INTRODUCTION In China, population-based blood pressure levels and prevalence of hypertension are increasing. Meanwhile, sodium intake, a major risk factor for hypertension, is high. In 2011, to develop intervention priorities for a salt reduction and hypertension control project in Shandong Province (population 96 million), a cross-sectional survey was(More)
The association of 24 h urinary Na and potassium excretion with the risk of the metabolic syndrome (MetS) has not been studied in China. The aim of the present study was to examine this association by analysing the data from 1906 study participants living in north China. To this end, 24 h urine samples were collected. Of the 1906 participants, 471 (24·7 %)(More)
OBJECTIVE To describe dietary sodium intakes and resources among residents in Shandong province. METHODS A total of 2184 subjects were selected by multi-stage stratified cluster random sampling method from 18-69 years old people in Shandong province in June, 2011. A total of 2140 subjects completed the study, the completion rate was 98.0%. Three-day(More)
BACKGROUND Microalbuminuria has been shown to be a risk factor for cardiovascular and renal disease in patients with hypertension and diabetes as well as in the general population. Urinary albumin excretion over 24 h is considered a 'gold standard' to detect microalbuminuria. Few studies have used 24-h urinary albumin excretion to analyze the prevalence of(More)
This study examined the impact of overweight/obesity on sodium, potassium, and blood pressure associations using the Shandong-Ministry of Health Action on Salt Reduction and Hypertension (SMASH) project baseline survey data. Twenty-four-hour urine samples were collected in 1948 Chinese adults aged 18 to 69 years. The observed associations of sodium,(More)
OBJECTIVE To examine the association of 24 h urinary Na excretion and Na:K with obesity in Chinese adults. DESIGN Population-based cross-sectional study using a four-stage stratified sampling strategy. SETTING Shandong Province, China. SUBJECTS Chinese adults (n 1906) aged 18-69 years who provided complete 24 h urine samples. RESULTS Odds of obesity(More)
BACKGROUND/AIMS High sodium intake and low intake of potassium can increase blood pressure (BP) and risk of developing hypertension. Few studies have examined the association between 24-h urinary sodium and potassium excretion and BP or risk of hypertension in China, and most used only a single 24-h urinary sample. METHODS We analyzed data on 2281(More)
OBJECTIVE To explore the knowledge, attitude and behavior of salt reduction among Chinese adults aged over 18 years old in 2010. METHODS A total of 96 916 adults aged over 18 were recruited from 162 surveillance points in 2010, applying multi-stage stratified cluster random sampling method.Information about subjects salt reduction related knowledge,(More)
OBJECTIVE To compare the difference and correlation between dietary salt intakes assessed by 24 hours urinary Na method, food weighted record method and food frequency questionnaire method. METHODS All 2 184 subjects aged 18 to 69 were selected by multi stage stratified cluster random sampling method in Shandong province in June to September, 2011.(More)
The aim of the study was to estimate the urinary electrolyte excretion and assess the relationship between dietary sodium or potassium intake and blood pressure within a population of 18-69 adults in Shandong province, China. Random samples of 2184 adults enrolled in the Shandong and Ministry of Health Action on Salt reduction and Hypertension project were(More)
