BMI as a risk factor for the development of chronic rhinosinusitis: a prospective population-based study.

PURPOSE: Obesity is a growing, global health problem and previous cross-sectional studies have demonstrated an association between obesity and chronic rhinosinusitis (CRS). There is, however, a lack of prospective studies regarding the impact of obesity on developing (new-onset) CRS. METHODS: Questionnaire-based data (n = 5769) relating to new-onset CRS and Body Mass Index (BMI) were collected in 2013 and 2018 from the Telemark population study in Telemark, Norway. Odds ratios for the risk of new-onset CRS in 2018 in relation to BMI in 2013 were calculated, adjusted for smoking habits, asthma, gender and age. RESULTS: When comparing the group with normal weight (18.5 ≤ BMI < 25) with the obese group (BMI ≥ 30), the odds of new-onset CRS was 53% higher [OR 1.53 (1.11, 2.10)] in the obese group. CONCLUSION: CRS is a multifactorial disease with different phenotypes and it is important to consider obesity when assessing patients with CRS in a clinical setting.

Chronic Rhinosinusitis Related to Occupational Exposure: The Telemark Population Study.

OBJECTIVE: The aim of this study was to investigate the association between occupational exposure and chronic rhinosinusitis. METHODS: A random population from the region of Telemark, aged 16 to 50 years, answered a respiratory questionnaire including questions on chronic rhinosinusitis and exposure in the occupational environment. RESULTS: A total of 16,099/48,142 subjects responded. The prevalence of chronic rhinosinusitis was 9%. Exposure associated with chronic rhinosinusitis comprised paper dust [odds ratio (OR) 1.3, 95% confidence interval (95% CI) 1.1 to 1.5], cleaning agents (OR 1.2, 95% CI 1.0 to 1.3), metal dust (OR 1.3, 95% CI 1.1 to 1.6), animals (OR 1.2, 95% CI 1.0 to 1.5), moisture/mould/mildew (OR 1.3, 95% CI 1.1 to 1.5), and physically strenuous work (OR 1.4, 95% CI 1.2 to 1.7). CONCLUSION: Occupational exposure to paper dust, cleaning agents, metal dust, animals, moisture/mould/mildew, and physically strenuous work was independently related to having chronic rhinosinusitis. An occupational history should be reviewed when assessing patients with chronic rhinosinusitis.
