Examining the Association Between Alcohol Consumption and Health Conditions in Community Dwelling Older Adults

Increased anxiolytic effect in aged female rats and increased motoric behavior in aged male rats to acute alcohol administration: Comparison to younger animals

The population of most countries in the world is increasing and understanding risk factors that can influence the health of the older population is critical. Older adults consume alcohol often in a risky, binge manner. Previous work has demonstrated that aged rats are more sensitive to many of the effects of acute ethanol. In the current project aged, adult, and adolescent female and male rats were tested on the elevated plus maze and open field following either a 1.0 g/kg alcohol injection or a saline injection. We report sex- and age-dependent effects whereas aged female rats, but not aged male rats, showed an increased anxiolytic effect of alcohol in the elevated plus maze while aged male rats, but not aged female rats, showed increased stimulatory movement in the open field. In addition, significant age effects were found for both female and male rats. It is proposed that the sex- and age-dependent effects reported in the current studies may be due to differential levels of alcohol-induced allopregnanolone for the anxiolytic effects and differential levels of alcohol-induced dopamine for the stimulatory effects. The current work provides insights into factors influencing alcohol consumption in older adults.

Assessment of Health Behaviours and Satisfaction with Life among Catholic Priests in Poland

The aim of the study was to assess the relationship between the health behaviours of diocesan priests in Poland and their level of life satisfaction. The specific goal was to determine the factors that most affect their quality of health (internal health control, the influence of others or coincidence) and life satisfaction (positive mental attitude, preventive behaviour, eating habits, health practices). The study involved 250 diocesan priests from the Podkarpackie region who took part in the research by completing an anonymous questionnaire. The questions were mainly based on tools for assessing health behaviours, namely the HBI-health behaviour inventory, MHLC-multidimensional scale of health locus of control and the SWLS-satisfaction with life scale. The general index of health behaviour of clergymen on the HBI scale was 77.12 ± 16.20 (Me = 78), showing a moderate level on the sten scale. On the MHLC health locus of control scale, the respondents believed that their health depended most on internal control: 25.27 ± 5.10 and the influence of others: 23.13 ± 5.57, are of utmost importance for their health. To a lesser extent they believed that health was dependent on chance: 17.60 ± 5.95. The SWLS satisfaction with life index was 22.51 ± 5.43 (Me = 23), also within the moderate range of the sten scale. The factors most closely related to the assessment of life satisfaction were positive mental attitudes and the overall HBI index. The health behaviours of priests measured by the HBI scale and the level of satisfaction with the life of SWLS clergymen are within a moderate range. On the MHLC scale, priests likewise believe that their health depends on themselves and then on others. They are clearly less likely to indicate accidental causes.

Chronic Intermittent Ethanol Exposure Alters Behavioral Flexibility in Aged Rats Compared to Adult Rats and Modifies Protein and Protein Pathways Related to Alzheimer's Disease

Repeated excessive alcohol consumption increases the risk of developing cognitive decline and dementia. Hazardous drinking among older adults further increases such vulnerabilities. To investigate whether alcohol induces cognitive deficits in older adults, we performed a chronic intermittent ethanol exposure paradigm (ethanol or water gavage every other day 10 times) in 8-week-old young adult and 70-week-old aged rats. While spatial memory retrieval ascertained by probe trials in the Morris water maze was not significantly different between ethanol-treated and water-treated rats in both age groups after the fifth and tenth gavages, behavioral flexibility was impaired in ethanol-treated rats compared to water-treated rats in the aged group but not in the young adult group. We then examined ethanol-treatment-associated hippocampal proteomic and phosphoproteomic differences distinct in the aged rats. We identified several ethanol-treatment-related proteins, including the upregulations of the Prkcd protein level, several of its phosphosites, and its kinase activity and downregulation in the Camk2a protein level. Our bioinformatic analysis revealed notable changes in pathways involved in neurotransmission regulation, synaptic plasticity, neuronal apoptosis, and insulin receptor signaling. In conclusion, our behavioral and proteomic results identified several candidate proteins and pathways potentially associated with alcohol-induced cognitive decline in aged adults.

Clusters of older adults with and without experience of alcohol-related harms based on affective motivations for drinking

Aim: This cross-sectional study explores profiles of community-residing Norwegian older adults (aged 62–95 years) in relation to their personally expressed motives for alcohol use. It specifically investigates drinking motives as they uniquely characterise alcohol consumers reporting problem and non-problem drinking assessed using the Drinking Problem Index (DPI). Methods: Two-step cluster analysis was used to delineate subgroups of alcohol consumers on seven drinking motivation variables, together with DPI score. The clusters were evaluated by gender, physical health and psychological health status. Results: Four clusters of alcohol consumers were identified in relation to drinking motives: Low motivated drinkers, Ambivalent drinkers, Enhancement drinkers, and Coping drinkers. For one subgroup, a strong reliance on alcohol to cope with negative feelings was most relevant to both non-problem and problem drinkers. For another subgroup, enjoying the effects of alcohol, but non-reliance on alcohol to cope with negative mood were associated with reporting drinking problems. Ambivalent drinkers reported overall low satisfaction with mental health. Very poor physical and mental health were more prevalent in men than in women characterised as Coping drinkers. Predominantly mental health status supported distinctiveness of delineated clusters. Conclusion: This study demonstrates that the classification approach to profiling of characteristics of alcohol consumers based on their motivations to drink may have a potential utility in human care settings to identify individuals who incur or may be at risk of developing alcohol-related problems in later life, and those who are not.

Associations between lifestyle factors and multidimensional frailty: a cross-sectional study among community-dwelling older people

BACKGROUND

Multidimensional frailty, including physical, psychological, and social components, is associated to disability, lower quality of life, increased healthcare utilization, and mortality. In order to prevent or delay frailty, more knowledge of its determinants is necessary; one of these determinants is lifestyle. The aim of this study is to determine the association between lifestyle factors smoking, alcohol use, nutrition, physical activity, and multidimensional frailty.

METHODS

This cross-sectional study was conducted in two samples comprising in total 45,336 Dutch community-dwelling individuals aged 65 years or older. These samples completed a questionnaire including questions about smoking, alcohol use, physical activity, sociodemographic factors (both samples), and nutrition (one sample). Multidimensional frailty was assessed with the Tilburg Frailty Indicator (TFI).

RESULTS

Higher alcohol consumption, physical activity, healthy nutrition, and less smoking were associated with less total, physical, psychological and social frailty after controlling for effects of other lifestyle factors and sociodemographic characteristics of the participants (age, gender, marital status, education, income). Effects of physical activity on total and physical frailty were up to considerable, whereas the effects of other lifestyle factors on frailty were small.

CONCLUSIONS

The four lifestyle factors were not only associated with physical frailty but also with psychological and social frailty. The different associations of frailty domains with lifestyle factors emphasize the importance of assessing frailty broadly and thus to pay attention to the multidimensional nature of this concept. The findings offer healthcare professionals starting points for interventions with the purpose to prevent or delay the onset of frailty, so community-dwelling older people have the possibility to aging in place accompanied by a good quality of life.
