ABSTRACT

Objective@#Evidence regarding alcohol consumption and cognitive impairment is controversial. Whether cessation of drinking alcohol by non-dependent drinkers alters the risk of cognitive impairment remains unknown. This study prospectively evaluated the potential association between the history of lifetime alcohol cessation and risk of cognitive impairment.@*Methods@#This study included 15,758 participants age 65 years or older, selected from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) that covered 23 provinces in China. Current alcohol use status, duration of alcohol cessation, and alcohol consumption before abstinence were self-reported by participants; cognitive function was evaluated using Mini-mental State Examination (MMSE). Cause-specific hazard models and restricted cubic splines were applied to estimate the effect of alcohol use on cognitive impairment.@*Results@#Among the 15,758 participants, mean (± SD) age was 82.8 years (± 11.9 years), and 7,199 (45.7%) were males. During a mean of 3.9 years of follow-up, 3,404 cases were identified as cognitive impairment. Compared with current drinkers, alcohol cessation of five to nine years [adjusted @*Conclusion@#A longer duration of alcohol cessation was associated with a lower risk of cognitive impairment assessed by MMSE. Alcohol cessation is never late for older adults to prevent cognitive impairment.

ABSTRACT

Objective@#This study aims to investigate the correlation of an ultrasonic scoring system with intraoperative blood loss (IBL) in placenta accreta spectrum (PAS) disorders.@*Methods@#A retrospective cohort study was conducted between January 2015 and November 2019. Clinical data for patients with PAS have been obtained from medical records. Generalized additive models were used to explore the nonlinear relationships between ultrasonic scores and IBL. Logistic regressions were used to determine the differences in the risk of IBL ≥ 1,500 mL among groups with different ultrasonic scores.@*Results@#A total of 332 patients participated in the analysis. Generalized additive models showed a significant positive correlation between score and blood loss. The amount of IBL was increased due to the rise in the ultrasonic score. All cases were divided into three groups according to the scores (low score group: ≤ 6 points, @*Conclusions@#The risk of blood loss equal to or greater than 1,500 mL increases further when ultrasonic score greater than or equal to 10 points, the preparation for transfusion and referral mechanism should be considered.

ABSTRACT

To investigate the relationship of sleep duration and sleep quality with anxiety in the elderly aged 60 years and older in China. The elderly aged 60 years and older were selected from the China Short-term Health Effects of Air Pollution Study conducted between July 18, 2017 and February 7, 2018. Multivariate logistic regression models were used to analyze the association of sleep duration and sleep quality with anxiety. A total of 3 897 elderly aged 60 years and older were included in the study. The age of the elderly was (73.4±8.0) years old. Among the elderly surveyed, 6.5 were defined with anxiety, and 18.7 reported poor sleep quality. Multivariate logistic regression models showed shorter sleep duration was the risk factor for anxiety in the elderly that after adjusting for factors such as general demographics, socioeconomic factors, lifestyle, health status, social support and ambient fine particulates exposure. Compared with the elderly with 7 hours of sleep duration daily, the (95) of anxiety for those with sleep duration ≤ 6 hours was 2.09 (1.49-2.93). Compared with those with good sleep quality, the (95) of anxiety for those with poor sleep quality was 5.12 (3.88-6.77). We also found statistically significant correlations of the scores of subscales of Pittsburgh sleep quality index with anxiety, in which the effects of sleep disturbance, subjective sleep quality and daytime dysfunction scores were most obvious, the (95) were 4.63 (3.55-6.04), 2.75 (2.33-3.23) and 2.50 (2.19-2.86), respectively. Subgroup analysis showed that the association of sleep duration and sleep quality with anxiety was more obvious in males and in those aged <80 years. Shorter sleep duration and poor sleep quality are associated with anxiety in the elderly in China.

ABSTRACT

To analyze influencing factors for depressive symptoms in the elderly aged 65 years and older in 8 longevity areas in China. We recruited 2 180 participants aged 65 years and older in 8 longevity areas from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey in 2017. Multivariate logistic regression analysis was performed to evaluate the relationships of socio-demographic characteristics, behavioral lifestyle, chronic disease prevalence, functional status, family and social support with depressive symptoms in the elderly. The detection rate of depression symptoms was 15.0 in the elderly aged 65 years and older in 8 longevity areas of China, and the detection rate of depression symptoms was 11.5 in men and 18.5 in women. Multivariate logistic regression analysis results showed that the detection rate of depressive symptoms was lower in the elderly who had regular physical exercises (=0.44, 95: 0.26-0.74), frequent fish intakes (=0.57, 95: 0.39-0.83), recreational activities (=0.65, 95: 0.44-0.96), social activities (=0.28, 95: 0.11-0.73) and community services (=0.68, 95: 0.50-0.93). The elderly who were lack of sleep (=2.04, 95: 1.49-2.80), had visual impairment (=1.54, 95: 1.08-2.18), had gastrointestinal ulcer (=2.97, 95: 1.53-5.77), had arthritis (=2.63, 95: 1.61-4.32), had higher family expenditure than income (=1.80, 95: 1.17-2.78) and were in poor economic condition (=4.58, 95: 2.48-8.47) had higher detection rate of depressive symptoms. The status of doing physical exercise, fish intake in diet, social activity participation, sleep quality or vision, and the prevalence of gastrointestinal ulcers and arthritis were associated with the detection rate of depressive symptoms in the elderly.

ABSTRACT

To understand the current status of BMI of the elderly and related factors in longevity areas in China, and provide scientific evidence for the control of BMI level in elderly population. Data used in this study were obtained from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey. A total of 2 825 elderly in 8 longevity areas in China were surveyed and measured in 2017. The BMI levels of 2 217 elderly aged 65 years and older were calculated and in follow up. The ordered classification logistic regression model was used to analyze the influencd factors for the BMI in the elderly. The BMI of the elderly in 8 longevity areas in China was (22.36±3.87) kg/m(2), and it was (22.76±3.58) kg/m(2) for males and (21.75±3.98) kg/m(2) for females. The BMI levels were normal in 1 165 elderly persons. The prevalence of underweight, overweight and obesity were 15.8, 24.0 and 7.7, respectively. Multivariate analysis showed that the main factors affecting the BMI of people under 100- years old were age (65-: =2.78, 95: 1.87-4.15; 80-: =1.47, 95: 1.00-2.17), smoking status (=0.46, 95: 0.32-0.66), annual household income (<30 000 Yuan: =1.26, 95: 1.07-1.47; 30 000-70 000 Yuan: =1.52, 95: 1.12-1.86), and frequency of tea intake(=1.36, 95: 1.01-1.71), while the factor in people aged ≥100 years was gender (=3.68, 95: 1.32-10.36). The prevalence of underweight, overweight and obesity were high in the elderly from longevity areas in China. It is necessary to pay attention to the trend of overweight and obesity due to smoking, higher annual household income and regular tea drinking in the elderly men.

ABSTRACT

To understand the relationship between visual impairment and risk of all-cause mortality in the elderly aged 65 years and older in 8 longevity areas in China. The data of the elderly aged 65 years and older in the project in 2012 were obtained from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey, including physical measurement and survival status, and a follow-up for survival outcomes were conducted in 2014 and 2017 respectively. Cox proportional hazard regression model was used to analyze the influence of visual impairment on mortality. Gender and age specific analysis was conducted. A total of 1 736 elderly adults were included. A total of 943 deaths occurred during the 5-year follow-up period with a 5-year mortality rate of 54.3. The 5-year mortality rate was 76.7 in the group with visual impairment, and 47.6 in the group without visual impairment (<0.001). After adjusting for demographic information, life style and some disease factors, the risk of 5-year mortality in the group with visual impairment group was 1.30 times higher than that in the group without visual impairment (=1.30, 95: 1.09-1.55). In the females, the risk for mortality in the group with visual impairment was 1.48 times higher than that in the group without visual impairment (=1.48, 95:1.20-1.84). However, vision status was not associated with the risk for mortality in males (=1.02, 95: 0.72-1.43). The risk for mortality in the group with visual impairment was 1.39 times higher than that in the group without visual impairment in the elderly aged over 90 years (=1.39, 95: 1.13-1.70). Vision status was not associated with mortality risk in the elderly aged 65-79 years and 80-89 years (=1.37, 95: 0.61-3.07; =0.95, 95: 0.61-1.48). In the elderly people in China, visual impairment is a risk factor for mortality.

ABSTRACT

To investigate the association between estimated glomerular filtration rate (eGFR) and all-cause mortality in the elderly aged 65 years and older in longevity areas in China. Data used in this study were obtained from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey, 1 802 elderly adults were collected in the study during 2012-2017/2018. In this study, the elderly were classified into 4 groups, moderate-to-severe group [<45 ml·min(-1)·(1.73 m(2))(-1)], mild-to-moderate group [45- ml·min(-1)·(1.73 m(2))(-1)], mild group [60- ml·min(-1)·(1.73 m(2))(-1)] and normal group [≥90 ml·min(-1)·(1.73 m(2))(-1)] according to their eGFR levels. After 6 years of follow-up, 852 participants died, with a mortality rate of 47.3. Multivariate Cox regression analysis showed that the levels of eGFR were negatively correlated with all-cause mortality risk in the elderly (the of elderly was 0.993 and the 95 was 0.989-0.997 for every unit of eGFR increased, =0.001), while compared with the group with normal eGFR, the (95) of the elderly in the moderate-to-severe group, mild-to-moderate group, and mild group were 1.690 (1.224-2.332, =0.001), 1.312 (0.978-1.758, =0.070), 1.349 (1.047-1.737, =0.020) respectively [trend test <0.001]. The decrease in eGFR was associated with higher mortality risk among the elderly in longevity areas in China.

ABSTRACT

To establish a prediction model for 6-year incidence risk of chronic kidney disease (CKD) in the elderly aged 65 years and older in China. In this prospective cohort study, we used the data of 3 742 participants collected during 2008/2009-2014 and during 2012-2017/2018 from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey. Two follow up surveys for renal function were successfully conducted for 1 055 participants without CKD in baseline survey. Lasso method was used for the selection of risk factors. The risk prediction model of CKD was established by using Cox proportional hazards regression models and visualized through nomogram tool. Bootstrap method (1 000 resample) was used for internal validation, and the performance of the model was assessed by C-index and calibration curve. The mean age of participants was (80.8±11.4) years. In 4 797 person years of follow up, CKD was found in 262 participants (24.8). Age, BMI, sex, education level, marital status, having retirement pension or insurance, hypertension prevalence, blood uric acid, blood urea nitrogen and total cholesterol levels and estimated glomerular filtration rate in baseline survey were used in the model to predict the 6-year incidence risk of CKD in the elderly. The corrected C-index was 0.766, the calibration curve showed good consistence between predicted probability and observed probability in high risk group, but relatively poor consistence in low risk group. The incidence risk prediction model of CKD established in this study has a good performance, and the nomogram can be used as visualization tool to predict the 6-year risk of CKD in the elderly aged 65 years and older in China.

ABSTRACT

Objective To investigate the effect of ginkgo diterpene lactones on hypoxia-induced apoptosis and angiogenesis of human umbilical vein endothelial cells (HUVECs) and the related molecular mechanisms. Methods HUVECs were cultured under hypoxia for 24 h, and then treated with ginkgo diterpene lactones (low-dose: 6.25 mg/L and high-dose: 25.00 mg/L). MTT assay was used to detect the cell activity. Flow cytometry was used to detect the apoptosis of HUVECs. Transwell assay was employed to detect the migration of HUVECs. Quantitative real-time polymerase chain reaction and Western blotting were used to test the expression levels of mRNA and protein of hypoxia-inducible factor 1α (HIF-1α), apoptosis-related genes (B-cell lymphoma 2[Bcl-2]and B-cell lymphoma 2-related X protein[Bax]), and angiogenesis-related genes (vascular endothelial growth factor[VEGF]and transforming growth factor β[TGF-β]). Results Compared with the normal group, the HUVEC activity was significantly decreased after exposed to hypoxia for 24 h (P<0.05), and the apoptosis rate of HUVECs and mRNA and protein expression levels of HIF-1α were significantly higher (all P<0.05). The cell activity and migration ability of HUVECs were significantly higher in the low- and high-dose ginkgo diterpene lactones groups than those in the hypoxia group (all P<0.05), and the apoptosis rates of HUVECs were significantly lower than those in the hypoxia group (both P<0.05). Meanwhile, the cell activity and migration ability were significantly higher in the high-dose group than those in the low-dose group (both P<0.05), and the apoptosis rate was significantly lower than that in the low-dose group (P<0.05). The mRNA and protein expression levels of HIF-1α and Bax were lower in the low- and high-dose ginkgo diterpene lactones groups than those in the hypoxia group, and the mRNA and protein expression levels of Bcl-2, VEGF and TGF-β were higher than those in the hypoxia group; and the expression changes of the above genes were more significant in the high-dose group. Conclusion Ginkgo diterpene lactones can improve hypoxia-induced apoptosis and angiogenesis of HUVECs by regulating the expression levels of HIF-1α and apoptosis- and angiogenesis-related genes, and it might be used as a new agent to treat anoxic vascular diseases.

ABSTRACT

<p><b>Background</b>Cesarean section (CS) is an independent risk factor for placenta accreta. Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa.</p><p><b>Methods:</b>A retrospective, single-center, case-control study was conducted at Peking University Third Hospital. Relevant clinical data of singleton pregnancies between January 2010 and September 2017 were recorded. The case group included women with placenta accreta who had placenta previa and one previous CS. Control group included women with one previous CS that was complicated with placenta previa. Maternal age, body mass index, gestational age, fetal birth weight, gravity, parity, induced abortion, the rate of women received assisted reproductive technology, other uterine surgery, and primary elective CS were analyzed between the two groups.</p><p><b>Results:</b>The rate of primary elective CS (90.1% vs. 69.9%, P < 0.001) was higher, and maternal age was younger (32.7 ± 4.7 years vs. 34.6 ± 4.0 years, P < 0.001) in case group, compared with control group. Case group also had higher gravity and induced abortions compared with the control group (both P < 0.05). Primary CS without labor was associated with significantly increased risk of placenta accreta in a subsequent pregnancy complicated with placenta previa (odds ratio: 3.32; 95% confidential interval: 1.68-6.58).</p><p><b>Conclusion:</b>Women with a primary elective CS without labor have a higher chance of developing an accreta in a subsequent pregnancy that is complicated with placenta previa.</p>

ABSTRACT

<p><b>OBJECTIVE</b>This study aims to assess the status of successful aging (SA) in longevity areas in China and explore multiple factors associated with SA among the young-old and oldest-old.</p><p><b>METHODS</b>A total of 2296 elderly people aged 65 and older were interviewed in the longevity areas sub-sample of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2012. Baseline assessments included a researcher-administered questionnaire, physical examination, and laboratory testing. A logistic regression model was used to identify factors associated with SA.</p><p><b>RESULTS</b>The prevalence of SA was 38.81% in the CLHLS in 2012. There were significant differences between ages groups, with SA compromising 56.85% among ⋝65 years group and 20.31% among ⋝100 years group (χ2trend=126.73, P<0.01). The prevalence of SA among females was 33.59%, which was significantly lower than that among males (45.58%) (χ2gender=33.65, P<0.05). In the regression analysis, having anemia (OR=0.744, 95% CI: 0.609-0.910), poor lifestyle (OR=0.697, 95% CI: 0.568-0.854), poor sleep quality (OR=0.558, 95% CI: 0.456-0.682), and central obesity (OR=0.684, 95% CI: 0.556-0.841) were the main factors associated with SA. The promoting SA rate decreased as age increased, and the group of 65-79 years had higher odds than the other age group.</p><p><b>CONCLUSION</b>Preventing central obesity, improving sleep quality and promoting healthy lifestyle may contribute to achieve SA among the elderly.</p>

ABSTRACT

<p><b>BACKGROUND</b>Prevalence of atrial fibrillation (AF) is increasing as the world ages. AF is associated with higher risk of mortality and disease, including stroke, hypertension, heart failure, and dementia. Prevalence of AF differs with each population studied, and research on non-Western populations and the oldest old is scarce.</p><p><b>METHODS</b>We used data from the 2012 wave of the Chinese Longitudinal Healthy Longevity Survey, a community-based study in eight longevity areas in China, to estimate AF prevalence in an elderly Chinese population (n = 1418, mean age = 85.6 years) and to identify risk factors. We determined the presence of AF in our participants using single-lead electrocardiograms. The weighted prevalence of AF was estimated in subjects stratified according to age groups (65-74, 75-84, 85-94, 95 years and above) and gender. We used logistic regressions to determine the potential risk factors of AF.</p><p><b>RESULTS</b>The overall prevalence of AF was 3.5%; 2.4% of men and 4.5% of women had AF (P < 0.05). AF was associated with weight extremes of being underweight or overweight/obese. Finally, advanced age (85-94 years), history of stroke or heart disease, low high-density lipoprotein levels, low triglyceride levels, and lack of regular physical activity were associated with AF.</p><p><b>CONCLUSIONS</b>In urban elderly, AF prevalence increased with age (P < 0.05), and in rural elderly, women had higher AF prevalence (P < 0.05). Further exploration of population-specific risk factors is needed to address the AF epidemic.</p>

ABSTRACT

This study was aimed to evaluate the agreement between the self-reported sodium intake level and 24-h urine sodium excretion level in Chinese. The 24-h urine collection was conducted among 2112 adults aged 18-69 years randomly selected in Shandong Province, China. The subjects were asked whether their sodium intake was low, moderate, or high. The weighted kappa statistics was calculated to assess the agreement between 24-h urine sodium excretion level and self-reported sodium intake level. One third of the subjects reported low sodium intake level. About 70% of the subjects had mean 24-h sodium excretion>9 g/d, but reported low or moderate sodium intake. The agreement between self-reported sodium intake level and 24-h urine sodium excretion level was low in both normotensive subjects and hypertensive subjects. These findings suggested that many subjects who reported low sodium intake had actual urine sodium excretion>9 g/d. Sodium intake is often underestimated in both hypertensive and normotensive participants in China.

ABSTRACT

<p><b>OBJECTIVE</b>To estimate the prevalence of elevated blood pressure (EBP) in Chinese children and identify individual and family factors associated with EBP.</p><p><b>METHODS</b>A nationwide cross-sectional study was conducted in 2010 using stratified cluster sampling. Participants' blood pressure was measured, and their parents completed a questionnaire on personal and family characteristics. Prevalence and correlates of EBP were assessed.</p><p><b>RESULTS</b>Among a total of 24,333 participants, 20.2% of boys and 16.3% of girls had EBP. The prevalence of EBP increased with the ascending trend of waist circumference, Waist-to-height ratio, and body mass index. The adjusted prevalence ratios (aPRs) for obese boys and girls were 2.50 and 2.97, respectively. Fewer urban boys (16.2%) had EBP than rural boys (21.7%). Boys with a family history of hypertension were 12% more likely to have EBP. Children whose mothers received a college education tended to have lower likelihood of EBP; with an aPR was 0.85 among boys and 0.78 among girls.</p><p><b>CONCLUSION</b>EBP is common among obese students and those who have a family history of hypertension. A negative association between mothers' education levels and EBP risk in children was found.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the relationship between socioeconomic status (SES) and overweight and obesity among elementary school children.</p><p><b>METHODS</b>This cross-sectional study was conducted from September to November, 2010. A stratified random cluster sampling was used from sampling frame of eight provinces by the geographical and economic development distributions in mainland China. A total of 19 934 students aged 7-12 years old participated in this study. All subjects were evaluated the status of overweight and obesity. Green's scoring SES was used to evaluate the SES of the participants. Multivariate logistic regression analysis was performed to examine the relationship between SES and overweight and obesity among children.</p><p><b>RESULTS</b>According to the scores of Green's SES, the participants' SES were divided into three levels, the prevalence of overweight were 7.4% (538/7295), 9.3% (560/6013) and 12.6% (832/6626), and the prevalence of obesity were 4.4% (321/7295) , 6.4% (387/6013) and 10.2% (677/6626) from low to high SES level, respectively (χ(2) value were 133.82, 180.27, respectively, P < 0.01). After adjusted by age, urban and rural and economic regions, compared with the participants with low SES, the OR (95%CI) of having overweight and obesity among participants with high SES were 1.83(1.61-2.08) for boys and 1.67(1.42-2.00) for girls; the OR (95%CI) with middle SES were 1.30(1.15-1.48) for boys and 1.23(1.04-1.46) for girls.</p><p><b>CONCLUSION</b>The prevalence of overweight and obesity rises with the family's SES levels. There was a positive correlation between SES and overweight and obesity among school-aged children.</p>

ABSTRACT

Objective To study the efficacy of ‘China Healthy Lifestyle for All' (CHLA).Methods Under similar GDP status,two counties (one with CHLA and one without) were randomly selected from each province of China.Cluster randomized sampling method was performed to select 500 over 18-year-olds from each county.Face-to-face questionnaire interview was used to collect data related to knowledge,awareness and behavior on healthy lifestyle.Generalized Estimated Equation was fitted for the multi-factor analysis.Results A total of 31 396 subjects were surveyed,with 11 871 urban and 6312 rural residents from counties that had under gone the CHLA.Another 3934 urban and 9279 rural subjects were from those counties that had not carried out the CHLA (as control group).In both urban and rural areas,the CHLA group seemed more likely to be aware of the Campaign itself and the knowledge on healthy lifestyle,than the control group as well as consciously limiting the salt and oil intake,after adjusting other factors such as county,gender,age and education.In the urban area,rates of awareness on the Campaign in both the CHLA and control groups were 57.1% and 31.7% (OR=3.33,95%CI:1.63-6.80,P=0.001) respectively.And in the rural area,the rates of consciously limiting the salt intake in the CHLA group and in the control group were 51.5% and 38.8% (OR=l.70,95%CI:1.13-2.56,P=0.011) respectively.In the urban area,subjects from the CHLA group were more likely to use the healthy supportive tools than the control group.Rates of using salt measuring spoons in both the CHLA group and control groups were 49.2% and 29.5% (OR=2.46,95% CI:1.45-4.17,P=0.001) respectively.In the rural area,statistically significant difference was only found in the rate of using scaled oil pots (OR=2.11,95%CI:1.09-4.09,P=0.028) between the CHLA group and the control group.In the rural area,the CHLA group was more likely to engage in more physical activities than the control group.No differences on the rates related to physical activities were found in the urban area.Some behavioral indicators such as the rates of consciously maintaining the body weight,daily intake of vegetables and fruits showed no statistically significant differences between the CHLA group and the control group either in the urban or in the rural areas.Conclusion The ‘China Healthy Lifestyle for All' seemed to have improved the knowledge on awareness and conciousness of healthy lifestyle.However,the effect of CHLA on the healthy behavior needs to be further evaluated.
