Prevalence of tachyphagia at lunch and associated factors in a population of workers
Résumé
Purpose: Obesity is a public health problem worldwide. The eating habits of French workers need to be clarified. In particular, tachyphagia (meal lasting < 15 min) promotes weight gain. The present study aimed to investigate the presence of tachyphagia at lunchtime, the factors associated with tachyphagia, and the relationship between tachyphagia and obesity among workers.
Methods: This cross-sectional study was conducted between January and May 2016 in five departments of occupational medicine. An anonymous self-administered questionnaire was used to gather general declarative data, such as weight and height (to calculate body mass index [BMI]) and information about lunchtime habits, including the time spent eating.
Results: A total of 415 workers with a mean age of 41.1 ± 12.6 years were included. The mean BMI was 23.8 ± 4.6 kg/m2, and the prevalence of obesity was 15.9%. Tachyphagia occurred in 20.3% of the cases and was more frequent in younger workers. Multivariate analysis revealed that skipping meals, eating standing up, and eating fast food were positively associated with tachyphagia (p = 0.015, p = 0.028, and p = 0.027, respectively). Older age and eating with colleagues/friends were negatively associated with tachyphagia (p = 0.003 and p < 0.0001, respectively). No significant association was observed between tachyphagia and obesity.
Conclusion: Our study provides important information about the lunchtime habits of workers. Maintaining commensality is crucial, particularly in young workers. Companies should play a role in organising their employees' lunch breaks. Level III Evidence obtained from well-designed cohort or case-control analytic studies.
