Tracing the temporal trends of modifiable risk factors in dementia: insights from the English Longitudinal Study of Ageing (2004-2019).

BACKGROUND: Dementia's growing impact, especially in ageing societies such as the UK, emphasises the importance of modifiable risk factors as primary prevention targets. Despite this, the temporal progression and the population attributable fraction (PAF) of dementia attributable to these factors remain unclear. This investigation aims to examine the temporal trajectories of the modifiable risk factors for dementia in England from 2004 to 2019. METHODS: We used data from the English Longitudinal Study of Ageing collected between June, 2004, and July, 2019, covering 76 904 participants. We calculated the PAFs for 12 modifiable risk factors, as recommended by the Lancet Commission on dementia prevention, intervention, and care, and the individual weighted PAFs (IW-PAFs) for each risk factor. We analysed temporal trends to understand the changes in the overall PAF and IW-PAF over the study period. FINDINGS: The overall PAF for dementia showed a decrease from 46·31% in 2004-05 to 43·95% in 2018-19, but this trend was not significant (p=0·226). Hypertension, with an average IW-PAF of 8·67%, has been the primary modifiable determinant of dementia, trailed by obesity (6·42%), social isolation (5·84%), hearing loss (5·02%), depression (4·89%), low education (4·80%), physical inactivity (3·40%), diabetes (2·61%), smoking (2·08%), excessive alcohol consumption (1·22%), air pollution (0·44%), and traumatic brain injury (0·28%). During 2004-19, only IW-PAFs of low education (p=0·001), social isolation (p=0·034), and smoking (p=0·007) showed significant decreasing trends, whereas IW-PAFs of other factors had either stagnated with insignificant changes or, worryingly, climbed upwards. INTERPRETATION: This investigation provides valuable insights into the temporal trends of modifiable risk factors for dementia in England. The observed trends underscore the continuing relevance of these risk factors and the need for targeted public health strategies to address them. Notable, PAF was based on a theoretical scenario in which dementia risk can be wholly eliminated by removing risk factors, which should be explained with caution in practice.

Temporal trends in population attributable fractions of modifiable risk factors for dementia: a time-series study of the English Longitudinal Study of Ageing (2004-2019).

BACKGROUND: Interest in modifiable risk factors (MRFs) for dementia is high, given the personal, social, and economic impact of the disorder, especially in ageing societies such as the United Kingdom. Exploring the population attributable fraction (PAF) of dementia attributable to MRFs and how this may have changed over time remains unclear. Unravelling the temporal dynamics of MRFs is crucial for informing the development of evidence-based and effective public health policies. This investigation examined the temporal trajectories of MRFs for dementia in England. METHODS: We used data from the English Longitudinal Study of Ageing, a panel study over eight waves collected between 2004 and 2019 (76,904 interviews in total). We calculated the PAFs for twelve MRFs (including six early- to mid-life factors and six late-life factors), as recommended by the Lancet Commission, and the individual weighted PAFs (IW-PAFs) for each risk factor. Temporal trends were analysed to understand the changes in the overall PAF and IW-PAF over the study period. Subgroup analyses were conducted by sex and socioeconomic status (SES). RESULTS: The overall PAF for dementia MRFs changed from 46.73% in 2004/2005 to 36.79% in 2018/2019, though this trend was not statistically significant. During 2004-2019, hypertension, with an average IW-PAF of 8.21%, was the primary modifiable determinant of dementia, followed by obesity (6.16%), social isolation (5.61%), hearing loss (4.81%), depression (4.72%), low education (4.63%), physical inactivity (3.26%), diabetes mellitus (2.49%), smoking (2.0%), excessive alcohol consumption (1.16%), air pollution (0.42%), and traumatic brain injury (TBI) (0.26%). During 2004-2019, only IW-PAFs of low education, social isolation, and smoking showed significant decreasing trends, while IW-PAFs of other factors either did not change significantly or increased (including TBI, diabetes mellitus, and air pollution). Upon sex-specific disaggregation, a higher overall PAF for MRFs was found among women, predominantly associated with later-life risk factors, most notably social isolation, depression, and physical inactivity. Additionally, hearing loss, classified as an early- to mid-life factor, played a supplementary role in the identified sex disparity. A comparable discrepancy was evident upon PAF evaluation by SES, with lower income groups experiencing a higher dementia risk, largely tied to later-life factors such as social isolation, physical inactivity, depression, and smoking. Early- to mid-life factors, in particular, low education and obesity, were also observed to contribute to the SES-associated divergence in dementia risk. Temporal PAF and IW-PAF trends, stratified by sex and SES, revealed that MRF PAF gaps across sex or SES categories have persisted or increased. CONCLUSIONS: In England, there was little change over time in the proportion of dementia attributable to known modifiable risk factors. The observed trends underscore the continuing relevance of these risk factors and the need for targeted public health strategies to address them.

Co-development of a training programme on disability for healthcare workers in Uganda.

BACKGROUND: Approximately 1.3 billion people worldwide face barriers in accessing inclusive healthcare due to disabilities, leading to worse health outcomes, particularly in low and middle-income countries (LMIC). However, there is a lack of training of healthcare workers about disability, both globally and in Uganda. OBJECTIVES: To use mixed research methods to develop a comprehensive training program with standardisedelements for healthcare workers in Uganda, focusing on improving their knowledge, attitudes, and skills inproviding care for people with disabilities. METHODS: The Medical Research Council (MRC) approach was employed to guide the development of the training intervention. We conducted an umbrella review to gather relevant literature on disability training for healthcare workers. Interviews were conducted with international experts to gain insights and perspectives on the topic. Additionally, interviews were undertaken with people with disabilities and healthcare workers in Uganda to understand their experiences and needs. A participatory workshop was organised involving key stakeholders, to collaboratively design the training material based on the findings from these data sources. RESULTS: Eight review articles examined training programs for healthcare workers on disability. Training settings ranged from specialised clinical settings to non-clinical settings, and the duration and evaluation methods of the training varied widely. Lectures and didactic methods were commonly used, often combined with other approaches such as case studies and simulations. The impact of the training was assessed through healthcare worker reports on attitudes, knowledge, and self-efficacy. Interviews emphasised the importance of involving people with disabilities in the training and improving communication and understanding between healthcare providers and people with disabilities. Five themes for a training on disability for healthcare workers were generated through the workshop, including responsibilities and rights, communication, informed consent, accommodation, and referral and connection, which were used to guide the development of the curriculum, training materials and training approach. CONCLUSION: This study presents a novel approach to develop a training program that aims to enhance healthcare services for people with disabilities in Uganda. The findings offer practical insights for the development of similar programs in LMICs. The effectiveness of the training program will be evaluated through a pilot test, and policy support is crucial for its successful implementation at scale.

KEY MESSAGES: 1. Healthcare workers require training to effectively address the health concerns of people with disabilities, yet this is rarely included in curricula worldwide. 2. Uganda recognises the importance of addressing this issue and is taking steps to improve training programs about disability for healthcare workers. 3. We used multiple research methods (umbrella review, semi-structured interviews, participatory research and collaborative design) to co-develop a comprehensive training program with standardised elements for healthcare workers in Uganda, focusing on improving their knowledge, attitudes, and skills in providing care for people with disabilities. 4. The developed training material could be adapted for healthcare workers in other resource-limited settings, and policy support is needed to ensure its implementation at scale.

Sexual behaviours and sexual health among middle-aged and older adults in Britain.

OBJECTIVES: Population-representative studies of the sexual health of middle-aged and older adults are lacking in ageing societies. This study aimed to identify latent patterns of sexual behaviours and health of people aged 45-74 years. METHODS: We conducted a latent class analysis of the National Attitudes and Sexual Lifestyles Survey (Natsal-3), a nationally representative survey conducted in Britain in 2011. RESULTS: Of the 5260 respondents aged 45-74 years, 48.86% of men and 44.91% of women belonged to the Content Caseys class who reported good sexual health. The Infrequent Indigos (30.94% of men, 44.38% of women) were characterised by a lack of sexual activity, reported some dissatisfaction, and were more likely to have a disability. The Low-Functioning Lees (11.65% of men, 8.41% of women) reported some more disability and had issues with sexual functioning and higher levels of distress. The Multiple-Partnered Morgans (8.62% of men, 2.30% of women) were characterised by a greater number of sexual partners and several risk behaviours. CONCLUSIONS: The use of these four classes can aid in improved targeting of tailored sexual health services to improve sexual function, sexual satisfaction, reduce distress and risky behaviours among middle-aged and older adults. These services should be inclusive of the disabled community.

Impacts of the COVID-19 pandemic on access to healthcare among people with disabilities: evidence from six low- and middle-income countries.

BACKGROUND: The pandemic has placed considerable strain on health systems, especially in low- and middle-income countries (LMICs), leading to reductions in the availability of routine health services. Emerging evidence suggests that people with disabilities have encountered marked challenges in accessing healthcare services and supports in the context of the pandemic. Further research is needed to explore specific barriers to accessing healthcare during the pandemic, and any strategies that promoted continued access to health services in LMICs where the vast majority of people with disabilities live. METHODS: Qualitative in-depth interviews were conducted with persons with disabilities in Ghana, Zimbabwe, Viet Nam, Türkiye (Syrian refugees), Bangladesh, and India as part of a larger project exploring the experiences of people with disabilities during the COVID-19 pandemic and their inclusion in government response activities. Data were analysed using thematic analysis. RESULTS: This research found that people with disabilities in six countries - representing a diverse geographic spread, with different health systems and COVID-19 responses - all experienced additional difficulties accessing healthcare during the pandemic. Key barriers to accessing healthcare during the pandemic included changes in availability of services due to systems restructuring, difficulty affording care due to the economic impacts of the pandemic, fear of contracting coronavirus, and a lack of human support to enable care-seeking. CONCLUSION: These barriers ultimately led to decreased utilisation of services which, in turn, negatively impacted their health and wellbeing. However, we also found that certain factors, including active and engaged Organisations of Persons with Disabilities (OPDs) and Non-Governmental Organizations (NGOs) played a role in reducing some of the impact of pandemic-related healthcare access barriers.

Relationship between hearing loss and depression symptoms among older adults in China: The mediating role of social isolation and loneliness.

OBJECTIVES: To evaluate whether social isolation and loneliness mediates the relationship between hearing loss and depression symptoms in older adults in China. METHODS: A cross-sectional analysis was conducted of 3769 participants (aged≥60 years) in Shandong province of China. Hearing loss was assessed using Pure-Tone Audiometry test, depression symptoms using 15-item Geriatric Depression Scale, loneliness through UCLA Loneliness Scale and social isolation using Lubben Social Network Scale. Regression and bootstrap analyses were performed to test both direct associations of hearing loss and depression symptoms, and whether the mediating role of social isolation and loneliness. RESULTS: Overall, 44% of older adults had hearing loss, which was generally mild (30%) rather than moderate (10%), severe (3%) or profound (0.6%). Increasing levels of hearing loss was associated with increasing levels of social isolation and depressions. Hearing loss was also associated with loneliness, but here a threshold effect was apparent and no trend for increasing loneliness with increasing hearing loss. Models that included social isolation and loneliness showed an amelioration in the association of hearing loss and depression, although it remained significant at all levels of hearing loss. Overall, 8% of the total effect of hearing loss on depression symptoms was explained by the mediated effect through social isolation and 42% by loneliness. CONCLUSIONS: Psychosocial factors such as social isolation and loneliness might explain the association between hearing loss and depression. Interventions that address older adults' social isolation and loneliness may ameliorate depression in older adults with hearing loss.

Prevalence and characteristics of hearing and vision loss in preschool children from low income South African communities: results of a screening program of 10,390 children.

BACKGROUND: The majority of children with sensory impairments live in low- and middle-income countries. More studies of hearing and vision impairment prevalence are needed, in order to generate more accurate estimates of trends in sensory impairments. This study aimed to estimate the prevalence and describe the characteristics of hearing and vision loss among preschool children (4-7 years) in an underserved South African community following community-based mobile health (mHealth) supported hearing and vision services. METHODS: A screening program of sensory impairments was undertaken of children attending preschools in the communities of Khayelitsha and Mitchell's Plain, Cape Town, from September 2017 until June 2019. Hearing and vision screening were done by trained community health workers using mHealth technology. Children who failed hearing and vision screening were seen for follow-up assessments at their preschools. Follow-up assessments were conducted using smartphones that host point-of-care validated and calibrated hearing and vision testing applications (hearTest app, hearX Group, South Africa and PeekAcuity app, Peek Vision, United Kingdom). Descriptive statistical analysis and logistic regression analysis were conducted after extracting data from a secure cloud-based server (mHealth Studio, hearX Group) to Microsoft Excel (2016). RESULTS: A total of 10,390 children were screened at 298 preschools over 22 months. Of the children screened, 5.6 and 4.4% of children failed hearing and vision screening respectively. Community-based follow-up hearing tests were done at the preschools on 88.5% (514) of children of whom 240 children (54.2% female) presented with hearing loss. A preschool-based follow-up vision test was done on 400 children (88.1%). A total of 232 children (46.1% female) had a vision impairment, and a further 32 children passed the test but had obvious signs of ocular morbidity. Logistic regression analysis found that age was a significant predictor of vision loss (p < 0.05), but not for hearing loss (p = 0.06). Gender was not a significant predictor of hearing (p = 0.22) or vision loss (p = 0.20). CONCLUSIONS: Hearing loss is prevalent in at least 22 per 1000 and vision loss in at least 23 per 1000 preschool children in an underserved South African community. Timely identification of sensory losses can be facilitated through community-based hearing and vision services supported by mHealth technology.

m-Health Applications for Hearing Loss: A Scoping Review.

Introduction: Mobile health (m-health) has the potential to improve access and uptake of health services globally. Noncommunicable diseases such as hearing loss have seen increasing use of m-health approaches to improve access, scalability, penetration, quality, and convenience of health services. This scoping review describes published research in m-health supported hearing health care services across the continuum of care. Methods: A search on Scopus, MEDLINE (PubMed), and Web of Science for articles published up to July 2, 2021 was conducted. Articles in which m-health was used across a continuum of care where the primary focus was hearing health care were included. A narrative synthesis was conducted. Results: One hundred forty-six articles meeting the inclusion criteria were included in data extraction. High-income countries contributed 56% of articles, upper-middle countries 32%, lower-middle countries 8%, and low-income countries 4%. Articles identified included promotion (2%), screening (39%), diagnosis (35%), treatment (10%), and support (14%) for hearing loss. m-Health applications in high-income countries were more represented in diagnosis (62% vs. 38%), treatment (67% vs. 33%), and support (82% vs. 18%) compared with low- and middle-income countries (LMICs) except for screening (64% vs. 36%). Few studies focussed on hearing health promotion across all income brackets. Conclusions: m-Health supported hearing health care services are available across a continuum of care and various world regions, although more prevalent in high-income countries. Although great potential is demonstrated, implementation evaluations are important to further validate its widespread use and potential to make services for hearing loss more accessible in LMICs.

Estimating assistive product need in Cameroon and India: results of population-based surveys and comparison of self-report and clinical impairment assessment approaches.

OBJECTIVES: To estimate population need and coverage for distance glasses, hearing aids and wheelchairs in India and Cameroon, and to explore the relationship between assistive product (AP) need measured through self-report and clinical impairment assessment. METHODS: Population-based surveys of approximately 4000 people each were conducted in Mahabubnagar district, India and Fundong district, Cameroon. Participants underwent standardised vision, hearing and musculoskeletal impairment assessment to assess need for distance glasses, hearing aids, wheelchairs. Participants with moderate or worse impairment and/or self-reported difficulties in functioning were also asked about their self-reported AP need. RESULTS: 6.5% (95% CI 5.4-7.9) in India and 1.9% (95% CI 1.5-2.4) in Cameroon of the population needed at least one of the three APs based on moderate or worse impairments. Total need was highest for distance glasses [3.7% (95% CI 2.8-4.7) India; 0.8% (95% CI 0.5-1.1), Cameroon] and lowest for wheelchairs (0.1% both settings; 95% CI 0.03-0.3 India, 95% CI 0.04-0.3 Cameroon). Coverage for each AP was below 40%, except for distance glasses in India, where it was 87% (95% CI 77.1-93.0). The agreement between self-report and clinical impairment assessment of AP need was poor. For instance, in India, 60% of people identified through clinical assessment as needing distance glasses did not self-report a need. Conversely, in India, 75% of people who self-reported needing distance glasses did not require one based on clinical impairment assessment. CONCLUSIONS: There is high need and low coverage of three APs in two low-and middle-income settings. Methodological shortcomings highlight the need for improved survey methods compatible with the international classification of functioning, disability and health to estimate population-level need for AP and related services to inform advocacy and planning.

OBJECTIFS: Estimer les besoins et la couverture de la population en lunettes de distance, appareils auditifs et chaises roulantes en Inde et au Cameroun; et explorer la relation entre les besoins en produits d'assistance (PA) mesurés par l'auto-déclaration et l'évaluation clinique de la déficience. MÉTHODES: Enquêtes de population sur environ 4.000 personnes, chacune menées dans le district de Mahabubnagar, en Inde et dans le district de Fundong, au Cameroun. Les participants ont subi une évaluation standardisée de la vision, de l'audition et des troubles musculosquelettiques pour évaluer les besoins en lunettes de distance, en appareils auditifs et en chaises roulantes. Les participants ayant une déficience modérée ou sévère et/ou des difficultés fonctionnelles autodéclarées ont également été interrogés sur leurs besoins autodéclarés en PA. RÉSULTATS: 6,5% (IC95%: 5,4-7,9) de la population en Inde et 1,9% (IC95%: 1,5-2,4) au Cameroun avait besoin d'au moins l'un des trois PA sur la base de déficiences modérées ou sévères. Le besoin total était le plus élevé pour les lunettes de distance [3,7% (IC95%: 2,8-4,7) Inde; 0,8% (IC95%: 0,5-1,1), Cameroun] et le plus faible pour les chaises roulantes (0,1% dans les deux paramètres; IC95%: 0,03-0,3 Inde, IC95%: 0,04-0,3 Cameroun). La couverture pour chaque PA était inférieure à 40%, sauf pour les lunettes de distance en Inde, où elle était de 87% (IC95%: 77,1-93,0). La concordance entre l'auto-déclaration et l'évaluation clinique de la déficience du besoin en PA était faible. Par exemple, en Inde, 60% des personnes identifiées lors de l'évaluation clinique comme ayant besoin de lunettes de distance n'ont pas autodéclaré un besoin. A l'inverse, en Inde, 75% des personnes qui ont déclaré avoir besoin de lunettes de distance n'en avaient pas besoin sur la base d'une évaluation clinique de la déficience. CONCLUSIONS: Il y a un besoin élevé et une faible offre de trois PA dans deux milieux à revenu faible et intermédiaire. Les lacunes méthodologiques soulignent le besoin de méthodes d'enquête améliorées compatibles avec la classification internationale du fonctionnement, du handicap et de la santé pour estimer les besoins au niveau de la population en PA et en services connexes pour éclairer le plaidoyer et la planification.

Are Nepal's water, sanitation and hygiene and menstrual hygiene policies and supporting documents inclusive of disability? A policy analysis.

PURPOSE: This study assesses the inclusion of disability in Nepal's policy and guidance relevant to water, sanitation and hygiene (WASH), and menstrual hygiene management (MHM) in comparison to gender. We investigated both policy formulation and implementation, using the Kavrepalanchok district as a case study. MATERIALS AND METHODS: We used the EquiFrame framework, adapted for disability and gender, and focusing on WASH and MHM. Ten Nepali policies and guidance documents were reviewed and scored for quality against the framework, which included 21 core concepts of human rights. We also interviewed key informants to consider the inclusion of disability in the implementation of MHM interventions. We applied stratified purpose sampling to 12 government officials and service providers working in Kathmandu and the Kavrepalanchock district; conducted in-depth interviews and analysed data thematically using Nvivo 11. RESULTS: Disability was inadequately covered within the policy documents, and MHM policy commitments for disability were almost non-existent. Participation of people with disabilities in policy development was limited; within Kavrepalanchok, policy commitments were not implemented as intended and disability service providers were unable to allocate government resources. Inadequate data on disability and MHM resulted in limited professional understanding of the issues, as service providers had no training. A narrow WASH infrastructure approach to improving MHM for people with disabilities was prioritised. MHM interventions were delivered in schools; these failed to reach children with disabilities who are often out of school. Finally, there were indications that some caregivers seek sterilisation for people with disabilities who are unable to manage menstruation independently. CONCLUSION: Though the Constitution of Nepal enshrines gender equality and disability inclusion, there are consistent gaps in attention to disability and MHM in policies and practice. These omit and exclude people with disabilities from MHM interventions. Investment is required to generate evidence on the MHM barriers faced by people with disabilities, which would then be drawn on to develop training on these issues for professionals to improve understanding. Subsequently, policy makers could include more concepts of human rights against disability in relevant policies and service providers could implement policy commitments as intended.

Qualitative study exploring the barriers to menstrual hygiene management faced by adolescents and young people with a disability, and their carers in the Kavrepalanchok district, Nepal.

BACKGROUND: Menstrual hygiene management (MHM) is a recognised public health, social and educational issue, which must be achieved to allow the realisation of human rights. People with disabilities are likely to experience layers of discrimination when they are menstruating, but little evidence exists. METHODS: The study aims to investigate barriers to MHM that people with disabilities and their carers face in the Kavrepalanchok, Nepal, using qualitative methods. Twenty people with disabilities, aged 15-24, who menstruate and experience 'a lot of difficulty' or more across one or more of the Washington Group functional domains were included, as well as 13 carers who provide menstrual support to these individuals. Purposeful sampling was applied to select participants. Different approaches were used to investigating barriers to MHM and triangulate data: in-depth interviews, observation, PhotoVoice and ranking. We analysed data thematically, using Nvivo 11. RESULTS: Barriers to MHM experienced by people with disabilities differ according to the impairment. Inaccessible WASH facilities were a major challenge for people with mobility, self-care and visual impairments. People with intellectual impairments had difficulty accessing MHM information and their carers despaired when they showed their menstrual blood to others, which could result in abuse. No support mechanisms existed for carers for MHM, and they felt overwhelmed and isolated. Menstrual discomfort was a major challenge; these were managed with home remedies, or not at all. Most participants followed menstrual restrictions, which were widespread and expected; many feared they would be cursed if they did not. As disability is often viewed as a curse, this demonstrates the layers of discrimination faced. CONCLUSION: Issues related to MHM for people with disabilities is more complex than for others in the population due to the additional disability discrimination and impairment experienced. Research exploring these issues must be conducted in different settings, and MHM interventions, tailored for impairment type and carers requirements,should be developed. Attention to, and resourcing for disability inclusive MHM must be prioritised to ensure 'no one is left behind'.

Childhood musculoskeletal impairment in Malawi from traumatic and non-traumatic causes: a population- based assessment using the key informant method.

BACKGROUND: Musculoskeletal impairment (MSI) in children is an under-recognised public health challenge. Although preventable, road injuries and other traumas continue to cause significant impairments to children worldwide. The study aimed to use the Key Informant Method (KIM) to assess prevalence and causes of MSI in children in two districts in Malawi, estimating the associated need for services provision, with a focus on traumatic aetiology. METHODS: The KIM was conducted in the districts of Thyolo (Southern Malawi) and Ntcheu (Central Malawi) in 2013. Five hundred key informants were trained to identify children who may have one of a range of MSI. The identified children were referred to a screening camp where they were examined by medical experts with standardised assessment protocols for diagnosing each form of impairment. RESULTS: 15,000 children were referred to screening camps. 7220 children were assessed (response rate 48%) for an impairment of whom 15.2% (1094) had an MSI. 13% of children developed MSI from trauma, while 54% had a neurological aetiology. For MSI of traumatic origin the most common body part affected was the elbow. Less than half of children with MSI (44.4%) were enrolled in school and none of these children attended schools with resources for disability. More than half of children with MSI (60%) had not received required services and 64% required further physical therapy. CONCLUSIONS: The KIM method was used to identify a high prevalence of MSI among children in two districts of Malawi and estimates an unmet need for dedicated MSI services.

Disability-inclusive responses to COVID-19: Lessons learnt from research on social protection in low- and middle-income countries.

The one billion people living with disabilities globally already face a heightened risk of poverty, which will likely be exacerbated by the COVID-19 pandemic unless interventions to address its economic impacts are disability-inclusive. This paper draws on the literature on disability, poverty and social protection in low- and middle-income countries to explore the pathways through which the current pandemic may increase the risk of poverty amongst people with disabilities, such as loss of income from disruptions to work, particularly in the informal sector, and higher future spending and productivity losses from disruptions to healthcare and other key services (e.g. rehabilitation, assistive devices). It also explores how social protection and other initiatives to mitigate the economic impacts of the pandemic should consider the needs of people with disabilities, with recommendations for disability-inclusive actions in the design and implementation of eligibility criteria and application procedures, as well as the delivery and content of benefits. Across recommendations, meaningful consultations with people with disabilities, leadership at the program and policy level, appropriate budgeting and monitoring of progress through routine collection of data on disability are key for improving access to and impact of economic responses amongst people with disabilities.

Effect of supplemental nutrition in pregnancy on offspring's risk of cardiovascular disease in young adulthood: Long-term follow-up of a cluster trial from India.

BACKGROUND: Undernutrition during intrauterine life and early childhood is hypothesised to increase the risk of cardiovascular disease (Developmental Origins of Health and Disease Hypothesis), but experimental evidence from humans is limited. This hypothesis has major implications for control of the cardiovascular disease epidemic in South Asia (home to a quarter of world's population), where a quarter of newborns have low birth weight. We investigated whether, in an area with prevalent undernutrition, supplemental nutrition offered to pregnant women and their offspring below the age of 6 years was associated with a lower risk of cardiovascular disease in the offspring when they were young adults. METHODS AND FINDINGS: The Hyderabad Nutrition Trial was a community-based nonrandomised controlled intervention trial conducted in 29 villages near Hyderabad, India (1987-1990). Protein-calorie food supplement was offered daily to pregnant and lactating women (2.09 MJ energy and 20-25 g protein) and their offspring (1.25 MJ energy and 8-10 g protein) until the age of six years in the 15 intervention villages, but not in the 14 control villages. A total of 1,826 participants (949 from the intervention villages and 877 from the control villages, representing 70% of the cohort) at a mean age of 21.6 years (62% males) were examined between 2009 and 2012. The mean body mass index (BMI) of the participants was 20 kg/m2 and the mean systolic blood pressure was 115 mm Hg. The age, sex, socioeconomic position, and urbanisation-adjusted effects of intervention (beta coefficients and 95% confidence intervals) on outcomes were as follows: carotid intima-media thickness, 0.01 mm (-0.01 to 0.03), p = 0.36; arterial stiffness (augmentation index), -1.1% (-2.5 to 0.3), p = 0.097; systolic blood pressure, 0.5 mm Hg (-0.6 to 1.6), p = 0.36; BMI, -0.13 kg/m2 (-0.75 to 0.09), p = 0.093; low-density lipoprotein (LDL) cholesterol, 0.06 mmol/L (-0.07 to 0.2), p = 0.37; and fasting insulin (log), -0.06 mU/L (-0.19 to 0.07), p = 0.43. The limitations of this study include nonrandomised allocation of intervention and lack of data on compliance, and potential for selection bias due to incomplete follow-up. CONCLUSIONS: Our results showed that in an area with prevalent undernutrition, protein-calorie food supplements offered to pregnant women and their offspring below the age of 6 years were not associated with lower levels of cardiovascular risk factors among offspring when they were young adults. Our findings, coupled with evidence from other intervention studies to date, suggest that policy makers should attach limited value to cardiovascular health benefits of maternal and child protein-calorie food supplementation programmes.

The relationship between mental health conditions and hearing loss in low- and middle-income countries.

OBJECTIVE: Hearing loss can have far-reaching effects on social, emotional and cognitive development, but few studies have addressed the link with mental health conditions. We conducted a systematic review of the association between hearing loss and mental health conditions in low- and middle-income countries (LMICs). METHODS: We searched six electronic databases using predetermined criteria to retrieve original research reporting mental health in people with hearing loss. We considered quantitative studies measuring any type of mental health conditions according to the ICD10 classifications of 'Mental and behavioural disorders' in relation to any measure of hearing loss. We assessed risk of bias using a set of criteria according to the SIGN50 guidelines. RESULTS: We included 12 studies evaluating 35 604 people with hearing loss in 10 countries. Poorer mental health (measured as stress and anxiety, depression, and/or behavioural and emotional disorders) was more common among people with hearing loss compared to those without in 10 studies. One study found no difference in mental health outcomes between people with hearing, visual and no impairment. Another study reported that after hearing aids, those with severe hearing loss had significant improvement in psychosocial function, compared to no change among those without hearing loss. Overall, one study was judged to be high quality, seven medium quality and four low quality. CONCLUSIONS: Included studies showed a trend towards poorer mental health outcomes for people with hearing loss than for those without. However, our findings indicate that very few high-quality studies have been conducted in LMICs.

OBJECTIF: La perte auditive peut avoir des effets de grande envergure sur le développement social, émotionnel et cognitif, mais peu d'études ont abordé le lien avec les conditions de santé mentale . Nous avons effectué une revue systématique de l'association entre la perte auditive et les conditions de santé mentale dans les pays à revenu faible ou intermédiaire (PRFI). MÉTHODES: Nous avons effectué des recherches dans six bases de données électroniques en utilisant des critères prédéterminés pour récupérer des recherches originales faisant état de la santé mentale chez les personnes ayant une perte auditive. Nous avons considéré des études quantitatives mesurant tout type de conditions de santé mentale selon les classifications de la ICD10 des «troubles mentaux et comportementaux¼ par rapport à toute mesure de la perte auditive. Nous avons évalué le risque de biais en utilisant un ensemble de critères selon les directives SIGN50. RÉSULTATS: Nous avons inclus 12 études évaluant 35.604 personnes malentendantes dans 10 pays. Une mauvaise santé mentale (mesurée en termes de stress et d'anxiété, de dépression et/ou de troubles comportementaux et émotionnels) était plus fréquente chez les personnes malentendantes que chez les personnes non atteintes dans 10 études. Une étude n'a trouvé aucune différence dans les résultats de santé mentale entre les personnes ayant une déficience auditive, visuelle et celles sans déficience. Une autre étude a rapporté qu'après les prothèses auditives, les personnes souffrant de perte auditive sévère avaient une amélioration significative de la fonction psychosociale, par rapport à aucun changement chez celles sans perte auditive. Dans l'ensemble, une étude a été jugée de haute qualité, 7 de qualité moyenne et 4 de faible qualité. CONCLUSIONS: Les études incluses ont montré une tendance vers de moins bons résultats de santé mentale pour les personnes avec que pour celles sans perte auditive. Cependant, nos résultats indiquent que très peu d'études de haute qualité ont été menées dans les PRFI.

Field test of the Rapid Assessment of Hearing Loss survey protocol in Ntcheu district, Malawi.

Objective: (1) To test the feasibility of the Rapid Assessment of Hearing Loss (RAHL) survey protocol in Malawi (Ntcheu); (2) To estimate the prevalence and probable causes of hearing loss (adults 50+).Design: Cross-sectional population-based survey.Study sample: Clusters (n = 38) were selected using probability-proportionate-to-size-sampling. Within each cluster, 30 people aged 50+ were selected using compact-segment-sampling. All participants completed smartphone-based audiometry (hearTest). Prevalence was estimated using WHO definitions (PTA of thresholds 0.5, 1, 2, 4 kHz in the better ear of >25 dB HL (any) and >40 dB HL (≥moderate)). Otoscopy and questionnaire were used to assess probable causes. Participants with hearing loss and/or ear disease were asked about care-seeking and barriers.Results: Four teams completed the survey in 24 days. 1080 of 1153 (93.7%) participants were examined. The median time to complete the protocol was 24 min/participant. Prevalence of hearing loss was 35.9% (95% CI = 31.6-40.2) (any level); and 10.0% (95% CI = 7.9-12.5) (≥moderate). The majority was classified as probable sensorineural. Nearly one third of people (30.9%) needed diagnostic audiology services and possible hearing aid fitting. Hearing aid coverage was <1%. Lack of perceived need was a key barrier.Conclusion: The RAHL is simple, fast and provides information about the magnitude and probable causes of hearing loss to plan services.

Children with hearing impairment in Malawi, a cohort study.

OBJECTIVE: To assess the outcomes of children diagnosed with hearing impairment 3 years earlier in terms of referral uptake, treatment received and satisfaction with this treatment, and social participation. METHODS: We conducted a population-based longitudinal analysis of children with a hearing impairment in two rural districts of Malawi. Key informants within the community identified the cohort in 2013 (baseline). Informants clinically screened children at baseline, and by questionnaires at baseline and follow-up in 2016. We investigated associations between sociodemographic characteristics and outcomes by multivariate logistic regression. RESULTS: We diagnosed 752 children in 2013 as having a hearing impairment and traced 307 (40.8%) children of these for follow-up in 2016. Referral uptake was low (102/184; 55.4%), more likely among older children (odds ratio, OR: 3.5; 95% confidence interval, CI: 1.2-10.2) and less likely for those with an illiterate caregiver (OR: 0.5; 95% CI: 0.2-0.9). Few of the children who attended hospital received any treatment (33/102; 32.4%) and 63.6% (21/33) of caregivers reported satisfaction with treatment. Difficulty making friends and communicating needs was reported for 10.0% (30/299) and 35.6% (107/301) of the children, respectively. Lack of school enrolment was observed for 29.5% (72/244) of children, and was more likely for older children (OR: 28.6; 95% CI: 10.3-79.6), girls (OR: 2.4; 95% CI: 1.2-4.8) and those with an illiterate caregiver (OR: 2.1; 95% CI: 1.0-4.1). CONCLUSION: More widespread and holistic services are required to improve the outcomes of children with a hearing impairment in Malawi.

Hearing and vision screening for preschool children using mobile technology, South Africa.

OBJECTIVE: To implement and evaluate a community-based hearing and vision screening programme for preschool children in the Western Cape, South Africa, supported by mobile health technology (mHealth) and delivered by community health workers (CHWs). METHODS: We trained four CHWs to provide dual sensory screening in preschool centres of Khayelitsha and Mitchells Plain during September 2017-December 2018. CHWs screened children aged 4-7 years using mHealth software applications on smartphones. We used logistic regression analysis to evaluate the association between screening results and age, sex and test duration, and, for hearing, excessive background noise levels. RESULTS: CHWs screened 94.4% (8023/10 362) of eligible children at 271 centres at a cost of 5.63 United States dollars per child. The number of children who failed an initial hearing and visual test was 435 (5.4%) and 170 (2.1%), respectively. Hearing test failure was associated with longer test times (odds ratio, OR: 1.022; 95% confidence interval, CI: 1.021-1.024) and excessive background noise levels at 1 kilohertz (kHz) (e.g. OR for left ear: 1.688; 95% CI: 1.198-2.377). Visual screening failure was associated with longer test duration (OR: 1.003; 95% CI: 1.002-1.005) and younger age (OR: 0.629; 95% CI: 0.520-0.761). Of the total screened, 111 (1.4%) children were diagnosed with a hearing and/or visual impairment. CONCLUSION: mHealth-supported CHW-delivered hearing and vision screening in preschool centres provided a low-cost, acceptable and accessible service, contributing to lower referral numbers to resource-constrained public health institutions.

Prevalence of Hearing Impairment in Mahabubnagar District, Telangana State, India.

OBJECTIVES: To estimate the prevalence of hearing impairment in Mahabubnagar district, Telangana state, India. METHODS: A population-based prevalence survey of hearing impairment was undertaken in 2014. Fifty-one clusters of 80 people aged 6 months and older were selected using probability-proportionate-to-size sampling. A two-stage hearing screening was conducted using otoacoustic emissions on all participants followed by pure-tone audiometry on those aged 4 years and older who failed otoacoustic emissions. Cases of hearing impairment were defined using the World Health Organization definition of disabling hearing impairment: a pure-tone average of thresholds at 500, 1000, 2000, and 4000 Hz of ≥41 dB HL for adults and ≥31 dB HL for children based on the better ear. Possible causes of hearing impairment were ascertained by a certified audiologist. Reported hearing difficulties were also measured in this survey and compared with audiometry results. RESULTS: Three thousand five hundred seventy-three people were examined (response rate 87%), of whom 52% were female. The prevalence of disabling hearing impairment was 4.5% [95% confidence interval (CI) = 3.8 to 5.3). Disabling hearing impairment prevalence increased with age from 0.4% in those aged 4 to 17 years (95% CI = 0.2 to 1.1) to 34.7% (95% CI = 28.7 to 41.1) in those aged older than 65 years. No difference in prevalence was seen by sex. Ear examination suggested that the possible cause of disabling hearing impairment was chronic suppurative otitis media for 6.9% of cases and dry perforation for 5.6% cases. For the vast majority of people with disabling hearing impairment, a possible cause could not be established. The overall prevalence of reported or proxy reported hearing impairment was 2.6% (95% CI = 2.0 to 3.4), and this ranged from 0.6% (95% CI = 0.08 to 4.4) in those aged 0 to 3 years to 14.4% (95% CI = 9.8 to 20.7) in those aged older than 65 years. CONCLUSIONS: Disabling hearing impairment in Telangana State is common, affecting approximately 1 in 23 people overall and a third of people aged older than 65 years. These findings suggest that there are a substantial number of individuals with hearing impairment who could potentially benefit from improved access to low-cost interventions.

A case-control study of musculoskeletal impairment: association with socio-economic status, time use and quality of life in post-conflict Myanmar.

BACKGROUND: Musculoskeletal impairments (MSI) are a major global contributor to disability. Evidence suggests entrenched cyclical links between disability and poverty, although few data are available on the link of poverty with MSI specifically. More data are needed on the association of MSI with functioning, socio-economic status and quality of life, particularly in resource-poor settings where MSI is common. METHODS: We undertook a case-control study of the association between MSI and poverty, time use and quality of life in post-conflict Myanmar. Cases were recruited from two physical rehabilitation service-centres, prior to the receipt of any services. One age- (+/- 5 years of case's age) and sex- matched control was recruited per case, from their home community. 108 cases and 104 controls were recruited between July - December 2015. Cases and controls underwent in-depth structured interviews and functional performance tests at multiple time points over a twelve-month period. The baseline characteristics of cases and controls are reported in this manuscript, using multivariate logistic regression analysis and various tests of association. RESULTS: 89% of cases were male, 93% were lower limb amputees, and the vast majority had acquired MSI in adulthood. 69% were not working compared with 6% of controls (Odds Ratio 27.4, 95% Confidence Interval 10.6-70.7). Overall income, expenditure and assets were similar between cases and controls, with three-quarters of both living below the international LMIC poverty line. However, cases' health expenditure was significantly higher than controls' and associated with catastrophic health expenditure and an income gap for one fifth and two thirds of cases respectively. Quality of life scores were lower for cases than controls overall and in each sub-category of quality of life, and cases were far less likely to have participated in productive work the previous day than controls. CONCLUSION: Adults with MSI in Myanmar who are not in receipt of rehabilitative services may be at increased risk of poverty and lower quality of life in relation to increased health needs and limited opportunities to participate in productive work. This study highlights the need for more comprehensive and appropriate support to persons with physical impairments in Myanmar.
