Body mass index, body shape, and risk of nasopharyngeal carcinoma: A population-based case-control study in Southern China.

ABSTRACT: Whether the association between body size or shape and nasopharyngeal carcinoma (NPC) risk exists or varies by age-specific body size indicators is unclear. In a population-based case-control study conducted in Southern China between 2010 and 2014, self-reported height, weight, and body shape at age 20 and 10 years before interview were collected from 2448 histopathologically confirmed NPC cases and 2534 population-based controls. Body mass index (BMI) was categorized according to the World Health Organization guidelines for Asian populations: underweight (<18.5 kg/m² ), normal weight (18.5-22.9 kg/m² ), overweight (23.0-27.4 kg/m² ), and obese (≥27.5 kg/m² ). Multivariate odds ratios (ORs) with 95% confidence intervals (CIs) were estimated using
