Abstract Background: Little is known about age and gender specific attitudes to performance enhancing drugs and methods or other characteristics by which attitudes may vary. Methods: Using a population based cross-sectional sample of 1,703 Danish men and women aged 15-60 years, the present study examined age and gender variation in attitudes to performance enhancing drugs and methods. Response rate was 34 %. Information on attitudes was collected by questionnaire. Results: Overall, participants held negative attitudes to drugs and methods enhancing predominantly cognitive abilities enhancing performance drugs and to appearance modifying methods, but were positive to drugs for restoring physical functioning conditions. However, attitudes varied nonlinearly across age. Lenient attitudes peaked at age around 25 and subsequently decreased. Lenient attitudes to use of drugs against common disorders decreased in a linear fashion. No gender differences were observed and attitude did not vary with level of education, self-reported health or weekly hours of physical activity. Conclusion: The present study expands existing knowledge about attitudes toward PEDM with respect to age and gender specific differences. Future studies should take age variations into account, when examining attitudes to PEDM in the general population.

Abstract Background This is a cross-sectional study to explore the age and gender specific association between obesity and depression in Chinese rural adults. Methods A total of 29,900 eligible participants from the Henan Rural Cohort Study were included. Standard anthropometric measurements were undertaken to obtain data on body mass index (BMI) and waist circumference (WC). The Patient Health Questionnaire-2 (PHQ-2) was utilized to discover depressive symptoms. Logistic regression was performed to explore the association between obesity (independent variable) and depressive symptoms (dependent variable). Results There were 1777 subjects with depressive symptoms, accounting for 5.94%. After multivariable adjustment, compared with normal weight group, the odds ratios (ORs) [95% confidence interval (CI)] for depressive symptoms in underweight, overweight and general obese groups were 1.41 (1.08–1.84), 0.87 (0.78–0.97) and 0.86 (0.74–0.99), respectively. Similarly, the OR (95% CI) of abdominal obesity group was 0.84 (0.76–0.93). Besides, there was linear decreasing trend of WC with depressive symptoms, but not BMI. Moreover, the inverse association between obesity and depressive symptoms was stronger in men and the elderly than that in women and the young. Conclusion Underweight was associated with a higher prevalence of depressive symptoms, which indicated that health care should pay attention to underweight as well as obesity, especially for women and the young. Clinical trial registration The Henan Rural Cohort Study has been registered at Chinese Clinical Trial Register (Registration number: ChiCTR-OOC-15006699). Date of registration: 2015-07-06.

ObjectivesData on the problem of physical activity-related injury (PARI) in university students and the risk factors for PARI among different genders are rare. We conducted a multicentre population-based study to investigate the occurrence of PARI and to explore the gender-specific risk factors for PARI among Chinese university students.DesignCross-sectional study.ParticipantsA total of 5341 students in grades 1–3 at eight universities in four Chinese cities were selected to complete the online questionnaires during March and April 2017. The questionnaires assessed sociodemographic characteristics, physical activity PA) involvement, sleep duration, sedentary behaviour and PARI experiences in the past 12 months.Main outcome measuresPARI during the past 12 months.ResultsAmong the 5341 participants, 1293 suffered from at least one PARI in the past 12 months, with an overall incidence rate of 24.2% (males: 26.2%, females: 23.2%) and an injury risk of 0.38 injuries/student/year (males: 0.48, females: 0.32). Over half of the injured (57.3%) experienced a withdrawal time of PA and nearly two-fifths (39.6%) required medical attention. Irrespective of gender, Shantou and Xi’an students, sports team members and those who engaged in sports and leisure-time vigorous-intensity PA (VPA) at a higher frequency were more likely to suffer from PARI. Male students who participated in sports and leisure-time VPA for long durations had a greater likelihood of sustaining PARI, while having a chronic condition and being involved in sports and leisure-time moderate-intensity PA at a higher frequency and longer duration were potential contributors to PARI among females.ConclusionsThe occurrence of PARI and its risk factors differed by gender, which provides a direction towards developing targeted and effective gender-specific preventative programmes to protect Chinese university students from PARI.

ObjectivesTo establish reference intervals (RIs) for spinal mobility measures as recommended for patients with axial spondyloarthritis, and to determine the effect of age, height and gender on spinal mobility, in normal individuals.MethodsA cross-sectional study (MOBILITY) was conducted among normal individuals aged 20–69 years. Recruitment was stratified by gender, age (10-year categories) and height (10 cm categories). Eleven spinal mobility measures were assessed. Age specific RIs and percentiles were derived for each measure.Results393 volunteers were included. All spinal mobility measures decreased with increasing age. Therefore, age specific RIs were developed. The 95% RIs (2.5th and 97.5th percentiles), as well as the 5th, 10th, 25th, 50th, 75th and 90th percentiles for each spinal mobility measure and different ages are presented. Mobility percentile curves were also plotted for each of the measures. For instance, the 95% RI for lateral spinal flexion was 16.2–28.0 cm for a 25-year-old subject, 13.2–25.0 cm for a 45-year-old subject and 10.1–21.9 cm for a 65-year-old subject. After adjustment for age, there was no need for gender specific RIs, while RIs of some measures are height-adjusted.ConclusionsAge specific RIs and percentiles were derived for each of the spinal mobility measures for normal individuals. These may guide clinicians when assessing the mobility of patients with axial spondyloarthritis. The RIs may serve as cut-off levels for ‘normal’ versus ‘abnormal’, whereas the mobility percentile curves may be used to assess the level of mobility of patients with axial spondyloarthritis.

Abstract Objective: The primary purpose of this study was to establish Turkish smoothed centile charts and LMS tables for four-site skinfold thickness based on a population-based sample and secondary purpose was to elaborate a reference for the percentage of body fat. Design: A cross-sectional and descriptive study was conducted between January and May 2017. Triceps, biceps and subscapular, suprailiac skinfold thickness were measured using Holtain skinfold caliper. Age and gender specific percentile values were determined with the LMS method, and body fat percentage was calculated using the Westrate and Deurenberg equation. Setting: Afyonkarahisar province in Turkey. Participants: This study was conducted on 4565, 6-18 years old students. Results: The triceps, biceps, and subscapular skinfolds of the girls were higher than the boys. From the age of seven, the sum of four skinfold thicknesses of the girls was more than those of the boys. This difference became more evident after the age of 12. Although fat percentages of girls showed a fluctuating change, it decreased with the age in boys. Westrate and Deurenberg equation fat percentages of girls until adolescence were lower than boys, but increased after 12 years of age and exceeded that of boys. Conclusions: This study has provided sex and age specific reference values for skinfold thickness, and has shown that obesity in girls is higher than in boys in schoolchildren in Afyonkarahisar. This study has also shown that skinfold thickness measurements are a valuable tool for screening obesity in children.

Background : Fibromyalgia syndrome (FMS) is defined as widespread and persistent pain in the musculoskeletal system. There are limited reports regarding the prevalence of fibromyalgia syndrome in patients with advanced kidney failure undergoing regular hemodialysis. Therefore, this study aimed to evaluate the prevalence of fibromyalgia syndrome and its risk factors in a large proportion of patients under the hemodialysis condition. Materials and Methods: In this cross-sectional study, 293 patients who were admitted to the hemodialysis ward were evaluated for fibromyalgia syndrome in an educational hospital. The questionnaire was designed according to symptom severity score (SS score) and widespread pain index (WPI) criteria. The correlation between FMS and various variables, including demographic, clinical, and biochemistry biomarkers, was also precisely calculated by logistic regression. Data were analyzed using SPSS v.17 statistics software. Results: The results showed that, of 293 hemodialysis patients, 130 patients (44.4%) had fibromyalgia, the mean age of patients with and without fibromyalgia was 61.09 ± 15.36 and 53.49 ± 15.38 years old, respectively (P = 0.001). Moreover, there was a significant difference in terms of gender among patients with fibromyalgia syndrome (P = 0.001). To note, there was no significant relationship between the kidney failure etiopathogenesis, duration of dialysis, body mass index (BMI), Kt/v index, history of peritoneal dialysis, and laboratory parameters with fibromyalgia in hemodialysis patients (P > 0.05). However, our findings revealed that both age and gender could be considered as the predictor variables associated with fibromyalgia in patients undergoing hemodialysis. Conclusion: Taken together, in this study, we found that age and gender would be the critical factors in terms of the fibromyalgia syndrome in patients undergoing hemodialysis.

Abstract Background Bone turnover and metabolic indicators are related to age and gender. Age and gender should be matched in subjects in disease control research of bone turnover and metabolism, but strict matching of gender and age increases the difficulty and cost of the research. Therefore, the aim of this study was to solve it is necessary to strictly match age and gender in clinical research in bone metabolism. Methods A cross-sectional study was conducted from the data were extracted from the HIS of ZhuJiang Hospital. Data relating to seven bone turnover and metabolic indicators from 1036 patients between January 2018 and October 2019 were analyzed. Results P1NP, β-CTx and 25(OH)D were significant different in individuals younger than 20 years of age. ALP was significantly higher in those under 20 years of age and lower at age 20–39 compared with other age groups. The concentrations of Ca and P were different among the groups aged 0–19, 20–39, and 40–59 years of age groups but exhibited no difference above 60 years of age. PTH expression was not dependent on age. P1NP, β-CTx and PTH concentrations were not significantly different between the genders within the same age group. ALP was significantly different between genders within the age range 20–59 years. Ca and 25(OH)D were significantly different between the genders for those older than 60. Serum P was significantly different in the two genders for those aged 40–79. Patients received both alfacalcidol and calcium treatment differently from the others in P1NP, β-CTx, Serum Ca, P and ALP. Conclusion P1NP and β-CTx were highly correlated with age. If these two indictors require analysis in a case control study, the patients and controls should be strictly matched by age under 20 years. The demarcation point for ALP was 40 years of age. Ca and P were strongly recommended strict matching according to age in disease research. The difference in P1NP, β-CTx, 25(OH)D and ALP between genders depends on age differences. Medication history should be considered in bone turnover and metabolic clinical research.

ObjectivesTo investigate the temporal trends in the prevalence and causes of visual impairment (VI) in South India.DesignPopulation-based cross-sectional studies conducted during the years 2011–2012 and 2017 using identical study methods and in geographical locations are compared. The L V Prasad Eye Institute established services in Khammam and not in Warangal district after the 2011–2012 study.SettingKhammam and Warangal districts in Telangana, India.ParticipantsIn total, 5357 participants aged ≥40 years were examined from two districts in the 2011–2012 study and 4923 participants were examined in the 2017 study.Main outcome measuresAge-adjusted and gender-adjusted temporal trends in the prevalence and causes of VI.Blindness and moderate VI (MVI) were defined as presenting visual acuity worse than 6/60 and 6/18–6/60 in the better eye, respectively. VI included MVI and blindness.ResultsNearly 2500 participants were examined in each location in both the 2011–2012 and 2017 studies. In Khammam district, overall VI declined by 2.5% from 15.5% to 13.0% (p<0.001). While there was no significant change in MVI (p=0.566), blindness declined by 3.0% from 5.4% to 2.4% (p<0.001). In Warangal district, the overall VI remained unchanged (p=0.60). While MVI increased by 3% from 9.3% to 12.3% (p=0.001), blindness declined by 3.5% from 6.5% to 3.0% (p<0.001). While MVI due to cataract increased in both districts, there was a significant decline in MVI due to refractive errors in Khammam.ConclusionThere was a significant decline in VI in Khammam district but not in Warangal district. The differential trends in prevalence and causes of VI can be explained by the availability and uptake of eye care services in these two districts.
