Abstract

 

Aims: The aim of this study was to investigate whether the Western dietary guidelines on fruit and vegetable intake are associated with blood pressure parameters and hypertension among Vietnamese adults.

Methods: Participants included 1384 women and 1049 men aged 18 69 years from the 2015 Vietnam national survey on risk factors of non-communicable diseases. Associations between dietary intake score based on the Dietary Approaches to Stop Hypertension (DASH) guidelines and World Health Organization recommendations on fruit and vegetable consumption and blood pressure parameters and hypertension were evaluated by multivariate regression analyses.

 

Results: Approximately 17.0% and 40.1% of participants met the respective definitions of hypertension according to Joint National Committee 7 (JNC7) and 2017 American College of Cardiology/American Heart Association (ACC/AHA) Hypertension Guideline. Highest tertiles of DASH scores for fruit intake were significantly associated with increased blood pressure parameters, particularly in women. Hypertension was associated with DASH score for fruit intake with odds ratios and 95% confidence intervals for tertiles 2–3 versus tertile 1: 1.31 (0.98, 1.76) and 1.43 (1.05, 1.93) for JNC7; 1.26 (1.01, 1.58) and 1.31 (1.04, 1.66) for 2017 ACC/AHA guideline (all p-trend <0.05). No association with blood pressure parameters and hypertension was observed for DASH score for vegetable intake and meeting World Health Organization recommendations for fruit and vegetable intake.

 

Conclusion: We found an unexpected positive association between DASH score for fruit intake and blood pressure parameters and hypertension among Vietnamese adults. More research is needed in this population to understand the relationship between vegetable and fruit intake with hypertension before a firm conclusion and recommendation are made.
