Summary
ProblemObesity has been associated with increased morbidity and mortality. While obesity in the Navy is less a problem than for the U.S. population as a whole, the physical health and combat readiness of active duty personnel, is a vital concern for the Navy.
PurposeThe purpose of the study was to assess personal, environmental, and psychosocial factors related to obesity in a Navy sample. The goals of the research were: 1) to evaluate demographic characteristics related to obesity, 2) to examine psychosocial mechanisms involved with obesity, and 3) to construct a heuristic model of obesity that includes the environmental, personal and psychosocial components of obesity. Two hypotheses are investigated. Hypothesis 1: obesity will be higher among enlisted personnel and those with less education. Hypothesis 2: obese individuals will exhibit more dysfunctional eating behaviors in response to stress than the nonobese.
ApproachThe sample consisted of 153 subjects. Those whose percent body fat fell within acceptable standards constituted 41% of the sample, while 59% were classified as overfat. Attempts were made to match lean and overfat subjects according to sex, age, ethnicity, and rank.
ResultsThe socioeconomic hypothesis, which stated that lower ranking and less education would be associated with higher percent fat, received support. The psychosocial hypothesis explored eating behaviors and coping in response to stress and was not supported.
ConclusionsThe results suggest that adiposity in the Navy has a strong relationship to obesity-prone food behaviors, family obesity, and lower socioeconomic level.The Navy's weight reduction programs could enhance their behavioral interventions by addressing food obsessions associated with obesity. Treatment for food obsessions should assist the individual toward implementing alternative behaviors to eating, selecting low-calorie foods for in-between meal snacks, and mobilizing social resources as positive reinforcement strategies for long term behavior change. By enhancing the subject's behavioral repertoire, the Navy should benefit from more successful behavioral intervention for weight control.
