The fragmentation of epidemiological studies can have several negative consequences:
1. Inconsistent Findings: Isolated studies may produce conflicting results, complicating the interpretation and application of findings. 2. Limited Generalizability: Research that focuses on specific populations or conditions may not be applicable to other groups, reducing the overall impact. 3. Duplication of Effort: Fragmented studies can lead to redundant research, wasting valuable resources and time. 4. Policy Gaps: Incomplete data and understanding can hinder the development of effective public health policies and interventions.
