Core Viewpoint - The increasing prevalence of diabetes among younger populations, including middle-aged individuals and even adolescents, is a significant concern, highlighting the need for awareness and preventive measures in the workplace [1][2]. Group 1: Rising Diabetes Cases - More middle-aged and even young individuals are being affected by diabetes, challenging the traditional view that it is primarily an elderly disease [1]. - The changing lifestyle, characterized by irregular habits, high-stress work environments, and unhealthy eating patterns, is contributing to the younger onset of type 2 diabetes [1]. Group 2: Importance of Prevention - Health interventions focusing on lifestyle changes are essential for the prevention and treatment of diabetes, emphasizing the need for early lifestyle modifications [1][2]. - The three levels of diabetes prevention include: - Primary prevention: Timely lifestyle interventions for high-risk individuals, focusing on diet and physical activity [1][2]. - Secondary prevention: Early screening and diagnosis for high-risk groups, followed by standardized management to control blood sugar levels [1][2]. - Tertiary prevention: Management of long-term diabetes patients to slow the progression of complications and improve quality of life [2].
