Impact of Community-Based Nutrition Assessment on Sarcopenia Risk Detection among Older Adults in Nigeria

Abstract

Sarcopenia is an important age-related health concern among older adults in Nigeria and is characterized by progressive loss of skeletal muscle mass, muscle strength, and physical performance. Poor nutritional status, inadequate protein and energy intake, chronic diseases, physical inactivity, and other age-related factors may increase the risk of sarcopenia and contribute to functional decline, falls, disability, loss of independence, and reduced quality of life. However, sarcopenia risk may remain undetected because routine nutritional and functional assessments are not consistently incorporated into community-based healthcare services, while limited awareness, financial constraints, inadequate access to geriatric services, and shortages of trained healthcare personnel may further delay identification. Community-based nutrition assessment provides an opportunity to identify older adults with inadequate nutritional intake and other nutritional risk factors associated with sarcopenia through primary healthcare centres, community outreach programmes, home-based care services, elderly support groups, and other accessible community platforms. Early detection may facilitate nutritional counselling, dietary intervention, physical activity recommendations, clinical evaluation, and referral for further assessment. Against this background, this study investigates the impact of community-based nutrition assessment on sarcopenia risk detection among older adults in Nigeria. The study will be anchored on the Social Ecological Model, Health Belief Model, and Biopsychosocial Model. The Social Ecological Model emphasizes the influence of individual, family, community, socioeconomic, environmental, and healthcare-system factors on nutritional status, physical functioning, and healthy ageing. The Health Belief Model explains how older adults' perceptions of susceptibility to muscle loss, perceived severity of functional decline, perceived benefits of nutritional assessment, perceived barriers, and cues to action may influence participation in community-based nutrition assessment. The Biopsychosocial Model recognizes the interaction of biological, psychological, nutritional, behavioural, and social factors in determining physical functioning and health among older adults. Collectively, these theoretical perspectives provide a suitable framework for explaining how community-based nutrition assessment may influence sarcopenia risk detection among older adults in Nigeria. The study will adopt a quantitative cross-sectional analytical or quasi-experimental research design. The study population will comprise adults aged 60 years and above residing in selected communities across Nigeria. A multistage sampling technique will be used to select states, local government areas, communities, households, primary healthcare centres, elderly support groups, and eligible older adults. Community-based nutrition assessment will be measured using indicators such as availability of nutrition assessment services, assessment coverage, frequency of assessment activities, dietary intake assessment, food-frequency assessment, assessment of protein and energy intake, body mass index, unintentional weight loss, mid-upper arm circumference where appropriate, nutritional risk assessment, assessment of food insecurity, availability of trained nutrition personnel, nutrition education, dietary counselling, and referral arrangements. Sarcopenia risk detection will be assessed using indicators such as low muscle strength, reduced physical performance, reduced muscle mass or muscle quantity where appropriate assessment methods are available, elevated sarcopenia-risk scores, difficulty performing activities of daily living, mobility limitations, history of falls, nutritional risk associated with muscle loss, older adults requiring further clinical or functional assessment, newly identified sarcopenia risk, and referrals for comprehensive geriatric or nutritional evaluation. Data will be collected using structured questionnaires, validated nutritional assessment instruments, dietary assessment tools, anthropometric measurements, functional assessment instruments, handgrip-strength measurements where available, physical-performance assessments, community health records, and referral documentation. Descriptive statistics will be used to summarize participants' demographic characteristics, nutritional status, dietary patterns, physical functioning, and sarcopenia-risk indicators. Inferential statistical techniques, including chi-square tests, correlation analysis, and logistic or multiple regression analysis, will be used to determine the impact of community-based nutrition assessment on sarcopenia risk detection. Where appropriate, sarcopenia-risk detection rates before and after implementation of community-based nutrition assessment activities may be compared to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that community-based nutrition assessment has a significant positive impact on sarcopenia risk detection among older adults in Nigeria. Older adults who participate in systematic community-based nutrition assessment are expected to have a higher likelihood of previously unrecognized nutritional and functional risk factors associated with sarcopenia being identified than older adults without access to such assessment. Routine assessment may facilitate early recognition of inadequate protein and energy intake, unintentional weight loss, nutritional risk, reduced muscle strength, physical-performance limitations, and other factors associated with sarcopenia. Early detection may provide opportunities for dietary counselling, improved protein and energy intake, appropriate physical activity and resistance exercise recommendations, management of underlying health conditions, medication review, and referral for comprehensive geriatric assessment. Bringing nutritional assessment closer to older adults may reduce geographical, financial, mobility, and transportation barriers and may reach individuals who rarely access specialized geriatric or nutritional services. Community-based nutrition education may also improve awareness of the relationship between adequate nutrition, physical activity, muscle health, and healthy ageing. Conversely, limited availability of trained nutrition and geriatric personnel, inadequate assessment equipment, financial constraints, food insecurity, low awareness, mobility limitations, and weak referral and follow-up systems may reduce the effectiveness of community-based nutrition assessment. The study therefore expects accessible and systematically implemented community-based nutrition assessment to contribute significantly to improved detection of sarcopenia risk and early preventive intervention among older adults in Nigeria. The study is expected to contribute to the literature on community-based nutrition assessment, sarcopenia risk detection, older adults' health, geriatric nutrition, muscle health, healthy ageing, nutritional status, physical functioning, community health services, preventive healthcare, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, state ministries of health, primary healthcare centres, nutrition professionals, dietitians, physiotherapists, geriatricians, nurses, community health workers, older adults' organizations, development partners, and policymakers regarding strategies for improving nutritional and functional health among older adults. The study will also provide evidence-based recommendations for expanding community-based nutrition assessment, strengthening nutritional screening at the primary healthcare level, increasing access to trained nutrition and geriatric personnel, improving dietary counselling, promoting adequate protein and energy intake, strengthening physical activity and rehabilitation programmes, improving referral and follow-up systems, and integrating nutrition and sarcopenia-risk assessment into appropriate community-based healthy-ageing and primary healthcare programmes across Nigeria.
