Determine whether obstructive sleep apnea (OSA) is associated with the dietary choices of obese individuals during middle- to late-childhood. It was hypothesized that OSA would be associated with increased caloric content of a dinner order, particularly with high carbohydrate food choices. Secondarily, we examined the relationships between sleep duration and dietary choices.
42 obese subjects aged 10-16.9 years participated in a cross-sectional study that involved systematic collection of sleep duration (based on actigraphy), presence and severity of obstructive sleep apnea (obstructive apnea+hypopnea index [AHI] from inpatient polysomnography) and the macronutrient content of dinners ordered from a standardized hospital menu the evening before the polysomnogram.
Primary analyses using Spearman rank-order correlations found that AHI was significantly associated with total calories, as well as grams of fat and carbohydrate, but not protein. These macronutrient variables did not correlate with sleep duration across a week, nor the night before the meal. Findings were unchanged after correcting for age- and sex-adjusted BMI.
More severe OSA appears to be associated with an increased preference for calorie-dense foods that are high in fat and carbohydrates in a manner that is independent of degree of obesity. Although this novel finding awaits replication, it has potential implications for the clinical care of obese youth and individuals with OSA, adds to the limited data that relate sleep to dietary choices and may have implications for OSA-related morbidity.

ABSTRACT: Decreased sleep duration and quality is associated with an increase in body weight and adiposity. Insomnia, obstructive sleep apnea, and restless legs syndrome are three of the most prevalent types of sleep disorder that lead to an increased risk for numerous chronic health conditions. Various studies have examined the impact of these sleep disorders on obesity, and are an important link in understanding the relationship between sleep disorders and chronic disease. Physical activity and exercise are important prognostic tools in obesity and chronic disease, and numerous studies have explored the relationship between obesity, sleep disorders, and exercise. As such, this review will examine the relationship between sleep disorders and obesity. In addition, how sleep disorders may impact the exercise response and how exercise may impact patient outcomes with regard to sleep disorders will also be reviewed.

ABSTRACT: Obesity is a significant risk factor in the pathogenesis of obstructive sleep apnoea (OSA) altering airway anatomy and collapsibility, and respiratory control. The association between obesity and OSA has led to an increasing focus on the role of weight loss as a potential treatment for OSA. To date, most discussion of obesity and OSA assumes a one-way cause and effect relationship, with obesity contributing to the pathogenesis of OSA. However, OSA itself may contribute to the development of obesity. OSA has a potential role in the development and reinforcement of obesity via changes to energy expenditure during sleep and wake periods, dietary habits, the neurohormonal mechanisms that control satiety and hunger, and sleep duration arising from fragmented sleep. Thus, there is emerging evidence that OSA itself feeds back into a complex mechanism that leads either to the development or reinforcement of the obese state. Whilst current evidence does not confirm that treatment of OSA directly influences weight loss, it does suggest that the potential role OSA plays in obesity and weight loss deserves further research.
