How should we invest precious health resources? At a time when chronic illness is increasing, climate change is starting to impact our health, and inequality persists, how can health promotion help to improve health outcomes across the whole population?Health Promotion in the 21st Century offers a systematic introduction to the principles of health promotion today, and the effective planning, implementation and evaluation of programs. The authors review the global, regional and local issues that impact on health, and show how many elements in society - including social, economic, political and education - contribute to population health and wellbeing.Throughout the authors emphasise that health promotion needs multiple solutions, and that health promotion professionals should seek out strategic opportunities and partnerships. They consider the issues of vulnerable groups such as Aboriginal and Torres Strait Islander people, those with mental health issues, and the aged, and a variety of innovative tools for targeting particular populations. They also focus on strategies to ensure programs refresh and remain vibrant and sustainable in the longer term.With case studies and activities in each chapter, Health Promotion in the 21st Century is an essential resource for anyone seeking to build a career in health promotion.
