Sleep duration and quality are associated with health-related quality of life in adults aged 60 years and older.

BACKGROUND: The current study aimed to determine the association between sleep duration and quality with health-related quality of life (HRQoL) among the Iranian older persons. METHODS: This study was conducted on a representative sample of 3452 Iranian older people (≥ 60 years) who participated in the Iranian Longitudinal Study on Ageing (IRLSA) launched in Neyshabur (Razavi Khorasan province, northeastern Iran). The Persian versions of 12-Item Short Form Survey (SF-12) and Pittsburgh Sleep Quality Index (PSQI) were utilized to measure the level of HRQoL and the level of sleep duration and quality, respectively. Multiple linear regression model was performed to analyze the data and clarify the independent association of sleep duration and quality with HRQoL. RESULTS: More than half of the study population (52.4%) suffered from poor sleep quality. 57.3% and 3.9% of individuals were short sleepers (< 7 h) and long sleepers (equal or more than 9 h), respectively. The total score of HRQoL was achieved 65.87 ± 20.55. After adjusting the covariates, the results indicated that short sleep duration was negatively associated with HRQoL (P < 0.05), whereas no significant associations were found between long sleep duration and HRQoL (P > 0.05). Interestingly, the results of multiple linear regression model revealed a significant negative association between poor sleep quality and HRQoL (P < 0.001). CONCLUSION: The current study confirmed that short sleep duration and poor sleep quality were independently associated with lower HRQoL in the older persons. Therefore, interventional courses should be planned to enrich sleep-related healthcare and general HRQoL in the older persons.

Is poor sleep quality associated with lipid profile in elderly population? Finding from Iranian Longitudinal Study on Ageing.

BACKGROUND: Abnormal lipid profile as one of reversible cardiovascular disease risk factors might be affected by poor sleep quality. AIM: This study aimed to assess the association between poor sleep quality and serum concentration of lipid profile in Iranian elderly population. METHODS: The study was performed on a representative sample of 3452 Iranian older people (≥60 years) who contributed in the Iranian Longitudinal Study on Ageing (IRLSA). Sleep quality was measured through the validated Persian version of Pittsburgh Sleep Quality Index (PSQI). Fasting blood samples were collected from the participants to measure plasma levels lipid profile. We used multiple linear regression model to evaluate the independent association of poor sleep quality with lipid profile. RESULTS: The mean age of participants was 68.0±6.7 years and 52.5% of them were male. In total, 52.4% of study population reported poor sleep quality (PSQI>5). Mean serum concentration of triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) was 143.2±74.2 mg/dl, 195.6±43.2 mg/dl, 112.9±31.0 mg/dl, and 57.3±12.4 mg/dl, respectively. Poor sleep quality was significantly associated with serum levels of TG (ß=17.85; P=0.006), LDL-C (ß=5.45; P=0.039) and HDL-C (ß=-2.13; P=0.039) after adjusting for studied covariates. CONCLUSION: Our study illustrates that poor sleep quality is a risk factor for poorer lipid profile. Therefore, early behavioral or pharmacological interventions that improve sleep quality are necessary to modify lipid profile in elderly population.

Water Pipe Smoking Reduction in the Male Adolescent Students: An Educational Intervention Using Multi-Theory Model.

BACKGROUND: Water pipe smoking (WPS) has increased and is becoming a major leisure pastime among young people in Iran. The aim of this study was to determine of efficacy of an educational intervention based on Multi-Theory Model (MTM) to reduce WPS in the male adolescent students in Iran. STUDY DESIGN: A randomized controlled trial. METHODS: Overall, 94 male adolescent students (grades 10, 11) smoked water pipe (WP) in the past month (current WP smokers) were selected, allocated randomly in two groups (47 students in intervention group and 47 students in control group), in two different schools in 2018 in Hamadan City, western Iran. Data were collected utilizing a valid and reliable questionnaire based on MTM constructs and demographic variables. Educational intervention was designed in five 45-min sessions. Two groups were followed-up three-months after completion of intervention. The collected data were analyzed using SPSS 22 software through Chi-square test, independent-sample t-test, paired-samples t-test, and Friedman test. RESULTS: There were significant differences between the mean score of participatory dialogue, behavioral confidence, emotional transformation and practice for change in the intervention group compared with the control group after the intervention (P<0.001). In addition, significant reductions in the frequency of WPS (from 14.9% to 4.3%) were observed in the intervention group compared to the control group (P<0.001). CONCLUSION: The developed educational intervention based on MTM constructs was efficacious and can be replicated for effectiveness studies to reduce WPS in the male adolescent students in Iran.

Male students' experiences on predictors of waterpipe smoking reduction: A qualitative study in Iran.

INTRODUCTION: In recent years, waterpipe smoking (WPS) has increased among adolescents in Iran. This study aimed to explain the experiences of high school students in Iran on predictors of WPS reduction based on a multi-theory model (MTM) of health behaviour change. METHODS: This study was a qualitative study of directed content analysis that was conducted in high school male students in Hamadan, Iran, in 2017. In this study, 34 students who had smoked waterpipe (WP) in the last month were recruited through snowball sampling that was continued until data saturation. The data were collected through semi-structured, individual interviews and were then analyzed using directed qualitative content analysis. RESULTS: The data analysis resulted in the extraction of 104 final codes around the six themes of predetermined MTM constructs consisting of participatory dialogue, behavioural confidence, changes in the physical environment, emotional transformation, practice for change, and changes in the social environment. The findings of this study showed that this model has the potential to explain the behaviour of WPS reduction. The main predictors of reduction in WPS are behavioural confidence, social environment change, and participatory dialogue. CONCLUSIONS: Findings of the research showed that the belief in an individual's ability, support from friends and the benefits of WPS reduction are the most important factors in reducing WPS among students. Therefore, it is suggested that comprehensive interventions be developed to improve the individual and social factors that are effective in WPS reduction.

The role of sociodemographic factors associated with waterpipe smoking among male adolescents in western Iran: A cross-sectional study.

INTRODUCTION: Waterpipe smoking (WPS) is an increasingly popular leisure activity among young people in Iran. The purpose of this study was to identify the role of sociodemographic factors associated with WPS among male adolescents in Iran. METHODS: The study used a cross-sectional design. It included 730 high school male students (Grades 10-12) recruited through multistage random sampling conducted in 2017 in Hamadan city, western Iran. The self-administered questionnaires included information on demographic variables and behavioral risk factors related to WPS. Descriptive statistics and multinomial logistic regression modeling were conducted using SPSS. RESULTS: The student mean age, and standard deviation (SD), and age at WPS initiation were 16.41 (0.84) and 13.31 (2.43) years, respectively. The percentages of never, former and current WPS were 37.3%, 36.4% and 26.3%, respectively. We found that ever cigarette smoking (OR=5.14, 95% CI: 2.56-10.32) and WPS family (OR=2.55, 95% CI: 1.40-4.64) were significantly associated with former WPS. Furthermore, being 18 years, studying in technical fields, reporting ever and current smoking of cigarettes and family usage of WP were significantly associated with current WPS. Friends with WPS (OR= 0.50, 95% CI: 0.34-0.72) however played a protective role on former WPS. CONCLUSIONS: The results indicate that the prevalence of former and current WPS was high in Hamadan city. Thus, designing and implementing interventions for increasing students', friends' and family's awareness regarding the harms of WPS and cigarette smoking are necessary to facilitate behavior change.
