Dietary Behaviour Change Intervention Among Older People With Sarcopenic Obesity

August 18, 2022 updated by: Dr. Justina Liu Yat Wa, The Hong Kong Polytechnic University

Dietary Behaviour Change Intervention on Managing Sarcopenic Obesity in Community-dwelling Older People: a Feasibility and Pilot Study

The aim of this study is to evaluate the feasibility and preliminary effects of dietary behavior change intervention on the management of sarcopenic obesity (SO) among older people in the community.

The feasibility and preliminary effects of the intervention will be tested using a two-armed pilot randomized controlled trial among older people (N=60) with SO in the community in Nanjing, China. Finally, 10 participants will be invited to join a semi-structured interview to explore their perceptions about the whole intervention process.

It is hypothesized that the experimental group will have a greater improvement in the body composition, muscle strength and physical function compared to the control group after receiving the 15-week dietary behavior change intervention.

Detailed Description

The pilot study is a single-blind, two-arm randomized controlled trial. A total of 60 subjects (60 years old or more) are planned to be recruited. The subjects will be randomly divided into 2 groups witht a ratio of 1:1. One is the experimental group and the other is the control group.

The experimental group will receive 15 weeks of dietary intervention, including 6 face-to-face meetings and weekly telephone call. Each meeting lasts for 1 hour. The participants in the experimental group are required to control of calorie intake (decrease energy intake by 12%) and increase protein intake (1.2-1.5 g/body weight kg/day), and take dietary diary.

The control group will not receive any dietary interventions. They will only receive regular contacts with a similar frequency as the experimental group. The content of the conversations will not involve any topics related to SO.

After the intervention, 10-15 people from the experimental group will be randomly selected to receive semi-structured individual interview, which will last around 1 hour. The researcher plan to understand their feelings about participating in the study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Sham Comparator: Control group
The control group will be asked to continue their own daily routes. One research assistant, who will not be involved in other procedures of the study, will contact with the participants to talk about different issues except the SO related topic. The frequency of face-to-face meetings and telephone calls will be similar to the experimental group. The issues talked in the control group could be as follows but not limited: a) normal social communication topics such as greetings, recent living conditions, news in the past week; b) health consultations asked by the participants; c) avoid to mention dietary or exercise related information. An appointment of post-test will be made in the last time telephone call.
The control group will not be required any dietary changes. The investigator will contact with the control group with the same frequency and numbers of experimental group. But the chat topic will not be related to sarcopenic obesity or dietary guidance.
Experimental: Experimental group
The experimental group will be required to adhere to a diet consisting of a 12% reduction in calorie and a 1.2-1.5 g/kg body weight/day intake of protein. The participants will receive 6 times face-to-face meetings (on week 1, 2, 3, 4, 8 and 12) and weekly telephone call. Each face-to-face meetings will last for around 1 hour, during which the reseacher will help to establish the participants' intention for dietary behavior change, then help transform the intention into detailed plan, and help monitor the execution of the plan continuously.
The intervention consists of dietary guidance and behaviour change techniques, which will last for 15 weeks. The experimental group will be required to adhere to a diet consisting of a 12% reduction in calorie and a 1.2-1.5 g/kg body weight/day intake of protein. The participants will receive the dietary behaviour change guidance in 6 times face-to-face meetings and weekly telephone calls. They will also be asked to take daily food diary.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes of muscle strength
Time Frame: Change from baseline to 1 week after the programme
Handgrip strength (kg) will be measured by using the jamar dynamometer.
Change from baseline to 1 week after the programme
Changes of physical function
Time Frame: Change from baseline to 1 week after the programme
The Short Physical Performance Battery (SPPB) scale will be used to measure physical function, which is a well-established tool for monitoring function in older people, which contains three kinds of assessments: stand for 10 seconds with feet in 3 different positions, 3-meter or 4-meter walking speed test, and time to rise from a chair for five times. The scores of SPPB range from 0 (worst performance) to 12 (best performance).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mini Nutritional Assessment (MNA) Short-form
Time Frame: Change from baseline to 1 week after the programme
Participants' nutritional status will be assessed through the Mini Nutritional Assessment (MNA). It is a simple and quick tool for assessing older people who are malnourished or at risk of malnutrition. The MNA Short-form contains 6 items. Questions are weighted, 2-3 ponits per item. Scores are categoried as 0-7 (malnourished), 8-11 (at risk of malnutrition), 12-14 (normal nutritional status).
Change from baseline to 1 week after the programme
Nutrition Self-efficacy Scale
Time Frame: Change from baseline to 1 week after the programme
The nutrition self-efficacy scale is one part of the Health-Specific Self-efficacy Scale which was developed by Ralf Schwarzer and Britta Renner. The nutritional self-efficacy scale is a 5-item scale, and each item is rated on 4-point likert scale from 1= very uncertain, 2=rather uncertain, 3=rather certain, 4=very certain. Higher score means higher self-efficacy.
Change from baseline to 1 week after the programme
Dietary quality index-International
Time Frame: Change from baseline to 1 week after the programme
The DQI-I will be used to estimate the dietary quality of participants. It is a well-used questionnaire without being affected by culture.
Change from baseline to 1 week after the programme
Short Form Health Survey (SF-36)
Time Frame: Change from baseline to 1 week after the programme
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health, which is always used to assess people's health status and quality of life. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability.
Change from baseline to 1 week after the programme
International Physical Activity Questionnaire Short-form (IPAQ-SF)
Time Frame: Change from baseline to 1 week after the programme
The International Physical Activity Questionnaires Short-form (IPAQ-SF) contains (4 generic items, which is used to evaluate the vigorous activities that participants did in the last 7 days. MET minutes represent the amount of energy expended carrying out physical activity. The higher score means engaging in higher level of physical activity.
Change from baseline to 1 week after the programme
