The relationship amongst dietary patterns and cardiovascular risk factors in Chinese adults

[摘要] China is facing epidemic of cardiovascular disease propelled by obesity, hypertension, dyslipidaemia, and hyperglycaemia. Epidemiological studies are continuing to show an increase in the prevalence of the aforementioned cardiovascular disease risk factors in the Chinese and studies are yet to shown signs of abating. Diet is able to affect the cardiovascular function by influencing the risk factors but very little is known about the diets of the Chinese. This thesis identified three dietary patterns (Non-nut and Non-cruciferous Vegetable, High Protein-High Fat, Omnivorous) using principal component factor analysis and examined the cross-sectional relationships with hyperglycaemia, hypertension, and metabolic syndrome in 20,146 middle-aged and older Chinese adults. The Non-nut and Non-cruciferous Vegetable diet was adversely associated with hyperglycaemia and the metabolic syndrome but showed no association with hypertension. The High Protein-High Fat diet was associated with reduced risk of hyperglycaemia and hypertension but exhibited no relationship with the metabolic syndrome. The Omnivorous diet was inversely associated with hyperglycaemia and the metabolic syndrome but demonstrated an adverse association with hypertension. In addition, the thesis developed a conceptual model and highlighted the putative mechanisms mediating the relationships between the High Protein-High Fat diet and cardiovascular disease risk factors using the structural equation model.
