Veselīga uztura „šķīvja principa” maltīšu ietekme uz ķermeņa miesas būvi raksturojošiem antropometriskiem parametriem
2021
“Šķīvja princips” tiek uzskatīts par vienu no labākajiem veidiem, kā izglītot sabiedrību par veselīga uztura pamatprincipiem (Harvard University, 2011), nodrošinot organismu ar visām nepieciešamajām uzturvielām, minerālvielām un vitamīniem. Veselīga uztura “šķīvja princips” tiek plaši pielietots un ieteikts daudzu valstu, arī Latvijas Republikas Veselības ministrijas veselīga uztura rekomendācijās. Tomēr ir vērojams zinātnisko datu un pamatojuma trūkums “šķīvja principa” atbilstības novērtējumam uztura vadlīnijām. Tādēļ šī pētījuma mērķis ir novērtēt antropometrisko parametru izmaiņas paaugstinātas augu izcelsmes produktu diētas sešu nedēļu ievērošanas rezultātā pētījuma dalībniekiem ar atš…
Guidelines for risk management in forest planning – what is risk and when is risk management useful?
2018
Managing forest resources occurs under various sources of uncertainty. Depending on the management problem, this uncertainty may have a substantial impact on the quality of the solution. As our knowledge on the sources and magnitude of uncertainty improves, integrating this knowledge into the development of management plans becomes increasingly useful, as additional information can improve the decision-making process. This adjustment requires a fundamental shift in how planning problems are viewed: instead of interpreting risk management as a technique needed only for addressing problems with natural hazards, risk management should be an integral part of most planning problems. Managing ri…
How can dementia and disability be prevented in older adults: where are we today and where are we going?
2021
Abstract Ageing of the population, together with population growth, has brought along an ample increase in the number of older individuals living with dementia and disabilities. Dementia is the main cause of disability in old age, and promoting healthy brain ageing is considered as a key element in diminishing the burden of age‐related disabilities. The World Health Organization recently launched the first risk reduction guidelines for cognitive impairment and dementia. According to recent estimates, approximately 40% of dementia cases worldwide could be attributable to 12 modifiable risk factors: low education; midlife hypertension and obesity; diabetes, smoking, excessive alcohol use, phy…
Body Composition in Late Midlife as a Predictor of Accelerated Age-associated Deficit-accumulation From Late Midlife into Old Age: A Longitudinal Bir…
2022
Abstract Background Body mass index (BMI) may not be an optimal predictor of frailty as its constituents, lean and fat mass, may have opposite associations with frailty. Methods A linear mixed model analysis was performed in the Helsinki Birth Cohort Study (n = 2 000) spanning from 57 to 84 years. A 39-item frailty index (FI) was calculated on three occasions over 17 years. Body composition in late midlife included BMI, percent body fat (%BF), waist-to-hip ratio (WHR), lean mass index (LMI), and fat mass index (FMI). Results Mean FI levels increased by 0.28%/year among men and by 0.34%/year among women. Among women, per each kg/m2 higher BMI and each unit higher %BF the increases in FI leve…
Alkoholinkäytön aiheuttama liikennekuoleman riski Suomessa
2023
Tässä tutkimuksessa analysoidaan juopumuksen asteen vaikutusta kuolemaan johtavan liikenneonnettomuuden riskiin moderneilla tilastollisilla menetelmillä. Tutkimuksen pääaineistona ovat vuosina 2005–2014 Suomessa tapahtuneet kuolemaan johtaneet moottoriajoneuvo-onnettomuudet, joissa oli mukana henkilöauto aiheuttajana tai muuna osallisena. Pääaineistoa täydennetään ratsiatutkimuksista julkaistuilla tilastoilla. Keskeisiä käytettyjä mittareita ovat riskisuhde sekä vakioitu riskisuhde, josta on poistettu sekoittavien muuttujien vaikutusta. Tutkimuksen ensimmäisenä tavoitteena on selvittää, miten pieni veren alkoholipitoisuus alkaa lisätä liikenneonnettomuuden riskiä, ja toisena tavoitteena on …

Association of developmental coordination disorder and low motor competence with impaired bone health: A systematic review.
2021
Aims Individuals with developmental coordination disorder (DCD) and low motor competence (LMC) may be at increased risk of low bone health due to their lifetime physical activity patterns. Impaired bone health increases an individual’s risk of osteoporosis and fracture; therefore, it is necessary to determine whether a bone health detriment is present in this group. Accordingly, this systematic review explores the association between DCD/LMC and bone health. Methods and Procedures Studies were included with assessment of bone health in a DCD/LMC population. Study bias was assessed using the JBI critical appraisal checklist. Due to heterogeneity, meta-analysis was not possible and narrative …
The Children of Risk Communication
2022
For the management of the COVID-19 pandemic, risk communication has been a much-needed preventive and educative action to support citizens – including children – to adopt preventive and health protective measures. However, the COVID-19 pandemic is not the only health concern at hand that has raised concerns about the health status of children and required disease-preventive strategies. Bearing in mind the mental health problems and learning losses reported during the pandemic, in this commentary, we will argue that by now, it is time to consider critically if there could be more space for positive communication and education, both alongside and as an integral part of risk communication, to…
Lifetime cumulative risk factors predict cardiovascular disease mortality in a 50-year follow-up study in Finland.
2015
Summary. Background. Systolic blood pressure, total cholesterol and smoking are known predictors of cardiovascular disease (CVD) mortality. Less is known about the effect of lifetime accumulation and changes of risk factors over time as predictors of CVD mortality, especially in very long follow-up studies. Methods. Data from the Finnish cohorts of the Seven Countries Study were used. The baseline examination was in 1959 and seven re-examinations were carried out approximately in five-year intervals. Cohorts were followed up for mortality until the end of 2011. Time-dependent Cox models with regular time-updated risk factors, time-dependent averages of risk factors and latest changes in ris…
