The progress of myopia in children is related to the reproductive age of mothers

Abstract: they were divided into four groups according to their parents’ childbearing age, The diopter of children whose mothers have older childbearing age changes more (trend test, P = 0.04), however, there is no significant correlation between the change of myopia diopter and the age of the father. Myopia is the most common factor affecting children’s vision in Asia. Although there are a large number of studies, the exact cause of myopia is still unclear. It is reported that the increase of parental childbearing age is a possible risk factor for the progression of myopia, which is consistent with the increasing trend in the world The trend of myopia was consistent. The family planning policy has been Chinese mainland for over 30 years, and the phenomenon of late marriage and late childbirth is very common, especially in China’s city areas. Professor Liang Yuanbo and his team investigated the relationship between the progress of ametropia and the childbearing age of parents in Beijing. They found that the older the childbearing age of mothers, the faster the progress of myopia of children may be., Objective: To investigate the relationship between the development of ametropia and maternal childbearing age of students in Beijing., Methods: Pupils’ initial visual acuity and follow-up visual acuity were examined by mydriatic optometry, and their parents’ visual acuity was examined by non mydriatic optometry. The diopter changes of students were obtained by subtracting the baseline diopter from the right eye mydriasis equivalent spherical mirror (SE) after follow-up. Results: in the final follow-up, 241 students completed the 3-year follow-up, 226 students (93.8%) had complete diopter data and complete parental childbearing age data registration. The average age of father and mother ranged from 29.4 to 27.5 years (1993-1994) increased to 32.6 years old and 29.2 years old (2003-2004). Multivariate analysis results of young students( β= 0.08 diopter, P < 0.001), initial high diopter( β= 0.02 diopter, P = 0.01), and the mother's childbearing age was high( β=- 0.18 diopter, P = 0.01), with more diopter changes. They were divided into four groups according to their parents' childbearing age, There were more changes in diopter in children with older maternal childbearing age (trend test, P = 0.04). However, there was no significant correlation between the change of myopia diopter and father's age Myopia is the most common factor affecting children's vision in Asia. Although there are a lot of studies, the exact cause of myopia is still unclear. It is reported that the increase of parental childbearing age is a possible risk factor for the progression of myopia, which is consistent with the increasing trend of myopia in the world.

They found that the older the childbearing age of mothers, the faster the progress of children's myopia may be.

objective: To investigate the relationship between the progress of ametropia and the childbearing age of mothers among students in Beijing.

methods: mydriatic optometry was performed for students’ initial visual acuity and follow-up visual acuity, and non mydriatic optometry was performed for their parents’ visual acuity. The diopter changes of students were obtained by subtracting the baseline diopter from the right eye mydriasis equivalent spherical mirror (SE) after follow-up.

results: in the final follow-up, 241 students completed the 3-year follow-up, 226 students (93.8%) had complete diopter data and complete parental childbearing age data registration. The average age of father and mother ranged from 29.4 years to 27.5 years (1993-1994) increased to 32.6 years old and 29.2 years old (2003-2004). Multivariate analysis results of young students( β= 0.08 diopter, P < 0.001), initial high diopter( β= 0.02 diopter, P = 0.01), and the mother's childbearing age was high( β=- 0.18 diopter, P = 0.01), with more diopter changes. They were divided into 4 groups according to their parents' childbearing age. Children with older childbearing age had more diopter changes (trend test, P = 0.04). However, there was no significant correlation between the change of myopia diopter and the father's age.
