The relationship between dietary patterns and insomnia in young women.

AIM: There is mounting evidence that eating habits affect sleeping patterns and their quality. The goal of this study was to evaluate the associations between major dietary patterns, identified using principal component analysis (PCA) and insomnia in young women. METHODS: The study subjects comprised 159 healthy young women aged 18-25 years. Neuropsychological assessment was performed using standard instruments, including a cognitive ability questionnaire (CAQ), depression and anxiety stress scales (DASS-21), insomnia severity index (ISI), Epworth sleepiness scale (ESS), and quality of life questionnaire (QLQ). Dietary patterns were obtained from a 65-item validated food frequency questionnaire (FFQ) in this study, using PCA. RESULTS: Two major dietary patterns were identified that were termed: "Traditional" and "Western." The Western pattern was characterized by a high intake of snacks, nuts, dairy products, tea, fast foods, chicken, and vegetable oils. Subjects with moderate/severe insomnia were found to have lower scores for total cognitive ability task, nocturnal sleep hours, and physical and mental health, but higher scores for depression, anxiety, stress, and daytime sleepiness compared to those without insomnia (p < 0.05). After adjustment for potential confounders, high adherence to the Western dietary pattern was associated with higher odds of insomnia (OR = 5.9; 95% confidence intervals: 1.9-18.7; p = 0.003). CONCLUSION: Our findings indicated adherence to Western pattern may increase the odds of insomnia. Prospective research is required to determine the feasibility of targeting dietary patterns to decrease the odds of insomnia.

Assessment of ideal cardiovascular health metrics in refugees, East of Iran.

BACKGROUND: In 2013, there was an estimation of greater than 4.5 million Afghan refugees who had migrated to the least developed countries. Over one million are legally registered in Iran. We assessed the heart health status as described by the American Heart Association (AHA) in the Afghan refugee populace. METHODS: This cross-sectional survey was carried out on 1,634 Afghan refugees, including 746 males (45.7%) and 888 females (54.3%), selected through a convenience sampling method in 2016. The American Heart Association's seven cardiovascular health metrics were evaluated to specify the status of heart health in Afghan refugees. Differences with age and sex were analyzed using the χ2 test. RESULTS: Only one (0.1%) participant met the ideal for all seven cardiovascular health metrics. No significant differences were found between women and men in meeting the ideal criteria for more than five cardiovascular health metrics. As age increased, the proportion of refugees who met the ideal for more than five cardiovascular health metrics declined. CONCLUSIONS: Refugees were not meeting the ideal cardiovascular health for some of the assessed metrics. Intervention to improve and monitor heart health in Afghan refugees is needed.
