    <r:Abstract>
      <r:Content xml:lang="sv">Miljöhälsoenkäten är en tvärsnittsstudie som visar självrapporterad förekomst av olika exponeringar, besvär och sjukdomar. Studien genomförs i samarbete mellan Institutet för miljömedicin (IMM) och Statistiska Centralbyrån (SCB), på uppdrag av Folkhälsomyndigheten. Studien som riktar sig till den vuxna befolkningen har även genomförts 2007 och 2015.

Nationella miljöhälsoenkäten 1999 skickades ut till 15 750 slumpvis utvalda personer i hela landet. Målpopulationen var alla i åldrarna 19-81 år som varit bosatta i Sverige under de senaste fem åren. För att möjliggöra jämförelser mellan länen gjordes ett slumpmässigt urval av 750 personer från vart och ett av landets 21 län. 

Frågeformulären framställdes, distribuerades och lästes in maskinellt av Enkätfunktionen vid Statistiska centralbyrån (SCB) i Örebro. Tre påminnelser skickades ut, ett tack- och påminnelsekort till alla samt två påminnelser med ny enkät till dem som inte svarat. En fjärde påminnelse skickades till dem som tillhörde grupper som efter tre påminnelser hade förhållandevis låg svarsfrekvens. 

Frågeformuläret bestod av 71 frågor om boende, besvärsupplevelser, hälsotillstånd, rök- och kostvanor samt arbete och utbildning. Av de 15496 personer som mottog enkäten svarade 11233 vilket ger en total svarsfrekvens på 72,5 %.

Syfte:

Syftet var att kartlägga miljöexponering och miljörelaterad ohälsa hos den vuxna befolkningen</r:Content>
      <r:Content xml:lang="en">The environmental health survey is carried out in collaboration between the Institute of Environmental Medicine at Karolinska Institutet and the Statistics Sweden, on behalf of the Public Health Agency of Sweden. The study has also been conducted in 2007 and 2015. 

National Environmental Health Survey 1999 was sent to 15,750 randomly selected persons nationwide. The target population was all in the ages of 19-81 years who resided in Sweden for the past five years. To allow comparison between the counties, a random sample of 750 people from each of the 21 counties were performed. 

The questionnaires were prepared, distributed and read mechanically by Survey feature at Statistics Sweden (SCB) in Örebro. Three reminders were sent out, a thank you and reminder cards to all and two reminders with new questionnaire to those who have not responded. A fourth reminder was sent to those who belong to groups that after three reminders had relatively low response rate. 

The questionnaire consisted of 71 questions about housing, difficult experiences, health status, smoking and dietary habits, work and education. Of the 15,496 people who received the survey 11,233 responded, giving an overall response rate of 72.5%.

Purpose:

The aim was to chart environmental exposure and environment related illness in the adult population</r:Content>
