Abstract:
INTRODUCTION: Life satisfaction is a key indicator of
successful ageing and reflects well-being. There is
evidence of the association between life satisfaction and
health behaviours among older adults. Therefore, this
systematic review and meta-analysis protocol seeks to
determine the strength and direction of the association
between life satisfaction and health behaviours among
older adults.
METHODS AND ANALYSIS: This protocol followed the
Preferred Reporting Items for Systematic Review and
Meta-Analysis Protocols guidelines. We will search the
electronic databases (MEDLINE, APA PsycINFO, Web of
Science, CINAHL and Global Health) from inception to date.
Only observational studies that described the association
between life satisfaction and health behaviours—smoking,
alcohol drinking, physical activity, diet/nutrition and
sleep—will be included. Two independent reviewers
will conduct screening, data extraction and risk of
bias assessment of the articles. The risk of bias will
be assessed using the Joanna Briggs Institute critical
appraisal tools for cohort and analytical cross-sectional
studies. Studies will be included in the meta-analysis
if they report zero-order associations between life
satisfaction and health behaviours; otherwise, a narrative
synthesis will be presented.
ETHICS AND DISSEMINATION: This study does not require
ethics approval, as it involves analysing secondary data
from published studies. The completed review will be
published in a peer-reviewed journal and presented at
conferences.
TRIAL REGISTRATION NUMBER: PROSPERO
(CRD42023441386).
