Tea consumption, cardiovascular diseases risk factors, sleep and mental health status among diabetic women.

Abstract

Objectives: To examine the association between tea consumption, mental health and sleep status in female patients with type 2 diabetes.

Methods: This cross-sectional study was conducted on 230 women with type 2 diabetes. All participants completed a sociodemographic questionnaire, a physical activity record, and a food frequency questionnaire to determine dietary intake and tea consumption. To evaluate sleep status and mental health, the Pittsburgh Sleep Quality Index and Depression, Anxiety and Stress Scale were completed by participants, respectively. Anthropometric measures and biochemical assessments were also recorded.

Results: The mean age and BMI of participants was 59.9 ± 9.20 years and 29.31 ± 4.52 kg/m², respectively. There was a significant association between sleep duration at night and tertiles of tea intake (P = 0.006). Furthermore, we found a significant association between sleep latency and tertiles of tea intake (P = 0.042). There was a significant positive association between amounts of tea intake and sleep latency in both crude (B; 0.023; SE: 0.009; P-value: 0.015) and adjusted models (highly adjusted model: B; 0.024; SE: 0.009; P-value: 0.011) using linear regression. We found no evidence of an association between tea intakes and sleep status, depression symptoms, anxiety and stress.

Conclusions: We found evidence of a significant association between tea intakes, sleep duration, and sleep quality at night. However, there was no significant association between tea intake and mental health. Future studies evaluating this relationship should consider different types of tea, as well as caffeine and other bioactive components.
