A portrait of older adults in naturally occurring retirement communities in Ontario, Canada: A population-based study.

BACKGROUND

Naturally occurring retirement communities (NORCs) are geographical areas that have naturally become home to a large concentration of older adults. This density means that NORCs have the potential to become a pillar for aging in place strategies, but at present, there is limited data on residents and their health needs. Our objective was to describe and compare the health and healthcare use of older adults living in high-rise NORC buildings to those in all other housing types in the community.

METHODS

We conducted a population-based descriptive study of community-dwelling older adults aged ≥65 years by linking a provincial NORC registry in Ontario, Canada with health administrative records. Individuals were classified as NORC residents if their residential postal code on January 1, 2020 matched the NORC registry. Sociodemographic, clinical, and healthcare use characteristics were compared by NORC status using standardized differences (STD) and stratified by rurality, and further by age and sex in urban settings.

RESULTS

Overall, 219,995 (7.7%) of 2,869,706 older adults were NORC residents. Compared to community-dwelling older adults, NORC residents were older (mean 77.4 vs 74.6 years; STD 0.34), and more were female (61.8% vs 52.2%; STD 0.19) and had low income (16.0% vs 9.3%; STD 0.11). NORC residents also had more active chronic conditions (mean 1.9 vs 1.5; STD 0.27), medications (mean 3.4 vs 2.8; STD 0.21), home care use (15.3% vs 9.8%; STD 0.17), and primary care visits (mean 9.7 vs 7.6 visits in prior 2 years; STD 0.22). Findings were robust across rurality, age, and sex.

CONCLUSIONS

Our findings suggest that NORC residents have greater health needs than other older adults living in the community and underscore NORCs as important targets for equity-focused strategies to support aging in place.
