Role of Socioeconomic Status in Hypertension among Chinese Middle-Aged and Elderly Individuals.

ABSTRACT: Hypertension is an important global health concern. The relationship between hypertension and socioeconomic status (SES) has been extensively studied. However, the role of SES in hypertension is still controversial, and this kind of study is sorely lacking among Chinese middle-aged and elderly individuals. The data of this study come from the China Health and Retirement Longitudinal Survey (CHARLS) released in May 2017. A total of 21,126 people from all around China, with ages older than 45 years, were enrolled in the questionnaire survey. Hypertension was determined according to the entry in CHARLS ("Do you have doctor-diagnosed hypertension?"), and 17,676 people responded to this entry. The basic demographic and SES information were collected. Multivariate logistic regression was used to evaluate the risk factors of hypertension. Concentration index was used to measure inequality of hypertension incidence. Among the investigated middle-aged and elderly individuals, 5,177/17,676 (29.3%) had doctor-diagnosed hypertension. Multivariate logistic regression implied that individuals older than 55 years (OR 1.436, 95% CI 1.085-1.900 for age interval of 55-64 years; OR 2.032, 95% CI 1.455-2.839 for age interval of 65-74 years; OR 1.672, 95% CI 1.031-2.714 for age interval of older than 75 years), male (OR 0.038, 95% CI 0.595-0.986), overweight (OR 2.47, 95% CI 1.462-4.183), and diabetes (OR 3.159, 95% CI 2.129-4.687) were associated with hypertension. For society support, individuals in the lowest quintile were more likely to suffer hypertension. Concentration index results suggested that different income groups did not show inequality on hypertension incidence. Elder age, male, overweight, diabetes, and poor society support were suggested to be associated with hypertension incidence among middle-aged and elderly individuals in China. Our study provides implications for controlling and managing hypertension.

Project description:BackgroundThere is growing evidence that the internet has beneficial effects on the mental health of middle-aged and older people (≥45 years), but the evidence is inconclusive, and the underlying mechanisms are less known.ObjectiveThis study aims to explore the relationship between multidimensional (devices, frequency, and purpose) internet use and depression in middle-aged and elderly Chinese, as well as the mediating effect of social participation. Moreover, this study will explore the moderating effect of the regional informatization development level (RIDL) on the relationships between individual internet use, social participation, and depression.MethodsData on 17,676 participants aged 45 years or older were obtained from the China Health and Retirement Longitudinal Study (CHARLS) 2018 data set. The 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10) was used to identify the presence of depression. Logistic regression was used to explore the relationship between each dimension of internet use and depression. Multiple linear regression was used to explore the mediating effect of social participation and the moderating effect of the RIDL.ResultsThe results showed that 28.33% (5008/17,676) of the total population had depression. In terms of regional subgroups, respondents living in the western region exhibited the highest proportion of depression (2041/5884, 34.69%). Internet use was negatively associated with depression (odds ratio 0.613, 95% CI 0.542-0.692; P<.001). Various dimensions of internet use positively contributed to individual social participation and reduced individual depression (devices: β=-.170, 95% CI -0.209 to -0.127; frequency: β=-.065, 95% CI -0.081 to -0.047; and purpose: β=-.043, 95% CI -0.053 to -0.031). In addition, the RIDL weakened the relationship between individual-level internet use and social participation (internet use: F74.12,9.82=7.55, P<.001; devices: F51.65/9.88=5.23, P=.005; frequency: F66.74/10.08=6.62, P=.001; and purpose: F66.52/9.78=6.80, P=.001), and negatively moderated the relationship between the frequency of internet use and depression (frequency: F662.67/188.79=3.51, P=.03).ConclusionsThis study found that different dimensions of internet use are associated with lower levels of depression. Social participation partially mediates the association between multidimensional internet use and depression in the eastern, central, and western regions, respectively. Additionally, the RIDL helps individuals further their internet use and social participation, reducing the impact of depression. However, this effect weakens sequentially from the western region to the central region and then to the eastern region.

Project description:OBJECTIVES:To explore whether bone mineral density (BMD) is associated with arterial stiffness in middle-aged and elderly people with an advanced arterial stiffness index as indicated by the cardio-ankle vascular index (CAVI). DESIGN:A cross-sectional study. SETTING:This study was conducted from September 2015 to May 2017 at the geriatrics department of a provincial medical centre in China. PARTICIPANTS:A total of 580 patients aged 50 and over were enrolled in the study. The mean age of the group was 64.82±11.4 years, and 63.1% were male. PRIMARY OUTCOME MEASURES:Associations of age with CAVI values and BMD. Associations between BMD and CAVI values. RESULTS:With increasing age, CAVI values gradually increased (p<0.001) and the femoral neck (FN) and total hip (TH) BMD gradually decreased (p<0.001, all). In the bivariate correlation analyses between the covariates and CAVI values, age and CAVI values showed the greatest positive correlation (r=0.631, p<0.001), and CAVI values were negatively correlated with FN BMD (r=-0.229, p<0.001) and TH BMD (r=-0.218, p<0.001). In the linear regression analyses, TH BMD (B=-1.812 (95% CI -2.475 to -1.149), p<0.001) and FN BMD (B=-1.968 (95% CI -2.651 to -1.284), p<0.001) were negatively correlated with CAVI values. After adjusting for age, gender, body mass index, smoking, history of cardiovascular or cerebrovascular disease, history of diabetes mellitus, systolic blood pressure, high-density lipoprotein cholesterol, blood uric acid, fibrinogen and estimated glomerular filtration rate, only TH BMD was still negatively correlated with CAVI values (B=-0.843 (95%CI -1.454 to -0.232), p=0.007). However, there was no consistent and significant correlation between lumbar spine BMD and CAVI values. CONCLUSION:In this cross-sectional study, a significant correlation between TH BMD and CAVI values was observed in middle-aged and elderly Chinese inpatients. However, our cohort was a small sample of inpatients, and prospective studies from more centres are expected.
