Social Determinants of Health and Preventive Service Utilization in a U.S. Community Health Center: An Application of the Andersen and Aday Model.
Article in medRxiv : the preprint server for health sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To examine how social determinants of health (SDOH) influence the utilization of preventive health services at a Federally Qualified Health Center (FQHC) in Erie, Pennsylvania, using the Andersen and Aday behavioral model (Andersen, 1995; Aday & Andersen, 1974). Methods: A cross-sectional, descriptive correlational study was conducted among adults (≥18 years) receiving primary care at Community Health Net from March through October 2018. The data was collected via a self-administered questionnaire, classifying variables as predisposing, enabling, or need factors, per the Andersen and Aday model. The Protocol for Responding to & Assessing Patients' Assets, Risks & Experiences (PRAPARE) tool was used to assess SDOH. Mental health status was measured using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder 7-item scale. Logistic regression identified predictors of preventive service utilization. Results: Of the 274 participants, 65.8% were over 50 years old, 50.2% had low annual incomes (≤$15,000), 71.0% had public insurance, 58.8% were unemployed, and 10.0% were homeless. A total of 78.8% of the participants reported experiencing emotional or physical problems that affected their social life; 16.1% reported having transportation barriers and 13.9% reported a lack of social support. Preventive service utilization was high (75.1%). Multivariable analysis showed that low incomes (≤$15,000) (odds ratio [OR] = 1.82, 95% CI [1.15, 2.89]), unemployment (OR = 2.10, 95% CI [1.30, 3.40]), and mental health conditions (OR = 3.05, 95% CI [1.80, 5.18]) were significant predictors of utilization. Homelessness showed a positive but not statistically significant association (OR = 1.68, 95% CI [0.92, 3.06). The most frequently reported unmet needs among participants were mental health care (24.8%), transportation (16.1%), and social support (13.9%). Conclusions: Socioeconomic disadvantage and mental health needs are strongly associated with preventive service utilization in this FQHC population, consistent with the Andersen and Aday model and international evidence (Braveman & Gottlieb, 2014; Marmot et al., 2008; Magnan, 2021). Addressing SDOH-including poverty, unemployment, mental health, and access barriers-remains essential for advancing health equity in high-risk communities (World Health Organization, 2008; Artiga & Hinton, 2022).
