Self-rated health and health-related quality of life among Chinese residents, China, 2010

Assessing health-related quality of life of Chinese population using CQ-11D

PURPOSE

This study aimed to assess the health-related quality of life (HRQoL) of the Chinese population by using the Chinese medicine quality of life-11 dimensions (CQ-11D) questionnaire and to identify factors associated with HRQoL.

METHODS

The data was derived from a survey conducted by the Institute of Pharmacoeconomics Evaluation at Beijing University of Chinese Medicine on the quality of life of the Chinese population. The sex and age of respondents were considered through quota sampling. Demographic, socioeconomic, and health indicators were collected using the structured questionnaire. We performed bivariate analyses first to examine the associations between the above factors and the HRQoL of respondents measured by the CQ-11D. Multivariate linear regression and ordinal logistic regression models were established to analyze the factors (demographic, socioeconomic, and health indicators) differences in HRQoL, as well as the risk of each group reporting problems across the 11 dimensions of CQ-11D.

RESULTS

From February 2021 to November 2022, a total of 7,604 respondents were involved and 7,498 respondents were included. The sample approximated the general adult Chinese population in terms of age, sex, and district of residence, and each geographic distribution ranged from 9.71 to 25.54%. Of the respondents, 45.84% were male, and 89.82% were Han ethnicity. The mean utility score ranged from 0.796 to 0.921 as age increased. According to the respondents, most health problems were identified in the PL (fatigue) (70.16%) and SM (quality of sleep) (63.63%) dimensions. The CQ-11D index scores varied with the demographic and socioeconomic characteristics of respondents, except for ethnicity (p > 0.05) and income (p > 0.05). The multivariate analysis revealed significant negative associations between health utility scores and various factors. These factors include sex (female), age over 65, belonging to ethnic minorities, rural household registration, being widowed or divorced, having a primary school education or below, being a student or unemployed, having a low income of 0-1,300, engaging in smoking or drinking, limited participation in physical activities, experiencing changes in self-perceived health status compared to the previous year, and having chronic diseases. The odds of respondents reporting problems in 11 dimensions varied among different socio-demographic groups.

CONCLUSIONS

This study reports the first Chinese population norms for the CQ-11D derived using a representative sample of the Chinese general population. Self-reported health status measured by the CQ-11D varies among different socio-economic groups. In addition to participation a physical activity and the presence of chronic disease, smoking and drinking also significantly influence HRQoL.

A Profile of Students Who Reported Mask Mandates Violate Civil Liberties during COVID-19

Objectives: In this paper, we explore differences in demographics, mask wearing attitudes and behaviors, and vaccination perceptions among students who reported that mask mandates violate their civil liberties compared to those who did not. Methods: Participants completed an online survey in April 2021 (N=619). Results: Students who reported that mask mandates violate their civil liberties were more likely to identify as male, report good health, attend in-person classes, and less likely to report being vaccinated (p<.05). These students were also more likely to endorse not wearing masks because masks make it difficult to breathe, provide a false sense of security, and because they value their independence; in addition, they were more likely to endorse not being vaccinated because they are at low perceived risk for infection, because of the unknown side effects of vaccines, and because vaccines were rushed into production (p<.05). Whereas students who reported that mask mandates violate their civil liberties were about 5.2 times more likely (p<.0001) to report being unvaccinated, vaccine status was only modestly positively correlated (r=.36, p<.0001). Conclusions: Although students who reported mask mandates violate their civil liberties were also more likely to be unvaccinated, these individuals are not necessarily the same, suggesting different public health messaging may be required to increase both mask use and vaccine uptake.

Population Norms for SF-6Dv2 and EQ-5D-5L in China

OBJECTIVES

To derive the population norms for EQ-5D-5L and SF-6Dv2 among the Chinese general population.

METHODS

Data collected alongside the Chinese SF-6Dv2 valuation study conducted between June and September 2019 were used. SF-6Dv2 and EQ-5D-5L, as well as social-demographic characteristics and self-reported chronic conditions, were collected through face-to-face interviews among a representative sample of the general population stratified by age, gender, education, and area of residence (urban/rural) in China. SF-6Dv2 and EQ-5D-5L responses were converted to utility values using the corresponding Chinese value sets. Utility values for both measures and EQ VAS scores were summarized by age and gender, and then described by different social-demographic characteristics and chronic conditions.

RESULTS

A total of 3397 respondents (51.2% male, age range 18-90 years) were included. 420 (12.4%) and 1726 (50.8%) respondents reported no problems on all SF-6Dv2 and EQ-5D-5L dimensions, respectively. The mean [standard deviation (SD)] utility values were 0.827 (0.143) for SF-6Dv2 and 0.946 (0.096) for EQ-5D-5L. The mean (SD) EQ VAS score was 87.1 (11.5). Respondents who resided in rural areas, were married, and were employed had higher utility values. Respondents with memory-related diseases or stroke had lower utility values than those with other chronic conditions. Utility values decreased with the increase in the number of chronic conditions.

CONCLUSION

This study reports the first Chinese population norms for the EQ-5D-5L and SF-6Dv2 derived using a representative sample of the Chinese general population. The norms can be used as references for economic evaluations and healthcare decision-making in China.

The Association Between Health Literacy and Self-rated Health Among Residents of China Aged 15-69 Years

INTRODUCTION

Health literacy is a critical determinant of health. However, the association between health literacy and outcomes among Chinese residents has not been studied using nationally representative data. This study examines the association between health literacy and self-rated health among Chinese residents based on the 2017 China Health Literacy Survey.

METHODS

The 2017 China Health Literacy Survey was conducted among non-institutionalized residents aged 15-69 years from 31 provinces in China. Self-rated health was measured using a single question with a 1-5 scale. Health literacy was assessed using the Chinese Health Literacy Scale. Multilevel linear regression models examined the association between health literacy and self-rated health. Data were collected in 2017 and analyzed between 2018 and 2019.

RESULTS

The final sample size was 85,384. The overall weighted mean of the self-rated health score was 4.02 (95% CI=4.00, 4.03). After adjusting for individual-, county-, and province-level covariates, Chinese residents with higher levels of health literacy were more likely to have better self-rated health (β=0.0007, SE=0.0002, p<0.001). Of 6 dimensions of health literacy, 4 (i.e., infectious diseases literacy, chronic diseases literacy, medical care literacy, and health information literacy) were associated with self-rated health. Additionally, self-rated health was associated with gender, age, education, occupation, annual household income, and chronic conditions.

CONCLUSIONS

Using nationally representative data collected in 2017, this study found that self-rated health is associated with health literacy among Chinese residents aged 15-69 years. The promotion of health literacy should be an important component of health education, patient management, and health promotion.

Investigating the Self-Reported Health Status of Domestic and Overseas Chinese Populations during the COVID-19 Pandemic

To control the spread of COVID-19, governments in different countries and regions implemented various types of lockdown and outdoor restrictions. The research aimed to describe and compare the health status of Chinese people both domestically and abroad in this global health crisis. An online questionnaire survey was distributed to Chinese mainland citizens living in Hubei (the lockdown province), outside Hubei, and those living abroad in 2020. A total of 1000 respondents were recruited and reported worse health status compared with Chinese population norms. People living in Hubei reported worse health status than those living outside Hubei but revealed better health status than overseas respondents. It was clear that the pandemic as well as strict lockdown and outdoor restriction policies affected Chinese people's health. It is important for the Chinese government to be aware of the negative impact of such strict policies and to take measures to reduce the panic of society when implementing similar policies in the future. It also implies that governments in other countries should promote social support for those who live far from home and actively call for support for non-discriminatory attitudes toward ethnic minorities.

Can physical activity compensate for low socioeconomic status with regard to poor self-rated health and low quality-of-life?

Background

Both high socioeconomic status (SES) and high physical activity (PA) are associated with better self-rated health (SRH) and higher quality-of-life (QoL).

Aim

To investigate whether high levels of PA may compensate for the association between low SES and subjective health outcomes in terms of poorer SRH and lower QoL.

Method

Data from a cross-sectional, population-based study (n = 5326) was utilized. Multiple logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for the associations between indicators of SES (economic situation and educational level), SRH and QoL, as well as between the combination of SES and PA in relation to SRH and QoL.

Result

Participants with high PA and economic problems had approximately the same OR for good SRH as those with low PA and without economic problems (OR 1.75 [95% CI 1.20–2.54] and 1.81 [1.25–2.63] respectively). Participants with high PA and low education had higher odds for good SRH (OR 3.34 [2.96–5.34] compared to those with low PA and high education (OR 1.46 [0.89–2.39]).Those with high PA and economic problems had an OR of 2.09 [1.42–3.08], for high QoL, while the corresponding OR for those with low PA and without economic problems was 4.38 [2.89–6.63].

Conclusion

Physically active people with low SES, had the same or even better odds to report good SRH compared to those with low PA and high SES. For QoL the result was not as consistent. The findings highlight the potential for promotion of PA to reduce SES-based inequalities in SRH.

EQ-5D-5L norms for the urban Chinese population in China

BACKGROUND

To generate Chinese population norms for the EQ-5D-5L dimensions, EQ-VAS (Visual Analogue Scale) scores and EQ-5D-5L index scores, stratified by gender and age. The EQ-5D is a widely used generic health-related quality of life instrument to describe population health and health outcomes in clinical trials and health economic evaluations. Currently, there are no EQ-5D-5L population norms for China.

METHODS

This norm study utilized the data collected in an EQ-5D-5L valuation study in China between December 2012 and January 2013. In the valuation study, respondents were asked to report their own health states using the EQ-5D-5L descriptive system and the EQ-VAS. Respondents' demographic information was also collected. The EQ index score was calculated using the EQ-5D-5L value set based on the Chinese urban population. Norm scores were reported by important demographic variables.

RESULTS

The mean EQ-VAS scores ranged between 88.3 for males of < 19 years and 82.9 for females of 60-69 years. Contrary to other population studies, females reported higher EQ-VAS scores than males in every age group except for 20-29 years. The mean EQ-5D-5L index values ranged from 0.912 for females of > 70 years to 0.971 for females of 30-39 years. Respondents reported more problems in the dimensions 'pain/discomfort' and 'anxiety/depression' than in the dimensions 'mobility', 'self-care' and 'usual activities' in all age groups.

CONCLUSIONS

The population norm scores for the EQ-5D can be used as reference values for comparative purposes in future Chinese studies. Further research into rural and/or a more representative population is warranted.

Self-rated health predicts decline in instrumental activities of daily living among high-functioning community-dwelling older people

Background

self-rated health (SRH) is a strong predictor of mortality, but it is unclear if SRH independently predicts a decline in instrumental activities of daily living (IADL).

Objective

to verify whether SRH is an independent predictor of IADL decline.

Design

a population-based longitudinal cohort study.

Setting

two local municipalities in Nara, Japan.

Subjects

community-dwelling older adults 65 years or older (2,638 males and 3,346 females) with independent IADL at baseline.

Methods

SRH was assessed using a single-item measure. IADL was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Multiple logistic regressions were used to examine the association of SRH with IADL decline.

Results

during the 3-year follow-up, 13.2% of males and 8.2% of females developed IADL decline. After adjusting for age, family, body mass index, economic situations, chronic diseases, alcohol, smoking, depression, cognitive functioning and ADL, poorer SHR was significantly associated with IADL decline in both genders. Compared with very good SRH, the odds ratios of good, poor and very poor were 1.69 (95% confidence interval: 1.14-2.51), 2.10 (1.25-3.55) and 3.11 (1.50-6.45) for males, and 0.88 (0.54-1.42), 2.08 (1.16-3.75) and 3.42 (1.57-7.42) for females, respectively. Significant associations were not affected by chronic diseases, cognitive functioning or ADL but observed only among subjects aged 65-74 or those without depression.

Conclusions

this study confirms that SRH is an independent predictor of IADL decline among non-disabled community-dwelling older adults. Our findings suggest that SRH is an effective tool for identifying older people with future risk for IADL decline, particularly among the young-old or those without depression.
