ABSTRACT
Objective:To study the genetic variation and distribution characteristics of thalassemia in people of childbearing age in Hubei Province, and to provide clinical basis for the local government decision-making departments to formulate and promote appropriate policies for prevention and control of thalassemia.Methods:Venous blood samples were collected from 44 849 people of childbearing age in hospitals in Hubei Province from May 13, 2019 to August 17, 2021. PCR-flow fluorescence hybridization and PCR+diversion hybridization were used to screen thalassemia genes. Spouses of those who tested positive were also tested for thalassemia genes. When both spouses carried the same type of thalassemia gene, the amniotic fluid of pregnant women was extracted for prenatal diagnosis and followed up.Results:Among the 44 849 people of childbearing age, 2 286 cases were diagnosed as thalassemia gene carriers through genetic testing, and the total detection rate was 5.10% (2 286/44 849). Among them, 1 488 cases were diagnosed as α-thalassemia, and the detection rate was 3.32% (1 488/44 849); 767 cases were diagnosed as β-thalassemia, and the detection rate was 1.71% (767/44 849); 31 cases were diagnosed as α-thalassemia combined with β-thalassemia, and the detection rate was 0.07% (31/44 849). The top three genotypes of α-thalassemia were -α 3.7/αα, -- SEA/αα, and -α 4.2/αα, accounting for 58.06% (864/1 488), 26.14% (389/1 488), and8.74% (130/1 488), respectively. The top three genotypes of β-thalassemia were β IVS-Ⅱ-654/β N, β CD41-42/β N, and β CD17/β N, accounting for 41.72% (320/767), 21.25% (163/767), and 16.04% (123/767), respectively. The main genotypes of α-thalassemia combined with β-thalassemia were -α 3.7/αα complex β IVS-Ⅱ-654/β N and -α 3.7/αα complex β CD41-42/β N, accounting for 29.03% (9/31) and 16.13% (5/31), respectively. A total of 59 people of childbearing age were conducted prenatal diagnosis, among fetus, there were 4 cases of severe thalassemia (2 cases of severe α-thalassemia, 2 cases of severe β-thalassemia), 5 cases of intermediate α-thalassemia, 5 cases of intermediate or severe β-thalassemia, 19 cases of mild thalassemia (8 cases of mild α-thalassemia, 11 cases of mild β-thalassemia), 13 cases of stationary α-thalassemia, and 1 case of stationary α-thalassemia combined with mild β-thalassemia, there were 12 cases without α-thalassemia or β-thalassemia genes. After follow-up, 4 cases of severe thalassemia, 2 cases of intermediate α-thalassemia, and 5 cases of intermediate or severe β-thalassemia were terminated pregnancy by the joint decision of both parents. Conclusions:In Hubei Province, the detection rate of thalassemia is high, and α-thalassemia is the main mutation type. The combination of thalassemia gene screening and prenatal diagnosis is of great significance in reducing the birth rate of children with thalassemia.
ABSTRACT
Objective@#To investigate the factors affecting decreased ovarian reserve (DOR) among women of childbearing age, so as to provide insights into prevention of DOR.@*Methods@#Women with DOR at ages of 18 to 40 years that were admitted to Department of Gynecology, Ningbo Women and Children's Hospital during the period from January 2021 to June 2022 were recruited (DOR group), while healthy women at ages of 18 to 40 years during the same period served as normal controls. Participants' demographics, exercise, diet, previous medical history, childbearing history and menstruation were collected using questionnaire surveys. The follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH) and estradiol (E2) levels were tested. Factors affecting DOR were identified among women of childbearing age using a multivariable logistic regression model.@*Results@#There were 200 participants in the DOR group, with a median (interquartile range) age of 32 (9) years, and 200 participants in the normal group, with a median (interquartile range) age of 29 (12) years. Multivariable logistic regression analysis showed that underweight (OR=2.935, 95%CI: 1.374-6.269), overweight/obesity (OR=2.612, 95%CI: 1.335-5.065), high-oil-high-glucose-high-salt diet (OR=2.653, 95%CI: 1.616-4.357), menstrual disorder (OR=1.977, 95%CI: 1.284-3.041) and lack of exercise (OR=3.392, 95%CI: 2.052-5.606) were statistically correlated with the development of DOR among women of childbearing age.@*Conclusions@#Underweight, overweight/obesity, high-oil-high-glucose-high-salt diet, menstrual disorder and lack of exercise are factors affecting the development of DOR among women of childbearing age.

OBJECTIVE@#To explore the genotypes and prenatal diagnosis of thalassemia in couples of childbearing age in Quanzhou, Fujian Province.@*METHODS@#Blood routine and hemoglobin electrophoresis were performed for initial thalassemia screening in 76 328 couples in Quanzhou region from July 2017 to July 2020. The couples with positive initial screening results further underwent thalassemia gene test. Couples carrying homotypic thalassemia genes underwent prenatal diagnosis in the second trimester.@*RESULTS@#Among 76 328 couples of childbearing age, 1 809 couples of positive initial thalassemia screening were identified, with the positive rate about 2.37%. Further results of genetic detection of the 1 809 couples showed that 985 cases were diagnosed as α- thalassemia, of which --sea/αα was the most frequency, followed by -α3.7/αα and ααQS/αα; 296 cases were diagnosed as β-thalassemia, the most frequency mutations were 654M/N and 41-42M/N; 26 cases of compound α and β-thalassemia were detected. In addition, 3 rare cases of thalassemia were detected, including --THAI/αα, SEA-HPFH, and -α6.9/--sea. Among them, 108 couples were confirmed as homologous thalassemia, with the detection rate about 5.97%, including 96 couples of homologous α-thalassemia, 9 couples of homologous β-thalassemia, and 3 couples with one had compound α- and β-thalassemia. Among them, 17 couples with homologous α-thalassemia underwent prenatal diagnosis in the second trimester, of which 1 case of Hb Bart's Hydrops Syndrome, 3 cases of HbH disease, 9 cases of silent thalassemia or α-thalassemia minor, and 4 cases of healthy fetuses were detected. Fetal chromosome karyotype analysis showed that 16 cases were normal and 1 case diagnosed as Down syndrome.@*CONCLUSION@#Thalassemia screening in pre-marital and pre-pregnancy, and prenatal diagnosis can effectively reduce the birth of children with thalassemia intermediate and thalassemia major. It is necessary to perform chromosome karyotype analysis at the same time as prenatal diagnosis of thalassemia gene in order to avoid fetus with abnormal chromosome.

Objective:To investigate the fertility intention and psychological pressure of women of childbearing age in Yanshan County, Jiangxi Province, and to provide data support for the targeted promotion of fertility.Methods:Using the method of random sampling, women of childbearing age in 10 communities in Yanshan County, Jiangxi Province were given questionnaires and psychological stress rating tables to understand the basic information, the status of marriage and childbearing, childbearing intentions, and the Chinese version of the Perceived Stress Scale (CPSS) score, and explore the related factors that may affect childbearing intentions and psychological stress of women of childbearing age.Results:In this survey, 1 500 questionnaires were distributed to women of childbearing age, 913 of which were returned, and 65.0%(593/913) of them were willing to have children. The CPSS score of women of childbearing age was 8-28(16.84±2.75). The CPSS scores of women of childbearing age in different occupations were statistically significant ( P<0.05). Public officials (including civil servants and employees of public institutions) had the least psychological pressure, while self-employed and other (unemployed) had the most psychological pressure. There was no significant difference in CPSS scores among women of childbearing age with different education levels, annual income levels, marital status and willingness to have children (all P>0.05). The correlation analysis showed that there was a statistical significance between the psychological pressure of women of childbearing age and their occupation ( r=0.230, P<0.05), and there was no significant correlation between other factors such as education level, annual income, fertility desire, fertility status, etc. and psychological pressure (all P>0.05). Conclusions:The fertility intention desire of women of childbearing age in Yanshan County, Jiangxi Province is basically normal, and the desire to have more children is not strong. There is no significant correlation between fertility intention and psychological pressure. The psychological pressure of women of childbearing age is significantly related to their occupation.
ABSTRACT
Background: Dietary exposure to mercury in women of childbearing age could result in neurological effects on the fetus. A health risk assessment of total mercury by fishery products intake has not been conducted in this population group in Bogota, Colombia. On the other hand, it has been suggested that selenium content on fishery products may have a protective effect against mercury toxicity. Nevertheless, selenium content on fish species marketed in Bogota has not been determined. Objective: Exposure risk to total mercury and selenium content on fishery products consumed by women of childbearing age from Bogota, Colombia, were assessed. Methods: Total mercury and selenium concentrations for products available at fish stores and supermarkets were determined. The exposure risk to total mercury was estimated considering the intake of these products by women of childbearing age group. Results: Total mercury highest concentrations were 0.8166 mg/kg in mota (Calophysusmacropterus), and 0.6275 mg/kg in catfish (Pseudoplatystoma tigrinum). On the other hand, the highest selenium concentration was 0.6471 mg/kg in nicuro (Pimelodus blochii). Finally, it was established that for women of childbearing age group, health risk of exposure to total mercury due to mota intake exceeded by 8.56-fold the reference dose. Conclusions:Mota intake considerably increases exposure risk to total mercury on women of childbearing age from Bogota, Colombia. The selenium levels established in the fishery products assessed, except for catfish and mota, are theoretically suggestive of a protective effect of selenium against mercury toxicity. Consequently, continuous total mercury concentrations monitoring is required to protect health of women of childbearing age and the general population from Bogota, Colombia
Antecedentes: La exposición dietética al mercurio en mujeres en edad fértil podría provocar efectos neurológicos en el feto. En Bogotá, Colombia no se han realizado evaluaciones de riesgo por la exposición al mercurio total debido a la ingesta de productos de la pesca en este grupo de la población. Por otro lado, ha sido sugerido que el contenido de selenio en los productos de la pesca podría tener un efecto protector frente a la toxicidad por mercurio, sin embargo, el contenido de selenio en las especies de peces comercializadas en Bogotá, Colombia no ha sido determinado. Objetivo: Evaluar el riesgo de exposición al mercurio total y el contenido de selenio en los productos de la pesca consumidos por las mujeres en edad fértil de Bogotá, Colombia. Métodos: Se determinaron las concentraciones de mercurio total y selenio en distintos productos de la pesca disponibles en pescaderías y supermercados. El riesgo de exposición a mercurio total se estimó considerando la ingesta de estos productos por parte de un grupo de mujeres en edad fértil. Resultados: Las concentraciones más altas de mercurio total fueron de 0.8166 mg/kg en mota (Calophysus macropterus) y 0.6275 mg/kg en bagre (Pseudoplatystoma tigrinum). Por otro lado, la concentración más alta de selenio fue de 0.6471 mg/kg en nicuro (Pimelodus blochii). Finalmente, se estableció que el riesgo de exposición a mercurio total, debido a la ingesta de mota, excedió en 8.56 veces la dosis de referencia en el grupo de mujeres en edad fértil. Conclusiones: La ingesta de mota aumenta el riesgo de exposición al mercurio total en las mujeres en edad fértil de Bogotá, Colombia. Por otro lado, los niveles de selenio identificados en los productos evaluados, excepto en bagre y mota, teóricamente sugieren un posible efecto protector del selenio contra la toxicidad por mercurio. Considerando lo indicado, es necesario realizar un monitoreo continuo de las concentraciones de mercurio total en los productos de la pesca, con el fin de proteger la salud de las mujeres en edad fértil y de la población general de Bogotá, Colombia

RESUMEN Propósito: Relacionar la ingesta dietaria de hierro con el estado nutricional de éste en una muestra de mujeres en edad fértil de Santiago de Chile. Método: A 51 mujeres entre 18 - 35 años se aplicó una Encuesta de Tendencia de Consumo para estimar el aporte de hierro dietario, junto con la medición de los biomarcadores bioquímicos a modo de determinar el estado de los depósitos de hierro. Mediante prueba estadística de Mann-Whitney se analizaron diferencias significativas entre los grupos según estado nutricional del hierro y sus parámetros sanguíneos. Resultados: Treinta y siete de las participantes (72,5%) no cumple con la ingesta recomendada de hierro diario. Dos de las mujeres presentaron anemia, 2 deficiencia de hierro sin anemia y 12 tenía los depósitos de hierro depletados. Tres de las mujeres que presentaron depósitos deficientes tuvieron una ingesta de hierro adecuada, mientras que el 71% de las mujeres con depósitos normales presentaron una ingesta de hierro insuficiente. Conclusiones: Hay un bajo cumplimiento de los requerimientos diarios de hierro y no se observan mejores valores hematológicos a mayor ingesta de hierro, a pesar de presentar un alto porcentaje con depósitos normales de hierro. Se requiere mayor análisis de la alimentación de este grupo de la población para identificar el tipo de hierro que se está aportando principalmente y si hay otros factores dietarios y no dietarios afectando los depósitos de hierro.
ABSTRACT Objectives: To relate dietary intake of iron with iron status in a sample of women of childbearing age from Santiago de Chile. Methods: A Food Frequency Survey was applied to 51 women between 18 - 35 years of age to estimate intake of dietary iron, together with the measurement of biochemical biomarkers to determine iron stores. Using the Mann-Whitney statistical test, significant differences were analyzed between the groups according to nutritional status of iron and its blood parameters. Results: Thirty seven of the participants (72.5%) do not meet the recommended daily iron intake. Two had anemia, 2 had iron deficiency without anemia, and twelve had depleted iron stores. Three women with deficient iron stores had an adequate iron intake, while 71% of women with normal iron stores showed an insufficient iron intake. Conclusions: We observed a low compliance with the daily iron requirements and no better hematological values were associated with higher iron intake, despite a high percentage of women with normal iron stores. To identify the type of iron mainly contributed by the diet and if there are other dietary and non-dietary factors affecting iron stores, further analysis of this population group is required.
ABSTRACT
Objective:To analyze the serum anti-Müllerian hormone (AMH) levels in women of childbearing age in different age groups in Henan, and establish the medical reference intervals based on measurement results from this population.Methods:From January to June 2017, 620 healthy women of childbearing age (20-34 years old), who underwent pre-pregnancy eugenics and pre-marital checkups in 13 project sites in Henan, were included in this study. Participants were divided into 3 age groups: 20-24 years group ( n=210), 25-29 years group ( n=207), and 30-34 years group ( n=203). Spearman correlation coefficient was used to evaluate the correlation between serum AMH level and age; Kruskal-Wallis H test was used to compare the serum AMH levels of different age groups; Wilcoxon test was used for comparison between pairs; the percentile method ( P2.5, P97.5) was used to establish medical reference interval of serum AMH in women of childbearing age for the whole population and different age groups, respectively. Results:The correlation coefficient between serum AMH and age in women of childbearing age (20-34 years old) is -0.17 ( P<0.001). There was a statistically significant difference in the overall frequency distribution of serum AMH levels among the three different age groups ( H=21.978, P<0.05). Among them, there is a statistically significant difference between the 20-24 years group and the 30-34 years group ( Z=4.292, P<0.05). There is a statistically significant difference between the 25-29 years group and the 30-34 years group ( Z=3.803, P<0.05). The reference range of serum AMH is 0.281-9.693 μg/L in this cohort; the reference range of serum AMH is 0.524-10.760, 0.229-9.200, 0.115-8.200 μg/L for women of childbearing age at 20-24, 25-29 and 30-34 years, respectively. Conclusion:The serum AMH level of women of childbearing age (20-34 years old) decreases with age. It is of great significance to establish the serum AMH reference interval for women of childbearing age in different age groups in Henan.
ABSTRACT
Objective To explore the epidemiology of human papillomavirus infection in women of childbearing age in Shaanxi Province. Methods A stratified random sampling method was used to select 16705 patients under childbearing age in Shaanxi from January 2015 to January 2020, and 857 healthy patients who had physical examination during the same period were selected as the control group. The general information of patients was obtained through questionnaire survey, and the risk factors were analyzed by single factor and multivariate logistic analysis. Results The detection rate of human papillomavirus infection in 16705 cases was 2570 (15.38%), of which 1972 cases of high-risk type (11.80%) were higher than 598 cases (3.58%) of low-risk type (χ2: 795.77, P 2: 259.08, P <0.001).The proportions of younger than 30 years old, sexual life ≥3 times/week, no condoms, cervical erosion, and smoking were higher in high-risk human papillomavirus infection group than the control group (P<0.05). After multivariate logistic regression analysis, the results showed that the frequency of sexual life and the greater degree of cervical erosion were independent risk factors for high-risk human papillomavirus infection [OR (95% CI): 3.112 (1.607~7.702), 4.209 (2.338~ 12.526, P<0.05], the use of condoms is a high-risk protective factor for human papillomavirus infection [OR(95%CI): 0.674 (0.578~0.699, P<0.05]) Conclusion The frequency of sexual life and the degree of cervical erosion are high in women of childbearing age in Shaanxi. The use of condoms can effectively prevent human papillomavirus infection. Reasonably formulating effective intervention measures and vigorously publicizing the knowledge of human papillomavirus prevention and treatment is the key to reducing human papillomavirus infection in women of childbearing age in Shaanxi.
ABSTRACT
ABSTRACT Background The recognition of the causal association between Zika virus (ZIKV) infection during pregnancy and congenital abnormalities including microcephaly underlines the importance of preventing this disease in pregnant women (PW) and women of childbearing age (WCA). Although Brazil and other Latin American countries reported a significant reduction in the number of ZIKV infections in recent years, epidemic waves can recur in settings with previous outbreaks as conditions for transmission remain optimal and susceptible populations are continuously replenished. Methods: In this cross-sectional study, we enrolled 64 PW and 260 non-pregnant WCA attending routine medical appointments in two primary care units in São Paulo, Brazil, and assessed knowledge and attitudes about ZIKV infection and prevention. Results: Most women reported knowing that ZIKV is transmitted through the bite of Aedes mosquitos, and most knew that acute symptoms are similar to those seen in Dengue infection. Furthermore, most participants correctly described that ZIKV infection during pregnancy may cause detrimental outcomes for the newborn. However, most ignored that ZIKV infection can be asymptomatic, and only 15% knew about the risk of ZIKV sexual transmission. We found no statistically significant differences between PW and WCA regarding knowledge about ZIKV sexual transmission. Knowledge about ZIKV sexual transmission was significantly associated with education; among participants with ≤12 schooling years, only 9.0% (95%CI 3.4-18.5%) correctly answered that ZIKV can be sexually transmitted, compared to 12.9% (95%CI 8.2-18.8%) among participants with 12-14 schooling years, and to 24.4% (95%CI 15.9-34.9%) of participants with ≥15 schooling years (p = 0.015). Education remained independently associated with knowledge about sexual transmission of ZIKV in a multivariate logistic regression model adjusted for age, race and pregnancy status (p = 0.022). Conclusion: Our findings underscore the urgent need of educational and family planning programs that may help prevent detrimental outcomes of ZIKV infection in an endemic area of Brazil.

Resumen Introducción: México registra aumento de las cesáreas e inequidad y desigualdad en la distribución de recursos para la atención obstétrica. Objetivo: Identificar las entidades y municipios en México que concentran la demanda de atención obstétrica y tasas de cesáreas y su relación con los recursos en salud y mujeres en edad fértil (MEF). Método: Se registraron los nacimientos del periodo 2008-2017, agrupados en cinco estratos municipales, y los recursos en salud y MEF de 2017. Resultados: La tasa nacional de cesáreas 2008-2017 fue de 45.3/100 nacimientos; 95 y 97 % de los nacimientos y cesáreas se concentraron en el estrato muy alto (470 municipios), en el cual se utilizó 80 % o más de los recursos en salud y destacó la sobreutilización. La densidad de recursos en salud destinados a las MEF reflejó inequidad y desigualdad. Conclusiones: La alta concentración de la demanda obstétrica y oferta de los recursos en salud pudiera conllevar mayor recurrencia a la cesárea. En las políticas de reducción de cesáreas es necesario considerar la organización y administración adecuadas de los recursos en salud.
Abstract Introduction: In Mexico, there is an increase in the number of C-sections, as well as inequity and inequality in the distribution of resources for obstetric care. Objective: To identify the states and municipalities in Mexico that concentrate the demand for obstetric care and the C-section rates and their relationship with health resources and women of childbearing age (WCBA). Method: Births of the 2008-2017 period were recorded, grouped into five municipal strata, as well as 2017 health resources and WCBA. Results: The 2008-2017 national rate of C-sections was 45.3/100 births; 95 and 97 % of births and C-sections were concentrated in the very high stratum, where 80 % or more of health resources were used, with overuse standing out. The density of health resources assigned to WCBAs reflected inequity and inequality Conclusions: The high concentration of obstetric demand and health resources supply could entail a higher recurrence of C-sections. Policies for C-section reduction should consider proper organization and administration of health resources.

@#This study aims to provide detailed information on the role of the following social determinants (i.e. education, occupation, place of residence, marital and economic status) in the acquisition of HIV knowledge among women of childbearing age (15-49 years old). The study uses secondary data from the 2012 Indonesian Demographic and Health Survey (IDHS). The IDHS used a quantitative analytical approach with a cross-sectional study design and multi-stage stratified sampling. The sample included 1,335 women aged 15 to 49 years old living in South Sumatra Province, Indonesia. Descriptive analysis, ANOVA, and t-test and multiple logistic regressions were performed in this study. The results show one out of two women have little HIV knowledge. The more highly educated women were positively associated with a greater degree of knowledge related to comprehensive knowledge related to HIV (AOR: 3.7, 2.2-6.2, p.<0.05), HIV prevention (AOR:16.6, 1.8-153.9, p <0.05), transmission from mother to child (AOR:11.1, 3.3-36.9, p <0.05), HIV misconceptions (AOR:5.1, 1.1-23.1, p <0.05) and HIV services (AOR:5.7, 2.8-11.4, p < 0.05). In addition, the women lived in urban areas had more knowledge related to HIV prevention and transmission (AOR: 3.36, 1.8-6.2, p <0.05), and knowledge about mother-to-child of HIV transmission (AOR: 3.2, 1.8-5.5, p <0.05) compared to those who lived in rural areas. To conclude, education level was found to be the dominant factor associated with knowledge of HIV across all categories of knowledge after controlling by other determinants, age, marital status, working status and residence. HIV awareness and comprehensive HIV information among women who are considered to be in a low-risk group for HIV infection should be integrated with formal education as well as in maternal health services, particularly in rural areas.
ABSTRACT
Objective To analyze the infection of human parvovirus B19 among women of childbearing age in Xiangyang City, and to provide a reference for pregnant women's health care. Methods A total of 303 women of childbearing age in Xiangyang City from 2018 to 2019 were selected as the research subjects. B19 virus DNA in serum of the subjects was detected by nested PCR technology. The differences in the detection rate of B19 viral DNA among normal pregnancy, abnormal pregnancy, and infertility serum were statistically analyzed. The differences in the detection rate of B19 virus DNA among women of childbearing age at different ages were compared. Results The detection rate of B19 viral DNA in all 303 women of child-bearing age was 27.72%. The detection rate of B19 virus DNA in 26-35 year old women was higher than that in other age groups. The detection rate of B19 virus DNA in abnormal pregnancy group was significantly higher than that in normal pregnancy group (P <0.05). Conclusion The detection rate of B19 virus DNA in abnormal pregnancy and infertility group was significantly higher than that in normal pregnancy group, with the detection rate of B19 virus in 26-35 year old women of childbearing age being the highest among all age groups. It is necessary to strengthen the screening of B19 virus in pregnant women of childbearing age in this region to reduce its impact on fetal abortion.
ABSTRACT
Objective To investigate the service needs in relation to the related behavioral characteristics and reproductive health service for women receiving induced abortion in childbearing age in Wenzhou, providing reference for the protection of reproductive health in women of childbearing age. Methods A questionnaire survey was conducted among a total of 1 065 women of childbearing age who received artificial abortion in 12 medical institutions and maternal and child health care institutions in Wenzhou. Results Of the 1 065 women, 456 (42.82%) were under 24 years old, 609 (57.18%) were over 25 years old.815 (76.53%) with high school / technical secondary school degree or below, 250 (23.47%) with college degree or above.448 unmarried (42.07%), 617 married (57.93%).484 (45.45%) of first abortion and 581 (54.55%) of repeated abortion.Among the direct causes of abortion, 244 (54.46%) were not contraception, 382 (61.91%) were contraception failure.There was a significant difference in the direct causes of induced abortion among women with different marital status(χ2＝28.128, P < 0.05).67.51% of the surveyed women hoped that the family planning clinic would provide contraceptive and reproductive health consulting services after abortion. Conclusion Women of childbearing age with induced abortion in Wenzhou have low education level, high rate of repeated abortion, lack of contraceptive knowledge and high demand for contraceptive and reproductive health consulting services.Therefore, it is necessary to improve reproductive health education, popularize contraceptive knowledge, reduce abortion rate and promote reproductive health.

Objective @#To learn the incidence trend of gestational diabetes mellitus (GDM) among women of childbearing age in Hangzhou from 2009 to 2018, providing evidence for GDM prevention and control.@*Methods@#The information of GDM cases aged 15 to 49 years in Hangzhou from 2009 to 2018 was extracted from Zhejiang non-communicable diseases surveillance system. The crude and age-standardized (by national standard population in 2000) incidence rate of GDM were calculated, the annual change percentage (APC) and the average APC (AAPC) of GDM incidence rate were calculated to understand the trend of incidence in different age groups and areas. @*Results@#A total of 45 519 cases of GDM were reported in Hangzhou from 2009 to 2018. The crude and age-standardized incidence rates were 248.04/100 000 and 158.52/100 000, respectively, both showed upward trends with 59.7% and 56.4% in AAPC (both P<0.05). The APCs of crude and age-standardized incidence rates of GDM were 139.76% and 134.60% from 2009 to 2012, 30.35% and 27.65% from 2012 to 2018, which all had increasing trends (all P<0.05). There were upward trends in GDM incidence in each age groups of 15-24, 25-29, 30-34, 35-39 and 40-49 years old (all P<0.05). The AAPC of GDM incidence in 40-49 year-old women was 65.3% and ranked the first among all the age groups. The age-standardized incidence rate of GDM increased more in rural areas (AAPC=66.0%) than in urban areas (AAPC=53.4%). @*Conclusion@# A rising trend in GDM incidence among women aged 15-49 years in Hangzhou has been found in recent ten years, especially in women aged 40-49 years and lived in rural areas.
ABSTRACT
Background@#Thyroid autoimmunity (TAI) is prevalent among women of reproductive age and associated with adverse pregnancy outcomes. This study aimed to investigate the association between iron nutritional status and the prevalence of TAI in women during the first trimester of pregnancy and in non-pregnant women of childbearing age.@*Methods@#Cross-sectional analysis of 7463 pregnant women during the first trimester of pregnancy and 2185 non-pregnant women of childbearing age nested within the sub-clinical hypothyroid in early pregnancy study, a prospective collection of pregnant and non-pregnant women’s data, was conducted in Liaoning province of China between 2012 and 2015. Serum thyrotropin, free thyroxine, thyroid peroxidase antibodies (TPOAbs), thyroglobulin antibodies (TgAbs), serum ferritin, and urinary iodine were measured. Iron deficiency (ID) was defined as serum ferritin <15 μg/L and iron overload (IO) was defined as ferritin >150 μg/L. TPOAb-positive was defined as >34 U/mL and TgAb-positive was defined as >115 U/mL. Multilevel logistic regression was conducted to examine the association between TAI and different iron nutritional status after adjusting for potential confounders.@*Results@#The prevalence of isolated TPOAb-positive was markedly higher in women with ID than those without ID, in both pregnant and non-pregnant women (6.28% vs. 3.23%, χ2 = 10.264, P = 0.002; 6.25% vs. 3.70%, χ2 = 3,791, P = 0.044; respectively). After adjusting for confounders and the cluster effect of hospitals, ID remained associated with TPOAb-positive in pregnant and non-pregnant women (odds ratio [OR]: 2.111, 95% confidence interval [CI]: 1.241–3.591, P = 0.006; and OR: 1.822, 95% CI: 1.011–3.282, P = 0.046, respectively).@*Conclusion@#ID was associated with a higher prevalence of isolated TPOAbs-positive, but not with isolated TgAb-positive, in both pregnant women during the first trimester of pregnancy and non-pregnant women of childbearing age, while IO was not associated with either isolated TPOAb-positive or isolated TgAb-positive.@*Clinical trial registration@#ChiCTR-TRC-13003805, http://www.chictr.org.cn/index.aspx.
ABSTRACT
The clinical manifestations of polycystic ovary syndrome(PCOS)are highly heterogeneous.The diagnosis and treatment of PCOS are still controversial,and the treatment methods are different.In 2018,the Gynecological Endocrinology Group of Chinese Med⁃ical Association of Obstetrics and Gynecology orga⁃nized domestic experts to formulate the "Guidelines for Diagnosis and Treatment of Polycystic Ovarian Syn⁃drome" in China.This article will interpret the diag⁃nosis criteria and the evidence of this Guidelines for childbearing age women by combining with foreign consensus and literature.
ABSTRACT
Bisphosphonates ( BPs) are bone resorption inhibitors, which are increasingly used in the treatment of bone metabolic diseases in women of childbearing age. It is unclear whether the use of BPs in women of childbearing age will affect the health of their offspring. This article retrieved 66 reports in the past 40 years by searching on the databases of Pubmed, Embase, Ovid, Medline and so on. A number of reports found that BPs may be responsible for shortening gestational age, increasing spontaneous abortion, and decreasing neonatal birth weight. Three women's offsprings were found to have abnormal blood calcium after birth. Cases of skeletal malformations include two bilateral talipes equinus, one Apert's syndrome and one rickets. However, there have been many reports of no reproductive abnormalities or abnormal blood calcium level. Occasionally, children breast-fed by women who had received BPs have had a transient hypocalcemia. There is currently insufficient evidence to confirm that BPs can cause significant reproductive malformations during pregnancy or pre-pregnancy. However, due to the long-term presence of BPs in the bones, women of childbearing age who have a need for pregnancy should choose to use these drugs with caution.
ABSTRACT
Objective To investigate the screening and gene test of thalassemia in couples of childbearing age in Quanzhou City Fujian Province.Methods A prospective design was used to collect 41 026 pairs of marriage and excellent blood samples from 12 counties in Quanzhou City,Fujian Province from July 2017 to July 2018.To analyze screened the genetic test results and genotyping of positive thalassemia couples.Firstly,the erythrocyte mean corpuscular volume (MCV) and erythrocyte mean corpuscular hemoglobin (MCH) were used for primary screening.Both sides of the couple were performed hemoglobin electrophoresis when at least one of the couples was screened positive.Couples were performed thalassemia gene detection when blood routine or hemoglobin electrophoresis of the couples was positive.The characteristics of genotypes,homologous carriers and distribution of gene mutations in Quanzhou City were analyzed.Results Among 41 026 couples of childbearing age,4 470 couples had abnormal blood routine examination results in at least one of the couples,the rate of positive screening was 10.90％.There were 952 couples who represented abnormal blood routine or hemoglobin abnormal electrophoresis.Totally 658 cases were diagnosed as thalassemia after thalassemia gene detection,and the diagnosis rate was 34.56％.Totally 493 cases of α-thalassemia were detected,and the higher genotypes were:--SEA/αα,-α3.7/αα and ααQS/αα;and 155 cases of β-thalassemia were detected,and the higher genotypes were:IVS-Ⅱ-654/N,CD41-42/N,CD17/N,βE/N,-28/N;10 cases of α complex β thalassemia were detected.Totally 56 high-risk couples with homologous thalassemia gene were detected,including 50 pairs of homologous α-thalassemia,4 pairs of homologous β-thalassemia,and 2 pairs of homologous couples with α complex β thalassemia.The rate of diagnosis and detection rate of homologous thalassemia in different counties of Quanzhou were quite different (x2 =41.939,21.129,P ＜ 0.05).Among them,the rate of diagnosis in Dehua County was the highest (53.13％,85/160),followed by Yongchun County (39.38％,63/160) and Nan'an City (37.73％,123/326).In addition,the detection rate of homologous thalassemia in Dehua County was the highest (15.00％,12/80),followed by Anxi County (8.44％,13/154) and Yongchun County (7.50％,6/80).Conclusions The incidence of thalassemia in couples of childbearing age in Quanzhou is higher,mainly due to α-thahssemia.The high-risk type of homologous carrier is present in α-thalassemia,which should be paid attention to the prevention and control of thalassemia.
ABSTRACT
The mother-to-child transmission(MTCT) of hepatitis B virus (HBV) is the dominant cause of chronic HBV infection. In order to achieve the goal of "zero" MTCT before pregnancy, during pregnancy, and after pregnancy; standardized management for hepatitis HBV infection in women of childbearing age should be regulated. The content of this consensus includes: screening and treatment of HBV in pregnant women and women of childbearing age, treatment of hepatitis B during pregnancy, preventive measures and evaluation of combined immunization of hepatitis B immunoglobulin and hepatitis B vaccine in newborns, anti-viral therapy for all pregnant women with a high HBV DNA level and post-partum period related management. In addition, 16 recommendations were formed for clinicians to standardize the clinical management of HBV infection in women of child-bearing age.
