Reducing noncommunicable disease risk in midlife adults using eHealth: The GroWell for Health Program feasibility study

Abstract

BackgroundMidlife adults are at increased risk of noncommunicable disease due to the lifetime cumulative effect of unhealthy behaviours and increased prevalence of overweight and obesity. AimThis study evaluates preliminary effectiveness and feasibility of an eHealth intervention (GroWell for Health Program) designed for primary prevention of modifiable risk factors in midlife adults. MethodsThe sample comprised community dwelling adults 40 to 59 years, able to read English with access to a personal computer/tablet. Following consent, participants were randomly allocated to a structured 8-week intervention including an eBook (Arm A) or an eBook plus nurse coaching (Arm B). Outcome measures include self-report physical activity, diet, stage of change; anthropometric measures; and feasibility. FindingsOverall 40 people consented to participate in the study. The majority were female (89.2%) with a mean age of 50.6 (SD = 6.3) years. Significant within groups change over time was observed in Arm A for physical activity, fruit, vegetable intake and exercise stage of change; and daily vegetable and fruit intake, fruit, and exercise stage of change than in Arm B. DiscussionThe direction of change in outcomes suggests the intervention content and structure is likely to be effective in supporting behaviour change in midlife adults. Health coaching from nurses improved retention, although for motivated participants completing the program independently using the eBook is a cost-effective option. ConclusionPromising results suggest the nurse delivered eHealth intervention is feasible and likely be effective in addressing modifiable risk factors for NCD in midlife adults.
