legacy of the tehran lipid and glucose study: chronic kidney disease

Context: chronic kidney disease (ckd), is correlated with a substantial upsurge in mortality and morbidity worldwide. in this review, we aimed to review the 20-year-findings on ckd of the tehran lipid and glucose study (tlgs). evidence acquisition: we conducted a systematic review of all studies on ckd that had been performed in the context of tlgs. results: age adjusted prevalence of ckd, according to estimated glomerular filtration rate (egfr) assessed with the two abbreviated equations of the modification of diet in renal disease (mdrd) and the ckd epidemiology collaboration (ckd-epi) were 11.3% (95% confidence interval (ci): 10.7, 12.0) and 8.5% (95% ci: 7.9, 9.1), respectively. using mdrd equation, over a mean follow up of 9.9 years, the incidence density rates of ckd were 285.3 person years in women and 132.6 per 10000 person-years in men. studies on the tlgs population documented that abdominal adiposity defined as waist circumference (wc) categories (p for trend < 0.02) and waist gain in men (hazard ratio (hr) = 1.7, ci: 1.3, 2.2) significantly affected ckd development. also, ckd had a significant effect on coronary heart disease (chd) only in participants with low body mass index (hr = 2.06; ci: 1.28, 3.31 and hr = 2.56; ci: 1.04, 6.31 in men and women, respectively). moreover, ckd was among the strongest independent predictors of stroke (hr = 2.01, ci: 1.22, 3.33). also, compared to diabetic patients, an abnormal ecg was more prevalent in moderate ckd (p = 0.02). conclusions: increased waist circumference and waist gain (only in men) were associated with developing ckd in the tlgs population. ckd was an independent predictor of chd (in lean individuals) and stroke.
