Changes in the Disease Burden of Depressive Disorders Among Middle-Aged and Older Adults (Aged 45-89) in China Over 30 years: Insights From the Global Burden of Disease Study 2021

OBJECTIVES

In China, depressive disorder (DD) among middle-aged and older adults is a significant public health concern. This research utilized the latest Global Burden of Disease Study (GBD) database to evaluate the evolving disease burden of DD in this demographic over the past 3 decades.

METHODS

Data on the incidence and disability-adjusted life years (DALY) of DD among people aged 45-89 in China between 1992 and 2021 were collected from the GBD 2021. The age-period-cohort (APC) model was applied to determine the effects of age, period, and cohort on the incidence and DALY rates of DD.

RESULTS

(1) Over the last 30 years, there was a 6.49% increase in the overall age-standardized incidence rate (ASIR) and a 3.99% increase in age-standardized DALY rates (ASDR) for DD among middle-aged and older adults in China, with females consistently exhibiting higher ASIR and ASDR than males. In 2020, COVID-19 significantly increased the ASIR and ASDR of DD in the population, especially in females. (2) The APC analysis revealed an annual net drift of 0.38% in incidence and 0.17% in DALY rate. For both genders, local drifts of incidence were negative for the 45-54 age group and positive for the 55-89 age group; DALY rates showed negative local drifts for the 45-59 age group and positive for the 60-89 age group. (3) Incidence and DALY rates increased with age, displaying a trend of initial decline followed by an increase in period effects, but a trend of initial increase followed by a decrease in cohort effects. Moreover, the impacts of age, period, and cohort exhibited gender differences.

CONCLUSIONS

Our findings provide a comprehensive and in-depth perspective for studying the changing trends of DD's burden in China and for identifying targeted prevention and treatment policies for DD from different aspects.

Topic modeling and content analysis of people's anxiety-related concerns raised on a computer-mediated health platform

BACKGROUND

About one in four Chinese people might suffer or have already suffered from anxiety conditions, with a lifetime prevalence rate of 4.8%. However, many of those who could have benefited from psychological or pharmacological treatments fail to be recognized or treated due to the lack of timely recognition and accurate diagnosis.

OBJECTIVE

This study used a topic modeling approach to explore people's anxiety-related concerns raised on a computer-mediated Chinese health platform, YOU WEN BI DA (questioning and answering), to provide implications for accurate diagnosis, targeted education, tailored intervention, and informed policy-making in the course of addressing this condition of public concern.

METHODS

First, we extracted data from YOU WEN BI DA between May 2022 and February 2023. After cleaning the extracted data both using the Python text processing tool spaCy and manually, we ascertained the optimal number of topics by drawing on the coherence scores and used latent Dirichlet allocation (LDA) topic modeling to generate the most salient topics and related terms. We then categorized the topics ascertained into different classes of themes by plotting them onto a 2D plane via multidimensional scaling using the pyLDAvis visualization tool. Finally, we analyzed these topics and themes qualitatively to better understand people's anxiety-related concerns.

RESULTS

5 topics with different overall prevalence were ascertained through data analysis. Topic 2 (tinnitus phobia-incurred concerns, n = 639) is the most popular dominant topic, occurring in 25.1% of the 2545 collected concerns, closely followed by Topics 1 (neurosis-incurred concerns, n = 512;) and 3 (sleep, dyskinesia, bipolar, cognitive, and somatic disorders-incurred concerns, n = 619), which appeared in 20.1% and 24.3% of the 2545 concerns respectively. Topic 5 (social phobia-incurred concerns, n = 428) ranks as the fourth most popular dominant topic, showing up in 16.8% of the 2545 concerns. Topic 4 (autonomic nerve dysfunction-incurred concerns, n = 347) accounts for 13.6% of the 2545 concerns. The t-distributed Stochastic Neighbor Embedding analysis reveals partial similarities between Topics 2 and 5 as well as between Topics 4 and 5 because many concerns involved in Topics 2 and 5 pertain to people's psychological status of fear and anxiety and the relief and dispelling of such symptoms through medication, and many concerns involved in Topics 4 and 5 relate to people's worries about the negative impact on their nerves and the adjustment and conditioning of such effects through medication.

CONCLUSION

This was the first study that investigated Chinese people's anxiety-related concerns raised on YOU WEN BI DA using the topic modeling technique. The automatic text analysis and complementary manual interpretation of the collected data allowed for the discovery of the dominant topics hidden in the data and the categorization of these topics into different themes to reveal the overall status of people's anxiety-related concerns. The research findings can provide some practice implications for health and medical educators, practitioners, and policy-makers to make joint efforts to address this common public concern effectively and efficiently.

Promoting Geropsychology: A Memorandum for Research, Policies, Education Programs, and Practices for Healthy Aging

BACKGROUND

This viewpoint paper reports the state of the art at a global level on research, practice and assessment, policies, and training in the clinical psychology of aging and, more specifically, in geropsychology. The main sources of information were as follows: (1) the most recent reviews of the literature available in the scientific literature; (2) the resources on the internet referable to professional and academic associations dealing with the topic; and (3) the laws, policy initiatives, and funded programs that are aimed at the diffusion and applications of mental health in aging.

METHODS

The present study aims to provide an updated and comprehensive memorandum highlighting the importance of prioritizing mental health in older adults. It seeks to promote health in general and disease prevention strategies, ensuring equitable access to mental health services integrated into primary care and designed for aging. This paper also aims to shed light on the slow development process and lack of consolidation in the adaptation of academic training at master's and doctoral levels in most developed countries, despite the long-declared importance of enhancing resources for the promotion of geropsychology.

RESULTS

The results of the present study are patchy. Although the importance of enhancing resources for the promotion of geropsychology has long been declared, the development process seems very slow, and the adaptation of academic training at master's and doctoral levels in most developed countries-those that, for demographic reasons and attitudes, should be more sensitive to the issue, does not yet seem to have consolidated.

CONCLUSIONS

Collaboration among diverse professionals is crucial for providing integrated and comprehensive care to older adults that addresses their physical, psychological, and social needs.

The impact of chronic diseases on the health-related quality of life of middle-aged and older adults: the role of physical activity and degree of digitization

BACKGROUND

The incidence of chronic diseases is on the rise worldwide, with a high mortality rate in China, posing a serious threat to the health-related quality of life (HRQoL) of middle-aged and older adults. This study explores the association between chronic diseases and the HRQoL of middle-aged and older adults, as well as the role of physical activity (PA) and degree of digitization in this relationship.

METHODS

The data used in this study was obtained from the 2018 China Health and Retirement Longitudinal Study (CHARLS), which included 13,620 middle-aged and older Chinese adults (≥ 45 years). The study utilized correlation analysis, and bootstrapping to investigate the mediating role of PA and the moderating influence of the degree of digitization. Data analysis was conducted using SPSS 26.0.

RESULTS

The study findings indicate that the severity of chronic disease has a significant negative predictive effect on HRQoL (PCS, physical component summary; MCS, mental component summary) (PCS: β = -2.515, p < 0.01, MCS: β = -0.735, p < 0.01). Further analysis revealed that PA plays a mediating and masking role in the impact of chronic disease on PCS and MCS. Additionally, the degree of digitization moderates the relationship between chronic disease and PA, chronic disease and PCS, and PA and PCS.

CONCLUSION

For middle-aged and older persons, chronic diseases have a detrimental effect on their HRQoL; nevertheless, PA can help. Furthermore, proper internet usage can help older individuals to some extent in mitigating the negative impact of chronic diseases. Therefore, it is encouraged to promote PA among the elderly with chronic diseases to improve their physical health, as well as to guide them in the proper use of the Internet to establish healthy behaviors.

Trends in the disease burden of anxiety disorders in middle-aged and older adults in China

BACKGROUND

Anxiety disorders in middle-aged and older adults are an important public health concern in China. Based on the data in the global disease burden (GDB) research database, this study evaluated and analyzed the trend of the disease burden of middle-aged and older patients living with anxiety in China in the past 30 years.

METHODS

The incidence and disability-adjusted life years (DALYs) data of anxiety disorders in China for individuals aged 45-89 years were collected from the Global Burden of Disease Study 2019, and the effects of age, period, and cohort on the incidence of and DALY rate for anxiety disorders were analysed using an age-period-cohort model. Because of the COVID-19 pandemic, the global disease burden research database has not been updated since 2019. However, this did not affect the analysis of future trends in this study, which combined data in the past three decades from 1990 to 2019.

RESULTS

(1) The overall age-standardised incidence rate (ASIR) and age-standardised DALY rate (ASDR) for anxiety disorders in middle-aged and older adults in China decreased by 4.0 and 7.7% from 1990 to 2019, respectively, and the ASIR and ASDR were always higher in women than in men. (2)Age-period-cohort analysis showed that the net drifts for incidence and DALY rate were - 0.27% and - 0.55% per year, respectively. For both genders, the local drifts for incidence were lower than zero in those aged 45-79 years and higher than zero in those aged 80-89 years; the local drifts for the DALY rate were lower than zero in all groups. (3) From the 1990-1994 to 2015-2019, the relative risks of anxiety disorder incidence and DALY decreased by 5.6 and 7.3% in men and 4.3 and 11.7% in women, respectively.

CONCLUSION

The disease burden of anxiety disorders in middle-aged and older adults in China has been relieved over the past 30 years; however, recent ASDR, ASDR, period, and cohort effects have shown adverse trends. The incidence and DALY rate decreased with age in women, while men showed a trend of increasing first and decreasing afterwards.
