Effects of lifestyles and the Mediterranean diet on elderly people’s quality of life according to gender / Efectos de los estilos de vida y la dieta mediterránea en la calidad de vida en personas mayores en función del género

Abstract Health-related quality of life (HRQoL) has been associated with certain eating habits, such as the Mediterranean diet (MD) and lifestyles. However, the specific role of gender in this association is not yet known. The objective of this study was to analyse the relationship between the consumption of the MD essential foods and lifestyle (tobacco and alcohol consumption and exercise) with the HRQoL of 340 elderly people aged over 60 living in the Spanish Mediterranean area. The results show a better HRQoL in males. Compared to females, the lifestyles of males include a moderate consumption of alcohol and tobacco in addition to a greater frequency of physical activity. The predictive models of HRQoL were also different between males and females, as the influence of lifestyles and MD were greater in males. These results are clinically useful for the designing of programmes that promote successful ageing as they can be specified for sex.
