Falls is a major concern in geriatrics due to its high prevalence and various adverse health complications among elderly population. Risk of falls can be reduced by improving nutritional status and increase the level of physical activity. Besides, knowledge regarding risk of falls, nutrition and exercise are important in reducing the risks of falls. Therefore, this study aims to develop, implement and evaluate the effectiveness of a nutritional education and exercise intervention among community dwelling older adults in Selangor.
General Objective: To develop, implement and evaluate the effectiveness of nutrition education and exercise intervention on risk of fall among older person in Selangor. Specific Objectives: * To determine the risk of falls among the older adults. * To determine the dietary intake, anthropometric parameters (body mass index, mid upper arm circumference, calf circumference, body fat percentage and skeletal muscle mass), nutritional status, level of physical activity, functional status, perceived quality of life, risk of sarcopenia, level of knowledge, attitude and practice (KAP) towards falls' risk reduction, nutrition and exercise among the older adults. * To identify the factors determining risk of falls among older adults. * To evaluate the implementation process of the nutrition education and exercise intervention program (attendance and feedback of the program). * To determine the mean differences in risk of falls, dietary intake, anthropometric parameters, nutritional status, physical activity, functional status, perceived quality of life, risk of sarcopenia and knowledge, attitude and practice (KAP) towards falls' risks reduction, nutrition and exercise between intervention and control groups before and after intervention. The proposed study location is in Selangor. This is a randomized wait-list controlled trial for 3 months (12 weeks) among community dwelling older adults in Selangor. A two-stage sampling design will be applied. Firstly, a random sampling will be applied to select two districts from Selangor. This is followed by a purposive sampling to recruit eligible subjects according to inclusion criteria. Subjects will be recruited from free living older adults residing in Selangor through various community settings including including affiliations of National Council of Senior Citizens Organisations Malaysia (NACSCOM), University of Third Age (U3A) and Alzheimer's Disease Foundation Malaysia (ADFM). Subjects will be allocated randomly into 2 groups: Group 1: Intervention group (nutrition education + exercise intervention) Group 2: Control group (no intervention) which total of 100 eligible subjects will be recruited, with 50 subjects are needed in respective groups. This study will use a set of questionnaires to obtain information on personal information, anthropometry data, nutritional status, level of physical activity, functional status, sleep quality, quality of life, risk of falls, risk of sarcopenia and KAP on falls' risk reduction, nutrition and exercise based on appropriate instruments. Assessments will be performed at baseline (week 0), mid-way (week 6) and post-intervention (after week 12).

Mean Changes in Risk of Falls
Risk of falls of the respondents will be determined using Timed Up and Go (TUG) test, Five Times Sit to Stand Test (5XSST) and 30 Second Sit to Stand Test (30CST). For the Timed Up and Go (TUG) test, respondents will be timed while they rise from an arm- chair, walk at a comfortable and safe pace to a line on the floor three meters away (10 feet), turn and walk back to the chair and sit down again. The respondents will walk through the test once before being timed to become familiar with the test.
Time frame: Assessments will be performed at Baseline (Week 0), mid-intervention (Week 6) and Post-Intervention (Week 12)

Mean Changes in Physical Activity Level
The level of physical activity among the respondents will be assessed using the Rapid Assessment of Physical Activity (RAPA), which is a user friendly and validated tool to assess levels of physical activity among older people aged 50 and above. It is made up of nine "Yes" or "No" questions to evaluate the amount and intensity of physical activity of the respondents. It is divided into two components, namely an assessment of aerobic activity from sedentary to moderate and vigorous sports as well as an evaluation of activities that increase strength and flexibility. For the first component on assessment of aerobic activity, respondents are required to choose one question which reflected their level of physical activity with affirmative response. The scores for aerobic activity would be increased if the amount, frequency and intensity of physical activity increased. The scores for these components ranged from 1 to 7 points. Two questions will be developed for the assessment on strength
Time frame: Assessments will be performed at Baseline (Week 0), mid-intervention (Week 6) and Post-Intervention (Week 12)
Mean Changes in Nutritional Status
Nutritional status will be assessed using the short form of the Mini Nutritional Assessment (MNA-SF). The MNA-SF is an effective, easily administered tool designed to identify older adults who have or are at risk of developing malnutrition. This short-standardized questionnaire comprises six questions about food decline, weight loss in the last three months, mobility, actual disease/distress, psychological situation, and additionally anthropometric measures (body mass index or calf circumference). MNA-SF scores will be categorized into three different categories where score below eight indicates malnutrition, 8-11 indicates at risk of malnutrition and 12- 14 represents well-nourished status.
Time frame: Assessments will be performed at Baseline (Week 0), mid-intervention (Week 6) and Post-Intervention (Week 12)
Mean Changes in Functional Status
The well-established Lawton Instrumental Activities of Daily Living (IADL) questionnaire will be used to assess the respondents' ability to perform eight daily activities (i.e. ability to use telephone, shopping, preparing meals, housekeeping, doing laundry, using public transport, taking medications, and handling finances). Presence of 'functional disability' will be defined as having difficulty or needing help in at least one of these 8 items IADL activities, while normal functioning will be defined if one can perform all 8 activities independently.
Time frame: Assessments will be performed at Baseline (Week 0), mid-intervention (Week 6) and Post-Intervention (Week 12)
Mean Changes in Quality of Life
The perceived quality of life of the respondents will be determined using Older Person Quality of Life (OPQOL) Questionnaire. This questionnaire consists of 35 statements with the participant being asked to indicate the extent to which he/she agrees with every single statement by choosing one of five possible options among "strongly disagree", "disagree", "neither agree nor disagree", "agree" and "strongly agree". Each of the five possible answers is given a score of 1 to 5 so that higher scores indicate a better QOL. Thus, the total score ranges from 35 (the worst possible QOL) to 175 (the best possible QOL). The 35 statements of the questionnaire consider the following aspects of QOL: life overall, health (score range 4-20), social relationships and participation, independence, control over life and freedom, home and neighbourhood, psychological and emotional well-being, financial circumstances, leisure, activities and religion.
Time frame: Assessments will be performed at Baseline (Week 0), mid-intervention (Week 6) and Post-Intervention (Week 12)
Mean Changes in Knowledge, Attitude and Practice on Falls' risk reduction, nutrition and exercise Questionnaire
Knowledge, attitude and practice on falls, nutrition and exercise of the respondents will be assessed sing a self-developed questionnaire. This questionnaire consists of 9 domains and 101 items related to KAP on Falls reduction, nutrition and exercise and have been undergone content and face validities. Higher score represent better knowledge, attitude and practice.
Time frame: Assessments will be performed at Baseline (Week 0) and Post-Intervention (Week 12)
Mean Changes in Sleep Quality
Sleeping quality of the respondents will be determined using Pittsburgh Sleep Quality Index (PSQI). PSQI is a structured, self-administered questionnaire that measures retrospective sleep quality and disturbances within the past month. The 7 self-rated questions assess a wide variety of factor related to sleep quality, including estimates of sleep duration and latency. These 7 items are grouped into five component scores, each weighted equally on a 0-3 scale. The five component scores are then summed to yield a sleep quality index score, which has a range of 0-15, with higher scores indicate worse sleep quality. The five components are subjective sleep quality, sleep latency, sleep duration, sleep disturbances and use of sleep medication.
