Relationships among weight stigma, eating behaviors and stress in adolescents in Wuhan, China.

ABSTRACT: Background:The purpose of this study was to examine the relationships among weight stigma, eating behaviors, and stress, as well as to analyze the effect of stress in mediating the association between weight stigma and eating behaviors. Methods:The study involved 1818 adolescents between 14 to 19?years of age and was conducted in Wuhan, China in 2019. Weight stigma, eating behaviors (cognitive restraint, uncontrolled eating, and emotional eating), and stress were assessed by self-report questionnaires. Hierarchical linear regression analyses were used to examine the predictors of cognitive restraint, uncontrolled eating, and emotional eating; the serial mediation models analyses were conducted to analyze the effect of stress in mediating the association between weight stigma and eating behaviors for the whole non-overweight (normal and underweight) and overweight or obese participants, respectively. Results:Hierarchical linear regression analyses showed that experiences of weight stigma significantly predicted uncontrolled eating and emotional eating regardless of body mass index (BMI) (non-overweight adolescents: uncontrolled eating: ? [SE]?=?0.161 [0.017]; emotional eating: ? [SE]?=?0.199 [0.008], p?

Project description:BackgroundWeight stigma is pervasive across the U.S. and is associated with poor health outcomes including all-cause mortality. One potential reason that weight stigma may be detrimental to health is that it begets poorer health behaviors. Therefore, the present study tested for associations between weight stigma and four health behaviors (i.e., eating behavior, alcohol use, sleep disturbance, and physical activity), while controlling for BMI and other potential confounds.Subjects/methodsParticipants (N = 2022) in the U.S. were recruited for the Eating in America Study using a Qualtrics panel between December 2019 and January 2020 and were census-matched according to national quotas for age, gender, income, race/ethnicity, and census region. Participants completed questionnaires about weight stigma, health behaviors, demographics, and anthropometric measurements. The current study employed a two-stage investigation: exploratory analyses were first performed on a random sample of the dataset (n = 438), then the remaining unexamined data were used to conduct confirmatory analyses that were preregistered on the Open Science Framework.ResultsControlling for BMI, weight stigma was significantly associated with greater disordered eating (b = 0.34, 95% CI [0.31, 0.38], p < 0.001), comfort eating (b = 0.32, 95% CI [0.25, 0.39], p < 0.001), sleep disturbance (b = 0.27, 95% CI [0.20, 0.33], p < 0.001), and alcohol use (b = 0.30, 95% CI [0.11, 0.49], p = 0.002), but not lower physical activity (b = -0.04, 95% CI [-0.13, 0.05], p = 0.402) for individuals across the weight spectrum. BMI and perceived weight status significantly moderated the effects of weight stigma on disordered eating and alcohol use. No gender differences were found. These confirmatory analyses partially replicated the exploratory stage 1 findings.ConclusionsThis study provides preliminary evidence that weight stigma is linked to several poor health behaviors, which may impact physical health.

Project description:ObjectivesWeight perceptions have been implicated in weight control related behaviors among children and adolescents, yet studies in mainland China are scarce. We examined the associations of self-perceived weight status and weight misperception with weight control related behaviors in Chinese middle and high school students.MethodsWe used cross-sectional data from the 2017 Zhejiang Youth Risk Behavior Survey which that included 17,359 Chinese students, with 8,616 boys and 8,743 girls. Perceived weight status, as well as height, weight and weight control related behaviors information was collected via a self-reported questionnaire. Odds ratios (ORs) with 95% confidence intervals (CIs) calculated by multinomial logistic regression were used to assess the relationships between weight perceptions and weight control related behaviors.ResultsAmong the 17,359 students aged 9 to 18 years, the mean (SD) age was 15.72 (1.64) years. Overall, 34.19% of children and adolescents perceived themselves as overweight and the prevalence of weight misperception was 45.44%, with 35.54% overestimation and 9.90% underestimation. Children and adolescents perceiving themselves as overweight were more likely to have weight control behaviors, with OR was 2.60 (95% CI: 2.39-2.83) for weight control attempt, 2.48 (2.28-2.70) for exercising, 2.85 (2.60-3.11) for dieting, 2.01 (1.51-2.68) for taking laxatives, 2.09 (1.67-2.02) for taking diet pills, and 2.39 (1.94-2.94) for fasting, respectively, compared to those with right weight status. Among children and adolescents with overestimating weight status, the OR was 2.40 (2.22-2.59), 2.50 (2.31-2.70), 2.85 (2.61-3.11), 1.81 (1.39-2.37), 2.20 (1.77-2.74), and 2.16 (1.77-2.63) for weight control attempt, exercising, dieting, taking laxatives, taking diet pills, and fasting, relative to those with accurate weight perception.ConclusionsSelf-perceived overweight and weight misperception are prevalent in Chinese children and adolescents, and positively associated with weight control related behaviors.
