Body mass index and the risk of head and neck cancer in the Chinese population.

Objective: To investigate potential associations between body mass index (BMI) and head and neck cancer (HNC) risk in an East Asian population.

Methods: We conducted a hospital-based multicenter case-control study in East Asia including 921 cases and 806 controls. We estimated the odds ratios (ORs) and 95% confidence intervals (95% CI) for HNC risks by using logistic regression, adjusting on potential confounders.

Diet and the risk of head-and-neck cancer among never-smokers and smokers in a Chinese population.

Background: Few studies have been conducted in China to investigate the association between diet and the risk of head-and-neck cancer (HNC). The aim of this study was to determine the relationship between diet and HNC risk in the Chinese population and to examine whether smoking status has any effect on the risk.

Methods: Our multicenter case-control study included 921 HNC cases and 806 controls.

Family History of Cancer and Head and Neck Cancer Risk in a Chinese Population.

Background: The aim of this study was to investigate whether family history of cancer is associated with head and neck cancer risk in a Chinese population.

Materials And Methods: This case-control study included 921 cases and 806 controls. Recruitment was from December 2010 to January 2015 in eight centers in East Asia.

Oral lesions, chronic diseases and the risk of head and neck cancer.

Objectives: The aim of our study is to explore the role of the history of oral lesions and chronic diseases on the risk of head and neck cancer in a Chinese population.

Materials And Methods: Our case-control study included 921 head and neck cancer cases and 806 controls. We obtained medical history information by administering questionnaires to both cases and controls.
