Epidemiology and Risk Factors for Orthostatic Hypotension and Its Severity in Residents Aged > 60 years: A Cross-Sectional Study.

This cross-sectional study investigated the epidemiology and risk factors associated with orthostatic hypotension (OH) and its severity in older adults residing in the Jizhou community of Tianjin and the Jimei community of Xiamen. The study, conducted from March to September 2019, involved adults aged over 60. A comprehensive questionnaire survey was administered, resulting in the enrolment of 4383 older adults. The overall prevalence of OH was found to be 11.7% (516 out of 4383). Notably, a significant gender difference was observed, with a prevalence of 10% among males (194 out of 1926) and 13.1% among females (322 out of 2457) (P=0.002). Among individuals with OH, 332 exhibited mild symptoms, 64 had moderate OH, 58 had severe OH cases, and 50 have very severe OH. Multivariable logistic regression analysis revealed that being female, widowed, engaging in general social activities, and a history of hypertension, migraines, heart disease, cerebrovascular disease, and mental health conditions (anxiety and depression) were independently associated with OH. Ordinal logistic regression analysis further confirmed that hypertension, migraine, and a history of general anesthesia surgery were independently associated with the severity of OH. This study highlights a relatively high prevalence of OH among older adults in the Jizhou community of Tianjin and the Jimei community of Xiamen, China. The identified risk factors, particularly social activities, and hypertension, significantly influence the severity of OH. Further examination is required to corroborate these findings and investigate potential interventions.

Prevalence and risk factors of dementia in elder adults in Xiamen, China: A cross-sectional study.

BACKGROUND: The prevalence of dementia can vary by region and there is a cluster of more than 10 modifiable risk factors for dementia. Therefore, this study aimed to determine the prevalence of dementia in Xiamen, China, and identify independent risk factors associated with dementia. METHODS: This cluster sampling-based cross-sectional study enrolled elder adults from Xiamen City and conducted face-to-face interviews between April and August 2019. Data on the demographic characteristics and prevalence of dementia were collected. Multivariable logistic regression was used to analyse the factors associated with dementia. RESULTS: A total of 6430 subjects were enrolled. The prevalence of dementia was 7.62% (490/6430). A total of 490 patients were in the dementia group and 196 healthy matched subjects were selected for the control group with similar profiles for age, gender, and occupation as the dementia patients. Dementia patients were at increased risk for cerebrovascular disease, traumatic brain injury, and hypertension (all P < 0.05). Multivariable logistic regression analysis showed hypertension (odds ratio (OR) = 2.4, 95% confidence interval (CI): 1.62-3.63, P < 0.001) and traumatic brain injury (OR = 2.19, 95% CI: 1.16-4.53, P = 0.023) were independent risk factors for dementia. CONCLUSIONS: The prevalence of dementia was high among elder adults residing in Xiamen, China. Dementia patients were more likely to have hypertension and traumatic brain injury than the matched control group.

Levels of non-high-density-lipoprotein cholesterol are positively correlated with the risk of cognitive impairment in patients with intracerebral hemorrhage stroke.

BACKGROUND: Intracerebral hemorrhage (ICH) is one of the most common strokes, especially in developing countries. Recently, level of non-high-density lipoprotein cholesterol (non-HDL-C) has been implicated to be a better indicator for several lipid-related disorders. However, whether non-HDL-C can be used as an indicator for the risk of cognitive impairment in ICH patients remains to be elucidated. METHODS: In this study, we performed a retrospective study on patients with ICH treated at our institution to investigate the association between the level of non-HDL-C and various neuropsychological assessments, including mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA), activity of daily living scale (ADL), neuropsychiatric Inventory (NPI) and Hamilton depression rating scale 21 (HAMD21). RESULTS: We found that all scores of the tested assessments were significantly altered in ICH patients with a high non-HDL-C level. In addition, we revealed that non-HDL-C was negatively correlated with MMSE and MoCA scores and was positively correlated with ADL, NPI and HAMD21 scores. CONCLUSIONS: Our study suggests that non-HDL-C level can be used as a potential indicator for the risk of cognitive impairment in ICH patients.

Epidemiology of Frequent/Urgent Urination in Older Adults in China: A Multicenter, Cross-Sectional Study.

Background: Frequent/urgent urination is an event of multifactorial origin where involuntary leakage of urine occurs. Epidemiological study of this condition is of high importance due to its negative impact on the psychological, physical, and social well-being of the victims. Objective: This cross-sectional study aimed to investigate the prevalence of frequent/urgent urination in older adults in China. Method: In this study, a face-to-face questionnaire survey was conducted between April 2019 and August 2019 among 4,796 older adult populations in the communities of Tianjin jizhou and Xiamen jimei of China. Descriptive analysis, univariate regression, and all statistics were conducted in IBM SPSS v22. The count data were analyzed by chi-square test. P < 0.05 was considered statistically significant. Results: In the total investigated population, the prevalence of frequent or urgent urination was found in 1,164 patients (24.3%) where 31.7% (664/2,097) were male patients and 18.7% (500/2,699) were female patients, having a male-to-female ratio of 1.7:1. The prevalence was higher in the 70- to 84-year-old group (men: 33.3-34.8%, women 19.5-20.8%), whereas it was relatively low in the 65- to 69-year-old group and in older adults over 85 years of age (men 28.8, 30.3%, women 16.7, 18.5%, respectively). In terms of the course of the disease, among the population aged 65 years and above, 17.3% men and 9.9% women had frequent urination/urgency lasting for 1-4 years; 5-9 years in about 4.5% population (7.4% men and 4.2% women); 10-19 years in 4.9% men and 2.3% women; and more than 20 years duration in 1.6% men and 1.9% women. On the severity scale, mild frequent/urgent urination was observed in 24.6% of men and 15.4% women of Chinese older adults. Moderate cases were observed in 6.3% of men and 2.9% of women, whereas severe cases were found in 0.8% men and 0.2% women. Benign prostatic hyperplasia (BPH)/hypertrophy was the main risk factor for frequent/urgent urination in Chinese older adult men (P < 0.001). Obesity, hypertension, diabetes, heart disease, anxiety, depression, constipation, and brain injury were the other risk factors for frequent/urgent urination in Chinese older adult men and women. The results of this survey showed that smoking or drinking habits did not increase the prevalence of frequent/urgent urination in Chinese older adults. Conclusions: According to the results of this survey, the prevalence rate of frequent/urgent urination is high, and the course of the disease is long in Chinese older adults. BPH and depression, anxiety, and age-related chronic diseases increase the risk of frequent/urgent urination in Chinese older adults.
