Genetic influences on disordered eating behaviour are largely independent of body mass index

Body image and self-perception about weight, irrespective of their actual body mass index, may predispose young females to disordered eating behaviour. A study was conducted to determine body image disturbance, weight perception and body mass index among female college students in Delhi having normal and disordered eating behaviours. The study sample comprised 734 female under-graduate students between 18-21 years from women’s colleges of Delhi University. An interview-cum-questionnaire schedule was used to assess the general profile of subjects and perceptions about their body weight. Adapted Eating Attitudes Test (EAT)-26 and Body Shape Questionnaire (BSQ)-8c was used to determine disordered eating behaviour and body image disturbance among the subjects respectively. Body Mass Index of the subjects was also computed. Findings revealed a significant difference in self-perception about body weight among subjects showing normal and disordered eating behaviours. Higher percentage of subjects from disordered eating group perceived themselves to be either overweight or obese as compared to subjects from normal eating behaviour group.Significantly higher BSQ-8c scores and Body Mass Index were also observed among subjects having disordered eating behaviour. The study indicated that poor body image, self-perception about body weight being high as well as high body mass index played a significant role in occurrence of disordered eating behaviour among female college students in Delhi.The study depicted the urgent need to have appropriate health and nutrition education programmes for female college students to improve their perceptions about body shape and weight to further prevent the occurrence of disordered eating behaviour among them and make them less vulnerable to consequent nutritional problems.

Polygenic Scores

Background: Disordered eating (DE) is common and is associated with body mass index (BMI). We investigated whether genetic variants for BMI were associated with DE. Methods: BMI polygenic scores (PGS) were calculated for participants of the Avon Longitudinal Study of Parents and Children (ALSPAC; N = 8654) and their association with DE tested. Data on DE behaviors (e.g., binge eating and compensatory behaviors) were collected at ages 14, 16, 18 years, and DE cognitions (e.g., body dissatisfaction) at 14 years. Mediation analyses determined whether BMI mediated the association between the BMI-PGS and DE. Results: The BMI-PGS was positively associated with fasting (OR = 1.42, 95% CI = 1.25, 1.61), binge eating (OR = 1.28, 95% CI = 1.12, 1.46), purging (OR = 1.20, 95% CI = 1.02, 1.42), body dissatisfaction (Beta = 0.99, 95% CI = 0.77, 1.22), restrained eating (Beta = 0.14, 95% CI = 0.10, 1.17), emotional eating (Beta = 0.21, 95% CI = 0.052, 0.38), and negatively associated with thin ideal internalization (Beta = −0.15, 95% CI = −0.23, −0.07) and external eating (Beta = −0.19, 95% CI = −0.30, −0.09). These associations were mainly mediated by BMI. Conclusions: Genetic variants associated with BMI are also associated with DE. This association was mediated through BMI suggesting that weight potentially sits on the pathway from genetic liability to DE.
