AbstractNearly 80% of new cases of myopia arise between 9 and 13 years old when puberty development also progresses rapidly. However, little is known about the association between myopia and puberty. We aim to evaluate the association between myopia and menarche, the most important puberty indicator for girls, and to test whether menarche could modify the effects of myopia-related behaviors. The participants came from two consecutive national surveys conducted in 30 provinces in mainland China in 2010 and 2014. We included 102,883 girls (61% had experienced menarche) aged 10–15 years. Risk behaviors for myopia which included sleep duration, homework time, and outdoor activity were measured by self-administrated questionnaire. Myopia was defined according to a validated method, and its relationships with menarche status and behaviors were evaluated by robust Poisson regression models based on generalized estimated equation adjusting for cluster effect of school. We found that postmenarche girls were at 13% (95% confidence interval: 11%–16%) higher risk of myopia than premenarche girls, after adjusting for exact age, urban–rural location, survey year, and four behavioral covariates. Short sleep duration (<7 h/d), long homework time (>1 h/d) and low frequency of weekend outdoor activity tended to be stronger (with higher prevalence ratios associated with myopia) risk factors for myopia in postmenarche girls than in premenarche girls, and their interaction with menarche status was all statistically significant (P < 0.05). Overall, our study suggests that menarche onset may be associated with increased risk of myopia among school-aged girls and could also enhance girls’ sensitivity to myopia-related risk behaviors.

Background: Young people who are not in education, employment or training (NEET) have been identified as a vulnerable group at risk of poor social functioning, lower educational achievement, limited job opportunities and financial hardship. Being NEET has also been associated with increased risk of mental and physical health problems, but only a few studies have identified the prevalence of certain health-risk behaviors among NEET youth. The present study contributes to fill the existing knowledge gaps by investigating a broad range of risk behaviors in this vulnerable group compared to their high school peers.Methods: This cross-sectional study included 96 NEET youth and 384 age and gender-matched high school students. A self-report questionnaire was used to assess differences in several risk behaviors, including substance use, low consumption of healthy food and high consumption of unhealthy food and beverages, low leisure time physical activity and low sleep duration. Logistic regression models were adjusted for gender, age and parental education.Results: NEET youth had higher odds of using cannabis (OR 2.2; 95% CI 1.1-4.3), smokeless tobacco (1.7;1.0-2.8), smoking cigarettes (2.6;1.5-4.4), having an irregular consumption of breakfast (2.6;1.5-4.5), lunch (3.1;1.8-5.4) and dinner (1.9;1.1-3.2), having low consumption of vegetables (3.0;1.3-6.7), fruit and berries (5.3;1.6-18.1) and fish (3.0;1.8-5.1) and short sleep duration on weekends (2.6;1.4-4.9) than students. On the other hand, being NEET was associated with decreased odds of short sleep duration on weekdays compared to their high school peers (0.3;0.2-0.5). No differences in alcohol intoxication, consumption frequency of evening meals, consumption of unhealthy food items and beverages and leisure time physical activity were shown between these groups.Conclusions: NEET youth have higher odds of using tobacco, short sleep duration on weekends and lower consumption of healthy food items including vegetables, fruit and fish compared to high school students. These results contribute to identify risk behaviors that are more prevalent among NEET youth compared to students and needs to be addressed through targeted intervention studies.

ObjectivesShort sleep duration is independently associated with an increased risk of developing cardiovascular disease; however, the association has not yet been examined in obese populations. We assessed the associations between sleep duration, metabolic phenotype and apolipoprotein variables in a nationally representative Chinese population with overweight/obesity.Study designCross-sectional study.SettingsThe study conducted in nine provinces of China that vary substantially in geography and economic development.PatientsData were obtained from 4149 adults with overweight/obesity aged 18 to 94 years from the 2009 China Health and Nutrition Survey. Sleep duration was categorised as ≤6, 7–8 or ≥9 hour. Phenotypes were determined based on body mass index and metabolic health status and categorised as metabolically healthy overweight/obesity (MHOO) and metabolically unhealthy overweight/obesity (MUOO).Main outcome measureThe outcome variables were elevated apolipoproteins.ResultsCompared with MHOO phenotype, MUOO phenotypes were more likely to report shorter sleep duration (12.2%vs9%). In the MUOO group, the multivariate-adjusted OR (95% CI) for elevated apolipoprotein B (apoB) was 1.66 (1.23 to 2.23) for those with ≤6 hours of sleep and 1.12 (0.86 to 1.45) for those with ≥9 hours of sleep, using 7–8 hours of sleep as a reference. Similar results were obtained in the subgroup of subjects who were ≥45 or<45 years old, but shorter sleep duration was more strongly associated with elevated apoB in those <45 years (p interaction=0.023). However, no association was observed in the MHOO phenotype.ConclusionsThe high prevalence of short sleep duration and its strong association with elevated apoB in adults who are metabolically unhealthy overweight/obese suggest an increased risk of cardiovascular disease in this population. The differences in sleep sufficiency among obese phenotypes may account for the disparities in their cardiovascular outcomes.

ObjectivesPrevious studies have reported that sleep duration might increase the risk of hypertension. However, the results have been conflicting. We investigated whether sleep duration is independently associated with hypertension. We aimed to assess the relationship between sleep duration and hypertension in a population-based cross-sectional study.MethodsIn this study we used multistage stratified cluster sampling. A total of 19 407 adults aged 18–79 years were enrolled in the study. The participants were divided into three groups (<7 hours/day, 7–8 hours/day and >8 hours/day) according to self-reported sleep duration. Hypertension was defined as systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or the use of anti-hypertensive medications. Univariate and multivariate logistic regressions were performed to determine the association between hypertension and sleep duration adjusted for sociodemographic, body mass index, and lifestyle covariates.ResultsThe overall prevalence of hypertension was 32.6%. Among participants aged 18–44 years, individuals sleeping less than 7 hours per day had a higher risk of hypertension (OR=1.24, 95% CI: 1.05 to 1.46), compared with those who slept 7–8 hours per day. There were no significant associations between sleep duration and hypertension in the total sample, among middle-aged adults (45–59 years) or older adults (60–79 years).ConclusionsOur study demonstrates that short sleep duration was significantly associated with hypertension among people aged 18–44 years in northeast China.

AbstractA negative association between sleep duration and BMI has been observed in children. However, knowledge about the association between sleep duration and diet is limited. The objective was to examine the association between sleep duration and intake of foods and nutrients in children. In the present cross-sectional study, dietary intake and sleep duration were recorded by the parents for seven consecutive days in a food and sleep record in a representative sample of 802 4- to 14-year-old children. No sex differences were found regarding age and sleep duration. Sleep duration was negatively correlated to age (ρ = –0·68; P < 0·001) and BMI (ρ = –0·41; P < 0·001). In multiple linear regression analyses, sleep duration was not associated with energy intake (b = –0·015; P = 0·20), but there was a trend towards a positive association with intake of dietary fibre (b = 0·006; P = 0·05) and vegetables (b = 0·011; P = 0·05), and a negative association with intake of poultry (b = –0·002; P = 0·02), and a trend towards a negative association with intake of liquid ‘discretionary calories’ (b = –0·01; P = 0·05). Furthermore, in a comparison of dietary intake between age-dependent tertiles of sleep duration, only intake of liquid ‘discretionary calories’ was significantly lower in long sleepers than in short and medium sleepers (P = 0·03). In conclusion, sleep duration was not associated with energy intake and the proposal that children with short sleep duration have less healthy eating habits than children with longer sleep duration was only weakly supported by the present findings.

The Relationship

Abstract Background A variety of health problems, such as metabolic syndrome (MetS), have been linked to sleep disorders. While numerous epidemiological studies have shown a U-shaped relationship between sleep duration and poor health outcomes, the results were limited and inconsistent. This study was designed to evaluate the relationship between sleep duration and MetS. Methods This population-based study was conducted on the participants aged 35–70 of Bandare-Kong Non-Communicable Diseases (BKNCD) Cohort Study, a part of Prospective Epidemiological Research Studies in IrAN (PERSIAN). MetS was diagnosed according to the National Cholesterol Education Program (NCEP) criteria and the Iranian-specific cut-off for waist circumference (≥ 95 cm). Sleep information was extracted through a standard questionnaire based on self-reported information. Data were analyzed by R software using generalized additive models (GAMs). A statistically significant level was considered as P < 0.05. Results A total of 3695 participants were included in the analyses. The mean age was 48.05 years (SD 9.36), and 2067 (55.9%) were female. The estimated Prevalence of MetS was 35.9%, and women appeared to be more likely to have MetS than men (P < 0.001). There was a non-linear and linear association between sleep duration and the risk of MetS in women and men, respectively. The lowest risk was observed among those with 7–7.5 h of sleep duration per night. Conclusion Long sleep duration was associated with increased risk of MetS and higher MetS severity score in both genders, while the short sleep duration increased the risk of Mets as well as MetS severity score just in women. The longitudinal studies would be suggested to assess the relationship between sleep quality and quantity components and MetS.

IntroductionCardiovascular disease is the leading cause of on-duty fatalities among U.S. firefighters. Research has demonstrated that many modifiable risk factors are contributors to the high prevalence of cardiometabolic risk factors. The current study aimed to assess whether sleep is associated with cardiometabolic risk factors among Indianapolis firefighters. The findings could support improving sleep hygiene in this population.Material and MethodsThis cross-sectional study was conducted from the baseline data of eligible firefighters enrolled in “Feeding America’s Bravest”, a Mediterranean diet lifestyle intervention within the Indiana Fire Departments. Participants’ sleep quality was categorized as “good” (≤ 8 points) or “bad” (&gt;8 points) by a sleep quality questionnaire based on some questions from Pittsburgh Sleep Quality Index. In addition, firefighters’ sleep duration was stratified based on the number of hours slept per night (≤6 as “short sleep” or &gt;6 hours as normal). Linear and logistic regression models were used to examine the association of sleep with cardiometabolic risk factors.ResultsA total of 258 firefighters were included. Bad sleepers had higher weight, greater waist circumference, higher body mass index (BMI), and increased body fat (all p&lt;0.01) compared to good sleepers. Similarly, participants with short sleep duration were heavier (p&lt;0.02), had greater BMI (p&lt;0.02) and increased body fat (p&lt;0.04) compared with participants with normal sleep duration. Both bad and short sleepers had a higher prevalence of hypertension and obesity (p &lt;0.05).ConclusionsOur study supports that both sleep quality and quantity are associated with cardiometabolic risk among firefighters.

Abstract: Obesity is defined as an abnormal accumulation of body fat in proportion to body size. Obesity is a public health crisis that is very substantial. The prevalence of obesity is increasing rapidly in many industrialized countries around the world and become a pandemic that needs immediate attention. Cause of obesity is more complex than the simple paradigm of energy imbalance, but various mechanisms contribute to obesity, including short sleep duration. The purpose of this study was to describe sleep duration and overweight adolescents and to determine the relationship of sleep duration and overweight. This research is an analytic survey with cross sectional study. Study was conducted in junior and senior high school Pax Christi and Rex Mundi Manado, obtained 32 samples of survey respondents with a body mass index above 23.0. Characteristics of the respondents, namely: Age between 14-16 years ever with 15 people (46.9%); Body mass index between 23 to 29.9 were 19 respondents (59.3%); Age at the start of fat, between the ages of 11-15 years as many as 20 people (62.5%); Data diet, greasy 15 respondents (46.9%); Data bedtime, sleep 5-7 hours a night, 21 respondents (65.6%), length of time between the 30 minute nap - 1 hour and between 1 – 2 hours have 13 respondents (40.6%) each. Based on the results of the study, short sleep pattern at night is associated with obesity among (teenage students) of the respondents. Increase and decrease grehlin / leptin, plays a role in relation to the increase in sleep patterns diets ultimately cause obesity. Keywords: Obesity, short sleep patterns, grehlin, leptin, increased appetite.Abstrak: Obesitas didefinisikan sebagai akumulasi abnormal dari lemak tubuh dibandingkan dengan ukuran tubuh normal. Obesitas merupakan krisis kesehatan masyarakat yang sangat substansial. Prevalensi obesitas meningkat dengan cepat di sejumlah negara industri di seluruh dunia dan menjadi pandemik yang memerlukan perhatian segera. Penyebab obesitas lebih kompleks daripada paradigma sederhana ketidakseimbangan energi, namun berbagai mekanisme turut berperan didalamnya, termasuk durasi tidur yang singkat. Tujuan penelitian ini adalah untuk mengetahui gambaran durasi tidur pada remaja dengan kelebihan berat badan dan untuk mengetahui hubungan durasi tidur pada remaja dengan kelebihan berat badan. Penelitian ini bersifat survey analitik dengan study cross sectional. Penelitian dilakukan di SMP Pax Christi dan SMA Rex Mundi Manado, diperoleh 32 sampel responden penelitian dengan indeks massa tubuh diatas 23,0. Karakteristik responden yaitu: Umur terbanyak antara 14-16 tahun yaitu 15 orang (46,9 %); Indeks massa tubuh antara 23-29,9 sebanyak 19 responden (59,3 %); Umur saat mulai gemuk, antara umur 11-15 tahun yaitu sebanyak 20 orang (62,5 %); Data pola makan, makanan berminyak 15 responden (46,9 %); Data waktu tidur, tidur malam 5-7 jam, 21 responden (65,6 %); Lama waktu tidur siang antara 30 menit-1 jam dan antara 1-2 jam yaitu masing-masing 13 responden (40,6 %). Berdasarkan hasil penelitian kesimpulannya, pola tidur yang singkat pada malam hari berhubungan dengan peningkatan berat badan dari responden.Peningkatan grehlin dan penurunan leptin, memegang peranan dalam hubungan pola tidur dengan peningkatan pola makan yang pada akhirnya menyebabkan kegemukan.Kata kunci: Obesitas, pola tidur singkat, grehlin, leptin, peningkatan nafsu makan.

Objective: To determine the prevalence of sleep quality in the elderly within our outpatient department.Material and Method: A cross-sectional study was conducted by; calculating the sample size for a survey with ‘proportion to size’ at the outpatient department of Songklanagarind Hospital from; October to November, 2015. A total of 408 participants aged between 65 and 99 were interviewed. Demographic and sleep-related data were collected. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) – Thai version. The results were analyzed in terms of descriptive statistics and conducted using R-Epicalc and R-Survey software.Results: Our subjects were predominantly married females. The proportion of those in the 65-74 age range was 63.0%.Most of the participants (70.8%) were poor sleepers, with mean and median PSQI scores of 7.7 and 7.0, respectively.Regarding poor sleepers, their problems were; short sleep duration (99.7%), poor sleep efficiency (61.6%) and daytime dysfunction (51.6%).Conclusion: Similarly to previous studies, our findings showed a high prevalence of poor sleep quality in the elderlypopulation. A sleep duration of less than 6 hours was the major problem in the poor sleeper group. Gaining a betterinsight into sleep quality correlating with comorbidities is recommended.
