[Logistic regression analysis of influential factors on auditory receptive and auditory expressive language...

To identify the influential factors on auditory receptive and auditory expressive language development and to provide clues to avoid language delay.

A questionnaire was conducted among the caregivers of 2794 2-year old healthy children selected by cluster sampling in subdistricts with middle economic level from randomly selected 8 districts of Shanghai by using the "Early language milestone scale". Logistic regression analysis was used to find out the related factors.

Five of the 24 items were the risk factors for the expressive language development: seldom practicing speaking (OR = 3.0257), reading quietly (OR = 2.0704), being male (OR = 1.7778), watching TV without discussing (OR = 1.4424), beginning to read after the age of 1.5 years (OR = 1.1576 - 2.0115). Eleven of the 24 items were the risk factors for the receptive language development: father's physical labor occupation (OR = 17.0238), seldom practicing speaking (OR = 2.8410), living in city (OR = 2.0125), reading quietly (OR = 1.7039), watching TV for more than 2 hours a day (OR = 1.6551), watching TV without discussing (OR = 1.5344), lack of communication between children and caregiver (OR = 1.1892), mother's bad education (OR = 1.1870), being male (OR = 1.6722), seldom playing with other children n (OR = 1.1671), beginning to read after the aged of 1.5 years (OR = 1.0435 - 2.0228).

There are different factors related to 2-year-old children's receptive and expressive language development. Avoiding the risk factors and providing rich language environment would help prevent and intervene the language delay in early life.
