- “Own doctor” presence in a web-based lifestyle intervention for adults with obesity and hypertension: a randomized controlled trial
2023-03-14 Introduction:Online interventions have long been shown to be an eectivemeans to promote a healthy lifestyle, thereby helping to control body weight and blood pressure figures. Likewise, using video modeling is also considered an eective way to guide patients through behavioral interventions. Nonetheless, to the best of our knowledge, this study is the first to analyze how the presence of patients’ “own doctor” in the audiovisual content of a web-based lifestyle program (“Living Better”) aimed at promoting regular physical exercise and healthy eating behavior, compared with an “unknown doctor,” influences the outcomes of adults with obesity and hypertension. Materials and methods: A total of 132 patients were randomly assigned either to the experimental (n = 70) or control (n = 62) group (“own doctor” or “unknown doctor”, respectively). The body mass index, systolic and diastolic blood pressure, number of antihypertensive drugs used, physical activity level, and quality of life was assessed and compared at baseline and post-intervention (12 weeks). Results: The intention-to-treat analysis showed intragroup significant improvements in both groups in terms of the body mass index (control group: mean dierence −0.3, 95% CI [−0.5, −0.1], p = 0.002; experimental group: −0.4 [−0.6, −0.2], p < 0.001) and systolic blood pressure (control group: −2.3 [−4.4, −0.2], p = 0.029; experimental group: −3.6 [−5.5, −1.6], p< 0.001). In addition, there were also significant improvements in the experimental group for the diastolic blood pressure (−2.5 [−3.7, −1.2], p < 0.001), physical activity (479 [9, 949], p = 0.046), and quality of life (5.2 [2.3, 8.2], p = 0.001). However, when comparing the experimental with the control group, no between-group significant dierences were found in these variables. Conclusions: This study suggests that the presence of patients’ “own doctor” in the audiovisual content of a web-based intervention, aimed at promoting a healthy lifestyle among adults with obesity and hypertension, do not show significant additional benefits over the e cacy of e–counseling.
- How the presence of a doctor known to patients impacts a web-based intervention to promote physical activity and healthy eating behaviour in individuals with an overweight/obesity–hypertension phenotype: a randomised clinical trial
2023-03-27 Background: The ‘Living Better’ web-based programme has shown short- and long-term benefits for body composition and psychological variables in obese patients with hypertension by promoting a healthier lifestyle. To further explore the potential of this programme, in this work we aimed to explore the possible effect of the patient’s ‘own doctor’ appearing in the video content of the Living Better intervention. (2) Methods: A total of 132 patients were randomly assigned either to the experimental (EG, n = 70) or control (CG, n = 62) group (with a doctor the patient knew as ‘their own’ or an ‘unknown doctor’, respectively). The body mass index (BMI), motivation towards physical activity (PA), PA levels, motivation to change one’s eating habits, adherence to the Mediterranean diet, and eating behaviour were all assessed and compared at baseline and post-intervention (12 weeks). (3) Results: The results of this study confirmed the positive effects of the Living Better programme on BMI and external eating style, with significant improvements in these variables in both groups. In addition, in the EG there was higher intrinsic motivation to change eating behaviour (mean difference of 0.9, 95% CI [0.1, 1.6], p = 0.032) and lower amotivation (mean difference of −0.6, 95% CI [−1.2, −0.1], p = 0.027) compared to the CG. (4) Conclusions: This study suggests that the presence of the patients’ own doctor in the audiovisual content of the Living Better intervention did not have significant additional benefits in terms of BMI or external eating style. However, their presence did improve intrinsic motivation and amotivation related to eating habits.
- The impact of a web-based lifestyle educational program ('Living better') reintervention on hypertensive overweight or obese patients
2022-05-27 ‘Living Better’, a self-administered web-based intervention, designed to facilitate lifestyle changes, has already shown positive short- and medium-term health benefits in patients with an obesity–hypertension phenotype. The objectives of this study were: (1) to examine the long-term (3-year) evolution of a group of hypertensive overweight or obese patients who had already followed the ‘Living Better’ program; (2) to analyze the effects of completing this program a second time (reintervention) during the COVID-19 pandemic. A quasi-experimental design was used. We recruited 29 individuals from the 105 who had participated in our first study. We assessed and compared their systolic and diastolic blood pressure (SBP and DBP), body mass index (BMI), eating behavior, and physical activity (PA) level (reported as METs-min/week), at Time 0 (first intervention follow-up), Time 1 (before the reintervention), and Time 2 (post-reintervention). Our results showed significant improvements between Time 1 and Time 2 in SBP (4.7 (8.7 to 0.7); p = 0.017), DBP (3.5 (6.2 to 0.8); p = 0.009), BMI (0.7 (1.0 to 0.4); p < 0.001), emotional eating (2.8 (5.1 to 0.5); p = 0.012), external eating (1.1 (2.1 to 0.1); p = 0.039), and PA (Time 1: 2308 2266; Time 2: 3203 3314; p = 0.030, Z = 2.17). Statistical analysis showed no significant differences in SPB, DBP, BMI, and eating behavior between Time 0 and Time 1 (p > 0.24). Implementation of the ‘Living Better’ program maintained positive long-term (3-year) health benefits in patients with an obesity–hypertension phenotype. Moreover, a reintervention with this program during the COVID-19 pandemic produced significant improvements in blood pressure, BMI, eating behavior, and PA.
- Effects of different strength training intensities on health-related parameters towards engaging in physical activity in elderly
2022-07-06 To assess the effects of a progressive resistance training program at different intensities on health-related quality of life, anxiety, and motivation towards engaging in physical activity among older people. Prospective, municipal multicenters, non-randomized controlled trial. 76 older adults were assigned to: vigorous intensity (n = 19), vigorousmoderate intensity (n = 21), moderate intensity (n = 19), or control group (n = 17). The exercise groups performed six exercises with elastic bands per session, twice a week, for 8 months. Vigorous intensity, vigorous-moderate intensity and moderate intensity group performed 6, 10 and 15 repetitions, respectively. Health-related quality of life was assessed using the 36-Item Short Form Health Survey, trait and state anxiety using the State-Trait Anxiety Inventory, and motivation towards engaging in physical activity using the Behavioural Regulation in Exercise Questionnaire. The moderate intensity group showed a significant increase in the summary of the physical components of health-related quality of life (p = 0.001; ηp2 = 0.158) and a significant decrease in external regulation (p = 0.002; ηp2 = 0.145) and amotivation (p = 0.013; ηp2 = 0.97). In contrast, the vigorous intensity group showed a significant increase in state anxiety (p = 0.004; ηp2 = 0.076) and a significant decrease in introjected regulation (p = 0.018; ηp2 = 0.097). Moderate intensity strength training programs are best suited for older adults because they improve health-related quality of life and decrease less self-determined forms of regulation, all without increasing anxiety states.
- Meaning in life mediates between emotional deregulation and eating disorders psychopathology : a research from the meaning-making model of eating disorders
2021-03-23 Emotional dysregulation, age, gender, and obesity are transdiagnostic risk factors for the development and maintenance of eating disorders (EDs). Previous studies found that patients with ED had less meaning in life than the non-clinical population, and that meaning in life acted as a buffer in the course of ED; however, to the data, there are no studies about the mediator role of meaning in life in association between the emotional dysregulation and the ED psychopathology. Objective: To analyze the mediating role of meaning in life in the relationship between emotional dysregulation and the ED psychopathology in three samples with diverse risk factors for ED. Method: Sample 1, n = 153 undergraduate young women; sample 2, n = 122 participants with obesity; and sample 3, n = 292 participants with ED. Multiple mediation analysis was performed. Results: Sample 1: meaning in life showed a mediation effect between emotional dysregulation and the ED psychopathology (direct effect b = 0.390, p < 0.05) (indirect effect b = 0.227, p < 0.05), body satisfaction (direct effect b = −0.017, p < 0.05) (indirect effect b = −0.013, p < 0.01), and depression symptoms (direct effect b = 1.112, p < 0.001) (indirect effect b = 0.414, p < 0.001); sample 2: meaning in life showed a mediation effect between emotional dysregulation and binge eating and purging behaviors (direct effect b = 0.194, p < 0.01) (indirect effect b = 0.054, p < 0.05) and depression symptoms (direct effect b = 0.357, p < 0.001) (indirect effect b = 0.063, p < 0.05); sample 3: meaning in life showed a mediation effect between emotional dysregulation and the ED psychopathology (direct effect b = 0.884, p < 0.001) (indirect effect b = 0.252, p < 0.007), body satisfaction (direct effect b = −0.033, p < 0.05) (indirect effect b = −0.021, p < 0.001), borderline symptoms (direct effect b = 0.040, p < 0.001) (indirect effect b = 0.025, p < 0.001), and hopelessness (direct effect b = 0.211, p < 0.001) (indirect effect b = 0.087, p < 0.001). Conclusions: These studies suggest the importance of considering meaning in life as a variable in the onset and maintenance of ED.
- The effect of a mindfulness-based therapy on different biomarkers among patients with inflammatory bowel disease : a randomised controlled trial
2020-04-08 Mindfulness-based interventions have shown some efficacy in decreasing stress levels and improving quality of life. However, so far, only a few studies have studied this type of intervention among patients with inflammatory bowel disease and none of them have studied their effects on inflammatory biomarkers. This current study was a two-armed, single-centre, randomised (2:1 ratio) controlled trial used to evaluate the effects of a mindfulness-based intervention (n = 37) compared to standard medical therapy (n = 20) in patients with Crohn’s disease or ulcerative colitis. The mindfulness intervention blended four internet-based therapy modules with four face-to-face support sessions. The outcomes we assessed were faecal calprotectin (primary outcome), C-reactive protein, and cortisol levels measured in hair samples at several timepoints. The between-group analysis highlighted significant decreases in faecal calprotectin and in C-reactive protein levels in the mindfulness-based intervention group compared to the standard medical therapy group at the six-month follow-up (faecal calprotectin: −367, [95% CI: −705, −29], P = 0.03; C-reactive protein: −2.82, [95% CI: −5.70, 0.08], P = 0.05), with moderate to large effect sizes (faecal calprotectin: ηp2 = 0.085; C-reactive protein: ηp2 = 0.066). We concluded that mindfulness-based therapy administered as part of standard clinical practice effectively improves inflammatory biomarkers in patients diagnosed with inflammatory bowel disease.
- Impact of a Web-based exercise and nutritional education intervention in patients who are obese with hypertension : randomized wait-list controlled trial
2020-04-14 Background: Internet-based interventions are a promising strategy for promoting healthy lifestyle behaviors. These have a tremendous potential for delivering electronic health interventions in scalable and cost-effective ways. There is strong evidence that the use of these programs can lead to weight loss and can lower patients’ average blood pressure (BP) levels. So far, few studies have investigated the effects of internet-based programs on patients who are obese with hypertension (HTN). Objective: The aim of this study is to investigate the short- and long-term efficacy, in terms of body composition and BP parameters, of a self-administered internet-based intervention involving different modules and learning techniques aimed at promoting lifestyle changes (both physical activity and healthy eating) in patients who are obese with HTN. Methods: A randomized wait-list controlled trial design was used. We recruited 105 adults with HTN who were overweight or obese and randomly assigned them to either a 3-month internet-based intervention group (n=55) or the wait-list control group (n=50). We assessed BMI (primary outcome), body fat mass (BFM), systolic (S)BP and diastolic (D)BP, blood glucose and insulin levels, physical activity levels, and functional capacity for aerobic exercise at Time 0 (preintervention) and Time 1 (postintervention). All the patients in the wait-list control group subsequently received the intervention, and a secondary within-group analysis, which also included these participants, was conducted at Time 2 (12-month follow-up). Results: A 2-way mixed analysis of covariance showed a significant decrease in BMI, BFM, and blood glucose at 3 months in the internet-based intervention group; the effect size for the BMI and BFM parameters was moderate to large, and there was also a borderline significant trend for DBP and insulin. These results were either maintained or improved upon at Time 2 and showed significant changes for BMI (mean difference −0.4, 95% CI −0.1 to −0.6; P=.005), BFM (mean difference −2.4, 95% CI −1.1 to −3.6; P<.001), DBP (mean difference −1.8, 95% CI −0.2 to −3.3; P=.03), and blood glucose (mean difference −2, 95% CI 0 to −4; P=.04). Conclusions: Implementation of our self-administered internet-based intervention, which involved different learning techniques aimed to promote lifestyle changes, resulted in positive short- and long-term health benefits in patients who are obese with HTN.
- Analysis of the efficacy of an internet-based self-administered intervention (“Living Better”) to promote healthy habits in a population with obesity and hypertension : an exploratory randomized controlled trial
2019-04-03 Introduction: Changes in unhealthy lifestyles are key elements in the prevention and treatment of obesity and hypertension. Internet-based programs offer great potential for the implementation of evidence-based interventions focused on promoting healthy habits. We evaluate the efficacy of an Internet-based self-administered program (“Living Better”) that addresses people diagnosed as being overweight or having type I obesity and hypertension. Methods: The sample was composed of a total of 106 participants (age Mean = 53; 59 males) from a public hospital in Spain, diagnosed as being overweight or having type I obesity and hypertension and randomized into two groups—the intervention group (IG; Internet-based intervention) and the control group (CG; usual medical treatment). The intervention used cognitive-behavioral strategies and psychoeducation to promote healthy habits. Anthropometric data (i.e., Body Mass Index –BMI-, waist circumference, and hip circumference) and lifestyle/psychological data (i.e., quality of life, physical activity, eating styles, motivation, mood, and self-efficacy) were assessed before and after the intervention, and at 6 and 12-month follow-ups. Results: Significant differences were observed between the IG and the CG in anthropometrical variables after intervention (i.e., BMI and waist circumference), external eating style, and anxiety and stress scores (p < 0.05). Follow-up data showed that changes were maintained in BMI, waist and hip circumference, and external eating in the IG. After receiving the Internet-based treatment, the CG also improved its clinical condition. Discussion: This study demonstrates that the Internet is a viable alternative for the delivery and dissemination of interventions focused on promoting healthy habits, and a totally self-administered intervention can produce long-term positive results.
