Background Gouty patients are commonly supposed to have unhealthy lifestyle habits. Recent studies have focused on the importance of the intervention on lifestyle factors for the prevention of gout in the spectrum of the metabolic syndrome .
Objectives To compare lifestyle habits of a random sample of patients with gout in rheumatologic setting to official data on general population of Italy.
Methods Data were extracted from the dataset of an ongoing multicentre cohort study including patients with prevalent clinically diagnosed gout (Kick-off of the Italian Network for Gout, KING, sponsored by SIR), recruited from June 2011 and January 2012 from 30 rheumatology practices across Italy. Socio-demographic data and lifestyle habits were systematically collected in order to measure indicators consistent with available national surveys. Last available national data were retrieved from the 2010 release of the Health for All , stratifying for the maximum level of detail in terms of gender, classes of age and region.
Analyzed variables included: employment status (employed vs. unemployed), educational level (high school degree), obesity (body mass index ≥30), smoking (current smokers), wine consumption (>0.5 l/day), beer consumption (usual drinker), beef meat, sausages, pork meat and fish intake (sometimes in a week), and vegetables intake (≥1 portion/day).
The relative increase of exposure in gouty patients was estimated by standardized prevalence ratios, taking into count gender, age and geographical distribution. Results are presented as standardized prevalence ratio [95% confidence intervals, CI].
Results The study population included 450 patients (M:F ratio of 9:1, mean (SD) age of 63.7 (11.6) years and median (IQR) disease duration of 3.4 (1.4-9.7) years).
Compared to general population, gouty patients showed a lower employment rate (0.46 [CI 0.43, 0.49]) and a lower prevalence of high school education (0.77 [CI 0.73, 0.80]), indicating lower socio-economic status. A higher prevalence of obesity (1.85 [CI 1.64, 2.06]), a lower prevalence of smoking (0.49 [CI 0.74, 0.94]) and a higher prevalence of wine (2.23 [CI 1.45, 3.01]) and beer (3.07 [CI 1.58, 4.55]) consumption was also observed. Further, gouty patients consumed less beef meat (0.78 [CI 0.75, 0.82]), more sausages (1.08 [CI 1.06, 1.10]), less pork meat (0.73 [CI 0.72, 0.75]), more vegetables (1.57 [CI 1.53, 1.61]) and a similar amount of fish (0.99 [CI 0.96, 1.03]) than Italian general population.
Conclusions Gout is clearly no longer associated with a higher socio-economic status, but gouty patients’ lifestyle is still far different from the recommended. Further efforts should be put in each level of prevention for lifestyle modification.
