Background: Cancer is the leading cause of death among Chinese Americans (CAs). Although death rates of cancers can be significantly reduced by screening cancers at an early stage, cancer screening (CS) rates are low among CAs. Interventions on CS may increase the uptake rates of CS and help to decrease the death rates of cancers in CAs. Objectives: This study aims to summarize the intervention methods on CS among CAs and compare effects of various intervention methods on the outcomes of CS, including knowledge levels of CS, intentions to complete CS, and actual completions of CS. Methods: A systematic review and meta-analysis design was used. Keyword searching was conducted on PubMed, Google Scholar, PsycINFO, and CINAHL. Inclusion and exclusion criteria were applied. The PEDro scale was used to evaluate the quality of the studies. Data was analyzed using Review Manager Version 5.4 software. Random effect model and subgroup analyses were conducted. Results: The search yielded 13 eligible studies. All of the reviewed interventions were culturally tailored. Systematic review results were categorized by intervention delivery objects, intervention led, intervention contact, intervention types, and intervention focus according to group consensus. Meta-analysis results showed that the interventions on CS had a positive effect on all outcomes, including a 1.58 (95% CI, 1.17-2.14; P = 0.003), 1.78 (95% CI, 1.27-2.48; P = 0.0007), and 1.72 (95% CI, 1.22-2.42; P = 0.002) effect on knowledge of CS, intentions to complete CS, and completions of CS, respectively, compared to the control group. The subgroup analysis suggested that physician-led, individual-based, face-to-face client- focused interventions with multiple components increased CS among CAs, with the OR ranging from 1.60 (95% CI, 1.08-2.39; P = 0.02) to 3.11 (95%CI, 1.02-9.49; P = 0.05). Discussion: Interventions on CS significantly increased CAs' knowledge of CS, intentions to complete CS, and completions of CS. Physician-led, individual-based, face-to-face client-focused interventions with multiple components should be utilized for CAs.
