AI Article Synopsis
- Obesity and age are key risk factors for sleep apnoea syndrome (SAS), but the impact of body mass index (BMI) on sleep quality in healthy older adults remains uncertain.
- A study involving 32 active Japanese adults aged 83-95 explored the relationship between sleep parameters and BMI, revealing a high prevalence of moderate or severe SAS in both low and high BMI groups.
- Results showed that in the high-BMI group, increased apnoea-hypopnoea index (AHI) correlated negatively with sleep depth, while in the low-BMI group, the number of awakenings and age linked positively with AHI, suggesting that SAS can affect older adults regardless of BMI.
Article Abstract
Obesity and ageing are the most important risk factors for sleep apnoea syndrome (SAS); however, the role of body mass index (BMI) on sleep status in healthy older adults is unclear. To explore sleep parameters according to BMI among active older adults, we cross-sectionally examined the relationship between sleep-related parameters and BMI in 32 Japanese adults aged from 83 to 95 years without long-term care who were unaware of having SAS. Correlation and linear regression analyses were performed. Moderate or severe SAS prevalence was high in both those with low (68.8%) and high (68.8%) BMI. A higher increase in apnoea-hypopnoea index (AHI) was negatively correlated with sleep depth in the high-BMI group. In the low-BMI group, the number of awakenings and age were positively correlated with AHI. Older adults may have SAS regardless of their BMI, and the sleep status of patients with SAS may vary by BMI.
