Factors Associated With Digital Capacity for Health Promotion Among Primary Care Workers: Cross-Sectional Survey Study.

Abstract

Background: Health education and promotion are recognized as effective strategies for fostering healthy ageing, reducing the disease burden, and addressing health inequalities, particularly when delivered through digital media. Primary care workers are often regarded as the key providers of these interventions. Despite the strong practical significance and substantial individual demand, the use of digital media for delivering health promotion practices was not widespread in China. One of the main challenges identified is the providers' inadequate capacities. However, little is known about the digital capacity for health promotion among primary care workers.

Objective: This study aimed to investigate the levels of digital capacity for health promotion and its associated factors among community health workers.

Methods: A total of 1346 community health workers were recruited from across 47 communities in Shanghai, China, through cluster-stratified random sampling. The digital capacity for health promotion was measured using the revised version of the Digital Capabilities Framework. Web-based questionnaires were distributed to collect data from March 20 to March 29, 2024. Data were analyzed using descriptive statistics, independent t tests, one-way ANOVA, and linear hierarchical regression using Stata MP (version 17.0; StataCorp).

Results: We included 1199 participants. Among them, 47.5% (570/1199) had high digital media use for more than 19.6 hours per week, whereas 31.8% (381/1199) demonstrated high digital media trust. The average level of digital capacity for health promotion was 16.71 (SD 2.94) out of 25 points. Demographics, digital media usage-related characteristics, perceived usefulness and usability, attitudes, and behaviors were significant predictors of the capacities, explaining 44.4% of the total variance. Master's degree or above (β=.077; P=.013), perceived usability (β=.235; P<.001), attitudes toward digital media health promotion (β=.095; P=.002), and past digital media health promotion practices (β=.377; P<.001) had significantly positive associations with digital capacities for health promotion. However, senior (β=-.076; P=.008) or median (β=-.074; P=.01) titles had a significant negative association with capacity levels.

Conclusions: A digitally capable workforce is required for primary health care systems to take full advantage of digital media health promotion. Therefore, solutions are necessary to achieve enhanced capacities among health professionals, including public health policy making, community empowerment, and individual practices.
