, Week 1: Leefstijl en gezondheid
Gezondheid
Gezondheid verdeel je onder lichamelijk, sociaal en psychisch.
Gezondheid luidt als definitie gezondheid is een toestand van volledige fysieke, geestelijk
en sociaal welbevinden en niet van louter het ontbreken van ziekt.
Gezondheid wordt beïnvloed door verschillende factoren, we noemen ze
gezondheidsdeterminanten. Het Health Field Concept (Lalonde 1974) vat deze in 4
categorieën:
1. Biologische factoren
Factoren binnen het individu. Ze kunnen biologisch
bepaald of erfelijk zijn.
2. Voorzieningen in gezondheidszorg
De kwaliteit en organisatie van de gezondheidszorg
3. Leefstijl
Voedingsgewoonten, bewegingspatronen, het
omgaan met stress, alcoholgebruik, het omgaan
met relaties en persoonlijke zingevingen enz.
4. Omgeving
Samenstelling van vormgeving van woon, werk en schoolomgeving en voorzieningen
daarbinnen. Het omvat zowel de organisatie van de sociale verbanden waarin een
individu leeft en mee te maken heeft. Fysiek, sociaal cultureel, economisch en
politiek.
