Change in moderate alcohol consumption and quality of life: evidence from 2 population-based cohorts

[Alcohol Abstinence and Accelerated Biological Aging Among Middle-Aged and Older Adults: Evidence From the UK Biobank]

Objective

To investigate the longitudinal association between alcohol abstinence and accelerated biological aging among middle-aged and older adults and to explore the potential effect modifiers influencing the association.

Methods

Utilizing the clinico-biochemical and anthropometric data from the baseline and first repeat survey of the UK Biobank (UKB), we employed the Klemera and Doubal method (KDM) to construct the biological age (BA) and calculate BA acceleration. Change analysis based on multivariate linear regression models was employed to explore the association between changes in alcohol abstinence and changes in BA acceleration. Age, sex, smoking status, tea and coffee consumption, and body mass index were considered as the stratification factors for conducting stratified analysis.

Results

A total of 5 412 participants were included. Short-term alcohol abstinence (β=1.00, 95% confidence interval [CI]: 0.15-1.86) was found to accelerate biological aging when compared to consistent never drinking, while long-term abstinence (β=-0.20, 95% CI: -1.12-0.71) did not result in a significant acceleration of biological aging. Body mass index may be a potential effect modifier.

Conclusion

Short-term alcohol abstinence was associated with accelerated biological aging, but the effect gradually diminishes over extended periods of abstinence.

Factors associated with lower disease-specific and generic health-related quality of life in Rome IV irritable bowel syndrome

BACKGROUND

Little is known about associations with reduced quality of life in irritable bowel syndrome (IBS) or impact of IBS on quality of life compared with other chronic conditions.

METHODS

We collected demographic, gastrointestinal and psychological symptoms, healthcare usage, direct healthcare costs, impact on work and activities of daily living data from 752 individuals with Rome IV-defined IBS. We used the irritable bowel syndrome quality of life (IBS-QOL) and the EQ-5D-5L questionnaires to examine characteristics associated with lower quality of life.

RESULTS

The mean IBS-QOL among all 752 individuals with Rome IV IBS was 48.4 (SD 22.3) and the mean EQ-5D score was 0.570 (SD 0.283), the latter being comparable to people with stroke, leg ulcers or chronic obstructive pulmonary disease. Lower levels of both disease-specific and generic quality of life were associated with severe IBS symptom scores, abnormal anxiety or depression scores, and higher somatoform symptom-reporting and gastrointestinal symptom-specific anxiety scores (p < 0.001 for all analyses). Those with lower quality of life had significantly higher healthcare usage and direct healthcare costs and more impairment in work and activities of daily living (p < 0.01 for all analyses). Avoidance of alcohol, lower educational level, abnormal anxiety, depression or somatoform symptom-reporting scores, and impairment in social leisure activities, home management or maintaining close relationships were all independently associated with lower quality of life.

CONCLUSION

IBS has a substantial impact on the quality of life of those affected, and worse than observed in some severe chronic organic conditions.

Understanding longevity in Hong Kong: a comparative study with long-living, high-income countries

BACKGROUND

Since 2013, Hong Kong has sustained the world's highest life expectancy at birth-a key indicator of population health. The reasons behind this achievement remain poorly understood but are of great relevance to both rapidly developing and high-income regions. Here, we aim to compare factors behind Hong Kong's survival advantage over long-living, high-income countries.

METHODS

Life expectancy data from 1960-2020 were obtained for 18 high-income countries in the Organisation for Economic Co-operation and Development from the Human Mortality Database and for Hong Kong from Hong Kong's Census and Statistics Department. Causes of death data from 1950-2016 were obtained from WHO's Mortality Database. We used truncated cross-sectional average length of life (TCAL) to identify the contributions to survival differences based on 263 million deaths overall. As smoking is the leading cause of premature death, we also compared smoking-attributable mortality between Hong Kong and the high-income countries.

FINDINGS

From 1979-2016, Hong Kong accumulated a substantial survival advantage over high-income countries, with a difference of 1·86 years (95% CI 1·83-1·89) for males and 2·50 years (2·47-2·53) for females. As mortality from infectious diseases declined, the main contributors to Hong Kong's survival advantage were lower mortality from cardiovascular diseases for both males (TCAL difference 1·22 years, 95% CI 1·21-1·23) and females (1·19 years, 1·18-1·21), cancer for females (0·47 years, 0·45-0·48), and transport accidents for males (0·27 years, 0·27-0·28). Among high-income populations, Hong Kong recorded the lowest cardiovascular mortality and one of the lowest cancer mortalities in women. These findings were underpinned by the lowest absolute smoking-attributable mortality in high-income regions (39·7 per 100 000 in 2016, 95% CI 34·4-45·0). Reduced smoking-attributable mortality contributed to 50·5% (0·94 years, 0·93-0·95) of Hong Kong's survival advantage over males in high-income countries and 34·8% (0·87 years, 0·87-0·88) of it in females.

INTERPRETATION

Hong Kong's leading longevity is the result of fewer diseases of poverty while suppressing the diseases of affluence. A unique combination of economic prosperity and low levels of smoking with development contributed to this achievement. As such, it offers a framework that could be replicated through deliberate policies in developing and developed populations globally.

Do the successful revision surgery for humeral nonunion solve all the effects on health-related quality of life? A retrospective cohort study

Background

The aim of this study is to evaluate the effects of successful revision operation on health quality of life(QoL) and functional outcome in humeral nonunion patients.

Methods

This retrospective study included 62 patients with humeral nonunion from Northwest China, who were admitted to the Department of Trauma Surgery, Honghui Hospital between March 2013 and September 2019. The following data were retrospectively evaluated: demographic data, clinical data, imaging findings, and treatment methods. The QoL assessment indicators for humeral nonunion patients included the SF-12 mental component summary (MCS) and physical component summary (PCS),brief pain inventory-severity(BPI-S) and brief pain inventory-interference (BPI-I). The mayo elbow performance score (MEPS) was used to assess the elbow function of the patients.

Results

Successful revision surgery significantly improved the patient's PCS, MCS, BPI-S and BPI-I scores (p<0.001). According to the MEPS criteria, the excellent and good rates were 95.16% in this study. The impact of humeral nonunion on mental health was comparable with the reported impact of stroke and type II diabetes (p>0.05).The impact of post-op on physical health was comparable with the reported impact of COPD, silicosis, hypertension, barrentt’s esophagus and lower urinary tract symptoms(p>0.05).

Conclusion

Humeral nonunion is a devastating chronic medical condition that negatively affects both physical and mental health as well as quality of life. Although the effects of pain in the body can be completely relieved by treatment, the entire medical process may cause everlasting psychological trauma to the patient.

Putting the glass down may keep the stroke away: Results from a prospective cohort study in rural China

BACKGROUND AND AIMS

Most studies assess the relationship between alcohol and stroke at some point. Little is known about the effect on stroke of drinking status changes over time. This study aimed to examine the association of median 2.4-year drinking status changes with risk of stroke.

METHODS AND RESULTS

We examined 22,691 adults from rural China. Drinking status was assessed at 2004-2006 and in 2008. Participants were divided into four change patterns: consistent non-drinkers, abstainers, starters, and consistent drinkers. A Cox proportional hazards model were performed. We observed 1215 cases of stroke during a median follow-up period of 11.8 years. A faint J-shaped association between alcohol consumption and risk of stroke was found in this population. Based on the amount of alcohol consumption, only current drinkers with ≥721 g/week at baseline in both males and females had a higher risk of stroke [hazard ratio (HR): 1.342; 95% confidence interval (CI): 1.070-1.683 and HR: 2.130; CI: 1.041-4.357, respectively]. Based on change patterns, Compared with consistent non-drinkers, the HR (95% CI) for consistent drinkers, abstainers and starters was 1.298 (1.070-1.576), 1.093 (0.877-1.362) and 1.263 (1.034-1.543), respectively. The same trend was observed in male. The HR (95% CI) for consistent drinkers, abstainers and starters was 1.360 (1.098-1.685), 1.139 (0.883-1.470) and 1.364 (1.092-1.703), respectively. No difference was observed in females.

CONCLUSION

High alcohol consumption was associated with increased risk of stroke in both males and females. However, based on change patterns, consistent drinkers and starters were at higher risk of stroke only in males.
