10 months 4000IU vitamin D supplementation decreases the risk of vitamin D deficiency but has no effect to physical performance during active military training in high-latitudes – a randomized controlled trial
No full textEmbargoed til publishedBackground:
Vitamin D deficiency with related consequences to human health has growing interest to military specific researchers worldwide. Many specific conditions could put soldiers in to the higher risk of vitamin D deficiency. Under high level of physical pressure during military training might increase the need of vitamin D in human body and therefore supplementation with vitamin D could be crucial for general health and physical fitness.
Study Design:
Longitudinal, triple-blinded, randomized, controlled trial.
Methods:
113 men conscripts from the Estonian Army were randomized into two vitamin D supplementation groups: 58 to an 4000 IU and 58 to an 600 IU group. The length of the follow-up was ten months, from July 2021 until May 2022. Physical fitness and hand grip tests were performed 3 times and blood serum (25(OH)D), parathyroid hormone, calcium, ionized calcium values were measured 4 times during the study period.
Results:
The 600IU group had a significantly lower mean value of 25(OH)D in all time points during the study compared to 4000IU group (p<0.001) except baseline. Non of the study subjects in the Group A 600IU reached sufficient level of 25(OH)D in January and May. 61.3% in the 600IU and 30.6% 4000IU group had 25(OH)D levels under 50 nmol/L in May. No statistically significant differences found in the body weight and vitamin D correlation analysis in any time point on between study groups. No statistically significant differences in PTH, i-Ca were found between study groups at any time point except Ca results. No significant differences at any time points were revealed in the physical fitness test and hand grip strength tests except in non-dominant hand grip test in October.
Conclusion:
Ten months vitamin D3 4000IU supplementation decreased risk of vitamin D deficiency but had no effect to physical fitness compared to low dosage vitamin D supplementation.

Deliverable 5.1.1. Proposal for updating Estonian marine monitoring programme
No full textEesti merekeskkonna seire allprogrammi arendamisel on väga oluline roll olnud just rahvusvaheliselt
kokku lepitud merekeskkonna kaitsmise ja seisundi hindamise kohustustel nagu 1992.a vastu võetud
Läänemere piirkonna merekeskkonna kaitse konventsioon ja tänapäeval erinevad EL direktiivid:
1) Läänemere piirkonna merekeskkonna kaitse konventsioon kohustab kaitsma Läänemere
merekeskkonda kõigi reostusallikate eest ja taastama ning kaitsma selle ökoloogilist
tasakaalu, milleks on välja töötatud seire- ja hindamisstrateegia (koos vastavate seire
juhendmaterjalidega) ja Läänemere hea keskkonnaseisundi taastamise tegevuskava
(Baltic Sea Action Plan, BSAP).
2) Merestrateegia raamdirektiivi artikkel nr 11 kohustab liikmesriike kehtestama ja
rakendama koordineeritud seireprogrammi oma mereakvatooriumi keskkonnaseisundi
pidevaks hindamiseks vastavalt direktiivi III lisas toodud parameetritele (mis hõlmavad vee
füüsikalis-keemilisi omadusi, elupaigatüüpe, bioloogilisi omadusi ja muid näitajaid, sh
kemikaalidega saastumine) ja direktiivi V lisas toodud seirevajadustele ning toetudes
kehtestatud keskkonnaalastele sihtidele.
3) Veepoliitika raamdirektiivi artikkel 8 kohustab liikmesriike kehtestama seireprogrammid
vee seisundi hindamiseks, mis pinnavee puhul hõlmavad mahtu, taset või vooluhulka,
niivõrd kui see on asjakohane ökoloogilise ja keemilise seisundi ning ökoloogilise
potentsiaali puhul, ning ökoloogilist ja keemilist seisundit ning ökoloogilist potentsiaali.
4) Loodusdirektiivi artikkel 11 kohustab teostama looduslike elupaikade ja liikide
kaitsestaatuse seirekontrolli, pöörates erilist tähelepanu esmatähtsatele looduslikele
elupaigatüüpidele ja esmatähtsatele liikidele.
Merekeskkonna seire on ressursimahukas ja väga kompleksne tegevus hõlmates väga erinevate
valdkondade ekspertiisi ja logistikat. Seireprogrammi optimeerimine ja kaasajastamine on pidev
tegevus, millesse on hõlmatud nii keskkonnavaldkonna ametkonnad (Keskkonnaministeerium,
Keskkonnaagentuur, Keskkonnaamet) kui vastavad erialaekspertiisi omavad asutused (Tartu Ülikool,
Tallinna Tehnikaülikool, Eesti Keskkonnauuringute Keskus jt.). mereRITA projekti üheks eesmärgiks oli
analüüsida Eesti kehtivat merekeskkonna riikliku seire allprogrammi ja pakkuda sellele täiendusi
kulutõhusate innovaatiliste seiremeetodite rakendamise kaudu. Käesolevas aruandes on välja toodud
spetsiifilised soovitused uute meetodite rakendamiseks merekeskkonna seire allprogrammis
