Eligibility Criteria: Residents of 8 communities in urban Shanghai, China, who were aged 40–70 years between 1997 and 2000 for the SWHS and aged 40–74 years between 2002 and 2006 for the SMHS. we excluded participants with a reported total energy intake outside the range of 500–4,000 kcal/day (45 women, 91 men) and those with no follow-up (8 women, 14 men). We further excluded participants who died during the first year of follow-up (145 women, 248 men) to minimize the possibility of reverse causality. One male participant who did not answer all questions about smoking history was also excluded.
