Abstract Background Chronic venous disease (CVD) and disability are worldwide problems and have significant socioeconomic implications. This study aims to analyze the time trends and social security burden of temporary work disability due to CVD in Brazil. Methods An ecological time series study using the Brazilian Social Security System database was performed from 2005 to 2014. Data from all benefits granted to workers with temporary disability due to CVD were analyzed. The cases were identified using diagnosis codes I83–I83.9 of the International Classification of Diseases 10th Revision (ICD-10). The time trend analyses were performed by the Joinpoint Regression Model, with sex, age, regions, income, and category of affiliation as variables. Crude and age-standardized rates were calculated. Results A total of 429,438 benefits were granted for temporary work disability due to CVD from 2005 to 2014, with a growing trend and an age-standardized annual percent change (APC) of 3.4 (95% CI: 2.6–4.2) (p < 0.05). Social security expense increased 3.5-fold, and the number of days in benefit doubled from 2005 to 2014. In total, 27,017,818 working days were lost. The average duration of benefits was 55.3 days. The majority of workers were women (68.2%) (p < 0.001), between 30 and 59 years old, employed, had a monthly income ≤2 minimum wages (MW) (83.2%), and lived in the regions southeast (53.6%) and south (29.3%). Significantly higher APCs were observed for women than for men (APC: 4.9, 95% CI: 4.0–5.7 versus APC: 1.2, 95% CI: 0.1–2.4). All regions in Brazil had a significant growing trend, except in the north. No significant growth was observed in the age group of 60–69 years. A decreasing trend was observed in workers with monthly incomes above 2 MW (p < 0.05). Conclusions Temporary work disability due to CVD and social security burden showed increasing trends with millions of working days lost, particularly among women and low-income workers. Preventing disability is challenging, and public policies are needed to reduce the social and economic impact of disability. Therefore, measures for promoting health at the workplace should be encouraged.
