The average age of participants was 56.21 years for men, and 54.75 years for women. More than 60% of participants in all three survey sites reported an average consumption of fruit and vegetable three or more times per week. In Hotan and Ili, the staple food was wheaten food, whereas, in Urumqi, rice and wheaten food was the food staples. Consumption of white meat, such as fish and poultry, was lower in the three survey locations. Based on self-reported disease from study participants, the five most common chronic diseases among participants across all three survey locations were dyslipidaemia, hypertension, cholecystitis, diabetes, ischaemic heart disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Future plans<\/jats:title>\n                    <jats:p>First, we will collect all health-related records of the study participants in January each year for the previous year.
