Abstract
Purpose: Cancer-related genes and pathways have recently been implicated in a genome-wide meta-analysis of head size. In the current study, we aimed to evaluate the association between adult head circumference and the risk of cancer.
Methods: This is a cohort study using data from the Hong Kong Osteoporosis Study, where 1,301 participants aged 27-96 years with head circumference measured between 2015 and 2019, and without a history of cancer, were followed up to 15 January 2024. Incident cancers were identified using electronic medical records from a territory-wide database. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using Cox proportional hazards regression, adjusting for age, sex, height, weight, education, smoking, alcohol drinking, physical activity, and family history of cancer, as well as accounting for familial clustering.
Results: The median head circumference was 53 cm (interquartile range [IQR]: 51-54) and 54 cm (IQR: 53-55) for women and men, respectively. During a median follow-up of 6.9 years, 66 individuals were diagnosed with cancer. In the adjusted model, a larger head circumference was associated with an increased risk of any cancer (HR per cm increase: 1.17; 95% CI 1.00-1.36). Results remained similar when adjusting for waist-to-hip ratio instead of weight or when additionally adjusting for serum calcium and phosphorus levels. When stratified by cancer sites, head circumference was most strongly associated with colorectal cancer (HR per cm increase: 1.81; 95% CI 1.14-2.90) and prostate cancer (HR per cm increase: 1.58; 95% CI 1.16-2.16).
Conclusion: Head circumference is positively associated with the risk of cancer independently of height, weight, and other cancer risk factors.
期刊介绍：
Cancer Causes & Control is an international refereed journal that both reports and stimulates new avenues of investigation into the causes, control, and subsequent prevention of cancer. By drawing together related information published currently in a diverse range of biological and medical journals, it has a multidisciplinary and multinational approach.
The scope of the journal includes: variation in cancer distribution within and between populations; factors associated with cancer risk; preventive and therapeutic interventions on a population scale; economic, demographic, and health-policy implications of cancer; and related methodological issues.
The emphasis is on speed of publication. The journal will normally publish within 30 to 60 days of acceptance of manuscripts.
Cancer Causes & Control publishes Original Articles, Reviews, Commentaries, Opinions, Short Communications and Letters to the Editor which will have direct relevance to researchers and practitioners working in epidemiology, medical statistics, cancer biology, health education, medical economics and related fields. The journal also contains significant information for government agencies concerned with cancer research, control and policy.
