Decomposition of gender differences in cognitive functioning: National Survey of the Japanese elderly.

ABSTRACT:

Background

It is well known that females generally live longer than males, but women tend to suffer from more illnesses and limitations than men do, also for dementia. However, limited empirical evidence is available why this 'male-female health-survival paradox' is observed. This study aimed to investigate factors which account for gender differences in health, particularly cognitive functioning and decline among older adults.

Methods

Data were retrieved from the National Survey of the Japanese Elderly, which is a longitudinal survey of a nationwide representative sample of Japanese adults aged 60 or over. Gender differences in cognitive functioning and decline in three-year follow-ups were decomposed using Blinder-Oaxaca decomposition analysis, regarding demographic, socioeconomic, and health-related factors into the 'explained' component, by differences in individual attributes listed above, and the 'unexplained' component.

Results

Empirical analyses showed that women's lower cognitive functioning was partly explained by the endowment effect. Moreover, a shorter duration of formal education and a larger proportion with their longest occupation being domestic worker accounted for steeper cognitive decline and more prevalent mild cognitive impairment in women than in men.

Conclusion

This empirical study suggested that gender differences in cognitive functioning and decline account for different individual attributes of social determinants among men and women. Particularly, men seem to be more engaged in activities which accumulate intellectual experiences through education and occupation, as suggested by the cognitive reserve hypothesis.

Project description:BackgroundOur study aimed to map functioning and contextual factors among community-dwelling stroke survivors after first stroke, based on the International Classification of Functioning, Disability and Health (ICF), and to explore if these factors differ among older-old (75 years and older), younger-old (65-74 years), and young (18-65 years) stroke survivors.MethodsA cross-sectional population-based national survey among community-dwelling stroke survivors, 1-2 years after their first stroke. Potential participants were approached through hospital registries. The survey had 56.2% response rate. Participants (N = 114, 50% men), 27 to 94 years old (71.6±12.9 years), were categorized as: older-old (n = 51), younger-old (n = 34) and young (n = 29). They answered questions on health, functioning and contextual factors, the Stroke Impact Scale (SIS) and the Behavioural Regulation Exercise Questionnaire-2. Descriptive analysis was used, along with analysis of variance for continuous data and Fisher´s exact tests for categorical variables. TukeyHSD, was used for comparing possible age-group pairings.ResultsThe responses reflected ICF´s personal and environmental factors as well as body function, activities, and participation. Comparisons between age-groups revealed that the oldest participants reported more anxiety and depression and used more walking devices and fewer smart devices than individuals in both the younger-old and young groups. In the SIS, the oldest participants had lower scores than both younger groups in the domains of activities of daily living and mobility.ConclusionThese findings provide important information on needs and opportunities in community-based rehabilitation for first-time stroke survivors and reveal that this population has good access to smart devices which can be used in community integration. Moreover, our results support the need for analysis in subgroups of age among the heterogenous group of older individuals in this population.
