Body Mass Index and Waist Circumference as Predictors of Disability in Nonagenarians : The Vitality 90+ Study

2017

Background Only scarce data exist on the association between obesity and disability in the oldest old. The purpose of this prospective study is to examine if body mass index and waist circumference (WC) are associated with incident mobility and activities of daily living (ADL) disability in nonagenarians. Methods We used longitudinal data from the Vitality 90+ Study, which is a population-based study conducted at the area of Tampere, Finland. Altogether 291 women and 134 men, aged 90–91 years, had measured data on body mass index and/or WC and did not have self-reported mobility or ADL disability at baseline. Incident mobility and ADL disability was followed-up on median 3.6 years (range 0.…

Associations of cardiorespiratory fitness, physical activity, and BMI with arterial health in middle‐aged men and women

2020

We investigated the associations of cardiorespiratory fitness (CRF), physical activity (PA) with regard to aerobic and resistance training, and body mass index (BMI) with pulse wave velocity (PWV) and augmentation index (AIx) in middle‐aged adults with at least one cardiovascular risk factor. A total of 84 (46 men and 38 women) participated in the study. Cardiorespiratory fitness was measured using a maximal graded exercise test on a cycle ergometer and was defined as maximal power output (Wmax) normalized for body weight‐0.35. Participation in aerobic and resistance training was assessed by a detailed questionnaire and BMI was calculated as weight (kg)/[height (m2)]. Pulse wave velocity an…

The Effectiveness of Physical Activity-Promoting Web- and Mobile-Based Distance Weight Loss Interventions on Body Composition in Rehabilitation Setti…

2022

Background: Overweight and obesity are major problems worldwide, and they lead to an increased risk for several diseases. The use of technology in the treatment of obesity is promising, but in the existing literature, there is considerable uncertainty regarding its efficacy. In this review, we included web- and mobile-based weight loss interventions that were implemented remotely in rehabilitation settings. Objective: The aim of this systematic review is to study the effectiveness of physical activity-promoting web- and mobile-based distance weight loss interventions in rehabilitation settings on body composition in comparison with control groups that did not use technology. Methods: Studie…

Are computer and cell phone use associated with body mass index and overweight? A population study among twin adolescents

2007

Background. Overweight in children and adolescents has reached dimensions of a global epidemic during recent years. Simultaneously, information and communication technology use has rapidly increased. Methods. A population-based sample of Finnish twins born in 1983–1987 (N = 4098) was assessed by self-report questionnaires at 17 y during 2000–2005. The association of overweight (defined by Cole's BMI-for-age cut-offs) with computer and cell phone use and ownership was analyzed by logistic regression and their association with BMI by linear regression models. The effect of twinship was taken into account by correcting for clustered sampling of families. All models were adjusted for gender, ph…

Tyttöjen painonpudottaminen, painonhallintakeinot ja liikunta-aktiivisuus

2003

Tutkimuksessa selvitettiin, kuinka yleisesti 13- ja 15-vuotiaat suomalaistytöt ilmoittavat pudottavansa painoaan, millaisena he kokevat painonsa ja millaisia painonhallintakeinoja he ilmoittavat käyttävänsä. Lisäksi tutkittiin, eroavatko aktiivisesti liikkuvat tytöt painoindeksin, painon kokemisen, painonpudottamisen tai painonhallintakeinojen suhteen vähemmän liikuntaa harrastavista. Tutkimuksen aineisto on koottu WHO-Koululaistutkimuksen vuoden 2002 kyselystä, jonka otos edustaa koko Suomen seitsemäs- (N = 853) ja yhdeksäsluokkalaisia (N = 875) tyttöjä. Ylipainoisiksi luokiteltiin tytöt, joiden painoindeksi oli yhtä suuri tai suurempi kuin ikäspesifin painoindeksijakauman 85. persentiilin…

Pohjaeläinyhteisön pitkäaikaismuutokset Olkiluodon ydinvoimalaitoksen jäähdytysvesien vaikutusalueella

2010

Olkiluodon ydinvoimalaitosta ympäröivän, jäähdytysvesien otto- ja purkualueella olevan merialueen tilaa on seurattu yhtenäisin menetelmin neljän vuosikymmen ajan. Tässä tutkimuksessa tarkastellaan alueen pohjaeläinyhteisössä tapahtuneita muutoksia vuosina 1973-2009. Erityishuomio kiinnitetään ydinvoimalaitoksen jäähdytysvesien mahdollisiin suoriin ja välillisiin vaikutuksiin. Vertailualueiksi valittiin tutkimusalueen eteläpuolella sijaitsevat Rauman ja Pyhämaan merialueet. Tutkimusalueen ja vertailualueiden vedenlaatu- ja pohjaeläinaineistoja tarkasteltiin ja vertailtiin keskenään aikasarja- ja tilastoanalyysien avulla. Tulosten mukaan jäähdytysvedet eivät ole vaikuttaneet merkittävästi poh…

Network-based indices of individual and collective advising impacts in mathematics

2020

AbstractAdvising and mentoring Ph.D. students is an increasingly important aspect of the academic profession. We define and interpret a family of metrics (collectively referred to as “a-indices”) that can potentially be applied to “ranking academic advisors” using the academic genealogical records of scientists, with the emphasis on taking into account not only the number of students advised by an individual, but also subsequent academic advising records of those students. We also define and calculate the extensions of the proposed indices that account for student co-advising (referred to as “adjusted a-indices”). In addition, we extend some of the proposed metrics to ranking universities a…
