OBJECTIVES : To determine whether reduced sleep is associated with differences in body composition and the risk of becoming overweight in young children.<\/p>\n

DESIGN:Longitudinal study with repeated annual measurements.<\/p>\n

SETTING:Dunedin, New Zealand.<\/p>\n

PARTICIPANTS: 244 children recruited from a birth cohort and followed from age 3 to 7.<\/p>\n

MAIN OUTCOME MEASURES: Body mass index (BMI), fat mass (kg), and fat free mass (kg) measured with bioelectrical impedance; dual energy x ray absorptiometry; physical activity and sleep duration measured with accelerometry; dietary intake (fruit and vegetables, non-core foods), television viewing, and family factors (maternal BMI and education, birth weight, smoking during pregnancy) measured with questionnaire.<\/p>\n

RESULTS: After adjustment for multiple confounders, each additional hour of sleep at ages 3-5 was associated with a reduction in BMI of 0.48 (95% confidence interval 0.01 to 0.96) and a reduced risk of being overweight (BMI ≥ 85th centile) of 0.39 (0.24 to 0.63) at age 7. Further adjustment for BMI at age 3 strengthened these relations. These differences in BMI were explained by differences in fat mass index (-0.43, -0.82 to -0.03) more than by differences in fat free mass index (-0.21, -0.41 to -0.00).<\/p>\n

CONCLUSIONS:Young children who do not get enough sleep are at increased risk of becoming overweight, even after adjustment for initial weight status and multiple confounding factors. This weight gain is a result of increased fat deposition in both sexes rather than additional accumulation of fat free mass.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-38820","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Women's and Children's Health, University of Otago, Dunedin, New Zealand.","annee":"2011","mois":"5","numero":"","page":"","auteurs":[{"ID":25001,"post_author":"0","post_date":"2018-12-03 22:09:01","post_date_gmt":"2018-12-03 21:09:01","post_content":"","post_title":"Sheila M Williams","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sheila-m-williams","to_ping":"","pinged":"","post_modified":"2018-12-03 22:09:01","post_modified_gmt":"2018-12-03 21:09:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sheila-m-williams\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38819,"post_author":"0","post_date":"2018-12-04 01:43:37","post_date_gmt":"2018-12-04 00:43:37","post_content":"","post_title":"Carter","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"carter-3","to_ping":"","pinged":"","post_modified":"2018-12-04 01:43:37","post_modified_gmt":"2018-12-04 00:43:37","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/carter-3\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":2589,"post_author":"0","post_date":"2018-12-03 16:57:10","post_date_gmt":"2018-12-03 15:57:10","post_content":"","post_title":"Barry J Taylor","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"barry-j-taylor","to_ping":"","pinged":"","post_modified":"2018-12-03 16:57:10","post_modified_gmt":"2018-12-03 15:57:10","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/barry-j-taylor\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":2587,"post_author":"0","post_date":"2018-12-03 16:57:09","post_date_gmt":"2018-12-03 15:57:09","post_content":"","post_title":"Rachael W Taylor","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"rachael-w-taylor","to_ping":"","pinged":"","post_modified":"2018-12-03 16:57:09","post_modified_gmt":"2018-12-03 15:57:09","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/rachael-w-taylor\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":24550,"post_author":"0","post_date":"2018-12-03 21:56:30","post_date_gmt":"2018-12-03 20:56:30","post_content":"","post_title":"BMJ","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bmj","to_ping":"","pinged":"","post_modified":"2018-12-03 21:56:30","post_modified_gmt":"2018-12-03 20:56:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/bmj\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nLongitudinal analysis of sleep in relation to bmi and body fat in children: the flame study. -
