| Summary: | Background: The EAT-Lancet Commission proposed a global reference diet to promote healthy diets within planetary boundaries. Recently, the Planetary Health Diet Index (PHDI) was proposed to evaluate the adherence to the EAT-Lancet diet, and it has been validated among European adolescents. However, studies evaluating the associations between the PHDI with health outcomes among adolescents are lacking. Thus, our aim was to assess the association between adherence to the EAT-Lancet diet—through the PHDI score—and cardiovascular health among European adolescents. Methods: Data from the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study were used. Usual dietary intake was assessed using two 24 h dietary recalls, and adherence to the EAT-Lancet diet was assessed using the PHDI, a 16-component index that ranges from 0 to 150 points. Cardiovascular health was assessed through the seven-component Ideal Cardiovascular Health (ICH) score, the seven components of which are as follows: never smoked, eutrophic body mass index, moderate to vigorous physical activity, healthy dietary pattern, low blood pressure, low fasting plasma glucose, and low total cholesterol. Total ICH scores were categorized into ideal (5–7) and non-ideal (0–4). Logistic regression models were fitted to evaluate the association between the PHDI and ICH, and the model was adjusted for potential confounders, including age, sex, socioeconomic disadvantage/vulnerability score, and total energy intake. Results: A 10-point increase in the PHDI was associated with a lower probability of a non-ideal ICH status (OR 0.84, [95% CI: 0.75, 0.94]) among European adolescents in the adjusted model. Furthermore, a 10-point increase in the PHDI was associated with a lower probability of high blood pressure (OR: 0.87 [0.79, 0.96]) and a lower probability of high blood cholesterol (OR: 0.88 [0.78, 0.99]). Discussion: In the HELENA study, we found that higher adherence to the EAT-Lancet reference diet was positively associated with better cardiovascular health among European adolescents. Furthermore, adolescents with a higher PHDI were less likely to have high blood pressure and cholesterol. |
