- BACKGROUND: Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy.OBJECTIVE: The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms) for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on dietary habits, physical activity, body fatness, and glycemia during pregnancy.METHODS: HealthyMoms is a two-arm randomized controlled trial. Women are being recruited at routine visits at the maternity clinics in Linköping, Norrköping and Motala, Sweden. Women are randomized to the control or intervention group (n=150 per group). All women will receive standard care, and women in the intervention group will also receive the HealthyMoms smartphone app.RESULTS: Recruitment of participants to the trial was initiated in October 2017, and 190 women have so far completed the baseline measurement. The baseline measures are estimated to be finalized in December 2019, and the follow-up measures are estimated to be completed in June 2020.CONCLUSIONS: This project will evaluate a novel smartphone app intervention integrated with existing maternity health care. If successful, it has great potential to be implemented nationally in order to promote healthy weight gain and health behaviors during pregnancy.INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/13011.

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.

- The development of accelerometers has revolutionized measurement of physical activity, and they are used to a large extent in research and have started to be implemented into clinical settings. However, achievement of reliable outcomes requires good methodological knowledge and skills by the user. Otherwise, significant measurement errors may occur, interfering with assessment of the physical activity level in the population, group differences, associations with health parameters or effect of treatments. This paper by the Swedish Network for Objective Measurement of Movement (NORM) provides an overview of physical activity measurement including sections of data collection, processing of raw data into useful metrics and statistical analysis. It targets users of accelerometer in research, health care and national surveys.

- 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).

Tidskriftsartikel (refereegranskat)abstract
- 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.

- OBJECTIVES: Reference values are necessary for classifying children, for health screening, and for early prevention as many non-communicable diseases aggravate during growth and development. While physical fitness reference standards are available in children aged 6 and older, such information is lacking in preschool children. Therefore, the purposes of this study were (1) to provide sex-and age-specific physical fitness reference standards for Spanish preschool children; and (2) to study sex differences across this age period and to characterise fitness performance throughout the preschool period.DESIGN: Cross-sectional.METHODS: A total of 3179 preschool children (1678 boys) aged 2.8-6.4 years old from Spain were included in the present study. Physical fitness was measured using the PREFIT battery.RESULTS: Age- and sex-specific percentiles for the physical fitness components are provided. Boys performed better than girls in the cardiorespiratory fitness, muscular strength, and speed-agility tests over the whole preschool period studied and for the different percentiles. In contrast, girls performed slightly better than boys in the balance test. Older children had better performance in all fitness tests than their younger counterparts.CONCLUSIONS: Our study provides age- and sex-specific physical fitness reference standards in preschool children allowing interpretation of fitness assessment. Sexual dimorphism in fitness tests exists already at preschool age, and these differences become larger with age. These findings will help health, sport, and school professionals to identify preschool children with a high/very low fitness level, to examine changes in fitness over time, and to analyse those changes obtained due to intervention effects.

- Purpose The relation between diet and maternal mental health during pregnancy might be relevant to prevent adverse materno-foetal outcomes. This study examined the association of Mediterranean diet (MD) adherence and MD components with mental health during pregnancy. Methods This secondary analysis of the GESTAFIT trial included longitudinal data from 152 pregnant women. Dietary habits were assessed with a food frequency questionnaire, and MD adherence was derived from it using the Mediterranean Food pattern. Psychological ill-being (i.e., negative affect, anxiety, and depression) and well-being (i.e., emotional intelligence, resilience, positive affect) were assessed with the Spanish version of well-established self-reported questionnaires. Cross-sectional (16th gestational week [g.w.]) and longitudinal associations (34th g.w.) between MD and mental health were studied using linear regression models. Results A greater MD adherence was inversely associated with negative affect and anxiety; and positively associated with emotional regulation, resilience and positive affect at the 16th and 34th g.w. (|beta| ranging from 0.179 to 0.325, all p < 0.05). Additionally, a higher intake of whole grain cereals, fruits, vegetables, fish, olive oil and nuts, and a lower intake of red meat and subproducts and sweets were associated with lower negative affect, anxiety, depression and higher emotional regulation, resilience and positive affect throughout gestation (|beta| ranging from 0.168 to 0.415, all p < 0.05). Conclusion A higher intake of whole grain cereals, fruits, vegetables, fish, olive oil and nuts, together with a lower intake of red meat and sweets, resulted in a higher MD adherence, which was associated with a better mental health during pregnancy.

- Purpose: Interpretation of physical activity as energy expenditure requires adjustment for body size. This is usually accomplished by means of the MET system, which assumes a basal metabolic rate (BMR) of 4.184 kJ·kg -1·h-1 and, when the standard calculation is used, that the energy costs of different activities are proportional to BMR. These relationships may be altered by increases in percent total body fat (% TBF), and this paper examines relationships between % TBF and total energy expenditure (TEE) obtained using the standard and a proposed calculation. Methods: Published data regarding body composition, physical activity (heart rate recording), and BMR in 11 American women (before and after weight gain) and in 15 Swedish women (before and during pregnancy) were used to calculate TEE. Reference estimates of TEE were obtained using doubly labeled water. Results: In Swedish women, reference TEE minus standard TEE (MJ·24 h-1) was 1.37 ± 1.29 (P < 0.01) before and 1.03 ± 1.13 (P < 0.05) during pregnancy. For proposed TEE these differences were 0.43 ± 1.63 (P > 0.05) and 0.31 ± 1.28 (P > 0.05) (MJ·24 h-1), respectively. In American women before and after weight gain, reference TEE minus standard TEE (MJ·24 h-1) were 0.38 ± 1.79 (P > 0.05) and 1.39 ± 2.36 (P > 0.05), respectively, whereas the corresponding differences for proposed TEE (MJ·24 h-1) were -0.52 ± 2.20 (P > 0.05) and 0.21 ± 2.36 (P > 0.05), respectively. In Swedish women before pregnancy and American women after weight gain (N = 26, BMI = 18-39), significant (P < 0.001) relationships were found for standard TEE/proposed TEE (y) versus % TBF, (x, r = -0.65) and versus BMI (x, r = -0.70). Conclusions: In individuals with a TBF content typical for contemporary Western women, standard TEE is lower than proposed TEE. This bias increases as the TBF content of subjects increases. The results indicate that proposed TEE is more accurate than standard TEE, but this requires confirmation. Copyright © 2006 by the American College of Sports Medicine.

Maternal body composition in relation to infant birth weight and subcutaneous adipose tissue
- 2006

Tidskriftsartikel (refereegranskat)abstract
- Infant birth weight has increased recently, representing an obstetric and potentially a public health problem since high birth weight involves a risk of obesity later in life. Maternal nutritional status is important for fetal growth and therefore relationships between maternal body weight and composition v. birth weight and infant subcutaneous adipose tissue were investigated in twenty-three healthy women and their newborn infants using multiple and simple linear regression analysis. Furthermore, using previously published data for nineteen infants, it was demonstrated that an anthropometric method could provide useful estimates of the amount of subcutaneous adipose tissue. Birth weight was correlated with the maternal content of total body fat (TBF) both before pregnancy and in gestational week 32 and, together with gestational age at birth, TBF (%) before pregnancy explained 45% of the variation in birth weight. This figure was not increased when gestational gains in weight or TBF were added to the model. Furthermore, in infants, birth weight correlated with the amount of their subcutaneous adipose tissue. Together maternal TBF (%) and amount of subcutaneous adipose tissue in infants explained 61–63% of the variation in birth weight while the amount of infant subcutaneous adipose tissue alone explained only 55%. The maternal TBF content is likely to be important for the recent increase in birth weight. This factor probably causes a general augmentation in fetal growth rather than a specific stimulation of adipose tissue growth.
