Digital Technology Use Among Older Adults With Vision Impairment

Digital Technology Use in US Community-Dwelling Seniors With and Without Homebound Status

OBJECTIVES

To examine (1) the prevalence of digital technology use, including information and communication technology devices, everyday technology use, and digital health technology use among community-dwelling older adults with or without homebound status and (2) the associations of digital technology use with homebound status.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

We used the 2022 National Health and Aging Trends Study (NHATS) data that included 5510 community-dwelling older adults.

METHODS

Digital technology use was assessed using self-reported outcomes of the technological environment component of the NHATS, including information and communication technology devices, everyday technology use, and digital health technology use. Homebound status was measured with 4 mobility-related questions regarding the frequency, independence, and difficulties of leaving home. Survey-weighted, binomial logistic regression was used to examine the associations of 17 technological-related outcomes and homebound status.

RESULTS

Overall, the prevalence of homebound older adults was 5.2% (95% CI, 4.4%-6.1%), representing an estimated 2,516,403 people. The prevalence of digital technology use outcomes varied according to homebound status. The prevalence of any technology used in homebound, semi-homebound, and non-homebound populations was 88.5%, 93.3%, and 98.5%, respectively. Compared with non-homebound older adults, semi-homebound older adults had lower odds of emailing (OR, 0.71; 95% CI, 0.53-0.94), using the internet for any other reason (OR, 0.70; 95% CI, 0.49-0.99), visiting medical providers (OR, 0.68; 95% CI, 0.48-0.95), and handling insurance (OR, 0.75; 95% CI, 0.56-0.99); homebound older adults had lower odds of using a phone (OR, 0.41; 95% CI, 0.28-0.59), using any everyday technology (OR, 0.58; 95% CI, 0.38-0.89), visiting medical providers (OR, 0.52; 95% CI, 0.35-0.76), and handling insurance (OR, 0.57; 95% CI, 0.38-0.86).

CONCLUSIONS AND IMPLICATIONS

Non-homebound older adults are more likely to use digital technology than those who are semi-homebound or homebound. Public health care providers should prioritize efforts to enhance digital inclusion to ensure that all older adults can benefit from the advantages of digital technology.

Prevalence of dry eye in people over 50 years old in Beichen district, Tianjin city: a cross-sectional population-based survey

BACKGROUND

A cross-sectional population-based survey in the Beichen district of Tianjin was conducted to estimate the prevalence of dry eye disease (DED) among the population over 50 years old with Dry Eye Workshop (DEWS) II and Chinese expert consensus (CEC) criteria.

METHODS

A total of 5791 subjects over 50 years old were enrolled. Ocular surface disease index (OSDI) questionnaire, lipid layer thickness (LLT), partial blink ratio (PBR), fluorescein tear film breakup time (FBUT), Schirmer I test (SIT), fluorescein staining, meibomian gland dropout, meibomian gland expression scores (MES) and quantity scores (MQS) was assessed. Additionally, basic information, weight, disease history, living habits, anxiety, and depression condition were collected.

RESULTS

According to the CEC, the prevalence of DED was 39.0%, whereas 44.0% based on DEWS II. The prevalence of DED increased with age and was substantially greater among women (41.1%, 95% CI, 39.5-42.6%) than males (35.1%, 95% CI, 33.1 -37.2%) (p < 0.001). Furthermore, the severity of DED was more severe in women (p = 0.006). The associated risk factors were age, female, depression, smoking, insomnia, and glaucoma. On the other hand, 53.6% of these populations were diagnosed as asymptomatic DED, and the morbidity was higher in males (p = 0.007).

CONCLUSIONS

The prevalence of DED in China was relatively high, which was associated with aging, female(sex), depression, smoking and sleep problems. Hence, it is crucial for clinicians and caregivers to be aware of the existence of asymptomatic DED within the susceptible population.
