Implementing an inclusive digital health ecosystem for healthy aging: a case study on project SingaporeWALK.

Objective: To pilot a digital health technologies ecosystem known as project SingaporeWALK (earables and pps for ommunity iving and nowledge) that build capacity in older adults, senior center managers, health coaches, and caregivers in using health technologies (eg, wearables, apps, exergames) collaboratively in a gamified way for active aging.

Materials And Methods: The SingaporeWALK ecosystem was set up through 3 initiatives: (1) co-developing technologies with stakeholders; (2) raising digital literacy and capacity building; and (3) cultivating community and intergenerational bonding for active aging through gamified technology use.

Results: Significant improvements in older adults' self-reported physical and mental health post-intervention were observed.

Soil fungal networks exhibit sparser interactions than bacterial networks in diseased banana plantations.

Unlabelled: Soil microorganisms play a crucial role in suppressing soil-borne diseases. Although the composition of microbial communities in healthy versus diseased soils is somewhat understood, the interplay between microbial interactions and disease incidence remains unclear. This study used 16S rRNA and fungal internal transcribed spacer (ITS) sequencing to investigate the bacterial and fungal community composition in three soil types: forest soil (Z), soil from healthy banana plantations (H), and soil from diseased banana plantations (D).

Single or Multiplayer Mode? Examining the Effects of Exergames in Improving Physical Health and Well-Being Among Older Adults.

This study assesses the impact of single-player and multiplayer exergaming modes on improving exercise intentions, reduction of fear of falling, and emotional well-being among older adults, primarily from low socioeconomic status (SES) backgrounds-a group often underrepresented in exergame research. We engaged 48 participants, primarily from low-SES communities in Singapore for a 4-week community-based exergaming intervention. Participants were divided into four groups as follows: (1) conventional exercise alone, (2) exergames alone, (3) exergames with a health coach, and (4) exergames with a peer.

Examining health apps and wearable use in improving physical and mental well-being across U.S., China, and Singapore.

Health apps and wearables are touted to improve physical health and mental well-being. However, it is unclear from existing research the extent to which these health technologies are efficacious in improving physical and mental well-being at a population level, particularly for the underserved groups from the perspective of health equity and social determinants. Also, it is unclear if the relationship between health apps and wearables use and physical and mental well-being differs across individualistic, collectivistic, and a mix of individual-collectivistic cultures.
