RESUMEN
BACKGROUND: The electronic medication administration record (eMAR) is an eHealth system that has replaced the traditional paper-based medication administration used in many healthcare settings. Research has highlighted that eHealth technologies can change working methods and professional roles in both expected and unexpected ways. To date, there is sparse research that has explored how nurses and nurse assistants (NA) in home healthcare experience eMAR in relation to their work environment. AIM: The aim was to explore how nurses and nurse assistants experienced their work environment, in terms of job-demand, control, and support in a Swedish home healthcare setting where an electronic medication administration record had been implemented to facilitate delegation of medical administration. METHOD: We took a qualitative approach, where focus groups were used as data collection method. The focus groups included 16 nurses and nine NAs employed in a Swedish municipality where an eMAR had been implemented 6 months before the first focus groups were performed. The analysis adapted the job-demand-control-support model, by condensing the professionals' experiences into the three categories of demand, control, and support, in alignment with the model. RESULTS: NAs experienced high levels of job demand and low levels of job control. The use of the eMAR limited NAs' ability to control their work, in terms of priorities, content, and timing. In contrast, the nurses described demands as high but manageable, and described having a high level of control. Both professions found the eMar supportive. CONCLUSION: Nurses and NAs in home healthcare experienced changes in their work environment regarding demand, control, and support when an eMAR was implemented to facilitate delegation of medical administration. In general, nurses were satisfied with the eMAR. However, NAs felt that the eMAR did not cover all aspects of their daily work. Healthcare organisations should be aware of the changes that digitalisation processes entail in the work environment of nurses and NAs in home healthcare.

BACKGROUND: Sick leave due to stress-related ill-health is increasing and is often caused by occupational imbalance. These types of issues tend to affect both the ability to work and cope with everyday life, as well as the overall experience of health, negatively. There is still little knowledge on how to prepare people and workplaces for the return-to-work process after participation in a work rehabilitation program due to stress and occupational ill-health. Therefore, this study aimed to describe what is needed to achieve a balanced everyday life that includes paid work as experienced by individuals who had participated in a ReDO® intervention due to occupational imbalance and ill-health. METHODS: The concluding notes from 54 informants' medical records were used for qualitative content analysis. The informants had participated in an occupational therapy group intervention to promote occupational health and regain full work capacity. RESULTS: The analysis resulted in one major theme and four categories describing how the informants perceive that they must take control of their everyday life as a whole. By doing so, they need to work with structurization and prioritization, social interaction, boundary setting, and occupational meaningfulness. CONCLUSION: The study indicates a highly relational process, where it is impossible to divide life into private and work, and presupposes balance in everyday life in multiple dimensions. Its contribution includes the formulation of perceived needs in the transition between intervention and return to work and could, through further research, be used to generate a more effective and sustainable return- and rehabilitation models.

RESEARCH QUESTION: Do pregnancies with corpus luteum show different maternal and fetal plasma concentrations of the scavenger proteins haemopexin and α1-microglobulin compared with pregnancies without corpus luteum in preeclampsia? DESIGN: Case-control study of 160 singleton pregnancies: 54 naturally conceived, 50 by IVF after fresh embryo transfer or frozen embryo transfer (FET) in natural cycle (presence of corpus luteum) and 56 after fresh oocyte donation or FET in programmed cycles (absence of corpus luteum). Pregnancies were subclassified into normotensive, preeclampsia and severe preeclampsia cases. Heme-scavenger concentrations were measured by ELISA in maternal and cord plasma collected at delivery. RESULTS: After adjustment, maternal haemopexin was higher in IVF with corpus luteum than in naturally conceived pregnancies in normotensive (Pâ¯=â¯0.038) and preeclampsia (Pâ¯=â¯0.011) populations, and lower in preeclampsia for IVF pregnancies lacking corpus luteum compared with IVF with corpus luteum (Pâ¯=â¯0.002). Maternal α1-microglobulin levels were higher in the absence of corpus luteum only in severe cases of preeclampsia compared with naturally conceived pregnancies (Pâ¯=â¯0.014) and IVF with corpus luteum pregnancies (Pâ¯=â¯0.041). In cord blood, haemopexin was higher in IVF with corpus luteum compared with naturally conceived pregnancies in preeclampsia (Pâ¯=â¯0.039) and α1-microglobulin was higher in the group lacking corpus luteum compared with IVF with corpus luteum in the normotensive population (P < 0.001). CONCLUSIONS: The physiological differences shown for these heme-scavengers between pregnancies after embryo transfer in the presence or absence of corpus luteum support the hypothesis that corpus luteum activity could influence perinatal outcomes. Future research is needed on whether applying potential strategies to develop a corpus luteum might reduce the perinatal complications associated with programmed cycles of IVF.

BACKGROUND: Preeclampsia (PE) is a complex pregnancy syndrome characterised by maternal hypertension and organ damage after 20 weeks of gestation and is associated with an increased risk of cardiovascular disease later in life. Extracellular haemoglobin (Hb) and its metabolites heme and iron are highly toxic molecules and several defence mechanisms have evolved to protect the tissue. OBJECTIVES: We will discuss the roles of free iron, heme, Hb, and the scavenger proteins haemopexin and alpha-1-microglobulin in pregnancies complicated by PE and fetal growth restriction (FGR). CONCLUSION: In PE, oxidative stress causes syncytiotrophoblast (STB) stress and increased shedding of placental STB-derived extracellular vesicles (STBEV). The level in maternal circulation correlates with the severity of hypertension and supports the involvement of STBEVs in causing maternal symptoms in PE. In PE and FGR, iron homeostasis is changed, and iron levels significantly correlate with the severity of the disease. The normal increase in plasma volume taking place during pregnancy is less for PE and FGR and therefore have a different impact on, for example, iron concentration, compared to normal pregnancy. Excess iron promotes ferroptosis is suggested to play a role in trophoblast stress and lipotoxicity. Non-erythroid α-globin regulates vasodilation through the endothelial nitric oxide synthase pathway, and hypoxia-induced α-globin expression in STBs in PE placentas is suggested to contribute to hypertension in PE. Underlying placental pathology in PE with and without FGR might be amplified by iron and heme overload causing oxidative stress and ferroptosis. As the placenta becomes stressed, the release of STBEVs increases and affects the maternal vasculature.

Preeclampsia (PE) is a pregnancy disorder associated with placental dysfunction and elevated fetal hemoglobin (HbF). Early in pregnancy the placenta harbors hematopoietic stem and progenitor cells (HSPCs) and is an extramedullary source of erythropoiesis. However, globin expression is not unique to erythroid cells and can be triggered by hypoxia. To investigate the role of the placenta in increasing globin levels previously reported in PE, flow cytometry, histological and immunostaining and in situ analyses were used on placenta samples and ex vivo explant cultures. Our results indicated that in PE pregnancies, placental HSPC homing and erythropoiesis were not affected. Non-erythroid alpha-globin mRNA and protein, but not gamma-globin, were detected in syncytiotrophoblasts and stroma of PE placenta samples. Similarly, alpha-globin protein and mRNA were upregulated in normal placenta explants cultured in hypoxia. The upregulation was independent of HIF1 and NRF2, the two main candidates of globin transcription in non-erythroid cells. Our study is the first to demonstrate alpha-globin mRNA expression in syncytiotrophoblasts in PE, induced by hypoxia. However, gamma-globin was only expressed in erythrocytes. We conclude that alpha-globin, but not HbF, is expressed in placental syncytiotrophoblasts in PE and may contribute to the pathology of the disease.

Preeclampsia (PE) is a human specific syndrome with unknown etiology causing maternal and fetal morbidities and mortalities. In PE, maternal inflammatory responses are more exaggerated if the fetus is male than female. Other pregnancy complications such as spontaneous abortions are also more common if the fetus is male. Recent transcriptome findings showed an increased expression of CD99 in erythroid cells from male cord blood in PE. The single nucleotide polymorphism (SNP) rs311103, located in a GATA-binding site in a regulatory region on the X/Y chromosomes, governs a coordinated expression of the Xg blood group members CD99 and Xga in hematopoietic cells in a sex-dependent fashion. The rs311103C disrupts the GATA-binding site, resulting in decreased CD99 expression. We aimed to investigate the association between PE and the allele frequency of rs311103 in pregnancies in a fetal sex-dependent fashion. In a case-controlled study, we included 241 pregnant women, i.e., 105 PE cases and 136 normotensive controls. A SNP allelic discrimination analysis was performed on DNA from maternal venous blood and fetal cord blood by qPCR. A statistically significant association was observed between rs311103 allele frequency and PE in mothers carrying male fetuses. Therefore, the rs311103 genotype may play a role in the pathogenesis of PE in a fetal sex-specific manner.

Preeclampsia (PE) has been associated with placental dysfunction, resulting in fetal hypoxia, accelerated erythropoiesis, and increased erythroblast count in the umbilical cord blood (UCB). Although the detailed effects remain unknown, placental dysfunction can also cause inflammation, nutritional, and oxidative stress in the fetus that can affect erythropoiesis. Here, we compared the expression of surface adhesion molecules and the erythroid differentiation capacity of UCB hematopoietic stem/progenitor cells (HSPCs), UCB erythroid profiles along with the transcriptome and proteome of these cells between male and female fetuses from PE and normotensive pregnancies. While no significant differences were observed in UCB HSPC migration/homing and in vitro erythroid colony differentiation, the UCB HSPC transcriptome and the proteomic profile of the in vitro differentiated erythroid cells differed between PE vs. normotensive samples. Accordingly, despite the absence of significant differences in the UCB erythroid populations in male or female fetuses from PE or normotensive pregnancies, transcriptional changes were observed during erythropoiesis, particularly affecting male fetuses. Pathway analysis suggested deregulation in the mammalian target of rapamycin complex 1/AMP-activated protein kinase (mTORC1/AMPK) signaling pathways controlling cell cycle, differentiation, and protein synthesis. These results associate PE with transcriptional and proteomic changes in fetal HSPCs and erythroid cells that may underlie the higher erythroblast count in the UCB in PE.

Renal histologic expression of the podocyte-specific protein, nephrin, but not podocin, is reduced in preeclamptic compared with normotensive pregnancies. We hypothesized that renal expression of podocyte-specific proteins would be reflected in urinary extracellular vesicles (EVs) of podocyte origin and accompanied by increased urinary soluble nephrin levels (nephrinuria) in preeclampsia. We further postulated that podocyte injury and attendant formation of EVs are related mechanistically to cellfree fetal hemoglobin (HbF) in maternal plasma. Our study population included preeclamptic (n=49) and normotensive (n=42) pregnant women recruited at delivery. Plasma measurements included HbF concentrations and concentrations of the endogenous chelators haptoglobin, hemopexin, and α1- microglobulin. We assessed concentrations of urinary EVs containing immunologically detectable podocyte-specific proteins by digital flow cytometry and measured nephrinuria by ELISA. The mechanistic role of HbF in podocyte injury was studied in pregnant rabbits. Compared with urine from women with normotensive pregnancies, urine from women with preeclamptic pregnancies contained a high ratio of podocin-positive to nephrin-positive urinary EVs (podocin+ EVs-to-nephrin+ EVs ratio) and increased nephrinuria, both of which correlated with proteinuria. Plasma levels of hemopexin, which were decreased in women with preeclampsia, negatively correlated with proteinuria, urinary podocin+ EVs-to-nephrin+ EVs ratio, and nephrinuria. Administration of HbF to pregnant rabbits increased the number of urinary EVs of podocyte origin. These findings provide evidence that urinary EVs are reflective of preeclampsia-related altered podocyte protein expression. Furthermore, renal injury in preeclampsia associated with an elevated urinary podocin+ EVs-to-nephrin+ EVs ratio and may be mediated by prolonged exposure to cellfree HbF.

AIMS AND OBJECTIVES: To investigate lung recipients' process of transition from prior the transplantation to one year afterwards, as well as what their main concerns are and how they deal with these concerns. BACKGROUND: During the last three decades, lung transplantation has been established as an effective treatment for patients with end-stage pulmonary disease. Towards the end of the 20th century, the concept of survival expanded to also include improving health-related quality of life (HRQoL). Although many studies have been published regarding lung recipients' HRQoL, aspects of health and everyday life remain understudied. Lung transplantation demands some kind of transition. However, very little is known about this transitional process. DESIGN: A qualitative inductive approach using Grounded Theory (GT) was used. METHODS: A total of ten adult males and five adult females (n = 15) with a mean age of 55 years were included in the study and interviewed one year after transplantation. The open-ended interviews were digitally recorded and transcribed verbatim after each interview. The analysis of the material was performed consistent with Charmaz contructivistic approach of GT. RESULTS: The core category Reconstructing daily occupations summarises a process wherein the generated GT is present through four main categories: Restricting, Regaining, Reorganising and Enriching. The process of reconstructing daily occupations is necessary to regain health. CONCLUSIONS: A trajectory of health transition is evident, starting pretransplant with the lung disease and severe illness and proceeding at least up to one year after the transplantation with experienced health. RELEVANCE TO CLINICAL PRACTICE: The result enables a unique possibility to enhance the lung recipients' striving for everyday life and thereby promote health. There is a need for change in the existing multidisciplinary transplant team to also include an occupational therapist to support and guide the lung recipients in changing their occupational patterns.

BACKGROUND: The working relationship between client and therapist can be important to enhance outcomes from vocational rehabilitation for women with stress-related disorders in primary health care. The aim was to investigate the working relationship, as perceived by clients and therapists in the Redesigning Daily Occupations (ReDO™) program, and its relationships to return to work and satisfaction with the rehabilitation. Another aim was to compare the ReDO™ group and a "care-as-usual" (CAU) group regarding perceptions of the working relationship with the social insurance officer. METHOD: Forty-two ReDO™ clients and 42 matched controls receiving CAU participated. The study included four measurements (baseline, after 16 weeks rehabilitation and follow-ups after 6 and 12 months). 37 + 37 clients completed. Return to work data was obtained from the Social Insurance Offices (SIO), and the working relationship and client satisfaction were assessed by self-report questionnaires. RESULTS: The clients rated the working relationship higher than the therapists (mean rating 101.1 vs. 93.9; p < 0.001). The therapists' rating showed a statistically significant association with return to work at the 12-month follow-up, and the clients' perceptions were statistically significantly related to how they rated satisfaction with the rehabilitation received. The ReDO™ and the CAU groups did not differ regarding how they rated the relationship with the SIO officer (mean ratings 83.9 vs. 77; p = 0.189). The working relationship with the SIO officer was not related to return to work, but an association (rs = 0.70, p < 0.001) to client satisfaction at 16 weeks appeared in the CAU group alone. CONCLUSION: The working relationship as perceived by clients and therapists seemed to be partly separate phenomena, the client perceptions being linked with satisfaction with the rehabilitation and the therapist perceptions with the clients' return to work. The relationship to the SIO officers was of no importance to return to work but was of some significance for satisfaction with the rehabilitation among the CAU clients. Therapists should strive to improve the relationship with clients to whom they feel the relationship is fragile since that might enhance the chances for those clients to return to work.

OBJECTIVE. This study explored factors related to changes in the time parents spent with their children with obesity and associated decreases in children's body mass index (BMI) z-scores after an occupation-focused intervention. METHOD. Parents participated in a 1-yr occupation-focused intervention to promote healthy family lifestyles. Data on 40 parents of 22 children with obesity ages 4-6 yr were collected before and after intervention and analyzed using linear and multiple regression methods. RESULTS. Parents increased time spent with their children by an average of 91 min/day. Parents' finances, perceived satisfaction in daily occupations, low BMI, and mastery at inclusion were associated with increased time spent with their children. Mothers' subjective health and high mastery and fathers' perceived occupational value and education explained 67% of the variance in children's BMI z-scores. CONCLUSION. The results indicate important factors to consider in developing interventions that facilitate occupational engagement and health among children with obesity and their families.
RESUMEN
OBJECTIVE: The aim was to explore any change in parents' time use together with their children, changes in their perceived occupational value, and its relationship to children's body mass index (BMI) over the course of a one-year occupation-focused family intervention. METHOD: The study sample consisted of participants in one arm of a randomized controlled trial, involving mothers and fathers (n = 30) of 17 children aged 4-6 years who were considered obese. Data were collected by time-geographical diaries during the intervention and by measuring the parents' occupational value and the children's BMI before and after the intervention. RESULTS: At the end of the intervention, an increase was shown in the amount of time parents spent together with their children during weekdays (p = .042) and the parents perceived occupational value (p = .013). Children's BMI z-score changed with -0.11 units. CONCLUSION: Collaboration with parents may be useful in interventions aiming at facilitating a normal weight development among children.

BACKGROUND: Predicting severe preeclampsia with need for intensive care is challenging. To better predict high-risk pregnancies to prevent adverse outcomes such as eclampsia is still an unmet need worldwide. In this study we aimed to develop a prediction model for severe outcomes using routine biomarkers and clinical characteristics. METHODS: We used machine learning models based on data from an intensive care cohort with severe preeclampsia (n=41) and a cohort of preeclampsia controls (n=40) with the objective to find patterns for severe disease not detectable with traditional logistic regression models. RESULTS: The best model was generated by including the laboratory parameters aspartate aminotransferase (ASAT), uric acid and body mass index (BMI) with a cross-validation accuracy of 0.88 and an area under the curve (AUC) of 0.91. Our model was internally validated on a test-set where the accuracy was lower, 0.82, with an AUC of 0.85. CONCLUSION: The clinical routine blood parameters ASAT and uric acid as well as BMI, were the parameters most indicative of severe disease. Aspartate aminotransferase reflects liver involvement, uric acid might be involved in several steps of the pathophysiologic process of preeclampsia, and obesity is a well-known risk factor for development of both severe and non-severe preeclampsia likely involving inflammatory pathways..[Figure: see text].

BACKGROUND: People with late effects of polio (LEoP) may need rehabilitation to manage everyday life but knowledge of the benefits of interdisciplinary rehabilitation is limited. OBJECTIVE: To evaluate changes in performance and satisfaction with performance of activities among people with LEoP following interdisciplinary rehabilitation. METHODS: A pre-post retrospective study based on data on 102 participants with LEoP from a rehabilitation clinic. Changes in performance and satisfaction with performance of daily activities before and after interdisciplinary rehabilitation were assessed with the Canadian Occupational Performance Measure (COPM). RESULTS: There were statistically significant increases in the mean performance and mean satisfaction with performance COPM scores from admission to discharge. Twenty-three percent and 19% of the participants, respectively, had improved their performance and satisfaction with performance, 25% and 26% of the participants had no changes, and 19% and 22% of the participants, respectively, rated their performance and satisfaction lower at discharge compared to admission. CONCLUSION: Interdisciplinary rehabilitation can enhance self-rated performance and satisfaction with performance of daily activities among people with LEoP. Future studies of rehabilitation for people with LEoP should use a prospective design and capture the participants' process of change related to their rehabilitation period.

This study explored (a) parents' process of changes and challenges in their patterns of daily activities after the onset of diabetes in their children; and (b) how personal gender relations can restrain or create functional strategies for managing the changes and challenges of illness. Interviews were conducted with 21 mothers and 15 fathers of 23 children with type 1 diabetes 8 to 10 months after onset. Using a constant comparative analysis method, the core category depicts how the illness forced parents to reconstruct their family project with respect to patterns of daily activities and gender structures. The emerging subcategories of reinforced mothering and adjusted fathering illustrate the parents' effort to handle contemporary and contradictory demands. With increased knowledge of the dynamics of gender relations of families in the context of a child's illness, health care professionals can assist in promoting well-being and functional strategies in families when a child is newly diagnosed with diabetes.

BACKGROUND/AIM: Previous research has shown that the Redesigning Daily Occupations programme reduced the degree of sick leave and increased return to work rates among women on sick leave for stress-related disorders when compared with "care as usual". To further investigate the Redesigning Daily Occupations intervention, this study explored changes in the work situation from baseline to a 12-month follow-up in the Redesigning Daily Occupations group compared with the "care as usual" group and analysed any predictors of change. METHODS: A matched-control design was used and 84 women were recruited. Objective (return to work and sick leave) and subjective work outcomes (perceptions of the worker role and the work environment) were explored. Potential predictors were clinical and demographic variables and an anxiety-depression factor. RESULTS: In both groups, large positive effect sizes from baseline to follow-up were found regarding the objective outcomes, a moderate positive effect size was found for perceived work environment, whereas perceived worker role remained unaffected. Previous work rehabilitation predicted objective work outcomes in both groups. Higher education and older age were predictors of subjective outcomes in the Redesigning Daily Occupations group, whereas a more severe anxiety-depression rating was negative for work environment ratings in the "care as usual" group. CONCLUSIONS: Return to work seemed possible without a change in the women's perceptions of the worker role; rather they renegotiated their view of the work environment. The Redesigning Daily Occupations programme was found to be promising, with a positive effect on return to work and sick leave reduction. It seemed more suitable for the higher educated and older women.

INTRODUCTION: Preeclampsia (PE) is a pregnancy-related disorder associated with maternal hypertension and placental dysfunction. A significant micronutrient during pregnancy is iron, which is important in cellular functions. While iron absorption increases in pregnancy, little is known about the exact mechanisms regulating maternal iron levels and transfer through the placenta in normal and complicated pregnancies. METHODS: In this retrospective study, we investigated the regulation of maternal and placental iron availability and storage, in normotensive and pregnancies complicated by early- or late-onset PE. Methods used were analysis of clinical records, ELISA analysis on plasma samples, immunofluorescent and Prussian Blue analysis on placenta biopsies. RESULTS: Focusing on erythroferrone (ERFE) as a new marker and hormonal regulator of iron, our results demonstrated altered maternal ERFE levels in PE. We are the first to report the expression of ERFE in trophoblasts and indicate its lower levels in early-onset PE placentas. These changes were associated with lower placental transferrin receptor 1 (TfR1) in syncytiotrophoblasts in both early- and late-onset PE. In addition, maternal plasma ERFE levels were elevated in both early- and late-onset PE and hepcidin levels reduced in early-onset PE. Unaltered maternal plasma IL-6 levels suggest mechanism other than inflammation being involved in altered iron regulation in PE pregnancy. DISCUSSION: Our data supports a deregulation in maternal iron bioavailability in early- and late-onset PE vs normotensive pregnancies. The exact role of placental ERFE in regulating maternal-placental-fetal iron transport axis requires further investigation.

Preeclampsia (PE) is a pregnancy syndrome characterized by hypertension and organ damage manifesting after 20 gestational weeks. The etiology is of multifactorial origin, where placental stress causes increased levels of placenta-derived extracellular vesicles (STBEVs) in the maternal circulation, shown to cause inflammation, endothelial activation, vasoconstriction, and anti-angiogenic activity. General endothelial dysfunction is believed to be initiated by endothelial insult during pregnancy that alters vascular function resulting in increased arterial stiffness, cardiac dysfunction, and increased risk of cardiovascular disease later in life. We compared the effect of normal and PE derived STBEVs in vitro on vascular contractility of human subcutaneous arteries using wire myography. Cellular structures of exposed vessels were investigated by transmission electron microscopy. We explored strategies to pharmacologically block the effects of the STBEVs on human vessels. The PE STBEVs caused significantly stronger angiotensin II-mediated contractions and extended structural damage to human subcutaneous arteries compared to normal STBEVs. These negative effects could be reduced by blocking vesicle uptake by endothelial cells, using chlorpromazine or specific antibodies towards the LOX-1 receptor. The therapeutic potential of blocking vesicle uptake should be further explored, to reduce the permanent damage caused on the vasculature during PE pregnancy to prevent future cardiovascular risk.

Preeclampsia is a severe pregnancy-related inflammatory disease without an effective treatment. The pathophysiology remains partly unknown. However, an increased inflammatory response and oxidative stress are part of the maternal systemic reaction. Recent data have suggested that dysbiosis of the gut microbiome plays a role in preeclampsia as well as other inflammatory diseases. However, dysbiosis in preeclampsia has not been studied in a Scandinavian population. Furthermore, although the fungal flora may also have anti-inflammatory properties, it has never been studied in preeclampsia. We included 25 preeclamptic and 29 healthy third-trimester women for the ITS and 16S sequencing of fungal and bacterial microbiota, respectively. Calprotectin was measured to assess systemic and intestinal inflammatory responses. The fungal diversity differed with BMI and gestational length, suggesting a link between fungi and the immune changes seen in pregnancy. An LEfSe analysis showed 18 significantly differentially abundant bacterial taxa in PE, including enriched Bacteroidetes and depleted Verrucomicrobia and Syntergistota at the phylum level and depleted Akkermansia at the genus level, suggesting a role in the pathophysiology of PE.

BACKGROUND: As the rate of overweight among children is rising there is a need for evidence-based research that will clarify what the best interventional strategies to normalize weight development are. The overall aim of the Lund Overweight and Obesity Preschool Study (LOOPS) is to evaluate if a family-based intervention, targeting parents of preschool children with overweight and obesity, has a long-term positive effect on weight development of the children. The hypothesis is that preschool children with overweight and obesity, whose parents participate in a one-year intervention, both at completion of the one-year intervention and at long term follow up (2-, 3- and 5-years) will have reduced their BMI-for-age z-score. METHODS/DESIGN: The study is a randomized controlled trial, including overweight (n=160) and obese (n=80) children 4-6-years-old. The intervention is targeting the parents, who get general information about nutrition and exercise recommendations through a website and are invited to participate in a group intervention with the purpose of supporting them to accomplish preferred lifestyle changes, both in the short and long term. To evaluate the effect of various supports, the parents are randomized to different interventions with the main focus of: 1) supporting the parents in limit setting by emphasizing the importance of positive interactions between parents and children and 2) influencing the patterns of daily activities to induce alterations of everyday life that will lead to healthier lifestyle. The primary outcome variable, child BMI-for-age z-score will be measured at referral, inclusion, after 6 months, at the end of intervention and at 2-, 3- and 5-years post intervention. Secondary outcome variables, measured at inclusion and at the end of intervention, are child activity pattern, eating habits and biochemical markers as well as parent BMI, exercise habits, perception of health, experience of parenthood and level of parental stress. DISCUSSION: The LOOPS project will provide valuable information on how to build effective interventions to influence an unhealthy weight development to prevent the negative long-term effects of childhood obesity.
