    Maintaining normal weight in the current obesogenic environment is a challenge. However, some people can do it. More insight is needed to understand how and why some people succeed in long-term weight maintenance. This study uses a rare, qualitative approach by describing the thoughts of successful weight management and self-perceived requirements for success in weight maintenance. We interviewed 39 individuals who have maintained normal weight for their entire lives (men and women). The content analysis revealed a main theme: flexible, permissive and conscious self-regulation, which was divided into two subthemes (eating-related behavior and weight-related behavior). The informants reported certain routines that supported their weight management: regular eating, sufficient meal sizes, eating in response to hunger, healthy and vegetable-rich diet along with moderate feasting and flexible eating restriction. Flexibility in routines allowed freedom in their eating behavior. In addition, informants regarded themselves as physically active, and they enjoyed regular exercise. Regular weighing was generally considered unnecessary. Normal weight was regarded as a valuable and worthwhile issue, and most of the informants worked to keep their weight stable. Although the perceived workload varied among informants, the weight management strategies were similar. It was crucial to be conscious of the balance between eating and energy consumption. Further, flexibility characterized their behavior and was the basis of successful weight management. Women were more aware of weight control practices and knowledge than men, but otherwise, women and men reported similar weight management methods and attitudes. In conclusion, the interviewees who have maintained the normal weight had created a personal weight-management support environment where weight management was a lifestyle. (C) 2017 Elsevier Ltd.

    Objectives: This observational follow-up study investigated the associations of nutrition and body composition with cardiovascular disease (CVD) risk factors, including pro-inflammatory biomarkers, in soldiers during a 6-month deployment. Material and Methods: Thirty-five male soldiers were assessed at months 0, 3 and 6, and their parameters, i.e., M +/- SD, were as follows: age 30.0 +/- 8.7 years, height 179 +/- 6 cm, and BMI 24.2 +/- 2.5 kg/m(2). Three-day food diaries were used for monitoring macronutrient intake. Body composition was estimated using bioimpedance. Fasting blood samples for lipids and pro-inflammatory biomarkers were collected, and blood pressure measurements were performed. Results: Carbohydrate intake increased and protein intake decreased at month 3 (p = 0.034, p <0.001), while body composition remained stable. Systolic blood pressure increased at month 6, while other CVD risk factors remained within the reference values. Fat mass and body fat percentage were associated positively with total and low density lipoprotein (LDL) cholesterol concentrations at all measurement points. A negative association was found between the change in fiber intake vs. the change in total (r = -0.36, p = 0.033) and LDL cholesterol (R = -0.39, p = 0.019). Conclusions: Lower fiber intake and a greater amount of body fat were associated with high total and LDL cholesterol concentrations. Nevertheless, the measured CVD risk factors remained within the reference values, except for the higher systolic blood pressure. A regular screening of body composition and a higher consumption of fiber-rich foods may promote cardiometabolic health in soldiers.Peer reviewe

    Yleisradion ElĂ€vĂ€ arkisto on yksi internetissĂ€ toimivista maailman arkistopalveluista, joissa nostalgiasta kiinnostuneet voivat nĂ€hdĂ€ nuoruuden ja lapsuuden suosikkisarjojaan ja muistella historiallisesti merkittĂ€viĂ€ pĂ€iviĂ€. TĂ€mĂ€n tutkimustyyppisen opinnĂ€ytetyön tarkoituksena on verrata ElĂ€vÀÀ arkistoa kahteen ulkomaalaiseen arkistopalveluun. Kun erot ja yhtĂ€lĂ€isyydet nĂ€iden kolmen palvelun vĂ€lillĂ€ on selvitetty, tehdÀÀn ElĂ€vĂ€lle arkistolle kehitysehdotuksia. Tutkimuksessa ElĂ€vĂ€n arkiston verrokkikohteiksi on valittu Ruotsin julkisen palvelun televisioyhtiö SVT:n arkistopalvelu Öppet arkiv sekĂ€ Kanadan julkisen palvelun yleisradioyhtiö CBC/Radio-Canadan Digital Archives. Koska palvelut ovat julkisen palvelun yhtiöiden omistamia, teoriaosuudessa tarkastellaan erityisesti julkista palvelua ja siihen liittyvÀÀ keskustelua. Työ toteutettiin syksyn 2013 aikana kvalitatiiviselle eli laadulliselle tutkimukselle tyypillisin metodein. Ensin jokaista palvelua tutkittiin havainnoimalla niitĂ€ erikseen: miltĂ€ ne nĂ€yttĂ€vĂ€t, miten niitĂ€ kĂ€ytetÀÀn ja niin edelleen. Havainnoinnin jĂ€lkeen jokaisesta palvelusta haastateltiin yhtĂ€ edustajaa selittĂ€mÀÀn tarkemmin, miksi palvelu on juuri sellainen kuin se on. Haastattelut toteutettiin teemahaastatteluina ja toisistaan poikkeavin metodein, sillĂ€ kaikki haastateltavat olivat eri maissa. Havainnoinnista ja haastatteluista saatujen tietojen avulla kolmen palvelun eroja ja yhtĂ€lĂ€isyyksiĂ€ kĂ€siteltiin ennalta valittujen teemojen kautta. Teemat ovat palveluiden ulkoasu, kĂ€yttĂ€minen, ohjelmatarjonta, palveluissa työskenteleminen, niiden uudistukset sekĂ€ niiden kohtaamat haasteet. Tulosten perusteella ElĂ€vĂ€llĂ€ arkistolla menee maailman arkistopalveluna oikein hyvin, sillĂ€ se nauttii Yleisradion sisĂ€istĂ€ ja ulkoista arvostusta ja palvelussa on monipuolista ohjelmaa draamasta lastenohjelmiin ja uutisiin. TĂ€stĂ€ syystĂ€ kehitysehdotuksia ei tullut kuin muutamia. NiitĂ€ ovat entistĂ€ laajempien oikeuksien tavoittelu draama- ja viihdeohjelmien esittĂ€miseen sekĂ€ kaksi uutta palvelua ja tapaa jĂ€sentÀÀ ElĂ€vĂ€n arkiston sisĂ€ltöÀ. Jatkotutkimuksiksi ehdotetaan ElĂ€vĂ€n arkiston tutkimista opetuskĂ€ytössĂ€ sekĂ€ laajaa kĂ€yttĂ€jĂ€tutkimusta, jossa selvitetÀÀn, kumpi ruokkii ihmisten nostalgiannĂ€lkÀÀ paremmin – lapsuudessa ja nuoruudessa nĂ€hdyt televisiosarjat vai tĂ€rkeĂ€stĂ€ historiallisesta tapahtumasta kertovat uutisklipit?Yleisradio’s archive service ElĂ€vĂ€ arkisto is an internet-based archive service. Through it, users interested in nostalgia can see their favorite programs from childhood and youth and familiarize themselves with important events and dates. This study examines ElĂ€vĂ€ arkisto in comparison to two foreign archive services, look-ing at the differences and similarities among these services. It also makes some devel-opment suggestions to ElĂ€vĂ€ arkisto based on these findings. The two services compared to ElĂ€vĂ€ arkisto are the Swedish public service television company Sveriges Television AB’s archive service, Öppet arkiv, and the Canadian public broadcasting company CBC/Radio-Canada’s Digital Archives. Since these services are owned by public service companies, the thesis will also deal with public service. The study was conducted during fall 2013 using methods typical of qualitative studies. Firstly, all the three services were observed separately – what they look like, how are they are utilized and so on. After this observation, one person was interviewed from each service to ascertain why the service is the way it is. The interviews were conducted thematically and also separately, as all the interviewees were in different countries. From the information that was gathered by observation and interviews, the differences and similarities between the services were examined, based on themes decided in ad-vance, specifically how the services appear, their usage, their program content, how it is to work in these services, past and future updating of services and any obstacles they might face. According to the results, ElĂ€vĂ€ arkisto is doing great as an archive service. It’s respected inside and outside of Yle, and it offers diverse programs, from drama and kids’ pro-gramming to news clips. For this reason there were only a few development recom-mendations – the pursuing of ever broader rights to offer drama and entertainment programs, two new services and ways to interpret the content of ElĂ€vĂ€ arkisto. Future studies are suggested regarding ElĂ€vĂ€ arkisto’s usage in teaching. A deeper user study was also suggested, in order to find out which satisfies the need for nostalgia bet-ter: programs seen in one’s childhood and youth or news clips regarding historically important events

    Viimeisen kymmenen vuoden aikana on johtavissa leislÀÀketieteen ja ravitsemustieteen lehdissÀ julkaistu joitakin isoja, hyvin toteutettuja, satunnaistettuja laihdutustutkimuksia, joissa vÀhÀhiilihydraattista ruokavaliota on verrattu muihin laihdutusruokavalioihin. Alle vuoden tutkimuksissa vÀhÀhiilihydraattinen ruokavalio on ollut tehokas ja turvallinen keino laihduttaa. Sen sijaan vuoden tai kaksi kestÀneissÀ tutkimuksissa yksikÀÀn ruokavalio ei ole selkeÀsti osoittautunut muita paremmaksi
