Association between dietary antioxidant vitamins intake and homocysteine levels in middle-aged and older adults with hypertension: a cross-sectional study.

ABSTRACT:

Objectives

Plasma total homocysteine (tHcy) has been implicated in the development of cardiovascular disease. This study aimed to assess the relationship of dietary antioxidant vitamins intake with tHcy levels in middle-aged and older adults with hypertension.

Design

A cross-sectional study.

Setting

The survey was conducted in the Nanshan district of Shenzhen.

Participants

A total of 1465 middle-aged and older adults with hypertension were included between July and September of 2013.

Measurements

Hyperhomocysteinaemia (HHcy) was defined as tHcy ≥15 µmol/L. Some dietary antioxidant vitamins (vitamin C (VC) and vitamin E (VE), carotenes, retinol, lutein) intake was estimated using the Food Frequency Questionnaire. Sociodemographic and potential covariates
