Journal of Preventive Medicine 2022;34(10):1048-1052
Objective:
To investigate the perinatal mortality and its causes in Lishui City, Zhejiang Province, so as to provide insights into the reduction of perinatal mortality.
Methods:
The perinatal mortality data were collected from three designated monitoring counties (districts) in Lishui City from 2015 to 2020. The changing trend in perinatal mortality and causes of death were analyzed, and the differences of perinatal causes of death and maternal conditions in urban and rural areas were compared.
Results:
There were 406 perinatal deaths in three monitoring counties (districts) of Lishui City from 2015 to 2020. The perinatal mortality showed a downward trend (χ2trend=5.078, P=0.024), and the average perinatal mortality rate was 5.93‰. The top five causes of perinatal mortality were birth defects, unknown causes, umbilical cord factors, maternal factors and preterm delivery. There was significant difference in the causes of perinatal death between urban and rural areas (χ2=25.574, P<0.001); birth defects, umbilical cord factors and unknown causes were predominant in urban areas, accounting for 75.00% (138 deaths); while birth defects, unknown causes and maternal factors were predominant in rural areas, accounting for 67.57% (150 deaths). The proportion of junior high school education and below was significantly higher in rural women than in urban women with perinatal death (54.50% vs. 26.63%; χ2=32.117, P<0.001), and the proportion of more than 5 antenatal examinations was significantly lower in rural women than in urban women with perinatal death (46.85% vs. 59.24%; χ2=6.195, P=0.012).
Conclusions
The perinatal mortality appeared a tendency towards a decline in Lishui City from 2015 to 2020, and birth defect was the main cause. Prenatal and postnatal care and tertiary prevention should be strengthened.

The present study aimed to investigate the impact of hypothyroidism on left ventricular systolic function using real-time three-dimensional speckle tracking imaging (RT3D-STI). Thirty hypothyroidism patients and forty healthy volunteers were recruited and received RT3DSTI measurement of global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS). A comparison of differences between the hypothyroidism patients and those in the healthy group was carried out and we obtained the results as followings. The values of GLS were (-18.93 +/- 3.89) vs. (-21.44 +/- 1.99), with P < 0.01, GRS were (51.13 +/- 11.95) vs. (56.10 +/- 5.76), with P < 0.0; and GAS were (-31.63 +/- 5.38) vs. (-34.40 +/- 2.32), with P < 0.01, i.e. they were lower in hypothyroidism group than those in the health group. While GCS were (-17.75 +/- 1.92) vs. 17.03 +/- 3.45), with P > 0.05, which were not significantly different between the two groups. In linear regres sion, GLS showed significant correlation with both TSH (b = -0.69, P < 0.01) and FT3 (b = 0.71, P < 0.01). Meanwhile, the GRS (b = 2.98, P < 0.05) and GAS (b = 3.11, P < 0.05) linearly correlated with FT3 level. In conclusion, the present study shows that the global longitudinal and radial moves of left ventricular are weaker in patients with hypothyroidism than healthy controls. And the impairment of left ventricular function would aggravate as FSH rises or FT3 declines.
