Adherence to resistance training and hypocaloric diet among persons near retirement age - A secondary data analysis of three randomized controlled trials.

OBJECTIVES: Adherence to lifestyle interventions is crucial for the treatment of obesity. However, there is little research about adherence to lifestyle interventions in persons around retirement age. The objectives of this study are (1) to identify factors associated with the adherence to resistance training and a hypocaloric diet and (2) to describe the association between adherence and changes in body composition outcome parameters. DESIGN: This secondary data analysis included three randomized controlled trials. SETTING & PARTICIPANTS: The inclusion criteria of the participants were an age of 55-75 years, a BMI ≥ 25 kg/m2 and receiving both a hypocaloric diet and resistance training. All participants were residing in the community. MEASUREMENTS: Adherence to hypocaloric diet was measured through the mean dietary intake on the basis of a 3-day dietary record. If the participant consumed at least 600 kcal less than the individual caloric requirements, they were considered adherent. Adherence to resistance training was achieved if ≥67% of the recommended training sessions were attended over the course of the study periods. RESULTS: 232 participants were included, 47.0% female, mean age 64.0 (±5.5) years. 80.2% adhered to resistance training and 51.3% adhered to a hypocaloric diet. Older age (Beta 0.41; 95% CI 0.05, 0.78; p = 0.028) and male sex (Beta 7.7; 95% CI 3.6, 11; p < 0.001) were associated with higher resistance training adherence. A higher BMI at baseline (Beta 6.4; 95% CI 3.6, 9.2; p < 0.001) and male sex (Beta 65; 95% CI 41, 88; p < 0.001) were associated with higher adherence to hypocaloric diet. CONCLUSION: We identified several associated factors (sex, age and BMI at baseline) that should be considered to promote adherence in future lifestyle intervention studies in persons around retirement age. We recommend including behavior change techniques in lifestyle interventions and consider sex-specific interventions to improve the adherence of women.

Identification of factors associated with sarcopenic obesity development: Literature review and expert panel voting.

Sarcopenic obesity (SO) is defined as the combination of excess fat mass (obesity) and low skeletal muscle mass and function (sarcopenia). The identification and classification of factors related to SO would favor better prevention and diagnosis. The present article aimed to (i) define a list of factors related with SO based on literature analysis, (ii) identify clinical conditions linked with SO development from literature search and (iii) evaluate their relevance and the potential research gaps by consulting an expert panel. From 4746 articles screened, 240 articles were selected for extraction of the factors associated with SO. Factors were classified according to their frequency in the literature. Clinical conditions were also recorded. Then, they were evaluated by a panel of expert for evaluation of their relevance in SO development. Experts also suggested additional factors. Thirty-nine unique factors were extracted from the papers and additional eleven factors suggested by a panel of experts in the SO field. The frequency in the literature showed insulin resistance, dyslipidemia, lack of exercise training, inflammation and hypertension as the most frequent factors associated with SO whereas experts ranked low spontaneous physical activity, protein and energy intakes, low exercise training and aging as the most important. Although literature and expert panel presented some differences, this first list of associated factors could help to identify patients at risk of SO. Further work is needed to confirm the contribution of factors associated with SO among the population overtime or in randomized controlled trials to demonstrate causality.

Development and evaluation of a Massive Open Online Course (MOOC) for healthcare professionals on malnutrition in older adults.

BACKGROUND: Education about malnutrition in older adults is often lacking in the curricula of healthcare professionals. Massive open online courses (MOOCs) are an innovative form of education that can potentially improve the knowledge of healthcare professionals. OBJECTIVES: (1) to describe the development of a MOOC on malnutrition in older adults and (2) to evaluate the MOOC on the basis of knowledge gained. DESIGN: The MOOC was developed by following a structured approach. For the evaluation of the MOOC, a cross-sectional descriptive study was conducted. PARTICIPANTS: Overall, 1288 nurses, dietitians, medical doctors and other healthcare professionals participated in the evaluation study. METHODS: After performing a comprehensive literature review, two dietitians specialised in geriatrics developed a summary of potentially important content of the MOOC. Nine European malnutrition experts from different professional areas were then asked to contribute their expertise. The specific MOOC content was developed based on the recent literature and evidence-based guidelines. For the evaluation of the MOOC, a questionnaire with 41 questions was developed. Results were analysed using descriptive statistics and chi-square tests. RESULTS: The final MOOC consists of five modules with 15 learning videos and supplementary material. The percentage of persons with good malnutrition knowledge increased from 76.1 % to 89.9 % (p < 0.001), while the percentage of persons with fair or little malnutrition knowledge decreased (p < 0.001). The course significantly improved the participants' knowledge of specific malnutrition topics, namely, methods and instruments to determine the nutritional status of older people, interventions to improve oral intake, medical nutrition and multidisciplinary cooperation (p < 0.001). Overall, 91.5 % of the participants rated the quality of the course as very good or good. CONCLUSION: MOOCs may be an effective tool that can be used to improve knowledge in healthcare professionals. This provides new opportunities for successful multidisciplinary malnutrition management in clinical practice.

Dysphagia in Hospitalized Older Patients: Associated Factors and Nutritional Interventions.

OBJECTIVES: To (1) assess the association between dysphagia and malnutrition as well as other related factors and (2) investigate the nutritional interventions that are initiated in dysphagic older patients. DESIGN: Cross-sectional, multi-center point prevalence measurement. SETTING: 53 Austrian hospitals. PARTICIPANTS: 3174 hospitalized patients, 65 years or older. MEASUREMENTS: A standardized and tested questionnaire was used for the data collection, which was based on both inspections of the patients and information documented in the patient chart. Medical diagnoses were assessed by referring to the International Classification of Diseases. Dysphagia was measured by asking the patient a dichotomous question. Several other data points were collected including: gender, age, number of diseases, malnutrition, care dependency scale (CDS) score and dependency during activities of daily living (ADL). To investigate the associations between dysphagia and malnutrition and other associated factors, cross tabulation, chi-squared test, t-test and Mann-Whitney U test were used. RESULTS: The prevalence of dysphagia among these patients was 7.6%. Dysphagia and malnutrition were significantly associated (< 0.001). Patients with dysphagia had statistically significant lower BMI values (p = 0.01), more medical diagnoses (p = 0.003) and were more care dependent (p < 0.001) than patients who did not suffer from dysphagia. The frequency of underlying respiratory diseases, dementia, nervous system disorders and cerebrovascular accidents also differed significantly between dysphagic and non-dysphagic patients. The following nutritional interventions were most frequently initiated in patients with dysphagia: provision of texture-modified food/fluid (32.2%), referral to a dietitian (31.4%), provision of an energy- and/or protein-enriched diet (27.3%), monitoring of nutritional intake (21.5%), enteral nutrition (19.4%) and provision of energy-enriched snacks (15.7%). 24% of patients received no nutritional interventions. CONCLUSION: This study demonstrates that a very strong association exists between dysphagia and malnutrition as well as high levels of care dependency and dependency in activities of daily living. Nearly one-quarter of the patients did not receive any nutritional intervention. Therefore, a potential for the improvement of nutritional therapy in older dysphagic hospitalized patients still exists.
