Maximizing clinical outcomes in preventive cardiology in the local community: biennial screening analysis

Background/Introduction Wartime displacement, unstable living conditions, and ongoing stress continue to reshape population health in Ukraine. Community-based screening initiatives such as the annual four-day "Health Days" provide a valuable opportunity to detect emerging health problems among both internally displaced persons and local residents. However, the effectiveness of such programs is influenced not only by health needs but also by organizational factors such as timing, weather, and location. Preliminary observations suggest that warm days, weekends, and easily accessible public spaces significantly increase public engagement. Purpose To assess how environmental and organizational conditions—specifically weather, day of the week, and type of venue—affect participation and health issue detection during "Health Days," using comparative data from the 2024 and 2025 programs. Methods A retrospective cross-sectional analysis was conducted using participation and screening data from the 2024-October (n = 9,128), 2025-June (n=10,813) and 2025-October (n = 4,592) "Health Days." For both years, demographic characteristics, the number and types of newly identified health issues, and daily participation rates were compared alongside contextual variables: ambient temperature, presence or absence of precipitation, weekday vs. weekend scheduling, and the location of screening points (outdoor public spaces vs. indoor institutional settings). The general cardivascular risk (CVR) was evaluated and analyzed in the time scale. Results Across both years, significantly higher participation was recorded on warm, sunny days and during weekend sessions. Outdoor public venues—such as parks, pedestrian zones, and central squares—attracted substantially more participants than indoor administrative or medical facilities. Higher turnout under these favorable conditions resulted in a greater number of newly detected cases of hypertension, stress-related conditions, metabolic abnormalities, and musculoskeletal complaints. In contrast, cold or rainy weather, weekday scheduling, and less accessible indoor locations were consistently associated with reduced attendance and fewer newly identified health issues. We observe the relatively stable numbers of the CVR in the time scale (45,3%-43,2%-45,6%) combined with the improved blood glucose level. Conclusions Analysis of the 2024 and 2025 "Health Days" demonstrates that environmental and organizational factors play a crucial role in determining the success of community health programs. Warm weather conditions, weekend scheduling, and the use of open public spaces markedly enhance participation and thus improve early detection of unrecognized CVR in the war-affected population with the high quantity of the hypertonic individuals.These findings should guide the planning of future social health initiatives, especially under wartime conditions where maximizing reach and accessibility is essential.
