Prevalence of disabilities and non-communicable diseases in an elderly population in the Telangana state, India: a population-based cross-sectional study

Mapping gaps and exploring impairment and disability prevalence in South Asian (SAARC) countries: a scoping review

Despite the considerable health and economic burden of disability in the South Asian (SA) region, there is limited evidence of impairments and disabilities prevalence and the need for Assistive Technologies (ATs). This scoping review aims to synthesise the evidence of the impairments and disabilities in SA countries. This review followed Arksey and O'Malley's methodological framework. EBSCOhost, EMBASE, PubMed, and Web of Science databases were searched for original research articles from SA countries. In this study, impairment and disability refer to functional limitations restricting individuals from performing activities, including visual, hearing, speaking, cognitive, mobility, and self-care difficulties. The review included full-text, English-language articles addressing any impairment and disability, without restrictions on publication date. This review identified 105 articles distributed over the six impairment and disability domains: visual, hearing, mobility, self-care, speaking, and cognitive. Most evidence originated from India (50.5%) and focused on visual impairments (53.3%). The review identified that heterogeneity in methodologies, case identification definitions, and study settings contributed to variations in prevalence estimation and restricted the comparability within and across countries. Besides, the uneven distribution of studies across countries suggests varying inclinations of countries toward specific impairment and disability domains. The review identified variations in prevalence due to differences in methodologies, definitions, and contexts. The review also identified the uneven distribution of studies, limited evidence on ATs, reliance on self-reported data, and lack of nationally representative research. Future research should use standardised case identification and evidence-based approaches to enhance comparability and minimise response biases.

Prevalence of diabetes and disability among older adults in West Bengal and India: A comparative analysis

BACKGROUND

Aging is a heterogeneous process, and older adults are at greater risk of experiencing physical and functional health challenges. This study examines the comparative prevalence of diabetes-related disability among older adults in West Bengal and India.

METHODS

Data were drawn from the first wave of the Longitudinal Aging Study in India (2017-18), comprising 72,250 individuals aged 45 years and above, including 3933 respondents from West Bengal. A multistage stratified sampling method was used. Functional disability was assessed using six Activities of Daily Living (ADL) and seven Instrumental Activities of Daily Living (IADL). Logistic regression was used to assess the association between diabetes and disability, and the Blinder-Oaxaca decomposition technique was applied to identify the contribution of various factors to the observed differences.

RESULTS

The prevalence of ADL and IADL difficulties among older adults with diabetes was 24.1 % in West Bengal and 18.9 % at the national level. The risk of disability among diabetic elderly was significantly higher in West Bengal [OR = 6.20 (3.74-10.26) for ADL; OR = 6.71 (4.69-9.61) for IADL] compared to India [OR = 3.92 (1.10-14.03) for ADL; OR = 3.91 (1.17-13.12) for IADL]. Decomposition analysis showed that comorbidity factors accounted for 37 % of the ADL/IADL disability gap between West Bengal and India.

CONCLUSION

Nearly one-fourth of older adults with diabetes in West Bengal experience ADL limitations. There is urgent need to enhance healthcare services for individuals in West Bengal who are face higher levels of diabetes and disability.

Disability and its sociodemographic correlates among older people in Nepal: evidence from the 2022 Nepal Demographic Health Survey

BACKGROUND

Older people are more vulnerable and have a higher risk of having a disability. There are very few studies on disability among older people in Nepal. To fill this knowledge and research gap, this study examines the prevalence and analyzes sociodemographic correlates of disability among older people in Nepal.

METHODS

The 2022 Nepal Demographic and Health Survey data was used for this study. The study included 3014 older people aged 60 years and above. The Washington Group Short Set Questions were used to measure disability. Disability was categorized as 'with disability' and 'without disability'. Descriptive statistics were used to assess the prevalence of disability while multivariate logistic regression was used as inferential statistics to analyze sociodemographic correlates of disability.

RESULTS

The results show that more than a quarter (27%) of older people had disabilities. The prevalence of disability was higher among older people aged 80 years and above (54%), females (31%), no education (31%), widowed (40%), residing in Karnali province (39%), and those who belonged to poor household wealth (31%). This pattern was consistent in both older males and females. Older people aged 70-79 or 80 years and above, those who had no education or primary education and who were widowed, were more likely to have a disability. Older people from rich household wealth and from Koshi, Madhesh, Bagmati, Gandaki, Lumbini and Sudurpashchim provinces were less likely to have a disability.

CONCLUSIONS

The burden of disability among older people in Nepal is considerable. Therefore, there is a need for health interventions targeting the identified groups at risk of disability to improve the well-being of older people.

Task-sharing with community health workers to treat hypertension: a scoping review

Many studies have implemented and evaluated task-sharing interventions with community health workers (CHWs) to manage hypertension. To identify gaps in research, we conducted a scoping review. We searched original articles published in PubMed and EMBASE between 2010 and 2022 and found 122 articles meeting our inclusion criteria. Only seven articles were from low-income countries (LICs), most of which were qualitative studies or mixed methods studies. In the identified 122 articles, CHWs often performed health education (61.3%) and measured blood pressure (60.4%). Whereas CHWs carried out pharmacological treatment in only three studies. Participant homes (75.0%) were the most common setting for receiving interventions. Our study identified specific needs for future research, specifically, studies in LICs that are experimental in design and that collect relevant qualitative information, and studies in which CHWs do advanced task. In addition, publications of CHW studies should provide a more comprehensive list of intervention features.

Understanding the association of disability with multimorbidity, and healthcare utilization in India's older adult population: insights from cross-sectional evidence of SAGE-2

Background

Like other low-and middle-income countries, India is undergoing a demographic and epidemiologic shift that has led to a significant rise in the burden of non-communicable diseases (NCDs). Evidence suggests that chronic illnesses and disability are linked but limited studies have explored the association between disability and multimorbidity (simultaneous presence of two or more chronic conditions). Since the magnitude of multimorbidity is becoming a norm, it is prudent to understand the association between these two. We aimed to estimate the association between disability and multimorbidity and assess their healthcare utilization among older adults in India using a nationally representative data.

Methods

We employed data from the second round of World Health Organization's Study on Global AGEing and adult health (SAGE) conducted in 2015. SAGE is a nation-wide survey conducted among a representative sample of older adults aged ≥50 years, a total of 7,118 participants aged ≥50 years were included in the analysis. The main outcome of interest was disability for which we used WHODAS 2.0 scoring scale which ranges from 0 to 100. Descriptive statistics such as frequency and proportion were used to report the characteristics of study population, and prevalence. We performed the univariable followed by multiple ordinal logistic regression to assess the association between disability and multimorbidity, reported as adjusted odds ratio (AOR) with 95% confidence interval (CI) and p-value. Healthcare utilization was presented as frequency and proportion.

Results

The overall prevalence of disability was found to be 89.0% (95% CI: 88.3-89.8) while that of multimorbidity was 39.7% (95% CI: 35.6-37.8). Most of the participants had moderate followed by mild disability. Hypertension (32.7%) was found to be the most prevalent chronic condition followed by cataract (21.3%). The chances of having disability among multimorbid individuals was AOR: 1.40 (95% CI: 1.13-1.75). Participants having disability and multimorbidity mostly visited private sector followed by public healthcare facilities.

Conclusion

We observed that nine out of every 10 individuals had some kind of disability in India. We observed multimorbidity to be associated with disability that signifies the need for including disabilities as a part of NCD program as these factors could be bi-directional. Longitudinal studies for disability will be helpful to better understand and address the growing needs of these individuals.

Beyond Numbers: Decoding the Gendered Tapestry of Non-Communicable Diseases in India

INTRODUCTION

Non-communicable diseases (NCDs) represent a major global health challenge, particularly in low- and middle-income countries like India, with significant gender disparities in mortality and disease burden. This study aims to investigate these disparities, using data from national health surveys, to inform gender-specific public health strategies and align with global health goals.

METHODOLOGY

The study uses data from the Longitudinal Aging Study in India (LASI) and National Family Health Surveys (NFHS-4 and NFHS-5).

RESULT

The results from the Longitudinal Ageing Study in India (LASI) and National Family Health Surveys (NFHS-4 and NFHS-5) indicate significant demographic and health-related variations among 65,562 participants. Key findings show gender disparities in lifestyle habits such as alcohol and tobacco use, and differences in health outcomes across age, education, and socioeconomic status. Notably, an increase in NCD prevalence, particularly hypertension and diabetes, was observed from NFHS-4 to NFHS-5, highlighting evolving health challenges in India.

CONCLUSIONS

The study emphasizes the importance of gender in the prevalence and management of non-communicable diseases (NCDs) in India, advocating for public health strategies that address gender differences, socio-economic factors, and urban-rural disparities to achieve health equity.

Cross-sectional study of prevalence, causes and trends in visual impairment in Nirmal District, Telangana, India: Nirmal Eye Evaluation for Trends study

OBJECTIVE

To determine the prevalence, causes and risk factors associated with visual impairment (VI) in the Nirmal district of Telangana, India, using extended Rapid Assessment of Visual Impairment (RAVI) methodology.

DESIGN

Cross-sectional study.

SETTING

Community setting.

PARTICIPANTS

Participants aged ≥16 years were enumerated from 90 randomly selected clusters and 4629/5400 (85.7%) participants were examined. Presenting visual acuity (VA) was assessed using a Snellen chart with E optotypes at a 6 m distance. Near vision was assessed binocularly using an N notation chart with tumbling E optotypes at a 40 cm distance. An anterior segment examination done followed by distance direct ophthalmoscopy at 50 cm. Non-mydriatic fundus images were obtained. VI was defined as presenting VA worse than 6/12 in the better eye. The prevalence of VI in the current study was compared with a RAVI study conducted in 2014 to assess the trends in VI among those aged ≥40 years.

PRIMARY OUTCOME

Prevalence, causes and risk factors for VI.

RESULTS

Among those examined, 55% were women, 53% had at least school-level education, 2.3% self-reported diabetes and 8.7% self-reported hypertension. The prevalence of VI was 8.81% (95% CI 8.01% to 9.67%). Overall, uncorrected refractive errors (49.5%) were the leading cause of VI, followed by cataracts (40.2%) and posterior segment diseases (4.9%). Among those aged ≥40 years, the prevalence of VI declined by 19.3% compared with the 2014 baseline study (from 20.2% to 16.3%; p<0.01).

CONCLUSION

The extended RAVI study conducted in the Nirmal district showed a considerable decline in the prevalence of VI. Targeted interventions are needed to provide adequate eye care for the high-risk groups in this district.

Barriers to uptake of referral eye care services among the elderly in residential care: the Hyderabad Ocular Morbidity in Elderly Study (HOMES)

BACKGROUND

To report on the barriers to uptake of eye care services after referral in the elderly in 'homes for the aged' in Hyderabad, India.

METHODS

Individuals aged ≥60 years were recruited from 41 'homes for the aged' and were examined in the 'make-shift' clinics in homes. All participants who had vision impairment or needed further eye examination other than spectacles were referred to the higher centres for 'free services'. Three months after the referral, the participants were interviewed and asked about the uptake of services, and their reasons for not attending.

RESULTS

In all, 731/1182 (61.8%) participants were referred of which 375 (49.9%) attended. In multiple logistic regression, participants aged ≥80 years were less likely to utilise the services (OR 0.60; 95% CI 0.39 to 0.03). Similarly, the participants living in free homes (OR 3.53; 95% CI 2.15 to 5.79) and subsidised homes (OR 2.24: 95% CI 1.55 to 3.23) and those independently mobile had higher odds for uptake of services (OR 5.74; 95% CI 3.31 to 10.51). The major reasons for not availing the referral services were 'lack of felt need' reported by 136 (45.4%) participants followed by other health issues in 100 (33.4%) participants and non-consenting family members in 49 (16.4%) participants. In all, 14 (4.7%) participants gave other reasons.

CONCLUSIONS

The uptake of eye care services in the elderly in residential care remains poor despite the provision of services for free. Lack of felt need for services is the main reason for non-compliance to the referral for care. Counselling on the benefit of interventions could potentially improve referral compliance in this population.

Sex differences in the risk factors of disability among community-dwelling older adults with hypertension: Longitudinal results from the Health, Aging, and Retirement in Thailand study (HART)

Background

Hypertension poses a serious health problem among Thai older adults which could subsequently lead to disability. However, little to no research has been conducted to understand modifiable risk factors of disability among community-dwelling older adults with hypertension in Thailand. In addition, sex is an important social determinant of health, but its role in disability among older adults with hypertension is less clear.

Objectives

This study focused on community-dwelling older adults with hypertension in Thailand and investigated predictors of disability and examined sex differences in the risk factors that were associated with disability in this population.

Methods

Longitudinal data were from the Health, Aging, and Retirement in Thailand (HART) survey (2015-2017; N = 916). The outcome variable was difficulty with the activity of daily living at follow-up. Potential risk factors included sociodemographic information, health behaviors/health status, and disability at baseline. Descriptive analysis and logistic regression analysis were employed to analyze the data.

Results

Most of the participants were female and between aged 60 and 69 years old. Being in an older age group (OR = 1.78, 95% CI: 1.07-2.97, p < 0.05), having more chronic conditions (OR = 1.38, 95% CI: 1.10-1.73, p < 0.01), experiencing obesity (OR = 2.02, 95% CI: 1.11-3.69, p < 0.05), and having disability at baseline (OR = 2.42, 95% CI: 1.09-5.37, p < 0.05) significantly predicted disability at 2 year follow-up among community-dwelling Thai older adults with hypertension. The effects of these risk factors on disability at follow-up did not differ by sex. However, different risk factors of disability were observed across sexes.

Conclusion

The situations of disability among older adults with hypertension in Thailand are likely to aggravate due to the rapid aging of the population. Our analysis provided useful information regarding significant predictors of disability and sex-specific risk factors of disability. Tailored promotion and prevention programs should be readily available to prevent disability among community-dwelling older adults with hypertension in Thailand.

Sex differences in non-communicable disease multimorbidity among adults aged 45 years or older in India

OBJECTIVE

Older male and female adults differ in key characteristics such as disease-specific life expectancy, health behaviours and clinical presentations and non-communicable disease multimorbidity (NCD-MM). Therefore, examining the sex differences in NCD-MM among older adults is vital, as this issue is understudied in low-income and middle-income country (LMIC) contexts such as India, and has been growing in the past few decades.

DESIGN

Large scale nationally representative cross-sectional study.

SETTINGS AND PARTICIPANTS

Longitudinal Ageing Study in India (LASI 2017-2018) had data on 27 343 men and 31 730 women aged 45+, drawn from a sample of 59 073 individuals across India.

PRIMARY AND SECONDARY OUTCOMES MEASURES

We operationalised NCD-MM based on prevalence of the presence of two or more long-term chronic NCD morbidities. Descriptive statistics and bivariate analysis along with multivariate statistics were used.

RESULTS

Women aged 75+ had a higher prevalence of multimorbidity as compared with men (52.1% vs 45.17%). NCD-MM was more common among widows (48.5%) than widowers (44.8%). The female-to-male ratios of ORs (RORs) for NCD-MM associated with overweight/obesity and prior history of chewing tobacco were 1.10 (95% CI: 1.01 to 1.20) and 1.42 (95% CI: 1.12 to 1.80), respectively. The female-to-male RORs show that the odds of NCD-MM were greater in formerly working women (1.24 (95% CI: 1.06 to 1.44)) relative to formerly working men. The effect of increasing NCD-MM on limitations in activities of daily living and instrumental ADL was greater in men than women but reversed for the hospitalisation.

CONCLUSIONS

We found significant sex differences in NCD-MM prevalence among older Indian adults, with various associated risk factors. The patterns underlying these differences warrant greater study, given existing evidence on differential longevity, health burdens and health-seeking patterns all of which operate in a larger structural context of patriarchy. Health systems in turn must respond to NCD-MM mindful of these patterns and aim to redress some of the larger inequities they reflect.

Multimorbidity and multi-disability among the elderly in residential care in India: the Hyderabad Ocular Morbidity in Elderly Study (HOMES)

We report prevalence and risk factors for multimorbidity and multi-disability among elderly people in residential care in the Hyderabad region in South India. In total, 1182 elderly (aged ≥ 60) participants were examined in 41 homes for the aged centres. Detailed interviews were conducted by trained personnel to collect personal and demographic information. A questionnaire was used to assess the history of non-communicable diseases and Washington Disability Questionnaire (WDQ) was administered to assess disabilities. The mean age of the participants was 75.0 years (SD 8.8 years; range: 60-108 years), 35.4% were men, 20.3% had no formal education, 60.7% had school education and 19% had higher education. The prevalence of multimorbidity was 37.6% (95% CI: 34.8-40.4). Prevalence of multi-disability was 23.6% (95% CI: 21.2-26.3; n = 270). In total, 857 (72.5%) participants reported using at least one medication for NCDs. Over a third of the elderly in residential care had multimorbidity, and a quarter of them had multi-disability. A holistic health care system that comprises health and wellness coupled with rehabilitation to address disabilities is needed to achieve healthy aging in elderly in homes for the aged in India.
