Relationship between lifestyle factors, medical conditions, and sleep quality in women

A descriptive approach was used to elicit lifestyle, socio-demographic and medical factors that are closely related to very poor subjective sleep quality in women. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) in a sample of 678 women aged 25--58 years old who participated in the POUCHmoms (Pregnancy Outcomes and Community Health Moms) study. Overall, medical conditions were found to be most strongly related to sleep quality. Women who had Asthma and taking medication had an aOR (adjusted odds ratio) of 2.3 (95% CI = 1.3, 3.9) compared to those without the condition, while the odds was the same for both women with the condition but not taking medication and those without the condition aOR=1.1 (95% CI = 0.5, 2.2). Women who had Migraine, taking medication and not had aOR=1.8 (95% CI = 1.0, 3.4) and aOR = 1.9 (95% CI = 1.1, 2.8) respectively. For women with other conditions (Gastro-intestinal problems, Auto-Immune disorders and non-Rheumatoid Arthritis) and taking medication the odds was aOR=2.2 (95% CI = 1.4, 3.5), while for both women with any of the conditions not taking medication, and those without the conditions, the odds were the same aOR = 1.0 (95% CI = 0.5, 1.7). Also, current smokers had increased odds of having very poor sleep quality aOR = 1.8 (95% CI = 1.2, 2.8) compared to non-smokers while the odds was the same for both former and non-smokers aOR = 1.4 (95% CI = 0.8, 2.4). Medicaid users/uninsured women had an increased odds of having very poor sleep quality compared to private insured aOR = 2.0 (95% CI = 1.3, 2.9). Finally tea consumption (cups/day) was also strongly associated with very poor sleep quality aOR=1.1 (95% CI = 1.0, 1.3).
