Age Of Menarche

INTRODUCTION : Various studies indicate that the average age of menarche has decreased significantly in the last 150 years, which there has been a secular (time-related) trend towards an earlier onset of menarche in most developed countries. In recent years, such a decline has also been observed in developing countries like India. The purpose of the present study was to asses the effect of food and social status on age of menarche in this region. METHODS: Study included 200 girls of age group between 9 to 14 on Voluntary basis after Simple Random Sampling around the schools . After obtaining permission and consent from the school Principal/ class teacher, a predesigned questionnaire was administered and girls were briefly examined by a female doctor. . Detail information about girls and their parents were taken to know the mother’s age at menarche and also to know the socioeconomic status of the family along with other details. RESULTS: Our study shows that age at menarche in higher socioeconomic classes is lower as compare to Lower Socioeconomic class. No significant association between BMI & type of food and average age of menarche was found in our study. CONCLUSIONS: The trend of lowering of age at menarche is well marked as we moved from lower and middle to higher socioeconomic stratum. There is paucity on such data from this region of India; hence further study needs to be done among girls from other areas of the state before the data can be extrapolated to the Indian statistics.

Menarche Age

Introduction: Several studies have found that the most common age of menstruation onset has come down dramatically over the previous century, and that there has been a profane (with respect to time) tendency toward early menstruation onset in most metropolitan countries. Emerging economies, such as India, have also suffered a drop in recent years. The purpose of our study was to determine how diet and socioeconomic status influenced menarche age in this location. Methods: Following a simple random sampling among the schools, 100 girls between the ages of 10 and 15 were volunteered for this study. The girls were given a pre-designed questionnaire after receiving clearance and agreement from the school principal/class teacher. The female doctor gave the girls a brief examination. The age of the mother during menarche, as well as the family's socioeconomic situation and other characteristics, were all enquired about in depth. Results: Our study shows that the age of onset of menstruation in higher socioeconomic classes is lower as compared to Lower Socioeconomic class. No significant relation between BMI & type of food and usual age of onset of menstruation was seen in this study. Conclusions: As we progress from a lower to a better socioeconomic level, we see a trend of lowering the age of first menstrual flow. Because such data is scarce in this portion of India, more research must be conducted among girls from other parts of the state before the data can be compared to national figures.

Background: Present study highlights that the worldwide trend of declining age at menarche is also seen in urban Indian girls. The aim of the study was to evaluate the age of menarche and to find out the factors associated with the timing of menarche.Methods: The study was an observational cross sectional study. 258 healthy, menstruating, adolescent girls aged 10-16 years, were selected by simple random sampling. Pre-designed structured questionnaires were distributed after taking informed consent. Anthropometric measurements were taken using standard techniques. The average age of menarche was calculated. The association of the age at menarche with the proposed factors was analyzed using chi square test and Pearson’s correlation coefficient. “P value” less than 0.05 was considered as significant.Results: The mean age at menarche was found to be 12.23±1.09 years. The study found a strong association between the respondent’s age at menarche and her sister’s age at menarche (p=0.002). The study also found a strong association between age at menarche and the socioeconomic status (p=0.021). This study however found no association of menarcheal age with factors like birth weight, type of diet, frequency of milk intake, body mass index, waist hip ratio, amount of exercise, unstable environment at home and psychosocial stress.Conclusions: The worldwide trend of declining age at menarche is also seen in urban Indian girls. This trend underlines the importance of investigating the factors associated with it and studying the future implications of a lower age at menarche.

INTRODUCTION: In this study, we aimed to determine the range of mean age at onset of menarche (AOM) and puberty (AOP) of girls living in Aydin province and to determine the factors affecting the onset age of menarche. METHODS: A total of 1891 girls aged between 8 and 16 years attending primary, secondary and high schools in Aydin province were planned to be included in the study. A questionnaire that was prepared in line with the literature was delivered to the parents in a closed envelope. The subjects who accepted to participate in the study were examined by an experienced physician by measuring height and weight and pubertal status was defined according to Tanner scale. BMI values were calculated. RESULTS: In total, 1520 female students were accepted to the study with the permission of their families. The mean AOM of participants was 12.11±1.32 years. The mean AOM was 13.12±1.46 years for their mothers, and 12.73±1.25 years for their sisters. June was the month that menarche occurred most frequently. We observed that the children living in rural areas had an earlier age of menarche. The mean age at onset of puberty was 9.71±1.46 years. DISCUSSION AND CONCLUSION: Our study is important in terms of being the first study conducted in Aydin province that determined the mean AOM and AOP of girls aged between 8 and 16. In our study, we showed that the age of menarche shifted to an early age, while the age of puberty did not shift. The age at onset of menarche and puberty were similar to the results obtained in other studies conducted in neighboring regions. We believe that larger scale studies may contribute to assess the actual mean age at menarche of girls living in Turkey.

Abstract Sustainable economic growth and identifying factors affecting it are among the important issues which have always received attention from researchers of different countries. Accordingly, one of the factors affecting economic growth, which has received attention from researchers in the developed countries over recent years, is the issue of environmental technologies that enter the economic cycle of other countries after being patented through technology transfer. The current research investigated the role of the environment-related patents and the effects of the patented technological innovations compatible with climate change mitigation on the economic growth and development in the Middle East countries within a specific time period. The required data were gathered from the valid global databases, including Organization for Economic Co-operation and Development and World Bank and have been analyzed using multi-linear regression methods and econometric models with Eviews 10 software. The obtained results with 95% confidence level show that the environmental patents (β = 0.02) and environment management (β = 0.04) and technologies related to the climate change mitigation (β = 0.02) have a significant positive impact on the sustainable economic development and growth rate in the studied countries. Such a study helps innovators and policymakers in policy decisions related to sustainable development programs from the perspective of environmentally friendly technologies by demonstrating the role of patents in three important environmental areas, namely environmental management, water-related adaptation and climate change mitigation, as one of the factors influencing sustainable economic growth.

Abstract The main aim of the study was to examine the role of females' economic participation in household income. To achieve this objective both primary and secondary sources of data were collected from 400 sample size using simple random sampling method. The obtained data were first analyzed using a descriptive method to describe socio-economic characteristics of women in the study area. Secondly, to identify determinants of women’s participation in economic activities and household decision-making process logit model was employed and finally, multiple linear regression method was applied to identify factors affecting the level of women's contribution to household income. The result shows that female participation in economic activities positively determines by women's training and woman’s education level and is negatively affected by the presence of children under five years of age. The contribution of women to household income on average was estimated birr 32,400.50 per annum which was nearly 36.8percent of the overall household income. The possible recommendation is government and other respective bodies must encourage women to learn more and more.

Abstract The aim of the research was to determine the prevalence of non-pathogenic protozoa circulating in the human population of Slovakia. We particularly focused on the socially deprived areas with poor sanitation conditions, as they are one of the factors affecting the transmission of these infections. Within this study, 2760 people were coprologically screened for the presence of protozoan cysts. The analyzed group comprised 1173 men and 1587 women from different regions of Slovakia. The total prevalence (2.03%) of non-pathogenic protozoa species was determined. The prevalence of Entamoeba coli was 0.80%, the prevalence of Endolimax nana 0.58%, and the prevalence of Blastocystis hominis was 0.65%. The presence of non-pathogenic protozoa was more frequent in women than that in men, in all age groups. The highest incidence of Entamoeba coli was found in children aged one month – seven years (0.79%), the lowest in the age group of 19–88 years (0.66%). Endolimax nana was most frequent in 8–18 year-olds (0.95%), where the statistical significance was found (p<0.05). The prevalence of Blastocystis hominis by the age group ranged from 0.39 to 0.95%. We did not find any statistical significance (p>0.05) for Entamoeba coli, and similarly for Blastocystis hominis associated with the sex and age. Although the circulation of non-pathogenic protozoa in the human population is far from being limited to the developing countries, their occurrence is also frequent in the population of developed countries. Despite their controversial pathogenicity, they should not be neglected, particularly in the patients with gastrointestinal symptoms.

Although macroeconomics as an independent economic science emerged only in the twen­tieth century, the first steps in developing the macroeconomic aspect of efficiency were taken several centuries earlier — beginning from the 16th — 17th centuries — at the pre-industrial stage of development of society. Due to the underdevelopment of the production sphere, the search for sources of growth in the efficiency of national economies at that time was mainly carried out from the most general economic positions — as an integral part of solving the main task of the economics of those eras — searching for ways and means of increasing the wealth of nations. At the same time, naturally, among the first were the climatic and foreign economic factors of increasing the efficiency of national economies. For example, factors related to identifying the advantages of various countries in a geographic location and the ability to solve their economic problems by using the most advantageous options for organizing and conducting foreign economic and trade relations. The transition of developed countries to new stages of development — industrial and postindustrial, as well as the selection by John M. Keynes of the new direction of economic research — macroeconomics, historically leads both to a deepening of the meaning of the very category of “macroeconomic efficiency” and to more detailed studies of factors affecting it.
