Abstract

OBJECTIVE. To examine the effect of adenotonsillectomy (T&A) in children with obstructive sleep-disordered breathing on growth, hyperactivity, and sleep and waking motor activity. METHODS. We studied 54 children who were aged 6 to 12 years and had adenotonsillar hypertrophy and an obstructive apnea-hypopnea index of [greater than or equal to] 1 before and 12 months after they all received adenotonsillectomy (T&A). We measured their height, weight, percentage overweight (patient BMI--BMI at 50th percentile)/BMI at 50th percentile * I00) and obtained a hyperactivity score from parent report on a standardized behavior questionnaire scale. A subset of 21 of these children were also studied for motor activity by wrist actigraphy for 7 consecutive days and nights before and 12 months after T&A. RESULTS. After T&A, mean obstructive apnea-hypopnea index decreased from 7.6 to 0.6. Height percentile did not change, but weight percentile increased; as a consequence, percentage overweight increased from 32.0% to 36.3%. Hyperactivity scores and total daily motor activity were reduced after T&A. From linear regression, the reduction in hyperactivity scores predicted an increase in percentage overweight. Reduced motor activity was correlated with increased percentage overweight. CONCLUSIONS. An increase in percentage overweight after T&A in children with obstructive sleep-disordered breathing is correlated to decreased child hyperactivity scores and to decreased measured motor activity in the subset studied. These associations suggest that the increase in overweight may be attributable to reductions in physical activity and fidgeting energy expenditure.

Abstract

Objective: The interaction of food reinforcement and the inability to delay gratification are related to adult energy intake and obesity. This study was designed to test the association of sibling pair differences in relative reinforcing efficacy of food and delay discounting on sibling pair differences in zBMI scores of same-gender zBMI-discordant siblings. Design and methods: We tested main and interactive relationships between delay discounting and relative reinforcing efficacy of food on zBMI discordance in 14 zBMI-discordant biological sibling pairs (6 female pairs) using a discordant sibling study design. Results: Sibling pair differences in relative reinforcing efficacy of food were associated with sibling pair differences in zBMI ( p   =  0.046); this effect was moderated by delay discounting ( p  <   0.002). Sibling pairs with greater differences in relative reinforcing efficacy and delay discounting had greater differences in zBMI. Conclusions: The combination of greater sibling pair differences in delay discounting and relative reinforcing efficacy is associated with greater discordance in zBMI in adolescent sibling pairs.

Abstract

Objective: Similar to parks, college campuses may promote physical activity. The purpose of this study was to compare the physical activity of adults at urban campuses and parks.Participants: Participants were individuals observed on campuses and parks in April 2011.Methods: The System for Observing Play and Recreation in Communities was used to assess physical activity at 3 campuses and parks, 3 times/day, for 4 days.Results: Greater proportions of individuals (parks, campuses) were observed in vigorous (28.7%, 11.9%) and sedentary (25%, 18.3%) activities at parks than campuses and a greater proportion observed in walking (69.8%, 46.3%) intensity on campuses than parks. More men than women were observed at both parks and campuses, and paths and sport courts were most frequently used for physical activity.Conclusions: Physical activity intensities differ across college campuses and parks that provided similar physical activity amenities. Efforts should focus on increasing awareness of outdoor campus amenities that promote physical activity and understanding the outdoor amenities that of promote physical activity of women.

250. Stress, Behavior, and Biology: Risk Factors for Cardiovascular Diseases in Youth.

Author

Lambiase, Maya J., Balantekin, Katherine N., Feda, Denise M., Roemmich, James N., and Dorn, Joan

Abstract

Psychological stress reactivity is associated with atherogenesis in youth. The novel hypothesis is that stress promotes atherogenic behaviors, including snacking on energy-dense food and reducing physical activity, and increases adiposity. Stress also increases systolic blood pressure cardiovascular reactivity, which also may be atherogenic. Exercise dampens stress reactivity and may be one mechanism by which it protects against the development of cardiovascular diseases. [ABSTRACT FROM AUTHOR]
