Data collection encompassed demographic characteristics, lifestyle behaviors, laboratory test result, and physical examination findings, obtained at both baseline and during follow-up periods through structured epidemiological surveys and clinical assessments. Various obesity indices were calculated, including body mass index(BMI), waist-to-height ratio(WHtR), a body shape index(ABSI) and body roundness index(BRI). We also computed the coefficients of variation for these obesity indices during the follow-up period. A Cox proportional hazards regression model was used to analyze the association between obesity indices at baseline and follow-up, and the risk of developing microvascular complications. Additionally, receiver operating characteristic(ROC) curves were used to analyze the predictive efficacy of the coefficients of variation for BMI, WHtR, ABSI and BRI in relation to microvascular complications, and the areas under the curve(AUCs) were calculated.</p><p><strong>Results: </strong>A total of 27 635 patients with type 2 diabetes(T2DM) were included, contributing to 153 717 person-years of follow-up. During this period, 12 969 new cases of microvascular complications were identified, resultsing in an incidence rate of 84.37 cases per 1000 person-years. Patients were categorized into two groups based on the occurrence of complications: those with microvascular complications and those without. There was no significant difference in blood glucose levels between the two groups at baseline. After adjusting for sociodemographic characteristics, laboratory indicators, and potential confounders such as a history of hypertension and hyperlipidemia, it was found that only the WHtR(HR=1.027, 95%CI 1.008-1.046), ABSI(HR=1.035, 95%CI 1.018-1.053) and BRI(HR=1.030, 95%CI 1.011-1.049) were independently associated with the risk of microvascular complications at baseline, while waist circumference(HR=1.010, 95%CI 0.992-1.029) and BMI(HR=0.985, 95%CI 0.967-1.002) were not significantly related(P>0.05). During the follow-up period, the coefficients of variation for all obesity indices were independently associated with an increased risk of microvascular complications. Among them, abdominal obesity indices, such as waist circumference(HR=0.063, 95%CI 1.057-1.069), WHtR(HR=1.060, 95%CI 1.054-1.066), and ABSI(HR=1.062, 95%CI 1.058-1.066), were most strongly linked to the risk of microvascular complications.

The differences in parental control and peer relationship scores among middle school students of different genders were statistically significant(P&lt;0.01). The differences in parental control, pro-social behavior and peer relationship scores among students from different cities, urban-rural areas and rural areas were statistically significant(P&lt;0.01). Parental control was positively correlated with both pro-social behavior scores of junior high school students(r=0.315). Peer relationship played a masking effect between parental control and junior high school students&apos; pro-social behavior(a×b and c' heteroscedastic, |a×b|/c'=8.50%).
