Social media use and vision impairment in adults between the ages of 18 and 35 years in India.

SIGNIFICANCE: Social media is used by >4.48 billion people worldwide. Despite its popularity, vision-impaired individuals struggle to use social media given visual inaccessibility of content and lack of access to Internet/Wireless-Fidelity-enabled devices. Our study explores visually impaired adult's use of social media in comparison to a control group. PURPOSE: This study aimed to report the demographic profile and patterns of social media use among adults with vision impairment (VI) aged 18 to 35 years and compare it with an age-matched normally sighted group in India. In addition, we explored barriers to use of social media among adults with VI. METHODS: Vision-impaired and normally sighted adults (controls) aged 18 to 35 years at L V Prasad Eye Institute, Hyderabad, India, answered a questionnaire about social media use (e.g., platform used). RESULTS: Four hundred twenty-two individuals (201 VI, 221 controls) participated. Normally sighted adults (98%) used social media more than the VI group (81%; p<0.001). Vision-impaired users were predominantly male (85%) and unemployed (57%; p<0.00001 for both). There was no significant difference in educational level between groups (p=0.17). Smartphones were the most popular device used (VI, 161 [99%]; control, 206 [95%]), with tablet PC/iPad being the least popular (VI, 5 [3%]; control, 12 [6%]). Adults with VI and controls commonly used WhatsApp as communication platforms, and Facebook and Twitter as networking platforms. Approximately one-third of individuals across both social media user groups reported barriers to use (VI, 48 [30%]; control, 74 [34%]; p<0.001). Vision-impaired individuals cited accessibility issues of having to rely on audio over vision to navigate social media, whereas controls reported having to share a phone. CONCLUSIONS: The proportion of social media usage among VI adults is high (81%) and is substantially higher than the 33% reported in the general Indian population. Vision-impaired adults who used social media were male with moderate VI and were less likely to be employed compared with controls.

Young adults with vision impairment in India: Loneliness and social networks.

PURPOSE: To examine the prevalence of loneliness and associated factors in young adults with vision impairment (VI), including quality of life (QoL) in India. METHODS: Two hundred and three VI young adults (18-35 years) and 219 age-matched non-VI (controls) adults completed the loneliness scale, WHOQOL-BREF, Social Network Index (SNI) (network diversity, people in network size and number of embedded network subscales) and questions regarding sociodemographic characteristics and independent mobility. Rasch analysis was used to validate the questionnaires and interval-level scores were generated. Generalised linear models were used to estimate independent associations of sociodemographic factors, VI characteristics, social networks and QoL with loneliness. RESULTS: The prevalence of moderate and severe loneliness in the VI group was 10% (95% CI: 6.5, 15.4) and 4.4% (95% CI: 2.0, 8.2), respectively, and higher than that of controls. The VI group had a worse loneliness score than controls (-1.66 ± 2.25 vs. -2.13 ± 1.85 logits; p = 0.03). Those with ≤12 years and >12 years of education had loneliness scores of -1.58 ± 2.45 and -1.82 ± 1.99 logits, respectively (p = 0.01). Compared with controls, the VI group reported fewer extended family members, neighbours and friends leading to significantly smaller networks and network diversity (all p < 0.001). Loneliness scores demonstrated a significant correlation with only two SNI subscales for both groups: people in network size (r = -0.28 for VI; r = -0.30 for non-VI; p < 0.001 for both) and number of embedded networks (r = -0.22 for VI; r = -0.21 for non-VI; p = 0.002 for both). Both education (ß = 0.45; p = 0.04) and QoL (ß = -0.27, p = 0.02) were predictors of loneliness. CONCLUSIONS: Loneliness was commonly experienced by young VI adults and was higher among those with lower levels of education. Loneliness decreased with the presence of a larger number of people in network, suggesting that interventions to increase social activity and participation may be valuable in young VI adults.

Barriers and enablers to medication adherence in glaucoma: A systematic review of modifiable factors using the Theoretical Domains Framework.

PURPOSE: Nonadherence to medication reduces treatment effectiveness, and in chronic conditions it can significantly reduce health outcomes. In glaucoma, suboptimal adherence can lead to sight loss, which places a greater financial burden on society and reduces patients' quality of life. Interventions to improve adherence have so far had limited success and lack robust theoretical underpinnings. A better understanding of the determinants of medication adherence behaviour is needed in order to develop interventions that can target these factors more effectively. This systematic review aims to identify modifiable barriers and enablers to glaucoma medication adherence and identify factors most likely to influence adherence behaviour. RECENT FINDINGS: We searched CINAHL, MEDLINE, PsycINFO, EMBASE, the Cochrane Library and sources of grey literature up to August 2022 for studies reporting determinants of glaucoma medication adherence. Data describing modifiable barriers/enablers to adherence were extracted and analysed using the Theoretical Domains Framework (TDF), a behavioural framework consisting of 14 domains representing theoretical factors that most likely influence behaviour. Data were deductively coded into one of the TDF domains and inductively analysed to generate themes. Key behavioural domains influencing medication adherence were identified by frequency of study coding, level of elaboration and expressed importance. Eighty-three studies were included in the final synthesis. Four key domains influencing glaucoma medication adherence were identified: 'Environmental Context and Resources', 'Knowledge', 'Skills' and 'Memory, Attention and decision processes'. Frequently reported barriers included complex eyedrop regimens, lack of patient understanding of their condition, forgetfulness and difficulties administering eyedrops. Whereas simplified treatments, knowledgeable educated patients and good patient-practitioner relationships were enablers to adherence. SUMMARY: We identified multiple barriers and enablers affecting glaucoma medication adherence. Four theoretical domains were found to be key in influencing adherence behaviour. These findings can be used to underpin the development of behaviour change interventions that aim to improve medication adherence.
