Using Sport and Wellness Technology to Promote Physical Activity: An Intervention Study among Teenagers
2019
Life-long physical activity patterns are established during teenage years. Thus, promoting physical activity for teenagers is important. Sport and wellness technology shows promise for promoting physical activity. Yet, its research with teenage populations is sparse. This intervention study focused on whether using a sport and wellness technology application could affect the physical activity intention of teenagers, its antecedents, and the antecedents’ effects on intention by using the theory of planned behavior combined with the concept of self-efficacy as a theoretical framework. The results showed no statistically significant difference between the intervention and the control group in …
From Intense to Leisurely Study Days : A Diary Study of Daily Wellbeing among Students in Higher Education
2020
This mobile diary study examined day-to-day variability during one study week among university students and study-related associated factors promoting and impairing their well-being. Specifically, we explored (1) what factors university students consider as promoting and as impairing their daily wellbeing, (2) what types of daily study profiles for students can be identified based on study hours, study motivation, and academic stress, and (3) how the factors promoting and impairing students’ daily wellbeing are related to these daily study profiles. The study utilized one-week mobile diary data collected from 86 university students studying in a Finnish university (a total of 602 measuremen…
Young adults personal concerns during the COVID-19 pandemic in Finland: an issue for social concern
2020
PurposeThis study focuses on how young adults face the COVID-19 pandemic by investigating their personal concerns about mental well-being, career/studies and economic situation. The authors investigated how young adults' (aged 18–29) personal concerns differ from older people's concerns (aged 30–65) and which person- and context-related antecedents relate to personal concerns.Design/methodology/approachData of Finnish young adults aged 18–29 (n = 222), who participated in the “Corona Consumers” survey (N = 1,000) in April 2020, were analyzed by path analysis and compared to participants aged 30–65 by independent samples t-test.FindingsYoung adults were significantly more concerned about the…
Leisure Consumption and well-Being among Older Adults: Does Age or Life Situation Matter?
2016
This study investigated the associations between leisure consumption and well-being in older adults (50–74 years old). To find out whether these associations are age-specific, they were compared with the associations observed among younger adults (18–49 years old). Differences between the older adults by age and life situation were also examined. This study was based on the “Finland 2014 – Consumption and Life style” survey (N = 1351), conducted among a representative sample of the Finnish adult population. Well-being was measured as mental, economic and physical well-being. Objects of leisure consumption were grouped by factor analysis, and the associations between the resulting leisure co…
Beliefs and Experiences of Individuals Following a Zero-Carb Diet
2021
The adoption of carbohydrate-restrictive diets to improve health is increasing in popularity, but there is a dearth of research on individuals who choose to severely restrict or entirely exclude carbohydrates. The present study investigated the beliefs and experiences of individuals following a diet that severely limits, or entirely excludes, dietary carbohydrates, colloquially known as a ‘zero-carb’ diet, for at least 6 months. Zero-carb dieters (n = 170) recruited via a social networking site completed an online qualitative survey prompting them to discuss their motives, rationale, and experiences of following a low-carb diet. Transcripts of participants’ responses were …
Demographic Differences in the Effectiveness of a Physical Activity Application to Promote Physical Activity: Study Among Aged People
2021
The global population is ageing and simultaneously the life expectancy at older ages is improving. To support healthy and active aging, it is imperative to find solutions to support physical activity (PA) in older age. Digital wellness technologies are a potential solution, but in order for such technologies to be successful, research is needed to gain a better understanding on their use and effectiveness among aged people. To address this need, this study investigated the effectiveness of a physical activity application to promote PA behavior among aged people of different demographics (gender, age, education, marital status). PA levels were measured before taking the application into use …
Trends in sleeping difficulty among adolescents in five Nordic countries 2002–2014
2019
Sleep has been found to be an important factor in adolescents’ mental and physical health. The aim of the present study was to examine trends in sleep difficulty (i.e., difficulty falling asleep more often than once a week) in the Nordic countries among 11- to 15-year-olds. We analysed Nordic data from the Health Behaviour in School-aged Children study (HBSC), which is conducted every four years, looking specifically at trends in sleep difficulty over a 12-year period from 2002 to 2014. The participants were aged 11 to 15 years. The total number of participants across these years was 113,447. A large percentage (17% to 31% in 2014) of adolescents in the Nordic countries experience sleep dif…
Individual differences in processes of lifestyle changes among people with obesity: an acceptance and commitment therapy (ACT) intervention in a prim…
2020
Abstract Aim: To explore what thoughts, feelings, and learning processes were involved in obese participants’ lifestyle change during an acceptance and commitment therapy (ACT) lifestyle intervention delivered in primary health care. Background: Previous studies have revealed that lifestyle interventions are effective at promoting initial weight loss, but reduced weight is often difficult to sustain because of the failure to maintain healthy lifestyle changes. Achieving and maintaining lifestyle changes requires to learn self-regulation skills. ACT-based lifestyle interventions combine many self-regulatory skill factors, and the results from previous studies are promising. Research on the i…
Directing the self-assembly of semiconducting copolymers: the consequences of grafting linear or hyperbranched polyether side chains.
2013
The synthesis and self-assembly of novel semiconducting rod-coil type graft block copolymers based on poly(para-phenylene vinylene) (PPV) copolymers is presented, focusing on the ordering effect of linear versus hyperbranched side chains. Using an additional reactive ester block, highly polar, linear poly(ethylene glycol), and hyperbranched polyglycerol side chains are attached in a grafting-to approach. Remarkably, the resulting novel semiconducting graft copolymers with polyether side chains show different solubility and side-chain directed self-assembly behavior in various solvents, e.g., cylindrical or spherical superstructures in the size range of 10 to 120 nm, as shown by TEM. By adju…
Model-based biotechnological potential analysis of Kluyveromyces marxianus central metabolism
2016
Abstract The non-conventional yeast Kluyveromyces marxianus is an emerging industrial producer for many biotechnological processes. Here, we show the application of a biomass-linked stoichiometric model of central metabolism that is experimentally validated, and mass and charge balanced for assessing the carbon conversion efficiency of wild type and modified K. marxianus. Pairs of substrates (lactose, glucose, inulin, xylose) and products (ethanol, acetate, lactate, glycerol, ethyl acetate, succinate, glutamate, phenylethanol and phenylalanine) are examined by various modelling and optimisation methods. Our model reveals the organism’s potential for industrial application and metabolic engi…
