[BDSP. Notice produite par INIST 53VnR0xZ. Diffusion soumise à autorisation]. Background. Reports on serum uric acid (SUA) levels in Chinese populations are sparse, but there is evidence that hyperuricaemia and gout are not uncommon. This paper characterizes SUA levels, their correlates, and their relationship to blood pressure (BP) and prevalent high blood pressure (HBP) for urban and rural adult population samples in north China. Methods. In 1987-1988, a cross-sectional study was carried out, using standardized methods, on men and women aged 40-58 in a Beijing area urban steel mill (N=2013) and on rural farms (1507). Main outcome measures were SUA, systolic and diastolic blood pressure (SBP, DBP), and prevalent HBP (SBP 140 or DBP 90 mmHg or receiving an antihypertensive drug). Results. Mean SUA levels for men were 5.75 mg/dl in urban and 5.58 mg/dl in rural settings ; for women, 4.67 and 4.48 mg/dl. Mean values were higher with age in women, but not in men. Age-standardized prevalence rates of HBP were significantly higher in upper SUA strata (men 7.00, women 6.00 mg/dl) than lower SUA strata both with and without inclusion of those on antihypertensive drugs. Mean SUA levels were correspondingly higher in hypertensive than non-hypertensive people. In multiple regression analyses, body mass index and serum triglycerides were strongly associated with SUA. Also SBP, DBP, and HBP were generally associated with SUA for the whole population sample, with smaller coefficients after excluding those on antihypertensive drugs. (...)
