Telehealth dietary intervention enhances diet quality

6 months ago

Dietary interventions targeting whole foods or dietary patterns delivered through telehealth can improve diet quality, fruit and vegetable intake, and dietary sodium intake, according to the results of a systematic review and meta-analysis.

Such interventions, when applicable, should be incorporated into healthcare services for people with chronic conditions, researchers said, adding that telehealth intervention could overcome patient-centred barriers to accessing face-to-face programmes and provide feasible delivery methods, accessible regardless of geographic location.

To assess the effectiveness of telehealth dietary interventions at facilitating dietary change in chronic disease, a structured systematic search was conducted for all randomized controlled trials (n=25) evaluating multifactorial dietary interventions in adults with chronic disease that provided diet education in an intervention longer than 4 weeks.

Researchers performed meta-analyses that used the random-effects model on diet quality, dietary adherence, and intakes of fruit and vegetables, sodium, energy and dietary fat. The included trials involved a total of 7,384 participants.

Telehealth dietary intervention improved diet quality (standardized mean difference [SMD], 0.22; 95 percent CI, 0.09 to 0.34; p=0.0007), fruit and vegetable intake (MD, 1.04 servings/day; 0.46 to 1.62; p=0.0004), and dietary sodium intake (SMD, –0.39; –0.58 to –0.20; p=0.0001).

On the other hand, telehealth intervention did not improve single nutrients (total fat and energy consumption).

However, important clinical outcomes were improved after a telehealth intervention. These outcomes included systolic blood pressure (MD, –2.97 mm Hg; –5.72 to –0.22 mm Hg; p=0.05), total cholesterol (MD, –0.08 mmol/L; –0.16 to –0.00; p=0.04), triglycerides (MD, –0.10 mmol/L; –0.19 to –0.01; p=0.04), weight (MD, –0.80 kg; –1.61 to 0; p=0.05) and waist circumference (MD, –2.08 cm; –3.97 to –0.20; p=0.03).

“The long-term management of chronic disease requires the adoption of complex dietary recommendations, which can be facilitated by regular coaching to support behavioral changes,” researchers said.
