Influenza and Other Respiratory Viruses DOI: 10.1111/irv.12019. Background Findings from studies examining the association between obesity and acute respiratory infection are inconsistent. Few studies have assessed the relationship between obesity-related behavioral factors, such as diet and exercise, and risk of acute respiratory infection. Objective To determine whether community prevalence of obesity, low fruit/vegetable consumption, and physical inactivity are associated with influenza-related hospitalization rates. Methods Using data from 274 US counties, from 2002 to 2008, we regressed county influenza-related hospitalization rates on county prevalence of obesity (BMI ≥ 30), low fruit/vegetable consumption (<5 000="" 100="" 11="" 12="" 1="" 5="" 6="" 7="" 8="" 95="" a="" accounting="" active="" adjusted="" adjusting="" after="" all="" an="" and="" as="" associated="" care="" ci="" communities="" community-level="" conclusions="" confidence="" confounders="" consumption="" coverage="" day="" even="" exercise="" for="" fruit="" greater="" have="" high="" higher="" hospitalization="" in="" inactivity="" included="" increase="" increases="" influenza-related="" insurance="" interval="" less="" likely="" low="" lower="" minutes="" model="" month="" more="" number="" obesity.="" obesity="" of="" p="" per="" physical="" physically="" physicians="" population.="" populations="" prevalence="" primary="" rate="" rates.="" rates="" ratio="" recreational="" respectively.="" results="" same="" servings="" similarly="" such="" tended="" the="" three="" to="" variables="" vegetable="" was="" were="" when="" while="" with="">© 2012 Blackwell Publishing Ltd.
