Methodology Overview
This research employs a robust methodology that integrates statistical and computational techniques to analyze complex temporal interactions. It starts with Pearson correlation analysis to establish linear relationships, followed by Augmented Dickey-Fuller (ADF) tests to ensure data stationarity and prevent spurious regressions. The core of the framework is the Granger causality test, which identifies directional causal links and temporal dependencies, enhanced by AIC-based lag optimization for precise modeling. This multi-faceted approach ensures reliable insights into the dynamics of premarital health data.
Key Findings
The study reveals significant insights into the relationship between premarital medical examination rates (RPME) and disease detection rates (RDD). A graded linear correlation was observed, with strong positive correlations during voluntary examination periods. Granger causality tests confirmed lag-dependent causal relationships: RPME fluctuations drive changes in overall RDD at lags 1-4, specific infectious disease detection rates at lag 7, reproductive system disease detection rates at lags 1-4, and internal medicine disease detection rates at lag 1. Conversely, infectious disease and severe genetic disease detection rates also impact RPME at various lags, highlighting bidirectional influences.
Policy Implications
The findings provide critical data-driven decision support for refining premarital examination policies. Understanding the lag-dependent causal mechanisms allows policymakers to design targeted interventions that effectively modulate disease detection outcomes. The identified feedback loops, where disease detection rates influence participation, suggest strategies for enhancing screening efficacy and public engagement. This framework enables dynamic modeling to predict policy outcomes, optimize resource allocation, and strengthen overall public health interventions by fostering a proactive and responsive healthcare system.
0.939
Pearson Correlation (RPME-RDD) in Voluntary Period: A high linear correlation coefficient of 0.939 was found between premarital medical examination rates (RPME) and overall disease detection rates (RDD) during the voluntary examination period (2014-2022), indicating a strong positive association. This highlights the responsiveness of detection rates to participation levels when examinations are elective.

Impact of Policy Shifts on Premarital Health Outcomes
The study observed a dramatic decline in the premarital medical examination rate from 68.02% (2002) to 2.53% (2004) following the elimination of mandatory examination certificates in July 2003. This policy change directly impacted disease detection opportunities, leading to shifts in both overall and specific disease detection rates. Conversely, the introduction of free provision for consultations in 2004 gradually increased participation, demonstrating the responsiveness of public health outcomes to policy adjustments. This highlights the critical role of policy in shaping health behaviors and outcomes.
