Service-Learning (SL) has become a teaching methodology that promotes social and personal skills while helping groups in need and at risk of social exclusion. This paper is a systematic review of the literature on SL experiences and research on college subjects in the area of health-care promotion in settings for older adults. After an exhaustive search, 43 peer-reviewed publications were classified according to frequency and geographical distribution, sample and duration of the programs, research methodologies, data collection instruments used, and main outcomes investigated. The results indicate that the research methodologies used tended to be qualitative and mixed, while the variety of samples and duration of interventions was very broad. The instruments used were mainly interviews and questionnaires, and the programs were developed specially in the United States of America. The groups receiving most SL were healthy older adults and older adult populations with aging disabilities and illnesses. The articles in the present review highlight that SL can have a positive effect on older adults’ health promotion and can enhance their community participation.
