Abstract

Purpose: This study investigated the relationship between 3 major constructs of the theory of planned behavior (TPB), i.e., attitude, subjective norms and perceived behavioral control (PBC) and past experience of healthy eating and intentions of healthy eating in the short-term and long-term in adults living in Shanghai and parts of Anhui Province, China. Methods: The online study questionnaire for this cross-sectional study was based on previously validated items. A total of 408 Chinese adults (aged 18-64 years) residing in Shanghai and parts of Anhui Province, China were included to examine relationships between 3 major constructs of TPB and past experience of healthy eating, and short-term and long-term intentions of healthy eating. Multiple linear regression model adjusted for age and body mass index (BMI) was employed to test relationships. Results: Only PBC among 3 major constructs of TPB was significantly related to short-term (p < 0.001) and long-term (p = 0.002) intention of healthy eating after adjustment for age and BMI. Past experience of healthy eating was more significantly related to long-term intention (p < 0.001) compared to short-term (p = 0.020) intention of healthy eating. The short-term and long-term intention models explained 70.5% and 48.8% of the variance, respectively. Conclusion: PBC is a potential determinant of both short-term and long-term behavioral intention of healthy eating regardless of past experience of healthy eating in adults residing in Shanghai and parts of Anhui Province, China. Our results indicate that programs promoting healthy eating to Chinese adults incorporate PCB to perform healthy eating under his or her control.

본 연구 결과, 상하이와 안후이성 지역에 거주하는 중국 성인에서 인지된 행동통제력은 과거 건강한 식행동 경험과 관계없이 건강한 식행동의 장단기 행동 의도에 대한 잠재적 결정요인으로 관찰되었다. 이러한 결과는 급변하는 경제 발전 중에서 만성질환 예방을 위해 건강한 식행동의 중요성을 강조하고 있는 중국에서 성인들의 건강한 식행동을 도울 수 있는 근거자료로 활용될 수 있을 것이다. 향후 중국 내 다양한 인구집단에서의 추가 연구나 대규모 조사연구 및 건강한 식행동을 위한 개인의 인지된 행동통제력을 강화하는 영양 중재나 영양교육 등에 본 연구결과가 의미있는 기초자료가 되기를 기대한다.
