Background: Different protein sources can have a major impact on not only our health, but also on the environment. We also know that dietary habits learned in early childhood often carry into adulthood. A novel way to examine dietary and purchase behaviour is using loyalty card data. This thesis utilises loyalty card complied by the LoCard research group from Finland’s largest grocery chain (S-group) in assessing the protein source purchases made by Finnish families with children in 2018. Objectives: The objectives of this study were to examine what protein sources Finnish families with chil- dren purchase, and to assess whether relationships exist between different sociodemographic factors and protein source purchases, as well as the amount of money used on food purchases overall in 2018. Methods: This study utilised data from the LoCard data set which included food purchase data, as well as information on sociodemographic factors obtained from a background questionnaire. Inclusion criteria stated that self-assessed loyalty score (to S-group stores) had to be >60% to be included into this study, and the main study population could only include families with at least 1 child under 7-years of age. Overall, 7807 participants’ purchase data was received from LoCard, with 3904 being households with young children, and 3903 being control households. The statistical analysis methods utilised in this thesis study included linear regression analyses, as well as the independent samples Mann-Whitney U-test and chi-squared test. Results: Statistically significant findings included the following; Finnish families with small children had a larger share of their total protein purchases coming from dairy (30.4% of total protein), red meat (16.9%), and infant formula (0.3%), but less from plant-based protein sources (2%) compared to the control group (2.5%). In terms of sociodemographic factors, increase in household size, age and being employed were associated with increased proportion of protein from red meat purchases. Increase in educational level was associated with less protein from red meat purchases. For poultry, increase in age was associated with decreased protein from purchases. For plant-based protein sources, having an undergraduate degree or higher level of education, as well as being unemployed were associated with increased proportion of protein from purchases. Being in the highest income category and increase in age and household size were associated with decreased protein from plant-based protein source purchases. For protein coming from fish, increase in income category as well as age and having a graduate degree were associated with increased proportion of protein. Increase in household size and being employed were associated with decreased protein proportions. In terms of the money used on all food purchases, families with small children spent less money, as well as those with graduate degrees. Increase in income category, as well as in age and household size were associated with more money spent on food purchases. Conclusions: The main protein sources purchased by Finnish families with small children were dairy and red meat. Fish and plant-based protein source purchases were relatively low. Existing research is well in line with the findings of this thesis. More work needs to be done to shift diets of families with small children to adhere to the dietary guidelines more closely. Future LoCard research should include specific ages of other household members in the background questionnaire, as well as work on acquiring purchase data from other grocery chains.

Today, children in Finland live in a complex linguistic environment, which offers interesting opportunities for studying how they perceive and discuss their own and others’ language use. The objective of this study is to analyse and interpret how children express stance (Du Bois, 2007; Jaffe, 2009) in relation to language use and language skills in the context of a group interview. From the perspective of stance, interaction is viewed as the central process of meaning-making and identity construction. The study is based on qualitative, thematic focus group interviews on language use, language learning and language skills with students in second grade in a bilingual municipality in Finland. A total of 15 students participated in the study, of which 9 students attended a school with Finnish and 6 students a school with Swedish as the language of instruction. The interaction of the children is analysed from a stance perspective, aiming to demonstrate how the children use available resources to position themselves and others as language users, and how their stances can be interpreted in the sociocultural context. The results illustrate how children both implicitly and explicitly position themselves and others as language users by using social categories, topicalizing and not topicalizing language skills and by negotiating epistemic authority. In the interviews, the children positioned themselves in relation to each other and to their collectively constructed ideas about language identities, language use and language skills. The study adds to the growing body of research that applies stance theory to study how cultural and language identities are expressed in interaction, and exemplifies how stance can be used to analyse the interactions of children. It also relates to the larger discussion on how individual interactions serve as opportunities for stancetaking and meaning-making, and how they can contribute to the construction of more enduring identities and ideas.

Background: Food systems and diets affect both human health and the environment. As dietary behaviour adopted in childhood often track to adulthood, the meals served in daycare centres offer a good opportunity for promoting healthy and climate-friendly eating habits in both short- and long-term. Objectives: As part of the FoodStep project, the objectives of this study were to examine compliance with the food-level recommendations, nutrient content per child and climate impacts of the conventional menus in Finnish daycare centers, as well as the potential changes in the compliance with the food-level recommendations, nutrient content per child and climate impacts of the FoodStep menus, modified towards more plant-based diet. Methods: Menus, recipes, and planned portion sizes were used to create hypothetical food diaries, representing the planned foods per child during a full-day daycare. Nutrient calculations were performed for conventional menus and modified FoodStep menus for four Finnish municipalities. Climate impacts of the same meals were calculated at Natural Resources Institute of Finland. Results: In the conventional menus, food-level serving frequency recommendations were not met for several food groups, but the compliance was clearly improved in the modified FoodStep menus in all the municipalities. At nutrient-level, the issues in the two menus were similar in every municipality: compared to the recommendations for daycares, too low proportion of energy was derived from fat and too high from protein. In addition, the planned salt supplies were excessive. The planned supplies of energy and micronutrients fulfilled the recommendations with the only exception of iron in the conventional menu of one municipality. In three of the four municipalities, the FoodStep menu modifications led to markedly reduced climate impacts. Conclusions: More focus in daycare menu planning would be needed to meet both the food- and nutrient-level recommendations. Moderate modifications of the conventional daycare menus – increasing vegetables, fruits, and berries, and sustainable fish species and decreasing meat and dairy products – can improve the compliance with the food-level recommendations and decrease the climate impacts of the menus without negative effects on the nutrient supplies.

Background: The EAT-Lancet Commission proposed a healthy dietary pattern from environmentally sustainable food production systems to guide food system transformation. The EAT-Lancet reference diet comprises mass-based food consumption targets (both point estimates and ranges) for different food groups. Baseline assessments are required to inform the planning of the national food system transformation. Therefore, it is important to identify gaps between the targets and local food consumption. Objectives: The present study aimed to assess the current state of Finnish pre-schoolers’ diet by comparison with the reference diet’s food group level targets. Specifically, the Finnish pre-schoolers’ food consumption was estimated in the food groups of the reference diet. Methods: Data from 807 children (3- to 6-year-olds, 48% girls), were collected in the Increased Health and Wellbeing in Preschools (DAGIS) cross-sectional survey in 2015–2016. Food records, covering from one up to five complete days, were kept by parents and pre-school personnel. Detailed information on foods, such as ingredients of composite dishes and product names for packed foods were recorded. Food record data were decomposed into ingredients by AivoDiet dietary software. Industrial products, such as sausages and biscuits, were manually decomposed into ingredients by estimating the shares of ingredients using product information available on a retailer’s online database and food manufacturers’ webpages. Formulas were developed to calculate the consumption of added sugars. The consumption of dairy products was converted into milk equivalents using factors from the literature. Finally, the ingredients were manually classified into the reference diet’s food groups. The target amounts were set (separately for two age groups) in grams by proportioning the published target amounts (that assume a 2500 kcal diet) to the children’s average reported energy intake. The National Cancer Institute (NCI) method was used to calculate the daily average food consumption and the proportion of children who met targets in each food group. Results: Compared to the point estimate targets, on average, the daily food consumption for 3- to 4-year-olds (n 462) and 5- to 6-year-olds (n 345) differed for vegetables (60% of the target in both age groups); legumes and nuts (below a tenth of the target); whole grains (less than a third of the target); red meat (approximately 5.5 times the target); dairy foods (approximately 5 times the target); tubers (over 2.5 times the target) and added sugar (close to double of the target). Discussion: To enable comparison with the EAT-Lancet reference diet’s food group level targets, an approach for disaggregating children’s food record data was developed. To achieve a more sustainable diet and comply with the EAT-Lancet targets, the Finnish pre-schoolers would need to consume more plant-based foods i.e. vegetables, legumes and nuts, and whole grains, which should replace the refined grains. The consumption of animal proteins, especially red meat and dairy products, would need to be decreased, as well as the consumption of tubers (mainly potato) and added sugar.

Childhood health is strongly connected with the health later in life. Healthy children are likely to grow up as healthy adults and health in general relates to many positive dimensions of life. However, a shock such as civil war encountered in childhood can have long lasting consequences for later health. The aim of the thesis was to examine how the civil war of 1918 in Finland impacted in the children’s health from four different schools in Helsinki. In addition, the thesis examined were the children’s living environment and previous disease history significant for the health and did there occur differences between the health of girls and boys. The data of the thesis consists of 1 781 elementary school children’s school health records from Kallio, Vallila, Töölö and Tehtaankatu schools in Helsinki, Finland. The data of the thesis is a subsample of historical data which consists of approximately 18 000 Helsinki elementary school student’s health records from the period of 1910-1932. The thesis describes the children’s disease history before the school age and the diseases that occurred during the school years. Height and weight growth curves were formed from the data to visualize the growth patterns of the children over time. In addition, height and weight curves were formed for three different birth cohorts that had gone to school before, during and after the civil war of 1918 to examine the possible differences in growth between the cohorts. Lastly, linear regression analysis was used to analyse were the age, the place of birth, the year of inspection, previous disease history and the school connected with the height and weight growth of the children. The height and weight growth curves showed that the children’s weight and height growth declined in the years 1918-1919. When comparing three birth cohorts, the children who went to school during the civil war of 1918 were shorter than those who went to school before and after the conflict. The most typical diseases that occurred among the children before the school age were measles and whooping cough. Based on the results of the regression analyses the girl’s height growth declined in the year 1919 with 0.82 cm which can indicate that the shock of 1918 became evident in the girl’s height growth in 1919. Having had measles before the school age reduced the height and weight of the boys with 0.86 cm and 0.77 kg. When height’s and weight’s standard deviation scores were regressed with the interaction of boy and measles variables, the connection of the interaction was negative and statistically significant indicating differences between boys and girls: measles was in connected with the boy’s height and weight but not girl’s. Boys who went Töölö and Tehtaankatu schools were taller and heavier than those who went to Kallio and Vallila schools and the results were statistically significant. Among girls, there were no statistically significant differences between students from different schools. The height and weight curves evidently showed that the civil war of 1918 had a negative affect for the children’s growth and therefore also for their health. Results of the regression analyses indicate, that for girl’s height the meaning of the civil war of 1918 was more significant than for boys. For boys, on the other hand, the meaning of having had measles before the school was significant as it reduced their height and weight growth. However, the mechanism behind the measles and reduced growth is ambiguous and there can be various explanations for it. For boys there were also statistically significant differences between students from different schools which reinforces the previous findings from the early 20th century studies concerning the health of the elementary school children. It is not however clear why the differences were only seen among boys and not girls and it is possible that a bigger sample size would have given different results.

Language impairments affect the development of children’s communication skills. Early identification of children that may later face a diagnosis of language disorder is challenging, but early language development is a good indicator of later language skills. The fundamental structures of language are typically mastered by the age of five. Memory skills, which are essential for language development, are also well developed in five-year-old children. Pre-reading skills, such as rapid automatized naming and letter knowledge, develop throughout childhood and have been linked to concurrent language skills. There is, however, little knowledge regarding early development of pre-reading skills in children under the age of five. In this longitudinal study, the relationship between early pre-reading skills at ages 3;6 and 5;0 and language and memory skills at age 5;0 is studied. By increasing the knowledge regarding the development of and the relationship between early pre-reading and language skills more sensitive methods to identify children at risk for language impairment may be developed. In this study, the LUKIVA-test, a method for assessing early pre-reading skills in preschool children, was used. In addition, the language and memory domains of the Five to Fifteen-questionnaire, a parental questionnaire evaluating the development and behavior of 5–15-year-old children, was used. The LUKIVA-test was administered at ages 3;6 and 5;0, the Five to Fifteen-questionnaire filled out when the children were 5;0-years old. The study sample included 40 Finnish-speaking children. This study showed, that age 3;6 and 5;0 LUKIVA-test variables correlated significantly with each other and with age 5;0 language skills. It was also shown, that pre-reading skills at age 3;6, together with gender and maternal education, explain 17% of the variability in language skills at age 5;0. Pre-reading skills in 3;6-year-old children may thus yield important information regarding future language development. In addition, memory skills (sri2 = 43%) markedly added to the explanation of age 5;0 language skills by concurrent pre-reading skills (sri2 = 28%). Pre-reading skills may possibly be used to identify children with weak language skills, whose language development may benefit from additional support.

Suomalaisia vegaaniäitejä ja lapsia ei ole aiemmin tutkittu ravitsemustieteen näkökulmasta. Suomalaisilla suosituksissa (Valtion ravitsemusneuvottelukunta, Sosiaali- ja terveysministeriö) lasten ja äitien vegaaniruokavalioon suhtaudutaan varauksellisesti. Pohjois-Amerikassa mm. American Dietetic Association ja American Academy of Pediatrics sen sijaan pitävät vegaaniruokavaliota ravitsemuksellisesti riittävänä myös raskauden ja imetyksen aikana sekä pikkulapsilla. Suomalainen tutkimustieto on tarpeen mm. laadittaessa uusia suosituksia tulevaisuudessa. Tutkimukseen osallistui 14 perhettä. Vegaaniruokavaliota oli noudatettu 11 raskauden ja imetyksen ajan. Syntymästään saakka vegaanilapsia oli 13. Menetelmänä oli kolmeosainen kyselylomake, jonka tutkittavat palauttivat postitse. Raskaus- ja imetysaikaa tarkastellessani käytin vertailuaineistona niitä seitsemää raskautta, jotka eivät täyttäneet vegaaniruokavalion määritelmää, mutta joiden aikana oli syöty tavanomaista sekaruokavaliota kasvispainotteisemmin. Tutkimukseen osallistuneet olivat koulutettuja ja suurin osa asui kaupungissa. Lapset olivat iältään keskimäärin 1 ½-vuotiaita (vaihteluväli pariviikkoisesta 5-vuotiaaseen). Perheet olivat etsineet itse aktiivisesti tietoa ravitsemusasioista ja tietoa oli saatu myös Vegaaniliitosta. Virallinen terveydenhuolto ei ollut juurikaan pystynyt tarjoamaan tietoa: kahdeksan perhettä oli käynyt ravitsemusterapeutin vastaanotolla, mutta vain yksi ilmoitti saaneensa tietoa sitä kautta. Useimmiten perheen ruokavalio oli herättänyt hämmennystä ja epätietoisuutta terveydenhuollossa. Jotkut olivat kokeneet erittäin negatiivista suhtautumista, etenkin lääkärien taholta, mutta myös myönteisiä kokemuksia oli. Vegaaniäitien keskimääräinen painonnousu raskauden aikana oli normaali ja lapset olivat syntyneet normaalipainoisina. Lasten kasvu oli normaalia. Kaikki äidit olivat huolehtineet D- ja B12-saannista. Myös kaikki lapset saivat ko. vitamiinitäydennyksiä lukuun ottamatta yhtä epäselvää tapausta D-vitamiinin suhteen. Vegaaniäidit imettivät pitkään ja olivat lähempänä imetyssuosituksia kuin suomalaiset yleensä. Tämän tutkimuksen perusteella suomalaisissa vegaaniperheissä ollaan tietoisia D- ja B12-vitamiinien tärkeydestä ja ravitsemusasioista yleensä. Sellaisia ongelmia ei noussut esille, etteikö ruokavaliota voisi suositella
