Cultural and Western Influences on the Nutrition Transition in Thailand

Abstract

The impact of economic development and urbanisation on nutrition and dietary changes in transitional countries has been well researched. It generally has been found that there is a positive correlation between economic development, urbanization, and negative nutrition transitions with the result of growing levels of obesity and diet related non-communicable diseases. However, the impact of Western influences and culture on specific eating styles associated with the nutrition transition has been less studied. There is limited information about cultural and Western influences on eating styles in Thailand. Recent findings suggest that Thailand may have progressed further along the nutrition transition model, in terms of unhealthy eating styles, than would be expected based on economic development. This study was designed to determine the prevalence of current eating styles and eating motivations among Thai university students. University students were chosen for evaluation as they are thought to represent the forefront of dietary trends and nutrition changes in a population. Convenience samples from four different universities in south-central and northern Thailand were selected. The following scales were used to assess eating and dieting styles and attitudes among 662 Thai undergraduate and graduate students: Motivation For Eating Scale (MFES), Eating Attitudes Test-26 (EAT-26), and Cognitive Dieting Behavior Scale (CBDS). All scales have been shown to be reliable and valid in previous research. For this study, scales were translated into Thai, reverse translated, and pilot tested to ensure cultural relevancy and the conveyance of intended meanings. Basic demographic information was also obtained, including age, gender, year in school, marital status, height and weight, and income. Results indicated that Thai students exhibit significant levels of dieting behaviour and extrinsic eating based on CBDS and MFES scores (with the exception of environmental eating). For most negative eating styles, females scored higher than males. It was also found that high levels of dieting and extrinsic eating were positively correlated with body mass index, suggesting the possible risk of future weight gain and obesity. While the occurrence of eating disordered attitudes based on EAT-26 scores was low (13%), analysis of EAT-26 scores indicated that the occurrence of eating disordered attitudes was strongly correlated with dieting behaviour among this population. The results support the need for a programme to educate Thai students, especially females, regarding healthy patterns of dieting and eating attitudes in order to prevent future weight gains and eating disorders predicted by the nutrition transition model.
