Dysfunctional Eating Patterns of Adults With Attention Deficit Hyperactivity Disorder

Food Perceptions in Adults with and without ADHD

INTRODUCTION

Adults with attention-deficit/hyperactivity disorder (ADHD) have unhealthy eating habits, associated with overweight/obesity. We explored whether they present with different food-related benefit/risk perceptions, compared to those without ADHD.

METHODS

One hundred five university students with (n = 36) and without (n = 69) ADHD, aged 22-30, participated in the study. They rated the level of frequency and likelihood of food consumption, as well as the perceived attractiveness, convenience, and risk of 32 healthy and unhealthy food items.

RESULTS

The findings revealed significantly lower healthy/unhealthy food frequency consumption ratios for the ADHD group compared with the non-ADHD one but no differences in the ratios of estimated likelihood of food consumption and perceptions (attractiveness, convenience, and risk).

CONCLUSION

The results of this study demonstrated a discrepancy between the eating behavior (more unhealthy eating patterns in adults with ADHD compared with controls) and their food-related perceptions (same perceptions regarding the benefit and risk of foods in both groups).

Longitudinal Associations Between Symptoms of ADHD and BMI From Late Childhood to Early Adulthood

BACKGROUND AND OBJECTIVES

Attention-deficit/hyperactivity disorder (ADHD) and obesity are 2 frequent conditions that co-occur, which has implications for the management of both conditions. We hypothesized that ADHD symptoms predict BMI and vice versa from late childhood (10-12 years) up to early adulthood (20-22 years).

METHODS

Participants were adolescents in the Netherlands (n = 2773, 52.5% male, mean age = 11 years at baseline, 5 waves up to mean age 22) from the Tracking Adolescents' Individual Lives Survey cohort. We examined bidirectional relationship between ADHD symptoms (hyperactivity/impulsivity and inattention) and BMI using the random intercept cross-lagged panel model. Time-varying covariates were pubertal status, stimulant use, depressive symptoms, and family functioning, and socioeconomic status was a time-invariant covariate.

RESULTS

We found a time-invariant association of BMI with hyperactivity and impulsivity, but not with inattention, which was slightly stronger in female adolescents (female: r = 0.102; male: r = 0.086, P < .05). No longitudinal direct effects were found between ADHD symptoms and BMI during this period.

CONCLUSIONS

Over the course of adolescence, the link between ADHD and BMI is stable and is predominantly with hyperactive and impulsive symptoms rather than inattention. There was no direct effect of ADHD symptoms on BMI increase nor of BMI on enhanced ADHD symptoms during this developmental period. The findings point to a shared genetic or familial background and/or potential causal effects established already earlier in childhood, thus suggesting that intervention and prevention programs targeting overweight and obesity in children with ADHD should be implemented in early childhood.

Advertising Influences Food Choices of University Students With ADHD

Objective: Previous research in adults with ADHD showed high rates of obesity and unhealthy food choices. There is evidence that contextual cues, for example, advertisements, influence food choices. This study assessed the sensitivity of university students with ADHD to advertised food. Method: University students (N = 457) with and without ADHD participated in a cafeteria field experiment. Food choices were examined in periods of advertising either healthy or unhealthy sandwiches. Results: Students with ADHD (a) chose less healthy food items, (b) were more influenced by advertising, (c) showed the same overall healthy food choices as controls when exposed to healthy advertising. Conclusion: Students with ADHD chose unhealthier foods at the cafeteria but were also more influenced by advertising. Healthy food advertisements raised their healthy food choices. As this population has strong association with unhealthy dietary patterns, it is important to investigate the influence of food cues on their eating habits.

The influence of attractiveness and convenience cues on food appeal in adults with and without ADHD

OBJECTIVE

Previous research on adults with ADHD revealed high rates of overweight and obesity, as well as unhealthy diet habits. Other studies demonstrated that social-affective contexts can influence food choice. This study examines the sensitivity of adults with ADHD to cues of food attractiveness and convenience, for healthy and unhealthy foods.

METHOD

One hundred and seventy-two university students with (n = 59) and without (n = 113) ADHD, aged 19-40, participated in the study. Participants rated the level of appeal of 32 pictures of healthy and unhealthy foods, which varied in the degree of attractiveness and convenience.

RESULTS

The findings reveal a higher level of appeal of attractive food items compared to non-attractive ones (p < .001), as well as of convenient compared to non-convenient food items (p = .005). Type of diagnostic group did not have an effect on the level of appeal.

CONCLUSION

Increasing the attractiveness and convenience of food items increased the level of appeal for both students with and without ADHD. These findings emphasize the importance of environmental health intervention to potentially reduce abnormal eating pattern in the ADHD adult population, which may contribute in preventing the reported higher risk of obesity in this population.

Children With Attention-Deficit/Hyperactivity Disorder Are at Increased Risk for Slowed Growth and Short Stature in Early Childhood

Our objective was to evaluate the risk of short stature in children with attention-deficit/hyperactivity disorder (ADHD) and the effect of ADHD and its treatment on height-for-age z score (HAZ) and body mass index-for-age z score (BMIZ) in early childhood. We evaluated 7603 children from the Early Childhood Longitudinal Study-Kindergarten Cohort 2011 and found that children with ADHD had lower HAZ at second and fourth grades and lower BMIZ at K to fourth grade. Children with ADHD at fourth grade had almost 4 times higher odds of short stature. Children with ADHD at K grew at a slower rate from K to fourth grade (difference in ΔHAZ = 0.23, 95% confidence interval = 0.04-0.42) and had less gain in BMI (difference in ΔBMIZ = 0.16, 95% confidence interval = 0.03-0.29). Longer duration of ADHD medication use was associated with lower HAZ at fourth grade and slower growth from K to fourth grade. These data may assist pediatricians in considering risk of poor growth in children with ADHD.

Risk-Taking Behavior in Attention Deficit/Hyperactivity Disorder (ADHD): a Review of Potential Underlying Mechanisms and of Interventions

PURPOSE OF REVIEW

Attention deficit/hyperactivity disorder (ADHD) is associated with several forms of risk-taking behavior (RTB). This paper aims to examine the scope of ADHD-related RTB, to highlight potential underlying mechanisms of this association, and to review initial evidence for interventions aimed to treat ADHD-related RTB.

RECENT FINDINGS

Multiple lines of evidence indicate that ADHD is associated with real-life RTB across several domains (e.g., reckless driving, substance use, and unprotected sex), which is corroborated by evidence on laboratory risk-taking tasks. Several individual differences, some of them informed by decision theory, e.g., comorbid disorders, parental monitoring, and perceived enlarged benefits of RTB, may explain the link between ADHD and RTB. A number of studies showed that interventions designed for ADHD may reduce RTB. ADHD is linked to RTB across several domains. Decision theory may serve as a conceptual framework for understanding the underlying mechanisms, and thus may inform future research.
