  • Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016: a pooled analysis of 2416 population-based measurement studies in 128·9 million children, adolescents, and adults
  • 2017
  • Ingår i: Lancet (London, England). - 1474-547X. ; 390:10113, s. 2627-2642

    • BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults.METHODS: We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5-19 years. We used a Bayesian hierarchical model to estimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5-19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity).FINDINGS: Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (-0·01 kg/m(2) per decade; 95% credible interval -0·42 to 0·39, posterior probability [PP] of the observed decrease being a true decrease=0·5098) in eastern Europe to an increase of 1·00 kg/m(2) per decade (0·69-1·35, PP>0·9999) in central Latin America and an increase of 0·95 kg/m(2) per decade (0·64-1·25, PP>0·9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0·09 kg/m(2) per decade (-0·33 to 0·49, PP=0·6926) in eastern Europe to an increase of 0·77 kg/m(2) per decade (0·50-1·06, PP>0·9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0·7% (0·4-1·2) in 1975 to 5·6% (4·8-6·5) in 2016 in girls, and from 0·9% (0·5-1·3) in 1975 to 7·8% (6·7-9·1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9·2% (6·0-12·9) in 1975 to 8·4% (6·8-10·1) in 2016 in girls and from 14·8% (10·4-19·5) in 1975 to 12·4% (10·3-14·5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22·7% (16·7-29·6) among girls and 30·7% (23·5-38·0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44-117) million girls and 117 (70-178) million boys worldwide were moderately or severely underweight. In the same year, 50 (24-89) million girls and 74 (39-125) million boys worldwide were obese.INTERPRETATION: The rising trends in children's and adolescents' BMI have plateaued in many high-income countries, albeit at high levels, but have accelerated in parts of Asia, with trends no longer correlated with those of adults.FUNDING: Wellcome Trust, AstraZeneca Young Health Programme.

  • Exclusive breastfeeding of low birth weight infants for the first six months : infant morbidity and maternal and infant anthropometry
  • 2011
  • Ingår i: Asia Pacific Journal of Clinical Nutrition. - 0964-7058 .- 1440-6047. ; 20:1, s. 62-68
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: to report anthropometry and morbidity among term low birth weight infants and anthropometry of their first time mothers during the first six months in relation to breastfeeding practice. Methods: we examined data from a randomized controlled trial in Manila, the Philippines. Of the 204 mothers randomized, 68 mothers received eight postpartum breastfeeding counseling sessions, the rest did not. Maternal and infant anthropometric data at birth, 2, 4 and 6 months were taken. During seven follow-up hospital visits, an independent interviewer recorded feeding data. Results: the 24 infants exclusively breastfed from birth to six months did not have diarrhea compared to 134 partially breastfed (mean 2.3 days) and 21 non-breastfed infants (mean 2.5 days). Partially breastfed and non-breastfed infants compared to exclusively breastfed infants had more frequent, as well as more severe episodes of respiratory infections. At six months, neither overall gain in infant weight, length and head circumferences nor mean maternal weight and body mass index differed significantly between the feeding groups. Conclusions: exclusive breastfeeding for 6 months can be recommended in term low birth weight infants, who were protected from diarrhea, had fewer respiratory infections, required no hospitalization and had catch up growth. Exclusively breastfeeding mothers did not differ from mothers who breastfed partially or those who did not breastfeed with regard to weight changes at six months.

  • Conveying Emotions by Touch to the Nao Robot A User Experience Perspective
  • 2018
  • Ingår i: Multimodal Technologies and Interaction. - M D P I AG. - 2414-4088. ; 2:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Social robots are expected gradually to be used by more and more people in a widerrange of settings, domestic as well as professional. As a consequence, the features and qualityrequirements on human–robot interaction will increase, comprising possibilities to communicateemotions, establishing a positive user experience, e.g., using touch. In this paper, the focus is ondepicting how humans, as the users of robots, experience tactile emotional communication with theNao Robot, as well as identifying aspects affecting the experience and touch behavior. A qualitativeinvestigation was conducted as part of a larger experiment. The major findings consist of 15 differentaspects that vary along one or more dimensions and how those influence the four dimensions ofuser experience that are present in the study, as well as the different parts of touch behavior ofconveying emotions.

  • Ingår i: International Journal of Ambient Computing and Intelligence (IJACI). - I G I Global. - 1941-6237. ; 8:2, s. 12-31

    • Socially interactive robots are expected to have an increasing importance in human society. For social robots to provide long-term added value to people’s lives, it is of major importance to stressthe need for positive user experience (UX) of such robots. The human-centered view emphasizes various aspects that emerge in the interaction between humans and robots. However, a positive UX does not appear by itself but has to be designed for and evaluated systematically. In this paper, the focus is on the role and relevance of UX in human-robot interaction (HRI) and four trends concerning the role and relevance of UX related to socially interactive robots are identified, and three challenges related to its evaluation are also presented. It is argued that current research efforts and directions are not sufficient in HRI research, and that future research needs to further address interdisciplinary research in order to achieve long-term success of socially interactive robots.

    • In the present study, 64 users were asked to convey eight distinct emotion to a humanoid Nao robot via touch, and were then asked to evaluate their experiences of performing that task. Large differences between emotions were revealed. Users perceived conveying of positive/pro-social emotions as significantly easier than negative emotions, with love and disgust as the two extremes. When asked whether they would act differently towards a human, compared to the robot, the users’ replies varied. A content analysis of interviews revealed a generally positive user experience (UX) while interacting with the robot, but users also found the task challenging in several ways. Three major themes with impact on the UX emerged; responsiveness, robustness, and trickiness. The results are discussed in relation to a study of human-human affective tactile interaction, with implications for human-robot interaction (HRI) and design of social and affective robotics in particular.

  • Att sätta döden ur spel En analys av Tomas Tranströmers dikt "Medeltida motiv"

    • To knock Death out of the Game. An analysis of Tomas Tranströmer’s poem “Medieval motif ”The Swedish poet Tomas Tranströmer’s (1931–2015) poem “Medieval Motif ”, from For Living and Dead (1989), takes its visual point of departure in the motif “Man who plays chess with Death about his life”. A motif also found in medieval visual arts (Albertus Pictor, 1440–1509) and in modern film art (Ingmar Bergman, 1918–2007). In both Pictors painting, ”The Game of Chess with Death” (around 1480), and Bergman’s film The Seventh Seal (1957), Death knocks man out of the game by checkmate. In Tranströmer’s poem, however, things turn out somewhat differently. In “Medieval Motif ” there is unique word in Swedish poetry, “frisörsaxklippande” (“barber-scissor-like clipping”), as a determination for a sound. The analysis of the poem tries to answer a number of questions: What is this sound exactly? Why does the sound occur in a poem about a motif from the Middle Ages? What function does the sound have for the poem as an artistic whole? The “Medieval motif ”, which besides the title consists of two Sapphic stanzas, is the subject of an in-depth motif analysis and of a composition analysis. In summary, the analysis shows that the “Medieval motif ” forms an epiphany where the motif of Vanitas contributes to the understanding of the moment of togetherness as time and space cease to exist, and a previously hidden truth is revealed. As a part of that truth, Death is knocked out of the game.

  • Living with heart failure without realising : A qualitative patient study
  • 2012
  • Ingår i: British Journal of Community Nursing. - MA Healthcare Ltd.. - 1462-4753. ; 17:12, s. 630-637
  • Tidskriftsartikel (refereegranskat)abstract
    • Heart failure is an important problem in Swedish primary healthcare as in the UK. In spite of that little is known about how people with heart failure experience support from primary healthcare. This paper investigates how people with heart failure experience support in primary healthcare. Semi structured interviews were conducted with five men and five women, born 1922-1951. The interviews were analyzed with qualitative content analysis in accordance with Graneheim and Lundman (2004). The participants experienced they had not received information about their diagnosis or about the cause of their condition. They had not been informed they had heart failure. Instead the participants believed their symptoms were caused by age, thus being part of normal ageing. They did not experience they needed care or support to cope with illness or disease. Instead their main needs for support in daily life concerned help with practical matters.There is a risk primary healthcare abandons people with heart failure meaning the patients are forced to develop strategies on their own in order to manage symptoms. When inadequately informed there is also a risk they make up their own explanations signifying possible difficulties to handle their health situation.

  • Affective Touch in Human–Robot Interaction Conveying Emotion to the Nao Robot
  • 2018
  • Ingår i: International Journal of Social Robotics. - Springer. - 1875-4791. ; 10:4, s. 473-491
  • Tidskriftsartikel (refereegranskat)abstract
    • Affective touch has a fundamental role in human development, social bonding, and for providing emotional support in interpersonal relationships. We present, what is to our knowledge, the first HRI study of tactile conveyance of both positive and negative emotions (affective touch) on the Nao robot, and based on an experimental set-up from a study of human–human tactile communication. In the present work, participants conveyed eight emotions to a small humanoid robot via touch. We found that female participants conveyed emotions for a longer time, using more varied interaction and touching more regions on the robot’s body, compared to male participants. Several differences between emotions were found such that emotions could be classified by the valence of the emotion conveyed, by combining touch amount and duration. Overall, these results show high agreement with those reported for human–human affective tactile communication and could also have impact on the design and placement of tactile sensors on humanoid robots.

    • Cognitive science is becoming increasingly central within humanfactors and ergonomics (HF&E) and there has long been a call for a more systemicperspective in the area with a somewhat broader unit of analysis. This paperpresents a case study applying the theoretical framework of distributed cognition(DCog), which shows how DCog would offer a more complete understanding ofmanufacturing within its greater context, including the social, cultural, andmaterial surroundings. This paper aims to characterize and analyse dock assemblyof forest machines as a complex socio-technical system from a DCog perspective;focusing on the creation of enacted landscapes in this particular setting. The paperalso exemplifies benefits of using the DCog framework in the manufacturingdomain as a way of grasping the assembly workers’ tacit competence and skills.

  • Effects of Visualizing Missing Data : An Empirical Evaluation
  • 2014
  • Ingår i: 18th International Conference on Information Visualisation (IV). - IEEE conference proceedings. - 978-1-4799-4103-2 ; s. 132-138
  • Konferensbidrag (refereegranskat)abstract
    • This paper presents an empirical study that evaluates the effects of visualizing missing data on decision-making tasks. A comparison between three visualization techniques: (1) emptiness, (2) fuzziness, and (3) emptiness plus explanation, revealed that the latter technique induced significantly higher degree of decision-confidence than the visualization technique fuzziness. Moreover, emptiness plus explanation yield the highest number of risky choices of the three. This result suggests that uncertainty visualization techniques affect the decision-maker and the decisionconfidence. Additionally, the results indicate a possible relation between the degree of decision-confidence and the decision-maker's displayed risk behavior.
