- BackgroundNational surveys in Sweden demonstrate that the majority of young people do not engage in health promoting behaviours at levels recommended by the Public Health Agency of Sweden. The objective of this study is to estimate the effectiveness of a novel mHealth intervention named LIFE4YOUth, which targets multiple lifestyle behaviours (alcohol, diet, physical activity, and smoking) among high school students in Sweden.MethodsA 2-arm parallel groups single blind randomised controlled trial (1:1) will be employed to estimate the effectiveness of the novel mHealth intervention. Students will be recruited at high schools throughout Sweden, and will be included if they fulfil one of six criteria relating to unhealthy behaviours with respect to alcohol, diet, physical activity and smoking. Eligible participants will be randomised to either receive the novel intervention immediately, or to be placed on a waiting list for 4 months. The intervention consists of a combination of recurring screening, text messages, and an interactive platform which is adaptable to individual preferences. Outcome measures with respect to alcohol, diet, physical activity and smoking will be assessed through questionnaires at 2 and 4 months post randomisation.DiscussionThe findings of this trial could be generalised to a diverse high-school student population as our recruitment encompass a large proportion of schools throughout Sweden with various educational profiles. Furthermore, if effective, the mHealth intervention has good potential to be able to be scaled up and disseminated at high schools nationally.Trial registrationRegistered prospectively on 2020-05-20 in ISRCTN (ISRCTN34468623).

- Background: Clustering of multiple lifestyle risk behaviors has been associated with a greater risk of noncommunicable diseases and mortality than one lifestyle risk behavior or no lifestyle risk behaviors. The National Board of Health and Welfare in Sweden reported in 2018 that it is important to provide additional support to individuals with multiple lifestyle risk behaviors, as risks from these behaviors are multiplicative rather than additive. However, the same report emphasized that there is a lack of knowledge regarding interventions that support changes to unhealthy lifestyle behaviors.Objective: The MoBILE (Mobile health Multiple lifestyle Behavior Interventions across the LifEspan) research program has brought together two Swedish research groups supported by international collaborators. Through this collaboration, we aim to design and evaluate a number of novel and tailored mobile health (mHealth) multiple lifestyle behavior interventions across the life span of different health care populations. In addition, the MoBILE research program will extend ongoing research to include mHealth interventions for migrant pregnant women and children.Methods: Each project within the MoBILE program will focus on a specific group: pregnant women, preschool children, high school and university students, and adults in primary and clinical care. All the projects will follow the same 4 phases: requirements, development, evaluation, and implementation. During the requirements phase, implementers and end users will aid the design of content and functionality of the interventions. In the development phase, findings from the first phase will be synthesized with expert domain knowledge and theoretical constructs to create interventions tailored to the target groups. The third phase, evaluation, will comprise randomized controlled trials conducted to estimate the effects of the interventions on multiple lifestyle risk behaviors (eg, alcohol, nutrition, physical activity, and smoking). The final phase will investigate how the interventions, if found effective, can be disseminated into different health care contexts.Results: The research program commenced in 2019, and the first results will be available in 2020. Projects involving pregnant women, preschool children, and high school and university students will be completed in the first 3 years, with the remaining projects being planned for the program’s final 3 years.Conclusions:The development of evidence-based digital tools is complex, as they should be guided by theoretical frameworks, and requires large interdisciplinary teams with competence in technology, behavioral science, and lifestyle-specific areas. Individual researchers or smaller research groups developing their own tools is not the way forward, as it means reinventing the wheel over and over again. The MoBILE research program therefore aims to join forces and learn from the past 10 years of mHealth research to maximize scientific outcomes, as well as the use of financial resources to expand the growing body of evidence for mHealth lifestyle behavior interventions.

- Aim Physical activity (PA) has traditionally been measured wearing accelerometers on the hip, but they are increasingly being worn on the wrist. We compared hip and wrist accelerometers with regard to their acceptability and any associations between PA and fatness and fitness. Methods This cross-sectional study comprised 103 children aged 8-12 years (62% boys) who participated in the ActiveBrains trial by the University of Granada, Spain, in 2014-2016. The children wore both ActiGraph GT3X+ hip and wrist accelerometers round the clock for 7 days. The acceptability of both placements was evaluated by a questionnaire, while the childrens fat mass index, waist circumference and cardiorespiratory fitness (CRF) were assessed. Results Wearing wrist accelerometers caused less disturbance, mainly because hip accelerometers caused more issues during the night. The measurements from both placements showed that lower PA levels were associated with fatness and that higher PA levels were associated with better CRF. Conclusion Both placements showed consistent results with regard to measuring associations between PA levels and fatness and fitness. However, wearing them on the wrist caused less discomfort at night. Future studies are needed to confirm the best placement for accelerometers during PA studies.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To investigate the associations of muscular strength in adolescence with later disability pension (DP), across different body mass index (BMI) categories and in combination with aerobic fitness.METHOD: This prospective cohort study consisted of males aged 16-19 years, recruited from the Swedish military conscription register between 1969 and 1994. A total of 1 212 503 adolescents met all the inclusion criteria and were therefore included in the analyses. Knee extension, handgrip and elbow flexion strength and aerobic fitness (bicycle ergometer test) were measured during conscription. Causes of DP were retrieved from the Social Insurance Office between years 1971 and 2012 (average follow-up time: 29.6 years).RESULTS: Knee extension strength in adolescence was inversely associated with men's risk of obtaining DP due to all causes (HR 1.40, 95% CI 1.36 to 1.44 for lowest vs highest strength quintile). Thus, muscular weakness was associated with DP. The risk associated with low muscular strength differed between specific causes of DP and the strongest associations were found for psychiatric, nervous system and other causes (HRs between 1.47 and 1.90 for lowest vs highest quintile). Being strong was associated with lower DP risk across BMI categories and being unfit, weak and obese was associated with the highest DP risk (HR 3.70, 95% CI 2.99 to 4.58).CONCLUSION: There was a strong association between muscular weakness and disability. A combination of muscular weakness and low aerobic fitness was an especially important risk factor for disability. This adds weight to call for muscular strength and fitness enhancing exercise for adolescents in all BMI categories.

MINISTOP 2.0 : a smartphone app integrated in primary child health care to promote healthy diet and physical activity behaviors and prevent obesity in preschool-aged children
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- BackgroundChildhood overweight and obesity is currently estimated to affect 39 million children under the age of five worldwide. After the COVID-19 pandemic, further increases have been observed in several countries including Sweden, where an increased incidence was observed in 3- and 4-year-old children, especially in disadvantaged areas. This development emphasizes the urgent need for population-based childhood obesity prevention interventions, and Swedish primary child health care provides an ideal setting for primary preventive efforts during the preschool years. However, thus far, previous child health care-based obesity prevention interventions have demonstrated limited effectiveness. As previous interventions also have been face-to-face delivered and thus resource-demanding; new, and scalable ways of delivering interventions also need to be evaluated. Mobile health or mHealth refers to the use of mobile devices for medical and public health practice and provides opportunity for development and dissemination of digital interventions for various purposes and populations at scale. This thesis reports the results of the MINISTOP 2.0 project, which covers the development and evaluation of the MINISTOP 2.0 digital intervention, from adaptation and translation of the intervention to Somali, Arabic and English (Paper I), to evaluation of real-world effectiveness within the Swedish primary child health care setting (Paper II) followed by exploration of user experiences and implementation aspects (Paper III) and a cost-consequence analysis of the intervention costs (Paper IV). AimThe overall aim of this thesis was to evaluate whether a 6-month parent-oriented mHealth intervention (MINISTOP 2.0 app), embedded in the routine services of Swedish primary child health care, can be used to improve diet and physical activity behaviors, and decrease the prevalence of over-weight and obesity in 2.5-to-3-year-old children. MethodsThe MINISTOP 2.0 project utilized a hybrid type 1 effectiveness-implementation study design to enable simultaneous evaluation and exploration of intervention effectiveness, user experiences and implementation aspects. Paper I: A qualitative exploration of user requirements in an app-based parental support intervention was conducted through three focus group interviews with Somali- (n = 5), Arabic- (n = 4), and Swedish-speaking parents (n = 6), and individual interviews with child health care nurses (n = 15). Data was analyzed using thematic analysis. Paper II: A two-arm parallel randomized controlled trial was conducted at 19 child health care centers located in six Swedish regions. Participating parents (n = 552) were invited during their routine visit at 2.5/3-years at their primary child health care center. All baseline and follow-up procedures were conducted by the nurses. Parents that were randomized to the control group received standard care, while the intervention group received access to the MINISTOP 2.0 app for six months, alongside standard care. Prior to randomization, nurses measured the child’s height and weight for assessment of BMI, and parents answered a questionnaire about their child’s intake of fruit and vegetables, sweet and savory treats, and sweet drinks; time spent in moderate-to-vigorous physical activity (MVPA) and screen time; and parental self-efficacy (PSE) for promoting healthy diet, physical activity, and screen time behaviors. These baseline procedures were then repeated at a 6-month follow-up visit to the child health care center. Paper III: A qualitative exploration of user experiences, acceptability, and feasibility of the MINISTOP 2.0 intervention was conducted through individual interviews with parents (n = 24) with diverse backgrounds, and with child health care nurses (n = 15). Data was analyzed using content analysis. Paper IV: Data on all costs related to the MINISTOP 2.0 intervention, including costs for app and interface upkeep as well as salary costs for introduction and dissemination of the app by nurses, was collected retrospectively. A cost-consequence analysis was then performed to estimate the costs of the intervention. ResultsPaper I: Parents expressed several challenges related to promoting healthy eating behaviors, such as worrying about their child not eating enough, and difficulties balancing different food cultures. There were also requests for the app content to be accessible through alternative modes of delivery (e.g., audio/video) for parents with low literacy. Nurses underlined the importance of supporting parents early with health behavior interventions, and the value of a shared digital platform, available in several languages, to facilitate communication with parents. Paper II: Seventy-nine percent of the participating parents (n = 552) were mothers and 62% had a university degree. Among the children, 24% had two foreign-born parents. Children in the intervention group had lower in-takes of sweet and savory treats (-6.97 g/day; p = 0.001), sweet drinks (-31.52 g/day; p < 0.001), and screen time (-7.00 min/day; p = 0.012) com-pared to the control group at follow-up. Parents in the intervention group also reported higher total PSE (0.91; p = 0.006), PSE for promoting healthy diet behaviors (0.34; p = 0.008) and PSE for promoting healthy physical activity behaviors (0.31; p = 0.009) compared to the control group. For children’s MVPA or BMI z-score, no statistically significant effect was observed between groups. Finally, parents also reported high satisfaction with the app, and 54% reported using the app once a week or more. Paper III: Findings indicated that the app was well accepted and appreciated, as it increased knowledge and awareness around current health behaviors. Furthermore, evidence-based information available in one place and from a trusted source, was highly valued, especially when living in a country with a different culture than your own. The app was also acknowledged as a feasible support tool and a suitable complement to the standard care offered during visits. Finally, due to the accessibility in different languages and the possibility of disseminating the app at scale, both nurses and parents described the app as an appropriate tool for reaching larger populations of parents as well as parents in need of additional support. Paper IV: The total cost for the MINISTOP 2.0 intervention was 437 439 SEK based on the 277 families in the intervention group. The cost for child health care nurses introducing and registering families for the app represented only 9% of the total cost per family, which was considerably lower in comparison to other similar childhood obesity prevention interventions. Also, notably, for upscaling, sharing running costs for the user interface for larger populations of children, would result in much lower total costs per family. ConclusionsOverall, qualitative findings for adapting the intervention highlighted the need for early access to information, as well as the importance of adapting interventions to also be accessible for parents with migrant background and parents with lower literacy. When disseminated through primary child health care, the MINISTOP 2.0 intervention resulted in statistically significant reduced intakes of sweet and savory treats, sweet drinks, and screen time in children (primary outcomes) as well as increased PSE for promoting healthy diet and activity behaviors (secondary outcome). The app was well accepted and perceived as a feasible support tool for parents. Furthermore, accessibility in different languages was also appreciated. Finally, the relatively low salary costs in comparison to face-to-face interventions suggest that the MINISTOP 2.0 app and caregiver interface may be an affordable preventive effort for early promotion of healthy lifestyle behaviors in children when scaled up on a population level. Altogether, the results from the papers in this thesis support the large-scale implementation of the MINISTOP 2.0 app within the Swedish primary child health care setting for promotion of healthy lifestyle behaviours in 2.5-to-3-year-old children.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: With the population-based, prospective Biology, Affect, Stress, Imaging and Cognition (BASIC) cohort, we aim to investigate the biopsychosocial aetiological processes involved in perinatal depression (PND) and to pinpoint its predictors in order to improve early detection.PARTICIPANTS: From September 2009 to November 2018, the BASIC study at Uppsala University Hospital, Sweden, has enrolled 5492 women, in 6478 pregnancies, of which 46.3% first-time pregnancies and with an average age of 31.5 years. After inclusion around gestational week 16-18, participants are followed-up with data collection points around gestational week 32, at childbirth, as well as three times postpartum: after 6 weeks, 6 months and 1 year. At the last follow-up, 70.8% still remain in the cohort.FINDINGS TO DATE: In addition to internet-based surveys with self-report instruments, participants contribute with biological samples, for example, blood samples (maternal and from umbilical cord), biopsies (umbilical cord and placenta) and microbiota samples. A nested case-control subsample also takes part in cognitive and emotional tests, heart rate variability tests and bioimpedance tests. Subprojects have identified various correlates of PND of psychological and obstetric origin in addition to factors of the hypothalamic-pituitary-adrenal axis and immune system.FUTURE PLANS: In parallel with the completion of data collection (final follow-up November 2019), BASIC study data are currently analysed in multiple subprojects. Since 2012, we are conducting an ongoing follow-up study on the participants and their children up to 6 years of age (U-BIRTH). Researchers interested in collaboration may contact Professor Alkistis Skalkidou (corresponding author) with their request to be considered by the BASIC study steering committee.

Tidskriftsartikel (refereegranskat)abstract
- Background: Postpartum depression (PPD) is a devastating disease requiring improvements in diagnosis and prevention. Blood metabolomics identifies biological markers discriminatory between women with and those without antenatal depressive symptoms. Whether this cutting-edge method can be applied to postpartum depressive symptoms merits further investigation. Methods: As a substudy within the Biology, Affect, Stress, Imagine and Cognition Study, 24 women with PPD symptom (PPDS) assessment at 6 weeks postpartum were included. Controls were selected as having a score of ≤ 6 and PPDS cases as ≥12 on the Edinburgh Postnatal Depression Scale. Blood plasma was collected at 10 weeks postpartum and analyzed with gas chromatography-mass spectrometry metabolomics. Results: Variations of metabolomic profiles within the PPDS samples were identified. One cluster showed altered kidney function, whereas the other, a metabolic syndrome profile, both previously associated with depression. Five metabolites (glycerol, threonine, 2-hydroxybutanoic acid, erythritol, and phenylalanine) showed higher abundance among women with PPDSs, indicating perturbations in the serine/threonine and glycerol lipid metabolism, suggesting oxidative stress conditions. Conclusions: Alterations in certain metabolites were associated with depressive pathophysiology postpartum, whereas diversity in PPDS physiologies was revealed. Hence, plasma metabolic profiling could be considered in diagnosis and pathophysiological investigation of PPD toward providing clues for treatment. Future studies require standardization of various subgroups with respect to symptom onset, lifestyle, and comorbidities.

Evaluations of Actiheart, IDEEA and RT3 monitors for estimating activity energy expenditure in free-living women
- 2013
-
Ingår i: Journal of Nutritional Science. - : Cambridge University Press. - 2048-6790. ; 2:e31

Tidskriftsartikel (refereegranskat)abstract
- Activity energy expenditure (AEE) during free-living conditions can be assessed using devices based on different principles. To make proper comparisons of different devices' capacities to assess AEE, they should be evaluated in the same population. Thus, in the present study we evaluated, in the same group of subjects, the ability of three devices to assess AEE in groups and individuals during free-living conditions. In twenty women, AEE was assessed using RT3 (three-axial accelerometry) (AEERT3), Actiheart (a combination of heart rate and accelerometry) (AEEActi) and IDEEA (a multi-accelerometer system) (AEEIDEEA). Reference AEE (AEEref) was assessed using the doubly labelled water method and indirect calorimetry. Average AEEActi was 5760 kJ per 24 h and not significantly different from AEEref (5020 kJ per 24 h). On average, AEERT3 and AEEIDEEA were 2010 and 1750 kJ per 24 h lower than AEEref, respectively (P < 0·001). The limits of agreement (± 2 sd) were 2940 (Actiheart), 1820 (RT3) and 2650 (IDEEA) kJ per 24 h. The variance for AEERT3 was lower than for AEEActi (P = 0·006). The RT3 classified 60 % of the women in the correct activity category while the corresponding value for IDEEA and Actiheart was 30 %. In conclusion, the Actiheart may be useful for groups and the RT3 for individuals while the IDEEA requires further development. The results are likely to be relevant for a large proportion of Western women of reproductive age and demonstrate that the procedure selected to assess physical activity can greatly influence the possibilities to uncover important aspects regarding interactions between physical activity, diet and health.

Development of body composition and its relationship with physical activity in healthy Swedish children : A longitudinal study until 4.5 years of age including evaluation of methods to assess physical activity and energy intake
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Childhood obesity according to the World Health Organization is one of the most serious public health challenges of the 21st century. The proportion of childhood obesity is high both globally and in Sweden. This is of great concern since obese children tend to stay obese in adulthood. In order to develop strategies to prevent early childhood obesity more knowledge is needed regarding factors explaining why children become overweight and obese. Preventive strategies require accurate and easy-to-use methods to assess physical activity in response to energy expenditure as well as energy intake in young children, but such methods are largely lacking or have shown limited accuracy. The aims of this thesis were: 1) to describe the longitudinal development of body composition from 1 week to 4.5 years of age; 2) to study relationships between measures of body composition and the physical activity level (PAL) at 1.5 and 3 years of age; 3) to evaluate if heart rate recording and movement registration using Actiheart can capture variations in total energy expenditure (TEE) and activity energy expenditure (AEE) at 1.5 and 3 years; 4) to evaluate the potential of a 7-day activity diary to assess PAL at 1.5 and 3 years of age; 5) to evaluate a new tool (TECH) using mobile phones for assessing energy intake at 3 years of age.Healthy children were investigated at 1 and 12 weeks (n=44), at 1.5 (n=44), 3 (n=33) and 4.5 (n=26) years of age. Body composition was measured using air-displacement plethysmography at 1 and 12 weeks and at 4.5 years of age. At 1.5 and 3 years, body composition, TEE, PAL and AEE were assessed using the doubly labelled water method and indirect calorimetry. Heart rate and movements were recorded using Actiheart (four days) and physical activities were registered using the 7-day diary. Energy intake was assessed using TECH during one complete 24-hour period.Average percentage of total body fat (TBF) and average fat mass index (FMI) were higher (+3 to +81 %), while fat-free mass index (FFMI) was slightly lower (-2 to -9 %), in children in the study from 12 weeks until 4.5 years of age when compared to corresponding reference values. A relationship between TBF% and PAL was found both at 1.5 and 3 years of age. At 3 years, but not at 1.5 years, this could be explained by a relationship between PAL and FFMI. Actiheart recordings explained a significant but small fraction (8%) of the variation in free-living TEE at 1.5 and 3 years, and in AEE (6 %) at 3 years, above that explained by body composition variables. At 1.5 and 3 years of age, PAL estimated by means of the activity diary using metabolic equivalent (MET) values by Ainsworth et al. was not significantly different from reference PAL, but the accuracy for individuals was low. Average energy intake assessed by TECH was not significantly different from TEE. However, the accuracy for individuals was poor.The results of this thesis suggest that 1) The higher body fatness of the children in the study compared to the corresponding reference values may indicate the presence of a secular trend in body composition development characterized by a high body fatness. 2) Body fatness might counteract physical activity at 1.5 years of age when the capacity to perform physical activity is limited, but not at 3 years of age when such a capacity has been developed. 3) Actiheart recordings explained a significant but small fraction of the variation in TEE at 1.5 and 3 years, and in AEE at 3 years of age, above that explained by body composition variables. 4) The activity diary and TECH produced mean values in agreement with reference PAL and TEE, respectively, but the accuracy for individual children was low.In conclusion, the results of this thesis suggest the presence of a secular trend in body composition development in healthy Swedish children, from infancy up to 4.5 years of age, which is characterized by a high body fatness. Methods to assess physical activity and energy intake at 1.5 and 3 years of age provided some promising results on a group level, although further research is needed to increase the accuracy of these methods in individual children.

Tidskriftsartikel (refereegranskat)abstract
- Background: Meteorological parameters and air pollen count have been associated with affective disorders and suicide. Regarding peripartum depression, the literature is restricted and inconclusive.Methods: This cross-sectional study included women (pregnant, n = 3843; postpartum, n = 3757) who participated in the BASIC (Biology, Affect, Stress, Imaging, and Cognition) study 2010-2015 and the UPPSAT (Uppsala-Athens) study (postpartum, n = 1565) in 2006-2007. Cases were defined according to presence of depressive symptoms during pregnancy (gestational week 32) and 6 weeks postpartum, using the Edinburgh Postnatal Depression Scale (EPDS). Exposure of sunshine, temperature, precipitation, snow coverage, and air pollen counts of durations of 1, 7, and 42 days prior to the outcome were studied for associations with depressive symptoms, using negative binomial regression.Results: Prior to Bonferroni correction, the concentration of mugwort pollen, both one week and six weeks before the EPDS assessment at gestational week 32, was inversely associated with depressive symptoms in pregnancy, both before and after adjustment for season. No associations were found between the exposure to meteorological parameters and pollen and depressive symptoms, at the same day of depressive symptoms' assessment, the previous week, or the six weeks prior to assessment, either during pregnancy or postpartum after Bonferroni correction.Conclusions: There was no evidence that neither short-term nor long-term exposure to meteorological parameters or air pollen counts were associated with self-reported peripartum depressive symptoms in Uppsala, Sweden.
