Dyslipidemia management in overweight or obese adolescents: A mixed-methods clinical trial of motivational interviewing

The Effect of Motivational Interview-Based Education on Nutrition Exercise Behavior, Sedentary Activity Duration, and Anthropometric Outcomes in Obese Adolescents

PURPOSE

The aim of this study was to examine the effect of motivational interview-based training on nutrition exercise behavior, sedentary behavior duration, and anthropometric outcomes in adolescents.

METHOD

This randomized controlled single-blind experimental study was conducted between January 2021 and March 2023. The research sample consisted of 76 adolescents with obesity (intervention: 38 and control: 38) determined by power analysis. The intervention group received a 6-session motivational interview-based training program. No intervention was applied to the control group. Data were collected using a personal information form, nutrition exercise behavior scale, adolescent sedentary activity questionnaire, and body mass ındex measurement form. Data collection tools were administered to both groups before the intervention, at the last session and at the 3rd month follow-up. In the analysis of the data, chi-square test, independent sample t-test and two-way mixed design ANOVA were used.

RESULTS

There was no statistically significant difference between the pretest nutrition exercise behavior scale, sedentary activity questionnaire, and body mass index z-scores of the intervention and control groups (p > 0.05). After the motivational interview-based education program, nutrition exercise behaviors improved (p: 0.00), sedentary behavior duration and BMI decreased (p: 0.00) in the intervention group. No significant difference was observed in the control group. Nutritional exercise behavior, duration of sedentary behavior and BMI values of the intervention group showed a significant difference compared to the control group (p: 0.00).

CONCLUSION

It was determined that motivational interviewing applied to adolescents with obesity created a positive change on nutritional exercise behavior, sedentary behavior durations, and anthropometric results. It is recommended that nurses should use motivational interviewing in the management of nutrition and exercise behaviors of adolescents with obesity.

Motivational interviewing for the management of child and adolescent obesity: a systematic literature review

BACKGROUND

Among children or adolescents with obesity, 40-70.5% will remain obese as adults according to their paediatric body mass index (BMI). The recommended management involves changes in their nutritional habits (diet, physical activity, and sedentary lifestyle). Motivational interviewing (MI), a patient-centred consultation, has proven its worth in many fields where acting on behaviours is essential.

AIM

To investigate the use and outcomes of MI in the management of children and adolescents who are overweight and obese.

DESIGN & SETTING

A systematic review evaluated MI in the management of children and adolescents who are overweight and obese.

METHOD

PubMed, Web of Science, Cochrane Library, and CISMeF were searched between January 2022 and March 2022 for following terms: 'motivational interviewing', 'overweight or obesity', 'children or adolescent' to identify randomised controlled trials (RCTs). Inclusion criteria were interventions involving MI in children or adolescents who were commonly (polygenically) overweight or obese. Exclusion criteria were: studies before 1991; and articles not written in English or French. The first stage of the selection process was carried out by reading the titles and abstracts. A second stage was carried out by reading the complete studies. A secondary inclusion of articles was carried out following the reading of bibliographic references, mainly from systematic reviews and meta-analyses. The data were summarised in synthetic tables based on the Population, Intervention, Comparison, Outcomes, and Study (PICOS) tool.

RESULTS

From 444 articles the review identified 26 RCTs. Statistically significant results were found for all criteria (anthropometric and behavourial) in both children and adolescents. Quality of life and depression scores were also improved. Parental presence in the interview appeared to be essential for children, whereas for adolescents, the supportive involvement of parents outside of the interviews seemed more appropriate. The frequency and duration of the interventions played a major role in obtaining results, as did the number of people involved, and the diversity of the places where they are taken care of.

CONCLUSION

MI seems promising for children and adolescents with overweight or obesity, within the framework of a comprehensive, multiprofessional, family management, carried out over a long period with regular consultations.

Motivational Interviewing in Pediatric Obesity: A Meta-analysis of the Effects on Behavioral Outcomes

BACKGROUND

Currently, the effects of motivational interviewing (MI) on children's behavioral changes remain obscure.

PURPOSE

This systematic review and meta-analysis examined the effects of MI on children's lifestyle behavioral changes (fruits and vegetables [F/V], dairy, sugary beverages, calories, snacks, fat intake, moderate vigorous physical activity [MVPA], and screen time).

METHODS

Six databases (CINAHL, Cochrane, Embase, PsycINFO, PubMed, and Web of Sciences) from 2005 to 2022 were searched. Thirty-one intervention studies with a comparison group met the criteria. Random-effects models were performed to estimate the pooled effects; exploratory moderation analyses with mixed-effects models were used to explore potential intervention moderators.

RESULTS

The pooled effect size was 0.10 (p = .334) on ↑F/V, 0.02 (p = .724) on ↑dairy, -0.29 (p < .001) on ↓calories, -0.16 (p = .054) on ↓sugary beverages, -0.22 (p = .002) on ↓snacks, -0.20 (p = .044) on ↓fat, 0.22 (p = .001) on ↑MVPA, and -0.06 (p = .176) on ↓screen time. The effects of MIs were moderated by ↑MI sessions regarding ↓snacks (B = -0.04, p = .010). Multicomponent and clinical programs had greater effects on dairy intake than their counterparts (0.09 vs. -0.21, p = .034; 0.12 vs. -0.14, p = .027, respectively). Similarly, interventions with a fidelity check resulted in greater dairy intake than those without a check (0.29 vs. -0.15, p = .014). A few long-term follow-up assessments revealed effects on ↓F/V (-0.18; p = .143, k = 2), ↓dairy (-0.13, p = .399, k = 4), ↓MVPA (-0.04; p = .611, k = 6), and ↑screen time (0.12; p = .242, k = 4).

CONCLUSIONS

Our findings support the short-term effects of MI on improving children's lifestyle behaviors. Additional investigations are needed to better sustain children's long-term behavioral changes.

The application and reporting of motivational interviewing in managing adolescent obesity: A scoping review and stakeholder consultation

Motivational interviewing (MI) is an evidence-based counseling approach that can help individuals make positive behavioral and cognitive changes for managing obesity. We conducted a scoping review to summarize evidence on fidelity and key elements of MI-based interventions for managing adolescent obesity and examine the reporting of these interventions. Ten electronic databases and gray literature were searched systematically and included literature from January 1983 to February 2022, and 26 studies were included. Data on MI features, delivery context, training, and fidelity to treatment were summarized. Fidelity was assessed using an assessment grid with five domains-theory, training, implementation, treatment receipt, and treatment enactment. The last step of the review involved stakeholder consultation with clinician-scientists and researchers with experience in MI and managing adolescent obesity. Thirteen stakeholders were interviewed about our review findings on MI and treatment fidelity. Our analyses revealed that MI-based interventions for managing adolescent obesity had "low treatment fidelity"; no studies had "high treatment fidelity" across all five domains. Fidelity strategies adhered to the most was theory, and treatment enactment was the lowest. Stakeholders mentioned that "low treatment fidelity" may be due to increased time to complete fidelity assessments and increased cost associated with treatment fidelity. These findings have implications for planning, implementing, and evaluating MI-based interventions for managing adolescent obesity.

The effectiveness of nurse-led interventions to prevent childhood and adolescent overweight and obesity: A systematic review of randomised trials

BACKGROUND

Obesity among children and adolescents continues to rise worldwide. Despite the efforts of the healthcare workforce, limited high-quality evidence has been put forward demonstrating effective childhood obesity interventions. The role of nurses as primary actors in childhood obesity prevention has also been underresearched given the size of the workforce and their growing involvement in chronic disease prevention.

AIM

To examine the effectiveness of nurse-led interventions to prevent childhood and adolescent overweight and obesity.

DESIGN

A systematic review of randomised trials.

DATA SOURCES

Medline, CINAHL, EMBASE, Cochrane (CENTRAL), ProQuest Central and SCOPUS were searched from inception to March 2020.

REVIEW METHODS

This review was informed by the Cochrane handbook for systematic reviews of interventions.

RESULTS

Twenty-six publications representing 18 discrete studies were included (nine primary prevention and nine secondary prevention). Nurse-led interventions were conducted in diverse settings, were multifaceted, often involved parents and used education, counselling and motivational interviewing to target behaviour change in children and adolescents' diet and physical activity. Most studies did not determine that nurse-led interventions were more effective than their comparator(s) in preventing childhood and adolescent overweight and obesity.

CONCLUSIONS

Nurse-led interventions to prevent juvenile obesity are feasible but have not yet determined effectiveness. With adequate training, nurses could make better use of existing clinical and situational opportunities to assist in the effort to prevent childhood obesity.

The effects of motivational interviewing on children's body mass index and fat distributions: A systematic review and meta-analysis

Currently, the effects of motivational interviewing (MI) on children's anthropometric changes remain unclear. This systematic review and meta-analysis examined the effects of MI on children's anthropometric changes (body mass index [BMI], waist circumference [WC], and body fat percentage [BF%]). We also assessed potential moderators of MI on children's BMI changes. This systematic review searched five databases (CINAHL, Cochrane, PsycINFO, PubMed, and Web of Sciences) from 2005 to 2020 to evaluate the effects of MI interventions that had a comparison group on children's anthropometric change as outcomes (BMI, WC, or BF%). Thirty-three articles met the inclusion criteria. We performed random-effects models and exploratory moderation analyses with mixed-effects models. The pooled effect size of MI was -0.18 (p = 0.002) on BMI, -0.65 (p < 0.001) on WC, and -0.44 (p = 0.005) on children's BF%. The relationship between MI and BMI changes was significantly moderated by the types of intervener (Q = 9.71, p = 0.021) and the existence of supplemental intervention activities (Q = 9.21, p = 0.002). Other potential moderators included children's age, weight status, intervention setting, and targeted behaviors (eating and/or physical activity). Our findings support the effectiveness of MI interventions on improving children's anthropometric outcomes (i.e., BMI, WC, and BF%).

Nurse-led interventions in the prevention and treatment of overweight and obesity in infants, children and adolescents: A scoping review

BACKGROUND AND OBJECTIVE

Nurses are well-placed in primary care, school and community settings to identify and manage paediatric overweight and obesity. This scoping review examined what types of nurse-led interventions have been undertaken for the prevention, treatment and management of obesity and overweight in infants, children and adolescents.

DESIGN

Scoping review.

DATA SOURCES

CINAHL, Cochrane Library, Embase, MEDLINE, ProQuest Central, ProQuest Dissertations & Theses Global, and Scopus. Searches were undertaken from inception to 2019.

METHODS

Database searches and handsearching were used to identify academic and grey literature, such as scientific reports and university theses and dissertations, on nurse-led interventions undertaken in school, primary health care and community settings. Studies focused on addressing overweight and obesity in children and adolescents, for studies published from 1999 onwards. Studies included focused on experimental and quasi-experimental research that implemented interventions, and described new practice or change in practice.

RESULTS

117 references encompassing 83 studies or programs were selected for inclusion. 16 trials were analysed descriptively, and 67 trials were analysed descriptively and quantitatively. The analysis structured intervention settings and outcomes using the socioecological model, encompassing intrapersonal, interpersonal, community, organisation and policy factors. Studies included were clinically heterogeneous for intervention setting and multicomponent strategies. Education for nutrition, physical activity and behaviour change was the most common strategy used, and nutrition and physical activity knowledge most consistently improved after intervention. Nursing roles focused on education; counselling and behaviour change in primary care; advocacy in school and community environments; and implementing policy in child care settings. Fifty-four studies received financial or resource funding and support to implement the study. On sustainability, seven programs and two research studies were ongoing at time of writing.

CONCLUSIONS

While the clinical heterogeneity of studies makes synthesis of outcomes complex, it demonstrates the breadth of nursing interventions to address paediatric overweight and obesity. Incentives that encourage routine health promotion, upskilling of nurses, and embedding food and nutrition education into the school curricula, are suitable strategies that support nurse-led interventions against paediatric obesity.

Effect of Changes in Patient's Self-management Strategies on Clinical Outcomes: Evidence from a Cohort Study of Patients with Diabetes, Hypertension, and Hyperlipidemia

BACKGROUND

Self-management has become the dominant care model for chronic disease management. This study aimed to investigate the effect of changes in self-management strategies on the clinical outcomes of chronic diseases.

METHODS

Two hundred ninety-seven patients with one or more chronic disease (diabetes, dyslipidemia, or hypertension) were registered and followed in this prospective cohort study. We compared differences in the changes in clinical outcomes from baseline to 6 months according to the improvement of self-management strategies by analysis of covariance.

RESULTS

Diabetic patients with improved self-management strategies showed a significantly greater change in HbA1c levels compared to patients without improvement of self-management strategies (group difference in HbA1c = 0.51%). In hypertensive patients, systolic and diastolic blood pressure (BP) showed a significant decline in the patients with improved self-management strategies (group difference in systolic BP = 6.2 mmHg and in diastolic BP = 5.5 mmHg). Clinical outcomes improved significantly when self-management strategies improved in people with a poor self-management strategy at baseline.

CONCLUSIONS

This study suggests that improvements in self-management strategies are associated with an improvement in clinical outcomes among patients with chronic diseases, especially for those with an initially poor self-management strategy.

Motivational Interviewing to Treat Adolescents With Obesity: A Meta-analysis

CONTEXT

Successful treatment approaches are needed for obesity in adolescents. Motivational interviewing (MI), a counseling approach designed to enhance behavior change, shows promise in promoting healthy lifestyle changes.

OBJECTIVE

Conduct a systematic review of MI for treating overweight and obesity in adolescents and meta-analysis of its effects on anthropometric and cardiometabolic outcomes.

DATA SOURCES

We searched Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, PsychINFO, Web of Science, Cochrane Library, and Google Scholar from January 1997 to April 2018.

STUDY SELECTION

Four authors reviewed titles, abstracts, and full-text articles.

DATA EXTRACTION

Two authors abstracted data and assessed risk of bias and quality of evidence.

RESULTS

Seventeen studies met inclusion criteria; 11 were included in the meta-analysis. There were nonsignificant effects on reducing BMI (mean difference [MD] -0.27; 95% confidence interval -0.98 to 0.44) and BMI percentile (MD -1.07; confidence interval -3.63 to 1.48) and no discernable effects on BMI z score, waist circumference, glucose, triglycerides, cholesterol, or fasting insulin. Optimal information size necessary for detecting statistically significant MDs was not met for any outcome. Qualitative synthesis suggests MI may improve health-related behaviors, especially when added to complementary interventions.

LIMITATIONS

Small sample sizes, overall moderate risk of bias, and short follow-up periods.

CONCLUSIONS

MI alone does not seem effective for treating overweight and obesity in adolescents, but sample size and study dose, delivery, and duration issues complicate interpretation of the results. Larger, longer duration studies may be needed to properly assess MI for weight management in adolescents.
