- ObjectivesTo examine the association between tea consumption and depressive symptoms in Chinese older people and to explore the mediating role of cerebrovascular disease in the association. DesignPopulation-based cross-sectional study. SettingA rural community near Qufu in Shandong, China. ParticipantsCommunity-dwelling individuals aged 60 and older (mean 68.6; 59.3% female) from the Confucius Hometown Aging Project (N=1,368). MeasurmentsData were collected through interviews, clinical examinations, and psychological testing, following a standard procedure. Presence of high depressive symptoms was defined as a score of 5 or greater on the 15-item Geriatric Depression Scale. ResultsOf the 1,368 participants, 165 (12.1%) were weekly and 489 (35.7%) were daily tea consumers. Compared with no or irregular tea consumption, controlling for age, sex, education, leisure activities, number of comorbidities, and Mini-Mental State Examination score, the odds ratios of having high depressive symptoms were 0.86 (95% confidence interval (CI)=0.56-1.32) for weekly and 0.59 (95% CI=0.43-0.81) for daily tea consumption (P for linear trend=.001); the linear trend of the association remained statistically significant when further controlling for history of stroke, transient ischemic attacks, and presence of carotid plaques. ConclusionsDaily tea consumption is associated with a lower likelihood of depressive symptoms in Chinese older people living in a rural community. The association appears to be independent of cerebrovascular disease and atherosclerosis.

- The potential mediating effect of cardiovascular diseases (CVDs) (e.g., ischemic heart disease and stroke) on the association between abnormal serum lipids and late-life depressive symptoms has not been investigated. We aimed to examine the associations between serum lipids and elevated depressive symptoms among older Chinese people and to determine the extent to which CVDs mediate their associations. This cross-sectional study included 1,529 participants (age a parts per thousand yen60 years, 59.2 % women) in the Confucius Hometown Aging Project. In June 2010-July 2011, data were collected through an interview, clinical examinations, and laboratory tests. Abnormal serum lipids were defined according to international criteria and use of hypolipidemic drugs. Presence of elevated depressive symptoms was defined as the 15-item Geriatric Depression Scale score a parts per thousand yen5. Data were analyzed with logistic and mediation models controlling for potential confounders. The prevalence of depressive symptoms was 20.3 %. Depressive symptomatology was significantly associated with high total cholesterol, high triglycerides, low high-density lipoprotein cholesterol (HDL-C), high low-density lipoprotein cholesterol (LDL-C), and dyslipidemia (p < 0.05). The mediating effects on the associations of serum lipids with depressive symptoms were statistically significant for ischemic heart disease and stroke with the proportion of mediating effects over the total effects ranging 4.7-7.0 % and 7.3-12.1 %, respectively. Elevated depressive symptoms are associated with lipid profile characterized by high cholesterol, high triglycerides, low HDL-C, high LDL-C, and dyslipidemia; the associations are partially mediated by ischemic heart disease and stroke. These findings imply that unfavorable lipid profile may be involved in late-life depressive symptoms independent of atherosclerotic disorders.

- Objectives: Epidemiological data concerning atherosclerotic disease among older people in rural China are sparse. We seek to determine prevalence and cardiovascular risk factor profiles for peripheral artery disease (PAD) and carotid atherosclerosis (CAS) among Chinese older people living in a rural community. Methods: This cross-sectional study included 1499 participants (age >= 60 years, 59.0% women) of the Confucius Hometown Aging Project in Shandong, China. From June 2010-July 2011, data were collected through interviews, clinical examinations, and laboratory tests. PAD was defined as an ankle-brachial index <= 0.9. Carotid intima-media thickness (cIMT) and carotid artery stenosis were assessed by ultrasonography. We defined moderate stenosis as carotid stenosis >= 50%, and severe stenosis as carotid stenosis >= 70%. cIMT >= 1.81 mm was considered as an increased cIMT (a measure of CAS). Data were analyzed with multiple logistic models. Results: The prevalence was 5.7% for PAD, 8.9% for moderate stenosis, 1.8% for severe stenosis, and 11.2% for increased cIMT. After controlling for multiple potential confounders, diabetes, an increased low-density lipoprotein cholesterol (LDL-C)/high-density lipoprotein cholesterol (HDL-C) ratio, and hypertension were significantly or marginally associated with PAD. Ever smoking, hypertension, and an increased LDL-C/HDL-C ratio were significantly associated with an increased likelihood of increased cIMT. An increasing number of those cardiovascular risk factors were significantly associated with an increasing odds ratio of PAD and increased cIMT, respectively (p for linear trend < 0.001). Conclusion: Among Chinese older people living in a rural community, PAD, carotid artery stenosis, and an increased cIMT are relatively uncommon. Cardiovascular risk factor profiles for PAD and CAS are slightly different, with hypertension and an increased LDL-C/HDL-C ratio being associated with an increased likelihood of both PAD and increased cIMT.

- Aim: To investigate the associations between medication use and functional dependence in Chinese older people living in a rural community. Methods: The cross-sectional study included 1538 participants (age >= 60 years, 59.1% women) in the Confucius Hometown Aging Project in Shandong, China. In June 2010 to July 2011, data on demographics, lifestyle factors, health history, basic activities of daily living (ADL), instrumental ADL, and use of medications were collected through interviews and clinical examinations. Functional status was categorized into no dependence, dependence only in instrumental ADL and dependence in basic ADL. Data were analyzed with multinomial logistic models controlling for potential confounders. Results: Dependence in instrumental or basic ADL was significantly associated with use of antihypertensives and hypolipidemic agents, and basic ADL dependence was also associated with use of sedatives or tranquilizers and cardiac glycosides. An increased number of concurrently used medications was significantly associated with an increased likelihood of dependence in basic ADL (P for trend = 0.016). Compared with non-users of any medication, individuals who concurrently used three or more classes of medications had a multi-adjusted odds ratio of 2.91 (95% confidence interval 1.02-8.28) for dependence in basic ADL. Conclusions: Use of antihypertensives, hypolipidemic drugs, cardiac glycosides and sedatives or tranquilizers, especially use of multiple classes of medications, is correlated with functional dependence among older people in rural China.

- Background The epidemiological scenario of cardiovascular risk factors (CRFs) among elderly people in rural China is unclear. We seek to describe the distribution, burden and management of major CRFs among older Chinese people living in the rural community. Methods This cross-sectional study included 1538 participants in the Confucius Hometown Aging Project (2010-2011) of people 60 years of age (mean age 68.6 years; 59.1% women) who lived in a rural community nearby Qufu, Shandong, China. Data were collected through a face-to-face interview, a clinical examination and laboratory tests. We carried out descriptive analysis on the prevalence and management of major CRFs. Results The overall prevalence of current smoking, physical inactivity, hypertension, diabetes, high cholesterol and obesity were 13.8%, 83.7%, 76.0%, 26.6%, 42.4% and 13.1%, respectively: 82.8% and 50.4% of participants had 2 and 3, respectively, of the six CRFs. Prevalence of alcohol consumption was 18.7%. Men were more likely to smoke and consume alcohol than women, whereas women were more likely to be obese and physically inactive than men (p<0.001). Prevalence of physical inactivity and hypertension increased with age, prevalence of alcohol intake and obesity decreased with age, and prevalence of smoking and diabetes was stable. Hypertension, diabetes and high cholesterol were treated in 60.6%, 68.1% and 41.1% of those with the disease, respectively, but only 11.3%, 13.7% and 31.7% achieved good control. Conclusions CRFs are highly prevalent and poorly controlled among elderly people in rural China, where men and women have different CRF profiles. Intervention programs targeting major CRFs may improve the health of older people in China.

- Background The burden of chronic diseases in China is substantial now. Data on patterns of chronic diseases and multimorbidity among older adults, especially among those living in rural areas, are sparse. Objective We aim to investigate the prevalence and patterns of chronic disease pairs and multimorbidity in elderly people living in rural China. Methods This population-based study included 1480 adults aged 60 years and over (mean age 68.5 years, 59.4% women) living in a rural community. Data were derived from the Confucius Hometown Aging Project in Shandong, China (June 2010-July 2011). Chronic diseases were diagnosed through face-to-face interviews, clinical examinations, and laboratory tests. Patterns of chronic disease pairs and multimorbidity were explored using logistic regression and exploratory factor analyses. Results The prevalence of individual chronic diseases ranged from 3.0% for tumor to 76.4% for hypertension, and each disease was often accompanied with three or more other chronic diseases. The observed prevalence of pairs of chronic conditions exceeded the expected prevalence for several conditions, such as cardiovascular diseases and metabolic disorders, as well as pulmonary diseases and degenerative disorders. Chronic multimorbidity (>= 2 chronic diseases) affected more than 90% of subjects, and two patterns of chronic multimorbidity were identified: cardiopulmonary-mental-degenerative disorder pattern (overall prevalence, 58.2%), and cerebrovascular-metabolic disorder pattern (62.6%). Prevalence of the cardiopulmonary-mental-degenerative disorder pattern increased with age, and was higher in men than women; whereas prevalence of the cerebrovascular-metabolic disorder pattern was higher in women than in men but did not vary by age. Conclusion Chronic multimorbidity was highly prevalent among older Chinese adults living in rural areas, and there were specific patterns of the co-occurrence of chronic diseases. Effort is needed to identify possible preventative strategies based on the potential clustering of chronic diseases.

- Background: The relationship between the metabolic syndrome and subclinical atherosclerosis among elderly people remains controversial. We seek to investigate the associations of metabolic syndrome and its components with subclinical carotid atherosclerosis in older people living in rural China. Methods: This cross-sectional study included 911 participants (age >= 60 years, 59.4% women) of the community-based Confucius Hometown Aging Project in Shandong, China, who were free of clinical cardiovascular disease. In 2010-2011, data were collected through interviews, clinical examinations, and laboratory tests. Carotid intima media thickness (cIMT) and carotid artery plaque were assessed using ultrasonography. Metabolic syndrome was defined by four sets of criteria. Data were analyzed with multiple general linear and logistic regression models. Results: Carotid plaque was detected in 514 (56.4%) persons. Depending on the defining criteria, prevalence of metabolic syndrome ranged from 30.6% to 56.9%. Hypertension, elevated blood pressure (>= 130/85 mmHg), diabetes/prediabetes, and high fasting plasma glucose (>= 5.6 mmol/L) were significantly associated with an increased likelihood of carotid plaque, whereas an increased cIMT was associated with elevated blood pressure and hypertension (P < 0.05). Obesity, high triglycerides, and dyslipidemia were not associated with carotid artery plaque or cIMT. The significant association of metabolic syndrome with an increased likelihood of carotid plaque disappeared when elevated blood pressure and high plasma glucose were added to the models. Metabolic syndrome was not associated with cIMT. Conclusions: Metabolic syndrome is associated with subclinical carotid plaque among Chinese elderly people, driven primarily by elevated blood pressure and hyperglycemia. Older adults with metabolic syndrome, especially those with high blood pressure and hyperglycemia, may benefit from evaluation for subclinical atherosclerosis.

- Background: The interactive effect between diabetes and impaired kidney function on cognitive impairment in older adults has not yet been reported. The aim of this study was to investigate the association of diabetes and impaired kidney function with cognitive impairment among Chinese older people living in a rural area. Methods: This cross-sectional study included 1,358 participants (age >= 60 years; 60.5 % women) in the population-based Confucius Hometown Aging Project in Shandong, China. Data on demographics, lifestyle factors, health history, use of medications, global cognitive function, and kidney function were collected through structured interviews, clinical examinations, and blood tests. We defined diabetes as a fasting plasma glucose level >= 7.0 mmol/l or use of hypoglycemic agents, impaired kidney function as glomerular filtration rate estimated from cystatin C (eGFR(cys)) <60 ml/min/1.73 m(2). Cognitive impairment was defined using the education-based cut-off scores of Mini-Mental State Examination (MMSE). Data were analyzed using multiple general linear and logistic regression models. Results: Cognitive impairment was defined in 197 (14.5 %) persons. The multi-adjusted beta coefficient of MMSE score associated with diabetes was -0.06 (95 % confidence interval [CI], -0.16, 0.03); the corresponding figures associated with eGFR(cys) <60, 60-89.9, and >= 90 ml/min/1.73 m(2) were -0.15 (-0.28, -0.02), -0.01 (-0.10, 0.08), and 0 (reference) (P-trend = 0.046), respectively. Diabetes and impaired kidney function showed an interactive effect on cognitive impairment (P-interaction = 0.02). Compared with individuals having neither diabetes nor impaired kidney function, those with both conditions had a multi-adjusted odds ratio of 4.23 (95 % CI, 2.10-8.49) for cognitive impairment. The relative excess risk due to interaction was 2.74. Conclusions: This study suggests that concurrent presence of diabetes and impaired kidney function is associated with a substantial likelihood for cognitive impairment in older adults.
