Purpose: We investigated health development offices (HDOs) in Hungary as key providers of preventive healthcare services (nutrition, exercise, and mental hygiene programmes) for the general population, with a particular emphasis on health maintenance among people aged 60 and over. Materials and Methods: Our research was informed by the fact that there are currently 113 HDOs operating in Hungary. We carried out a short online survey, for which the sample size (n 5 44) was big enough to apply descriptive statistical methods and make statistically significant estimates for different age groups, using a significance level of á 5 5% for the target group. Results: Our research yielded a remarkable finding: around one in two of the clients using the services of the HDOs were over the age of 60. As many as 89% (39 out of 44) of the HDOs participating in the survey provided specific health promotion programmes for individuals over 60 years of age. Conclusions: Our research showed that HDOs are key players in the field of primary prevention among older people, suggesting that they are an important aspect of gerontological care.  Kulcsszavak: health promotion, elderly people, health development offices, gerontological care, preventive healthcare
