Prevalence of intellectual dysfunctioning and its correlates in a community-residing elderly population

The relationship between physical activity and polypharmacy with Ikigai in a population

The aim: The Japanese word “ikigai” indicates “something to live for” and “having a purpose in life”. Ikigai or well-being, has been associated with many positive outcomes in the physical and mental health of elderly people. In this study, the relationship between ikigai and level of physical activity and polypharmacy was examined in a Turkish population. Material and methods: Both telephonic interviews and face-to-face interviews were conducted with 307 participants (59.2 % women) who completed the Ikigai-9 Turkey Scale and provided demographic information. Results: Correlations between groups (polypharmacy vs. non-polypharmacy) were analyzed with an independent t-test and analysis of variance. The means of the ikigai scores were statistically significant in the polypharmacy (24.04±8.72) and non-polypharmacy 32.64±7.53) groups (p<0.05). The number of drugs used was negatively correlated with duration of exercise per week (1.32±1.82, correlation coefficient = 0.538, p<0.05). Conclusions: The level of ikigai was negatively correlated with polypharmacy and positively correlated with duration of physical activity. An individual’s ikigai should be assessed by healthcare providers to maximize positive outcomes later in life

The effect of modifiable healthy practices on higher-level functional capacity decline among Japanese community dwellers

This study aimed to clarify the effects of the accumulation of 8 modifiable practices related to health, including smoking, alcohol drinking, physical activity, sleeping hours, body mass index, dietary diversity, ikigai (life worth living), and health checkup status, on higher-level functional capacity decline among Japanese community dwellers. Data were derived from the National Institute for Longevity Sciences - Longitudinal Study of Aging. Subjects comprised 1269 men and women aged 40 to 79 years at baseline (1997-2000) who participated in a follow-up postal survey (2013). Higher-level functional capacity was measured using the Tokyo Metropolitan Institute of Gerontology Index of Competence (total score and 3 subscales: instrumental self-maintenance, intellectual activity, and social role). The odds ratio (OR) and 95% confidence interval (CI) for a decline in higher-level functional capacity in the follow-up study according to the total number of healthy practices were analyzed using the lowest category as a reference. Multivariate adjusted ORs (95% CIs) for the total score of higher-level functional capacity, which declined according to the total number of healthy practices (0-4, 5-6, 7-8 groups) were 1.00 (reference), 0.63 (0.44-0.92), and 0.54 (0.31-0.94). For the score of social role decline, multivariate adjusted ORs (95% CIs) were 1.00 (reference), 0.62 (0.40-0.97), and 0.46 (0.23-0.90), respectively (P for trend = 0.04). Having more modifiable healthy practices, especially in social roles, may protect against a decline in higher-level functional capacity among middle-aged and elderly community dwellers in Japan.

Association of Psychosocial Conditions, Oral Health, and Dietary Variety with Intellectual Activity in Older Community-Dwelling Japanese Adults

Background

This study examined the factors related to intellectual activity in community-dwelling elderly persons.

Methods

Self-administered questionnaires mailed to all people aged ≥65 years in a dormitory suburb in Japan (n = 15,210). The response rate was 72.2%. Analytical subjects (n = 8,910) were those who lived independently and completely answered questions about independent and dependent variables and covariates. Independent variables included psychosocial conditions (i.e., social activities, hobbies, and a sense that life is worth living (ikigai)), oral health (i.e., dental health behaviors and oral function evaluated by chewing difficulties, swallowing difficulties, and oral dryness), and dietary variety measured using the dietary variety score (DVS). A dependent variable was intellectual activity measured using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Covariates included age, gender, family structure, pensions, body mass index, alcohol, smoking, medical history, self-rated health, medications, cognitive function, depression, and falling. Logistic regression was used to estimate the odds ratio (OR) for poor intellectual activity.

Results

Poor intellectual activity was reported by 28.9% of the study population. After adjustment for covariates and independent variables, poor intellectual activity was significantly associated with nonparticipation in social activities (OR = 1.90, 95%CI = 1.61–2.24), having neither hobbies nor ikigai (3.13, 2.55–3.84), having neither regular dental visits nor daily brushing (1.70, 1.35–2.14), the poorest oral function (1.61, 1.31–1.98), and the lowest DVS quartile (1.96, 1.70–2.26).

Conclusion

These results indicate that psychosocial conditions, oral health, and dietary variety are independently associated with intellectual activity in elderly persons. The factors identified in this study may be used in community health programs for maintaining the intellectual activity ability of the elderly.

Usage des benzodiazépines chez les personnes âgées : état des connaissances

Cet article passe en revue la littérature concernant la dépendance aux benzodiazépines (BZD) chez la population des personnes âgées de 65 ans et plus. Alors que les conséquences négatives reliées à l’utilisation prolongée des BZD sont bien connues, le phénomène de la dépendance à ces substances chez cette population l’est beaucoup moins. Il n’existe toujours pas de consensus autour de la définition du problème. L’usage continu des BZD peut être davantage problématique chez les personnes âgées pour qui la tolérance aux agents chimiques diminue avec l’âge. Les facteurs de risque impliqués dans l’usage chronique sont une combinaison interactive entre les caractéristiques des aînés et celles des médecins prescripteurs. Des pistes de recherche étayées sur un changement paradigmatique sont lancées afin de bonifier la recherche dans ce domaine.

Long-term continuous use of benzodiazepines by older adults in Quebec: prevalence, incidence and risk factors

OBJECTIVE

To determine the prevalence and incidence of long-term use of benzodiazepines and to assess patient-, prescriber-, and drug-related risk factors.

DESIGN

Cohort study.

PARTICIPANTS

1,423 community-dwelling older adults in Quebec who participated in the Canadian Study of Health and Aging (CSHA1).

MEASUREMENTS

Patient characteristics were obtained from the CSHA1 database. These were linked to provincial health insurance data to ascertain benzodiazepine use and prescriber characteristics.

MAIN OUTCOME MEASURE

Use of benzodiazepines for at least 135 of the first 180 days following initiation of use.

RESULTS

Twelve-month prevalence of long-term continuous use, standardized by age and gender to the Quebec population, was 19.8%. Twelve-month cumulative incidence of long-term continuous use was 1.9%. Older patients were more likely to proceed to long-term continuous use.

CONCLUSIONS

Risk of long-term continuous use of benzodiazepines seems to increase with age. This association was found to be independent of gender, health status, anxiety, cognitive status, benzodiazepine type, and physician characteristics.
