ABSTRACT
PURPOSE:
Population studies of the association between zinc intake and mortality yield inconsistent findings. Using data from Jiangsu Nutrition Study, we aimed to assess the association between zinc intake and mortality among Chinese adults.METHODS:
We prospectively studied 2832 adults aged 20 years and older with a mean follow-up of 9.8 years. At baseline, food intake was measured by 3-day weighed food record (WFR) between September and December in 2002. Death occurrence was assessed in 2012 during a household visit as well as by data linkage with the regional death registry. Hazard ratios (HRs) and 95% CI were calculated using competing risks regression (CVD and cancer mortality) and Cox proportional hazards analysis (all-cause mortality).RESULTS:
During 27,742 person-years of follow-up, there were 184 deaths [63 cancer deaths and 70 cardiovascular disease (CVD) deaths]. Dietary zinc to energy ratio was positively associated with cancer and all-cause mortality. Across quartiles of the zinc to energy ratio from low to high, the HR (95% CI) for all-cause mortality was 1.00, 1.80 (95% CI 1.10-2.95), 1.55 (95% CI 0.96-2.50), and 1.85 (95% CI 1.11-3.07), respectively. Comparing the extreme quartiles of the zinc to energy ratio, the HR for cancer mortality was 2.28 (95% CI 1.03-5.04).CONCLUSION:
Zinc intake was positively related to all-cause mortality and cancer mortality.Palabras clave
