The relationship between adherence to a Mediterranean diet (MedDiet) and health-related quality of life (HRQoL) is unclear, particularly in vulnerable older adults. This cross-sectional analysis explored the association between adherence to a MedDiet and subscales of HRQoL in two independent cohorts of overweight and obese middle-aged to older adults with and without type 2 diabetes mellitus (T2DM). Both cohorts were community-dwelling (T2DM aged ≥50 years; non-T2DM aged ≥60 years) with a BMI ≥25kg/m2. Adherence to a MedDiet was assessed using the Mediterranean Diet Adherence Screener (MEDAS), and HRQoL was determined using the 36-item short-form health survey (SF-36). Multiple regression analysis was used to examine the association between adherence to a MedDiet and HRQoL subscales. A total of n = 152 middle-aged to older adults were included (T2DM: n = 87, 71.2 ± 8.2 years, BMI: 29.5 ± 5.9kg/m2; non-T2DM: n = 65, 68.7 ± 5.6 years, BMI: 33.7 ± 4.9kg/m2). Mean adherence scores for the entire cohort were 5.3 ± 2.2 (T2DM cohort: 5.6 ± 2.3; non-T2DM cohort: 4.9 ± 2.0). In the adjusted model, using pooled data from both study cohorts, adherence to a MedDiet was significantly associated with the general health subscale of HRQoL (β = 0.223; 95% CI: 0.006-0.044; P = 0.001). Similar findings were also observed in the T2DM cohort (β = 0.280; 95% CI: 0.007-0.054; P = 0.001). However, no additional significant associations between adherence to a MedDiet and HRQoL subscales were observed. We showed that adherence to a MedDiet was positively associated with the general health subscale of HRQoL in middle-aged to older adults with T2DM. However, larger longitudinal data in older adults with a wider range of adherence scores, particularly higher adherence, is required to better understand the direction of this relationship.
