The Impact

This cross-sectional study aimed to assess the impact of age and gender on 4 measures of grip and pinch force of well elderly community dwellers and to provide normative values. The hypotheses were that age and gender affect pinch and grip force and that these 2 factors might interact. Hand strength of 224 seniors 65–92 years old was tested. Grip and pinch force decreased in successively older age groups past 65 years. Men’s grip force exceeded that of women in all age groups. Men’s hand-force decline was steeper than that of women over successive age groups, suggesting that gender differences in force decreased with age. Trends were the same for all 4 types of grip- and pinch-force measurement but were most clearly visible in grip and key-pinch force. Norms were provided for seniors age 65–85+ years in 5-yr increments.

OBJECTIVES:  To analyze the impact of age and gender on iron stores in a population of the Nowshera region. METHODOLOGY: This cross sectional study was conducted in the Department of Pathology Qazi Hussain Ahmed Medical Complex Nowshera from 1st January 2019 to 31st March 2020. All patients were selected by convenience sampling in the Pathology department irrespective of age and gender.   Both descriptive and inferential statistics were applied to analyze data by the latest SPSS version 25.  RESULTS: Out of the total study population males were 70 (27.1%) and females 188 (77.9%) with median age 30 years.  The median ferritin level was 12.8 ng/ml. Out of total, 142 (55%) of cases were with serum ferritin less than 15ng/ml. A significant (p=0.03) gender based median ferritin level difference was observed with 1.5 times more probability of low iron stores in females as compared to males (OR=1.5). No statistically significant difference in body iron stores exists in different age groups. CONCLUSION:  A significant difference was noted in the iron stores in gender groups and the probability of depleted/low iron stores was higher in female gender as compared to male gender in all age groups in our population.

Sentiment analysis is a rapidly growing field of research due to the explosive growth in digital information. In the modern world of artificial intelligence, sentiment analysis is one of the essential tools to extract emotion information from massive data. Sentiment analysis is applied to a variety of user data from customer reviews to social network posts. To the best of our knowledge, there is less work on sentiment analysis based on the categorization of users by demographics. Demographics play an important role in deciding the marketing strategies for different products. In this study, we explore the impact of age and gender in sentiment analysis, as this can help e-commerce retailers to market their products based on specific demographics. The dataset is created by collecting reviews on books from Facebook users by asking them to answer a questionnaire containing questions about their preferences in books, along with their age groups and gender information. Next, the paper analyzes the segmented data for sentiments based on each age group and gender. Finally, sentiment analysis is done using different Machine Learning (ML) approaches including maximum entropy, support vector machine, convolutional neural network, and long short term memory to study the impact of age and gender on user reviews. Experiments have been conducted to identify new insights into the effect of age and gender for sentiment analysis.

Background/Aim. Dental appearance plays an important role in practically all personal social interactions. The main factors that define the dental appearance are tooth colour, shape and position, quality of restoration, and the general position of the teeth in arch, especially in the anterior region. The aim of this study was to evaluate the impact of dental status (tooth shape, fracture, dental and prosthetic restorations and presence of plaque) on patient''s satisfaction with the dental appearance, controlling for the age and gender. Methods. A total of 700 Caucasian subjects (439 women) aged 18?86 (median 45 years) participated in the cross-sectional study. Study included clinical examination and self-administrated questionnaire based on selfperceived aesthetics and satisfaction with the appearance of their maxillary anterior teeth. Results. A regression analysis demonstrated that presence of dental plaque, tooth fracture, composite fillings and crowns had significant independent contribution and were negative predictors of satisfaction with teeth appearance. Participants with presence of plaque on upper teeth (p < 0.001), fractures (p = 0.005), composite fillings (p < 0.001) and crowns (p = 0.032) were less satisfied than those without it. Model explains 12% or variance of general satisfaction with the appearance of maxillary frontal teeth (p < 0.001) and the major contributors are composite fillings (5.3%) and plaque (3.2%). Tooth shape, age and gender were not significant predictors of satisfaction. Conclusion. Satisfaction with the teeth appearance is under the influence of many factors with significant negative influence of presence of dental plaque, fractures, composite restorations, and crowns.

To establish the age- and sex-related normative values of sagittal alignment in asymptomatic Chinese adults, and to investigate the changes and possible associated compensation mechanisms across age groups. 584 asymptomatic Chinese adults aged 20–89 years were recruited. Subjects were grouped according to age and gender. Whole-body standing radiographs were acquired for evaluating sagittal alignment from spine to lower limb. Sagittal parameters between gender in different age groups were compared via independent t test. Pearson correlation analysis was used to demonstrate relationships between parameters. Thoracic kyphosis (TK) increased steadily while lumbar lordosis decreased gradually in both genders. Pelvic tilt (PT) in male is greater than in female across all age groups with age related gradual increase. There were significant differences between male and female from 20s to 60s in terms of knee flexion angle (KA) and ankle dorsiflexion angle (AA), but the differences were not significant after 60s. T1 pelvic angle (TPA) was significantly correlated with spinal, pelvic and lower-limb alignment. The older group (≥50 years) had a stronger correlation of TPA with PT and KA, whereas the younger (<50 years) had stronger correlation with TK. This study comprehensively presented the normative sagittal alignment based on a large asymptomatic population, which could serve as an age- and gender-specific reference value for spine surgeons when planning for correction surgery. Age can influence the recruitment of compensation mechanism that involve more pelvic and lower limb mechanisms for elderly people.

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.

PurposeThis paper tests and validates a conceptual model linking the attachment points, team identification, attitude towards the team sponsors and the behavioural intentions in the context of Indian Premier League (IPL), while testing for the moderating effects of age and gender.Design/methodology/approachData were collected from 1,053 participants through both online and offline survey and then analyzed using exploratory factor analysis (EFA) and structural equation modelling (SEM).FindingsAttachment points influence the formation of team identification, which, in turn, affect the attitude towards the team sponsors. Attitude towards the team sponsors influence the behavioural intentions. Player attachment influences team identification the most. Age and gender have a moderating effect on the constructs of the study. Team identification in females is stronger because of attachment to sports, whereas males have stronger team identification based on player attachment. Males have a stronger intention to spread positive word of mouth (WOM) about sponsor products as compared to the female respondents. The younger age group of less than 21 years has more intention to spread positive WOM compared to the other age groups considered in the study.Practical implicationsThis study contributes towards sports sponsorship research and the paradigms of social identity and attachment theories. Moreover, it will also help the marketers (sponsors) in IPL to strategically market their brands.Originality/valueThis is the first study to investigate the impact of attachment points on sponsorship outcomes in the context of IPL. Further, it is also the first to investigate the purchase intentions and WOM for the team sponsors in IPL. The multi-group analysis results will provide insights into marketers to better understand IPL viewers' segments and their behaviour.

Seasonality of 25(OH)D deficiency rate is a factor of major clinical and social impact and should be considered when planning for appropriate testing and tailored correction. We present retrospective cross-sectional analysis of over a million 25(OH)D tests performed in two leading Latvian laboratories – Central Laboratory and E.Gulbja Laboratory. Both series of tests demonstrated prominent seasonal variability of 25(OH)D deficiency rate (<20 ng/ml) and critical deficiency rate (<12 ng/ml): the lowest percentage of deficient tests was in August, while a significant peak was found in March-April. This trend was present at all ages and in both genders, variations were pronounced even for a high-latitude country and more prominent for critical deficiency, in younger age groups and in males. Analysis of testing regimens of both laboratories revealed that schedule was not optimal, period of higher testing intensity being far removed from the 25(OH)D deficiency peak.

Context: Dearth of normative data for bilateral shoulder rotation flexibility (BSRF) for Nigerians is currently a limitation in screening of athletes and patient management. Aims: This study was designed to generate normative values for BSRF among healthy Nigerians of different age groups using the shoulder rotation test (SRT). Settings and Design: A four-stage sampling technique was used in recruiting 4000 (male [Formula: see text] 2048; female [Formula: see text] 1952) participants into this cross-sectional descriptive survey. Methods and Material: Participants aged between 5 and 64 years were grouped into 12 age strata. Participants' BSRF was measured using the Acuflex III flexibility tester. Data were analyzed using descriptive statistics of mean, standard deviation and percentiles. Results: Participants' mean age was 24.22 [Formula: see text] 14.65 years. Participants’ BSRF increased with age thus indicating reduced flexibility with age. In the twelve age groups of 5–9, 10–14, 15–19, 20–24, 25–29, 30–34, 35–39, 40–44, 45–49, 50–54, 55–59 and 60–64, the BSRF for the male participants were 26.29 [Formula: see text] 12.64cm, 37.95 [Formula: see text] 16.15cm, 54.33 [Formula: see text] 21.08cm, 58.21 [Formula: see text] 23.01cm, 65.50 [Formula: see text] 22.67cm, 74.75 [Formula: see text] 17.06cm, 74.42 [Formula: see text] 17.06cm, 77.97 [Formula: see text] 16.38cm, 81.26 [Formula: see text] 14.88cm, 82.77 [Formula: see text] 14.42cm, 86.00 [Formula: see text] 14.82cm and 93.25 [Formula: see text] 12.73cm respectively. Those for female participants were 25.34 [Formula: see text] 12.28cm, 41.12 [Formula: see text] 15.48cm, 50.46 [Formula: see text] 18.60cm, 49.19 [Formula: see text] 19.75cm, 58.26 [Formula: see text] 17.16cm, 62.40 [Formula: see text] 16.72cm, 67.32 [Formula: see text] 18.50cm, 69.37 [Formula: see text] 17.14cm, 71.80 [Formula: see text] 15.18cm, 75.21 [Formula: see text] 15.57cm, 73.55 [Formula: see text] 14.09cm and 81.21 [Formula: see text] 10.89cm respectively. Males generally had higher scores (lesser flexibility) than females across the twelve age groups except for the 10–14 year age. The percentiles of the BSRF scores for the participants showed a steady increase in BSRF scores from age 5–9years to 60–64years. Conclusion: This study generated population-based normative values according to age and gender for BSRF using the SRT for healthy Nigerians.
