Introduction:One of the basic needs of human is sleep. Research has shown that poor quality of sleep is the 3rd problem in the elderly people, being one of their most common complaints and reason to refer to doctors. The objective of this survey is to study the frequency of sleep disorder and how to deal with it. Materials and Methods:This cross-sectional study was conducted on 360 people aged 60 or older, using a self-made structured questionnaire and interview. The data entered into SPSS, version 11.5. Descriptive and analytical statistics such as Chi square and Fisher exact tests were used to analyze the data. Results:In this survey, the mean age of the subjects was 67.7±7.33; 70.3% suffered sleep disorder and 81.81% of them had primary insomnia. Sleep disorder showed a significant relationship whit marital status, gender, residency, education and employment. In this survey, 94.5% (239 men) that had sleep disorder used at least one of the non-pharmacological methods and7.5 percent of them used pharmacological methods to cope with sleep disorders. Conclusion:Considering the fact that most of the elderly people used one of the non-pharmacological methods to cope with sleep disorders but still the prevalence of sleep disorders is high, we can conclude that it can be the result of their inappropriate use. Therefore, we recommend that the health care staff should focus on educating the elderly people on how to use the nonpharmacological methods.

The rising prevalence of metabolic syndrome and its serious side-effects have drawn the attention of researchers to the importance of adherence to self-care behavior and recognizing its related factors such as patients' health literacy. Objective: This study aimed at determining the relationship of health literacy with adherence to self-care behaviors in patients with metabolic syndrome living in Rasht City, Iran, in 2016. Materials and Methods: This analytical cross-sectional study has been conducted on 184 patients with metabolic syndrome who referred to selective specialist clinics of Rasht. The subjects were recruited by consecutive sampling method. The study data were collected with a three-part research instrument consisting of a disease-related and demographic questionnaire, hypertension self-care activity level effects, and health literacy for Iranian adults. The obtained data were analyzed by descriptive and inferential statistics (The Chisquare test and multiple logistic regression). Results: The findings have shown that a high percentage of samples have adhered to not smoking (90.2%) and avoidance of alcohol consumption (98.9%), and a low percentage to diet (21.2%) and physical exercise (18.5%). Most samples had adequate health literacy (44.6%). Their total health literacy had only a significant relationship with self-care behaviors related to losing weight (P=0.0001). On the whole, regression test analyses confirmed the predicting ability of decision making and health literacy behaviors in adherence to medication (β=0.006; 95%CI=1.269-2.948; P=0.001), diet (β=1.525; 95%CI=2.108-10.006; P=0.001), smoking (β=1.244; 95%CI=1.814-6.632; P=0.001), and weight control (β=0.931; 95%CI=1.458-4.415; P=0.001). Conclusion: The findings of the research call for further attention to health literacy promotion, especially in decision making and behavior dimension in patients with metabolic syndrome.
