Abstract:

Objective: To systematically review the influencing factors of diabetes mellitus (DM) patients complicated with latent tuberculosis infection (LTBI), and provide a reference basis for subsequent basic and clinical research. Methods: Computerized searches were performed in the Excerpta Medica Database, Medline Biomedical Literature Database, Cochrane Library Database, China Journal Full-text Database, Wanfang Medical Network, and VIP Database, with retrieval periods ranging from the establishment of each database to February 22, 2025. Two trained and qualified researchers independently performed literature searches, quality assessments, and data extraction. Meta-analysis was conducted using R 4.4.3 software. Results: A total of 9 studies were included, involving 3972 cases. The results of Meta-analysis showed that: a household size ≥5 members (OR=1.691, 95%CI: 1.201-2.381), current smoking (OR=1.618, 95%CI: 1.168-2.241), and glycated hemoglobin (HbA1c) >7.0% (OR=1.503, 95%CI: 1.125-2.008) were risk factors for DM patients complicated with LTBI. Conclusion: Household size ≥5 members, current smoking, and glycated hemoglobin >7.0% are risk factors for DM patients complicated with LTBI. Therefore, it is necessary to strengthen health education and awareness for individuals with DM complicated with LTBI, along with accurate identification and targeted interventions for the influencing factors, and to promptly adopt preventive and interventional measures.
