The Effect of a Medium-Term Activity- and Diet-Induced Energy Deficit on Subjective Appetite Sensations in Obese Children
Description
Objective: To assess the subjective appetite responses to an imposed activity- and diet-induced energy deficit during a residential intervention programme for obese children. Design: A 6-week intervention of fixed, reduced dietary intake and 6 h/day of skill-based physical activity while resident in a weight loss camp. Subjects: Thirty-eight obese (mean body mass index (BMI)=34.9 kg m-2) boys and girls (mean age 13.9 1.57). Measurements: An electronic appetite rating system (EARS) was used to periodically measure subjective appetite sensations at the start (WK1) and at the end (WK6) of the camp. Subjective ratings of hunger and fullness were compared at the start and end of 6 weeks of an activity- and diet-induced-based weight loss intervention. Results: At the end of the 6 weeks, the children had lost 8.4 kg in body mass. The diurnal profiles of subjective appetite sensations demonstrated clear oscillations in hunger and fullness. There was a significant increase in hunger (P<0.0001) and decrease in fullness (P<0.005) at the end (WK6) of the medium-term energy deficit. In WK6, morning ratings of hunger were higher than in WK1 (P<0.005) and the fixed energy evening meal induced a lower suppression of hunger (P<0.02). Conclusion: A programme of fixed, reduced-dietary intake combined with an activity and behavioural programme was successful at inducing a significant reduction in body mass in obese children. Subjective sensations of appetite were sensitive to a medium-term negative energy balance and weight loss. These data are essential as we continue to evolve methods of treatment for overweight and obese children.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
