Abstract
Adolescents’ unhealthy eating leads to them to adopt certain measures such as
a diet, fasting and other behaviours that are likely to reduce body weight. The measures
in turns lead to eating disorders and series of complications, such as impaired digestive
system function, endocrine disorders, amenorrhea, hypoglycaemia, malnutrition, or
physiological damage to various organ systems, and even life-threatening. It will affect
the physical and mental health of the young and incurs high medical costs in one's
country. In the long term it will be a physical and mental health issue that will increase
medical expenses to treat it. Therefore, using the Theory of Planned Behaviour, this
study was conducted to identify the factors that influence eating disorders among
university students in the province of Gansu, China. Data was analysed using IBM
SPSS and PROCESS 4.0 to answer all research questions developed. Results showed
that there was significant difference in attitude towards physical activity, subjective
norm, perceived behavioural control, body shape, self-esteem, and intention to engage
in physical activities. between gender and body mass index (BMI). Gender and BMI
also moderate the relationship between intention, body shape, self-esteem, and eating
disorder. However, different gender and BMI in different attitudes (AT), subjective
norms (SN), perceived behavioural control (PBC), body shape (BS), self-esteem (SE),
and intention (IN) scores have significance. Family incomes only have a significant in
self-esteem (SE).
