To the Editor： Nonarteritic anterior ischemic optic neuropathy （NAION） is an acute optic neuropathy disease that is common in the elderly. The incidence of NA1ON is approximately （2.3-10.2）/100,000, and both eyes are involved in many patients. Xu et al. reported that the incidence in the Chinese population was 1/16,000. Acute visual acuity （VA） damage without any pain and a poor prognosis are the main features of NAION. This study aimed to find the related risk factors for NAION in average individuals to promote the prevention or early diagnosis of NAION.

目的探讨不同血压分层对糖尿病人群肾功能的影响。方法采用前瞻性队列研究设计,以2006年7月-2007年10月参加健康查体的101510名开滦集团职工中9489例糖尿病患者作为观察队列,随访(8.6±4.0)年。依据基线血压水平将研究人群分为正常血压(收缩压<120 mmHg、舒张压<80 mmHg)、血压升高(收缩压120~130 mmHg、舒张压<80 mmHg)、高血压1级[收缩压130~140 mmHg和(或)舒张压80~90 mmHg]、高血压2级[收缩压≥140 mmHg和(或)舒张压≥90 mmHg]4组。比较各组人群的慢性肾脏病(CKD)的发病密度。采用多变量Cox比例风险回归模型分析不同血压对糖尿病人群肾功能的影响,采用多变量时间依赖性Cox比例风险模型分析结果的稳定性,并排除随访期间发生心血管事件(CVD)、基线服用降压药和基线服用降糖药后进行敏感性分析。结果(1)在基线水平,高血压1级组患者年龄、体重指数(BMI)高于正常血压组患者,差异有统计学意义(P<0.05)。(2)至随访结束时,发生CKD 2294例,其中估算肾小球滤过率(eGFR)下降1117例,尿蛋白1575例,高血压1级组CKD的发病密度为39.4/千人年,eGFR下降发病密度为16.3/千人年,尿蛋白发病密度为25.5/千人年,与正常血压组比较差异均有统计学意义(log-rank检验,P<0.01)。(3)多因素Cox比例风险回归模型分析显示,与正常血压比较,高血压1级可使糖尿病人群发生CKD的风险增加29%(HR=1.29,95%CI 1.09~1.52)、eGFR下降的风险增加40%(HR=1.40,95%CI 1.08~1.80)。结论高血压1级(≥130/80 mmHg)即可增加糖尿病人群发生CKD和eGFR下降的风险,且eGFR下降的风险更大。

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 （≥ 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 ≤ 5, 6, 7, 8, or ≥ 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 ≤ 5, 6, 8, and ≥ 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 ≤ 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.

Background: Several recent genome-wide association studies suggested insomnia and anemia may share some common genetic components. We thus examined whether adults with anemia had higher odds of having insomnia relative to those without anemia in a cross-sectional study and a ***: Included in this cross-sectional study were 12,614 Chinese adults who participated in an ongoing cohort, the Kailuan Study. Anemia was defined as hemoglobin levels below 12.0 g/dL in women and 13.0 g/dL in men. Insomnia was assessed using the Chinese version of the Athens Insomnia Scale (AIS). A total AIS score ≥6 was considered insomnia. The association between anemia and insomnia was assessed using a logistic regression model, adjusting for potential confounders such as age, sex, chronic disease status, and plasma C-reactive protein concentrations. A meta-analysis was conducted using the fixed effects model to pool results from our study and three previously published cross-sectional studies on this topic in adult ***: Individuals with anemia had greater odds of having insomnia (adjusted odds ratio [OR]: 1.32;95% confidence interval [CI]: 1.03-1.70) compared with individuals without anemia. A significant association persisted after we excluded individuals with chronic inflammation, as suggested by C-reactive protein levels >1 mg/L (adjusted OR: 1.68;95% CI: 1.22-2.32). The meta-analysis results, including 22,134 participants, also identified a positive association between anemia and insomnia (pooled OR: 1.39;95% CI: 1.22-1.57).Conclusions: The presence of anemia was significantly associated with a higher likelihood of having insomnia in adults. Due to the nature of the cross-sectional study design, results should be interpreted with caution.
