As a result, local or national level efforts to influence health determinants can have only a limited impact and it is all too easy for the individual public health practitioner to feel powerless. Yet while public health practitioners, on their own, may indeed be comparatively powerless, together they can achieve a great deal. Part I of this glossary explores a range of issues that arise as they seek to make a difference.
