disorders, and others with rare diseases).

RESULTS

The sample represented 34.8% of students with ID attending public special education schools in Taiwan. Within this sample, 35.2% were identified as being overweight or obese. The 16 to 18 year-old age group were approximately two times (AOR=2.02, more likely to be obese than the 7-12 year-old group. Students with ID caused by genetic disorders such as Down syndrome (AOR=2.00) appeared to be more overweight or obese in comparison to those with ID only. Students with moderate (AOR=1.64) and severe ID (AOR=1.49) were more overweight/obese compared to those with profound ID.

CONCLUSION

The findings not only highlight the high prevalence of overweight/obesity but also stress the need for health promotion initiatives to address issues of overweight/obesity within this population.

Intellectual Disabilities Among Prisoners: Prevalence and Mental and Physical Health Comorbidities

BACKGROUND

Limited evidence suggests that people with ID (ID) are overrepresented in prisons although prevalence rates of ID among prisoners vary significantly across studies, making it difficult to identify prevalence and assess existing need.

METHOD

A systematic review of relevant literature was conducted, and results were organized and compared in relation to study aims, design, measures used to screen for ID, sample, limitations and key findings.

RESULTS

Existing international data suggest a prevalence of prisoners with ID between 7 and 10%. Most frequent coexisting health issues among this population are hearing and vision impairments, obesity, diabetes and a range of mental health disorders, notably anxiety and personality and conduct disorders.

CONCLUSION

More research is required on prevalence rates and associated comorbidities of ID within prison settings, taking into account the heterogeneity of the population with ID.

Possible association between moderate intellectual disability and weight gain in valproic acid-treated patients with epilepsy

BACKGROUND

Although patients with moderate intellectual disability (ID) are known to have higher rates of being overweight and obese than those without ID, there are no current data regarding the relationship between ID and weight gain in epilepsy patients treated with valproic acid (VPA).

PATIENTS AND METHODS

The possible association between moderate ID and an overweight status at the time of initiation of VPA therapy (baseline) was investigated using a logistic regression analysis in 143 patients with epilepsy. Among the 119 nonoverweight patients at baseline, the longitudinal association between moderate ID and the weight status during VPA therapy was retrospectively examined using a Cox hazards regression analysis and the generalized estimating equations approach, while also paying careful attention to associations with other patient characteristics.

RESULTS

The proportion of patients with moderate ID was 52.4% among the 143 study subjects. The presence of moderate ID was not associated with an overweight status at baseline (P=0.762). Among the nonoverweight patients at baseline, 16 subjects were newly diagnosed as being overweight during treatment with VPA (3.6±2.1 years). The presence of moderate ID was significantly associated with the incidence of an overweight status after starting VPA therapy (adjusted hazard ratio =6.72, P=0.007). The patient age at baseline and treatment with co-administered carbamazepine, clobazam, and zonisamide significantly influenced the degree of weight fluctuation during VPA therapy among the patients with moderate ID (P<0.001, P<0.001, P=0.002, and P=0.028, respectively), whereas only patient age at baseline affected this parameter among the patients without moderate ID (P=0.022).

CONCLUSION

The present findings suggest that the weight status should be carefully monitored in VPA-treated patients with moderate ID, especially those receiving other co-administered antiepileptic drugs that facilitate weight gain, such as carbamazepine.

The use of technology for delivering a weight loss program for adolescents with intellectual and developmental disabilities

Adolescents with intellectual and developmental disabilities (IDD) are at an increased risk of obesity, with up to 55% considered overweight and 31% obese. However, there has been minimal research on weight management strategies for adolescents with IDD. The purpose of this study was to compare the effectiveness of two weight loss diets, an enhanced Stop Light Diet (eSLD) and a conventional diet (CD), and to determine the feasibility of using tablet computers as a weight loss tool in overweight and obese adolescents with IDD. A 2-month pilot intervention was conducted. All participants were randomized to the eSLD or CD and were given a tablet computer that they used to track daily dietary intake and physical activity. Participants and parents met weekly with a registered dietitian nutritionist via video chat on the tablet computer to receive diet and physical activity feedback and education. Twenty participants (45% female, aged 14.9±2.2 years) were randomized and completed the intervention. Participants in both diets were able to lose weight, and there were no significant differences between the eSLD and CD (-3.89±2.66 kg vs -2.22±1.37 kg). Participants were able to use the tablet computer to track their dietary intake 83.4%±21.3% of possible days and to attend 80.0% of the video chat meetings. Both dietary interventions appear to promote weight loss in adolescents with IDD, and the use of tablet computers appears to be a feasible tool to deliver a weight loss intervention in adolescents with IDD.

Obesity and health behaviours of British adults with self-reported intellectual impairments: cross sectional survey

BACKGROUND

People with intellectual disability have significantly higher age-adjusted rates of mortality and morbidity (including obesity) than their non-disabled peers. They are also significantly less likely to be physically active.

METHODS

Secondary analysis of de-identified cross-sectional data from the first two waves of Understanding Society, a new longitudinal study focusing on the life experiences of UK citizens. Interviews were undertaken with 50,994 individuals aged 16 and over in Wave 1 and 54,585 in Wave 2. Of these, 520 participants age 16-49 (1.8% of the unweighted age-restricted sample) were identified at either Wave 1 or Wave 2 as having self-reported intellectual impairments.

RESULTS

British adults with self-reported intellectual impairments have higher rates of obesity, inactivity, tobacco and alcohol use and poorer nutrition than their non-disabled peers. Adjusting risk estimates for between group differences in age, gender and exposure to material hardship indicated that a significant proportion of their increased risk of obesity, tobacco use and poorer nutrition may be attributable to their poorer living conditions (rather than their self-reported intellectual impairments per se).

CONCLUSIONS

People with intellectual disabilities should begin to be regarded as a 'vulnerable' group in the context of public health policy and practice.

The prevalence and determinants of overweight and obesity among French youths and adults with intellectual disabilities attending special education schools

This study examines the prevalence of overweight and obesity and a panel of potential determinants among French youths and adults with an intellectual disability (ID). The sample used consisted of 1120 youths and adults with an ID, from 5 to 28 years old, attending a French special education school. The results indicated that 19.8% of the participants with an ID are classified as overweight and 8.6% as obese. Multivariate logistic regression analyses revealed that there are nearly three times more girls/women classified as overweight than boys/men. Additionally, they showed that there are nearly two times more participants from southern France classified as overweight than from northern France, and that the risk of being classified as overweight significantly increases with seniority in the school. Next, the interaction effects observed indicated first that there are nearly two times more boys/men on psychotropic medication classified as overweight than boys/men not on psychotropic medication. Second, they revealed that the odds of being classified as overweight for boys/men not on psychotropic medication are 47% lower than for girls/women not on psychotropic medication. Third, they indicated that there are nearly two times more boys/men from southern France classified as obese than boys/men from northern France. Fourth, they showed that the odds of being classified as obese for boys/men from northern France are 52% lower than for girls/women from northern France. In conclusion, these results should be viewed as preliminary and need to be replicated since, to our knowledge, this study is the first one to examine this topic while simultaneously controlling for all of the potential determinants and relying on a sample of youths and adults.
