Methods A retrospective analysis was made on the perinatal year report of Wenjiang District from 2009 to 2012. The χ2 test of two sample rates was used to understand the trend of each index. Results A total of 17 421 perinatal infants were born in Wenjiang District from 2009 to 2012, of whom 152 were elderly women, accounting for 6.61% of the total. The overall changes in the past four years were not significant, but the urban areas were higher than those in rural areas (χ2 = 8.669, P <0.05) (Χ2 = 3.969, P <0.05). There were 664 young women with a ratio of 3.81%, showing an overall downward trend. The rural areas were higher than the urban areas (χ2 = 153.088, P <0.05) (Χ2 = 4.606, P <0.05).
