Impact of military culture and experiences on eating and weight-related behavior
Abstract: Disordered eating behaviors and obesity are becoming increasingly common among United States military personnel. However, little research has explored the role of the military environment as it may influence the development of disordered eating among personnel. The present qualitative analysis examined beliefs about how military experiences affected eating and weight-related behaviors. Military personnel who served within the last year and a year or more ago (n = 250) were recruited using Amazon's Mechanical Turk (mTurk). Data included in the present study consisted of participant responses to three open-ended questions, analyzed by means of content and thematic analysis. Analyses yielded eight themes: eating extremely quickly, strict mealtime regimens, the pressure to “make weight,” food insecurity, difficulty after military, food quality/content, overeating behavior, and military superior maltreatment. The current study provides a preliminary examination of the role of the military culture and experiences in the development of unhealthy eating and weight-related behaviors and offers suggestions for future research and interventions.
Abstract: Disordered eating is a prevalent and relevant health concern that remains understudied among U.S. military veterans. Avoidant/restrictive food intake disorder (ARFID) is a newly recognized feeding and eating disorder characterized by overly restrictive eating due to (a) picky eating, (b) lack of appetite, and (c) fear of aversive consequences related to eating. The Nine-Item ARFID Screen (NIAS) is a recently developed ARFID screening tool with initial validation studies demonstrating psychometric support. However, the psychometric properties of the NIAS have not been investigated in a veteran sample. To advance our understanding of ARFID screening tools that may be appropriate for use in veterans, the present study examined the factor structure of the NIAS using survey data from a large national sample of recently separated veterans (N = 1,486). Measurement invariance across key subgroups was tested in addition to exploring differential associations between the NIAS and related constructs. Results suggested that a three-factor model provided an excellent fit of the data and demonstrated scalar invariance across self-identified men and women, race and ethnicity, and sexual and gender minority (SGM) identity. Some subgroups had higher latent means on the picky eating (women, SGM, non-Hispanic Black), appetite (women, SGM), and fear (women) factors. The NIAS had some overlap with another measure of disordered eating and was moderately correlated with psychosocial impairment and mental health. Overall, the NIAS may be a useful screening tool for ARFID in veterans, given support for the three proposed subscales and equivalence across diverse identities.
