Abstract: Objective: The aim of the present study was to measure the association between non-communicable diseases, body composition and nutrition among the general population of Subang Jaya, Malaysia. Methodology: This cross-sectional study was conducted using self-administered questionnaires with anthropometric measures and collection of blood pressure and glucose levels. Results: Of the 518 respondents, the majority were female (60%), of Malay ethnicity (74.9%) and currently employed (59.7%). Most respondents had up to a secondary school education (45.9%) and exhibited a moderate ability to self-regulate their eating (65.1%). However, there was no association between dietary habits and development of hypertension (p = 0.368), diabetes mellitus (p = 0.5888), heart disease (p = 0.496), or cancer (p = 0.656) in this sample population. Most of our respondents had normal stress levels (69.5%) and there was no association with development of hypertension (p = 0.747), diabetes mellitus (p = 0.300), heart disease (p = 226), or cancer (p = 0.702). Conclusion: Majority of respondents had normal stress levels and moderate self-regulation of eating. While there was an association between body fat percentage, visceral fat and diabetes status, no association was found between eating regulation behavior and both hypertension and diabetes.
