Cognitive decline affects 14.8% of Lebanese older adults. Factors like age, female sex, heart disease, and depression increase risk, while smoking may offer protection in older individuals.
Area of Science:
- Gerontology
- Public Health
- Neuroscience
Background:
- Population aging globally is increasing dementia prevalence.
- Cognitive decline poses a significant public health challenge.
- Understanding determinants of cognitive decline in specific populations is crucial.
Purpose of the Study:
- To assess the prevalence of cognitive decline among Lebanese older adults.
- To identify socio-demographic, clinical, and behavioral factors associated with cognitive decline in this population.
Main Methods:
- Secondary analysis of cross-sectional data from 502 Lebanese elders.
- Cognitive decline assessed using the Arabic Version of the 16-item Informant Questionnaire on Cognitive Decline for the older adults (A-IQCODE 16).
- Multivariable logistic regression used to identify associated factors.
Main Results:
- 14.8% of Lebanese older adults exhibited cognitive decline (A-IQCODE 16 score < 3.34).
- Higher odds of cognitive decline were linked to increased age, being female, heart disease, and depression.
- Smoking (pack-years) demonstrated a protective effect, particularly in those over 75.
Conclusions:
- Public health interventions targeting cardiovascular risk factors and depression screening are recommended.
- Differential survival bias may explain the unexpected protective effect of smoking.
- Further research is needed to clarify the role of smoking in cognitive decline.

Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
