SMU study finds friends directly influence cancer screening

Friendship networks in later life are directly associated with regular participation in breast, cervical, and colorectal cancer screenings, whereas family influence operates primarily through shaping knowledge and attitudes toward screening, according to a study by Singapore Management University’s Center for Research on Successful Ageing.

Key Clinical Takeaways:
• Friendship networks show a direct association with regular breast, cervical, and colorectal cancer screenings among adults aged 50 to 79.
• Family influence primarily shapes awareness, health knowledge, and attitudes regarding cancer screening rather than directly associating with screening behavior.
• Enrolment in the Healthier SG program correlates with increased screening regularity, a pathway supported by peer and friendship networks.

Analysis of 7,139 Participants in the Singapore Life Panel

The study, titled Who encourages screening? Examining family, friendship and other drivers of health screening participation in later life, analyzed data from 7,139 participants aged 50 to 79. News-Medical reported that the analysis evaluated whether respondents adhered to recommended screening intervals for cervical, colorectal, and breast cancer. Researchers observed that friendship ties were directly tied to regular screenings across most analyzed demographic groups. The study excluded individuals with a prior cancer diagnosis and utilized structural equation modeling to assess associations between social influence, health knowledge, and preventive care programs.

Differences Across Age Groups and Screening Types

The impact of social connections varies depending on age and the specific type of cancer screening. Enrolment in the Healthier SG initiative was associated with more regular examinations, with friends potentially encouraging program participation. This pattern held true for all evaluations except colorectal screening among adults aged 50 to 59. Direct associations between friendship contacts and routine colorectal checks were absent among participants aged 60 to 69 and 70 to 79. For individuals in their sixties, researchers identified multiple pathways influencing screening regularity, encompassing family dynamics, peer networks, and Healthier SG enrolment.

Non-Kin Peer Support Bridges Gaps in Health Participation

Education levels and housing types also influenced screening regularity, though their specific effects varied by age and cancer category. Because socioeconomic factors remain difficult to modify, the study suggests that non-kin peer support may bridge gaps in preventive health participation. Professor Paulin Straughan, Director of ROSA, noted that older adults have diverse needs, and understanding these differences allows public health strategies to move beyond uniform approaches. The findings indicate that population-level interventions should actively foster supportive non-kin relationships, particularly for individuals with fewer family or socioeconomic resources.
