Put simply, the ILA doesn't take into consideration social determinants (e.g. age, gender, location, ethnicity, education, SES etc). It pretty much concentrates on the provision of information and the belief that people will change once given this information (i.e. targetting knowledge, attitudes and behaviours). Also, it gives power to the health professionals such as doctors and specialists to decide what's best for the community or the individual and therefore, the individual is less empowered.
However, the NPHA focuses mainly on health promotion and the prevention rather than cure. It's more effective than the ILA because it recognises the social determinants of health such as housing, income, physical environment etc. It's effective because it:
- Empowers the individual
- Encourages community participation; and
- Recognises the social determinants of health
