Permissive flexibility in successful lifelong weight management : A qualitative study among Finnish men and women
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.

Associations of nutrition and body composition with cardiovascular disease risk factors in soldiers during a 6-month deployment
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
Ravitsemustutkijat kovilla julkisessa keskustelussa
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

Keripukki tappoi arviolta kaksi miljoonaa merimiestÀ Kolumbuksen ajoista 1800-luvulle saakka. Siihen saattoi pitkillÀ merimatkoilla menehtyÀ jopa puolet miehistöstÀ. VÀhitellen kokeilujen kautta ymmÀrrettiin, ettÀ tuore ruoka saattaa ehkÀistÀ keripukkia
ElÀvÀ arkisto - kansakunnan muistot klikkauksen pÀÀssÀ
Yleisradion ElÀvÀ arkisto on yksi internetissÀ toimivista maailman arkistopalveluista, joissa nostalgiasta kiinnostuneet voivat nÀhdÀ nuoruuden ja lapsuuden suosikkisarjojaan ja muistella historiallisesti merkittÀviÀ pÀiviÀ.
TÀmÀn tutkimustyyppisen opinnÀytetyön tarkoituksena on verrata ElÀvÀÀ arkistoa kahteen ulkomaalaiseen arkistopalveluun. Kun erot ja yhtÀlÀisyydet nÀiden kolmen palvelun vÀlillÀ on selvitetty, tehdÀÀn ElÀvÀlle arkistolle kehitysehdotuksia.
Tutkimuksessa ElĂ€vĂ€n arkiston verrokkikohteiksi on valittu Ruotsin julkisen palvelun televisioyhtiö SVT:n arkistopalvelu Ăppet 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 niitÀ erikseen: miltÀ ne nÀyttÀvÀt, miten niitÀ kÀytetÀÀn ja niin edelleen. Havainnoinnin jÀlkeen jokaisesta palvelusta haastateltiin yhtÀ edustajaa selittÀmÀÀn tarkemmin, miksi palvelu on juuri sellainen kuin se on. Haastattelut toteutettiin teemahaastatteluina ja toisistaan poikkeavin metodein, sillÀ kaikki haastateltavat olivat eri maissa.
Havainnoinnista ja haastatteluista saatujen tietojen avulla kolmen palvelun eroja ja yhtÀlÀisyyksiÀ kÀsiteltiin ennalta valittujen teemojen kautta. Teemat ovat palveluiden ulkoasu, kÀyttÀminen, ohjelmatarjonta, palveluissa työskenteleminen, niiden uudistukset sekÀ niiden kohtaamat haasteet.
Tulosten perusteella ElÀvÀllÀ arkistolla menee maailman arkistopalveluna oikein hyvin, sillÀ se nauttii Yleisradion sisÀistÀ ja ulkoista arvostusta ja palvelussa on monipuolista ohjelmaa draamasta lastenohjelmiin ja uutisiin. TÀstÀ syystÀ kehitysehdotuksia ei tullut kuin muutamia. NiitÀ ovat entistÀ laajempien oikeuksien tavoittelu draama- ja viihdeohjelmien esittÀmiseen sekÀ kaksi uutta palvelua ja tapaa jÀsentÀÀ ElÀvÀn arkiston sisÀltöÀ.
Jatkotutkimuksiksi ehdotetaan ElĂ€vĂ€n arkiston tutkimista opetuskĂ€ytössĂ€ sekĂ€ laajaa kĂ€yttĂ€jĂ€tutkimusta, jossa selvitetÀÀn, kumpi ruokkii ihmisten nostalgiannĂ€lkÀÀ paremmin â lapsuudessa ja nuoruudessa nĂ€hdyt televisiosarjat vai tĂ€rkeĂ€stĂ€ historiallisesta tapahtumasta kertovat uutisklipit?Yleisradioâs 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 ElÀvÀ 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 ElÀvÀ arkisto based on these findings.
The two services compared to ElĂ€vĂ€ arkisto are the Swedish public service television company Sveriges Television ABâs archive service, Ăppet arkiv, and the Canadian public broadcasting company CBC/Radio-Canadaâs 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 â 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. Itâs respected inside and outside of Yle, and it offers diverse programs, from drama and kidsâ pro-gramming to news clips. For this reason there were only a few development recom-mendations â 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€ arkistoâs 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 oneâs childhood and youth or news clips regarding historically important events
