Multiphasic Health Checkup Evaluation: a 16-year follow-up

Area of Science:

• Preventative Medicine
• Clinical Trials
• Public Health

Background:

• Long-term clinical trials are crucial for evaluating the impact of screening programs.
• Multiphasic health checkups (MHCs) aim to detect diseases early for better outcomes.
• Understanding the long-term effects of regular health screenings is vital for public health policy.

Purpose of the Study:

• To evaluate the effectiveness of urging annual multiphasic health checkups (MHCs) over 16 years.
• To assess the impact of a proactive screening program on mortality from specific causes.
• To determine if regular MHCs influence overall mortality or self-reported disability.

Main Methods:

• A long-term clinical trial involving 5156 individuals (study group) urged for annual MHCs.
• A control group of 5557 comparable individuals not urged for MHCs, followed comparably.
• Comparison of mortality rates from 'potentially postponable' causes, other causes, and total mortality between groups over 16 years.

Main Results:

• The study group showed a 30% reduction in deaths from 'potentially postponable' causes (p<0.05), notably colorectal cancer and hypertension.
• This mortality reduction was most significant in the early years of the study.
• No statistically significant differences were observed in mortality from other causes, total mortality, or self-reported disability between the groups.

Conclusions:

• Urging middle-aged individuals to undergo regular MHCs within a prepaid healthcare plan led to a substantial decrease in deaths from specific diseases.
• Proactive screening programs can effectively reduce mortality from targeted, preventable conditions.
• The findings support the implementation of encouraged regular health checkups for specific populations.
