Abstract
OBJECTIVE To collect evidence on the rate of obesity in renal stone formers (RSFs) living in different climatic areas and consuming different diets. MATERIALS AND METHODS Data of adult renal stone formers were retrospectively collected by members of U-merge from 13 participant centers in Argentina, Brazil, Bulgaria (2), China, India, Iraq (2), Italy (2), Nigeria, Pakistan and Poland. The following data were collected: age, gender, weight, height, stone analysis and procedure of stone removal. RESULTS In total, 1689 renal stone formers (1032 males, 657 females) from 10 countries were considered. Average age was 48 (±14) years, male to female ratio was 1.57 (M/F 1032/657), the average body mass index (BMI) was 26.5 (±4.8) kg/m2. The obesity rates of RSFs in different countries were significantly different from each other. The highest rates were observed in Pakistan (50%), Iraq (32%), and Brazil (32%), while the lowest rates were observed in China (2%), Nigeria (3%) and Italy (10%). Intermediate rates were observed in Argentina (17%), Bulgaria (17%), India (15%) and Poland (22%). The age-adjusted obesity rate of RSFs was higher than the age-adjusted obesity rate in the general population in Brazil, India, and Pakistan, whereas it was lower in Argentina, Bulgaria, China, Italy, and Nigeria, and similar in Iraq and Poland. CONCLUSIONS The age-adjusted obesity rate of RSFs was not higher than the age-adjusted obesity rate of the general population in most countries. The relationship between obesity and the risk of kidney stone formation should be reconsidered by further studies carried out in different populations.

Prevalence of renal stones in Andalusian population: results of PreLiRenA study. Actas Urol Esp 2015; 39:26-31. [PMID: 24791620 DOI: 10.1016/j.acuro.2014.02.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2013] [Accepted: 02/02/2014] [Indexed: 11/24/2022]
Abstract
INTRODUCTION Urolithiasis is a disease having a high recurrence rate and associated morbidity. A not well quantified increase is being seen in recent years that could be related with various factors. The main purpose of our study has been to estimate urolithiasis prevalence and incidence in the region of Andalusia, determining which factors are associated. MATERIAL AND METHODS We performed an observational and cross-sectional study. Using a multistage randomized procedure, we selected a sample of 2439 subjects, aging from 40 to 65 years old, who currently lived in Andalusia. Data was collected through phone interviews, questioning the chosen subjects about their kidney stones history, comorbidity and socio-demographic characteristics. We conducted a descriptive, bivariate and multivariate analysis with logistic regression. RESULTS A total of 2439 subjects were surveyed. Subjects had mean age of 51.1±7.61 years - standard deviation; (95% confidence interval - 95% CI: 50.70-51.30), 48.7% of whom were male. Prevalence of urolithiasis obtained was 16.4% (95% CI: 14.87-17.85%) and an incidence of 1.2 (95% CI: .74-1.64). Variables significantly associated with the presence of urolithiasis found in the multivariate study were: presence of a family history of kidney stones (odds ratio -OR: 1.91; 95% CI: 1.51-2.40, P<.001), hypertension (OR:1.58; 95% CI:1.24-2.02; P<.001), gout (OR:1.98; 95% CI: 1.26-3,12; P=.003) and a high BMI (OR: 1.60; 95% CI 1.19-2.17; p=.008). CONCLUSIONS A significant increase in the prevalence and incidence of urolithiasis is observed in the environment in regards to the previously available figures. The presence of a family history of urolithiasis, hypertension, gout as well as having a high BMI could influence the observed epidemiological changes in renal lithiasis.
