Introduction: Creation of anthropometric database in any age group is one of the most important issues in designing and manufacturing of used equipment. The aim of this study was to determine the anthropometric characteristics of nurses of kindergartens and preschools in Isfahan in the age range of 2 to 6 years and to create an information reference.Materials and Methods: In this applied study, 700 healthy male and female boys were selected randomly from cluster sampling from nursery schoolchildren and preschools in Isfahan city. 36 anthropometric measurements of them were cross-sectional in the academic year 1396 to 1397. And indicators and statistical percentiles (5.50 and 95) were extracted.Results: Statistical indexes and percentiles were presented as an anthropometric database in 5 age groups and in two sex groups. Age and sex were influenced by most anthropometric variables and significant difference (P <0.05). .Conclusion: The age and sex are two factors affecting anthropometric variables. Therefore, it is necessary to use the anterpometric database of the same age group and gender in the design of the equipment.

Urinary schistosomiasis is a severe threat to global health with uncountable morbidities in Africa including Nigeria where control interventions focused on children in public and private schools neglecting Almajiri children. This undermined control interventions as those infected contaminate the environments with infective stages of the parasite. The objective of the study was to identify the prevalence of urinary schistosomiasis amongst Almajiri children in Silame, Sokoto State, North-western Nigeria. This was a cross-sectional descriptive study, socio-demographic data was collected in April 2020 on 206 consented Almajiri children in Silame and their urine samples were examined using the sedimentation method. The study showed a prevalence of 35.4% among the Almajiri children in Silame, Sokoto State, North-western Nigeria. The highest prevalence was found among children within the age range 16-20 years (63.6%) while the lowest prevalence was among those in the age range 6-10 years (24.4%). There was a statistically significant difference in the occurrence of urinary schistosomiasis between the age groups (χ 2 = 11.637a , df =3, p=0.002). Urinary schistosomiasis was prevalent among Almajiri children in the study area and parasite infection was associated with the participant's socio-demographic factors such as age, level of education, and water contact activities. Hence, the National Schistosomiasis Control Programs should incorporate the Almajiri children in the control interventions Keywords: Schistosoma hematobium infection; Makarantarallo;Almajiri;Silame

This is a cross sectional study conducted among Currently Married Women of Reproductive Age (CMWRA) with a sample size of 476 selected purposively using a semi-structured questionnaire in 2018 at Moulvibazar Sadar to explore the factors affecting fertility. The result shows that 55.26% respondents were within 35 years age whereas only 4.28% from age group 46-49 years age group, 33% of the respondents got married at <16 years of age and 18.70% were illiterate, 47.90% had primary education. It is evident that 76% of the respondents were from rural area; 88% were Muslims, 29.41% from lower middle class followed by upper middle class (25.42%) and poorest comprised only 7.56%. The result explored that 73.91% of the respondents were from age group 41-45 got married before 16 years of age followed by 36-40 years (68.24%), 46-49 years (66%), 20-25 and 26-30 years age groups 52.38% and 52.75% respectively; 73.33% of respondents from rural area got married at <16 years of age, 68.42% of the Muslim at <16 years. The study explored that 96.39% from poorer section and 83.33% from poorest section got married at <16 years of age. Current study revealed that 82.91% of the respondents having secondary education got married before 16 years of age followed by illiterate (82.02%). It is explored that the age at marriage is statistically associated with residence, education, wealth index and religion (p= 0.001, 0.03, 0.001, 0.001 respectively). We conclude that the sociodemographic condition contributes mostly to fertility differentials in Bangladesh.

ABSTRACT BACKGROUND: The bacterium Helicobacter pylori is strongly associated with the development of gastric adenocarcinoma. Currently, the prevalence in developed countries is 40%, but this value increases considerably in developing countries, which can reach rates bigger than 90%. OBJECTIVE: The objective of this study was to determine the mean and annual prevalence of Helicobacter pylori infection in patients from Itajaí during the period from July 1992 to April 2016, as well as the gender and age groups most affected. METHODS: After consent of the clinical director of the Gastroclinica Itajaí and confidentiality commitment about the research, the database of the Endoscopy Service of the clinic was evaluated. All the patients who underwent their first upper digestive endoscopy with urease test and/or histological analysis were included. The data were submitted to statistical analysis of prevalence by gender, age group and years of study, with subsequent correction through the confidence interval. RESULTS: The mean prevalence of Helicobacter pylori infection thru all years of study was 50.07%. With the calculation of the annual prevalences, it was evident the gradual reduction of infection in the population of Itajaí, that was 81.3% in 1992, declining to 33% in the year of 2016. When classifying the prevalence of infection by gender, it was higher in males (53.59%), and gender distribution by age group showed no statistically significant difference among genders between the ages of 40 and 80 years. In relation to the age group, the highest prevalence was in the group between 40 and 49 years. CONCLUSION: Although this study is retrospective and based on endoscopic database analysis, without access to clinical data of patients such as prior use of proton pump inhibitor and antibiotics to endoscopy, its results are important because they may reflect the current panorama of Helicobacter pylori infection in the city under study, where it has been presenting a gradual reduction of prevalence over the years, with current rates similar to that of developed countries (33%). Future studies are needed to confirm our data.

This cross-sectional study aimed to determine the degree of visibility of maxillary and mandibular anterior teeth at rest in different age groups and to evaluate the smile line, smile arc, and number of maxillary teeth displayed during smiling among the Saudi population visiting King Abdulaziz University Dental Hospital, Jeddah, Saudi Arabia. A total of 157 participants (77 males and 80 females) were included in this study with an age range of 19 to 69 years. All participants had maxillary and mandibular anterior teeth without restorations. Crown length and visible portions of anterior teeth at rest were measured using a Fowler Electronic Digital Caliper. Three measurements of each variable were recorded by two independent dental interns and calibrating their measurements was performed. Smile line, smile arc, and number of teeth displayed during smiling were examined. The collected data were statistically analyzed using SPSS software. It was found that the average clinical crown lengths in the maxillary lateral incisor, mandibular central incisor, and canine were significantly higher in males than females. At rest position, females displayed more maxillary central and lateral incisors. The displayed length of maxillary teeth at rest is inversely proportional to increasing age; the reverse occurs in mandibular teeth. The common visibility of maxillary teeth during smiling was from the second bicuspid to its counterpart. Average smile line and consonant smile arc were the most common characteristics. It was concluded that both age and gender affect the characteristics of tooth display at rest and in smiling. These effects should be considered during treatment planning and restoration of anterior teeth to obtain a more predictable esthetic outcome.

Introduction and Aim: Osteoporosis is a skeletal disorder characterized by diminished bone strength that increases the risk of fracture in instances of trivial trauma. The objective was to conduct ultrasound bone densitometry in different age groups (18-60 years and older) in southern Kyrgyzstan, to identify and study the prevalence of osteopenia and osteoporosis.   Materials and Methods: In this cross-sectional observational study a total of 1200 participants were included, where 580 men and 620 women were aged between 18-60 years and older. Based on the age, the participants were divided into three groups. Bone mineral density in participants was measured using a SONOST-3000 densitometer model. The study was conducted among the population of the Osh and Jalal-Abad regions.   Results: Among the population of Osh state in the first group, normal values were found in 65.0%, osteopenia in 26.0%, and osteoporosis in 9.0% of participants. In the second group, values were significantly higher than in the first group. In the third age group, values exceeded significantly compared to the first and second groups. Similar data were obtained from the population of Jalal-Abad state, but a significant difference was found in the elderly people group with a higher percentage of osteopenia and osteoporosis.   Conclusion: The results showed the prevalence of osteopenia and osteoporosis in participants of different age categories of Osh and Jalal-Abad states, and especially in the elderly. Depending on the gender distribution, the prevalence of osteopenia and osteoporosis in our study is significantly higher in women than in men.

Background: Pakistan has the second highest prevalence of hepatitis C in the world after Egypt. Viral hepatitis is a leading cause of morbidity and mortality in Pakistan and, worryingly, reinfection rates are also on the rise. This cross-sectional study was aimed at finding the most common genotypes of hepatitis C in terms of age and sex in a Pakistani cohort. Materials and methods: The authors collected blood samples from 1,260 patients with diagnosed hepatitis C visiting a primary teaching hospital affiliated with Peshawar Medical College, Pakistan, from different districts of Khyber Pakhtunkhwa, Pakistan, between January 2017 and April 2019. Hepatitis C virus RNA was quantified by real-time polymerase chain reaction and genotyping was then performed. Results: The authors found that genotype 3a was the most prevalent type followed by 1a, mixed, and 3b, respectively. Genotypes 2a and 1b were the least prevalent in Khyber Pakhtunkhwa. The most common genotype was 3a, observed in 75.87% of cases. The most common mixed genotype was 3a+1a, observed in 39 cases (3.10%); it had a prevalence of 3.49% in females compared with 2.70% in males. Overall, the most common age group affected by hepatitis C virus was 41–50 years (31.35%), followed by the 51–60 years group (24.45%). Infection rate was comparatively low in other age groups. A significant difference was observed in the prevalence of genotype 3a and 2a among different districts. Conclusion: The authors concluded that genotype 3a was the most prevalent genotype and it was observed more frequently in the female population, with a median age of 45 years.

Cardiorespiratory fitness is an important health status indicator. The purpose of this study was to verify the cardiorespiratory fitness according to age group and gender in children and adolescents from Sergipe, Brazil. It is a cross-sectional study with sample consisting of 195 adolescents of both genders with mean age of 11.75 ± 3.0 years. For the characterization of participants, a questionnaire with age and gender identification designed by researchers was used. Subsequently, participants were submitted to anthropometric evaluation in order to estimate the maturational stage by means of the peak height velocity (PHV). The 20-meter back-and-forth test was used to estimate cardiorespiratory fitness. Two-way ANOVA was applied with sample divided into two groups (“up to 13 years” and “above 13 years”). Polynomial contrast was used to identify the type of tendency for cardiorespiratory fitness, and simple contrast for multiple comparisons. All procedures were performed using SPSS version 22.0 software, considering 5% significance level. In the “over 13 years” group, there was a significant effect on the cardiorespiratory capacity behavior according to “gender” [F(1, 45) = 5.54, p = 0.02, r = 0.33] and “age” [F(4.45) = 3.37, p = 0.02, r = 0.48]. The simple contrast identified increased cardiorespiratory fitness behavior in relation to age groups of 15 and 16 year when compared to the age group of 14 years. It was concluded that gender and age positively influence cardiorespiratory fitness from the maturational reference age in the study group.

This study examined factorial and other psychometric characteristics of the Positive and Negative Affect Schedule in relation to mixed-sex youth ( n: 234) and adult ( n: 436) samples. Broadly, the results for both age groups were supportive of commonly reported statistical properties of the schedule. Although two factors were plainly identified, they were not clearly endorsed for either age group by confirmatory indices of fit. Within the adolescent sample, sex differences in response to the scales were noted.
