Which amount of vitamin D is ingested? : A quantitative study examining reported intake of vitamin D in an internet-based survey. (English)
Abstract [sv]

Bakgrund. Kostens sammansättning får en stor betydelse för boende i Sverige då de inte tillgodogör sig D-vitamin från solen i samma utsträckning som länder vid ekvatorn, speciellt vintertid. Hela 80 % av den intagna mängden D-vitamin absorberas i tarmen, ändå visar forskning på att brist föreligger i större utsträckning bland boende över 55 breddgraden.

Syfte. Studiens syfte var att undersöka hur troligt det är att boende i Sverige uppnår rekommenderat dagligt intag av D-vitamin.

Metod. För att besvara syftet utfördes en internetbaserad kvantitativ studie, baserad på en frekvensenkät. Enkäten bestod av 28 frågor, varav åtta mätte intagsfrekvens av D-vitaminrika livsmedel. Urvalet baserades på ett bekvämlighetsurval. Kön, utbildningsnivå, hemort, utlandsvistelse, träning, kosttillskott- och solskyddsanvändning testades mot tre intagsgrupper baserad på intagen mängd D-vitamin med hjälp av Chit2-test. Vidare jämfördes deltagarnas intag mot EFSA´s gränsvärden.

Resultat. Totalt inkom 144 enkätsvar av dessa rapporterade 93 % ett D-vitaminintag under rekommenderat dagligt intag (RDI). Beträffande livsmedel var lax, makrill, berikad lätt-/mellanmjölk och ägg de främsta källorna till deltagarnas uppskattade D-vitaminintag. Det var 21 % av respondenter som rapporterade ett intag under lower intake level (LI). Vidare rapporterade 32 % av respondenterna ett intag mellan LI och average requirement (AR). En mindre andel av respondenterna (n=20) hade varit utomlands under efterfrågad period. Majoriteten av respondenterna sågs använda solskyddsmedel, var aktiva och upplevde sig ha en god hälsa.

Slutsats. Det beräknades föreligga en 53-% risk att någon av deltagarna hade ett inadekvat D-vitaminintag. Ett fåtal deltagare (n=10) beräknades inta D-vitamin i enlighet med RDI.

Abstract [en]

Background. The diet is of a great importance for residents in Sweden, since they do not assimilate vitamin D from the sun to the same extent as people living in countries located at the equator. The intestine absorbs as much as 80 % of the vitamin-D intake; nevertheless the insufficiency is more common among countries above the 55 latitude.

Aim. The study aimed to investigate how likely it is that people in Sweden achieves the recommended daily intake of vitamin D.

Method. To answer the question a quantitative study approach was chosen based on a non-random selection. Frequency questionnaire consisted of a total of 28 questions; eight measured the intake frequency of D- vitamin in food. Gender, education, place of residence, educational, training, food supplements and sun block use were tested against three intake groups based on vitamin D intake with Chit2 test. Later on participants' intake was compared with the limits of EFSA.

Results. A total of 144 responded the survey, 93% of these reported a D-vitamin intake below the recommended daily intake (RDI). Food such as, salmon, mackerel, enriched easy- /semi-skimmed milk and eggs were principal sources of the participants' estimated D-vitamin intake. It was 21 % of respondents who reported an intake below lower intake level (LI). Furthermore, 32% of the respondents reported an intake between LI and average requirement (AR). A smaller proportion of the respondents (n= 20) had been abroad during requested period. The majority of the respondents were seen using sun block, was active and experienced to have a good health.

Conclusion. It might be a 53-% risks that participants have an inadequate D-vitamin intake. A small number of participants (n= 10) estimate a vitamin D intake in accordance with RDI.
