Self-Reported Health and Lifestyle Among Adults Aged 50+ Living in Canada: A Zeroo Health Online Survey

This article presents a cross-sectional secondary analysis of 351 completed responses to the Zeroo Health online wellness survey from adults aged 50 years and older living in Canada. It examines patterns in self-reported health, physical activity, sleep, energy, cognition, chronic-condition burden, stress recovery, perceived skin ageing, and selected sex-specific health experiences. Respondents had an estimated mean age of 70.9 years, and 79.5% were women. Most rated their health as good or excellent, reported being physically active at least three days per week, and felt fully alert within 15 minutes of waking. More frequent physical activity was consistently associated with more favourable responses across several wellness indicators, including self-rated health, energy, sleep, cognition, chronic-condition burden, and stress recovery. Age showed weaker associations with most measures, although chronic-condition burden and perceived skin ageing increased modestly with age. The findings describe patterns within a self-selected respondent sample. Because the study used cross-sectional, self-reported data and non-probability sampling, the results should not be interpreted as population prevalence estimates, causal relationships, clinical measurements, or evidence of an intervention’s effectiveness. The article also outlines directions for future research using validated measures, defined sampling strategies, longitudinal designs, and adjustment for potential confounding factors.
