The proposed bill, S.B. No. 1645, mandates a comprehensive study by the Texas Tech University Health Sciences Center focusing on health, nutrition, physical activity, and chronic health issues in Texas. The study will analyze historical dietary habits, physical activity levels, and the prevalence of chronic diseases over the past 50 years. It will also evaluate the economic impact of chronic health issues, including healthcare spending trends and the costs associated with private insurance. The bill emphasizes the use of Texas-specific data, with national data as a secondary option when state-level data is unavailable.

Additionally, the bill outlines the collaboration required from various state agencies, such as the Department of State Health Services and the Health and Human Services Commission, to assist in the study. A report detailing the findings must be submitted by September 1, 2026, to the Health and Human Services Commission and relevant legislative committees. The act is set to take effect on September 1, 2025, and will expire on January 1, 2027.
