Association of consumption of sugar-sweetened beverages with elevated blood pressure among college students in Yunnan Province, China

Although some studies have examined the association between eating behaviour and elevated blood pressure (EBP) in adolescents, current data on the association between sugar-sweetened beverages (SSB) and EBP in adolescents in Yunnan Province, China, are lacking. Cluster sampling was used to survey freshmen at a college in Kunming, Yunnan Province, from November to December. Data on SSB consumption were collected using an FFQ measuring height, weight and blood pressure. A logistic regression model was used to analyse the association between SSB consumption and EBP, encompassing prehypertension and hypertension with sex-specific analyses. The analysis included 4781 college students. Elevated systolic blood pressure (SBP) and diastolic blood pressure (DBP) were detected in 35·10 % (1678/4781) and 39·34 % (1881/4781) of patients, respectively. After adjusting for confounding variables, tea beverage consumption was associated with elevated SBP (OR = 1·24, 95 % CI: 1·03, 1·49, = 0·024), and carbonated beverage (OR = 1·23, 95 % CI: 1·04, 1·45, = 0·019) and milk beverage (OR = 0·81, 95 % CI: 0·69, 0·95, = 0·010) consumption was associated with elevated DBP in college students. Moreover, fruit beverage (OR = 1·32, 95 % CI: 1·00, 1·75, = 0·048) and milk beverage consumption (OR = 0·69, 95 % CI: 0·52, 0·93, = 0·014) was associated with elevated DBP in males. Our findings indicated that fruit and milk beverage consumption was associated with elevated DBP in males, and no association was observed with EBP in females.
