ABSTRACT

This study analyzed the anemia status and change trend of 219 835 pregnant women in eight provinces from 2016 to 2020 in the Maternal and Newborn Health Monitoring Program(MNHMP). The results showed that from 2016 to 2020, the anemia rate of pregnant women in eight provinces was 41.27%, and the rates of mild, moderate and severe anemia were 28.56%, 12.59% and 0.12% respectively; the anemia rates in eastern, central and western regions were 41.87%, 36.09% and 44.63% respectively, and the anemia rates in urban and rural areas were 39.87% and 42.23%. From 2016 to 2020, the anemia rate of pregnant women decreased from 44.93% to 38.22%, with an average annual decline of 3.86% (95%CI:-5.84%, -1.85%). The anemia rate among pregnant women of the eastern region (AAPC=-6.16%, 95%CI:-9.79%, -2.38%) fell faster than that among pregnant women of the central region (AAPC=0.71%, 95%CI:-6.59%, 8.57%) and western region (AAPC=-1.53%, 95%CI:-5.19%, 2.28%). From 2016 to 2020, the moderate anemia rate in pregnant women decreased from 14.98% to 10.74%, with an average annual decline of 8.72% (95%CI:-12.90%, -4.34%), with a statistically significant difference (P<0.05); AAPC for mild and severe anemia in pregnant women was 1.56% (95%CI: 3.44%, 0.36%) and 18.86% (95%CI: 39.88%, 9.52%), respectively, without statistically significant difference (P>0.05).

ABSTRACT

OBJECTIVE: This study aims to examine the association of menopausal status and symptoms with depressive symptoms. METHODS: A community-based cross-sectional survey recruited 6745 women aged 40-55 years in the eastern, central and western regions of China in 2018. Menopausal status was categorized into reproductive stage, perimenopause or postmenopause according to the Stages of Reproductive Aging Workshop classification. Menopausal symptoms were determined by the modified Kupperman Menopausal Index and classified as none (total score < 15), mild (15 ≤ total score ≤ 24) or moderate to severe (total score ≥ 25). Logistic regression models were used to examine the associations of menopausal status and symptoms with depressive symptoms assessed by the Patient Health Questionnaire-9. RESULTS: The prevalence of depressive symptoms among women in the reproductive stage, perimenopause and postmenopause was 15.4%, 23.9% and 22.8%, respectively. After multivariable adjustment, perimenopause (odds ratio [OR] = 1.21, 95% confidence interval [CI]: 1.01-1.47) and postmenopause (OR = 1.28, 95% CI: 1.04-1.58) were associated with higher risk for depressive symptoms than during the reproductive stage. Mild (OR = 5.55, 95% CI: 4.68-6.59) and moderate-to-severe (OR = 14.77, 95% CI: 10.94-19.94) menopausal symptoms were associated with increased likelihood of depressive symptoms compared to the group reporting no menopausal symptoms. CONCLUSIONS: Menopausal status and symptoms were independently associated with the risk of depressive symptoms in middle-aged Chinese women.

ABSTRACT

Objective: To analyze the effectiveness of the National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in China. Methods: Data were collected in the form of quarterly statistical tables reported by NCCSPRA counties in 30 provinces (Hong Kong, Macao and Taiwan province of China were not included into the NCCSPRA, and Tibet Autonomous Region carried out the program but did not reported the data) from 2009 to 2018. The women aged 35-64 years with sexual behavior and the identity (Hukou) of rural area in these project counties were included into the NCCSPRA, and women receiving hysterectomy for non-cervical cancer or non-cervical lesions were excluded. The following indicators were analyzed: the positive rates of different screening methods, the abnormality rates of colposcopy and histopathology, the detection rate of precancerous lesions, the detection rate of cervical cancer and the rate of early diagnosis. Results: A total of 85 041 490 women aged 35-64 in rural areas received free cervical cancer screening and diagnosis if necessary. On the whole, the abnormality rate of cytology, HPV testing, VIA/VILI, colposcopy and histopathology was 3.71%(2 567 610), 9.91%(331 158), 10.10%(1 167 930), 28.85%(1 420 847), and 21.20%(303 068) respectively. The detection rate of cervical precancerous lesions was 153.88/100 000, and increased from 106.85/100 000 in 2012 to 223.89/100 000 in 2018 (P<0.001). Regionally, the east (207.37/100 000) reached higher rate than the middle (177.65/100 000), and the middle higher than the west (108.65/100 000) (P<0.001). The detection rate of invasive cervical cancer was 21.58/100 000, and increased from 18.02/100 000 in 2012 to 26.54/100 000 in 2018 (P<0.001). Regionally, the middle of China (25.46/100 000) reached the higher rate than the east (19.62/100 000) and the west (19.30/100 000) (P<0.001). The rate of early detection was 91.24%(136 140), which increased from 89.60% (11 883)in 2012 to 92.80%(26 962) in 2018 (P<0.001). Regionally, the east of China (94.02%, 37 600) reached the higher rate than the middle(91.06%, 56 488), and the middle higher than the west (89.12%, 42 052) (P<0.001). Conclusions: There are obvious difference in terms of the detection rate of cervical precancerous lesions and the rate of early diagnosis reflecting cervical cancer screening capacity among the eastern, middle and western regions,which showed service inequity among different areas indirectly. The middle and western regions, especially the western regions, are still the focus of future works.

ABSTRACT

Objective: To evaluate the effectiveness and quality of ultrasound-based (BUS) process optimization in breast cancer screening. Methods: The program collected the first to fourth quarterly breast cancer screening statistic data and case report data from 30 provinces, autonomous regions and municipalities in 2015 by the online report system of national key service program of women and children's public health. The call rate, mammography (MG) subsequent screen rate, biopsy rate, detection rate, early diagnosis rate, carcinoma in situ rate, missing detection rate, false positive rate and positive predictive value (PPV) of breast cancer were calculated. Results: A total of 1 501 753 rural women attended the BUS process optimization screening. The nationwide recall rate was 3.01%(45 156/1 501 753), and in the eastern and central area were 3.41%(17 173/503 130) and 3.56%(14 499/407 739), respectively, higher than 2.28% (13 484/590 884) of western area (P<0.05). The nationwide MG subsequent screen rate was 2.78%(41 694/1 501 753), and in the eastern and central area were 3.19%(16 036/503 130) and 3.29% (13 421/407 739), respectively, higher than 2.07%(12 237/590 884) of western area (P<0.05). The nationwide biopsy rate was 0.23%(3 462/1 501 753), and in the central area were 0.26%(1 078/407 739), respectively, higher than 0.21%(1 247/590 884) of western area and 0.23% (1 137/503 130) of eastern area (P<0.05). The nationwide biopsy PPV was 37.00%(1 281/3 462). The biopsy PPV of eastern area was (34.30%, 390/1 137), lower than 39.33% (424/1 078) of central area (P<0.05). A total of 1 281 cases of breast cancer were detected, the detection rate was 0.85‰(1 281/1 501 753), and the detection rates of central area was 1.04‰ (424/407 739), higher than 0.79‰(467/590 884) of western area and 0.78‰(390/503 130) of eastern area (P<0.05). The BUS initiate screening positive rate from detected breast cancer cases was 96.96%(1 242/1 281), the MG subsequent screening positive rate was 2.42%(31/1 281). The nationwide early diagnosis rate was 85.25%(1 092/1 281), and in the eastern and central areas were 87.95%(343/390) and 88.21%(374/424), higher than 80.30%(375/467) of western area (P<0.05). The screening rate of on or above stage Ⅱ breast cancer in eastern area was 55.64%(217/390), lower than 64.62%(374/424) of central area and 62.31%(291/467) of western area. The missing detection rate was 0.62%(8/1 281) and false positive rate was 1.20%(17 528/1 464 149). Conclusions: The BUS process optimization of breast cancer screening scheme is reasonable and applicable to China rural women. The effectiveness and quality of eastern area are superior to those of central and western area.

ABSTRACT

Objective: To explore the epidemiologic characterization of high-risk human papillomavirus (HR-HPV) infection and genotype distribution of HR-HPV among women in rural areas of China. Methods: This study used multiple layers of stratified cluster random sampling method. During January to December in 2014, 117 counties of 27 provinces were selected as the HPV test screening pilot project counties. The women aged 35-64 years with rural areas Hukou in these project counties were selected as the study subjects. A total 457 799 women received HPV DNA test. Among them, 118 237 women from 32 counties in 11 provinces received qualified HPV DNA test by fluorescent PCR to detect HPV genotypes. Results: Among 118 237 rural women, the overall HR-HPV positive infection rate was 7.8% (9 249/118 237). The infection rate increased with age and reached an infection peak at the 60-64 age groups (9.9%, 831/8 394). The HR-HPV positive infection rate in western regions (6.9%, 2 144/31 130) was statistical significantly lower than in central regions (8.2%, 1 894/23 023) and eastern regions (8.1%, 5 211/64 084) (χ(2)=51.46, P<0.001). Among 9 249 women with specific genotypes of HR-HPV, 6 496 (97.6%) cases were infected with single HR-HPV type, and 163 cases (2.4% ) were infected with multiple types. HR-HPV type 52, 16 and 58 were the most common infection types in rural areas of China. The single infection rates were 20.9% (1 355/6 496), 18.7% (1 215/6 496), and 11.2% (725/6 496), respectively. The multiple infection rates were 47.2% (77/163), 17.8% (29/163), and 18.4% (30/163), respectively. Conclusion: The HR-HPV positive infection rate in rural areas of Chinese woman was 7.8%, western region has lower infection rate compared with central and eastern regions. HPV 52 was first of the most common genotypes in rural areas of China.

ABSTRACT

OBJECTIVE: To analyze the reported data of national rural cervical cancer screening project from 2012 to 2013 and to evaluate the project implementation condition. METHODS: Data of the national breast carcinoma and cervical cancer (two-cancer) screening project for rural women were collected from the online report system of key women and children's public health service programs.The screening items included: preliminary screening of cervical lesions (cervical cytology, using Traian Bethesda System(TBS) or Pap grading for classification and reporting), acetate/iodide staining (VIA/VILI), colposcopy, histopathological examination, and pathological diagnosis. The study collected the quarterly reported data from 1 183 counties of 30 provinces in 2014 and 1 130 counties of 30 provinces in 2013. Chi-square test was used to test the difference of positive detection rate, as well as precancerous cervical lesions, and cervical cancer detection rates among difference preliminary screening methods in 2012 and 2013. RESULTS: In 2012 and 2013, the number of cervical cancer screening was 10 621 482 and 10 321 835. The percentage of using ThinPrep cytological test as the screening method was 77.17% (n=8 196 627) and 77.07% (n=7 954 949) in 2012 and 2013, respectively. Among these ThinPrep cytological tests in these two years, 65.49% (n=5 368 194) and 71.67% (n=5 701 033) used TBS report system. The abnormality rate of colposcopy increased from 27.29% (170 063/623 161) to 31.15% (203 397/652 935) (χ(2)=2 295.94,P<0.001). The abnormality rate of histopathology test increased from 19.54% (37 992/194 394) to 35.43% (59 004/166 518) (χ(2)=11 523.58, P<0.001). All together, 27 341 cervical cancer or precancerous lesions have been detected in these two years. The detection rate of invasive cervical cancer increased from 18.02/100 000 in 2012 to 19.71/100 000 (χ(2)=7.90,P=0.005) in 2013 and that of precancerous lesions rose from 106.85/100 000 to 119.26/100 000 (χ(2)=70.82,P<0.001). The early detection rate was 89.60% (11 883/13 263), and 89.57% (12 609/14 078), respectively in 2012 and 2013. In these two years, the rank of the detection rate of each cervical lesion were CIN1, CIN2, CIN3, invasive carcinoma, adenocarcinoma in situ, and microinvasive carcinoma, from the highest rate to the lowest rate. CONCLUSION: The program has achieved certain screening effect and the screening method has been improved. However, the quality of colposcope and histopathology should be enhanced.
