(tl;dr – none of the public health foundations made sense – until they did.)
It’s Day 2 of Public Health Week 2026, and I still had some more teaching to do today. Among the theories, concepts and practice tools I teach is PRECEDE-PROCEED, one of the bedrock planning tools taught in public health programs for the past several decades. PRECEDE-PROCEED prescribes a series of data reviews and needs assessments to ensure that the intervention is evidence-based and appropriate for the population being reached. I was learning all of this with my other core public health courses during Public Health 1996 – and to be honest…
None of it made a bit of sense back then. I was so distracted and bored, and kept thinking, “why can’t we get to the GOOD part and go out there and do something?”
Ah, young and blissfully oblivious early-20-something me... I didn’t know was that creating the evidence-base for those public health policies and program that actually do something IS the good part!
What I didn’t understand back then is that it is absolutely important to have a strong evidence base that supports why you’re creating and/or advocating for a public health program and policy in the first place! There has to be a documented need based on epidemiological and census data, a review of (un) available community resources, and a careful analysis of the demographic, economic, political, environmental, and social factors that contribute to negative health outcomes. Furthermore, it’s vital to understand root causes that contribute to these issues (and no – it’s not just about “willpower” and “diet and exercise”).
Organizations already collect information – like, the number of people participating in an event, or customer satisfaction surveys – that can review and analyze to guide how they can plan activities that will make an impact. Fortunately, we can now use our phones to access a lot of epidemiological and census data that are (still) available online, along with peer-reviewed articles that detail successful interventions and how they were developed. A strong evidence base, complete with accurate data and thorough needs assessments, actually can increase the chances of public health strategies being impactful and sustainable in the long run - because the goals, objectives, and activities are rooted in facts and proven public health theory, coupled with documented community need.
Looking back, I guess I was paying attention after all!
Tomorrow I’ll talk about something that was created AFTER I graduated from UCLA that really brought it all together.
