Brief summary

This is an observational study tracking families and offspring of three cohorts from the 1986 Da Qing study: newly diagnosed diabetes, impaired glucose tolerance, and normoglycemia groups. Based on the original participants, the study will further include their spouses, first to third-generation offspring, and spouses of the offspring. General demographic information will be collected, and anthropometric measurements will be refined. A structured questionnaire will be used to gather disease history, family history of diabetes, and related information. Comprehensive diabetes-related laboratory screening and complication assessments will be conducted. A standardized biobank will be established, including blood and urine samples from the Da Qing Offspring Study, to support future research on epigenetics, metabolomics, and other mechanisms.

Interventions

Dietary intervention: 30kcal energy intake per kilogram of body weight per day, increase vegetable intake, control sugar and alcohol intake, encourage overweight and obese people to lose weight, lose 0.5-1kg per month until the weight reaches the target. Exercise intervention: Appropriate physical activity in spare time, 30-40 minutes per day, 5 times a week.

MeasureTime frameDescription
Cumulative incidence rate of diabetesThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the cumulative incidence rate of diabetes at the end of the study through interview, medical record review, physical examination

Secondary

MeasureTime frameDescription
weightThrough study completion, an average of about 1.5 yearsThe subject's weight is recorded and the results are reported in kilograms.
waist circumferenceThrough study completion, an average of about 1.5 yearsThe subjects' waist circumference was recorded and the waist circumference results were reported in centimeters.
HeightThrough study completion, an average of about 1.5 yearsThe subject's height was recorded, and the results were recorded in centimeters.
Exercise frequency and intensityThrough study completion, an average of about 1.5 yearsThe subjects' daily exercise frequency and intensity were recorded.
Coronary heart disease incidenceThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of coronary heart disease at the end of the study through interview, medical record review, physical examination
all-cause deathsThrough study completion, an average of about 1.5 yearsThis study counted all-cause deaths at the end of the study through death certificate, medical record review, family interview
incidence of diabetic peripheral neuropathyThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of diabetic peripheral neuropathy at the end of the study through interview, medical record review, physical examination
other cause mortalityThrough study completion, an average of about 1.5 yearsThis study statistically analyzed other cause mortality at the end of the study through death record, medical record review, family interview
incidence of blindnessThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of blindness at the end of the study through interview, medical record review, physical examination
Diabetic retinopathy incidenceThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of diabetic retinopathy at the end of the study through interview, medical record review, physical examination
Diabetic nephropathy incidenceThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of diabetic nephropathy at the end of the study through interview, medical record review, physical examination
Peripheral vascular disease incidenceThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of peripheral vascular disease at the end of the study through interview, medical record review, physical examination
cardiovascular mortality rateThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the cardiovascular mortality rate at the end of the study through death certificate, medical record review, family interview
Stroke incidenceThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of stroke at the end of the study through interview, medical record review, physical examination
dietary habitsThrough study completion, an average of about 1.5 yearsThe subjects' eating habits and dietary preferences were assessed through patient interviews.
health-related quality of lifeThrough study completion, an average of about 1.5 yearsThe EuroQol questionnaire or health status questionnaire was administered through patient interviews to assess the subjects' health-related quality of life.
blood pressureThrough study completion, an average of about 1.5 yearsDuring the visit, the subjects' systolic and diastolic blood pressures were measured at rest by physical examination. The measurements were performed twice and the average was taken.
blood sugarThrough study completion, an average of about 1.5 yearsBlood samples were collected from the subjects at 1 hour and 2 hours after the steamed bread meal when they were fasting. The blood samples were used to test blood sugar levels and blood lipids, including total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol.
blood lipidThrough study completion, an average of about 1.5 yearsVenous blood was collected from the subjects in a fasting state. The blood samples were used to test blood lipid status, including total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol.
skin AGEThrough study completion, an average of about 1.5 yearsThe skin AGE of the subjects was measured by physical examination. After cleaning the inner skin of the forearm, the AGE Reader probe was gently placed on the skin surface, the excitation light was emitted and the fluorescence intensity was recorded. The results were repeated 3 times and the average value was taken.
Tidal VolumeThrough study completion, an average of about 1.5 yearsThe subjects were assessed for Tidal Volume, which reflects the ventilation efficiency in the basic breathing state. Tidal Volume is measured in liters.
Functional Residual CapacityThrough study completion, an average of about 1.5 yearsSubjects were assessed for Functional Residual Capacity, which reflects lung capacity. Functional Residual Capacity is measured in liters.
Forced Vital CapacityThrough study completion, an average of about 1.5 yearsThe subjects were assessed for Forced Vital Capacity, which reflects the overall ventilation capacity of the lungs. Forced Vital Capacity is measured in liters.
Forced Expiratory Volume in 1 secondThrough study completion, an average of about 1.5 yearsThe subjects were assessed for Forced Expiratory Volume in 1 second, which reflects respiratory reserve capacity. Forced Expiratory Volume in 1 second is measured in liters.
Heart failure incidenceThrough study completion, an average of about 1.5 yearsThis study statistically analyzed the incidence of heart failure at the end of the study through interview, medical record review, physical examination
