Barnlitteraturens tekniklandskap : En didaktisk vandring från Nils Holgersson till Pettson och Findus
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Syftet med denna studie är att utifrån ett didaktiskt perspektiv undersöka budskap om teknik i ett urval svenska skönlitterära barnböcker samt undersöka hur berättelsernas tekniksyner förhåller sig till deras natur- respektive framtidssyn. Analyserna grundar sig på sex svenska författares skönlitterära barnböcker: Selma Lagerlöf, Otto Witt, Elsa Beskow, Karl-Aage Schwartzkopf, Sven Wernström och Sven Nordqvist. Dessa böcker innehåller frågeställningar och problematiker som i dag anses betydelsefulla och relevanta inom teknikens didaktik. Studien har tre analytiska perspektiv: att identifiera tekniken som finns representerad i barnböckerna, att undersöka barnböckernas tekniksyner i förhållande till natur och framtid samt att finna gemensamma och särskiljande teman berättelserna emellan. Analyserna visar att de olika tekniksynerna i barnböckerna är mångfacetterade. Hur tekniken gestaltas kan delas in i sex övergripande teman: tekniken som metafor eller liknelse, som antropomorf, som autonom, som resultat av kreativ drivkraft, männens teknik samt som icke tidsbunden. Det förekommer också olika syn på teknik och dess inverkan på såväl individ som samhälle. Natursynen som dominerar kan beskrivas som svagt antropocentrisk och en majoritet av berättelserna förmedlar bilden av det effektiva framtidssamhället där tekniken löser människans problem. En slutsats är att barnlitteraturens tekniklandskap kan bidra till att både vidga och fördjupa det teknikdidaktiska perspektivet. Det ambivalenta budskapet i böckerna gör att teknikens mångskiftande natur lyfts fram samt problematiseras på ett sätt som läroböcker sällan gör. Skönlitterära barnböcker skulle därför kunna fungera som utgångspunkter för didaktiska diskussioner om teknikens natur samt dess inverkan på människa, samhälle och natur i såväl nutid som dåtid.

- Evidence has grown supporting the role for short sleep duration as an independent risk factor for weight gain and obesity. The purpose of the present study was to examine the relationship between sleep duration and dietary quality in European adolescents. The sample consisted of 1522 adolescents (aged 12·5-17·5 years) participating in the European multi-centre cross-sectional 'Healthy Lifestyle in Europe by Nutrition in Adolescence' study. Sleep duration was estimated by a self-reported questionnaire. Dietary intake was assessed by two 24 h recalls. The Diet Quality Index for Adolescents with Meal index (DQI-AM) was used to calculate overall dietary quality, considering the components dietary equilibrium, dietary diversity, dietary quality and a meal index. An average sleep duration of ≥ 9 h was classified as optimal, between 8 and 9 h as borderline insufficient and < 8 h as insufficient. Sleep duration and the DQI-AM score were positively associated (β = 0·027, r 0·130, P< 0·001). Adolescents with insufficient (62·05 (sd 14·18)) and borderline insufficient sleep (64·25 (sd 12·87)) scored lower on the DQI-AM than adolescents with an optimal sleep duration (64·57 (sd 12·39)) (P< 0·001; P= 0·018). The present study demonstrated in European adolescents that short sleep duration was associated with a lower dietary quality. This supports the hypothesis that the health consequences of insufficient sleep may be mediated by the relationship of insufficient sleep to poor dietary quality.

- Objective: To examine the association of breakfast consumption with objectively measured and self-reported physical activity, sedentary time and physical fitness.Design: The HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) Cross-Sectional Study. Breakfast consumption was assessed by two non-consecutive 24 h recalls and by a 'Food Choices and Preferences' questionnaire. Physical activity, sedentary time and physical fitness components (cardiorespiratory fitness, muscular fitness and speed/agility) were measured and self-reported. Socio-economic status was assessed by questionnaire. Setting: Ten European cities. Subjects: Adolescents (n 2148; aged 12.5-17.5 years). Results: Breakfast consumption was not associated with measured or self-reported physical activity. However, 24 h recall breakfast consumption was related to measured sedentary time in males and females; although results were not confirmed when using other methods to assess breakfast patterns or sedentary time. Breakfast consumption was not related to muscular fitness and speed/agility in males and females. However, male breakfast consumers had higher cardiorespiratory fitness compared with occasional breakfast consumers and breakfast skippers, while no differences were observed in females. Overall, results were consistent using different methods to assess breakfast consumption or cardiorespiratory fitness (all P <= 0.005). In addition, both male and female breakfast skippers (assessed by 24 h recall) were less likely to have high measured cardiorespiratory fitness compared with breakfast consumers (OR = 0.33; 95% CI 0.18, 0.59 and OR = 0.56; 95 % CI 0.32, 0.98, respectively). Results persisted across methods. Conclusions: Skipping breakfast does not seem to be related to physical activity, sedentary time or muscular fitness and speed/agility as physical fitness components in European adolescents; yet it is associated with both measured and self-reported cardiorespiratory fitness, which extends previous findings.

- Background/Objectives: Our objective was to describe the fluid and energy consumption of beverages in a large sample of European adolescents.Subjects/Methods: We used data from 2741 European adolescents residing in 8 countries participating in the Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study (HELENA-CSS). We averaged two 24-h recalls, collected using the HELENA-dietary assessment tool. By gender and age subgroup (12.5–14.9 years and 15–17.5 years), we examined per capita and per consumer fluid (milliliters (ml)) and energy (kilojoules (kJ)) intake from beverages and percentage consuming 10 different beverage groups.Results: Mean beverage consumption was 1611 ml/day in boys and 1316 ml/day in girls. Energy intake from beverages was about 1966 kJ/day and 1289 kJ/day in European boys and girls, respectively, with sugar-sweetened beverages (SSBs) (carbonated and non-carbonated beverages, including soft drinks, fruit drinks and powders/concentrates) contributing to daily energy intake more than other groups of beverages. Boys and older adolescents consumed the most amount of per capita total energy from beverages. Among all age and gender subgroups, SSBs, sweetened milk (including chocolate milk and flavored yogurt drinks all with added sugar), low-fat milk and fruit juice provided the highest amount of per capita energy. Water was consumed by the largest percentage of adolescents followed by SSBs, fruit juice and sweetened milk. Among consumers, water provided the greatest fluid intake and sweetened milk accounted for the largest amount of energy intake followed by SSBs. Patterns of energy intake from each beverage varied between countries.Conclusions: European adolescents consume an average of 1455 ml/day of beverages, with the largest proportion of consumers and the largest fluid amount coming from water. Beverages provide 1609 kJ/day, of which 30.4%, 20.7% and 18.1% comes from SSBs, sweetened milk and fruit juice, respectively.

- Context: Inflammatory infiltrates are sometimes present in solid tumors and may be coupled to clinical behavior or etiology. Infectious viruses contribute to tumorigenesis in a significant fraction of human neoplasias. Objective: Characterize inflammatory infiltrates and possible viral transcription in primary hyperparathyroidism. Design: From the period 2007 to 2016, a total of 55 parathyroid tumors (51 adenomas and 4 hyperplasias) with prominent inflammatory infiltrates were identified from more than 2000 parathyroid tumors in the pathology archives, and investigated by immunohistochemistry for CD4, CD8, CD20 and CD45 and scored as +0, +1 or +2. Clinicopathological data were compared to 142 parathyroid adenomas without histological evidence of inflammation. Transcriptome sequencing was performed for 13 parathyroid tumors (four inflammatory, 9 non-inflammatory) to identify potential viral transcripts. Results: Tumors had prominent germinal center-like nodular (+2) lymphocytic infiltrates consisting of T and B lymphocytes (31%) and/or diffuse (+1-2) infiltrates of predominantly CD8+T lymphocytes (84%). In the majority of cases with adjacent normal parathyroid tissue, the normal rim was unaffected by the inflammatory infiltrates (96%). Presence of inflammatory infiltrates was associated with higher levels of serum-PTH (P = 0.007) and oxyphilic differentiation (P = 0.002). Co-existent autoimmune disease was observed in 27% of patients with inflammatory infiltrates, which in turn was associated with oxyphilic differentiation (P = 0.041). Additionally, prescription of anti-inflammatory drugs was associated with lower serum ionized calcium (P = 0.037). Conclusions: No evidence of virus-like sequences in the parathyroid tumors could be found by transcriptome sequencing, suggesting that other factors may contribute to attract the immune system to the parathyroid tumor tissue.

- Rationale & ObjectivesTo identify factors influencing breakfast habits in European adolescents. Materials & MethodsThe Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) is a school based study. In 2006-2007, 3546 adolescents, 12,5-17,49 years of age, in ten European cities responded to questions about breakfast habits and determinants about eating behavior. Logistic regression and descriptive percentage are used for the analyses. Results & Findings66% of boys and 58% of girls regularly consume breakfast. Boys whose parents support them to eat healthy are more likely to consume breakfast (OR, 0.61; 95% CI, 0.43-0.85). Girls whose peers eat healthy are more likely to consume breakfast (OR, 0.68; 95% CI, 0.51-0.91). Hunger (59%), taste (57%), health (48%) and parents (45%) are the most important factors influencing adolescents’ food choices at breakfast. ConclusionsParents’ and peers’ influences should be considered in the development and testing of intervention strategies.

- Objective To examine the association between breakfast consumption and CVD risk factors in European adolescents. Design Cross-sectional. Breakfast consumption was assessed by the statement 'I often skip breakfast' and categorized into 'consumer', 'occasional consumer' and 'skipper'. Blood pressure, weight, height, waist circumference, skinfold thickness, total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C), TAG, insulin and glucose were measured and BMI, TC:HDL-C, LDL-C:HDL-C and homeostasis model assessment-insulin resistance index (HOMA-IR) were calculated. Setting The European Union-funded HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) Study. Subjects European adolescents, aged 12·50- 17·49 years, from ten cities within the HELENA study (n 2929, n 925 with blood sample, 53 % females). Results In males, significant differences across breakfast consumption category ('consumer', 'occasional consumer' and 'skipper') were seen for age, BMI, skinfold thickness, waist circumference, cardiorespiratory fitness, systolic and diastolic blood pressures, TC:HDL-C, LDL-C:HDL-C, glucose, insulin, HOMA-IR and LDL-C; in females, for cardiorespiratory fitness, skinfold thickness, BMI, insulin and HOMA-IR. In overweight/obese males significant differences were also seen for TC and LDL-C, whereas no differences were observed in non-overweight males or in females regardless of weight status. Conclusions Our findings among European adolescents confirm previous data indicating that adolescents who regularly consume breakfast have lower body fat content. The results also show that regular breakfast consumption is associated with higher cardiorespiratory fitness in adolescents, and with a healthier cardiovascular profile, especially in males. Eating breakfast regularly may also negate somewhat the effect of excess adiposity on TC and LDL-C, especially in male adolescents.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis was to study the associations of individual and socio-environmental factors with breakfast habits among adolescents on a European level. Methods: The HELENA-study (Healthy Lifestyle in Europe by Nutrition in Adolescence) is a multi-centre cross-sectional, school-based study including 3528 adolescents (aged 12.5-17.49 years) from 10 European cities inEurope. Data was collected during the 2006-2007 academic year. Breakfast habits were assessed by a computerised, self-administered, 24-h recall and by questionnaires. The whole day dietary intake, measured with the computerised 24-h recall, was evaluated by comparing a self-administered and an interviewed 24-h recall. The socio-demographical factors used were sex, age, region inEurope (southern versus northern/central), mother and father’s education and occupation, family structure and family affluence. Body composition was measured with weight, height, waist circumference and skinfold thickness. Blood pressure, cardiorespiratory fitness, blood lipids, insulin and glucose were also measured. Results: The evaluation between the self-administered and interview 24-h recall showed generally good agreement between the two methods. Few adolescents (4 %) had a ‘high-quality’ breakfast. Breakfast consumption on both recall days was reported among 77 % (24-h recall) and 55 % reported slightly disagreeing to strongly disagreeing with the statement ‘I often skip breakfast’. Younger adolescents, adolescents from the northern/central part of Europe and adolescents from families with high socio-demographical status were more likely to report consuming a ‘high-quality’ breakfast while breakfast consumption versus breakfast skipping were inappreciably associated with socio-demographical factors. Personal factors (‘hunger’, ‘taste of the food’ ‘concern for health’) and the socio-environmental factor (‘parents or guardian’) were the most important influences on the adolescents’ choice of food at breakfast. Regular ‘breakfast consumption’ was associated with higher cardiorespiratory fitness in both boys and girls, and with a healthier cardiovascular profile, especially in boys. Conclusion: The public health implications of poor breakfast consumption habits are considerable. This work highlights the need to promote breakfast, especially a ‘high-quality’ breakfast, among adolescents, particularly older adolescents, adolescents from the southern part of Europe and adolescents from families with low socio-demographical status.

Tidskriftsartikel (refereegranskat)abstract
- The aim was to investigate factors associated with breakfast habits and influences on food choices at breakfast, within the framework of the EU-funded HELENA Study in 3528 adolescents from ten cities across Europe. The statement “I often skip breakfast” and personal and socio-environmental factors hypothesized to be related to food choice at breakfast were dichotomized. Logistic regression was used to investigate the association between behavioral (skipping versus consume breakfast) and individual, personal and socio-environmental factors. Half of the adolescents (fewer girls) indicated being regular breakfast consumers. Mothers’ education and family structure were associated with breakfast consumption. Adolescents with peers who gave little or no encouragement, and boys whose parents gave encouragement, were more likely to be regular breakfast consumers. Personal factors influenced the girls more than the boys in their choice of food for breakfast and socio-environmental factors influenced younger adolescents more than older adolescents. In conclusion, a broad range of (behavioral, individual, personal and socio-environmental) factors influence breakfast habits and food choices at breakfast among European adolescents. Breakfast habits were inappreciably influenced by socio-demographical factors. These factors need to be considered in discussions surrounding the development of nutritional intervention programs intended for adolescents.

- Objective: To describe breakfast habits on food group level in European adolescents and to investigate the associations between these habits and socio-demographic factors.Design: Cross-sectional studySetting: Secondary schools from nine European cities participating in the HELENA (Healthy Lifestyle inEuropeby Nutrition in Adolescence) Study. Breakfast habits were assessed twice using a computer-based 24-h dietary recall. Adolescents who consumed breakfast on at least one recall day were classified as ‘breakfast consumers’ and adolescents who did not have anything for breakfast on either of the two recall days were considered ‘breakfast skippers’. A ‘breakfast quality-index’ to describe breakfast quality was created based on the consumption or non-consumption of: cereals/cereal products, dairy products and fruits/vegetables. The socio-demographic factors studied were sex, age, region of Europe, maternal and paternal education, family structure and family affluence.Subjects: 2672 adolescents (12-17 years, 53 % girls). Results: The majority of the adolescents reported a breakfast that scored poorly on the breakfast quality index. Older adolescents, adolescents from the southern part of Europe and adolescents from families with low socio-economic status were more likely to consume a low-quality breakfast.Conclusion: This study highlights the need to promote the consumption of a high-quality breakfast among adolescents, particularly in older adolescents, adolescents from southern Europe and to adolescents from families with low socio-economic status, in order to improve public health.
