Background: Do gender, age, body mass and height influence eye biometrical properties in young adults? Methods: A total of 155 eyes (92 female, 63 male) of healthy subjects between the ages of 18 and 39 years were included in the study. The subjects’ gender and age were recorded, and their body mass, height and biometrical properties of the eyes were measured. Results: The male subjects had significantly thicker and flatter corneas and lower minimal rim-to-disk ratios than the female subjects did. In both genders, age showed strong, negative correlations with anterior chamber depth and pupil diameter and a positive correlation with lens thickness. We also found significant, negative correlations between body height and mass with keratometry measurements, negative correlations between body height and optic disk rim area and rim volume, and positive correlations between body mass and axial length in both genders. Conclusions: Biometric eye parameters differ among people. In addition to age and gender, which are usually taken into consideration when interpreting ocular biometry findings, we strongly suggest that body height and mass should be also routinely considered when interpreting eye biometry data, as these factors have an impact on ocular biometry.

Summary Objectives: To improve insight into age and gender related distributions of serum lipids and their correlation with body mass index (BMI). Methods: Serum lipids embracing atherogenic index (AI) and BMI were analyzed from the results obtained in 19,823 men and 14,788 women undergoing a health examination between 1986 and 1996. Results: The changes in total cholesterol (TC), triglyceride (TG), AI and BMI differed regarding gender. Although high-density lipoprotein-cholesterol (HDL-C) showed a flat pattern for all ages in both genders, its level in women was higher than in men. The ratio of the number in the unsuitable range to those in the suitable range increased with age as to TC in both sexes, then more than half of the population have an unsuitable level in the sixth decade. As for the correlation between serum lipids and BMI: TC, TG and AI correlated positively, but HDL-C correlated negatively. There were significant gaps between both age and gender. Conclusions: We suggest that the normal range of values of serum lipids needs to be revised according to gender and age to evaluate the risk status for a cardio-cerebrovascular disease more precisely in the field of preventive medicine. Simpler guidelines are preferable in specialized care as well as in general practice, particularly since computer technology is not yet universally adapted. In the near future, when computed information technology will be as common as the electricity and the telephone are current on the whole earth, all guidelines will have to be computed on the spot and personally.

Background: A musician’s many years of professional experience may contribute to the development of pain and musculoskeletal disorders. There are a few studies in Poland on gender differences in musculoskeletal pain among adult professional musicians. Aim of the study: This study aimed to assess and compare pain in Polish women and men who are professional musicians, as well as to analyze the relationships between the intensity and frequency of pain and the time spent playing each week and the experience of playing the instrument in years. Material and methods: Sixty professional musicians were examined (26 men and 34 women). Pain intensity was assessed using the visual analog scale (VAS). Participants reported the frequency of musculoskeletal system ailments, the location of the pain, the number of hours of playing the instrument per week, and the playing experience in years. In addition, body weight and height were measured and body mass index (BMI) was calculated. Results: Most of the participants (94% of women and 69% of men) reported pain in the musculoskeletal system (p=0.010). Women experienced significantly greater pain in the musculoskeletal system assessed using the VAS (p=0.036), and also declared pain significantly more often compared to men (p=0.002). Significant positive correlations were found between frequency of symptoms per week with the number of hours of playing per week (r=0.28), year of playing the instrument (r=0.38), and pain assessment on the VAS (r=0.57). Moreover, negative correlations were found between frequency of symptoms per week with body height (r=–0.45) and body mass (r=–0.36). Conclusions: Musculoskeletal disorders are very common among professional musicians, especially among women. In general, the greater the number of hours playing per week and the longer the history of playing, the greater the pain intensity. Future research should aim to evaluate the prevalence and risk factors of musculoskeletal disorders associated with playing an instrument in different groups of musicians.

Abstract Purpose To extend currently available sex and age-specific normative values in children and adolescents for the peak work rate (WRpeak) attained at the steep ramp test (SRT) to healthy active young adults. Methods Healthy male and female participants aged between 19 and 24 years were recruited. After screening and anthropometric measurements, participants performed a SRT on a cycle ergometer (increments of 25 W/10 s), monitoring and recording SRT-WRpeak, heart rate (HR), and blood pressure (BP) at rest and directly after peak exercise. Results Fifty-seven participants (31 males and 26 females; median age of 21.3 years) volunteered and were tested. Anthropometrics, resting BP and lung function were all within normal ranges. Ninety-three percent of the participants attained a peak HR (HRpeak) > 80% of predicted (mean HRpeak 87 ± 5% of predicted). No differences were found in resting and peak exercise variables between females and males, except for absolute SRT-WRpeak (350 W [Q1: 306; Q3: 371] and 487 W [Q1: 450; Q3: 517], respectively) and SRT-WRpeak normalized for body mass (relative SRT-WRpeak; 5.4 ± 0.5 and 6.2 ± 0.6 W/kg, respectively). Low-to-moderate correlations (ρ [0.02–0.71]) were observed between SRT-WRpeak and anthropometric variables for females and males separately. Extended reference curves (8–24-year-old subjects) for SRT performance show different trends between male and female subjects when modelled against age, body height, and body mass. Conclusions The present study provides sex-, age-, body height-, and body mass-related normative values (presented as reference centiles) for absolute and relative SRT performance throughout childhood and early adulthood.

The purpose of this study was to determine whether gender- and age-related differences in ankle joint complex (AJC) range of motion (ROM) exist in children (range 9–13 years), adolescents (14–16 years), and young adults (17–20 years), and to compare these data with those published for older subjects (21–79 years) using the same protocol. 15 A total of 120 subjects (58 males and 62 females) ranging in age from 9 to 20 years were tested for AJC ROM using a specifically designed 6° of freedom fixture. 1 All measurements were made with respect to a laboratory coordinate system, and represented assessment of active AJC ROM. Angular displacements for plan-tarflexion, dorsiflexion, inversion, eversion, abduction, and adduction were digitally recorded and compared. AJC ROMs of females aged 9 to 20 years were generally greater than those for males about all three orthogonal axes. Within each gender, there was a consistent trend for AJC ROM to decrease from a maximum at 14 to 16 or 17 to 20 years to a minimum after age 60 years. The average decrement was greater for females than for males. This study provided evidence to support the contention that age-related and gender differences in AJC ROM do exist. The possibility of minimizing the decline in AJC ROM with age requires further investigation.

As Stress

Young adults face different stressors in their transition to college. Negative emotions such as stress can emerge from the demands they face. This study aimed at gaining an improved understanding of the role that gender and age play in the well-being of young adults. Coping strategies, resilience, self-regulation, and positivity were selected as indicators of well-being. Descriptive and inferential analysis have been conducted. Results show that well-being varies significantly with age and gender. Gender was predominantly involved in the acquisition of the well-being outcomes, highly predicting problem-focused coping strategies. No interaction effects were found between gender and age. An improved understanding of the developmental factors involved in well-being outcomes will enlighten future interventions aimed at improving young people’s resources to face adversity.

Abstract Background There are few studies reporting the association between stature and ocular biometry as well as cycloplegic refraction in young adults. Our study determined the relationship between stature and ocular biometry as well as cycloplegic refraction in Chinese young adults. Methods This was a school-based study including university students in Anyang, Henan Province, China. Cycloplegic refraction and corneal curvature (CR) were measured using an autorefractor. Ocular biometric parameters, including axial length (AL), anterior chamber depth (ACD), and lens thickness (LT), were measured using a Lenstar LS900. Height and weight were acquired from an annual standardized physical examination, and body mass index (BMI) was calculated from these measurements. Results A total of 5657 (71.0%) subjects were available for analysis. After adjusting for age, gender, parental myopia, time outdoors, near work and weight, a 1 cm taller person could be expected to have more negative refraction as -0.023D, a 0.032 mm increase in AL, a 0.003 mm increase in ACD, a 0.008 mm increase in CR, and a 0.001 increase in axial length-corneal radius (AL/CR) ratio. With regard to weight, a 1 kg heavier person was more likely to have less negative refraction as 0.011 D, deeper ACD by 0.001mm and flatter cornea by 0.002mm. A similar pattern of significant associations was also found in BMI. Conclusions Compared to those of less height, young adults of greater height tended to have longer eyes, deeper anterior chambers, flatter corneas, higher AL/CR ratio, and more negative refraction after controlling for potential confounders. In contrast, heavier and higher BMI persons were more hyperopic. The differences in stature may partially explain the variation in refraction and ocular biometric parameters.

Context Severe obesity affects the body favoring the development of serious diseases, including hypertension, diabetes mellitus, atherosclerosis and non alcoholic fatty liver disease. Bariatric procedures increased in Brazil in the last decade. Objectives The purpose of this study was to verify if gender and age in date of procedure resulted significant differences in metabolic syndrome parameters after surgery. Methods The study involved 205 medical records of adult patients undergoing Roux-en-Y gastric bypass, stratified by gender and age groups and followed one year by a multidisciplinary team. Results It was observed significant decrease in body mass index, fasting glucose and insulin at all ages and both genders. Lipid profile showed significant improvements except high density lipoprotein cholesterol. Ectopic fat in the liver has decreased after 6 months in patients classified with steatosis at baseline. Patients classified as hypertensive blood pressure levels decreased 6 months after surgical intervention. Conclusions Roux-en-Y gastric bypass proved to be an important tool in remission of metabolic syndrome parameters. The reduction of body mass accompanied to decrease in insulin resistance resulted in lower prevalence of comorbidities associated with obesity. The benefits were similar and extended both genders and all age groups between 18 and 65 years old.
