Visit Experience and Fulfillment of Care Needs in Primary Care Differs for Video Visits Compared to In-person and Chat Visits.

BACKGROUND: There is a lack of research comparing patient experience and to what extent patients' care needs are fulfilled in telemedicine compared to in-person care. OBJECTIVE: To investigate if patient experience and fulfillment of care needs differ between video and chat visits with direct to consumer telemedicine providers compared to in-person visits. DESIGN: Cross-sectional study. PARTICIPANTS: Adults visiting a primary care physician in person or via chat or video in Region Stockholm, Sweden, October 2020-May 2021. MAIN MEASURES: Patient-reported visit experience and fulfillment of care needs. KEY RESULTS: The sample included 3315 patients who had an in-person (1950), video (844), or chat (521) visit. Response rates were 42% for in-person visitors and 41% for telemedicine visitors. Patients were 18-97 years old, mean age of 51 years, and 66% were female. In-person visitors reported the most positive patient experience ("To a very high degree" or "Yes, completely") for being listened to (64%), being treated with care (64%), and feeling trust and confidence in the health care professional (76%). Chat visitors reported the most positive patient experience for being given enough time (61%) and having care needs fulfilled during the care visit (76%). Video visitors had the largest proportion of respondents choosing "To a very low degree" or "No, not at all" for all visit experience measures. There were statistically significant differences in the distribution of visit experiences between in-person, video, and chat visits for all visit experience measures (P < 0.001). CONCLUSIONS: Video visits were associated with a more negative visit experience and lower fulfillment of care needs than in-person visits. Chat visits were associated with a similar patient experience and fulfillment of care needs as in-person visits. Chat visits may be a viable alternative to in-person visits for selected patients.

Effectiveness of a Smartphone App to Promote Physical Activity Among Persons With Type 2 Diabetes: Randomized Controlled Trial.

BACKGROUND: Physical activity is well known to have beneficial effects on glycemic control and to reduce risk factors for cardiovascular disease in persons with type 2 diabetes. Yet, successful implementation of lifestyle interventions targeting physical activity in primary care has shown to be difficult. Smartphone apps may provide useful tools to support physical activity. The DiaCert app was specifically designed for integration into primary care and is an automated mobile health (mHealth) solution promoting daily walking. OBJECTIVE: This study aimed to investigate the effect of a 3-month-long intervention promoting physical activity through the use of the DiaCert app among persons with type 2 diabetes in Sweden. Our primary objective was to assess the effect on moderate to vigorous physical activity (MVPA) at 3 months of follow-up. Our secondary objective was to assess the effect on MVPA at 6 months of follow-up and on BMI, waist circumference, hemoglobin A1c, blood lipids, and blood pressure at 3 and 6 months of follow-up. METHODS: We recruited men and women with type 2 diabetes from 5 primary health care centers and 1 specialized center. Participants were randomized 1:1 to the intervention or control group. The intervention group was administered standard care and access to the DiaCert app at baseline and 3 months onward. The control group received standard care only. Outcomes of objectively measured physical activity using accelerometers, BMI, waist circumference, biomarkers, and blood pressure were assessed at baseline and follow-ups. Linear mixed models were used to assess differences in outcomes between the groups. RESULTS: A total of 181 study participants, 65.7% (119/181) men and 34.3% (62/181) women, were recruited into the study and randomized to the intervention (n=93) or control group (n=88). The participants' mean age and BMI were 60.0 (SD 11.4) years and 30.4 (SD 5.3) kg/m2, respectively. We found no significant effect of the intervention (group by time interaction) on MVPA at either the 3-month (ß=1.51, 95% CI -5.53 to 8.55) or the 6-month (ß=-3.53, 95% CI -10.97 to 3.92) follow-up. We found no effect on any of the secondary outcomes at follow-ups, except for a significant effect on BMI at 6 months (ß=0.52, 95% CI 0.20 to 0.84). However, mean BMI did not differ between the groups at the 6-month follow-up. CONCLUSIONS: We found no evidence that persons with type 2 diabetes being randomized to use an app promoting daily walking increased their levels of MVPA at 3 or 6 months' follow-up compared with controls receiving standard care. The effect of the app on BMI was unclear, and we found nothing to support an effect on secondary outcomes. Further research is needed to determine what type of mHealth intervention could be effective to increase physical activity among persons with type 2 diabetes.

Individual Patient Factors Associated with the Use of Physical or Digital Primary Care in Sweden.

Introduction: Little is known about factors that influence patients' choice to use physical or digital primary care. This study aimed to compare self-rated health, internet habits, and what patients deem important when choosing health care between users of physical and digital primary health care. Methods: We recruited 2,716 adults visiting one of six physical or four digital primary health care providers in Stockholm, Sweden, October 2020 to May 2021. Participants answered a questionnaire with questions about sociodemography, self-rated health, internet habits, and what they considered important when seeking care. We used logistic regression and estimated odds ratios (ORs) for choosing digital care. Results: Digital users considered themselves healthier and used the internet more, compared with physical users (p < 0.001). Competence of health care staff was the most important factor when seeking care to both physical and digital users (90% and 78%, respectively). Patients considering it important to avoid leaving home were more likely to seek digital care (OR 29.55, 95% confidence interval [CI] 12.65-69.06), while patients valuing continuity were more likely to seek physical care (OR 0.25, 95% CI 0.19-0.32). These factors were significant also when adjusting for self-rated health and sociodemographic characteristics. Conclusion: What patients considered important when seeking health care was associated with what type of care they sought. Patient preferences should be considered when planning health care to optimize resource allocation.

A validation study comparing energy and nutrient intake between a web-based food frequency questionnaire and a 4-d dietary record.

OBJECTIVE: Reliable assessments of dietary intake is crucial when examining associations between dietary factors and different outcomes. Today, web-based instead of paper-based food frequency questionnaires (FFQs) are common. A web-based FFQ implies a different experience (including design differences, the possibility only to show relevant questions, and automatic checks for completeness) and may capture dietary intake differently. The aim of this study was to validate a well-used paper-based FFQ transferred to a web-based version against a 4-d dietary record. METHODS: Baseline data from a dietary intervention study comprising women and men with type 2 diabetes were used. Diet was assessed with the web-based FFQ and a 4-d dietary record. Energy intake and energy-adjusted nutrient intakes were assessed and compared using Spearman's rank correlation and Bland-Altman analysis. The analysis included 101 participants. RESULTS: The average energy intake with the FFQ was 2068 kcal, 157 kcal higher than the average from the dietary record. Significant deattenuated correlations were found for intake of energy (r = 0.37; 95% confidence interval [CI],0.19-0.53), carbohydrates (r = 0.85; 95% CI, 0.78-0.89), protein (r = 0.53; 95% CI, 0.38-0.66) and fat (r = 0.59; 95% CI, 0.44-0.70). Significant deattenuated correlations (ranging r = 0.26-0.73) were found for intake of alcohol, whole grain, fiber, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, vitamins A, B12, C, D, and E, folate, iron, potassium, magnesium, and calcium. Bland-Altman analyses showed no clear trends but wide limits of agreement. CONCLUSION: Overall, the web-based FFQ performed well and is similar to the paper-based version. It can be a useful tool for dietary assessments.

Wrist-worn accelerometers: Influence of decisions during data collection and processing: A cross-sectional study.

Background and Aims: Accelerometers collect data in an objective way, however, a number of decisions must be done during data collection, processing and output-interpretation. The influence of those decisions is seldom investigated, reported, or discussed. Herein, we examined the influence of different decisions on the outcomes: daily minutes of moderate-to-vigorous physical activity (MVPA), inactivity and light physical activity (LPA). Methods: In total, 156 participants wore an accelerometer (ActiGraph wGT3X-BT) on their nondominant wrist for 7 days. Data collection was conducted from February 2017 to June 2018. Data was processed using the R-package GGIR and default settings were compared to by-the-literature-suggested options. The output was examined using paired t-tests. Results: When comparing two commonly used MVPA-cut-points, default and Hildebrand et al. we found a marginal difference (0.4 min, 1.0%, p < 0.001) in MVPA/day. When no bout criteria for MVPA/day was applied, MVPA/day was twice as high as bouted MVPA/day. Further, when we changed the epoch-length from 5 to 1 s, statistically significant changes were seen for MVPA/day (-6.6 min, 19%, p < 0.001), inactivity/day (-22 min, 3.0%, p < 0.001) and LPA/day (28 min, 81%, p < 0.001). Conclusion: Decisions made during data processing of wrist-worn accelerometers has an influence on the output and thus, may influence the conclusions drawn. However, there may be situations when these settings are changed. If so, we recommend examining if the variables of interest are affected. We encourage researchers to report decisions made during data collection, processing and output-interpretation, to facilitate comparisons between different studies.

Appetite and its association with mortality in patients with advanced cancer - a Post-hoc Analysis from the Palliative D-study.

BACKGROUND: Loss of appetite is a common nutrition symptom in patients with cancer. Understanding the trajectory of appetite could be of clinical use for prognostication in palliative cancer care. Our primary aim was to explore the association between self-assessed appetite and mortality in patients suffering from advanced cancer. Secondary aims included the relation between fatigue, albumin levels and CRP/albumin ratio and mortality. We also aimed to study potential sex-differences in the associations. METHODS: Post-hoc analyses were performed using data from the Palliative D-study comprising 530 patients with cancer admitted to palliative care. Appetite and fatigue were assessed with the Edmonton Symptom Assessment System (ESAS). Cox proportional hazards models were used to calculate Hazard ratios (HR) with 95% confidence intervals (CI) for exposures of appetite, fatigue, albumin and CRP/albumin ratio, and time from study inclusion to death or censoring. Analyses were also performed stratified by sex. RESULTS: The follow-up time ranged between 7 to 1420 days. Moderate and poor appetite were significantly associated with a higher mortality rate compared to reporting a good appetite; HR 1.44 (95%CI: 1.16-1.79) and HR 1.78 (95%CI: 1.39-2.29), respectively. A higher mortality rate was also seen among participants reporting severe fatigue compared to those reporting no fatigue; HR 1.84 (95%CI:1.43-2.36). Participants with low albumin levels (< 25 g/L) and those in the highest tertile of CRP/albumin ratio, had higher mortality rates, HR 5.35 (95%CI:3.75-7.63) and HR 2.66 (95%CI:212-3.35), compared to participants with high albumin levels (> 36 g/L) and those in lowest tertile of CRP/albumin ratio. These associations were more pronounced in men than in women. CONCLUSION: Poor appetite, severe fatigue, low albumin level and a high CRP/albumin ratio were associated with increased mortality rates among patients with advanced cancer. All these variables might be clinically useful for prognostication in palliative cancer care. TRIAL REGISTRATION: Clinicaltrial.gov. Identifier: NCT03038516;31, January 2017.

The effect of an app-based dietary intervention on diet-related greenhouse gas emissions - results from a randomized controlled trial.

BACKGROUND: Dietary change towards a diet low in greenhouse gas emissions (GHGEs) can reduce climate impact and improve individual-level health. However, there is a lack of understanding if diet interventions can achieve low-GHGE diets. METHODS: A randomized controlled trial was conducted to assess the effects of an app-based intervention. The intervention was designed to improve dietary intake of people with Type 2 diabetes, and was delivered via an app over 12 weeks, with each week covering one diet-related topic. Dietary intake was assessed at baseline and 3-month follow up by a 95-item food frequency questionnaire and linked to GHGE values. A total of n = 93 participants (n = 46 and n = 47 for the intervention and control group, respectively) were included in the analysis. Changes to GHGEs within and between the groups were analysed with inferential statistics. RESULTS: The majority (60%) of participants were male, with a mean age of 63.2 years and body mass index of 30 kg/m2. At baseline, diet-related GHGEs were 4.8 and 4.9 kg CO2-eq/day in the intervention and control group, respectively. At 3-month follow up the corresponding GHGEs were 4.7 and 4.9 kg CO2-eq/day. We found no statistically significant changes to diet-related GHGEs within or between groups, or within food categories, from baseline to 3-month follow up. CONCLUSION: No evidence was found for the effectiveness of the app-based intervention to generate changes to diet-related GHGEs in a population of people with Type 2 diabetes. However, future interventions that target reducing meat consumption specifically may have the potential to result in a reduction of individual-level diet-related GHGEs.

Patients' Perspectives on Dietary Patterns and Eating Behaviors During Weight Regain After Gastric Bypass Surgery.

PURPOSE: Food quality, energy intake, and various eating-related problems have been highlighted as some of the components influencing weight after bariatric surgery. This study aimed to increase our knowledge of patients' perspectives on dietary patterns and eating behaviors during weight regain after bariatric surgery. MATERIALS AND METHODS: We recruited 4 men and 12 women with obesity and the experience of weight regain after bariatric surgery at an obesity clinic in Stockholm, Sweden. Data were collected during 2018-2019. We conducted a qualitative study, carried out individual semi-structured interviews, and analyzed the recorded and transcribed interview data with thematic analysis. RESULTS: Participants had regained 12 to 71% from their lowest weight after gastric bypass surgery performed 3 to 15 years before. They perceived their dietary challenges as overwhelming and had not expected weight management, meal patterns, increasing portion sizes, and appealing energy-dense foods to be problematic after surgery. In addition, difficulties with disordered eating patterns, emotional eating, and increased alcohol intake further contributed to the weight management hurdles. Insufficient nutritional knowledge and lack of support limited participants' ability to avoid weight regain, leading to restrictive eating and dieting without sustained weight loss. CONCLUSION: Eating behavior and dietary factors such as lack of nutritional knowledge, emotional eating, or disorganized meal patterns contribute to difficulties with weight management after gastric bypass surgery. Improved counseling may help patients prepare for possible weight regain and remaining challenges with food and eating. The results highlight the importance of regular medical nutrition therapy after gastric bypass surgery.

Effect of a Smartphone Application on Physical Activity and Weight Loss After Bariatric Surgery-Results from a Randomized Controlled Trial.

PURPOSE: Ways to motivate and support patients in being physically active after bariatric surgery are needed. This trial was aimed at evaluating the effect of using a smartphone application targeting physical activity during 12 weeks on moderate-to-vigorous physical activity (MVPA, primary outcome) and secondary outcomes of inactivity, light physical activity (LPA), body mass index (BMI), and percent total weight loss (%TWL) after bariatric surgery. MATERIALS AND METHODS: Data from a randomized controlled trial comprising 146 patients (79.5% women) undergoing bariatric surgery was analyzed. Mean age and BMI pre-surgery were 40.9 years and 40.5 kg/m2, respectively. Participants were randomized 1:1 to an intervention or a control group. Physical activity and body weight were objectively measured at baseline pre-surgery and post-surgery follow-ups after 6 weeks (weight only), 18 weeks, 6 months, and 1 year. Linear mixed models were fitted to assess longitudinal differences in outcomes between the groups. RESULTS: A significant effect of the intervention (group-by-time interaction 16.2, 95% CI 3.5 to 28.9) was seen for MVPA at 18 weeks; the intervention group had increased their MVPA since baseline, while the control group had decreased their MVPA. The control group had lowered their BMI approximately 1 kg/m2 more than the intervention group at follow-up after 18 weeks and 12 months, yet, mean BMI did not differ between the groups. No intervention effect was seen on inactivity, LPA, or %TWL. CONCLUSION: Our results indicate that use of a smartphone application targeting physical activity may have the potential to promote short-term MVPA post bariatric surgery.

The Swedish Youth with Obesity cohort: Profile of an ongoing prospective study.

OBJECTIVE: As there is a lack of studies on adolescents and young adults with obesity, the Swedish Youth with Obesity cohort was set up to describe the long-term results of medical, as well as surgical, obesity interventions in youth. This article describes the study protocol. METHODS: Since 2018, the study has continuously recruited patients aged between 16 and 25 years who have been admitted for obesity treatment at a specialist obesity clinic in Stockholm, Sweden. Participants provide data from blood tests, questionnaires, and anthropometric measurements. Data are collected longitudinally at enrollment and after 18 months and 3, 4, 5, and 10 years. RESULTS: In the first 500 participants (76% female), the mean age was 21 (SD 3.0) years and the mean BMI was 41.3 (SD 6.1) kg/m2 at enrollment. Almost half of the participants (44.4%) reported that both parents were born outside the Nordic countries. The proportion of participants who smoked at least sometimes was 28.4%. CONCLUSIONS: The longitudinally collected data from the Swedish Youth with Obesity cohort will become a valuable source for answering various research questions regarding long-term results of medical and surgical obesity treatment in adolescents and young adults with obesity.

Prospective study of weight loss and all-cause-, cardiovascular-, and cancer mortality.

Effects of repeated weight changes on mortality are not well established. In this prospective cohort study, we followed 34,346 individuals from 1997 to 2018 for all-cause mortality, and 2016 for cause-specific mortality. At baseline, participants self-reported amount and frequency of prior weight loss. During 20.6 (median) years of follow-up, we identified 5627 deaths; 1783 due to cancer and 1596 due to cardiovascular disease (CVD). We used Cox Proportional Hazards models to estimate multivariable-adjusted Hazard Ratios (HRs) and 95% confidence intervals (CI). Participants with a weight loss > 10 kg had higher rates of all-cause (HR 1.22; 95%CI 1.09-1.36) and CVD mortality (HR 1.27; 95%CI 1.01-1.59) compared to individuals with no weight loss. Men who had lost > 10 kg had higher all-cause (HR 1.55; 95%CI 1.31-1.84) and CVD mortality (HR 1.55; 95%CI 1.11-2.15) compared to men with no weight loss. Participants who had lost ≥ 5 kg three times or more prior to baseline had increased rates of all-cause (HR 1.16; 95%CI 1.03-1.30) and CVD mortality (HR 1.49; 95%CI 1.20-1.85) compared to participants with no weight loss. We found no association between weight loss and cancer mortality. We conclude that previous and repeated weight loss may increase all-cause and CVD mortality, especially in men.

Weight Loss History and Its Association with Self-Esteem and Eating Behaviors in Adolescents and Young Adults with Obesity.

INTRODUCTION: Previous weight loss attempts in young people with obesity may have influenced their beliefs about themselves and contributed to maladaptive eating behaviors. Therefore, we aimed to investigate the association between previous weight loss with self-esteem and different eating behaviors in adolescents and young adults with obesity seeking specialty obesity care. METHODS: We performed a cross-sectional study, where a total of 224 participants with obesity, aged 16-25, self-reported the amount and the frequency of previous weight loss of 5 kg or more. Self-esteem was assessed with Rosenberg's Self-Esteem Scale and eating behavior with the Three-Factor Eating Questionnaire-Revised21. Linear regression was used to analyze associations between the amount of weight loss (no weight loss, 5-10 kg, and >10 kg) and the frequency of weight loss ≥5 kg (0, 1, and ≥2 times) with self-esteem and eating behaviors. RESULTS: We found that both those who had lost 5-10 kg and those who had lost ≥5 kg twice or more, had statistically significantly higher cognitive restraint eating scores ß = 7.03 (95% CI: 0.004-14.05) and ß = 8.32 (95% CI: 1.20-15.43), respectively, compared to those who reported no previous weight loss. No other statistically significant associations were found. CONCLUSION: Previous weight loss in adolescents and young adults with obesity may be associated with a higher cognitive restraint eating behavior. Therefore, assessing weight loss history and eating behavior may be beneficial to better individualize obesity treatment.

Does eating behaviour among adolescents and young adults seeking obesity treatment differ depending on sex, body composition, and parental country of birth?

BACKGROUND: Adolescents and young adults around the world experience high rates of weight gain. The underlying eating behaviours that may lead to overconsumption of energy are complex and can depend on a number of factors. The aim of this study was to explore if eating behaviour among adolescents and young adults referred to specialized obesity treatment differed depending on sex, body composition, and parental country of birth. METHODS: Adolescents and young adults aged 16-25 years, referred for obesity treatment in 2018-2021 were included in the study. Eating behaviour was assessed using the Three Factor Eating Questionnaire, comprising domains of uncontrolled-, emotional- and cognitive restraint eating. Student's t-test was used to compare differences in eating behaviour scores between males and females, and between those having at least one parent born in a Nordic country and those with both parents born outside the Nordic countries. Associations between BMI, waist circumference, and body fat percentage, and eating behaviour as the dependent variable, were examined using linear regression. RESULTS: A total of 463 participants, mean age 21 years and mean BMI 41.3 kg/m2, were included in the analysis. Females scored statistically significantly higher than males on emotional eating (45.8 vs. 35.4, p = 0.002) and cognitive restraint eating (45.4 vs. 39.2, p = 0.009). Participants with at least one parent born in a Nordic country reported a statistically significantly lower score of uncontrolled eating (45.7 vs. 51.3, p = 0.02) compared to participants with both parents born outside the Nordic countries. Further, there were statistically significant inverse associations between cognitive restraint eating scores and BMI (ß=-0.64, 95%CI: -0.97 to -0.31), waist circumference (ß=-0.44, 95%CI: -0.61 to -0.27) and body fat percentage (ß=-0.57, 95%CI: -1.01 to -0.14) in models adjusted for age, sex, smoking, and civil status. CONCLUSION: Our findings suggest that sex and parental country of birth may influence eating behaviours among adolescents and young adults referred for specialist obesity treatment. We also found that cognitive restraint eating decreased with increasing BMI, waist circumference, and body fat percentage. This indicates that there may be an inverse association between the ability to restrain oneself from eating and gaining weight, however, the direction of the association must be investigated further. Increased knowledge about eating behaviours may be valuable in the clinical setting.

Women's Reasons to Seek Bariatric Surgery and Their Expectations on the Surgery Outcome - a Multicenter Study from Five European Countries.

PURPOSE: Understanding patients' reasons for having bariatric surgery and their expectation on surgery outcomes is important to provide the best clinical practice and reduce unrealistic expectations. It is unknown if reasons and expectations differ between countries. We aimed to investigate the reasons for seeking bariatric surgery and expectations of surgical outcomes among patients in five European countries. METHODS: In total, 250 women accepted for bariatric surgery were recruited: 50 women each from Finland, Germany, Norway, Sweden, and the Netherlands. Participants ranked 14 reasons for seeking surgery, and reported the three primary reasons. They also reported expectations on weight loss and impact of surgery vs. lifestyle on weight loss outcomes. RESULTS: Mean age and body mass index were 42.9 ± 11.5 years and 45.1 ± 6.2 kg/m2, respectively. Weight loss and improved co-morbidity were ranked as the most important reasons. Participants expected to lose between 70.8 and 94.3% of their excessive weight. The expected impact of surgery as a driver of weight loss was higher in Germany and the Netherlands compared to in Finland, Norway, and Sweden where participants expected lifestyle changes to also have an impact. CONCLUSION: Weight loss and improved co-morbidities were the main reasons for undergoing bariatric surgery. Expectations on weight loss were generally very high, but expectations of surgery vs. lifestyle as the main driver of weight loss differed between countries. While some patients understand the importance of lifestyle change and maintenance of a healthy lifestyle after surgery in order to obtain a successful weight loss, other may need additional counselling.

Weight Loss in Advanced Cancer: Sex Differences in Health-Related Quality of Life and Body Image.

Weight maintenance is a priority in cancer care, but weight loss is common and a serious concern. This study explores if there are sex differences in the perception of weight loss and its association to health-related quality of life (HRQoL) and body image. Cancer patients admitted to Advanced Medical Home Care were recruited to answer a questionnaire, including characteristics, the HRQoL-questionnaire RAND-36, and a short form of the Body Image Scale. Linear regression analyses stratified by sex and adjusted for age were performed to examine associations between percent weight loss and separate domains of HRQoL and body image score in men and women separately. In total, 99 participants were enrolled, of which 80 had lost weight since diagnosis. In men, an inverse association between weight loss and the HRQoL-domain physical functioning, ß = -1.34 (95%CI: -2.44, -0.24), and a positive association with body image distress, ß = 0.22 (95%CI: 0.07, 0.37), were found. In women, weight loss was associated with improvement in the HRQoL-domain role limitations due to physical health, ß = 2.02 (95%CI: 0.63, 3.41). Following a cancer diagnosis, men appear to experience weight loss more negatively than women do. Recognizing different perceptions of weight loss may be of importance in clinical practice.

Screen time and physical activity in children and adolescents aged 10-15 years.

BACKGROUND: Previous research studies have demonstrated a relationship between low levels of physical activity and high amounts of screen time in children and adolescents. However, this is usually based on self-reported data. Therefore, the aim of this cross-sectional study was to investigate the association between objectively measured smartphone screen time and physical activity among children and adolescents aged 10-15 years. METHODS: During seven consecutive days, we objectively assessed smartphone screen time, using the SCRIIN smartphone application, and physical activity, using the SCRIIN activity tracker, in children and adolescents recruited from two schools in Stockholm County, Sweden. Moreover, the children/adolescents and their parents responded to a questionnaire, obtaining among other things: self-reported screen time, physical activity, sleep and health-related quality of life. RESULTS: A total of 121 children and adolescents (mean age: 12.1 ± 1.5) were included in the study. Objectively measured smartphone screen time was 161.2 ± 81.1 min/day. Mean physical activity, measured with the SCRIIN activity tracker, was 32.6 ± 16.5 active min/day. Minutes of screen time and physical activity did not differ between the children and adolescents from the two schools, despite located in different socioeconomic areas. Further, we found no association between smartphone screen time and physical activity. However, girls aged 14-15 years, had more smartphone screen time (p<0.01) and were significantly more physically active (p<0.01) than girls aged 10-12 years. In addition, boys reported more than five times more time spent on computer and video games than girls did. CONCLUSION: Smartphone screen time was not associated with physical activity level among children and adolescents aged 10-15 years.

Digital Support for Healthier Eating Habits Among Patients With Type 2 Diabetes: Protocol for a Randomized Clinical Trial Within Primary Care (HAPPY Trial).

BACKGROUND: Despite the large impact that dietary habits have in the management of diabetes, few tools for supporting healthy eating habits are available for persons with diabetes. OBJECTIVE: The aim of this randomized clinical trial is to evaluate the effect of a 12-week, mobile health (mHealth), app-based intervention promoting healthy eating habits among patients with type 2 diabetes. METHODS: The HAPPY (Healthy eating using APP technologY) trial is a randomized clinical trial with two arms aiming to include 200 patients, 18 years of age or older, with type 2 diabetes. Both women and men are eligible for inclusion. Study participants are randomized 1:1 to an intervention group, where they are instructed to use a smartphone app promoting healthy eating, or to a control group, where they receive standard primary care only, for a period of 12 weeks. Each week a new topic (eg, vegetable intake) is introduced via the app. After an introduction text, the user is given a topic-related activity to perform (eg, eat one additional serving of vegetables per day during that week). The app records daily progress and sends automatic reminders or feedback to the user. Dietary intake, body composition, clinical variables, and biomarkers are measured at baseline and at 3- and 6-month follow-ups. An extensive web-based questionnaire comprising several validated questionnaires assessing a number of lifestyle factors is distributed via email at baseline and at 3-, 6-, and 12-month follow-ups; lifestyle factors include, for example, sleep, physical activity, eating behavior, and health-related quality of life. The effect of the intervention on dietary intake (primary outcome) and on glycated hemoglobin and blood lipid levels, body composition, blood pressure, other lifestyle factors, and overall health (secondary outcomes) will be assessed. RESULTS: Data collection is ongoing. Recruitment of participants started in January 2019. Findings from the study are expected to be published by the end of 2021. CONCLUSIONS: Technology development provides new ways to promote and support long-term adherence to healthier eating habits. mHealth-based approaches allow for real-time interaction and the delivery of an intervention at any time. Further, focusing on overall diet allows the user to apply new knowledge to current eating patterns, creating an individualized approach. In this study, we evaluate the effect of using a new smartphone app promoting healthy eating habits on dietary intake, clinical markers, and lifestyle factors among patients with type 2 diabetes.

Is leisure time sitting associated with mortality rates among men diagnosed with localized prostate cancer?

OBJECTIVE: Being physically active postdiagnosis has been associated with lower rates of prostate cancer progression and mortality, but studies investigating postdiagnostic time spent sitting are lacking. We aim to study the association between leisure time sitting after a prostate cancer diagnosis and overall and prostate cancer-specific mortality. METHODS: Data from 4595 men in Sweden, diagnosed with localized prostate cancer between 1997-2002 and followed-up until the end of 2012, were analyzed. Time spent sitting during leisure time postdiagnosis was categorized into <2, 2-3, 3-4, and >4 h/day. Multivariable-adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CI) of postdiagnosis leisure time sitting and a joint variable of sitting time and exercise, and time to overall or prostate cancer-specific death. RESULTS: The results showed no significant associations between postdiagnostic leisure time sitting and overall or prostate cancer-specific mortality rates. When the joint effect of both sitting and exercise time was considered, borderline significantly lower mortality rates for overall and prostate cancer-specific mortality were seen among participants that sat the least and exercised the most compared to the reference category with participants sitting the most and exercising least (HR: 0.75; 95% CI: 0.56-1.00 and HR: 0.61; 95% CI: 0.36-1.05, respectively). CONCLUSIONS: No significant association between leisure time sitting and mortality rates among men diagnosed with localized prostate cancer was seen. This study does not support an association between leisure time sitting per se; however, being physically active may have beneficial effects on survival among men diagnosed with localized prostate cancer.

Women's Satisfaction with and Reasons to Seek Bariatric Surgery-a Prospective Study in Sweden with 1-Year Follow-up.

BACKGROUND/OBJECTIVES: Despite profound weight loss after bariatric surgery, some patients are dissatisfied with the results. Pre-surgery expectations, as well as post-surgery items of satisfaction, need to be clarified. The main objective in this study was to investigate the primary reasons to seek bariatric surgery and assess items of satisfaction 1-year post-surgery. SUBJECTS/METHODS: This is a prospective cohort study of women (n = 50) undergoing bariatric surgery in Stockholm, Sweden. Pre-surgery assessment included reasons to seek surgery, expected weight loss, co-morbidities, and quality of life. Post-surgery assessment included items of satisfaction, weight loss, co-morbidities, and quality of life. In total, two women did not undergo surgery, and 40 women had complete data from all pre- and post-surgery assessments. RESULTS: Mean change in body mass index (BMI) pre- and post-surgery was - 12.9 (3.7) kg/m2. At 1-year post-surgery, the mean percent of excess weight loss (%EWL) was 86.9 (26.3). Pre-surgery, the most reported reason to seek surgery was "weight loss" (47.9%), while the most reported item of satisfaction post-surgery was "improved self-esteem" (55.6%). Satisfaction with the result 1-year post-surgery was associated with the extent of %EWL. Satisfied patients (n = 32) had a mean %EWL of 94.6 (22.9), while those not satisfied (n = 8) had a mean %EWL of 59.9 (17.6). CONCLUSIONS: The primary reason to seek bariatric surgery was weight loss. However, despite profound weight loss, improved self-esteem was the item of most satisfaction post-surgery. Our findings may be useful in the clinical setting when informing patients pre-surgery about what to expect as well as when meeting a patient post-surgery to discuss results.
