RESUMO
AIMS/HYPOTHESIS: Cancer has contributed to an increasing proportion of diabetes-related deaths, while lifestyle management is the cornerstone of both diabetes care and cancer prevention. We aimed to evaluate the associations of combined healthy lifestyles with total and site-specific cancer risks among individuals with diabetes. METHODS: We included 92,239 individuals with diabetes but without cancer at baseline from five population-based cohorts in the USA (National Health and Nutrition Examination Survey and National Institutes of Health [NIH]-AARP Diet and Health Study), the UK (UK Biobank study) and China (Dongfeng-Tongji cohort and Kailuan study). Healthy lifestyle scores (range 0-5) were constructed based on current nonsmoking, low-to-moderate alcohol drinking, adequate physical activity, healthy diet and optimal bodyweight. Cox regressions were used to calculate HRs for cancer morbidity and mortality, adjusting for sociodemographic, medical and diabetes-related factors. RESULTS: During 376,354 person-years of follow-up from UK Biobank and the two Chinese cohorts, 3229 incident cancer cases were documented, and 6682 cancer deaths were documented during 1,089,987 person-years of follow-up in the five cohorts. The pooled multivariable-adjusted HRs (95% CIs) comparing participants with 4-5 vs 0-1 healthy lifestyle factors were 0.73 (0.61, 0.88) for incident cancer and 0.55 (0.46, 0.67) for cancer mortality, and ranged between 0.41 and 0.63 for oesophagus, lung, liver, colorectum, breast and kidney cancers. Findings remained consistent across different cohorts and subgroups. CONCLUSIONS/INTERPRETATION: This international cohort study found that adherence to combined healthy lifestyles was associated with lower risks of total cancer morbidity and mortality as well as several subtypes (oesophagus, lung, liver, colorectum, breast and kidney cancers) among individuals with diabetes.

OBJECTIVES: Only limited risk factors for ankylosing spondylitis (AS) have been identified to date. Therefore, we aimed to explore whether cardiovascular health (CVH) behaviours and factors are associated with the risk of developing AS. METHODS: Patients with incident AS were identified in cohorts from two ongoing prospective studies. Assessments were made of the association of AS with individual baseline cardiovascular health lifestyle behaviours (including smoking status, body mass index, physical activity and diet) and cardiovascular health factors (including total cholesterol levels, blood pressure levels and fasting plasma glucose levels), and with a cardiovascular health metric determined by the number of ideal behaviours and factors. Cox regression analysis was used for the estimation of hazard ratios (HRs) for AS. RESULTS: Among 124,303 participants, incident AS was identified in 53 individuals within the 8 years of follow-up. For participants with ideal physical activity (>80 min/week) the HR was 0.21 (95% CI 0.05-0.89) compared with participants without ideal physical activity after adjusting for potential confounders. No signi cant risk of developing AS was associated with baseline smoking, diet, body mass index, blood pressure, fasting blood glucose or total cholesterol status, nor did cardiovascular health metrics. CONCLUSIONS: Adherence to ideal physical activity may reduce the risk of developing AS.

BACKGROUND: Lung cancer is the most prevalent cancer, and the leading cause of cancer-related deaths in China. The aim of this study was to estimate the direct medical expenditure incurred for lung cancer care and analyze the trend therein for the period 2002-2011 using nationally representative data in China METHODS: This study was based on 10-year, multicenter retrospective expenditure data collected from hospital records, covering 15,437 lung cancer patients from 13 provinces diagnosed during the period 2002-2011. All expenditure data were adjusted to 2011 to eliminate the effects of inflation using China's annual consumer price index. RESULTS: The direct medical expenditure for lung cancer care (in 2011) was 39,015 CNY (US$6,041) per case, with an annual growth rate of 7.55% from 2002 to 2011. Drug costs were the highest proportionally in the total medical expenditure (54.27%), followed by treatment expenditure (14.32%) and surgical expenditure (8.10%). Medical expenditures for the disease varied based on region, hospital level, type, and stage. CONCLUSION: The medical expenditure for lung cancer care is substantial in China. Drug costs and laboratory test are the main factors increasing medical costs.
RESUMO
BACKGROUND AND AIM: This study aimed to clarify health-related quality of life (HRQoL) of patients with colorectal precancer and colorectal cancer (CRC) in China and to better understand related utility scores. METHODS: A hospital-based cross-sectional survey was conducted in precancer and CRC patients from 2012 to 2014, covering 12 provinces in China. HRQoL was assessed with EuroQol 5-Dimensions 3-Levels. Utility scores were derived using Chinese value set. A multivariate regression model was established to explore potential predictors of utility scores. RESULTS: A total of 376 precancer (mean age 58.7 years, 61.2% men) and 2470 CRC patients (mean age 58.6 years, 57.6% men) were included. In five dimensions, there was a certain percentage of problem reported among precancer (range: 12.0% to 36.7%) and CRC (range: 32.4% to 50.3%) patients, with pain/discomfort being the most serious dimension. Utility scores of precancer and CRC patients were 0.870 (95% confidence interval [CI], 0.855-0.886) and 0.751 (95% CI, 0.742-0.759), both of which were lower than those of general Chinese population (0.960 [95% CI, 0.960-0.960]). Utilities for patients at stage I to stage IV were 0.742 (95% CI, 0.715-0.769), 0.722 (95% CI, 0.705-0.740), 0.756 (95% CI, 0.741-0.772), and 0.745 (95% CI, 0.742-0.767), respectively. Multivariate analysis showed that therapeutic regimen, time point of the interview, education, occupation, annual household income, and geographic region were associated with utilities of CRC patients. CONCLUSION: Health-related quality of life of both precancer and CRC patients in China declined considerably. Utility scores differed by sociodemographic and clinical characteristics, and findings of these utilities may facilitate implementation of further cost-utility evaluations.

BACKGROUND: The association between blood pressure change and kidney damage in patients with abnormal blood glucose remains unclear. The current study aimed to identify systolic blood pressure (SBP) trajectories among the prediabetic population and to determine their association with kidney damage after a long-term follow-up. METHODS: The incidence, development, and prognosis of diabetic kidney disease (INDEED) study is nested in the Kailuan cohort study with a focus on population with diabetes and prediabetes. We screened out people with prediabetes in 2006 and with more than three SBP records from 2006 to 2014 biennially. We used the latent mixture modeling to fit five groups of trajectories of SBP. In 2016, estimated glomerular filtration rate (eGFR), urinary albumin creatinine ratio (uACR), and urinary α1-microglobulin (α1MG), transferrin and α1-acid glycoprotein were measured, and the association between SBP trajectories and these markers was analyzed by linear regression and logistic regression models. RESULTS: Totally, 1451 participants with prediabetes and without kidney damage were identified in 2006. Five heterogeneous SBP trajectories were detected based on the longitudinal data from 2006 to 2014, as low-stable group (n = 323), moderate-stable group (n = 726), moderate-increasing group (n = 176), moderate-decreasing group (n = 181), and high-stable group (n = 45). Linear regression analysis showed that the moderate and high SBP groups had lower eGFR, higher uACR, higher urinary α1MG, higher transferrin, and higher α1-acid glycoprotein than the low-stable group. Multivariable analysis attenuated the association but did not change the statistical significance. CONCLUSIONS: Prediabetic patients with persistent high-level SBP trajectory or gradually increased SBP trajectory had severer kidney damage during follow-up.

BACKGROUND: In diabetic kidney disease (DKD), it is important to find biomarkers for predicting initiation and progression of the disease. Besides glomerular damage, kidney tubular injury and inflammation are also involved in the development of DKD. The current study investigated the associations of urinary epidermal growth factor (uEGF), monocyte chemotactic protein-1 (MCP-1) and the uEGF:MCP-1 ratio with kidney involvement in patients at early and advanced stages of DKD. METHODS: The concentration of uEGF and uMCP-1 was measured in two Chinese population-based studies. The associations of uEGF, uMCP-1 and uEGF/MCP-1 with occurrence of DKD were studied in a cross-sectional study (n = 1811) of early stage DKD. Associations of baseline uEGF, uMCP-1 and uEGF/MCP-1 with kidney outcome were assessed in a longitudinal cohort (n = 208) of advanced-stage DKD. RESULTS: In both studies, positive correlations were found between uEGF/urine creatinine (Cr) and estimated glomerular filtration rate (eGFR) at sampling and between uMCP-1/Cr and urinary albumin:creatinine ratio (uACR). In the cross-sectional study, uEGF/Cr and uEGF/MCP-1 were negatively associated with the occurrence of DKD {odds ratio (OR) 0.65 [95% confidence interval (CI) 0.54-0.79], P < 0.001; 0.82 (0.71-0.94), P = 0.005, respectively}. In the longitudinal cohort, the uEGF:MCP-1 ratio correlated more closely with the percentage change of eGFR slope (r = 0.33, P < 0.001) as compared with uEGF/Cr or uMCP-1/Cr alone. The composite endpoint was defined as end-stage renal disease or 30% reduction of eGFR. These three markers were independently associated with composite endpoint after adjusting for potential confounders [hazard ratio 0.76 (0.59-1.00), P = 0.047 for uEGF/Cr; 1.18 (1.02-1.38), P = 0.028 for uMCP-1/Cr; 0.79 (0.68-0.91), P = 0.001 for uEGF/MCP-1]. CONCLUSION: In Chinese patients, urinary EGF/MCP-1 was negatively associated with the occurrence of DKD. Moreover, uEGF/MCP-1 had a better ability to predict the composite endpoint and correlated more closely with kidney function decline in advanced DKD as compared with uEGF/Cr or uMCP-1/Cr alone.

PURPOSE: To investigate microvascular abnormalities in diabetic patients without conventional clinical signs of diabetic retinopathy (DR). METHODS: In this cross-sectional observational cohort study, the study group included randomly chosen participants of a community-based cohort with diabetes type 2 without DR, and the control group consisted of non-diabetic individuals from a population-based study. All participants underwent optical coherence tomographic angiography (OCTA). RESULTS: Upon OCTA, 118 (40.4%) eyes of the study group (n = 292 eyes) showed microvascular abnormalities including foveal avascular zone erosion (95 (32.5%) eyes), non-perfusion areas in the superficial and deep retinal layers (39 (13.4%) eyes and 19 (6.5%) eyes, respectively), and microaneurysms in the superficial and deep retinal layers (22 (7.5%) eyes and 31 (10.6%) eyes, resp.). None of these abnormalities was detected in the control group (n = 80). The study group showed a lower vessel density in the superficial retinal vascular layer in all regions except for the foveal region (P < 0.001), and higher vessel density in the parafoveal region in the deep retinal vascular layer (P = 0.01). Higher diabetes prevalence was associated with lower superficial retinal vascular density (P = 0.005) in multivariable analysis. A lower radial peripapillary capillary flow density was correlated (regression coefficient r, 0.62) with higher fasting blood concentration of glucose (P < 0.001) in multivariable analysis. CONCLUSIONS: OCTA revealed microvascular abnormalities in 40% of eyes of diabetic patients without ophthalmoscopically detectable diabetic fundus changes in a community-based population. The early stage of DR may be re-defined upon OCTA.

OBJECTIVE: The impact of participating in breast cancer screening programmes on health-related quality of life (HRQoL)is poorly understood. METHODS: Based on a national breast cancer screening programme in China, a multicentre cross-sectional survey was conducted covering 12 provinces from September 2013 to December 2014. HRQoL of participants in the screening population and general population was evaluated by the three-levelEuroQol-five-Dimensions (EQ-5D-3L) instrument, and utility scores were generated through the Chinese value set. Univariate and multivariate regression analyses were performed to explore determinants of utility scores and anxiety/depression problems. RESULTS: For screening group and general population (n = 4756, mean age = 51.6 year old), the corresponding utility scores were 0.937 (95% CI, 0.933-0.941) and 0.953 (0.949-0.957) (P < .001). Pain/discomfort and anxiety/depression were the most common reported in both groups (51.4% and 34.3%, P < .001). Utility scores at prescreening, in-screening, and postscreening interview timings were 0.928 (0.921-0.935), 0.958 (0.948-0.969), and 0.938 (0.933-0.943), respectively (P < .001); the corresponding proportions of anxiety/depression reporting were 25.9%, 16.3%, and 21.1%, respectively (P = .004). Interview timing, geographical region, and insurance status were associated with HRQoL and anxiety/depression in women at high-risk of breast cancer. CONCLUSIONS: Utility scores of screening participants were significantly lower than that of general population in China, but the difference may be clinically insignificant. Further cohort studies using HRQoL measurements are needed.

This prospective study included 68,759 Chinese male adults from Kailuan cohort of China who had a standardized medical examination between 2006 and 2007 and were followed up for approximately 8 years until occurrence of ASCVD, cancer or death or until December 31, 2014. Subjects were divided into four categories based on the quartiles of TC, LDL-C and non-HDL-C. Cox regression models were used to estimate hazard ratios (HRs) and their 95% confidence intervals (CIs). During follow-up, 2,916 males developed ASCVD and 1,884 developed cancer. Compared with the lowest quartile, the upper-most quartiles of TC, LDL-C and non-HDL-C were all associated with increased ASCVD risk (HR 1.53; HR 1.16; HR 1.55); however, the upper-most quartiles of TC, LDL-C and non-HDL-C were all negatively associated with cancer (HR0.84; HR 0.82; HR 0.80) and these associations were present after exclusion of incident cancers during the first 4 years of follow-up. In a word, we report that high TC, LDL-C and non-HDL-C concentrations increased ASCVD incidence in a male population and that these lipid profiles were inversely associated with total cancer and several individual cancers.

BACKGROUND: With the marked increase in the prevalence of diabetes mellitus, it was the purpose of our study to assess a potential association of time-cumulated exposure to systolic (CumSBP) and of diastolic blood pressure (CumDBP) with onset of impaired glucose tolerance and diabetes mellitus. METHODS: The prospective investigation included participants of the longitudinal Kailuan Study with three baseline examinations in 2006-2007, 2008-2009 and 2010-2011, re-examination in 2012-2013, and no diabetes mellitus at baseline. Cumulative blood pressure (BP) was calculated as cumBP = [(BP1 + BP2)/2 × time1-2] + [(BP2 + BP3)/2 × time2-3]. Based on cumSBP, the study population was stratified into four groups (cumSBP < 480mmHgxyear;n = 15,339; 480mmHgxyear ≤ cumSBP < 520mmHgxyear;n = 7214; 520mmHgxyears ≤ cumSBP < 560mmHgxyears;n = 5675; and cumSBP ≥ 560mmHgxyears;n = 10,576). RESULTS: After adjusting for demographic, anthropomorphic, biochemical, socioeconomic and lifestyle parameters and as compared with the first group, the second, third and fourth group showed a significantly higher incidence of diabetes (P-trend < 0.001;hazard ratio (HR);95% confidence interval (CI):1.28(1.08,1.51),1.54(1.29,1.84), and 2.33(1.98,2.73), respectively), higher incidence of impairment of glucose tolerance (P-trend < 0.001;HR;95% CI1.17(1.02,1.33), 1.43(1.25,1.64), and 2.09(1.85,2.37), respectively), and higher incidence of diabetes developing out of an impairment of glucose tolerance (P-trend < 0.001;HR;95% CI:1.22(0.97,1.54),1.47(1.16,1.86), and 2.01(1.62,2.50), respectively). An increase in cumSBP by 10 mmHg/year or an increase in cumDBP by 5 mmHg/year was associated with a hazard ratio of incident diabetes of 1.04 (95% CI:1.03,1.04) and 1.02(1.02,1.03), respectively, with a hazard ratio of incident impairment of glucose tolerance of 1.04(95% CI:1.03,1.04) and 1.03(95% CI:1.02,1.03), respectively, and with a hazard ratio of incident diabetes developing from impairment of glucose tolerance of 1.04(95% CI:1.03,1.04) and 1.03(95% CI:1.02,1.03), respectively. CONCLUSIONS: Time-cumulated exposure to elevated blood pressure was significantly associated with an elevated incidence of impaired glucose tolerance and diabetes.

OBJECTIVE: Although sleep is one of the most important health-related behavioral factors, the association between night sleep duration and cognitive impairment has not been fully understood. A cross-sectional study was conducted with a random sample of 2,514 participants (â 40 years of age; 46.6% women) in China to examine the association between night sleep duration and cognitive impairment. METHODS: Night sleep duration was categorized as â 5, 6, 7, 8, or â 9 h per night. Cognitive function was measured using the Mini-Mental State Examination. A multivariate regression analysis was used to analyze the association of night sleep duration with cognitive impairment. A total of 122 participants were diagnosed with cognitive impairment. RESULTS: A U-shaped association between night sleep duration and cognitive impairment was found. The odds ratios (95% confidence intervals) of cognitive impairment (with 7 h of daily sleep being considered as the reference) for individuals reporting â 5, 6, 8, and â 9 h were 2.14 (1.20-3.83), 1.13 (0.67-1.89), 1.51 (0.82-2.79), and 5.37 (1.62-17.80), respectively (P â 0.01). CONCLUSION: Short or long night sleep duration was an important sleep-related factor independently associated with cognitive impairment and may be a useful marker for increased risk of cognitive impairment..

OBJECTIVE: To investigate the effects of physical activity (PA) on dyslipidemia and elevated resting heart rate (RHR) in a large-scale cross-sectional study in China. METHODS: We recruited community-based individuals who were 40-60 years old using a cluster sampling method. The PA levels of the participants were classified as low, moderate, or high, using the International Physical Activity Questionnaire. Dyslipidemia was defined as the detection of abnormalities in lipid indicators, and 4 lipid parameters were evaluated using fasting blood samples. Multivariate logistic regression analyses were used to evaluate the associations of PA with dyslipidemia and RHR. RESULTS: A total of 10,321 participants (38.88% men) were included in this study. The percentages of individuals with high, moderate, and low PA levels were 46.5%, 43.9%, and 9.6%, respectively. In both men and women, high PA provided odds ratios of 0.88 [95% confidence interval (CI): 0.83, 0.94] for dyslipidemia and 0.82 (95% CI: 0.73, 0.92) for elevated RHR, compared to participants with low PA. CONCLUSION: Our data suggested that substantial health benefits (related to dyslipidemia and elevated RHR) occurred at higher intensity PA, with greater energy consumption, in middle-aged Chinese people, and particularly in men.

The morbidity and mortality of cardiovascular disease (CVD) rank first among common diseases. Arteriosclerosis and diabetes are risk factors for CVDs, which influence each other. However, their combined effects on CVDs are still unclear. In this study, people who participated in brachial-ankle pulse wave velocity (baPWV) testing and the annual physical examination of the Kailuan Group Finance Co., Ltd., from January 1, 2010, to December 31, 2020, were selected, and their anthropometric, biochemical and epidemiological data were collected. The participants were divided into four groups according to diabetes and arteriosclerosis diagnosis and follow-up. Cox proportional hazards regression and subdistribution hazard models were used to analyse the combined effects of arteriosclerosis and diabetes on CVDs. Multiple sensitivity analyses were also performed. A total of 59,268 Asian populations were selected, including 14,425 females (28.11%) with an average age of 48.10 (± 12.72) years. During follow-up, 1830 subjects developed CVDs (mean follow-up period, 4.72 years). The cumulative incidence rates of the healthy control, diabetes, arteriosclerosis, and comorbidity groups were 5.04% (807/38781), 15.17% (253/3860), 17.04% (465/5987), and 25.59% (305/2684), respectively. The results of multivariate Cox regression analysis showed that compared with the healthy control group, the risk of CVD in the diabetes, arteriosclerosis, and comorbidity groups was significantly increased. Their HR values were 1.88 (95% CI 1.62-2.18), 1.40 (95% CI 1.23-1.60), and 2.10 (95% CI 1.80-2.45), respectively. The results of the sensitivity analysis were robust. For each one standard increase in fasting blood glucose or baPWV, the HR values for CVDs were 1.16 (95% CI 1.12-1.20) and 1.22 (95% CI 1.16-1.28), respectively. The results indicated that both arteriosclerosis and diabetes lead to an increased risk of CVDs. The risk of CVDs, coronary atherosclerotic heart disease, heart failure, stroke, coronary artery bypass grafting and ischemic stroke in patients with arteriosclerosis and diabetes was significantly higher than that in patients with arteriosclerosis or diabetes alone. Therefore, the primary prevention of CVDs in patients with arteriosclerosis complicated with diabetes needs more attention.

Objective: Cognitive impairment (CI) in older individuals has a high morbidity rate worldwide, with poor diagnostic methods and susceptible population identification. This study aimed to investigate the relationship between different retinal metrics and CI in a particular population, emphasizing polyvascular status. Methods: We collected information from the Asymptomatic Polyvascular Abnormalities Community Study on retinal vessel calibers, retinal nerve fiber layer (RNFL) thickness, and cognitive function of 3,785 participants, aged 40 years or older. Logistic regression was used to analyze the relationship between retinal metrics and cognitive function. Subgroups stratified by different vascular statuses were also analyzed. Results: RNFL thickness was significantly thinner in the CI group (odds ratio: 0.973, 95% confidence interval: 0.953-0.994). In the subgroup analysis, the difference still existed in the non-intracranial arterial stenosis, non-extracranial carotid arterial stenosis, and peripheral arterial disease subgroups ( P < 0.05). Conclusion: A thin RNFL is associated with CI, especially in people with non-large vessel stenosis. The underlying small vessel change in RNFL and CI should be investigated in the future.

The characteristics of early-onset (onset age <50 years) and later-onset (onset age â½ 50 years) cancers differ significantly. Identifying novel risk factors for both types of cancer is crucial for increasing awareness of cancer prevention and for reducing its burden. This study aimed to analyze the trends in incidence and risk factors for early-onset and late-onset cancers. We conducted a prospective study by drawing data from the Kailuan Study. This study included 6,741 participants with cancer (624 with early-onset cancer and 6,117 with later-onset cancer) and 6,780 matched controls among the 186,249 participants who underwent Kailuan health examinations from 2006 to 2019. The primary outcomes were cancer incidence rates, and associated risk factors for early- and later-onset cancer. Weighted Cox regression was used to calculate hazard ratios and 95% confidence intervals of each exposure factor for early- and later-onset cancer by cancer type. Population-attributable risk proportions were used to estimate the number of cases that could be prevented by eliminating a risk factor from the population. Except for liver cancer, incidence rates for nearly all types of cancer increased during the study period. Smoking, alcohol consumption, lipid metabolism disorders, hypertension, diabetes mellitus, fatty liver, and inflammation were associated with a significantly increased risk of cancer at multiple sites, but risk factors for cancer incidence differed by site. Smoking, alcohol consumption, inflammation, and hypertension were the major contributors to preventable cancer. The incidence of several different types of cancer, including early-onset cancer, is increasing in northeastern China. Differences in risk factors between early-onset and later-onset malignancies may contribute to the divergence in the observed changes in incidence trends between these two specific types of cancer.

OBJECTIVE: To explore the impact of the waist circumference change on new onset diabetes (NOD) in the impaired fasting glucose (IFG) population. METHODS: A total of 12 657 subjects who took part in the health examination from 2006 to 2007 and from 2010 to 2011 from the employees of Kailuan Group and met the inclusion criteria were selected as the observation cohort.Of the 12 657 subjects, 10 697 were male, 1960 were female, with age of (49.9 ± 11.3) years old. According to the baseline waist circumference (WC) measurements and its quartile in the health examinations during 2006 to 2007, the observation population was divided into four groups (first, second, third and the fourth quartile groups) . Multiple logistic regression analysis was used to test the relation between the increasing of WC and NOD. RESULTS: The incidences in the IFG population of NOD were 4.27% (1884/12 657) in the total population;4.25% (1581/10 697) in male and 4.44% (303/1960) in females, respectively (P < 0.05) . Along with increasing WC in the 4 quartile groups, the incidences of NOD was progressively increased, which were 2.19% (235/3083) , 3.07% (333/3114) , 4.47% (473/3037) and 7.08% (843/3423) , respectively;2.34% (213/2626) , 3.06% (282/2645) , 4.37% (393/2582), 7.00% (693/2844) in males and 1.38% (22/457) , 3.12% (51/469) , 5.05% (80/455) , 7.45% (150/579) in female (P < 0.05) . Multiple logistic regression analysis showed that compared with the first quartile group, the second, third and fourth quartile group had increased risk of NOD after adjusting for age, gender and other risk factors, the OR (95%CI) values were 1.38(1.13-1.68), 1.79 (1.47-2.09) and 3.10 (2.57-3.75), respectively. CONCLUSION: The incidence of NOD in the IFG population increased as the WC increased.

OBJECTIVE: To investigate the significance of high sensitivity C-reactive protein (hsCRP) levels in serum for detecting type 2 diabetes mellitus (T2DM) patients at risk of developing nonalcoholic fatty liver (NAFLD). METHODS: Individuals with T2DM (n = 9489) were recruited from the Kailuan Company between 2006 and 2007 for the first phase of this community-based prospective cohort study. For the second phase of the study, the original cohort was recruited for follow-up (at two years from each subject's original enrollment date (baseline)). The total followed-up subjects (n = 2802; 2344 males, 458 females, 22-88 years old) were categorized into quartiles according to baseline measurements of serum hsCRP levels (less than or equal to 0.30, > 0.30-0.60, > 0.60-1.92 and > 1.92 mg/L) and used to determine the relationship between change in incidence rates of NAFLD and predictive value of baseline serum hsCRP levels by logistic regression analysis. RESULTS: Twenty-nine percent (n = 813) of the followed-up subjects developed NAFLD. The incidence (%) of NAFLD at the two-year follow-up had increased in conjunction with the level of serum hsCRP detected at baseline (quartile 1: 22.5%, 2: 27.3%, 3: 32.1%, and 4: 34.3%; all, P less than 0.01). It was found that the subjects in the highest quartile had an increased risk of NAFLD (odds ratio (OR) = 1.80, 95% confidence interval (CI): 1.42-2.28, P less than 0.01), as compared with those in the lowest quartile. Moreover, when the regression model was adjusted for baseline factors of age, sex, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting serum glucose, and body mass index, the risk of NAFLD remained significantly higher for the highest quartile (vs. the lowest quartile; OR = 1.49, 95% CI: 1.16-1.91, P less than 0.01). CONCLUSION: Serum hsCRP levels may be predictive of development of NAFLD in individuals with type 2 diabetes mellitus. The risk of NAFLD increases in parallel with increasing levels of serum hsCRP.

OBJECTIVE: To explore the association between blood pressure level and incidence of carotid arterial plaque in middle-aged and elderly people. METHODS: A total of 5852 individuals were randomly stratified from the 101 510 health examination survey participants in Tangshan Kailuan Company community during 2006-2007. A total of 5440 people (age above 40 years old, free of stroke, TIA and myocardial infarction) were enrolled in the final analysis. A questionnaire survey, blood biochemical analysis and carotid artery ultrasound examination were finished by trained medical staff. Sixteen individuals without carotid artery plaques information and 35 individuals without blood pressure information were excluded. Finally, a total of 5389 participants [3235 male, mean age: (54.7 ± 11.8) years] were analyzed. According to 2010 Chinese guideline to prevention and treatment of hypertension and blood pressure level classification, participants were divided into normotensive group (n = 1377), high normal blood pressure group (n = 1971) and hypertensive group (n = 2041). Multivariate logistic regression analysis was used to determine the risk factors of the carotid artery plaques. RESULTS: Age, male gender, BMI, IMT, TG, FBG, smoking and alcohol drinking rate were significantly higher in high normal blood pressure group than in normotensive group (all P < 0.05), LDL-C, HDL-C, hs-CRP and TC were similar between these two groups. Incidence of carotid artery plaques in normotensive, high normal blood pressure and hypertensive groups was 24.8%, 37.4%, 60.2% respectively. The risk of carotid artery plaques was increased to 38% and 163% in high normal and hypertensive groups compared to normotensive group, the OR ratio was 1.38 (95%CI: 1.15-1.66) and 2.63 (95%CI: 2.18-3.18), respectively. After adjusting gender, age, smoking, alcohol consumption, TG, TC, HDL-C, FBG, hs-CRP and BMI, the risk of developing carotid artery plague was increased in proportion to increasing blood pressure and the OR value was 1.24 (95%CI:1.01-1.52) , 1.69 (95%CI:1.34-2.15) and 2.66 (95%CI:2.20-3.21) in high normal group I [SBP/DBP 121-129/80-84 mm Hg(1 mm Hg = 0.133 kPa)] and high normal group II (SBP/DBP 130-139/85-89 mm Hg) and hypertensive group, respectively. CONCLUSIONS: The cardiovascular risk factors and prevalence of carotid artery plague increase in proportion to blood pressure level in this cohort. The detection rate of carotid artery plague is already significantly increased in individuals with high normal blood pressure.

OBJECTIVE: To investigate the impact of resting heart rate (RHR) on new-onset diabetes (NOD) in population without hypertension. METHODS: This prospective cohort study was performed in 2006 and 2007 and screened 101 510 participants. All subjects were employees of the Kailuan Group, a state-run coal mining company. The observation cohort included 48 926 subjects with normal fasting blood glucose (FBG) <7.0 mmol/L, no history of diabetes, complete FBG and RHR examination data, systolic blood pressure <140 mm Hg (1 mm Hg = 0.133 kPa) , diastolic blood pressure <90 mm Hg, no history of hypertension, and no use of hypoglycemic agents or antihypertensive drugs.We excluded participants without a health examination in 2008-2009 or 2010-2011 and those with incomplete examination data. A total of 29 910 participants were included in the final analysis. The observation population was divided into four groups according to RHR data collected during 2006-2007 health examinations: quartile 1 (RHR<63 beats/min) ; quartile 2 (63 beats/min ≤ RHR<70 beats/min) ; quartile 3 (70 beats/min ≤ RHR<75 beats/min) ; quartile 4 ( RHR ≥ 75 beats/min). Kaplan-Meier analysis was used to calculate the incidence of NOD. The relationship between RHR and NOD was estimated using Cox proportional hazard analysis. RESULTS: The incidences of NOD/1000 person-years for the above quartiles of RHR were 11.22, 13.58, 13.96, and 17.55, respectively in the total observational population; the corresponding incidences were 12.17, 15.20, 16.08, 20.44, and 8.29, 9.38, 8.86, and 9.60 in men and women, respectively. Compared with quartile 1, Cox proportional hazard regression analysis showed that the other three RHR groups had an increased risk of NOD after adjusting for age, gender, systolic blood pressure, diastolic blood pressure, and other risk factors. The hazard ratio values for these groups were 1.20 (95%CI:1.04-1.40, P < 0.05), 1.25 (95%CI:1.07-1.45, P < 0.01) and 1.58 (95%CI:1.36-1.82, P < 0.01), respectively. Furthermore, after adjusted the FBG, risk of NOD was significantly higher in quartile 2 (HR = 1.21, 95%CI:1.04-1.40, P < 0.01) and quartile 4 (HR = 1.22, 95%CI:1.06-1.41, P < 0.01 compared that in quartile 1. After adjusting for the factors listed above, the influence of RHR on NOD was not significant in women (P > 0.05) , but there was still an increased risk of NOD in men compared with quartile 1 with hazard ratio values of 1.21 (95%CI:1.02-1.43, P < 0.05) , and 1.27 (95%CI:1.09-1.49, P < 0.01) for quartile 2 and quartile 4, respectively. CONCLUSION: Higher RHR is linked with higher risk of NOD in population without hypertension.
