Background: The purpose of this study was to compare health status, lifestyle habits, and perceived social support between cancer survivors and people who have never had cancer. Methods: Descriptive, cross-sectional multicenter study nested in phases II and III of the cluster randomized clinical trial ERIA, designed to analyze the effects of a complex primary care intervention compared with care as usual on smoking cessation, improved adherence to the Mediterranean diet, and increased physical activity. For the cross-sectional study, patients were divided into two groups: cancer survivors and people who had never had cancer (controls). Thirty eight Primary care centers Spanish provinces of Barcelona, Girona, Balearic Islands, Malaga, Seville, Salamanca, Soria, Toledo, Vigo, Vizcaya, and Zaragoza. Adults aged between 45 and 75 years with at least two risk behaviors. Patients being treated for active cancer or in end-of-life care were excluded.Primary outcomes: Sociodemographic variables, diet, physical activity, smoking, body mass index, Charlson Comorbidity Index, and self-perceived health and social support.Results: Of the 4259 people included, 190 (4.46%) were cancer survivors. Their mean±SD age was 62.8±7 years versus 58.7±8 years (P<0.01) for people who had never had cancer. Long-term sick leave was also more common in this group (11.9% vs 3.5%, P<0.001). No between-group differences were observed for smoking, adherence to the Mediterranean diet, physical activity, obesity, or perceived social support. Cancer survivors reported worse health (OR 1.82; IC95% 1.02–2.75) and were more likely to have two or more comorbid conditions (OR 1.68; 95% CI 1.18–2.39), chronic pulmonary obstructive disease (OR 2.17; 95% CI 1.25–3.78), and depression (OR 1.65; 95% CI 1.06–2.57). In the multiple regression analysis, older age and worse self-perceived health continued to be significantly associated with having survived cancer.Conclusions: Cancer survivors have more chronic diseases, a greater likelihood of being on long-term sick leave, and worse self-perceived health than people without a history of cancer, regardless of age. The two groups perceived similar levels of social support.
