Chi-square analysis of people’s knowledge of balanced diet and aerobic exercise at different stages of type 2 diabetes mellitus

Patients with Type 2 Diabetes Mellitus (T2DM) die every eight seconds in the world. T2DM is still not eradicated at home and abroad at present, thus just control. A balanced diet and aerobic exercise (intervention treatment) can reduce risk factors and the incidence of diabetes and diabetic complications, which prevents or delays the onset and progression. The survey of people's knowledge of balanced diet and aerobic exercise has been conducted in Luzhou, Neijiang, Nanchong and Ziyang of Sichuan province and Tongren of Guizhou province from June to September 2019. A total of 865 subjects' questionnaires have been collected. Taking prediabetes as baseline, people's knowledge difference of balanced diet and aerobic exercise is compared forwards in low- or high-risk stage and backwards in the diabetes stage and diabetic complication stage through Pearson χ2 test and the correlation coefficient Cramer's V and Φ. The knowledge difference in prediabetes and high-risk (χ2=4.2996, p=0.0224, Cramer's Φ=0.1038) is statistically significant, and the difference in prediabetes and diabetic complications (χ2=231.5272, p< 0.0000001, Cramer's Φ=0.5905) is also statistically significant. Knowledge of balanced diet and aerobic exercise at prediabetes stage is significantly higher than that in high-risk and that in diabetic complications. Doctors, nurses and researchers should use the Internet and door-to-door to educate people about the importance of balanced diet and aerobic exercise during prediabetes and diabetic complications in T2DM.
