In the journey towards a healthier and longer life, a recent study has highlighted the importance of maintaining a healthy lifestyle, especially for postmenopausal women. The research, led by Rita Peila and her team, focused on the concept of multimorbidity, which refers to the presence of two or more chronic health conditions in an individual. As we age, the likelihood of developing multiple chronic conditions increases, making this a critical area of study for longevity.
The researchers developed a Healthy Lifestyle Index (HLI), which combined indicators of diet quality, smoking status, alcohol intake, physical activity, sleep duration, and body mass index (BMI). They then investigated the relationship between this index and the risk of multimorbidity among 62,037 postmenopausal women aged 50-79 years. The results were striking. Over an average follow-up period of 16.3 years, 5,656 women developed multimorbidity. However, women with higher HLI scores, indicating a healthier lifestyle, had a significantly lower risk of developing multimorbidity.
In conclusion, the study underscores the power of a healthy lifestyle in reducing the risk of multiple chronic conditions among postmenopausal women. It suggests that by maintaining a balanced diet, staying physically active, getting enough sleep, and avoiding harmful habits like smoking and excessive alcohol consumption, women can significantly improve their health and longevity prospects.

Background: Multimorbidity, defined as the presence of two or more chronic health conditions, is increasingly common among older adults. The combination of lifestyle characteristics such as diet quality, smoking status, alcohol intake, physical activity, sleep duration, and body fat as assessed by body mass index (BMI) or waist circumference, and risk of multimorbidity is not well understood.
Objective: We investigated the association between the healthy lifestyle index (HLI), generated by combining indicators of diet quality, smoking, alcohol, physical activity, sleep amount, and BMI, and risk of multimorbidity, a composite outcome that included cardiovascular disease, diabetes, cancer and fracture.
Methods: We studied 62,037 postmenopausal women ages 50-79 years at enrollment in the Women's Health Initiative, with no reported history of cardiovascular disease, diabetes, cancer or fracture at baseline. Lifestyle characteristics measured at baseline were categorized and a score (0-4) was assigned to each category. The combined HLI (0-24) was grouped into quintiles, with higher quintiles indicating a healthier lifestyle. Multivariable adjusted estimates of hazard ratios (HR) and 95% confidence intervals (95%CI) for the risk of developing multimorbidity were obtained using Cox proportional hazard models.
Results: Over an average follow-up period of 16.3 years, 5,656 women developed multimorbidity. There was an inverse association between the HLI levels and risk of multimorbidity (compared to the HLI_1 stquintile: HR_2 ndquintile=0.81 95%CI 0.74-0.83, HR_3 rdquintile=0.77 95%CI 0.71-0.83, HR_4 thquintile=0.70 95%CI 0.64-0.76, and HR_5 thquintile=0.60 95%CI 0.54-0.66; p-trend<0.001). Similar associations were observed after stratification by age or BMI categories.
Conclusions: Among postmenopausal women, higher levels of the HLI were associated with a reduced risk of developing multimorbidity.
