Eating behaviors and weight over time in a prospective study: the Healthy Twin Study

We examined the relationships of combined initial restrained and external/emotional eating with initial BMI andchange in weight and these subscales over time. BMI and the Dutch Eating Behavior Questionnaire were twicemeasuredin 1361 Korean twins and families (482 men, 879 women) over a period of 2.7±0.9 years. Subjectswere classified by combination of initial sex-specific restrained and external (or emotional) eating tertiles. Linearmixed models were performed after adjusting for confounders at baseline (household, sibling relations, sex, age,education level, smoking, alcohol use, energy intake, physical activity, and medical history). In adjusted models,initial BMI increased with increasing tertiles of initial restrained eating across initial external/emotional eatingtertiles. Weight was less likely to increase over time with increasing tertiles of initial restrained eating in the lowestexternal eating tertile and middle tertile of emotional eating at baseline. Subscale scores decreased over timewith increasing tertiles of corresponding subscales at baseline. These findings suggest that high dietary restraintand external/emotional eating may indicate concurrent high BMI and attenuated weight gain and decreases in correspondingsubscales over time.This work was supported by the 2013 Inje University research grant.OAIID:oai:osos.snu.ac.kr:snu2014-01/102/0000040632/2SEQ:2PERF_CD:SNU2014-01EVAL_ITEM_CD:102USER_ID:0000040632ADJUST_YN:NEMP_ID:A077602DEPT_CD:902CITE_RATE:1.055FILENAME:2.eating behaviors and weight over time in a prospective_인제대.pdfDEPT_NM:보건학과EMAIL:jsung@snu.ac.krSCOPUS_YN:YCONFIRM:
