目的:分析对妊娠少女进行人工流产医学干预的效果,探讨适合评价妊娠少女人工流产医学干预的效果指标。方法:通过奇偶号将500例样本分为参照组和干预组,进行为期1年的随访,采用统计学方法分析两组干预效果指标的差异性。结果:干预组的性和生殖健康知识提升分为(4.53±1.58),高于参照组的(2.31±0.68),差异有统计学意义(t=-17.830,P<0.05);干预组的流产后首次性生活避孕措施使用率为85.1%,高于参照组的60.7%,差异有统计学意义(χ2=22.911,P<0.01);两组避孕措施的使用频度构成比差异有统计学意义(χ2=33.527,P<0.01),参照组、干预组的无效避孕措施率减少百分比分别为24.4%、52.2%,干预组的频度提升幅度和无效避孕措施率减少百分比均优于参照组,且人工流产后1年内再次妊娠率(10.5%)低于参照组(18.5%),差异有统计学意义(χ2=3.905,P<0.05)。结论:医学干预对妊娠少女流产后的性和生殖健康知识得分、流产后首次性生活避孕措施使用、避孕措施使用频度、流产后1年内无效避孕措施率百分比和再次妊娠率等5个指标均有所改善。
OBJECTIVE: To analyze the effect of medical intervention on pregnant women in induced abortion and to explore the effect indexes of medical intervention suitable for evaluating induced abortion among pregnant women. Methods: 500 cases were divided into reference group and intervention group by parity. The patients were followed up for one year. Statistical analysis was used to analyze the difference of intervention effect between the two groups. Results: The improvement of sexual and reproductive health knowledge in the intervention group was (4.53 ± 1.58) higher than that in the reference group (2.31 ± 0.68), the difference was statistically significant (t = -17.830, P <0.05) The first contraceptive use rate was 85.1%, higher than 60.7% of the reference group, the difference was statistically significant (χ2 = 22.911, P <0.01). There was significant difference in using frequency of contraceptive measures between the two groups (χ2 = 33.527, P <0.01). In the reference group and the intervention group, the percentages of reduction in invalid contraceptive measures were 24.4% and 52.2%, respectively. The frequency of increase in the intervention group and the percentage reduction of invalid contraceptive measures were better than the reference group, The pregnancy rate again within one year after induced abortion (10.5%) was lower than that of the reference group (18.5%), the difference was statistically significant (χ2 = 3.905, P <0.05). Conclusions: The scores of knowledge about sexual and reproductive health of pregnant women after abortion by medical intervention, the use of first contraception after abortion, the frequency of contraception, the percentage of contraceptive measures within one year after abortion and the rate of re-pregnancy it has been improved.
