The present study aimed to investigate dietary vitamin intake levels and their association with the prevalence of obesity, hypertension, dyslipidemia and hyperglycemia in centenarians in China. From June 2014 to December 2016, a total of 992 centenarians aged >99 years (177 males and 815 females; age range, 100-115 years) were enrolled through household visits in the cities and rural areas of Hainan province. Details regarding food intake were recorded by continuous collection of 7-day food frequency and 24-h dietary review, and dietary vitamin intake levels were calculated according to the Chinese Food Composition Table. The deficiency rates of vitamin A (VA), VE, VB1, VB2, niacin and VC among the centenarians were relatively high and the prevalence of metabolic syndrome (MS) was 53.67% (519/967). The dietary intake levels of VA, VE and PP were significantly higher among the healthy centenarians than among the centenarians with MS (P<0.05). Compared with the lowest quartiles (Q1) of dietary vitamin intake, higher dietary intake levels of VA (Q4) [odds ratio (OR)=0.72; 95% CI: 0.38, 0.99], VE (Q3) (OR=0.61; 95% CI=0.36, 0.88) and VB2 (Q4) (OR=0.51; 95% CI: 0.32, 0.81) were associated with a reduced risk of hypertension (P<0.05). However, higher dietary intake levels of VA, VE, VB2 and PP were associated with increased risks of central obesity, hyperglycemia and low high-density lipoprotein cholesterol levels. A high prevalence of MS and vitamin deficiency were detected among the centenarians and these two items were associated with each other. It was indicated that specific vitamins are necessary for certain centenarians. [ABSTRACT FROM AUTHOR]
