To investigate the relationship between two distinct measures of disability: self-reported functional limitations and objectively-screened clinical impairments. We undertook an all age population-based survey of disability in two areas: North-West Cameroon (August/October 2013) and Telangana State, India (Feb/April 2014). Participants were selected for inclusion via two-stage cluster randomised sampling (probability proportionate to size cluster selection and compact segment sampling within clusters). Disability was defined as the presence of self-reported functional limitations across eight domains, or presence of moderate or greater clinical impairments. Clinical impairment screening comprised of visual acuity testing for vision impairment, pure tone audiometry for hearing impairment, musculoskeletal functioning assessment for musculoskeletal impairment, reported seizure history for epilepsy and reported symptoms of clinical depression (depression adults only). Information was collected using structured questionnaires, observations and examinations. Self-reported disability prevalence was 5.9% (95% CI 4.7–7.4) and 7.5% (5.9–9.4) in Cameroon and India respectively. The prevalence of moderate or greater clinical impairments in the same populations were 8.4% (7.5–9.4) in Cameroon and 10.5% (9.4–11.7) in India. Overall disability prevalence (self-report and/or screened positive to a moderate or greater clinical impairment) was 10.5% in Cameroon and 12.2% in India, with limited overlap between the sub-populations identified using the two types of tools. 33% of participants in Cameroon identified to have a disability, and 45% in India, both reported functional limitations and screened positive to objectively-screened impairments, whilst the remainder were identified via one or other tool only. A large proportion of people with moderate or severe clinical impairments did not self-report functional difficulties despite reporting participation restrictions. Tools to assess reported functional limitation alone are insufficient to identify all persons with participation restrictions and moderate or severe clinical impairments. A self-reported functional limitation tool followed by clinical screening of all those who report any level of difficulty would identify 94% of people with disabilities in Cameroon and 95% in India, meeting the study criteria.

Adequate access to water, sanitation and hygiene (WASH) is imperative for health and wellbeing, yet people with disabilities, people with incontinence and people who menstruate often experience unmet WASH requirements. In 2019 we completed a mixed-methods study in two provinces of Vanuatu, (SANMA and TORBA). The study comprised 1) a population-based disability survey using the Washington Group Short-Set 2) a nested case-control study to explore associations between WASH, disability and gender, and 3) an in-depth qualitative assessment of the experiences of WASH users with additional requirements: people with and without disabilities who menstruate, or experience incontinence. 11,446 households (response rate 85%) were enrolled into the survey. All-age disability prevalence across the two provinces was 2.6% (95% Confidence Interval 2.5–2.8), increasing with age. 814 people with, and 702 people without disabilities participated in the case-control study. People with disabilities were statistically more likely to experience barriers in seven of eight intra-household indicators. WASH-related stigma, reliance on informal caregivers, and under-resourcing of WASH personnel were critical issues for people who menstruate or experience incontinence. People with disabilities, people with incontinence and people who menstruate in Northern Vanuatu face continued challenges in accessing safe, affordable and appropriate WASH that meets their requirements. Outputs from this study have supported progression towards gender and disability-inclusive WASH programming in the area and highlighted the value of mixed-methods research. The research was funded by the Australian Government's Water for Women fund and donations from the Australian public.

Purpose: To assess the association between disability and serious health problems, and the access and uptake of health and rehabilitation services in Cameroon and India. Methods: We undertook a population-based case–control study, nested within a survey in Fundong Health District, North West Cameroon (August–October 2013) and in Mahbubnagar District, Telangana State, India (February–April 2014). Disability was defined as the presence of self-reported difficulties in functioning or clinical impairments. One control without disability was selected per case, matched by age, gender and cluster. Information was collected using structured questionnaires on: socioeconomic status, health, access to health services and rehabilitation. Results: Cases with disability were significantly more likely to report a serious health problem in the last year compared to controls in both India (OR = 3.2, 95% CI 2.1–4.8) and Cameroon (OR = 1.9, 1.4–2.7). The vast majority of people sought care when seriously ill, and this did not vary between cases and controls. Awareness and use of rehabilitation services was extremely low in both Cameroon and India. Conclusions: Further focus is needed to improve awareness of rehabilitation services among people with disabilities in India and Cameroon to ensure that their rights are fulfilled and to achieve the goal of Universal Health Coverage.

As countries progress through economic and demographic transition, chronic non-communicable diseases (NCDs) overtake a previous burden of infectious diseases. We investigated the prevalence of hypertension, diabetes, obesity, and multimorbidity in older adults in The Gambia. We embedded a survey on NCDs into the nationally representative 2019 Gambia National Eye Health Survey of adults aged 35 years or older. We measured anthropometrics, capillary blood glucose, and blood pressure together with sociodemographic information, personal and family health history, and information on smoking and alcohol consumption. Hypertension was defined as systolic blood pressure of 140 mmHg or more, diastolic blood pressure of 90 mmHg or more, or receiving treatment for hypertension. Diabetes was defined as fasting capillary blood glucose of 7 mmol/L or more, random blood glucose of 11·1mmol/L or more, or previous diagnosis or treatment for diabetes. Overweight was defined as BMI of 25-29·9 kg/m2 and obesity as 30 kg/m2 or more. Multimorbidity was defined as the coexistence of two or more conditions. We calculated weighted crude and adjusted estimates for each outcome by sex, residence, and selected sociodemographic factors. We analysed data from 9188 participants (5039 [54·8%] from urban areas, 6478 [70·5%] women). The prevalence of hypertension was 47·0%; 2259 (49·3%) women, 2052 (44·7%) men. The prevalence increased with age, increasing from 30% in those aged 35-45 years to over 75% in those aged 75 years and older. Overweight and obesity increased the odds of hypertension, and underweight reduced the odds. The prevalence of diabetes was 6·3% (322 [7·0%] women, 255 [5·6%] men), increasing from 3·8% in those aged 35-44 years to 9·1% in those aged 65-75 years, and then declining. Diabetes was much more common among urban residents, especially in women (peaking at 13% by age 65 years). Diabetes was strongly associated with BMI and wealth index. The prevalence of obesity was 12·0% and was notably higher in women than men (880 [20·2%] vs 170 [3·9%]). Multimorbidity was present in 932 (10·7%), and was more common in women than men (694 [15·9] vs 238 [5·5]). The prevalence of smoking was 9·7%; 5 (0·1%) women, 889 (19·3%) men. Alcohol consumption in the past year was negligible. We have documented high levels of NCDs and associated risk factors in Gambian adults. This presents a major stress on the country's fragile health system that requires an urgent, concerted, and targeted mutisectoral strategy.

Background: Article 25 of the UNCRPD stipulates the right of people with disabilities to the highest attainable standard of health, and the timely uptake of appropriate health and rehabilitation services. This study seeks to explore the factors which influence access to health care among adults with disabilities in Cameroon and India. Methods: A total of 61 semi-structured interviews were conducted with a purposive sample of adults with vision, hearing or musculoskeletal impairments, using data from an earlier cross-sectional disability survey. In addition, 30 key informants were interviewed to provide contextual information about the local services and context. Results: Key themes included individual-level factors, understanding and beliefs about an impairment, and the nature of the impairment and interaction with environmental factors. At the community and household level, key themes were family dynamics and attitudes, economic factors, social inclusion and community participation. Intersectionality with gender and age were cross-cutting themes. Trust and acceptability of health service providers in India and poor understanding of referral processes in both countries were key service-level themes. Conclusions: The interaction of environmental and personal factors with the impairment and their levels of participation and inclusion in community structures, all contributed to the take up of services. This study illustrated the need for a multi-faceted response to improve access to health services for people with disabilities.
